Introduction: Aplasia cutis congenita is a rare congenital dermatosis of which type VI represents the Bart’s syndrome. The aim of this case is to describe the epidemiological, clinical, therapeutic and prognostic characteristics of this condition in a country with limited resources, for the improvement of prognosis and professional practice. Observation: This is a eutrophic newborn, born at term by vaginal delivery, who presented at birth with a unilateral absence of skin on the anteromedial aspect of the right leg starting from the knee and extending to the medial aspect of the right foot, with a dystrophy of the nail of the right big toe without any other visible physical malformation. The evolution was marked at D3 of life by the appearance of bullae on the right hand and elbow as well as on the posterior aspect of the neck, making epidermolysis bullosa suspect. The mother was 38 years old, 8th gesture, 7th pare with history of consanguinity and collodion baby. The association of a localized congenital absence of skin on the lower limbs, epidermolysis bullosa and a nail anomaly led to the diagnosis of congenital cutaneous aplasia of type VI of Frieden’s classification or Bart’s syndrome. The evolution was satisfactory on the 7th day of life with the beginning of scarring. The management was medical. The outcome was unfavorable with the appearance of sepsis and hemorrhage leading to death. Conclusion: Although rare, the clinical diagnosis of Bart’s syndrome is simple. However, the management is complex and the prognosis is reserved. To improve this prognosis, the treatment must guarantee excellent control of the infectious and hemorrhagic risks, an adhesion and good therapeutic compliance by the parents and a rigorous monitoring.

In addition to bioenergy production, Acacia magium, a fast growing species, plays a major role in climate change mitigation through carbon sequestration from the atmosphere. The objective of this study was to improve estimates of aboveground biomass of 3, 7 and 11 years old stands of Acacia mangium set up through natural regeneration at Anguédédou in C?te d’Ivoire. Tree measurements were done in circular plots of 615 m2 located at the center of each stand. 24 trees of circumference at breast height (cbh) between 31 and 116 cm were felled, weighed and measured. Multiple linear regressions were used to develop allometric equations linking aboveground biomass of trees to cbh and/or height. The carbon stock and sequestration capacity of each stand was assessed using these predictive models. The average cbh was 39.4 cm, 73.5 cm and 91.4 cm respectively for 3, 7 and 11 years old stands with a density ranging between 845 trees·ha-1 and 553 trees·ha-1. The allometric equations for biomass estimation were Btotal aboveground = exp(-3.455 + 2.081 × ln(C)), Btrunk = exp (-5.153 + 1.681 × ln(C) + 1.056 × ln(H)), Bbranches = exp(-2.005 + 0.498 × ln(C2 × H)), Bleaves = exp(-2.415 + 1.339 × ln(C)). Total height had no influence on total and leaf biomass but increased precision of trunk and branch biomass. The carbon sequestration capacity of aboveground biomass was highest in Acacia mangium stand of 7 years old with 45.14 teqCO2·ha-1·year-1 and lowest in the 3-year stand with 33.90 teqCO2·ha-1·year-1.
