This study was undertaken to evaluate the significant diagnostic points of chronic alcoholic hepatitis (CALH) among clinicopathologic findings observed. The specimens used in this study were 20 cases of CALH and 28 cases of chronic active viral hepatitis (CAVH), which were diagnosed at our University Hospital during 9 years period from 1978 to 1987. In these cases, comparative analysis of age and sex distribution, major clinical manifestations, and laboratory and histopathologic findings was performed. The results obained were summarized as follows: Among 20 cases of CALH, the sex distribution was 15 in male and 15 in female with a ratio of 3:1. The range of age distribution was wide from third to seventh decade. There was no recognizable special point about the age and sex distribution of CALH, compared with cases of CAVH. Major clinical manifestations of CALH were hepatomegaly (85%), jaundice (75%) and abdominal pain (50%). Also there was no recognizable special point about the major clinical manifestations of CALH, compared with cases of CAVH. Abnormal values of major laboratory items in CALH were observed in activities of serum r-GTP (100%), SGOT (95%), SGPT (75%) and serum alkaline phosphatase (60%), and total serum bilirubin (60%). Compared with CAVH in major laboratory findings, the significant diagnostic items of CALH were the activities of serum r-GTP and alkaline phosphatase. The characteristic histopathologic findings of CALH, which were compared with CAVH and observed in liver parenchyma, were fatty change (100%), cytoplasmic ballooning and coagulation (100%), delicate fibrosis (85%), bile stagnation (35%), and Mallory bodies (20%), and that observed blurring of limiting plate (60%) in portal and periportal areas.

We report a case of extraskeletal osteosarcoma in view of rarity, and a brief review of the literature related to this type of tumor is presented. The patient was a 31-year-old Korean woman, who had noticed a bean-sized hard mass in the right thigh progressively enlarged to become egg-size during about 7 months, followed by pain and tenderness. There was neither recognizable previous lesion nor causable agent about the mass on history taking. Physical examination revealed another palpable mass on the inguinal area. The right thigh and inguinal masses were simply excised and histologically confirmed to be an extraskeletal osteosarcoma and metastatic one, respectively.

The cervical spinal injuries may impose a fatal result or permanent neurological disability according to the severity of injury. Authors performed a clinical study consisting of 54 patients who have visited Daejeon Eulji General Hospital for the care of fracture and dislocation of the cervical spine from May 1981 to Jan. 1986, and obtained the following results. 1. The prevalent age distribution was between third and forth decade and the ratio between male and female was 3.5:1 and the most common cause of injury was traffic accident(53.7%). 2. The most common site of injury was CS, 6(22.2%) and the most frequent mechanism of injury was Aexion-rotation type(55.0%). 3. At initial examination, 39 patients(72.2%) had neurological damage and among these, 18 were complete paralysis below the level of injury, 12 were incomplete paralysis, 9 were nerve root injuries. 4. Operative treatment was performed on 24 patients, these were Rogers' posterior fusion on 19 patients, Brooks and Jenkins' atlantoaxial fusion on 3 patients, occipitocervical fusion on 1 patient and excision of hactured fragment on 1 patient. 5. There were no evidences of neurological recovery in completely paralyzed patients, but among incompletely paralyzed and nerve root injured patients, neurological recovery was found in 57.1% of conservatively treated patients and in 71. 4% of operated patients. 6. Radiological stability was found in entire patients who received operative treatment, but, in conservatively treated patients, remained 1 late instability.

As the span of life is prolonged by socioeconomic and medical development, the percentage of the geriatric population is increasing annually. Now, surgical therapy for the geriatric patients is an important area of medicine. To understand the clinical significance of surgical geriatric patients, an analysis was made of the records at the Surgical Department of City hospital, East Seoul, for 182 patients over 65 years of age, who were treated from January 1990 through December 1995. The results are as follows: 1) The number of surgical patients admitted during the 6 years was 2,734, and the number of surgical geriatric patients admitted during the same period was 257 patients (9.4% of all surgical patients). The percentage of geriatric patients show an increasing tendency from 8.1% in 1994 to 11.3% in 1995. 2) The sex distribution was 140 male patients (54.5%) and 117 female patients (45.3%), a ratio of 1 : 0.83. 3) The average duration of admission was 18.2 days and durations of admission of less than 1 week were most common (21.8% of all geriatric admissions). 4) Of the 182 cases treated surgically, 139 cases (76.4%) involved general anesthesia, 32 cases (17.6%) anesthesia administered spinally, and 11 cases (60%) local anesthesia; One hour or less of general anesthetic time was most common (41.7%). 5) Malignant disease was found in 46 patients (25.3%); stomach cancer was the most frequently found malignant disease. Non-malignant disese was found in 136 patients (74.7%); appendicitis was the most frequently found non-malignant disease. 6) Coexistent disease was noticed in 108 patients (59.3%); cardiovascular disease was the most frequently found (27.1%), and chronic pulmonary disease (21.3%) and hypoproteinemia (14.2%) were next. 7) Operations were performed on 182 patients of the total 257 patients, operation rate of 70.8%. The old age group had a low operation rate. 8) Postoperative complications were occurred in 43 cases (23.6%), and operative mortality was 2.7%. The significant factors affecting postoperative morbidity and mortality were malignancy, long duration for the general anesthetic time, coexistent disease, and emergency operation. The results suggest that the number and the rate of surgical geriatric patients have increased and that age has little effect on the postoperative prognosis. Thus, we believe that more active preoperative treatment, complete therapy for coexistent disease, execution of elective surgery and a short anesthetic time for intentional surgery are important factors for decreasing postoperative morbidity and mortality for surgical geriatric patients.

BACKGROUND: Silver has been used for disinfection and sterilization. We aimed to confirm the in-vitro antibacterial effects of nanocrystalline silver-coated gauze. METHODS: Fourteen clinical isolates each of Escherichia coli and Acinetobacter baumannii were used. Bacterial suspensions made in tryptic soy broth were exposed to Ordinary and silver-coated gauze. Bacteria were then harvested from the gauze immediately and after 24 h incubation, cultured on blood agar plates and eunmerated for viable counts. The number of colonies was converted into common logarithms for comparison. RESULTS: The number of colonies recovered from silver-coated gauze was significantly lower than those recovered from ordinary gauze when harvested immediately after exposure (E. coli, 3.06 vs 1.73; A. baumannii, 3.13 vs 1.98; P<0.001). After 24 h incubation of exposed gauze, silver-coated gauze produced less than 1 CFU/mL, whereas ordinary gauze produced a number of colonies significantly higher than it did immediately after exposure (E. coli, 4.13; A. baumannii, 4.46; P<0.001). Conclusion: Compared with ordinary gauze, silver-coated gauze was shown to have 99.99% antibacterial effect.

Strumal carcinoma of the ovary is rare tumor of germ cell origin characterized by intimate mixture of thyroid tissue and carcinoid. We report a strumal carcinoid tumor associated with ipsilateral follicular cyst and contralateral mature cystic teratoma of the ovary in a 47-year-old woman. Histologically it was composed largely of trabeculae partly of insular carcinoid and focally of individual thyroid follicles. Many cells in the carcinoid areas and even some follicular areas contained abundant argyrophile granules, and they also, in the corresponding areas, demonstrated thyroglobulin. Electron microscopic findings revealed abundant neurosecretory granules and colloid material in the same cell. We agree that this tumor is derived from hybrid showing thyroid and neuroendocrine differenciation.

PURPOSE: There has been little research regarding the effectiveness of oseltamivir for influenza B infections. We sought to identify the different clinical manifestations between patients treated with and without oseltamivir. METHODS: We retrospectively studied the medical records of 72 inpatients or outpatients from two medical centers diagnosed with influenza B infections by either a rapid antigen test or multiplex reverse transcriptase PCR between January 2012 and July 2012. We compared gender, age, past medical history, admission period, total fever duration, fever duration after hospitalization, post-oseltamivir medication peak temperature, laboratory test, chest X-ray, antibiotic medication, and the presence of concomitant viral or bacterial infections. RESULTS: The number of subjects in our study was 72 who were diagnosed with influenza B pneumonia, acute bronchitis, acute bronchiolitis, croup, and mean age was 3.6+/-2.8 year old. The demographic characteristics and clinical manifestations of oseltamivir and the non-oseltamivir groups, including hospitalization period (4.18+/-2.10 vs 4.79+/-1.49 days, P=.17) and total fever duration (5.32+/-2.07 vs 6.41+/-3.25 days, P=.09), demonstrated no significant differences. Notably, the oseltamivir group did have significantly reduced usage of antibiotic treatment than the non-oseltamivir group (P=.04). When we limited our patient group to patients under the age of three, similar results were seen. The group prescribed oseltamivir within 48 hours of fever onset had less antibiotic usage, in addition to a shorter fever duration. CONCLUSION: Oseltamivir appeared to have no benefit in improving the clinical course. However, if it is prescribed within the first 48 hours of symptoms, it may be more effective.

The CD8(+)CD28(+) T cells have known to mediate major histocompatibility complex class I-restricted cytolysis and to secret an HIV-1 inhibitory factor. As HIV infection lead to dramatic changes within the cellular immune system, the cellular cytotoxicities decrease in the duration of the HIV infection. To determine the importance of the cellular cytotoxicities in long-term nonprogression, we tried to compare CD28 expression on total T, CD4(+) T, and CD8(+) T cells as one of methods for cellular cytotoxicity measurements between long-term nonprogressor and normal person or between long-term nonprogressor and rapid progressor. The median percentages and counts of CD4(+) T cells of the norrnal, the long-term nonprogressor, and the rapid progressor groups were 39.9 and 0.96 * 10(9) cells/L, 24.6 and 0.58 * 10(9) cells/L, 9.9 and 0.15 * 10 cells/L, respectively. As a result of comparison of the cells having CD28 surface molecules on CD8(+) T cells in the long-term nonprogressor and the rapid progressor group, they showed over 5 times lower than that in the normal group. Especially, the long-term nonprogressor regarded to the healthy HIV-infected patient showed much lower CD28 expression on total T, CD4(+) T, and CD8(+) T cells than those of the normal person. The proportions of CD4'CD28 T and CD3CD28 T cell subsets showed the significant difference between the LTNP and the RP group. In conclusion, although HIV-infected patients were LTNPs having the steady CD4(+) T cell counts and no clinical symptoms, we suggested that HIV led to abnormality within the lymphocyte subsets such as the altered expression of CD28 molecules on various T cell subsets and this result would cause deficiency of host immune function and failure of control of HIV replication by anergy in T cell subsets.
