Ureterovesical junction obstruction causes increment in smooth muscle contractility, and cholinergic and adrenergic activity in distal ureter of rabbits.

Background/purpose: The controversy in management of primary obstructed megaureter necessitates further elucidation of the underlying pathophysiology. We evaluated smooth muscle contractility, and cholinergic, adrenergic and serotonergic activity of rabbit distal ureters after ureterovesical junction (UVJ) obstruction.

Methods: Sham (SH) operation, partial obstruction (PO) and complete obstruction (CO) of the right UVJ were performed in rabbits.

A rare cause of severe periorbital edema and dermonecrotic ulcer of the eyelid in a child: brown recluse spider bite.

Spider bites are a worldwide problem. Brown recluse spider bites can lead to severe local or systemic clinical effects, such as edema, necrotic ulcer, rashes, fever, chills, nausea, vomiting, malaise, arthralgia, myalgia, hemolysis, leukocytosis, disseminated intravascular coagulation, renal failure, and death. Eyelid bites from brown recluse spiders are rare.

Neonatal tetanus in Turkey; what has changed in the last decade?

Background: Neonatal tetanus (NT) is still considered as one of the major causes of neonatal death in many developing countries. The aim of the present study was to assess the characteristics of sixty-seven infants with the diagnosis of neonatal tetanus followed-up in the Pediatric Infectious Diseases Ward of Dicle University Hospital, Diyarbakir, between 1991 and 2006, and to draw attention to factors that may contribute (or may have contributed) to the elimination of the disease in Diyarbakir.

Methods: The data of sixty-seven infants whose epidemiological and clinical findings were compatible with neonatal tetanus were reviewed.

The contribution of nitric oxide on the relaxation effects of diethylstilbestrol.

Objective: To evaluate the contribution of nitric oxide NO on the relaxation effects of diethylstilbestrol on rat uterus.

Methods: Uterine rings from 8 nonpregnant Wistar Albino rats 300-350 g in the pro-estrous phase were suspended in an organ bath and electrical field stimulation applied for recording isometric tension. The influence of NO on contractile responses of rat uterine rings was investigated.
