BACKGROUND:Chylous ascites(CA) following pancreatico-duodenectomy(PD) is a rare complication secondary to disruption of the lymphatics during extended retroperitoneal lymph node dissection. The majority of cases do not develop CA,possibly due to patency of the proximal thoracic duct and good collaterals. CA may be due to a consequence of occult obstruction of the proximal thoracic duct by malignant infiltration or tumor embolus. This study was to report the incidence of CA and its outcomes of management. METHODS:A retrospective search of our liver database was performed using the 'pancreatico-duodenectomy','chylous ascites' from January 2000 to December 2005. The medical records of CA patients and their management and outcome were reviewed. RESULTS:In 138 patients who had undergone PD in our centre for pancreatic malignancy,3 were identified with CA and managed by abdominal paracentesis. CA resolved in 2 patients with low fat medium chain triglyceride diet alone and 1 patient had total parenteral nutrition(TPN) for persistent CA. Resolution of CA occurred in these 3 patients at a median follow-up of 4 weeks(range 4-12 weeks). Histologically,resected specimen confirmed pancreatic adenocarcinoma in all the patients. Two patients developed loco-regional recurrences at a median follow up of 8 months(range 6-10 months). And the other was currently disease free at a 10-month follow up. CONCLUSIONS:CA as an uncommon postoperative complication requires frequent paracentesis,prolonged hospital stay,and delayed adjuvant chemotherapy. CA istreated with low fat medium chain triglyceride diet or occasionally TPN is required.

BACKGROUND:Neuroendocrine tumors(NETs)arising in the biliary tree are extremely rare,and 37 cases were identified in the English literature. METHODS:A well-differentiated NET was found arising from the junction of the cystic and common hepatic ducts, in a 51-year-old male presenting with pedal edema and weight loss with abnormal liver enzymes and a normal serum bilirubin *** mass was seen on radiological imaging and biopsy of the liver was suggestive of an early cholangiopathy.A bile leak complicating the liver biopsy led to an ERCP that demonstrated a filling defect suggestive of a mass in the common bile duct(CBD). RESULTS:He underwent a successful excision of the tumor with a Roux-en-Y *** diagnosis of NET was made on histological and immunohistochemical analysis of the resected *** remains well and disease free 22 months after surgery. CONCLUSIONS:Recognition of biliary NET continues to be a challenge and an increased awareness of these tumors in rare sites will result in optimal management of these tumors.

In the United Kingdom, newborn assessment incorporates a screening eye examination for any structural abnormalities, observation of neonate’s visual behaviour and direct ophthalmoscopy examination looking for red reflex. Early identification and immediate management of eye related pathologies should commence soon after birth as early diagnosis and prompt intervention may have significant impact on the prognosis for many potentially blinding but treatable disorders such as congenital cataracts and retinoblastoma. If left undetected and untreated, such problems may potentially lead to irreversible damage to the vision which persists into adulthood resulting in lack of self-confidence together with difficulties in educational attainment and job opportunities.

BACKGROUND: Transcatheter arterial chemoembolization (TACE) is a recommended first line therapy for unresectable hepatocellular carcinoma (HCC). Serious complications such as neutropenic sepsis and hepatic decompensation are well known, but rupture of HCC following TACE is a rare and potentially fatal complication. The aim of this study was to identify the incidence of ruptured HCC following TACE and the associated risk factors. METHODS: A retrospective analysis was performed using our liver database with 'chemoembolization', 'ruptured HCC' covering the patients who received chemoembolization from January 1995 to December 2005. There were no exclusions. RESULTS: A total of 294 patients received chemoemboliza- tion in 530 sessions during the 10-year period. Of these, 2 ruptured following treatment (incidence 0.68%). The mean age was 65 years and the interval between the treatment and rupture was 2 and 24 days. The common factors were male sex, large tumor size (range 11-13 cm), and exophytic tumor growth. One patient died 2 days after rupture with hepatic decompensation while the second is alive after a 6-month follow up without tumor recurrence. CONCLUSIONS: Ruptured HCC following TACE is a rare but serious complication. Large tumor size, male sex, and exophytic growth of tumor may be predisposing factors for rupture.

Zinc oxide （ZnO） nanorods are prepared using equimolar solution of zinc nitrate （（Zn（NO3）2） and hexamethylenete- tramine （C6HleN4） by the hydrothermal technique at 80 ~C for 12 h. Epitaxial growth is explored by X-ray diffraction （XRD） patterns, revealing that the ZnO nanorods have a hexagonal （wurtzite） structure. Absorption spectra of ZnO are measured by UV-visible spectrometer. The surface morphology is investigated by field emission scanning electron mi- croscopy （FESEM）. The synthesized ZnO nanorods are used for detecting the 150 ~C hydrogen gas with a concentration over 1000 ppm. The obtained results show a reversible response. The influence of operating temperature on hydrogen gas detecting characteristic of ZnO nanorods is also investigated.
