Neutrophilic Panniculitis in a child with MYSM1 deficiency

Neutrophilic panniculitis (NP) with myelodysplasia has been described in adults but not in children. We report a case of NP associated with myelodysplasia in a child with MYSM1 deficiency, a newly described syndrome with primary immunodeficiency (PI), bone marrow failure, and developmental aberrations.     

Relationship Between Depression and/or Anxiety and Hospital Readmission Among Women After Childbirth

ObjectiveTo examine the relationship between depression and/or anxiety and any psychiatric diagnosis and readmission after childbirth.DesignCross-sectional analysis of administrative data from patient discharge records.SettingUrban academic medical center in the northeastern United States.ParticipantsWomen admitted for childbirth (N = 17,905).MethodsDifferences among participants with and without depression and/or anxiety present on admission were compared using t tests and chi-square tests. Risk-adjusted logistic regression models were used to examine the effects of depression and/or anxiety and any psychiatric diagnosis on 7-, 30-, 60-, 90-, and 180-day readmissions after childbirth.ResultsSignificant differences were noted between participants with (n = 1,169) and without (n = 16,736) depression and/or anxiety. Participants with these diagnoses had a higher mean age and a longer mean length of stay during hospitalization for childbirth. A greater proportion of these participants were White, were single, had cesarean births, and were discharged with home health services. The presence of depression and/or anxiety was not significantly associated with readmission. The effect of having any psychiatric diagnosis was significantly associated with a greater risk of readmission at 7 (odds ratio [OR] = 1.51, p = .100), 30 (OR = 1.45, p = .030), 60 (OR = 1.45, p = .026), 90 (OR = 1.56, p = .004), and 180 days (OR =1.74, p < .001) following discharge after childbirth.ConclusionIn this sample, women with a psychiatric diagnosis, but not depression and/or anxiety alone, were at increased risk for readmission after childbirth.     

Outcome of sentinel lymph node biopsy in early-stage squamous cell carcinoma of the oral cavity with methylene blue dye alone: a prospective validation study

Our aim was to evaluate the feasibility and role of sentinel lymph node (SLN) biopsy using methylene blue dye alone in identifying occult lymph node metastases in early oral cancer (cT1, T2, and cN0). The study was done from 2013–15 in 94 patients in a large cancer centre. The blue nodes were dissected and sent for frozen section, routine histopathological examination, and immunohistochemical testing for cytokeratin, and was followed by elective neck dissection in all patients. The identification rate was 93.61%. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy for frozen section and haematoxylin and eosin (H&E) staining were 84.6%, 100%, 100%, 93.9% and 95.5%, respectively. Occult lymph node metastasis was seen in 27.6% cases. Biopsy of SLN with blue dye alone might be used successfully with good sensitivity and negative predictive value in countries with limited resources in the developing world. Immunohistochemistry contributes to it by increasing the sensitivity and NPV, and thereby improves the diagnostic value.     

Premature Ticagrelor Discontinuation in Secondary Prevention of Atherosclerotic CVD: JACC Review Topic of the Week

Ticagrelor is a cornerstone of modern antithrombotic therapy alongside aspirin in patients with acute coronary syndrome and after percutaneous coronary intervention. Adverse effects such as bleeding and dyspnea have been associated with premature ticagrelor discontinuation, which may limit any potential advantage of ticagrelor over clopidogrel. The randomized trials of ticagrelor captured adverse events, offering the opportunity to more precisely quantify these effects across studies. Therefore, a meta-analysis of 4 randomized clinical trials of ticagrelor conducted between January 2007 and June 2017 was performed to quantify the incidence and causes of premature ticagrelor discontinuation. Among 66,870 patients followed for a median 18 months, premature ticagrelor discontinuation was seen in 25%; bleeding was the most common cause of discontinuation followed by dyspnea. Versus the comparators, the relative risk of dyspnea-related discontinuation during follow-up was 6.4-fold higher, the relative risk of bleeding was 3.2-fold higher, and the relative risk of discontinuation due to any adverse event was 59% higher for patients receiving ticagrelor. Understanding these potential barriers to adherence to ticagrelor is crucial for informed patient-physician decision making and can inform future efforts to improve ticagrelor adherence. This review discusses the incidence, causes, and biological mechanisms of ticagrelor-related adverse effects and offers strategies to improve adherence to ticagrelor.
