Tinea Capitis at Ibn Sina Hospital in Rabat, Morocco: Epidemiological and Etiological Study Over 25 Years (From 1997 to 2021).

Introduction/Objective In Morocco, tinea capitis is a common reason for consultation, especially in children. Our study aimed to determine the epidemiology of tinea capitis in the Central Laboratory of Parasitology and Mycology at the Ibn Sina University Hospital Center (UHC) in Rabat. Materials and methods This is a retrospective study conducted over 25 years (from 1997 to 2021). It included 247 patients with lesions suggestive of tinea capitis, who underwent a mycological examination. Results Among 594 requests for the diagnosis of tinea capitis, 247 cases were positive. A clear predominance of children (86.23%; n=213) as compared to adults (13.77%; n=34) was observed. The sex ratio (M/F) was 1.77. Hair parasitism was mainly dominated by the pure endothrix type 54.47% (n=122). The two most frequently isolated species were Trichophyton violaceum (51.24%; n=125) and Microsporum canis (36.06%; n=88). In children, these two species represented 47.42% (n=101) and 41.31% (n=88), respectively. In adults, Trichophyton violaceum was the predominant species, accounting for 77.42% (n=24); in females, it was 76.41% (n=68); and Microsporum canis was predominant in males (50.32%; n=78). Conclusion The epidemiology of this condition is in a constant state of flux, influenced by various lifestyle factors. Our research unveiled a notable upward trend in zoophilic species over the 25-year study period, while conversely, anthropophilic species demonstrated a discernible decline.

A Case of Dual Septic Foci in Both the Joint and Pleural Cavity Caused by Streptococcus agalactiae.

Group B Streptococcus (GBS or Streptococcus agalactiae) is a common component of the human flora. However, infections in adults are infrequent, and occurrences of infectious pleurisy or septic arthritis are exceedingly uncommon. To our knowledge, the concurrent manifestation of both conditions has not been previously documented. We present the case of a 61-year-old man who exhibited an unusual association of infectious pleurisy and septic arthritis in the knee, both attributed to GBS. The patient was admitted to the hospital due to thoracic pain and discomfort in the left knee. Clinical examination revealed a pleural effusion in the left lung and arthritis in the left knee. Synovial and pleural fluid samples were sent to the bacteriology laboratory for cytobacteriological examination, confirming the presence of GBS in both fluids. The patient is diabetic and has a history of undergoing total cystoprostatectomy for a urothelial tumor, with the placement of a mono J catheter. The prevailing hypothesis suggests that the colonization of the mono J catheter, followed by hematogenous dissemination, is the probable source of the infection. This unusual clinical case underscores GBS's ability to induce severe invasive infections in adults, particularly in those with underlying medical conditions.
