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
One hundred and twenty eight children suffering from leukaemia were admitted to King Fahd Hospital of the University in the Eastern Province of Saudi Arabia during the period of January 1982-December 1992. Acute lymphoblastic leukaemia was the most common whilst chronic granulocytic leukaemia the least common among the studied group.

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
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.
