We have experienced a case of bilateral bacterial endophthalmitis after bilateral elevation of intraocular pressure. This patient suffered from meningitis and bacteremia. The enucleation was performed and histopathologic studies revealed severe inflammary change of the anterior segment. The present report described the relation between clinical signs and histopathologic findings of the metastatic endophthalmitis. We should keep in mind the possibility of the metastatic endophthalmitis in case of acute increase of intraocular pressure.

BACKGROUND: Community-acquired pneumonia (CAP) is more frequent in the elderly and results in higher morbidity and mortality. Korea is undergoing extraordinary demographic change. Elderly patients constitute an even-increasing proportion of the population but there have been few studies on the epidemiological investigation of the CAP in the elderly. The purpose of this study was to characterize the background, etiology, clinical course and outcome of CAP in elderly compared with younger patients. METHODS: During the study period (from 1st January to 31th December 1997), 214 patients with CAP were reviewed with regard to epidemiological, clinical, laboratory and microbiological data. 119 elderly patients (> or =65 years-old of age) were compared with 95 younger patients (<65 years-old of age). The both groups were compared with each others in terms of variables related to CAP. RESULTS: Comparison of epidemiological data between older and younger patients revealed a high prevalence of alcoholics (40% vs 56%), current smoker (33% vs 56%), malignancy (8% vs 24%) in the elderly. In terms of complication and clinical manifestation, shock (1% vs 6%), intubation (6% vs 20%), mechanical ventilation apply (5% vs 18%), respiratory failure (2% vs 12%), dyspnea (26% vs 56%), altered consciousness (0% vs 13%), extrapulmonary symptom (11% vs 18%) and bilateral infiltration (8% vs 20%) showed higher incidence in the elderly than in the younger patients. Causative organisms are identified in 47% (56/119) of elderly patients: those identified most frequently were S. pneumoniae (25%), K. pneumoniae (20%), S. aureus (16%), other Gram-negative bacilli (13%) and H. influenzae (11%). The overall mortality were significantly higher in the elderly patients (24%) than younger patients (5%). Two independent risk factors, those were related to the mortality of the elderly:higher APACHE II score (RR:3.43, 95% CI=1.43~7.21) and requirement of endotracheal tube (RR:4.73; 95% CI=1.72~16.5). CONCLUSION: CAP in the elderly shows more serious clinical and abnormal laboratory features than younger patients. In elderly, S. pneumoniae was the most common causative organism for CAP but other agents, particularly K. pneumoniae was isolated frequently. The severity of illness at initial presentation such as high APACHE II score and requirement of endotracheal tube were the major variables affecting the outcome.

Intussusception in adult is a rare disease and laparotomy is usually considered because of the probability of malignancy. Especially with obstruction symptom or sign, it might be needed emergency operation. This case was a simultaneous development of small bowel intussusception and acute hepatitis A. The patient had abdominal pain and vomiting. Intitial laboratory examination with elevated aminotransferase revealed that the diagnosis was acute hepatitis. As managing acute hepatitis, the abdominal pain was not improved and the patient had tenderness on periumbilical area on physical examination. A jejunal intussusception with a lead point was proved on the abdominal computed tomography scan. Fortunately, symptom of intussusception was relieved while nulli per os (NPO) and intravenous hydration. After recovery of acute hepatitis, laparotomy was done. The lead point was 2.5x3.0 cm sized hamartoma. This was the case that the symptom of intussusception was confused with that of acute hepatitis.

PURPOSE: To describe the HRCT and pathologic findings of squalene-induced lipoid pneumonia in rabbits. MATERIALS AND METHODS: Three ml of squalene was instilled into the trachea between the second and the third tracheal ring in 16 rabbits. Serial HRCT scans were obtained on day 4 (n=8), at 1 week (n=7), 2 weeks (n=1), 4 weeks(n=1), 6 weeks (n=2) and 20 weeks (n=1) after squalene instillation. With sacrifice of the rabbits pathology was reviewed at 1 week (n=3), 4 weeks (n=3), and 6 weeks (n=4) after CT scans. RESULTS: Lipoid pneumonia was induced in 8 rabbits; lesions were distributed mainly in the dependent posterior lung. On serial HRCT scans, airspace consolidation, as seen on an air-bronchogrm, and nodular opacities were early findings; these gradually diminshed and with time were replaced by nodular & linear opacities. Histologically, pulmonary fibrosis appeared one week after squalene instillation and progressed over time. Alveolar septal thickening and cuboidal change of the alveolar lining epithelium were more prominent at week 6. CONCLUSION: The early change of squalene-induced lipoidpneumonia in rabbits is the proliferation of intraalveolar macrophage, which is responsible for air-space consolidation with air-bronchograms on HRCT. Nodular and linear opacities on HRCT are due to the appearance of pulmonary fibrosis one week after squalene instillation, and its subsequent progression.

PURPOSE: To prevent surgical site complications, many plastic surgeons use the so-called “conventional protocol,” which immobilizes the shoulder and upper arm for 1 month after reconstruction. In an effort to improve the shoulder mobility of patients who received immediate breast reconstruction with tissue expander insertion (TEI), we introduced an early rehabilitation protocol with a short-term immobilization period of 2 weeks. This study aims to compare this early rehabilitation exercise program with the conventional protocol and to determine factors affecting shoulder mobility and quality of life of patients after immediate breast reconstruction. METHODS: A total of 115 patients with breast cancer who underwent reconstructive surgery were retrospectively reviewed. For patients who underwent reconstruction before January 2017, the conventional protocol was followed with immobilization of their shoulder for over 4 weeks. Patients who underwent reconstruction after January 2017 were educated to undergo a self-exercise program after a short-term immobilization period of 2 weeks. We compared shoulder mobility, pain, quality of life, and complications at postoperative 1 and 2 months between the groups. RESULTS: Patients who received early rehabilitation showed greater shoulder flexion and abduction range at postoperative 1 month than those who received the conventional protocol. This increased shoulder abduction range continued until postoperative 2 months. There were no significant surgical site problems in both groups during the 2 months of follow-up. CONCLUSION: To enhance the recovery of shoulder mobility, early rehabilitation with a shorter immobilization period should be recommended to patients with breast cancer undergoing reconstruction surgery with TEI.

BACKGROUND/AIMS: Infection with hepatitis B virus (HBV) may result in various conditions. Natural course of HBV infection is influenced by various host immune factors and cytokines play a crucial role in host immune defense. This study was undertaken to investigate the association between HBV persistence and development of hepatocelluar carcinoma (HCC) and single nucleotide polymorphisms (SNPs) of interleukin (IL)-12A. METHODS: Between March 2002 and December 2004, seven hundred thirty Korean patients with HBV infection and 320 healthy individuals who recovered from HBV infection were enrolled. We assessed polymorphisms and haplotype in IL-12A, and the genotype distributions of the HBV clearance and persistence groups were compared in order to investigate the association between HBV persistence and SNPs of IL-12A. Moreover, the genotypic distributions between patients with HCC and without HCC were compared to investigate the association between the development of HCC and SNPs of IL-12A. RESULTS: We asssesed the SNPs of IL-12A at position +6400, +6624 and +7003. On the basis of logistic regression analysis, no statistically significant association with HBV persistence was observed with IL-12A exon 7 +6400, +6624, 3' UTR +7003 SNP and haplotype of IL-12A +6400/+6624/+7003. Furthermore, no statistically significant association of HCC development with IL-12A exon 7 +6400, +6624, 3' UTR +7003 SNP and haplotype of IL-12A +6400/+6624/+7003 was observed. CONCLUSIONS: These results suggest that SNPs and haplotype of IL-12A are not associated with HBV persistence and development of HCC. Further studies are needed to identify the host genetic factors in immune defense including cytokine gene polymorphisms of both IL-12A and IL-12B.

Authors report a first Korean case of polyneuropathy in an acrylamide producing factory together with an environmental and epidemiologic survey for the ten workers of the same workplace and 46 workers in the production and manufacturing acrylamide in Ulsan, Korea. The case is 30 years old man who worked in the prcduction of the acrylamide for two years. In August, 1997, he had a weakness of the lower extremity with loss of body weight of 15 Kg which progressed to paresthesia of the limbs, the loss of vibration sense, difficulty in walking, speech disturbance, dysuria, constipation, difficulty in erection and swallowing difficulty. Neurologic examination showed a complete loss of vibration and position sense, and loss of deep tendon reflex in all the limbs. There was a contact dermatitis-like skin lesion on the feet. Electrodiagnostic test showed a generalized polyneuropathy of moderate degree involving motor and sensory component of peripheral and cranial nerves. After 8 months' cessation from exposure and supportive care, his symptoms were completely resolved, but abnormality in electrodiagnostic test and vibrotactile perception threshold still persisted, although much improved than before. There were 11 workers in the same workplace of the case, producing acrylamide by microorganism as a catalyst. Environmental monitoring of the workplace revealed air-borne concentration of the acrylamide to be from 0.05 to 0.23 mg/m(3) by personal sampling and from 7.65 to 11.65 mg/m(3) by area sampling during filter exchanging process, which far exceeds TLV-TWA of 0.03 mg/m(3). However acrylamide was not detected from the plasma of the workers. Symptom questionnaire showed a markedly higher complain of neurologic symptoms, compared to the workers of the other acrylamide producing companies. Electrodiagnostic test showed a several workers are in the lower normal range without definite abnormality. Vibrotactile perception threshold by Vibratron II showed a significantly increased threshold in the workers of the same workplace compared to the other acrylamide workers and significantly decreased test score of color vision compared to normal controls. After improvement of the production process and strict wearing of the protective device, most workers reported the improvement of clinical symptoms, but vibrotactile perception threshold was not improved. These result suggests the need for the effective environmental monitoring together with a periodic biological monitoring. Development of effective screening test is urgently needed to control and assess the skin absorption of acrylamide.
