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.

We experienced a case of congenital choledochal cyst in a 6 months old korean female infant with complaints of abdominal distension, jaundice, loose stool and a large mass of the abdomenin the right upper quadrant since about 3 months prior to admission. The diagnosis was confirmed by clinical symptoms and signs, physical examination, radiological findings and surgical findings. She was operated with good result and discharged in well condition 28 days after. The review of the related literature was made briefly.

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.

The tyrosine-protein kinase Tec (TEC) is a member of non-receptor tyrosine kinases and has critical roles in cell signaling transmission, calcium mobilization, gene expression, and transformation. TEC is also involved in various immune responses, such as mast cell activation. Therefore, we hypothesized that TEC polymorphisms might be involved in aspirin-exacerbated respiratory disease (AERD) pathogenesis. We genotyped 38 TEC single nucleotide polymorphisms in a total of 592 subjects, which comprised 163 AERD cases and 429 aspirin-tolerant asthma controls. Logistic regression analysis was performed to examine the associations between TEC polymorphisms and the risk of AERD in a Korean population. The results revealed that TEC polymorphisms and major haplotypes were not associated with the risk of AERD. In another regression analysis for the fall rate of forced expiratory volume in 1 second (FEV1) by aspirin provocation, two variations (rs7664091 and rs12500534) and one haplotype (TEC_BL2_ht4) showed nominal associations with FEV1 decline (p = 0.03-0.04). However, the association signals were not retained after performing corrections for multiple testing. Despite TEC playing an important role in immune responses, the results from the present study suggest that TEC polymorphisms do not affect AERD susceptibility. Findings from the present study might contribute to the genetic etiology of AERD pathogenesis.

PURPOSE: The human WD repeat-containing protein 46 (WDR46; also known as C6orf11), located at the disease-relevant centromere side of the class II major histocompatibility complex region, is hypothesized to be associated with risk of aspirin-exacerbated respiratory disease (AERD) as well as a decline in forced expiratory volume in the first second (FEV1), an important diagnostic marker of asthma. METHODS: To investigate the association between WDR46 and AERD, five single-nucleotide polymorphisms (SNPs) were genotyped in 93 AERD cases and 96 aspirin-tolerant asthma controls of Korean ethnicity. Three major haplotypes were inferred from pairwise comparison of the SNPs, and one was included in the association analysis. Differences in the frequency distribution of WDR46 SNPs and haplotype were analyzed using logistic and regression models via various modes of genetic inheritance. RESULTS: Depending on the genetic model, the logistic and regression analyses revealed significant associations between rs463260, rs446735, rs455567, rs469064, and WDR46_ht2 and the risk of AERD (P=0.007-0.04, Pcorr=0.01-0.04) and FEV1 decline after aspirin provocation (P=0.006-0.03, Pcorr=0.01-0.03). Furthermore, functional analysis in silico showed that the G>A allele of rs463260 located in the 5' untranslated region potentially matched a nucleotide sequence within an upstream open reading frame of WDR46. CONCLUSIONS: These findings show for the first time that WDR46 is an important genetic marker of aspirin-induced airway inflammation and may be useful for formulating new disease-management strategies.
