Blood transfusion in the neonatal period remains a therapeutic act, that no one dares to consider it as perfectly innocuous and that it is advisable to make rare, considering its risks as well immunological as infectious. The present work is a retrospective study, conducted in neonatal intensive care unit, in the University Hospital MOHAMED VI, Marrakech, during the period from January 1^st to December 31^st, 2019. All newborns were included in this work, who received one or multiple transfusions of red blood cells (RBC). Our study covered 60 neonates with a total of birth: 794 neonates, with a prevalence of 7.55%, hospitalized for various indications (60% of newborns were at term, 31.7% premature and 8, 33% were post-mature. The majority of transfusion procedures were performed during the first week of life. This is explained by the frequency of haemolytic anemias by fœto-maternal incompatibility. The main indications for transfusion were haemolysis, anemic syndrome and haemorrhagic syndrome. The average number of transfusion episodes was 1.95 +/- 1.47 per patient. Newborns were polytransfused in 18.33% of cases. A single transfusion accident was found in our study. However, we did not observe a correlation between the maternal diseases, the state of the newborn, and the transfusional indication.

For the purpose to analysis the characteristics of traffic accidents(TA) and investigate the relationship between traffic accidents and children attention problem rating scale(CAP) and, family environment scale(FES), this questionnaire survey was conducted to the 16 primary school students in Taejon from July 14 to August 26, 1997. The number of study subjects who had an experience of traffic accidents from July 1, 1996 to June 30, 1997 were 195, and the number of control sujects were 512. The main results were as follows; 1. The traffic accident rates was 0.9% as a whole, but those were 1.4% in boys, 0.7% in girls, 1.3% in low (1st-3rd) grade, and 0.8% in high (4th-6th) grade. 2. The rates of traffic accidents were high in spring, friday, afternoon and a drive-way around home. TA occurred during walking with friends most frequently. 3. In CAP the score of inattention was lower in TA group than control group, and hyperactivity was higher in TA group but they didn't showed significantly different. In FES, cohesion score was higher in TA group than control group, but Conflict score and Expressiveness score were in control group, but they didn't showed significantly different. 4. In CAP the odds ratio of inattention score for TA group was 0.84, but that of hyperactivity score was 1.15. In FES, the odds ratio of cohesion score was 1.06, but that of expression score and conflict score was 0.94 and 0.96, respectively. In conclusion, the relationships between TA and CAP, TA and FES in this study were not clear to explain personal characteristics and environmental conditions.

Traumatic ventricular septal defect (VSD) resulting from blunt chest injury is a very rare event. The mechanisms of traumatic VSD have been of little concern to dateuntil now, but two dominant theories have been described. In one, the rupture occurs due to acute compression of the heart; in the other, it is due to myocardial infarction of the septum. The clinical symptoms and timing of presentation are variable, so appropriate diagnosis can be difficult or delayed. Closure of traumatic VSD has been based on a combination of heart failure symptoms, hemodynamics, and defect size. Here, we present a case of a 4-year-old boy who presented with a traumatic VSD following a car accident. He showed normal cardiac structure at the time of injury, but after 8 days, his repeated echocardiography revealed a VSD. He was successfully treated by surgical closure of the VSD, and has been doing well up to the present. This report suggests that the clinician should pay great close attention to the patients injured by blunt chest trauma, keeping in mind the possibility of cardiac injury.

Resuscitative endovascular balloon occlusion of the aorta (REBOA) is considered an emerging adjunct therapy for profound hemorrhagic shock, as it can maintain temporary stability until definitive repair of the injury. However, there is limited information about the use of this procedure in children. Herein, we report a case of REBOA in a pediatric patient with blunt trauma, wherein the preoperative deployment of REBOA played a pivotal role in damage control resuscitation. A 7-year-old male patient experienced cardiac arrest after a motor vehicle accident. After 30 minutes of cardiopulmonary resuscitation, spontaneous circulation was achieved. The patient was diagnosed with massive hemoperitoneum. REBOA was then performed under ongoing resuscitative measures. An intra-aortic balloon catheter was deployed above the supraceliac aorta, which helped achieved permissive hypotension while the patient was undergoing surgery. After successful bleeding control with small bowel resection for mesenteric avulsion, thorough radiologic evaluations revealed hypoxic brain injury. The patient died from deterioration of disseminated intravascular coagulation. Although the patient did not survive, a postoperative computed tomography scan revealed neither remaining intraperitoneal injury nor peripheral ischemia correlated with the insertion of a 7-Fr sheath. Hence, REBOA can be a successful bridge therapy, and this result may facilitate the further usage of REBOA to save pediatric patients with non-compressible torso hemorrhage.
