Abstract
This intervention study was conducted to determine the efficacy of Levofloxacin in the treatment of uncomplicated enteric fever. Among 100 patients, who were purposively selected for the study had presented sign and symptoms of enteric fever with blood culture positive salmonella in laboratory findings during the admission in the department of Medicine, Uttara Adhunik Medical College & Hospital, Dhaka. Patients who fulfilled the diagnostic criteria were enrolled in the study and divided into two groups. One group was treated with oral levofloxacin 750mg once daily (OD) and another was injected with Levofloxacin 500mg once daily for 7 days. All the patients were examined twice daily to observe the clinical cure or failure of levofloxacin. Study was conducted from January 2008 to December 2008. Statistical analysis was performed by using statistical software SPSS version 12. Among the 100 patients in the study, majority of them 46(92%) were aged between 15 to 25 years, the next group was between 25 to 35 years 26(52%) and only three patients were aged above 65 years. Significant number of the patients were male (67), and the rest of them were female. The patients were clinically examined specially for anaemia, jaundice, caecal gurgling, hepatosplenomegaly in both the groups and the relevant investigations were performed. It was found that 46 patients in group A, who took oral levofloxacin, were cured after seven days, whereas 48 patients in group B were fully cured by taking injectable levofloxacin by seven days. In this study, levofloxacin was found to be the most effective drug in both oral and injectable form in one-week treatment of uncomplicated typhoid.

Abstract
The structure and magnetic properties of MnFe(2)O(4) ferrites have been investigated using five different preparation methods, including the ceramic technique, flash combustion, co-precipitation, sol-gel and citrate methods. The characteristics of one sample prepared by different methods have been studied to select the better method, i.e. the one that is the simplest and does not require an elaborate instrumental set-up. The results indicated that the citrate method gives the lowest value for the lattice parameter and particle size (14.1 nm), while the highest values are obtained with the ceramic method. The smallest nanosizes were obtained in the citrate and flash methods (14.1 and 40.7 nm, respectively).

Abstract
UNLABELLED We compared the effect of different frequencies of repetitive transcranial magnetic stimulation (rTMS) (1 Hz, 10 Hz, 25 Hz and sham (occipital, 1 Hz)), given daily over the left temporoparietal cortex for 2 weeks, on 66 patients with chronic tinnitus randomly divided into four treatment groups. Patients were assessed using the Tinnitus Handicap Inventory, self-ratings of symptoms and audiometric measures of residual inhibition before, immediately after 2 weeks' treatment and monthly thereafter for 4 consecutive months. RESULTS There were no significant differences in basal measures between the four groups of patients. A two-factor ANOVA revealed a significant "rTMS" x "time" interaction for all measures. This was because real rTMS produced greater improvement than sham. However, there was no significant difference between the responses to different frequencies of rTMS. The response to rTMS depended on the duration of tinnitus: patients who had tinnitus for the longest period of time were the least likely to respond to treatment. CONCLUSION Daily sessions of rTMS over the temporoparietal cortex may be a useful potential treatment for tinnitus.

Abstract
Obesity and its associated metabolic pathologies are the most common and detrimental diseases, affecting over 50% of the adult population. Our knowledge about the protective effects of melatonin against high-fat diet (HFD)-induced obesity is still marginal. In this investigation, we hypothesized that melatonin can minimize the metabolic pathologies and morphological changes associated with obesity in animals receiving an HFD. To examine these effects, and to test our hypothesis, an animal model formed of male Boscat white rabbits was established. The animals were divided into three groups: (i) a control group fed regular diet; (ii) an obesity group fed an HFD for 12 weeks; and (iii) a treated group fed HFD for 12 weeks and then treated with melatonin for 4 weeks. The animals were killed and their serum and tissues were evaluated for: (i) lipid profile (cholesterol, triglycerides and low-density lipoprotein) and glucose; (ii) antioxidant enzyme (serum glutathione peroxidase, GSH-PX); and (iii) fatty changes (liver, kidney and blood vessels). Compared with the control group, intake of HFD (obesity group) was associated with: (i) a statistically significant increase in blood pressure, heart rate, sympathetic nerve activity, body weight, food consumption, serum lipids, blood glucose levels and atherogenic index; (ii) decreased level of GSH-PX and high-density lipoprotein (HDL); and (iii) fatty changes in the liver and kidney as well as atheromatous changes in the blood vessels. Compared with the obesity group, intake of melatonin (treated group) was associated with: (i) a statistically significant decrease in blood pressure, heart rate, sympathetic nerve activity, body weight, food consumption, serum lipids, blood glucose levels and atherogenic index; (ii) increased level of GSH-PX and HDL; and (iii) disappearance of fatty changes in the liver and kidney as well as atheromatous changes in the blood vessels. The administration of melatonin reduced the metabolic pathologies associated with the intake of HFD, suggesting a protective role. Although the underlying mechanisms are unclear, they may include its antioxidant and receptor-mediated effects. The clinical ramifications of these effects await further investigations.

Abstract
During the period January 2002-December 2004, we assessed 30 sickle-cell anaemia patients admitted to hospital in Al Khobar with vaso-occlusive crisis for levels of antithrombin (AT) III, protein C (PC) and protein S (PS). We also did platelet aggregation studies. Steady state levels were assessed during follow-up and compared with 36 adult controls. Levels of PC, PS and AT III in the control group were significantly higher than in those in vaso-occlusive crisis and those in steady state (P < 0.001). There was a statistically significant difference between controls and patients for all platelet aggregation factors except adrenaline. There was no significant difference between the levels of PC, PS, AT III and platelet aggregation variables in patients in the steady state and in vaso-occlusive crisis.

Abstract
BACKGROUND AND OBJECTIVE A single session of repetitive transcranial magnetic stimulation (rTMS) over motor cortex had been reported to produce short term relief of some types of chronic pain. The present study investigated whether five consecutive days of rTMS would lead to longer lasting pain relief in unilateral chronic intractable neuropathic pain. PATIENTS AND METHODS Forty eight patients with therapy resistant chronic unilateral pain syndromes (24 each with trigeminal neuralgia (TGN) and post-stroke pain syndrome (PSP)) participated. Fourteen from each group received 10 minutes real rTMS over the hand area of motor cortex (20 Hz, 10x10 s trains, intensity 80% of motor threshold) every day for five consecutive days. The remaining patients received sham stimulation. Pain was assessed using a visual analogue scale (VAS) and the Leeds assessment of neuropathic symptoms and signs (LANSS) scale, before, after the first, fourth, and fifth sessions, and two weeks after the last session. RESULTS No significant differences were found in basal pain ratings between patients receiving real- and sham-rTMS. However, a two factor ANOVA revealed a significant "+/- TMS" x "time" interaction indicating that real and sham rTMS had different effects on the VAS and LANSS scales. Post hoc testing showed that in both groups of patients, real-rTMS led to a greater improvement in scales than sham-rTMS, evident even two weeks after the end of the treatment. No patient experienced adverse effects. CONCLUSION These results confirm that five daily sessions of rTMS over motor cortex can produce longlasting pain relief in patients with TGN or PSP.

Abstract
The objective of this study was to investigate various macroscopic and microscopic features of the placenta in pregnancies complicated by diabetes according to White's classification. A total of 148 placentas were studied. Sixty-five were from control patients and 83 from diabetic mothers. The diabetic mothers were further divided into three groups according to White's classification. There were 40 cases in White's group A and 36 cases in White's group B. There were 7 cases in White's groups C and D combined. Advanced maternal age and grandmultiparity were significantly higher in White A, White B and White C&D compared to the normal group. Mean weight of the mother was higher in White group A and group B compared to the control group and group C&D. The placental weight and neonatal weight were increased provided the diabetes was not complicated by vascular disease. With accompanying vascular disease the placental weight and neonatal weight were reduced compared to the controls. As a result of increased perinatal jeopardy the rate of operative delivery was higher in diabetic mothers. No major difference was observed in microscopic changes of placentas in different groups according to White's classification and the normal group.

Abstract
OBJECTIVE To document the frequency of the ABO and Rhesus blood groups in Saudi male donors, and to compare our results with the results of other studies in the Kingdom and elsewhere. METHODS This study included a total of 57396 male potential blood donors; 19496 blood donors between the years 1985-1989 (referred to as first period of study) and 37700 blood donors between the years 1995-1999 (2nd period). The blood donors were Saudis, coming to donate blood for various reasons to the Blood Bank Department of King Fahd Hospital of the University, Al-Khobar, Kingdom of Saudi Arabia. ABO and Rhesus blood groups from 200 Saudi females were also determined. The frequency of ABO blood groups and Rhesus status were calculated separately. RESULTS Our results revealed the most common blood group was O, (52%) during the first period of study and likewise the most common blood group (51%) during the 2nd period. The lowest blood group frequency was AB (4%) and (4%) during the first and 2nd period. Rhesus positive blood donors comprised 93% and Rhesus-negative donors were 7% during the first period, while they amounted to 91.5% and 8% during the 2nd period. Overall frequency of ABO and Rhesus blood groups during the 2 periods were the following: O-positive 48% and 46%; A-positive 24% and 24.5%; B-positive, 17% and 17%; AB positive 4% and 4%; O negative 4% and 5%; A negative 2% and 2%; B-negative 1% and 2%; and AB negative, 0.23% and 0.32%. Comparison of our results with the other studies from the Kingdom and other nationalities is also presented. CONCLUSION Our results show that the most frequent blood group in Saudis is O-positive. Blood group A is observed at a lower frequency relative to values from Western populations, whereas a significant increase in blood group B combined with a slight increase in blood group AB was recorded. Knowledge of the frequencies of the different blood groups in Saudi Arabia is very important for Blood Banks and transfusion service policies. Knowledge of blood group phenotype distribution is also important for clinical studies (for example disease association), as well as for population studies.

Abstract
BACKGROUND Until recently ulcerative colitis (UC) was considered rare among Arabs. Information on its occurrence among Saudi is scant and limited to a few reports from urban populations. AIM OF STUDY to assess the frequency and clinico-pathologic pattern of this disease in a rural population in Gizan region, Saudi Arabia. METHODS thirty three patients found to have UC over a 4-year period in King Fahad Central Hospital were analyzed retrospectively. RESULTS there were 24 males and nine females patients with UC (ages ranged from 17-70 years, mean age 43.5 years). The commonest presenting symptoms were abdominal pain and diarrhea in 30 and 26 patients respectively. Extra-intestinal manifestations were rare, occurred in only two patients. Total or pancolitis was found in ten (30%) patients and it was severe in nine of them. The disease extended to the splenic flexure in eight (24.2%) of the patients. A total colectomy was required in one patient with severe pan-colitis and a focus of malignancy was present in the resected specimen. No patient died during the follow-up period that ranged from one to six years. CONCLUSION the study confirmed the occurrence of UC among the rural population studied. The male preponderance, the older age at presentation and relatively milder diseases appeared to be differentiating features from the pattern among western populations.

Abstract
Familial thrombocytosis (FT) has previously been described as an autosomal-dominant disorder with manifestations similar to those of sporadic essential thrombocythaemia. We studied an Arab family consisting of four brothers, aged 4-8 years, who had either sustained markedly elevated (> 1000 x 109/l) or moderately elevated (> 500 x 109/l) platelet counts, two healthy sisters and their parents who had normal platelet counts. The four brothers with FT had normal plasma thrombopoietin levels and are currently not presenting with any thrombotic or haemorrhagic complications. Mutation analysis at the thrombopoietin gene (THPO) of the affected family members failed to detect the intron 3 G-->C splice mutation that had been described as causing FT. In addition, segregation analysis using a polymorphic CA marker revealed completely discordant THPO alleles among the affected brothers. We postulate the existence of a new locus for FT whereby the disease is transmitted as a recessive, possibly X-linked trait.

Abstract
The objective of this study was to investigate the immunity against rubella in the obstetric population in Kuwait by testing 600 pregnant women at a prenatal clinic, using the haemagglutination inhibition technique. In addition, a comparison was made between this study and one done in 1978 at the same clinic; its relation to the vaccination programme is also discussed. 7.7% of the population under study were non-immune. Statistically significant effect was demonstrated for maternal age but not for parity and nationality. Though it has been almost 20 years since an intense rubella vaccination programme was implemented, the percentage of non-immune pregnant women has not decreased. In Kuwait, termination of pregnancy for congenital rubella syndrome is prohibited. As a result, it is recommended that women be screened and vaccinated at the time of marriage.

Abstract
OBJECTIVE The objectives of this study were to evaluate the usefulness of the middle cerebral artery to umbilical artery resistance index ratio (C/U ratio) as a predictor of adverse perinatal outcome, and to show that the absence of fetal umbilical artery end-diastolic velocity (AEDV) in SGA fetuses is associated with high morbidity and mortality. METHOD In this prospective study, color Doppler flow imaging was used for the estimation of the C/U ratio in fetuses that were small for their gestational age, in 70 singleton pregnancies between 29 and 42 weeks of gestation. The subjects were categorized into two groups, with Group A consisting of 35 small for gestational age (SGA) fetuses with a normal C/U ratio (1.05 or higher), and Group B comprising 35 SGA fetuses with an abnormal C/U ratio (below 1.05). RESULT The mean C/U ratio values for birth weight and gestational age were higher in group A than in group B. Fetuses born to mothers in group B stayed longer in the neonatal special care unit (NSCU), whereas the period from ultrasound examination to delivery was higher in the cases in group A. A higher percentage of mothers with an abnormal C/U ratio underwent cesarean section. Fetuses with an absent end-diastolic velocity of the umbilical artery had a higher morbidity. Three stillbirths occurred in fetuses with an absent end-diastolic velocity of the umbilical artery. CONCLUSION Our results suggest that the C/U ratio is a good predictor of neonatal outcome, and could be used to identify fetuses at risk of morbidity and mortality. Fetal umbilical artery AEDV with intrauterine growth restriction is associated with high perinatal morbidity and mortality.

Abstract
Proximate, mineral, fatty acid and cholesterol composition of eight traditional sweets commonly consumed in the Arab Gulf countries were determined. Four sweets were obtained from Bahrain, whereas the other sweets were obtained from Oman. Protein level ranged from 0.2 to 9.0%, while the fat content ranged from 7.9 to 18.0%. In general, the sweets were found to be high in energy content but poor in most minerals. Iron and zinc contents were low (less than 2 and less than 1 mg/100 g for iron and zinc, respectively). Cholesterol was high in four sweets (range from 10.6 to 20.4 mg/100 g), mainly because of the use of animal fat in preparation of these sweets. The fatty acids profiles showed that palmitic and oleic acids were predominant. One sweet (eggbaith) was found to be very high in linoleic (42%) and low in palmitic (9.6%) acids. The study showed that some traditional sweets are nutritious, while others should be consumed with moderation.

Abstract
The species composition of malaria vector mosquitoes belonging to the Anopheles gambiae complex (Diptera: Culicidae) from >40 localities in Sudan, representing most ecological situations, was determined by analysis of ovarian polytene chromosomes. Of 2162 females, 93% were identified as An. arabiensis Patton and 7% were An. gambiae Giles sensu stricto. No hybrids were found between the two species. Anopheles arabiensis occurred in all but two sites, whereas An. gambiae s.s. was effectively limited to the southernmost, more humid localities. For chromosomal paracentric inversions, the degree of polymorphism was low in An. gambiae s.s. (inversions 2La, 2Rb and 2Rd), higher in An. arabiensis (inversions Xe, 2Ra, b, bc, d1, s; 3Ra, d). Anopheles gambiae samples from Sudan were all apparently panmictic, i.e. they did not show restricted gene flow such as observed among West African populations (interpreted as incipient speciation). Chromosomal inversion patterns of An. gambiae in southern Sudan showed characteristics of intergrading Savanna/Forest populations similar to those observed in comparable eco-climatic situations of West Africa. Anopheles arabiensis was polymorphic for inversion systems recorded in West Africa (2Ra, 2Rb, 2Rdl, 3Ra) and for a novel 2Rs polymorphism, overlapping with inversion systems 2Rb and 2Rd1. Samples carrying the 2Rs inversion were mostly from Khashm-el-Girba area in central-eastern Sudan. In the great majority of the samples all polymorphic inversions were found to be in Hardy-Weinberg equilibrium. Sudan populations of An. arabiensis should therefore be considered as generally panmictic. Anopheles arabiensis shows more inversion polymorphism in west than in east African populations. Sudan populations have more evident similarities with those from westwards than those from eastwards of the Great Rift Valley. The possible influence of the Rift on evolution of An. arabiensis is discussed.

Abstract
Five novel polyvinyl chloride (PVC) matrix membrane sensors for the selective determination of sulbutiamine (SBA) cation are described. These sensors are based on molybdate, tetraphenylborate, reineckate, phosphotun gestate and phosphomolybdate, as possible ion-pairing agents. These sensors display rapid near-Nernstian stable response over a relatively wide concentration range 1x10(-2)-1x10(-6) M of sulbutiamine, with calibration slopes 28 32.6 mV decade(-1) over a reasonable pH range 2-6. The proposed sensors proved to have a good selectivity for SBA over some inorganic and organic cations. The five potentiometric sensors were applied successfully in the determination of SBA in a pharmaceutical preparation (arcalion-200) using both direct potentiometry and potentiometric titration. Direct potentiometric determination of microgram quantities of SBA gave average recoveries of 99.4 and 99.3 with mean standard deviation of 0.7 and 0.3 for pure SBA and arcalion-200 formulation respectively. Potentiometric titration of milligram quantities of SBA gave average recoveries of 99.3 and 98.7% with mean standard deviation of 0.7 and 1.2 for pure SBA and arcalion-200 formulation, respectively.

Abstract
Infection with parvovirus B19 during pregnancy is known to be associated with various fetal damage, such as aplastic anemia and hydrops fetalis. Our objective was to study the seroprevalence of parvovirus B19 in the obstetric population in Kuwait and to compare this with that in the adult population in other regions. Blood samples from 1047 pregnant women were used in this prospective study. Information regarding patient's age, parity, nationality and symptoms was obtained at the time of collection of the sample. Blood was tested for IgG and IgM antibodies specific for parvovirus B19 using the ELISA technique. The overall prevalence for IgG and IgM was 53.3 and 2.2%, respectively. IgG seropositivity was higher in non-Kuwaiti women, while IgM antibodies was more frequent in Kuwaiti women. A total of 17.4% of the acutely infected patients were symptomatic. Prevalence of parvovirus B19 infection in Kuwait is comparable with that in the other countries.

Abstract
Seasonal variation of temperature and humidity are said to influence the incidence of hypertensive disorders of pregnancy. The aim of this study was to determine if temperature and humidity exert any influence on the incidence of pregnancy-induced hypertension and preeclampsia in Kuwait. This is a retrospective study performed in the Maternity Hospital, Kuwait (MHK) in the years 1992-1994. Monthly distribution of all deliveries and those in which the patients had pregnancy-induced hypertension and preeclampsia were recorded. There are some studies including ours which do not show any significant correlation between meteorological factors and hypertensive disorders of pregnancy. We found that the incidence of pregnancy-induced hypertension per 1,000 deliveries was high in June when the temperature was very high and the humidity at its lowest. The reverse was true for the incidence of preeclampsia per 1,000 deliveries, which was high in November when the temperature was low and the humidity high.
