The branch retinal vein occlusion is the second most common retinal vascular disease after diabetic retinopathy. Complications such as macular edema, retinal neovascularization, vitreous hemorrhage, epiretinal membrane may be associated. But, the retinal detachment may occur rarely in BRVO patients. We studied the clinical features of retinal detachment associated with branch retinal vein occlusion. We reviewed the medical records of 15 retinal detachment patients associated with branch retinal vein occlusion. Mean age was 54.7 years old and 10 patients(66.7%) were female. Hypertension was associated in 13cases(86.7%). The duration between the development of BRVO and the development of retinal detachment was shorter than 4 years in all cases and shorter than 2 years in 9 cases(60.0%). Retinal break was identified in 14 cases(93.3%), among which 13 cases(92.2%) were located inside the lesion of branch vein occlusion. The epiretinal membrane was frequently combined 8 cases(53.3%). The preoperative laser photocoagulation was done in 4 cases(26.7%). The primary surgical procedures included scleral buckling in 8 cases(53.3%), pars plana vitrectomy in 6 cases(40.0%), and scleral buckling with pars plana vitrectomy in 1 case(6.7%). Three cases(20.0%) required reoperations. The postoperative complications included the progression of cataract in 6 cases(40.0%), iatrogenic retinal tear in 3 cases(20.0%), epiretinal membrane in 2 cases(13.3%), and proliferative vitreoretinopathy in 1 case(6.7%). The anatomic retinal reattachment was achieved in 14 cases(93.5%) and the visual recovery in 11 cases(73.3%).

This study was done on the 209 expired patients among 2,480 pediatric intensive care patients who were admitted to pediatric intensive care unit (PICU), Seoul National University Children's Hospital (SNUCH) from 1986 to 1988. The overall fatality rates were 7.5%, 8.3%and 9.3%in 1986, 1987 and 1988 respectively. The fatality rate in cardiothoracic surgery increased year by year, which were 6.0%, 6.2 %and 9.7% in 1986, 1987 and 1988. The abrupt rise of fatality rate in cardiothoracic surgery in 1986 might be related to the increase of total number of complex heart diseases which required more urgent surgical interventions in their early ages. The fatality rate was inversely proportional to age. Moreover, patients under 1 month and between 1 month and 1 year showed 16.0% and 12.1% of fatality rate respectively. The patients staying for more than 8 days showed the highest fatality rate (13.8%), which might be partially related to increased incidence of complications. We conclude that fatality rate in PICU will not be easily decreased due to increased number of complex congenital heart diseases and medical insurance in Korea.

BACKGROUND: In recent years, the incidence of extended-spectrum beta-lactamase (ESBL) producing Klebsiella has been steadily increased, and the newer species K. planticola and K terrigena, formerly regarded as nonpathogen, have been reported with astonishing frequency from human infectious processes by some investigators. The aim of this study is to elucidate the isolation rate and antimicrobial susceptibility of recent clinical Klebsiella isolates. METHOD: For the clinical Klebsiella isolates during the period of June 1999 to May 2000, isolation frequency of Klebsiella species by specimen, departments, age, and sex were analyzed. And antimicrobial susceptibilities were also analyzed. RESULT: Isolation rate of Klebsiella in order of decreasing frequency were K. pneumoniae (74:7%), K. oxytoca (12.1%), K. ozaenae(1.7%), K. planticola(1.0%), K. terngena(0.9%), and K, ornithinolytica (0.7%), respectively. K. rhinoscleromatis was not isolated. Compared with outpatients, increase of resistance rates of inpatients's Klebsiella isolates were 10% in ciprofloxacin, 15% in cefoperazone/sulbactam, and the others were ranged from 24% to 31%. Isolation rate of ESBL producing K. pneumoniae by double disk (DD) synergy test was 41%, and detection rates by antimicrobial agents were as follows: cefotaxime (95%), aztreonam (58%), and ceftriaxone (37%). Antimicrobial susceptibility rate with the exception of ampicillin and imipenem decreased from the range of 81%-96% on admission day to 29-62% after one week on admission. CONCLUSION: The isolation rates of K. planticola and K. terrigena were less than 1%. The proportion of ESBL producing K. pneumoniae was 41 %. And the vast majority of multidrug resistant Klebsiella including ESBL producing strains are acquired by hospitalization.

Animal study was performed to determine the changes in rat lung permeability in hyperoxic condition. 3 groups of rats (n=8 each) were exposed to 100% oxygen for 24 hr(group 2), 48 hr(group 3) and 72 hr(group 4), respectively, and compared with control (group 1 at room air, n=8). The time course of development of solute flux was evaluated by the clearance of 99mTc-labeled diethylenetriamine pentaacetate ( 99mTc-DTPA) from the lung, Afterwards, bronchoalveolar lavage (BAL) was performed to measure the concentration of albumin and determine the evidence of cell injury and inflammation in lung. BAL fluids were analyzed to determine several markers of cell injury and inflammation including total and differential cell counts, lactate dehydrogenase (LD), alkaline phosphatase (ALP), extracellular potassium (K+) and globulin (total protein minus albumin). 99mTc-DTPA clearance was significantly increased by exposure for 48 hours of hyperoxia. Albumin concentration ratio (BAL albumin concentration divided by serum albumin concentration) was increased sharply after 48 hr. Significant changes in WBC counts and differential counts were not found until 48 hr of hyperoxia. Elevated LD concentration was observed at 48 hr and thereafter, and ALP, K+, and globulin concentration ratio (BAL globulin /serum globulin) was significantly high only in group 4. Mortality was not observed until 72 hr when 3 of 8 rats were dead. It is concluded that significant 99mTc-DTPA clearance, and cellular and biochemical findings of BAL could not be observed until 48 hr in rats exposed to 100 % oxygen.

Amyloidosis of the prostate is a rare disease. With more patients undergoing biopsy of the prostate to exclude malignancy, the likelihood of identifying primary or secondary amyloidosis of the prostate has increased. We report a case of amyloidosis of the prostate in a 70-year-old man. The diagnosis was made from prostatic biopsy. Later, he was diagnosed with prostatic adenocarcinoma after transurethral resection of the prostate due to persistent lower urinary tract symptoms.

In the management of postoperative fluid collection, the conventional percutaneous drainage method can be employed. Because of abdominal incisions and various types of surgical drains and/or T-tubes, the application of this method is not always easy, however. We inserted a drainage catheter through a pre-existing percutaneous track formed by a surgical drain located adjacent to the site of abnormal fluid collection. There was no need to remove the drain nor make an additional puncture in the abdominal wall. A dilator was inserted along the drain, and a guide wire was used to negotiate its intraperitoneal track and readch the accumulated fluid. The procedure was simple and safe. We briefly deseribe our experience of this modified percutaneous drainage technique, as used in three cases involving postoperative fluid collection.

BACKGROUND: Conventional correction of malunioned zygoma requires complete regional exposure through a bicoronal flap combined with a lower eyelid incision and an upper buccal sulcus incision. However, there are many potential complications following bicoronal incisions, such as infection, hematoma, alopecia, scarring and nerve injury. We have adopted a zygomaticofrontal suture osteotomy technique using transconjunctival incision with lateral paracanthal extension. We performed a retrospective review of clinical cases underwent correction of malunioned zygoma with the approach to evaluate outcomes following this method. METHODS: Between June 2009 and September 2015, corrective osteotomies were performed in 14 patients with malunioned zygoma by a single surgeon. All 14 patients received both upper gingivobuccal and transconjunctival incisions with lateral paracanthal extension. The mean interval from injury to operation was 16 months (range, 12 months to 4 years), and the mean follow-up was 1 year (range, 4 months to 3 years). RESULTS: Our surgical approach technique allowed excellent access to the infraorbital rim, orbital floor, zygomaticofrontal suture and anterior surface of the maxilla. Of the 14 patients, only 1 patient suffered a complication—oral wound dehiscence. Among the 6 patients who received infraorbital nerve decompression, numbness was gradually relieved in 4 patients. Two patients continued to experience persistent numbness. CONCLUSION: Transconjunctival incision with lateral paracanthal extension combined with upper gingivobuccal sulcus incision offers excellent exposure of the zygoma-orbit complex, and could be a valid alternative to the bicoronal approach for osteotomy of malunioned zygoma.
