Potential of the Bayesian approach in critical care

Claudia Cerantola — 2024-03-21

Bayesian statistics are becoming increasingly popular in medical data analysis and decision-making. Because of the difficulties that RCTs face in critical care, these methods may be particularly useful. We explain the fundamental concepts and examine recent relevant literature in the field.

Loxosceles rufescens: single-institutional epidemiology, diagnosis and treatment

Francesco Coletta — 2024-01-22

Loxosceles rufescens, also known as “violin spider” due to its characteristic appearance, is a medium-sized spider species that can potentially pose a threat to humans. For this study, patients who presented to our hospital’s Poison Control Center between January 1, 2022, and December 31, 2022, and met the following inclusion criteria were included: Suspicion of a violin spider bite, as evaluated by our center. Our protocol involves an initial local treatment, which includes local washing with copious water and disinfection, along with the application of chlorotetracycline hydrochloride. Systemic therapy utilizes Amoxicillin and Clavulanic Acid as the first-line medication. The primary endpoints of this study are the timing and effectiveness of the treatment for cutaneous lesions. Demographic and anamnestic information regarding age, gender, and timelines was summarized using descriptive methods. Our study’s results indicate that erythema and pain are the most frequent symptoms. Loxoscelism is highly concentrated in the Western hemisphere and is considered the only proven arachnological cause of dermo-necrosis. In recent years, there has been an increase in diagnoses.

COVID-19 in pregnant women: description of a possible case of COVID-19-linked HELLP-like syndrome

Fara Russo — 2024-03-25

New evidence suggests that Sars-CoV2 infection during pregnancy may result in complications such as hypertension, nephropathy, thrombocytopenia, and liver damage. A pre-eclampsia-like syndrome has also been proposed in pregnant women with severe SARS-CoV-2 infection, which meets the pre-eclampsia criteria but resolves without delivery, with improvement in respiratory symptoms. 31-year-old, second pregnancy, in Emergency Room for PROM (premature rupture of membranes), has Sars-CoV2 infection and has not been vaccinated. Normal examinations and mild hypertension were present upon admission, but no treatment was administered. Vaginal Leukocytic Delivery 12 hours after admission, newborn Apgar score 9/10, weight 3.250 kg. At 20 hours after delivery, epigastric pain VAS 8-9 for 20 minutes, systolic/diastolic hypertension peak, increase in transaminases, LDH, ALP, Bilirubin, Dimer, platelet and fibrinogen drop. Neurological and respiratory objectivity were negative, and renal indices were within normal limits, so nifedipine 30mgx2/day + methyldopa 500 mgx2/day was started. Abdominal ultrasound revealed a thin perihepatic fluid stratum. A prophilaxis of dexamethasone 12mg twice a day and magnesium sulfate was introduced. At 32 hours after delivery, the laboratory detected an increase in transaminases, LDH, and worsening of thrombocytopenia. The patient is always eupnoic, and the diuresis is adequate. Blood tests improved gradually after 56 hours postpartum. Methyldopa and steroids are escalating. On day 7, discharge with normalized platelet and bilirubin counts and a decreasing trend in transaminases, LDH, and PAL. At the one-week follow-up, liver enzymes and coagulation were completely normal, and blood pressure was well controlled with methyldopa. We conclude that the simultaneous presence of the two diseases could have had a synergistic or opportunistic effect, resulting in severe clinical manifestations via interaction with the Renin-Angiotensin-Aldosterone system.
