Résumé :

Introduction: The liver possesses different patterns of intrahepatic duct confluences. Even though the typical pattern of the intrahepatic biliary duct is common, atypical variations are also frequently witnessed. The knowledge of the atypical intrahepatic biliary confluences is inevitable during hepato-biliary surgery to reduce post-operative complications. The aim of the study was to find out the prevalence of the atypical pattern of intrahepatic biliary duct pattern on magnetic resonanace cholangiopancreatography in a tertiary care centre. Methods: This descriptive cross-sectional study was done in a tertiary care centre after receiveing ethical approval from the Institutional Review Committee [Reference number: KUSMS/IRC (248/2021)]. The branching patterns of the atypical intrahepatic biliary pattern were observed in Magnetic resonance cholangiopancreatography images and were classified. Convenience sampling was used. Point estimate and 95% Confidence Interval were calculated. Results: Among 199 magnetic resonance cholangiopancreatography images, the atypical intrahepatic biliary duct was observed in 48 (24.12%) (18.18-30.06, 95% Confidence Interval) of the images. Conclusions: The prevalence of the atypical intrahepatic biliary duct pattern is lower as compared to other studies done in similar settings.

Résumé :

Background/Aims: Endoscopic submucosal dissection (ESD) for gastric neoplasms is a widely performed procedure. Local recurrence is rare, but various post-ESD scars are encountered during follow-up endoscopy. Therefore, we investigated atypical scar patterns and evaluated the associated factors.Materials and Methods: Clinicopathologic and endoscopic reviews of gastric neoplasms treated with ESD from January 2009 to December 2015 were conducted. Atypical scar patterns were classified as irregular erythema, nodularity, or mucosal defect.Results: A total of 264 patients with 274 gastric neoplasms, including 201 adenomas and 73 early gastric cancers, were enrolled. The key endoscopic findings at the resection scar were defined on the basis of gross morphology as follows: irregular erythema, mucosal defect (erosion or ulcer), and nodularity. An irregular erythema scar pattern was associated with male sex, a nodularity scar pattern with smoking, and a mucosal defect scar pattern with infra-angle location (angle and antrum) and cancer. An irregular erythema with nodularity scar pattern was also associated with male sex. An irregular erythema with nodularity and mucosal defect scar pattern was associated with liver disease and chronic kidney disease.Conclusions: The atypical scar patterns after gastric ESD are associated with various clinicopathologic factors.

Résumé :

9077 Background: We investigated case reports of nivolumab-induced ILD in patients with non-small cell lung cancer to identify risk factors for poor prognosis of ILD. Methods: Among data obtained during post-marketing surveillance of nivolumab, case reports of ILD with detailed clinical course and chest imaging (CT) findings were assessed by the ILD Expert Review Committee, which consists of respiratory medicine specialists and expert chest radiologists. The imaging findings were examined and classified into those with typical or atypical patterns. Atypical patterns included shadows limited to surrounding tumors designated as “peritumoral infiltration”, relapse of radiation pneumonitis, worsening of underlying infection, and predominant shadow in diseased side. CT pattern was classified as DAD (diffuse alveolar damage) or non-DAD. Data were analyzed using a multivariate stepwise logistic regression analysis. Results: Among 160 reported cases of ILD, 140 cases were considered to be induced by nivolumab. Imaging findings showed typical patterns in 92 patients, and 23 (25.0%) died of ILD. Atypical patterns were noted in 48 patients, and 5 (10.4%) died of ILD. The following table summarizes the results of univariate and multivariate analyses of risk factors for poor prognosis of ILD. See table. DAD pattern was observed in 20, 14 (70%) among them showed fatal outcome, whereas non-DAD pattern showed it in 14/120 (11.7%). Male and pretreatment CRP level were significant risk factors for fatal outcome. Conclusions: Nivolumab-induced ILD may show some atypical pattern that was not seen in conventional chemotherapy or EGFR-TKI. Outcome of patients with atypical patterns was better than those with typical patterns. DAD pattern at CT, male, and pretreatment level of CRP were identified as risk factors of fatal outcome.

Résumé :

Background: Type 1 endometrial carcinoma is usually preceded by atypical hyperplasia. Nonatypical hyperplasia should be managed conservatively and atypical hyperplasia have to be managed aggressively. So, the diagnosis is crucial for its management.Methods: The study population included women diagnosed with endometrial hyperplasia by histopathology as per WHO classification 2014 from the year January 2015 to February 2020.Women with endometrial polyp diagnosed by transvaginal ultrasonography and histopathology were excluded. Primary objective was to compare the endometrial thickness between the two types of hyperplasia. Secondary objective was to analyses the risk factors of the two types.Results: In multivariate analysis of logistic regression, diabetic women have 1.57 times risk of developing atypia and obese women have 3.12 times risk of developing atypia. Polycystic ovarian disease is having borderline significance for causing atypia. There was significant difference in endometrial thickness between atypical and nonatypical hyperplasia (P=0.040). In premenopausal women, (P=0.069) the thickness difference in atypia is of only borderline significance. Heteroechoic pattern or cystic spaces in the endometrium also didn’t predict atypia.Conclusions: Mean endometrial thickness is significantly different in atypical hyperplasia. Heteroechoic pattern of endometrium do not predict atypia. We need color doppler sonography to gain knowledge about atypia. Obesity and diabetes mellitus are significant risk factors of atypia.

Résumé :

In ambito psicometrico, un tratto latente è una caratteristica non osservabile di un individuo. Per misurare tale tratto si ricorre comunemente all’uso di questionari che attraverso le risposte ad una serie di domande produce un punteggio totale indicativo di tale tratto latente. Il punto di partenza di questo lavoro è stata l’analisi di dati raccolti tra operatori sanitari di un grosso ospedale di Milano che hanno affrontato la pandemia COVID-19 e il cui benessere psicologico è stato valutato attraverso scale validate (GHQ-12, IES-r, GAD-7). In questo contesto, la Teoria Classica dei Test (TCT) e l’Item Response Theory (IRT) rappresentano le due teorie principali per analizzare in modo opportuno test basati su questionari. In psicometria l’uso della TCT è molto diffuso, mentre l’IRT sta avendo un crescente utilizzo solo recentemente. Partendo da una serie di quesiti clinici nati all’interno del contesto sanitario in cui tale lavoro è stato svolto, abbiamo analizzato preliminarmente i dati relativi a questionari di 990 operatori sanitari arruolati tra Luglio 2020 e Luglio 2021 attraverso un’analisi dei fattori di rischio per la compromissione del benessere psicologico. Abbiamo poi analizzato le scale psicometriche intendendole come strumenti di misurazione di un tratto latente. Abbiamo mostrato l’utilità e i benefici della teoria IRT applicandola ad una delle scale somministrate nei questionari, la General Health Questionnaire-12 (GHQ-12), un test ampiamente usato per valutare la salute mentale di un individuo. Attraverso l’IRT abbiamo indagato tre principali aree di interesse. Tramite la versione multidimensionale dei modelli IRR abbiamo indagato la dimensionalità, mostrando che la salute mentale degli operatori sanitari è stata affetta principalmente da due fattori misurati dalla GHQ-12, che hanno impattato in modo diverso il benessere psicologico. Da un lato è emerso un chiaro e diffuso stato di stress e preoccupazione, dall’altro molti individui hanno provato una sensazione di non avere un ruolo utile tramite proprio lavoro e di non essere in grado di prendere decisioni. Tramite l’analisi del DIF (differential item functioning) abbiamo evidenziato le differenze nelle risposte al questionario in sottogruppi: tra chi ha lavorato direttamente o indirettamente a contatto con pazienti COVID-19 e tra chi è stato arruolato prima o dopo la campagna vaccinale. Attraverso la versione di modelli IRT basata su classi latenti abbiamo mostrato come certe tipologie di risposta riescono a prevedere l’esito finale dello screening psicologico dei soggetti, che prevede in tutto tre fasi. Infine, nell’ambito della statistica robusta, abbiamo proposto un algoritmo basato sul metodo forward search per l’individuazione di risposte atipiche nei questionari e lo abbiamo testato ad un caso particolare di modelli IRT, il modello di Rasch. A latent trait is an unobservable psychological attribute of an individual. A common way to measure it relies on the use of questionnaires, which collect person’s responses to test items and calculate a score representing the underlying latent trait. We analysed data collected among health care workers (HCWs) who faced COVID-19 pandemic and whose psychological wellbeing was evaluated through psychometric scales (GHQ-12, IES-r, GAD-7). Classical test theory (CTT) and item response theory (IRT) represent two different measurement frameworks. Starting from a series of clinical questions arising from a specific medical environment, objectives of this work were to explore the clinical implication of the tests’ outcome, performed through risk factor analysis for psychological impairment on a sample of 990 HCWs, and to evaluate the structure of the scales intended as measurement tools. We provided demonstration of the utility of IRT as compared with CTT-based method through the analysis of General Health Questionnaire – 12 (GHQ-12 questionnaire), a valid and reliable tool widely used to measure mental health. IRT-based techniques enable us to delve in several areas of interest of GHQ-12 questionnaire. Through the multidimensional version of IRT models we assess its dimensionality, finding that HCWs' psychological wellbeing was affected by general discomfort and stress together with a strong feeling of uselessness and inability to make decisions. Differential item functioning (DIF) detection performed with IRT investigated possible differences in responses between subjected directly or indirectly involved with COVID-19 patients and between workers enrolled before or after vaccination campaign, showing how their psychological status was affected by such circumstances. The discrete version of IRT (based on latent class analysis) allowed to determine how some response pattern may predict individual’s outcome of psychological wellbeing evaluation which consisted in three steps. Lastly, we explored the issue of atypical response pattern detection applying Forward Search algorithm to Rasch model.

Résumé :

We report the peculiar chemical abundance patterns of 11 atypical Milky Way (MW) field red giant stars observed by the Apache Point Observatory Galactic Evolution Experiment (APOGEE). These atypical giants exhibit strong Al and N enhancements accompanied by C and Mg depletions, strikingly similar to those observed in the so-called second-generation (SG) stars of globular clusters (GCs). Remarkably, we find low Mg abundances ([Mg/Fe]. < 0.0) together with strong Al and N overabundances in the majority (5/7) of the metal-rich ([Fe/H] greater than or similar to-1.0) sample stars, which is at odds with actual observations of SG stars in Galactic GCs of similar metallicities. This chemical pattern is unique and unprecedented among MW stars, posing urgent questions about its origin. These atypical stars could be former SG stars of dissolved GCs formed with intrinsically lower abundances of Mg and enriched Al (subsequently self-polluted by massive AGB stars) or the result of exotic binary systems. We speculate that the stars Mg-deficiency as well as the orbital properties suggest that they could have an extragalactic origin. This discovery should guide future dedicated spectroscopic searches of atypical stellar chemical patterns in our Galaxy, a fundamental step forward to understanding the Galactic formation and evolution.

Résumé :

Class of 2007 Abstract Objectives: This retrospective analysis compared the prescribing rates of typical versus atypical oral antipsychotics in the treatment of schizophrenia for 6 months before versus 6 months after the publication of the Phase 1 CATIE trial on September 22, 2005. Methods: Prescription and membership databases from COPE Behavioral Services in Tucson, AZ were utilized for determining prescribing rates of typical and atypical antipsychotics for pre- versus post-publication of the CATIE trial. Comparisons were made for gender, court order treatment, hospitalizations and length of stay, costs of services (case management, inpatient, lab, and other services), total number of prescriptions and number of tablets/capsules of typical and atypical antipsychotics, and cost of antipsychotic prescriptions. Results: There was no significant difference in prescribing rates for oral atypical and typical antipsychotics, cost of services, or hospitalization rates in the pre-publication (N=316) versus post-publication (N=336) groups. Atypical antipsychotics accounted for approximately 77% of antipsychotic prescriptions and for 98% of the total costs for antipsychotic therapy in the two time periods. During the 12-month study, the amount paid for atypical antipsychotic prescriptions was $ 1,026,004 versus $ 22,671 for typical antipsychotics. Conclusions: Prescribing patterns of oral typical and atypical antipsychotics for the treatment of schizophrenia did not change during the first six months after the publication of the phase I CATIE trail in this outpatient population. Atypical antipsychotics accounted for the majority of prescriptions and for the highest cost compared to other services provided despite similar efficacy to typical antipsychotics in the treatment of schizophrenia.

Résumé :

The lyssavirus genus of the Rhabdovirus family is divided into seven genotypes. Genotype 3, Mokola virus, has only been found on the African continent, and has been reported to infect rodents, cats, dogs and humans. The first Mokola virus identification in South Africa was made in 1970, on the east coast of the KwaZulu-Natal province. After 25 years, Mokola virus was again identified in three cats, 650 km south-west of the previous isolation. In 1997 two more Mokola infections were identified in Pinetown, only about 23 km south-west of the 1970 isolation. Phylogenetic analysis of the nucleic acid sequences of the nucleoprotein gene region of the Mokola genome, indicated that the Mokola viruses from the same geographical region were more closely related, irrespective of the time of isolation. The identification of these two distinct clusters of Mokola in South Africa leads i us to believe that this virus is more widespread than previously thought, but that the reservoir host species remains to be identified. Genotype 1 in the Rhabdovirus family, rabies virus, is found on all continents, except Australia, New Zealand, Papua New Guinea, Japan, Hawaii, Taiwan, United Kingdom, Ireland, etc. An ongoing rabies enzootic in southern Africa is associated with two genetically distinct groups of viruses, called the canid biotype (infecting carnivores of the family Canidae) and the viverrid biotype (infecting carnivores of the subfamily Viverrinae). We identified the first cases of spillover of canid biotype virus into viverrid hosts, using monoclonal antibody and nucleic acid sequence analysis. Genetic analysis of the G-L intergenic region of the rabies virus genome, showed that these spillover events do not bring about any significant change on this part of the virus genome. All of these spillover isolates maintained a typical canid virus phylogeny. Rabies viruses associated with the family Viverridae form a highly diverse group of viruses, which can be divided into four distinct phylogenetic groups, each associated with a specific geographical area in South Africa. The canid biotype of rabies virus is divided into three specific groups, based on geographic location and the associated reservoir species, namely KwaZulu-Natal province (with domestic dogs as its main vector), the western parts of South Africa (bat-eared foxes) and the northern parts of South Africa (black-backed jackals). In order to determine the degree of genetic change in the virus over a period of time, we identified two endemic canid rabies regions (KwaZulu-Natal and the northern parts of South Africa) and analysed the nucleic acid sequence variation 0f the viruses over 15 years. Phylogenetic analysis of the variable G-L intergenic region of t e virus genome indicated that the canid rabies biotype changed less than 1% over the period studied. This implies that the highly diverse viverrid biotype has been circulating in the southern African wildlife for a very long time. In order to obtain a faster, more economical, and reliable method for rabies virus biotype identification, a competitive, hemi-nested PCR assay was developed. In a single tube, two biotype specific oligonucleotides (developed by Jaftha, 1997), and a common downstream primer were -used in the biotype specific, second round amplification. The specific virus biotypes were identified on the basis of specific amplicon sizes for each biotype. A third biotype specific primer was designed to target a region of the Nucleoprotein gene, this primer was used in a second round hemi-nested reaction. Despite having been designed to specifically amplify canid biotype viruses, this primer amplified all rabies biotypes non¬specifically. We conclude that the nucleoprotein genes are too conserved to make this part of the genome a good target for a biotype-specific PCR diagnostic assay.

Résumé :

碩士 國立臺灣大學 醫學檢驗暨生物技術學研究所 102 Staphylococcus aureus is a common Gram positive bacteria, and is different from other Staphylococcus species by biochemical activities such as coagulase. Staphylococcus aureus is reputed by its golden colony type, nevertheless, a lineage of non-pigmented S. aureus displaying white colonies had been found recently. Currently, the major identification method for Staphylococcus species is by biochemical tests. But, biochemical activities usually have variation. Identification by 16S rRNA sequencing is more reliable, but it would cost more money and manpower. So, dnaJ gene PCR-RFLP would be a good choise for identification of Staphylococcus species. In the beginning of this study, we found a S. aureus isolate with an atypical dnaJ gene PCR-RFLP pattern, further , we tried to study on 2 atypical S. aureus dnaJ gene PCR-RFLP patterns in NTU hospital, trying to find out its proportion and bacterial characteristics. After the atypical pattern S. aureus had been selected out, we did the sequence blast and found out that atypical pattern 1 S. aureus is very similar to non-pigmented S. aureus mentioned above. Then we did some molecular typing, and found that atypical pattern 1 S. aureus isolates belongs to clonal complex 75, and atypical pattern 2 S. aureus isolates belongs to clonal complex 45. All of these three pattern could be separated by Pulsed-field gel electrophoresis and MALDI-TOF. Atypical pattern 1 S. aureus shows similarity in dnaJ gene sequence with the lineage of non-pigmented S. aureus. By pigment gene detection and the extraction of pigment, we found that atypical pattern 1 S. aureus truly was unable to produce pigment. The golden pigment is recognized as one of important virulence factor of S. aureus, which plays a great role in reducing the oxidative stress damage and resisting netrophil phagocytosis. Though lacking of this pigment, atypical pattern 1 S. aureus still had its stand in isolates in NTU hospital. Thus this study tried to examine virulence factors and biofilm activity on 2 atypical pattern S. aureus for studying its advantage during infection. The toxin shock syndrome toxin gene was found in many atypical pattern 2 S. aureus (60.9%), and so did it in biofilm activity in atypical pattern 1 S. aureus. These results might be an explanation for the well ability of infection. We then used Vitek 2 automated system to check the biochemical activities of 2 atypical pattern S. aureus, and found a dramatic high proportion on urease activity in atypical pattern 1 S. aureus. This result was confirmed by tube biochemical test, but after testing growth curve, we found it might not enhance the growth activity even in urea broth.

Résumé :

Introduction: Une respiration buccale est souvent associée à une faible musculature oro-faciale et à une position basse de la langue, pouvant mener aux malocclusions et au potentiel de développer des problèmes de respiration pendant le sommeil chez les enfants. Objectifs: Évaluer l’efficacité de la thérapie oro-faciale myofonctionnelle sur le rétablissement d’une déglutition physiologique et d’une respiration nasale en développant une posture linguale et labiale normale au repos. Méthodes: Cette étude contrôlée randomisée prospective à simple aveugle a évalué 37 patients (six à quatorze ans) divisés en deux groupes où un groupe a reçu une thérapie complète (7 séances), comprenant des exercices pour la correction du patron de déglutition et de la posture linguale, et l’autre groupe a reçu une thérapie sommaire, corrigeant seulement la posture linguale (3 séances). Des suivis à trois mois et à un an post-traitement ont été effectués pour les deux groupes. Résultats: Les résultats des deux traitements, soient la thérapie complète et la thérapie sommaire, sont similaires (p = 0.59) et également efficaces pour la correction de la déglutition atypique et le rétablissement d’une respiration nasale, avec une différence significative entre les évaluations avant et après traitement (p = 0.001), qui demeure stable après un an post-traitement. Conclusion: Le traitement avec des exercices spécifiques pour une correction d’une propulsion linguale ne serait pas une composante absolue d’une thérapie oro-faciale myofonctionnelle afin de rétablir une posture linguale adéquate au repos et un patron de respiration nasale chez les enfants n’ayant pas d’autre problème fonctionnel connu. Introduction: Mouth breathing is often associated with a weak orofacial musculature and a low resting tongue position, leading to malocclusion and potentially sleep-disordered breathing in children. Objective: To evaluate the effect of orofacial myofunctional therapy on the reestablishment of a mature pattern of swallowing and nasal breathing by stabilizing a proper position of the tongue and lips at rest. Methods: This prospective randomized single-blind controlled study evaluated 37 patients (age six to fourteen years) divided into two groups who received either a complete orofacial myofunctional therapy (7 sessions) including swallowing pattern and tongue posture, or a simplified therapy modifying their tongue posture (3 sessions). Both groups were seen at three months and one year following treatment completion. Results: Results suggested that treatment outcomes were similar when treating tongue-lip posture at rest along with tongue thrust, and treating without addressing tongue thrust (p = 0.59). Both treatments were efficacious as there was a significant difference between the pre- and post- evaluations for both groups (p < 0.001), and these differences remained stable at the one year follow-up. Conclusion: Treating a tongue thrust habit with specific related exercises, may not be a necessary component of an orofacial myofunctional therapy to reestablish tongue posture at rest and nasal breathing in children with no other functional problems.

Résumé :

Severe community-acquired pneumonia (SCAP) remains the most common infectious reason for admission to the intensive care unit (ICU), reaching a mortality rate of 30–40%. The microbial pattern of the SCAP has changed with S. pneumoniae still the leading pathogen, but a decrease of atypical pathogens, especially Legionella and an increase of viral and polymicrobial pneumonias. IDSA/ATS issued guidelines on the management of CAP including specific criteria to identify patients for ICU admission with good predictive value. The first selection of antimicrobial therapy should be started early covering all likely pathogens, depending on the presence of the risk factors for Pseudomonas aeruginosa infection. Combination therapy may be useful in patients with non-refractory septic shock and severe sepsis pneumococcal bacteraemia as well. The challenges include the emergence of new pathogens as community-acquired methicillin-resistant Staphylococcus aureus, new influenza virus subtypes and the high prevalence of multidrug resistance, mainly from institutionalizing patients.

Résumé :

This chapter is an auteurist analysis that establishes the fundamental sonic patterns of Haneke’s work, especially as they create impact through concentrated moments. Like Mother Courage’s silent scream, these moments are self-consciously constructed to unsettle us, raise questions, challenge conventions of representation, and demand our emotional and intellectual reactions to them as such. This close analysis of The Seventh Continent illuminates the dominant sonic patterns of Haneke’s cinema, including: heightened sound effects of everyday objects and actions, atypical emphasis on absent sound and silences, the non-sutured use of sound, the use of music as “noise,” sound effects that are carefully “orchestrated,” pared-down dialogue, abrasively depersonalized and often acousmatized speech, and the sparing use of music that is clearly meant to be heard.

Résumé :

This first empirical chapter provides an in-depth analysis of changes to the models of industrial relations in six countries, considering general patterns of change, their sources, and their precise impact. A general trend towards liberalization plays out differently depending on power resources, institutional constellations, and historical trajectory. Societal trends, including increasing female and ethnic minority labour market participation and increases in atypical forms of employment, present challenges for trade unions. Employer associations are losing members, but can wield the powerful threat of outsourcing abroad. Finally a tour d’horizon of education and training systems establishes how they link into the structure of labour markets.

Résumé :

The main diseases caused by mycobacterial infection are tuberculosis (TB) and leprosy. Despite a fall in the prevalence of these diseases over the last decade, they are still significant causes of morbidity and mortality worldwide. Atypical mycobacterial infections are encountered less frequently. Immigration patterns, the frequency of human immunodeficiency infection, and the increased numbers of patients on immunosuppressive treatments render mycobacterial infections relevant not only to physicians in the developing world where they traditionally occurred but also in the developed world. Skeletal TB occurs in 1–3% of cases of TB infection, and is more frequently encountered in the immunocompromised. A high index of suspicion is required, diagnosis relies on a combination of clinical features and radiological, histological, and microbiological tests. Multidrug regimens are required for treatment with surgery in selected cases. Leprosy is caused by M. leprae infection. The disease is still a leading cause of disability worldwide. Diagnosis is usually clinical. The course of the disease is indolent but may be interrupted by acute inflammatory reactions, which contribute to nerve damage and disability. Treatment aims at eliminating the mycobacteria using multidrug regimens, and management of complications including leprosy reactions and long-term nerve damage. Atypical mycobacterial infections affecting bone and joints are uncommon; they usually follow direct inoculation of the pathogen. Haematogenous dissemination is encountered in immunocompromised patients. These microorganisms are not usually susceptible to the same drug regimens used in the treatment of tuberculosis.

Résumé :

Despite the predominant illness burden, evidence-based treatment, and by extension regulatory approved, for acute bipolar depression is significantly less than evidence bases in acute mania and maintenance treatment. Complicating this deficit has been persistent use of unimodal antidepressant therapy without clear and convincing benefit. Successful regulatory-approved drug development has focused on atypical antipsychotic therapy. Evidence-based treatments also include lamotrigine and divalproex by meta-analyses and a number of manual-based psychotherapies. In contrast, unimodal antidepressants as a class for bipolar depressed patients as a group appear to provide substantial benefit and may pose risk for mood destabilization. Promising novel and neuromodulatory treatments while encouraging require further systematic investigation. Understanding unimodal antidepressant response and risk patterns in bipolar disorder has immediate clinical implications. Moreover, evidence-based guidelines will need to bridge more individualized or precision-based treatment interventions.

Résumé :

Creativity, a process that generates novel and meaningful ideas, involves increased association between task-positive (control) and task-negative (default) networks in the human brain. Inspired by this seminal finding, in this study we propose a creative decoder within a deep generative framework, which involves direct modulation of the neuronal activation pattern after sampling from the learned latent space. The proposed approach is fully unsupervised and can be used off- the-shelf. Several novelty metrics and human evaluation were used to evaluate the creative capacity of the deep decoder. Our experiments on different image datasets (MNIST, FMNIST, MNIST+FMNIST, WikiArt and CelebA) reveal that atypical co-activation of highly activated and weakly activated neurons in a deep decoder promotes generation of novel and meaningful artifacts.

Résumé :

Middle aged female presented with generalised lymphadenopathy and fever for last one month. Peripheral blood findings were within normal limits. There was no extra nodal involvement. FNAC performed initially from a cervical node suggested possibility of Hodgkin’s lymphoma and a whole node biopsy was performed. Histopathogical examination revealed effaced nodal architecture and a polymorphous population of lymphocytes, plasma cells, neutrophils and scattered large mononuclear cells with prominent nucleolus. An initial panel of CD3, CD20, LCA, CD15, CD30 and PAX5 was performed. The large atypical cells were positive for LCA, CD3 and CD30 with variable positivity for CD15. CD 30 showed Golgi and membranous staining. These large atypical cells were negative for PAX5 and CD20. In view of above findings, Hodgkin’s lymphoma was ruled out and a possibility of Non- Hodgkin’s lymphoma was considered. Further IHC markers were performed which included CD2, CD5, CD7, EMA, Alk, CD10 and KI67. CD5 showed variable positivity. The cells of interest were negative for CD2, CD7, ALK and EMA. Ki 67 index was 70-80%. Overall histological and IHC findings favoured Alk negative Anaplastic large cell lymphoma. Differential diagnosis considered was peripheral T cell lymphoma (NOS). Hodgkin’s lymphoma, peripheral T cell lymphoma (NOS) and anaplastic large cell lymphoma share common histomorphological findings. With careful analysis of Immunohistochemistry, it is easier to categorise Hodgkin’s lymphoma. ALK negative anaplastic large cell lymphoma and peripheral T cell lymphoma (NOS) are difficult to categorise and show overlapping features. We in this case have discussed clinical, histomorphological and IHC pattern of Alk negative Anaplastic large cell lymphoma.

Résumé :

Objective: The aim was to evaluate an atypical case due to the rare pathologic finding of metaplastic breast carcinoma in a young woman, with an aggressive pattern. Case Report: A 45-year-old female presented with suspicious palpable right axillary lesion at level 1 topography of 2.5 cm size on the physical examination. No breast mass was palpable. Mammography was BIRADS classification 1. Breast and axillar ultrasound done 2 months before showed benign findings on the left side and axillary lymph node (LN) of 2.3 cm and breast nodule of 1.1×0.9 cm on the right side. Core-needle biopsy showed fibroadenoma in the right-sided breast nodule and metastatic carcinoma in the axillary LN. Immunohistochemistry expression of the markers was consistent with breast origin and was progesterone and estrogen receptors positive and HER-2 negative. Magnetic resonance imaging (MRI) showed this atypical LN with 1.5 cm. Clinical staging is T0N1M0. Neoadjuvant chemotherapy was performed with Adriamycin, cyclophosphamide, and paclitaxel. There was tumor remission with another MRI and ultrasonography showed the node metastasis with 1 cm. Right radical mastectomy was performed. Anatomopathology showed cytoarchitectural changes due to chemotherapy, complete pathological response in the LN, and immunohistochemistry unchanged. In addition, tumorectomy were performed in the left-sided nodule, with anatomopathology showing ductal ectasia and histiocitary abscess. Radiotherapy at the supraclavicular area and tangents was performed and tamoxifen was prescribed. The patient remained cancer free for 2 years after surgery. Conclusion: Metaplastic carcinoma represents less than 1% of breast cancers. Histologically, it is invasive and has subtypes based on the proportion of squamous, mesenchymal, and heterologous elements, such as cartilage and bone. Most common in women in the fifth decade and rare in younger than 35 years old. Usually, it is triple negative and has hematogenous dissemination, with little LN involvement and more distant metastasis. There is currently no described standard treatment. Owing to aggressiveness and poor prognosis, chemotherapy and modified radical mastectomy are performed. It is often refractory to standard regimens, so chemotherapy is indicated through the extrapolation of current data to invasive ductal carcinoma. The metastasis rate is about 35% in 5 years. The main prognostic factor is the size of the tumor at the time of diagnosis, LN metastasis, and poorly differentiated tumors.

Résumé :

Introduction : Colloid breast carcinoma is a rare variant of invasive ductal carcinoma, representing 1% to 6% of the cases. It is characterized by rich deposition of extracellular mucin upon anatomopathological analysis (AP). In general, it has positive hormone receptors, inclusion in the Luminal A molecular subtype, and an epidemiological profile of older women. Its behavior is usually indolent, associated with a low grade and favourable prognosis. It is unlikely to infiltrate axillary lymph nodes or be associated with metastatic potential. We present a case report of a patient with invasive colloid carcinoma of the breast associated with ductal carcinoma in situ (DCIS) and early axillary recurrence of a colloid pattern, contesting the mild behavior that is the gold standard in the literature. Case report: A 63-year-old patient, without relevant risk factors, was admitted due to a palpable nodule in the upper outer quadrant (UOQ) of her left breast (LB). Radiological exams showed a nodular lesion of 15x16x10 mm, heterogeneous and non-circumscribed associated with microcalcifications, with core biopsy showing colloid carcinoma. The axillae were clinically and radiologically negative. She underwent a sentinel lymph node biopsy and lumpectomy. AP results showed invasive colloid carcinoma, grade 2, measuring 1.7 cm, associated with cribiform DCIS occupying 20% of the total area of the neoplasia, free margins and three negative sentinel lymph nodes. Immunohistochemistry was compatible with Luminal A. Treatment with radiotherapy and the use of tamoxifen followed. During follow-up, in July 2020, a physical examination showed thickening in the UOQ and a hardened palpable lymph node on the left. Routine examinations showed a complex nodule compatible with clinical thickening in the UOQ and grouped and heterogeneous microcalcifications in the retroareollar region of the LB, in addition to axillary lymphadenopathy with asymmetric cortical thickening at ipsilateral level I. For better elucidation, breast magnetic resonance imaging was requested, which showed areas suggestive of fibrocicatrial changes and suspicious-looking lymph node enlargement on the left. Fine-needle aspiration biopsy (FNAB) guided by ultrasound was performed, compatible with positivity for atypical cells. Thereby, a new surgical approach was performed: mastectomy and level I axillary node dissection on the left. AP was compatible with 0.6mm DCIS associated with intraductal papilloma without atypia of LB and 1 in 6 lymph nodes, positive for diffuse infiltration by colloid pattern carcinoma. Today, the patient is being followed up, using anastrozole, without oncological changes in other follow-up exams. Cases that deviate from the standard in literature, such as the exposed surprisingly aggressive behavior of a rare variant, should be reported to encourage discussions about adequate approach and treatment.
