Porphyrias are inherited defects of heme synthesis with manifestations that can mimic surgical diseases; they can be provoked by administration of certain drugs. Manifestations such as abdominal pain, vomiting, tachycardia, hypertension, neuropathy, fever, confusion, and seizures have been described. Management of patients with porphyria is designed to avoid triggering drugs, such as barbiturates, and perhaps, benzodiazepines and ketamines. Nontriggering drugs should be used in the management of patients with porphyria. Because starvation can induce an attack, glucose infusions are important in the prevention and treatment of porphyria.

Rupture of an abdominal aortic aneurysm often presents with an abdominal pain, hypotension and a pulsatile abdominal mass. In the last years same clinical reports describe patients with less apparent clinical signs who were found later in their evaluation to have a contained rupture of an abdominal aortic aneurysm. The diagnosis may be delayed by consideration of other disease causing similar symptoms (herniated disc, renal colic). In these patients with confusing abdominal symptoms CT scan provides a rapid and noninvasive diagnosis. We report three cases of contained rupture of an abdominal aortic aneurysm evaluated by computed tomography with different clinical presentation: back pain for erosion into the lumbar vertebral bodies, lower extremity neuropathy and obstructive jaundice. All patients were operated on within 24 hours on admission; there was no operative mortality and survival was 100% at one year.

Transient esophageal motor dysfunction with dysphagia was observed in a 62-year-old man receiving vincristine-containing chemotherapy for non-Hodgkin's lymphoma. Neurological examinations, including muscle strength of extremities, deep tendon reflexes and cranial nerves, were normal. However, the patient complained of severe numbness in the fingertips and toes. The results of esophagogram and esophagoscopy were unremarkable. However, a significantly prolonged esophageal transit time was observed. Vincristine was considered as the causative agent. Empirical vitamin and metoclopramide were prescribed for his neurological symptoms but there was no improvement. The symptoms of dysphagia subsided spontaneously 2 weeks later. However, prompt recurrence of severe dysphagia was observed again after administration of the second and third courses of treatment, which again disappeared upon discontinuation of the drug. Peripheral nerves and the gastrointestinal tract are often affected by vincristine. Common gastrointestinal tract symptoms of vincristine neuropathy may be colicky abdominal pain and constipation. However, vincristine-induced esophageal motor dysfunction with dysphagia is uncommon but generally reversible. The oncologist and chemotherapist should be aware of this complication.

The American College of Traditional Chinese Medicine has been funded for three years to provide Chinese medical treatment to over 300 symptomatic HIV-positive patients. A recent study of the medical records of these patients, and of quarterly health surveys, has identified seven HIV-related conditions which appear to be most responsive to Chinese medicine: weight loss, diarrhea/loose stools, abdominal pain, nausea, headaches, enlarged lymph nodes, and neuropathy. For more information about the American College of Traditional and Chinese Medicine, individuals can call 415-282-9603. There is a trend toward coverage by insurers and third party payers to pay for alternative care such as traditional Chinese medicine. Companies are finding that they can save money by paying for alternative care which usually costs much less than Western medicine. Acupuncture is now covered by health insurance companies with home offices in California. For information on how to help expand health-care coverage for traditional Chinese medicine in San Francisco and California, call George Wedemeyer at 415-661-2080.

Symptoms from the gastro-intestinal tract are common and often difficult to evaluate. Specialised examination techniques are available only at a limited number of clinics. A technique based on biliary scintigraphy when measuring the transit of contents through the small intestine has been developed. The investigation is simple to perform and convenient for the patient. It can be carried out at any clinic equipped with a gamma camera. 30 healthy individuals were examined in order to obtain reference values. 23 patients were examined with scintigraphy in combination with upper gastrointestinal manometry, 10 of whom had abdominal pain and neurogenic or myogenic pseudoobstruction disclosed by manometry. In another 4 patients, slow transit and pain prevailed in conjunction with normal manometric findings. Rapid transit and diarrhoea was found in 3 patients with various abberations on manometry. Of the remaining patients, 4 had slow transit and diarrhoea with intestinal neuropathy and pseudoobstruction, and 2 had slow transit along with endocrinopathies (diabetes, pituitary insufficiency).

Common krait (Bungarus caeruleus) is the deadliest snake found commonly in the dry zone of Sri Lanka. In Anuradhapura, 210 farmers bitten by the common krait over a three year period were investigated prospectively from 1 January 1996. The sex ratio was equal, 110 (52%) patients were in the age group 10-30 years. One hundred and one (48%) patients were severely envenomed and needed mechanical ventilation from 12 hours to 29 days (mode two days). The bite occurred at night while the victims were asleep on the floor. In 99 (47%) situations killed specimens were available for identification. The cardinal symptom was abdominal pain developing within hours of the bite. Alteration in the level of consciousness was observed in 150 (71%) patients: drowsy in 91 (43%), semiconscious in 24 (11%), and deep coma in 35 (17%). Autonomic disturbances included transient hypertension, tachycardia, lacrimation, sweating, and salivation. These manifested in 139 (66%) patients with moderate to severe envenomation. One hundred and forty nine (71%) had hypokalaemia and 105 (50%) metabolic acidosis, anterograde memory loss in 84 (40%), and delayed neuropathy in 38 (22%) patients. Polyvalent antivenom had no significant benefit (t = 0.5) in reversing respiratory paralysis and preventing delayed neurological complications. Sixteen (7.6%) patients died and a submucosal haemorrhage in the stomach was seen at necropsy in three cases. Mortality could be minimised with early and free access to mechanical ventilation.

We report a case of acute intermittent porphyria (AIP) in a 45-year-old woman. Her first attack occurred at the age of 38. Because of escalating cyclical premenstrual attacks, the following 2 years, depletion of the endogenous sex hormone was considered as haeme arginate treatment proved insufficient. Gonadotropin releasing hormone agonist treatment with low-dose oestradiol add back was quite successful initially but was abandoned after 18 months when progesterone add back precipitated a severe attack. Following hysterectomy and oophorectomy at age 42 and oestradiol add back, a remarkable monthly regularity of attacks ensured periodically but with milder symptoms. Two years after surgery, preceded by six attack-free months, a puzzling symptom-shift occurred, from abdominal pain, back and thigh pain during the attacks, to solely severe distal extensor paresis in the arms. Haeme arginate treatment interrupted the progress of the paresis almost immediately and motor function improved considerably up to the 9-month follow-up. Electrophysiological examination revealed only motor neuropathy, consistent with axonal degeneration. Subsequently the symptoms changed yet again, to sensory disturbances with numbness and dysesthesia as the primary expression followed by rather mild abdominal pain. However, cyclical attacks occurred, despite absence of endogenous ovarial hormone production, possibly attributable to impaired oestrogen metabolism in the liver, or adrenal oestrogen production. Treatment comprising oophorectomy, low-dose oestradiol add back and haeme arginate infusion for 2 days on the appearance of early AIP symptoms is now quite successful affording improvement in life quality.

Gastrointestinal symptoms such as nausea and vomiting, heartburn, abdominal pain, diarrhoea, constipation and faecal incontinence are common in patients with diabetes. Diabetes gastroenteropathy is a clinically relevant problem. In addition to the increased morbidity it causes, it results in severely impaired metabolic control, which in turn increases the risk of hyper-/hypoglycaemia. Moreover, the poorly controlled blood glucose level increases the risk of secondary diabetes complications, namely, retinopathy, nephropathy, neuropathy and cardiovascular affection. Gastrointestinal symptoms may also cause malnutrition in patients with diabetes, which, together with the disturbed immune defence in diabetes, may cause intercurrent infections. Gastrointestinal symptoms in patients with diabetes are attributed to disturbed gastrointestinal motility. Gastrointestinal dysmotility in diabetes is believed to be caused by autonomic neuropathy and/or hyperglycaemia. The neuroendocrine system of the gut secretes peptides/amines that play an important role in regulating gastrointestinal motility. It is conceivable, therefore, to assume that a disturbance in this regulatory system may contribute to the pathogenesis of gastrointestinal complications in diabetes. The present review gives an updated overview of the abnormalities in the gastrointestinal neuroendocrine system in diabetes, speculates upon the possible role of these abnormalities in the pathogenesis of diabetes gastroenteropathy and, finally, predicts the possible clinical implications of these findings.

Acute intermittent porphyria (AIP), an inborn error of metabolism, results from the deficient activity of the third enzyme in the heme biosynthetic pathway, porphobilinogen deaminase (PBGD). Clinical symptoms of this autosomal dominant hepatic porphyria include episodic acute attacks of abdominal pain, neuropathy, and psychiatric disturbances. Current therapy based on intravenous heme administration is palliative and there is no way to prevent the attacks. Thus, efforts are focused on methods to replace the deficient activity in the liver to prevent the acute attacks of this hepatic porphyria. Here we explore the efficiency of a non-viral gene delivery to obtain PBGD expression in the liver of AIP transgenic mice. Four vectors were evaluated: naked DNA and DNA complexed to liposomes, polyethylenimine (PEI), and PEI-galactose, using a luciferase construct as reporter gene. The vectors were administered intravenously or directly into the portal vein with transient blood flow blockage. After tail vein injection of the DNA complexes, the liposome vector had the highest luciferase expression in lung and less in liver. When injected into the portal vein, the naked DNA had considerably higher hepatic reporter gene expression; 100 microg of naked DNA had the highest hepatic luciferase expression 24h after portal vein injection. When these vectors were used to deliver the PBGD gene into the AIP mouse model no enhancement of the endogenous PBGD activity in liver was detectable, despite the presence of the PBGD-plasmids as verified by PCR. Thus, more efficient non-viral vectors are needed to express sufficient PBGD activity over the endogenous hepatic level (approximately 30% of normal) in this murine system.

Acute metabolic decompensation of diabetes, hypoglycemia and gastrointestinal tract disease are often connected. Hyperglycemic crisis can be induced by an infectious disease of the gastrointestinal tract, ulcerative disease, gall bladder disease, pancreas disease, and gastrointestinal tract tumours. It can result from diabetic visceral neuropathy manifested especially by impaired patency of the gastrointestinal tract. Metabolic decompensation of diabetes is often accompanied by gastrointestinal symptoms and abnormal laboratory findings. Some of them (especially abdominal pain and increased levels of amylases in serum) can evoke diagnostic and therapeutic hesitation. Insufficient nutrition as a result of gastrointestinal tract disease or adverse reaction to drugs used for its treatment can induce both metabolic decompensation and hypoglycemia.
