Nontuberculous mycobacterial infections are a rare, but clinically important cause of infections in continuous ambulatory peritoneal dialysis (CAPD) patients. This is typically suspected when a patient does not respond to treatment with the usual antibiotics. We describe here a case of Mycobacterium abscessus exit site infection with abdominal wall abscess formation that was associated with CAPD, which required peritoneal catheter removal, surgical debridement of the abscess and long term antibiotic therapy.

We evaluated the efficacy of non-competitive N-methyl-D-aspartate receptor antagonist MK-801 (dizocilpine) as an adjuvant therapy in experimental neonal bacterial meningitis. Meningitis was induced by injecting 10(6) colony forming units of Escherichia coli into the cisterna magna. MK-801 3 mg/kg was given as a bolus intravenous injection, 30 min before the induction of meningitis. MK-801 did not down-modulate the inflammatory parameters, such as increased intracranial pressure, cerebrospinal fluid (CSF) leukocytosis, increased lactate and TNF-alpha levels in the CSF, and hypoglycorrhachia observed in the meningitis group. MK-801 did not significantly attenuate the elevated glutamate concentration in the CSF. However, MK-801 showed some neuroprotective effects as evidenced by significant attenuation of cerebral lipid peroxidation products (conjugated dienes) and increase of brain high-energy phosphate compounds (ATP and PCr). Improvement in cerebral cortical cell membrane Na+, K+ -ATPase activity did not reach a statistical significance. These results suggest that MK-801 was effective in ameliorating brain injury in neonatal bacterial meningitis, although it failed to attenuate the inflammatory responses.

Psoas abscesses are rare clinical entities complicating Crohn's disease (CD). However, psoas abscesses can cause poor outcomes because the diagnosis is frequently delayed due to the non-specific clinical features. Recently, we managed a case of a huge iliopsoas abscess in a 21-year-old man with a 4-year history of CD who presented with a limping gait and flexion contractures of the sacroiliac joint. Notably, the iliopsoas abscess developed during induction treatment with infliximab. The patient was successfully treated with antibiotics, surgical drainage, and a right hemicolectomy. Herein we present the case with a brief review of the literature.

BACKGROUND: Diabetic patients are known to have unusually high mean intraocular pressure (IOP); attributable to autonomic dysfunction and genetic factors. A recent study reported that diabetic complications occur in not only diabetes but also prediabetes. We performed this study to analyze the relationship between glycated hemoglobin A1c (HbA1c) levels and IOP in non-diabetics using electronic medical records at the health screening center of Soon Chun Hyang University Seoul Hospital.METHODS: We considered 16,643 individuals who visited the health screening center of Soon Chun Hyang University Seoul Hospital between November 2015 and September 2017. In total, 3,029 subjects were included in the study. Exclusion criteria included a history of hypertension, diabetes, stroke, cardiovascular disease, hepatitis (A-C), cancer, other disease, fasting blood glucose of 126 mg/dL or higher, HbA1c of 6.5% or higher, and individuals whose binocular IOP could not be measured. We categorized subjects into two groups; those with HbA1c less than or equal to 5.6%, and those with HbA1c greater than 5.6% and less than 6.5%. The mean IOP of each group was compared by gender.RESULTS: After adjusting for factors affecting IOP, analysis of variance was performed to analyze the relationship between HbA1c and IOP. There was no statistically significant difference between the HbA1c groups in males. However, there was a significant difference in IOP between females in the the higher and lower HbA1c groups.CONCLUSION: There was a statistically significant relationship between mean IOP and HbA1c in females without diabetes. Further research is needed with prospective and extensive data collection.

OBJECTIVE: This study was performed to investigate the effects of pioglitazone, an insulin sensitizing agent, on insulin resistance, ovarian function and intraovarian stromal blood flow in patients with polycystic ovarian syndrome (PCOS). MATERIAL AND METHODS: Thirty patients with PCOS, aged 18~34 years, were recruited. Criteria for diagnosis of PCOS were as defined in 2003 Rotterdam consensus. They were treated for 6 months with pioglitazone at a dose of 30 mg/day orally. The hormonal blood profile, fasting serum glucose levels, a glycemic response to 75 g oral glucose tolerance test (OGTT), and an ovarian stromal artery (OSA) blood flow were assessed at baseline and after 6 months of treatment. RESULTS: Eighteen (60.0%) of 30 patients treated with pioglitazone demonstrated a spontaneous ovulation After pioglitazone treatment, fasting insulin concentrations, serum glucose levels after 75 g OGTT significantly decreased (p=0.001, p=0.04, respectively), and fasting glucose to insulin (G/I) ratio significantly increased (p<0.001). The pioglitazone treatment induced a significant reduction in serum LH, testosterone (T) and free T levels (p<0.001, p=0.02, p=0.002, respectively). The resistance index (RI) values of OSA significantly increased after treatment (p<0.001). In analyzing pioglitazone-treated patients according to their body mass index (BMI), nonobese group as well as obese group showed a significant improvement in fasting G/I ratio (p<0.01). The pioglitazone treatment induced a significant reduction in serum LH and free T levels in nonobese group (p<0.001, p<0.05, respectively) as well as obese group (p=0.001, p<0.05, respectively). The RI values of OSA significantly increased in both nonobese and obese groups after pioglitazone treatment (p<0.001, p=0.003, respectively). CONCLUSIONS: Pioglitazone could ameliorate the glycoinsulinemic metabolism, and this beneficial effects of this drug could improve the endocrine-reproductive condition associated with the decrease of ovarian stromal artery blood flow, in both nonobese and obese patients with PCOS.

PURPOSE: Considering that nutritional state correlates to immunity, we performed this study to evaluate the correlation by assessing the numerical changes of the levels of serum albumin and lymphocyte subsets. MATERIALS AND METHODS: The study was performed on patients who were diagnosed as having gastric cancer and who underwent curative surgery from August 1998 to August 2004 in the Gyeongsang National University Hospital and whose peripheral blood lymphocyte subsets were tested prior to surgery. The study population was a total of 150 cases. RESULTS: The change in the lymphocyte subsets in relation to the change in the level of serum albumin in all patients with gastric cancer was determined, and was compared to disease stages. When patients were classified by using the level of serum albumin with 3.2 mg/dl as the cut-off point (low group: serum albumin <3.2 mg/dl, normal group = serum albumin >or=3.2 mg/dl), the number of peripheral blood lymphocytes, CD3+ cells, CD4+ cells, CD8+ cells, and CD16+56 cells were, significantly lower in the group with the level of serum albumin below 3.2 mg/dl (low group) than it was in the group with a serum albumin level above 3.2 mg/dl (normal group) (P<0.05). In stage I (n=59), CD16+56 cells were significantly lower in the low group. In stage II (n=29), the number of CD16+56 cells was lower and the ratio of CD4+/CD8+ was higher in the low group than in the normal group significantly. In stage IV (n=33), except for CD19+ cells, the number of all lymphocyte subsets was significantly lower and the ratio of CD4+/CD8+ was significantly higher in the low group. CONCLUSION: The group with a low level of serum albumin had a low absolute number of lymphocyte subsets. Based on this, we reconfirmed that the nutritional state is closely related with the immune state in patients with gastric cancer.

BACKGROUND/AIMS: Gastroesophageal reflux disease (GERD) is common in asthma patients. Proton pump inhibitor (PPI) therapy improves symptoms of asthma in some patients. The objective of this study was to investigate endoscopic findings of GERD in asthma patients and to assess the effect of gastric acid suppression with the PPIs on symptom improvement and pulmonary function. METHODS: From 105 consecutive patients with GERD symptoms during follow up for asthma, 45 patients were enrolled. Patients enrolled to this study were asked about GERD symptoms before and after treating with PPI. Endoscopic findings were described according to Los Angeles classification. The improvement of asthma symptoms and follow-up pulmonary function test were investigated after administration of PPIs. RESULTS: Esophageal symptoms such as heartburn and acid reflux were present in 25 patients (55.6%), and patients without esophageal symptoms were 20 (44.4%). The degree of endoscopic abnormality was not significantly different between groups with or without esophageal symptoms. The improvement of symptoms was seen in 44 patients (97.8%) except 1 patient after administration of PPIs. The number of patients classified to the low-dose group was 7 patients (15.6%) and that of patients classified to the standard-dose group was 38 patients (84.4%). The follow-up pulmonary function test, peak expiratory flow rate (L/sec) was improved in 3 patients (3 of 7, 42.9%) of the low-dose group, and in 24 patients (24 of 38, 63.2%) of the standard-dose group. The improvement of ventilatory function was not significantly different according to dose of PPIs. CONCLUSIONS: Treatment with PPIs is expected to improve subjective symptoms and ventilatory function in asthma patients.
