The first step to eradicate thalassemia is to define population at risk. Aim of the work: to define the high risk population to be screened for thalassemia. Subjects and Methods: This observational cross-sectional study included children aged between 1 and 16 years presenting with microcytic anemia to Cairo university Children Hospitals from the period between March and September 2022. Children with hemoglobin <10mg/dL and mean red blood corpuscle volume (MCV) <70fl were included in the study. Complete blood count, serum ferritin, and hemoglobin electrophoresis were done. Results : Out of a total of 180 patients, 120 patients (66.7%) had iron deficiency anemia, 2 patients (1.1%) had alpha thalassemia, and 14 patients (7.7%) had beta thalassemia, 14 (7.7%) patients had thalassemia trait, 3 (1.67%) had sickle thalassemia, 7 (3.88%) had combined iron deficiency anemia (IDA) and thalassemia, and 20 (11.1%) required further investigations. Patients were divided according to MCV into 3 groups MCV<60, 60-65, >65. There was no significant difference in the diagnosis between the three groups. Conclusion : 22 % of children with MCV < 70 fl were found to have an inherited hemolytic anemia. Children with MCV <70 should be screened for thalassemia.","PeriodicalId":153483,"journal":{"name":"Pediatric Sciences Journal","volume":"BC-19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139259250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They present at any age, yet they are commoner in adults. They mainly affect face, neck, trunk and to a lesser extent groin, but can potentially arise as a subepidermal nodule anywhere on the body. They develop from the follicular infundibulum, and are different from dermoid cysts as epidermoid cysts do not contain other adnexal structures of embryonic origin. Epidermoid cysts are mostly silent but can rupture, get inflamed, become infected or develop daughter cysts. Very rarely epidermoid cysts develop in proximity to testicles. They can be mistaken for a testicular tumor. The pre-operative diagnosis is essential to avoid unindicated testicular surgery. Magnetic resonance imaging (MRI) is vital for diagnosis. We report a 6-year-old child with a long standing painless scrotal swelling thought by the parents to be polyorchidism. They were alarmed by its recent rapid growth. By examination it was a median raphe cyst. Pre-operative imaging and operative surgical removal proved it to be an inflamed epidermoid cyst. The surgery was uncomplicated and the child had an uneventful recovery. Testicular epidermoid cysts in children are exceptionally rare, yet they can present as median raphe cysts. Inflammation within the epidermoid cyst presents clinically as rapid painless growth. Clinical examination, high index of suspicion and pre-operative MRI avoid unnecessary testicular surgery.","PeriodicalId":153483,"journal":{"name":"Pediatric Sciences Journal","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133963539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Electric cardiometry (EC) is not suitable for diagnosis, but its value in monitoring changes in cardiac parameters over time is in need of verification. Aim of the Work: To study EC hemodynamic parameters predictive ability of outcome in full-term newborns with RD. Materials and Methods: using electric cardiometry (EC) hemodynamic parameters were studied among 30 full term neonates with RD within the first 10 minutes of life and 2 hours later compared to another 30 without RD. The studied parameters were heart rate variability (HRV), cardiac output (CO), cardiac index (CI), stroke volume (SV), stroke index (SI), thoracic fluid content (TFC), stroke volume variation (SVV), index of contractility (ICON), left ventricular (LV) pre-ejection period (PEP), ejection time (ET), and systemic vascular resistance (SVR). Results: The mean ± SD gestational age of the studied group was 38.20 ± 1.19 weeks, weight was 3.03 ± 0.51 kilogram, females were 15 (50%), and males were 15 (50%) which was comparable to the control group (p=0.584), (p=0.284) and (p=0.436) respectively. The mean Apgar score was less among the RD group; at one minute it was 6 and at 5 minutes was 8 (p=0.0001) and (p=0.002).

It was first described by Claudius Amyand, in 1735 during an appendectomy of a perforated appendix inside a hernial sac of an 11-year old child. Amyand hernia rare, constituting less than 1% of inguinal hernias. Amyand hernia is 3 times more likely to be diagnosed in children compared to adults due to the patency of vaginal process. Appendicitis or its perforation in Amyand hernia, complicate 0.1% of cases. Other variants include the presence of ileum, caecum or both in addition to the appendix. Isolated acute appendicitis in neonates is extremely rare, with a high mortality rate, and higher among those within Amyand hernia up to 30%. Perforated appendix in Amyand hernia is difficult to diagnose, as its clinical picture is not specific. We report a neonate 26 days old with perforated appendix in an Amyand inguinal hernia who presented by a picture of obstructed oblique inguinal hernia. He underwent emergency open inguinal exploration, herniotomy and appendicectomy. Despite the high mortality rate of Amyand hernia due to be peritoneal spread of sepsis, the boy survived complication free. Perforated appendix in Amyand hernia is exceptionally rare, and can present in the early neonatal period, its diagnosis and outcome rely on high index of suspicion and prompt surgical intervention.","PeriodicalId":153483,"journal":{"name":"Pediatric Sciences Journal","volume":"208 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126014122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aim of the work: To assess the hearing ability and cognitive functions in patients with SCD. Material and methods: a cross sectional case-control study included 41 children with SCD who presented to Pediatric Hematology Clinic, Children Hospital, Cairo University. They were screened for auditory impairment using tympanometry and pure tone audiometer (PTA), they were also assessed for cognitive impairment using the Stanford-Binet Intelligence Scale, 4th Ed, and P300 event related auditory evoked potential. Another 41 healthy age and gender matched children were enrolled as controls for P300 data. Results: The age of the children with SCD ranged from 6-17 years (mean± SD= 10.4±3.3 year), 15 (36.6%) were males and 26 (63.4%) females. Nine (22%) had impaired hearing detected by PTA. The cognitive dysfunction was encountered in 33 (80.5%) patients with SCD. The greater impairment was observed in older patients (p=0.082), and in those with hemoglobin SS type (p<0.05). Twelve (29.3%) patients had abnormal P300 latency. P300 latency was higher (p=0.002) and amplitude was lower (p=0.008) in patients aged <10 years compared to their controls. 33 (80.5%) patients had low IQ ( ˂ 89), they had a significant lower P300 amplitude (p=0.004) but comparable latencies (p=0.3) to patients with normal IQ.
