Case Reports Case 1 A 39 year-old-male, on the 2nd month multidrug therapy-MB (MDT-MB) treatment presented with painful punched-out ulcers over the back, arms, and legs of 1 week duration. [ijmyco.org]
Eighteen patients (66.6%) presented with typical vesico-bullous target lesions, whereas the other diagnosed patients presented with various skin erythematous patches, plaques, papules and ulcers (Fig. 1A, C ). [scielo.br]
History and Physical The presentation of nocardiosis is variable and depends greatly on the organ systems involved in the infection. Primary Cutaneous Nocardiosis This form of nocardiosis presents in the form of skin and skin structure infections. [statpearls.com]

- Microcytic Anemia
MICRO EXAM-MUSCULOSK NEC [ ] (UMLS (ICD9CM) C0177963) =Laboratory Procedure 93. microcytic/hypochromic anemia [anemia featuring pale erythrocytes smaller than 6 microns in diameter; typically due to iron deficiency or abnormalities in hememetabolism. [medindex.am]
Microbiology
- Gram-Positive Bacteria
Classification of Gardnerella is controversial, and MeSH catalogues it as both a Gram-positive and Gram-negative organism.[15] Actinomycetota, especially Streptomyces spp., are recognized as the producers of many bioactive metabolites that are useful [en.wikipedia.org]

Treatment
Kong et al found that treatment changed the bacterial skin diversity in AD and suggested that treatments diversify skin bacteria preceding improvements in disease activity. [dovepress.com]
Prophylaxis (treatment of latent tuberculosis infection) Secondary prophylaxis following successful treatment of disease is unnecessary, however, re-infection can occur. [hivmanagement.ashm.org.au]
Treatment of precipitating infections Herpes simplex virus: Antiviral agents may be indicated in HSV infection and a 5-day course of acyclovir 200 mg five times daily at the first sign of lesions, or 400 mg four times daily, or continuous treatment using [ncbi.nlm.nih.gov]
The participants received no further medication and none terminated treatment. [scielo.br]
Because of the potential resistance to sulfonamides, it is important to start treatment based on drug susceptibility results. Outcomes There are only small cases series on outcomes of Nocardia treatment. [statpearls.com]
Prognosis
The prognosis of nocardiosis is variable. [statpearls.com]
Nonetheless, for a very small number of people, it can take up to three months for the test to give an accurate result Management The life expectancy for patients with HIV has increased dramatically The best prognosis is in those diagnosed and treated [pcds.org.uk]
Prognosis The prognosis of untreated MAC infection therapy is poor. [hivmanagement.ashm.org.au]
Etiology
McKee's Pathology of the Skin is the most complete, in-depth resource on dermatopathology, covering etiology, pathogenesis, disease mechanisms, and recent genetic, molecular, and basic science data. Drs. J. [books.google.es]
Etiology and Pathophysiology The exact pathophysiology of EM is incompletely understood but appears to be the result of a TH1-mediated immune response to an inciting event such as infection or drug exposure. [unboundmedicine.com]
Many suspected etiologic factors have been reported to cause erythema multiforme (EM). [emedicine.medscape.com]
However, there is little evidence to demonstrate the etiologic role of MTB in the pathogenesis of EN and NV. [journals.plos.org]
Skin biopsy is not necessary when the clinical picture is clear, as biopsy findings in EM are nonspecific. 2 Management of EM involves determining the etiology, when possible, and treating the suspected infection or discontinuing the causal drug. [thepermanentejournal.org]
Epidemiology
Epidemiology Incidence Annual U.S. incidence is estimated at 1 ). Prevalence Peak incidence in 20s to 40s; rare 50 years of age Slight male predominance is observed. [unboundmedicine.com]
Dissemination throughout the remainder of the body may occur from either of these initial inoculations. [2] Epidemiology Nocardiosis has an infection incidence rate of approximately 500 to 1000 cases per year in the United States. [statpearls.com]

Prevention
All patients with evidence of latent TB infection should receive treatment for the prevention of active disease (often called prophylaxis). [hivmanagement.ashm.org.au]
Acyclovir or valacyclovir may help prevent herpes-related recurrent EM. [unboundmedicine.com]
Herpes simplex virus suppression and even prophylaxis (with acyclovir ) has been shown to prevent recurrent erythema multiforme eruption. [ citation needed ] Treatment [ edit ] Erythema multiforme is frequently self-limiting and requires no treatment. [en.wikipedia.org]
