BACKGROUND: Androgenetic alopecia is a common problem, affecting approximately 50 percent of men and perhaps many women, over the age of 40 in Caucasians. There have been several reports about the prevalence and types of androgenet clopecia in the general population of Caucasians however the prevalence and types of and renetic alopecia has not been reported in the general population of Korea. OBJECTIVE: Our purpose was to ascertain the prevalence ar d ypes of androgenetic alopecia in Koreans and to compare it with that of the Caueasian. METHODS: A survey on the prevalence and clinical types of aidrogenetic alopecia was conducted by one dermatologet from July to September, 1993. The total number of subjects was 1224 males and 1094 females. RESULTS: The following esults were obtained from this sudy l. In men, the prevalence rate of androgenetic alopecia increased steadily with advancing age and the prevalence rate of more advanced degrees of alepcia(types V, VI and VII) remained relatively low until the seventh decade of life. The preralence rates until the age of sixties in Korean men were lower than that of the white and is pattern became closer with that of the white after the seventies. 2. In Korean women, the prevalence rate of androgenetic was lower than that of the white until fifties and it increased markedly after sixties. CONCLUSION: The prevalence rate of androgenetic alopecia in Korean was lower than that of the Caucasian. Our data adicates that Korean men have a late onset of baldness and more preservation of the frontal hair line with decreased frequencyte frontoparitetal loss than the Caucasian.

PURPOSE: It is important to know for transurethral resection of prostate (TURP) affecting the serum prostate specific antigen (PSA) value how long one should wait before being able to ~ obtain an accurate and meaningful serum PSA level. We evaluated the change of serum PSA concentration in patients with benign prostate hypertrophy(BPH) before and after TURP in association with time course and resected prostatic weight. MATERIALS AND METHOD: The effect of TURP was examined in 27 patients with BPH (mean age: 64 years; range: 55-79 years). The serum PSA levels were measured serially (before and 1, 3, 5, 7, 14, 30, 60, 90 days after TURP) by Abott IMX assay. RESULTS: The level of serum PSA appeared to be consistent with prostatic volume by transrectal ultrasonography(TRUS) and was elevated by about 0.16 ng/mL for each gram of hyperplastic tissue present (p=0.375, p=0.058). TURP caused an immediate elevation in the serum PSA concentration, with a median increase of 19 ng/mL (p=0.0001). The larger resected group showed a dramatic and statistically significant PSA rise immediately after TURP than the smaller resected group (p=0.023). From the 15 post-operative day, the PSA concentrations continued slightly lower than that of pre-operative day (p=0.0001), and was still decreased on 30 days (p=0.0001). The median time to return to a baseline level of PSA was 30 days (range: 1460 days) after TURP. CONCLUSION: These findings indicate that TURP caused an immediate increase in the serum PSA level, which generally return to stable, baseline level within 30 days. However, because in some patients the serum PSA still remained elevated than upper normal limit after 30 days, it is recommended that a serum PSA determination should be obtained for at least 60 days after TURP.

PURPOSE: A wide variety of surgical materials have been used for blepharoptosis such as catgut, silicone, 4-0 nylon polyfilament cable-type ophthalmic suture (Supramid(R)), autogenous tendon (palmaris longus),banked sclera, dura mater, fascia lata, and temporalis fascia. The aim of this study was to evaluate the effect of frontalis suspensory surgery with temporalis fascia. METHODS: The authors studied 91 frontalis slings (71 patients) performed from 1993 to 1999 at our hospital for repair of blepharoptosis. Results with temporalis fascia (group A) as the suspensory material were compared to those with autogenous (group B) and preserved (group C) fascia lata. RESULTS: The success rates of group A (31 lids 21 patients), group B (28 lids 24 patients), group C (32lids 26 patients) were 80.6%, 75%, 78.1% respectively. But there was no statistically significant difference in each groups (P>0.05). CONCLUSIONS: We concluded that temporalis fascia for frontalis sling could be used as suspensory material successfully. Moreover, long term and further evaluations must be considered.

Inflammatory pseudotumor of the urinary bladder is a rare benign lesion. Because it is difficult to differentiate from other tumors clinically and pathologically, histopathologic confirmation is needed, and to avoid unnecessary cystectomy, it should be included in the differential diagnosis. A 47-year-old male presented with hematuria and voiding difficulty. IVP revealed a triangular filling defect in the urinary bladder, and CT demonstrated the presence there of a strongly enhancing mass. We deseribe this case, in which inflammatory pseudotumor was diagnosed, and review the literature.

Two cats were presented with vestibular signs and seizures. Both cats were diagnosed with thiamine deficiency. The transverse and dorsal T2-weighted magnetic resonance (MR) images revealed the presence of bilateral hyperintense lesions at specific nuclei of the midbrain, cerebellum, and brainstem. After thiamine supplementation, the clinical signs gradually improved. Repeated MR images taken 3 weeks after thiamine supplementation had started showed that the lesions were nearly resolved. This case report describes the clinical and MR findings associated with thiamine deficiency in two cats.

PURPOSE: Maternal Fetal Intensive Care Unit (MFICU), which provides intensive care to high-risk mothers with increasing maternal age and high-risk newborns, has become a new field of nursing work in South Korea. The present study was conducted to identify the educational needs and self-assessing clinical competence of nurses in MFICU. METHODS: The education needs and competencies of MFICU nurses were measured through prepared questionnaires by researchers based on the previous studies on job analysis of nurses in MFICU. Data were collected from January 2019 to March 2019. The study involved 168 nurses working in MFICUs at 12 hospitals nationwide as study subjects. The data were analyzed using the SPSS WIN 23.0 program. RESULTS: The education needs of nurses in MFICU had an average of 4.21 points (±0.50) and their nursing competence was average 3.38 points (±0.60). The items reported as high education needs but low competency by nurses in MFICU were as following: ‘postpartum hemorrhage and shock,’ ‘cardiopulmonary resuscitation (CPR) for neonate,’ ‘CPR during pregnancy,’ ‘disseminated intravascular coagulation,’ ‘sepsis,’ and ‘mechanical ventilation during pregnancy.’ CONCLUSION: Based on these results, it is proposed that a comprehensive education program for nurses in MFICU should be developed by considering low capabilities among MFICU nurses as a priority factor.

This study was conducted to study the changes of cell surface carbohydrates during transdifferentiation of retinal pigment epithelial(RPE)cells. RPE cells were cultured from adult pig eyes. Surface carbohydrates of RPE cells from 1st, 3rd, 5th, 7th and 9th passages were assayed by lectin histochemistry and enzyme immunoassay. Changes in binding affinities to the lectins employed were demonsrated during trasdifferentiation of RPE cell. Whereas binding affinities of ConA, ECL, PNA, WGA, and UEA-I decreased graudally as the number of culture passage increased, binding properties to LCA, STL and DBA fluctuated depending on the number of passages. The results demonstrate changes of surface carbohydrates of RPE cell during trasdifferentiation. We suggest that changes of surface carbohydrates of RPE cell during trasdifferentiation may be close relations with the functional changes during transdifferentiation.

The aims of this study are to observe morphologic changes in normal human nasal epithelial (NHNE) cells caused by varying concentrations of histamine, to evaluate the changes in relation to the degree of epithelial differentiation, and to examine whether these changes are caused by the proper action of histamine or are general inflammatory processes represented by lipopolysaccharide (LPS). Cultured NHNE cells were treated with histamine diphosphate and LPS 0111 : B4 at different concentrations : 20 ng/ml, 200 ng/ml, 2 microgram/ml and 20 microgram/ml. The timing of the treatment was conducted in one of two ways : a duration of 48 hours on floating day 12 or a duration of seven days on floating day seven. On floating day 14, all specimens were collected, and hematoxylin & eosin staining and scanning electron microscopy (SEM) were conducted. The areas of ciliated and secretory cell were calculated with the Optimas program. In SEM of specimens that were given 48-hour treatments of histamine and LPS at 20 microgram/ml dosages, coverage by secretory cells had increased and damaged cilia were noted. In SEM of specimens given the seven-day treatment, enlargement of the secretory cell area and damaged cilia were observed after a treatment of 20 microgram/ml LPS, but in specimens treated with histamine, findings were normal. Morphologic changes caused by histamine treatment may be a nonspecific finding observed in inflammation, and the changes can vary according to the differentiation of the epithelium.
