In order to assess the effect of the neonatal tetanus elimination program in Turkey, tetanus antibody prevalence among women of childbearing age from three selected provinces was evaluated in relation to vaccination doses of the single-type tetanus vaccine. A combined method of in-house enzyme-linked immunosorbent assay and particle agglutination test was used to determine tetanus antibody titers. Among 205 women aged 20-39 years, the tetanus antibody level was higher in women with 1-3 children than those without children. The geometric mean of the log antibody titer was increased proportionally with a slope of 0.405 +/- 0.174 per dose between 0 and 3 doses (P > 0.05). However, the proportion of 20-39-year-old women with the protective antibody in the provinces ranged from 54.8 to 86.6%. Diyarbakir had the lowest immunity with a larger number of children in the household, and a lower educational level. The results of our serological study demonstrated that the neonatal tetanus elimination program in Turkey is effectively promoting immunity against tetanus in pregnant women. However, the study also revealed that the tetanus immunity among women of childbearing age was still insufficient. Intensive implementation of the supplemental immunization activities and encouraging vaccinations through neonatal care services will improve the situation.  相似文献

OBJECTIVES: To investigate the effect of abdominal massage on clinical aspects of bowel dysfunction and colonic transit time in patients with spinal cord injury. Twenty-four patients were placed on a standard bowel program (phase I), after which abdominal massage was added to the regimen (phase II). Parameters of gastrointestinal system function and colonic transit times were evaluated. DESIGN: Uncontrolled clinical study. RESULTS: Eleven (45.8%) of the 24 patients had abdominal distention, and 10 (41.7%) had fecal incontinence in phase I; corresponding results for phase II were three (12.5%) and four (16.7%) (P = 0.008 and 0.031, respectively). There were no significant differences between the proportions of patients with difficult intestinal evacuation or abdominal pain or in mean time required for bowel evacuation in phase I vs. phase II. The mean frequencies of defecation in phases I and II were 3.79 +/- 2.15 (2.75-4.55) and 4.61 +/- 2.17 (3.67-5.54) bowel movements per week, respectively (P = 0.006). Mean total colonic transit time decreased from 90.60 +/- 32.67 (75.87-110.47) hrs in phase I to 72 +/- 34.10 (58.49-94.40) hrs in phase II (P = 0.035). CONCLUSIONS: Abdominal massage has positive effects on some clinical aspects of neurogenic bowel dysfunction in patients with spinal cord injury.  相似文献

The objective of this study was to determine the incidence, perinatal complications and the outcome of macrosomic infants. A retrospective analysis was made of macrosomic deliveries and of those admitted into the Neonatology Unit. A control group of 854 deliveries weighing between 2500-4000 g was randomly composed. The incidence of macrosomic deliveries, stillbirth rates, sex, parity, maternal age, mode of delivery, perinatal complications like birth traumas, hypoglycemia, polycythemia, asphyxia, admission rate into the neonatal intensive care unit (NICU), and outcome were analyzed. Among a total of 11,827 deliveries, 829 (7%) were macrosomic neonates. Statistical analysis showed male predominance (p = 0.0001), a significant increase in cesarean section (p = 0.0001), and higher parity for the macrosomic group (p = 0.0001). The mothers of macrosomic newborns were older (p = 0.0001). The admission frequency of macrosomic deliveries into the NICU was almost two-fold. Birth injuries were found in 53 (6.4%) macrosomic infants, and macrosomic deliveries had a two-fold risk for birth injuries. Statistical analysis showed a significant difference between macrosomics and the control group for the frequency of birth traumas (p = 0.0007), hypoglycemia (p = 0.0001) and polycythemia (p = 0.0006). There were two deaths in macrosomic group versus one among control cases. Regarding the high birth trauma and NICU admission rates of macrosomic infants, it is important to emphasize the significance of prenatal diagnosis of fetal macrosomia and of management of these high-risk pregnancies in tertiary level hospitals.  相似文献

OBJECTIVES: This study was designed to determine the effect of exercise on the physical fitness level and quality of life in postmenopausal women. 81 volunteer postmenopausal women who entered the menopause naturally and have been taking hormone replacement treatment (HRT) were divided randomly into two groups: exercise (n=41) and control (n=40). METHODS: Physical fitness tests and the Nottingham Health Profile (NHP) were used to assess physical fitness and quality of life in both groups, both before and after 6 weeks. The study group participated in an exercise programme, which was composed of sub-maximal aerobic exercises for a 6-week period 3 times a week. The statistical analyses were done by paired samples t-test and independent samples t-test. RESULTS: At the end of 6 weeks exercise period, when the two groups were compared after the exercise period, we found statistically significant differences in strength, endurance, flexibility and balance parameters in the exercise group (P<0.05). There was also a statistically significant change in the exercise group for the NHP indicating an improvement in the quality of life (P<0.05). CONCLUSIONS: In this study, it was concluded that the fitness level and quality of life on postmenopausal women could be improved by a regular and controlled exercise programme of 6 weeks.  相似文献

PURPOSE: The aim of this preliminary study was to determine the possible relationship between alkaline phosphatase (ALP) levels in the gingival crevicular fluid (GCF) and periodontal disease in men with hypergonadotropic hypogonadism (HH). MATERIALS AND METHODS: A total of 41 patients were divided into four groups. 9 with HH and periodontitis (P/HH), 11 with HH and gingivitis (G/HH), 12 with systemically healthy and periodontally healthy (H/C) and 9 with systemically healthy and periodontitis (P/C). The clinical evaluation of patients was based on the following parameters; the plaque index (PI), gingival index (GI), probing depths (PD) and attachment level (AL). The levels of ALP in the GCF were measured by enzyme-linked immunosorbent assay (ELISA). RESULTS: No significant difference could be detected in the mean clinical parameter data between the P/HH and P/C groups (p > 0.05). The periodontitis patients in both groups (P/C and P/HH) had higher mean probing depths than the H/C and G/HH patients (p < 0.001). The concentrations and total amounts of ALP in the GCF were significantly higher in both periodontitis groups compared to healthy and gingivitis groups (p < 0.01). The serum ALP levels were significantly higher in the P/HH group when compared to the other groups (p < 0.001). CONCLUSION: The findings of this study suggested that HH could be implicated as a contributing factor to the progress of periodontal disease.  相似文献

In the present study, the genotoxic effects of the low-calorie sweetener aspartame (ASP), which is a dipeptide derivative, was investigated using chromosome aberration (CA) test, sister chromatid exchange (SCE) test, micronucleus test in human lymphocytes and also Ames/Salmonella/ microsome test. ASP induced CAs at all concentrations (500, 1000 and 2000 microg/ml) and treatment periods (24 and 48 h) dose-dependently, while it did not induce SCEs. On the other hand, ASP decreased the replication index (RI) only at the highest concentration for 48 h treatment period. However, ASP decreased the mitotic index (MI) at all concentrations and treatment periods dose-dependently. In addition, ASP induced micronuclei at the highest concentrations only. This induction was also dose-dependent for 48 hours treatment period. ASP was not mutagenic for Salmonella typhimurium TA98 and TA100 strains in the absence and presence of S9 mix.  相似文献

Progressive facial hemiatrophy (PFH), Parry-Romberg syndrome, is a rare disorder frequently associated with epilepsy. We describe a 28-year-old man who had PFH and partial epilepsy that was easily controlled with antiepileptic drugs. In accordance with this patient's benign course of seizures, the cortical silent period was prolonged in the symptomatic hemisphere. This finding may represent compensatory interictal mechanisms in epilepsy.  相似文献

Advanced maternal age is the only fully accepted risk factor for trisomy 21, while most children with Down syndrome (DS) are born to younger mothers (<35 years). The relationship between chromosomal nondisjunction leading to aneuploidy and folate metabolism has drawn attention in the recent years. In this study, we examined the two polymorphisms in genes encoding the folate metabolizing enzyme methylenetetrahydrofolate reductase (MTHFR), namely, 677C > T and 1298A > C. The prevalence of these variant genotypes in mothers of DS children (case mothers) (n = 152) was compared with controls (n = 91). Frequencies of MTHFR 677C > T genotypes (CC, CT, and TT) and also combination of heterozygous and homozygous variant genotypes (CT or TT) (P = 0.28) demonstrated no difference between the case and control groups. Genotype frequencies of MTHFR 1298A > C (AA, AC, and CC) were similar among the case and control mothers. Variant genotypes of MTHFR 1298A > C (AC or CC) were also insignificant when compared between the two groups. This is yet the largest case-control study conducted for MTHFR 677C > T and also the first to investigate a possible relation with MTHFR 1298A > C. The data presented in this study fail to support the relationship between MTHFR 677C > T and 1298A > C polymorphisms and risk of having a child with DS.  相似文献
