Mass distribution of a single dose of oral azithromycin for trachoma was associated with increased circulation of macrolide-resistant S. pneumoniae carriage among young children in the 6 months following treatment. It is crucial that changes in antibiotic resistance patterns and their clinical significance in the treatment of severe pediatric infections be assessed in future MDA trials.

BackgroundLyme disease, the most common vector-borne infection in North America, is increasingly reported. When the characteristic rash, erythema migrans, is not recognized and treated, delayed manifestations of disseminated infection may occur. The accuracy of diagnosis and treatment of early Lyme disease in the community is unknown.MethodsA retrospective, consecutive case series of 165 patients presenting for possible early Lyme disease between August 1, 2002 and August 1, 2007 to a community-based Lyme referral practice in Maryland. All patients had acute symptoms of less than or equal to 12 weeks duration. Patients were categorized according to the Centers for Disease Control and Prevention criteria and data were collected on presenting history, physical findings, laboratory serology, prior diagnoses and prior treatments.ResultsThe majority (61%) of patients in this case series were diagnosed with early Lyme disease. Of those diagnosed with early Lyme disease, 13% did not present with erythema migrans; of those not presenting with a rash, 54% had been previously misdiagnosed. Among those with a rash, the diagnosis of erythema migrans was initially missed in 23% of patients whose rash was subsequently confirmed. Of all patients previously misdiagnosed, 41% had received initial antibiotics likely to be ineffective against Lyme disease.ConclusionFor community physicians practicing in high-risk geographic areas, the diagnosis of Lyme disease remains a challenge. Failure to recognize erythema migrans or alternatively, viral-like presentations without a rash, can lead to missed or delayed diagnosis of Lyme disease, ineffective antibiotic treatment, and the potential for late manifestations.

BackgroundFecal impaction (FI) is a common problem in the elderly and other at-risk groups, such as patients with a neuro-psychiatric disease. It has been associated with medical problems and high morbi-mortality. A systematic review of this topic might be useful to improve the knowledge in this area and helpful to make an appropriate and early diagnosis.MethodsA PubMed systematic search was performed using relevant keywords. Case reports published in English, Spanish or French till June 2014 were included if they had a diagnosis of FI and a medical complication secondary to it. Each case was classified based on its principal complication. The main objective is to create a classification of FI complications based on published clinical cases.Results188 articles met inclusion criteria, comprising 280 clinical cases. Out of the total, 43,5 % were over 65 years old, 49 % suffered from chronic constipation, 29 % had an underlying neuropsychiatric disease and 15 % were hospitalised or institutionalised. A total of 346 medical complications secondary to FI were collected. They were divided according to gastrointestinal tract involvement and then classified based on their anatomical and pathophysiological mechanism into three groups: Complications secondary to fecaloma effect on the intestinal wall (73.4 %), on the intestinal lumen (14 %) and on adjacent structures (12.6 %).ConclusionsFI causes complications that might be fatal. The elderly, underlying neuropsychiatric disease and hospitalised or institutionalised patients integrate the high-risk group in which FI must be suspected. The first FI complications classification is presented to improve the knowledge about this entity.

MDA resulted in significantly increased prevalence of macrolide resistance in E. coli. Although MDA is effective for trachoma elimination, it has costs; it is essential to monitor antimicrobial resistance following MDA.

Mass distribution of a single dose of oral azithromycin for trachoma is associated with a significant short-term reduction in ALRI morbidity among young children.
