The glucagonoma syndrome is a rare disease in which a typical skin disorder, necrolytic migratory erythema, is often one of the first presenting symptoms. Weight loss and diabetes mellitus are two other prevalent characteristics of this syndrome. Necrolytic migratory erythema belongs to the recently recognized family of deficiency dermatoses of which zinc deficiency, necrolytic acral erythema and pellagra are also members. It is typically characterized on skin biopsies by necrolysis of the upper epidermis with vacuolated keratinocytes. In persistent hyperglucagonemia, excessive stimulation of basic metabolic pathways results in diabetes mellitus at the expense of tissue glycogen stores, and muscle and fat mass. Multiple (essential) nutrient and vitamin B deficiencies develop, which contribute to the dermatosis. In addition, glucagonomas may produce various other products, like pancreatic polypeptide, that add to the catabolic effects of glucagon.

Many diabetic patients carry a portable self-monitoring of blood glucose (SMBG)-analyzer in order to collect their own blood and examine their glucose levels; this allows them to determine such factors as insulin dose, diet and exercise to stay healthy. However, the test causes physical and mental stress for the subjects. The authors aim to develop a semi-invasive blood-collecting needle which does not need a power source for the pump mechanism. In this study, we fabricated a capillary action needle that can collect the blood sample automatically. A blood-collecting needle was fabricated from 25 gage sized medical needle (diameter of 0.5 mm, stainless steel) by cutting process, and it had a half-opened crevice in the tip. In order to evaluate the physical characteristics of the blood-collecting needle, the relationship between the size and suction time and/or suction volume were measured using an isotonic sodium chloride solution, whole rabbit blood, and whole human blood with anticoagulant. Next, in order to evaluate the degree of invasion, the diameters of erythema in auricles of rabbits were observed for 2 days using a CCD camera-type microscope. The mean suction time of the isotonic sodium chloride solution and the whole rabbit blood were 1.5 s (n = 10) and 9.0 s (n = 5), respectively. Selection of a suitable size of the blood-collecting needle enabled the collection of 0.1 microL of whole human blood in 10 s. Moreover, it was shown, by comparing the observed diameter of the erythema, that the invasiveness of the blood-collecting needle was smaller than for commercial needles of the equal diameter. It became clear that this fulfils the fundamental functions of a semi-invasive blood-collecting needle.

A 24-year-old man was admitted to our hospital because of liver dysfunction. He had been diagnosed as having psoriasis vulgaris at 18 years of age. Physical examination demonstrated obesity, general erythema, and hepatomegaly. Laboratory data revealed elevated serum levels of aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, and glucose. A histological examination of the liver revealed macrovesicular fatty change and infiltration of inflammatory cells, including lymphocytes and polymorphonuclear cells, within the liver lobules. Pericentral fibrosis and pericellular fibrosis were also recognized. He was diagnosed as having nonalcoholic steatohepatitis (NASH), based on the fact that he had no habit of drinking alcohol, as well as psoriasis vulgaris and diabetes mellitus. We herein report a very rare case of NASH associated with psoriasis vulgaris.

A 44-year-old woman was diagnosed with type II diabetes in 1998 and 1 year later she developed necrolytic migratory erythema, which is a specific skin lesion of glucagonoma. During the clinical investigation, a nodular 6 cm mass in the distal pancreatic region and multiple cystic liver metastases were found. She was operated on, and glucagonoma was detected and the long-acting, repeatable, octreotide treatment was started. 3 years after resection of a pancreatic glucagonoma she presented to a hospital emergency department with diabetic ketoacidosis. Hepatic multiple cystic metastases were visualized by computed tomography. During hospitalization she developed severe pulmonary embolism and deep-venous thrombosis of the lower extremities. Indium-labeled octeotide scintigraphy showed multiple cystic lesions in the liver with additional lesions in the iliocecal region, which had not been visualized by computed tomography. Despite somatostatin therapy the tumor had expanded in the liver. Arterial chemoembolization was performed but 6 months later she died.

Glucagonoma is a very rare endocrine pancreatic tumor. At diagnosis, most glucagonomas are malignant and often metastatic. Suspicion of glucagonoma is based on characteristic presentations known as "glucagonoma syndrome". Glucagonoma is often found in the pancreatic body and/or tail and is usually large enough to be localized by computed tomography. We report a case of diffuse glucagonoma necrolytic migratory erythema (NME) in a 45-year-old man with mild diabetes mellitus, mild anemia, and weight loss over 1.5 years. Diffused enlarged pancreas was noted on abdominal ultrasonography incidentally during a routine health check-up. The levels of carcinoembryonic antigen and carbohydrate antigen 19-9 were within normal limits. No enlarged lymph node or extrapancreatic tumor mass was found by several imaging studies. Total pancreatectomy was performed, and the pathology revealed glucagon-producing islet cells and intrapancreatic vascular emboli of tumor cells. He died due to internal bleeding and sepsis after surgery. Presentation of diffuse malignant glucagonoma with tumor emboli but no metastasis or NME is unusual.

It would appear that a significant number of cardiologists are unaware that skin injuries ranging from erythema to telangiectasia or even dermal necrosis can be caused by the procedures they perform. Conditions that have been reported to be associated with radiation-induced skin injuries include: the high values of the exposure factors required with thick patients; prolonged or multiple procedures; elevated radiosensitivity of some patients (ataxia telangiectasia); connective tissue disease and diabetes mellitus. The total number of reported severe injuries worldwide so far is 100-200, or over 200 when all degrees of skin injuries are included, but the real number may be substantially larger since initial symptoms often appear only weeks after the procedure and the cardiologist may not be notified, unless a procedure for systematic follow up is in place. Besides skin injuries, patients-more so, the younger ones-incur a risk of radiation-induced cancer at some stage in the future. Experience shows that, with awareness of radiation safety aspects, proper equipment performance, the use of proper techniques, and the monitoring of patient doses, severe skin injuries should not occur in patients undergoing 5-10 PTCA-s. However, for those patients whose radiation doses approach the thresholds for radiation injuries a systematic follow up is required. These issues are addressed here.

Bergenia ciliata was subjected to bioactivity analysis. The records of these investigations are described in this communication. A study made on the bioactivity analysis of medicinal herb Bergenia ciliata, which in folkloric medicine is used to cure hypoglycemic activity. A battery of assays was performed on different extracts of Bergenia ciliata which include hypoglycemic activities, toxic evaluations such as acute systemic and intracutaneous toxicity as well hemolysis test. Bergenia ciliata has been employed in folklore medicine to treat symptoms of diabetes mellitus. All the extracts except chloroform extract of root and leaves of Bergenia ciliata were found to possess hypoglycemic activity in Streptozotocin (STZ) treated rats. Therefore the plant can be classified as hypoglycemic, hypoglycemic activity in experimental diabetes ranging from 40-70% of its onset to reduce blood glucose level. The toxicological investigations of Bergenia ciliata with particular reference to acute systematic toxicity and intracutaneous toxicity in experimental animals displayed that it elicit severe toxicity. The symptoms of toxicity in intracutaneous test showed erythema and edema whereas assessment of acute systemic toxicity frequently observed breathing problem and initiations of diarrhea with blood in stool of experimental model and caused gastero-intestinal syndrome. Bergenia ciliata can produce toxicity suggesting a role in certain diseases. It is therefore, premature to speculate about mechanism of effect until toxin(s) is unequivocally identified. The hemolysis test on the extract of Bergenia ciliata was almost devoid of activity.

We present a 61-year-old man with a 2-year history of persistent disseminated, psoriasiform annular pruritic lesions, acrodermatitis, weight loss, anemia and diabetes. Histopathology of the affected skin showed nonspecific subacute psoriasiform dermatitis. The computed tomographic scan of the abdomen revealed multiple hepatic tumors. Histopathological examination of ultrasound-guided needle biopsy from a hepatic lesion demonstrated a neuroendocrine tumor. Somatostatin-receptor scintigraphy with radio-labelled octreotide confirmed the likelihood of the neuroendocrine nature of the hepatic tumors and excluded the presence of other such lesions throughout the rest of the body, including the pancreas. The serum glucagon level was markedly increased. The diagnosis of necrolytic migratory erythema associated with hyperglucagonemia and neuroendocrine hepatic tumors was made and therapy with the long-acting somatostatin analogue octreotide was started. The skin changes resolved after the initiation of therapy, but no improvement of other symptoms was observed. Having reached the final stage of the disease, which was further complicated by congestive heart failure, the patient died one year later. As no autopsy was performed, we were unable to establish whether the hepatic tumors represented a metastatic process of previously undetected pancreatic glucagonoma or if they were extra-pancreatic glucagon-secreting tumors. The correct diagnosis of necrolytic migratory erythema is important, since it might be the clue for early detection of glucagonoma or of extra-pancreatic glucagon-secreting tumors.
