Symptoms of migraine in the paediatric population by age group.

The revised criteria of the International Headache Society (IHS) for paediatric headache do not differentiate among age groups. This study aims to determine if different symptoms of migraine are specific or typical of different age groups of children. The files of 160 children (79 boys, 81 girls, mean age 10.39 +/- 3.71 years) with migraine treated at the paediatric headache clinic of a tertiary centre were reviewed. The diagnosis was based on the criteria of the IHS (ICHD-II). The patients were divided by age into three groups according to educational status, < or =6 years (preschool, group 1), >6 to < or =12 years (elementary school, group 2) and >12 to < or =18 years (secondary school, group 3), and compared by symptoms and signs. Symptoms of migraine with and without aura were also compared. There was no significant difference among the groups in rates of unilateral headache, phonophobia, photophobia, awakening pain, nausea or worsening of pain during physical activity. The parameters found to be statistically significant were dizziness and duration of migraine, and aura which increased with time. Frequency of attacks increased with age. The single statistically significant parameter found to be more frequent in younger age was vomiting. The statistically significant parameters of nausea and duration of migraine were more frequent in migraine with aura compared with migraine without aura. In conclusion, most of the migraine symptoms included in the 2004 recommendations of the IHS are not typical for specific paediatric age groups, probably because brain maturity is a continuous process. A familial history of migraine is a frequent finding among all age groups and should be considered in the paediatric criteria, especially in younger children in whom diagnosis is more difficult. Vomiting may help the diagnosis of migraine in young children with a familial history of migraine.

Recurrent facial nerve palsy in paediatric patients.

UNLABELLED: The aim of the study was to investigate the clinical presentation and prognosis of recurrent facial nerve palsy (RFNP) in children. The files of 182 patients referred to the Schneider Children's Medical Centre of Israel for neurological evaluation of isolated peripheral facial nerve palsy between October 1992 and December 1998 were reviewed. RFNP was found in 11 patients (9 females, 2 males), with an incidence of 6%. In two males, the aetiology was traced to Melkersson-Rosenthal syndrome and these patients were separated from the rest of the group. Three children had two episodes of facial nerve paresis which completely resolved clinically within several weeks. Six other children underwent electrophysiological studies. Two of the latter with residual neurological damage, and one child with abnormal blink reflex only, showed decreased facial nerve conduction velocity and abnormal blink reflex. Three children with complete recovery had disturbed blink reflex only with normal nerve conduction. Brain imaging studies as well as laboratory work-up were non-contributory in all cases. CONCLUSION: The frequency of recurrent facial nerve palsy in children was similar to that in adults. The most significant factors in the evaluation of recurrent facial nerve palsy are medical history and physical findings at diagnosis and after short follow-up. In our patients, electrophysiological studies did not have either clinical or prognostic significance. The rate of full clinical recovery is about 70%, lower than in Bell palsy.

Secondary enuresis: post-traumatic stress disorder in children after car accidents.

BACKGROUND: In our experience, secondary enuresis nocturna is a common complaint among children after a motor vehicle accident. However, as these children are often brought for examination as part of an insurance compensation claim, this complaint is not always reliable. OBJECTIVE: To describe a series of children in whom secondary enuresis occurred after a motor vehicle accident. METHODS AND RESULTS: Five children were brought to our clinic for evaluation of secondary nocturnal enuresis. Review of past history revealed a car accident preceding the onset of the enuresis. All but one had additional behavioral symptoms typical of post-traumatic stress disorder. Four children had evidence of head trauma, and one had psychological but no physical trauma. CONCLUSIONS: Nocturnal enuresis can occur after a motor vehicle accident due either to purely psychological trauma or organic head trauma. While nocturnal enuresis is generally attributed to organic causes, psychological mechanisms also play a significant role.

Delayed post-traumatic visual loss: a clinical dilemma.

A 16-year-old female presented with unilateral blindness in her right eye 2 months after blunt head trauma. Optic nerve edema was demonstrated by funduscopic examination, ultrasonography, and magnetic resonance imaging and failed to respond to medical treatment. Delayed post-traumatic blindness may be a severe complication of head trauma. The late appearance leads to delayed diagnosis and resulting unresponsiveness to treatment. Patients who experience head trauma that could involve the optic nerves should undergo ultrasonography of the optic nerves. An abnormal finding should be followed by an intensive evaluation to determine possible damage.

Comparative evaluation of cefixime versus amoxicillin-clavulanate following ceftriaxone therapy of pneumonia.

Preliminary results have recently shown that an early switch from parenteral antimicrobials to an oral substitute provides an effective means of treating pneumonia in pediatric patients. In a controlled randomized study, 62 children with community-acquired lobar/segmental pneumonia were selected to receive 8 days of cefixime or amoxicillin-clavulanate after an initial therapy of two doses of parenteral ceftriaxone. Enrollment criteria included: age 6 months to 5 years, fever > 38.5 degrees C, white blood cell (WBC) count > or = 15,000/ mm3, and lobar/segmental pneumonia on chest radiograph. Twenty-nine patients were randomized to receive oral cefixime and 33 to oral amoxicillin-clavulanate. The two groups were comparable in the following pretreatment parameters: age, duration of illness, temperature, mean WBC count, erythrocyte sedimentation rate, C-reactive protein, and need for hospitalization. Days of resolution of high fever, tachypnea, cough, grunting, and laboratory test abnormalities were similar in the two groups. Clinical response at the end of treatment showed cure, improvement, and failure in 97%, 3%, and 0%, respectively, in the cefixime group and in 88%, 6%, and 6%, respectively in the amoxicillin-clavulanate group (P = NS). We conclude that young children with community-acquired lobar/segmental pneumonia can be successfully treated with 2 days of parenteral ceftriaxone followed by 8 days of oral cefixime or amoxicillin-clavulanate.

Lymphedema as a presenting sign of toxocariasis.

Toxocariasis in children is usually an asymptomatic infection and those with clinical illness have non-specific systemic or local manifestations. We present a 24-month-old boy with bilateral lymphedema of the feet as the main clinical manifestation of toxocariasis. The child presented with limping and nonpitting edema of both feet. Laboratory investigation revealed leucocytosis of < 20,000/mm3 with a differential count of < 50% eosinophils. No other cause of edema was found. The ELISA for toxocariasis revealed a high titer of > or = 1:4,096. The limping and the lymphedema disappeared during the third week of his illness. We suggest that toxocariasis should be considered as a possible cause of lymphedema and eosinophilia in young children.

The importance of thyroglobulin levels in monitoring the treatment of congenital hypothyroidism.

We have previously reported on high thyroid-stimulating hormone (TSH) concentrations in clinically euthyroid children with congenital hypothyroidism (CH) undergoing appropriate treatment. Whether this TSH is biologically active or not is still unclear. It has been shown that ectopic thyroid tissue does not involute during thyroxine (T4) therapy and thus can continue to secrete thyroglobulin (Tg). This study was undertaken to determine whether the Tg levels in ectopic CH infants represent residual thyroid tissue stimulated by biologically active TSH and whether this Tg can be used to help monitor CH treatment. Among the 51 primary CH children (age 2-14 years) diagnosed and followed up by us, 28 had measurable Tg values (> 2 pmol/l) several years after the T4 treatment had been started. In 8 of the children, Tg was measured as early as the time of diagnosis and followed up for at least 3 years. The Tg levels decreased much more slowly than the TSH levels did, and secondary Tg rises were observed. By 5 months of age, all children had Tg levels less than 25 pmol/l. Although in some infants the Tg levels paralleled TSH behavior, in others the TSH-Tg correlation was not so obvious. In another group of 8 children who had high TSH values despite normal T4, the LT4 replacement dosage was increased by 60% for 1 week (from 3.5 +/- 0.2 to 5.5 +/- 0.5 micrograms/kg/day) in order to examine the TSH-Tg dependence.(ABSTRACT TRUNCATED AT 250 WORDS)

Nonketotic hyperosmolar coma in children.

Nonketotic hyperosmolar diabetic coma is well known in adults, but infrequently reported in children. This syndrome is associated with a 20-70% mortality rate. We report the successful treatment of a 12.5 year old girl with a hyperglycemic (1,800 mg/dl glucose) nonketotic hyperosmolar diabetic coma and summarize the reported cases in the literature.

Rambam-Hasharon syndrome of psychomotor retardation, short stature, defective neutrophil motility, and Bombay phenotype.

We describe 2 Arab patients, both offspring of unrelated consanguineous matings, with unusual facial appearance, severe mental retardation, microcephaly, cortical atrophy, seizures, hypotonia, dwarfism, and recurrent infections with neutrophilia. Neutrophil motility was markedly decreased but the opsonophagocytic activity was normal. Both patients lack the red blood cell (RBC) H antigen and manifest the Bombay (hh) phenotype. Familial endocardial fibroelastosis and familial tetralogy of Fallot segregated independently in one family. The occurrence of the same syndrome in 2 unrelated families suggests that the various aspects of the disorder are the pleiotropic effects of a single mutation. Homozygosity-by-descent for a deletion involving contiguous genes may explain the findings in this syndrome. Alternatively, a mutation which involves an ubiquitous GDP fucose donor rather than the enzyme (alpha 2-L-fucosyltransferase) or its substrate (glcNAc) may account for the pleiotropic manifestations in this syndrome.

Seborrheic skin and acne vulgaris as protective factors against the development of basal cell epithelioma.

This study was conducted in order to evaluate a possible protective role of seborrheic complexion and a history of acne on the development of basal cell epithelioma (BCE). For this purpose, 77 patients with this tumor were examined and asked to fill out a questionnaire. The questionnaire included demographic data and questions about skin type, eye and hair colors, sun exposure habits and a past history of acne. The nature, number and location of tumors, the texture of skin and acne scars were noted by a physician. A group of 93 age-, sex- and skin-color-matched patients served as controls. The results show a clear relationship between seborrheic features and a lower risk of developing BCE, after controlling for solar exposure using the Mantel-Haenszel summary measure. The same trend was found in patients with a history of acne. Whether ultraviolet light absorption by sebum, an anticancer activity of Propionibacterium acnes or other factors play a protective role against the development of BCE is as yet unclear.
