Association between serum inflammatory cytokines and disease activity in juvenile idiopathic arthritis.

Circulating interleukin-1beta (IL-1beta), IL-6, tumour necrosis factor-alpha (TNF-alpha), osteocalcin, and conventional parameters of inflammation were examined serially in 14 children with juvenile idiopathic arthritis (JIA) to determine any correlation with the disease activity. Serum IL-1beta was undetectable in all JIA patients. Serum IL-6, white blood cell counts, platelet counts, erythrocyte sedimentation rate and C-reactive protein levels were significantly elevated in the active phase of JIA, whereas hemoglobin levels were significantly lower. Osteocalcin levels were decreased and TNF-alpha increased in active JIA status, but these differences showed no statistical significance. We concluded that inflammatory cytokines play an important role in JIA. Monitoring IL-6 in children with JIA is useful in determining disease activity and response to therapy. These findings confirm earlier reports.

Environmental risk factors of young onset Parkinson's disease: a case-control study.

While the cause of Parkinson's disease (PD) remains unknown, recent evidence suggests certain environmental factors, such as well water drinking, herbicides and pesticides exposure, and neurotoxins, may trigger the chain of oxidative reactions culminating in the death of dopaminergic neurons in substantia nigra to cause parkinsonism. Most studies to date focused on PD with old age onset. However, there is a peculiar group of parkinsonian patients, the young onset Parkinson's disease (YOPD), in whom the age of onset is before 40. It is intriguing to know whether earlier exposure to the putative neurotoxin(s) may contribute to the earlier onset. We therefore conducted this case-control study in which 60 PD patients, 30 YOPD patients and the same number of age- and sex-matched young controls were included. Using logistic regression, we found well water drinking and head injury were risk factors for the development of YOPD. When YOPD patients were compared with PD, we found head injury and exercise were the significant predictors. Keeping all other variables constant, head injury was a risk factor and exercise appeared to be a protective factor. We conclude early exposure to well water drinking and head trauma may trigger and expedite the appearance of parkinsonian features, but such acceleration may be prevented through regular exercise.

Risk factors for pneumothorax and bleeding after CT-guided percutaneous coaxial cutting needle biopsy of lung lesions.

PURPOSE: To evaluate risk factors for pneumothorax and bleeding after computed tomography (CT)-guided percutaneous coaxial cutting needle biopsy of lung lesions. MATERIALS AND METHODS: This study involved 117 consecutive patients with 117 intrapulmonary lesions. Statistical analysis of factors related to patient characteristics, lung lesions, and biopsy technique was performed to determine possible contribution to the occurrence of pneumothorax and bleeding. Interactions between related factors were considered to prevent colinearity. RESULTS: Pneumothorax occurred in 12% (14 of 117) of patients. Needle aspiration of two moderate asymptomatic pneumothoraces were performed; there was no chest tube insertion. Lesion depth (P =.0097), measured from the pleural puncture site to the edge of the intrapulmonary lesion along the needle path, was the single significant predictor of pneumothorax. The highest risk of pneumothorax occurred in subpleural lesions 2 cm or shorter in depth (this represented 33% of lung lesions but caused 71% of all pneumothoraces; OR = 7.1; 95% CI, 1.3-50.8). Bleeding presented as lung parenchyma hemorrhage and hemoptysis in 30 patients (26%). Hemoptysis occurred in four patients (3%). Univariate analysis identified lesion depth (P <.0001), lesion size (P <.015), and pathology type (P =.007) as risk factors for bleeding. Multivariate logistic regression analysis identified lesion depth as the most important risk factor, with the highest bleeding risk for lesions more than 2 cm deep (14% of lesions caused 46% of all bleeding; OR = 17.3; 95% CI, 3.3-121.4). CONCLUSIONS: In CT-guided coaxial cutting needle biopsy, lesion depth is the single predictor for risk of pneumothorax, which occurs at the highest rate in subpleural lesions. Increased risk of bleeding occurs in lesions deeper than 2 cm.

Air enema for diagnosis and reduction of intussusception in children: clinical experience and fluoroscopy time correlation.

PURPOSE: The objective of this study was to correlate the fluoroscopy time with radiologic outcome in the pneumoreduction of intussusception in children. METHODS: From September 1995 to December 1997, a prospective analysis of 181 cases of pediatric intussusception with pneumoreduction without sedation was done. A receiver operating characteristic curve of fluoroscopy time was drawn for correlation with radiologic outcome. RESULTS: The overall success and failure rates of pneumoreduction were 84% and 16%, respectively. Three patients (1.6%) experienced colon perforation. The mean fluoroscopy time was 2.8 +/- 1.7 minutes in successful procedure and 4.9 +/- 2.8 minutes in failed procedures (P < 0.001). Analysis of the receiver operating characteristic curve of fluoroscopy time indicates that 4 minutes fluoroscopy time was a good critical point in differentiating successful and failed cases. In those 18 patients who had successful reduction with fluoroscopy times of more than 4 minutes, 4 patients had clinical symptoms for more than 1 day and 14 patients less than 1 day. One of those 4 patients required operation 1 day later because of peritonitis caused by necrosis of terminal ileum. Two patients had high fever in the next 2 days and recovered after antibiotic treatment. CONCLUSIONS: Pneumoreduction is a good method in treatment of intussusception with high successful rate. Four minutes is the critical point of procedure. Reduction with greater than 4 minutes in those patients having illness more than 1 day might not benefit and have more complications.

Poor prognosis in nasopharyngeal cancer patients with low glucose-6-phosphate-dehydrogenase activity.

Nasopharyngeal carcinoma (NPC) is endemic among well-defined ethnic groups in several world regions, such as Southeastern China and Taiwan. Glucose-6-phosphate-dehydrogenase (G6PD)- deficiency, a sex-linked disorder, is one of the most common enzymopathies in Taiwan. The major role of G6PD is to generate NADPH to protect cells from oxidative damage, which is a major contributing factor to certain degenerative diseases, such as aging and cancer. In view of the coincidence of epidemic distribution of NPC and G6PD deficiency, as well as the house-keeping function of G6PD in cellular oxidative defense, we investigated the correlation of G6PD activity with NPC. The stage of NPC was classified by AJCC (1997) criteria. G6PD levels were determined in 108 NPC male patients and 75 healthy male individuals. The mean G6PD level of NPC patients was 218.9 U/10(12) RBC or 7.53 U/g hemoglobin (Hb), being much lower than in normal individuals (260.6 U/10(12) erythrocytes (RBC) or 8.92 U / gHb). The level of G6PD activity had no correlation with tumor stage or lymph node or distant metastasis, but was significantly correlated with tumor recurrence (P = 0.004 when using G6PD = 130 U/10(12) RBC as cutoff value). These results indicated that low G6PD activity in patients with NPC is associated with poor prognosis.

Hyperinsulinemia and insulin resistance related metabolic syndrome.

BACKGROUND: A cross-sectional study in northern Taiwan was conducted to investigate the role of serum insulin level on the development of hyperglycemia, hypertension, obesity and hyperlipidemia. METHODS: Demographic data (age, gender), body mass index, blood pressure, and laboratory blood tests (uric acid, total cholesterol, triglycerides, glucose and immunoreactive insulin when fasting and two hours after loading 75 gm glucose) were collected. A logistic model or polychotomous model, treating each chronic disease (hyperglycemia, hypertension, obesity and hyperlipidemia) as a dependent variable, were fitted to study the effect of serum insulin level. RESULTS: Four hundred and twenty one volunteers (women:men = 237:184) were recruited from 1991 to 1993. Women were more obese and had more hyperglycemia, while the frequency of hyperuricemia was lower than of men. Women with a higher level of the sum of fasting and 2-hour post glucose load insulin (SIRI) levels had higher frequencies of glucose intolerance, hypertension, obesity and hyperlipidemia, whereas SIRI was related to only obesity and hyperlipidemia in men. The high plasma SIRI was a risk factor for both impaired glucose tolerance (IGT) and obesity in women. Men with a high plasma SIRI showed a more than three-fold risk of obesity. CONCLUSIONS: We have observed that a higher serum insulin level was significantly associated with the development of metabolic manifestations (glycemic status and obesity) in a suburban community in northern Taiwan. Men and women with a higher serum insulin level probably had a greater chance of developing obesity, and women had a greater chance of developing IGT.

Time trends and seasonal variations in hospital admissions for childhood asthma in Taiwan from 1990 to 1998.

The aim of the study was to determine the trends and seasonal variations in hospital admissions for childhood asthma in a tertiary medical center since 1990. Data were collected according to the age and sex of patients and obtained from hospital registries between 1990 and 1998. Children between 2 and 14 years of age admitted with the diagnosis of asthma, or asthmatic bronchitis (ICD-9 code 493) were included. Age-specific and sex-specific hospital admission rates for asthma were calculated for each calendar year. The asthma admission rates were defined as the number of asthma admissions divided by the total number of all pediatric admissions in a year. Seasonal admission rates were calculated in a similar fashion. In addition, the number of readmissions was also calculated during the study period with comparisons of sex and age differences. The asthma admission rates showed a significant upward trend throughout the period studied, particularly among the 2-4 years of age group (relative risk = 2.08; p = 0.0001). Seasonal admission rates revealed a statistically significant increase during the October-December period, peaking in November or December of each calendar year (relative risk = 1.84; p = 0.0001). There was a male predominance in both age categories during the 9-year period. Comparisons of readmissions for asthma (at least three admissions) disclosed that girls were far more likely to be readmitted than boys among the 5-14 years of age group (p = 0.01). Our results indicate 1) an increased prevalence and severity of childhood asthma in Taiwan; 2) boys and younger children aged 2-4 years with asthma had increased risks of admission for asthma (relative risks were 1.22 and 1.96, respectively) and 3) girls among the older children with asthma tend to present with greater severity than boys owing to higher relative risks of readmission for asthma.

Estimating stature from knee height for adults in Taiwan.

BACKGROUND: Many of the indices utilized in the assessment of nutritional status are dependent upon stature. Knee height has been used to predict stature in western countries when standing height cannot be measured, however, an adequate stature-knee height equation has not been established for the population in Taiwan. METHODS: A total of 1179 healthy men (603) and women (576) were recruited from those who had undergone comprehensive check-ups at their own expense from March through August 1998 at Lin-Kou Chang-Gung Memorial Hospital, Taiwan. The subjects were freely ambulatory without kyphosis or scoliosis noted on their chest X-ray or KUB films. The automatic supersonic system was used to measure stature and body weight. A Ross caliper was used to measure recumbent left knee height. Multiple linear regression was used to obtain equations to estimate stature using knee height and age. RESULTS: Stature of adults highly correlated with their knee height (r = 0.73 with 95%CI between 0.69 and 0.77 for men, and r = 0.68 with 95%CI between 0.63 and 0.72 for women) but declined with age (men: r = -0.17 with 95%CI between -0.09 and -0.24; women: r = -0.22 with 95%CI between -0.14 and -0.29). Knee height changed very little with age in both genders. To predict stature, a linear regression model should include knee height and age as predictors to reach r2 as 0.61 and 0.58 for men and women, respectively. The stature-knee height equations were "stature = 85.10 + 1.73 x knee height -0.11 x age" for men, "stature = 91.45 + 1.53 x knee height -0.16 x age" for women. CONCLUSION: Our stature-knee height equations provided good predictions on stature of adult population in Taiwan, and was superior when compared with equations developed from other populations.

The effect of nodal status on determinants of initial treatment response and patterns of relapse-free survival in nasopharyngeal carcinoma.

PURPOSE: To study the effect of regional nodal status on predictors of treatment response, failure patterns, and the time-dependent nature of the various pattern of relapse via a hazard function analysis. METHODS AND MATERIALS: We reviews tumor control data of 496 patients with nasopharyngeal carcinoma (NPC) to whom a radical course of radiotherapy (RT) with or without induction chemotherapy (CT) was given. All alive patients had a median follow-up period of 131 months. Primary tumor (T) and nodal (N) status were staged according to the TNM system of the American Joint Committee. Remote after-loading brachytherapy may be added to teletherapy in T1-2 lesions while induction CT could be given for N3 and/or T4 lesions. Hazard function analysis over 1-year interval was carried out for locoregional or distant relapse. RESULTS: T stage and brachytherapy were two independent predictors for complete response (CR) at the primary site irrespective of nodal status, whereas N stage and brachytherapy are major determinants for regional CR in node (+) patients. Multivariate analysis revealed that contributors to a relatively long disease-free interval in (1) node (-) patients were for locoregional relapse, induction CT(-) (p = 0.0062) or brachytherapy (+) (p = 0.0268) and for distant relapse, none; (2) node (+) patients were for locoregional relapse, early T stage (p = 0.0377) or regional CR (p = 0.0075) and for distant relapse, induction CT(-) (p = 0.0001) or regional CR (p = 0.0001). In node (-) or (+) patients, primary CR rate yield no independent prognostic value on various types of disease-free survival. Hazard function analysis for relapse revealed that hazard rates are in general negatively correlated with time, being highest at the first year post-treatment, decreasing from time to time, and approaching zero after a longer follow-up period in patients with locoregional CR than in patients without. CONCLUSION: Nodal status had no significant impact on predictors of primary CR, whereas in node (+) patients regional CR rate had an independent value in predicting disease-free survival to locoregional and distant relapse. Hazard function analysis revealed a decreasing hazard rate over a protracted post-treatment time in primary and regional CR patients. This indicates the continued risk of late recurrence in this subset of patients for whom long-term observation is recommended.

Locally recurrent nasopharyngeal carcinoma.

PURPOSE: To assess the outcome of and determine prognostic factors for locally recurrent nasopharyngeal carcinoma (NPC) in patients treated with a second course of radiotherapy (RT). MATERIALS AND METHODS: From 1982 to 1995, 186 NPC patients, who had initially been treated in the Department of Radiation Oncology, Chang Gung Memorial Hospital-Linkou, developed local recurrence in the nasopharynx and were re-treated with RT (>/=20 Gy). The time from the initial RT to re-treatment ranged from 8 to 136 months (median: 23 months). All patients were treated with external RT and conformal radiotherapy was used in 35 patients after 1993. Fifteen received radiosurgery as a boost treatment. The RT dose at the nasopharyngeal tumor area ranged from 20 to 67.2 Gy (median 50 Gy). Eighty-two patients received one to eight courses of cisplatin-based chemotherapy in addition to RT. RESULTS: The 1-, 3- and 5-year survival was 54.9, 22. 1 and 12.4%, respectively. Patients whose tumor relapsed later than 2 years after the first treatment had a better survival than those with earlier relapse (3-year survival: 30.1 vs. 10.8%; P=0.015), but the difference became insignificant in patients who received >/=50 Gy. Patients without evidence of intracranial invasion or cranial nerve palsy had better survival than those with such lesions (3-year survival: 30.9 vs. 3.7%; P=0.006). A re-treatment dose >/=50 Gy yielded better survival (3-year survival: 22.8 vs. 18.5%; P=0.003). Addition use of radiosurgery may improve survival. The use of chemotherapy did not improve survival. Conformal radiotherapy resulted in significantly fewer severe complications than conventional RT. CONCLUSIONS: A repeat course of RT for locally recurrent NPC successfully prolongs survival in a significant number of patients. Intracranial invasion and/or cranial nerve palsy and re-treatment dose affect the prognosis, with a dose of >/=50 Gy significantly improving survival. Radiosurgery boost may also improve survival. Our preliminary data indicates that conformal radiotherapy may decrease the severity of radiation-induced complications. However; longer follow-up and larger sample size is necessary to document the findings.

Telomerase activity is frequently found in metaplastic and malignant human nasopharyngeal tissues.

Telomerase is a specialized ribonucleoprotein polymerase that directs the synthesis of telomere repeats at chromosome ends. Accumulating evidence has indicated that telomerase is stringently repressed in normal human somatic tissues but reactivated in cancers and immortal cells, suggesting that reactivation of telomerase plays an important role in carcinogenesis. In this study, the status of telomerase activity in diseased human nasopharyngeal lesions was determined by the telomeric repeat amplification protocol (TRAP). Fifty-four patients participated including 17 inflammation or hyperplasia, eight with squamous metaplasia, and 29 with different stages of carcinomas. Telomerase activity was detected in 1 of 17 (5.9%) inflammatory or lymphoid hyperplastic tissues, 3 of 8 (37.5%) squamous metaplastic, and 25 of 29 (86.2%) carcinoma tissues. The differences in telomerase expression in these groups is statistically significant (P < 0.001). Levels of telomerase activity correlated with tumour stage (P = 0.024). These results suggest that telomerase reactivation plays a role in the carcinogenesis of nasopharyngeal cancer. Since telomerase activity is found in the majority of nasopharyngeal cancers and a subset of metaplasia, this enzyme may be served as a reference to monitoring the status of abnormal nasopharyngeal tissues.

Mortality after successful transcatheter arterial embolization in patients with unstable pelvic fractures: rate of blood transfusion as a predictive factor.

BACKGROUND: To determine the factors predictive of mortality in patients with unstable pelvic fractures after successful transcatheter arterial embolization. METHODS: A retrospective study of pelvic fractures between May of 1995 and April of 1998 was performed. Of 507 patients, 17 who were unstable underwent embolization. The success rate of embolization and the mortality rate after successful embolization were reviewed. Predictive factors (contrast medium extravasation, initial blood pressure, Injury Severity Score, timing of external fixation, time to angiography, volume of blood transfusion, rate of blood transfusion) of the final outcome were statistically analyzed. RESULTS: Embolization was 100% effective in stopping pelvic hemorrhage. The mortality of patients treated successfully with embolization was 17.6%. Among the predictive factors analyzed, only the rate of blood transfusion before embolization, 11.3 +/- 11.0 units/h (death) versus 3.2 +/- 1.9 units/h (survival) showed statistical significance with an odds ratio of 1.62 (95% confidence interval, 1.07-2.46). CONCLUSION: The success rate of embolization was 100% in stopping arterial hemorrhage of unstable pelvic fractures. The survival rate after successful embolization was 82.4%. Patients who had rapid blood transfusion before embolization had a poor final outcome. The risk of dying increased by 62% for every 1 unit/h increase of transfusion rate.

Clinical correlates of antifungal macrodilution susceptibility test results for non-AIDS patients with severe Candida infections treated with fluconazole.

Although the clinical correlates of the reference antifungal susceptibility test results in hematogenous and deep-seated Candida infection are still controversial, we evaluated the clinical correlates of this test in deep-seated Candida infections in non-AIDS patients. Thirty-two non-AIDS patients with hematogenous or deep-seated Candida infections were treated with intravenous fluconazole (400 mg a day), and the clinical outcomes were evaluated. Coexisting bacterial infections were treated with appropriate antibiotics, superinfection or reinfection was excluded, inadequate fluconazole therapy was avoided, and essential surgical intervention was performed. The MICs of fluconazole for these 32 Candida isolates were determined according to the M27-A procedure approved by the National Committee on Clinical Laboratory Standards. MICs were interpreted as susceptible (< or =8 microg/ml), dose-dependent susceptible (16 to 32 microg/ml), and resistant (> or =64 microg/ml) according to the criteria of the M27-A standard. The success rates were 79% (19 of 24; 95% confidence interval [CI], 59 to 93%) in the susceptible category, 66% (4 of 6; 95% CI, 19 to 95%) in the dose-dependent susceptible category, and 0% (0 of 2; 95% CI, 0 to 84%) in the resistant category. We conclude that the clinical correlation of the reference antifungal susceptibility test results is high in hematogenous and deep-seated Candida infections.

Amniotic membrane graft for primary pterygium: comparison with conjunctival autograft and topical mitomycin C treatment.

AIM: To study the efficacy and safety of amniotic membrane graft as an adjunctive therapy after removal of primary pterygium, and to compare the clinical outcome with conjunctival autograft and topical mitomycin C. METHODS: 80 eyes of 71 patients with primary pterygia were treated with excision followed by amniotic membrane graft. The result was compared retrospectively with 56 eyes of 50 patients receiving conjunctival autograft, and 54 eyes of 46 patients receiving topical mitomycin C. Patients were followed for at least 6 months, and the averaged follow up periods for the three groups were 13.8, 22.8, and 18.4 months, respectively. RESULTS: There were three recurrences (3.8%) in the amniotic membrane graft group, three recurrences (5.4%) in the conjunctival autograft group, and two recurrences (3.7%) in the topical mitomycin C group. There was no significant difference in recurrence rate among the three groups (p = 0.879). No major complications occurred in the amniotic membrane graft group or the conjunctival autograft group. One case of infectious scleritis due to scleral ischaemia occurred in the topical mitomycin C group. CONCLUSION: This study showed that amniotic membrane graft was as effective as conjunctival autograft and mitomycin C in preventing pterygium recurrence, and can be considered as a preferred grafting procedure for primary pterygium.

Nosocomial infections with ceftazidime-resistant Pseudomonas aeruginosa: risk factors and outcome.

Prospective studies were conducted for nosocomial Pseudomonas aeruginosa infections from February 1, 1994, to October 30, 1995. Of 97 P. aeruginosa isolates from 97 patients, 35 were resistant to ceftazidime. Logistic regression revealed previous cephalosporin or piperacillin use as independent risk factors for nosocomial ceftazidime-resistant P. aeruginosa infection. Pulsed-field gel electrophoresis revealed that four nosocomial ceftazidime-resistant P. aeruginosa infections were caused by cross-infection, probably through medical personnel.

Combined ischemic preconditioning and laser Doppler measurement for early division of pedicled groin flap.

OBJECTIVES: The main disadvantage of the pedicled groin flap for hand reconstruction is the long period of immobilization required. Early division of the pedicled groin flap is desirable for both patients and surgeons. The aims of this study were to investigate whether ischemic preconditioning can effectively accelerate the neovascularization of the junction between the donor and recipient sites in the pedicled flap, and the most objective method of judging the timing of early division of the pedicled groin flap. This report is the first prospective study to use ischemic preconditioning for early division of pedicled cutaneous flap combined with laser Doppler measurement. METHODS: The severe hand injuries of 12 patients were reconstructed by using the pedicled groin flap method. The ischemic preconditioning program was prospectively performed as scheduled for 5 to 7 days postoperatively. The pedicled groin flap was monitored with laser Doppler when the flap was elevated, inset, with clamping and nonclamping postoperatively. RESULTS: Eleven of the 12 pedicled groin flaps were divided safely and survived completely. Only one pedicled groin flap with a simultaneous harvest of iliac bone graft had partial flap loss, giving a success rate of 90.1%. CONCLUSION: With ischemic preconditioning, the pedicled groin flap can be safely divided postoperatively at a mean period of 8.4 days according to the laser Doppler measurement, especially when the perfusion unit ratio of clamping over nonclamping reaches more than 36.6%.

Comparison of indoor allergens, allergic scores, and demographic data in Taiwanese adults with asthma or allergic rhinitis, or both.

We examined the relationships between exposure to different indoor allergens and demographic factors in 515 adult Taiwanese patients with allergic diseases such as asthma and rhinitis. Patients who had positive screening results on an immunoglobulin E (IgE) test were recruited from the outpatient clinics of Chang Gung Memorial Hospital. Patients were divided into the following three groups: asthma (n = 332), combined asthma and allergic rhinitis (n = 165), and allergic rhinitis (n = 18). Serum samples were analyzed for IgE by enzyme-linked immunosorbent assay. Significantly elevated titer of dust mite-specific IgE were found in all three groups, with markedly higher levels in the combined asthma and allergic rhinitis group (p < 0.05). Allergen scores were significantly related to the demographic variables of older age (> or = 65 years), female gender, and spring season, with significantly lower scores (p < 0.05). No significant difference in allergen scores was found among cigarette smoking subjects and subjects from residential areas. Multiple linear regression analysis revealed significant allergic contributors to be, in order of importance, age, gender, and atopic disease category. We conclude that mite allergen exposure is the most significant factor associated with asthma and/or allergic rhinitis in Taiwan. Younger subjects and males had a higher rate of asthma and/or allergic rhinitis.
