Summary:Purpose: We conducted a controlled study to investigate the relation of iron status and first febrile seizure (FFS).Methods: Measures of iron sufficiency including hemoglobin concentration (HB), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and plasma ferritin (PF) were prospectively measured in 75 children with FFS and compared with 75 controls matched for age and sex with febrile illnesses without convulsions.Results: Mean ferritin level was significantly lower in cases with FFS (29.5 ± 21.3 g/L) than in controls (53.3 ± 37.6 g/L) with p ‫ס‬ 0.0001. The proportion of subjects with a PF level Յ30 g/L was significantly higher among children with FFS (49 of 75 vs. 24 of 75) than in controls (p ‫ס‬ 0.000). Mean levels of HB, MCV, and MCH also were lower among FFS cases, but differences failed to attain statistical significance. A higher proportion of cases with FFS had an HB <110 g/L, MCV <72 fL, and MCH <24 pg than did the controls, but the differences were not statistically significant. There were no statistically significant differences between the cases and the controls in the mean peak temperature on admission, types of underlying illness, or family history of epilepsy and of febrile convulsion.Conclusions: PF level was significantly lower in children with FFS than in the reference group, suggesting a possible role for iron insufficiency in FFS. Key Words: Iron status-First febrile seizure.Febrile seizures (FSs) are the most common type of seizures, occurring in 2-5% of all children (1). Because of their association with later epilepsy, recent studies have attempted to identify their risk factors (2,3), including family history of febrile convulsions or epilepsy, perinatal factors, features of the acute underlying illnesses accompanying the FS, and the temperature peak. Pisacane et al. (4) reported that anemia was more common in children younger than 2 years with febrile seizures (FSs), whereas, in contrast, Kobrinsky et al. (5) reported that iron deficiency raises the threshold for seizures. Iron is involved in the metabolism of several neurotransmitters, and monoamine and aldehyde oxidases are reduced in iron-deficiency anemia (6), which is common during the second and third years of life, and has variably been associated with behavioral and developmental disturbances (7). In the present study, we focus on the assessment of the relation, if any, of iron status with FFS. PATIENTS AND METHODS Children with first febrile seizure (FFS) admitted to the Departments of Pediatrics, Princess Rahma and KingHussein Hospitals, between January and December 2000, were considered for inclusion in the study. FS was defined as an event in infancy or childhood, usually occuring between ages 3 months and 6 years, associated with fever but without evidence of intracranial infection or other defined causes of seizures. A single seizure of <15 min duration in the presence of fever without focal features was defined as a simple FS, whereas seizures were defined as complex if they lasted >15 min, had...

Environmental exposure to tobacco smoke and contaminants from unvented cooking stoves has been linked to impaired pulmonary function and respiratory diseases. These risk factors exist to a greater extent in developing countries and, in the case of exposure to tobacco smoke, they are reported to be increasing. In this study, pulmonary function studies were performed on 1905 children in Jordan. The effect of exposure to these environmental factors on respiratory function was analyzed. A significant negative impact was found with regard to environmental exposure to both passive smoking and wood and kerosene unvented cooking stoves. The mean values of lung function in children exposed and not exposed to passive smoking were, respectively, FVC (L): 1.29-1.49; FEV1 (L): 1.2-1.4; FEF25-75 (L/S): 1.84-2.24; PEFR (L/S): 2.6-3.21, and to wood and kerosene were FVC (L): 1.02-1.32; FEV1 (L): 0.91-1.25; FEF25-75 (L/S): 1.24-1.86; PEFR (L/S): 1.67-2.64. This is a major problem in developing countries because of the increasing incidence of smoking and the high exposure to pollution risk factors.

A better understanding of the demographics of these diseases has the potential to aid in the more efficient utilization of health care resources and improved planning and provision of health care services.

1. The effect of okadaic acid and sodium fluoride on swelling- and N-ethylmaleimide (NEM)-stimulated KCl cotransport was examined in blood cells from homozygote sickle cell anaemia patients. 2. Blood was drawn into heparin or EDTA by vein puncture from sickle cell patients previously diagnosed in the haematology clinics of Princess Badee'a Teaching Hospital. A standard method for measuring flux by using radioactive rubidium was used. 3. Okadaic acid strongly inhibited swelling-stimulated KCl cotransport if added before swelling. Okadaic acid and sodium fluoride added before NEM inhibited the activation of transport by NEM. Okadaic acid added after NEM did not inhibit transport. 4. The inhibition of the effects of NEM by okadaic acid and sodium fluoride indicates that activation of the flux by NEM requires the action of phosphatase.
