Aniqa Kiran, Muhammad Junaid Ijaz, Muhammad Mustafa Qamar, Ayesha Basharat, Akhtar Rasul, Waqas Ahmed
January-June 2018, 3(1):26-30
Objective: The objective of this study is to determine the outcome and efficacy of Mulligan's mobilization with movement (MWM) with Maitland mobilization along with conventional therapy in the patients with knee osteoarthritis (OA). Materials and Methods: A randomized controlled trial study was performed at the Department of Physiotherapy, Mayo Hospital, Lahore, Pakistan. Sixty-two patients were selected for the study. MWM was introduced in half of the patients and Maitland mobilizations in the second half for 2 weeks. The goniometry, visual analog scale (VAS), knee range of motion (ROM), and Western Ontario McMaster OA (WOMAC) Index for knee OA were the assessment tools used to assess all patients before and after 2 weeks of intervention. Paired sample t-test was used for analysis of results. Results: The mean pre- and postdifferences in MWM group were 4.06 ± 0.99, 10.19 ± 3.87, and 19.41 ± 7.58 for VAS, ROM flexion, and WOMAC Index, respectively, while the pre- and postmean difference values for Maitland mobilization group were 3.355 ± 1.05, 10.19 ± 5.5, and 12.28 ± 7.029 for VAS, ROM flexion, and WOMAC Index, respectively. The mean differences of both treatment interventions individually were significant and showed that both were clinically effective in treating the patients of knee OA. Conclusion: It was concluded that patients in both groups showed improvement in pain, ROM, and functions.

Tauwfik Mohamed Salih, Idris Mohamed El-Mahdi
July-December 2018, 3(2):42-48
Aims: The aim of this work is to “predict” the remaining shelf-life of chloramphenicol (CH) eye drops, commercially marketed, using the theoretical “Longland–Rowbotham model,”” followed by confirmation of findings by practical means. Materials and Methods: The methods used for the evaluation of CH-eye drops included the assay of the active ingredient, sterility testing, and minimum inhibitory concentration (MIC) determination using official methods during 6 months stability study at variable temperatures (4, 25°C). Furthermore, a 3-month accelerated stability study was carried out. Statistical analysis tests included Student's t-test and analysis of variance. Results: The prediction model indicated that in pessimistic conditions, the remaining shelf life was reduced to a merely 1 month following production (this is versus the 2 years expiration date given by manufacturer). However, the samples analyzed throughout a 6-month stability study revealed that storing CH solution at 4°C or 25°C does not produce any statistical difference regarding drug content, MIC, or sterility. Accelerated stability studies for 3 months period showed that only after 2 months from storage at 55°C the drug will start to degrade and a statistical difference could be observed. Conclusion: Storing CH-eye drops at room temperature for up to 6 months appears to have no effect on the stability of this antibiotic.

Introduction: Cosmetics have been utilized by most of the people irrespective of their race, gender, or age to beautify, modify, or improve the physical appearance. Many cosmetic products contain heavy metals as ingredients or impurities. Recent research has reported that these metals can cause many types of health and skin problems. Aims: The aim of this study is to detect the levels of heavy metals in some cosmetic products that are available in cosmetic shops around the city of Benghazi. Materials and Methods: Twenty-five of cheap facial cosmetic products that are widely in demand in cosmetic shops in Benghazi were collected in April 2016. The samples included eight kohl, seven eyeliners, and ten lipsticks. Metals including iron, copper, chromium, zinc, lead, and cadmium were analyzed in the selected samples using flame atomic absorption spectrophotometer after suitable digestion process. Results: Our results indicated that iron and copper were detected in all samples with concentration ranges varying from 0.5 to 124.5 mg/kg for iron and 1.8–51.4 mg/kg for copper. The concentration ranges of chromium, zinc, cadmium, and lead were varied from 0.0 to 7.25 mg/kg, 0.0 to 22.75, 0.0 to 125.0 mg/kg, and 0.0 to 20.25 mg/kg, respectively. Conclusions: The results showed that the selected metals were detected in most of the samples at varying concentrations. Kohl samples have the highest concentration of the analyzed metals. According to the maximum allowed limits recommended by the World Health Organization (WHO) for toxic metals in cosmetics, there was only one sample that had lead concentration higher than the maximum limit recommended by the WHO. In addition, there were twenty samples that had concentrations of cadmium above the WHO legislation limits.

MHS Ahmeda, NHS Ahmida, AA Ahmeida
January-June 2017, 2(1):12-26
Nanotechnology is an emerging multidisciplinary technique that involves application based on the synthesis of molecules in nano-scale size range. Nanotechnology is also seen as new and fast emerging field that involves the manufacture, processing and application of structure, device and system by controlling shape and size in nanometer scale. The concept of nanotechnology is driven from the Greek word nano (meaning dwarf). The nano-particles are defined as a discrete entity that has dimensions of the order of 100 nm or less. It is the small size in combination with the chemical composition and surface structure that gives the nano-particles their unique features. The alterations in physical properties serve to enhance versatility and efficacy in product development, resulting in more effective industrial and medical applications. As a result of the widespread use of nanotechnology and nano-materials, these particles find their way into the environment. Therefore, a focus on the source of nano-particles in the environment and their effects is included. This review concentrate on the recent information about analytical developments to assess the occurrence, fate and behavior of nano-materials in environment. It also focuses on the applications of nanotechnology in environment, especially in the area of air and water purifications.

Medical education in Libya: Challenges, hopes, and recommendations
Arif Al-Areibi
January-June 2019, 4(1):3-9
The purpose of this review is to examine the current Libyan medical education system, look at its positive and negative aspects, and to provide suggestions and recommendations that could help improve the quality of the system today. The current Libyan medical education system has aged, and unfortunately, cannot meet both societal needs and the new requirements from the World Federation of Medical Education (WFME). The WFME issued a strong statement to all international medical schools to meet its new accreditation standards by 2023 in order for them to be recognized internationally. Lacking almost 70% of the international standards, Libyan medical schools will require considerable amount of time and resources to solve the issue. The process of changing and updating the system will involve all parts of the learning environment, including students, teachers, curriculums, resources, research, and governing bodies.

Nada Kashbur, Iman Bugaighis
January-June 2019, 4(1):26-32
Aims: The aims of the present study were to evaluate the level of Libyan patients' expectations of and satisfaction with fixed prostheses (crowns, veneers, fixed partial denture, and dental implants). A further aim was to explore the level of patient's awareness and application of oral hygiene care pertaining to the fixed prosthesis. Materials and Methods: This was a cross-sectional survey. Self-reported questionnaires were administered to 320 patients wearing fixed prosthesis. The questions explored patient's subjective perception of and satisfaction with treatment outcome concerning esthetics, phonation, and masticatory function. In addition to questions related to their applied oral hygiene measures. Descriptive statistics and Spearman rank correlation coefficient tests were undertaken between the examined variables. P value was set at P < 0.05. Results: The majority (80.9%) of the patients were satisfied with their prosthesis; 78.4% were fulfilled with their chewing function; 85.3% were pleased with the esthetics; and 39.4% were satisfied by their speech. The fixed prosthesis met the expectations or partial expectations of 82.8% of the participants. Only 9.3% of the sample did not follow proper oral health care. There were moderate but significant correlation between the level of patients' expectations with and satisfaction from their prostheses (r = 0.387, P < 0.0001). Furthermore, the weak correlation between patient satisfaction and their application of oral hygiene measures was significant (r = 0.130, P = 0.020). Conclusions: Several factors (masticatory function, esthetic, and patient expectations) were correlated with the overall patients' satisfaction with their prosthesis. Dentist should continue to emphasize on the significance of maintaining good oral hygiene practice to improve patient satisfaction with their prostheses.

January-June 2018, 3(1):3-7
Background: Hyperglycemia and hyperlipidemias are common clinical problem among users of glucocorticoids (GCs). The aim of the present study was to explore the effect of oral administration of the aqueous extract of Abelmoschus esculentus peel (AEPE) on hyperglycemia and hyperlipidemia induced in rats by dexamethasone (DEXA). Methods: Twenty-four rats were randomly divided into four equal groups. Each group was treated for 10 days either with 2% carboxymethylcellulose orally (normal control); 10 mg/kg DEXA subcutaneously (hyperglycemic group); 100 mg/kg AEPE orally plus 10 mg/kg DEXA subcutaneously (treatment group 1); or 200 mg/kg AEPE orally plus 10 mg/kg DEXA subcutaneously (treatment group 2). Animals were killed after 10 days of treatments by decapitation, their blood collected for the analysis of blood sugar and lipid profile. Results: Treatment with DEXA induced a significant increase in blood glucose and all lipids and a significant reduction in body weights. After 10 days of treatment, 100 mg/kg of AEPE was able to significantly reduce the effect of DEXA on triglycerides and low-density lipoprotein (LDL) only. 200 mg/kg of AEPE was able to significantly reduce the effect of DEXA on blood glucose levels, cholesterol, triglycerides, and LDL. Both doses of AEPE were able to increase high-density lipoprotein. Conclusion: This study suggests that the AEPE could be beneficial in protecting against GC-induced hyperglycemia and hyperlipidemia.

July-December 2020, 5(2):32-36
Background: The association between maternal serum copper levels and premature rupture of membranes (PROM) is debated. Aims: This study aims to study the relationship between maternal serum copper levels and the incidence of PROM and to determine risk factors of PROM in Aleppo University Hospital of Obstetrics and Gynecology. Settings and Design: Sixty pregnant women were subjected for this study. Materials and Methods: Pregnant women were subjected for analyzing serum copper concentrations. Maternal serum copper levels were measured by atomic absorption spectroscope. Statistical Analysis: By SPSS (version 22.0). Results: A significant correlation was found between maternal serum copper levels and the incidence of PROM. The relationship presents when copper level is considered as a categorical variable, as mothers with copper deficiency were significantly more vulnerable for PROM (Odds ratios = 0.15, confidence intervals: 0.04–0.61, P = 0.002). Furthermore, the relationship presents when copper level is considered as a numerical variable, as mothers with lower serum copper levels were at significantly higher risk to develop PROM. Difference in means between the two groups was 40.87 μg/dL with CI (14.98–66.75) μg/dL (P = 0.003). Conclusion: Within its limitations, this study suggests a significant relationship between maternal serum copper levels and PROM.

Salem K Elgahmi, Nawal M Alrishei, Rabeaa H Algaraboly, Aisha A Altrablesy, Idris Mohamed El-Mahdi
January-June 2019, 4(1):33-38
Introduction: Solid dosage forms are the most commonly used dosage form for drug delivery, and tablets are more popular than capsules because of its lower production cost, minimal potential of content tampering, and the large number of designs of tablets for various applications. Aims: The aim of this work is to redesign amoxicillin hard gelatin capsules (HGCs), commonly filled into HGCs, into tablet dosage form by employing preformulation principles. Materials and Methods: Amoxicillin capsules were obtained from the local market for this purpose. Experiments included studies on flowability and effect of compression force, followed by addition of excipients, production of tablets by direct compression, and evaluation employing standard methods of friability, hardness, disintegration, dissolution, and simulation of release kinetics. Results: The flowability of powder was estimated using Carr's index, Hausner ratio, angle of repose, and bulk density. The flowability was found poor for amoxicillin alone or with starch but improved with talc. Compression force was found to be a significant factor on friability, hardness, and disintegration. The disintegration time was rapid in case of tablets containing starch compared to amoxicillin powder compressed alone. It was essential to include small amounts of disintegrant and a lubricant to optimize tablet properties. Dissolution rates for the prepared tablets were found to be acceptable, while some formulations showed a slow release profiles corresponding to their slow disintegration. Release kinetics was found to follow both the zero-order and matrix models. Conclusion: Amoxicillin capsules can be modified to a tablet dosage form with simple handling of preformulation properties.

Influence of micronization on the physical properties of salbutamol sulfate as a model drug used in dry powder inhalation
Antesar M Boshhiha, Nora Anne Urbanetz
January-June 2018, 3(1):8-15
Purpose: Investigation of the crystallinity of salbutamol sulfate a model drug used in the dry powder inhalation formulation. Materials and Methods: Salbutamol sulfate was supplied kindly by Lindopharm (Hilden, Germany). Salbutamol sulfate was milled using an air jet milling process, the particle size and morphology were determined using laser diffraction and the scanning electron microscopy. The drug was subjected to conditioning through storage at 52.8% and 75% relative humidity for 24 h, 1 week, and 2 weeks, respectively. The drug crystallinity was investigated using differential scanning calorimetry (DSC), X-ray diffraction, and water vapor sorption techniques. Results and Discussion: Conditioning of salbutamol sulfate after micronization lowers the glass transition (Tg) temperature of the amorphous parts present at particle surface, which enhances particle mobility for more rearrangement associated with water expelling. This transformation may result in deviation from the original particle size obtained after milling out of respirable range. DSC and X-ray diffraction show no detectable amorphous drug since no detectable Tg observed. Alternatively, water vapor sorption shows a small amount of amorphous salbutamol sulfate at the particle surface, which recrystallizes at 52.8% relative humidity after approximately 2 weeks of conditioning. Conclusion: The amorphous regions can be generated in crystalline materials during processing. The level of amorphous materials can affect every step of pharmaceutical formulation, storage, and stability. However, quantification of low levels of amorphous content still poses considerable challenge. This study confirms that, the water vapor sorption technique is useful in the quantification of a small amount of drug amorphous content.

January-June 2019, 4(1):18-25
Background and Objectives: Tuberculosis (TB) is an important cause of childhood morbidity and mortality. Understanding the barriers to successful childhood TB treatment is vital to curbing the scourge of childhood TB. This study examined the outcomes and factors that influence the outcomes of childhood TB treatment in a South-East Nigerian tertiary hospital. Methods: A 10-year review of the medical records of under-15 year olds, who received anti-TB treatment at Nnamdi Azikiwe University Teaching Hospital, Nnewi, was carried out. Data were analyzed using SPSS version 20. Results: Majority of the 501 childhood TB cases were new (89.6%) and pulmonary (73.3%) TB cases. TB-HIV coinfection occurred in 42.5% of cases. The rate of successful treatment was 62.9%. About 57.5% completed treatment, 5.4% were cured, 7.0% were transferred out, 21.4% were lost to follow-up, 0.4% had treatment failure while 8.4% died. Majority (61.6%) of deaths or loss to follow-up occurred during the first 2 months of treatment. Factors significantly associated with treatment outcomes were ascertainment of HIV status (P = 0.049), disease site (P = 0.013), nutritional status (P = 0.039), Mantoux test result (P = 0.002), and period of treatment (P = 0.005). Conclusion: Findings indicate high rate of unsuccessful childhood TB treatment outcomes. Efforts should be intensified to ensure improved outcomes through proactive search for childhood TB cases, early diagnosis and treatment, as well as adherence to and completion of treatment. Special attention should be given to high-risk groups including those with unknown HIV status, extrapulmonary TB, and severe malnutrition. It is imperative to determine the HIV status of all childhood TB cases.

Impact of chronic stress on cardiovascular system: Libyan conflict health perspective. Part one: Types of chronic stresses
Abdalla Salem Elhwuegi, Lamis Ali Teebar
July-December 2018, 3(2):31-35
Recent studies have provided clear and convincing evidence that chronic stress contributes significantly to the pathogenesis and expression of cardiovascular diseases (CVDs). This bibliography is a systematic review on the impact of chronic stress on the cardiovascular system with a special reflection on the Libyan conflict. It is divided into two parts, Part 1 deals with types of chronic stresses, while Part 2 deals with mechanisms involved in chronic stress and their treatments. Medline/PubMed, Google Scholar, and Scopus databases were used to search for peer-reviewed papers dealing with the review theme. Stress can be classified into acute stress and chronic stress. Chronic stress can stem from underlying factors such as economic stress, social isolation stress, posttraumatic stress, and job strain stress. Economic stress is emerging as an important determinant of perceived health where different studies have found an inverse trend between risk factor burden and cardiovascular disease prevalence in urban and rural communities in high-, middle-, and low-income regions. Social stress is another factor that has been reported to be associated with a 2–3 fold increase in the incidence of CVD. Moreover, multiple studies have shown that patients suffering from posttraumatic stress disorder have increased resting heart rate, increased startle reaction, and increased blood pressure as responses to traumatic events. CVD is one of the health outcomes whose links with work stress have been well established based on numerous prospective studies.

Hawa Juma El-Shareif
January-June 2018, 3(1):20-25
Background: The metabolic syndrome (MS) is defined as a cluster of cardiovascular risk factors, including central obesity, dysglycemia, hypertension (HPN), elevated triglycerides (TGs), and reduced high-density lipoprotein cholesterol (HDL-C). MS increases the risk of cardiovascular disease and all-cause mortality. Objective: This study aims to estimate the prevalence of MS and its components among nondiabetic Libyan females using the definition proposed by National Cholesterol Education Program (NCEP) Adult Treatment Panel III (ATP III). Methods: A total of 122 randomly selected nondiabetic Libyan females were included in the study. Detailed medical history was obtained from all participants. Blood pressure, weight, height, waist and hip circumference were measured. Body mass index and waist–hip ratio were calculated. Fasting blood glucose (FBG) and lipid profile were collected. Standard oral glucose tolerance test with 75 GM glucose was performed. The MS was defined by ATP III and International Diabetes Federation criteria. Results: According to NCEP definition, the prevalence of the MS in the study group was 42.6%. The most common component was abdominal obesity (67.2%). FBG was ≥ 100 mg/dl in 47.5%. The prevalence of both HPN and low HDL-C was 45.9%. About 26.2% of the participants have their TG ≥ 150 mg/dl; all were MS patients. Conclusions: The prevalence of MS and cardiovascular risk factors were high among Libyan females. Public health authorities and health-care providers should implement strategies for prevention, screening, and management of cardiovascular risk factors to reduce the burden of its potential complications.

Negia Abdullah Emtawel Mohamed, Ezeddin Salem Gassar, Sara A Abdulla, Mustafa Mohamed Elfakhri, Ayyub Patel, Syed Saleem Haider
July-December 2020, 5(2):37-47
Background: Exposure to vanadium exhibits deleterious neurotoxicity. Doxycycline is a potential antioxidant that prevents the progression of disease through inhibition of lipid peroxidation. Objectives: This research investigates the neuroprotective effects of doxycycline, in different rat brain areas in an animal model intoxicated with vanadium. Materials and Methods: Male Sprague-Dawley rats were equally divided into the following four groups: control group, doxycycline-treated group, vanadium-treated group, and concomitant doses of doxycycline plus vanadium-treated group, all given orally for 10 consecutive days. The animals were watched daily for any signs of neurological defects. They were sacrificed by decapitation 24 h after the last dose. Brain was removed rapidly and dissected into cerebral cortex, cerebellum, and brain stem. Biochemical studies including the concentrations of phospholipids, cholesterol, cerebrosides, glutathione (GSH), acetylcholinesterase (AChE) activity, gangliosides, ascorbic acid, calcium, and lipid peroxidation levels were determined. Results: The results revealed that vanadium produced significant reduction in body and absolute brain weight, with neurological function deficits. Vanadium significantly decreased the concentrations of phospholipids, cholesterol, cerebrosides, and GSH and inhibited AChE activity together with significant increase in gangliosides, ascorbic acid, calcium, and lipid peroxidation levels compared to saline controls. Animals which were given the combined treatment of vanadium and doxycycline regained weight and became normal. Moreover, doxycycline reversed the effect of vanadium on the metabolic variables and inhibited lipid peroxidation nearing to normal levels to that of saline controls. Conclusion: These findings demonstrated the antioxidant or chelating action of doxycycline against vanadium neurotoxicity and its therapeutic potential to avert neurodegenerative changes in different rat brain areas.

Aim: The aim of this study was to evaluate the efficacy and outcome of sutureless and glue-free conjunctival autograft for the management of primary pterygium in terms of complications such as loss of graft, graft dehiscence, and recurrence rate. Materials and Methods: A case series study was carried out in March 2015 at Nastaein private sanatorium, Zlitin, Libya. Twenty-seven eyes of 23 patients with primary pterygium were included in this study. Pterygium excision with conjunctival autografting without using sutures or glue was done to all patients. The patients were followed up postoperatively after 1 h, 1st day postoperatively, and then 1 week, 4 weeks, 3 months, 6 months, and 12 months. Results: The mean age of the patients was 55.9 ± 8.55 years (range: 43–71 years); 65% were male. Mean follow-up time was 10.2 ± 2 months. Changes of visual acuity were not noticed in any of these patients. Only one patient (3.7%) developed edge recession of the graft on the 1st postoperative day due to a wrong measurement of the size of the graft, and no other complications were noted. Cosmesis was excellent in all cases and no recurrence was noted. Conclusions: Sutureless and glue-free conjunctival autograft for primary pterygium surgery is a safe and effective way for the management of primary pterygium.

LJ Abdulmalek
July-December 2017, 2(2):101-111
BACKGROUND: This study intended to assess knowledge, attitudes, and practices regarding standard precautions concerning health care-associated infections (HAIs) among hemodialysis nurses in hemodialysis centers in Benghazi. METHODS: the study was a cross sectional study carried out during the period from 1-3-2014 till 30-9-2014. The data was gathered from hemodialysis nurses in hemodialysis centers in Benghazi by using a questionnaire and by direct interview. RESULTS: There were a total of 59 hemodialysis nurses in hemodialysis centers in Benghazi. All agreed to participate in the study. Although 92% of the nurses knew that their hands could be a source of health care-associated infections, but only 52% of nurses washed their hands before contacting another patient. Gloves were actually used by 98% of the nurses. 46% of the nurses were usually wearing masks when contacting a patient. Books and journals were the main source of information about (HAI) among 52% of the nurses. CONCLUSION: The nurses' knowledge of health care-associated infections did not modify their adherence to hand hygiene practices. This study recommend training programs for hemodialysis nurses about promoting higher hand hygiene standards and potential use of personal protective measures during their shifts in hemodialyais centers.

July-December 2018, 3(2):59-64
Background: Chronic liver disease (CLD) is a disease with significant morbidity and mortality in Nigeria. This study assessed the sexual functions of women with chronic hepatitis B infection (CHB), liver cirrhosis (LC), and hepatocellular carcinoma (HCC) designated as cases and normal women as controls. Methods: A prospective, comparative, case–control study of CHB, LC, HCC, and controls. Consenting cases and controls completed a self-administered Female Sexual Function Questionnaire (FSFI). Bio-data was obtained for all participants and cases were graded using the Child–Turcotte–Pugh scores (CTP). Data obtained were entered into SPSS version 20 and analyzed using descriptive and inferential statistics. Results: A total of 176 women completed the study, comprising 88 cases and 88 controls. Mean age (standard deviation) was 39.5 + 8.5 years and 40.5 + 8.2 years for cases and controls, respectively. Cases comprised CHB – 46, LC – 25, and HCC – 17, and their CTP classes were CTP A, 54; CTP B, 22; and CTP C, 12. The FSFI scores for CHB compared with controls were not statistically significant in all domains of the FSFI. The FSFI scores for LC and HCC in all domains were statistically significant compared with controls. Total mean FSFI scores for cases in CTP Class C showed sexual dysfunction, where 13.6% of CLD and 6.8% of all participants had sexual dysfunction and none among the controls. Conclusions: Females with advanced CLD had sexual dysfunction. Sexual concerns of females with CLD should be inquired for and treated.

Recent studies have provided clear and convincing evidence that chronic stress contributes significantly to the pathogenesis and expression of cardiovascular diseases (CVDs). This bibliography is a systematic review on the impact of chronic stress on the cardiovascular system with a special reflection on the Libyan conflict. It is divided into two parts, Part 1 deals with types of chronic stresses, while Part 2 deals with mechanisms involved in chronic stress and their treatments. Medline/PubMed, Google Scholar, and Scopus databases were used to search for peer-reviewed papers dealing with the review theme. Mechanisms responsible for the development of chronic stress are either behavioral or biological. Behavioral factors include lifestyles (e.g., smoking, alcohol, and physical inactivity). Biological mechanisms include sympathetic overdrive, hypothalamic–pituitary–adrenal axis overactivity, and low activity of central gamma-aminobutyric acid. Chronic stress managements and treatment strategies include psychological treatment like cognitive behavioral interventions, breathing techniques like Yoga and/or pharmacological treatments like selective serotonin reuptake inhibitors, and drugs that inhibit sympathetic hyperactivity.

July-December 2018, 3(2):49-53
Objective: The present prospective study was carried out in Surgical Department of Tripoli Central Hospital with the aim to evaluate the effect of preoperative single dose of 150 mg pregabalin in reducing postoperative pain and analgesic consumption after laparoscopic cholecystectomy. Patients and Methods: Sixty patients of both sexes in the age of 18–60 years undergoing laparoscopic cholecystectomy were randomly allocated into two equal groups of 30 patients each. The pregabalin group received 150 mg oral pregabalin 1 h before induction of anesthesia and a placebo group received a matching placebo orally. Variables measured included age, sex, body mass index (BMI), duration of surgery, time to first dose and total dose of meperidine after recovery, and the visual analog scale (VAS – static and dynamic). The occurrence of nausea and vomiting during the first 24 h postoperative was also recorded. Results: No significant difference was found between the meperidine and the placebo groups regarding age, sex, BMI, or duration of surgery. The time of first meperidine dose required to alleviate pain after surgery was significantly four times longer in the pregabalin group as compared to the placebo group. The total dose of meperidine required for pregabalin group was significantly lower than that required for placebo group. Moreover, VAS was significantly decreased in the pregabalin group compared to placebo group both at static and dynamic states only 1 h after recovery. Conclusion: This study validates the preoperative use of a single dose of pregabalin in attenuating pain intensity postoperatively and reducing total analgesic consumption.

July-December 2018, 3(2):65-68
Aims: Deafness is a pathology that interferes in several aspects of the emotional, psychological, social, and intellectual life. Cochlear implants are electronic devices that allow hearing rehabilitation. This study is carried out to show our experience in cochlear implantation at Benghazi Medical Center, Libya. Patients and Methods: A retrospective descriptive study was performed over 110 patients at the Otorhinolaryngology Department, Benghazi Medical Center, between August 2012 and April 2016. The patients were analyzed according to the age, sex, type of implant inserted, approach, and intraoperative and postoperative complications. Two types of implant devices were used: cochlear and MED-EL. Surgery was done by the same surgical team. Results: Seventy of all patients operated for cochlear implantation were male (63.6%), while forty were female (36.4%). One hundred and four (94.5%) were children and 6 (5.55%) were adults. One hundred (91%) cases were prelingually deaf and 10 (9%) were postlingual deafness. Telemetry showed satisfactory neural response in 107 (97.35) cases. Failure to insert the electrode in 1 (0.9%) case as the cochlea was ossified bilaterally. Extrusion of the receiver took place in 1 (0.9%) case. One (0.9%) patient had extrusion after 2 years; another 1 (0.9%) had wound dehiscence. Despite our few years of experience in cochlear implantation, we have achieved the requirement of our patients. The need for structured services and trained professionals in this type of procedure is clear.

Sulforaphane in experimental hypertension
Ali Banigesh, Vijitha Senanayake, Salma Bukhatwa, Bernhard Juurlink
July-December 2020, 5(2):27-31
Background: Hypertension is defined as a failure to achieve a blood pressure (BP) target – smaller than 140/90 mmHg. The worldwide burden of hypertension has been associated with globally increased rates of death and disability. There is increasing evidence of strong relation between hypertension and oxidative stress, where either increased oxidative stress or depressed antioxidant level may lead to hypertension. Using stroke-prone spontaneously hypertensive rats (SHRSP) rats, previous studies in our laboratory have shown that broccoli sprouts (high in sulforaphane, a phase-2 protein inducer) attenuate BP and inflammation. Objectives: The question this study addressed was whether sulforaphane (a potent phase-2 protein inducer) can attenuate hypertension in the experimental model using the stroke-prone spontaneously hypertensive rats (SHRsp). Materials and Methods: Sulforaphane (LKT Laboratories) or vehicle was orally gavaged to SHRsp or Sprague–Dawley rats (SD) daily for 15 weeks. The body weight and BP were determined weekly, using a standard tail-cuff BP measurement. Tissues such as hearts and kidneys were collected, weighed, and stored under −80°C for further analysis. Results: When compared to BP in SHRsp control rats (179.9 ± 4.32), sulforaphane significantly reduced BP to 157 ± 5.21 (10 μmol/kg body weight), 136.57 ± 1.96 (20 μmol/kg body weight), and 129.33 ± 6.10 (5 μmol/kg body weight), respectively, in SHRsp rats. Conclusion: Administration of sulforaphane, a potent phase-2 enzyme inducer, daily for more than 3 months, significantly improves BP in SHRsp rats, but it did not have any effects on normotensive rats – SD.
