BACKGROUND AND OBJECTIVES: Peripheral Neuropathy (PN) is one of the late complications of Diabetes Mellitus. Cranial nerves III, VII and V are among the most commonly affected in diabetic patients. Traditional Electrodiagnosis (Edx) studies are useful method for diagnosis of PN and symptomatic cranial neuropathy, and may not be useful for detecting subclinical involvement of cranial nerves. The main objective of this study is to evaluate the role of Blink Reflex (BR) for early diagnosis of cranial neuropathy in diabetic patients with PN. DESIGN: A prospective study was performed on NIDDM patients with a PN. 188 subjects were included in our study in which 142 acted as healthy subjects and 46 as diabetic patients. Patients were excluded with prior history of cranial nerve lesions, stroke, and other disease with polyneuropathy or drug-induced neuropathy. Routine nerve conduction studies were performed and only patients with PN were included in this study. RESULTS: Abnormalities were found in 54.4% of patients. R1, IR2 and CR2 were prolonged relative to healthy group. Statistically there was no significant difference in R/D ratio of patients (P = 0.201). Also there was a positive correlation between R1, IR2 and CR2 latencies with duration of diabetes and severity of polyneuropathy, but not for R/D. The greatest correlation was shown in R1 latency (69.9% abnormality). CONCLUSION: BR is a non-invasive and very useful method for evaluation and diagnosis of subclinical cranial nerve involvement in diabetic patients. 相似文献

OBJECTIVE: If additional chemicals are inadvertently introduced in the preparation of radiopharmaceutical kits, radiochemical impurities may be formed. We report our experience with erroneously diluting (99m)Tc-pertechnetate eluate with 5% dextrose solution rather than normal saline during the preparation of (99m)Tc-tetrofosmin, (99m)Tc-methylene diphosphonate (MDP), (99m)Tc-stannous colloid, and (99m)Tc-mebrofenin. METHODS: Scintigrams for 3 of the 4 radiochemicals unintentionally prepared with 5% dextrose were found to have an altered biodistribution. Therefore, radiopharmacy procedures for the day were reviewed, and instant thin-layer chromatography (ITLC) was performed. RESULTS: Scintigrams showed an altered biodistribution consistent with an impurity. Review of procedures that day uncovered the error of using 5% dextrose to dilute the (99m)Tc eluate. The altered biodistribution on (99m)Tc-stannous colloid, (99m)Tc-MDP, and (99m)Tc-mebrofenin scintigrams consisted of cardiac blood-pool activity (possibly as a result of slow clearance of (99m)Tc-dextrose), soft-tissue background activity (possibly as a result of interstitial distribution of (99m)Tc-dextrose), renal and bladder activity (possibly as a result of renal elimination of (99m)Tc-dextrose), and gallbladder activity (possibly as a result of hepatobiliary excretion of (99m)Tc-dextrose). Both scintigrams and ITLC showed no evidence of impurities for the (99m)Tc-tetrofosmin prepared using 5% dextrose. CONCLUSION: Unintended preparation of radiochemicals with 5% dextrose rather than normal saline often results in the production of impurities, possibly (99m)Tc-dextrose. Because some but not all commercial radiochemical kits prepared with 5% dextrose will suffer this fate, nuclear medicine physicians reviewing the day's images will be confronted with a confusing combination of expected and grossly abnormal findings. 相似文献

Production of monoclonal antibodies to HLA-G, a nonpolymorphic antigen of non-classical HLA class I, is of basic and clinical importance. In the present study, monoclonal antibodies were prepared which recognize different membrane bound and soluble isoforms of HLA-G, following immunization of BALB/c mice with a synthetic peptide. Use of this peptide (23 residues), which is present in the alpha1 domain of HLA-G, was previously demonstrated to provide antibodies useful for recognition of HLA-G isoforms in human placenta. Antibody-producing hybridomas were screened by an indirect one-step ELISA method. A clone designated 5E6H7, secreted antibodies useful in immunostaining studies involving both surface HLA-G of placental tissues and soluble forms of this antigen in human sera. In addition, unreactivity of this antibody with human lymphocytes and sections of normal human skin was observed by immunofluorescence microscopy, thus demonstrating its specificity for HLA-G. 相似文献

PURPOSE: Local excision of germ cell tumor in the remaining testicle followed by a modest dose of irradiation is an alternative to orchiectomy. This organ sparing technique provides superior quality of life and reduces the need for lifelong hormone replacement. MATERIALS AND METHODS: We treated two patients with contralateral seminomas with organ preservation. Both patients received postoperative irradiation to the remaining testicle to a dose of 20 Gy in 10 fractions and 19.8 Gy in 11 fractions. RESULTS: Both patients are alive with no evidence of disease more than 3 years since the completion of their treatments. They both have reduced but preserved androgen production and retained their virility. They both are azospermic. CONCLUSION: We conclude that organ preservation for the treatment of contralateral testicular seminoma is a superior alternative to orchiectomy of the remaining testicle. It preserves male hormone production with equal survival outcome expectations. 相似文献

Potential of wastewater treatment in car industry and groundwater contamination by volatile organic compounds include perchloroethylene (PCE), trichloroethylene (TCE) and dichloromethane (DCM) near car industry was conducted in this study. Samples were collected in September through December 2011 from automobile industry. Head-space Gas chromatography with FID detector is used for analysis. Mean PCE levels in groundwater ranged from 0 to 63.56 μg L?1 with maximum level of 89.1 μg L?1. Mean TCE from 0 to 76.63 μg L?1 with maximum level of 112 μg L?1. Due to the data obtained from pre treatment of car staining site and conventional wastewater treatment in car factory, the most of TCE, PCE and DCM removed by pre aeration. Therefor this materials entry from liquid phase to air phase and by precipitation leak out to the groundwater. As a consequence these pollutants have a many negative health effect on the workers by air and groundwater. 相似文献

[Purpose] The aim of this study was to investigate the efficacy of neuromobilization
combined with routine physiotherapy in patients with carpal tunnel syndrome through
subjective, physical, and electrophysiological studies. [Subjects and Methods] Twenty
patients with carpal tunnel syndrome (totally 32 hands) were assigned two groups:
treatment and control groups. In both groups, patients received the routine physiotherapy.
In addition to the routine physiotherapy, patients in the treatment group received
neuromobilization. The symptoms severity scale, visual analogue scale, functional status
scale, Phalen’s sign, median nerve tension test, and median nerve distal sensory and motor
latency were assessed. [Results] There were significant improvements in the symptoms
severity scale, visual analogue scale, median nerve tension test, and Phalen’s sign in
both groups. However, the functional status scale and median nerve distal motor latency
were significantly improved only in the treatment group. [Conclusion] Neuromobilization in
combination with routine physiotherapy improves some clinical findings more effectively
than routine physiotherapy. Therefore, this combination can be used as an alternative
effective non-invasive treatment for patients with carpal tunnel syndrome.Key words: Carpal tunnel syndrome, Neuromobilization, Electrophysiological measures 相似文献

Objective
We estimated pubertal development of 7,493 normal Iranian girls aged 6 to 20 years in a cross-sectional study.Methods
Pubertal stages were assessed according to Tanner. The mean ages to achieve secondary sexual characteristics as well as the mean age at menarche were estimated. Weight and height were measured and body mass index (BMI) was calculated. Reference curves for different breast stages and menarche were constructed. The percentiles for attaining each stage were compared to data proposed by Tanner.Findings
The mean age at breast bud stage (B2) was 10.10, pubic hair stage (P2) was 9.83, and menarche age was 12.55 years. The anthropometric variables were interpreted in different maturity stages. The mean age at attainment of puberty was compared with those of other populations.Conclusion
Not only the onset of puberty in Iranian girls but also the duration of puberty is similar to data from most other countries. A lower age limit for the definition of precocious puberty than the traditional 8 years is documented for Iranian girls. However, it should be noted that considering the rate of evolution of pubertal findings is more important than the age of their appearance. 相似文献30.

The objective of this study was to evaluate the effectiveness of case-management services and the feasibility of considering
the Consumers’ Family Members (CFM) as service providers in Iran as a developing country. Three trained case-managers were
allocated into each group (Mental Health Worker-MHW and CFM), providing 12 months of home-visit services for 129 individuals
with schizophrenia. Burden, knowledge, quality of life and the general health condition of the caregivers, as well as positive/negative
symptoms and social skills of the consumers were evaluated. Most clinical variables were improved without significant differences
between groups. The hospitalization rate was reduced by 67%. 相似文献
