PURPOSE: To evaluate ultrasonographic findings and usefulness in the diagnosis of breast diseases during pregnancy and lactati ng period. METHODS AND MATERIALS: The authors evaluated the ultrasonographic findings of 18 breast diseases during pregnancy and lactation retrospectively. The ultrasonographic examinations were performed with linear-array 5 MHz transducer (ATL). Final diagnoses were obtained by the excisional biopsy, fine needle aspiration and clinical follow-up. RESULTS: Total 18 cases of breast diseases were consisted of 8 cases of galactocele, 4 cases of fibroadenoma, 3 cases of axillary accessory breast, 2 cases of lactating adenoma, and I case of phylloides tumor. The ultrasonographic findings of the above breast diseases were valuable in the diagnosis and therapeutic planning. CONCLUSION: Ultrasonography is the initial and useful method of diagnosing breast diseases during pregnancy and lactating period.

Incontinentia pigmenti is an uncommon genodermatosis. It affects female infants predominantly, described first by Bardach in l925, with the diagnosis of systematized nevus and Bloch in 1926, and Sulzberger in 1928 rnore compIetely. Skin lesions are characterized by 3 stages such as vesicobullous, verucous and finally pigmentary lesions and leave brownish pigmentation on the extremities and trunk. Hesides skin lesions some ectodermaI and mesodermal organs are affected and show developmental abnormalities. We experienced a case of incontinentia pigmenti in a 45-day-old female infant and present it with the review of literature. She showed extensive vesicobullopustular eruption with linear and reticular pigmentation on the extremities and trunk. Clinical and histopathologic findings of these lesions are compatible with Bloch-Sulzberger type of incontinentia pigmenti.

We report a case of primary transitional cell carcinoma developed in bladder vdiverticulum with brief review of literatures. Patient was a 71 year-old man who had painless gross hematuria for 10 days. Excretory urogram showe a large diverticulum in the bladder. At cystoscopy a 0.5 x 0.5cm sized papillary mass was seen on diverticular mucosa. Urine cytology revealed class V transitional cell carcinoma. At pelvic CT, metastatic evidence was not seen. We carried out partial cystectomy involving diverticulum under the diagnosis of primary transitional cell carcinoma developed in vesical diverticulum. The histopathologic diagnosis was grade III, stage A transitional cell carcinoma combining with carcinoma in situ.

The lower ureter is not so frequent site of the urinary tract obstruction. In lower ureteral obstruction, the obstruction should be relieved by any method for maintaining renal parenchyme. A clinical studies were made on the 24 ureters of the lower ureteral obstruction. This studies were mainly focused on the method of management by internal stent indwelling. The following results were obtained. 1. In etiology, acquired lower ureteral strictures were most common ; tuberculosis in 10 ureters, radiation in 6 ureters, pelvic lymphadenopathy in 4 ureters, and iatrogenic stricture in 3 ureters. Congenital UVJ stricture was only one ureter. 2. In the method of management, open surgeries were done in 10 ureters and endourologic methods in 14 ureters. 3. In 5 failures of the first management, open surgeries were done in 3 ureters and endourologic methods in 2ureters. The tuberculosis was the most of their etiology. 4. Complications in internal stent indwelled cases were flank pain, severe vesical irritation, migration into the bladder and the obstruction of the lumen of stent.

Background & Objective: Sex differences in cerebral atherosclerosis and subsequent stroke have not been thoroughly investigated and conflicting data exist. The aim of this study was to investigate sex differences in the risk factors and distribution of large artery atherosclerotic stroke in a Korean population. Methods: We included consecutive acute ischemic stroke patients with symptomatic extracranial atherosclerosis (ECAS) or intracranial atherosclerosis (ICAS) based on brain and vascular imaging who presented at our hospital between January 2011 and December 2015. We then compared risk factor profiles and the proportion of symptomatic ECAS and ICAS between men and women. Results: Eight hundred and forty four patients were enrolled during the study period. The proportion of ECAS in men was notably higher than in women (19.4% in men vs. 9.3% in women; p < 0.001). A multiple regression analysis showed that male gender was a factor favoring ECAS (vs. ICAS, odds ratio [OR], 3.554; 95% confidence interval [CI], 2.175-5.808; p < 0.001). Age (OR, 1.051; 95% CI, 1.031-1.072; p = 0.001) and hyperlipidemia (OR, 2.330; 95% CI, 1.538-3.529; p < 0.001) were also factors favoring ECAS. However, after stratification by sex, the association was only significant in men. Conclusions: There is a sex difference in the distribution of atherosclerotic stroke. Sex may be an effect modifier of the association between atherosclerotic risk factors and atherosclerotic distribution.

OBJECTIVE: Asymmetries in evoked potential P300 topography of schizophrenia and bipolar disorder are still controversial. The purpose of this study was to examine the difference in P300 topography between schizophrenia and bipolar disorder. METHOD: P300 was recorded from 16 schizophrenic, 15 bipolar manic, and 16 control subjects. All were right-handed. Subjects silently counted target stimuli(2.0kHz) among trains of standard stimuli(1.0 kHz). Averages were constructed from brain responses to target stimuli. RESULTS: 1) Schizophrenics displayed significantly smaller peak amplitude of P300 over Cz, Pz, T3 than controls. 2) Schizophrenics displayed significantly smaller peak amplitude of P300 over T3 than bipolar manics. 3) Schizophrenics displayed significantly smaller peak amplitude of P300 over T3 than their T4. 4) Schizophrenics displayed significantly delayed latency of P300 over T3 than bipolar manics. 5) Schizophrenics displayed significantly delayed latency of P300 over T3 than their T4. CONCLUSION: Left-sided P300 abnormality, especially left superior temporal gyrus, in schizophrenics, relative to bipolar manics and controls suggests that psychophysiological cause of schizophrenia and bipolar disorder is different and P300 asymmetry is specific to the psychophysiological cause of schizophrenia.

Since the placenta is an organ composed of blood vessels, it is not surprising that its primary neoplasm would be a vascular tumor. Placental tumors, primary or secondary, have been known to interfere with placental function. Chorioangioma(primary tumor of the placenta), which is the most common of them, occurs with an incidence for clinically significant ranges from 1~2.8:10000 births. These tumors are benign and are not usually associated with clinical sequelae unless they are larger than 5cm in long diameter. About one third of the large chorioangiomas may be associated with the maternal and fetal complications. For diagnosis of these lesions, the ultrasonography was used. If the chorioangioma is suspected, color doppler study is informative to confirm the presence of the vascular channels. We reviewed ultrasonograms and clinical records of seven patients who had been diagnosed as placental chrioangioma. The appropriate diagnostic tests and treatment can then be initiated in order to prolong gestation and decrease fetal mortality and morbidity.

BACKGROUND: Serious pulmonary complications after lung surgery increase morbidity and mortality in perioperative period. Ketamine hydrochloride produces strong analgesic effect in spite of the psychomimetic effects. Intravenous anesthesia with ketamine was performed in lung surgery of patients with decreased pulmonary function and compared with inhalation anesthesia with enflurane. METHODS: Sixty patients, scheduled for elective lung surgery, were randomly assigned to two groups. Patients received either enflurane (Group 1, n=30) or ketamine (Group 2, n=30) as main anesthetic drug. Blood pressure and heart rate were compared in preinduction, postinduction, postintubation, postincision, intraoperative period (30 minutes, 60 minutes) and recovery room between groups, and in each group. Arterial blood gas analysis was compared in preoperative period, intraoperative period and recovery room between groups. Postoperative psychological complications evaluated in group 2. RESULTS: Blood pressure and heart rate were significantly different in postinduction, postintubation and recovery room between groups. PaO2 in group 2 was higher than in group 1 during intraoperative period and recovery room. Postoperative psychological complications occured in 4 patients (13%) in group 2. CONCLUSIONS: Ketamine affords advantage over enflurane anesthesia in terms of PaO2 during intraoperative period and recovery room in lung surgery of patients with decreased pulmonary function.

BACKGROUND: HLA-B5102 is a newly approved antigen at the meeting of the WHO Nomenclature Committee held after the Eleventh International Histocompatibility Workshop. It had been called B5l.35 because it was defined by both B5l and B35 antisera. HLA-B5102 antigen cannot be accurately determined by current commercial HLA typing trays. This study was carried out to assess the frequency of HLA-B5102 antigen in Koreans and serological reaction patterns of HLA-B5102 on commercial HLA trays. METHODS: We performed HLA-A, B, C serological typing for 2,000 Koreans registered for KMDP (Korean Marrow Donor Program) donors using the Terasaki Oriental Tray (One Lambda, USA). Selected samples (17/2000) which showed atypical B5 reaction patterns were tested against Japan Central Block HLA Workshop tray to detect the presence of HLA-B5102. RESULTS: HLA-B5102 showed a phenotype (antigen) frequency of 0.45% (9/2000) and an allele frequency of 0.23%. Two locus HLA haplotype and linkage analysis showed that HLA-B5102 was in linkage disequilibrium with HLA-A3l (p<0.01). The serological patterns of HLA-B5102 on Terasaki Oriental Tray were 1) Lot 14, 15 : B5(+), 2) Lot 15 B : B5(+), B35+53(+), and 3) Lot 16 : B5(+), B5l(+), B35+53(+), and therefore could be identified as HLA-B5, B5l, B52, B35 or B53. CONCLUSIONS: The frequency of HLA-B5102 in the Korean population (antigen frequency 0.45%, allele frequency 0.23%) is similar to that of Japanese. The presence of HLA-B5102 can be suspected when atypical BS reaction patterns are encountered in commercial HLA typing trays, and B5 or BSI had better been assigned to these cases when additional confirmatory typing is not available.
