PURPOSE: The solid variety of cerebella r tumors in adult is relatively uncommon. This study is to describe the characteristic MR findings of various solid cerebellar tumors in adult. METHODS: Twenty three cerebellar solid tumors from 22 consecutive patients over age of 15 with surgical confirmations were retrospectively evaluated with MR imaging. H istologic diagnosis included hemangioblastoma (n=6), metastasis (n=6), high-grade astrocytoma (n=3), and medulloblastoma (n=8). The MR findings were reviewed with attention to the size, the signal intensity of the tumors, pattern of enhancement, tumoral margin, degree of peritumoral edema, signal void vascular structures within and/or around the tumor, and location in relation to attachment to the pial surface of the tumor. RESULTS: Solid hemangioblastomas consistently showed slightly low or iso signal intensity on T1 -weighted images and high intensity on T2-weighted images, dense homogeneous enhancement, and signal void vessels within and/or around the mass. Metastatic tumors showed various find ings with predominantly low or iso signal intensity on T2-weighted images. Medulloblastomas was midline and/or paramidline in location, and had larger mass formation. High-grade astrocytomas revealed nonspecific MR findings with no signal void vessels. CONCLUSION: Hemangioblastoma, metastasis, malignant astrocytoma, and medulloblastoma should be included in differential diagnosis of solid cerebellar tumors in adult. Dense homogeneous enhancement and signal void vessels are characteristic of hemangioblastoma. The signal intensity of the tumor, and presence of signal void vessels, location and enhancement pattern can be some value in differential diagnosis of solid cerebellar tumors in adult.

Metastatic tumor to the eye is the most common type of intraocular malignancy. The most common primary site of the intraocular metastatic tumor is the breast in women and the lung in men respectively and the choroid is by far the most common site for intraocular metastasis. We experienced a case of chroidal metastasis in a patient with pancreatic carcinoma which is not published in Korea. So, we review that case with the literatures related with metastatic pancreatic cancer to the choroid.

PURPOSE: The aim of this study was to compare three methods of hernioplasty: high ligation (HL), tissue repair (TR), and tension free (TF) and to determine the usefulness of high ligation for repair of indirect inguinal hernia in young adults. METHODS: One hundred thirty two patients who were under the age of 25 and who underwent repair of their inguinal hernia between January 2001 and December 2005 were reviewed retrospectively by using their inpatient and outpatient records and phone calls. Sixty seven, 23 and 42 patients underwent HL, TR and TF, respectively. The clinical features that were analyzed included location, type, signs and symptoms, operation method, complications and recurrence. RESULTS: The operation times were (mean+/-SD) 46.2+/-19.1, 56.0+/-11.5, and 61.8+/-14.9 minutes for HL, TR and TF, respectively. For the post-operative complications, there was 1 case of wound infection (1.5%) and 1 case of scrotal hematoma (1.5%) for HL; 1 case of wound infection (4.4%) and 1 case of scrotal swelling (4.4%) for TR; 3 cases of wound infection (7.0%), 2 cases of scrotal swelling (4.7%), 1 cases of intermittent pain (2.3%) and 1 case of scrotal hematoma (2.3%) for TF. Two patients in the HL group had recurrences, but there was no recurrence in the TR and TF groups. CONCLUSION: High ligation hernioplasty in young adults showed a shorter operation time, but there were no differences in the rate of complications between the methods. In the case of recurrence, it can be corrected by performing tissue repair or tension free hernioplasty because the normal anatomy may be preserved even after operation. Therefore, high ligation hernioplasty proved to be a useful method for repair of indirect inguinal hernia in young adults. In contrast, for the recurred or older age patients, tissue repair or tension free hernioplasty may be a more useful method.

PURPOSE: There are few reports in Korean literature on the diagnostic efficacy of fine needle aspiration cytology(FNAC) for pediatric cervical lymphadenopathy. This study examined the diagnostic value of FNAC on cervical lymphadenopathy in children. METHODS: Data from 57 pediatric patients(aged 0.3 to 14 years) who underwent FNAC due to cervical lymphadenopathy between January 2001 and March 2005 was reviewed retrospectively. RESULTS: Reactive cervical lymphadenitis was the most common result of the FNAC(52.5 percent). Malignant disease were revealed in 14 percent of all cases. The sensitivity, specificity was 86 percent and 96 percent, respectively. The positive and negative predictive values for malignant disease was 75 percent and 98 percent, respectively. There were two false-positive cases on FNAC; one case of Langerhans cell histiocytosis, and another with infectious mononucleosis. A false-negative case on FNAC was found to be acute lymphocytic leukemia. In seven cases(12 percent), the final diagnosis was confirmed by an open biopsy after the FNAC. There were four FNAC cases where the specimen was not satisfactory for making a diagnosis(7 percent). There were no serious complications of the FNAC procedure. CONCLUSION: FNAC had a high diagnostic efficacy for evaluating children with cervical lymphadenopathy.

BACKGROUND: Alternative medicines may be defined as forms of therapy or examination that have no scientific basis and where no effect or diagnostic reliability have been demonstrated by scientific methods. Many patients with atopic dermatitis try various forms of alternative medicine, and several studies about the use of alternative medicine in the patients of atopic dermatitis were performed in western countries but not in Korea. OBJECT: This study was performed to evaluate the use of alternative medicine in atopic dermatitis patients. METHODS: 188 patients of atopic dermatitis attending our outpatient clinic responded to questionnaires on the use of alternative medicine and the past history of atopic dermatitis. RESULTS: 136 of 188 patients(72%) reported previous or current use of one or more forms of alternative medicine. Herbal remedies(32.4%) were used most frequently, and health food preparations, spa therapy, and diet changes were also commonly used. The most common motif of using alternative medicine was "just want to try every possible treatment"(48.6%) and main information sources were people without same skin disease(relatives and friends)(50.0%). The majority(75.2%) reported they do not use the alternative medicine now because of the poor result. The use of the alternative medicine was related to the disease duration, and the cost of the atopic dermatitis treatment. CONCLUSIONS: The use of alternative medicine in atopic dermatitis is commonplace and should be of concern to dermatologists.

BACKGROUND AND OBJECTIVES: Interleukin (IL)-10 is a major regulator of innate immunity. It interferes with the production of inflammatory mediators by reacting with polymorphonuclear neutrophils, monocytes and macrophages. In addition, it also up-regulates the ex-pression of molecules that amplify the anti-inflammatory effect of IL-10. This study tested the hypothesis that injection of various concentrations of exogenous IL-10 in the middle ear cleft can inhibit the acute stage of otitis media induced by lipopolysaccharide (LPS). And if so, the level of concentration for inhibition can be determined. MATERIALS AND METHOD: IL-10 and/or LPS were injected transtympanically into the middle ear cavity of normal mice. Histopathological measurement of submucosal thickness and num-ber of inflammatory cell infiltration was performed at 24 hours after inoculation of IL-10 and/or LPS. RESULTS: At 24 hours after inoculation, every group of IL-10 inoculation reduced both thickening of the mucous and submucosal infiltration of inflammatory cells in a dose-dependent manner. As the concentrations of IL-10 inoculated increased, mucosal thickness and submucosal infiltration of inflammatory cells were more reduced. CONCLUSION: This study demonstrated that exogenous IL-10 injection into the middle ear can directly reduce LPS-induced otitis media in acute stage in a dose-dependent manner. These findings also indicate that IL-10 may be a candidate for local modulator of acute otitis media.

Migrant workers face challenging working conditions, resulting in physical and mental vulnerability. The objective is to identify their health vulnerabilities and ensure their right to health. Health records of 163 migrant workers (113 males and 50 females) (Group A) and 163 Korean citizens (Group B) visiting our institution were analyzed from August 2021 to July 2022. Both groups underwent urine analysis, chest radiography, and various blood tests. Statistical analysis using independent t-tests and χ2 tests was performed. Group A had a significantly higher rate of hepatitis B virus surface antigen-positive patients, lower vaccination rates for hepatitis B, and poorer nutritional status compared to Group B. Group B generally exhibited higher levels of albumin, glucose, total cholesterol, and thyroidstimulating hormone. There were significant quantitative differences in multiple blood cell and hemoglobin measurements between the two groups. These findings emphasize the need for policy support and public awareness to protect the health rights of migrant workers.

PURPOSE: We retrospectively reviewed clinicopathological characteristics in patients who underwent radical retropubic prostatectomy (RRP) with clinically localized prostate cancer and a biopsy Gleason score of 8 or higher. MATERIALS AND METHODS: Among 266 patients who underwent RRP without prior any neoadjuvant therapy between March 2004 and March 2006, 29 patients had clinically localized prostate cancer and a biopsy Gleason score of 8 or higher. We analyzed several clinicopathologic factors that predict organ-confined disease, and also investigated the impact on postoperative changes of the biopsy Gleason score. RESULTS: Of 29 patients, 12 (41.4%) had organ-confined cancer. Serum prostate-specific antigen (PSA), prostate-specific antigen density (PSAD), tumor volume, and tumor percentage were significant factors for predicting organ-confined cancer (p<0.05). The number of the positive core, percentage of the positive core, sum of the tumor length of the positive core, tumor percentage of total core length, and tumor percentage of the positive core lngth were also significantly higher in the group with an extraprostatic extension compared to the organ-confined cancer group (p<0.05). Of 29 patients, 14 (48.3%) were downgraded to a Gleason score of 7 or less and had a higher chance (64.3%; p=0.016) of experiencing organ- confined disease than those that remained at Gleason scores of 8-10. CONCLUSIONS: Among patients with clinical localized prostate cancer and a biopsy Gleason score of 8 or higher, radical prostatectomy can be considered for primary treatment in some cases with low PSA and PSAD and low predictive volume of the tumor from biopsy results.

PURPOSE: To evaluate postcontrast CT findings of acute pyelonephritis and correlate these with clinical findings and severities. MATERIALS AND METHODS: We retrospectively reviewed the medical records and CT scans of 50 patients with abnormal CT findings among 52 patients of acute pyelonephritis whose postcontrast CT scans had been examined. Fifty cases of acute pyelonephritis were classified into three subgroups on the basis of postcontrast CT findings : Group I (n=20, 40%) wedge-shaped lesions; Group II (n=13, 26%) mass-like lesions; Group III (n=17, 34%) renal abscess formation. In each group, clinical findings and severity were analyzed and correlated with CT findings. The results were statistically analyzed. RESULTS: Although mean values of clinical parameters of group I were lower than those of group II and III with regard to all clinical parameters (including maximal temperature and duration of fever, flank pain, leukocytosis, and admission period), there was no statistically significant correlation among the three groups (p>0.05). All cases were successfully treated with antibiotics only, despite the high rate of abscess formation (34%). CONCLUSION: Acute pyelonephritis spans a continuum of CT findings of varying severity from wedge-shaped or mass-like lesions to multifocal abscesses ; postenhanced CT scan shows high sensitivity (96%) in the detection of acute pyelonephritis. Although the clinical course of groups of mass-like lesions and abscess formation was longer and more severe than that of wedge-shaped lesions, there was no statistically significant clinicoradiologic correlation among the three groups.
