Microproteinuria is mainly associated with UC and its activity but not affected by 5-ASA.

From 574 referrals, the EDS correctly classified as higher risk all but one patient with cancer. Some 34·0 per cent of patients identified as lower risk could have been investigated less urgently. This simple scoring system permits sensitive prioritization of patients referred with dysphagia, and enables more efficient use of investigative resources.

This study suggests that endoscopic treatment modalities are helpful and safe methods in the treatment of biliary complications of hepatic hydatidosis before and after definitive surgical management of the hydatid cysts.

T h e p r e s e n t a t i o n o f c l i n i c a l s y m p t o m s d u e t o decompression during diving, varies significantly, as mainly minor disturbances for the gastrointestinal tract in particular have been reported. The following case debates whether diving can cause severe symptoms from the gastrointestinal system. We describe a clinical case of ischemic colitis presented in a 27-year-old male, who manifested abdominal pain while in the process of scuba diving 20 meters undersea, followed by bloody diarrhoea as soon as he ascended to sea level. Taking into account his past medical history, the thorough, impeccable clinical and laboratory examinations and presence of no other factors predisposing to ischemia of the colon, we assume that a possible relationship between diving conditions and the pathogenesis of ischemic colitis may exist. This unusual case might represent a hematologic manifestation of decompression sickness, due to increased coagulability and/or transient air emboli, occurring during a routine scuba diving ascent to sea level.
