Purpose:
This study examined the changes in the body mass index (BMI) and the effects of BMI on the knee function and risk factors for an increase in BMI after total knee arthroplasty (TKA) in Asians.
Materials and Methods:
A prospective observational study was conducted on 100 cases of TKA performed by one surgeon. Obesity was defined as BMI ≥25 kg/m 2 . The BMI and Knee Society Score, consisting of the Knee Score and Function Score, were measured on the day before surgery and one year after surgery.
Results:
The BMI decreased or was maintained in 34 cases (34%) and increased in 66 cases (66%) one year after surgery. An increase in BMI of 5% or more was considered a clinically significant increase in BMI and occurred in 28 cases (28%). The patients with an increased BMI by more than 5% showed a significantly lower knee function score. The age and preoperative function score were significantly associated with an increased BMI by more than 5%. As the age increased by one year, the odds ratio at which the BMI would increase by more than 5% one year after surgery was 0.905. Moreover, as the preoperative function score increased by one point, the odds ratio that the BMI would increase by 5% one year after surgery was 0.902. In other words, a younger preoperative age and a lower preoperative function score mean a higher risk of a more than 5% postoperative increase in BMI.
Conclusion
The BMI increased by more than 5% one year after surgery in 28% of the TKA patients examined. They had a lower functional score. The risk factors for a more than 5% increase in BMI after TKA were young age and a low preoperative function score. Therefore, surgeons should educate patients, particularly those who are young or have a low preoperative function score, so that the patient’s BMI would not increase after surgery.

Acarid mites were isolated from samples collected in Seoul during the period of October 1975 to August 1978. Samples consisted of stored foods such as rice, flour, sugar, dried fishes, dusts of houses and freight offices. The identified mites were classified into 12 species belonging to 12 genera, 5 families as following lists, of which 4 species (*) are newly recorded in Korea. Family Acaridae Ewing and Nesbitt, 1942: Tyrophagus putrescentiae (Schrank, 1781). Acarus siro Linnaeus, 1758. Aleuroglyphus ovatus* Troupeau, 1879. Suidasia nesbitti Hughes, 1948.

BACKGROUND: External ventricular drainage (EVD) is an important procedure for draining excessive cerebrospinal fluid (CSF) and monitoring intracranial pressure. Generally, EVD is performed in the operating room (OR) under aseptic conditions. However, in emergency circumstances, the operation may be performed in the intensive care unit (ICU) to save neuro-critical time and to avoid the unnecessary transfer of patients. In this study, we retrospectively analyzed the risk of EVD-induced CNS infections and their outcomes according to the operating place (ICU versus OR). In addition, we compared mortalities as well as hospital and ICU days between the CNS infection and non-CNS infection groups. METHODS: We reviewed medical records, laboratory data and radiographic images of patients who had received EVD operations between January, 2013 and March, 2015. RESULTS: A total of 75 patients (45 men and 30 women, mean age: 58.7 +/- 15.6 years) were enrolled in this study. An average of 1.4 catheters were used for each patient and the mean period of the indwelling catheter was 7.5 +/- 5.0 days. Twenty-six patients were included in the ICU group, and EVD-induced CNS infection had occurred in 3 (11.5%) patients. For the OR group, forty-nine patients were included and EVD-induced CNS infection had occurred in 7 (14.3%) patients. The EVD-induced CNS infection of the ICU group did not increase above that of the OR group. The ICU days and mortality rate were higher in the CNS infection group compared to the non-CNS infection group. The period of the indwelling EVD catheter and the number of inserted EVD catheters were both higher in the CNS infection group. CONCLUSIONS: If the aseptic protocols and barrier precautions are strictly kept, EVD in the ICU does not have a higher risk of CNS infections compared to the OR. In addition, EVD in the ICU can decrease the hospital and ICU days by saving neuro-critical time and avoiding the unnecessary transfer of patients. Therefore, when neurosurgeons decide upon the operating place for EVD, they should consider the benefits of ICU operation and be cautious of EVD-induced CNS infection.

In an open reduction of the mandibular angle fracture, it is crucial to approximate each fracture segment as closer as possible for the reduction of the healing period. In this case report, we proposed a new technique for the mandibular angle fracture. This was designed to minimize the gap between two separated segments using mini-implants and surgical wires. Mini-implants were placed around the fracture line, followed by wire ligation to minimize the fracture gap. And then internal fixation was easily employed with plates and screws. The advantages of this technique were reduced time for operation, the promotion of healing, rapid functional recovery, and few complications.

A 32-year-old housewife who resides in Taegu was admitted in Yeungman University Hospital due to right upper quadrant abdminal pain of 2 mounths'duration. An abdomical CT and ultrasonography revealed a relatively well demarcated low density mass in the right lobe of liver. Right hepatic lobectomy was performed on the clinical impression of hepatoma. On the light microscopic study, the lobulated liver mass showed extensive central necrosis and fibrosis, with large numbers of pseudotubercles therein. The pseudotubercles have distorted helminthic eggs frequently. The submitted common bile duct lymph node also showed a few pseudotubercles. The eggs recovered from the tissue homogenate measured 140~152 micrometer by 75~85 micrometer in size and were unembryonated and light yellow to brown. The eggs were determined as those of Fasciola species. We reported the present case as 11th one of human fascioliasis in korea.

OBJECTIVE: The aim of this study was to investigate whether embryonic stem (ES) cells can be established from isolated blastomeres of mouse embryos. METHODS: Blastomeres were separated from mouse (C57Bl/6J) 2- or 4-cell embryos. Isolated blastomeres or whole 4-cell embryos were co-cultured with mitosis-arrested STO feeder cells in DMEM supplemented with recombinant murine leukemia inhibitory factor and ES-qualified fetal bovine serum. After the tentative ES cell lines were maintained from isolated blastomeres or whole embryos, some of them were frozen and the others were sub-cultured continually. Characteristics of tentative ES cell lines as were evaluated for specific gene expressions with immunocytochemistry and RT-PCR. RESULTS: One ES cell line (3.0%) was established from isolated blastomere of 2-cell embryo and one cell line (4.0%) from isolated two blastomeres of 4-cell embryo. And five cell lines (16.7%) were established from whole 4-cell embryos. Both cell lines from isolated blastomere and whole embryo expressed mouse ES cells specific markers such as SSEA-1, Oct-4 and alkaline phosphatase. Marker genes of three germ layers were expressed from embryoid bodies of both cell lines. CONCLUSION: This study suggests that mouse ES cells could be established from isolated blastomeres, although the efficiency is lower than whole embryos. This animal model could be applied to establishment of autologous human ES cells from biopsied blastomeres of preimplantation embryos in human IVF-ET program.
