Pa.ients over 15 yea.s of a.e a.mitted for occlusive syndrome in the two surgica. depa.tments of the Ziguinchor regiona. hospita.s were included in the study. Epidemiologica., dia.nostic, thera.eutic a.d evolutiona.y da.a.were studied. Results: a.ute intestina. occlusions a.counted for 8.3% of a.missions. a.tota. of 163 pa.ients were enrolled, 61.9% were men, sex ra.io of 1.6. The mea. a.e wa. 48.7 yea.s.

Biologica. la. tests reported hyperleukocytosis in 28.1% of the ca.es. a.domina. CT sca.s were performed in 71.2%, confirming the dia.nosis in 90.5% a.d determining the etiology in 93.1%. The zone of the obstruction in the sma.l bowel wa. 62.7%, a.d in the colon in 37.3%.

Introduction:?Congenita. a.rena. hyperpla.ia.(Ca.) is a.group of a.tosoma. recessive disea.es cha.a.terized by enzyma.ic deficiencies in the biosynthesis of a.rena. steroids. The most common 21-hydroxyla.e deficiency is cha.a.terized by a.cortisol deficiency a.d a. excess of a.drogens, with or without a.dosterone deficiency. In our countries, in the a.sence of neona.a. screening, the dia.nosis is most often la.e lea.ing to life-threa.ening complica.ions. The a.m of this study wa. to describe the dia.nostic fea.ures of Ca. a. the a.bert Royer Na.iona. Children’s Hospita. (a.NCH) in Da.a..?Pa.ients a.d method:?We conducted a.retrospective, descriptive study ca.ried out a. the pedia.ric endocrinology depa.tment of a.NCH from 2015 to 2019. a.l children a.ed under 15 with a.form of Ca. were included. Socio-demogra.hic da.a. fa.ily history, clinica. a.d biochemica. da.a.a. presenta.ion were collected. Pa.ients were noted a. presenting with Disorder of Sexua. Development (DSD) with dehydra.ion, DSD without dehydra.ion, dehydra.ion without DSD, precocious puberty. The Pra.er’s sca.e wa. used to determine the degree of externa. viriliza.ion. These da.a.were entered a.d a.a.yzed with Epi Info version 7.2.?Results:?a.tota. of 32 pa.ients were included, representing 74.41% of the ca.ses of disorder of sexua. development (DSD) a.d 84.21% of the ca.ses of a.rena. insufficiency. These were 27 girls (84.37%) a.d 5 boys (15.63%). The mea. a.e wa. 19 ± 34.6 months. DSD wa. the ma.n finding (87.5%). It wa. a.socia.ed with dehydra.ion in 22 ca.es (68.75%). 21-hydroxyla.e deficiency represented 93.75% of the ca.es with sa.t wa.ting in 73.33% of the ca.es.?Conclusion:?The dia.nosis of Ca. wa. dela.ed lea.ing to life-threa.ening a.rena. crises. In the a.sence of neona.a. screening for Ca. in Senega., there is a.need to tra.n hea.thca.e workers to recognize neona.es with DSD ea.ly a.d refer them timeously for specia.ist ca.e.
