Background: The purpose of this study was to review the outcomes associated with different surgical treatments in the management of suppurative flexor tenosynovitis (SFT). Methods: Patients treated by open drainage (OD) through a single incision and closed catheter irrigation (CCI) of the tendon sheath were evaluated from 2003 to 2009 at a single institution. Variables examined included culture results, time to surgery, duration of hospitalization and antibiotic therapy, pain, reoperation, and functional outcomes were recorded. Statistical analyses used included parametric and nonparametric t tests. Results: Twenty-four patients were treated for SFT with a mean follow-up of 3 ± 2 years. There were 13 (100%) males in the OD group compared to 8 (72%) males within the CCI group. Ninety-two percent of patients who underwent OD and 100% who underwent CCI reported none or mild pain. There were no differences between the 2 groups with regard to functional outcome scores. Factors leading to worse functional outcomes included prolonged time to receiving antibiotics and Staphylococcus aureus infection. Smokers required prolonged antibiotic treatment compared to nonsmokers. Accounting for planned returns to the operating room, there was no difference in reoperation rates between the OD or CCI groups. Conclusions: Surgical treatment of SFT with either OD or CCI resulted in similar outcomes for pain, function, and need for reoperation. Factors that lead to poor outcomes include S aureus culture, prolonged time to antibiotics, and smoking.

Febrile infection‐related epilepsy syndrome (FIRES) is a devastating epileptic encephalopathy with limited treatment options and an unclear etiology. Anakinra is a recombinant version of the human interleukin‐1 receptor antagonist used to treat autoinflammatory disorders. This is the first report of anakinra for treatment of a child with super‐refractory status epilepticus secondary to FIRES. Anakinra was well tolerated and effective. Cerebral spinal fluid analysis revealed elevated levels of proinflammatory cytokines before treatment that normalized on anakinra, suggesting a potential pathogenic role for neuroinflammation in FIRES. Further studies are required to assess anakinra efficacy and dosing, and to further delineate disease etiology. Ann Neurol 2016;80:939–945

ObjectiveTo determine time trends in the incidence and survival of polymyalgia rheumatica (PMR) over a 15‐year period in Olmsted County, Minnesota, and to examine trends in incidence of PMR in the population by comparing this time period to a previous incidence cohort from the same population base.MethodsAll cases of incident PMR among Olmsted County, Minnesota residents in 2000–2014 were identified to extend the previous 1970–1999 cohort. Detailed review of all individual medical records was performed. Incidence rates were age‐ and sex‐adjusted to the US white 2010 population. Survival rates were compared with the expected rates in the population of Minnesota.ResultsThere were 377 incident cases of PMR during the 15‐year study period. Of these, 64% were female and the mean age at incidence was 74.1 years. The overall age‐ and sex‐adjusted annual incidence of PMR was 63.9 (95% confidence interval [95% CI] 57.4–70.4) per 100,000 population ages ≥50 years. Incidence rates increased with age in both sexes, but incidence fell after age 80 years. There was a slight increase in incidence of PMR in the recent time period compared to 1970–1999 (P = 0.063). Mortality among individuals with PMR was not significantly worse than that expected in the general population (standardized mortality ratio 0.70 [95% CI 0.57–0.85]).ConclusionThe incidence of PMR has increased slightly in the past 15 years compared to previous decades. Survivorship in patients with PMR is not worse than in the general population.

AbstractIntroductionAfrican Americans' (AAs) late‐onset Alzheimer's disease (LOAD) genetic risk profile is incompletely understood. Including clinical covariates in genetic analyses using informed conditioning might improve study power.MethodsWe conducted a genome‐wide association study (GWAS) in AAs employing informed conditioning in 1825 LOAD cases and 3784 cognitively normal controls. We derived a posterior liability conditioned on age, sex, diabetes status, current smoking status, educational attainment, and affection status, with parameters informed by external prevalence information. We assessed association between the posterior liability and a genome‐wide set of single‐nucleotide polymorphisms (SNPs), controlling for APOE and ABCA7, identified previously in a LOAD GWAS of AAs.ResultsTwo SNPs at novel loci, rs112404845 (P = 3.8 × 10−8), upstream of COBL, and rs16961023 (P = 4.6 × 10−8), downstream of SLC10A2, obtained genome‐wide significant evidence of association with the posterior liability.DiscussionAn informed conditioning approach can detect LOAD genetic associations in AAs not identified by traditional GWAS.
