RESUMO

BACKGROUND: International guidelines on clinical staging of gastric cancer recommend the use of chest CT for the detection of pulmonary metastases. This study assessed the clinical value of routine chest CT in the staging of gastric cancer. METHODS: This retrospective study included patients identified from the gastric cancer registry of Chang Gung Memorial Hospital, Linkou, Taiwan. All patients who underwent clinical staging between 2008 and 2014 were included. The pattern, site and number of metastases at initial presentation and after surgery with curative intent were evaluated. Pulmonary metastases were defined as multiple small round pulmonary nodules with a random distribution or of variable size. RESULTS: Some 1669 patients were included, of whom 478 (28·6 per cent) had metastatic disease at clinical presentation. The majority of metastases were to the peritoneum (75·7 per cent of patients) or liver (30·5 per cent), and only 27 patients (5·6 per cent) had pulmonary metastases at presentation, none of which were isolated to the lung. Of these 27 patients, 11 had primary lesions located at the cardia/fundus. In 19 patients the lung metastases were also detected on the staging chest X-ray. After surgery there were 196 cancer recurrences. Some 15 patients (7·6 per cent) had lung metastasis and this was not the only site of metastases in any patient. The prevalence of lung metastasis at presentation of the disease and after surgery was 1·6 and 1·5 per cent respectively. CONCLUSION: This study does not support the routine use of chest CT for staging of gastric cancer as isolated pulmonary metastasis in the absence of other metastatic sites could not be detected.

RESUMO

BACKGROUND: Obesity is associated with gut microbiota dysbiosis, disrupted intestinal barrier and chronic inflammation. Given the high and increasing prevalence of obesity worldwide, anti-obesity treatments that are safe, effective and widely available would be beneficial. We examined whether the medicinal mushroom Antrodia cinnamomea may reduce obesity in mice fed with a high-fat diet (HFD). METHODS: Male C57BL/6J mice were fed a HFD for 8 weeks to induce obesity and chronic inflammation. The mice were treated with a water extract of A. cinnamomea (WEAC), and body weight, fat accumulation, inflammation markers, insulin sensitivity and the gut microbiota were monitored. RESULTS: After 8 weeks, the mean body weight of HFD-fed mice was 39.8±1.2 g compared with 35.8±1.3 g for the HFD+1% WEAC group, corresponding to a reduction of 4 g or 10% of body weight (P<0.0001). WEAC supplementation reduced fat accumulation and serum triglycerides in a statistically significant manner in HFD-fed mice. WEAC also reversed the effects of HFD on inflammation markers (interleukin-1ß, interleukin-6, tumor necrosis factor-α), insulin resistance and adipokine production (leptin and adiponectin). Notably, WEAC increased the expression of intestinal tight junctions (zonula occludens-1 and occludin) and antimicrobial proteins (Reg3g and lysozyme C) in the small intestine, leading to reduced blood endotoxemia. Finally, WEAC modulated the composition of the gut microbiota, reducing the Firmicutes/Bacteroidetes ratio and increasing the level of Akkermansia muciniphila and other bacterial species associated with anti-inflammatory properties. CONCLUSIONS: Supplementation with A. cinnamomea produces anti-obesogenic, anti-inflammatory and antidiabetic effects in HFD-fed mice by maintaining intestinal integrity and modulating the gut microbiota.

RESUMO

OBJECTIVES: To investigate whether patients with spinal cord injury (SCI) are at an increased risk of developing Parkinson's disease (PD). STUDY DESIGN: A population-based, propensity score-matched, longitudinal follow-up cohort study. SETTING: The study was conducted using the National Health Insurance (NHI) Research Database. METHODS: A total of 10 125 patients with at least 2 ambulatory visits with a diagnosis of SCI in 2001 were enrolled in the SCI group. The non-SCI group comprised 10 125 propensity score-matched patients without SCI. The propensity scores were computed using a logistic regression model that included age, sex, comorbidities and socioeconomic status. The PD-free survival rates of the two groups were estimated using the Kaplan-Meier method. Stratified Cox proportional hazard regression was used to estimate the effect of SCI on subsequent occurrence of PD. RESULTS: During the 3-year follow-up period, 99 subjects in the SCI group and 59 in the non-SCI group developed PD. The hazard ratio of PD for the SCI group compared with the non-SCI group was 1.65 (95% confidence interval 1.16-2.33, P=0.0049). The PD-free survival rate for the SCI group was lower than that for the non-SCI group (P=0.0017). CONCLUSIONS: This study shows that SCI is associated with a subsequent increased risk of PD. Further studies are needed to elucidate the mechanism underlying this association.

RESUMO

Hepatitis C virus (HCV) core has a pleiotropic effect on various promoters. In this study, we found that the expression of nucleolar phosphoprotein B23 was enhanced in HCV core-expressing cells and, moreover, HCV core interacts directly with the C-terminal end of B23. Using sucrose gradient centrifugation analysis and immunoprecipitation assays, HCV core was found in a large complex containing B23 and its interacting partner transcription factor YY1. Both B23 and HCV core associated with YY1 in the central GA/GK-rich and C-terminal zinc finger domain. These physical interactions between core, B23, and YY1 led to ternary complex formation that was bound to the YY1 response element. In a transient cotransfection experiment, relief of the trans-suppression activity of YY1 on the YY1-response element-driven reporter by core and B23 was found. This is also true when examining the effects of these three constructs on the B23 promoter-driven reporter. Additionally, chromatin immunoprecipitation assays indicated that a transcriptional activation complex consisting of core, together with B23, p300, and YY1, was recruited to the YY1 response element of B23 promoter, and this probably occurred through complex formation between core and these three cellular transcription regulators. This is different from the situation in the absence of core, where YY1 and histone deacetylase 1, but not B23 and p300, were associated on the YY1 element as the transcription repression complex. Together, our results indicate that HCV core can recruit B23 and p300 to relieve the repression effect of YY1 on B23 promoter activity, a property that requires the intrinsic histone acetyltransferase activity of p300. Thus, because these three core-associated cellular transcription regulators have a multitude of cellular interacting proteins and are involved in a versatility of cellular processes, the complex formation described here may partially account for the pleiotropic effects of core protein on gene expression and cellular function in HCV-infected cells.

RESUMO

INTRODUCTION: Information on primary small intestinal lymphoma is more limited than for gastric lymphoma because most of the previous studies did not focus on the former. Few prognostic indicators in primary intestinal lymphoma have been reliably established because of limited patient numbers and variations in criteria for patient selection. In this study, we retrospectively reviewed the clinical and pathological characteristics of small intestinal lymphoma cases from our hospital, to determine prognostic factors and to clarify the effect of surgical resection on prognosis. METHODS: Eighty-two patients were enrolled in this retrospective study between January 1997 and December 2012. Patients were divided into two groups based on whether or not they underwent surgical management. Gross resection was defined as complete removal of the primary lesion(s), as confirmed by the naked eye. Combined therapy refers to concurrent surgery and chemotherapy. The clinicopathological characteristics and long-term outcomes of patients were analyzed and compared between the two groups. RESULTS: Most of the patients had abdominal pain (75.6%), and some had loss of body weight (29.3%) and bowel perforation (22.0%). Sixty-two patients (75.6%) underwent surgical management. Patients in the surgery group presented with fewer B symptoms (fever, night sweats, and weight loss; P = 0.035) but more bulky disease (P = 0.009). The ileocecal region was the most common site of solitary involvement (34.1%). The most common reason for surgery was for tumor-related complications (61.3%). Seven patients (11.3%) developed major complications of surgery, but these were not related to the indication, timing, or type of surgery. Only major surgical complications were statistically significant in relation to early mortality (P = 0.004). The estimated 5-year progression-free survival (PFS) was 35.1% and 5-year overall survival (OS) was 43.2%. Univariate analysis revealed that patients in the surgery group had improved 5-year PFS (P = 0.028). T-cell lymphoma, involvement of multiple gastrointestinal regions and extranodal involvement, higher scores for International Prognostic Index (IPI), more advanced Ann Arbor stage, lactate dehydrogenase (LDH) levels above 215 U/L, and management without combined therapy were prognostic for shorter PFS and OS in univariate analyses. Individuals who received R0 resection or gross resection had improved 5-year PFS and OS. Cox regression analysis demonstrated that primary T-cell lymphoma was an independent negative prognostic factor for both OS and PFS. CONCLUSION: Combined therapy is an independent prognostic factor for long-term survival in small intestinal lymphoma. Gross resection is recommended in patients with small intestinal lymphoma and leads to improved PFS without significantly increasing the risk of complications. Emergency surgery does not lead to poor prognosis. However, caution is warranted in the management of all patients, because of the high risk of post-operative complications and potential for early mortality.

RESUMO

BACKGROUND: The role of laparoscopic surgery for malignant gallbladder tumors remains uncertain. This study compared the surgical results of laparoscopic versus conventional open cholecystectomy for patients with early-stage gallbladder carcinoma and examined the role of laparoscopic surgery for early gallbladder carcinomas. METHODS: Data for the treatment of gallbladder carcinomas were gathered from Chang Gung Memorial Hospital (Linkou, Taiwan). A retrospective analysis of 40 patients with either stage 0 or stage 1 gallbladder carcinoma was performed. The patients were categorized into two groups on the basis of cholecystectomy procedures. The long-term outcomes for the two groups were compared. RESULTS: During the follow-up period, which ranged from 6.5 to 197.6 months, four patients in the conventional open cholecystectomy group encountered tumor recurrence, and one patient in the laparoscopic cholecystectomy group experienced distant tumor recurrence (p = 0.216). No local port-site tumor recurrence was identified in patients who underwent laparoscopic cholecystectomy. The overall 5-year survival rate in this series was 87.1%. A comparison of survival rates between the two groups demonstrated no significant difference (p = 0.340). CONCLUSION: The laparoscopic cholecystectomy procedure did not adversely influence the prognosis of patients with early-stage gallbladder carcinomas. Furthermore, meticulous removal of gallbladders during laparoscopic surgery, in which early gallbladder carcinoma can be managed successfully using laparoscopic cholecystectomy, achieved a satisfactory surgical result and a low port-site tumor recurrence rate.

RESUMO

All admissions to a 16-bed multidisciplinary pediatric intensive care unit (PICU) were evaluated during two time periods totaling 13.5 months. Daily evaluations of therapeutic and monitoring care modalities were accomplished with the Therapeutic Intervention Scoring System (TISS) and daily assessments of severity of illness were done by using the Physiologic Stability Index. Of the 822 patients included in this study, 226 (27.5%) never received a therapy that could only be given in the PICU. These patients were known as the monitoring group and used 7.5% (297/3,969) of the bed days. The percentage of Therapeutic Intervention Scoring System points used by the monitoring patients was 3.6% (3,575/100,109). All patients who were monitored survived; 213 (94.2%) were classified as low mortality risk based on their level of physiologic stability. These data indicate that a significant percentage of PICU patients never receive a therapy that requires the PICU but only receive monitoring and routine care techniques. Significant reductions in PICU use could occur with more efficient usage.

RESUMO

Anticardiolipin (ACL) antibodies and interleukin-6 (IL-6) in cerebrospinal fluid (CSF) may be involved in the mechanism of lupus patients with central nervous system (CNS) involvement. ACL antibodies of 3 isotypes and IL-6 were measured in paired CSF and serum samples from 14 lupus patients with CNS involvement, 5 lupus patients without CNS involvement and 7 patients with non-inflammatory neurological diseases. ACL antibodies, IgG and IgM isotypes, and IL-6 were significantly increased in CSF from lupus patients with CNS involvement as compared with other 2 groups of patients. Both ACL antibodies and IL-6 decreased after neurological activity subsided. These results suggest increased ACL antibodies and IL-6 in CSF are involved in immune responses within CNS in lupus patients. Quantitation of CSF ACL antibodies may be helpful in evaluating neurological activity of lupus patients with CNS involvement.

RESUMO

Previously, we reported that the LMP 1 gene of Epstein-Barr virus (EBV) derived from nasopharyngeal carcinoma (NPC) tissues (i.e., NLMP 1 gene) was able to transform BALB/c3T3 cells. On the other hand, LMP 1 gene of B95-8 strain (i.e., BLMP 1 gene) was not able to transform these cells (Chen et aL, 1992). Further studies indicated that a 10-amino-acid deletion in the carboxyl terminus of NLMP 1 played an important role in transformation (Li et al., 1996). In this study, we tested if this 10-amino-acid deletion affected the induction of NF-kappaB activity by LMP 1. The long terminal repeat of the human immunodeficiency virus type 1 (HIV-1 LTR) contained two copies of NF-kappaB sites and was used to construct the Luc gene-based reporter plasmid, p kappaB-Luc. Plasmid p kappaB-Luc was co-transfected with plasmids containing the NLMP 1 gene, BLMP 1 gene, and their chimeric or deletion constructs, respectively, into C-33A and BALB/c3T3 cells. The activation was then measured by the luciferase activity. Results showed that the full-length proteins induced a similar level of NF-kappaB activity, the two 3' mutants (R15delta and D4delta) still induced a relatively high level of activity, and the two 5' deletion mutants (delta3058 and delta3243) of NLMP 1 gene did not show any significant activation in C-33A cells. However, none of these LMP 1 proteins induced NF-kappaB activity in BALB/c3T3 cells. Using subcellular fractionation analysis and an immunocytostaining method, the truncated proteins of delta3058 and delta3243 were detected in the cytoplasm of the cells whereas the full-length NLMP 1 protein was located at the cytoplasmic membrane. Stable BALB/c3T3 cell clones that expressed both truncated proteins were established and then their ability to induce tumors in nude mice was examined. Data showed that both truncated NLMP 1 proteins still maintained partial transformation activity. Our results suggested that there was no direct correlation between NF-kappaB activation and transformation activity of LMP 1 in BALB/c3T3 cell transformation and that the amino-terminal membrane-spanning domain was important for maintaining both functions of LMP 1.

RESUMO

HYPOTHESIS: Dedifferentiation of human hepatocellular carcinoma (HCC) may influence telomerase activation and Ki-67 expression. DESIGN: Laboratory study using human HCC specimens. SETTING: University hospital. PATIENTS: Twelve patients with HCC with specific morphologic patterns (nodule-in-nodule [n = 4] or confluent multinodular [n = 8] type) and histological heterogeneity and who had undergone curative hepatectomy were studied. Of these, 8 patients had 2 different histological grades of HCC cells distributed at various nodules but within the same tumor; 3 patients, 3 different histological grades; and 1 patient, all 4 different histological grades. INTERVENTION: Tissue samples were retrieved from each nodule of the tumor and not mixed with one another. A total of 42 cancerous tissues from different distinctive nodules of the 12 patients were taken for telomerase and Ki-67 study, and corresponding noncancerous counterparts (n = 12) served as healthy control samples. Telomerase activity was assayed by the telomerase repeat amplification protocol. Expression of messenger RNA (mRNA) by the human telomerase catalytic subunit human telomerase reverse transcriptase (hTERT) was determined using reverse transcription polymerase chain reaction. The relative telomerase activity and hTERT mRNA in each tissue sample was quantified using densitometry and expressed as a percentage of the standardized HeLa cell line. Immunostaining with anti-Ki-67 antibody was used to detect Ki-67 and was expressed as Ki-67 labeling index. MAIN OUTCOME MEASURES: Telomerase activity, hTERT mRNA, and Ki-67 labeling index stratified by different histological gradings in each patient was analyzed. The correlations between telomerase activity and hTERT mRNA and between telomerase activity and expression of Ki-67 were plotted. RESULTS: Telomerase activity increased from more to less differentiated foci of HCC cells in each case (generalized linear model, P<.001). Mean +/- SD expression of hTERT mRNA in 43 cancerous tissue samples, even those 4 with negative telomerase activity, was distinguishable from that of the noncancerous controls (0.84 + 0.23 vs 0.41 + 0.11; t test, P =.008). Telomerase activity was correlated to hTERT mRNA expression (Pearson correlation, r(2) = 0.56; P<.001). The Ki-67 labeling index increased from more to less differentiated foci of HCC in each case (generalized linear model, P<.001). Expression of Ki-67 correlated with telomerase activity within differently graded areas within individual tumors (Pearson correlation, r(2) = 0.38; P<. 001). CONCLUSION: Using the model of human HCC with histological heterogeneity, we determined that dedifferentiation of human HCC induces telomerase activation and Ki-67 expression.

RESUMO

BACKGROUND: Prognosis of pyogenic liver abscesses in patients with malignant disease is generally considered poor. The discrepancy between the outcomes of liver abscesses caused by hepatopancreatobiliary malignant disease and those caused by other malignant diseases, however, to our knowledge has never been investigated. OBJECTIVES: To clarify the clinical course of pyogenic liver abscess in patients with different types of cancer, and to compare outcomes in abscesses caused by hepatopancreatobiliary malignant disease and other malignant disease. DESIGN: Retrospective review of case series in our experience from 1980 through 1993. SETTING: Tertiary care university teaching hospital. PATIENTS: Fifty-two patients with pyogenic liver abscess related to the underlying cancer were divided into 2 groups. Group 1 (n=32) was composed of patients with cancer originating from the hepatic parenchyma, bile duct, and pancreas; group 2 (n=20) was composed of patients with cancer originating from other sites. INTERVENTIONS: Parenteral antibiotics, percutaneous drainage, surgical drainage, or hepatectomy, in combinations, were employed. MAIN OUTCOME MEASURES: Patient characteristics, symptoms, laboratory data, abscess characteristics, microbiological study, management, and outcome of the 2 groups were analyzed. RESULTS: Thirteen patients (41%) in group 1 and 16 patients (80%) in group 2 had undergone prior anticancer treatment. Jaundice was encountered more often in group 1 than in group 2 (29 patients [91%] vs 6 patients [30%], respectively, P=.001), whereas nausea and vomiting were more frequently seen in group 2 than in group 1 (17 patients [52%] vs 6 patients[31%], respectively, P=.04). Leukocytosis, hypoalbuminemia, hyperbilirubinemia, and reversed albumin-globulin ratio were more pronounced in group 1 than in group 2 (P=.001, .02, .003, and .03, respectively). Abscesses communicating with the intrahepatic biliary tree were more frequently encountered in group 1 than in group 2 (11 patients [34%] vs 2 patients [10%], respectively, P=.03). Escherichia coli and Klebsiella pneumoniae predominated in group 1, while the bacteria species in group 2 were more diverse. The hospital mortality rates of group 1 and group 2 were 28% (9 of 32 patients) vs 10% (2 of 20 patients) (P=.04), respectively. Twenty-three patients (72%) of group 1 died of uncontrolled biliary sepsis or progressive cancer or both within 6 months after the diagnosis, while 17 patients (85%) of group 2 survived longer than 1 year without relapse of the abscess and continued with anticancer treatment. CONCLUSIONS: Pyogenic liver abscess could be a presentation of hepatopancreatobiliary malignant disease at the preterminal stage, and carries a grave prognosis. Pyogenic liver abscess in patients with nonhepatopancreatobiliary malignant disease has a better chance of favorable outcome.

RESUMO

BACKGROUND: Several experimental and clinical reports concerning endoscopic parathyroid surgery have appeared. However, reports concerning minimally invasive surgery for thyroid remains rare. Herein we present a new method, called video-assisted endoscopic thyroidectomy (VAET), for the management of various benign thyroid diseases. METHODS: In all, 16 consecutive patients who underwent VAET for benign thyroid diseases were retrospectively studied. The study group included nodular hyperplasia in 8 patients, follicular adenoma in 6, and Hurthle's tumor and simple cyst in 1 each. A 2 to 3 cm transverse incision was made on the suprasternal notch. The wound was deepened to expose the underlying trachea from which the plane of the thyroid fascia was accessed directly, and the working space was established with lifting method using conventional instrument. All surgical procedures could be manipulated and monitored under laparoscopy without gas insufflation. The ultrasonically activated scalpel was the principal instrument used for VAET. RESULTS: All 16 patients underwent VAET successfully without conversion to open thyroidectomy. The surgical procedures included lobectomy in 13 and extirpation in 3. The operation time ranged from 28 minutes to 5 hours (mean 1 hour, 42 minutes). For the 5 most recent cases, lobectomy took an average of 2 hours, whereas extirpation less than 40 minutes. The tumor size ranged from 3.5 cm to 8.0 cm (mean 5.8 cm). There were no surgical complications. All patients but 1 were discharged on postoperative day 2. During follow-up, all patients demonstrated euthyroid function and satisfactory cosmetic results. CONCLUSIONS: VAET emerges as a promising minimally invasive surgical technique replacing conventional thyroidectomy for benign thyroid diseases in selected cases, with the advantage of satisfactory cosmetic results.

RESUMO

Intraabdominal lymphangiomas are rare benign tumors that can be difficult to diagnose preoperatively. The clinical presentation of these tumors is variable and potentially misleading. Therefore, complex imaging studies are required to evaluate this condition. Ultrasound and CT scan are important to make the correct preoperative diagnosis and also provide important information regarding location, size, and adjacent organ involvement. The treatment of choice is complete excision. This report describes two patients with cystic lymphangiomas originating in the gallbladder. The correct diagnosis was made preoperatively in one patient, and both patients were treated successfully by laparoscopy.

RESUMO

It is evident that the field of pediatric critical care is evolving rapidly, but the prime issue remains the proper delivery of scarce and expensive resources to the most patients. In order to do so it is necessary to determine where current resources exist. This has been difficult to accomplish accurately on a national basis, although it may be possible on a regional level. To achieve the final goal of building organized systems of care, the special needs of the critically ill and injured child must be recognized. Models of regionalization will provide the basic structure for the development of these systems. The Model for a Pediatric Critical Care System proposed by the California Critical Care Coalition and District IX of the American Academy of Pediatrics should be readily applicable to any region. It is hoped that the information and examples provided in this article will provide some guidelines for those interested in promoting regionalization of pediatric critical care across the nation.

RESUMO

BACKGROUND/AIMS: Gastrointestinal hemorrhages of obscure origin are often difficult to diagnose and manage. Of these, splanchnic artery aneurysms have emerged as an important disorder because of the increasing prevalence and formidable mortality rate associated with their rupture. We herein evaluated extra-enteric gastrointestinal bleeding related to these ruptured aneurysms. METHODOLOGY: The medical records of 17 patients with splanchnic artery aneurysms known to be exclusively manifested as gastrointestinal bleeding were reviewed. The pathogenesis, clinical picture, diagnostic tests, management, complications, and outcomes were compiled and analyzed. RESULTS: Of the seventeen patients, 12 patients had true aneurysms; 5 patients had false aneurysms. Pancreatitis, trauma, iatrogenic hepatobiliary injury, and atherosclerosis were the four major etiologies. The sensitivity rates measured by endoscopy, ultrasonography, computed tomography and visceral angiography were 20%, 50%, 67%, and 100%, respectively. An exact diagnosis was attained in 94% of the patients at the time of management. Transcatheter embolization was employed in 7 patients, complicated with hepatic and splenic infarcts, and pyogenic liver abscesses in 2 instances. Two patients had recurrent bleeding aneurysms post embolotherapy. Ten patients underwent surgical intervention which resulted in 2 cases of hepatic failure. One out of 5 patients with a true aneurysm died, while 4 out of 12 patients with false aneurysms eventually died. Overall, the mortality rate was 29%. CONCLUSION: Even though the exact diagnosis can be made in most of the patients by modern imaging studies, the mortality rate was still formidable, especially in patients with false aneurysms, in whom the underlying causal diseases substantially influenced the major outcome.

RESUMO

A review of 240 consecutive Chinese patients with endogenous uveitis seen over a 3-year period was made in Taiwan. The frequency of major types of uveitis was 110 cases (45.8%) of acute anterior uveitis, 43 cases (17.9%) of Behçet's disease, 22 cases (9.2%) of Harada's disease, 10 cases (4.2%) of peripheral uveitis, 6 cases (2.5%) of virus-induced uveitis and 5 cases (2.1%) of Fuchs' heterochromic cyclitis. Only 1 case (0.4%) of sarcoidosis was found. Of the 110 cases of acute anterior uveitis, 80.9% presented with HLA-B27 antigen. The incidences of types of endogenous uveitis in Chinese differ from those in Caucasians, Japanese and Negro races in the USA.

RESUMO

Neuromuscular manifestations, including a variety of peripheral neuropathies and myopathies, can occur either as isolated clinical phenomena or concurrently with other clinical manifestations, and are common in acquired immunodeficiency syndrome (AIDS). A 33-year-old male patient had a four-year history of increasing proximal muscle weakness of the extremities. Elevated muscle enzymes, a muscle biopsy and interstitial lung disease all suggested a diagnosis of polymyositis with lung involvement. However, a transbronchial lung biopsy revealed Pneumocystis carinii pneumonia, and serology for HIV infection disclosed positive results. Zidovudine and cotrimoxazole were instituted and the patient improved. HIV-associated myopathy should be considered by practicing clinicians in cases presenting with myopathy, since the number of patients with HIV infection is increasing in Taiwan.

RESUMO

A total of 103 cases with ocular involvement of Behcet's disease, seen over a period of 19 years (1970 to 1988), were collected from the ophthalmological departments of 6 major medical centers in Taiwan. The yearly number of patients who first visited these hospitals from 1979 through 1983 was about 5 cases and about 14 cases from 1984 to 1988. The domiciles of the patients were most commonly (51.5%) in Northern Taiwan. All 103 patients were Chinese, of which 78 (75.7%) were men and 25 (24.3%) were women; the male to female ratio was 3.1. Extraocular symptoms of Behçet's disease, major or minor, and their frequencies among these patients included; oral ulcers, 97.1%, skin lesions, 74.8%; genital ulcers, 61.2%; arthritis, 47.6%; gastrointestinal lesions, 14.6%; epididymitis, 5.8%; central nervous system lesions, 2.9%; vascular lesions, 1.9%; pulmonary lesions, 2.9% and urinary lesions, 4.9%. Fifty-one (49.5%) patients were of the complete type and 52 (50.5%) of the incomplete type. The peak distribution of ages at the onset of the ocular lesions, was from 20 to 40 years. As for visual prognosis, 37.9% of the 198 diseases eyes had a visual acuity of 0.5 or better, 9.1% between 0.5 and 0.1, 25.3% between 0.1 and 0.01 and 27.8% were 0.01 or worse. In 24 (12.1%) eyes, the vision was completely lost. In HLA studies, a significantly increased incidence of HLA-A26 (p less than 0.01) and HLA-B51 (p less than 0.001) was found.(ABSTRACT TRUNCATED AT 250 WORDS)

RESUMO

BACKGROUND AND OBJECTIVES: Many series describing the management of major bile duct injuries after laparoscopic cholecystectomy have been reported with satisfactory short-term results. However, the information of their prognosis with sufficient time-period follow-up is sparse. METHODS: Sixteen consecutive patients with major bile duct injury following laparoscopic cholecystectomy were retrospectively reviewed, including six common bile duct transections, four bile duct perforations, and six hilar strictures but without perforation. With respect to the level of bile duct injuries, there were the following based on Bismuth's classification: type 1 in six patients, type 2 in five patients, type 3 in three patients, type 4 in one patient, and type 5 in one patient. All patients received surgical management, interventional radiology and endoscopic treatment. The time periods of follow-up ranged from 37 to 72 months (mean, 52 months). The final results were rated as being excellent, good, fair, or poor, based on the criteria of symptoms, biochemical data, and radiology. RESULTS: There was no procedure-related mortality. Ten of the 16 patients had either excellent or good results, two had fair results, and four had poor results. Of the latter four, the patients had been classified as Bismuth type 1, 3, 4, and 5, respectively, and all sustained a failed initial surgical repair. CONCLUSIONS: Using a multidisciplinary approach, 12 (75%) of the 16 patients attained a promising result through a long-term follow-up, while those with the higher biliary stricture and with an unsuccessful initial surgical repair had a disappointing outcome.

RESUMO

Avermectin B, isazofos, and fenamiphos were evaluated in greenhouse experiments for efficacy against two common turfgrass parasites, Hoplolaimus galeatus and Tylenchorhynchus dubius. Treatments in all experiments were arranged in a completely randomized design and replicated four times. In the first experiment, avermectin B at rates of 0.2 and 0.4 kg a.i./ha and isazofos at rates of 2.3 and 23 kg a.i./ha significantly reduced populations of both species of parasitic nematodes compared to controls at 14 and 28 days after treatment (P
