Molluscum contagiosum (MC),”MC is a skin infection caused by a poxvirus. It is characterized by small, pruritic, skin-colored papules with umbilicated centers. Children are most commonly affected, but adolescents and adults also can develop MC.Transmission occurs through skin-to-skin contact or via contaminated fomites, with subsequent autoinoculation to additional sites. MC is self-limited (resolution within 6-12 months), but treatment with curettage, cryotherapy, or topical agents (eg, podophyllotoxin) may be considered to prevent further spread, reduce symptoms, or improve cosmesis. HIV testing should be considered for patients with MC, especially if they have large (> 10 mm), numerous

Toxic epidermal necrolysis (TEN)?,”TEN is a severe syndrome characterized by the sudden onset of mucocutaneous lesions and systemic signs of toxicity. Typical features include an erythematous eruption that rapidly evolves into exfoliation of the skin. It is most often caused by medications (eg, antibiotics, anticonvulsants, allopurinol). TEN and Stevens, Johnson syndrome (SJS) are similar disorders distinguished by the percentage of involved skin: SSJ involves < 10% of the body surface area, TEN involves > 30

Anemia of chronic disease and iron deficiency?,”Anemia of chronic disease is a disorder of iron utilization that most commonly occurs in the setting of chronic inflammation. It is characterized by normocytic anemia with decreased serum iron, decreased total iron-binding capacity, decreased iron saturation, and normal/elevated serum ferritin. Treating the underlying inflammatory disorder will often improve the anemia. Common inflammatory disorders include infection cancer, autoimmune disorders. Common agents in rheumatoid arthritis treatment include methotrexate, hydroxychloroquine, and tumor necrosis factor inhibitors (eg, infliximab

Cor pulmonale?,”Cor pulmonale refers to impaired function of the RV caused by pulmonary hypertension that occurs due to underlying diseases of the lungs (COPD, interstitial lung disease (ILD)), pulmonary vasculature (idiopathic pulmonary arterial hypertension), or obstructive sleep apnea. By convention, RV dysfunction due to Left heart disease or congenital heart disease is not considered cor pulmonale. Signs of RV failure include:- Elevated jugular venous pressure- RV 3rd heart sound- Tricuspid regurgitation murmur- Hepatomegaly with pulsatile liver- Lower-extremity edema, ascites

Syndrome of inappropriate antidiuretic hormone secretion (SIADH)?,”The syndrome of SIADH is a common complication of lung cancer, particularly small cell lung cancer. The initial treatment of choice is fluid restriction to allow for serum sodium concentration to gradually rise. Severe symptomatic or resistant hyponatremia from SIADH requires administration of hypertonic saline. Demeclocycline

Viral arthritis?,”Viral arthritis presents with the acute onset of polyarticular and symmetric arthritis that resolves within two months. Parvovirus is amongst the most common causes of viral arthritis, and is particularly likely in adults who have frequent contact with children, such as day care workers. Parvovirus in adults most often presents with arthritis/arthralgias involving the MCP, PIP, and wrist joints. The “”slapped cheek”” appearance is unusual in adults, and the presence of systemic symptoms is variable.There is a lack of inflammatory markers
