Subhepatic appendix: an ectopic topography not to be disregarded: a case report.

J Med Case Rep 2021 May 31;15(1):288. Epub 2021 May 31.

Department of Surgery, Regional Hospital Center of Maradi, Faculty of Health Sciences of the University of Maradi, Maradi, Niger.

Introduction: Subhepatic appendix is most often due to an anomaly of rotation of the primary intestine occurring during embryogenesis. This ectopic topography associated with advanced age can be a serious diagnosis problem at the stage of appendicitis or appendicular peritonitis.

Case Presentation: We report the case of a 60-year-old melanoderm man, with a history of urinary pathology and peptic ulcer, referred from a health district for abdominal pain of the right hypochondrium evolving for about 5 days, secondarily generalized, in whom we suspected peritonitis, the etiology of which remains to be determined. During the surgical intervention, after preoperative resuscitations measures, a phlegmonous perforated appendix was found under the liver. No postoperative complication was noted, and he was discharged home 8 days after his operation.

Conclusion: Subhepatic appendicular peritonitis occurring in an elderly patient poses enormous diagnostic problems. When faced with right upper quadrant pain, considering acute ectopic appendicitis would significantly reduce complications.

[Epidemiological, clinical and evolutionary profile of patients with tuberculosis at the Regional Hospital of Maradi, Republic of the Niger].

Pan Afr Med J 2019 17;33:120. Epub 2019 Jun 17.

Service de Médecine Interne, Hôpital Général de Référence Niamey, Faculté des Sciences de la Santé de l'UAM de Niamey, Niamey, Niger.

Introduction: This study aimed to describe the epidemiological, clinical and evolutionary profile of patients treated for tuberculosis at the Regional Hospital of Maradi.

Methods: We conducted a retrospective, descriptive and analytical study of data from the medical records of patients treated for tuberculosis from 1 January 2015 to 31 December 2017.

Results: A total of 595 patients were followed (406 men, 68.24%, and 189 women, 31.76%) with a prevalence of 27,71%. The average age of patients was 42.3 ranging from 13 months to 85 years; 70.5% of these patients were from urban areas. Merchants represented 36.9% of the cases. Bacterial test was positive in 64.7% of cases. Functional signs included: coughing (99.5%), fever (79.5%), and chest pain. Pulmonary tuberculosis represented 78.7% of cases. Therapy was effective in 81.28% of cases. HIV prevalence was 13.6%, lethality 10.42% (40.4% of patients died from TB/HIV co-infection).

Conclusion: Tuberculosis is a scourge in low-income countries, with 10.42% of deaths. HIV/AIDS infection has negatively contributed to these deaths during the study period. The search for comorbidities in any patient with tuberculosis should be systematic in order to improve their global management.

[Epidemiological and bacteriological features of surgical site infections (ISO) in the Division of Surgery at the Niamey National Hospital (HNN)].

Pan Afr Med J 2018 14;31:33. Epub 2018 Sep 14.

Faculté de Sciences de la Santé, Laboratoire de Bactériologie Virologie, Université Abdou Moumouni de Niamey, Niger.

This study aims to evaluate the epidemiological and bacteriological features of bacterial strains isolated from surgical site infections (ISO) at the Niamey National Hospital. We conducted a retrospective, descriptive study over a period of 24 months. All strains isolated from bacteriological samplings from patients with a surgical site infection have been identified and tested for antibiotic sensitivity according to conventional methods. The bacteriological analysis allowed the isolation of 126 bacterial strains with a predominance of S.aureus (n=39, 31%) followed by Escherichia coli (n=29, 23%) and Pseudomonas aeruginosa (n=12, 9.5%). The strains of Escherichia coli were 100% sensitive to imipenem. They showed marked ampicillin, amoxicillin, clavulanic acid and ticarcillin resistance. They had variable resistance to aminoglycoside antibiotics (62% to gentamycin, and 78% to amikacin) and to fluoroquinolones (nalidixic acid 74%, pefloxacine 33%, ofloxacin 69%, ciprofloxacin 61%). All enterobacterial isolates were sensitive to imipenem. The strains of S.aureus showed resistance to penicillin G (88.6%) and oxacillin (83%). They also showed resistance to vancomycin and teicoplanin (37% and 57% respectively). By contrast, they were sensitive to lincomycin and aminoglycoside antibiotics tested. In the light of these results, we believe that it will be necessary to improve prophylaxis protocol and probabilistic antibiotic therapy in the Surgical Division and to conduct periodic surveillance studies of the ISO.
