Autosomal recessive microcephaly with neonatal myoclonic seizures: clinical and MRI findings.

We describe an infant who was born to a consanguineous couple of Palestinian origin. The patient had severe microcephaly, myoclonic seizures, hypsarrythmia, spasticity, hypertonicity, and profound mental retardation. A similar case was reported in another unrelated Palestinian family, suggesting that this condition may be endemic. The condition resembles early onset myoclonic seizures and spasticity described by Tolmie et al.: Am J Med Genet 27:583-594 [1987]. To the best of our knowledge, only four pairs of sibs have been described with this syndrome; however, to date no magnetic resonance imaging (MRI) findings were reported for this condition. We present the clinical and radiological findings in the patients, including the first report of MRI findings.

Colchicine-induced myoneuropathy in childhood.

UNLABELLED: Colchicine is used in the treatment of gouty arthritis, familial Mediterranean fever, amyloidosis, Behcet disease and dermatoses. Myoneuropathy is a rare side-effect reported either with intoxication or in elderly patients with chronic renal insufficiency causing elevated plasma drug levels. We report the first two cases of myoneuropathy in children, both taking appropriate doses of colchicine, and having normal renal function. The myoneuropathic changes were reversible after stopping treatment. The cause of colchicine myoneuropathy is unclear. CONCLUSION: In children treated with colchicine, neuromuscular phenomena of unknown aetiology may be related to the drug, even with a lack of intoxication or renal insufficiency.

Effectiveness and safety of inhaled corticosteroids in controlling acute asthma attacks in children who were treated in the emergency department: a controlled comparative study with oral prednisolone.

BACKGROUND: Inhaled corticosteroids have a greater antiinflammatory potency and fewer systemic effects than intravenous, intramuscular, or oral corticosteroids. However, their role in acute asthma has not been established. We prospectively investigated the efficacy and safety of inhaled corticosteroids in controlling moderately severe acute asthma attacks in children who were treated in the emergency department. METHODS: Children who were treated in the emergency department with moderately severe asthma attacks after receiving treatment with inhaled terbutaline were allocated by double-blind design to receive 1 dose of either 1600 micro(g) budesonide turbohaler or 2 mg/kg prednisolone. The pulmonary index score and peak expiratory flow rate were measured hourly for the first 4 hours. After discharge the children were treated with the same initial doses given 4 times daily, followed by a 25% reduction in dose every second day for 1 week. Parents recorded asthma symptoms and use of beta-2 agonists on a daily diary card. Serum cortisol concentration was measured at the end of weeks 1 and 3. RESULTS: Twenty-two children (11 in each group) with similar baseline parameters completed the study. There was a similar improvement in pulmonary index score and peak expiratory flow rate in the 2 groups. Children treated with budesonide showed an earlier clinical response than those given prednisolone, who also showed a decrease in serum cortisol concentration. CONCLUSION: In children with moderately severe asthma attacks who were treated in the emergency department, a short-term dose schedule of inhaled budesonide turbohaler, starting with a high dose and followed by a decrease over 1 week, is at least as effective as oral prednisolone, without suppressing serum cortisol concentration.

Rapid induction of clinical response with a short-term high-dose starting schedule of budesonide nebulizing suspension in young children with recurrent wheezing episodes.

BACKGROUND: There are no data currently available on the correct schedule for the initiation of treatment with nebulized suspension of budesonide in children with recurrent wheezing episodes. We compared the efficacy and safety of starting with a high dose followed by a stepwise decrease to a continuous low dose. METHODS: In a double-blind design, 42 children aged 6 months to 3 years were randomly allocated to receive either a high starting dose of 1 mg budesonide twice daily followed by a stepwise decrease of 25% every second day for 1 week (group A) or a low dose of 0.25 mg twice daily for 1 week (group B). Efficacy was assessed with daily symptom scores and the systemic effect of the corticosteroids with the adrenocorticotropic hormone test. RESULTS: The two groups were comparable for all parameters evaluated. During the first week of treatment, there was a significant decrease in asthmatic symptomatology only in group A: a 59% decrease for wheezing (p = 0.0001), 39% for diurnal cough (p = 0.036), and 39% for nocturnal cough (p = 0.04). Mean time to clinical response was 3.0 days in group A and 5.7 days in group B (p = 0.02). This early improvement was sustained for the rest of the follow-up period. The high dose starting schedule was not associated with any change in serum cortisol level. CONCLUSIONS: The administration of nebulized suspension of budesonide at a high starting dose schedule followed by a rapid (1 week) stepwise decrease yields a significant early improvement in asthma symptoms and causes no change in serum cortisol levels.

Scrotal involvement in Henoch-Schönlein purpura in children.

Different rates of scrotal involvement in Henoch-Schönlein purpura (HSP) have been reported. We assessed scrotal involvement in 86 children over a 20-year period: 10 patients suffered from scrotal involvement and 9 of them also had arthritis. The possible association between scrotal involvement and arthritis may help the physician in the differential diagnosis of atypical presentations.

Lidocaine as a diluent for administration of benzathine penicillin G.

OBJECTIVE: Benzathine penicillin G is recommended for secondary prophylaxis of rheumatic fever. Its main disadvantage is local pain and discomfort associated with the injection. Lidocaine as a diluent may reduce this discomfort. We compared the administration of benzathine penicillin G with two diluents; sterile water and lidocaine hydrochloride 1% for penicillin concentrations and pain of injection. DESIGN: In a randomized double blind, crossover trial, 18 children ages 11 to 19 years who required prophylactic treatment for rheumatic fever were randomly divided into two groups. One received an injection of benzathine penicillin G diluted with 3.2 ml of sterile water, followed 1 month later by an injection of benzathine penicillin G diluted in lidocaine hydrochloride 1%; the second group received the same regimen in the reverse order. Serum penicillin concentrations and subjective pain sensation were determined after each injection. RESULTS: Peak serum penicillin concentrations at 24 h after injection were similar for both preparations (0.100 microg/ml for water, 0.102 microg/ml for lidocaine), as were the other serum values measured throughout the month. After 28 days detectable concentrations (> or =0.020 microg/ml) were found in 44 and 291% of the subjects, respectively (P = 0.4). Urine penicillin concentrations on Day 28 were 1.81 +/- 0.25 and 2.31 +/- 0.25 microg/ml, respectively. The pain score immediately after the injection was significantly lower with the lidocaine than with the sterile water dilution. CONCLUSION: Use of lidocaine hydrochloride as a diluent for benzathine penicillin G does not change the penicillin concentration in body fluids and significantly reduces the pain of injection. We suggest the use of lidocaine hydrochloride 1% as a diluent for benzathine penicillin G.

Prolonged vaginal bleeding during central precocious puberty therapy with a long-acting gonadotropin-releasing hormone agonist.

OBJECTIVE: To describe our experiment with the treatment of GnRH-a in premenarchal girls with idiopathic central precocious puberty (CPP). PATIENTS AND METHODS: Twenty-eight girls, aged 6.5-11 years, with idiopathic central precocious puberty were treated every 28 days with an intramuscular depot gonadotropin releasing hormone agonist (GnRH-a) in an attempt to delay sexual maturation. RESULTS: Eight of the 28 (28.5%) developed vaginal bleeding after GnRH-a administration. Of these, prolonged vaginal bleeding of 11-13 days occurred in four girls, three recurrent episodes occurred in one during the second injection, and in one other girl the 4th episode occurred after 6 months of treatment. CONCLUSION: Uterine bleeding following GnRH-a treatment in premenarchal girls with CPP is common, and may be massive and recurrent, since most episodes resolved spontaneously and necessitated no further treatment, careful advice should be given to the girls and their families prior to treatment initiation, in an attempt to avoid unnecessary anxiety and achieve better compliance.

Treatment of herpes simplex gingivostomatitis with aciclovir in children: a randomised double blind placebo controlled study.

OBJECTIVES: To examine the efficacy of aciclovir suspension for treating herpetic gingivostomatitis in young children. DESIGN: Randomised double blind placebo controlled study. SETTING: Day care unit of a tertiary paediatric hospital. SUBJECTS: 72 children aged 1-6 years with clinical manifestations of gingivostomatitis lasting less than 72 hours; 61 children with cultures positive for herpes simplex virus finished the study. MAIN OUTCOME MEASURES: Duration of oral lesions, fever, eating and drinking difficulties, and viral shedding. INTERVENTION: Aciclovir suspension 15 mg/kg five times a day for seven days, or placebo. RESULTS: Children receiving aciclovir had oral lesions for a shorter period than children receiving placebo (median 4 v 10 days (difference 6 days, 95% confidence interval 4.0 to 8.0)) and earlier disappearance of the following signs and symptoms: fever (1 v 3 days (2 days, 0.8 to 3.2)); extraoral lesions (lesions around the mouth but outside the oral cavity) (0 v 5.5 days (5.5 days, 1.3 to 4.7)); eating difficulties (4 v 7 days (3 days, 1.31 to 4.69)); and drinking difficulties (3 v 6 days (3 days, 1.1 to 4.9)). Viral shedding was significantly shorter in the group treated with aciclovir (1 v 5 days (4 days, 2.9 to 5.1)). CONCLUSIONS: Oral aciclovir treatment for herpetic gingivostomatitis, started within the first three days of onset, shortens the duration of all clinical manifestations and the infectivity of affected children. Further studies are needed to evaluate the ideal dose and length of treatment.

A new classification for pericarditis associated with meningococcal infection.

UNLABELLED: Acute meningococcal pericarditis is a rare clinical disorder. Our review of the literature disclosed that current classifications are confusing since they fail to differentiate between two distinct criteria: time and causality. We suggest a new classification of the various states of meningococcal pericarditis on the basis of the pathophysiological process: disseminated meningococcal disease with pericarditis (purulent, culture-positive, associated with meningococcal bacteraemia); isolated meningococcal pericarditis (purulent, culture-positive but without signs of meningeal or other clinical systemic involvement); and reactive meningococcal pericarditis (immunological, late-onset, culture-negative, resembling post-viral pericarditis). It is essential that clinicians recognize the various states of the disease, since they differ in natural history, treatment and prognosis. CONCLUSION: From personal experience and a literature review it emerges that meningococcal pericarditis should be classified as: (1) Pericarditis as local manifestation of disseminated meningococcal disease; (2) isolated meningococcal pericarditis; (3) reactive (immunopathic) meningococcal pericarditis.

Intramuscular ceftriaxone compared with oral amoxicillin-clavulanate for treatment of acute otitis media in children.

UNLABELLED: Two hundred and fifteen children aged 4 months 6 years with acute otitis media (AOM) were randomized to be treated either by a single i.m. injection of ceftriaxone, 50 mg/kg, with a second dose in the event of unsatisfactory response after 48 h or a history of recurrent AOM (109 patients) or amoxicillin clavulanate 12.5 mg tid (106 patients). The failure rate was similar in children treated by ceftriaxone and amoxicillin clavulanate, 4.6% and 4.7%, respectively (standard error for intergroup difference -2.87%, 95% confidence interval -5.62% to 5.87%). No significant differences between the groups were found in the dynamics of the resolution of the acute symptomatology, otoscopy findings, relapse rate at 30 days or tympanographic evidence of middle ear effusion at the scheduled visits on days 30, 60 and 90. Recurrence of AOM between days 31 and 90 was observed significantly in more children treated with amoxicillin clavulanate than with ceftriaxone--25 out of 84 (29.4%) versus 11 out of 81 (13.6%) (P = 0.012). CONCLUSION: Ceftriaxone injection(s) is as efficient at least as 10-day oral amoxicillin clavulanate for treatment of acute otitis media in children. Although not recommended as routine, ceftriaxone can be considered in the management of acute otitis media under special circumstances, particularly in cases when the ability to tolerate or absorb oral drugs is compromised, in children refusing or unable to take oral therapy or when the compliance is questionable.

Congenital intractable diarrhea of infancy in Iraqi Jews.

We report on five patients who presented with intractable diarrhea starting during the first days of life. The patients belonged to four families of Iraqi Jewish origin. Autosomal recessive inheritance is suggested by parental consanguinity in three families and recurrence in another sib in one family. The patients were all born after uneventful pregnancy and labor, with birth weight in the normal range. There were no dysmorphic features. Three patients were breast fed. Diarrhea started between the first and eighth day of life. Diarrhea was of the secretory type. No pathogen was cultured from the stool. Jejunal biopsies performed on all patients ranged from normal to severe partial villous atrophy. The patients received different drug regimens with no beneficial effect and all are dependent on TPN. These findings and the common ethnic origin of the patients suggest that these patients have the same syndrome of congenital intractable diarrhea. No similar cases are known in other ethnic groups in Israel, suggesting a possibility of high gene frequency among the Jews of Iraqi origin.

Coma with abnormal movements and prolonged cognitive disturbances: a new subset of acute encephalopathy.

We describe two children who presented with an acute encephalopathy preceded by a prodromal illness. The disease was marked by an active phase of coma or confusion with abnormal motor movements, followed by a recovery phase with a rapid return of motor function and a gradual improvement in speech and social behavior. No cause was found. These may be additional representative cases of a new syndrome of encephalopathy which is characterized by a distinctive course and a relatively good prognosis.
