Asbestos exposure may cause asbestosis, pleural plaques and benign pleural disease, and may give a predisposition to malignant mesothelioma in occupationally exposed workers. This case report describes a 50-year-old man, dying from histologically confirmed, diffuse, malignant mesothelioma after asbestos exposure. As a young man, he had been exposed at the workplace to crocidolite for 2 years, but he had no other known history of occupational or environmental asbestos exposure. The patient presented with chest pain and general weakness. Computed tomography showed bilateral irregular pleural thickening along both lower lateral chest walls and a low attenuating mass in the anterior portion of the left lobe. Pathological examinations revealed that it was an epithelial type with tubulopapillary structures and it tested immunohistochemically positive for antibodies against cytokeratin, calretinin and vimentin. The patient was started on chemotherapy but he died to the disease at ten months after the first onset of the symptoms. Mesothelioma is a rare neoplasm in the general population. Nevertheless, the importance of close medical surveillance of the high-risk population is emphasized, because of increased asbestos exposure.

Dimethylformamide (DMF), a widely used industrial solvent, has been reported to induce subtle to clinically overt hepatotoxicity. Liver injury due to occupational exposure through inhalation and skin contact has been sporadically reported. We report a 23-year-old male who developed intermittent abdominal pain, anorexia, nausea, vomiting, chest discomfort, and general weakness for 4 days after working in a plastic-coated-glove factory. An acute hepatitis episode occurred after working in an enclosed workplace for 3 days. Other causes of hepatitis such as viral, drug induced or alcoholic hepatitis, could be excluded or were considered to be unlikely. Based on occupational history, serological examination and serial liver function examinations, the case was compatible with DMF-induced acute toxic hepatitis. Hepatotoxicity due to occupational exposure to solvents (e.g., DMF) should be considered in any patient with unexplained hepatitis. The fast improvement of the clinical symptoms and the progressive normalization of the liver function tests once the DMF exposure has been stopped, supports the diagnosis.

PURPOSE: The aim of this study was to determine whether crossed cerebellar hyperperfusion (CCH) was helpful in discriminating mesial from lateral temporal lobe epilepsy (TLE) and what other factors were related in the development of CCH on ictal brain SPECT. MATERALS AND METHODS: We conducted retrospective analysis in 59 patients with TLE (M:41, F:18; 27.4+/-7.8 years old; mesial TLE: 51, lateral TLE: 8), which was confirmed by invasive EEG and surgical outcome (Engel class I , II). All the patients underwent ictal Tc-99m HMPAO brain SPECT and their injection time from ictal EEG onset on video EEG monitoring ranged from 11 sec to 75 sec (32.6+/-19.5 sec) in 39 patients. Multiple factors including age, TLE subtype (mesial TLE or lateral TLE), propagation pattern (hyperperfusion localized to temporal lobes, spread to adjacent lobes or contralateral hemisphere) and injection time were evaluated for their relationship with CCH using multiple logistic regression analysis RESULTS: CCH was observed in 18 among 59 patients. CCH developed in 29% (15/51) of mesial TLE patients and 38% (3/8) of lateral TLE patients. CCH was associated with propagation pattern; no CCH (0/13) in patients with hyperperfusion localized to temporal lobe, 30% (7/23) in patients with propagation to adjacent lobes, 48% (11/23) to contralateral hemisphere. Multiple logistic regression analysis revealed that propagation pattern (p=0.01) and age (p=0.02) were related to the development of CCH. CONCLUSION: Crossed cerebellar hyperperfusio ictal brain SPECT did not help differentiate mesial from lateral temporal lobe epilepsy. Crossed cerebellar hyperperfusion was associated with propagation pattern of temporal lobe epilepsy and age.

Plasma cell neoplasms of the liver include primary extramedullary plasmacytoma and a local manifestation of multiple myeloma. Extramedullary plasmacytoma of the liver in multiple myeloma is extremely rare although extramedullary involvement frequently occur in extramedullary sites such as lymph nodes, lung, pleura, gastrointestinal tracts, nervous system and spleen. We experienced a case of multiple myeloma with multiple intrahepatic extramedullary plasmacytomas which initially presented as metastatic cancer of the liver. Intrahepatic extramedullary plasmacytoma confirmed by ultrasono-guided liver biopsy, which disclosed numerous neoplastic plasma cell infiltration.

BACKGROUND: Acute myelod leukemia (AML) is a hematologic malignant disease characterized by uncontrolled proliferation of myeloid cells in marrow and arrest in their maturation. It accounts for 70~80% of chromosomal abnormalities and t (8;21) has been found in 40% of AML-M2. Because cytogenetic studies can help classifying the disease, providing the clues of disease progression and monitoring remission after chemotherapy, we have performed cytogenetic studies to identify the incidence of t (8;21) and other chromosomal abnormalities and to assure their prognostic significance in patients with AML-M2. METHODS: From August 1998 to July 2000, 38 patients with AML-M2 were treated with ara-C and idarubicin in order to induce complete remission. We evaluated chromosomal abnormalities by high resolution banding technique. We divided patients into 3 groups. Patients having normal and intermediate risk karyotype belonged to group A, t (8;21) to group B and, unfavorable and undetermined prognostic karyotype to group C. RESULTS: The incidence of chromosomal abnormalities was 71% (27/38), and the proportion of A, B, and C group were 40%, 30% and 30%, respectively. The median follow up duration of evaluable patients was 381 (55~1,295) days. The complete remission (CR) rate accounted for 79% (30/38). The CR rate in A, B and C group were 88% (14/16), 91% (10/ 11) and 55% (6/11), respectively (P=0.06). The median remission duration had not been reached yet. The median remission duration of group A and B had not been reached yet, but that of group C was 337 days (P=0.60). The overall median survival duration was 567 days, and the median survival duration of group B had not been reached yet, otherwise those that of group A and C were 432 days and 364 days, respectively (P=0.02). CONCLUSION: The incidence of chromosomal abnormalities was observed 71% in patients with AML-M2. The patients with t (8;21) showed higher complete remission rate and tendency to have longer remission duration and survival duration.

Pulmonary lobar transplantation provides a clue to the acute donor shortage. To examine the experimental and clinical applicability of lobar transplantation, the authors observed the extent of lung expansion and infiltrate in the allografted lobe through the sequential analysis of the early chest roentgenograms. MATERIALS AND METHODS: Twenty two mongrel dogs weighting 17 kg on average were used. Donor lung bloc was taken and flushed with Euro-Collins solution. The left lower lobar bloc was procured and implanted in the pneumonectomized recipient dog. The anastomosis was performed in the order of the pulmonary vein, artery, and bronchus. To assess the radiological pattern in the lobar allograft, a grading system was designed according to the extent of lung expansion and infiltrate. RESULTS: A) Expansion pattern: Good to excellent lung expansion was seen on postoperative day 0 in 6 out of 10 dogs; on day 1, 4/7; day 2, 3/12; day 3, 1/1; and day 4, 1/3, respectively. Radiographs on day 6, 7, and 12 also showed good expansion in one dog. B) Lung opacity pattern: Clear to minimal infiltrates were seen on day 0 in 8 out of 10 dogs; day 1, 7/17; day 2, 2/12; and day 4, 1/3. The same appearances were detected in a single dog on day 6, 7, and 12. C) Expansion-opacity correlation pattern: Radiographs on postoperative day 0 showed good expansion with mild infiltrates, and excellent expansion with minimal infiltrates were observed on day 1 in 3 out of 17 dogs, day 2, 1/12; and day 4, 1/3, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

PURPOSE: To assess the role of percutaneous cholecystostomy as a therapeutic maneuver in patients critically ill with acute cholecystitis in community hospitals. MATERIALS AND METHODS: Eighteen patients, 11 with suspected acute calculous cholecystits and seven with acute acalculous cholecystitis underwent emergency percutaneous cholecystostomy. All demonstrated a variety of high risk factors for cholecystectomy: liver cirrhosis (n=2), diabetes mellitus (n=3), cardiac disease (n=3), underlying malignancy (n=2), pulmonary dysfunction (n=1), septic cholangitis (n=5), and old age (n=2). All percutaneous cholecystostomies were performed with ultrasound guidance and preferably using the transhepatic route. RESULTS: All procedures but one were successful, and most cholecystostomies were performed within 5-20 minutes. Technical problems were as follows: guide-wire buckling during catheter insertion (n=2) and procedure failure (n=1). The only major problem was a case of localized bile peritonitis due to procedural failure, but a few minor complications were encountered: catheter dislodgment (n=3), and significant abdominal pain during the procedure (2). After successful cholecystostomy, a dramatic improvement in clinical condition was observed in 16 of 17 patients (94%) within 48 hours. Ten of 16 patients who responded to percutaneous cholecystostomy underwent elective cholecystectomy after the improvement of clinical symptoms, and the remaining six patients improved without other gallbladder interventions. CONCLUSION: Percutaneous cholecystostomy is not only an effective procedure for acute cholecystitis, but also has a definite role in the management of these high-risk patients in community hospitals.

BACKGROUND: With the progress of limited surgery and endoscopic treatment for early gastric cancer (EGC), multiple synchronous EGCs, a cause of recurrence, become more important. The objective of this study was to elucidate the characteristics of multiple synchronous EGCs with an emphasis on features of preoperatively undiagnosed lesions. METHODS: We retrospectively reviewed medical records of 496 patients who underwent a gastrectomy for EGC at our institution between January 2004 and December 2004. RESULTS: Twenty-four patients (4.8%) had multiple synchronous EGCs with 24 main and 27 accessory lesions. Multiple synchronous EGCs showed male predominance (p=0.03). Other characteristics including lymph node metastasis were the same as with single EGC. Out of 27 accessory lesions, six lesions (22%) were not detected preoperatively in six patients (25%). Macroscopically five lesions were flat and one lesion was depressed. Five lesions were located at the anterior or posterior wall of the middle and low third portion and one lesion was located at the lesser curvature side of the upper third portion of the stomach. Two lesions were 4 mm, one lesion was 8 mm, two lesions were 12 mm and one lesion was 15 mm in size (mean diameter = 9.1 mm). Histologically, four lesions were of the differentiated type and two lesions were of the undifferentiated type. CONCLUSIONS: Multiple synchronous EGCs have same clinicopathologic features as a single EGC except for male predominance. Considering the possibility of a synchronous lesion, one should examine the entire stomach precisely with special attention to the anterior, posterior wall and lesser curvature side of the same or neighboring area of a known EGC lesion before treatment.

An assessment of early graft function in canine single lung transplant recipients was made by analysing early postoperative radiographic progression, lung perfusion, bronchial patency and bronchial anastomotic wound healing and histopathology of the allografted lung. Eighteen mongrel dogs weighing 15kg on average were used. Donor lung bloc with a generous atrial cuff, the pulmonary artery and left bronchus were taken and flushed with Euro-Collins solution which implanted in the pneumonectomized recipient dog. Anastomosis was done with the atrium, pulmonary artery and bronchus in that order. To assess an early graft function, a protocol for a grading system was designed into the chest roentgenogram, lung perfusion scan, bronchial patency and histopathologic progression of the bronchial anastomosis and allografted lung (Table 1). The results were obtained as follows: Radiographically, clear to infiltrate was seen in 67% (8/12), 33% (5/15), 30% (3/10) and 33% (2/6) on postoperative day 0, 1, 2 and 3 respectively. Lobar to total opacification was 33% (4/12), 67% (10/15), 70% (7/10) and 67% (4/6) on days 0 to 3 (Table 2). Perfusion scan showed normal to mild defect in 43% (3/7) and moderate to severe defect in 57% (4/7) on day 0 and 100% (5/5) on day 2 (Table 3). The bronchial anastomotic site showed patent to mild stenosis in 100% (8/8) on day 0 and mild stenosis in 2/2 on day 9 bronchofiberscopically, and showed normal wound healing in 38% (3/8), cellular infiltration in 38% (3/8) and infarction in 25% (2/8) up to day 9 postoperatively.(ABSTRACT TRUNCATED AT 250 WORDS)
