A further series of 41 adult patients with late-onset hepatic failure was investigates with respect to aetiological factors, particularly hepatitis C and E, which have been identified since our earlier report of this condition. The increased use of transplantation and its impact on survival overall is assessed. Comparison is made with 64 patients admitted over the same period with fulminant hepatic failure of non-A, non-B aetiology. Screening for the hepatitis viruses revealed three cases of hepatitis A and one case of Epstein Barr virus hepatitis. There were no cases of hepatitis C or hepatitis E virus detected by enzyme immunoassay and reverse transcriptase/polymerase chain reaction techniques, although three patients had positivity for IgG anti-hepatitis E virus, demonstrating previous exposure. Serum autoantibodies in a titre greater than or equal to 1:40 were present in 29% of samples tested and in three cases, titres of SMA or ANF were greater than 1:320. In a further five cases, a potentially hepatotoxic agent had been given within 3 months of the onset of symptoms, leaving the majority of patients (29) with no identifiable cause for their disease. The frequency of symptoms, however, including nausea, abdominal discomfort with the subsequent development of ascites, encephalopathy and renal impairment suggest a similar disease process in these patients. Analysis of liver biopsy material showed similar patterns on all cases of map-like necrosis with nodular regeneration and without other additional features of aetiological significance. Differences in clinical and histological changes for the non-A, non-B fulminant hepatic failure comparison group reflect the tempo of disease process rather than the nature and cause of the liver damage. The introduction of transplantation has led to a marked improvement in survival (39% overall in the earlier series). In the 21 patients in whom transplantation was carried out, the 1-year actuarial survival is currently 55%. Treatment of late-onset hepatic failure with corticosteroids and the use of Prostaglandin E1 and interferon in individual cases has been disappointing, and the emphasis in management should be placed on teh early referral of such patients to a centre offering transplantation.

Malignant rhabdoid tumor (MRT), described for the first time in 1978 in the kidney, has rarely been reported in other organs including the brain and has involved adults in only 3 cases. We described a case of MRT in a 32-year-old woman who presented with severe headache, nausea and sudden onset of visual disturbance. MRI showed a well-enhanced mass at the suprasellar region. Subtotal removal of the tumor was performed. However, tumor regrowth occurred after the operation (doubling time, 8.36 days) and spinal dissemination was detected. Therefore, chemotherapy and radiotherapy were administered focusing on the suprasellar lesion and the spinal cord. Pathologically, light micrographs showed rhabdoid cells with large, round, single or double nuclei with one prominent nucleolus and eosinophilic cytoplasmic inclusions. Electron micrographs were made of typical rhabdoid cells displaying bundles of intermediate filaments within the perikaryon. In immunohistochemical studies, EMA, vimentin, cytokeratin and SMA were positive. Pathological findings were consistent with those of MRT. Optimal treatment for this tumor has not been established. Our case may be useful in defining treatment for MRT.

Neurofibromas of the stomach can occur in the course of Recklinghausen's disease. Sporadic gastric neurofibroma appears rarely. This tumour may look like an ulcer and can be a cause of abdominal pain, nausea, and bleeding from the gastrointestinal tract. We reported a 61-year-old women complaining of stomachache for several months. Gastroscopy revealed a tumour with ulceration in the prepyloric part of the stomach. Helicobacter pylori infection was also present. Helicobacter pylori eradication and prolonged treatment of proton pump inhibitors did not decrease the ailments or the size of the tumour. It was not possible to determine the nature and origin of the tumour by carrying out examinations such as endoscopic ultrasound and computed tomography of the abdomen. Only after surgery and histopathological examination with immunohistochemistry was this tumour identified as a neurofibroma. In order to differentiate the tumour the following immunohistochemical examinations were carried out: CD34 (slightly +), CD117 (-), S-100 (+), desmin (-), NSE (+), GFAP (-), SMA (-), bc12 (-), CD99 (-), ALK1 (-), and MiB (1-1.5%). In such cases excision of the tumour is the preferred treatment.

A case of a 39-year-old woman diagnosed with superior mesenteric artery syndrome after a 25-year history of nausea, vomiting, and abdominal pain that began as a teenager and the absence of any significant weight loss illustrates the diagnostic complexity of this entity, particularly among teenagers and young adults who present with these symptoms. The patient underwent multiple upper endoscopies and serologic evaluations before a contrasted CT demonstrated an acutely angled SMA and duodenal compression, prompting the diagnosis of SMA syndrome. This case underscores the importance of including congenital SMA syndrome on the differential in young people without an obvious cause of persistent nausea, vomiting, and abdominal pain.

Chronic Mesenteric ischemia is an episodic hypoperfusion of small intestine due to atherosclerotic narrowing of mesenteric vessels. Typically, patients report postprandial epigastric pain. The association of abdominal pain with eating results in fear of eating and weight loss. Some patients present atypically with nausea, vomiting and/or GI bleeding likely from gut ischemia. We present here a case of 67-yearold male with history of COPD, Coronary artery disease and atrial fibrillation presented with hematemesis and black stools for one day. Patient reports no abdominal pain or weight loss. He was dizzy and nauseous. He was vitally stable and physical exam including abdominal exam was unremarkable except for the rectal exam which revealed black stools. Investigations revealed Haemoglobin of 16.1 and hematocrit of 45, WBCs of 34000 with 83% neutrophils and bicarbonate of 20. Patient underwent EGD for localizing the site of bleeding and showed stomach lumen completely filled with thrombus which prevented the accurate assessment if gastric mucosa. Repeat EGD was recommended and it revealed gangrenous appearing gastritis throughout with multiple clean ulcers which raised the suspicion of vascular compromise. CT angiography abdomen revealed complete proximal occlusion of Superior Mesenteric artery and near complete occlusion of celiac artery. He underwent successful SMA bypass from left iliac to mid SMA with PTFE graft. Symptoms of mesenteric ischemia can be non-specific and can mimic other aetiologies. Clinicians should consider this diagnosis in elderly patient with risk factors of atherosclerosis as early diagnosis reduces complication associated with serious life-threatening disease.

Superior mesenteric artery syndrome (SMA syndrome) or Wilkie's syndrome is a rare etiology of duodenal obstruction due to compression of the third portion of the duodenum between the superior mesenteric artery and the aorta. Physical and laboratory findings are often non-specific but imaging methods are useful for diagnosing the condition. A 46-year-old female patient presented to the outpatient clinic of our internal medicine department with a 2-year history of epigastric pain, nausea, early satiety and weight loss of 15 kg. Previous studies were inconclusive. The patient underwent computed tomography enterography and its findings were consistent with SMA syndrome. Currently the patient is being followed by General Surgery and Nutrition and is under nutritional measures in order to optimize her body mass index to decrease possible surgical complications. This case report emphasizes the importance of clinical suspicion and careful investigation when considering less common etiologies for frequent gastrointestinal symptoms.
