Colposcopic examination and biopsy were performed on 197 patients with abnormal cervical cytology. The patients subsequently underwent electrocoagulation, LLETZ, conization and hysterectomy depending on their diagnosis from January, 1989 to December, 1994. The comparison between the diagnosis of cytology and that of colposcopic biopsy showed fair agreement with only 35% of cases(K=20%). The abnormal lesion was underestimated by cytology in 49.7% of cases. Thirty three cases(16.8%) were threated by LLETZ. Histological comparison between the colposcopic biopsies and LLETZ samples showed fair agreement with 39% of cases (K=25%). 5 cases(15%) of the colposcopic biopsy have been underestimated when compared to the LLETZ histology. Sixty two cases were done conization after colposcopic biopsy. Histological comparison between the colposcopic biopsies and conization samples showed fair agreement with 59% of cases(K=38%). The colposcopic biopsies were underestimated in 24.2% of cases compared to the cone biopsy specimen. The correct diagnosis rates of colposcopic biopsy of dysplasia, carcinoma in situ, and microinvasive carcinoma were 70%, 82%, and 20% respectively. (continue)

Peritonitis is a common and potentially serious infection in patients undergoing continuous ambulatory peritoneal dialysis (CAPD). The most common organisms usually associated with CAPD peritonitis are Staphylococcus aureus and Staphylococcus epidermidis. Rarely, aerobic gram negative bacilli have been the causative agents of CAPD peritonitis. The treatment of CAPD peritonitis requires removal of the peritoneal catheter and treatment with parenteral antibiotics active against the causative pathogen. While hospitalized for CAPD peritonitis, a 55-year-old man on CAPD had nosocomial peritonitis secondary to infection by ESBL-producing E.coli, that was sensitive to imipenem and meropenem. He was treated successfully with a 4-week course of intraperitoneal meropenem therapy without subsequent relapse, loss of peritoneal catheter, ultrafiltration failure, or dialysis inadequacy.

PURPOSE: Resistance to anticancer chemotherapeutic drug remains a major obstacle in cancer chemotherapy. Multidrug-resistance(MDR) gene overexpression and detoxification by glutathione are believed to be involved in adriamycin and cisplatin resistance. We investigated change of p-glycoprotein(MDR gene product) expression, cellular glutathione content and glutathione peroxidase and glutathione transferase activities by hyperthermia to elucidate the synergistic mechanism of hyperthermia with chemotherapeutic agent. MATERIALS AND METHODS: Human renal cell carcinoma cell lines, Caki-1 and A-498 were used. Control temperature was 37OC and hyperthermia of 43OC was applied in 2 and 4 hours durations. P-glycoprotein expression was measured by flowcytometric examination using monoclonal antibody to p-glycoprotein. Glutathione content and activities of glutathione peroxidase and transferase were measured by biochemical methods. RESULTS: Glutathione content and activities of glutathione peroxidase and transferase were not changed by hyperthermia. However, p-glycoprotein expression was reduced by hyperthermia of 43OC. CONCLUSIONS: These results suggest that reduced p-glycoprotein expression by hyperthermia causes increased intracellular accumulation of chemotherapeutic agent by decreasing drug efflux mechanism and plays an important role in synergistic effect with adriamycin and cisplatin cytotoxicities.

PURPOSE: It is well known that smoking is one of the most important etiologic factor in bladder cancer and mutations of p53 tumor suppressor gene are the important step in carcinogenesis of urinary bladder. In this study, we investigated the difference in pattern and rate of p53 gene mutation between smoker and non-smoker MATERIALS AND METHODS: Of 26 bladder transitional cell carcinoma, 16 cases were smoker and 10 cases were non-smoker. We evaluated mutation of the p53 gene concentrated on axon 5 through 8, using polymerase chain reaction- single strand conformation polymorphism(PCR-SSCP) with radioisotope. RESULTS: 3 cases(18.7%) of 16 smoker were found to have p53 gene mutation, but none of 10 non-smoker was found. 2 of 3 cases of p53 gene mutation were found in exon 5 and 1 in exon 7. The pattern of p53 gene mutation was different in 3 cases. CONCLUSIONS: Although the more cases will be needed in this study, we think that a mutation of p53 in bladder cancer may be associated with cigarette smoking.

Purpose:
To evaluate the effect of lacrimal endoscopy on operation time in silicone tube intubation for patients with nasolacrimal duct obstruction.
Methods:
We conducted retrograde chart review of 168 eyes of 107 patients who were diagnosed with acquired nasolacrimal duct obstruction and underwent silicone tube intubation from January 2019 to February 2023. We analyzed relationship between use of lacrimal endoscopy and operation time, and effect of operation time on success rate of surgery according to use of lacrimal endoscopy.
Results:
Of 168 eyes, 58 eyes underwent silicone tube intubation with lacrimal endoscopy, and 110 eyes underwent silicone tube intubation without lacrimal endoscopy. Average operation time was 10.98 ± 2.24 minutes in the group with lacrimal endoscopy, and 12.44 ± 4.08 minutes in the group without lacrimal endoscopy. Operation time in the group with lacrimal endoscopy was relatively shorter and statistically significant (p = 0.003). When analyzing correlation between operation time and success rate, success rate decreased by 0.877 times when operation time increased by 1 minute in the entire group, and there was statistical significance (p = 0.022). There was no statistical significance in the correlation between operation time and success rate in the group with lacrimal endoscopy. And in the group without lacrimal endoscopy, success rate decreased by 0.865 times when operation time increased by 1 minute, and there was statistical significance (p = 0.019).
Conclusions
In silicone tube intubation for nasolacrimal duct obstruction, Lacrimal endoscopy is considered an effective treatment that can shorten operation time and prevent complications while accurately diagnosing cause and extent of obstruction by investigating the inside of the nasolacrimal duct.

Cholesteatoma of the upper urinary tract is a rare nonmalignant condition histologically characterized by keratinizing desquamative squamous metaplasia (KDSM). Until now about 80 cases including one case from Korea have been reported. Cholesteatoma shows microscopic features of squamous metaplasia of the transitional epithelium and keratinization. These changes with subsequent desquamation of the superficial epithelial layers explain clinical manifestations of the disease. Flank pain, passage of cornified material in the urine and a filling defect on the IVP constitute the characteristic triad. Most cases were managed by extensive ablative surgery for fear of malignant potential. We report a case of renal cholesteatoma which was misdiagnosed as renal stone in 58 year-old female patient who had been suffered from intermittent left flank pain.

PURPOSE: To evaluate the clinical and radiological results, as well as the survival rate, associated with total hip arthroplasty using a hydroxyapatite (HA)-coated anatomical femoral stem at a follow-up of > or =12 years. MATERIALS AND METHODS: From April 1992 to May 1997, 86 patients (102 hips) underwent total hip arthroplasty with a HA-coated ABG I (Anatomical Benoist Giraud; Howmedica) hip prosthesis. The average age at the time of surgery was 53.4 years and the mean duration of follow-up was 17.1 years (range, 12.1-21.0 years). The Harris hip score (HHS) and radiographic assessments of thigh pain were used to evaluate the clinical results. We observed osteointegration, cortical hypertrophy, reactive line, calcar resorption and osteolysis around the femoral stems. The survival rate of the femoral stems was evaluated by using the span of time to a revision operation for any reasons was defined as the end point. RESULTS: The mean HHS was 50.5 preoperatively and 84.2 at the time of last follow-up. Osteolysis only around the HA-coated proximal portion of the femoral stem was observed in 72 hips, cortical hypertrophy all around the distal portion of the femoral stem was observed in 38 hips, and calcar resorption was observed in 44 hips. A reactive line was observed in 13 hips, but was unrelated to component loosening. Stem revision operations were performed in 24 (23%) hips due to osteolysis (14 hips), fracture (5 hips) and infection (5 hips). The femoral stem survival rate was 75% over the mean duration of follow-up. CONCLUSION: Total hip arthroplasty using a HA-coated anatomical femoral stem showed necessitated a high rate of revision operations due to osteolysis around the femoral stem in this long term follow-up study.

BACKGROUND: The purpose of this study was to evaluate the clinical feasibility of an electric nerve stimulator in a lumbar transforaminal epidural block. METHODS: Using an electric nerve stimulator, transforaminal epidural blocks were performed in 105 segments of 49 patients who presented with lower back pain with radiating pain to lower extremities. The contrast medium was injected to delineate the nerve root after positioning an insulated needle at the intervertebral foramen under fluoroscopic guidance. Then, the nerve root was electrically stimulated with the insulated needle to confirm whether or not the same radiating pain was evoked. RESULTS: Of the 105 foraminal segments, the same radiating pain was evoked at 0.5 mAh in 47 segments (44.8%), at 1.0 mAh in 22 (21.0%), at 1.5 mAh in 3 (2.9%), at 2.0 mAh in 15 (14.3%), at 2.5 mAh in 4 (3.8%), and at 3.0 mAh in 5 (4.8%). No response was observed in 9 segments (8.6%). The fluoroscopy revealed successful positioning of the needle in the patients with an evoked radiating pain over 2.0 mAh. The visual analogue scale (VAS) obtained for pain improved from a mean of 7.5 to 2.7 after the block (p = 0.001). In the 9 cases without response to electrical stimulation, the patients showed an improvement on VAS from 7.8 to 3.4 (p = 0.008) also. CONCLUSIONS: A nerve stimulator can help to predict the accuracy of needle positioning as a supplemental aid for a successful lumbar transforaminal epidural block. It is sufficient to initiate a proper stimulation amplitude of the nerve at 2 mAh.

PURPOSE: We investigated if there are some differences in characteristic of recent renal infection from the past one and evaluated the need of ultrasonography in acute renal infection and the efficiency of antibiotics that have been used primarily in treatment of past renal infection. MATERIALS AND METHODS: We reviewed charts of 232 patients with acute renal infection retrospectively, who took admission treatment from 1991 to 1995 at our hospital. The laboratory tests such as complete blood count, urinalysis and urine culture with sensitivity and radiologic evaluations such as abdominal ultrasonography, excretory urography or voiding cystourethrography were performed. RESULTS: The most common age groups were 3rd decade(26.7%) and 4th decade(24.1%). Female was predominant in all age groups(M:F=1:8.7) except 1st decade(M:F=1.6:1). Acute pyelonephritis was the most common disease (87.1%) and then followed by acute focal bacterial nephritis(8.2%), renal abscess(4.3%) and perirenal abscess(0.4%). Five cases(2.2%) were accompanied by vesicoureteral reflux. Abdominal ultrasonography was done in 90.5%, but 74.8% of them were completely normal and most of abnormal findings at abdominal ultrasonography were clinically insignificant. Result of ultrasonography did not affect the outcome of the disease or the treatment plan. The significant bacterial isolation(more than 10(5)CFU/ml) in urine culture was 46.6%. Among them, E. coli was the most common organism(92.6%) and others were Enterobacter, Klebsiella or Pseudomonas. Causative agents were resistant to some drugs such as ampicillin or bactrim which have been usually used for urinary tract infection. CONCLUSIONS: Routine ultrasonography in renal infections without urinary tract obstruction was not helpful in treatment plan or outcome of this disease and selection of antibiotics in treatment of recent renal infection should be changed from the past one.
