The authors examined 9 condylomas, 26 cervical intraepithelial neoplasms(CIN) and 22 invasive squamous cell carcinomas for the presence of human papillomavirus(HPV) DNA sequences by DNA-DNA in situ hybridization. In situ hybridization revealed target HPV DNA sequences mostly in the nuclei of the superficial cells from epithelium which contained either maturation or koilocytotic atypias. With the use of biotinylated HPV DNA probes 6/11, 16/18 and 31/33/35, 42 of the 57(73.7%) were positive with HPV-6/11, 23 with HPV-16/18, 32 with HPV-31/33/35 and 18 with two or more mixed probes. HPV-31/33/35 was wht most prevalent in CIN and invasive squamous cell carcinomas, follwed by HPV-16/18. The incidence of HPV DNA increased from 66.7% to 86.4% with increasing severity of the lesions from condylomas to invasive squamous cell carcinomas. Flat condyloma was most freuently accompanied by CIN.

Recurrence in patients with superficial bladder tumor is a serious problem. In one series, the recurrence rate was 73%, and invasive cancer developed in 10% of patients with recurrences. To eliminate or reduce the rate of recurrence, topical chemotherapy has been tried and showed adjunct effects. We studied to evaluate prophylactic effects of topical chemotherapy in 51 patients with superficial bladder tumor admitted to the Department of Urology, Kyung Hee University Hospital during the period from April, 1979 to April, 1984. Patients were divided into 2 groups. Group A comprised 19 patients (Adriamycin; 8, Thio-TEPA; 11) treated with topical chemotherapy following initial TUR and 27 patients treated by TUR only. Group B comprised 5 patients treated with topical chemotherapy (Adriamycin) after repeated TUR and 7 patients among 27 patients who had repeated TUR for recurrence. Patients treated by TUR only were defined as control group. Recurrence rate was analyzed in each group. Following results were obtained. 1. In group A, recurrence rate was 2.54 in patients with chemotherapy comparing to 3.35 in control patients. Average interval of recurrence was 39.3 months in chemotherapy patients and 29.8 months in control patients. 2. In group B, recurrence rate was higher in chemotherapy patients than in control patients with rate of 6.6 and 5.3, respectively. But recurrence rate was diminished to 6.6 after chemotherapy comparing to pre-chemotherapy period (10.3). 3. There was no difference in recurrence rate relating to multiplicity of tumor as a whole.

Amputation of penis occurs most commonly as an act of self-emasculation. Fortunately, complete amputation of penis is quite rare but potentially devastating occurrence. Reimplantation of the penis has both cosmetic and functional objectives. Recently, several successful applications of microvascular technique to reimplantation of the amputated penis have been reported. Also herein, we present a case of successful reimplantation of completely amputated penis by using a microvascular repair.

The objective of this study was conducted to investigate growth and development status of infants fed soy-based formulas over 3 months. The height and weight were measured and Z-scores were calculated by using standard of the same age groups. Their mothers were interviewed using questionnaires including general and environmental characteristics, total food intakes, soy based formula intakes and Ewha infant development screening test. Main results were as follows: 1) Nutrient intake levels of subjects were similar to or more than the level of Korean Recommended Dietary Allowances except for intakes of vitamin E (79.89% RDA), and the average status of nutrient intakes of infants were fairly good. 2) Z-scores of height for age (HAZ) and Z-scores of weight for age (WAZ), Kaup index, WLI and Ewha Infant Developmental Screening Test score of subjects were in the normal growth range. 3) There were no significant differences among soy based formula intake percentile groups in HAZ, WAZ, Kaup index, WLI and Ewha Infant Developmental Screening Test score. 4) Total energy intake was positively correlated with HAZ (p < 0.01), WAZ (p < 0.01), and WLI (p < 0.05) in infants less than 12 month. Also, soy based formula energy intake was positively correlated with HAZ (p < 0.05) in infants less than 12 month. However, energy and soy based formula intake levels of infants over 12 month were not significant among variables. Considering results of this study, infants fed soy-based formulas over 3 months showed normal growth and development status. Further studies are needed to evaluate long-term growth and development in infants fed soy based formulas.

PURPOSE: To report a case of acute endophthalmitis associated with 23-gauge transconjunctival sutureless vitrectomy and gas tamponade for macular hole surgery. CASE SUMMARY: A 66-year-old female patient who presented with a macular hole in the left eye was treated with 23-gauge transconjunctival sutureless vitrectomy. On postoperative day 2, the patient developed acute endophthalmitis and was treated with gas-fluid exchange, lensectomy and intravitreal antibiotic injection. Staphylococcus epidermidis was detected in the vitreous fluid of the operated eye. Intraoperative fundus findings showed severe retinal hemorrhage, vascular occlusion and fibrous membranes due to inflammatory response. After treatment, the patient's fundus findings markedly improved and the inflammatory response was controlled. CONCLUSIONS: Acute endophthalmitis after sutureless vitrectomy performed via intraocular gas injection may quickly result in inflammation and disease due to infection. Immediate reoperation and intravitreal antibiotic injections are recommended in such cases.

PURPOSE: To determine useful diagnostic criteria of cubital tunnel syndrome (CTS), using ultrasonographic ulnar nerve cross-sectional areas (UNCSA) measurements. MATERIALS AND METHODS: The CTS group included 28 patients confirmed with nerve conduction study and the control group included 17 healthy adults. Ulnar nerve cross-sectional areas (UNCSA) were measured at the distal 1/3 upper arm level and in the cubital tunnel (CTN). US findings of CTS were ulnar nerve dislocation (n = 2), ulnar nerve subluxation (n = 5), ganglion (n = 1), sever elbow joint osteoarthritis (n = 1) and elbow joint valgus deformity after fracture (n = 1). UNCSA, the ratio of UNCSA in CTN to distal 1/3 upper arm level (CH ratio), and the difference of UNCSA between CTN and distal 1/3 upper arm level (CH difference) were evaluated to obtain the optimal diagnostic cutoff value of CTS, using ROC curve. RESULTS: The mean UNCSA in CTN was 0.168 cm2 in the CTS and 0.067 cm2 in the control. The CTS could be diagnosed when UNCSA, the CH ratio and the CH difference are larger than 0.096 cm2, 1.371 and 0.036 cm2 respectively. The ROC curve area was largest and the sensitivity, specificity was respectively 82.4%, 95.8%, when the CH difference was used as cutoff value. CONCLUSIONS: Ultrasound is useful for the detection of CTS pathogenic lesions in CTN. The highest diagnostic accuracy was acquired when the CH difference is larger than 0.036 cm2.

PURPOSE: It is not common to evaluate the response of the fractionated stereotactic radiotherapy (SRT) to primary hepatoma as compared with conventional radiotherapy. The purpose of the study was to take the preliminary result on the clinical trial of primary hepatoma by SRT. MATERIALS AND METHODS: From July 1999 to March 2000, thirty three patients were hospitalized in the St. Mary's Hospital, and treated with SRT for extracranial tumors. Among them, 13 patients were diagnosed to primary hepatoma and then applied by frameless SRT using 6 MV linac accelerator. There were 12 male and 1 female patients. They had the age of 44~66 year old (median : 59) and the tumor size of 10~825 cc (median : 185 cc). SRT was given to them 3~5 fractions a week (5 Gy/fraction, 90% isodose line) for 2~3 weeks. Median dose of SRT was 50 Gy and the range was 30~50 Gy. RESULTS: Follow-up period ranged from 3 months to 13 months with median of 8 months. After treating SRT to thirteen patients with primary hepatoma, the response of the tumor was examined by abdominal CT : they are classified by 1 complete regression (7.7%), 7 partial regression (53.8%), 4 minimal regression (30.8%), 1 stable disease (7.7%). The positive responses more than partial remission were 8 patients (61.5%) after the treatment. The level of serum alpha-fetoprotein (AFP) after the treatment as compared with pretreatment had been 92.3% decreased. There was no severe complication except dyspepsia 84.6%, mild nausea 69.2%, transient decreased of hepatic function 15.4% and fever 7.7%. CONCLUSION: SRT to the patients with primary hepatoma was potentially suggested to become the safe and more effective tool than the conventional radiotherapy even though there were relatively short duration of follow-up and small numbers to be tested.

BACKGROUND: Postoperative residual curarization subsequent to the use of neuromuscular blocking drugs can cause respiratory problems. This study examined the incidence of postoperative residual curarization on the arrival of patients in the recovery room. METHODS: Two-hundred-fifty-nine patients were enrolled in the study. The neuromuscular blockade was maintained with vecuronium or rocuronium and all subjects were reversed with pyridostigmine. The train of four ratios (TR) was quantified by acceleromyography immediately upon their arrival in the recovery room. The residual curarization was defined as a TR of < 0.9. RESULTS: The incidence of residual curarization was 32.8% (84 patients). The time from the last dose of muscle relaxants to the TR assessment in the recovery room was significantly different between those with a TR <0.9 (74.9 +/- 35.3 min) and a TR > 0.9 (104.5 +/- 51.1 min) patients. The total dose of muscle relaxants corrected by the ED95 was significantly different between TR < 0.9 and TR > or = 0.9 patients. The total dose of vecuronium or rocuronium, and the dose of pyridostimine was similar in the TR < 0.9 and TR > or = 0.9 patients. CONCLUSIONS: Significant postoperative residual curarization waspresent in the majority of patients, even with the use of intermediate- acting neuromuscular blocking drugs. In addition, the time from the last dose of muscle relaxants to the TR assessment in the recovery room is a major factor that affects the residual curarization.

BACKGROUND: Hip replacement arthroplasty (HRA) is highly traumatic and performed in a lateral position for several hours and dead-space ventilation may increase. So, the difference between arterial and end-tidal PCO2 was investigated depending on the changes in the patient's posture during HRA in elderly patients. METHODS: Forty-three patients scheduled for a HRA were divided into two groups; Adult Group (n = 21, A-Group) and Elderly Group (n = 22, E-Group). Mean arterial pressure (MAP), heart rate (HR), PaO2, PaCO2, and end-tidal carbon dioxide tension (P(ET)CO2) were simultaneously measured at 10 min after anesthesia in a supine position (S[10]), at 30 min intervals from 30 min (L[30]) to 180 min (L[180]) in a lateral position and at 10 min in a supine position after the end of surgery (ES[10]) in both groups. The PaCO2-P(ET)CO2 gradient (P[a-ET]CO2) and dead space ventilation (Vd/ Vt) were calculated. RESULTS: At S(10), P(a-ET)CO2 in the A- and E-Groups was 7.0 +/- 5.0 and 7.2 +/- 3.3 mmHg respectively. From L(30) to ES(10), the P(a-ET)CO2 and the ratio of Vd/Vt in both groups increased significantly and progressively (P < 0.05 vs the control value) and the slope in the E-Group rose two times as compared to that in the A-Group. The correlation coefficient between P(a)CO2 and P(ET)CO2 was very significant from S(10) to L(90) and ES(10) in the A-Group, and from S(10) to L (60) in the E-Group (P < 0.01). CONCLUSIONS: For maintaining adequate ventilation of the elderly patient during HRA, PaCO2 should be measured intermittently along with the position changes after anesthesia in addition to the constant monitoring of PETCO2.

BACKGROUND AND OBJECTIVES: When noise-induced hearing loss occurs, destruction of the hair cells is accompanied by mechanical injury, chemical injury, and hypoxia. Proteomics is a powerful tool for protein analysis, as it provides valuable information regarding the biochemical processes involved in diseases, monitors cellular processes, and characterizes protein expression levels. We attempted to identify the proteins associated with the pathophysiology of noise-induced hearing loss, as well as the mechanisms of this disease, using a proteomics approach. MATERIALS AND METHODS: We used BALB/C male mice. The control mice were placed in a booth without noise, while the experimental mice were exposed to noise for three hours daily for three consecutive days. Cochleae from each group were obtained for total protein extraction. The proteins were separated into numerous spots using two-dimensional electrophoresis. Seven protein spots that were strongly detected only in the noise-exposed cochleae were selected and subsequently analyzed using matrix-assisted laser desorption/ionization time of flight mass spectrometry. RESULTS: Approximately 286 protein spots were detected in the noise group. Seven selected spots were analyzed and various proteins identified, including tyrosine protein kinase MEG2, angiopoietin-like 1, heat shock 70 kDa protein, sodium dicarboxylate cotransporter 1, myeloid Elf-1-like factor, disintegrin, metalloproteinase domain 7, and activated leukocyte-cell adhesion molecule. CONCLUSIONS: We identified several proteins expressed in noise-induced hearing loss using a proteomics approach. These proteins may help us to understand the pathogenic mechanisms of noise-induced hearing loss.
