Abstract:

Case reports detailing diagnosis and effective treatment of pisotriquetral loose bodies are scarce. This article describes an even rarer case of bilateral pisotriquetral joint loose bodies, explores the relative diagnostic roles of magnetic resonance imaging versus computed tomography, and outlines effective strategies used for the management of this condition drawn from the literature and our own experience.

Abstract:

We report on a patient with a rare case of bilateral tension pneumothorax that occurred after acupuncture. A 69-year-old large-bodied man, who otherwise had no risk factors for spontaneous pneumothorax, presented with chest pressure, cold sweats and shortness of breath. Immediately after bilateral pneumothorax had been identified on a chest radiograph in the emergency room, his blood pressure and percutaneous oxygen saturation suddenly decreased to 78 mm Hg and 86%, respectively. We confirmed deterioration in his cardiopulmonary status and diagnosed bilateral tension pneumothorax. We punctured his chest bilaterally and inserted chest tubes for drainage. His vital signs promptly recovered. After the bilateral puncture and drainage, we learnt that he had been treated with acupuncture on his upper back. We finally diagnosed a bilateral tension pneumothorax based on the symptoms that appeared 8 h after the acupuncture. Because the patient had no risk factors for spontaneous pneumothorax, no alternative diagnosis was proposed. We recommend that patients receiving acupuncture around the chest wall must be adequately informed of the possibility of complications and expected symptoms, as a definitive diagnosis can be difficult without complete information.

Abstract:

Fibrodysplasia ossificans progressiva (FOP) is an extremely rare skeletal dysplasia with characteristic imaging and clinical findings, which includes bilateral hallux valgus, monophalangic great toes with short and stout first metatarsals, heterotopic ossification of muscles and connective tissues, short broad femoral necks, pseudo exostoses, short and stout first metacarpals, C2-C7 facet joint fusion, large posterior elements, and tall narrow vertebral bodies. We present a case of an 8-year-old male child who came with complaints of multiple progressive hard swellings over the neck, chest, and abdomen with restriction of movements for a duration of 2 years and deformity of great toe on both sides since birth. On clinical examination, the patient had multiple non-tender hard bony swellings in neck, chest, and abdominal wall with bilateral hallux valgus deformity. Radiographic examination revealed well- defined rib-like ectopic osseous outgrowths in the posterior aspect of neck, soft tissues of chest and abdominal wall, bilateral hallux valgus, monophalangic great toe and short first metatarsals with normal cervical vertebral bodies, posterior elements, short first metacarpals bilaterally, and pseudo exostoses in medial aspect of upper one-third of both tibia. With the above classic findings, the diagnosis of FOP was made. Early diagnosis of the condition is very important in these cases as intramuscular injections, biopsies, and trivial trauma can exacerbate the condition with painful flare-ups.

Abstract:

The case of a patient who suffered from progressive amnesia, depressive humor, language and visuospatial disturbances, and hallucination episodies with interference at the daily living activities is reported. She had moderate neuropsichological diffuse deficits at the first examination, especially at the executive and visuo-constructive functions. Her cerebrospinal fluid test presented high total protein. Magnetic resonance image showed slight white matter increase in periventricular, semi-oval center bilateral and left external capsule regions, besides light frontal and parietal lobe atrophy, bilaterally. Brain single photon emission computerized tomography revealed both a bilateral moderate frontal and a severe parietal lobe hypoperfusion, especially on the left side. Macroscopic examination showed cortical atrophy, severe on the frontal, moderate on the parietal and mild on the posterior third temporal lobes, bilaterally. There was a slight atrophy on the neostriatum in the basal ganglia. The histopathological findings of the autopsy showed severe neuronal loss with intensive gemioscytic gliosis and variable degrees of status spongiosus in cortical layer. Hematoxylin-eosin and Bielschowsky staining did not show neuronal swelling (balooned cell), argyrophilic inclusion (Pick's bodies), neurofibrillary tangles nor senile plaques. Immunohistochemical staining for anti-ubiquitin, anti-tau, anti-beta-amyloide, and anti-prion protein were tested negative.

Abstract:

At least one polar body, almost invariably the second, persists intact to the early blastocyst stage in nearly two-thirds of mouse conceptuses of the PO strain. The distribution in early blastocysts of these surviving polar bodies was highly non-random. Most not only lay in the mid-region of the embryonic-abembryonic axis but, on discovering that early blastocysts are bilaterally rather than radially symmetrical about this axis, were found to align with the bilateral axis. Cell marking experiments failed to detect movement of polar bodies relative to the surface of the conceptus during either cleavage or blastulation. That the distribution of degenerating polar bodies and their presumed debris was similar to intact ones also argued against their motility, as did the finding that at all stages second polar bodies were attached to conceptuses by a thin, extensible, weakly elastic ‘tether’. Although the transfer of small fluorochromes between them was rarely observed beyond second cleavage, the second polar body and conceptus could remain coupled ionically up to the blastocyst stage. It is concluded that the second polar body normally remains attached to the conceptus through persistence of the intercellular bridge formed during its abstriction, and therefore provides an enduring marker of the animal pole of the zygote. Hence, according to the distribution of polar bodies, the axis of bilateral symmetry of the early blastocysts is normally aligned with the animal-vegetal axis of the zygote and its embryonic-abembryonic axis is orthogonal to it. Such relationships suggest that, at least in undisturbed development, specification of the axes of the blastocyst depends on spatial patterning of the zygote.

Abstract:

A 12-year-old boy with suprasellar germinoma complicated by hydrocephalus was found to have dorsal midbrain syndrome and bilateral compressive optic neuropathy. Following a third ventricular neuroendoscopic biopsy and the initiation of chemotherapy, a follow-up magnetic resonance imaging scan of the brain showed significant regression of the tumor with resolution of hydrocephalus. On smooth pursuit, there was significant improvement in upgaze. However, light-near dissociation of his pupillary defect was persistent. Fundal examination showed persistent temporal pallor of the optic discs bilaterally, associated with a suboptimal best-corrected visual acuity of 20/40 and bilateral centrocecal scotoma.The differential recovery of neuronal function following relief of compression is poorly understood. In this case, both the optic nerve and pretectal axonal fibers responsible for pupillary reflex, with their neuronal cell bodies residing outside the direct compressive site at the midbrain, showed poor functional recovery. However, relief of pressure at the rostral interstitial medial longitudinal fasciculus and posterior commissure nuclear complexes resulted in significant clinical improvement in upgaze. This case suggests that, for neurons, axons are apparently more susceptible to pressure than cell bodies. The predominant transmission of nerve impulses takes place through the length of axons, and thus is more sensitive to pressure changes, with the associated microvascular compromise and demyelination.

Abstract:

Background:The anatomical foot–ankle complex facilitates advancement of the stance limb through foot rockers and late-stance power generation during walking, but this mechanism is altered for persons with bilateral transtibial amputation when using passive prostheses.Objectives:To study the effects of bilateral foot and ankle immobilization on able-bodied gait to serve as a model for understanding gait of persons with bilateral transtibial amputation and associated compensatory mechanisms.Study design:Comparative analysis.Methods:Nine able-bodied persons walked at self-selected slow, normal, and fast speeds. They performed trials unaltered and when fitted with bilateral foot and ankle–immobilizing casts. Data from 10 individuals with bilateral transtibial amputation walking at self-selected fast speeds were used for qualitative comparison.Results:The average speeds for the able-bodied fast speed cast and normal speed no-cast trials were similar and were compared with bilateral transtibial amputation data. The able-bodied cast condition data more closely matched bilateral transtibial amputation data than the no-cast data. Ankle range-of-motion and power generation at pre-swing in the cast condition were markedly decreased, while trunk lateral flexion and transverse rotation range-of-motion and peak hip power generation increased.Conclusion:Results suggest that the absence of active ankle range-of-motion and power generation contributes to the development of characteristic compensatory gait mechanisms displayed by persons with bilateral transtibial amputation.Clinical relevanceThis study helps to improve understanding of compensatory mechanisms resulting from reduced foot and ankle joint motion to inform lower limb prosthesis design and function for improving gait quality of individuals with bilateral transtibial amputation.

Abstract:

SummaryThe clinical and radiological findings of three related Miniature Poodles with multiple enchondromatosis (Ollier’s disease) are presented. Persisting, in part ossified growth plate cartilage foci were found bilaterally in the humerus, radius, ulna, femur, tibia and fibula of each dog and in one dog in some metacarpal and metatarsal bones. The ribs and many vertebral bodies were also affected. There was evidently no bone formation in the sternebrae. All three dogs first attracted attention at the ages of four to six months, with spontaneous bilateral femoral neck fractures. The mode of inheritance of the condition is not yet clear, but based on the known pedigree data a dominant effect appears unlikely.

Abstract:

We report a case of 10-year-male child diagnosed as acute pancreatitis with deranged liver and renal functions, who presented with sudden onset bilateral painless vision loss 2 days after initial diagnosis. Neuroophthalmological examination including deep tendon reflex, plantar reflex, visual acuity, pupillary reflexes, and fundus was performed. Magnetic resonance imaging brain demonstrated features of hemorrhagic infarction involving bilateral lateral geniculate bodies (LGBs) and posterior end of optic tracts. Two major causes of bilateral LGBs lesions include vascular ischemia and osmotic demyelination. Possible mechanism of involvement of bilateral LGBs in present case is coagulopathy in the settings of acute pancreatitis attributed to pro-thrombotic state leading to microvascular occlusions.

Abstract:

Abstract Fibroepithelial lesions are uncommon in the male breast. Most published reports describe phyllodes tumors. Fibroadenomas are very common in female breasts, but are exceedingly rare in the male breast. Gynecomastia and/or lobular differentiation have been known to coexist in both types of fibroepithelial lesions in men. We report an exceptional case of recurrent, bilateral fibroadenomas in a man under treatment for prostatic carcinoma. Intracytoplasmic inclusion bodies in stromal cells identical to those seen in infantile digital fibromatosis were identified in one fibroadenoma. To the best of our knowledge, this is the first reported case of bilaterally occurring fibroadenomas in the male breast, one of which also contained digital fibroma– like inclusions, a second unreported phenomenon.

Abstract:

Gravity models are used to explain bilateral flows related to the sizes of bilateral partners, a measure of distance between them and other influences on interaction costs. The underlying idea is rather simple. The greater the masses of two bodies and the smaller the distance between them, the stronger they attract each other. This concept is applied to several research topics such as trade, migration or foreign direct investment. Even though the basic idea of gravity models is rather simple, they can become very complex when it comes to the choice of models or estimation methods. The package \textbf{gravity} targets to provide \proglang{R} users with the functions necessary to execute the most common estimation methods for gravity models, especially for cross-sectional data. Gravitätsmodelle werden verwendet, um bilaterale Ströme zu erklären. Dabei werden sowohl die Größen und die Distanz der jeweiligen Partner als auch weitere Einflussfaktoren zur Erklärung herangezogen. Die zugrundeliegende Idee dieser Modelle beruht auf dem Gravitätsprinzip. Je schwerer zwei Körper und je kleiner deren Distanz zueinander, desto stärker ist ihre gegenseitige Anziehungskraft. Dieses Konzept wird auf verschiedene Forschungsreiche angewendet, so zum Beispiel Handel, Migration und ausländische Direktinvestitionen. Auch wenn die zugrundeliegende Idee von Gravitätsmodellen eher einfach ist, so kann deren Schätzung je nach Wahl des zugrundegelegten ökonomischen Zusammenhangs komplex werden. Das Paket \textbf{gravity} ermöglicht es \proglang{R}-Nutzern die gängigsten Verfahren für Gravitätsmodelle in der Querschnittsanalyse zu verwenden.

Abstract:

Abstract: This report provides an outline of the system of bilateral bodies first set up in Italy in the 1980s to provide protection and income support for workers in artisan firms. Jointly run by employers’ associations and trade union representatives, these bodies provide a forum for dispute resolution as well as a system for administering the employers’ contributions negotiated in collective agreements. The authors argue that bilateral bodies represent an innovative approach to labour protection in small and micro enterprises and provide a useful means for identifying appropriate measures as part of a decentralised approach reflecting the needs of both employers and workers in artisan firms not covered by collective agreements for large-scale industry. Bilateralism is likely to play an increasingly important role pursuant to the labour market reform recently enacted in Italy.

Abstract:

Introduction and Aim: Retained intracorporeal textile products (gossypiboma-textiloma) are undesired and accidental surgical results for both patients and surgeons, which are underreported because of medicolegal remifications. Fourteen textiloma cases, who had been treated or whose treatment procedures had been followed-up personally by two general surgeons in a period of 27 years almost during their whole professional lives were presented to describe and define the clinical and pathological characteristics. Material and Methods: Patient characteristics including gender and age, areas of location within the body, time intervals until diagnosis, clinical presentations and complaints, treatment modalities, complications, causative surgical interventions, and diagnostic approaches were retrospectively evaluated. Results: Nine female and five male patients with a mean age of 43.07 ± 15.23 (median: 45) years at diagnosis were enrolled in the study. Cesarean section in three, inguinal hernioraphy in four, explorative laparotomy because of acute abdomen in one, sigmoid colon resection in one, appendectomy and right salpingoophorectomy in one, etrangulated incisional hernia after a previous surgical intervention because of an ovarian mass in one, thyroidectomy in one, epigastric hernioraphy in one, and bilateral segmental mastectomy with bilateral axillary sentinal lymph node dissection in one were the causative surgical interventions. Locations of textilomas were the abdominal cavity in seven, inguinal surgical wound in four, epigastric surgical wound in one, thyroidectomy lodge in one, and bilateral axillary cavities in one patient. The mean time interval until diagnosis was 14.48 (median: 5.5) months. Dıscussıon: Earlier recognition of foreign bodies can provide a better outcome. Conclusion: Gossypibomas are preventable iatrogenic faults which create severe problems. Strict adherence to the rules of the operation room is a must to keep the tip of the iceberg shut in the Pandora’s box.

Full text

Abstract:

Background: Extramedullary hematopoiesis (EH) is common in patients with ineffective erythropoiesis like thalassemia major (TM). EH commonly involves intra-abdominal organs (e.g., spleen and liver), but rarely involves vertebral bodies. Here, we reviewed images of EH contributing to spinal canal stenosis. Case Description: A 19-year-old male with beta-thalassemia major (TM) presented with pain and bilateral lower extremity neurogenic claudication. Bilaterally, on examination, he had positive straight leg raising to 30°, a loss of the Achilles responses, and decreased pain appreciation in the L5S1 distributions. The lumbar MR showed anterior epidural lobulated mass lesions at L5 and S1, contributing to marked canal stenosis. Following an L5/S1 laminectomy for decompression, the biopsy revealed extramedullary hematopoietic tissue. Conclusion: Patients presenting with the lower extremity symptoms/signs, ranging from low back pain to neurogenic claudication and even paraplegia, may have EH secondary to TM. Treatment options include hypertransfusion, local radiation therapy, and/or surgical decompression.

Abstract:

Bilateral, cervical vagotomy in birds denervates, among other receptors, the carotid bodies. To test whether such neural section removes sensitivity to hypoxia, we measured respiratory, cardiovascular, and blood gas responses to hypoxia at 84-, 70-, and 49-Torr inspiratory O2 partial pressure (PIO2) in five pigeons with intact vagi and in five bilaterally, cervically vagotomized pigeons. Normoxic respiratory frequency (fresp) and expiratory flow rate (VE) were decreased after vagotomy. Intact pigeons showed large increases in VE in response to hypoxia, effected mostly by increases in fresp. VE also increased greatly in response to hypoxia in vagotomized pigeons, but increases were largely the result of tidal volume. O2 consumption, CO2 production, and respiratory exchange ratio increased slightly in all pigeons during hypoxia. Normoxic heart rate was greater after vagotomy; cardiac output increased in all pigeons in response to hypoxia, but stroke volume increased only in intact pigeons. During normoxia, arterial and mixed venous O2 partial pressure, O2 concentration, and pH were lower and arterial and mixed venous CO2 partial pressure was higher, after vagotomy. In all pigeons during hypoxia, arterial and mixed venous O2 and CO2 partial pressure and O2 concentration decreased and arterial and mixed venous pH increased; changes were roughly parallel in intact and vagotomized pigeons. The arteriovenous O2 concentration differences during normoxia and hypoxia were similar in all pigeons. We conclude that bilateral, cervical vagotomy in the pigeon causes hypoventilation and tachycardia during normoxia, but strong respiratory and cardiovascular responses to hypoxia are still present.

Abstract:

The aim of this study was to develop a normative sample of step frequency and step length during maximal sprinting in amputee sprinters. We analyzed elite-level 100-m races of 255 amputees and 93 able-bodied sprinters, both men and women, from publicly-available Internet broadcasts. For each sprinter’s run, the average forward velocity, step frequency, and step length over the 100-m distance were analyzed by using the official record and number of steps in each race. The average forward velocity was greatest in able-bodied sprinters (10.04 ± 0.17 m/s), followed by bilateral transtibial (8.77 ± 0.27 m/s), unilateral transtibial (8.65 ± 0.30 m/s), and transfemoral amputee sprinters (7.65 ± 0.38 m/s) in men. Differences in velocity among 4 groups were associated with step length (able-bodied vs transtibial amputees) or both step frequency and step length (able-bodied vs transfemoral amputees). Although we also found that the velocity was greatest in able-bodied sprinters (9.10 ± 0.14 m/s), followed by unilateral transtibial (7.08 ± 0.26 m/s), bilateral transtibial (7.06 ± 0.48 m/s), and transfemoral amputee sprinters (5.92 ± 0.33 m/s) in women, the differences in the velocity among the groups were associated with both step frequency and step length. Current results suggest that spatiotemporal parameters during a 100-m race of amputee sprinters is varied by amputation levels and sex.

Abstract:

A dog was referred to Alta Vista Animal Hospital with a porcupine quill penetrating the right ventricle. The presenting complaint was tachypnea and dyspnea secondary to bilateral pneumothorax. Computed tomography revealed bilateral pneumothorax without evidence of quills. A median sternotomy was performed and the quill was removed. The dog recovered uneventfully. Quill injuries are common in dogs; however, intracardiac quill migration is rare. Dogs without evidence of severe cardiac injury secondary to intracardiac foreign bodies may have a good prognosis.

Animal bodies in general and faces in particular show mirror symmetry with respect to the median-sagittal plane, with exceptions rarely occurring. Bilateral symmetry to the median sagittal plane of the body also evolved very early. From an evolutionary point of view, it should therefore have fundamental advantages, e.g., more effective locomotion and chewing abilities. On the other hand, the recognition of bilaterally symmetric patterns is an important module in our visual perception. In particular, the recognition of faces with different spatial orientations and their identification is strongly related to the recognition of bilateral symmetry. Maxillofacial surgery and Dentistry affect effective masticatory function and perceived symmetry of the lower third of the face. Both disciplines have the ability to eliminate or mitigate asymmetries with respect to form and function. In our review, we will demonstrate symmetric structures from single teeth to the whole face. We will further describe different approaches to quantify cranial, facial and dental asymmetries by using either landmarks or 3D surface models. Severe facial asymmetries are usually caused by malformations such as hemifacial hyperplasia, injury or other diseases such as Noma or head and neck cancer. This could be an important sociobiological reason for a correlation between asymmetry and perceived disfigurement. The aim of our review is to show how facial symmetry and attractiveness are related and in what way dental and facial structures and the symmetry of their shape and color influence aesthetic perception. We will further demonstrate how modern technology can be used to improve symmetry in facial prostheses and maxillofacial surgery.

Abstract:

We report atypical magnetic resonance imaging (MRI) lesions in a case of Wernicke encephalopathy. The patient presented with isolated anterograde amnesia following a partial colectomy complicated by peritonitis. Fluid-attenuated inversion recovery and T2 MRI sequences were normal. However, bilateral contrast enhancement of mammillary bodies was shown on T1 gadolinium-enhanced sequences. Blood tests revealed thiamine deficiency. The diagnosis of Wernicke encephalopathy was made and thiamine supplementation was given, resulting in complete recovery of the memory functions.

Abstract:

Context: In sprint events, the first 2 steps are used to accelerate the center of mass horizontally and vertically. Amputee athletes cannot actively generate energy with their running-specific prosthesis. It is likely that sprint acceleration mechanics, including step asymmetry, are altered compared with able-bodied athletes. Purpose: To investigate spatiotemporal and kinetic variables of amputee compared with able-bodied sprinters. Methods: Kinematic and kinetic data of the first and second stance were collected from 15 able-bodied and 7 amputee sprinters (2 unilateral transfemoral, 4 unilateral transtibial, and 1 bilateral transtibial) with a motion-capture system (250 Hz) and 2 force plates (1000 Hz). In addition, bilateral asymmetry was quantified and compared between groups. Results: Compared with able-bodied athletes, amputee athletes demonstrated significantly lower performance values for 5- and 10-m times. Step length, step velocity, and step frequency were decreased and contact times increased. Peak horizontal force and relative change of horizontal velocity were decreased in both stances. Peak vertical force and relative change of vertical velocity were lower for the amputee than the able-bodied group during the first stance but significantly higher during the second stance. During the first stance, able-bodied and amputee sprinters displayed a similar orientation of the ground-reaction-force vector, which became more vertically orientated in the amputee group during second stance. Amputee sprinters showed significantly greater asymmetry magnitudes for vertical force kinetics compared with able-bodietd athletes. Conclusion: A running-specific prosthesis does not replicate the function of the biological limb well in the early acceleration phase.

Abstract:

This paper presents a complete study on the collision without friction of two rigid bodies with and without bilateral constraints. Our goal is to obtain the same formulae for the impulse, the energy of the lost velocities, and the loss of kinetic energy as in the case of the collision of two particles. The study is performed with the aid of the notion of inertance. The dependence on the constraints is given by the inertances. The calculations are realized using the results from the theory of screws (plückerian coordinates). The obtained formulae are general, written in matrix form, and they may be easily used in any practical problem. We give the general algorithms for the collision of two rigid bodies with and without bilateral constraints. The equality of the coefficients of restitution in the Newton, Poisson, and energetic models is also proved. The numerical examples highlight the theory.

Abstract:

Background. Wernicke’s Encephalopathy (WE) is a clinical diagnosis with serious neurological consequences. Its occurrence is underestimated in nonalcoholics and is uncommon in adolescents. We aim to draw the attention to a rare case, which had additional clinical and radiological features.Case. A 16-year-old girl presented with three-week history of vomiting secondary to intestinal obstruction. She developed diplopia soon after hospitalization. Neurological evaluation revealed restriction of bilateral lateral recti with horizontal nystagmus, and bilateral limb dysmetria. Brain MRI was normal. She had prompt improvement to thiamine. Four months later, she presented with headache, bilateral severe deafness, and tinnitus. Clinically, she had severe sensorineural hearing loss, bilateral lateral recti paresis, and gait ataxia. CT head showed bilateral caudate nucleus hypodensities. MRI brain revealed gadolinium enhancement of mamillary bodies and vermis. She had significant improvement after IV thiamine. Headache completely resolved while the ocular movements, hearing, and tinnitus improved partially in 72 hours.Conclusions. Recurrent WE in adolescence is uncommon. Headache, tinnitus, and deafness are rare clinical features. Although MRI study shows typical features of WE, the presence of bilateral caudate nuclei hypodensities on CT scan is uncommon. Prompt treatment with thiamine is warranted in suspected cases to prevent permanent neurological sequelae.

Abstract:

PURPOSE: To evaluate the in vivo alterations on ketone bodies metabolism after cerebral ischemia/reperfusion through an experimental model of brain ischemia induced by simple occlusion of common carotid arteries (CCAs) in Wistar rats. METHODS: Forty-eight male Wistar rats were randomly distributed on two groups (S - Sham; T - Test) and further redistributed into four times sets of study. After bilateral occlusion of CCAs for 30min, the animals of group T were allowed reperfusion for 0, 5, 10 and 15min. Samples of cerebral tissue and systemic arterial blood were collected and the metabolites acetoacetate (ACT) and beta-hydroxybutyrate (BHB) were determined. RESULTS: Cerebral ACT and BHB levels increased significantly in Group T after 30min of carotid occlusion (time 0). The highest brain ketone bodies (ACT+BHB) concentration was verified at 5min of reperfusion, decreasing after 10min of recirculation. Systemic ketone bodies levels increased similarly between test and sham groups. Group S demonstrated a significant increase in cerebral and systemic ACT and BHB concentrations mainly after 40-45min of study. CONCLUSIONS: The partial transient acute global brain ischemia induced by the bilateral carotid occlusion in Wistar rats triggered ketogenesis probably due to a central stimulation of catecholamine secretion. There was an increased cerebral uptake of ketone bodies following brain ischemia, reaffirming these metabolites as alternative energy substrates under conditions of cerebral metabolic stress as well as its potential role on neuroprotection. The greatest changes in ketone bodies metabolism were verified at initial minutes of recirculation as a result of the reperfusion injury phenomenon.

Abstract:

1. We have studied the carotid body contribution to hypoxic respiratory drive, using a hypoxic/hyperoxic switching technique, and the ventilatory response to intravenous infusion of adenosine, a recently described respiratory stimulant, in five patients with bilateral carotid endarterectomy. 2. The contribution made by the carotid bodies to total ventilatory drive during hypoxia varied from 2.5% to 45.9%. 3. The ventilatory response to adenosine infusion varied from a 7% decrease to a 25% increase in ventilation. 4. Those patients with intact hypoxic ventilatory drive showed respiratory stimulation, whereas of the two patients with attenuated chemoreflexes, one showed no stimulation and the other depression of ventilation in response to adenosine infusion. 5. We conclude that adenosine exerts its respiratory stimulant effect via an action on the peripheral chemoreceptors. This may coexist with a centrally mediated respiratory depression that is masked when the carotid bodies are intact.

Abstract:

A two-year-old, Irish Wolfhound dog presented with a history of progressive neurological signs. Neurological exam revealed disorientation, absence of menace response, reduction of right nasal sensation, hypermetria and ataxia with reduction of proprioception in all four limbs. MRI findings were compatible with laminar neuronal necrosis and possible bilateral cortical cerebral atrophy. Grossly, a severe bilateral reduction of the gray matter with flattening of gyri, mainly in frontal and parietal cerebral areas, was observed. Histologically, multiple, segmental, bilateral, and symmetric areas of neuronal loss, necrosis and degeneration, in a laminar pattern, associated with a reactive gliosis were observed. Immunohistochemical studies showed severe reduction of neuronal bodies, proliferation and hypertrophy of astrocytes and microglia. Few perivascular B and T cells were demonstrated. Based on these data, we show some of the neuroinflammatory events that occur during CNS repair in a chronic phase of this condition.

Full text

Abstract:

Coronary vasoconstriction is a component of the baroreflex response to bilateral carotid occlusion. The central pathways responsible for this reflex constriction are incompletely understood, but previous studies show that activation of parabrachial nucleus (PBN) elicits coronary vasoconstriction and that PBN shares prominent anatomic connections with other central baroreflex centers, including the nucleus of the tractus solitarius. Therefore, we examined whether PBN plays a role in baroreflex mediated coronary constriction and whether cell bodies rather than fibers passing through this region are involved. Anesthetized cats were instrumented for continuous measurements of heart rate, arterial pressure, and coronary flow velocity. Bilateral carotid occlusion following propranolol and vagotomy increased arterial pressure (63 +/- 10%) and an index of coronary vascular resistance (34 +/- 6%). Bilateral microinjections of lidocaine (1%, 400 nl) into PBN reversibly attenuated the coronary constriction (19 +/- 5%) with little effect on the change in arterial pressure. It was further demonstrated that autoregulatory responses to the increase in pressure could not fully account for the observed changes in coronary constriction. In a separate group of animals, kainic acid (50 mM, 300 nl) abolished the baroreflex increase in coronary resistance (43 +/- 1 vs. -9 +/- 9% after) without affecting the increase in arterial pressure (54 +/- 12% increase before vs. 55 +/- 20% increase after kainic acid). We conclude that PBN is a necessary component of the baroreflex pathway mediating coronary vasoconstriction. Furthermore, cell bodies in PBN, rather than simply fibers passing through that region, participate in the reflex coronary vasoconstriction.

Abstract:

(1) Background: The primary motor cortex (M1) experiences reorganization following spinal cord injury (SCI). However, there is a paucity of research comparing bilateral M1 organization in SCI and questions remain to be answered. We explored the presence of somatotopy within the M1 representation of arm muscles, and determined whether anatomical shifts in these representations occur, and investigated the symmetry in organization between the two hemispheres.; (2) Methods: Transcranial magnetic stimulation (TMS) was used to map the representation of the biceps, flexor carpi radialis and abductor pollicis brevis (APB) bilaterally in nine individuals with chronic incomplete cervical spinal cord injury and nine aged- and handed-matched uninjured controls. TMS was delivered over a 6 × 5 point grid that encompassed M1 using an intensity specific to the resting motor threshold for each muscle tested.; (3) Results: Results indicate that, compared to controls, muscle representations in SCI are shifted medially but preserve a general somatotopic arrangement, and that territory dedicated to the APB muscle is greater.; (4) Conclusions: These findings demonstrate differences in the organization of M1 between able-bodied controls and those with incomplete cervical SCI. This altered organization may have future implications in understanding the functional deficits observed in SCI and rehabilitation techniques aimed at restoring function.

Abstract:

This study aims to examine how the bilateral matching decision making of manufacturing enterprises that are seeking partners in the manufacturing supply chain can be improved by taking into consideration evaluation criteria for organizational quality-specific immunity. This study constructs an evaluation indicator system to measure organizational quality-specific immunity based on immune theory. The system’s evaluation criteria are based on the key components of organizational quality-specific immunity. We also construct bilateral matching evaluation and decision-making models using interval-valued hesitant fuzzy information and bidirectional projection technology (BMIHFIBPT). The interval-valued bilateral fuzzy bidirectional projection technology is applied to solve a combination satisfaction and matching optimization model. Empirical analysis is carried out to assess both the supply and demand sides of representative manufacturing enterprises in the manufacturing supply chain, match the main supply and demand bodies of two subjects, and help manufacturing enterprises select the optimal cooperation partners. The empirical analysis results indicate that the bilateral matching evaluation and decision-making models based on BMIHFIBPT can overcome the lack of information to some extent and help solve interval-valued hesitant fuzzy decision-making problems. In turn, the models can provide a basis for manufacturing enterprises to effectively select the best cooperation partners and conduct bilateral matching decision making in the manufacturing supply chain area that supports organizational quality-specific immunity.

Abstract:

1. Supraspinal relays for vagal afferent modulation of responses of spinal dorsal horn neurons to 50 degrees C heating of the skin were examined by the use of nonselective, reversible local anesthesia or soma-selective, irreversible neurotoxic damage of neural tissue. Eighty-five neurons were isolated in the lumbar spinal dorsal horn of 80 pentobarbital-anesthetized, paralyzed rats. All neurons studied had receptive fields on the glabrous skin of the plantar surface of the ipsilateral hind paw and responded to mechanical stimuli of both low and high intensity as well as noxious thermal stimulation. 2. Intensity-dependent modulation by vagal afferent stimulation (VAS) of neuronal responses to heating of the skin was established. Responses of 40 units were facilitated by low and inhibited by greater intensities of VAS. Another 36 units were only inhibited by VAS, and four were only facilitated. 3. Local anesthesia of the dorsolateral pons by bilateral microinjections of lidocaine (4%, 0.5 microliter) were made to examine the contribution of this area to VAS-produced spinal modulation. The microinjection of lidocaine bilaterally into the ventral locus coeruleus/subcoeruleus (LC/SC) reversibly and significantly attenuated VAS-produced inhibition of unit responses to heat from 63 to 89% of control and abolished VAS-produced facilitation. The microinjection of lidocaine bilaterally into the dorsal LC had no significant effect on VAS-produced modulation of spinal dorsal horn neurons. 4. Ibotenic acid (10 micrograms, 0.5 microliter) was microinjected into the dorsolateral pons to determine the relative contributions of cell bodies in this area to VAS-produced spinal modulation. Unilateral microinjection of ibotenic acid into the LC/SC ipsilateral to the vagus nerve stimulated had no significant effect on VAS-produced inhibition but significantly attenuated VAS-produced facilitation of unit responses to heat. Bilateral microinjections of ibotenic acid significantly attenuated VAS-produced inhibition of unit responses to heat from 48 to 94% of control. 5. Local anesthesia of the medial rostroventral medulla (RVM), primarily the nucleus raphe magnus (NRM), significantly attenuated VAS-produced inhibition of unit responses to heat from 55 to 87% of control but had no significant effect on VAS-produced facilitation. Microinjection of ibotenic acid into the RVM also significantly reduced VAS-produced inhibition of unit responses to heat. No significant change in VAS-produced spinal modulation was found after lidocaine microinjection into areas dorsal to the NRM, the nucleus raphe pallidus, or the olivary nucleus.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract:

The most common malignancy of the eye is metastatic tumors, with choroidal metastases being the majority of them. In women, breast cancer is the most common cause of orbital metastases, and in men, it is lung cancer. Despite the fact that there are efficient treatment options for orbital metastases, the benefit of procedures to detect choroidal metastases is debatable due to the quick progression and poor prognosis of lung cancer. In choroidal metastases resulting from lung cancer, patients are usually presented with decreased sight. Defects in the field of vision, flashes of light and floating bodies generally follow. Treatment options of choroidal metastases include many methods including laser photocoagulation, cryotherapy, chemotherapy, radiotherapy, surgical resection, enucleation and photodynamic therapy. There are reports emphasizing radiotherapy as the most efficient treatment option. In this case report, we sum up the case of a male patient presenting with blurry vision in both eyes, who was subsequently detected to have bilateral choroidal metastatic tumor and was diagnosed with primary lung adenocarcinoma.

Abstract:

We are reporting a rare case of neurosarcoidosis that presented with superior orbital fissure syndrome. A 51-year-old Indian woman who suffered from 2 weeks duration, insidious onset gradually progressive left sided headache limited to forehead, left periorbital pain, diplopia on looking toward left, and numbness on the left forehead was referred to our hospital. Ophthalmic findings included left oculomotor nerve, trochlear nerve and abducens nerve palsies, absent corneal reflex, and loss of touch, pain and temperature sensation in V1 distribution. Brain and orbit magnetic resonance imaging (MRI) showed contrast enhancing area at the left orbital apex with normal optic nerve. Normal CSF analysis. High ESR, and chest x-ray showing non-homogenous patchy opacities in bilateral lung fields leaded us for neoplastic screening. Chest computed tomography (CT) revealed multiple ill-defined irregular lung parenchymal nodular opacities of varying sizes involving bilateral lungs with enlarged mediastinal and bilateral axillary lymph nodes. Elevated angiotensin converting enzyme level was found. Biopsy of the axillary lymph node showed non-caseating granulomatous lymphadenitis with giant cells containing schaumann bodies and asteroid bodies in the cytoplasm. These findings indicating an inflammatory response induced by sarcoidosis. After the initiation of steroid treatment, the patient experienced complete remission without any recurrence. When examining a case presenting with superior orbital fissure syndrome with contrast enhancing MRI lesion at the orbital apex, the additional chest CT to exclude neoplastic lesions can detect pulmonary sarcoidosis and extraneural lesions. These may avoid delays in the diagnosis and management of neurosarcoidosis.

Abstract:

Background: Intensive rehabilitation of individuals with bilateral lower limb loss poses a great challenge to both rehabilitation team and amputees themselves due to unavailability of a sound leg to provide stability in standing and gait. Although gait characteristics of individuals with unilateral transtibial amputations are well documented in the literature, very less is known about those with bilateral limb loss. Aim: To examine the gait characteristics of an individual with bilateral transtibial amputation (BTA) and its comparison with an able-bodied (AB). This study also provides a real-life presentation of successful prosthetic rehabilitation. Case content and methodology: Temporal–spatial, kinematic and kinetic gait parameters were analysed for a 45-year-old male individual with traumatic BTA using prosthesis in a motion analysis laboratory setting with force platform (BTS P-6000) and cameras with reflective markers (BTS SMART-DX6000). Findings and conclusion: Variances in many temporal–spatial, kinematic and kinetic parameters were observed. The findings of temporal–spatial parameters revealed that the individual with BTA walked with slower speed, lower cadence, shorter step lengths and wider step width compared to that of AB. Ankle dorsiflexion, stance knee flexion and swing hip hiking were reduced in an individual with BTA compared to AB. In kinetics, he demonstrated low peak ankle muscle power, increased muscle power amplitudes and phase duration at the hip and knee joints compared to AB individual. The combination of an intensive prosthetic rehabilitation led to completely independent and remarkable degree of functional ambulation.

Abstract:

The effect of unilateral and bilateral bone-filling mesh containers (BFC) on osteoporotic vertebral compression fracture (OVCF) was analyzed by the finite element method. The CT scan data of the T12-L2 vertebral body were obtained from a healthy female volunteer with no history of lumbar spine injury or obvious abnormality of vertebral body morphology. The normal finite element model of the T12-L2 vertebral body and the finite element model of osteoporosis were established, and the models were validated. The L1 in the normal model of the vertebral body was used to simulate the vertebral compression fracture, after which the unilateral and bilateral BFC were simulated to establish models representing the two surgical approaches. We analyzed changes in the deformation and von Mises stress in vertebral bodies and intervertebral discs in the two models under seven working conditions (axial direction, anteflexion, rear protraction, left-side bending, right-side bending, left rotation, and right rotation) and found that the unilateral and bilateral approaches are biomechanically comparable, with no statistical difference between the two overall models.
