Mutilação Genital Feminina - a Importância de Reconhecer e de Saber como Agir

Female genital mutilation, also named female genital cutting or female circumcision, refers to all practices involving total or partial removal of female external genitalia, or causing other lesions without an established health benefit. The World Health Organization estimates that 130 million women have been submitted to genital mutilation and 3 million are annually exposed to such risk in Africa. It has classified the practice of female genital mutation in four types. Portugal is considered a risk country for the practice of genital mutilation because of the high migration rates from the African continent, and women from Guinea-Bissau are at particular risk. A multidisciplinary commission published an Action Program in 2009, with measures directed at providing healthcare professionals with information on how to deal with this problem.

Different in Vivo Reactivity Profile in Health Care Workers and Patients with Spina Bifida to Internal and External Latex Glove Surface-Derived Allergen Extracts

BACKGROUND: Allergy to natural rubber latex is a well-recognized health problem, especially among health care workers and patients with spina bifida. Despite latex sensitization being acquired in health institutions in both health care workers and patients with spina bifida, differences in allergen sensitization profiles have been described between these two risk groups. OBJECTIVE: To investigate the in vivo reactivity of health care workers and patients with spina bifida to extracts of internal and external surfaces of latex gloves and also to specific extracts enriched in major allergens for these risk groups. METHODS: Gloves from different manufacturers were used for protein extraction, and salt precipitation and hydrophobic interaction chromatography (HIC) were applied to obtain the enriched latex extracts. The major latex allergens were quantified by an enzyme immunoassay. The extracts obtained were tested in 14 volunteers using skin prick tests (SPT). RESULTS: Latex glove extracts enriched in the hydrophobic allergens that are most often seen in patients with spina bifida were obtained by selective precipitation, whereas HIC produced extracts enriched in the hydrophilic allergens commonly found in health care workers. The health care workers had positive SPTs to glove extracts from internal surfaces and to the hydrophilic allergen-enriched extracts. By contrast, patients with spina bifida had larger skin reactions both to external glove extracts and to the extracts enriched with the hydrophobic major allergens for this risk group. Despite the protein concentration of these extracts being less than half the concentration of the commercial extract, the weal-and-flare reactions were of similar magnitude. CONCLUSION: Using novel latex extracts, our study showed a different in vivo reactivity pattern in health care workers and in patients with spina bifida to extracts of the internal and external surfaces of gloves, which suggests that sensitization may occur by different routes of exposure, and that this influences the allergen reactivity profiles of these risk groups

Terapêutica Endovascular de Pseudoaneurisma e Fístula Arteriovenosa em Enxerto Renal

A 31 year old male Caucasian received a renal cadaveric allograft. Reconstruction of an inferior polar artery was corrected pre-implantation. Delayed graft function occurred leading to dialysis support for one month. Graft biopsies(days 7, 15) showed acute tubular necrosis(ATN) and no rejection. Serial ultrasound (US), performed on average weekly, were compatible with ATN. On day 31, Doppler US and a CAT scan suggested for the first time a pseudoaneurysm adjacent to the implantation of the graft artery on the external iliac artery. For clinical and technical reasons, arteriography was only performed on day 67, when serum creatinine was 3.3 mg/dl. It showed a large pseudoaneurysm with an arteriovenous fistula to the right common iliac vein. Compression of the right external iliac artery was clear. In an attempt to close the arteriovenous fistula, the communication with the pseudoaneurysm was embolised with gelfoam and metallic coils with partial success. One week later, by right femoral approach a covered wallstent was placed immediately below the origin of the graft artery.Subsequent Doppler US and arteriography con-firmed closure of the communication with thepseudoaneurysm and of the arteriovenous fistula. The calibre of the right external iliac artery was then normal. By month 18, serum creatinine is stable at 2.1 mg/dl. We can only speculate on the origin of thepseudoaneurysm and of the AV fistula, whichwere not evident until one month post-transplantation. Backtable surgery was performed on thepolar not the main graft artery. Invasive angiography was irreplaceable in this unusual clinical situation.

Porokeratosis Ptychotropica of the Scrotum: Dermoscopic Evaluation of an Atypical Presentation

Porokeratosis ptychotropica is a rare variant of porokeratosis that is classically located on the gluteal and perianal regions, seldom extending to the genitalia. The authors report an atypical presentation of porokeratosis ptychotropica and discuss the use of dermoscopy in evaluating this dermatosis. Dermoscopic findings, although not specific to this variant of porokeratosis, are helpful in the differential diagnosis of other genital disorders. Histopathology, through the visualization of multiple cornoid lamellae, prevails as the gold standard for the definite diagnosis of porokeratosis ptychotropica.

Mutations in the MECP2 Gene Are Not a Major Cause of Rett Syndrome-Like or Related Neurodevelopmental Phenotype in Male Patients

Rett syndrome is a genetic neurodevelopmental disorder that affects mainly girls, but mutations in the causative MECP2 gene have also been identified in boys with classic Rett syndrome and Rett syndrome-like phenotypes. We have studied a group of 28 boys with a neurodevelopmental disorder, 13 of which with a Rett syndrome-like phenotype; the patients had diverse clinical presentations that included perturbations of the autistic spectrum, microcephaly, mental retardation, manual stereotypies, and epilepsy. We analyzed the complete coding region of the MECP2 gene, including the detection of large rearrangements, and we did not detect any pathogenic mutations in the MECP2 gene in these patients, in whom the genetic basis of disease remained unidentified. Thus, additional genes should be screened in this group of patients.
