OBJECTIVES: Contemporary empirical studies have suggested high rates of comorbid attention-deficit hyperactivity disorder(ADHD) or obsessive compulsive disorder(OCD) in children with tic disorders. Not infrequently, ADHD or OCD is as source of greater impairment than are the tic symptoms. The studies in the pathophysiology of tic disorder have implicated abnormalities of dopamine, serotonin and norepinephrine. The studies in pathophysiology of ADHD or OCD also have implicated abnormalities of dopamine, serotonin and norepinephrine. This study was purposed to examine the differences in tic severities and in the levels of plasma homovanillic acid(HVA) and 5-hydroxyin-doleacetic acid(5-HIAA) according to the presence of comorbid ADHD or OCD in patients with chronic tic disorders. METHODS: In fifty chronic tic patients, OCD or ADHD was also diagnosed. And then tic symptoms, obsessive-compulsive symptoms, and attention-deficit hyperactive symptoms were assessed using Yale global tic severity scale(YGTSS), Leyton obsessional inventory-child version(LOI-CV), and Conners parent rating scale. The plasma HVA and 5-HIAA levels were measured using high performance liquid chromatography with electrochemical detection method. RESULTS: Fifty-eight percent of the patients with chronic tic disorders had comorbid ADHD or OCD. But severities of tic did not differ regardless of the presence of comorbid ADHD or OCD. There was a significant positive correlation between tic severities and plasma HVA levels but none between tic severities and plasma 5-HIAA levels. There was a significant inverse correlation between resistance and interference scores and plasma 5-HIAA levels. Plasma HVA levels showed significant positive correlations with plasma 5-HIAA levels. CONCLUSION: These results showed that tic severities didn't vary according to the presence of comorbidities, and that tic severities were correlated with plasma HVA levels, not with plasma 5-HIAA levels. These results suggested that the pathophysiology of chronic tic disorder was strongly correlated with abnormalities of dopaminergic system.

Diagnosis of a thymic carcinoid was made on transthoracic fine needle aspiration in a 36-year old woman who had an anterior mediastinal mass on chest X-ray and CT scan. The aspiration smears showed numerous anastomosing ribbons and cords of small round tumor cells. The tumor cells had slightly eccentric nuclei and some granular cytoplasm. The small and uniform nuclei of the tumor cells had finely granular chromatin and thin nuclear membrane. The cytologic diagnosis of a carcinoid was confirmed on histopathologic, immunohistochemical, and electromicroscopic examination of surgical specimen.

OBJECTIVES: In an effort to improve hearing aid users’ satisfaction, recent studies on trainable hearing aids have attempted to implement one or two environmental factors into training. However, it would be more beneficial to train the device based on the owner’s personal preferences in a more expanded environmental acoustic conditions. Our study aimed at developing a trainable hearing aid algorithm that can reflect the user’s individual preferences in a more extensive environmental acoustic conditions (ambient sound level, listening situation, and degree of noise suppression) and evaluated the perceptual benefit of the proposed algorithm. METHODS: Ten normal hearing subjects participated in this study. Each subjects trained the algorithm to their personal preference and the trained data was used to record test sounds in three different settings to be utilized to evaluate the perceptual benefit of the proposed algorithm by performing the Comparison Mean Opinion Score test. RESULTS: Statistical analysis revealed that of the 10 subjects, four showed significant differences in amplification constant settings between the noise-only and speech-in-noise situation (P<0.05) and one subject also showed significant difference between the speech-only and speech-in-noise situation (P<0.05). Additionally, every subject preferred different β settings for beamforming in all different input sound levels. CONCLUSION: The positive findings from this study suggested that the proposed algorithm has potential to improve hearing aid users’ personal satisfaction under various ambient situations.

PURPOSE: It is important to select and use kinds of Inhaler appropriate to the age of the patient and severity of symptoms. Several kinds of Inhaler have been developed and recommended according to each inhaler's resistance and usage method. We evaluated the usable age of 4 inhalers (turbulent flow inhalers, multi unit dose inhalers, breath actuated MDI, and autohalers) by measuring peak inspiratory flow(PIF) using In-Check(TM) Inspiratory Flow Meter. METHODS: Ninety three patients aged from 3 to 7 years(mean 57+/-12.9 mo.) who had admitted to CHA hospital from July 2000 to April 2001 were enrolled. Study patients were divided into 4 groups according to age:3-4 years of age(group A, n=31), 4-5 years of age(group B, n=32), 5-6 years of age(group C, n=18), and 6-7 years of age(group D, n=12). RESULTS: Out of total 93 patients, 23(71%), 27(84%), 17(94%) patients of each group A, B, C and all 12 patients of group D could use the 4 types of inhaler through adequated education. In all four groups, height, body weight and age were significantly correlated(P<0.05). Usable age, height and weight of children who can use turbulent flow inhaler(TFI) were each 8 year 7 month old, 144 cm, 32.0 kg, and those of multi unit dose inhaler(MUD) were 2 year 10 month old, 92 cm, 12.0 kg. Also that of breath-actuated MDI were 1 yr 8 months, 83 cm, 8.5 kg and that of autohaler were 2 yr 8 months, 91 cm, 11.0 kg. CONCLUSION: We concluded that the ability to use inhalers correlated with height, weight and age of the patients. Multi unit dose inhalers, Breath actuated MDI and Autohaler are useful after 3 years of age through adequate education.

OBJECTIVE: To study the prevalence, indications, and outcome of cesarean hysterectomy in women delivered at the Gil Medical Center, Gacheon Medical School. METHOD: This is a retrospective study of all cases of cesarean hysterectomy performed between January 1995 and December 1999. RESULTS: The incidence of cesarean hysterectomy was 0.4% (122/31,481). Cesarean hysterectomy was performed in 100 of 17,829 cesarean sections (0.6%) and in 22 of 13,652 vaginal deliveries(0.2%). The higher the age and the parity of patients, the higher the incidence of cesarean hysterectomy was noted. The most common indication of cesarean hysterectomy was uterine atony(50 cases, 41.9%), followed by 25 cases of placenta previa with adhesive placenta(20.5%), 14 cases of adhesive placenta(11.5%), 11 cases of uterine myoma with pregnancy(9.0%), 9 cases of uncontrolled bleeding with placenta previa(7.4%), 7 cases of uterine rupture(5.7%) and 6 cases of extension of uterine incision(4.9%). All patients who had cesarean hysterectomy received transfusion from 0 pint to 78 pints. Live births were 115 cases(94.3%) and 3 infants were still birth(2.5%). Four infants were dead during early neonatal period(3.3%), so perinatal mortality rate was 5.7%. The postoperative complications were bladder injury, ureteral injury, febrile morbidity, disseminated intravascular coagulopathy, hematoma, wound disruption, postpartum cardiomyopathy, and vaginal stump bleeding. There was two maternal deaths due to acute, severe hemorrhage and DIC. CONCLUSIONS: Cesarean hysterectomy remains a necessary procedure for life saving during abdominal and vaginal deliveries. The procedure itself is usually associated with considerable perioperative morbidity. Obstetricians should identify patients at risk and anticipate the procedure and complications.

PURPOSE: Neuroendocrine carcinomas of the stomach account for only about 0.3% of all gastric tumors. The prognosis of this disease is very poor compared with the common type of gastric adenocarcinoma. The purpose of this retrospective study was to review the clinicopathologic features of 18 cases of this unusual gastric tumor and to establish a treatment strategy for this tumor. MATENRIALS AND METHODS: Excluding 2 cases of non-curative resection and 1 case of operative mortality, 18 cases of typical neuroendocrine carcinoma who had curative resection from January 1991 to December 2000 at Asan Medical Center were analyzed; 6841 gastric cancer patient were treated surgically during the same period. RESULTS: The mean age at the time of diagnosis was 58.6 years (range: 35~75 yr). Sixteen patients were male, and two were female. Eleven tumors (61.1%) developed in the lower part of the stomach, three (16.7%) in the middle part, and three (16.7%) in the upper part. One tumor involved the entire stomach. Eight cases (44.4%) were Borrmann type 2, and six case (33.3%) were Borrmann type 3. The mean tumor size was 6.94 cm (range: 0.6~15 cm). Nine cases (50%) showed recurrence of the disease, and eight of them died within 20 months. Of the nine recurred cases, 7 cases (77.8%) showed liver metastasis. The mean disease-free interval was 6.8 months (range: 2.5~11 months) after surgical resection, and the mean survival was 17.9 months (range: 8~40 months) for recurrence cases. One patient with liver metastasis was treated with a liver-wedge resection just after diagnosis and was still alive for 37.5 months postoperatively. There were 9 deaths after the median follow-up period of 40 months (range: 8~72 months). CONCLUSION: Gastric neuroendocrine carcinomas frequently recur at the liver, even in early stage cancer, and have a poor prognosis. We experienced a case of successful control of hepatic metastasis by surgical resection and a case of a small cell carcinoma which was successfully controlled with systemic chemotherapy.

BACKGROUN: Talc sclerotherapy is widely used for symptomatic malignant pleural effusion. The object of this study was to evaluate the outcome of talc slurry sclerotherapy, and to compare the efficacy of the small-bore catheter with that of chest tube in sclerotherapy of malignant pleural effusion. METHODS: From January 2000 to May 2002, 37 patients with malignant pleural effusion were enrolled and randomized to the chest tube (28F, n=17) or the small-bore catheter (14F, n=20) groups. The majority of patients had lung cancer (n=33, 89%) and two had breast cancer. The median age was 55 years. After verification of reexpansion of lung on chest radiogram. five grams of purified asbestos-free talc in 50 mL of normal saline were used for talc slurry sclerosis. The success of the procedure was defined as daily drainage below 50 mL within 1 week after talc slurry instillation. Side effects of the sclerotherapy and complications were compared by the drainage method and the recurrence rates in 3, 6 and 9 months were evaluated. RESULTS: Initial success rates of sclerotherapy by small-bore catheter was 80% and that of chest tube was 70.5% (p=0.07). The most common early complication after talc slurry instillation was pain followed by fever. But procedure related mortality or respiratory failure was not developed. The mean duration of drainage by small-bore catheter was 8.2days and that of chest tube was 8.8days (p=0.60). But the catheter-related complications of pain, subcutaneous infection and, emphysema were significantly less in the small-bore catheter group than the chest tube groups (15% vs 88%, 5% vs 23.5%, 0% vs 17.5% respectively) There was no statistically significant difference between the two groups in the recurrence rate at 3 months (37.5% for the small-bore catheter vs. 33.3% for the chest tube, p=0.45), 6 months (56.3% vs. 58.3%, p=0.75), and 9 months (87.5% vs. 83.3%, p=0.65). CONCLUSION: Talc slurry sclerotherapy via chest tube or small-bore catheter was a safe and effective method for the treatment of symptomatic malignant pleural effusion. But small-bore catheters are preferred to the chest tube in the sense of catheter-related complications.

Pheochromocytoma, the catecholamine-producing tumor of chromaffin tissue, is associated with a curable form of hypertension. Recently we report the case of a 59 year-old male admitted for an acute myocardial infarction and who subsequently developed late recurrent severe ventricular arrhythmia coincident with transient hypertensive episodes. A pheochromocytoma was diagnosed on the basis of the urinary concentration of catecholamines and computerized tomography of the adrenal glands. After stabilization of his cardiac rhythm and blood pressure with alpha adrenergic blockade, the left adrenal gland, which contained the tumor, was subsequently resected. The diagnosis of a pheochromocytoma should be considered when recurrent ventricular arrhythmia are associated with intermittent hypertension after acute myocardial infarction.
