OBJECTIVES: To study the distributions of pH and gas values in umbilical arterial(UA) blood of normal newborns following uncomplicated pregnancies and vaginal births. Methods: In 457 consecutive normal term infants who were born between March 1995 and June 1998, we examined the UA pH and blood gas values obtained immediately following delivery. Maternal inclusion criteria were defined as an uncomplicated singleton pregnancy and a normal full term spontaneous vaginal delivery. And also neonatal inclusion criteria were defined as a normal intrauterine growth appropriate for gestational age without any malformations and Apgar score of 7 or more at both one and five minutes after birth. Umbilical artery blood samples were collected at each birth and were evaluated for pH, carbon dioxide pressure (PaCO2), oxygen pressure (PaO2) and actual bicarbonate. RESULTS: Histogram of UA pH value resemble normal distribution curve. The lowest UA pH was 7.04 and the 10th percentile value was 7.23. The median UA pH was 7.31 and 5% was below 7.20. The lowest UA PaO2 was 4.6mmHg and the 10th percentile value was 11.5mmHg. The highest UA PaCO2 was 67.2mmHg and the 90th percentile value was 56.5mmHg. The lowest bicarbonate value was 13.2mmol/L and the 10th percentile value was 18.4mmol/L. CONCLUSION: The distributions of the UA pH and gas values of the collective of normal newborns were illustrated. None of the UA pH was below 7.0.

PURPOSE: We reviewed 5 years worth of experience with peritoneal drainage and dialysis in infants who underwent open heart surgery. The aim of this study was to investigate the effect of peritoneal drainage and peritoneal dialysis on fluid balance and several parameters of intensive care. METHODS: Six(10%) of 60 consecutive infants who underwent open heart surgery required peritoneal dialysis during peritoneal drainage. Simple peritoneal drainage was performed in the remaining 54 infants. The silicone rubber peritoneal dialysis catheter was inserted into the center of abdominal cavity just after operation, and subsequent peritoneal drainage was maintained during intensive care. RESULTS: Mean age of the study group was 0.48+/-0.21 years(M: F=32: 28). Early postoperative mortality amang the infants with congenital heart disease was 1.6%. Total amount of output was 7.0+/-2.28mL/kg/hr, urine output 5.14+/-2.9lmL/kg/hr, pleural fluid 0.80+/-0.5lmL/kg/hr, and peritoneal fluid 1.20+/-0.90mL/kg/hr. The ratio of output to intake(O/I) was 1.06. None of the complications required early termination of peritoneal drainage or peritoneal dialysis. Hemodynamics and pulmonary function were maintained steadily during postoperative intensive care. CONCLUSION: The early institution of peritoneal drainage and peritoneal dialysis in infants with congenital heart disease after cardiac operations not only removes fluid, thus easing fluid restriction, but may also improve cardiopulmonary function.

In the review of a series of 71 clavicle shaft fracture that were treated with open reduction and internal fixation, we tried a direct comparison between two fixation modes, that is, the fixation with plate and screws (54 cases) and the intramedullary nailing with Knowles pin (17 cases). The average time to healing was not significantly different between the two group; 10.8 weeks after the plating and 11.7 weeks with Knowles pinning. The rate of successful healing within four months after the surgery were also high in both groups: one delayed union and one nonunion in the plate group, and one delayed union in the Knowles pin group. There was one loosening in the Knowles pin group, which needed reoperation. Intramedullary fixation has several advantages compared with fixation with a plate and screws. It can be performed through a shorter incision: less dissection of soft tissue is needed: and, after healing, the pin is easily removed through a small incision under local anesthesia.

OBJECTIVE: The ovarian cycle is characterized by repeating patterns of cellular proliferation and differentiation that accompany follicular development and the formation and regression of the corpus luteum (CL). That angiogenesis may play an important role in this process. Angiogenesis is supposed to be regulated by vascular endothelial growth factor (VEGF). The goal of the present investigation, therefore, was to determine whether the expression of VEGF was changed in the normally cycling human ovary. We also investigated VEGF expression in the regressed CL (ie, nonfunctiong CL) of normal term pregnancy to define the association with steroidogenic activity. To our knowledge there is no report available on VEGF expression in the CL of term pregnancy. METHODS: We assessed VEGF expression in ovaries obtained from, 26-42 yr of age, and from patients undergoing hysterectomy and salpingo-oophorectomy for nonendocrinological or nonovarian disorders. Tissue samples from premenopausal women included specimens from follicular (n=4) and luteal (n 4) phases. In addition, we studied ovarian specimens from pregnant women (n=3). Immunohistochemical analysis for VEGF was performed using a rabbit polyclonal antibody directed against human VEGF. RESULTS: These data demonstrate a development-related VEGF expression in the follicle and indirectly show that VEGF expression may be up to the existence of LH-receptor. And also, VEGF was overexpressed in the regressed CL of pregnant women compared with the functioning CL of nonpregnant cycles CONCLUSION: This study suggests that the intensity of VEGF expression is not correlated with steroidogenic activity, although both of them are stimulated by LH.

Objectives: ：Sexual dysfunction is common in both untreated and treated patients with schizophrenia and known as affecting the quality of life and drug compliance. The primary objective of this study is to estimate the prevalence of sexual dysfunction in Korean patients with schizophrenia treated with antipsychotic medications compared with healthy controls. Methods: ：Subjects were 75 patients who were recruited from outpatients with a diagnosis of schizophrenia or schizoaffective disorder according to DSM-IV-TR criteria, who had been stabilized on antipsychotic medications for more than three consecutive months. Control group consisted of 76 volunteers without history of any psychiatric disorder were excluded. We assessed for sexual dysfunction by the ASEX. Results: ：The prevalence of sexual dysfunction in the patient group was 57.33%, while that of the control group was 23.37%. Female gender and the use of antidepressants were best predictors of sexual dysfunction in patient group. Sexual difference at sexual drive observed in the control group diminished in the patient group. Conclusion ：The present study demonstrated a higher prevalence of sexual dysfunction in patient group than control. Clinicians should consider the differential sexual dysfunction effects of antipsychotics when prescribing medications.

Congenital middle ear cholesteatoma is a keratinizing squamous epithelial cyst that classically presents as a white "pearl" in either the anterosuperior or posterosuperior quadrants behind an intact tympanic membrane. The presenting features of congenital cholesteatoma depend upon the initial site of the disease. The most common presentation of this disease is a conductive hearing loss or a facial palsy of gradual onset. Other presentations include incapacitating vertigo with nystagmus, a feeling of fullness in the ear, frequent otalgia, an abnormal eardrum noted at physical examination for an unrelated condition and meningitis. Recently, we experienced a case of congenital cholesteatoma that was presented as a post-auricular fistula. In considering the management of such a fistula, it would be important to recognize the possibility that the disease may present in this way.

BACKGROUND: There are many documents about the hemodynamic changes during sympathetic blockade produced by epidural anesthesia, but few reports have addressed the effects of epidural anesthesia on renal blood flow and function. We evaluated the effects of epidural anesthesia on renal function in patients undergoing total abdominal hysterectomy with general anesthesia. METHODS: Thirty patients were randomized to groups I (n = 15) or II (n = 15). The epidural catheter was inserted via 17 gauge Tuohy needle through the L2-L3 intervertebral space of the patients in both groups, only in group II, the patients received 15 ml of 0.125% bupivacaine. All the patients were anesthetized with enflurane, nitrous oxide and oxygen. We measured mean arterial pressure and urine output, creatinine clearence, Na clearence, fractional excretion of Na and free water clearance during operation and compared the data between the two groups. RESULTS: Mean arterial pressure was lower in group II than in group I (P < 0.05), but other data were not different significantly between the two groups. CONCLUSIONS: Renal function was maintained even though epidural anesthesia reduced mean arterial pressure.

PURPOSE: The onlay island flap and tubularized incised plate (TIP) urethroplasty commonly preserve the urethral plate during each procedure, but there is a dearth of comparative data. Thus, we retrospectively reviewed our clinical data to compare the surgical outcome of the onlay and TIP urethroplasty for hypospadias correction. MATERIALS AND METHODS: We performed onlay urethroplasty in 23 patients and TIP urethroplasty in 28 patients between 1995 and 2002. The age at the time of surgery, operation time, postoperative complications, and the duration for the development of complications in each procedure were compared. RESULTS: Among the 28 cases of TIP urethroplasty, 21 were primary, 6 were secondary, and the last case was a tertiary repair, while all of the 23 cases of onlay urethroplasty were primary (age range: 8 month to 11 year). The most common complication in both procedures was urethrocutaneous fistula. Residual curvature was more common in the onlay urethroplasty group. Delayed complications, which developed later than 6 months after surgery, were 30% in both groups. The success rate was similar between the two groups, but the TIP urethroplasty group illustrated a significantly shorter operation time than the onlay group. CONCLUSIONS: The most common complication was fistula in both the onlay and TIP urethroplasty groups. Even though the success rate was similar in both groups, the operation time of the TIP urethroplasty group was shorter than that of the onlay group. Also, the TIP urethroplasty procedure resulted in more acceptable cosmetic results including a slit like neourethral meatus.
