Females with XY karyotype and streak gonads are classified as presenting XY gonadal dysgenesis. These patients are at higher risk of developing malignancy in their gonads; in such cases prophylactic surgical removal is indicated. This article reports a case in which a patient with dysgenesis presented 45,X/46,XY karyotype. Laparoscopic prophylactic gonadal resection was performed. Laparoscopy plays an important role in exploring pelvic structures and allows the diagnosis, prognosis and treatment of lesions. In addition, it provides an effective method for gonadectomy. The prophylactic removal of dysgenetic gonads using this surgical technique has been preferred in selected patients lately., Mulheres com cariótipo XY e gônadas em fita são consideradas portadoras de disgenesia gonadal. Essas pacientes apresentam um risco mais alto de desenvolver doenças nas gônadas. Em tais casos, a remoção cirúrgica profilática é indicada. Este artigo relata o caso de uma paciente com disgenesia, apresentando cariótipo 45,X/46,XY. Foi realizada ressecção profilática das gônadas através de laparoscopia. A laparoscopia tem um papel importante na exploração de estruturas pélvicas e permite o diagnóstico, o prognóstico e o tratamento de lesões. Além disso, oferece um método efetivo para a gonadectomia. A remoção profilática das gônadas disgenéticas utilizando essa técnica cirúrgica tem sido preferida em pacientes selecionados.

Objective: Hepatitis C virus transmission in assisted reproduction may pose a risk for the baby, technicians, and gametes or embryos from non-contaminated parents. This study aimed at determining the prevalence and risk factors for hepatitis C virus infection in a group of infertile couples.Methods: Four hundred and nine patients attending the infertility clinic at Hospital de Clínicas de Porto Alegre, Brazil, between 1997 and 1998, were screened for anti-HCV (ELISA) and HBsAg (ELFA). Hepatitis C virus (HCV) infection and semen viremia was also investigated using HCV RNA detection Results: All subjects were negative for HBV and HIV. The overall prevalence of anti-HCV was 3.2% (8/ 248) among women and 3.7% (6/161) among men. From the 14 HCV-positive patients, two were lost, and serum was collected from the remaining 12 patients for assessment of HCV RNA, resulting in five HCVpositive cases (one woman and four men). Only one of these positive cases had viremia levels > 500,000 RNA copies/ml. There was a significant risk association for being HCV-positive in women with HCV-positive male partners (P < 0.001). In male patients, the correlation between use of intravenous drugs and HCVpositivity was also significant (P < 0.001).Conclusions: Infertile patients should be screened before assisted reproductive technology (ART) procedures, since the risk for vertical and laboratory HCV infection is not well determined, and HCV prevalence is not negligible in this group., Objetivo: A possibilidade transmissão do vírus da hepatite C através dos gametas pode acarretar riscos para o pessoal técnico, bem como para os envolvidos no processo e para o próprio feto. Este estudo teve como objetivo determinar a prevalência e os fatores de risco da infecção pelo vírus da hepatite C em um grupo de casais inférteis.Métodos: Em 409 pacientes atendidas no ambulatório de infertilidade do Hospital de Clínicas de Porto Alegre (HCPA), entre 1997 e 1998, realizou-se triagem sorológica para antiHCV (ELISA) e HBsAg (ELFA). A infecção pelo vírus da hepatite C (HCV) e a viremia seminal também foram investigadas com detecção de HCV-RNA.Resultados: A prevalência geral de anti-HCV foi de 3,2% (8/248) entre as mulheres e 3,7% (6/161) entre os homens. Todos os indivíduos eram negativos para o vírus da hepatite B (HBV) e HIV. Das 14 pacientes HCV-positivas, duas foram perdidas, e foi coletado soro das 12 pacientes remanescentes para detecção de HCV-RNA, resultando em cinco casos HCVpositivos (uma mulher e quatro homens). Apenas um dos casos positivos tinha nível de viremia > 500.000 cópias de RNA/ml. Houve uma associação de risco significativa da positividade para HCV nas mulheres com parceiros HCV-positivos (P < 0,001). Em pacientes masculinos, a correlação entre uso de drogas endovenosas e positividade para HCV também foi significativa (P < 0,001).Conclusões: Pacientes inférteis deveriam ser triados para HCV antes dos procedimentos de tecnologia de reprodução assistida (TRA), uma vez que o risco de infecção vertical e laboratorial pelo HCV não está bem determinado e a prevalência do HCV não é desprezível neste grupo.

PANDAS are known as the spectrum of autoimmune pathologies related to a previous or current infection by group A beta-hemolytic streptococcus (SBEGA), dealing with several neuropsychiatric manifestations that mainly affect pediatric age. The main features consist of behavioral disease or movement disease characterized by acute-onset, presenting especially through infant period or adolescence. Specific manifestations, occurring during the progression of the disease, are the presence of otorhinolaryngologic symptoms (ENT) and orofacial movement disorders associated with temporomandibular joint pain.We enrolled 130 children (5-15 years) with a clinical diagnosis of PANDAS between 2012 and 2018. Participants were assessed using ENT specific parameters, PSG to examine respiratory disorders and conventional audiological evaluation. Descriptive and comparative statistical analyses were performed with a control group of 51 healthy patients.The prevalence of ENT symptoms associated was significantly detected in 88 patients of 130 in Group A (relative frequency (%) 67.6; p=0.041) and in 51 patients of 130 in the control Group B (relative frequency (%) 39.2; p=0.063). In relation to prevalence of SDB, 54 subjects have presented nocturnal respiratory obstructive symptoms from mild to severe (relative frequency (%) 61.3; p=0.033) vs. 20 patients of Group B (relative frequency (%) 39.2; p=0.055). The obstructive severity average type was correlated to the consensual adenotonsillar development (size 3-4), (relative frequency (%) 45.4; p=0.047). The audiological deficits found were mostly of transmissive type with OME correlated and linked to the presence of occasional episodes of AOM. The four PANDAS patients who presented orobuccal dystonia (relative frequency (%) 4.54; p=0.091) achieved an improvement of the algic symptoms through the exercises of self-rehabilitation.Findings from our study show that respiratory diseases, characterizing a group of patients with pandas, are the direct consequences of the malformed or hypertrophic condition and suggesting in these conditions surgical therapy as an approaching tool.
