The intellectual ability of patients with HFS is generally normal. This syndrome arises from variants of <jats:italic>ANTXR2</jats:italic>. Thus far, about 100 cases have been reported but few of these were reported from Japan.MethodsThis study reports five additional Japanese patients with genetically confirmed HFS, from unrelatd families, and discusses the clinical course and quality of life of these patients.ResultsAt our last visit the ages of the patients were 3–19 years (the median age was 5 years). All the patients had arthrogryposis, skin nodules, and gingival hyperplasia, and four patients had chronic pain, all of which are distinctive, clinical characteristics of HFS. Four of the patients (80%) had pruritic skin nodules, and three experienced sleep disruptions due to pruritis. The visceral complications are an index of HFS severity. One patient in the present cohort had a mucosal abnormality without any gastrointestinal symptoms.ConclusionPreventive and routine management of pruritis caused by skin nodules should be shared with the patient's family. Even asymptomatic patients might have endoscopic finding, which would be a soft marker that could predict the development of protein losing enteropathy.","PeriodicalId":20039,"journal":{"name":"Pediatrics International","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142176704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Usefulness of a mobile airwayscope with a monitor in examination of the external genitalia of a 483 g female neonate","authors":"Tairin Hiraizumi, Takeshi Sato, Hisato Kobayashi, Takeshi Arimitsu, Satoshi Narumi, Tomohiro Ishii, Tomonobu Hasegawa","doi":"10.1111/ped.15759","DOIUrl":"https://doi.org/10.1111/ped.15759","url":null,"abstract":"<p>Every neonate requires a detailed examination of the external genitalia for sex assignment. Conventional approaches for the examination in female extremely low birthweight (ELBW) neonates in the closed incubator are challenging. Under direct visual inspection from outside the closed incubator, evaluation may be insufficient, owing to the small body size. It is necessary to lift the lower limbs and buttocks to enable physicians to examine the perineum thoroughly. However, this practice is potentially against the minimal handling protocol for ELBW neonates. In a previous study, an endoscope-assisted technique helped physicians to identify the urethral meatus in a male ELBW neonate with hypospadias.<span>¹</span> It remains unknown whether this endoscope-assisted technique can be applied to examinations of perineum of female ELBW neonates. Here, using a mobile airwayscope with a monitor, we examined the external genitalia in a 483 g female neonate.</p>\u0000<p>The patient was born via vaginal delivery to a healthy mother at 22 weeks and 3 days of gestation due to impending preterm labor caused by cervical incompetence. The birthweight was 483 g (−0.78 SD). The patient was intubated and on mechanical ventilation in a closed incubator. The external genitalia of the patient were too small for adequate examination from outside the incubator (Figure 1a). On postnatal day 5, using a flexible mobile airwayscope, we examined the external genitalia of the patient remaining in the incubator for 7 min (Figure 1b). The mobile airwayscope (Olympus MAF-DM2, Olympus Corporation, Tokyo, Japan) had the following specifications: (i) a monitor allowing the inspector to manipulate the scope safely and effectively; (ii) a picture or video recording function; (iii) light emitting diode at the tip to illuminate objects; (iv) a 3.1 mm tip diameter, and (v) a length of 600 mm. During the mobile airwayscope-assisted examination, we identified a vaginal vestibule-like structure with no swelling of the labioscrotal folds; however, we could not identify the urethral meatus (Figure 1c). By retrospectively evaluating still images, the anogenital ratio and clitoral width were estimated to be 0.45, and 5.8 mm, respectively (Figure 1c,d). After the examination, the patient did not develop any fluctuations in vital signs or infectious diseases. Since the patient was not in good condition, abdominal ultrasonography for internal genitalia was not performed. We extracted DNA from the umbilical cords. A polymerase chain reaction revealed the absence of <i>SRY</i> (data not shown). Our medical differences of sex development team discussed the clinical information and results of the examinations, including images of the external genitalia. We shared the discussion and limitations with the parents, namely no reference ranges or normal findings in ELBW neonates' external genitalia. On postnatal day 11, the parents assigned and registered their baby's sex as female.</p>\u0000<figure><pict","PeriodicalId":20039,"journal":{"name":"Pediatrics International","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140626271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examined the risk factors and characteristics of COVID‐19 among pediatric patients compared to other respiratory viral infections.MethodsThis was a prospective cross‐sectional study. Patients aged 0–18 years presenting with respiratory symptoms from October 2020 to December 2021 were included. Demographic and clinical data were reviewed.ResultsIn total, 738 pediatric patients were enrolled. Of these, 48.5% had COVID‐19, and 41.3% were infected with another respiratory virus. The COVID‐19 incidence increased from 0.5% during the original strain outbreak (October 2020 to March 2021) to 56.5% and 73.4% during the alpha (April to June 2021) and delta (July to December 2021) periods, respectively. Children aged 6‐18 years, being female, obesity, exposure to household members with COVID‐19, and the delta period were risk factors for COVID‐19. Being aged 1‐5 years, obesity, shortness of breath, productive cough, and chest pain were associated with COVID‐19 pneumonia. Children aged 5–18 years, underlying neurological disease, a history of COVID‐19 pneumonia, and the delta period were associated with long COVID.ConclusionsPediatric COVID‐19 patients presenting with respiratory symptoms who are obese or have been exposed to household members with COVID‐19 should be tested for COVID‐19. COVID‐19 patients who are obese, younger than five years old, or who present with shortness of breath, productive cough, or chest pain should be evaluated for pneumonia. COVID‐19 patients with a history of COVID‐19 pneumonia or underlying neurological disease should receive follow‐up for long COVID.","PeriodicalId":20039,"journal":{"name":"Pediatrics International","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140625978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is important to understand the pathomechanism of monogenic diseases that are caused only by genetic factors, especially prenatal‐ or childhood‐onset diseases for pediatricians. Identifying “novel” disease genes and elucidating how genomic changes lead to human phenotypes would develop new therapeutic approaches for rare diseases for which no fundamental cure has yet been established. Genomic analysis has evolved along with the development of analytical techniques, from Sanger sequencing (first‐generation sequencing) to techniques such as comparative genomic hybridization, massive parallel short‐read sequencing (using a next‐generation sequencer or second‐generation sequencer) and long‐read sequencing (using a next‐next generation sequencer or third‐generation sequencer). I have been researching human genetics using conventional and new technologies, together with my mentors and numerous collaborators, and have identified genes responsible for more than 60 diseases. Here, an overview of genomic analyses of monogenic diseases that aims to identify novel disease genes, and several examples using different approaches depending on the disease characteristics are presented.","PeriodicalId":20039,"journal":{"name":"Pediatrics International","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140626057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
