Perturbação Factícia Bolhosa Simulando Penfigoide Bolhoso: Relato de Caso e Revisão da Literatura

Factitious disorder in dermatology is a dermatosis occuring with increasing frequency all over the world. Prevalence is reported around 2% in dermatology clinics but it is probably underdiagnosed, since the patient is not usually aware of its self-inflicted nature. When manifested by bullous lesions, it can be confused with autoimmune bullae. We report the case of a 59-year-old patient accompanied by psychiatry for severe depression with psychotic symptoms, dissociative amnesia, Munchausen syndrome and fibromyalgia who developed tense blisters on the dorsum of her left foot. The findings of the first histopathological examination suggested bullous pemphigoid and treatment with prednisone was performed. Due to the persistence and fixed location of the lesions, psychiatric history and negative direct immunofluorescence, a new histopathological examination was performed and interpreted as a case of bullous factitious disorder.A perturbação factícia na dermatologia é uma dermatose que vem ocorrendo com maior frequência na população mundial. A prevalência em torno de 2% reportada nas clínicas dermatológicas é provavelmente é subdiagnosticada, já que o paciente não costuma estar ciente da sua natureza autoinfligida. Quando se manifesta por lesões bolhosas, pode ser confundida com doenças bolhosas autoimunes. Relata-se o caso de uma paciente de 59 anos acompanhada pela psiquiatria por depressão grave com sintomas psicóticos, amnésia dissociativa, síndrome de Munchausen e fibromialgia, que desenvolveu bolhas tensas no dorso do pé esquerdo. Os achados do primeiro exame histopatológico sugeriam penfigoide bolhoso, sendo realizado tratamento com prednisona. Devido à persistência e localização fixa das lesões, aos antecedentes psiquiátricos e à imunofluorescência direta negativa, novo exame histopatológico foi realizado e interpretado como um caso de perturbação factícia bolhosa

Reação Hanseniásica Persistente 8 Anos Após Conclusão da Terapêutica: Desafio para Médicos e Pacientes

Introduction: In addition to infection with Mycobacterium leprae, type 1 and 2 reactions represent acute inflammatory events in the chronic course of multibacillary leprosy, which may persist for long periods. Case Report: A young woman presenting borderline lepromatous leprosy and persistent type 2 reaction with difficult clinical conduction. Discussion: The case illustrates the diagnostic challenge in leprosy with a systemic inflammatory response, more expressive than the dermato – neurological features. The clinical, histopathological and therapeutic implications, as well as risk factors for reaction and also polymerase chain reaction 8 years after being discharged from treatment of multidrug therapy are discussed.Introdução: Para além da infecção pelo Mycobacterium leprae, as reações tipo 1 e 2 representam eventos inflama- tórios agudos, no curso crónico da hanseníase multibacilar, mas que podem ser recorrentes e tardias. Caso Clínico: Jovem com quadro de reação tipo 2 no contexto de hanseníase borderline lepromatosa, persistente e de difícil condução clínica. Discussão: O caso ilustra o desafio diagnóstico na hanseníase com resposta inflamatória sistémica, mais expressiva que o quadro dermato – neurológico. São discutidas as implicações clínicas, histopatológicas e terapêuticas, além de fatores de risco para reação e a positividade da reação em cadeia da polimerase 8 anos após a alta da poliquimioterapi

Impact of gender in early structural changes of contrast induced nephropathy in rats

Abstract Introduction: Contrast-induced nephropathy (CIN) is a major iatrogenic cause of acute kidney injury. Experimental studies have shown that intravascular injection causes intense vacuolization of the contrast agent in the proximal renal tubules cells, preceding the increase in serum creatinine, and that the female may be at a higher risk for CIN. Objective: To study the early kidney histomorphometric changes in contrast-induced nephropathy according to the gender. Methods: Twenty previously uninephrectomized Wistar rats were divided into 4 groups (n = 5): control males; control females; contrast exposed males; and contrast exposed females. The animals were sacrificed immediately after contrast administration and kidney tissue samples were collected for histomorphometric analysis. The research project was approved by the Research Ethics Committee of the School of Medicine of Universidade Federal Fluminense. Results: There was a more intense presence of microvacuoles in proximal tubules in the rats exposed to contrast than in the control groups. Such proximal tubular vacuolation was more intensive in the female rats (p = 0.001). Conclusion: Proximal tubular vacuolation is a very early change in CIN and is more intensive in female than in male rats

Evaluation of a quality improvement intervention to reduce anastomotic leak following right colectomy (EAGLE): pragmatic, batched stepped-wedge, cluster-randomized trial in 64 countries

Background Anastomotic leak affects 8 per cent of patients after right colectomy with a 10-fold increased risk of postoperative death. The EAGLE study aimed to develop and test whether an international, standardized quality improvement intervention could reduce anastomotic leaks. Methods The internationally intended protocol, iteratively co-developed by a multistage Delphi process, comprised an online educational module introducing risk stratification, an intraoperative checklist, and harmonized surgical techniques. Clusters (hospital teams) were randomized to one of three arms with varied sequences of intervention/data collection by a derived stepped-wedge batch design (at least 18 hospital teams per batch). Patients were blinded to the study allocation. Low- and middle-income country enrolment was encouraged. The primary outcome (assessed by intention to treat) was anastomotic leak rate, and subgroup analyses by module completion (at least 80 per cent of surgeons, high engagement; less than 50 per cent, low engagement) were preplanned. Results A total 355 hospital teams registered, with 332 from 64 countries (39.2 per cent low and middle income) included in the final analysis. The online modules were completed by half of the surgeons (2143 of 4411). The primary analysis included 3039 of the 3268 patients recruited (206 patients had no anastomosis and 23 were lost to follow-up), with anastomotic leaks arising before and after the intervention in 10.1 and 9.6 per cent respectively (adjusted OR 0.87, 95 per cent c.i. 0.59 to 1.30; P = 0.498). The proportion of surgeons completing the educational modules was an influence: the leak rate decreased from 12.2 per cent (61 of 500) before intervention to 5.1 per cent (24 of 473) after intervention in high-engagement centres (adjusted OR 0.36, 0.20 to 0.64; P < 0.001), but this was not observed in low-engagement hospitals (8.3 per cent (59 of 714) and 13.8 per cent (61 of 443) respectively; adjusted OR 2.09, 1.31 to 3.31). Conclusion Completion of globally available digital training by engaged teams can alter anastomotic leak rates. Registration number: NCT04270721 (http://www.clinicaltrials.gov)
