Malignant osteoblastoma is very rare tumor which shows histological findings of an aggressive pattern and benign clinico-radiological features, and also called as aggressive or pseudomalignant osteoblstoma. The authors experienced one csse of malignant osteoblastoma involving diaphysis of left humerus in 22-year old man. The patient is healthy and maintains his normal activity without recurrence over five years after complete excision of cystic mass, curettage and bone graft.

Nowday, ionizing radiation is one of the methods eradicating the uterine cervical malignancy. However radiation alone or in combination with surgery have an effect on normal tissue as well as the malignant cells, and their changes have been well described in other countries. Unfortunately, the history of radiation modality for cancer treatment is relatively short and the reports about radiation induced changes are limited in our country. We evaluated the radiation-induced changes in cervico-vaginal smears of 107 uterine cervical cancer patients obtained from March, 1985 to October, 1987. Most patients had been received 5,400 Rads of external radiation and intracavitary radiation. Patient's age ranged from 30 to 67 years old. Of 107 cases, 24 cases were normal, 72 cases showed benign radiation changes, 7 cases revealed radiation dysplasia, and residual and recurrent carcinomas found in one and 3 cases, respectively. Cytoplasmic and nuclear enlargement were the most common and noted in 57 and 38 cases, respectively. Vacuolization and polychromasia of the cytoplasm were identified in 43 and 30 cases, respectively. The most common histiocytic change was multinucleation, which was found in about one third. The radiation changes of the cytoplasm and nuclear enlargement persisted for a long time after completion of radiation, however, nuclear degeneration and multinucleation gradually disappeared after 6 months. The inflammation in background prolonged for a long time but degeneration disappeared after 6 months. The biologic significance of post-radiation dysplasia could not evaluated because of short follow up period.

BACKGROUND: We conducted this study to describe the epidemiology of community-acquired bacteremia and identify its prognostic factors. MATERIALS AND METHODS: All patients admitted to a community-based tertiary hospital with community-acquired bacteremia from June 2002 to May 2004 were included and analyzed retrospectively. RESULTS: During the study period, clinically significant community-acquired bacteremia occurred in 223 patients with the frequency of 5.3 patients per 1,000 patient-admission. The commonly isolated organisms were E. coli (47.1%), K. pneumoniae (13.0%), S. aureus (8.1%), and S. pneumoniae (4.5 %). The leading source of bacteremia were urinary tract infection (34.5%), intraabdominal infection (33.6%), primary bacteremia (10.3%), and skin & soft tissue infection (8.1%). The overall mortality was 17%. S. aureus (34.8%) and K. pneumoniae (30.4%) were two major organisms of primary bacteremia with high case fatality of 50% and 28.6%, respectively. Univariate analysis showed that the followings were associated with significant increase in mortality: male patient; S. aureus and other streptococci bacteremia; increasing APACHE II score; definite diagnosis after 3 days of admission; inappropriate antibiotics therapy within 24 hours of admission; emergency room; admission to ICU. The independent predictors of mortality were male patient (RR 3.02, P=0.031), increasing APACHE II score (RR 1.12, P=0.011), and admission to ICU (RR 9.73, P<0.001). CONCLUSION: Rapid definite diagnosis and prompt administration of appropriate antibiotics according to the local epidemiologic pattern are the most important controllable factors for the better outcome.

Cavernous angiomas are considered to be congenital in origin. Patients under age of 14 years usually does not require imaging because they are likely to have a benign abducens nerve palsy, unless they develop additional signs or symptoms of neurologic disease during observation. Here we report a case of an isolated abducens nerve palsy caused by overt hemorrhage from de novo formation of cavernous angioma in the pons. Cavernous angiomas of the brain stem should be considered as a possible cause of isolated abducens nerve palsy in young adult and MRI, including gradient-echo sequences should be performed.
