BACKGROUND: The clinical characteristics and significance of peritoneal fluid eosinophilia (PFE) in patients on continuous ambulatory peritoneal dialysis (CAPD) in Korea were uncertain. The present study was performed to clarify the clinical characteristics of PFE in our CAPD patients. METHODS: Between January 2000 and December 2001, we analyzed retrospectively the clinical data of 112 patients on CAPD at two renal centers. RESULTS: The mean period of the observation was 12.6+/-6.7 months, and the total number of peritoneal effluent sampling was 1, 024 (10.5/patient-year). PFE was found in 4.4% of patients. The incidence of PFE was 4.25 per 100 patients/year. Sixty percent of patients with PFE experienced within 2 weeks of initiation of dialysis. The duration of PFE episode varied from 1 to 4 days with the mean value of 2.8 days. All PFE episodes except one patient with abdominal pain treated by oral prednisolone had no symptoms and was spontaneously resolved. The only distinction between the patients with PFE and those without was concomitant peripheral blood eosinophilia (80.0% vs. 15.8%, p=0.0027). Other factors such as age, sex, primary renal disease, bacterial peritonitis, previous use of heparin or antibiotics, blood in peritoneal fluid, and allergic history were not significantly different between the two groups. CONCLUSION: The majority of PFE episode in CAPD patients developed within 2 weeks of initiation of dialysis and spontaneously resolved without treatment. Peripheral blood eosinophilia was a good predictor of PFE.

Cellular schwannoma is a variant of schwannoma, and is diagnosed as malignant tumor in over one fourth of cases because of its cellularity, mitotic activity and the occasional presence of bone destruction. This tumor is a tumor with low malignant potential and usually occurs in peripheral nervous system, mainly in the posterior mediastinum and retroperitoneal space. But pelvic retroperitoneal cellular schwannoma is very rare. Recently, we experienced a case of pelvic retroperitoneal cellular schwannoma in a 42-year-old woman; in reporting the case a brief review of the literature is included.

Objectives: White matter hyperintensities are known to influence dementia in Alzheimer’s disease.
Genetic components are suggested as putative risk factors for vascular pathology and cognitive
decline. This study aimed to determine whether there is an association between candidate genetic
polymorphisms and the severity of white matter hyperintensities in patients with Alzheimer’s disease.
Methods: Seventy-five patients diagnosed with Alzheimer’s disease underwent genetic tests for specific
alleles of apolipoprotein E, angiotensin-converting enzyme, and methylenetetrahydrofolate reductase.
All patients underwent brain magnetic resonance imaging scans and neuropsychological tests. The
severity of white matter hyperintensities was semiquantified using the CREDOS rating scale, and
patients were divided into three groups according to their rating. Results:The severity of white matter
hyperintensities was related to age and hypertension. However, none of the gene polymorphisms we
tested was found to be associated with the severity of white matter hyperintensities.
Conclusion:The genetic polymorphisms found in apolipoprotein E, angiotensin-converting enzyme
and methylenetetrahydrofolate reductase did not contribute to white matter hyperintensities in
Alzheimer’s disease.Only age and hypertension factors were found to be contributory to white matter
hyperintensities.

Background:
The long-term care (LTC) group has higher rates of chronic disease and disability registration compared to the general older people population. There is a need to provide integrated medical services and care for LTC group. Consequently, this study aimed to identify medical usage patterns based on the ratings of LTC and the characteristics of benefits usage in the LTC group.
Methods:
This study employed the National Health Insurance Service Database to analyze the effects of demographic and LTC-related characteristics on medical usage from 2015 to 2019 using a repeated measures analysis. A longitudinal logit model was applied to binary data, while a linear mixed model was utilized for continuous data.
Results:
In the case of LTC ratings, a positive correlation was observed with overall medical usage. In terms of LTC benefit usage characteristics, a higher overall level of medical usage was found in the group using home care benefits. Detailed analysis by medical institution classification revealed a maintained correlation between care ratings and the volume of medical usage. However, medical usage by classification varied based on the characteristics of LTC benefit usage.
Conclusion
This study identified a complex interaction between LTC characteristics and medical usage. Predicting the requisite medical services based on the LTC rating presented a challenge. Consequently, it becomes essential for the LTC group to continuously monitor medical and care needs, even after admission into the LTC system. To facilitate this, it is crucial to devise an LTC rating system that accurately reflects medical needs and to broaden the implementation of integrated medical-care policies.

PURPOSE: Heart rate variability (HRV) is a tool used to measure autonomic nervous function; however, there is no evidence that it can be used to define sympathetic hyperactivity in men with lower urinary tract symptoms (LUTS). We suspected that LUTS would differ between sympathetic hyperactive and hypoactive patients. Therefore, we measured HRV and divided the LUTS patients into two groups, a sympathetic hyperactive group and a sympathetic hypoactive group according to the low frequency/high frequency (LF/HF) ratio and made clinical comparisons between the groups. METHODS: A total of 43 patients with symptomatic LUTS (International Prostate Symptom Score [IPSS] over 8) and 49 healthy volunteers were enrolled. No subjects had diseases that could affect the autonomic nervous system, such as diabetes or hypertension. Electrocardiographic signals were obtained from subjects in the resting state and HRV indexes were calculated with spectral analyses. We divided the LUTS patients into two groups by an LF/HF ratio of 1.9, which was the median value in the healthy volunteers, and compared the differences in clinical characteristics, IPSS, prostate-specific antigen (PSA), and transrectal ultrasound (TRUS) results. The parameters were compared by independent sample t-test by use of SPSS ver. 19. RESULTS: There were no significant differences in age, serum PSA, or volume of the prostate between the 2 LUTS groups. However, analyzing IPSS questionnaires between two groups showed that there were significant differences in mean of Q2 score (frequency) and storage symptom score ([Q2+Q4+Q7]/3) (P<0.05). CONCLUSIONS: We suggest that an imbalance of autonomic nervous system activity may be a factor that evokes varieties of symptoms in men with LUTS. LUTS patients with hypoactive sympathetic tone may suffer from frequency and storage symptoms.

Acute otitis media (AOM) is one of the most common childhood infectious diseases. Despite antibiotic treatment for AOM, AOM and its complication still continue to develop. Acute mastoiditis is a serious complication of AOM and epidural abscess constitutes the commonest of all intracranial complication of AOM. Neurological complication of acute mastoiditis are rare but can be life threatening. Their presentation may be masked by the use of antibiotics. We report the rare case of acute otitis media progressing to acute mastoiditis, epidural abscess formation and lateral sinus thrombophlebitis caused by Streptococcus pneumoniae in a child. She was admitted with acute otitis media with fever. Despite proper antibiotics, acute mastodititis and epidural abscess were developed, and after surgical drainage and antibiotics therapy she was recovered without sequalae.

Melanoacanthoma is a rare benign mixed tumor of both keratinocytes and melanocytes. Although some authors said that it is a rare variant of seborrheic keratosis, it has clinical and histological features distinct from seborrheic keratosis. It has large dendritic melanin-laden melanocytes throughout all levels of epidermis showing a disruption of melanin transfer from the melanocytes to neighboring keratinocytes. However, it is difficult to distinguish melanocytes clearly from cutaneous pigment in immunohistochemical stain with usually used brown chromogen. We used chromogen with brick-red indicator product (VECTOR(R) NovaRED(TM)) in S-100 and melan-A immunohistochemical staining to distinguish melanocytes from melanin laden keratinocytes. We suggest that the immunohistochemical staining using this novel chromogen may be useful in the diagnosis of melanoacanthoma.

BACKGROUND: Psoriasis is one of the relatively common chronic relapsing cutaneous disorders. The etiology and pathogenesis of the psoriatic skin lesion are still unknown. A colonization of microbacterial organisms especially Staphylococcus aureus (S. aureus) have been considered as a factor for development and exacerbation of psoriatic skin lesion. OBJECTIVES: The purpose of this study was to observe the bacteria on the skin of the patients with psoriasis and healthy normal persons, and evaluate the relations between bacterial density, S. aureus colonization, and severity of psoriatic skin lesions. MATERIALS & METHODS: Twenty two psoriasis patients and 25 healthy normal persons were involved for this study. Psoriasis patients were classified according to a severity estimated by PASI (Psoriasis Area and Severity Index) and activity of psoriatic skin lesions. Microbial sampling by tape method (3M, 5x5 cm) were performed on the psoriatic skin lesion and uninvolved skin in the patients of psoriasis, and on the inner forearm of the normal healthy person. Microbial sampling by a swab were also carried out from nasal mucosa. The tapes were gently contacted on the blood agar plate, and cultured in aerobic condition(30 degrees C) during 2-5 days and the numbers of colony forming unit (CFU) were estimated. RESULTS: The results were as follows; Total numbers of CFU in the lesion and uninvolved skin of psoriasis patients were significantly higher than those of the healthy controls (p<0.05). Total numbers of CFU relatively were correlated with PASI score (p<0.05), but they were not correlated with duration of the disease (p>0.05). The activity of psoriasis was relatively correlated with PASI score and total number of CFU (p<0.05). The number of S. aureus in the psoriatic plaque was not significantly higher than number of uninvolved skin in psoriasis, and number of healthy normal persons (p>0.05). There was a significant correlation between the numbers of S. aureus on the lesional and uninvolved skin and that on the nasal mucosa. (p<0.05). CONCLUSION: This study demonstrates that bacterial density is significantly higher on the psoriatic skin lesions, which suggests that bacterial colonization on the skin has a role in the development and exacerbation of the psoriatic lesion.

Ulcerative colitis is a chronic relapsing inflammatory disease of the colonic and rectal mucosa, which affects children as well as adults. Inflammation caused by ulcerative colitis is limited to the colon and rectum, to the mucosa and submucosa, and is involved continuously, with varying degrees of ulceration, hemorrhage, edema, and regenerating epithelium. Ulcerative colitis most commonly presents with the onset of diarrhea, later associated with hematochezia, but usually without systemic signs of fever, weight loss, or hypoalbuminemia. Approximately 30% of cases have moderate signs of systemic illness. Although less commonly seen than in Crohn's disease, the first sign of ulcerative colitis may be growth failure characterized by decreased linear growth velocity. We experienced a case of ulcerative colitis with growth disturbance and treated with sulfasalazine. During follow up for a year, the symptoms subsided, and the height and weight increased.
