Alteration in the hormone level associated with menstrual cycle influences the interaction between the urethra and bladder as well as detrusor function, maybe due to the common embryological origin of lower female genital and urinary tract. We tried to investigate the effect of the menstrual cycle on cystometric diagnosis through this retrospective study. 60 women with regular menstruation were enrolled in this study. The study groups were divided into 2 groups, Group I was women whose symptoms were not influenced by the menstrual cycle, Group II was women whose symptoms were adversely affected premenstrually. The majority of normal cystometric diagnosis were made in the luteal phase (Group I: 42.9% vs 4.4%, p<0.05; Group II: 50.0% vs 22.2%, p<0.05). But diagnosis of genuine stress incontinence, detrusor instability, mixed genuine stress incontinence and detrusor instability were frequently made in the follicular phase of mentruation. Normal cystometric diagnosis in the group II were more commom than the group II ( 36.8% vs 19.7%, p<0.05 ). The results of this study reveal that the timing of cystometric evaluation may influence the the detection of a positive diagnosis. In patients whose symptom are influenced by their menstrual cycle, the luteal phase may not be the correct time to make an accurate diagnosis.

The widespread uae of colposcopy in the evaluation of abnormal cervical cytology has been accompanied by a trend toward decreased utilization of Papanicolaou smears and cone biopsy. But its accuracy is dependent on the criteria determining its limitations and the observer's experience. This study was performed to evaluate the diagnostic accuracy of Papanicolaau smear and eolposcopic finding and to campare these findinga with thase af colposcopically directed biopsy, conization and hysteretomy and to determine the value of endocervical curettage. Nine hundred twenty six patients were evaluated from Jan. 1, 1986 to Dec. 31, 1993 at the cancer detectinn center of the department of obstetrics and gynecology, Yonsei University, College of Medicine. Three major classes were involved in this study ; 662 cases with within normal limit Papanicolaou amears with cervical examination grossly suspicious for cancer, 187 cases with squamous intraepithelial lesion or greater, and 72 caees with reactiue or reparative change. The patients with inveaive rnalignancies of the cervix visihle to the naked eye were not included in this study. The majority of patients(75%) were 31 to 50 years of her age. The colposcopic examination wee deemed unsatisfactory in 45 cases in whom the upper limit, of the transformation zone could not be visualized. There were 881 cases each with a satisfactory colposcopie examination. We obtained the following results. In the satisfactory group with within normal limit Pap smears which had clinical impression of gross suspicion for cancer, 54 of 662 cases(8%) were diagnosed as more than cervical intraepithelial neoplasia I and 36(5.5%) were diagnosed as more than cervical intraepithelial neoplasia II with the histology of colposcopically directed biopsy. The analysis of the diagnostic values of Pap smears for cervical cancer screening showed that the sensitivity was 80.0%, the specificity was 93.8%, the false negative rate was 80.0%, the false positive rate was 15.2%, the negative predicitive value was 92.1%, and the positive predicitive value was 83.6%. In the satisfactory group with within normal limit Pap smears which had clinical impression of gross suspicion for cancer, 54 of 662 cases(8%) were diagnosed as more than CIN I and 36(5.5%) were diagnosed as more than CIN III with the histolgy of colposcopically directed biopsy. The accuracy of colposcopic impression when compared to histology of the colposcopically directed biopsy in the satisfactory group was 89.8% (within 1histologic degree) and 82.7% (precise agreement). Histologic comparision of colposcopically directed biopsy and final surgical specimen showed accuracy of 87.2% (within 1 histologic degree) and 66.5% (precise agreement). The accuracy of endocervical curettage with colposcopically directed biopsy when compared with final surgical specimen in unsatisfactory group was 82.2% (with 1 histologic degree) and 57.7% (precise agreement). In conclusion, satisfactory colposcopic evaluation in conjuction with Pap smear offers accurate method for cervical cancer detection. But endocervical curettage with colposcopically directed biopsy appears to be of less value in unsatisfactory group. Therefore futher evaluation is need.

The authors report a xase of primary non-gestational choriocarcinoma(PNGCO) of the ovary in a prepubertal female patient and reviewed. It is an extremely rere disease of which incidence is one in 369 million. Major clinical symptom is abdominal pain, precociois puberty and it can be misdiagneosed as ectopic pergnancy. Distinction from gestational choriocarcinoma(GCO) of the ovary is important because of the worse prognosis of PNGCO. But no distinctive ultrastructural or immunohistochemical differences are found between PNGCO and GCO. Most acceptable treatment modality is an aggressive surgical therapy and systemic chemotherapy, but its progrosis is poor.

45,X/47,XYY mosaicism is a rare sex chromosomal disorder with clinical information limited to 25 cases in the literature. We report an unusual mosaic Turner syndrome case in a 35-year old Korean woman with a phenotypic female, primary amenorrhea, short stature, immature secondary sexual characteristics. Cytogenetic analysis including G- and Q-banding revealed 45,X/47,XYY mosaicism, and SRY gene was demonstrated by polymerase chain reaction(PCR). Prophylactic bilateral gonadectomy was performed because the presence of Y-chromosomal sequences in Turner stigmata may predispose this patient to gonadoblastoma formation.

The evaluation and management of the sexually assaulted women is a complex, multifaceted task. The purpose of the medical examination after a sexual assault is to assess the patient for physical injuries, and to collect evidence for forensic evaluation and possible legal proceedings. Laboratory samples should be obtained at the initial visit and should include testing for pregnancy, syphilis, and hepatitis B and human immunodeficiency virus infections. Treatment should address physical injuries, pregnancy prophylaxis, sexually transmitted diseases and psychosocial sequelae. Appropriate referral services should be initiated during the initial visit. Victims of sexual assault require appropriate care, follow-up, and information regarding their legal rights. The history should be confined to medically relevant facts and should be conducted in a safe and quiet environment. In many emergency departments, however, the emergency room doctors is responsible for the initial evaluation and management. Therefore, it is imperative that the emergency room doctors be familiar with the process and issues specific to the management of the victim of a sexual assault.

BACKGROUND: Histamine, released from mast cells in atheromatous plaque, has been known to cause cardiac ischemia or sudden cardiac death in atherosclerosis patient. Previous reports have suggested that histamine induced coronary vasoconstriction was due to increase in IP(3) and DAG, which induce release of Ca2+ from SR and increase the Ca2+ sensitivity of contractile element via activation of PKC. Recently, it was reported that application of histamine cause depolarization of intestinal smooth muscle, which may contribute to histamine-induced contraction via augmenting Ca2+ influx through activation of Ca2+ channels. However, the underyling mechanism of histamine-induced depolarization and its contribution to the magnitude of coronary vasoconstriction are still uncertain. METHOD: To elucidate the underlying mechanism of Ca2+ influx change during histamine-induced vasoconstriction, we examined the effect of Ca2+ channel antagonist and PKC blocker on histamine-induced contractions, and then measured the effect of PKC antagonist on whole cell K+ current using patch clamping method in rabbit coronary smooth muscle cells. RESULTS: Application of histamine induced phasic and tonic constraction of coronary rings via activation of H(1) receptors. Pretreatment of Ca2+ channel antagonist (nifedipine, 1 microM) or PKC blockers (10 nM staurosporine and 10 microM Go6976) markedly inhibited histamine-induced tonic contraction, which suggest that the magnitude of tonic contraction depend on the Ca2+ influx. Application of 4-AP, a blocker of voltage-dependent K+ channels, increased resting tone of coronary rings, and combined treatment of nifedipine blocked this 4-AP induced increase of resting tone. Application of active analoge of DAG (1,2-DiC(8)) significantly inhibited the activity of voltage-dependent K+ current in single smooth muscle cell, meanwhile the inactive analogue of DAG (1,3-DiC(8)) has no apparent effect on the activity of voltage-dependent K+ current. Furthermore, pretreatment of calphostin C (1 microM), a blocker of PKC, diminished the 1,2-DiC(8)-induced inhibition of K+ current. CONCLUSION: PKC dependent inhibition of voltage-dependent K+ current may be responsible for the maintaining of histamine-induced tonic contraction in rabbit coronary artery.

There has been growing interest in the use of grafts in pelvic reconstructive surgery. This article will address available graft materials and assess their clinical efficacy and safety. We conducted a Pubmed MEDLINE literature search for full-length English text studies with follow-up periods of at least one year. There are many reports on synthetic and biological graft materials; the majority are not well-designed, have short-term follow-up, small sample sizes, and poor outcome assessment. The use of non-absorbable synthetic grafts may offer excellent anatomical cure rates. However, it is associated with a high incidence of graft-related complications, including healing abnormalities and adverse bladder, bowel, and sexual function effects. These complications can be decreased with absorbable synthetic meshes, but efficacy is lower compared to non-absorbable ones. There is insufficient evidence in favor of biological grafts. In conclusion, based on current knowledge, routine application of grafts in pelvic reconstruction is not recommended. It is preferred that graft utilization be individualized, with close monitoring for complications.
