OBJECTIVE: To understand the difference of defecation physiology between postpartum and postoperative women. METHODS: Between July 1998 to April 1999, we performed defecogram and pudendal nerve motor latency to 31 women, who were 8 postoperative women, 9 post cesarean-section state women, and 14 normal vaginal delivery-state women. RESULTS: According to the defecogram results, only squeezing angles of the anorectal angle were significantly increased(96.0 vs 72.3, 74.9 degree) in normal vaginal delivery-state women compared to post cesarean-section state and postoperative women, but rest and evacuation angles were not. And to pudendal nerve latency, there were no statistically significant difference. CONCLUSION: We concluded that the pudendal plexus was damaged during labor, therefore its ability to control puborectalis muscle was damaged. So, the anorectal angles of squeezing of postpartum women were significantly increased, compared to those of post cesarean section women or postoperative women.

PURPOSE: Thyroid transcription factor-1 (TTF-1) has been known to regulate the transcriptional activity of thyroid-specific genes. Ki-67 has been known as a marker for indicating tumor growth. This study was designed to campare the expressions of TTF-1 and Ki-67 on non- neoplastic and neoplastic thyroid tissues. METHODS: The surgically resected specimens of various histological types of thyroid tumor, from the files of the Dept. of surgery, Chung-Ang University Pil-Dong Hospital, between January 1998 and June 2002 were reviewed, and 55 cases selected for immunohistochemical studies. The materials consisted of tissues from 10 nodular hyperplasias, 28 papillary carcinomas, 15 follicular adenomas and 12 follicular carcinomas. All specimens were routinely processed, and paraffin blocks were available in all cases. Immunohistochemical stains for TTF-1 and Ki-67 were also performed. RESULTS: In all the cases, including the nodular hyperplasias, papillary carcinomas, follicular adenomas and follicular carcinomas, expressions of the TTF-1 were observed. The properties of the TTF-1 expression, including staining intensity, extent and index were not related to the tumor type. The expression of TTF-1 was inversely correlated with the tumor proliferation fraction, as assessed by the Ki-67 staining index. CONCLUSION: TTF-1 was expressed in almost all the benign lesions and well differentiated carcinomas, and correlated with the tumor proliferation fraction.

PURPOSE: Skin allergies through type 1 and 4 hypersensitivity reactions are the most frequent manifestations of drug allergies. We had previously experienced a case of a nurse with cefotiam-induced contact urticaria syndrome. To aid in preventing the progression of drug-induced allergic disease in nurses, we conducted a survey of tertiary hospital nurses who were likely to have been exposed professionally to antibiotics. METHODS: All 539 staff nurses at a tertiary hospital were asked to respond to a questionnaire regarding antibiotic exposure. Of the 457 nurses (84.8%) who responded, 427 (79.2%) received a physical examination of the hands and 318 (59.0%) received skin prick tests with the beta-lactam antibiotics cefotiam, cefoperazone, ceftizoxime, flomoxef, piperacillin and penicillin G. RESULTS: A positive response to at least one of the antibiotics occurred in 8 (2.6%) of the 311 subjects included in the analysis and stages 1 and 2 contact urticaria syndrome were observed in 38 (8.9%) and 3 (0.7%) of 427 nurses, respectively. The frequencies of a positive antibiotic skin test (6.9 versus 1.3%, chi-square=7.15, P=0.018), stage 1 contact urticaria syndrome (14.4 versus 7.4%, chi-square=4.33, P=0.038) and drug allergy (15.3 versus 3.6%, chi-square=18.28, P=0.000) were higher in subjects with a positive skin allergy history than in those without. Allergic rhinitis (P=0.02, OR=3.86, CI=1.23-12.06), night cough (P=0.04, OR=3.12, CI=1.03-9.41) and food allergy (P=0.00, OR=9.90, CI=3.38-29.98) were significant risk factors for drug allergy. CONCLUSIONS: Antibiotic sensitization and drug allergy occurred more frequently in nurses with a positive skin allergy history. Atopy may be an important risk factor for drug allergy.

Purpose: Although osimertinib is the standard-of-care treatment of epidermal growth factor receptor (EGFR) T790M mutation–positive non–small cell lung cancer, real-world evidence on the efficacy of osimertinib is not enough to reflect the complexity of the entire course of treatment. Herein, we report on the use of osimertinib in patients with EGFR T790M mutation–positive non–small cell lung cancer who had previously received EGFR tyrosine kinase inhibitor (TKI) treatment in Korea. Materials and Methods: Patients with confirmed EGFR T790M after disease progression of prior EGFR-TKI were enrolled and administered osimertinib 80 mg daily. The primary effectiveness outcome was progression-free survival, with time-to-treatment discontinuation, treatment and adverse effects leading to treatment discontinuation, and overall survival being the secondary endpoints. Results: A total of 558 individuals were enrolled, and 55.2% had investigator-assessed responses. The median progression-free survival was 14.2 months (95% confidence interval [CI], 13.0 to 16.4), and the median time-to-treatment discontinuation was 15.0 months (95% CI, 14.1 to 15.9). The median overall survival was 36.7 months (95% CI, 30.9 to not reached). The benefit with osimertinib was consistent regardless of the age, sex, smoking history, and primary EGFR mutation subtype. However, hepatic metastases at the time of diagnosis, the presence of plasma EGFR T790M, and the shorter duration of prior EGFR-TKI treatment were poor predictors of osimertinib treatment. Ten patients (1.8%), including three with pneumonitis, had to discontinue osimertinib due to severe adverse effects. Conclusion Osimertinib demonstrated its clinical effectiveness and survival benefit for EGFR T790M mutation–positive in Korean patients with no new safety signals.
