AIM:To compare the efficacy of intravitreal triamcino-lone acetonide and conventional treatment for macular edema in retinal vein occlusion.METHODS:In this clinical study 21 patients were enrolled with macular edema due to retinal vein occlu-sion. Prior to treatment, all patients underwent an exten-sive ophthalmic examination. Patients were divided randomly into two groups. Nine patients were treated with 4mg intravitreal triamcinolone acetonide (Kenalog) and 12 patients underwent conventional treatment.RESULTS: Before treatment, logMAR (logarithm minimum angle resolution) visual acuity in conventional treatment was 1.20±0.38 and in Kenalog group it was 1.64±0.31. One month after treatment, the visual acuity was improved to 0.98±0.54 in conventional treatment group and 0.87±0.61 in Kenalog group. There was a significant difference in visual acuity improvement between conventional treatment group and Kenalog group (0.22 vs 0.76) (P=0.01).CONCLUSION:Our results showed that although visual acuity improvement was seen in both groups but Kenalog was more effective than conventional treatment in macular edema due to retinal vein occlusion.

Mediastinal mature cycstic teratomas are rare germ cell tumors most commonly found in the anterior mediastinum, and constitute about 3-12% of all mediastinal tumors. They growslowly and are usually diagnosed incidentally. This is a rare presentation of a young lady with mediastinalmature cystic teratoma (dermoid cyst) presenting with chronic cough and haemoptysis.

Objective: To report a case of neuroleptic malignant syndrome (NMS), secondary to low dose quetiapine in an elderly Iranian man. Methods: We report a 66-year-old male presented with a temperature of 39.30c, dysphagia, aphasia and decreased level of consciousness and mutism following the use of 25 mg quetiapine. Results: Some evidence suggests an atypical NMS presentation with the atypical antipsychotics. Atypical NMS has been defined as less severe than that seen with conventional antipsychotics. Symptoms include fewer EPS, smaller increases in CK, less muscle rigidity, and lower fever. Conclusion: Clinicians should be aware that NMS with a single dose of quetiapine is possible.

Erectile dysfunction is one of the most common side effects of methadone affecting more than half of methadone patient population. The problem is associated with prominent reduced quality of life. Erectile dysfunction may perpetuate greater problem if left untreated as patients may opt to use harmful self-treatment such as abusing methamphetamine. This illicit drug use to overcome the side-effects of methadone may lead to polysubstance use disorder that further compromise addiction therapy. To overcome this issue, both practitioners and patients play a major role in the management of erectile dysfunction. Patient awareness regarding erectile dysfunction and its impact as well as doctor’s active intervention to detect erectile dysfunction, are essential to improve the detection rate and management of erectile dysfunction. Frequent screening of erectile dysfunction and its risk factors will help with the identification of patients suffering from erectile dysfunction. Multiple treatments options such as bupropion, trazodone and many more are available to treat erectile dysfunction which will be further explored in this review.

Vaginal atrophy is one of the most common menopausal complications and is often overlooked. There are various pharmacological and non-pharmacological treatment approaches to reduce vaginal atrophy; however, no comprehensive study on a convenient, affordable, inexpensive, and noninvasive treatment with fewer complications has been conducted so far. Thus, the current study aimed to provide a systematic review of pharmacological treatment for vaginal atrophy in postmenopausal women in Iran. In this systematic review, all Iranian articles published in Persian or English during 2009 to 2019 were collected and analyzed by searching the Scopus, PubMed, Web of Science, Magiran, Iranian Registry of Clinical Trials (IRCT), and Cochrane Library databases. The inclusion criteria were clinical trials for vaginal atrophy and menopause. Based on the selection criteria, articles with a Jadad scale score of 3 and above were included in the study and qualitatively analyzed. Overall, 15 clinical trials met the inclusion criteria. In total, 12 articles examined the efficacy of pharmacological treatments (including three herbal medicines, three vitamins and dietary supplements, and two chemical drugs) in treating vaginal atrophy in postmenopausal women. Various types of medication have been used to improve vaginal atrophy, and effective treatments include licorice, chamomile, royal jelly, vitamin E, vitamin D, hyaluronic acid, and Vagifem; however, the results of studies on fennel have been inconsistent. However, considering the small number of studies reviewed, further studies with a stronger methodology are needed to confirm the efficacy of these medications.

According to the class of hypovolaemic shock, a blood loss less than 750 ml is not associated with the physiological changes. As a result it may cause a delay in fluid resuscitation. We postulate inferior vena cava (IVC) diameter reduction in inspiration and expiration may resemble the significant volume of blood loss in a healthy adult. We conducted a study to examine the changes of the IVC diameter pre and post blood donation.The inferior vena cava diameter during inspiration (IVCi) and expiration (IVCe) were measured using ultrasound (GE HEALTH) in supine position before and after blood donation of 450 ml. Paired t-test and Wilcoxin rank test were used to analyse the data. Forty two blood donors enrolled during the study period. The mean age of blood donors was 32.3 +/- 8.9 and mainly male blood donors. The mean IVCe of pre and post blood donation was 18.5 +/- 6.2 mm (95%CI 18.23, 18.74) and 16.6 +/- 6.6 mm (95%CI 16.35, 16.76) respectively. Meanwhile, the mean IVCi of pre and post blood donation was 17.1 +/- 8.6 mm (95%CI 16.89,17.30) and 15.6 +/- 6.6 mm (95%CI 15.43,15.81) respectively. The mean difference of IVCe pre and post blood donation was 1.9 +/- 0.5 mm (95%CI 1.75, 2.13) (p<0.001). In contrast, the mean difference of IVCi pre and post blood donation was 1.5 +/- 0.5 mm (95%CI 1.34, 1.68) (p<0.001). As a conclusion, the measurement of IVC diameter by ultrasound can predict the volume of blood loss in simulated type 1 hypovolaemia patient.

Theophylline toxicity is a life-threatening toxidrome that can present to an emergency department. To ascertain an immediate provisional diagnosis in toxicology at the emergency department is very challenging, especially when the patient presents with altered mental status, because the clinical features of several toxidromes overlap. We report a case of survival of undiagnosed theophylline toxicity that required intubation for two days in the intensive care unit. This was the first case to have been reported from our department. Accurate diagnosis of a toxidrome by gaining adequate history and conducting a thorough physical examination and early serum toxicology screening, coupled with good knowledge of toxicology, will lead to better patient outcomes.

Since 1978, Rohingya refugees have fled from their native nation, Myanmar to escape ethnic prosecution. They comprise of the Muslim minority ethnic group originating from the Rakhine state in Myanmar. In many host countries, they may have difficulty to access health care services. The Islamic Association of Malaysia (IMAM) Response and Relief Team (IMARET) have taken many initiatives to provide healthcare services to the refugees through their volunteer-led mobile clinics. Therefore, this study aims to evaluate the utilisation of drugs among type 2 diabetes mellitus (T2DM) patients visiting this clinic. Methods: This was a cross-sectional study among Rohingya refugees with T2DM that visited the IMARET mobile clinics from August until November 2017. Convenient sampling method was used. Data were collected through patient’s interview, review of the patient’s prescriptions and their HbA1c readings. Results: A total of 29 T2DM patients were included in this study. The majority were female (75.9%) and aged below 65 years old (75.9%). The most commonly prescribed anti-diabetic agent was metformin (72.2%), followed by glibenclamide (22.2%) and gliclazide (5.6%). Metformin as a monotherapy (31%) was the most frequent treatment prescribed. More patients had controlled T2DM (62.1%) compared to those with uncontrolled DM. We found 90.9% of patients who were treated according to the recommended DM guidelines achieved a good blood glucose control (p=0.02). Conclusion: In Rohingya refugees having T2DM who were treated in the IMARET mobile clinic, the percentage having good control DM status is higher in those whose treatment regimen adheres to the clinical practice guidelines.

PURPOSE: Breast cancer is the most common type of cancer in women. Despite various pharmacological developments, the identification of new therapies is still required for treating breast cancer. Crab is often recommended as a traditional medicine for cancer. This study aimed to determine the in vitro effect of a hydroalcoholic crab shell extract on a breast cancer cell line. METHODS: In this experimental study, MCF7 breast cancer cell line was used. Crab shell was powdered and a hydroalcoholic (70degrees ethanol) extract was prepared. Five concentrations (100, 200, 400, 800, and 1,000 microg/mL) were added to the cells for three periods, 24, 48, and 72 hours. The viability of the cells were evaluated using trypan blue and 3-(4, 5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assays. Cell apoptosis was determined using the terminal deoxynucleotidyl transferase dUTP nick end labeling method. Nitric oxide (NO) level was assessed using the Griess method. Data were analyzed using analysis of variance, and p<0.05 was considered significant. RESULTS: Cell viability decreased depending on dose and time, and was significantly different in the groups that were treated with 400, 800, and 1,000 microg/mL doses compared to that in the control group (p<0.001). Increasing the dose significantly increased apoptosis (p<0.001). NO secretion from MCF7 cells significantly decreased in response to different concentrations of the extract in a dose- and time-dependent manner (p<0.050). CONCLUSION: The crab shell extract inhibited the proliferation of MCF7 cells by increasing apoptosis and decreasing NO production.
