BACKGROUND: The purpose of this study was to measure and compare the optimum depth of the internal jugular venous catheterization between the right and left side. METHODS: Forty-four patients were enrolled for this study and divided into two groups (22 patients each). The optimum depth of the catheterization was calculated using the sum of two component (A and B); the advanced length of the catheter from the level of the cricoid cartilage (A) and the distance from the catheter tip to the junction of the superier vena cava and right atrium (B). RESULT: The optimum depths of the internal jugular venous catheterization were 16.0 1.0 cm (right) and 18.4 1.5 cm (left) respectively. Left side was significantly longer than right side (p<0.05). In this study, we experienced some complications; arterial punctures (5 cases) and migration of the catheter to the opposite subclavian vein (1 case). Five complications were associated with left internal jugular venous cannulation and one was associated with the right side cannulation. CONCLUSION: We concluded that the optimum depth of the internal jugular venous catheterization was longer in the left side than in the right side.

BACKGROUND: In spite of relative high risk of extrapyramidal side effect and tardive dyskinesia, it is common clinical practice to use antipyschotics in treatment of bipolar I disorder. But in Korea, there has been few study about clinical factors related with antipsychotics treatment in bipolar disorder patients. So the author studied about the clinical factors related with antipsychotics treatment in bipolar inpatients focusing on the comparison of risperidone and classical antipsychotics. METHOD: By reviewing medical record retrospectively, datas about patient-related, illness-related, and treatment-related clinical factors on antipsychotics use were collected. Association between antipsychotics dose and duration and clinical factors were analysed by statistical method. RESULTS: Aggressive behavior was only statistically significant factor associated with antipsychotics use. And in the case of aggression, maintenance dose of risperidone was not changed(p=0.84), but dose of classical antipsychotics was increased significantly(p=0.005). Total hospital days and antipsychotics treatment duration showed no difference between risperidone and classical antipsychotics treatment groups. CONCLUSION: Clinical factors associated with antipsychotics use was aggressive behavior. In the case of aggression, risperidone required lesser dose increment compared with classical antipsychotics.

OBJECTIVES: This study was performed to investigate the incidence and the clinical significance of inlet patch of heterotopic gastric mucosa in Koreans. This lesion can be found by close observation around the upper esophageal sphincter during upper gastrointestinal endoscopy. METHODS: From March 1, 1996 to July 8, 1996, at Kwak's hospital, randomly selected 271 patients undergoing routine diagnostic upper gastrointestinal endoscopy were included in this study. Patients with the inlet patch were confirmed by histology. Clinical symptoms observed through medical history were recorded. RESULTS: Twenty-six cases(9.6%) of the 271 patients studied had heterotopic gastric mucosa which was found at or just below the upper esophageal sphincter, varing from 3 to 30mm in diameter. It was velvety red in color and distinct from the surrounding normal squamous esophageal mucosa, resembling the Z-line at the esophagogastric junction. Parietal cells were identified in all 18 cases in which biopsy specimen contained deep glands, and chief cells were found in 14 cases. Histologically, fundic gland type was most frequent. The symptoms were relatively mild, 5 out of 6 patients who complained of throat discomfort were relieved by H2 antagonists. CONCLUSION: In Koreans the incidence of heterotopic gastric mucosa in the upper esophagus was similar to the reports from western countries unlike Barrett's esophagus. The etiology of these patches appeared to be congenital rather than acquired from reflux of gastric acid. This was supported by its location in the proximal esophagus and lack of correlation with reflux esophagitis. It must be considered as one of the differential diagnosis of a patient who complains of throat discomfort during diagnostic upper gastrointestinal endoscopy. Attention needs to be paid to find possible development of complications such as stricture and adenocarcinoma in patients with the inlet patch of heterotopic gastric mucosa.

A case of pulmonary alveolar proteinosis is reported. Most of the alveolar spaces were filled with amorphous deep eosinohilic material which revealed strong positive reaction to periodic acid-Schiff staining. Electron microscopic observation of this material showed numerous lamellar bodies in the alveolar spaces and cytoplasms of alveolar macrophages. A part of them were concentric multilamellated type A lamellar bodies and the other were finger printlike type B bodies. Combined type A and type B lamellar bodies were rarely present. From the above features it is suggested that both type A and B lamellar bodies could be transformed one another and those lamellar bodies may be originated from pulmonary surfactant.

Schwannoma is a benign encapsulated nerve sheath tumor and is histologically characterized by a mixture of Antoni type A and B tissue. A preoperative diagnosis of schwannoma by fine needle aspiration cytology or by any other means is important to preserve clinically important nerves. Therefore, it is necessary to make a specific cytological diagnosis of nerve sheath tumor. However, there are a few reports regarding cytological features of schwannoma in Korea. We experienced seven cases of solitary schwannoma and here we report their characteristic cytological features with a review of literatures. The characteristic features of schwannoma on cytology were the presence of both Antoni type A and B tissue. The cytologic findings common to all cases of schwannoma generally corresponded to the histologic findings of Antoni type A tissue, consisting of fragments of tightly cohesive fascicles with variable cellularity. Dense fibrillary substances were found, along with palisading nuclei and Verocay bodies. Individual tumor cells consisted of cohesive cells having spindle or oval nuclei, with pointed ends and indistinct cell borders. Variation in nuclear size and shape was also present. The Antoni type B consisted of scattered wavy or short spindle cells and some histiocytes and lymphocytes in the abundant myxoid background with formation of microcysts. Immunohistochemistry for S-100 protein revealed a uniformly strong positive reaction and was helpful to make more accurate diagnosis of schwannoma.

Pelvic lipomatosis is a condition characterized by a nonmalignant overgrowth of normal fat in the perirectal and perivesical spaces in the pelvis which may be to occur obstructive uropathy. On cystography the full bladder has an abnormal shape as a gourd, banana, pear or inverted tear-drop. Compulerized tomography shows the bladder and rectosigmoid surrounded and displaced by homogeneous tissue with a low attenuation coefficient and the CT features provide diagnostic proof or pelvic lipomatosis. We present a case of pelvic Lipomatosis.

Abdominal actinomycosis is a rare and chronic progressive disease, especially in children. Clinically, it has non-specific symptoms and diagnostic findings as well as low prevalence, making it very difficult to diagnose prior to intraoperative pathological confirmation. For this reason, abdominal actinomycosis is commonly misdiagnosed as appendicitis. After the histopathological diagnosis of abdominal actinomycosis is made, patients should be administered an appropriate antibiotic such as penicillin. Here we describe a case of appendiceal actinomycosis in an 18-year-old girl who was initially diagnosed with acute appendicitis.

Only a few case studies describe reversible parkinsonism after organophosphate poisoning and their brain imagings are found to be normal. However, we experienced chronic, irreversible parkinsonism by acute organophosphate poisoning with bilateral basal ganglia lesions found on a brain MRI. We suggest that brief, large amounts of organophosphate intoxication can produce irreversible parkinsonism according to individual susceptibility and further studies including the investigation of insecticides as an environmental factor of parkinsonism should be done using neuroimagings.

The Peutz-Jeghers syndrome is an autosomal dominant disease characterized by hamartomatous polyps in the gastrointestinal tract and mucocutaneous melanin pigmentation. Although these polyps are believed to have little potential for malignancy, and the disease was believed to have a relatively benign course, it recently has been recognized that patients with this syndrome are at increased risk for the development of cancer at gastrointestinal and nongastrointestinal sites. A 33-year-old male patient was admitted because of vomiting and abdominal pain for 3 months duration. A diagnosis of Peutz-Jeghers syndrome was made 3 years ago by multiple hamartomatous polyps confined to the colon and mucocutaneous pigmentation. A barium study showed abrupt string like luminal narrowing at the 4th portion of the duodenum. On laparotomy, there was an annular constricting mass involving the serosa of duodenum with multiple metastasis to liver, so a segmental resection of small bowel followed by chemotherapy was performed. The histologic finding was adenocarcinoma.
