Screening of inmates transferred to Spain reveals a Peruvian prison as a reservoir of persistent Mycobacterium tuberculosis MDR strains and mixed infections.

It is relevant to evaluate MDR-tuberculosis in prisons and its impact on the global epidemiology of this disease. However, systematic molecular epidemiology programs in prisons are lacking. A health-screening program performed on arrival for inmates transferred from Peruvian prisons to Spain led to the diagnosis of five MDR-TB cases from one of the biggest prisons in Latin America. They grouped into two MIRU-VNTR-clusters (Callao-1 and Callao-2), suggesting a reservoir of two prevalent MDR strains. A high-rate of overexposure was deduced because one of the five cases was coinfected by a pansusceptible strain. Callao-1 strain was also identified in 2018 in a community case in Spain who had been in the same Peruvian prison in 2002-5. A strain-specific-PCR tailored from WGS data was implemented in Peru, allowing the confirmation that these strains were currently responsible for the majority of the MDR cases in that prison, including a new mixed infection.

An unexpected side-effect of a commonly used drug.

We report a case of a 68 year-old-female patient with clinical features of drug-induced lupus erythematosus after five years of treatment with amiodarone. She presented generalized skin rash, arthralgia on upper and lower extremities, associated with difficulty to walk. Remarkable laboratory results revealed a positive antinuclear antibody test and a skin rash biopsy showing a superficial and deep perivascular infiltrate of lymphocytes, histiocytes, and eosinophils. Once the etiology of the patient's symptoms was identified, the culprit drug was removed and she had a complete remission of all signs and symptoms. Early diagnose should be recognized for prompt intervention and avoid further complications associated with this rare side-effect.

An unusual presentation of herpes simplex in an immunocompromised patient.

Herpes simplex virus (HSV) is a host-adapted human pathogen. HSV-I usually infects non-genital sites at a variety of locations. HSV-2 primarily involves genitalia. Both types can cause genital and orofacial infections, which are clinically indistinguishable. Initial HSV infection is usually asymptomatic or mild and self-limited, but instead of disappearing from the body during convalescence, the virus establishes a latent infection that persists for life. Rarely, there is severe visceral dissemination. This is a case report of an unusual presentation of herpes simplex in an immunocompromised adult patient with generalized skin lesions on the entire body. To our knowledge, this is the first case reported in the literature of a disseminated herpes simplex in a patient with history of non-Hodgkin Lymphoma. Generalized HSV infection in immunodeficient adult patients could be fatal in spite of antiviral therapy. Early recognition of this entity is essential to expedite appropriate treatment and avoid future complications.

Immuno compromised patients: what a challenge!

Mucormycosis is an uncommon but fatal fungal infection of airborne transmission. Its is usually seen in immunocompromised patients including diabetics, malignancies, transplant patients and renal insufficiency. We review the case of an immunocompromised patient unresponsive to broad-spectrum antibiotics and conventional antifungal therapy with lung mucormycosis.

Secondary biliary cirrhosis due to a rare choledochal cyst type II complicated with portal hypertension and pancytopenia in a young female patient.

Choledochal cyst type II, is an extremely rare cause of portal hypertension, severe pancytopenia in an adult patient, and a complication of long-standing disease. We present an uncommon cause of portal hypertension in a young female patient secondary to an obstructive choledochal cyst type II provoking massive splenomegaly and severe pancytopenia. A high level of clinical suspicion is important due to its high mortality rate if it remains undiagnosed. To our knowledge there are few publications describing this rare type of choledochal cyst in a Hispanic adult.
