Shigellosis is a form of bacterial diarrhea caused by gram-negative bacteria Shigella species. It is common in developing countries and results from contaminated food, poor sanitation conditions, or direct person to person contact. Shigella can cause infection in all age groups. High-risk group include very young, elderly, and immunocompromised person. Shigella species is relatively resistant to acid in the stomach, and few organisms are required to cause the disease. Once ingested, it multiplies in the small intestine and enters the colon. In the colon, it produces shigella enterotoxins and serotype toxin 1, resulting in watery or bloody diarrhea. Clinical presentation of shigellosis may vary over a wide spectrum from mild diarrhea to severe dysentery. We report the case of 7 years old previously healthy boy, who presented to our hospital with abdominal pain, vomiting, and constipation. On examination, we noticed abdominal tenderness with guarding at the right lower quadrant. With the diagnosis of acute appendicitis, open appendectomy was performed. Exploration of the abdominal cavity revealed perforated appendicitis and generalized peritonitis. Shigella sonnei was isolated from the peritoneal fluid culture. The patient completely recovered without any complications. Surgical complications, including appendicitis, could have developed during shigellosis. There are few reported cases of perforated appendicitis associated with Shigella. Prompt surgical intervention can be beneficial to prevent morbidity and mortality if it is performed early in the course of the disease.
Background: Cryptococcal infection is opportunistic and causes high morbidity and mortality among severely immunocompromised patients, specially those living with HIV/AIDS (PLHIV). Cryptococcus neoformans is the most frequently identified species, incriminated in 90% of cryptococcal meningitis (CM). Methods: This is a descriptive retrospective study over a 2-years period (2021 - 2022) involving 12 PLHIV in whom we have isolated Cryptococcus neoformans from cerebrospinal fluid (CSF), blood culture, respiratory or skin specimen. All patients received antifungal therapy, associated to therapeutic lumbar punctures for those who presented with increased intracranial pressure. The clinical examination findings, laboratory data and evolution under treatment of these patients were reviewed. Results: The twelve patients were all HIV-infected adults, with median age of 41.25 ± 12.22 years and male predominance with a sex ratio of 1:2. All patients had low CD4 T-cell counts at diagnosis (<100 cells/µl). Neurological involvement existed in all patients of this cohort : Isolated CM was diagnosed in three cases (25%). Nine patients (75%) had disseminated cryptococcosis: Central nervous system (CNS) with positive hemoculture in six cases, CNS and pulmonary involvement with positive hemoculture in two cases, CNS and cutaneous involvement with positive hemoculture in one case. Cryptococcus neoformans was identified in all cases. Of the twelve patients, seven (58%) survived with good response to the treatment. Lethality rate was 42%. Conclusion: This study demonstrates cryptococcal disease is a high mortality infection in PLHIV.Priority should be given to access to rapid diagnostic CrAgtests to accessibility to liposomal amphotericin B. This could improve the clinical outcome of the patients in our moroccan context.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
