Effects of a Cardiac Rehabilitation Program Versus Usual Care on Cardiopulmonary Function in Patients With Cardiac Syndrome X.

PURPOSE: Because of uncertainty in the pathophysiological process, the treatment of cardiac syndrome X (CSX) is still under study. Addressing the effects of cardiac rehabilitation (CR) can help promote the prescription of this modality as an adjuvant therapy for these patients. METHODS: This study was performed on 30 patients with effort-induced angina pectoris using a positive exercise test and/or myocardial perfusion scan in the absence of obvious stenosis or a stenosis of <50% on coronary angiography. The patients were divided into the CR and usual care (UC) groups and underwent cardiopulmonary exercise testing with gas exchange analysis before and after the study. The Duke Treadmill Score was used to compare prognosis and survival estimates of patients. RESULTS: An increase in peak oxygen uptake ((Equation is included in full-text article.)O2) was significantly higher in the CR group than in the control group (P = .017). Resting (Equation is included in full-text article.)O2 was also increased in the CR group, but its difference with the UC group was not statistically significant. Resting O2 pulse was increased in the CR group, which significantly differed between groups (P = .041). Exercise test duration and the Duke Treadmill Score significantly increased in the CR group as compared with the UC group (P = .003 and P = .002, respectively). Also, recovery heart rate in the first minute was significantly improved in CR group. CONCLUSION: Adding a 4-wk course of CR to UC for patients with CSX not only increased the Duke Treadmill Score and exercise test duration but also improved the resting O2 pulse, peak (Equation is included in full-text article.)O2, and first-minute recovery heart rate.

Component Analysis of the Illegal Handmade Pills and Capsules for Self-Medicating Substance Dependence in Tehran, Iran.

BACKGROUND: To self-medicate substance dependence, many substance users consume herbal medicines delivered in herbal medicine shops which are prepared through non-standard methods using a variety of different materials. Hence, the present study was carried out aiming to investigate and analyze the content of such herbal medicines. METHODS: Four herbal medicine shops were selected from each of the 22 zones of Tehran City, Iran, and a total of 95 samples were purchased. A package containing 6 types of medication that was advertised by a satellite TV channel, was also purchased. Using high-performance liquid chromatography (HPLC) method, the samples were analyzed in the laboratory to detect different types of materials. FINDINGS: Among the samples, 23 and 72 samples were uncovered compressed pills (Dragon pills) and capsules filled with colored powders (handmade self-medicating substance dependence capsules), respectively. The package advertised in the satellite TV was prepared in 6 various forms. The most common substances present in all the samples were as follows: diphenoxylate, tramadol, opioids, acetaminophen, and codeine with values of 90%, 86%, 78%, 69%, and 68%, respectively. On average, 5 of the above mentioned substances were present in each sample; moreover, 63% of the samples contained 5 or more substances. In addition, 42 (41%) of the samples contained all the 5 main substances including opioids, codeine, tramadol, diphenoxylate, and acetaminophen. CONCLUSION: The findings of this study showed that handmade capsules and pills used for self-medicating substance dependence and also medicines advertised in the satellite TV channels contain different amounts of opioids, amphetamine, benzodiazepines, tramadol, codeine, and other substances that cause problems for substance users who are going to abandon substance abuse.

The effect of plasmapheresis on treating disseminated intravascular coagulation (DIC) caused by a Hemiscorpius lepturus (Gadim) sting.

INTRODUCTION: The highest mortality from scorpion stings in Iran is due to the stings of a particular type of scorpion known as Hemiscorpius lepturus (H. lepturus, Gadim in local language). The present study aimed at investigating the use of plasmapheresis to treat severe cases of H. lepturus stings. METHOD: This pilot study was a randomized clinical trial conducted from June 2015 to June 2016 in Razi hospital of Ahvaz, Iran. Twenty-nine patients who had been stung by H. lepturus and admitted to ICU because of disseminated intravascular coagulation (DIC) were randomly assigned into control (15 patients, supportive treatments) and plasmapheresis (14 patients, supportive treatments + plasmapheresis) groups, and the patient outcomes were compared between the two groups. FINDINGS: Eighteen patients were female (62%), and the mean of patient age was 24 ± 7. Most of the sting cases had occurred in the torso (15 patients, 52%). Only 10 patients (34%) arrived in the hospital within 12 h of being stung. There was no significant difference between the two groups in terms of the demographic and sting features. In the plasmapheresis group, hemoglobin level was significantly lower, while the PT and INR were measurably higher. In total, the plasmapheresis group experienced 29 sessions of treatment (an average of two sessions for each patient). Overall, 19 patients (66%) expired, whereas 10 patients (34%) experienced recovery with or without complications. The rate of recovery was significantly higher in the plasmapheresis group compared with controls, with eight patients (57%) in the plasmapheresis group surviving compared with two (14%) in the control group (p=.045). The duration of hospitalization was higher in the plasmaphersis group (p < .001). A comparison of the dead and recovered patients' features indicated that the dead patients arrived in the hospital significantly later than the recovered ones, and they also had lower platelet counts. CONCLUSIONS: The findings of this small-scale pilot study show that using plasmapheresis in treating DIC in patients stung by H. lepturus can prevent death and encourage recovery. However, prior to using plasmapheresis as a routine treatment for severe cases of people stung by this scorpion or other similar ones, further controlled studies with a larger sample size are needed.

Evaluation of blood lead level in methamphetamine users in Tehran.

BACKGROUND: Given the increasing number of lead poisoning in opioids users and since no study has been conducted so far to review lead poisoning in methamphetamine (crystal) users, this study aimed to investigate blood lead level in methamphetamine addicts. METHODS: This study was conducted on 20 patients with methamphetamine poisoning and their blood lead level was measured. The subjects were selected from among patients with a history of continuous use of methamphetamine, without a history of using opiates in the past 6 months confirmed by a negative urine tests, and without a history of heavy metal poisoning. RESULTS: Of all, 18 patients were male and the mean age was 32 ± 10 years; 17 patients were abusing the drug via inhalation and three persons via oral administration. The mean blood lead level was 2.3 ± 1.1 µg/dL and poisoning was not observed in any of the cases. Blood lead level was not associated with age, sex, dosage, and route of administration. CONCLUSION: Although blood lead level was not at poisoning level in people who only used methamphetamine in Iran, due to the simultaneous use of other substances and because of non-specific symptoms, lead poisoning must be suspected in all cases of substances poisoning.

Comparison of the Effects of Lidocaine Prilocaine Cream (EMLA) and Lidocaine Injection on Reduction of Perineal Pain During Perineum Repair in Normal Vaginal Delivery.

OBJECTIVE: To compare the efficacy of EMLA cream and lidocaine injection to reduce pain during episiotomy repair. MATERIALS AND METHODS: A total of 46 primiparous women with normal pregnancy who referred for normal vaginal delivery and needed episiotomy repair were selected and randomly divided into two groups. For EMLA group, one hour before the estimated time of delivery, 5g of EMLA cream was applied to perinealmediolateral incision, and after the delivery of the fetus and placenta, again 5g of EMLA cream was applied to healthy skin around the episiotomy for repair. In the other group, lidocaine 2% was used before episiotomy and for its repair, too. RESULTS: Only 8 people (19%) were in need of further analgesia. The mean ± SD of pain during repair of episiotomy on the VAS scale in all cases was 4.2 ± 2.3 cm. Most people (97%) were satisfied with their episiotomy repair. Comparing the two groups of EMLA and lidocaine, there was no difference between the two groups in terms of the duration of episiotomy repair, need for further analgesia, pain on the VAS scale, and satisfaction with the repair method. CONCLUSION: The findings of this study showed that the use of EMLA cream in the site of episiotomy incision in primiparous women can induce a level of analgesia equal to that of lidocaine, and cause a similar level of satisfaction.

Evaluation of anxiety and depression among female spouses of Iranian male drug dependents.

BACKGROUND: Existing evidences suggest the more vulnerability of spouses of drug dependents, in exposure to mental disorders. OBJECTIVES: This study aimed to evaluate the associated parameters of anxiety and depression among female spouses of male drug dependents. PATIENTS AND METHODS: With a cross-sectional design in 2010, a total of 237 Iranian women were selected and divided into three groups: 1. non-drug-dependent wives who had non-drug-dependent husbands (Group I), 2. non-drug-dependent wives who had drug-dependent husbands (Group II), and 3. drug-dependent wives who had drug-dependent husbands (Group III). Socio-demographic characteristics were collected by a checklist, and the levels of anxiety and depression were measured through the Hospital Anxiety and Depression Scale (HADS). Linear regression was applied for determination of anxiety and depression predictors. RESULTS: Mean age of the participants was about 35 years, and mean duration of marriage was 14 years. Drug dependence of the husband (P = 0.010) and lower monthly income of the family (P = 0.007) predicted the higher level of anxiety among the participants, while older age (P = 0.031), shorter marital duration (P = 0.016), and lower educational level (P = 0.045) in addition to spousal drug dependence (P = 0.023), and lower family income (P = 0.014) were significantly associated with higher levels of depression. CONCLUSIONS: Findings of the present study demonstrate that spousal drug dependence and lower monthly income were common predictors of anxiety and depression among spouses of drug dependents in Iran, while older age, shorter marital duration and lower educational level were predictors of depression. However, more research is needed to find casual relationships between spousal drug dependence and mental health in Iran.

Characteristics of drug demand reduction structures in Britain and Iran.

Administrative structure of drug demand reduction and the way in which involved organizations interact with each other has been neglected by researchers, policy makers, and administrators at the national level and even in international institutions in this field. Studying such structures in different countries can reveal their attributes and features. In this study, key experts from the addictive behavior department of St George's University of London and a group of Iranian specialists in the field of drug demand reduction first wrote on a sheet the name of organizations that are in charge of drug demand reduction. Then, via teamwork, they drew the connections between the organizations and compared the two charts to assess the relations between the member organizations. In total, 17 features of efficient structure were obtained as follow: multi-institutional nature, collaborative inter-institutional activities, clear and relevant inter-institutional and intra-institutional job description, the ability to share the experiences, virtual institutions activity, community-based associations activity, mutual relationships, the existence of feedback sys-tems, evaluation, changeability, the ability to collect data rapidly, being rooted in community, flexibility at the local and regional levels, connection with research centers, updated policymaking, empowering the local level, and seeking the maximum benefit and the minimum resources. Recognizing the characteristics of substance related organizations in various countries could help policy makers to improve drug demand reduction structures and to manage the wide-spread use of psychoactive substances more effectively.

Component analysis of Iranian crack; a newly abused narcotic substance in iran.

Iranian crack is a new form of narcotic substance that has found widespread prevalence in Iran in the past years. Crack only nominally resembles crack cocaine as it is widely different in its clinical signs. Thus the present study aims to quantify the chemical combination of this drug. The samples included 18 specimen of Crack collected from different zones of Tehran, Iran. All specimens were in the form of inodorous cream solid powdery substance. TLC and HPLC methods were used to perform semi-quantitative and quantitative analysis of the components, respectively. The TLC analysis showed no cocaine compound in the specimens while they all revealed to contain heroin, codeine, morphine and caffeine. All but two specimens contained thebaine. None of the specimens contained amphetamine, benzodiazepines, tricyclic antidepressants, aspirin, barbiturates, tramadol and buprenorphine. Acetaminophen was found in four specimens. HPLC revealed heroin to be the foundation substance in all specimens and most of them contained a significant amount of acetylcodeine. The present analysis of the chemical combination of Crack showed that this substance is a heroin-based narcotic which is basically different from the cocaine-based crack used in Western countries. Studies like the present one at different time points, especially when abnormal clinical signs are detected, can reveal the chemical combination of the target substance and contribute to the clinical management of its acute or chronic poisoning.

Risk factors of suicidal ideation and attempt in women with drug user spouses.

BACKGROUND: Despite ample evidence of the presence of mental and psychological disorders observed in the family members of drug users, few studies have attempted to focus on suicidal behavior in women whose spouses are drug users. METHODS: This cross-sectional study focused on 131 women who had a drug user spouse. They had all been married for >2 years, with no mental or psychological disorders and no history of drug use prior to marriage. Drug use history after marriage, the extent and nature of physical and non-physical wife abuse, and any history of suicidal ideation and attempt in the past year were collected, in addition to data about anxiety and depression. RESULTS: Our study showed that women who identified with a history of suicidal ideation and attempt were younger, had a shorter marital duration, had a more extensive history of drug use, were more likely to be abused by their spouse, and had higher anxiety and depression scores than their counterparts. Suicidal ideation predictors included a personal history of drug use [odds ratio (OR) = 9.217, 95% confidence interval (CI) = 1.727-49.180, p = 0.009] and anxiety and depression (OR = 1.080, 95% CI = 1.022-1.141, p = 0.004), whereas suicidal attempt predictors included a personal history of drug use (OR = 7.236, 95% CI = 1.671-31.326, p = 0.010), exposure to physical abuse by spouse (OR = 4.005, 95% CI = 1.393-11.523, p = 0.008), and anxiety and depression (OR = 1.092, 95% CI = 1.015-1.175, p = 0.018). CONCLUSION: The findings of this study showed that a personal history of drug use, an elevated anxiety score, and depression and exposure to physical abuse by their spouse may act as predictors of suicidal ideation or attempt in women with a drug user spouse. These findings may serve to benefit and support healthcare systems, associated with ongoing efforts to develop preventive programs for suicidal behavior in this population.

The effect of opium dependency on testis volume: a case-control study.

BACKGROUND: Given the paucity of data on possible testis changes in opioid dependents, we sought to compare the testis volumes between a group of opium dependents and a group of healthy controls. OBJECTIVE: Comparison of testis volume between opium dependents and healthy controls. MATERIALS AND METHODS: This case-control study recruited 100 men with opium dependency (cases) and 100 healthy men (controls) in Iran, in 2008. A checklist containing questions about age, height, weight, daily amount of cigarette use, and duration of cigarette use for all the participants as well as daily amount of opium use (grams) and duration of opium use (years) for the case group was completed. Additionally, the dimensions of each testis were measured by a single person using calipers, and the mean of the left and right testes volume was compared between these two groups. RESULTS: The mean of the testis volumes in the case group was significantly lower than that of the case group (11.2±2.2 and 25.1±2.7cm³, p<0.001). The results of the ANCOVA test showed that even after the omission of the cigarette smoking effect (p=0.454), the testis volume remained lower in the opium dependents (R(2)=0.884, p<0.001). In the case group, there were significant reverse correlations between testis volume and age (r=-0.404, p<0.001), daily amount of opium use (r=-0/207, p=0.039) and duration of opium use (r=-0.421, p<0.001). CONCLUSION: We found that the testis volume in the male opium dependents was lower than that of the healthy controls. We would recommend that future studies into the impact of drugs on the testis dimensions pay heed to possible histological changes in the testes owing to opium dependency.

Initiation to the first drug use among substance-dependent persons in Iran.

In the present study, we report the initiation to the first drug in a representative sample of drug dependents in Iran. This is a cross-sectional study with a sample size of 7,743. The participants were characterized as drug dependents according to the Diagnostic and Statistical Manual-Fourth Edition and were sampled from the medical centers, prisons, and streets of the capitals of 29 provinces in the Islamic Republic of Iran. The mean age at first drug use in the sample was 21.1 (6.5), which differed for various first drugs of abuse. Opium was the first drug of use among 46.4% of the sample, and cannabis was the first drug only among 23.5%. The most frequent place of initiation was at a friend's house (n = 2,476, 33.2%). The same-gender friend out of school (the highest rate) was the most frequent person who suggested the first use. A total of 43.5% of the participants started drug use with friends and 18.8% at a friend's party. Policymakers may benefit from considering the information provided here in designing programs with the purpose of prevention.

Marital adjustment in patients on long-term hemodialysis: a case-control study.

INTRODUCTION: This study was conducted to compare marital adjustment between patients on long-term hemodialysis and healthy controls and to determine whether the psychological symptoms correlate with marital adjustment in these patients. MATERIALS AND METHODS: In a case-control study, 40 patients on long-term hemodialysis and 40 healthy participants were compared for the quality of marital relationship. The Revised Dyadic Adjustment Scale was used for interviews of marital relationship, which includes total marital adjustment and its subscales of marital consensus, affection expression, marital satisfaction, and marital cohesion. Symptoms of anxiety and depression and the Ifudu comorbidity scale were also assessed in the patients group. RESULTS: Marital consensus, affection expression, marital satisfaction, marital cohesion, and the overall marital relationship were significantly poorer in the patients on hemodialysis than in the controls. Also, symptoms of anxiety were more severe among the patients on hemodialysis in comparison with that in the controls. However, this was not the case for symptoms of depression. In the patients on hemodialysis, the severity of anxiety slightly correlated reversely with the total marital relationship score and marital satisfaction subscale. Depression correlated reversely with total marital adjustment, affection expression, marital satisfaction, and marital cohesion. Finally, some marital relationship subscales showed poorer results in men on dialysis, younger patients, and those with higher educational levels. CONCLUSIONS: Marital adjustment in patients on hemodialysis, which is linked with depressive symptoms and anxiety, is poorer compared to the healthy controls. This finding shows the necessity of an appropriate family approach for patients on long-term dialysis.

Urogenital history in veterans exposed to high-dose sulfur mustard: a preliminary study of self-reported data.

INTRODUCTION: To date, little information exists regarding urogenital diseases in those who have been exposed to sulfur mustard (SM). We report the self-reported history of urologic conditions and findings on physical examination in a group of male veterans 19 to 26 years after exposed to high-dose sulfur mustard. MATERIALS AND METHODS: Data on urologic health conditions of a nationwide health survey were used in this study. This survey included all 289 Iranian male veterans who had been exposed to high doses of SM between 1983 and 1989. Demographic data, exposure-related data, health status, and also self-reported lifetime history of urologic conditions were analyzed. History of benign prostatic hyperplasia, recurrent urinary tract infections, pyelonephritis, urinary calculi, kidney failure, and urogenital neoplasms were specifically concerned. RESULTS: The mean age of the veterans was 45.0 ? 7.5 years (range, 30 to 75 years). An interval of 19 to 26 years had passed from exposure to SM. Fifty veterans (17.3%) had a positive history of urinary calculi, 25 (8.7%) had recurrent urinary tract infections, 5 (1.7%) had BPH, and 2 (0.7%) had kidney failure. None of them had experienced urogenital malignancies. Neither recurrent urinary tract infections nor urinary calculi were significantly associated with age, medications and their doses, or SM-induced late complications in other organs. CONCLUSION: This study adds the prevalence of self-reported urologic conditions to our limited knowledge on SM-exposed veterans' health condition, without finding any link neither to demographic, nor to the severity of health complications related to the SM exposure.

Marital relationship and its correlates in kidney recipients.

Marital discordance is known to be associated with morbidity and mortality in chronically ill patients, but its correlates have yet to be fully addressed in renal recipients. The aim of this study was to assess marital relationship and its correlation with patients' morbidity after kidney transplantation. Ninety-three married Iranian kidney recipients who had undergone kidney transplantation in Baqiyatallah Hospital, Tehran, Iran, were assessed for marital adjustment with the Revised Dyadic Adjustment Scale (RDAS). The patients' quality of life (Short From-36), anxiety and depression (Hospital Anxiety and Depression Scale), and sexual relationship (Relationship and Sexuality Scale) were also evaluated. Eighty-seven subjects (93.5%) completed our study. The mean (SD) of RDAS was 52.9 (9.7). RDAS score showed a significant correlation with anxiety symptoms, frequency of intercourse and quality of life (p < 0.05). Also, RDAS score was poorer in recipients with low education level, low family income and positive history of graft rejection (p < 0.05). RDAS score was not significantly associated with gender, occupation, age at transplantation time, transplant-to-rejection time interval, source of graft, cause and duration of end-stage renal disease and depression (p > 0.05). Transplantation medical teams should refer patients to psychologists and/or psychiatrists for marital satisfaction consultation before kidney transplantation. This is of great significance especially in those with older ages, lower levels of education and lower income. Marital discord may also be considered as a cause or an effect of an unsatisfactory sexual relationship, higher anxiety or lower quality of life after kidney transplantation.

Sexual function: a comparison between male renal transplant recipients and hemodialysis patients.

INTRODUCTION: For all the studies into the sexual health of kidney transplant recipients, there is a paucity of controlled studies regarding the difference in the sexual relationship of kidney transplant recipients and end-stage renal disease (ESRD) patients under hemodialysis. AIM: We compared the sexual function of kidney transplant recipients and ESRD patients under hemodialysis in male patients. MAIN OUTCOME MEASURES: The patients' sexual function was assessed using the Relationship and Sexuality Scale. METHOD: In this case-controlled study, 89 male renal transplant recipients and 25 male hemodialysis patients were randomly selected from the outpatient clinic of Baqiyatallah Hospital, Tehran, Iran, in 2006. The two groups were not significantly different in terms of age, living place, level of education, duration of ESRD (months), ESRD cause, and somatic comorbidities (Ifudu index). RESULTS: The renal transplant patients in comparison with the hemodialysis group reported a better overall sexual relationship (17.3 +/- 0.6 vs. 21.6 +/- 1.4; P = 0.001), and all subscales including sexual function (9.9 +/- 0.3 vs. 11.4 +/- 0.6; P = 0.03), sexual frequency (6.3 +/- 0.3 vs. 7.4 +/- 0.6; P = 0.04), and sexual fear (1.1 +/- 0.2 vs. 2.8 +/- 0.5; P = 0.001). In addition, kidney recipients had significantly more sexual intercourse in a 2-week period prior to the study (P = 0.008). CONCLUSIONS: In our male population, kidney transplant recipients, in comparison with the ESRD patients under hemodialysis, reported a better sexual relationship.

Prophylactic ophthalmic bethametazone for sulfur mustard-induced ocular injury.

BACKGROUND: The present study sought to evaluate the prophylactic effect of bethametazone on sulfur mustard (SM)-induced ocular morphometric damage in the rabbit eye. METHODS: Twenty five healthy New Zealand white rabbits were divided into 4 groups of normal (not exposed to SM or solution), solution (exposed to solution), SM (exposed to SM), and prophylactic bethametazone (received eye solution of bethametazone then exposed to SM solution; then treated for 2 weeks). On the day 14 after exposure, five-micron sections were stained with haematoxylin and eosin for light microscopy evaluation. The ocular morphometric characteristics in the study groups were compared to determine the prophylactic effects of the bethametazone. RESULTS: Bethamethazone could protect eyes from SM effect by means of decrease in changes in number of Keratocyte in 10000 µm(2), thickness of cornea (µm), thickness of corneal epithelium (µm), number of meibomian gland's cells in 2500 µm(2), thickness of palpebral conjuctival epithelium (µm), thickness of epithelial of palpebral skin (µm), number of epithelial layers of palpebral skin, and number of goblet cells in conjunctival sac in 1000 µm. CONCLUSIONS: Bethametazone may have a prophylactic effect on the early lesions of the eye of the rabbit due to SM exposure.

Mucormycosis after kidney transplantations: report of seven cases.

This is a report of 7 cases of mucormycosis infections in patients who had undergone transplantation and been admitted in the kidney transplant centre of Baqiyatallah Hospital in Tehran, Iran, from 2002 to 2005. We retrospectively reviewed the hospital records for demographic data, symptoms, diagnostic techniques and outcomes. Five patients were male and 2 female. The mean age of patients was 49.5 y. The time interval between transplantation and disease onset varied greatly (range: 1 month to 4 y). Patients' symptoms were fever (7 cases), respiratory distress (4 cases) and severe headache (3 cases). Suspected patients were evaluated by CT scan, BAL and biopsy and diagnosis confirmed by culture. The final diagnosis was pulmonary mucormycosis in 4 cases, rhino-cerebral mucormycosis in 2 cases and disseminated mucormycosis in 1 case. Despite early and intensive treatment with amphotericin B in all patients and extensive debridement in 3 cases, only 2 patients survived the disease. Mucormycosis is a potentially lethal complication after kidney transplantation. It could occur very early on or very late into the post-transplant period. Despite the results of other studies, the most frequent site of infection in our patients was the lungs.
