Colon agenesis with ileovesical fistula and anorectal malformation.

Colonic agenesis is a rare cause of congenital bowel obstruction and is usually associated with other malformations such as abdominal wall defects or gastrointestinal, cardiac, urogenital, and musculoskeletal lesions. Although many uncommon types have been reported, ileovesical fistula (IVF) associated with total colonic agenesis (TCA) has not been reported in a newborn with anorectal malformation (ARM). This is the first report of a 1-day-old newborn with ARM, IVF, and TCA.

An oblique anastomosis has more linear length than a transverse anastomosis of a tubular structure in oesophageal anastomosis.

Introduction: Oesophageal stricture continues to be a challenging paediatric surgical problem. This study aimed to compare the results of oblique and transverse anastomosis to prevent anastomotic stricture that occurred following oesophageal repairs.

The effect of nondipping blood pressure patterns on cardiac structural changes and left ventricular diastolic functions in normotensives.

Background: Cardiac structural changes have been reported to be more prominent in nondipper normotensives than the dipper ones. But the influence of nondipping status on cardiac diastolic functions of normotensives has not been studied yet. In this study, we investigated the effect of nondipping status on both cardiac structural changes and left ventricular (LV) diastolic functions in normotensives.

Pleomorphic adenoma of the trachea mimicking bronchial asthma: report of a case.

Benign tracheal tumors are rare and difficult to diagnose. A delay in diagnosis is common because the symptoms mimic those of bronchial asthma. We report the case of a 42-year-old woman who was treated for asthma for 2 years before a diagnosis of pleomorphic adenoma of the trachea was made.
