We report the first case of a post-acupuncture soft tissue infection due to Mycobacterium fortuitum. Two months after finishing an acupuncture treatment session, an immunocompetent 23-year-old woman developed cellulitis at the side of the needle insertions and the acidfast bacillus was isolated from a closed abscess. The patient was successfully treated with a proper drug combination. We review the literature concerning the infection source and the risks for skin and soft tissue infection due to mycobacteria after acupuncture. The infection source in most cases is unknown but is probably associated with the inadequate sterilization of the needles or the puncture site. We show that these infections are not rare but difficult to diagnose. To avoid delays in the definitive diagnosis, infection with mycobacteria should be considered for skin and soft tissue infections, in particular late-onset infections, which are negative for routine bacterial cultures and without a clinical response to antibiotics used for acute pyogenic infections. Bacterial cultures from this lesion should be maintained for at least six weeks before discharged as negative.

Background Malaria remains a significant public health problem worldwide. Simultaneous infections with other pathogens complicate its diagnosis and can also change the clinical course of the disease. The similarities in the clinical presentation of malaria and other infections and the superimposed endemicity result in underdiagnosis of coinfections and increase mortality. No studies have focused on the presence of coinfections in patients with malaria in Venezuela. Methods Between June and November 2018, we conducted a cross-sectional study in patients with malaria who presented to any of the three reference medical centers in Ciudad Bolívar, Venezuela. A clinical and laboratory evaluation searching for coinfections with Dengue (DENV), Chikungunya (CHIKV), Viral Hepatitis (VH) (A, B, and C), and Leptospirosis (LEP) was performed using ELISA to test each patient. Results We studied a total of 161 patients of whom 106 (65.8%) presented P. vivax infection, 43 (26.7%) P. falciparum, and 12 (7.5%) had mixed malaria infections. Coinfections were found in 55/161 (34.2%) patients and were more frequent in patients with P. falciparum (48.8%) than in those with P. vivax (29.2%), or mixed infection (25%) [OR = 2.43; 95% CI = 1.39–4.25; p = 0.018]. The most prevalent coinfection was with DENV (14.9%), followed by HAV (11.8%), HBV (6.2%), CHIKV (5.5%), and LEP (3.7%). Coinfection with HCV was absent. Complicated malaria was significantly more frequent in coinfected individuals (56.4%) than those without coinfection (35.8%) [OR: 2.31; 95% CI = 1.18–4.92; p = 0.013]. Conclusion We found a high prevalence of coinfections in patients with malaria in this region, which was related to a worse outcome. Further prospective studies with samples at different points of infection and the use of molecular tools are needed.
