The biopsy confirmed limited cutaneous panniculitic T-cell lymphoma with extensive epidermal necrosis.Conclusions: We report the case of a SPTCL in a child.

Cardiogenesis is a highly complex process that requires the active and orderly participation of different cardiac and non-cardiac cell populations. Thus, this process is sensitive to errors that may trigger a variety of heart-development defects, called congenital heart defects, which have a worldwide incidence of 8-10/1000 live births. A good understanding of normal cardiogenesis is required for better diagnosis and treatment of congenital heart diseases. This article reviews normal cardiogenesis by comparing information from classic studies with more recent findings. Information from descriptive anatomical studies of histological sections and selective in vivo marking of chicken embryos were emphasized. In addition, the discovery of heart fields has fueled the investigation of cardiogenic events that were believed to be understood and has contributed to proposals for new models of heart development.","PeriodicalId":9103,"journal":{"name":"Boletín médico del Hospital Infantil de México","volume":"80 2","pages":"79-93"},"PeriodicalIF":0.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9658192","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}

Persistence of fetal vasculature (PFV) is within the differential diagnosis of leukocoria, a vitreous disorder arising from a defect in the involution of the hyaloid vasculature in the embryonic stage, which affects normal ocular development and commonly produces associated microophthalmia.

Lymphatic endothelial cell proliferation depends on several growth factors that use the phosphoinositide-3 kinase (PI3K)/Akt pathway and converge on the mammalian target molecule of the rapamycin (mTOR) pathway. These findings have allowed treating GSD with mTOR pathway inhibitors such as sirolimus or everolimus.Case report: We present the case of a one-year-old female patient referred to our institution after a right femur fracture and progressive limb volume increase, disproportionately to the trauma. After several episodes of soft tissue infections, imaging studies showed pseudarthrosis, lytic lesions, and progressive loss of the right femur that ended in total absence. A femur biopsy showed lymphatic structures positive with D2-40 staining, diagnosing GSD. After six months of non-response to traditional treatments, the limb was disarticulated at the hip level, and oral sirolimus treatment was initiated, showing clinical and radiological improvement with minor lytic lesions and evidence of ossification after 20 months of treatment.Conclusions: Oral sirolimus treatment for GSD inhibits angiogenesis and osteoclastic activity, stimulating bone anabolism and leading to arrested osteolysis progression and improved ossification, quality of life, and patient prognosis. Therefore, sirolimus should be considered a therapeutic option for this rare disease.","PeriodicalId":9103,"journal":{"name":"Boletín médico del Hospital Infantil de México","volume":"80 3","pages":"217-221"},"PeriodicalIF":0.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9893120","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}

The percentage of hospitalization and death in COVID-19 patients with and without comorbidities was 3.52%, and 0.20%, respectively; children with comorbidities presented a higher percentage of hospitalization (14.0%) and death (1.9%). The probability of hospitalization was 5.6 times greater in pediatric patients with COVID-19 and comorbidities, and the comorbidities that showed the greatest risk were immunosuppression (odds ratio (OR) 22.06), chronic kidney disease (CKD) (11.36), and cardiovascular diseases (5.66).

They were initially described as renal tumors, although tumors with the same histopathological and immunohistochemical characteristics have been discovered in other locations, mainly in the central nervous system. Few cases of mediastinal location have been reported internationally. This work aimed to describe the case of a mediastinal rhabdoid tumor.Case report: We describe the case of an 8-month-old male patient admitted to the pediatric department with dysphonia and laryngeal stridor progressing to severe respiratory distress. Contrast-enhanced computed tomography of the thorax showed a large mass with homogeneous soft tissue density, and smooth and well-defined borders, with suspicion of malignant neoplasm. Due to the oncological emergency compressing the airway, empirical chemotherapy was initiated. Subsequently, the patient underwent incomplete tumor resection due to its invasive nature. The pathology report showed morphology compatible with a rhabdoid tumor, which immunohistochemical and genetic studies corroborated. Chemotherapy and radiotherapy to the mediastinum were administered. However, the patient died three months after the initial treatment due to the aggressive behavior of the tumor.Conclusions: Rhabdoid tumors are aggressive and malignant entities difficult to control and have poor survival. Early diagnosis and aggressive treatment are required, although the 5-year survival does not exceed 40%. It is necessary to analyze and report more similar cases to establish specific treatment guidelines.","PeriodicalId":9103,"journal":{"name":"Boletín médico del Hospital Infantil de México","volume":"80 1","pages":"63-68"},"PeriodicalIF":0.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9491384","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}

Hydrogel beads are used as sensory and didactic toys that can increase their initial size 200 to 400 times by liquid absorption. An abdominal X-ray was perfomed in anteroposterior supine projection, where a round filling defect at the loop of the right flank was detected; this came to our attention because hydrogel beads are usually radiolucent. The diagnosis was established by abdominal ultrasound where free intraperitoneal fluid was reported with data of small bowel pseudo-obstruction by foreign objects. Conservative treatment was prescribed, finding persistence of increased abdominal perimeter, so an enterotomy was performed for their removal; finding impacted hydrogel beads 30 centimeters from the ileocecal valve.Conclusions: Hydrogel beads are dangerous for the pediatric population.
