Analysis of Surgical Outcomes of Diverticular Disease of the Colon

We analyzed retrospectively the surgical outcomes of diverticular diseases of the colon at the surgical division of Fukuyama Medical Center. Data were collected from 39 patients who underwent surgery for diverticular disease at Fukuyama Medical Center. Thirty-nine patients were admitted between 2005 and 2010. The mean age of the 39 patients was 63.6 years. The collected data included patient demographics, patient history, type of surgery and complications. Patients were divided into 2 groups, Elective vs. Emergent group, right vs. left colon group and laparotomy vs. laparoscopic approach. Multivariate analysis of the logistic model of morbidity revealed a significantly higher rate in the left colon and the Cox proportional hazards model clearly showed fewer postoperative hospital days with the laparoscopic approach. Surgical procedures should be decided in reference to the particular clinical and pathological features of diverticular disease to gain an acceptable morbidity and mortality rates

Two cases of lymphoepithelial cyst of the pancreas

A 35-year-old man was found to have a cystic mass in the pancreatic body on a routine health examination ; high serum CA19-9 was also detected. The enucleated cyst was diagnosed as a lymphoepithelial cyst (LEC). A 74-year-old man found to have a cystic mass in the pancreatic head by computer tomography as well as high serum CA19-9 was suspected of a cystic neoplasm of the pancreas (IPMN), and pylorus-preserving pancreaticoduodenectomy (PPPD) was performed. Pathologically, the cyst was found to be LEC. It is often difficult to diagnose pancreatic cyst as LEC preoperatively. Care should be taken not to do over-surgery for benign disease LEC

Occurrence and age composition of Paralabidocera antarctica (Calanoida, Copepoda) under the fast ice near Syowa Station, Antarctica

A year-round observation of Paralabidocera antarctica, an endemic copepod in the Antarctic, was done near Syowa Station, Antarctica, from January 1982 to January 1983. P. antarctica occurred in the spring to the summer seasons between late September and late January and was very abundant while the phytoplankton biomass was high. The P. antarctica population which appeared in late September to early November was composed of copepodite stages I, II and III. Developmental stage progressed from middle November to middle December. In middle December, the P. antarctica population consisted mostly of adults with a few individuals of copepodite stage V. After late December it was occupied by adults only, while adult females were bearing the spermatophores commonly. P. antarctica seemed to have one generation in a year

Seasonal change of chlorophyll a under fast ice in Lutzow-Holm Bay, Antarctica

Chlorophyll α concentration in water column under the Antarctic fast ice was measured at five stations (10-675m depths) near Syowa Station (69°00′S, 39°35′E) for the period of 13 months from January 1982 to January 1983. High chlorophyll α concentrations were seen between December and March, while peaks were observed in late January. Maximum concentration was 11.30mg chl. α/m^3. During four months of the austral summer, a rapid increase of chlorophyll α was observed in late January. This phenomenon seemed to be caused by a slight increase of temperature (>-1.73℃) and a slight decrease of salinity (<34.15). Average chlorophyll α stock in water columns was 1.05-6.72mg/m^3,at least one order of magnitude higher than that reported from the Antarctic open water
