Variant etiologies of neonatal cholestasis and their outcome: a Middle East single-center experience.

AIM OF THE STUDY: Neonatal cholestasis (NC) constitutes a large proportion of pediatric liver disorders. Nevertheless, awareness of the variant etiologies and how to manage them appropriately are lacking. So, out of a few specialized centers, many cases pass without appropriate management. This study aimed to present our tertiary level center's experience in NC that could increase the pediatrician's awareness of handling this problematic and common medical morbidity efficiently. MATERIAL AND METHODS: It is a retrospective study in which we analyzed the NC cases admitted to the inpatient department within three years. For all recruited patients, the available data were retrieved and recorded. RESULTS: A total of 412 patients were reviewed with 20 different etiologies diagnosed. The most common cause was biliary atresia (n = 151, 37%), followed by progressive familial intrahepatic cholestasis (n = 51, 12%), neonatal sepsis (n = 39, 9%), and cytomegalovirus (n = 33, 8%). Of the 412 patients, 394 (81%) had follow-up ranging from 1 to 36 months. A total of 173 patients improved with supportive and/or specific therapy, while 108 patients died at a median age of 6 months. The commonest cause of death was liver failure (40.7%), followed by pneumonia (28.7%), sudden death (13%), septicemia (6.5%), and hepatorenal syndrome (5.5%). CONCLUSIONS: NC constitutes more than one-third of the inpatient admissions of all pediatric liver disorders and has a high rate of mortality. Awareness of the variety of etiologies and a rapid stepwise approach to diagnosis could have an impact on the outcome of this devastating disease.

Mesonephric adenocarcinoma of the vagina masquerading as a suburethral cyst.

Mesonephric adenocarcinoma (MA) of the vagina is an extremely rare tumour of the female genital tract. There are currently 22 reported cases in the published literature. Consequently, its pathophysiology and disease progression remain poorly understood.A 63-year-old woman presented with a history of a swelling in her vagina. Two-dimensional pelvic floor ultrasound and MRI demonstrated a multiloculated cyst with no malignant features. Initial workup provided a working diagnosis of a suburethral cyst. The diagnosis of MA was made on histology after excision of the cyst. Subsequent postoperative investigation showed no spread of the disease. The patient completed a course of prophylactic brachytherapy to prevent the possibility of any recurrence of disease. Due to its rarity, it remains difficult to diagnose MA of the vagina even on histological analysis. We would therefore recommend a low threshold to excise or perform tissue biopsy of unspecified vaginal masses.
