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.

Abstract
OBJECTIVE Aims of this study were to determine the IgG and IgM seropositivity to parvovirus B19 during the three trimesters of pregnancy. METHODS Initially, a total of 1,047 pregnant women were included in a prospective study. Blood samples were obtained from 343, 406 and 298 cases in the first, second and third trimesters, respectively. To study the incidence of seroconversion, a second sample of blood was obtained 2-4 weeks later from the first 100 cases, who were IgG and IgM negative in the first trimester. RESULTS The seroprevalence of parvovirus B19 IgG and IgM was 53.3% and 2.2%, respectively. The incidence of seroconversion was 16.5%. The rate of fetal loss was 15.4% in patients with acute infection, all of which occurred in the first two trimesters. CONCLUSIONS The percentage of IgG positive cases is significantly higher in first and second trimesters compared to the third trimester. The seroconversion rate was 16.5%.

Abstract
OBJECTIVES Clinical and genetic characterisation of families in the west of Scotland with familial hemiplegic migraine. METHODS Families with familial hemiplegic migraine were identified via probands attending the regional paediatric neurology and child development centre. All available family members were assessed clinically and genetic linkage studies for the known familial hemiplegic migraine gene locus on chromosome 19 were carried out on three families. RESULTS Seven unrelated kindreds with familial hemiplegic migraine were identified. Clinical information was obtained on 138 family members, 27 of whom fulfilled the International Headache Society criteria for familial hemiplegic migraine. Whereas the severity, duration, frequency, and temporal progression of acute hemiplegic migrainous attacks showed pronounced variability within and between families, and even in the same individual over time, no true clinical heterogeneity of the condition was apparent. Genetic linkage analysis gave results consistent with linkage to the familial hemiplegic migraine gene locus on chromosome 19p in one family. In the other two families, evidence against linkage was obtained. There was no significant clinical difference between these three families. CONCLUSIONS This study provides characterisation of the clinical features of familial hemiplegic migraine in a British population. Significant variability was found in the frequency and character of migraine attacks within and between families, and no true clinical heterogeneity was identified. On the other hand, further evidence for genetic heterogeneity of the condition was found.

Abstract
Rice based oral rehydration therapy (ORT) solutions have been shown to be superior to glucose oral rehydration salts (World Health Organisation (WHO) ORS) in reducing stool volume and duration of diarrhoea in children and adults. Rice based ORT has been used only sparingly in young infants, however, because of theoretical concerns about digestibility. A randomised controlled trial of rice based ORT (50 g rice and electrolytes identical to WHO ORS) and WHO ORS was carried out in 52 male infants less than 6 months old with moderately severe acute diarrhoea to evaluate efficacy and digestibility. Nineteen (70%) of 27 children who received rice based ORT and 18 (72%) of 25 children who received WHO ORS were treated successfully. The mean (SD) diarrhoeal stool output for the first 24 hours of treatment was significantly lower in the infants receiving the rice based ORT than in those receiving WHO ORS (101.0 (60.5) v 137.1 (74.6) g/kg). The stool output was also significantly less in the rice based ORT group in the second 24 hours. Infants in the rice based ORT group drank significantly less rehydration solution than infants in the WHO ORS group (mean (SD) 165.4 (77.4) v 217.9 (86.1) during the first 24 hours of treatment. There was no difference in the duration of diarrhoea between the groups. The volume of breast and formula feeding was similar in the two groups. No difference was seen in the frequency of finding reducing substances or acid pH in the stools of either group of children. The results suggest that rice based ORT is as effective as WHO ORS in infants with moderately severe diarrhoea and that rice based ORT is as well tolerated as WHO ORS in infants.

Abstract
Two types of polyvinyl chloride (PVC) matrix membrane electrodes responsive to the antimalarial drug chloroquine have been constructed, electrochemically evaluated, compared and used in pharmaceutical analysis. Type 1 is the classic PVC model with chloroquine-tetraphenylborate (TPB) sensor; Type 2 is a coated silver disk without internal filling solution. Both electrode types exhibited rapid linear potentiometric response to the logarithmic concentration of diprotonated chloroquine cation in the 10(-1) - 10(-6)M range with calibration slopes 28-30 mV/concentration decade over the pH range 1.8-6.2. These electrodes were sensitive enough to permit determination of chloroquine phosphate at concentrations as low as 5 microgram/mL with good accuracy and precision. Determination of chloroquine in various pharmaceutical preparations using direct potentiometry and potentiometric titration with NaTPB gave an average recovery of 98.8% of the nominal values (SD 0.5%). The Type 2 electrode was also assessed in a flow-through sandwich cell for flow injection analysis. Results were compared with data obtained by the U.S. Pharmacopeia method.

Abstract
Cord blood specimens from 513 normal Saudi neonates from the Eastern Province were screened for the deficiency of erythrocyte pyruvate kinase enzyme using the fluorescent spot test. The enzyme activity of the deficient specimens and 108 randomly selected samples was assayed spectrophotometrically. The results indicate that the incidence of this enzyme deficiency is 3.12% which is higher than that reported previously. The findings are compared with those reported by others and the possible factor responsible for the high incidence of this deficiency is discussed.

Abstract
A young woman presented with mild pyrexia and antepartal haemorrhage due to disseminated intravascular coagulation. She had pancytopenia in the peripheral blood and granulocytic maturation arrest at the promyelocyte stage in the bone marrow. Her urine and bone marrow grew Mycobacterium kansasii on culture. Antituberculous treatment eliminated the infection and restored the normality of bone marrow and peripheral blood.

Abstract
Hemoglobinopathies are a major public health problem in Saudi Arabia. We studied the effect of splenectomy in 16 Saudi Arabian children with compound hemoglobinopathies. Seven patients no longer require regular blood transfusions, and transfusion requirements were decreased by 30 to 60% in the other eight patients. Three patients whose heights and weights were below the 5th percentile before splenectomy reached the 25th percentile 1 year after the surgery. In spite of preoperative pneumococcal vaccination and the penicillin prophylaxis after the surgery, one patient died of Haemophilus influenzae Group B bacteremia, and three others had six episodes of pneumonia.

Abstract
The levels of glycated haemoglobin, fetal haemoglobin and methaemoglobin in 618 Saudi subjects were determined. A statistically significant decrease in the percentage of glycated haemoglobin was observed in all haemoglobinopathic groups studied in comparison to normal controls. However, there was no significant difference in the percentage of glycated haemoglobin in patients with sickle cell anaemia when compared with those sickle cell subjects who were also glucose-6-phosphate dehydrogenase deficient. This suggests that there is little survival advantage or disadvantage in the combination of glucose-6-phosphate dehydrogenase deficiency and sickle cell anaemia.

Abstract
Reference values have been established for erythrocyte glycosylated haemoglobin levels in a normal Saudi population and in subjects with various haematological disorders. The mean glycosylated haemoglobin levels (SE) were 7.28% (0.039) for normal, 6.04% (0.057) for G6PD deficient, 4.40% (0.081) for homozygous sickle cell, and 6.44% (0.109) for heterozygous sickle cell subjects. Values of 6.26% (0.103) and 4.75% (0.127) for glycosylated haemoglobin were determined for heterozygous and homozygous sickle cell subjects with G6PD deficiency, respectively. Statistical analysis of the data shows significant differences in the extent of glycosylation between G6PD deficient, HbSS and normal controls. Where possible the results are compared to values reported for other populations.

Abstract
A new "supply-demand" measure of family planning demand is compared with others commonly used to target prospective family planning clients. In analyses of data from six cross-sectional surveys the new measure consistently explains past contraceptive use better than the others. Time series analysis for two countries yields similar results. Family planning program officials may wish to consider exploring the use of this measure to target prospective clients.

Abstract
The first authentic case of African histoplasmosis from the Sudan is reported. The patient came from Dindir, along the southern part of the Blue Nile River. He had cutaneous and visceral leishmaniasis as well as the cutaneous form of African histoplasmosis. The latter was proved by culture and histopathology to be due to Histoplasma duboisii. The fungus was confined to the skin. H. duboisii may be more prevalent, and further studies in Dindir area are needed.
