Boswellia serrata extract shows cognitive benefits in a double-blind, randomized, placebo-controlled pilot clinical trial in individuals who suffered traumatic brain injury.

BACKGROUND: Traumatic brain injury (TBI) is a major cause of death and disability. TBI can result in neuropsychiatric and cognitive problems as well as neurodegenerative pathologies that can appear right after or develop and persist years after injury. METHOD: We conducted a double-blind, randomized, placebo-controlled clinical trial on patients who suffered from TBI three months to three years ago. The patients were randomized to placebo (n = 34) or K-Vie™ group (n = 46) for a treatment period of 3 months. The main primary outcomes include cognitive assessment in the Rey Auditory Verbal Learning Test-Recognition Test (RAVLT), Wechsler adult intelligence Digit Symbol Substitution Test (DSST) and trail-making test part B (TMT-B). Assessments were performed at baseline and at the month 3 follow-up visit. Linear mixed models were carried out to evaluate cognitive changes from baseline across all cognitive assessment tests. RESULT: The current study showed significant (p < 0.05) improvement in cognitive function of patients who were given K-Vie™ compared with placebo across the RAVLT, DSST and TMT-B performance assessments. A larger cohort would be beneficial to further confirm the clinical utility of K-Vie™ and assess its effects in acute phases of TBI.

Level of attitude toward complementary and alternative medicine among Iranian patients with multiple sclerosis.

BACKGROUND: Multiple sclerosis (MS) is an unpredictable neurological disease leading to severe disability in young adults. The majority of MS patients use complementary and alternative medicine (CAM) as adjunct to conventional therapies. This study aimed to investigate the prevalence of CAM utilization among Iranian patients with MS and their attitude toward the CAM usage. METHODS: A cross-sectional study was conducted on 119 definite MS patients referred to Tehran's Imam Khomeini and Sina hospitals. A questionnaire was used to examine the association between participants' health-related factors and usage of CAMs interventions. P value < 0.05 was considered statistically significant. RESULTS: Among the enrolled patients, 60% of the participants agreed with using CAM, 42% experienced the usage of these treatments; out of whom 41% believed its efficiency and 18% reported exacerbation of symptoms. The mean duration of disease diagnosis and mean time from symptoms onset were both longer in users of CAM (P = 0.001). Most socio-demographic factors had no significant effect on the type of used CAM. However, Yoga was significantly more applied in those with higher degree of education (P = 0.002). CONCLUSION: Regarding the widespread use of CAM by Iranian patients with MS, further researches about the safety and efficacy of each treatment on the special outcomes is recommended.

The new technique of using the epigastric arteries in renal transplantation with multiple renal arteries.

The most common anatomic variant seen in the donor kidneys for renal transplantation is multiple renal arteries (MRA), which can cause an increased risk of complications. We describe the long-term outcomes of 16 years of experience in 76 kidney transplantations with MRAs. In a new reconstruction technique, we remove arterial clamps after anastomosing the donor to the recipient's main renal vessels, which cause backflow from accessory arteries to prevent thrombosis. By this technique, we reduce the ischemic times as well as the operating times. Both in live or cadaver donor kidneys, lower polar arteries were anastomosed to the inferior epigastric artery and upper polar arteries were anastomosed to the superior epigastric arteries. Injection of Papaverine and ablation of sympathic nerves of these arteries dilate and prevent them from post-operative spasm. Follow-up DTPA renal scan in all patients showed good perfusion and function of the transplanted kidney, except two cases of polar arterial thrombosis. Mean creatinine levels during at least two years of follow-up remained acceptable. Patient and graft survival were excellent. No cases of ATN, hypertension, rejection and urologic complications were found. In conclusion, this technique can be safely and successfully utilized for renal transplantation with kidneys having MRAs, and may be associated with a lower complication rate and better graft function compared with the existing techniques.

Does Ramadan fasting has any effects on menstrual cycles?

UNLABELLED:   BACKGROUND: During the month of Ramadan, millions of Muslims abstain from food and drink daily from dawn to sunset and people actually experience repeated cycles of fasting and refeeding. Menstruation is a normal physiological process that its regularity is controlled by hypothalamic-pituitary-ovarian axis. Etiology of menstrual dysfunction includes weight loss, hypoleptinemia, abnormal eating behaviors, exercise, and psychological stressors. OBJECTIVE: To investigate the effects of Ramadan fasting on menstrual cycles. MATERIALS AND METHODS: This analytic cross-sectional study was performed on 80 female college students resident in a dormitory of Hamedan University of Medical Sciences. A questionnaire including demographic characteristics and menstrual calendar was filled by all participants. All analyses were performed using the statistical software SPSS for Windows version 11.5. RESULTS: We found 11.3%, 30%, and 16.3% of participates had abnormal menstrual pattern three months before, during and three months after Ramadan, respectively. In participates who fast more than 15 days, menstrual period had significantly more abnormality than participants who fast less than 15 days. Considering our results we demonstrated that menstrual abnormalities during Ramadan month reach to their peak and three months after Ramadan reduce but do not return to previous condition. CONCLUSION: This study confirms that menstrual abnormalities including oligomenorrhea, polymenorrhea and hypermenorrhea increased during Ramadan especially in participates with more than 15 days of fasting.

Comparison of recombinant human follicle stimulating hormone (rhFSH), human chorionic gonadotropin (HCG) and human menopausal gonadotropin (HMG) on semen parameters after varicocelectomy: a randomized clinical trial.

BACKGROUND: The most frequent physical finding in infertile men is varicocele, in which one of the mechanisms that can affect seminal parameters is oxidative stress. OBJECTIVE: Our study aimed, for the first time, to compare the efficacy of recombinant human follicle-stimulating hormone (rhFSH), human chorionic gonadotropin (HCG) and human menopausal gonadotropin (HMG) on sperm parameters and fertility after varicocelectomy. MATERIALS AND METHODS: 113 infertile men with varicocele were divided into four groups. Group A received HCG 5000 IU weekly, group B received HMG 75 IU three times a week, group C received rhFSH 75 IU three times a week and group D received no medical treatment after varicocelectomy. RESULTS: After three months, in group A sperm morphology improved (p=0.007), causing a 32% pregnancy rate. In group B, sperm motility (p=0.023) and morphology (p=0.014) improved, causing a 57% pregnancy rate. In group C, all of the investigated semen parameters increased (p<0.05), causing a 62.5% pregnancy rate. Only rhFSH improved sperm concentrations to >20×10(6) mL (p=0.027). In group D, sperm morphology increased (p=0.038), but other parameters remained unchanged and no pregnancies occurred. CONCLUSION: It can be concluded that drugs can reduce induction time for spermatogenesis and fertility in comparison with varicocelectomy alone. For these purposes, rhFSH is more effective than other drugs.

Non-Hodgkin's lymphoma in autosomal dominant polycystic kidney disease, 12 years after renal transplantation.

Autosomal dominant polycystic kidney disease (ADPKD) is a systematic disease which accounts for 10-15% of patients receiving dialysis or renal transplantation. It has a statistically significant association with malignancy in renal transplant recipients. We report a 47-year-old ADPKD female who developed a large renal tumor in the right kidney 12 years after kidney transplantation. During the follow-up, her ultrasound and laboratory tests were within normal limits. Bilateral nephrectomy of the native kidneys was performed, and followed by radiotherapy on the right side because pathology of the tumor suggested non-Hodgkin's lymphoma (NHL).

Reconstruction of bladder and urethra using ileocecal segment and appendix in patients with exstrophy-epispadias complex: the first report of a new surgical approach.

OBJECTIVE: We aimed to describe our experience in administering an innovative surgical technique to treat pediatric cases of exstrophy-epispadias complex. MATERIAL AND METHODS: Between 1995 and 2004, seven consecutive patients (six males) with exstrophy-epispadias complex were treated using ileocecal segment for bladder augmentation and appendix for urethral reconstruction. In a single-stage operation, the exstrophied bladder was dissected- and a segment of cecum, ascending colon, terminal ileum, and the corresponding appendix were isolated. Using the opened colon to augment the bladder, the ileal segment was fashioned to skin as temporary stoma, and the appendix was laid in the urethral lumen as the neourethra following urethral demucosation. This technique was used as a secondary surgery in one case and as a primary surgery in six neonates. Evaluation of the urinary tract status was performed by cystograms and ultrasonograms. RESULTS: Renal function was saved in all cases and continence was achieved by clean intermittent catheterization every two hours either via the neourethra (n = 6) or through the temporary stoma (n = 1). The patients did not experience any metabolic complications in their follow-ups. Moreover, no one had vesicourethral reflux, dehiscence, or fistula. CONCLUSIONS: The technique was deemed safe with acceptable outcomes even when secondary repair of previously failed operation was intended. Experiencing the technique in larger cohorts as well as longer follow-ups might be necessary to assess probable long-term complications.

Primary tuberculosis of the glans penis in male kidney transplant recipients: a report on two cases.

An extremely rare form of genitourinary tract tuberculosis (TB) is TB of the glans penis. Here, we report on two men with TB of the glans, both occurring secondary to their wives having genital TB. To the best of our knowledge, this is the first report of this nature from Iran. One case is a 48 year-old blind male with an asymptomatic papulo-pustular eruption over the glans and, the other is a 51 year-old male who had kidney transplantation in March 2004, and was referred to our transplantation clinic nine months later with papulonecrotic ulcer on the glans which did not respond to antibiotic therapy. Both patients responded well to anti-TB treatment. Our cases suggest that every papulonecrotic lesion on the glans must raise the suspicion of TB, and an underlying active or healed focus of TB should be thoroughly searched. Also, it is very important, particularly in endemic areas, that prior to transplanting a male patient, his female partner must be examined for TB of the genitalia.
