BACKGROUND: Pityriasis versicolor is often found following pathologic transformation of Malassezia fungi from yeast to mycelial forms by a poorly understood mechanism and is characterized by squamous skin lesions manifesting hyper- or hypo-pigmentation. Itraconazole is a synthetic oral antifungal agent of triazole family, which acts as a selective inhibitor of the cytochrome P-450-dependent synthesis of ergosterol and is reported to demonstrate a potent antifungal efficacy against Malassezia yeasts. OBJECT: The present clinical study was designed to evaluate the therapeutic efficacy of one- week regimen of itraconazole by studying 20 patients with pityriasis versicolor, who were diagnosed both clinically and mycologically. In addition, we wished to identify Malassezia species from skin lesions of pityriasis versicolor and examine the possible correlation of a certain Malassezia(M.) species and pityriasis versicolor. METHODS: Twenty patients (ages, 18 to 49) were included in the study, following the diagnosis of pityriasis versicolor, which was based on clinical examinations and mycological studies (microscopy and culture). Patients received a single 200 mg dose of itraconazole (Sporanox? capsules daily with a full meal for one week. For all patients, clinical examinations and culture and microscopic studies were done before treatment, at the end of treatment, and 4 weeks later. Scales obtained from skin lesions were studied by Parker-KOH smear examination and culture studies to identify Malassezia yeasts. Cultures were done using agar media of Leeming & Notman. RESULTS: By comparing skin lesions before and immediately after treatment, marked improvement was observed in 7 patients (35%) and moderate improvement in 12 patients (60%) among a total of 20 patients, and 1 patient (5%) showed no response. On the other hand, by comparing skin lesions examined before treatment and 4 weeks after completing medication, complete cure was observed in 13 cases (65%), marked improvement in 5 (25%), and moderate improvement in 2 (10%). With culture studies before treatment, M. globosa, M. furfur, and M. restricta were isolated as a major fungal species in 18, 1, and 1 patients, respectively. CONCLUSION: The result suggested that administration of a single dose of 200 mg itraconazole (Sporanox? capsules daily for a week is a very effective treatment for pityriasis versicolor and also indicated that pityriasis versicolor is very closely related with the infection of M. globosa.

We report a case of infantile acropustulosis in a 7 month-old female infant who had a family history of scabies in her parents and brother. She had pruritic papulovesicles and pustules, predominantly on the hands and feet. Histopathologically, there was a well-circumscribed unilocular, subcorneal pustule filled with neutrophils, mostly. Under the diagnosis of an infantile acropustulosis associated with scabies, she was treated with a potent topical corticosteroid and oral antihistamines without recurrence.

Although listeria monocytogenes is widely distributed in nature, it rarely causes clinical infection in previously healthy people. However, this microorganism may cause severe infectious disease in pregnant women and newborns due to impaired cell-mediated immunity. Various clinical symptoms have been described such as sepsis, central nervous system infections, endocarditis, gastroenteritis and localized infections. A clinical presentation of listeriosis in an early third trimester pregnant woman and in a preterm infant is emphasized in addition to taking a careful patient history, early empirical administration of antibiotics, aggressive ventilation therapy and also pharmacological support.

OBJECTIVES: Schizophrenic patients have been reported to be associated with abnormal performance on a broad range of neuropsychological tests. But it has been a persistent controversy in the neuropsychology of schizophrenia whether this disorder is characterized by generalized deficits or specific deficits. The purpose of this study was to investigate, using standardized Benton Neuropsychological Assessment(BNA), whether the specific pattern of neurocognitive deficits is found in schizophrenics. METHODS: The subjects were composed of (1) 30 schizophrenic inpatients who were diagnosed as paranoid subtype according to DSM-IV diagnostic criterior and (2) 30 normal subjects with matching demographic variables(i.e. age, sex, educational level). All tests of BNA were given to schizophrenic patients and normal subjects, and the performances of schizophrenic patients and normal subjects were compared on all aspects of BNA. Schizophrenic symptoms were assessed via Positive and Negative Syndrome Scale(PANSS) to determine the relationship between clinical symptoms and schizophrenic cognitive deficits. RESULTS: Of 12 tests of BNA, schizophrenic patients' performances on Serial Digit Learning(SDL), Facial Recognition Test(FR), Tactile Form Perception(TFP), Finger Localization(FL) were significantly lower than those of normal subjects. In addition, schizophrenic patients showed significantly lower performances than those of normal subjects on Right Hand, Left Hand, Identification of two simultaneously touched fingers of FL, and more Peripheral Error on Visual Form Perception Test(VFPT). Finally, no significant correlation was found with respect to the relationships between total scores, positive symptom scores, negative symptom scores of PANSS, and all scores of BNA tests in schizophrenic patients. CONCLUSION: These results suggest that schizophrenic patients may have a specific pattern of neurocognitive deficits in verbal working memory, learning, attention, and complex sensory information processing in visual and haptic modality such as facial perception skills, tactile information processing, independent of psychotic symptoms. The pattern of deifcits is at least in partial, in agreement with many previous study results. On the tests of linguistic functions, visuospatial perception, and constructional abilities, schizophrenic patients' performances were not significantly different from those of normal subjects. The findings on visuospatial perception and constructional abilities imply that some posterior cortical zones may be relatively uncompromised in schizophrenia. Both poor performances on object recognition tests relative to normal performances on object location tests and verbal working memory dysfunction may be associated with the putative dysfunction of the reciprocal connections either (1) between the prefrontal and parietal cortex or (2) between the prefrontal cortex and hippocampal formation. This tentative explanation remains to be confirmed.

Purpose: We compared the accuracies of formulae used to calculate intraocular lens (IOL) powers when predicting postoperative refraction, by the type of lens. Methods: We retrospectively reviewed the medical records of 445 eyes (332 patients) that had undergone phacoemulsification and posterior chamber lens implantation between January 2017 and December 2019. Axial length was measured via optical low-coherence reflectometry (Lenstar LS900; Haag-Streit, Bern, Switzerland). The IOLs implanted were all one-piece acrylic IOLs, thus, the ALCON SN60WF (215 eyes), the TECNIS ZCB00 (139 eyes), and the MBI SAL302AC (91 eyes). The mean absolute errors (MAEs) and mean numerical errors (MNEs) were calculated using the SRK-2, SRK/T, Hoffer Q, Holladay, Olsen, and Barrett formulae 1-2 weeks after surgery. Results: For the ALCON SN60WF, the Hagis formula yielded the lowest power and thus tended to be myopic, but we found no significant difference in the MAE. For the TECNIS ZCB00, the Olsen formula yielded the lowest power and thus tended to be myopic, and the Barrett formula yielded the lowest MAE. For the MBI SAL302AC, all MAEs and MNEs were similar. Conclusions Depending on the IOL type, the IOL power calculation formulae differed in terms of predicting postoperative refraction.

PURPOSE: To evaluate efficacy and complication of stereotactic radiosurgery using stereotactic body frame. METHODS AND MATERIALS: From December 1997 to June 1999, 11 patients with primary and metastatic tumors were treated with stereotactic radiosurgery using stereotactic body frame(Precision Therapy(TM)). Three patients were treated with primary hepatoma and seven with metastatic tumor from liver, lung, breast, trachea and one with arteriovenous malformation on neck. We used vacuum pillow for immobilization and made skin marker on sternum and tibia area with chest marker and leg marker. Diaphragm control was used for reducing movement by respiration. CT-simulation and treatment planning were performed. Set-up error was checked by CT-Simulator before each treatment. Dose were calculated on the 80~90% isodose of isocenter dose and given consecutive 3 fractions for total dose of 30 Gy (10 Gy/fraction). RESULTS: Median follow-up was 12 months. One patient (9%) showed complete response and four patients (36%) showed partial response and others showed stable disease. Planning target volumes (PTV) ranged from 3 to 111 cc (mean 18.4 cc). Set-up error was within 5 mm in all directions (X, Y, Z axis). There was no complication in all patients. CONCLUSION: In primary and metastatic tumors, stereotactic radiosurgery using stereotactic body frame is very safe, accurate and effective treatment modality.

BACKGROUND: To develop a Korean version of the QOLIE-31 and to confirm its psychometric properties. METHODS: The QOLIE-31 was adapted to Korean language through a translation-back translation procedure. Data were collected from 397 adult epilepsy patients. Patients were administered the Quality of Life in Epilepsy Inventory-31 (QOLIE-31), Korean Wechsler Intelligence Scale (KWIS), the Functional Assessment of Cancer Therapy-General (FACT-G), state scale of the State-Trait Anxiety Inventory (STAI), and the Center for Epidemiological Studies-Depression Scale (CES-D). We assessed internal consistency and test-retest reliabilities and construct validity. RESULTS: Cronbach's alpha ranged from 0.69 to 0.86, and test-retest reliability was between 0.50 and 0.71, demonstrating that the items of OOLIE-31 are internally consistent and temporally stable. Pearson's correlations among the QOLIE-31 and emotional well-being, state anxiety, and depressive symptoms were high. Most QOLIE-31 sub-scales discriminated well between patients according to seizure frequency, number of antiepileptic drugs, employment, economic status and depressive symptoms. CONCLUSION: The Korean version of the QOLIE-31 was reliable, and showed construct validity comparable with the original U.S version. Results confirmed that the QOLIE-31 can be applied as one of the specific measures of quality of life in Korean epilepsy patients.

Dyskeratosis congenita (DC) is a rare genetic disorder encompassing abnormal skin pigmentation, dystrophic nails, leukoplakia of mucous membranes and others. Bone marrow failure is the cause of early mortality. Moreover, DC is known for its predisposition to malignancy. X-linked recessive, autosomal dominant and autosomal recessive forms of the disease are recognized. We describe here a rare case of DC in a 4-year-old girl showing dark skin, dystrophic toe nails, and mild bone marrow failure. Autosomal recessive disease was suggested as the patient is female, and tests for DKC1 and hTR mutations were negative. Intermittent treatment with oxymetholone and prednisolone for about 26 months resulted in stable hemoglobin and platelet response.

The phylogenetic relationships of the 3 Neodiplostomum spp. (Digenea: Neodiplostomidae) occurring in Korea (N. seoulense, N. leei, and N. boryongense) were analyzed using the partial mitochondrial cytochrome c oxidase subunit 1 (CO1) gene. The adult flukes were recovered from Sprague-Dawley rats (N. seoulense) and newborn chicks (N. leei and N. boryongense) experimentally infected with the neodiplostomula from the grass snake, Rhabdophis tigrinus tigrinus. The genomic DNA was amplified using specific primers, and the sequence of CO1 was obtained. According to the results, the pairwise similarity was 96.1% between N. boryongense and N. seoulense, but was 95.0% between N. boryongense and N. leei and 94.2% between N. leei and N. seoulense. The results demonstrated a closer phylogenetic relationship between N. seoulense and N. boryongense. This high relationship of N. seoulense and N. boryongense may be related to their similar morphologic features including the limited distribution of vitellaria and the presence of a genital cone. N. leei is distinct on the other hand with an extensive distribution of vitellaria and the absence of a genital cone.
