It is a rare clinical entity especially in subsahara Africa. Case presentation: We report the case of a 45 years old female patient who consulted for a one month history of generalised muscle cramps, weakness and numbness of all four limbs. Physical examination was relevant for a poor gait, poor coordination of both upper and lower limbs, a positive Romberg sign, normal muscle tone in all four limbs, reduced pallesthesia and deep tendon reflexes, abolished plantar reflexes. Paraclinical investigations revealed macrocytosis without anemia, a low cyanocobalamin (vitamin B<sub>12</sub>) level with a normal folic acid level, an atrophic corporeofundic mucosa which upon pathological analysis revealed a chronic atrophic gastritis with no Helicobacter pylori infection. Anti-intrinsic factor antibodies were positive while anti parietal cells antibodies were negative. The diagnosis of Biermer disease was considered and the patient did well on vitamin B<sub>12</sub> supplementation. Conclusion: Though a rare disease, Biermer disease should be considered in a patient who consults for polyneuropathy even in the absence of anemia.展开更多

Methods: We carried out a cross-sectional study from January 2 to July 3 (2016), in Department of Gastroenterology at University Hospitals of Cocody (CHUC) and Yopougon (CHUY). All the black African patients included were more than 15 years old and their liver elasticity score (LES) was carried out at Yopougon University Hospital. Hepatitis B related cirrhosis was defined by LES ≥ 11 kPa (FibroScan? (Echosens, France)) with positive HBs antigen (HBsAg) and anti HBc antibody. All the patients with hepatitis B related cirrhosis performed a gastroscopy at Cocody University Hospital and esophageal varices were ranked according to société fran?aise d’endoscopie digestive (SFED) classification. Data analysis was performed by SPSS model 20.0 statistics software (SPSS Inc., Chicago, IL, United States). Diagnostic performance of LES 150,000/mmm3 (Baveno VI criteria) for the diagnosis of large EV by gastroscopy was studied (area under the ROC curve, specificity (Sp), sensitivity (Se), positive predictive value (PPV) and negative predictive value (NPV). Results: During the study period, 720 patients achieved liver FibroScan? at CHUY. Of these, 60 respondents to our inclusion criteria were prospectively included in our study. Twelve (20%) of these 60 patients met the Baveno VI criteria. EV were present in 40% of cases (n = 24) with 6.7% (n = 4), 15% (n = 9) and 18.3% (n = 11) of grade 1, 2 and 3, respectively. (66.7% (n = 40) without EV or with small EV) and 33.3% (n = 20) with large EV. The Baveno VI criteria had a Se, Sp, PPV and NPV of 100%, 41.6%, 30% and 100% respectively for the diagnosis of large EV. The area under the ROC curve of a platelet count greater than 150,000/mm3, a liver elasticity score of less than 20 kPa and combination of both were respectively 0.763 [0.645 - 0.880;P = 0.272];0.588 [0.436 - 0.739;P = 0.01] and 0.650 [0.513 - 0.787 P = 0.005]. Conclusion: The combination of liver elasticity score 150,000/mm3, allowed the exclusion of large esophageal varices at gastroscopy with a 100 % NPV in Black African patients with compensated hepatitis B related cirrhosis.展开更多

In the clinical examination, we had found anemia syndrome, nodules under cutaneous about 2 cm in diameter at the level of the thorax, of the belly, the members and of the lower lip partners in a painless left adenopathy axillary about 3 cm in diameter and an absence of méléna in the rectal touch. The gastroscopy had highlighted polypoides ulcéro-bourgeonnantes hurts with a blackish pigmentation by places at the level of the bulb and of the second duodenum. In the histology of biopsie fragments, we noted a fuso-cellular proliferation and epithelioid with deposits of melanin.
