Risk fаctоrs fоr infectiоus endocаrditis include rheumаtic heart disease, congenital or acquired valvular disease, and intravenous drug use. Infectious endocarditis is classified as acute or subacute depending upon the time course and presentation. Acute endocarditis more often affects normal valves in younger patients. Septic and significant illness are common on presentation. Subacute endocarditis has a predilection for abnormal valves and more frequently occurs in older patients. These patients are typically less ill on presentation with intermittent fevers and constitutional symptoms. Left-sided endocarditis involves either the aortic or mitral valve. It is more common than right-sided endocarditis. Organisms often implicated in left-sided endocarditis include Streptococcus viridans, Staphylococcus aureus, and those in the Enterococcus family. Complications include systemic infarcts from septic emboli. Presenting symptoms often include fever, cough, hemoptysis, chest pain, and dyspnea. Dermatologic and ocular manifestations of endocarditis are important indicators of the diagnosis. Roth spots are retinal hemorrhages with central clearing seen on funduscopic examination. Osler nodes are painful nodules on fingers and toes. Janeway lesions are painless erythematous plaques on the palms and soles. Splinter hemorrhages occur beneath the nails due to septic emboli. Diagnosis is made by having either both major criteria, 1 major and 3 minor criteria, or 5 minor criteria. Major criteria include 2 positive blood cultures with at least 3 sets sent one hour apart of organisms common to infectious endocarditis or abnormal echocardiography with either visible vegetation, new valvular regurgitation, prosthetic valve dehiscence, or myocardial abscess. Echocardiography is the hallmark of imaging for endocarditis and is preferably done via the transesophageal route. Minor criteria include predisposing risk factors or IV drug use, fever, vascular events such as septic emboli and Janeway lesions, immunologic events such as Osler nodes or Roth spots, echocardiographic findings consistent with endocarditis not meeting major criteria, and positive blood cultures not meeting major criteria. Management includes antibiotics for the suspected organism based on the clinical situation. In an IV drug user, coverage should include methicillin-resistant Staphylococcus aureus and Pseudomonas aeruginosa in addition to the typically implicated organisms. The most appropriate antibiotics for this patient would include ceftriaxone and vancomycin. The timeline given (5 weeks) in the question suggests subacute endocarditis which means Strep viridans would be the most common causative agent.
Serum ferritin tests mаy reveаl аn underlying irоn deficiency in patients with symptоms suggestive оf telogen effluvium. Telogen effluvium should be considered inpatients complaining of an increased number of hairs being lost compared to their normal shedding volume. Activities like shampooing and combing can result in over150 hairs lost daily, compared to a normal loss of 70-100 hairs daily. The hair loss in telogen effluvium is due to an abnormally high quantity of hairs shifting prematurely to the telogen, or “resting,” phase in the hair growth cycle. This inappropriate shift may be idiopathic, or may be preceded by two to four months by a physiologically or psychologically aggravating factor. Some known aggravators are pregnancy, crash dieting, illnesses causing high fever, use of new hormonal contraceptives, or stress following a surgery or major illness. Medications are often contributing factors; some common ones are ACE-inhibitors, lithium, antithyroid agents, and certain anticoagulants. On a physical exam, no discrete bald patches or distinct hair loss pattern is noted. However, a hair-pull test will dislodge greater than 10 percent of a clump of 40-60 hairs when moderate traction is applied. A large number of hairs will have a characteristic white bulb at the tips. Additionally, studies have shown an association with iron deficiency anemia, noting that hair counts were found to be directly related to serum iron levels. Acute telogen effluvium should resolve with no complications in most patients. Emotional support as the condition resolves may be necessary and helpful.
