Recognition of the agents most commonly implicated in causing methemoglobinemia can provide context for making therapeutic decisions and inform the diagnostic process. We evaluated the etiologic agents most commonly implicated in clinically significant methemoglobinemia using data from the National Poison Data System (NPDS).
What are the most frequent etiologic agents associated with clinically significant methemoglobinemia.
This was a retrospective cross-sectional chart review using electronic data from the NPDS. The NPDS database was queried to identify cases from July 1, 2007, to June 30, 2017, that were coded as methylene blue treatment recommended and/or performed. Cases were excluded if the substance(s) have never been known to cause methemoglobin or the substances suggested methylene blue was used adjunctively for refractory shock (eg, calcium channel or beta blocker). Multiple substance exposures were reviewed and substances not known to cause methemoglobinemia were excluded.
The primary end point was to summarize the most frequent etiologic agents associated with the administration of methylene blue for clinically significant methemoglobinemia.
There were 2563 substances reported in 1209 cases. After excluding coingestants and cases not associated with methemoglobinemia, there were 1236 substances. The top 4 substance categories were benzocaine, phenazopyridine, dapsone, and nitrates/nitrites.
This study reveals the relative contribution of various drugs and chemicals associated with methylene blue administration. Over two-thirds of all cases were associated with benzocaine, phenazopyridine, dapsone, and nitrates/nitrites.

Studies involving the glucagon-like peptide-1 receptor agonist (GLP-1 RA) liraglutide have shown reductions in hemoglobin A1c (HbA1c), weight, and insulin requirements in patients with type 2 diabetes mellitus (DM2) requiring high-dose insulin therapy. The effect of the class of GLP-1 RAs on these parameters is unknown.
A retrospective cohort analysis was conducted in patients with DM2 where a GLP-1 RA was added to high-dose insulin therapy. The primary composite outcome was the change from baseline to 9 months in HbA1c, weight, and insulin dose.
GLP-1 RA therapy was associated with a significant reduction in HbA1c from baseline (-0.9%; P = 0.022). Weight and insulin dose were not significantly reduced from baseline. There was a moderate effect of individual agents on these outcomes, but no significant reductions were seen due to the small sample size.
Generalizability of these findings may be limited by the characteristics and size of the study population.
The effect of GLP-1 RA therapy on HbA1c may be attributed to the medication class. The effect of individual agents on weight and insulin requirements needs further investigation.

Israel has a regulated system with clearly defined indications for treatment with medical cannabis.
The main question was whether family physicians in southern Israel face barriers/knowledge gaps in prescribing cannabis for medical indications. The secondary question was whether there was a difference between residents and specialists in family medicine.
A questionnaire-based cross-sectional study.
Attitudes of the participating physicians on the use of medical cannabis; comparison of attitudes of specialists in family medicine and residents on the use of medical cannabis.
One hundred and fifty-two family physicians participated in the study including 48 residents. More than 78% supported the use of medical cannabis and about 63% supported it's legalization. About 84% of the physicians believed that medical cannabis helped cancer patients and 82% believed it helped in the chronic pain. Only 28.3% believed that family physicians should recommend the use of medical cannabis. Autophagy inhibitor The physicians were well ais encouraging that residents are motivated to undergo training to prescribe medical cannabis. There remain medical indications and adverse effects that family physicians are less aware of. Further studies should focus on effective ways to improve the level of physicians' knowledge on the issue.
Blue rubber bleb nevus syndrome (BRBNS) is a rare systemic venous malformation (VM) disease. The characteristic gastrointestinal (GI) bleeding from multiple VM lesions causes severe chronic anemia which renders most patients depend on lifelong blood transfusion and frequent endoscopic treatment with dismayed outcomes. Although recent case reports suggest that oral sirolimus (rapamycin) is effective, a comprehensive evaluation of its efficacy and safety is in need.
A prospective study was conducted for both pediatric and adult BRBNS patients with administration of sirolimus at the dose of 1.0 mg/m2 to maintain a trough concentration of 3-10 ng/mL. Laboratory tests including complete blood count, biochemical profile, D-dimer, and whole-body magnetic resonance imaging were performed at baseline and 3, 6, and 12 months after treatment. Clinical indicators such as hemoglobin level, lesion size, and transfusion need were evaluated. Adverse effects were recorded regularly.
A total of 11 patients (4 males and 7alleviates GI bleeding, and eliminates transfusion dependence of patients with BRBNS. The drug-related adverse effects are mild and mostly self-limited. These findings support sirolimus as a first-line treatment for GI and cutaneous VMs of BRBNS (see Visual abstract, Supplementary Digital Content, http//links.lww.com/AJG/B819).
The 2019 novel coronavirus disease (COVID-19) has spread worldwide, infiltrating, infecting, and devastating communities in all locations of varying demographics. An overwhelming majority of published literature on the pathologic findings associated with COVID-19 is either from living clinical cohorts or from autopsy findings of those who died in a medical care setting, which can confound pure disease pathology. A relatively low initial infection rate paired with a high biosafety level enabled the New Mexico Office of the Medical Investigator to conduct full autopsy examinations on suspected COVID-19-related deaths. Full autopsy examination on the first 20 severe acute respiratory syndrome coronavirus 2-positive decedents revealed that some extent of diffuse alveolar damage in every death due to COVID-19 played some role. The average decedent was middle-aged, male, American Indian, and overweight with comorbidities that included diabetes, ethanolism, and atherosclerotic and/or hypertensive cardiovascular disease.
