Clostridium tertium is a bacterium of the Clostridiaceae family which can be found colonizing the gastrointestinal tract. Unlike other members of its family, it does not produce exotoxins. It was described for the first time in 1917 and in 1963 it was established as a pathogen in humans. ⋯ The case of a 48-year-old man with a history of cirrhosis and hepatitis C virus infection is described. He presented an obstructed umbilical hernia that required intestinal resection and anastomosis, with positive blood and abdominal fluid cultures for Clostridium tertium. This case is of clinical importance due to the low prevalence of this germ, the possibility of resistance to usual antibiotic regimens and its sub diagnostic given the morphological and growth similarities with Bacillus or Lactobacillus.

Mixed infection by Mycobacterium tuberculosis (Mtb) consists in the simultaneous coexistence in the same patient of two different strains of Mtb or 2 different variants of the same strain. When one of the variants selects for resistance mutations, it is called monoclonal heteroresistance (HTR); if there are 2 different strains, one sensitive and one resistant (or with different resistance patterns), it is called polyclonal HTR. Three cases of HIV/AIDS patients are presented, all with repeated treatment adherence problems, in whom monoclonal HTR was diagnosed through Mtb complete genomic sequentiation with the coexistence of two variants of the same strain isolated from samples from lung and lymph nodes, with different resistance profiles in each case. It is important to consider the possibility of HTR, especially in patients with multiple previous therapeutic attempts and high bacillary populations, such as in advanced AIDS, since this situation potentially compromises treatment results by coexisting sensitive and resistant variants of a strain (or strains).

Scientific evidence suggests that mother-child joint care strategies would facilitate knowledge of contraceptive methods (MAC) and their access. The objective was to evaluate the effect of the Integrated Mother and Child Care Model on adherence and knowledge of CAM in women during the first postpartum semester. ⋯ Early postpartum intervention with various communication and information strategies can be useful to choose the MAC that is considered most appropriate for each woman and its correct use.

Clear cell renal cell carcinoma (ccRCC) is an uncommon malignant neoplasm that accounts for 3% of all malignant tumors in adults. This tumor exhibits a high tendency to develop synchronous or metachronous metastases in different anatomical sites. Although gallbladder metastasis from ccRCC is extremely rare, sporadic cases have been reported in the medical literature. ⋯ Gallbladder metastasis from ccRCC is extremely rare, but surgeons should consider this possibility in patients with a history of ccRCC. Preoperative differential diagnosis between primary gallbladder carcinoma and ccRCC metastasis can be challenging and is often confirmed through histopathological examination. Complete surgical resection is the best treatment option to achieve disease-free survival.

We present the case of a patient with venous thromboembolic disease and contraindication to anticoagulation, where the incidental finding of a duplication of the inferior vena cava was made. This observation determined the need to implant two embolic protection filters. Although this vascular anomaly is rarely present, it is important to keep this possibility in mind to ensure that proper protection is provided when inferior vena cava filters are implanted.
