1/5. Gastric sarcoidosis presenting with haematemesis.

    sarcoidosis is a very rare disease in singapore. Sarcoid granuloma involving the stomach alone is even more rare, and only about 21 cases have been reported in the literature up to 1953 (Scott et alii, 1953). In a review of the literature, Wadina and Melamed (1966) found 34 cases of granulomatous involvement of the stomach, all purporting to be sarcoidosis. However, on closer examination of the evidence, many of these 34 cases of so-called sarcoidosis of the stomach were subject to doubt. Bleeding from gastric sarcoidosis is also rare, and only about eight cases have been reported in the literature up to 1970. The present report presents a further example of this rare cause of upper gastrointestinal bleeding and attempts to review the significance of sarcoid granulomas in the stomach.

2/5. Case report: severe mercuric sulphate poisoning treated with 2,3-dimercaptopropane-1-sulphonate and haemodiafiltration.

    INTRODUCTION: Inorganic mercury poisoning is uncommon, but when it occurs it can result in severe, life-threatening features and acute renal failure. Previous reports on the use of extracorporeal procedures such as haemodialysis and haemoperfusion have shown no significant removal of mercury. We report here the successful use of the chelating agent 2,3-dimercaptopropane-1-sulphonate (DMPS), together with continuous veno-venous haemodiafiltration (CVVHDF), in a patient with severe inorganic mercury poisoning. CASE REPORT: A 40-year-old man presented with haematemesis after ingestion of 1 g mercuric sulphate and rapidly deteriorated in the emergency department, requiring intubation and ventilation. His initial blood mercury was 15 580 microg/l. At 4.5 hours after ingestion he was started on DMPS. He rapidly developed acute renal failure and so he was started on CVVHDF for renal support and in an attempt to improve mercury clearance; CVVHDF was continued for 14 days. methods: Regular ultradialysate and pre- and post-filtrate blood samples were taken and in addition all ultradialysate generated was collected to determine its mercury content. RESULTS: The total amount of mercury in the ultrafiltrate was 127 mg (12.7% of the ingested dose). The sieving coefficient ranged from 0.13 at 30-hours to 0.02 at 210-hours after ingestion. He developed no neurological features and was discharged from hospital on day 50. Five months after discharge from hospital he remained asymptomatic, with normal creatinine clearance. DISCUSSION: We describe a patient with severe inorganic mercury poisoning in whom full recovery occurred with the early use of the chelating agent DMPS and CVVHDF. There was removal of a significant amount of mercury by CVVHDF. CONCLUSION: We feel that CVVHDF should be considered in patients with inorganic mercury poisoning, particularly those who develop acute renal failure, together with meticulous supportive care and adequate doses of chelation therapy with DMPS.

3/5. Malignant melanoma of the gastrointestinal tract presenting as a bleeding gastric ulcer.

    Malignant melanoma involving the gastrointestinal tract is diagnosed antemortem in only a small percentage of patients with the disease. Presenting symptoms are often non-specific, causing a diagnostic problem. The vast majority of such melanomas are metastatic from a cutaneous primary, however there is evidence that the tumour can arise de novo in the gastrointestinal system. We report a 74-year-old man with malignant melanoma with an unusual presentation simulating a symptomatic gastric ulcer. He presented with epigastric pain, haematemesis and melaena. Explorative laparotomy revealed a large ulcerated tumour with several pigmented satellite nodules in the proximal stomach, multiple ileal nodules and widespread nodal and liver metastases. Proximal gastrectomy and limited small bowel resection was performed. histology revealed the tumour to be composed of nests of epithelioid cells with melanin pigment. The tumour cells showed immunohistochemical positivity for S100 protein and HMB45 antibodies. This report emphasizes that melanoma should be a diagnostic consideration in patients with gastric ulcer.

4/5. A caliber-persistent artery of the gastric wall resulting in fatal haemorrhage.

    A 12-year-old girl was admitted to hospital with haematemesis. Her family suffered from histidinaemia. Due to her numerous injuries the police suspected a crime. After a short period of clinical treatment she died. autopsy showed the left ureter to be narrowed and a consecutive abscedens pyelonephritis. Pyloric ulcer caused erosion of a caliber-persistent artery which led to death with haemorrhage. The death had nothing to do with violence. Adequate surgical treatment could have saved the patient's life.

5/5. Fatal non-malignant ulceration in the gastric tube after oesophagectomy.

    The clinical, histological, and necropsy findings of three cases of fatal, nonmalignant ulceration in the gastric tube after oesophageal resection for oesophageal malignancy are presented. The deaths occurred three, 30, and 42 months, respectively, after initial surgery. Two of the patients had received chemoradiotherapy, one at initial presentation, and one for a recurrence 18 months after surgery. In two patients death was due to an aspiration pneumonia, consequent on the development of a gastrobronchial fistula. The third patient died after a massive haematemesis. In none of the cases was there any evidence of residual or recurrent malignancy at necropsy, although in the two cases where radiological and endoscopic assessment was performed before death, recurrent tumour had been clinically diagnosed. As improved surgical techniques reduce the incidence of death due to anastomotic leakage and combined modality treatment regimens offer improved prospects of tumour remission, deaths from other causes will assume a greater importance. As such, the possibility that ulceration in the gastric tube may be due to causes other than tumour recurrence deserves greater recognition.
