Available data on the use of formaldehyde (formalin solution) for hemorrhagic cystitis (HC) is primarily limited to small retrospective studies and older case reports, and formall guidance on its use is scarce. One guideline by the Canadian Urological Association, as well as several clinical practice reviews, consistently describe intravesical formalin as a last-line intervention for refractory HC, emphasizing that it is typically considered only after other medical and procedural therapies h...

A 2019 Canadian Urological Association best practice report on the management of hemorrhagic cystitis in the pediatric population states that clinicians can consider sclerotherapy with formalin in severe, refractory cases, but as a last resort prior to irreversible surgical options (Level 3 evidence, Grade D recommendation). Given that instillation is painful, general anesthesia is required and it is recommended that all patients undergo evaluation for vesicoureteral reflux (VUR) beforehand to prevent upper-tract injury. If VUR is present, ureteral orifices may be temporarily occluded during treatment with Fogarty catheters. Reports using 4% formalin have been effective with some children improving after a single treatment while lower concentrations (1-2%) have been effective but required multiple instillations. The guideline emphasizes that due to potential long-term bladder compromise (e.g., bladder scarring), formalin should be typically avoided or use as a last resort, especiall...

Guidance from ACOG recommends considering IV iron in postpartum women who cannot tolerate or do not respond to oral iron or in women who had severe iron deficiency later in pregnancy. No dosing recommendations were made, but studies used ferrous sucrose doses up to 600 mg, ferric carboxymaltose doses up or 3,000 mg, or iron dextran 1,000 mg with various numbers of infusions across different time periods. Among available products, iron sucrose has been most commonly studied in postpartum anemi...

Per 2021 American College of Obstetricians and Gynecologists (ACOG) guidelines, both oral and parenteral iron are effective for repletion of iron stores in postpartum women. Meta-analyses have found intravenous (IV) iron resulted in higher hemoglobin concentrations 6 weeks postpartum compared to oral iron replacement (mean difference 0.9 g/dL; 95% CI 0.4 to 1.3 g/dL; p= 0.0003). Additionally, there are fewer gastrointestinal adverse effects associated with IV iron compared with oral iron. Based on the available evidence, ACOG recommends considering parenteral iron for pregnant (after the first trimester) or postpartum women who cannot tolerate or do not respond to oral iron. Parenteral iron can also be considered for women with severe iron deficiency later in pregnancy. [1] A 2024 review highlights the significant burden of PPA, primarily caused by iron deficiency (ID) and exacerbated by peripartum blood loss. The review elucidates the effectiveness of timely detection and iron s...

Available literature describing nicotine replacement therapy (NRT) dosing strategies for individuals using high-nicotine e-cigarettes or vaping systems is limited, and most recommendations are extrapolated from traditional smoking cessation guidance. In general, combination NRT is commonly suggested, consisting of a transdermal nicotine patch to provide baseline nicotine exposure with a rapid-acting formulation (eg, gum, lozenge, oral spray, or inhaler) used for breakthrough cravings and with...

A 2025 position statement from the Thoracic Society of Australia and New Zealand on the management of electronic cigarette use recommends nicotine replacement therapy (NRT) strategies that substitute the high-peak nicotine delivery of vaping with slower, sustained nicotine exposure to mitigate withdrawal symptoms. Combination NRT is emphasized as a preferred approach, typically consisting of a transdermal nicotine patch combined with a faster-acting buccal formulation such as nicotine gum, lozenge, or oral spray. The patch provides continuous baseline nicotine delivery, while rapid-acting formulations can be used as needed to control cravings and withdrawal. Suggested dosing examples include a 21 mg transdermal patch for adults (or 14 mg for individuals <45 kg) together with rapid-acting NRT used liberally for breakthrough cravings. Treatment selection and dosing should be individualized according to the patient’s level of nicotine dependence, with clinicians encouraged to assess de...

Evidence specific to hospitalized patients with uncomplicated cystitis is limited, and most data evaluating antibiotic duration derives from outpatient studies. Societal guidelines recommend short-course therapy for uncomplicated cystitis and notes that although most patients are treated as outpatients, these best practice statements may also apply to patients presenting in the inpatient setting. Recommended regimens include trimethoprim–sulfamethoxazole for 3 days, nitrofurantoin for 5 days,...

According to the 2021 American College of Physicians and Infectious Diseases Society of America/European Society for Microbiology and Infectious Diseases guidelines, short-course antibiotic therapy is recommended for uncomplicated cystitis, with the duration determined by the antimicrobial agent used. The American College of Physicians guidance notes that although most patients with these infections are managed in the outpatient setting, the best practice advice statements also apply to patients who present in the inpatient setting. Recommended regimens include trimethoprim–sulfamethoxazole for 3 days, nitrofurantoin for 5 days, or fosfomycin as a single dose. These recommendations are based on clinical trial data demonstrating that short courses provide similar clinical cure rates to longer regimens while reducing unnecessary antibiotic exposure. Fluoroquinolones are also highly effective in 3-day regimens but are generally reserved as alternative agents because of adverse effects ...

Due to the absence of supportive data and heterogeneity of specific probiotic products available, none are particularly recommended for treating or preventing C. difficile. The 2021 American College of Gastroenterology (ACG) guidelines recommend against probiotics for the prevention of Clostridioides difficile infection (CDI) in patients being treated with antibiotics (primary prevention) and for the prevention of CDI recurrence (secondary prevention). While the 2021 Infectious Diseases Socie...

In the setting of Clostridioides difficile infection (CDI), the 2021 American College of Gastroenterology (ACG) guidelines recommend against probiotics for the prevention of CDI in patients being treated with antibiotics (primary prevention) and for the prevention of CDI recurrence (secondary prevention). Since probiotics are marketed as dietary supplements without strict oversight by the U.S. Food and Drug Administration required for drugs, the evidence for the use of probiotics is generally limited. Hence, manufacturers have little incentive to conduct clinical trials to support specific indications. Additionally, data based on case reports revealed several risks associated with the use of probiotics including bloodstream infections in critically ill patients. Microbiome analyses have also observed probiotics to impede normal recolonization of the colon after antibiotic courses. Evidence to support probiotics for CDI comes primarily from meta-analyses that pooled data from small t...

So they’re basically connecting academic researchers with front line providers and then automating everything. It’s simply brilliant.


     

The clinical pharmacist was our secret weapon anyway. (Smiles wryly) This pharmacist AI seems superhuman. I’m just blown away, honestly. (Looks at camera somberly.)


     

It’s an ENTIRE DI DEPARTMENT, that lives in Epic. Give me a second. I’m just having a hard time wrapping my head around that.
