Ceftriaxone-induced haemolytic anaemia in a child with no immune deficiency or haematological disease.

A 5-year-old girl, with no underlying immune deficiency or haematologic disease, was treated with ceftriaxone for a urinary tract infection. After receiving ceftriaxone intramuscularly, massive haemolytic anaemia developed. Laboratory studies showed the presence of an antibody against ceftriaxone, and the findings reflected immune complex type haemolysis. High-dose corticosteroids appeared to be effective therapeutically.

Evaluation of laboratory tests in dehydrated children with acute gastroenteritis.

OBJECTIVE: The aim of the present study was to demonstrate the utility of laboratory tests in predicting dehydration severity. METHODOLOGY: We evaluated retrospectively 168 dehydrated children aged 1-21 months with acute gastroenteritis. The degree of dehydration in each patient was calculated as the percentage change in weight from admission to after rehydration. The associations between degree of dehydration, urea, bicarbonate and serum sodium were examined. RESULTS: Dehydration severity was significantly related to concentrations of urea (P < 0.00001) and bicarbonate (P = 0.01), but not to serum sodium or age. Children were divided into three groups on the basis of blood urea: (i) normal (< 6.7 mmol/L or < 40 mg/dL); (ii) intermediate (6.8-16.6 mmol/L); and (iii) high (>or=16.7 mmol/L or >or=100 mg/dL). Groups 1 and 3 had statistically significant associations with the degree of dehydration and combining the urea groups with plasma bicarbonate levels enhanced the accuracy of predictions. Group 1 had only mild to moderate dehydration, but if bicarbonate was 15 mmol/L or higher, there was a positive predictive value (PPV) of 93% for mild dehydration. Group 3 had moderate to severe dehydration, but if bicarbonate was 15 mmol/L or higher, moderate dehydration could be predicted (PPV 100%). Sixty per cent of mildly dehydrated children (32/53) had low bicarbonate, but only 7% (2/29) with bicarbonate 15 mmol/L or higher had severe dehydration. Serum sodium did not have any significant association with the degree of dehydration, or the levels of bicarbonate or urea. CONCLUSIONS: The results suggest that serum urea and bicarbonate concentrations can be helpful in the estimation of fluid deficit independently from serum sodium concentration, and may be considered to be adjuncts to clinical evaluation in assessing the degree of dehydration.

Efficacy of long duration resuscitation and magnesium sulphate treatment in amitriptyline poisoning.

A single dose of cyclic antidepressants leads to death in childhood. Myocardial depression and ventricular arrhythmia are the severe side effects in cyclic antidepressant overdose. A 23-month-old boy was brought to hospital because 36 mg/kg of amitriptyline had been taken. Cardiopulmonary resuscitation was applied for 70 minutes due to cardiac and respiratory arrest. Circulation was restored after resuscitative efforts. However, ventricular tachycardia was detected which did not respond to lidocaine, bicarbonate and cardioversion treatment. Magnesium sulphate treatment was started and cardiac rhythm normalized. No side effects were observed. The duration of resuscitation should be extended in cases of cardiopulmonary arrest secondary to tricyclic antidepressants intoxication. It should be continued at least for 1 hour. Magnesium sulphate was found to be extremely effective in a case of amitriptyline intoxication refractory to treatment.

A rare cause of intracranial hemorrhage: factor X deficiency.

Congenital factor X deficiency is a rare inherited coagulation disorder, characterized by prolonged prothrombin time and partial thromboplastin time. For the definite diagnosis, specific factor X level should be investigated. We describe a patient with factor X deficiency who had intracranial hemorrhage. Hematologic tests showed prolonged prothrombin time, partial thromboplastin time, and a factor X level of 5%. The patient's hemorrhage resolved with fresh frozen plasma replacement. In this article, we discuss the clinical features and management of factor X deficiency.

Acute childhood hemiplegia associated with chickenpox.

Although primary varicella-associated central nervous system complications and herpes zoster ophthalmicus with delayed hemiplegia are well known, and chickenpox is a common infection, cerebral vasculopathy associated with chickenpox has only been described recently. We report the case of an 18-month-old girl who developed a right hemiplegia 10 days after the onset of a primary varicella infection. She has the shortest latent interval in the literature. Cranial computed tomography and magnetic resonance imaging suggest an infarction involving the left putamen and internal capsule. Magnetic resonance angiography is normal. Possible causes of acute infantile hemiplegia are excluded. Neurologic signs gradually improve without any specific treatment. A review of the literature is also presented.

Ten steps for successful breast-feeding: assessment of hospital performance, its determinants and planning for improvement.

This paper discusses results from a project which aims to document the maternity hospital practices in istanbul within the context of Ten Steps for Successful Breastfeeding. Instruments developed for use in hospital level implementation of the WHO/UNICEF baby friendly hospital initiative were used in five hospitals (two public and three private). No hospital was implementing all Ten Steps. A core hospital team on lactation management and a sufficient number of health personnel skillful in breastfeeding counselling and adequate delivery room conditions are required to implement the Ten Steps. It is very difficult to provide these conditions in public hospitals with an excessive patient load. On the other hand, the fee for service system and the policy of changing practices according to the wishes of the clients can also become barriers to successful breastfeeding, as may occur in some private hospitals.

The impact of systematic use of oral rehydration therapy on outcome in acute diarrheal disease in children.

A review of our experience with diarrheal disease (DD) at the University of Istanbul Children's Hospital in Capa, covering the years 1987 to 1989, is presented in this paper. DD is one of the most common conditions encountered among patients presenting to the outpatient clinic (5.9% of all cases). The majority of DD cases were in the four- to 12-month age group. During the surveillance period, summertime peaks in DD were observed, suggesting an increase in bacterial infection. Out of 8749 cases of DD, 5.2% showed severe dehydration. Rates of hospitalization for DD did not show any differences over the three years. However, mortality from DD significantly decreased from 1.15 to 0.57% during this three-year period. This was attributed to more rational use of oral rehydration solutions, as a result of the close monitoring and recording of findings introduced by the protocol of this study. Malnutrition, sepsis, pneumonia, and other severe systemic diseases were found to be the most important risk factors affecting hospitalization and mortality rates. Infants, especially those under three months, had the highest risk for hospitalization and mortality.

Experiences of a health team working in a new urban settlement area in Istanbul.

A project aiming at creating a model for comprehensive maternal and child health care for urban underdeveloped areas was started in a new settlement area of migrants in the vicinity of Istanbul. The project had an impact on health care status, particularly among infants and children, but the results indicated that more effort was needed to reach the mothers. It was noted that building space and the appearance of the work place influenced the prestige of the team. Absentee problems could be partly surmounted by repeated home visits. Based on this experience, it was concluded that health services in underdeveloped areas need to be supported by non medical personnel to act as home visitors and as mediators between the community and the health team. It was also concluded that an established recording system to include both clinical data and attendance is needed to define the cases who need special care.

Intraspinal hemorrhage in a child with factor XIII deficiency.

The rarity of spinal cord injuries and hemorrhages and of fibrin-stabilizing factor XIII deficiency during childhood has induced us to report the case of this two-year-old boy with factor XIII deficiency who presented with cervical intraspinal hemorrhage between the C4 and C7 levels as well as paraplegia presumably following a minor trauma. The findings in this patient, who was brought in two weeks after the appearance of the first symptoms, indicate the importance of early diagnosis and early intervention to minimize the extent of the damage from the injury in such cases. The case also points to the need for close follow-up of patients with factor XIII deficiency for CNS bleeding.

An educational intervention on promotion of breast feeding.

This study was designed to search for an effective method to promote exclusive breast feeding among Turkish city women delivering in hospitals. Four hundred and forty-two primiparae with uncomplicated deliveries and with healthy infants with birthweights of greater than 2500 g were exposed to a group educational session on breast feeding after birth, followed by one repeat session at home. Four hundred and ninety-nine women served as controls. All homes were visited monthly for 6 months by independent observers and data relevant to the feeding of the infants were collected. Weight measurements of 176 infants were taken at age 4 months. The study and control mothers were similar in sociodemographic characteristics which reflected a low socio-economic/educational background but relatively good housing conditions. Although significant differences in frequency of exclusive breast feeding were found between the study and control groups, the impact of the intervention was much lower than our expectations and short-lived. Type of feeding was not related to sex or birthweight of the infant, nor to maternal variables. Weight at age 4 months was within normal limits and similar in the study and control groups. It was concluded that lack of up-to-date information on infant feeding was the main obstacle to breast feeding in urban groups in Turkey, and that the impact of an educational intervention limited to the first week after delivery was lost within the first 2 months.

An educational intervention on promotion of breast feeding complemented by continuing support.

The study, aiming to document the effect of continued support for mothers on frequency of exclusive breast feeding, was carried out by inclusion of breast feeding counselling in the context of well-baby care. One hundred and forty-six mothers who had been exposed to two educational sessions on breast feeding after delivery were given appointments to bring their baby to the paediatric hospital for well-baby care. The mother-infant pairs were followed by the same two residents for 4 months. Mean number of visits was six. A conscious effort was made during all visits to influence the mothers and their close relatives towards exclusive breast feeding. It was observed that in a large proportion of the infants, breast milk was being supplemented with water at the time of the first visit and no further effort was made to change this traditional behaviour. Comparison of the results with a group of mothers who had been exposed to similar educational sessions after delivery but without further support showed a striking increase in frequency of exclusive breast feeding (breast milk and water) in the supported group.
