Paraneoplastic edematous dermatomyositis: A rare syndrome observed in a case of small cell lung cancer

Dermatomyositis with subcutaneous edema is a rare process with few reported cases. We report a 63-year-old with lung cancer who presented with an erythematous skin rash and was found to have biopsyproven dermatomyositis. Her course was complicated by generalized edema, myalgias, muscle weakness, dysphagia, and laryngeal edema. The edema was severe and caused respiratory distress requiring intubation. The patient underwent therapy with high-dose glucocorticoids and intravenous immunoglobulin but failed treatment. Altogether, she presented as an extreme case and rare variant of dermatomyositis, known as edematous dermatomyositis. Diagnostic and treatment guidelines do not account for this variant and literature pertaining to edematous dermatomyositis is sparse. Moreover, this disease was a paraneoplastic manifestation of her small cell lung cancer, which is rarely observed. There are no cases reporting edematous dermatomyositis as a paraneoplastic manifestation of small cell lung cancer, and we highlight the high rate of morbidity and mortality in such patients

Near infrared hyperspectral dataset of healthy and infected apple tree leaves images for the early detection of apple scab disease

This dataset presents two series of hyperspectral images of healthy and infected apple tree leaves acquired daily, from two days after inoculation until an advanced stage of infection (11 days after inoculation). The hyperspectral images were calibrated by reflection correction and registered to match the geometry of one reference image. On the last experiment day, scab positions are provided

Efficacy and Safety of Glembatumumab Vedotin in Patients With Advanced or Metastatic Squamous Cell Carcinoma of the Lung (PrECOG 0504)

Glycoprotein NMB is a transmembrane protein linked with poor prognosis and is expressed in most squamous lung cancer. Glembatumumab vedotin is an antibody-drug conjugate targeting glycoprotein NMB, administered intravenously every 3 weeks in this phase 1 study to determine the safety, tolerability, and maximum tolerated dose in patients who had progressed on any number of previous therapies. A total of 13 patients were enrolled; adverse events (of any grade) including dyspnea, neutropenia, respiratory failure, anemia, increased aspartate transaminase/alanine transaminase, diarrhea, and hypophosphatemia were seen in 15% of patients. Grade 5 events included two cases of respiratory failure, either completely or partially attributed to cancer progression. The only other grade 5 event was “disease progression.” The most common adverse events (23%) were decreased appetite, fatigue, rash, and weight loss. The median overall and progression-free survivals were 5.7 months (90% confidence interval: 2.5–16.8) and 2.5 months (90% confidence interval: 1.6–5.8) respectively. Glembatumumab vedotin exhibited no serious or unexpected toxicity in this heavily pretreated population, except those caused by disease progression. Modest anticancer activity was observed with a recommendation for a phase 2 dose of 1.9 mg/kg. This portion of the study was not undertaken owing to the company’s decision to discontinue drug development
