Objectives: The study was done to determine the physicians′ perception about electronic medical record system (EMRS) in the context of its productivity in order to improve its functionality and advantages. Materials and Methods: This cross-sectional survey was performed from July to August 2009 with structured questionnaire of 15 closed-ended questions with five points Likert scaling starting from strongly disagree to strongly agree as 1-5, reflecting the perception of physicians about EMRS. The physicians of the Makkah region working in six different hospitals were selected. "Positive" response means if percent of responses were rated 4 or 5 (agree/strongly agree), "neutral" if rated 3, and negative if rated 1 or 2 (strongly disagree/disagree). Descriptive data analysis techniques were used. Results: We selected 317 completed questionnaires. Majority of subjects were from King Fahd Hospital, Jeddah (83, 26.3%), residents (147, 46.4%), male (200,63.1%), expatriates (207, 65%), and age group 36-45 years (133, 42%) were dominant. The stem regarding importance of computers for practicing medicine and EMRS to improve quality of practice was appreciated by majority, that is, 77.7 and 71.2%, respectively. However, "It does not disrupt the workflow" (35.1%) and "EMRS is comfortable while entering the data instead of writing" (34.8%) were appreciated negatively. Consultants (53.9%), male (53.4%), expatriates (56.7%), physicians of King Abdul Aziz Hospital, Ta′if (56.9%), and age group of 46-55 years (53.8%) appreciated EMRS positively. Overall perception of EMRS was found positive by 52.8%. Conclusion: Majority appreciated the EMRS, but specific concerns about its usage easiness and workflow disturbance were opposed by them also.

A 75-year-old male patient presented to the Speech and Language Disorder Outpatient Clinic of King Abdullah Medical City, Makkah, Saudi Arabia, on February, 2010, with a complaint of gradual onset and progressive course of dysphonia for 2 years. Nasofibrolaryngoscopic examination indicated a polipoidal mass of about 1.5 × 1 cm masking the entire glottic inlet. The mass was removed by direct laryngoscopy and diagnosed as a malignant fibrous histiocytoma. The patient developed recurrence of the tumor on the same site postoperatively and underwent the same procedure of excision, followed by a second recurrence. Direct laryngoscopic excision of the tumor was performed for a third time, but with a safety margin of 2 mm. Monthly follow-up examination indicated no postoperative recurrence till 10 months.

Objectives. Our study aimed to highlight the effectiveness of palatal lift prosthesis in patients with velopharyngeal insufficiency with previous operated cleft palate. Methods. This study was done undertaken January 2008 to December of 2009 in the Phoniatic unit of Alnoor Specialist Hospital, Makkah, Saudi Arabia. Ten patients of ≥ 8 years to ≤ 10 years of age, who had previously undergone surgery for cleft palate, with or without cleft lip, with no other systemic illness and normal intelligent quotient level, were selected and managed by palatal lift prosthesis. All the study subjects were subjected to auditory perceptual speech evaluation for assessment of the degree of hypernasality, compensatory articulator mechanisms, glottal and pharyngeal articulation, audible nasal emission, facial grimace and overall intelligibility of speech. Data were analyzed using SPSS version 16. Results. The study included 10 subjects whose mean ± standard deviation of age was (8.9±0.9). On auditory speech perceptual evaluation after prosthesis application, significant improvement was found in glottal articulation 6 (85.7%), p=0.04, facial grimace 6 (85.7%) p=0.04, hyper nasality 10 (10%) p=0.008, and speech intelligibility 9 (90%) p=0.008. Conclusion. Young patients with repaired palatal cleft have significant improvement after application of palatal lift prosthesis.

Small cell carcinoma of the ovary, hypercalcemic type (SCCOHT) is a very rare and lethal tumor, mostly affecting young women, with aggressive clinical course. It has a worse prognosis in younger women and most of them died within two years of diagnosis. We are reporting a unique case of SCCOHT in a 35 years old, nulliparous lady with primary infertility in which symptomatic hypercalcemia was a presenting feature of her cancer. She was completely healthy before third cycle of IVF. Within two months of her third IVF cycle, she developed SCCOHT with a very rapid and aggressive course of disease and fatal outcome. Patient died within one month of her first symptom presentation (3 months after IVF cycle).

Objective To evaluate the validity of Crypto-Giardia antigen rapid test (CA-RT) in comparison with the conventional modified Ziehl-Neelsen acid fast (MZN-AF) staining method for the diagnosis of cryptosporidiosis. Methods Fifteen preserved stool samples from previously confirmed infections were used as positive controls and 40 stool samples from healthy people were used as negative control. A total of 85 stool samples were collected from suspected patients with cryptosporidiosis over 6 months during the period from January till June, 2011. The study was conducted in the department of parasitology, central laboratory, Alnoor Specialist Hospital, Makkah, Saudi Arabia. All samples were subjected to CA-RT and conventional MZN-AF staining method. Validation parameters including sensitivity (SN), specificity (SP), accuracy index (AI), positive predictive value (PPV), and negative predictive value (NPV) were evaluated for both tests. Results Out of 15 positive controls, CA-RT detected 13 (86.7%) while MZN-AF detected 11(73.3%) positive cases. However, CA-RT detected no positive case in 40 normal controls but MZN-AF detected 2(5%) as positive cases. Based on the results, the SN, SP, AI, PPV and NPV were high in CA-RT than MZN-AF staining method, ie., 86.7% vs. 73.3%, 100% vs. 95%, 96.4% vs. 89.1%, 100% vs. 84.6% and 95.2% vs. 90.5%, respectively. Out of a total of 85 suspected specimens, CA-RT detected 7(8.2%) but MZN-AF detected 6(7.1%) cases as positive. Conclusions CA-RT immunoassay is more valid and reliable than MZN-AF staining method.

Background and Objectives: A confidential inquiry by the Directorate General of Health Affairs, Makkah region, Saudi Arabia, found physicians in different hospitals were reluctant to enter patients' related information in electronic medical record systems. One of the major issues raised was that they didn't have the required computer literacy. Our aim, therefore, was to conduct a survey to highlight the computer literacy among the physicians of Makkah region. Materials and Methods: This cross-sectional survey was performed from May to July 2009. A structured questionnaire of four A4 size paper was distributed among the physicians of the Makkah region working in seven different hospitals. The questionnaire contained questions on background knowledge of computers, i.e., (a) basic computer vocabulary knowledge (BCVK) (10 questions), (b) basic computer skills (BCS) (22 questions), (c) basic communication and internet skills (BCIS) (12 questions). Results: Response rate of 368, i.e., 81.6% of sample size ( n = 451) was attained. The maximum response came from King Abdul Aziz Hospital (Taif), i.e., 79%. Overall BCVK, BCS and BCIS were the highest among the physicians of Alnoor Specialist Hospital, i.e., 71.3%, 91.4%, 87.7%, respectively. All the hospitals had a satisfactory level of BCVK, but levels of BCS and BCIS were above satisfactory except King Abdul Aziz Hospital (Jeddah) that showed a satisfactory level in BCIS. Conclusion: Majority of the physicians had a good or an excellent level of computer background knowledge that gave a prediction toward the issues of their non-promising attitude and beliefs about electronic data entry.

Objectives: The objective was to highlight the frequency, clinical profile, and predisposing factors of ectopic pregnancy (EP) in a general hospital. Materials and Methods: This descriptive study was conducted at the Obstetrics and Gynaecology department of Hera General hospital, Makkah, Saudi Arabia, from July 1, 2009 to December 29, 2010. Data were collected on chief medical complaints, sociodemographic characteristics, past obstetrics and gynecological history, management done, and outcome of management. Data were analyzed using Microsoft Office Excel (version 2007). Results: Out of total 7564 pregnancies, 44 (0.58%) patients were diagnosed as EP. Out of 44, 22 (50%) patients presented within 24 h of onset of symptoms. Mean age was 28 ± 7 years. Multigravida were predominant in 25 (57%), and 21 (48%) had gestational age of 6-8 weeks at the time of presentation; the common presenting features were amenorrhea (41, 93.2%), abdominal pain (39, 88.6%), and tenderness (38, 86%). Previous pelvic surgery (13, 29.5%), infertility treatment (11, 25%), and pelvic inflammatory disease (10, 22.7%) were the common predisposing factors. Twenty-five (57%) presented with ruptured EP and were operated within 24 h, and the remaining were kept under observation till further diagnosis. After confirming the diagnosis, 12/19 underwent laparoscopy, whereas 7/19 received medical treatment. Surgery confirmed fallopian tube pregnancies in 35 (94.5%). No mortality was observed. Conclusion: Previous pelvic surgeries were the major etiological factor for EP. Other factors were infertility treatment and pelvic inflammatory disease. The most common site of EP was fallopian tubes.

In this study, Al/Cu2O–PEPC/Al pressure transducer was designed and fabricated by drop-casting the blend of Cu2O–PEPC microcomposite thin films of copper oxide (Cu2O) micropowder, (3 wt.%) and poly-N-epoxypropylcarbazole, PEPC, (2 wt.%) in benzol on Al substrates. The thicknesses of the Cu2O–PEPC films were in the range of 30–100 μm. The AC resistance and capacitance at 120 Hz of the transducer was decreased by 1.1–1.4 and increased by 1.2–1.8 times, respectively, as the pressure was increased up to 100 kPa. The resistance-pressure and capacitance-pressure relationships were simulated.

Objectives: This study aimed to highlight the association of HbA1c with diabetic related complications. Material and Methods: This retrospective study has been conducted in endocrinology department of Alnoor Specialist Hospital, Makkah, Saudi Arabia, from January 2007 to December 2009. Data has been collected from diabetic patients’ files that were referred to the diabetes outpatient department either because of consultation from other health care centers or from other departments of the same hospital due to diabetes related complications. Patients’ files were reviewed for levels of HbA1c and diabetes related complications. The values of HbA1c were considered at the time of diagnosis of complications. Results: The total study subjects were 110 with mean HbA1C was 7.3 with range (5.9-11.3). Only significant association between the HbA1c and diabetic septic foot was seen (p value=0.037) while values of regression showed that HbA1c is best correlated with cardiovascular disease (R=0.39, Beta =0.004 and pvalue = 0.104). Conclusion: Our study results showed insignificant association between the HbA1c and diabetic complications except that of with diabetic septic foot.

Introduction The annual pilgrimage to Mecca (Hajj) is one of the largest gatherings in the world and thus its participants are exposed to various communicable and noncommunicable diseases. This provides an opportunity to study travel epidemiology. Objectives The aim of the study was to estimate the predictors of asthma severity during the Hajj. Patients and methods The study cohort was recruited from patients who presented to the emergency department (ED) of the King Abdul Aziz Hospital, Mecca, Saudi Arabia, between December 3 and 18, 2008 (5-20 Dhul-Hijjah 1429 H). We included newly diagnosed and previously documented cases presenting with asthma symptoms. Sociodemographic and clinical data were collected and the risk factors were assessed. The severity of asthma exacerbation was measured according to the National Heart, Lung, and Blood Institute guidelines. Data were analyzed using the SPSS software. Results The study involved 58 subjects, including 38 women (65.5%). There were 27 subjects (46.6%) with mild asthma attack, 18 (31%) with moderate asthma attack, and no cases with life-threatening asthma. Insignificantly increased risk of severe asthma attack was observed in the following groups: women, people aged 46-60 years, pilgrims (hajis) who did not belong to a hajj group, non-hajis, illiterates, and nonsmokers - the odds ratio (OR) (95% confidence interval [CI]) was 3.7 (0.7-18.5), 1.7 (0.5-6.3), 2.4 (0.7-8.5), 5.1 (0.6-44.1), 2.3 (0.7-9.1), and 2.0 (0.4-10.4), respectively. Forty-six subjects (79.3%) had a history of allergy to components of smoke, detergents, dust, animal dander, and perfumes, while only 5 patients (8.6%) had drug allergy. High risk of severe asthma was observed in subjects with a history of drug allergy, as well as in obese subjects and those who often presented to the ED - OR (95% CI) was 6.5 (0.9-43.9), 18.0 (4.0-80.7), and 3.1 (0.8-11.5), respectively. Conclusions Higher risk of severe asthma attack was observed in women, people aged 46-60 years, hajis who did not belong to a hajj group, non-hajis, illiterates, nonsmokers, obese patients, and those who often presented to the ED within the previous 12 months due to asthma exacerbation.

Background: Polycystic ovary syndrome (PCOS) is the commonest endocrinopathy in women that is associated with reproductive and metabolic disorders. Objectives: We compared the ovulation and conception rates after the treatment with clomiphene citrate (CC) alone and in combination with metformin in infertile patients presented with polycystic ovarian syndrome (PCOS). Materials and Methods: This randomized controlled trial of independent cases and controls was conducted at the Department of Obstetrics and Gynecology, Hera General Hospital, Makkah, Saudi Arabia from February 01 to December 31, 2008. The 42 subjects diagnosed as PCOS were divided into group A and B (21 subjects in each) for management with CC + metformin and CC alone, respectively. Group A received 500 mg three times a day of metformin continuously from the first cycle for 6 months or till pregnancy was confirmed. In both groups CC was started at a dose of 50 mg from day-2 till day-6 of the menstrual cycle. The dose of CC was increased to 100 mg in second and 150 mg in third cycle, and then remained 150 mg for the remaining three cycles. With ovulation the dose of CC was unaltered in both groups. Data were analyzed using Statistical Package for the Social Sciences (SPSS) version 16. Results: More than 50% females in both groups were had body mass index > 25. Group A achieved high rate of regular cycles, ovulation success, and conception than group B (71.4% vs. 38.1%; P = 0.03), (76.2% vs. 38.1%; P = 0.021), and (66.6% vs. 28.6%; P = 0.01), respectively. Conclusion: Management with metformin + CC increased the ovulation and conception rates.

In this study V 2 O 4 -PEPC composite based temperature sensors were designed and fabricated by drop-casting the blend of V 2 O 4 -PEPC microcomposite into thin films between the gap of preliminary deposited electrodes on a glass substrates. The blend was prepared by mixing 10 wt.% vanadium oxide (V 2 O 4 ) micro-powder and 2 wt.% poly-N-epoxypropylcarbazole (PEPC) in 1 ml of benzol. The thickness of the V 2 O 4 -PEPC films was in the range of 20–40 μm. The gap between silver electrodes was in the range 30–40 μm. The length of silver electrodes was equal to 15 mm. It was found that with increase in temperature from 33 °C to 90 °C the AC resistance of the samples decreases by 10–12 times. The resistance-temperature relationships were simulated.

Stool examinations were performed by direct method and concentrated Techniques for all patients. RESULTS Overall, the prevalence of intestinal parasites was 6.2% (740 cases). Majority of patients were infected by Entamoeba histolytica (4.7%) followed by Giardia lamblia (1.3%), while Ankylostoma duodenal (0.02%) exhibited the minimum prevalence. Parasitic infections were more frequent in non-Saudis than Saudis patients (7.1% vs. 5.8%; p

The incidence of patients with end-stage renal failure and type 2 diabetes mellitus as a comorbid condition has increased progressively in the past decades. Causes of renal disease might vary from one population to another. The aim of this study was to know the characteristics of the diabetic patients on regular dialysis at Al-noor Specialist Hospital, Makkah, SaudiArabia. The data had been collected retrospectively in the month of Shawal 1425 corresponding to 13-11-2004----12-12-2004 from the diabetic patients directly that were on dialysis due to end stage renal disease (ESRD) and from their files. The mean age of Diabetics was (55.2years) showing male predominance 31(60.8%). All were Saudies. The mean duration of Diabetes mellitus & dialysis were (16.8years) and (22months), respectively. The mean age of start of Diabetes mellitus & dialysis was (37.4 years) & (53.5 years). The mean duration of onset of diabetes to dialysis was (16.1 years). Out of the total, 29(56.9%) were non-smoker. Patients with family H/O diabetes with other associated illnesses were 23(45%) followed by 15(29.4%) had family H/O only diabetes. Type II diabetics were 40(78.4%). Regarding metabolic profile, patients with high blood glucose level were 10(19.6%) while 3(5.9%), 50(98%) & 18(35.3%) patients had high cholesterol, low density lipoprotein & triglyceride levels, respectively. Maximum patients were in sixth decade of life. Up to three fourth patients had family H/O diabetes. Most of the subjects had only diabetic nephropathy.

This study highlighted the reasons which contributed to longer stay of patients in Emergency Department (ED) who were advised admission.This study was conducted from August 4 to 11, 2004G as a retrospective review of the ED cards of patients admitted to inpatients wards of Al-Noor Specialist Hospital, Makkah, Saudi Arabia. The demographic data, doctorsnurses notes with their timings were reviewed. The maximum consumed time by a reason was considered as the main reason of delay for that subject. The delayed patients were divided into Group A and B, delayed before and after admission was advised, respectively. Prolonged length of stay (Delay) in ED was defined as stay longer than 2 hours after patient's arrival in ED until they were received to wards.Out of total 4876 visits during study period, 355 (7.3%) patients were admitted, and 238 (67%) were delayed. Age group 13-30 years was common in delayed 78 (32.8%) and not delayed 56 (47.9%) subjects. The mean length of stay of delayed subjects was 256 minutes. Group A 146 (61.4%) had more subjects than group B 92 (38.6%) (p0.001). Fifty eight (39.7%) patients stayed between 2-3hours in Group A vs. B 23 (25%) (OR 2, 95% CI 1.1-3.5). Common reason of delay in Group A was multiple consultations with further investigations 70 (48%) (p0.001) while file making process was common 40 (43.5%) in group B (p0.001).Out of admitted patients 67% were delayed mainly due to late advised admission with major reason of delay were multiple consultations.

We have reported a case of a 40-year-old male diabetic patient, resident of a rural area, who visited the outpatient clinic of the diabetic center in Alnoor Specialist Hospital, Makkah, Saudi Arabia. He came to seek medical advice for a single wound in the back of the shoulder since 1 month. After examination, a larva was eliminated and sent to laboratory for confirmation. It was confirmed as the third-stage larva of Sarcophaga species after macroscopic and microscopic examination. This is the first case of a patient having diabetic wound myiasis with the larva of Sarcophaga species reported in the Makkah region of Saudi Arabia.

Background: The objective was to determine the effectiveness of Doppler velocimetry results in the management of high‑risk pregnancy. Materials and Methods: This cohort study was conducted from January 2005 to December 2006 in Obstetrics and Gynecology Department of Alnoor Specialist Hospital, Makkah, Saudi Arabia. A total of 200 high‑risk pregnant women with gestational age >28 weeks were selected for the study and divided into group A (100) subjected to Doppler velocimetry and group B (100) without Doppler velocimetry. Standard management protocols were followed in all cases. The primary outcome measures were mode of delivery and gestational age at the time of delivery. The secondary outcome measures were prenatal and neonatal complications. Data were analyzed using SPSS version 16 (SPSS Inc., Chicago, IL, USA). Results: Preterm deliveries, preterm as well as full‑term neonatal admissions were more frequent in group A than those in group B, i.e., (39% vs. 26%), (56% vs. 88%) (OR 0.2, 95% CI 0.04‑0.7), and (30% vs. 57%) (OR 0.3, 95% CI 0.2‑0.7), respectively. Similarly preterm and full‑term neonatal deaths were rare in group A than those in group B, i.e., (9% vs. 78%) (OR 0.1, 95% CI 0.02‑0.7), and (6% vs. 29%) (OR 0.2, 95% CI 0.03‑1.8), respectively. Emergency caesarean section rate was rare in the subjects with normal Doppler than those with abnormal Doppler (48% vs. 100%) (OR 0.1, 95% CI 0.03‑0.4) as well as in group B (48% vs. 82%) (OR 0.2, 95% CI 0.1‑0.4). Conclusion: Doppler studies in high‑risk pregnancies are more beneficial in the management of perinatal as well as neonatal management.Keywords: Caesarean section, color Doppler ultrasonography, pregnancy outcome, prematurityNigerian Medical Journal | Vol. 53 | Issue 3 | July-September | 2012

A thin film of blended poly-N-epoxypropylcarbazole (PEPC) (25 wt.%), nickel phthalocyanine (NiPc) (50 wt.%) and ZnO nano-powder (25 wt.%) in benzene (5 wt.%) was spin-coated on a glass substrate with silver electrodes to produce a surface-type Ag/PEPC/NiPc/ZnO/Ag capacitive and resistive sensor. Sensors with two different PEPC/NiPc/ZnO film thicknesses (330 and 400 nm) were fabricated and compared. The effects of humidity on capacitance and resistance of the Ag/PEPC/NiPc/ZnO/Ag sensors were investigated at two frequencies of the applied voltage: 120 Hz and 1 kHz. It was observed that at 120 Hz under humidity of up to 95% RH the capacitance of the sensors increased by 540 times and resistance decreased by 450 times with respect to humidity conditions of 50% RH. It was found that the sensor with a thinner semiconducting film (330 nm) was more sensitive than the sensor with a thicker film (400 nm). The sensitivity was improved when the sensor was used at a lower frequency as compared with a high frequency. It is assumed that the humidity response of the sensors is associated with absorption of water vapors and doping of water molecules in the semiconductor blend layer. This had been proven by simulation of the capacitance–humidity relationship.
