Testo completoAbstract (sommario):
Cystic lesions of the maxillary sinuses include cysts, polyps and neoplasms. Maxillary sinus cysts are benign lesions that are commonly an incidental finding during X–ray, since any symptoms do not accompany their presence. An urgent problem is the development of differential diagnostics, the determination of indications for surgical treatment and the optimal treatment tactics for patients with cystic lesions of the maxillary sinuses. The authors describe their experience in patient management with maxillary sinus cysts. 175 patients (mean age — 44.93 years) with lesions in the maxillary sinus were examined and surgically operated. All patients underwent a comprehensive clinical examination aimed at a differential diagnosis of maxillary sinus pathology: cysts, polyps and neoplasms. All patients underwent endoscopic endonasal surgery: in 135 cases it was conducted via the inferior nasal meatus, in 40 patients — via the middle nasal meatus due to the large size of the cyst. Histology confirmed the established diagnosis during the clinical and instrumental examination. The postoperative period proceeded with no abnormalities. After 6 months, the patients underwent a control computed tomography of paranasal sinuses. In all cases, there was a complete cyst removal and restoration of sinus pneumatization. Thus, the differential diagnosis concerning cystic lesions of the maxillary sinus should be based on clinical manifestations and the results of X-ray techniques and follow-up of patients with scanty symptoms and signs. The optimal treatment method of maxillary sinus cysts is the endoscopic endonasal approach, followed by morphological examination. KEYWORDS: benign lesion, maxillary sinus cyst, cystic lesion, differential diagnosis, endoscopy, endoscopic endonasal approach.

Odontogenic infections can directly trigger maxillary sinusitis. CBCT is an excellent choice for precise examination of maxillary sinuses and hard tissues within the oral cavity. The objective of this retrospective and the cross-sectional study was to analyze the influence of odontogenic conditions on the presence and intensity of maxillary sinus mucous membrane thickening using CBCT imaging. Moreover, periodontal bone loss and anatomic relationship between adjacent teeth and maxillary sinuses were assessed to evaluate its possible impact on creating maxillary thickening. The study sample consisted of 200 maxillary sinuses of 100 patients visible on CBCT examination with a field of view of 13 cm × 15 cm. The presented study revealed a significant influence of periapical lesions, inappropriate endodontic treatment, severe caries, and extracted teeth on the presence of increased thickening of maxillary sinus mucous membrane. In addition, an increase in the distance between root apices and maxillary sinus floor triggered a significant reduction of maxillary sinus mucous membrane thickening. The presence of periodontal bone loss significantly increases maxillary sinus mucous membrane thickening.

Background/Aim. Mucocele of a paranasal sinus is a benign non-neoplastic condition characterized by cystic expansion and distension of the sinus cavity by retained mucoid secretions. Etiology is unknown. The purpose of this study was to estimate the efficiency of the endoscopic middle meatal antrostomy (MMA) as a treatment modality in patients with maxillary sinus mucoceles. Methods. This retrospective study involved 11 patients with maxillary sinus mucoceles/pyoceles treated endoscopically in the Clinic for Otorhinolaryngology of Military Medical Academy, Belgrade over a 3-year period (2005-2007). The presented symptoms and signs, radiological and pathohistological findings and surgical treatment were reviewed. Results. There were four females and seven males, age 22 to 65 years (mean 33 years). Two patients were with allergic rhinitis. All the patients complained of nasal obstruction, ten had facial pain, seven had nasal discharge, five had cheek pressure, and four had epiphora, and four had headaches. On endoscopic nasal examination, the medial wall of the maxillary sinus was bulging in ten patients. Purulent drainage was seen in eight patients, septal deviation in ten, and polyps were found in two of the patients. The MMA and marsupialization of the mucocele were performed in all the patients. On histopathological examination, the mucocele wall showed a lining composed of respiratory epithelium. Postoperative follow-up ranged between 8 and 44 months (in six patients, it ranged from 24 to 44 months). No patients required revision surgery. Conclusion. The MMA with mucocele marsupialization abolishes middle meatal obstruction and establishes better drainage and ventilation of the maxillary sinus and restitution of its mucosa.

Background: The purpose of the study was to analyze the efficacy of platelet-rich fibrin (PRF) as a single augmentation material for complicated cases of maxillary sinus floor elevation, resulting from membrane perforation or previous infections. Methods: Implant insertion in the posterior region of the maxilla was simultaneously performed with maxillary sinus floor augmentation. Schneiderian membrane elevation can be accompanied by extremely serious sinus membrane perforation, due to accidental tearing or intended incision for mucocele removal. PRFs were placed in the sinus cavity both for membrane sealing and sinus floor grafting. Radiological, histological and micro-CT analyses were performed. Implant survival was assessed every 6 months for 1 to 4 years, with a mean follow up of 1.8 years, after prosthetic loading. Radiological examinations were performed on CBCT at 9 and 12 and 36 months postoperatively and revealed improved degrees of radiopacity. Results: 19 implants were simultaneously placed in the course of nine maxillary sinus floor augmentation surgeries, with successful outcomes in terms of bone grafting and implant integration. New bone formation was evidenced 12 months postoperatively on radiological examination, micro-CT analysis, and histological analysis of a harvested bone segment from the augmented maxillary sinus. The mean gain in bone height of the sinus floor augmentation was 6.43 mm, with a maximum of 9 mm. The mean amount of vital bone obtained from histologic assessment was 52.30%, while bone volume/tissue volume ratio in micro-CT 3D had a mean of 50.32%. Conclusions: PRF may be considered as an alternative treatment for a single surgery of sinus augmentation with simultaneous implant placement, even in complicated cases with significant sinus membrane tearing.

Cholesterol granuloma (CG) is a foreign body reaction to the deposition of cholesterol crystals, usually found in association to chronic middle ear diseases, being highly uncommon in the paranasal sinuses. This article reports a case of CG in the maxillary sinus of a 22-year-old man, manifesting as a swelling on the right maxilla associated with pain and nasal obstruction. Computed tomography (CT) imaging showed complete opacification of the right maxillary sinus with cortical bone expansion and destruction. Incisional biopsy showed a solid mass filling the sinus and histological examination showed foreign body reaction to cholesterol crystals. The microscopic findings associated to tooth vitality, CT images and absence of a cavity during the surgical procedure were compatible with the diagnosis of CG of the maxillary sinus. Complete surgical excision of the mass under general anesthesia was suggested, but the patient did not return to conclude the treatment. CG must be included in differential diagnosis of diseases that cause opacification on the paranasal sinuses, especially sinusitis, and cystic and tumoral lesions.

Testo completoAbstract (sommario):
The purpose of this report was to analyse surgical methods for treatment of maxillary ameloblastoma and present three cases from our clinical practice in the postoperative period from 1,5 to 3,5 years. We present three patients with maxillary ameloblastoma with different etiology - two male patients and one female child. The location of ameloblastoma next to the maxillary sinus and nasal cavity indicates long-term and asymptomatic growth and comprises difficulties in clinical and X - ray examination. Ameloblastomas in posterior maxilla are very aggressive, more rapidly penetrate adjacent tissues and treatment must be radical. Subtotal resection of maxilla was carried out in all three patients, because this surgical method successfully eradicates tumor and minimizes the possibility for recurrences.

Abstract BACKGORUND. Sinus floor elevation, also known as sinus lift, is the surgical procedure meant to elevate the maxillary floor in order to increase the height of the alveolar bone. This will allow the oral surgeon specialist to insert the desired implants, the ground of dental reconstruction. As the procedure involves the maxillary sinus and its Schneiderian membrane the main concern is to have a healthy maxillary sinus prior to implantation and to the maxillary augmentation. OBJECTIVE. The aim of our study was to identify the patients with abnormal CT scan and refer them to an ENT evaluation, in order to identify and treat any sinusal pathology that can lead to a poor outcome of the sinus-lift intervention. MATERIAL AND METHODS. Our prospective study included 15 patients selected from a group of 79 adults, candidates for dental implantation with sinus augmentation. These patients had abnormal sinus CT scan in terms of mucosal hypertrophy, cysts or fungal material. Transnasal diameatic sinusoscopy was performed for all the patients, assessing the aspect of the sinus cavity and the mucosa. The following abnormal aspects were found in our group: 5 patients with cysts, 2 patients with fungus ball and 4 with mucosal hypertrophy. 4 patients had normal maxillary mucosa despite the CT scan appearance. RESULTS. All the patients with abnormal aspects at sinusoscopy (11 patients) were operated on before sinus lift procedure - antrostomy, cyst removal, fungus ball removal. 4 patients showed normal aspect of the sinus mucosa despite the CT scan donations, meaning a 26.66% error rate in appreciating the real changes of the maxillary mucosa on the CT scan. CONCLUSION. Endoscopic assessment of the maxillary sinus is mandatory in patients with changes of the CT scan. This allows a proper examination of the sinus mucosa and can predict the outcomes of the sinus lift procedures. It is mandatory to cure the inflammation or infection of the maxillary sinus prior to implant procedure in order to be able to increase the success rate, as it can lead to failures of the implant procedure.

Calcifying epithelial odontogenic tumor (CEOT) is a rare benign neoplasm, with slow, localized, invasive, and asymptomatic growth. The involvement of the maxillary sinus by the neoplasm is rare, with its treatment controversial. The aim of this study was to describe the clinical, imaging, and therapeutic characteristics of a CEOT with maxillary sinus extension, as well as a literature review of therapeutic approaches and the prognoses obtained from cases of the same extension. In this case report, we report the case of a female patient, 49 years old, Caucasian, with mild asymmetry of the middle third of the face. Clinical and imaging examinations showed an intraosseous tumor in the posterior region of the left hemimaxillary, with imprecise limits and extension of 44×24×32 mm, compromising the alveolar process, maxillary posterior teeth, posterior hemipalatal region, left maxillary sinus, and orbital floor, associated with local expansion, tooth mobility, maxillary sinusopathy, and nasal obstruction. Calcifying epithelial odontogenic tumor diagnosis was obtained from incisional biopsy and histopathological examination. Surgical therapy of partial maxillectomy was performed from the Weber Ferguson Access with subsequent prosthetic rehabilitation. There were no postoperative complications. This case presented had satisfactory success with the therapy performed. The use of invasive therapies such as partial maxillectomies associated with transfacial approaches is an effective treatment for CEOT involving the maxillary sinus. Long-term follow-up is essential to avoid recurrences.

Maxillary sinus mucocele is a benign cyst formation that originates within the sinus and is lined by epithelium containing mucus. It’s a rare pathology characterized by a clinical polymorphism. This study reports the case of a giant left maxillary sinus mucocele in a 61-year-old female patient. Through clinical examination, vestibular deformation from tooth 23 to tooth 26 was determined, and also an exophthalmos. Facial CT scan showed a cystic mass of the left maxillary sinus with bone thinning. The treatment consisted in the excision of the mucocele pocket through Caldwell-Luc approach under general anesthesia.

Testo completoAbstract (sommario):
Maxillary sinus floor augmentation is considered to play a critical role in dental implant treatment. Although many complications, such as maxillary sinusitis and infection, are well known, few reports are available on the risk of surgical ciliated cyst following the procedure. Here, we report a case of surgical ciliated cyst following maxillary sinus floor augmentation. A 55-year-old Japanese woman was referred to our hospital because of alveolar bone atrophy in the bilateral maxilla. We performed bilateral maxillary sinus floor augmentation by the lateral window technique without covering the window. The Schneiderian membrane did not perforate during the operation. She returned to our hospital after 9 years due to swelling of the left buccal region. Computerized tomography revealed a well-defined radiolucent area with radiodense border intraosseously localized in the left maxilla. We performed enucleation of the cyst with the patient under general anesthesia. Histological examination of the specimen showed a surgical ciliated cyst. In conclusion, the course of this patient has 2 important implications. First, the sinus membrane entrapped in the grafted bone without visible perforation and or tearing can develop into a surgical ciliated cyst. Second, there is a possibility that covering the lateral window tightly might prevent the development of a surgical ciliated cyst.

Sammanfattning Syfte: Syftet med denna systematiska litteraturöversikt var att testa hypotesen att det inte är någon skillnad rörande lyckandefrekvensen gällande implantatbehandling vid sinuslyft med olika bentransplantatmaterial Material och metod: Studien baseras på sökningar i PubMed, Cochrane Library och Web of Science i kombination med en manuell granskning av relevanta publikationer. Inkluderade publikationer var prospektiva studier av ≥ 10 patienter och med en uppföljningstid på ≥ 1 år. Autologt bentransplantat från mandibel/maxilla, oorganiskt ben (Bio-Oss), en kombination av dessa två samt sinuslyft utan insättning av bentransplant utvärderades. Kvaliteten på varje publikation bedömas enligt kriterier baserade på en modifiering av STROBE-statment. Resultat: Sökningen resulterade i 818 titlar och 15 inkluderade publikationer relevanta enligt förutbestämda inklusionskriterier. En studie var en randomiserad kontrollerad studie (RCT) och en var en kontrollerad klinisk studie (CCT). De återstående 13 studierna var observationsstudier. Uppföljningen varierade mellan ett och nio år, och antalet patienter mellan 10 och 191. Sinuslyft utan insättning av bentransplantat hade en implantatöverlevnad på 97,7% -100% och studier rörande autologt bentransplantat 98,8%. Bio-Oss resulterade i 86,3% -98,1% överlevnad och en kombination av Bio-Oss och autologt ben resulterade i en överlevnad på 90,7%. Slutsats: Enligt denna undersökning fanns ingen skillnad i implantat överlevnad mellan de olika bentransplantaten. Beroende på studiernas karaktär behövs fler RCT och CCT studier, som analyserar implantatutfallet, involverar sinuslyft och olika bentransplantat rörande implantatöverlevnad och lyckandefrekvens.AbstractAims: The objective was to test the hypothesis that there is no difference in implant treatment outcome using different bone graft material for sinus floor augmentation.Material and methods: This systematic review is based on searches in PubMed, the Cochrane Library and the Web of Science and a hand search of relevant publications. Autologous bone, anorganic bovine bone (Bio-Oss), a combination of these two and elevation of the Schneiderian membrane with no graft material was evaluated. The quality of each publication was assessed according to criteria based on the STROBE-statements.Results: The search provided 818 titles and 15 were found relevant according to the predetermined inclusion criteria. One study was a randomized controlled trial (RCT) and one was a controlled clinical trial (CCT). The remaining 13 studies were observation studies. The follow-up time varied between one and nine years and the number of patients between 10 and 191. Studies on elevation of the Schneiderian membrane with no bone graft material reported an implant survival rate between 97.7% and100% and studies on only autologous bone graft material 98.8%. Bio-Oss as bone graft material resulted in 86.3%-98.1% survival rate and a combination of Bio-Oss and autologous bone graft resulted in a survival rate of 90.7%.Conclusion: There was no difference in implant outcome of the different bone graft material. More studies designed as RCT and CCT, which analyze the implant outcome involving sinus floor augmentation and different bone graft material are needed to improve evidence on survival and success rate.

Testo completoAbstract (sommario):
This study characterized maxillary sinus mucositis (SIMS) adjacent to teeth with apical periodontitis (AP), and assessed its resolution three months after endodontic treatment. 29 subjects who maxillary posterior teeth with AP were imaged with cone-beam computed tomography (CBCT). Resolution of SIMS was assessed with CBCT three months after treatment, and periapical healing was assessed using the PAI after six months. Four non-compliant subjects were discontinued and SIMS was identified in 14/25 subjects (56%). Three months post-treatment, SIMS was resolved fully in 3/10 subjects (30%), and partially in 3/10 subjects (30%). Six months post-treatment, 6/10 subjects (60%) were classified as healed or healing. CBCT revealed a lower-than-expected prevalence of SIMS adjacent to teeth with AP. In specific cases SIMS might linger beyond three months after the elimination of the endodontic infection. Due to the low statistical power, association between the resolution of SIMS and periapical healing could not be explored.

Testo completoAbstract (sommario):
Cushing’s syndrome is a descriptive term of a syndrome secondary to elevated levels of steroids or cortisol, while Cushing’s disease is hypercortisolemia that results from an adrenocorticotropic (ACTH)-secreting pituitary adenoma. Patients will present with cushingoid features on physical examination and can be myopathic with proximal rather than distal muscle weakness. Diagnosis can be obtained by multiple avenues including but not limited to checking 24 hour urine cortisol, a dexamethasone suppression test, checking ACTH levels, a CRH (corticotrophin-releasing hormone) stimulation test, and inferior petrosal sinus sampling (IPSS). Once Cushing’s disease is confirmed, treatment is via transsphenoidal resection of the pituitary adenoma.

Testo completoAbstract (sommario):
Bradyarrhythmias (defined as a heart rate <60 beat/min) occur frequently in the critical care setting. Most are related to underlying disease processes and the multidrug therapies administered. Because of the intense monitoring of these patients, recognition is generally easy. Examination of the ECG will allow diagnosis of the type of bradycardia based on the sinus node, atrioventricular node and the infra-Hissian conducting system. The extent of conduction system disease can be estimated and this has an influence on the prognosis. Bradycardias causing haemodynamic collapse require treatment of underlying causes, resuscitation, and administration of atropine and epinephrine. If there is no response to these then either transcutaneous pacing, or temporary transvenous pacing is necessary. This can be followed by implantation of a permanent pacing system. The outcome of correctly diagnosing and treating a bradyarrhythmia is excellent as long as the causative pathology can be stabilized.

Testo completoAbstract (sommario):
Antrochoanal polyp (ACP) is a benign unilateral polyp, originating from the maxillary sinus and expanding through the accessory or natural ostia into the nasal cavity and choanae. It has a 2: 1 male predominance and is more common in children and young adults. The exact pathophysiology is unclear, and it is thought to have less of the inflammatory reactions as opposed to typical bilateral nasal polyps which are commonly seen in diffused chronic rhinosinusitis. The presenting symptoms of ACP are unilateral nasal obstruction and rhinitis. Epistaxis, pain, and foul-smelling secretions are not typically seen and point towards a different etiology. Diagnosis is mainly clinical via endoscopic examination and supported by Computed tomography (CT) imaging. In CT images the three components of the polyp can be identified; an intramaxillary portion, intranasal and choanal components. Treatment is surgical, where Endoscopic sinus surgery (ESS) is the main technique used with other assisting approaches to reach the more challenging anterior and inferior areas of the maxillary sinus. Successful resection depends on complete removal of the intramaxillary component of the polyp to avoid polyp regrowth. The typical histologic characteristics are cyst formation, fibrosis and squamous metaplasia that are significantly more common in ACP than diffused nasal polyps.

Testo completoAbstract (sommario):
Oral and maxillofacial surgical procedures, such as tooth extractions, surgical treatment of odontogenic maxillary sinus pathologies, dental implant surgery, orthognathic surgery, and sinus lift procedures, often correlate with the maxillary sinuses, due to anatomical proximity. For instance, in Le Fort I osteotomy, which is the predominant surgical technique preferred for the treatment of dentofacial deformities of the maxilla, the osteotomy line includes maxillary sinus and nasal walls. Maxillary sinus-lifting surgery is performed to regenerate bone in the posterior maxilla for dental implant placement. Additionally, maxillary sinus pathologies of odontogenic origin, such as sinusitis, cysts, and neoplasms, can impact the oral and maxillofacial region, and surgical intervention may be required to manage these conditions. Proper diagnosis, treatment planning, and surgical techniques are essential to optimize patient outcomes and minimize complications related to the maxillary sinuses in oral and maxillofacial surgical procedures.

Testo completoAbstract (sommario):
Dental implants have significantly increased prosthetic options for the edentulous patient. Implant placement in the posterior maxilla may often be hampered due to anatomical limitations, inadequate height and width, and poor bone quality. After tooth extraction, three-dimensional physiological resorption and sinus expansion take place and reduce the volume of the alveolar ridge. The concomitant actions of alveolar atrophy and sinus pneumatization reconstruct the subantral alveolar segment into a low, shallow, and sloped ridge which is incapable to accommodate dental implants and bear the functional strains. Advanced maxillary resorption can be managed by several surgical options, the most popular of which is maxillary sinus floor elevation. The chapter discusses recent advancements in bone biology and biomechanics in the light of alveolar atrophy and the impact of anatomy on maxillary sinus floor elevation as a treatment modality for the partially or totally edentulous patient.

Testo completoAbstract (sommario):
The development of modern surgical methods and techniques for treatment of the diseases of the paranasal sinuses and the edentulous ridge of the maxilla requires detailed knowledge of the anatomy, physiology and pathology of the maxillary sinus. The sinus dimensions and volume, thickness of the mucosa, height of the inferior wall and presence of septa and root prominence are important indicators for the pneumatization of the maxillary sinus and have essential role by performing sino-nasal and dental implant surgery. The preliminary assessment of some morphological aspects of the maxillary sinus is essential for the proper diagnosis and treatment of a number of diseases in maxillofacial region, including treatment of the chronic rhinosinusitis and the edentulous ridges of the distal maxilla.

Testo completoAbstract (sommario):
Introduction: Tolosa Hunt syndrome (THS) is a rare condition, incidence of 1/1.000.000 case per year, characterized by unilateral painful ophthalmoparesis caused by idiopathic inflammation in the cavernous sinus. The oculomotor nerve is most commonly involved (80%), followed by abducens nerve (70%), ophthalmic branch of trigeminal nerve (30%), trochlear nerve (29%). Case presentation: Male, 77 years old, admitted with an acute moderate-intensity orbitofrontal headache on the left, envolving with palpebral ptosis of the left eye. Neurological examination: complete palpebral ptosis on the left and ophthalmoplegia of the entire ipsilateral extrinsic ocular musculature. A complete investigation was carried out: metabolic, rheumatological, serological tests without significant alterations and study of the cerebrospinal fluid with mild hyperproteinorachia, without pleocytosis. Magnetic resonance imaging (MRI) of the skull showed thickening of the cavernous sinus on the left, with contrast enhancement; Angio-MRI of the Skull and Neck without alterations. Therefore, THS was diagnosed and treatment with Methylprednisolone 1 g for five days, with complete improvement of headache and partial improvement of ophthalmoparesis. The patient was discharged with 60 mg of prednisone orally with instructions for gradual weaning off, return to the neurology outpatient clinic. Discussion: THS diagnosis is based on the International Classification of Headache Disorders: unilateral periorbital headache; granulomatous inflammation of the cavernous sinus, superior orbital fissure or orbit on cranial MRI; paralysis of one or more of the oculomotor nerves; the headache must precede the ophthalmoparesis by up to two weeks or appear concomitantly. The exclusion of secondary causes is essential. Treatment of choice is cortico steroids, improvement of headache in the first days, and of ophthalmoparesis in 2–8 weeks. Conclusion: Unilateral headache with ipsilateral ophthalmoparesis should raise the suspicion of THS.

Context: Brain venous thrombosis (BVT) is uncommon and usually has a different clinic and treatment from cerebral arterial thrombosis. In this context, COVID-19 correlates with thrombogenesis with varied clinical repercussions. This report describes an unusual BVT case as a possible late complication of COVID-19. Case report: Male, 68 years old, athlete and healthy. April/2020: COVID-19 mild symptoms. February/2021: in road-running, he fell due to sudden left hemiparesis. Upon hospital admission: contacting, persistent headache. A week after, low level of consciousness and coma, when underwent right hemicraniectomy. Remains hospitalized. On examination: weak gestural communication, tracheostomy, enteral tube feeding, voluntary blinking. Maintains neutral cervical posture, masticatory automatisms, photoreactive isocoria, generalized rigidity, decorticated right hemiparesis, left hemiplegia. On imaging: hemorrhagic infarction on the right and mass effect due to obstruction of the Basal Rosenthal and Labbé veins and transverse sinus on the right, with venous blood flow in the rest of the hemisphere diverted to the ipsilateral internal jugular vein, by anastomotic veins of the occipital foramen and suboccipital venous plexus. Obstructed left internal jugular vein, with venous collateral flow from the left hemisphere via posterior intercavernous sinus and basilar plexus to the right internal jugular vein. Conclusions: To diagnose the venous etiology that resembled segmental occlusion of the right middle cerebral artery, CT angiography was required. Late evolution of COVID-19 has been identified by the persistence of symptoms for months. Although physical activity and possible dehydration may have contributed to BVT, a prothrombotic state correlated to COVID-19 cannot be discarded.

Case presentation: A 4-year-old boy was born to non-consanguineous parents at 38 weeks. Neonatal anthropometric measurements were normal. Since birth, he presented with global developmental delay, and muscular hypotonia. At present, he shows adequate psychosocial interaction. He has a healthy 3-year-old sister. On physical examination, there are dysmorphisms, such as prominent and pointed ears, long eyelashes, elongated face, flat occipital region, supernumerary teeth, and maxillary hypoplasia. His anthropometric measurements are normal for his age (p50). On neurological examination, he presents with apraxia of speech, axial and appendicular hypotonia, and reduced deep tendon reflexes. Brain magnetic resonance imaging showed a slight thinning of the corpus callosum and mild ectasia of the lateral ventricles. Transthoracic echocardiography and ultrasound of the kidneys and urinary tract were normal. On genetic investigation, no abnormalities were found in karyotype and CGH-Array. Whole exome sequencing showed a pathogenic variant in the PUF60 gene (c.24+1G>C) in heterozygosis. Thus, the patient was diagnosed with Verheij syndrome. The patient is accompanied by physiotherapy, speech therapy, occupational therapy, and a psychopedagogy group. Discussion: Verheij syndrome is a rare condition caused by variants in the PUF60 gene, which encodes a component of the spliceosome. This syndrome is characterized by intellectual disability, delayed growth and neuropsychomotor development, facial dysmorphic features, and osteoarticular abnormalities. Also, there may be heart and kidney disorders. The spectrum of this disease’s manifestations and severity still need to be further explored in future studies, as well as the treatment and prognosis of this condition. Multidisciplinary support is essential for managing the consequences of the disease. This case report reinforces the leveraged importance that genetics has had in the diagnosis of intellectual disabilities.

Background: Germ cell malignancies account for about 5% of all ovarian cancers. These tumours grow rapidly and often produce symptoms quicker than the slow growing epithelial tumour. Commonly seen in the first two decades of life germ cell malignancies are highly chemosensitive and are potentially curable with surgery and chemotherapy. This study is the first of its kind regarding the epidemiology, management and outcome of patients with malignant germ cell tumour in Nepal. Objective: To analyze the clinical presentation and management outcomes of malignant germ cell tumours managed in B.P. Koirala Memorial Cancer Hospital, Nepal. Methodology: Descriptive study conducted in B.P. Koirala Memorial Cancer Hospital, Nepal. Case records of malignant germ cell tumours attending the hospital from January 1999 to December 2009 were analyzed regarding their illness history, clinical examination, investigations, treatment, follow-up and outcomes measured. Observations: Total 65 cases of malignant germ cell tumours with age range from 2 to 58 years (mean 21.7 years) were received. 42% cases were Tibeto-Burmese; 30% were Indo-Aryans. There were 15 cases (23%) of dysgeminoma, 21 endodermal sinus tumor (32%), 16 Immature Cystic Teratoma (24.5%), 9 (14%) Mixed Germ Cell, 2 unclassified GCT (3.5%) and 2 malignant transformation in teratoma (3.5%). 33 (49.5%) patients had early stage disease, 37 (57%) underwent fertility preserving surgery. 4 cases (9%) due to disseminated disease, underwent neoadjuvant chemotherapy followed by debulking surgery. 51 cases (78.5%) received adjuvant chemotherapy (BEP or EP regimen). The overall survival was 70%. Conclusion: Early stage germ cell malignancies can be safely managed by fertility preserving surgery followed by, chemotherapy if indicated. For advanced diseases, neoadjuvant chemotherapy followed by surgery can be undertaken with curable intent.

Testo completoAbstract (sommario):
Li-Fraumeni syndrome is a disease with an autosomal dominant inheritance of high penetrance and was originally described in 1969. The definitive diagnosis is based on the identification of a pathogenic variant in the TP53 gene. Birch and Chompret and classical models were used as the clinical criteria to identify individuals who are the candidates for molecular screening. It is responsible for about 1% of hereditary breast cancers and is related to other neoplasms, the most common sarcomas, leukemias, and adrenal carcinoma. Among the differential diagnoses, we can consider pathogenic variants of BRCA1/BRCA2 and Lynch syndrome. The behavior of cancer is usually similar to that of patients without Li-Fraumeni syndrome except for the age of early onset. Screening for the breast cancer with an annual magnetic resonance is recommended in women from the age of 20, colon cancer with colonoscopy every 2 or 5 years from the age of 25, and osteosarcoma and soft-tissue tumor with full-body resonance at an early age. Interventions are recommended for patients with a family history or individuals with a reported mutation. Mastectomy is generally recommended for women with breast cancer due to the risks of a second primary breast cancer or a second radiation-induced cancer. The risk of contralateral breast cancer in patients with TP53 diagnosed under 35 years of age is approximately 4%–7% per year. In this scenario, we bring a case report of a young female patient with synchronous tumors of maxillary osteosarcoma and breast cancer to study the approach, prevention, and guidance in these cases. N.O.B., 21 years old, single, born in São Paulo, nonparturient, mother’s death due to breast cancer at age 36, and sister’s death due to neuroblastoma at age 2. At the first medical appointment in June 2021, she complained of the presence of a nodule in her left breast persisting for 2 years and reported a palate lesion present for 1 month and with rapid growth, associated with existing oral cavity deformity. On the breast ultrasound examination performed in June 2021, a solid, hypoechogenic, irregular, microlobulated, nonparallel to skin was revealed, measuring 1.5×1.2×1.3 cm at 10 h of the left breast (BI-RADS classification®: 5). The pathological report from a directed biopsy of the nodule showed an invasive carcinoma of nonspecial histological type, estrogen receptor 80%, progesterone receptor 100%, Her2 negative, and Ki67 60% — clinical staging cT1N0. The examination of her palate lesions reported high histological osteosarcoma — cT1N0M0. Considering the double-tumor diagnosis plus the highly aggressive lesion of the patient’s palate, the team chooses to start the treatment with partial maxillectomy and bilateral infrastructure surgery, tracheostomy, and reconstruction with a microsurgical flap of the right fibula in July 2021. Later in October 2021, the patient’s treatment was followed by a combination of left adenomastectomy, left sentinel lymph node biopsy, and reconstruction with bilateral prosthesis. Due to family and personal history, she went through genetic testing for pathogenic mutation on the TP53 gene. Fertility preservation was performed with oocyte freezing. As an adjuvant treatment, it is scheduled for four cycles of docetaxel and cyclophosphamide. As prophylactic measures, the patient is expected for an adenectomy in the contralateral breast and to follow up with clinical examinations twice a year, as well as both mammography and MRI once a year.

"Hypertrophic pachymeningitis associated with systemic lupus erythematosus: a case report". In XIV Congresso Paulista de Neurologia.

Testo completoAbstract (sommario):
Introduction: Hypertrophic pachymeningitis is a chronic inflammatory process that results in focal or diffuse thickening of the dura mater. Nowadays, it’s an uncommon cause of neurological symptoms and has been mainly associated with infections, inflammatory diseases and carcinomatosis. This is a report of a single case based on retrospective analysis of the patient’s medical records. Case report: A 48-year-old woman was admitted in the emergency department with a two-month history of severe headaches that worsened with neck flexion and four episodes of focal to bilateral tonic-clonic seizures. In addition to that, she also complained of intermittent gritty sensation and redness in both eyes and arthritis of the hand and wrist joints. Her past medical history included systemic lupus erythematosus, bilateral lower limb deep venous thrombosis and cerebral venous thrombosis (CVT). She was on anticoagulant therapy with rivaroxaban 20 mg daily at the time. On admission, patient presented with bilateral conjunctival hyperemia and slit-lamp examination showed mild anterior chamber flare reaction (grade of 2+). Neurologic examination revealed impaired attention and nuchal rigidity. Brain magnetic resonance imaging was performed and showed linear dural thickening and diffuse pachymeningeal post-contrast enhancement over cerebral convexities, falx cerebri and cerebellar tentorium, with hyperintense signal on T2- weighted sequence in the subcortical region of the right frontal lobes, which might have resulted from obstruction of venous reflux caused by previous CVT. Brain venogram demonstrated partial recanalization of superior sagittal sinus. Lumbar puncture revealed a clear cerebrospinal fluid (CSF) with 12 cells/ mm3 (82% lymphocytes, 13% monocytes, 5% plasmocytes), total protein of 46 mg/dL and glucose of 58 mg/dL. Search for infectious agents by microscopy, culture and molecular testing resulted negative. Systemic investigation was negative for infections or metabolic dysfunction, but it revealed elevated inflammatory markers and hypocomplementemia. Her panel of autoantibodies revealed an ANA titer of 1:640 with a nuclear homogeneous pattern and was negative for the others (anti-dsDNA, anti-Sm, anti-RO, anti-LA, anti-RNP, RF). The patient was then treated with intravenous methylprednisolone 1 g daily for five days and followed by maintenance treatment with oral prednisone 60 mg daily. She showed good improvement of symptoms, as well as a significant reduction of CSF leucocytes and protein content. Unfortunately, it was not possible to obtain a meningeal biopsy at the time. The patient was finally discharged from the hospital and, given the rare association between pachymeningitis and SLE, is expected to return for a follow-up consultation with neurology for additional investigation. Conclusion: Although hypertrophic pachymeningitis has been related with some autoimmune disorders, it is an extremely rare form of nervous system manifestation in SLE. Despite the plausible relationship between the patient’s SLE disease activity and hypertrophic pachymeningitis, further investigation is still required to rule out other etiologies. Nevertheless, we hope our report will raise awareness of hypertrophic pachymeningitis as a possible differential diagnosis in SLE patients with new-onset headache with nuchal rigidity.
