Cognitive determinants of cervical cancer screening behavior among housewife women in Iran: An application of Health Belief Model

Our aim in this cross-sectional study was to assess the cognitive determinants of Cervical Cancer Screening Behavior (CCSB) among housewife women in Islamabad County, Iran. Through multistage random sampling we recruited and interviewed 280 housewife women. The women who perceived more benefits of performing the Pap test (OR = 1.11), and perceived fewer barriers (OR = 0.915), and higher self-efficacy to perform the test (OR = 1.12) were more likely to have a CCSB in the previous three years. Our findings are informative for the development of targeted interventions to foster CCSB among housewife women.     

Simvastatin-induced myocardial protection against ischemia-reperfusion injury is mediated by activation of ATP-sensitive K+ channels

OBJECTIVES: Previous studies have suggested that the 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors attenuate ischemia-reperfusion injury. We investigated whether pretreatment with simvastatin reduces myocardial infarct size and whether glyburide, a non-selective inhibitor of the ATP-sensitive K channels, abrogates this infarct size-limiting effect. METHODS: Sprague-Dawley rats were treated with either simvastatin (20 mg/kg per day) or saline alone for 3 days. Additional groups of rats were treated as above and on the fourth day they received intravenous glyburide (0.3 mg/kg). All rats underwent 30 min of coronary artery occlusion followed by 180 min of reperfusion. Ischemic myocardium at risk was assessed with blue dye and infarct size with triphenyltetrazolium chloride. RESULTS: Infarct size, expressed as a percentage of the myocardium at risk, was significantly smaller in the simvastatin group (n = 8, 20.8 +/- 3.4%) than in the placebo group (n = 6, 40.1 +/- 2.7%) (P = 0.001). Glyburide abolished the protective effect of simvastatin with infarct size being 34.2 +/- 6.9% and 29.7 +/- 3.9% of the area at risk in the simvastatin group (n = 7) and placebo (n = 7) group, respectively (P = 0.58). CONCLUSIONS: Simvastatin significantly reduced myocardial infarct size. The protective effect was completely abrogated by glyburide, strongly suggesting that this protective effect is mediated via activation of the ATP-sensitive K channels.     

Sustained-release methylphenidate in methamphetamine dependence treatment: a double-blind and placebo-controlled trial

Background

The objective of this randomized, double-blind, placebo-controlled study was to evaluate the efficacy of sustained-release methylphenidate (MPH-SR) in treatment of methamphetamine dependence.

Methods

Fifty-six individuals who met DSM-IV-TR criteria for methamphetamine dependence participated in this 10-week trial. The participants were randomly allocated into two groups and received 18 to 54 mg/day sustained-released methylphenidate or placebo for 10 weeks. Craving was evaluated by a visual analogue craving scale every week. Urinary screening test for methamphetamine was carried out each week. The Beck Depression Inventory-II (BDI-II) was used to monitor participant depressive symptoms at baseline and bi-weekly during the treatment period.

Results

At the end of the trial, the MPH-SR group was less methamphetamine positive compared to the placebo group and the difference was significant (p = 0.03). By the end of the study, MPH-SR group showed significantly less craving scores compared to the placebo group [MD (95% CI) = -10.28(0.88-19.18), t(54) = 2.19, p = 0.03]. There was greater improvement in the depressive symptoms scores in the intervention group compared to the placebo group [MD (95% CI) =2.03(0.31-3.75), t (54) =2.37, p = 0.02].

Conclusion

Sustained-released methylphenidate was safe and well tolerated among active methamphetamine users and significantly reduced methamphetamine use, craving and depressive symptoms.

Tumor necrosis factor-alpha and neuropsychiatric lupus erythematosus: relation to single photon emission computed tomography findings

This study was designed to highlight the relation of tumor necrosis factor- (TNF-) to neuropsychiatric lupus (NPLE) manifestations. The relation of TNF- to the type of single photon emission computed tomography (SPECT) findings in this context was also studied. Twenty-one systemic lupus erythematosus (SLE) females, mean age 27.57 ± 9.89 years, and twenty age-matched normal females (controls), were subjected to TNF- assessment. Different clinical and neuropsychiatric manifestations were evaluated. SPECT was carried out for all patients. The results showed that the mean TNF- level (pg/ml) was significantly raised in patients compared with controls (167.8 ± 102.5 versus 64 ± 50.2, respectively, P 0.005). Thirteen patients (69.1%) had NPLE manifestations. NPLE patients had a significantly higher mean TNF- than patients without NPLE (203 ± 102.8 versus 109 ± 47.3, respectively, P 0.03). Positive SPECT findings were found in 18 lupus patients (85.7%), including all 13 patients with NPLE (100% sensitivity), with a multiple focal pattern of hypoperfusion being the most frequent type (9/13), followed by diffuse (3/13), and then single focal pattern (1/13). The mean TNF- was significantly higher in patients with multiple focal pattern (P 0.001). In conclusion, results of this work support the hypothesis that TNF- could be involved in the pathogenesis of NPLE, and hence, it could be speculated that the evolving anti-TNF therapy can play a potential role in the management of this disease.     

Arthritis and osteonecrosis in a patient with thrombophilia

This case report describes a very rare entity of thrombophilia manifesting as persistent arthritis and digital ulcers. A 9-year-old Egyptian girl presented with a 2-year history of persistent arthritis and digital ulcers. The case was followed up after 4 years. The clinical manifestations and laboratory investigations are recorded. Thrombophilia with partial protein C deficiency appeared to be responsible for the clinical manifestations with underlying ipsilateral osteonecrosis of patella and calcaneum and resorption of the terminal phalanges. Her older sister showed the same picture with additional pulmonary hypertension. In conclusion, arthritis and osteonecrosis appear as a rare presentation of thrombophilia and protein C deficiency, and ignorance of this may lead to misdiagnosis or confusion with other childhood rheumatic diseases.     

Comparative study of anti‐CCP and RF for the diagnosis of rheumatoid arthritis

Aim: To determine the frequency of anti‐cyclic citrullinated peptide antibody (anti‐CCP) in a group of patients with rheumatoid arthritis and another group with other rheumatic diseases. Patients and methods: Anti‐CCP1 and rheumatoid factor (RF) titres were determined in 320 serum samples; 136 from RA patients, 184 from control patients (165 patients with rheumatic diseases other than RA, and 21 patients with lymphoproliferative diseases). Results: The sensitivity of Anti‐CCP was 62.5% (95% CI: 53–70%) for the diagnosis of RA with a specificity of 89.1% (95% CI: 83–93%). The sensitivity of RF was 85.3% (95% CI: 79–91%). The specificity was 64.7% (95% CI: 57–71%). Conclusions: Anti‐CCP1 has not very high specificity for RA regarding other rheumatic disease. However it is still very helpful for the diagnosis of RA.     

The clinical patterns of myalgia in children with familial Mediterranean fever

OBJECTIVES: To study the frequency and clinical patterns of myalgia in a defined group of children with familial Mediterranean fever (FMF). METHODS: A prospective 4-year (September 1995-September 1999) study of children with FMF seen in the pediatric FMF clinic of Jordan University teaching hospital. Diagnosis of FMF was made according to published criteria. Once the diagnosis of FMF and myalgia was made, details about myalgia were collected by interview with the child and his/her parents and entered into a special study form. RESULTS: Of 264 children with FMF seen over the study period, 65 (25%) developed myalgia. Three clinical patterns of myalgia were identified: the spontaneous pattern, the exercise-induced pattern, and the protracted febrile myalgia syndrome (PFMS), seen in 8%, 81%, and 11% of patients, respectively. The three patterns differed in the severity of pain, height of fever, and duration of the episode. In 33 children with the exercise-induced myalgia, in which response to colchicine could be reliably assessed, a favorable response was achieved in 97%. Three children with the PFMS had a dramatic response to corticosteroids. CONCLUSIONS: Myalgia in children with FMF is common and can follow three different clinical patterns.
