Scabies, a skin infestation caused by the microscopic Sarcoptes scabiei mite, can be an uncomfortable and distressing condition. Scabies is primarily caused by the Sarcoptes scabiei mite, a tiny arachnid that burrows into the outer layer of the skin. The infestation occurs through direct, prolonged skin-to-skin contact with an infected person. Contrary to common belief, scabies is not solely associated with poor hygiene, as it can affect individuals of any socio-economic background. The hallmark symptom of scabies is relentless itching, often worsening at night. The itching is the body's allergic reaction to the mites, their eggs and their waste. Small, raised red bumps or pimple-like rashes may appear on the skin, especially in areas with thinner skin, such as between the fingers, wrists, elbows and genital region.

Toxoplasmosis, a parasitic infection caused by the protozoan Toxoplasma gondii, has long been associated with various health concerns. While pregnant women and individuals with compromised immune systems are typically warned about the risks, emerging research has shed light on a less well-known connection – the link between toxoplasmosis and neurological disorders. Toxoplasmosis, caused by the microscopic parasite Toxoplasma gondii, has long been recognized as a potential threat to human health. Beyond its more commonly known risks, recent research has unveiled a fascinating yet concerning aspect – its impact on neurological health. The intricate relationship between Toxoplasma gondii and the human brain, shedding light on the complexities of this "brain invader" and its potential consequences on neurological well-being.

Introduction: Urinary Tract Infections (UTIs) are community-acquired infections frequently encountered in hospitals. The aim of this study was to investigate the diagnostic, therapeutic and evolutionary aspects of urinary tract infections among hospitalized patients in the internal medicine department of DTH-BA.

Methods: This was a descriptive cross-sectional study that systematically included all patients hospitalized for urinary tract infection from January 1^st, 2013 to December 31, 2022. Data on diagnosis, treatment and outcome were collected from patient’s medical records. A team of experts (infectiologist and microbiologist) assessed the quality of antibiotic therapy (justification, relevance of choice, appropriateness). This study was approved by the local biomedical research ethics committee of the University of Parakou. Data were analyzed using SigmaPlot 14.0 software.

Results: A total of 2876 records were analysed, with 183 cases of urinary tract infection, representing a frequency of urinary tract infection in hospitalized patients of 6.36%. The sex ratio was 0.74 and the mean age 40.55 ± 17.53 years. The most common symptoms were fever (134 cases; 73.22%), asthenia (93 cases; 50.82%) and urinary burning (82 cases; 44.81%). The diagnosis was pyelonephritis in 71 (38.80%) patients, acute cystitis in 68 (37.16%) patients and male urinary tract infection in 42 (22.95%) patients. Of 173 (94.54%) Urine Dipsticks (UD) performed, 159 (91.91%) were positive. A Urine Cytobacteriological Examination (UCE) was performed in 37 (20.22%) patients, 32 (86.49%) of them after initiation of antibiotic therapy. A germ was identified in 15 cases (40.54%). Escherichia coli was the most frequent germ (8 cases; 53.33%). In terms of treatment, 182 (99.45%) patients received probabilistic antibiotic therapy, with 133 (73.08%) patients receiving inappropriate management and 14 (93.33%) of the 15 who received an antibiotic susceptibility test being unsuitable. One hundred twenty-four (67.76%) patients were cured, 10 (5.46%) died and 49 (26.78%) were discharged against medical advice.

Conclusion: This study shows that urinary tract infections are managed with probabilistic and inappropriate antibiotics. This result should prompt the development of a protocol for the management of these infections, to ensure the correct use of antibiotics in this department.

In the intricate dance between host and pathogen, the immune system emerges as the unsung hero, orchestrating a complex and dynamic defense against invading microbes. Understanding the pivotal role of immune responses in host-pathogen interactions is not only fascinating from a scientific standpoint but is also imperative for the development of effective strategies in infectious disease management. At the heart of the battle against infectious diseases lies the intricate interplay between the host organism and invading pathogens. Pathogens, ranging from bacteria and viruses to fungi and parasites, constantly evolve to breach the host's defenses. In response, the host deploys a sophisticated immune system, comprising a network of cells, tissues and molecules, all working in harmony to recognize and eliminate the invaders.
