An epidemiological survey of psychiatric disorders in Iran

Background

The nation-wide epidemiological survey of psychiatric disorders in term of lifetime prevalence is not adequately known in Iran. The prevalence of lifetime psychiatric disorders was estimated among the population of aged 18 and over on gender, age group, educational level, occupational status, marital status, and residential area.

Methods

The subjects were 25,180 individuals selected through a clustered random sampling method. The psychiatric disorders were diagnosed on the bases of Diagnostic and Statistical Manual of Mental Disorders-IV criteria. It is the first study in which the structured psychiatric interview administered to a representative sample of the Iranian population age 18 and over by the 250 trained clinical psychologist interviewers. The data was entered through EPI-Info software twice in an attempt to prevent any errors and SPSS-11 statistical software was also used for analyses. The odds ratios and their confidence intervals estimated by using logistic regression.

Results and Discussion

The prevalence of psychiatric disorders was 10.81%. It was more common among females than males (14.34% vs. 7.34%, P < 0.001). The prevalence of anxiety and mood disorders were 8.35% and 4.29% respectively. The prevalence of psychotic disorders was 0.89%; neuro-cognitive disorders, 2.78% and dissociative disorders, 0.77%. Among mood disorders, major depressive disorder (2.98%) and among anxiety disorders, phobic disorder (2.05%) had the higher prevalence. The prevalence of psychiatric disorders among divorced and separated 22.31%; residents of urban areas 11.77%; illiterates 13.80%; householders 15.48%; unemployed 12.33% that were more than other groups.

Conclusion

The mental health pattern in Iran is similar to the western countries, but it seems that the prevalence of psychiatric disorders in Iran may be lower than these countries.It is estimated that at least about 7 millions of Iranian population suffer from one or more of the psychiatric disorders. It shows the importance of the role of the psychiatric disorders in providing preventive and management programs in Iran.

     

Perception of the risk of adverse drug reactions: differences between health professionals and non health professionals

AIMS: To investigate how risk of adverse drug reactions (ADRs) of several drug classes is perceived by health vs non health professionals. METHODS: Four hundred health professionals (i.e. 278 general practitioners, 76 pharmacists and 46 pharmacovigilance professionals) and 153 non health professionals were interviewed. Visual analogue scales were used to define a score of perceived risk of ADRs associated with each drug class (ranking from 0 to 10). RESULTS: Anticoagulants were ranked as the most dangerous drugs by general practitioners [median score (25th-75th centiles): 7.9 (6.7-9.0)], pharmacists [8.7 (7.8-9.7)] and pharmacovigilance professionals [8.1 (7.2-9.0)]. For non health professionals, the class ranked first was sleeping pills [8.7 (7.2-9.4)] followed by tranquillisers [8.2 (6.4-9.2)] and antidepressants [8.0 (5.9-9.1)]. Aspirin was listed in the last position by non health professionals [3.4 (1.5-5.4)]. CONCLUSIONS: There are major differences in the perception of risk of ADRs between health professionals and non health professionals.     

Effect of Psoas Training on Postmenopausal Lumbar Bone Loss: A 3-Year Follow-Up Study

The present study completed a previous randomized trial that demonstrated the protective effect of 1-year psoas training on lumbar bone loss in postmenopausal women. Computerized tomography had been carried out at the beginning (CT1) and at the end (CT2) of this trial. In the present study, 67 women having completed the first trial were asked to practice psoas exercises (60 hip flexions in sitting position with a 5 kg weight on the knee) for 2 additional years with a third CT control at the end of this period (CT3). The aim of this complementary study was to assess the compliance rate and long-term effect on bone of daily psoas muscle training over a longer period. Twenty-one women performed this daily psoas training for 3 years from CT1 to CT3, and 14 acted as controls during the same period. Fourteen women were controls during the first year (from CT1 to CT2) but practiced psoas training during the following 2 years (from CT2 to CT3). Four women were psoas trained during the first year (from CT1 to CT2) and subsequently crossed over to the control group for the last 2 years. The compliance rate was 42%, with an attendance rate of 88%. The lumbar bone loss was lower in the 21 women trained over the 3 years (−3.26 ± 28.45 mg/cm³) than in the 14 untrained women (−16.79 ± 8.51 mg/cm³) (P= 0.02). The bone loss was not significantly reduced between the two periods of the study in the 12 women having been controls from CT1 to CT2 and having crossed over to the active training group from CT2 to CT3. Psoas training may be effective against lumbar bone loss. We conclude that specific training may play a contributing role in the preventive strategy to avoid osteoporosis.

Diagnostic investigation of pyelonephritis

Urinary tract infections are common, especially among women, and cause significant morbidity. While prognosis is probably more dependent on whether or not an episode of urinary tract infection is complicated (ie, associated with functional, metabolic, or anatomic abnormalities of the urinary tract) or uncomplicated, anatomic localization of infection has important implications for therapy. Pyelonephritis is difficult to diagnose with a high degree of accuracy based on clinical findings alone. Radiologic imaging plays an important role in the diagnosis and management of selected patients. Noninvasive and inexpensive methods to allow accurate localization of infection are needed.     

Comparing Oral Route Paraffin Oil versus Rectal Route for Disimpaction in Children with Chronic Constipation; a Randomized Control Trial

Objective

Functional constipation is a common and challenging problem in pediatrics. Fecal disimpaction prior to maintenance therapy is recommended to ensure successful treatment. The aim of this study was to compare the efficacy and patient''s compliance of the two methods of paraffin oil administration (oral and rectal route) with the purpose of disimpaction in treatment of children with functional constipation.

Methods

A total of 80 children (49 males and 31 females) aged 1–12 years, with functional constipation according to Rome III criteria, whose rectal examination confirmed fecal impaction were divided into two groups randomly. Group I received 3 ml/kg/day paraffin oil orally and group II received 3ml/kg/day paraffin oil rectally during 3 consequent days. Successful treatment was defined as no detectable fecal impaction in rectal examination after at most 72 hours. Patient compliance and family satisfaction also was evaluated using a scored questionnaire.

Findings

Response to the treatment in both groups was with 92.5% and 82.5% in group I and II, respectively. So, there was no significant difference between the two methods of therapy. Family satisfying and compliance were obviously more achieved in group 1 (87.5% vs 57.5%) than in Group 2 (P<0.001). No parents in group I complained about type of treatment while 12.5% of parents in group II were unsatisfied with the mode of paraffin oil administration. The most common side effect of paraffin oil in both groups was anal oil seepage (27.5%). Nausea and abdominal pain were more common side effects in group 1 and 2 respectively.

Conclusion

It seems that using paraffin oil per oral route in comparison with rectal route could be a preferred option for disimpaction in children causing less anxiety to the family.     

Drug-induced bone loss: a major safety concern in Europe

Introduction: Drug-induced bone loss remains the major cause of vertebral and hip fractures and significantly associated to morbidity and mortality. This article will review the common drugs identified as the causes of bone loss and the risk factors and management in European countries.

Areas covered: Beyond glucorticoid – the most cause of osteoporosis, many different drugs could cause harmful skeletal disorders. The antiepileptics, hormonal therapy, GnRH antagonists, aromatase inhibitors are well-known cause of bone loss. Osteoporosis and fractures risk also increased with calcineurin inhibitors, antiretroviral drugs, selective inhibitors of serotonin reuptake, loop diuretics, heparins, oral anticoagulants, high doses of thyroxine and proton pump inhibitors.

Expert opinion: Drugs are an important secondary cause of osteoporosis. Healthcare professionals should reassess the requirement for drugs and use the lowest dosage and shortest duration. Lifestyle changes, adequate calcium, vitamin D supplement, appropriate monitoring of bone status and initiating osteoporosis treatment if indicated are recommended when drugs having potential deleterious effects on bone are used, particularly in high risk patients. The update and further studies would provide concluded evidences of controversial drugs induced bone loss and determine the best prevention and treatment strategies.     

Gender differences among homeless people in Tehran,Iran

Aim

Gender differences among homeless people may affect the frequency of their risky behaviours. This study was conducted to evaluate the behaviour patterns of homeless men and women in Tehran and compare the probable differences.

Subject and methods

In this study, 593 homeless people were recruited from five centres that house homeless people in Tehran, the capital city of Iran. A researcher-designed questionnaire was used to study behavioural patterns.

Results

In this study, homeless people (513 males and 80 females, all Iranian nationals) were enrolled in the study from June to August 2012. Mean age and mean duration of homelessness among women (35.46 and 12.68 months) were lower than those among men (42.74 and 56.85 months) (p?=?0.001). Although lifetime history of incarceration in men was higher than in women (p?=?0.002), mean duration of imprisonment in the last 10 years in men (21.25 months) and women (17.76 months) was not statistically different (p?=?0.07). Accommodation locality in the past 6 months varied between men and women. Women were current drug users more often than men were (61.53 % versus 45.26 %) (p?=?0.02). The type of drug consumption in women (methamphetamine) differed from that of men (opium and heroin). More men had a history of injecting drugs than did women (30.02 % versus 12.30 %) (p?=?0.003). Condom use at the last sexual encounter was reported to be higher in women compared to men (74.60 % versus 26.62 %) (p?=?0.001).

Conclusion

This study showed notable differences in behaviour patterns between homeless men and women and also indicated that homeless people in Tehran exhibit many risky behaviours.
