The importance of the ticks in medical field has been emphasized because of their association with and transmission of various diseases. We report herein a case of tick bite in a 55-year-old male farmer, who visited our hospital on July 2, 1981 with a parasite attached on right lower flank and rice to small pea sized, pruritic erythematous papular skin eruptions on chest and right lower flank. The skin lesions disappeared completely with.in five days after removal of the parasite, which was identified with an adult female tick which belongs to Genus Ixodes.

BACKGROUND: The statistical analysis is an essential procedure ensuring that the results of researches are based on evidences rather than opinion. The purpose of this study is to evaluate which statistical techniques are used and whether these statistical methods are used appropriately or not in the journal of Tuberculosis and Respiratory Diseases. MATERIALS AND METHODS: We reviewed 185 articles reported in the journal of Tuberculosis and Respiratory Diseases in 1999. We evaluated the validity of used statistical methods based upon the checklist that was developed on the basis of the guideline for statistical reporting in articles for medical journals by International Committee of Medical Journal Editors. RESULTS: Among 185 articles, original articles and case reports were 110 (59.5%) and 61 (33.0%) respectively. In 112 articles excluding case reports and reviews, statistical techniques were used in 107 articles (95.5%). In 94 articles (83.9%) descriptive and inferential methods were used, while in 13 (11.6%) articles only descriptive methods were used. With the types of inferential statistical techniques, comparison of means was most commonly used (64/94, 68.1%), followed by contingency table (43/94, 45.7%) and correlation or regression (18/94, 19.1%). Among the articles in which descriptive methods were used, 83.2% (89/107) showed inappropriate central tendency and dispersion. In the articles in which inferential methods were used, improper methods were applied in 88.8% (79/89) and the most frequent misuse of statistical methods was inappropriate use of parametric methods (35/89, 39.3%). Only 14 articles (13.1%) were satisfactory in utilization of statistical methodology. CONCLUSION: Most of the statistical errors found in the journal were misuses of statistical methods related to basic statistics. This study suggests that researchers should be more careful when they describe and apply statistical methods and more extensive statistical refereeing system would be needed.

Toothbrush swallowing is a rare event. Because no cases of spontaneous passage have been reported, prompt removal is recommended to prevent the development of complications. Most swallowed toothbrushes have been found in the esophagus or the stomach of affected patients, and there has been no previously reported case of a toothbrush in the colon. Here, we report a case of a swallowed toothbrush found in the ascending colon that caused a fistula between the right colon and the liver, with a complicating small hepatic abscess. This patient was successfully managed using exploratory laparotomy. To our knowledge, this is the first documented case of a swallowed toothbrush found in the colon.

A Sengstaken-Blakemore (S-B) tube has been widely used to treatment of bleeding esophageal varices. It controls bleeding in 50~92% of cases and provide more time to plan future management. However, there are a number of complications with its use, some of which are lethal. We recently observed a very unusual complication of a S-B tube, namely an impaction of the gastric balloon at the gastroesophageal junction, which could not be deflated by removing the clamps and suctioning the air with a syringe. The gastric balloon was punctured endoscopically with needle knife and deflated. The S-B tube was then be easily removed.

Irritable bowel syndrome (IBS) is a gastrointestinal disorder characterized by chronic abdominal pain and altered bowel habits in the absence of any organic cause. As the clinical manifestations are very diverse and associated with nonspecific symptoms, research seeking to identify organic causes to rule out IBS and to enable differential diagnosis is required. A 24-year-old man was referred to our hospital for specialized management of IBS. He had a 7-month history of intermittent epigastric and lower abdominal pain. On the basis of clinical examination, he was diagnosed with IBS and administered medication at a primary clinic. However, his symptoms did not improve after treatment. We performed capsule endoscopy at our hospital and identified a parasite (Ancylostoma duodenale) in the proximal jejunum. We therefore report a case of parasitic infection found by additional examination while evaluating symptoms associated with a previous diagnosis of refractory IBS.

OBJECTIVES: The association of workplace cumulative noise exposure and blood pressure was investigated in this study using cross-sectional design. METHODS: The study population comprised 852 manufacturing male workers of whom occupational health examination data, questionnaire and personnel records were available. Workplace ambient noise monitoring data was used for calculating individual cumulative noise exposure level. Mean of each systolic and diastolic blood pressure of occupational health examination data was used for individual systolic and diastolic blood pressure level. Possible confounding variables including family history of hypertension, smoking habit, alcohol drinking habit were collected by questionnaire. On the basis of job location and duration of work at the location, a cumulative time-weighted average noise level was calculated for each workers. According to this cumulative noise exposure level, each study subject was categorized as low noise exposure group, moderate noise exposure group, high noise exposure group, very high noise exposure group. Among noise exposure groups, mean of systolic and diastolic blood pressure was compared after adjusting possible confounding variables such as age, body mass index, serum cholesterol level, family history of hypertension, smoking history, alcohol drinking habit. RESULTS: After adjusting possible confounding variables, noise exposure group was significant explanatory variables for both systolic and diastolic blood pressure, and mean of both systolic and diastolic blood pressure of very high exposure group was higher than that of low exposure group. CONCLUSIONS: These findings suggested that the high cumulative noise exposure might elevate the blood pressure.

OBJECTIVE: Delayed cerebral ischemia due to vasospasm after aneurysmal subarachnoid hemorrhage (SAH) is a leading cause of morbidity and mortality. Recent reports have confirmed that intra-arterial infusion of calcium-channel blockers, which are widely used to counteract vasospasm, is effective for treating SAH with a low risk of complications. Here we report on our experience with intra-arterial nicardipine angioplasty in a consecutive series of 32 patients with SAH. METHODS: This retrospective review evaluated a series of 32 consecutive patients with symptomatic vasospasm that was treated with intra-arterial nicardipine. The patients included in the study were diagnosed with aneurysmal SAH between January 2007 and February 2011. All the patients underwent microsurgical clipping or endovascular coiling. Angioplasty using intra-arterial nicardipine was performed in those patients who were refractory to medical therapy such as triple H therapy. RESULTS: The 32 patients underwent a total of 55 procedures. The total amount of nicardipine used in each angioplasty procedure did not exceed 12 mg, with a maximum dose of 3 mg for each vessel. The Glasgow Coma Scale (GCS) score improved in all patients with an average improvement of 2.4 (range : 1~5). During angioplasty, there were no complications such as thromboembolic events and/or acute transitory spasm. The clinical results were evaluated using the modified Rankin Scale (mRS). Good outcomes (mRS 0~2) were determined in 19 (63.3%) of the 30 patients. The 11 patients (36.7%) with poor outcomes initially had a high Hunt and Hess grade (III or IV) or they had intra-operative complications (mRS: 3~6). CONCLUSION: Our study results support the effectiveness and safety of low-dose nicardipine when performing intra-arterial angioplasty for the treatment of vasospasm after aneurysmal SAH.

Massive thoracoabdominal aortic thrombosis is a rare finding in patients with iatrogenic Cushing syndrome in the absence of any coagulation abnormality. It frequently represents an urgent surgical situation. We report the case of an 82-year-old woman with massive aortic thrombosis secondary to iatrogenic Cushing syndrome. A follow-up computed tomography scan showed a decreased amount of thrombus in the aorta after anticoagulation therapy alone.

BACKGROUND: One of the characteristics of hypoglycemic encephalopathy (HE) is selective vulnerability of different brain regions. CASE REPORT: We observed a patient with unilateral HE affecting the right internal capsule and the subcortical white matter. The patient had a preexisting stroke in the opposite hemisphere. The hemisphere that was affected by HE exhibited greater regional blood flow (single positron-emission tomography) and higher fractional anisotropy (diffusion-tensor imaging) than the unaffected hemisphere. CONCLUSIONS: This case suggests that the degree of metabolism required to maintain the function of brain structures and neuronal integrity is an important factor determining the selective vulnerability in HE.

Pyothorax-associated lymphoma is a distinct type of malignant lymphoma composed of lymphocytes, mostly of a B-cell nature. It occurs in patients with a long history of pyothorax and is strongly associated with Epstein-Barr virus infection. We experienced a case of pyothorax-associated lymphoma in a 66-year-old male. The patient had chronic pyothorax after tuberculous pleurisy was treated about 37 years earlier and was hospitalized for a recently occurring chest wall mass. A core needle biopsy of the chest wall mass led to a diagnosis of diffuse large B-cell lymphoma. Pyothorax-associated lymphoma is rare in Korea, but should be considered in patients with chronic pyothorax and a recently occurring pleural mass.
