The International Health Regulations (IHR) (2005) require World Health Organization Member States to notify events fulfilling two of four criteria: (1) serious public health impact; (2) unusual or unexpected event; (3) significant risk of international spread; or (4) significant risk of international travel or trade restrictions. In-flight transmission of infections like severe acute respiratory syndrome is well documented. With the enormous amount of air travel today, the risk of increasing in-flight transmission and subsequent international spread of infections are increasing. Prompt notification and information sharing under the IHR mechanism is critical for effective contact tracing and prompt control measures. We report on a case of in-flight exposure to an infection with significant public health risks that was successfully resolved using IHR (2005) guidelines.

PURPOSE: Peptide YY is composed of 36 amino acids, and its functions are suppression of gastric acid secretion, delay of gastric emptying, increase of intestinal motility, inhibition of pancreatic exocrine secretion, and enhanced postprandial colonic absorption of water and electrolyte. PYY is released from PYY cells, which are mainly distributed in the ileum and colon, in response to the presence of intraluminal lipids. This study was designed to determine the regional distribution of PYY in the normal human ileum, colon, rectum, and anal canal by studying mucosal concentrations. METHODS: Fresh tissues were obtained from specimens of segmental resections of the small bowel, colectomies, ileostomies, and abdominoperineal resections for the management of colonic or rectal carcinomas or benign diseases of the bowel. Only specimens devoid of advanced luminal obstruction were included. Mucosa was separately recruited by microdissection of frozen sections. Radioimmunoassays were performed using the methods of Adrian et al. RESULTS: The concentration of PYY was highest at 25 cm proximal to the ileocecal valve in the ileum (307.6 pmol/ g) and in the upper rectum at the colon (653.1 pmol/g). The concentration of PYY was 27.3 pmol/g in the anal canal distal to the dentate line. A clear differential distribution of PYY was shown in the ileum and colon. CONCLUSIONS: This study showed PYY was present in large amounts in the mucosa of the ileum and colon, with high concentrations in locations 25 cm proximal to ileocecal valve and in the upper rectum, respectively. The trend of regional differences in PYY in the colonic mucosa probably reflects local differences in functions, such as absorption and storage. Also, the peak concentration in the ileum at 25 cm proximal to ileocecel valve suggests that this region is the most abundant production site of PYY in the ileum.

A rare case of spontaneous subarachnoid hemorrhage from newly developed cerebral aneurysm in glioblastoma patient is presented. A 57-year-old man was presented with headache and memory impairment. On the magnetic resonance image and the magnetic resonance angiography, a large enhancing mass was found at right frontal subcortex and intracranial aneurysm was not found. The mass was removed subtotally and revealed as glioblastoma. He took concurrent PCV chemotherapy and radiation therapy, but the mass recurred one month later after radiotherapy. He was then treated with temozolomide for 7 cycles. Three months after the completion of temozolomide therapy, he suffered from a subarachnoid hemorrhage due to a rupture of a small de novo aneurysm at distal anterior cerebral artery. He underwent an aneurysm clipping and discharged without neurologic complication.

PURPOSE: Primary colonic lymphomas are very rare disorders and the most common location of a colonic lymphoma is the cecum. However, the prognosis for patients with a primary cecal lymphoma is not well understood clear. This study was undertaken to assess the prognosis for patients with a primary cecal lymphoma. METHODS: A retrospective analysis of our patients, who were categorized into two groups, cecal lymphoma (10 cases) and non-cecal lymphoma (10 cases), was performed from January 1985 to December 2001. The prognostic factors were analyzed. RESULTS: The most common presenting symptoms and signs of cecal lymphomas were abdominal pain (80.0%), nausea/ vomiting (80.0%), and abdominal mass (40.0%). The preoperative biopsy- proven diagnostic rate of cecal lymphoma was 10.0%. The mean size of cecal lymphomas was significantly smaller than that of non-cecal lymphomas (6.2 cm vs. 10.0 cm). Histologically, 9 (90.0%) of the primary cecal lymphomas were classified as intermediate-grade lymphoas, and 1 (10.0%) as a high-grade lymphoma. three (30.0%) of the cecal lymphomas were Stage IE, 5 (50.0%) were Stage IIE1, and 2 (20.0%) were Stage IVE. Tumor resection and chemotherapy was used for 8 (80.0%) of the cecal lymphomas. Two regimens of chemotherapy were used: CHEP-Bleo (cyclophosphamide, doxorubicin, and epirubicin, prednisone, and bleomycin) and COP-BLAM (cyclophosphamide, vincristine, prednisone, bleomycin, doxorubicin, procarbazine). The median survival time for patients with a cecal lymphoma was 56 months, but that survival time was not significantly different from the survival time for patients with non-cecal lymphoma. CONCLUSIONS: The prognosis for patients with a primary cecal lymphoma appears to be similar to that for patients with a non-cecal lymphoma. However, the number cases in our study was very small, the more cases are needed to establish a general prognosis for patients with a primary cecal lymphoma.

PURPOSE: Although the current trend is to use a sphincter- saving operation (SSO) for management of distal rectal cancer, an abdominoperineal resection (APR) is widely performed in low rectal cancers. Numerous studies have reported that lateral margin is an important prognostic factor for recurrence in low rectal cancers. In regard to curability, the presence of an involved lateral margin after a resection of a low rectal cancer is currently accepted as being an indicator of a non-curative resection. Indeed, the higher rate of positive lateral margins after APRs than after a SSO may explain the inferior oncologic outcomes of APRs. Therefore, the purpose of this study was to analyse the oncologic results of 'curative' APRs and SSOs. METHODS: This retrospective study included 111 patients who had undergone surgical treatment between 1995 and 2000 with either an APR (n=65) or a SSO (n=46). The oncological outcomes of the patients who had undergone an APR were compared with those of the patients who had undergone a SSO. Univariate and multivariate analyses were used to evaluate the data. RESULTS: The distal resection margin and the mean distance between the tumor low margin and the dentate line were significantly different between the two groups. However, the disease-free and the overall survivals, as well as the frequency of local recurrence and that of overall recurrence, after rectal excision did not differ between the two groups. Multivariate analyses showed that the method of surgery was not a significant independent factor in predicting either disease-free survival or overall survival. However, advanced stage III was a significant predictor of outcome after the operation. CONCLUSIONS: The type of operation did not affect the oncological outcome after a 'curative' resection for distal rectal cancer.

Erythromelalgia is a rare clinical condition of unknown etiology characterized by severe burning pain in the distal limbs. It can be accompanied by pronounced erythema and increased skin temperature precipitated by heat or activity and can be improved by cooling the affected part. It can be divided into two categories, primary, which begins spontaneously at any age, and secondary, which is infrequently associated with diabetes mellitus. However, the significance of this association is little known. We report a rare case of intractable erythromelalgia in an adolescent with diabetes mellitus.

Hemangioblastoma is uncommon, accounting for 1 to 2.5% of all primary neoplasms of the central nervous system. Ten to 20% of hemangioblastomas occur as part of Von Hippel-Lindau disease(VHL). Multiple hemangioblastomas are seen only with VHL and these are seen in up to half of VHL-associated hemangioblastomas. We have treated two cases of multiple hemangioblastomas associated with VHL disease in a family, sister(case I, 48/female) and her brother(case II, 41/male). Both patients had renal and pancreatic cysts in addition to CNS hemangioblastomas. Their hemangioblastomas were removed totally, and then their neurological symptoms had Improved. With a review of the literature, the authors present a family of VHL-associated multiple hemangioblastomas.

Ethambutol is commonly used as a first-line drug for the treatment of tuberculosis. The most serious adverse effect of ethambutol therapy is optic neuropathy. However, ethambutol-induced acute kidney injury is extremely rare. We report herein a case of acute kidney injury secondary to ethambutol-associated acute interstitial nephritis. A 65-year-old man with pulmonary tuberculosis presented with a > 7-day history of nausea and vomiting. He had begun antituberculosis medications including ethambutol 3 weeks previously. His laboratory findings showed elevated blood urea nitrogen and serum creatinine levels (32.6 and 3.6 mg/dL, respectively). Examination of percutaneous renal biopsy specimens showed diffuse interstitial mononuclear cell infiltration with mild interstitial edema. The patient was treated by cessation of ethambutol and supportive care. His renal function completely recovered (creatinine, 1.1 mg/dL) and his clinical symptoms improved.
