1.The Efficacy of Vaginal Fluid B-hGC Levels for Detecting Premature Rupture of Membranes.
Korean Journal of Perinatology 1998;9(4):415-420
Premature rupture of membranes(PROM) means the rupture of amniotic membranes at any time prior to labor during the gestational period. The dilemma of correctly diagnosing rupture of the fetal membranes is well known as the consequences of management based on an incorrect diagnosis. This study was undertaken to determine if the measurement of B-hCG levels in the vaginal fluid is useful for the diagnosis of premature rupture of membranes. HCG is synthesized and secreted by the placental syncytiotrophoblast and it is normally found in amniotic fluid, maternal urine and blood. We used B-hCG for diagnosis of PROM to exclude the cross reaction with other hormones. After irrigating the posterior vaginal fornix with 3 ml of sterile saline and obtaining vaginal washings, we measured B-hCG levels. The groups were classified normal group(group I), confirmed PROM group(group II ), and suspicious PROM group(groupIII) during the third trimester. The median and 95% confidence intervals(CIS) of vaginal fluid B-hCG in each group(normal, confirmed PROM, suspicious PROM group) were 30.99mIU/ml(range: 0.32-209.89mIU/ml), 188.61mIU/ml(range: 9.65-2095.00mIU/ml), 69.63mIU/ml(range 4.76-349.56mIU/ml). There was significant difference between normal and confirmed PROM group(p<0.05), sensitivity was 95.00%, specificity 80.00%, positive predictive value 82.60%, negative predictive value 94.12%, and accuracy 87.50%, using threshold value of 60mIU/ml. There was significant difference between normal and suspicious PROM group(p<0.05) but the result of the B-hCG was not used in the obstetric decision. In terms of these results, the B-hCG level in vaginal fluid is a useful marker of PROM during the third trimester. A new technic is proposed to confirm the diagnosis of rupture of the membranes based on the introduction of B-hCG in vaginal fluid.

OBJECTIVES: Chronic pain is one of the most common experiences of humans and a typical psychophysiological disorder. The aim of this study was to measure the psychophysiological responses in chronic pain patients using a biofeedback system, and to compare them with the results from normal healthy subjects. METHODS: Forty two patients with chronic pain (17 males and 25 females, average age 44.67+/-11.10 years) and 42 normal healthy controls (17 males and 25 females, average age 45.17+/-10.46 years) participated in this study. Electromyography (EMG), skin conductance (SC), and skin temperature (ST) were recorded using biofeedback system during the 3 phases (baseline, stress, and recovery) of stress reactivity test, and average values of them were calculated. Difference of values between two groups in each corresponding phase was analyzed with independent t-test, and change of values across phases of stress reactivity test was analyzed with paired t-test (all two-tailed, p<0.05). RESULTS: Compared to normal controls, chronic pain patients had higher value of EMG (baseline : 8.10+/-5.97 micronV vs 4.72+/-1.52 micronV, t=-3.56, p<0.01 ; stress : 11.25+/-6.89 micronV vs 8.49+/-4.78 micronV, t=-2.13, p<0.05 ; recovery : 7.12+/-3.77 micronV vs 4.78+/-1.59 micronV, t= -3.70, p<0.01) and SC (baseline : 1.06+/-1.0 micronS vs 0.42+/-0.29 micronS, t=-4.0. p<0.01 ; stress : 1.87+/-2.05 micronS vs 1.03+/-0.86 micronS, t=-2.47, p<0.05 ; recovery : 1.74+/-1.77 micronS vs 0.64+/-0.59 micronS, t=-3.8, p<0.01) in all the 3 phases. But, skin temperature comparison did not reveal significant differences in all the 3 phases between two groups. CONCLUSION: Psychophysiological responses of chronic pain patients in stress reactivity test were different from those of normal healthy controls. These results suggest that sympathetic nervous system is more activated in chronic pain patients.

A clinical and histopathological study was performed on ninety-four patients with nephrotic syndrome (91 idiopathic and 3 secondary) who were admitted to Department of Internal Medicine, Yeungnam University Hospital during the period of nine years, from January 1985 to May 1994. The results were as following. 1. the ratio of male to female was 1.76:1. In young age group, minimal change was the most predominant type. In old age group, membranous glomerulonephritis and focal glomerulosclerosis were predominant types. 2.- The primary nephrotic syndromes were 96.8% and secondary nephrotic syndromes were 3.2%. Histopathologic findings of 94 renal biopsy tissue were classified into minimal change (43.6%) mesangial proliferative glomerulonephritis (29.8%), membranous glomerulonephritis (12.8%), Typel membranous proliferative glomerulonephritis (4.3%), focal glomerulosclerosis (3.2%) .and others (6.4%). 3. The response of eighty-six patients treated with steroid showed complete remission in 51.2%, partial remission in 20.9%, steroid dependent in 2.3%, and no effect in 25.6% of cases respectively. The response to steroid therapy was most effective in the patients with minimal change lesion. 4. In the patient with membranous proliferative glomerulonephlitis, long-term angiotensin converting enzyme inhibitor treatment showed less deterioration of renal function.

This is a case of synovial chondromatosis involving the left knee joint of a forty one year old man. Chief complaints were gradual development of pain and limitation of knee joint motion of about 10 years duration. K-ray study revealed a single radio-opaque loose body filling the joint cavity. This body, measuring about 3×2×2cm, was removed surgically and found to have a pedicle from the synovial membrane, consisting of fat and fibrous tissue. The diagnosis of synovial chondromatosis was confirmed by pathological study. The postoperative course was uneventful and three months after the operation, the range of motion of the affected knee joint was good.

Traumatic dislocation of the peroneal tendon is an infrequent injury. This injury is caused by forceful dorsiflexion of the foot accompanied by a powerful contraction of the peroneal muscles. This mechanism of injury tears the superior peroneal retinaculum and allows the tendons to snap anteriorly. We experienced a case of chronic recurrent dislocation of the peroneal tendon, which was treated by bone block surgery using autograft of lateral fibula and reattachment of the superior peroneal retinaculum. The clinical result was satisfactory.

BACKGROUND: Polyethylene glycol(PEG) has been the most widely used colonic lavage solution. But large volume and salty taste of PEG solution is a problem which can lead to the noncompliance and the poor bowel cleansing. Recent reports have suggested that sodium phosphate solution of much smaller volume is more effective in colon cleansing ability and more easier to complete. Therefore, this study was designed to compare two solutions for colonoscopy and to determine the differences in either patient compliance or cleansing ability. METHOD: Eighty-two patients were randomized to take either oral sodium phosphate solution or 2 liter of PEG solution. Patient's discomfort and tolerance during ingestion was asessed by questionnaire and one colonoscopist who did not know the type of solution, assessed colonic preparation status. RESULTS: Among 25 patients experiencing two separate colonoscopies with PEG solution and sodium phosphate solution respectively, 19(76%) patients preferred sodium phosphate solution. Sodium phosphate solution was found to be easier to take. Sodium phosphate caused thirst more frequently(p=0.013) than PEG solution. Particulate stool and water retention status were similar in two groups. Gas bubble formation that disturbs luminal observation was more frequently found in sodium phosphate preparation group(P=0.00). Sodium phosphate was more effective in right colon cleansing ability than PEG preparation(P=0.04). The Colonoscopist assessed sodium phosphate as "good" in 47.2% vs 58.6% after PEG preparation as a whole, but there was no statistical difference. CONSLUSION: Sodium Phosphate solution is better tolerated and more easier to take than PEG solution. Gas bubble formation is a correctable problem, but right colonic cleansing effect is not. Our results showed that sodium phosphate is likely to be more effective in colonic cleansing effect comparing to polyethylene glycol solution.

The authors performed a retrospective review to find out optimal treatment plan in infantile fistula-in-ano. There were seventy-one patients in a 2-year period. All were male and other clinical characteristics were similar to previous reports. The onset in 60 patients(97%) of the cases was in the first 1 year of alee, especially in the first 3 months(52%). We investigated patterns of disease progression in multiple-lesion cases(19cases 29%). In 5 out of 9 cases of which we could identify the patterns, new lesion developed from 1 month to 4 months after index lesion. Fifty Patients underwent fistulotomy under principle of early surgical intervention, No recurrence was found except 2cases who needed second operation during 30 months of median follow-up(23~48 months). In 21 patients whose parents did not want operation, we performed simple drainage and followed-up. Six out of 12 patients who could be communicable had no fistula-related symptoms from 20 months to 31 months. This suggests that simple drainage has therapeutic effect in some portion of infantile abscess. We conclude that simple drainage should be initial treatment of choice in infantile perianal abscess. We suggest that definite operation for recurrent abscess and fistula with relatively mild symptoms should be delayed until 1-year of age because of interval ccurrence of multiple lesions and therapeutic effect of simple drainage.

Immunological effect of the extract (KM-110) from Korean mistletoe (Viscum album coloratum) was examined. Lymphocytes obtained from KM-110-administrated mice showed increased responsiveness to mitogens, concanavalin-A (Con.A) and lipopolysaccharide (LPS). In order to study cytokine induct ability of the KM-110, macrophages from the Balb/c mice were cultivated in the medium containing the extract. the macrophages were shown to induce secretion of tumor necrosis factor-alpha (TNF-alpha), interleukin 1 and 6 (IL-1, IL-6) and interferon-gamma (INF-gamma). We then tested antitumor activity of the macrophages activated by the KM-110. Peritoneal macrophages harvested from the KM110-treated Balb/c mice exhibited cytotoxicity against the syngeneic 3LL carcinoma cells. ...continue...

OBJECTIVE: Many evidences raise the possibility that the panic disorder (PD) patients with respiratory subtype (RS) may have characteristic structural abnormalities. We aimed to explore the structural differences between PD patients with and without the respiratory symptoms. METHODS: Patients with PD were recruited from the Department of Psychiatry at Korea University Anam Hospital. Respiratory subtype (RS) was diagnosed when at least 4 out of 5 of the following respiratory symptoms were present during the panic attack: fear of dying, chest pain/discomfort, shortness of breath, paresthesias, and a choking sensation. We acquired high-resolution MRI scans and used FreeSurfer to obtain a measure of cortical thickness for each patient. RESULTS: Cluster based analysis revealed significantly decreased cortical thickness in the left hemisphere in the caudal-middle-frontal, superior frontal, and posterior parietal areas in the RS group. No significant difference was observed in any of the limbic areas. CONCLUSION: Respiratory symptoms of panic disorder were associated with a reduction in cortical thickness in the left frontal and parietal areas. This finding leads to the assumption that the frontoparietal network is the crucial component in a larger cortical network underlying the perception of dyspnea in RS.
