Background
Systemic sclerosis (SSc) is an autoimmune connective tissue disease with vascular, fibrotic and immune changes of skin and some internal organs. Anti-heterogeneous nuclear ribonucleoproteins (anti-hnRNP) were found in SSc patients.Aim of the work
To assess anti-hnRNP A1 and A2 autoantibodies in limited SSc patients and to find their relation to clinical and hand radiographic characteristics.Patients and methods
26 limited SSc patients and 16 matched control were studied. Skin thickness was scored according to the modified Rodnan skin score method (mRss) and radiologic examination by plain X-ray of the hand and wrist was performed anti-hnRNP A1 and A2 were measured in patients and control.Results
All patients were females with a mean age of 37.5 ± 11.24 years and mean disease duration of 7.84 ± 1.19 years. 96.2% of cases showed juxta-articular osteoporosis, 38.5% with marginal erosions, 73.1% with surface erosions, 42.3% with subchondral cyst, 42.3% with metacarpophalangeal subluxation, 11.5% with marginal sclerosis, 80.8% with resorption of distal phalanges, 38.5% with resorption of distal ulna and 34.6% with calcinosis. Anti-hnRNPA1 was positive in all the patients but the anti-hnRNPA2 was positive in 21 (80.8%). Anti-hnRNP A1 and A2 showed significant difference between patients and control (5.66 ± 4.18 ng/ml vs 2.88 ± 0.82; p < 0.01 and 1.82 ± 0.36 vs 0.73 ± 0.08; p < 0.02, respectively). There was no significant correlation between the markers with the mRss or radiographic changes.Conclusion
Joint affection in SSc is more frequent than expected. Anti-hnRNP A1 and anti hnRNP A2 antigens may be useful markers for SSc patient although no significant relation was found with radiologic findings. 相似文献32.

Background and study aims
Hepatitis C virus (HCV) infection is a severe problem among patients on maintenance haemodialysis who are at particular risk for blood-borne infections because of prolonged vascular access and potential for exposure to contaminated equipment. Occult hepatitis C virus infection (OCI) is defined as the presence of HCV RNA in liver or peripheral blood mononuclear cells (PBMCs) in the absence of detectable HCV antibody or HCV RNA in the serum. In this study, we aimed to investigate the existence of occult hepatitis C virus infection in PBMCs of haemodialysis (HD) patients in one center. Moreover, we tried to link the condition to risk factors associated with HCV infection in those patients.Patients and methods
We included 40 patients with renal diseases undergoing regular haemodialysis who were repeatedly anti-HCV negative. HCV RNA detection was tested by Quantitative Real time PCR in serum and PBMCs.Results
The results of this study revealed that 23% of our haemodialysis patients have occult hepatitis C virus infection. There was a highly significant increase in ALT levels in patients with OCI versus the negative group. Also, there is a significant increase of history of blood transfusion in patients with occult HCV (p?=?0.03) while the duration of haemodialysis showed no statistical significant difference between both groups. The viral load of the occult hepatitis C virus infection subjects ranged from 581to 74,307 copies/ml.Conclusion
These results highlight the potential risk of hepatitis C virus transmission from patients within haemodialysis units in Egypt. Isolation of patients on dialysis machines depending on the results of hepatitis serological markers is not enough. Testing for hepatitis C virus -RNA in peripheral blood mononuclear cells is more reliable in identifying patients with an OCI when a liver biopsy is not available. 相似文献33.

AIMS: To report the natural history of autochthonous hepatitis E and hepatitis E virus (HEV) IgG seroprevalence in Southwest England. METHODS: Patients with unexplained hepatitis were tested for hepatitis E and cases followed until recovery or death. Five hundred blood donors, 336 individuals over the age of 60 years and 126 patients with chronic liver disease were tested for HEV IgG. RESULTS: Forty cases of autochthonous hepatitis E (genotype 3) were identified. Hepatitis E was anicteric in 25% of cases and usually caused a self-limiting hepatitis predominantly in elderly Caucasian males. Six of 40 had a significant complication and three patients died, two of who had previously undiagnosed cirrhosis. Hepatitis E shows a seasonal variation with peaks in the spring and summer and no cases in November and December. HEV IgG prevalence increases with age, is more common in men and is 16% in blood donors, 13% in patients with chronic liver disease and 25% in individuals over 60 years. CONCLUSION: Autochthonous hepatitis E is more common than previously recognized, and should be considered in the differential diagnosis in patients with hepatitis, whatever their age or travel history. It carries a significant morbidity and when seen in the context of chronic liver disease carries an adverse prognosis. 相似文献

Chlorinated pesticide residues in human breast milk from five southern Jordan districts were analyzed in 2012/2013. The total number of samples from all districts was 100. The number of samples gathered from each district was collected according to their population densities. The present study shows that 59% of the samples which contained pesticides’ residues were p,p’-DDE, 30% contained β-HCH, 10% contained p,p′-DDT, 6% contained α-HCH, 2% contained heptachlor and 1% contained endrin. These human milk samples were free of aldrin, dieldrin, α-endosulfan, β-endosulfan, HCB, γ-HCH, o,p′-DDD, o,p′-DDT and o,p′-DDE. The levels of the six mentioned compounds detected in all mother’s milk samples were higher in Ghor El-Safi district compared with the other four districts. In this study, it is recommended to continue the pesticides residues monitoring in all parts of Jordan, particularly in Ghor El-Safi district and other regions in the cultivated Jordan Valley. 相似文献

Two simple, sensitive, and rapid spectrofluorimetric methods were developed and validated for the determination of albendazole. The first method (method I) was based on the quenching effect of albendazole on the native fluorescence of erythrosine B. The fluorescence intensity was measured at 554 nm after extraction at 527 nm. In the second method (method II) the drug was reacted with lanthanum(iii) ions to form a metal complex, which was measured at 340 nm after excitation at 295 nm. The suitable pH was 3.4 (Teorell–Stenhagen buffer) and pH 5.5 (phosphate buffer solution), for method I and II, respectively. The influence of experimental factors on the fluorescence intensity of the reaction products was investigated and optimized. The linear concentration ranges were 0.2–3.5 and 0.06–0.90 μg mL−1, with detection limits of 0.049 and 0.019 μg mL−1 for method I and II, respectively. ICH guidelines were followed for validation of the developed procedures, and the results were acceptable. The Gibb''s free energy change of the reactions was −24.6 and −27.5 kJ mol−1 for method I and II, respectively. These negative values indicated the high feasibility of these reactions at ambient temperature. The proposed procedures were applied successfully for the determination of albendazole in commercial dosage forms and spiked human plasma. The results showed high precision, accuracy and recovery of the reported methods without any significant interference from pharmaceutical excipients or plasma components.Complexation of albendazole with erythrosine B quench the native fluorescence of the dye while complexation of the drug with lanthanum (iii) ions enhance the fluorescence of the drug. 相似文献

Introduction
Pharyngitis is one of the major and commonly seen presentations in pediatric emergency departments. While it could be caused by both bacterial and viral pathogens, antibiotics are improperly prescribed regardless of the pathogen. Inappropriate usage of antibiotics has risen the concern of microbial resistance and the need for stricter guidelines. Many guidelines have been validated for this reason, and the Centor score (Modified/McIsaac) is most commonly implemented. This study aims to assess the adherence and enumerate the reasons behind the suboptimal adherence to guidelines (Centor/McIsaac score) of pediatric emergency department physicians in the diagnosis and management of GABHS pharyngitis to lay the groundwork for future actions and to employ educational programs and implement local guidelines for the prevention of the development of multi-drug resistant microorganisms.Methodology
We surveyed pediatric emergency department physicians of ten teaching hospitals of Riyadh, Saudi Arabia. We used convenient sampling and estimated a sample size of 170 physicians, and interns and medical centers without pediatric emergency department were excluded from the study. Elements of the Centor score (Modified/McIsaac) were used as a part of the assessment of physicians’ knowledge of the guidelines. Adherence was assessed by requiring the participants to answer questions regarding their usage of diagnostic means when they suspect a bacterial cause of pharyngitis, as recommended by the guidelines.Results
A total of 243 physicians answered the questionnaire, 43 consultants (17.6%) and 200 non-consultants (82.4%). On the knowledge score, 9.1% scored 0, and the majority of both groups, 46.5%, earned a score of 1. The remainder 44.4%, earned a score of 2. Adherence to guidelines was defined as when diagnostic tests (throat culture or rapid antigen detection test) were always requested prior to prescribing antibiotics when acute bacterial pharyngitis was suspected. Only 27.3% (n?=?67) of our sample are adherent to guidelines, whereas the majority, 72.7% (n?=?175), are non-adherent. Several factors were assessed as reasons for lack of adherence.Conclusion
Lack of knowledge and adherence to guidelines is prevalent in our setting, with awareness, knowledge, and behavior of physicians playing as major factors behind this low adherence. Studies should aim towards the assessment of adherence towards locally developed guidelines.37.

This study was aimed to evaluate different management modalities for peripheral vascular trauma in children, with the aid of the Mangled Extremity Severity Score (MESS). A single-center retrospective analysis took place between 2010 and 2017 at University Hospitals, having emergencies and critical care centers. Different types of vascular repair were adopted by skillful vascular experts and highly trained pediatric surgeons. Patients were divided into three different age groups. Group I included those children between 5 and 10 years; group II involved pediatrics between 11 and 15 years; while children between 16 and 21 years participated in group III. We recruited 183 children with peripheral vascular injuries. They were 87% males and 13% females, with the mean age of 14.72 ± 04. Arteriorrhaphy was performed in 32%; end-to-end anastomosis and natural vein graft were adopted in 18% and 29% respectively. On the other hand, 20% underwent bypass surgery. The age groups I and II are highly susceptible to penetrating trauma ( p = 0.001), while patients with an extreme age (i.e., group III) are more susceptible to blunt injury ( p = 0.001). The MESS has a significant correlation to both age groups I and II ( p = 0.001). Vein patch angioplasty and end-to-end primary repair should be adopted as the main treatment options for the repair of extremity vascular injuries in children. Moreover, other treatment modalities, such as repair with autologous vein graft/bypass surgery, may be adopted whenever possible. They are cost-effective, reliable, and simple techniques with fewer postoperative complication, especially in poor/limited resources. 相似文献

Background
Ramadan fasting is associated with the risk of acute complications including hypoglycaemia. Therefore, patients' education before Ramadan and follow up during Ramadan is essential for safe fasting.Objectives
To evaluate the effect of pre-Ramadan education program on biochemical parameters and the risk of hypoglycaemia in patients with type 2 diabetes mellitus.Methods
A prospective interventional controlled design was carried out on 320 Muslim patients with type 2 diabetes. They were divided into 2 groups; the control group (n?=?200) who received standard diabetic care and the intervention group (n?=?120) who received focused individualized diabetic education sessions before Ramadan. The study was carried out on 3 phases (before, during and after Ramadan). Post-education change of hypoglycaemia risk and biochemical parameters during Ramadan fasting were the primary outcomes.Results
Fasting blood glucose decreased significantly during, and after Ramadan in both groups (P?<?0.001). Hypoglycaemia during fasting occurred in 4.1% of patients in the intervention group vs. 19.5% in the control group. Post Ramadan reduction of HbA1c?<?7% increased statistically significantly in the intervention group (from 20.8% of patients before Ramadan to 55.8% after Ramadan). Low-density lipoprotein cholesterol decreased in the intervention group (P?=?0.024). The body weight of the patients did not significantly change in both groups.Conclusion
There was a significant impact of pre-Ramadan educational program on reduction of hypoglycaemic risk and other acute complications, reduction of low-density lipoprotein cholesterol and improvement of high-density lipoprotein cholesterol. Therefore, it is recommended for the fasting patients especially those with high and very high risk during Ramadan. 相似文献40.

LH pulses during the progesterone (P)-induced LH surge were examined in ovariectomized and estrogen-treated female monkeys. Animals received a 2.5-mg P or oil injection 24 h after administration of 30 micrograms estradiol benzoate. The animals were fitted with jugular catheters connected to a tether-swivel system. Blood samples were collected at 10-min intervals starting 3-4 h before and ending 12-20 h after P or oil injection. Plasma LH was measured by both bioassay and RIA. LH pulses were determined by the PULSAR program. P administration induced a BIA-LH surge with a latency of 71 +/- 10 min in all seven animals. The P-induced bioassayable LH (BIA-LH) surge consisted of an ascending phase (204 +/- 24 min), a plateau period (174 +/- 32 min), and a descending phase (376 +/- 60 min). Oil injection did not cause a LH surge (n = 4). BIA-LH release before P and that during the P-induced LH surge were pulsatile. Pulse intervals of BIA-LH before P treatment (57.1 +/- 5.2 min) were not different from those before (55.0 +/- 11.7 min) and after (62.9 +/- 16.3 min) oil injection. In contrast, pulse intervals during the ascending phase (35.0 +/- 4.0 min), plateau period (34.6 +/- 2.6 min), and descending phase (45.0 +/- 3.1 min) were significantly shorter (P less than 0.02) than those before P. Pulse amplitudes of BIA-LH during the ascending phase (125.3 +/- 28.7 ng/ml) and plateau period (253.9 +/- 27.0 ng/ml) were significantly (P less than 0.001) higher than those (44.7 +/- 12.6 ng/ml) before P and during the descending phase (66.9 +/- 11.1 ng/ml). Radioimmunoassayable LH results were quite similar to those for BIA-LH, except that amplitude changes in radioimmunoassayable LH after P treatment were smaller than those in BIA-LH. It was concluded, therefore, that both the frequency and amplitude of pulsatile LH release increase during the P-induced LH surge, especially during the ascending phase and plateau period, in female rhesus monkeys. Furthermore, the present results support our previous conclusion that P facilitates pulsatile LHRH release with increases in frequency and amplitude in ovariectomized and estrogen-treated monkeys. 相似文献
