The anthors studied the 152 cases of primary bone tumors statistically during the period of 7 years and 4 months from Janusry, 1980 to April, 1987 at the department of orthopaedic surgery, St. Benedict Hospital, Pusan and the department of anatomic pathology, Pusan National University Hospital. The results of the study were summsrized as follows; l. Of the 152 cases of primary bone tumors, benign tumors were 128 cases(84.2%) and malignant tumors were 24 cases(15.8%). 2. Of benign bone tumors, the most common type was osteochondroms(34 cases, 26.6%), followed by fibrous dysplasia(25 cases, 19.5%), giant cell tumor(14 cases, 10.9%) and enchondroma(11 cases, 8.6%). 3. Of malignant bone tumors, the most common type was osteosarcoma(14 cases, 58.3%), followed by chondrosarcoma(5 cases, 20.8%), Ewing's sarcoma(3 cases, 12.5%) and myeloma(1 case, 4.2%). 4. Age distribution of benign bone tumors showed that most cases(76.4%) occured under 30-years old. Among malignant bone tumors, most of osteosarcoma and Ewing's sarcoma occured between 10-and 20-yesrs old. 5. The male to female ratio of overall benign bone tumors was 1.1: 1, and that of maligant bone tumors was 1.2: 1. There was no sexual difference. 6. The favorite sites of benign bone tumors were femur(31 cases, 23.1%), maxilla or mandible(31 cases, 23.1%), tibia(22 cases, 16.4%) and rib(11 cases, 8.2%) and those of malignant bone tumors were freguently femur(12 cases, 50.0%), followed by tibia(5 cases, 20.8 %) and pelvis(4 cases, 16.7%). 7. The most frequent manifestations in benign bone tumors were mass or swelling(62.7%), followed by pain or tenderness(33.9%) and disturbed motion or function(10.2%), but those were mostly pain or tenderness(73.9%), followed by mass or swelling(52.2%) and pathologic fracture(13.0%) in malignsnt bone tumors.8. The duration of symptoms in benign bone tumors was less than 6 months in 39.1% and less than 1 year in 44.6%, but less than 6 months in 70.9% and less than 1 year in 87.6% in malignant bone tumors. The duration of symptoms in malignant bone tumors was much shorted than that of benign bone tumors.

The glucose uptake rate by plerocercoid of Diphyllobothrium sp. was a mean value of 5.35+/-0.80 micro-mole/hr/g of wet wt, and total CO(2) production rates by the plerocercoid larva averaged 7.54+/-0.73 micro-mole/hr/g of wet wt. The relative specific activity into respiratory CO(2) showed a mean value of 7.30 +/-0.90 per cent. The rate of CO(2) production derived from medium C(14)-glucose was a mean of 0.58+/-0.13 micro-mole/hr/g of wet wt. Therefore, the average value of 1.92+/-0.38 per cent of glucose utilized by the larvae from the medium C(14)-glucose was oxidized to respiratory CO(2). The tissue concentration of glycogen in plerocercoid larva was a mean of 46.28 +/-2.23 mg/g or 4.63+/-0.22 per cent/g of wet wt., and the turnover rate of glycogen pool was a mean of 0.049 +/- 0.012 %/hr or 0.010 +/- 0.003 mg/hr/g of wet wt. The average value of 2.76+/-1.00 per cent of glucose utilized by the larvae from the medium C(14)-glucose was incorporated to the glycogen. These data accounts for that only 5 per cent of the utilized glucose by the plerocercoid larvae participated in furnishing the oxidation into respiratory CO(2) and the synthetic process into glycogen.

Soil-transmitted helminthiases (STH) are now no longer public health problems in the Republic of Korea (South Korea), but their status are unavailable in the residents of North Korea (NK) despite the expectation of large scale traffic and future reunification of the Korean Peninsula. A total of 20 female refugees from NK who had been admitted to the Division of Gastroenterology, Dankook University Hospital, were subjected in this study. Among them, 15 refugees were examined by the colonoscopy and 10 ones were examined with the stool examination (formalin-ether sedimentation). Both diagnostic methods were commonly adopted in 5 patients. Eggs of Trichuris trichiura were detected in 7 out of 10 refugees in the stool examination. In the colonoscopy, T. trichiura worms were found in 6 (40.0%) out of 15 refugees. Total 9 (45.0%) peoples were confirmed to be infected with human whipworms. Additionally, 1 case of clonorchiasis was diagnosed in the stool examination and a worm of Ascaris lumbricoides was discovered from a trichuriasis case. These findings suggested that STH is highly prevalent in NO, in which living conditions are not so good in the aspect of general hygiene and medical care.

BACKGROUND: As the size of the elderly population has increased compared to the hole, there has been growing concern over potential health problems and geriatric hospitals for elderly people. However, despite the emerging needs for geriatric hospitals, there is no data on the clinical characteristics of patients being admitted to geriatric hospitals. To analyze the characteristics of elderly patients admitted to a geriatric hospital, we studied the medical records of patients admitted to Yong-in Hyoja Geriatric Hospital during a recent 20 months period. By clarifying the clinical characteristics of elderly patients admitted to a geriatric hospital, the basic data for understanding and treating elderly patients could be made. METHODS: We analyzed the medical records of 345 patients who were admitted to Yong-in Hyoja Geriatric Hospital from November 1997 to July 1999. The diagnosis of patients was largely subgrouped according to the existence of dementia, and subsequent detailed diagnoses were made. RESULTS: (1) The average age of patients was 74.59 years and there were slightly more females than males admitted (ratio, 1.15:1). (2) Most of the patients suffered from dementia (62.1%), of which vascular dementia was the most common(31.6%), followed by Alzheimer dementia(19.15%). (3) Compared to vascular dementia, patients with Alzheimer dementia had more severe cognitive dysfunction, psychosis, and agitation, while patients with vascular dementia had more problems in activities of daily living (ADL) and were more depressed than Alzheimer dementia (4) The average hospitalization duration was 3.54 months and incidence of significant illness after admission was 29.8%. The mortality rate was 10.9%. (5) The most common cause of death was infection (45.2%), followed by cardiovascular problems(16.2%). CONCLUSIONS: In addition to significant illnesses and mortality after admission, most patients admitted to geriatric hospitals have severe cognitive and behavioral problems. Therefore, adequate medical and neurological assessment and treatment for the aged is necessary.

PURPOSE: We analyzed the surgical and functional outcomes of 100 consecutive laparo-scopic radical prostatectomies (LRP) performed by a single surgeon. MATERIALS AND METHODS: Between October 2007 and May 2010, a total of 100 consecutive patients underwent LRP for prostate cancer at our institution. We retrospectively reviewed the medical records of these patients to determine surgical and functional results. We compared surgical and functional outcomes between three groups divided on the basis of operation period (Group 1; first 40 cases; Group 2; next 30 cases; Group 3; last 30 cases). RESULTS: The operative time decreased significantly as the surgeon's experience increased over time (P<0.01). The learning curve for operative time was surpassed after approximately 40 cases. The overall positive surgical margin (PSM) rate was 17.5% in Group 1, 16.7% in Group 2, and 10% in Group 3. For organ-confined disease, the PSM rate was 2.5%, 6.7%, and 3.3% in Groups 1, 2, and 3, respectively. The continence rate (absence of a pad) was 73.2% and the social continence rate was 94.7% at 12 months after surgery. There was a significant difference in continence (absence of pad) between the early (Group 1) and late group (Group 3) at 1, 3, and 6 months (P<0.0001). The continence rate was not affected by whether the pubic bone-anchoring procedure or the Rocco suture method was used. The overall potency rate was 16.7% and 48.6% at 6 and 12 months, respectively. For bilateral nerve-sparing cases, the potency rate was 20% and 57.1% at 6 and 12 months, respectively. CONCLUSIONS: Our surgical and functional outcomes indicate that even in this 'robotic era', LRP is still an attractive treatment option for patients with localized prostate cancer, especially in areas with limited access to surgical robots.

BACKGROUND/AIMS: To prevent the transmission of pathogens by endoscopes, following established reprocessing guidelines is critical. An ideal reprocessing step is simple, fast, and inexpensive. Here, we evaluated and compared the efficacy and safety of two disinfectants, a tertiary amine compound (TAC) and ortho-phthalaldehyde (OPA). METHODS: A total of 100 colonoscopes were randomly reprocessed using two same automated endoscope reprocessors, according to disinfectant. The exposure time was 10 minutes for 0.55% OPA (Cidex® OPA, Johnson & Johnson) and 5 minutes for 4% TAC (Sencron2®, Bab Gencel Pharma & Chemical Ind. Co.). Three culture samples were obtained from each colonoscope after reprocessing. RESULTS: A total of nine samples were positive among the 300 culture samples. The positive culture rate was not statistically different between the two groups (4% for OPA and 2% for TAC, P=0.501). There were no incidents related to safety during the study period. CONCLUSIONS: TAC was non-inferior in terms of reprocessing efficacy to OPA and was safe to use. Therefore, TAC seems to be a good alternative disinfectant with a relatively short exposure time and is also less expensive than OPA.

OBJECTIVE: A groove technique for securing an electrode connector was described as an alternative surgical technique in deep brain stimulation (DBS) surgery to avoid electrode connector-related complications, such as skin erosion, infection, and migration. METHODS: We retrospectively reviewed 109 patients undergoing one of two techniques; the standard technique (52 patients using 104 electrodes) and the groove technique (57 patients using 109 electrodes) for securing the electrode connector in DBS surgery, regardless of patient disease. In the standard percutaneous tunneling technique, the connector was placed on the vertex of the cranial surface. The other technique, so called the groove technique, created a groove (about 4 cm long, 8 mm wide) in the cranial bone at the posterior parietal area. Wound erosion and migration related to the connectors were compared between the two techniques. RESULTS: The mean follow-up period was 73 months for the standard method and 46 months for the groove technique. Connector-related complications were observed in three patients with the groove technique and in seven patients with the standard technique. Wound erosion at the connector sites per electrode was one (0.9%) with the groove technique and six (5.8%) with the standard technique. This difference was statistically significant. The electrode connector was migrated in two patients with the groove technique and in one patient with the standard technique. CONCLUSIONS: The groove technique, which involves securing an electrode using a groove in the cranial bone at the posterior parietal area, offers an effective and safe method to avoid electrode connector-related complications during DBS surgery.

Liposarcoma is one of the most common soft tissue sarcoma of adult life. Among soft tissue sarcoma its incidence ranges from 10% to 12%, and its two major sites are the extremities and the retroperitoneum. Liposarcoma is remarkable because of its frequent large size, variable histological picture, and high recurrent rate. We report a case of recurrent retroperitoneal liposarcoma in a 38-year-old woman who was treated with radical nephrectomy including tumor excision in August 1988. Four and half years after the first operation, she was diagnosed as recurrent retroperitoneal liposarcoma and treated by tumor excision. Six months after the second operation, presented with the second recurrent retroperitoneal tumor, she underwent tumor excision and radiation therapy and she is under being followed up.
