The major blood supply to the femoral head is probably damaged by the fracture of the femoral neck especially when it is a displaced fracture. Complications such as delayed or nonuion of the fracture and avascular necrosis of the femoral head are common. Revascularization after reduction and internal fixation appears to be a slow process and in many patients late segmental collapse occurs. Various techniques have been proposed to restore the blood supply or to improve the circulation to the femoral head. Hereby we performed internal fixation and an autogenous muscle-bone pedicle graft composed of the quadriceps femoris muscle in 3 cases of old, neglected displaced femoral neck fracture. The results seemed to be good in regard to bony union in all 3 cases but it would be needed further follow up study for developing of any avascular necrosis.

STUDY DESIGN: We studied the changes of the adjacent-level after performing anterior cervical interbody fusion. OBJECTIVES: We retrospectively analyzed the radiologic changes such as the degenerative changes and osteophyte formation in the adjacent-level and the affecting factors that affect the changes of the adjacent level after anterior cervical interbody fusion. SUMMARY OF LITERATURE REVIEW: We studied the patients who were more than sixty years old and who had more degeneration at the time of operation and who developed symptomatic new disease within the first four years after their procedure. When the interbody spacer was shortened by 10% to simulate subsidence, the plate lost nearly 70% of its load-sharing capabilities. MATERIALS AND METHODS: All the patients were treated with a plate and an autoiliac bone graft. We reviewed the correlation between the changes in the adjacent level and the factors that included gender, age, the fused segments, the plate-to-disc distance, the preoperative degenerative changes in the adjacent level, subsidence of the graft bone, the height of the graft bone, fracture and dislocation, and loosening of the implant. RESULTS: Radiologic changes in the adjacent-level were seen in 35 cases and these cases included 27 cases in the upper level and 17 cases in lower level. Adjacent level changes were seen in 27 of the 37 (73%) patient who were above 50 years old. Adjacent level changes were seen in 19 (90.5%) of the 21 cases that had preoperative cephalad level degeneration, and adjacent level changes were seen in 9 (81.8%) of the 11 cases that had preoperative caudal degeneration. Adjacent level degeneration developed or increased in the cases of subsidence of a graft over 2 mm. CONCLUSIONS: The patients who undergo anterior cervical interbody fusion need to be continuously followed up because radiologic changes can increase in the case with degenerative change in the adjacent segment and subsidence of the bone graft of more than 2 mm.

Adverse drug reactions can cause considerable discomfort. They can be life-threatening in severe cases, requiring or prolonging hospitalization, impeding proper treatment, and increasing treatment costs considerably. Although the incidence of severe cutaneous adverse reactions (SCARs) is low, they can be serious, have permanent sequelae, or lead to death. A recent pharmacogenomic study confirmed that genetic factors can predispose an individual to SCARs. Genetic markers enable not only elucidation of the pathogenesis of SCARs, but also screening of susceptible subjects. The human leukocyte antigen (HLA) genotypes associated with SCARs include HLA-B*57:01 for abacavir (Caucasians), HLA-B*58:01 for allopurinol (Asians), HLA-B*15:02 (Han Chinese) and HLA-A*31:01 (Europeans and Koreans) for carbamazepine, HLA-B*59:01 for methazolamide (Koreans and Japanese), and HLA-B*13:01 for dapsone (Asians). Therefore, prescreening genetic testing could prevent severe drug hypersensitivity reactions. Large-scale epidemiologic studies are required to demonstrate the usefulness and cost-effectiveness of screening tests because their efficacy is affected by the genetic differences among ethnicities.

There has been a great improvement in height and weight of Korean children owing to economic development over the last 25 years. This study aimed to evaluate the penile length of Korean children today and to compare it with a previous Korean study reported in 1987. The cross-sectional study was conducted with 909 Korean boys aged 0-14 years who had been brought to outpatient clinics of five tertiary hospitals (Busan, Ulsan, and Changwon) between September 2013 and May 2015. The stretched penile length (SPL) was measured and the testicular size was measured using orchidometry (mL). Student's t-test or Mann-Whitney U test was used to compare the result of our study and the study reported in 1987. SPL of Korean children gradually increased from 4.1 ± 0.8 cm at 0-1 year old to 9.6 ± 3.0 cm at 13-14 years old, the most rapidly during the age of 13. While body weight and testicular size significantly increased from 1987 in most of age groups, there were no significant changes in SPL although there was in some age groups. Height decreased in the infants < 1 year old and increased in the children > 6 years old. With the great economic development over the last quarter century in Korea, height, body weight, and testicular size of children significantly increased but there was no significant change in SPL except penile growth pattern.

OBJECTIVES: This study aimed to investigate the correlations between neurological and psychiatric symptoms at two weeks after stroke. METHODS: For 412 stroke patients, stroke severity was evaluated by the National Institutes of Health Stroke Scale (NIHSS), disability by the Barthel Index(BI) and modified Rankin Scale(mRS), cognitive function by the Korean Mini-Mental State Examination(K-MMSE), and muscle power by grip strength. Psychiatric symptoms were assessed by Symptom check list-90-Revision(SCL-90-R), consisted of nine symptom domains : Somatization, Obsessive-compulsive, Interpersonal sensitivity, Depression, Anxiety, Hostility, Phobic anxiety, Paranoid ideation, Psychoticism, and Additional items. The correlations between the neurological and psychiatric symptoms were investigated at the time of admission and before discharge(i.e. before and after treatment). RESULTS: At the time of admission, NIHSS score was associated with scores on Phobic anxiety and Additional items ; and scores on BI and mRS were associated with Depression, Phobic anxiety and Additional items. At the time of discharge, NIHSS score was associated with scores on Somatization, Depression, Phobic anxiety, and Additional items ; scores on BI and mRS were associated with scores on Depression, Phobic anxiety and Additional items ; MMSE score was associated with Obsessive-compulsive, Depression, Phobic anxiety, and Additional items ; and grip strength was associated with Somatization, Depression, Anxiety and Additional items. CONCLUSIONS: More severe neurological symptoms were associated with higher psychiatric morbidity particularly in depression, phobic anxiety, sleep and appetite disturbance at acute stage of stroke. More intensive psychiatric care and intervention are needed for the high risk group.

PURPOSE: The cytotoxicity by 5-fluorouracil (5-FU) is mediated by inhibition of thymi- dylate synthase (TS), which is a rate-limiting enzyme for DNA synthesis. To test whether the resistance to 5-FU would be associated with cellular TS activity, we analyzed TS gene expression from human gastrointestinal cancer cell lines. MATERIALS AND METHODS: We established the experimental conditions for quantitating TS mRNA expression by competitive RT-PCR using mimic DNA. Based on this method, we compared TS mRNA expression between 5-FU resistant cell line and parent cell line and investigated the expression of TS mRNA following 5-FU administration in 6 human gas- trointestinal cancer cell lines. RESULTS: Competitive RT-PCR using mimic DNA seemed to be more effective than Northern blot analysis for quantitation of TS gene expression. The quantity of TS mRNA and IC50 value of 5-FU in 5-FU resistant H630 was found to be 2.5 and 10 times higher than in parent cell line, respectively. And also, we observed linear relationship between TS mRNA level and IC50 value of 5-FU (r 0.76) in 6 gastrointestinal cancer cell lines. CONCLUSION: These results suggest that overexpression of TS mRNA may play a role in the development of 5-FU resistance in human gastrointestinal malignancies

PURPOSE: We conducted this study to examine the clinical results of the proximal metatarsal wedge osteotomy using a single screw fixation and the distal soft tissue procedure in patients with moderate to severe hallux valgus deformity. MATERIALS AND METHODS: Between February 2002 and February 2004, we performed these procedures on 12 patients (15 cases). The 6 cases of all patients had mild to moderate instability in the first MTC (metatarsocuneiform) joint. We estimated the clinical outcomes, the radiological findings and complications. RESULTS: AOFAS score was improved from preoperative 41.5 points to 87.7 points lastly on average. The mean correction angle of HVA and IMA was 23.8 degrees and 6.6 degrees, respectively. The mean position of tibial sesamoid was 2.67 before surgery and 0.87 after surgery. The mean shortening of the first metatarsal bone was 3.07 mm after surgery. There was no pain and complications on the first MTC joint except the breakage of screw in one case and instability of the first MTC joint was improved postoperatively. CONCLUSION: We obtained good clinical and radiographic outcomes in our series. So, proximal metatarsal wedge osteotomy using a single screw fixation and distal soft tissue procedure seems one of the good surgical treatments for moderate hallux valgus deformity.

To evaluate the clinical usefulness of radionuclide(RI) cisternography in patients with hydrocephalus, we retrospectively analyzed RI cisternographic findings of 47 patients by using our classification which was modified from Baum's. and correlated them with CT(n=37) or MRI(n=10) findings and clinical outcome in selected patients with hydrocephalus(n=37). Modified RI cisternographic patterns of 37 patients were type I in three cases(8%), type II in seven(18%), type III-A in six(16%), no case of type III-B, type IV-A in 12(32%), and type IV-B in nine(24%). RI cisternography enabled to differentiate communicating hydrocephalus(27 cases, 73%) from noncommunicating hydrocephalus (10 cases, 27%). There was marked clinical improvement in 17 patients(46%), slight improvement in 11 patients(30%), and no improvement in nine patients(24%). The clinical outcome of patients with RI cisternographic type IV-B was worse than that of other types. CT and MRI could neither predict the clinical outcome nor differentiate type IV-B from Type IV-A(p>.05). Ventricular size index (VSI( was significantly higher in patients with type IV than that with other types(p<.001). RI cisternographic patterns of communicating hydrocephalus were relatively correlated with clinical outcome (r=-0.53, P=.001), VIS(r=0.59, p=.001), and dilatation of fourth ventricle(r=0.41, p<.05). We suggest that our modified classification of RI cisternographic patterns can provide more strict physiological assessment of the CSF dynamics and RI cisternography may be still useful to differentiate communicating hydrocephalus from noncommunicating hydrocephalus and to predict the clinical outcome in conjunction with CT/MR findings and clinical presentation.
