Management of recurrent tonsillitis in children

Objective

To compare azithromycin (AZT) and benzathine penicillin (BP) in the treatment of recurrent tonsillitis in children.

Treatment of severe malnutrition with 2-day intramuscular ceftriaxone vs 5-day amoxicillin

BACKGROUND: Systemic antibiotics are routinely prescribed for severe acute malnutrition (SAM). However, there is no consensus regarding the most suitable regimen. In a therapeutic feeding centre in Khartoum, Sudan, a randomised, unblinded, superiority-controlled trial was conducted, comparing once daily intramuscular injection with ceftriaxone for 2 days with oral amoxicillin twice daily for 5 days in children aged 6-59 months with SAM. METHODS: Commencing with the first measured weight gain (WG) following admission, the risk difference and 95% confidence interval (95% CI) for children with a WG > or = 10 g/kg/day were calculated over a 14-day period. The recovery rate and case fatality ratio (CFR) between the two groups were also calculated. RESULTS: In an intention-to-treat analysis of 458 children, 53.5% (123/230) in the amoxicillin group and 55.7% (127/228, difference 2.2%, 95% CI -6.9-11.3) in the ceftriaxone group had a WG > or = 10 g/kg/day during a 14-day period. Recovery rate was 70% (161/230) in the amoxicillin group and 74.6% (170/228) in the ceftriaxone group (p=0.27). CFR was 3.9% (9/230) and 3.1% (7/228), respectively (p=0.67). Most deaths occurred within the 1st 2 weeks of admission. CONCLUSION: In the absence of severe complications, either ceftriaxone or amoxicillin is appropriate for malnourished children. However, in ambulatory programmes, especially where there are large numbers of admissions, ceftriaxone should facilitate the work of medical personnel.     

Novel KCNV2 mutations in cone dystrophy with supernormal rod electroretinogram

PURPOSE: To describe patients with cone dystrophy and supernormal rod electroretinogram (ERG) and search for mutations in the recently described KCNV2 gene. DESIGN: Clinical and molecular study. METHODS: Patients from three families originating from France, Morocco, and Algeria had standard ophthalmologic examination and color vision analysis, Goldmann perimetry, International Society for Clinical Electrophysiology of Vision (ISCEV) protocol in accordance with ERG testing, autofluorescence evaluation, and optical coherence tomography 3 scanning. The two coding exons of KCNV2 were polymerase chain reaction amplified and sequenced. RESULTS: All patients had the characteristic features of supernormal, delayed rod ERG responses at the highest levels of stimulation and markedly reduced cone responses. In the French family, two affected sisters were compound heterozygotes for the recurrent c.1381G>A (Gly461Arg) mutation and for a novel c.442G>T (Glu148Stop) mutation. In the Moroccan family, affected members were homozygotes for the novel c.1404delC mutation (His468fsX503) and in the Algerian family, the proband was homozygote for the novel c.1001delC mutation (Ala334fsX453). In the three families, parents were unaffected heterozygote carriers. None of the mutations were present in 50 control chromosomes. CONCLUSIONS: The three novel truncative mutations are likely to be null mutations leading to loss of function, with no difference in the phenotype presentation. Amino acid changes are found exclusively in the N-terminal fragment of the protein and in the P-loop, indicating the importance of those regions for the function of the KCNV2 protein.     

Isolated synovial chondromatosis of the subacromial bursa: report of a new case and review of the literature

Synovial chondromatosis is a rare metaplasia of the synovium of unknown etiology that may involve occasionally the subacromial bursa. We report a new case diagnosed by ultrasound in a 30-year-old man and we present pathogenetic, diagnostic and therapeutic features of this disease with a literature review.
