Pediatric osteomyelitis is a serious infection in children leading to significant morbidity and hospitalization[1].Infections most commonly occur in the long bones,and 52%-70% are caused by staphylococcus aureus(***)[2-4].Methicillin-resistant staphylococcus aureus(MRsA)has been associated with higher rates of complications for children with acute osteomyelitis.

In recent years, social research surrounding the consequences of infertility has increasingly focused on the male perspective;however, a gap exists in the understanding of men’s experiences of male infertility treatment. This review aims to synthesize theexisting evidence concerning the psychological, social, and sexual burden of male infertility treatment on men, as well as patientneeds during clinical care. A systematic search identified 12 studies that are diverse in design, setting, and methods. Psychologicalevaluations have found that urological surgery may have a lasting impact on infertility-specific stress, and treatment failure canlead to feelings of depression, grief, and inadequacy. Men tended to have an avoidant coping mechanism throughout fertilitytreatment, and their self-esteem, relationship quality, and sexual functions can be tied to outcomes of treatment. Partner bonds canbe strengthened by mutual support and enhanced communication;couple separation, however, has been noted as a predominantreason for discontinuing male infertility treatment and may be associated with difficult circumstances surrounding severe maleinfertility. surgical treatments can affect the sexual functioning of infertile men;however, the impact of testicular sperm extractionoutcomes appears to be psychologically driven whereas the improvements after microsurgical varicocelectomy are only evident inhypogonadal men. Clinically, there is a need for better inclusion, communication, education, and resource provision, to addressreported issues of marginalization and uncertainty in men. Routine psychosocial screening in cases of severe male infertility andfollow-up in cases of surgical treatment failure are likely beneficial.

Background: Tuberculosis (TB) is one of the top lethal infectious diseases worldwide. In recent years, interferon-γ (INF-γ) release assays (IGRAs) have been established as routine tests for diagnosing TB infection. However, produced INF-γ assessment cannot permit to distinguish active ATB from latent TB infection (LTBI), especially in TB epidemic areas. In addition to IFN-γ, interleukin-2 (IL-2), secreted by activated T cells, is involved in immune response against Mycobacterium tuberculosis. This could be involved in the follow up of treatment response. The aim of our study was to determine IFN-γ and IL2 cytokines profiles of patients under antituberculosis treatment. Materials and Methods: A six months’ cross-sectional study was conducted at the Jamot Hospital of Yaoundé, from May to August 2021. sociodemographic and clinical data as well as 5 mL of blood were collected from each participant. INF-γ and IL-2 were determined using indirect Enzyme linked Immuno-sorbent Assay (ELIsA) according to the manufacturer’s recommendations and spectrum exam in combination with radiography and GeneXpert were used as standard. P-values Results: The results showed that men were more infected 14/61 (31.8%) with a high presence in active and resistant TB groups. The mean age was 41.3 ± 13.1 years with a 95% CI = [38.2 - 44.7], the age group with the highest infection rate was ranged between 31 and 40 years. The IL-2 and INF-γ means were respectively 327.6 ± 160.6 pg/mL and 26.6 ± 13.0 pg/mL in ATB patients, 251.1 ± 30.9 pg/mL and 21.4 ± 9.2 pg/mL in patients with resistant tuberculosis, while it was 149.3 ± 93.3 pg/mL and 17.9 ± 9.4 pg/mL in cured patients, 15.1 ± 8.4 pg/mL and 5.3 ± 2.6 pg/mL in participants presumed healthy (p γ and IL-2rates were observed between the different groups. Conclusion: Monitoring the serum levels of INF-γ and IL-2 would be useful for the follow-up of anti-tuberculosis patients, particularly in the both cytokines association case.
