A rare case of cystic hygroma in neck and extending into thoracic cavity.

Introduction: Cystic hygroma is a benign swelling of the neck among the pediatric population. It is a fluid-filled sac resulting from blockage in the lymphatic system and is commonly located in the cervical region and axilla.

Case Presentation: We present a rare case of a large cystic hygroma in the neck and the thorax in a 12 year's old male.

A rare case of huge maxillary ameloblastoma in a 3.5 years old girl.

Ameloblastoma is a benign locally invasive odontogenic tumor. It is the most common odontogenic tumor [1]. Usually, in the middle-aged population, it is more common in the mandible with about 5-20% occurring in the maxilla.

Serum nitrates and vasoactive intestinal peptide in patients with gastroesophageal reflux disease.

Background: The normal esophageal motility is a balance between excitatory cholinergic "muscarinic" innervations and noncholinergic nonadrenergic inhibitory innervations. The latter is mediated by nitric oxide (NO) and/or vasoactive intestinal polypeptide (VIP).

Methods: The study included 50 patients with gastro-esophageal reflux disease (GERD), and 10 healthy controls of matched age and sex.

Clinical and pharmacokinetic study of praziquantel in Egyptian schistosomiasis patients with and without liver cell failure.

The pharmacokinetics and therapeutic efficacy of praziquantel (Distocide; Epico, El-Asher-Men-Ramadan City, Egypt) were studied in 40 patients with schistosomiasis mansoni and various degrees of hepatic dysfunction. The patients were allocated into four groups: the first included 10 patients with simple active schistosomiasis while the other three were made up of patients with schistosomiasis associated with liver cirrhosis and splenomegaly according to Child's classification of hepatocellular function. Every patient was treated with 40 mg/kg of praziquantel as a single oral dose.

Pharmacokinetics of aztreonam in patients with liver cirrhosis and ascites.

The pharmacokinetics of aztreonam were studied in six healthy male subjects (group I) and 12 male patients with post-hepatitis liver cirrhosis and ascites. Patients were allocated into two groups according to serum creatinine; group II included nine patients with serum creatinine. < or = 15 mg/L while group III included three patients with serum creatinine > 15 mg/L.
