Introduction: Sexual dysfunction is common but not often assessed in the routine clinical care among
males on opiate substitute treatment. Objective: To determine the association between clinical variables
and erectile dysfunction (ED) among men on methadone maintenance therapy (MMT). Methods: A
cross-sectional study involving 108 participants who attended the Drug Clinic, Hospital Kuala Lumpur.
The instruments used include the Structured Clinical Interview for DSM-IV Axis-I Disorder (SCID-I),
Beck Depression Inventory (BDI) and International Index of Erectile Function-15 (IIEF-15). Results:
Concurrent heroin abuse was significantly associated with presence of ED (p=0.024). Treatment factors
including methadone dose and duration of methadone treatment were not significantly associated with
ED. Conclusion: Education on sexual dysfunction as a potential adverse effect and its association
with illicit heroin use should be considered in the doctor-patient consultation to encourage treatment
adherence and abstinence from heroin.

To date, the College of Radiology (CoR) does not see any clear benefit in performing whole body screening
computed tomography (CT) examinations in healthy asymptomatic individuals. There are radiation risk issues in CT and principles of screening should be adhered to. There may be a role for targeted cardiac screening CT that derives calcium score, especially for asymptomatic medium-risk individuals and CT colonography when used as part of a strategic programme for colorectal cancer screening in those 50 years and older. However, population based screening CT examinations may become appropriate when evidence emerges regarding a clear benefit for the patient outweighing the associated radiation risks.

Local malaria transmission in the United Arab Emirates (UAE) came to an end in 1997. Nevertheless, UAE has been subjected to substantial importation of malaria cases from abroad, concerning both UAE nationals and immigrants from malarious countries with a total number of 2,119 cases in 2007. To evaluate a new DNA extraction technique using nested PCR, blood samples were collected from 132 individuals who presented to Infectious Diseases Department in Rashid Hospital, Dubai, and Central Department of Malaria Control with fever and persistent headache. Giemsa-stained blood films and ELISA test for malaria antibodies were carried out for detection of Plasmodium infection. Plasmodium infections were identified with the genus-specific primer set and species differentiation using nested PCR. A rapid procedure for diagnosis of malaria infections directly from dried blood spots using for the first time DNA extract from FTA Elute cards was evaluated in contrast to extraction techniques using FTA classic cards and rapid boiling technique. Our new simple technique for DNA extraction using FTA Elute cards was very sensitive giving a sensitivity of 100% compared to 94% using FTA classic cards and 62% in the rapid boiling technique. No complex preparation of blood samples was required prior to the amplification. The production cost of DNA isolation in our PCR assay was much less in comparable to that of other DNA extraction protocols. The nested PCR detected plasmodial infection and could differentiate P. falciparum from P. vivax, and also detected the mixed infection.

INTRODUCTIONGlucocorticoids cause osteoporosis by decreasing bone formation and increasing bone resorption activity. Glucocorticoid action in bones depends on the activity of 11-beta-hydroxysteroid dehydrogenase type 1 (11β-HSD1) enzyme, which plays an important role in regulating corticosteroids. 11β-HSD1 is expressed by human and rat osteoblasts. We aimed to investigate the relationship between 11β-HSD1 dehydrogenase activity and bone histomorphometric changes in glucocorticoid-induced osteoporotic bone in rats.
METHODSA total of 30 male Sprague-Dawley rats (aged three months, weighing 200-250 g) were divided into three groups of ten each. Group 1 rats were the baseline control, which were sacrificed untreated at the beginning of the study. Group 2 rats underwent sham operation and were administered with vehicle olive oil intramuscularly at 0.05 ml/kg. Group 3 rats were adrenalectomised and administered with an intramuscular injection of dexamethasone 120 μg/kg body weight/day. The treatment was started two weeks after the operation, for a duration of two months. Plasma osteocalcin, plasma pyrodinoline, plasma corticosterone and 11β-HSD1 were measured, and bone histomorphometry analysis was performed.
RESULTSDexamethasone treatment caused an increase in plasma corticosterone level, together with a significant reduction in 11β-HSD1 dehydrogenase activity of the bone, along with a higher plasma level of the bone resorption marker, pyridinoline. Dexamethasone treatment also caused a reduction in trabecular volume, number and thickness, and an increase in trabecular separation.
CONCLUSIONLong-term glucocorticoid treatment reduces the 11β-HSD1 dehydrogenase activity in the bone, which can otherwise lead to bone loss due to the increased level of active glucocorticoids.

Tooth avulsion is a dental emergency that needs prompt treatment to minimise complications.
This study aims to evaluate the knowledge and awareness of avulsed tooth management among
dental surgery assistants at the UKM Dental Polyclinic. This survey research design of a 19-
item questionnaire was distributed to 59 dental surgery assistants (DSAs). The questionnaire
consisted of demographic profile questions and questions regarding awareness and knowledge
of tooth avulsion and its immediate management. The results showed that 78% of DSAs at the
Institute know about first aid management of avulsed teeth, with the majority being taught
during their training course. Moreover, 96.2% of the DSAs know what tooth avulsion is and
recognise it as a dental emergency. Although 75% of the DSAs have never previously handled
any avulsed tooth case, 50% are confident in advising the public on what to do with an avulsed
tooth at the time of injury. As for the specific management questions of an avulsed tooth, the
responses from the DSAs varied according to the questions, ranging from 50% to 85%. DSAs
at the Institute have varying levels of awareness and knowledge regarding tooth avulsion.
Therefore, regular education programmes on dental trauma and its management will help
improve the DSAs’ current knowledge and ability to manage avulsion injuries better in
emergencies.

Objective: To investigate the susceptibility to some conventional and non-conventional insecticides in laboratory and field larval populations of the West Nile vector Culex pipiens L. (Cx. pipiens), the dominant species in Jeddah Province, Saudi Arabia. Methods: The tested conventional insecticides were Actikil and Pesgard, while the non-conventional ones were Bacilod, Dudim and Baycidal. Probit analysis and photomicroscopical observations were carried out to shed light on acute toxicity in laboratory and field Cx. pipiens strains. Results: Cx. pipiens were more susceptible to Pesgard (LC

Methods:
In total, 185 lesions were identified on bone and SPECT-CT scans from 32 patients. Lesions were classified as metastatic (109 sclerotic lesions) and benign (76 lesions) morphologically on low-dose CT. Semiquantitative analysis using SUVmax and mean HU was performed on the lesions and compared. To discriminate benign and metastatic lesions, the correlation between SUVmax and mean HU was determined using the intraclass correlation coefficients.
Results:
The SUVmax was higher in metastatic lesions (20.66±14.36) but lower in benign lesions (10.18±12.79) (p<0.001). The mean HU was lower in metastatic lesions (166.62±202.02) but higher in benign lesions (517.65±192.8) (p<0.001). A weak negative correlation was found between the SUVmax and the mean HU for benign lesions, and a weak positive correlation was noted between the SUVmax and the mean HU on malignant lesions with no statistical significance (p=0.394 and 0.312, respectively). The cutoff values obtained were 10.8 for SUVmax (82.6% sensitivity and 84.2% specificity) and 240.86 for the mean HU (98.7% sensitivity and 88.1% specificity) in differentiating benign from malignant bone lesions.
Conclusions
Semiquantitative assessment using SUVmax and HU can complement qualitative analysis. Metastatic lesions had higher SUVmax but lower mean HU than benign lesions, whereas benign lesions demonstrated higher mean HU but lower SUVmax. A weak correlation was found between the SUVmax and the mean HU on malignant and benign lesions. Cutoff values of 10.8 for the SUVmax and 240.86 for the mean HU may differentiate bone metastases from benign lesions.

Toxoplasma gondii (T. gondii) is a zoonotic infection that may be transmitted to human beings either by consumption of raw or uncooked meat or by ingesting oocysts. Toxoplasma organisms can cross blood placenta barrier and may result in congenital toxoplasmosis. About 80% of immunocompetent individuals do not show any clinical manifestations and are silent carriers of this disease. Pregnant women especially in highly prevalent areas are recommended to be screened for this disease in order to prevent the potential vertical transmission. To our knowledge no such study has been conducted in this region of Saudi Arabia. This study attempted to carry out two objectives: first, to find out the seroprevalence of T. gondii infection in pregnant women attending prenatal care services in our hospital; second, to find out risk factors associated with T. gondii seroprevalence in our patients. It was carried out in Teaching Hospital in Al-Kharj over a period of one year. All 306 pregnant women attending antenatal clinic were involved in the study. A pretested selfexplanatory questionnaire was filled out by the patients and their sera were collected to be tested for IgG and/or IgM against T. gondii. The results were then statistically analyzed using SPSS software and p-value was calculated using Pearson Chi Square test. Out of the 306 blood samples tested, 99 (32.4%) were seropositive for specific anti T. gondii IgG antibodies and 3(1%) were seropositive for IgM. This show that seroprevalence of T. gondii antibodies was high among pregnant women and the prevalence showed a significant association with age. The study recommends conducting educational programs to raise awareness among women about risk factors and precautions to be taken.
