Paragangliomas of the mediastinum are rare neoplasms. We report a case of a unsuspected mediastinal paraganglioma in 55-year-old man. The mediastnal tumor was accidentally discovered on a chest roentgenogram and there was no history of hypertension, sweating, flushing and headache. Surgical resection was difficult with bleeding and fluctuation of arterial blood pressure reaching up to 190/130 mmHg with tachycardia. The blood pressure was controlled with nitroglycerine and tachycardia controlled with beta-blocker. After tumor resection, hypotension was treated with dopamine and blood transfusion. Postoperative recovery was satisfactory and the patient discharged after 20 days. The diagnosis of aorticosympathetic paraganglioma was established by histologic examination.

Purpose: This study developed an integrated health management program for metabolic syndrome in psychiatric patients and examined its effects on self-efficacy, healthy lifestyle, physiological indicators, knowledge of metabolic syndrome, attitudes toward healthy behavior, and social support. Methods: A non-equivalent control group pretest posttest design was used. The participants were 65 psychiatric patients with metabolic syndrome in psychiatric rehabilitation centers, with 33 in the experimental group and 32 in the control group. The experimental group participants engaged in daily mobile application and walking exercises three times a week for more than 40 minutes over 8 weeks, while those in the control group were provided education booklets. The outcomes were measured using self-report questionnaires, anthropometrics, and blood analyses. Intervention effects were analyzed using the independent t-test, Mann—Whitney U test, ANCOVA, and Ranked ANCOVA. Results: The experimental group showed a significant increase in self-efficacy (F = 8.85, p = .004, ηp2 = .13) and knowledge of metabolic syndrome (t = 2.60, p = .012, d = 0.60) compared to the control group. Additionally, the experimental group demonstrated a significant decrease in waist circumference (Z = - 2.34, p = .009, d = 0.58) and body mass index (Z = - 1.91, p = .028, d = 0.47) compared to the control group. Conclusion The integrated health management program for psychiatric patients with metabolic syndrome is effective in improving self-efficacy and knowledge of metabolic syndrome and decreasing physiological indicators such as waist circumference and body mass index.

A choledochocele is an expanded sac of the duodenal side of the distal common bile duct (CBD), and is categorized as a type III choledochal cyst. Unlike other choledochal cysts, it can be easily overlooked because of its very low prevalence, non-specific clinical symptoms, and lack of distinctive radiological findings. However, a patient having a repeated pancreaticobiliary disorder with an unknown origin, frequent abdominal pain after cholecystectomy, or repeated non-specific gastrointestinal symptoms can be suspected as having a choledochocele, and a more accurate diagnosis can be achieved via endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound. Because it rarely becomes malignant, a choledochocele can be treated via endoscopic sphincterotomy (EST) and surgical treatment. The authors were able to diagnose choledochocele accompanied by a stone in a patient admitted to the authors' hospital due to cholangitis and pancreatitis. The patient's condition was suspected to have been caused by a distal CBD stone detected via multiple detector computed tomography and ERCP, and was successfully treated via EST.

Primary thyroid lymphoma (PTL) is a relatively rare disease, accounting for less than 0.5~5% of all thyroid malignancies. We encountered two cases of a primary thyroid lymphoma with Hashimoto's thyroiditis; one in a 63-year-old man and the other in a 79-year-old woman. The first case was a mucosa-associated lymphoid tissue lymphoma, and the other was a diffuse large B-cell lymphoma. Both patients underwent surgery and radiotherapy after being diagnosed using fine-needle aspiration cytology (FNAC). Both patients recovered well with no recurrence throughout the study period. The role of the surgeon in the treatment and diagnosis of thyroid lymphoma has been reduced due to the development of FNAC and combination therapy with chemotherapy and radiotherapy. On the other hand, surgery can be an effective treatment option for PTL confined to the thyroid, for achieving a definitive diagnosis, and in the treatment of patients with an airway obstruction.

BACKGROUND: Asthmatic patients frequently suffer cold-weather-associated respiratory symptoms. The sensitivity, specificity, accuracy and diagnostic value of isocapnic hyperventilation of cold air(IHCA) using a multistep method was investigated in patients suspected to have asthma. METHOD: One hundred and 29 adult patients who had an IHCA performed between july 1999 and December 2000, had an methacholine bronchoprovocation test because of a clinical suspicion of asthma. RESULTS: According to strict criteria, 50 were defined as asthmatics and 79 as symptomatic nonashmatics. There were no differences in age, sex and smoking state between the asthmatic and symptomatic nonasthmatic groups. There was a significant decrease in the percentage reduction in the forced expiratory volume in 1 second(FEV1) after the IHCA between the asthmatics(-10.0±6.8%) and the symptomatic nonasthmatics(-2.3±2.5%). The factors associated with a reactivity to IHCA were FEV1/FVC, FEF25-75/FVC and FEV1(% of predicted). The accuracy was highest using a 7% fall in FEV1; the sensitivity was 76% and the specificity 96%. CONCLUSION: IHCA is a specific, although not a sensitive, test for diagnosing asthma in adult patients. Furthermore, the diagnostic cut-off value of the different methods of IHCA need to be determined.

Cerebral malaria means that the patient with demonstrable asexual forms of Plasmodium falciparum in peripheral blood smear who have disturbed mental state and in whom other causes of encephalopathy, such as bacterial, fungal, or viral meningoenoephalitides, drug intoxications other metabolic disease have been excluded. In cerebral malaria, the mortality rate is up to 30% and most of death is within 96 hours, so is known as neurological emergency that urgent treatment should be required. A 42 years old male patients admitted our emergency room with spiking fever 2 days before admission and drowsy mental state at the moming of admission day. The patient traveled in Africal 2 weeks ago. On physical and neurologic examination, the hepatomegaly, drowsy mental state and divergent eyeball was observed. Brain CT scan was normal but pulmonary edema was seen in chest PA and mild increased protein(76mg/dl) was observed in spinal tapping. In peripheral blood smear, severe thrombocytopenia and trophozoa of ring form and band form wer found so diagnosed as mixed infected cerebral malaria. The patient was started the treatment of chloroguine and tetracycline and recovered 2 weeks after treatment. Cerebral malaria should be once considered as differential diagnosis in patients with unknown origin fever and mental confusion in intemalized society like modem.

It is often problematic to diagnose T-cell lymphoproliferative disorders of the skin because of the difficulty in establishing clonality in paraffin-embedded tissue. We used polymerase chain reaction single strand conformational polymorphism (PCR-SSCP) and heteroduplex analysis in paraffin embedded tissue to detect clonal rearrangement of T-cell receptor gamma (TCRgamma) gene in 17 T-cell lymphoproliferative disorders and 6 atypical lymphoproliferative diseases. We used polymerase chain reaction to detect TCR beta gene rearrangement in 8 of 17 cases which did not show TCRgamma gene rearrangement. Jurkat cell lines were used as monoclonal controls. DNA was extracted from 5 biopsies of T-cell lymphomas, 10 biopsies of mycosis fungoides, 2 biopsies of lymphomatoid papulosis, and 6 biopsies of atypical lymphoproliferative lesions. We detected monoclonality in 5 of 5 T-cell lymphoma cases, 2 of 2 lymphomatoid papulosis cases, 6 of 10 mycosis fungoides cases, and 2 of 6 atypical lymphoproliferative disease cases. We conclude that nonradioactive PCR-SSCP for TCR gene rearrangement analysis is a useful adjunct to routine histological and immunophenotypic methods in the diagnosis of cutaneous T cell lymphoproliferative disorders in paraffin embedded tissue.

Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease. Only a few patients reach adulthood without surgical correction. Unrepaired TOF patients with mild to moderate right ventricular outflow tract (RVOT) obstruction may be clinically silent until adulthood. TOF with hypoxic spells present as periods of profound cyanosis that occur because of almost total RVOT obstruction. So, hypoxic spell typically occurs in a crying infant but is rare in an adult. In this report, we presented a case of a 75-year-old patient with uncorrected TOF presenting with hypoxic spell, consequent pulmonary hypertension and chronic heart failure. This is the oldest case of natural survivor with uncorrected TOF in Korea and the oldest patient presenting hypoxic spell worldwide.

BACKGROUND: The purpose of this study was to determine the clinical effective dose of alfentanil required for successful tracheal intubation during inhalation induction using 5% sevoflurane without neuromuscular blockade in children sedated with ketamine. METHODS: Twenty-one children, aged 3-10 years, undergoing surgeries under general anesthesia were enrolled into the study. All patients were premedicated with 0.004 mg/kg glycopyrrolate intramuscularly 30 min before anesthesia.To facilitate separation of the child from the parents, intravenous 1 mg/kg ketamine was given prior to transfer into the operating room.After inhalation induction with 5% sevoflurane and 100% oxygen, pre-determined dose of alfentanil was injected over 20 sec. The dose of alfentanil was determined by modified Dixon's up-and-down method (2microgramkg as a step size starting from 12microgramkg).The study ended when six independent pairs of patients, who manifested cross over from 'failure' to 'success' for tracheal intubation, were recruited. RESULTS: In 50% of children, the effective bolus dose (ED50) (95% confidence intervals) of alfentanil for successful tracheal intubation was 7.2microgram/kg (6.3-8.1microgram/kg) during sevoflurane inhalation induction.From isotonic regression, 95% effective dose (ED95) (95% confidence intervals) of alfentanil was 9.9microgram/kg (2.2-16.0microgram/kg). CONCLUSIONS: During inhalation induction using 5% sevoflurane without neuromuscular blockade after ketamine sedation, the ED50 and ED95 of alfentanil for successful tracheal intubation were 7.2 microgram/kg and 9.9microgram/kg in children, respectively.

BACKGROUND: Patients with chest pain are common among outpatients. Several researches shows that chest pain patients can suffer from psychiatric illnesses such as hypochondriasis, depression, anxiety, somatization, panic disorder and so on. This study aims to examine the pschogenic symptoms in patients with noncardiac chest pain METHODS: In this study, the 98 people who have undergone treadmill test for chest pain during the three months from June 1st to September 30 of 1998 were selected, and the 98 patients were asked to respond to the prepared questionnaire and SCL-MPD(symptom check list-minor psychiatric disorders) before they underwent treadmill test. And then, they were classified into two groups. One group consisted of patients with noncardiac chest,pain, and the other group of patients with cardiac chest pain. These two groups were compared in 10 measures, and the compared results were analyzed by t-test. RESULTS: Among the 25 patients with cardiac chest pain, 15 patients were males and 10 patients (38%) were females, and among the 44 patients with noncardiac chest pain, 31 patients (70%) were males, 13 patients (30%) were females. The average age was 47 years old. The average age in patients with noncardiac chest pain was 48, and the 46 for those patients with cardiac chest pain . In the statistical analysis between the patients with cardiac chest pain and those with noncardiac chest pain, significant difference(p<0.005) was shown in the measures such as somatization, depression, phobic anxiety, obsessive-compulsive, neurasthenic, hypochondriacal, anxiety, anger-hostility, interpersonal sensitivity. CONCLUSIONS: As in the analysis the patients with noncardiac chest pain showed significant difference in the symptom check list-minor psychiatric disorder compared to those with cardiac chest pain. We conclude that primary care physician should take more interest in evaluating psychiatric symptoms in patients with noncardiac chest pain.
