ABSTRACT
The clinical picture of SARS-CoV-2 infection is variable, ranging from moderate to severe and critical forms. Various studies have shown that disturbances in certain biochemical parameters are correlated with the severity of the disease. They can be used to predict the risk of complications, allowing early and appropriate care of these patients. The aim of our study is to evaluate the correlation between admission ferritin levels and mortality in COVID-19 patients. We used data from the records of patients with positive RT-PCR admitted to the Mohamed V Military Training Hospital in Rabat between april 2020 and december 2021. Demographic and biologic data were exctracted from DxLab LIS of Dedalus. 1.310 patients are included; the average age is 56 years and 72% of patients are male. The all-cause mortality of seriously ill hospitalized patients in the intensive care units are 23%. 73% of patients who died were over 60 years. The mean ferritinemia at admission was 2040 ng/ml for patients who died versus 521 ng/ml for the survivors (p <0.01). The AUC of the ROC curve for ferritin levels predicting all-cause mortality is 0.745. The threshold of 800 ng/ml allows a sensitivity of 72% and a specificity of 30%. Logistic regression analysis showed that ferritin levels above 800 ng/ml and age above 60 years are risk factors for mortality (p<0.01) independently of each other. At hospitalisation of COVID-19 patients, high ferritin levels would be correlated with a bad prognosis justifying an early and adapted care of these patients.

ABSTRACT
Hirschsprung's disease is a congenital anomaly of the innervation of the distal intestine, usually limited to the rectum and colon, resulting in partial or total functional occlusion. It is one of the most common causes of obstruction in children. It is a rare pathology, but the diagnosis of which is becoming increasingly easy because of dill Omo pathology. We report two cases treated urgently in the pediatric surgery department of the Fousseyni Daou hospital in Kayes. Our objectives were to describe the clinical aspects and the management of an occlusive syndrome secondary to Hirschsprung's disease.

ABSTRACT
Ship sanitation is one of the efforts at environmental risk factors on ships to break the chain of disease transmission in order to maintain and enhance health status .Poor ship sanitation will cause many problems in terms of physical, health, aesthetics and human survival The aim of this study is to know the description of the sanitation conditions on passenger ships that docked at the Kupang Tenau Port in 20 22. The type of this study is descriptive. Population in this study is all passenger ships that dock at the Port of Tenau Kupang from 4 to 17 March 2022 totaling 8 vessels. Accidental Sampling is a technuque for taking sample in this study (which is coincidenceany) totaling 8 ships. Instrument in this study used form of sanitation inspection from Health Office shipport. The results showing that on deck sanitation aspect there are 2 (25%) ships no fulfil condition on aspect cleanliness and good was neatly arranged and 6 (75%) ships fulfil terms. On aspect sanitationof crew member's room and passenger's room there are 5 (62.5%) not fulfil condition on aspect cleanliness and 3 (37.5%) ships fulfil terms. On aspect sanitation bathroom and tailet 8 (100%) boats no fulfil condition on aspect no smells fierce, 1 (12.5%) no fulfil condition on aspect good function and 8 (100%) ships fulfil condition on aspect cleanliness, not a place to store goods and there are no insects. On aspect sanitation kitchenof the 4 ships made inspection whole boat no fulfil condition on aspect wash equipment with hot water and 3 (75%) ships not have trash cover. On aspect sanitation room cooler thera are 4 (100%) vessels full conditions (100%). On aspect sanitation warehouse supply boat there are 1 (25%) ship no fulfil condition on aspect cleanliness and 3 (75%) ships fulfil terms. On aspect sanitation handler food there are 4 (100%) ships fulfil conditions (100%). On aspect sanitation clean water supply there are 8 (100%) vessels full conditions (100%). Conclusion from 8 (100%) ships ther

ABSTRACT
Intussusception is a condition characterized by the penetration of one segment of the intestine into another. It is a medical emergency characterized by bowel obstruction. It can be fatal if left untreated, and occurs most often in children. It is a fairly common pathology in our country with seasonal peaks. The objective of this study is to describe the diagnostic and therapeutic clinical epidemiological aspects of intussusception in infants and children in the pediatric surgery department of Fousseyni Daou hospital. Material and methodology: This is a retrospective study which took place from January 2019 to December 2021 at the Fousseyni Daou hospital in Kayes and included in this study all children operated on for intussusception from 0 to 15 years, through the use of patient records. Results: During the study period, we operated on 975 patients, including 63 occlusions and 27 intussusceptions, i.e. 2.76% of operations and 42.85% of occlusions. The male sex was the most represented 18 cases or 66.66%. There was the notion of abdominal pain in all patients, vomiting in 18 patients and rectal bleeding in 7 patients. At the clinical examination the sausage was found in 18 patients, a standard blood test was carried out in all the patients. Ultrasound was the main radiological examination to confirm intussusception. Treatment was surgical in all patients, with resection. Anastomosis in 6 cases due to late management of these patients. In the immediate postoperative course, we noted two surgical site infections and one eventration. Conclusion: Intussusception is a fairly common pathology in our region, but the evolution of which depends on the promptness of treatment.

ABSTRACT
Meckel's diverticulum is the partial persistence of the mesenteric omphalos canal. It is the most common congenital anomaly of the gastrointestinal tract with a slight male predominance [1, 8, 9 ]. It is a fairly rare pathology in our region. Its discovery is most often fortuitous, but it can be the basis of several digestive complications: peritonitis by perforation or occlusion, digestive hemorrhage, diverticulum. We report a case of Meckel's diverticulum discovered following chronic umbilical care in a two-year-old child. The objective is to describe this rare clinical case and discuss the therapeutic and evolutionary aspects.
