BACKGROUND: There has been reports which suggest that non-specific symptom of patients with mitral valve prolapse is associated with autonomic dysfunction. METHODS: To assess autonomic dysfunction of patients, we examined five cardiovascular reflex tests in 25 asymptomatic MVP patients(identified as MVP group), 25 symptomatic MVP patients(identified as MVP syndrome group) and 25 control group. RESULTS: In the five cardiovascular autonomic function tests, abnormalities of Valsalva ratio were detected in 1(4%) control group, 7(28%) MVP group, 9(36%) MVP syndrome group, heart rate response to deep breathing in 0(0%), 2(8%), 4(16%) respectively, immediate heart rate response to standing in 0(0%), 2(7.4%), 2(8%) respectively and in postural hypotension, there were no abnormal group. Abnormalities of blood pressure response to sustained handgrip were only detected in 2(8%) MVP syndrom group. According to the five categories of cardiovascular autonomic functon tests, normal in 24(96%) and early damage in 1(4%) were detected in control group. In the MVP group, normal 17(68%), early damage 6(24%) and definite damage 2(8%) were noted. In the MVP syndrome group, normal 9(36%), early damage 13(52%), definite damage 1(4%) and combined damage 2(8%) were detected. In case of heart rate response to deep breathing, we found significant differences between control and MVP syndrome group(p=0.043), and between MVP and MVP syndrome group(p=0.0043). In case of heart rate response to standing, between control and MVP syndrome group(p=0.0009), between MVP and MVP syndrome group(p=0.001), the differences were noted. In case of blood pressure response to standing, between control group and MVP group(p=0.0019), between MVP and MVP syndrome group(p=0.0075), we found significant differences. Resulting from our study, heart rate response to deep breathing and standing, blood pressure response to standing were of considerable value in assessing the autonomic dysfunction of patients with mitral valve proapse. CONCLUSION: We found autonomic dysfunction in addition to increased autonomic tone and responsiveness which have been already known previously in mitral valve prolapse. And autonomic dysfunction was more severe in symptomatic patients with mitral valve prolapse than asymptomatic ones.

OBJECTIVE: The purpose of this study was to evaluate of course of delivery & perinatal outcomes for postterm pregnancy compared with fullterm pregnancy. METHODS: This study included 360 cases of postterm pregnancy out of 16,992 cases delivered at Department of Obstetrics and Gynecology from January 1, 1993 to December 31, 1997. 16,143 cases of full term deliveries of 38 to 42 gestational weeks conducted in same period were used as the control group. Postterm pregnancy was defined as a pregnancy that it exceeds 295 days calculated from first day of the last menstrual period. RESULTS: The incidence of postterm pregnancy was 2.13% with the highest incidence occurring in the 26 ~30 years age group. This study group was significantly different from the control group in the incidence of fetal distress (10.28% vs. 2.20%), large fetus (10.83% vs. 6.95%), perinatal death (1.67% vs. 0.27%). CONCLUSIONS: Adverse perinatal outcomes were increased markedly as the gestational weeks to be prolonged. Therefore, careful prenatal care, accurate determination of delivery date is very important.

Since the first report appeared in 1979, the incidence of potentially life threatening allergic reactions to latex has increased. We performed Cesarean section on a 28 yr old women who showed a severe latex allergic reaction that induced fetal distress. In the 39 th week of pregnancy, delivery was induced with oxytocin and a vaginal examination was performed using latex gloves. Chest tightness, dyspnea, urticaria, maternal hypotension (78/50 mmHg) and fetal bradycardia (40-90 beats/min) appeared suddenly 10 min after the vaginal examination. In addition to the subcutaneous injection of 0.3 mg epinephrine, diphenhydramine 45.5 mg and dexamethasone 4 mg was administered intravenously. Anesthesia was induced with thiopental and succinycholine, and maintained with isoflurane and epidural lidocaine. After operation, no additional problems were evident, except an itching sense. Potentially life threatening allergic reactions to latex should be considered in those with a high risk of latex allergy, and efforts should be made to provide this group with a latex-free environment.

An 8-year-old male was admitted because of dysphagia and substernal pain suffered while eating followed by postprandial vomiting for 2 years. He was always hungry due to postprandial vomiting and willing to eat again just after vomiting. After this meals, he used to jump up and down to shake off the substernal discomfort. A narrowing of the gastroesophageal junction was noted by esophagogram. Manometry revealed high Lower esophageal sphincter (LES) pressure (51.6mmHg), incomplete LES relaxation during swallowing, loss of esophageal peristalsis and a positive pressure of the esophageal body compared to intragastric pressure. After the 1st balloon dilatation, symptoms were much improved even though LES pressure still remained high (37.2mmHg). About 2 months after the 1st balloon dilatation, symptoms relapsed and we managed him with a 2nd balloon dilatation. Symptoms were more improved than after the 1st dilatation and LES pressure normalized as well. Since the 2nd dilatation, symptoms have not recurred for 3 years. We present an 8-year-old boy with achalasia successfully managed by the use balloon dilatation.

BACKGROUND AND OBJECTIVES: Nitric Oxide (NO) is an endogenous mediator first characterized as an endothelium-derived relaxing factor. It is now recognized as a key mediator in many physiological process such as vasodilatation, neurotransmission, host defense, and iron metabolism. However, much remains to be determined about the pathophysiological role of NO in the airway. Peroxynitrite, which is synthesized by NO, is the diret cause of cellular toxicity in inflammatory reaction. In this study, we investigated the cellular toxcity of peroxynitrite by the expression of Heat-shock proteins 70 (HSP 70) in normal human nasal epithelium (NHNE) at the inflammatory conditions MATERIALS AND METHODS: 3-Morpholinosydronimone clorhydrate which is a peroxynitrite donor was mixed in the media of cultured NHNE cell. RESULTS: HSP 70 was expressed at the peroxynitrite environment of cultured NHNE cells and HSP 70 mRNA was detected with a time-dependent increasing pattern. CONCLUSION: Peroxynitrite may have a cytotoxic effect, and inhibition of peroxynitrite synthesis may have an important role for controlling the cytotoxic and inflammatory conditions of rhinitis and sinusitis.

Dysgerminoma developed in a 21-year-old phenotypic female patient with 46,XY pure gonadal dysgenesis, Swyer syndrome. This patient presented with pelvic mass associated with abdominal pain and primay amenorrhea. Clinical characteristics showed a typical stigmata of gonadal dysgenesis: primary amenorrhea, sexual infantilism, a small uterus and left streak gonad. A 46,XY karyotype was made by lymphocyte culture. The patient was counseled to undergo operation, chemotherapy and hormon therapy. She underwent bilateral gonadectomy with total hysterectomy, partial omentectomy and multiple pelvic wall random biopsy. Histological examination revealed dysgenetic gonads with dysgerminoma. After surgery, the patient received chemotherapy and also was started on hormone replacement therapy. She is currently alive with no evidence of disease after 19 months from surgery.
