Although aseptic meningitis is a common neurological disorder, a combination of acute urinary retention and aseptic meningitis has been recognized rarely. To our knowledge, only a few case reports are available on this combination and the underlying pathology remains unclear. We reported on a patient showing acute urinary retention and aseptic meningitis with a review of the literatures.

Purpose: Association between hyponatremia and the severity of respiratory symptoms in infants with respiratory syncytial virus (RSV) infection has not yet been studied. This study aimed to compare respiratory symptoms, assessed using the Pediatric Respiratory Score (PRS), in infants with RSV infection, with or without hyponatremia. Methods: RSV­positive patients aged <12 months who were admitted with respiratory symptoms within 7 days of onset at Jeonbuk National University Children’s Hospital from January 2016 to December 2019 were retrospectively analyzed. Each patient was categorized into those with or without hyponatremia (serum sodium concentration of <136 mmol/L). Clinical findings included PRS on the day of admission. Results: The mean±standard deviation age of the 125 patients included in the study was 2.7±3.3 months, and, 20 patients (16.0%) showed hyponatremia. Infants with RSV infection and hyponatremia had lower birth weights, longer hospital stays, and higher blood urea nitrogen level. The C­reactive protein level was significantly higher in the hyponatremic infants, who had higher PRSs. The non­hyponatremia group had more normal PRSs than the hyponatremia group, which had more severe PRSs. After adjustment for age at admission, blood urea nitrogen level (OR, 1.218; 95% CI, 1.023 to 1.451; P<0.05), and PRS grade (OR, 2.885; 95% CI, 1.158 to 7.187; P< 0.05) were identified as independent risk factors. Conclusion Hyponatremia was strongly associated with respiratory severity in infants with RSV. Therefore, infants admitted with RSV infection who show higher PRS grade need to be evaluated and treated for hyponatremia.

PURPOSE: Adverse reactions to mosquito bites have been recognized for some time, and these usually consist of large swellings, generalized urticaria, angioedema, and less frequently asthma. There have been some efforts to define immunologic characteristics of mosquito allergens throughout the world. But, in Korea, the immunologic analysis of mosquito allergen have not been made. METHODS: Extracts of locally distributed female mosquito Culex pipiens, were prepared from their heads and thoraxes. By sodium dodecylsulfate-polyacrylamide gel electrophoresis, proteins of two extracts were isolated. Then their proein bands were transferred to nitrocellulose membrane. Immunoblotting was performed with sera of allergic patients to mosquito bites, then completed by antibodies to human IgE. RESULTS: Immunoblotting showed IgE binding proteins weighing 70 kD, 60 kD, 34 kD in Culex pipiens. CONCLUSION: We found that mosquito antigens induced IgE response, and it suggested that species-specific antigens exist. Further investigation using salivary gland extracts from Culex genus are needed in identifying specific allergens.

BACKGROUND/AIMS: Endoscopic mucosal resection (EMR) currently serves as the minimally invasive treatment of choice for early gastric cancer and premalignant lesions of the stomach. There have been few studies addressing whether a proton pump inhibitor or a histamine 2-receptor antagonist is the most effective treatment for iatrogenic ulcers after EMR. We compared the effectiveness of pantoprazole and famotidine in treating iatrogenic ulcers and preventing bleeding after EMR without endoscopic submucosal dissection. METHODS: Between March 2006 and April 2007, we retrospectively analyzed the effect of famotidine (40 mg/day) and pantoprazole (40 mg/day) on the healing of iatrogenic ulcers and control of bleeding after EMR. RESULTS: During the study period, 126 patients underwent EMR. Eighty-one received famotidine, and 45 received pantoprazole. The mean duration of drug therapy was 44 days in each group. The stages of ulcers at 1 to 3 months after EMR were mostly scar stage, and there was no specific difference between the groups. Delayed bleeding was seen after EMR in one patient (1.2%) from the famotidine group and in one patient (2.2%) from the pantoprazole group. There were no other major complications after EMR. CONCLUSIONS: Famotidine was no different than pantoprazole in its effectiveness toward preventing delayed bleeding and promoting healing of iatrogenic ulcers after EMR.

The aim of this study was to develop guidelines for the prevention and management of particulate matter (PM)/Asian dust particle (ADP)-induced adverse effects in patients with pulmonary diseases. The guideline development committee reviewed the literature on particulate matter, ADP, and pulmonary diseases. In adults, exposure to particulate matter with a diameter of 10 microm or less (PM10) induces a decline in lung function. PM exposure confers an increased risk of lung cancer, and PM10 is associated with increased hospital admission and mortality due to chronic obstructive pulmonary disease. ADP exposure is associated with increased hospital admission and emergency room visits due to chronic obstractive pulmonary disease exacerbation. Idiopathic pulmonary fibrosis exacerbation may also be induced by pollution, although the evidence for this is very weak. There is no published study on the proper prevention or management of the exacerbation of pulmonary diseases due to PM or ADP exposure. The preventive use of a facial mask with a filter in patients with pulmonary disease should be considered carefully because there have been no clinical study of the efficacy and adverse effects of masks in pulmonary diseases. The committee created guidelines based on a discussion of the peer-reviewed literature. The proper management of PM- and ADP-induced exacerbation of pulmonary disease and the efficacy of facial mask use should be evaluated in future studies.

We present a case of intrapancreatic accessory splenic infarction in a 28-year-old woman. It was discovered during a workup for an acute right epigastric pain. Computed tomography imaging of abdomen demonstrated a hemorrhagic high attenuation with enhancing solid portion in the tail of pancreas. The clinical and radiological differential diagnosis included pancreatic mucinous cystic neoplasm, pancreatic endocrine neoplasm, solid pseudopapillary tumor, ductal adenocarcinoma, and metastasis. A distal pancreatectomy was completed. The microscopic examination revealed heterotopic splenic tissue with infarction and her abdominal pain disappeared. In this case report, we first describe a symptomatic accessory splenic infarction which presented as a hemorrhagic mass in the tail of pancreas mimicking pancreatic neoplasm.

Balo's concentric sclerosis is regarded as a rare variant of multiple sclerosis. Traditionally, Balo's concentric sclerosis was a post-mortem diagnosis, but the recent introduction of brain magnetic resonance imaging (MRI) scans may allow noninvasive access without biopsy. Brain MRI findings of Balo's concentric sclerosis is characteristic concentric configuration of alternating bands of white matter of different pathology, with relatively preserved myelination alternating with regions of demyelination in the cerebral white matter. We report a case of Balo's concentric sclerosis with recurrent optic neuritis.

BACKGROUND AND PURPOSE: The use of decompressive hemicraniectomy (DHC) for the treatment of malignant cerebral edema can decrease mortality rates. However, this benefit is not sufficient to justify its use in elderly patients. We investigated the effects of therapeutic hypothermia (TH) on safety, feasibility, and functional outcomes in elderly patients with malignant middle cerebral artery (MCA) infarcts. METHODS: Elderly patients 60 years of age and older with infarcts affecting more than two-thirds of the MCA territory were included. Patients who could not receive DHC were treated with TH. Hypothermia was started within 72 hours of symptom onset and was maintained for a minimum of 72 hours with a target temperature of 33°C. Modified Rankin Scale (mRS) scores at 3 months following treatment and complications of TH were used as functional outcomes. RESULTS: Eleven patients with a median age of 76 years and a median National Institutes of Health Stroke Scale score of 18 were treated with TH. The median time from symptom onset to initiation of TH was 30.3±23.0 hours and TH was maintained for a median of 76.7±57.1 hours. Shivering (100%) and electrolyte imbalance (82%) were frequent complications. Two patients died (18%). The mean mRS score 3 months following treatment was 4.9±0.8. CONCLUSIONS: Our results suggest that extended use of hypothermia is safe and feasible for elderly patients with large hemispheric infarctions. Hypothermia may be considered as a therapeutic alternative to DHC in elderly individuals. Further studies are required to validate our findings.
