Although we managed a patient with traumatic endophthalmitis with potent antibiotics for 7 days topically and systemically, her clinical symtoms and signs did not improved and her visual activity decreased from hand motion to light perception. So, we performed pars plana vitrectomy and lensectomy using the Ocutome(R) and Frognatome(TM) and achieved a successful result with final visual acuity of 50 cm finger count or better without evidence of phthisis bulbi in this case.

Spinal cord injury often leads to central neuropathic pain syndromes, such as allodynic and hyperalgesic behaviors. Electrophysiologically, spinal dorsal horn neurons show enhanced activity to non-noxious and noxious stimuli as well as increased spontaneous activity following spinal cord injury, which often called hyperexcitability or central sensitization. Under hyperexcitable states, spinal neurons lose their ability of discrimination and encoding somatosensory information followed by abnormal somatosensory recognition to non-noxious and noxious stimuli. In the present review, we summarize a variety of pathophysiological mechanisms of neuronal hyperexcitability for treating or preventing central neuropathic pain syndrome following spinal cord injury.

Congenital hypertrophic pyloric stenosis is the most common intra-abdominal disease required surgery during the first few months of life. The expression of pyloric stenosis is dependent upon the genetic influence of ancestors affected with the disease, as well as unknown environmental influences in the postnatal period. Pyloric stenosis has been reported in multiple sibs in a family, which suggests the genetic influence on the expression of this disease. Until now, the genetic influence is thought a sex-modified polygenic or multifactorial background which facilitates the expression of a common dominant gene. We experienced a case of congenital hypertrophic pyloric stenosis in a two siblings. The siblings suffered projectile vomiting for 2~4 days at 16 days old of age and 15 days old of age. After we confirmed the diagnosis by upper gastrointestinal series and abdominal sonogram, the Fredet-Ramstedt pyloromyotomy was done successfully. This case suggests the genetic influence on the expression of this disease.

Staphylococci are known to produce catalase, but there have been a few case reports of catalase-negative Staphylococcus aureus. The present report describes the first case of catalase-negative S. aureus associated with vaselinoma to our knowledge. We isolated a catalase-negative strain of S. aureus from a penile wound of a 35-year-old man who injected with vaseline into his penis 9 months ago. Colony morphology and biochemical reactions of the strain were typical of S. aureus except for catalase. The patient was diagnosed as having vaselinoma with wound infection and was successfully treated by the surgical removal of the vaseline granuloma and the administration of appropriate antibiotics. Catalase-negative S. aureus is considered to be a very rare variant of S. aureus. To date the number of reported cases of catalase-negative S. aureus is very few, so further studies need to be conducted to evaluate its clinical relation.

OBJECTIVES: Delphinidin is one of the anthocyanidins. It is believed to have anti-inflammatory property including antioxidant, antiangiogenic, and anti-cancer properties. However, the anti-inflammatory effect of delphinidin in mucin-producing human airway epithelial cells has not been determined. Therefore, this study was conducted in order to investigate the effect and the brief signaling pathway of delphinidin in lipopolysaccharide (LPS)-induced MUC8 and MUC5B expression in human airway epithelial cells. METHODS: In mucin-producing human NCI-H292 airway epithelial cells and primary cultures of normal nasal epithelial cells, the reverse transcriptase-polymerase chain reaction (RT-PCR), real-time PCR, enzyme immunoassay were used for investigating the expressions of MUC8, MUC5, and Toll-like receptor 4 (TLR4), after LPS treatment and delphinidin treatment. And the signaling pathway of delphinidin on LPS-induced MUC8 and MUC5B expression was investigated using the RT-PCR, and immunoblot analysis. To confirm the involvement of TLR4 in LPS-induced MUC8 and MU5B expression, the cells were transfected with TLR4 siRNA. RESULTS: In NCI-H292 airway epithelial cells, LPS (100 ng/mL) significantly induced TLR4, MUC8, and MUC5B expression. TLR4 siRNA significantly blocked LPS-induced MUC8 and MUC5B mRNA expression. LPS (100 ng/mL) significantly activated the phosphorylation of extracellular signal related kinase (ERK) 1/2 and p38 mitogen-activated protein kinase (MAPK). Delphinidin (50 and 100 microM) inhibited LPS-induced TLR4, MUC8, and MUC5B expression and LPS-induced phosphorylation of ERK1/2 and p38 MAPK. In the primary cultures of normal nasal epithelial cells, delphinidin (50 and 100 microM) significantly inhibited LPS-induced TLR4, MUC8, and MUC5B gene expression. CONCLUSION: These results suggest that delphinidin attenuates LPS-induced MUC8 and MUC5B expression through the TLR4-mediated ERK1/2 and p38 MAPK signaling pathway in human airway epithelial cells. These findings indicated that delphinidin may be a therapeutic agent for control of inflammatory airway diseases.

BACKGROUND: The glomerulonephritis appears in various clinical presentations. Renal biopsy is important diagnostic tool for treatment decision and prognosis prediction of glomerulonephritis. We tried to study on the clinical presentations of glomerulonephritis through histopathological findings and treatment responses in elderly patients. METHODS: We made an retrospective analysis in elderly patients aged over 60 years performed renal biopsy in our medical center from January 1991 to February 2005. RESULTS: Of all the 42 patients, the mean age of the patients was 64.6+/-3.5 years, 24 male and 18 female patients were included(1.3:1). Patients aged 60-64 years (n=26, 62%) were majority. On clinical indications of renal biopsies, 17 patients had nephrotic syndrome, 10 had asymptomatic urinary abnormality, 5 had gross hematuria, and 5 had acute azotemia. The results of renal biopsies presented that 30 patients (71%) had primary glomerulonephritis, 9 patients (22%) had secondary glomerulonephritis. Among primary glomerulonephritis, membranous nephropathy (n=10) was most common, followed by IgA nephropathy (n=7),focal segmental glomerulos-clerosis (n=3), membranoproliferative glomerulonephritis (n=2), and mesangioproliferative glomerulonephritis (n=2). In secondary glomer-ulonephritis, there were diabetic nephropathy (n=2), lupus nephritis (n=2), cancer-related nephritis (n=2), poststreptococcal glomer-ulonephritis (n=1), Henoch-Schonlein nephritis (n=1), amyloidosis (n=1). In the cases of nephrotic syndrome, primary nephrotic syndrome (n=12, 71%) is more prevalent than secondary nephrotic syndrome (n=3, 18%). The most common cause of primary nephrotic syndrome was membranous nephropathy (n=8). The causes of asymptomatic urinary abnormality were IgA nephropathy (n=4), lupus nephritis (n=2), membranous nephropathy (n=1), mesangioproliferative glomerulonephritis (n=1). By the complications of renal biopsy, only a few patients presented new-onset hematuria, hematoma, aggravation of hypertension, but, severe complication including an infection or a death was none. 8 of 12 patients with primary nephrotic syndrome were treated, 5 patients of those were shown complete response (n=3) or partial response (n=2). CONCLUSION: Various clinical presentations of glomerulonephritis were shown to elderly patients. Number of complications after renal biopsies were relatively small, and good responsiveness to treatment could be expected in the elderly patients. Therefore it is reasonable to perform a renal biopsy if indicated.

A 59-year-old woman was scheduled to undergo a robot-assisted distal gastrectomy under general anesthesia. During the operation, the vital signs were maintained in normal range. After 7 hours of surgery, the pulse oxymeter graph became flat and the end tidal CO2 concentration suddenly decreased. Palpation of the carotid artery revealed no heart beat but the EKG continued to show sinus rhythm. Pulseless electrical activity (PEA) was diagnosed. An advanced cardiopulmonary life support protocol for PEA was immediately initiated, which included chest compressions and doses of IV cardiovascular drugs. However, in spite of continuous CPR, the heart wasn't recovered from the arrest. We experienced cardiac arrest for pulseless electrical activity during robot-assisted distal gastrectomy.
