BACKGROUND: Herpes zoster is a significant and troublesome disease. The pain of acute herpes zoster may be severe, but is usually transitory. Some patients, especially the elderly at particular risk, go on to develop neuralgia. Unfortunately, neuralgia is often severe and refractory to most forms of treatment. The purpose of this study was to estimate improved rates of neuralgia according to associated factors. METHODS: We observed the improved rates of neuralgia in 123 patients who had herpes zoster with severe pain and treated with antiviral therapy after admission. Also, we compared them by age group, dermatomal distribution, and initiating day of antiviral therapy. RESULTS: At 4 weeks of treatment, the improved rates of neuralgia according to age younger group was high and older group was low. The improved rates of neuralgia according to the starting day of treatment was high 100% in 1 day, 76.5% in 2, 65.0% in 3days, and 18.2% in 7 days after skin eruption. CONCLUSION: In herpes zoster with severe pain, age and initiation of antiviral therapy are significant predictors of neuralgia.

The author has investigated the protective effects of systemic Heparin and intrathecal Urokinase in the multi-hemorrhage canine model of severe chronic cerebral vasospasm. Each of 20 adult mongrel dogs was assigned to one of three experimental groups. All animals received a total of 12ml of fresh unheparinized autologous blood via three cisternal injections. Selective vertebral angiograms were obtained before and 8 days after the initial subarachnoid blood injection. Seven animals were treated by systemic Heparin for 7 days, the other seven were treated by intracisternal Urokinase for 3 days, and the remaining were not treated. Comparisons were based on the percentage of reduction in basilar artery diameter(% RBAD). The ultrastructural changes were studied by transmission electron microscopy(TEM). There was a mean reduction(+/-standard deviation) of 65+/-7% in control dogs, 53+/-5% in dogs with systemic Heparin(difference significant t-test, p<0.01), 37+/-6% in dogs with intrathecal Urokinase(difference signignificant, t-test, p<0.01). The preventive effects of intrathecal Urokinase was superior to systemic Heparin. There was a stroung trend toward reduction of medial necrosis in the basilar artery in dogs with intrathecal Urokinase(p<0.01), and with systemic Heparin(0.05 Adult ; Angiography ; Animals ; Arteries ; Basilar Artery ; Dogs ; Heparin* ; Humans ; Muscle, Smooth ; Necrosis ; Urokinase-Type Plasminogen Activator* ; Vasospasm, Intracranial*

Lymphorrhea is a rare but potentially severe complication that occurs after various surgical procedures. Untreated lymphorrhea may lead to wound dehiscence, infection, and prolonged hospital stay. Currently, there is no standard effective treatment. Early management usually includes leg elevation, drainage, and pressure dressing. However, these methods are associated with prolonged recovery and high recurrence rates. We report a case of lymphorrhea from a calf wound after endoscopic great saphenous vein (GSV) harvesting for coronary artery bypass grafting (CABG). The patient presented with intractable oozing from the postoperative wound on the right calf. Lymphorrhea perGsisted for 6 weeks despite negative-pressure wound therapy with a long-acting somatostatin. We performed unilateral pedal lymphangiography that confirmed wound lymphorrhea, followed by glue embolization. No recurrence was observed after 8 months of follow-up. This case report demonstrates the successful use of lymphangiography with glue embolization in the control of lymphorrhea after GSV harvesting for CABG.

PURPOSE: We aimed to assess retrospectively the benefit of the use of ultrasonography (US) in comparison with the use of only CT imaging for the detection of the transition zone and adhesions to determine a diagnosis of adhesive small-bowel obstruction (SBO). MATERIALS AND METHODS: Thirty-five patients underwent an additional US examination after CT imaging to determine a diagnosis of SBO. All of the patients were surgically confirmed as having adhesive SBO. The CT images were interpreted for the location of the transition zone, the location and shape of adhesions and for other SBO findings. All of the additional US scans were performed with reference to the CT findings. The standard of reference for the diagnosis was the surgical findings. The diagnostic accuracy and mean confidence score of the transition zone location and the detection rate of adhesions were evaluated for both CT imaging alone and for CT imaging with additional US. RESULTS: The diagnostic accuracy to locate the transition zone was significantly increased with the use of additional US with CT imaging (94.6%, 33/35) as compared to 65.7% (23/35) with the use of only CT imaging (p = 0.01). The mean confidence score was significantly increased (by 0.95) with the use of an additional US examination (p < 0.01). The detection rate for adhesions was 20% (7/35) with the use of only CT imaging and the detection rate was 68.6% (24/35) with the use of an additional US examination. CONCLUSION: The use of a US examination in addition to CT imaging can increase the accuracy and confidence to locate the transition zone and can increase the rate to detect adhesions in patients with adhesive SBO. An additional US examination may be especially helpful when the CT findings are equivocal.

BACKGROUND: The survival benefit of combination chemotherapy comparing supportive care to patients with advanced non-small cell lung cancer, especially stage IV non-small cell lung cancer patients with metastatic disease, is controversial. The main goal of this study was to evaluate the difference in survival between patients treated with chemotherapy and those who were not and to identify prognostic factors in the patients with stage IV non-small cell lung cancer. METHODS: From January 1989 to December 1994, total 67 patients including 20 patients treated with combination chemotherapy and 47 patients treated with only supportive care in stage IV non-small cell lung cancer patients with metastatic disease were enrolled in this study. Combination chemotherapy consisted of etoposide 120mg/m2 iv for 3 days and cis-platin iv day 1 every 4 weeks. The treatment groups were retrospectively analyzed by age, sex, histologic cell type, weight loss, serum LDH level, ECOG performance status and major organ metastasis. RESULTS: The significant prognostic factors influencing survival on this study were ECOG performance status and histologic subtype. Overall response rate by combination chemo-therapy was 30%(complete response 0%, partial response 30%). Median survival of overall patients was 13.6 weeks and median survival of chemotherapy group, 20 weeks, was significantly longer than that of supportive care group, 11.7 week(p<0.01). Median survival of responder in patients receiving chemotherapy, 45.5 weeks, was significantly longer than that of non-responder, 17.3 weeks(p<0.05). 1 year-survival rate of chemotherapy group and supportive care group was 15% and 8%, respectively. Nausea or vomiting, alopecia and anemia were seen in nearly most cases after this combination chemotherapy. Toxicities above grade 3 included neutropenia, anemia, thrombocytopenia, infection, fever, nausea, vomiting and alopecia. But this combination chemotherapy was relatively well tolerated except one treatment-related death from sepsis associated with severe granulocytopenia. CONCLUSION: These results suggest that systemic chemotherapy might be helpful to the stage IV non-small cell lung cancer patients with good performance status and large scale randomized prospective trials should be performed.

PURPOSE: This study was performed to evaluate factors that can predict the presence of a malignancy for localized intrahepatic bile duct dilatation without a visible mass or stone as depicted on CT images. MATERIALS AND METHODS: A total of 29 patients (male: 16, female: 13) who had localized intrahepatic bile duct dilatation without a visible mass, stone or injury as depicted on CT images were included in the study. A history of extrahepatic malignancy and biliary stone disease, tumor marker levels, CT findings of the intrahepatic bile duct and associated findings were reviewed. The findings were analyzed between two groups (patients with a malignancy and patients with benign disease) on follow-up. RESULTS: In 29 patients, 11 patients had malignant lesions (four metastases and seven cholangiocarcinomas). The history of an extrahepatic malignancy and the shape of an intrahepatic duct obstruction or stenosis as seen on CT were significantly correlated with the results between the benign and malignant group of patients. The follow-up results of the malignant group of patients indicated that for six patients who had developed a new mass, one patient each showed aggravation of ductal dilatation and thickening of the ductal wall. CONCLUSION: When a patient with localized intrahepatic bile duct dilatation without a definite cause has a history of an extrahepatic malignancy or shows abrupt tapering or irregular narrowing on CT images, short-term follow-up should be performed. The patient should be investigated carefully for mass formation or a change of the dilated bile duct due to a possibility of malignant ductal dilatation.

Spinal Cord contusions in cats were produced experimentally by impact injuries to the surgically exposed cord at the second lumbar vertebral level. As a step in the investigation of the possible effect of spinal cord trauma on biochemical and ultrastructural changes in the injured cord, activities of lipid peroxidation were measured in the frozen-dried sample of the spinal cord and the fine structure of the myelinated nerve fiber in the white matter were observed before and after the cord injury. An increase of lipid peroxidation level was found as early as 30 minutes after the injury and the highest concentration was reached at 4 hours of injury. Fine structures of the myelinated nerve fibers were changed progressively with the lapse of time after the injury. By 1 hour after the contusion the myelinated nerve fibers showed moderately enlarged periaxonal space, attenuation and disarray of the myelin sheaths. By 4 hour after the contusion, there appeared disarray of the myelin sheaths, greatly enlarged periaxonal space and irregulary contoured axons. The effect of naloxone of the lipid peroxidation and fine ultrastructure of the myelinated nerve fibers were studied, and the results of this study suggested that naloxone have a beneficial effect on the change in lipid peroxidation and the preservation of the myelinated nerve fibers after injury.

Patterns of brain-stem compression and secondary brain-stem evoked postentials were investigated to correlate with expanding mass volume and location in mass-induced supratentorial brain compression in cats in which the subjects were divided into four experimental group i.e., frontal, temporal, parietal, and occipital brain-compressed groups. Postmortem insepection of the brain-stem showed either unilateral or bilateral dorsal herniation of the brain in frontal and temporal brain-compressed groups and dorsolateral herniation in parietal and occipital brain-compressed groups, respectively. Microscopic examination revealed that the secondary brain-stem hemorrhages were mostly caused by venous bleeding secondary to venous congestion, the bleeding being more severe in occipital brain-compressed group. As the intracranial pressure was raised by expansion of a supratentorial balloon, the late components of the BSEP were suppressed first, followed by the suppression of the early components. In BSEP recording a significant change was observed in Vth wave with prolongation of latency and decrease in amplitude. This finding suggests that the midbrain is the most vulnerable to compression ischemia. In parietal group, the Vth wave started to be prolonged at 0.4ml of balloon expansion and totally disappeared at 1.8ml of expansion.

PURPOSE: To assess the usefulness of an ultrasound (US)-guided peritoneal biopsy for the solitary peritoneal thickening visualized as only infiltrated fat on a computed tomography (CT) scan. MATERIALS AND METHODS: This retrospective study included 36 patients (16 males, 20 females; mean age, 51.7 years) who underwent a US-guided biopsy for the solitary peritoneal thickening of unknown cause visualized as only infiltrated fat without an apparent mass formation on a CT scan. The rate of the specific histopathological diagnosis and accuracy for the diagnosis of malignant disease was assessed. RESULTS: The procedure was technically successful with the acquisition of an adequate amount of the specimen for microscopic examination from all patients. A specific histopathological diagnosis was made in 31/36 patients (86.1%): peritoneal carcinomatosis in 15/31 (48.4%), tuberculous peritonitis in 15/31 (48.4%) and panniculitis in 1/31 (3.2%). A non-specific histopathological diagnosis was made in 5/36 (13.9%): chronic inflammation in 4/5 (80%) and mesothelial hyperplasia in 1/5 (20%). The procedure showed sensitivity of 83.3%, with a specificity of 100%, a positive predictive value of 100%, a negative predictive value of 85.7%, and an accuracy rate of 86.1% for the diagnosis of malignant diseases. CONCLUSION The US-guided peritoneal biopsy is a fairly accurate diagnostic procedure for the peritoneal thickening visualized as only infiltrated fat on a CT scan, and it can be used before performing laparoscopic or an open biopsy.

PURPOSE: To find out the differences in eating habits between poor feeding and non-poor feeding children. METHODS: We performed questionnaires on 504 children under four years of age who visited hospitals in Gwangju city and JaollaNamdo from May to August, 2002. RESULTS: 138 (27.4%) children were included in poor feeding group, and 366 (72.%) children were in non-poor feeding group. Breast feeding rate was 18.8% in the poor feeding group and 20.3% in the non-poor feeding group. Duration of breast feeding for less than six months were noted in 70.5% of poor feeding group, and 58.5% of non-poor feeding group. The time at starting solid food in the poor feeding group was as follows; 15.9% of infants started on solid food when they were 2~4 months old, 32.7% during 4~6 months, 38.1% during 6~8 months and 18.8% over one year of age. Solid food was given in wrongly manners in both groups by nursing bottles, including 80.4% in poor feeding group and 66.6% in non-poor feeding group. CONCLUSION: This study demonstrated close relationships among poor feeding children under four years of age with history of low rate and short duration of breast feeding, inappropriate time to start on solid food, less interest in food during mealtime, and unbalanced diet. Pediatricians should make an effort to play an important role in nutritional education and treatment in children.
