Mastitis represents a spectrum of inflammatory conditions. Lactational mastitis is the most common, with an approximate incidence of 10% in the United States, and it usually occurs in the first 3 months postpartum. Diagnosis is made clinically based on the presence of symptoms such as fever, malaise, focal breast tenderness, and overlying skin erythema or hyperpigmentation without the need for laboratory tests or imaging. ⋯ Use of probiotics for treatment or prevention is not supported by good evidence. Factors that increase the risk of mastitis include overstimulation of milk production and tissue trauma from aggressive breast massage; therefore, frequent overfeeding, excessive pumping to empty the breast, heat application, and breast massage are no longer recommended because they may worsen the condition. The best prevention is a proper lactation technique, including a good infant latch, and encouraging physiologic breastfeeding rather than pumping, if possible.

Obesity in the United States is increasing, with the most recent national data indicating a prevalence of 41.9%. Obesity is generally considered a body mass index (BMI) of 30 kg per m2 or greater; however, increased waist circumference (female: 35 inches or greater; male: 40 inches or greater) may be a more accurate indicator of obesity, particularly in older adults. For patients who are overweight or obese, the history should include whether patients are taking medications that can increase weight and identifying comorbid conditions contributing to or resulting from obesity. ⋯ Pharmacotherapy with anti-obesity medications such as glucagon-like peptide-1 receptor agonists, sympathomimetics, and others should be considered for any patient with a BMI of 30 kg per m2 or greater and for any patients who are overweight (i.e., BMI of 27 kg per m2 or greater) with metabolic comorbidities. Referral for bariatric surgery should be considered for patients who meet the criteria. Successful management requires individualized support systems with periodic follow-ups through each phase of treatment.

Conjunctivitis caused by viruses, bacteria, or allergies is one of the most common eye conditions in primary care. There is no single sign or symptom that accurately differentiates viral from bacterial conjunctivitis. A comprehensive history and physical examination can guide diagnosis. ⋯ Bacterial conjunctivitis is more common in children and typically presents as mucopurulent discharge with the eyelids matted shut. Delayed antibiotic prescribing has been found to have similar symptom control as immediate prescribing. Ophthalmology referral is indicated for conjunctivitis in a neonate or patients with severe pain, decreased vision, recent ocular surgery, vesicular rash on the eyelids or nose, history of rheumatologic disease, or immunocompromised state.
