This review aims to present a comprehensive synthesis of the existing treatment modalities for keratosis pilaris (KP) and evaluate their therapeutic efficacy. KP is a prevalent chronic dermatological condition typified by its unique 'chicken skin appearance', with the cheeks being the most commonly involved sites. Numerous therapeutic interventions have emerged, given its substantial prevalence and impact on skin aesthetics and psychological wellbeing. Nonetheless, a consistent therapeutic response has been challenging to achieve. This review endeavours to collate and critically appraise the current treatment landscape for KP. An exhaustive literature search was performed using databases such as Ovid, PubMed and Scopus. From an initial count of 459 articles identified after deduplication, 52 were selected for inclusion after a thorough full-text examination for articles with concrete outcome data highlighting the efficacies of different therapeutic modalities; articles that lacked data or were tangential to the core focus on KP treatment were excluded. The included articles were then catalogued based on the nature of treatment strategies and their respective outcomes. Among the various therapeutic interventions, laser and light modalities appear to be supported by the most substantial evidence base. Notably, the Nd:YAG (neodymium-doped yttrium-aluminium-garnet) laser, attributed to its longer wavelength, emerged as a preferred option. While other therapeutic avenues have also exhibited notable improvements in skin texture and discolouration relative to baseline, the inconsistency in outcome measures underscores the need for a standardized, KP-specific scoring system to foster a more coherent comparison across treatments. Based on the current evidence, Nd:YAG laser therapy demonstrates promising effectiveness with a relatively favourable side-effect profile. However, the landscape of KP treatment is multifaceted, and further studies are essential to solidify recommendations., Competing Interests: Conflicts of interest The authors declare no conflicts of interest., (© The Author(s) 2024.

Hirschsprung disease (HSCR) and its associated disorders (AD-HSCR) often result in severe hypoperistalsis caused by enteric neuropathy, mesenchymopathy, and myopathy. Notably, HSCR involving the small intestine, isolated hypoganglionosis, chronic idiopathic intestinal pseudo-obstruction, and megacystis-microcolon-intestinal hypoperistalsis syndrome carry a poor prognosis. Ultimately, small-bowel transplantation (SBTx) is necessary for refractory cases, but it is highly invasive and outcomes are less than optimal, despite advances in surgical techniques and management. Thus, regenerative therapy has come to light as a potential form of treatment involving regeneration of the enteric nervous system, mesenchyme, and smooth muscle in affected areas. We review the cutting-edge regenerative therapeutic approaches for managing HSCR and AD-HSCR, including the use of enteric nervous system progenitor cells, embryonic stem cells, induced pluripotent stem cells, and mesenchymal stem cells as cell sources, the recipient intestine's microenvironment, and transplantation methods. Perspectives on the future of these treatments are also discussed., (© 2023. The Author(s) under exclusive licence to Springer Nature Singapore Pte Ltd.)

Megacystis microcolon intestinal hypoperistalsis syndrome (MMIHS) is a rare, congenital functional intestinal obstruction, characterised by megacystis (bladder distention in the absence of mechanical obstruction), microcolon and intestinal hypoperistalsis (dysmotility).We are reporting a case of a female child with normal antenatal course who presented with recurrent episodes of abdominal distension since the second day of life and underwent negative exploratory laparotomy on multiple occasions. She also had urinary retention with a grossly distended bladder, requiring drainage by clean intermittent catheterisation. Surgical procedures for bowel decompression, including gastrostomy and ileostomy, were carried out without success. Genetic analysis revealed a mutation in the human smooth muscle (enteric) gamma-actin gene (ACTG2 gene), clinching the diagnosis of MMIHS. The patient was managed with parenteral nutrition and prokinetic medications and tolerated jejunostomy feeds for a brief period before she succumbed to the illness.Female neonates or infants presenting with abdominal distension and dilated urinary tract should be investigated for MMIHS early on. A timely diagnosis will enable the early involvement of a multidisciplinary team to provide the best options available for management., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024.

Joubert syndrome (JS; MIM PS213300) is a rare genetic autosomal recessive disease characterized by cerebellar vermis hypoplasia, a distinctive malformation of the cerebellum and the so-called "molar tooth sign." Other characteristic features are hypotonia with lateral ataxia, intellectual disability/mental retardation, oculomotor apraxia, retinal dystrophy, abnormalities in the respiratory system, renal cysts, hepatic fibrosis, and skeletal changes. Such pleiotropic characteristics are typical of many disorders involving primary cilium aberrations, providing a significant overlap between JS and other ciliopathies such as nephronophthisis, Meckel syndrome, and Bardet-Biedl syndrome. This review will describe some characteristics of JS associated with changes in 35 genes, and will also address subtypes of JS, clinical diagnosis, and the future of therapeutic developments., (© 2022 Lidvana Spahiu et al., published by Sciendo.)

A full-term female infant was admitted at 5 hours after birth due to heart malformations found during the fetal period and cyanosis once after birth. Mmultiple malformations of eyes, face, limbs, and heart were noted. The whole-exome sequencing revealed a pathogenic heterozygous mutation, c.2428C>T(p.Arg810 * ), in the BCOR gene. The infant was then diagnosed with oculo-facio-cardio-dental syndrome. He received assisted ventilation to improve oxygenation and nutritional support during hospitalization. Right ventricular double outlet correction was performed 1 month after birth. Ocular lesions were followed up and scheduled for elective surgery. The possibility of oculo-facio-cardio-dental syndrome should be considered for neonates with multiple malformations of eyes, face, and heart, and genetic testing should be performed as early as possible to confirm the diagnosis; meanwhile, active ophthalmic and cardiovascular symptomatic treatment should be given to improve the prognosis.

Introduction: Keratosis pilaris (KP) is a common, benign skin condition of follicular hyperkeratosis. Although KP is asymptomatic, the cosmetic appearance of KP can lead to psychosocial distress among patients. New emerging treatments are increasingly being utilized. Yet, there is little to no summative data on the treatments of KP and its subtypes., Objective: To summarize existing literature on treatments for KP and its subtypes., Methods: A comprehensive search was performed using Pubmed/MEDLINE, Embase and Web of Science databases. The search identified 1150 non-duplicated articles, and 47 articles were included in the review. The primary outcomes measured were KP treatment type and the degree of improvement following therapy., Findings: Our findings demonstrate that the most supported form of treatment for KP is laser therapy, particularly the QS:Nd YAG laser. Topical treatments - including Mineral Oil-Hydrophil Petrolat, tacrolimus, azelaic acid, and salicylic acid - are also effective at least for improving the appearance of KP., Conclusion: While the measured treatment outcomes varied among studies, laser therapy appears to be the most effective form of treatment. Use of topicals also improved KP lesions.

Kabuki syndrome (KS) is a rare congenital disorder commonly complicated by humoral immunodeficiency. Patients with KS present with mutation in the histone-lysine N-methyltransferase 2D (KMT2D) gene. Although various KMT2D mutations are often identified in lymphoma and leukemia, those encountered in aplastic anemia (AA) are limited. Herein, we present the case of a 45-year-old Japanese man who developed severe pancytopenia and hypogammaglobulinemia. He did not present with any evident malformations, intellectual disability, or detectable levels of autoantibodies. However, B-cell development was impaired. Therefore, a diagnosis of very severe AA due to a hypoplastic marrow, which did not respond to granulocyte colony-stimulating factor, was made. The patient received umbilical cord blood transplantation but died from a Pseudomonas infection before neutrophil engraftment. Trio whole-exome sequencing revealed a novel missense heterozygous mutation c.15959G >A (p.R5320H) in exon 50 of the KMT2D gene. Moreover, Sanger sequencing of peripheral blood and bone marrow mononuclear cells and a skin biopsy specimen obtained from this patient identified this heterozygous mutation, suggesting that de novo mutation associated with KS occurred in the early embryonic development. Our case showed a novel association between KS mutation and adult-onset AA., (© 2021 S. Karger AG, Basel.)

Background: Clubfeet and constriction band syndrome is a very rare non-idiopathic condition. Treatment is often difficult and the recurrence deformity rate is high. The purpose of this study was to assess the effectiveness of Ponseti method in the treatment of congenital constriction band syndrome accompanied by clubfoot deformity and lymphedema., Case Presentation: We are presenting an interesting case of bilateral clubfeet and congenital circumferential constriction band syndrome in the lower limb. Ponseti method of correcting the congenital clubfoot deformity was applied. Constriction band release is accomplished by two stages completely excising the fibrous band and multiple two-stage Z-plasties on the right calf., Conclusion: The results of this study indicate that the Ponseti method of gentle, systematic manipulation and weekly cast changes is an effective treatment of non-idiopathic clubfoot distal to congenital amniotic constriction band.

Mucopolysaccharidosis type I is a rare autosomal recessive genetic disease caused by deficient activity of α-L-iduronidase. As a consequence of low or absent activity of this enzyme, glycosaminoglycans accumulate in the lysosomal compartments of multiple cell types throughout the body. Mucopolysaccharidosis type I has been classified into 3 clinical subtypes, ranging from a severe Hurler form to the more attenuated Hurler-Scheie and Scheie phenotypes. Over 200 gene variants causing the various forms of mucopolysaccharidosis type I have been reported. DNA isolated from dried blood spot was used to sequencing of all exons of the IDUA gene from a patient with a clinical phenotype of severe mucopolysaccharidosis type I syndrome. Enzyme activity of α-L-iduronidase was quantified by fluorimetric assay. Additionally, a molecular dynamics simulation approach was used to determine the effect of the Ser633Trp mutation on the structure and dynamics of the α-L-iduronidase. The DNA sequencing analysis and enzymatic activity shows a c.1898C>G mutation associated a patient with a homozygous state and α-L-iduronidase activity of 0.24 μmol/L/h, respectively. The molecular dynamics simulation analysis shows that the p.Ser633Trp mutation on the α-L-iduronidase affect significant the temporal and spatial properties of the different structural loops, the N-glycan attached to Asn372 and amino acid residues around the catalytic site of this enzyme. Low enzymatic activity observed for p.Ser633Trp variant of the α-L-iduronidase seems to lead to severe mucopolysaccharidosis type I phenotype, possibly associated with a perturbation of the structural dynamics in regions of the enzyme close to the active site.

Introduction and Objectives: The purpose of this study was to evaluate patients diagnosed with 22q11.2 deletion syndrome and determine the clues directing to diagnosis and evaluation of immunological findings for excellent management of the disease., Material and Methods: Thirty-three pediatric patients with 22q11.2 deletion syndrome diagnosed between 1998 and 2019 at Pediatric Immunology Division of Ege University Faculty of Medicine and SBU Izmir Dr Behcet Uz Children's Education and Research Hospital were evaluated., Results: This study includes the largest case series reported from Turkey. Congenital cardiac anomalies were the most common pathology associated with the syndrome (90.9%). Hypocalcemic symptoms were observed in 13 patients (40%). Twenty-two of the 33 (66.6%) patients were diagnosed before two years of age. Autoimmune diseases, dysmorphic facial findings, recurrent infections, growth retardation, and speech impairment were other clues for diagnosis in older patients. Clinical spectrum and immunological abnormalities of this syndrome are quite variable. All T-cell subset counts were less than 5th percentile below median by age in one patient (3%) and 10 patients had normal all T-cell subset counts (30.3%). Overall, 69.6% of the patients had normal IgG, IgA, and IgM levels and two patients had panhypogammaglobulinemia. Recurrent infections were revealed in 75.7% of the patients during follow-up., Conclusions: Presence of cardiac anomaly is more helpful in the diagnosis, especially under two years of age. Patients with immunologically high or standard risk did not show any difference in terms of numbers and severity of infections and autoimmunity., Competing Interests: The authors declare that they have no conflict of interest.

The treatment of patients with colorectal disorders and their associated urologic, gynecologic, gastrointestinal, spinal, and orthopedic anomalies requires care from various medical and surgical specialties over the course of their lifetime. This is ideally handled by a collaborative center which facilitates the assessment and development of a long-term patient care plan among multiple specialties which can enhance the quality of care, improve communication among different specialties, and improve patient satisfaction and outcomes. We describe the process, as well as lessons learned in developing such a center., (Copyright © 2020. Published by Elsevier Inc.)

Anorectal malformations (ARM) are well recognized to be associated with anomalies in other organ systems. The introduction of screening protocols has increased the diagnosis of these anomalies and greater collaboration with other specialties has influenced the treatment and follow-up of patients with ARMs. Much of the medical literature regarding the treatment of anorectal malformations has focused on technical details of operations and early post-surgical outcomes. Recently, an increase in published data regarding the long-term sequelae of an ARM diagnosis has resulted in an emphasis extended follow up in this population. Patient support groups have highlighted complex issues in ARM patients persist into adulthood have advocated for improved transitional care. This article describes the benefits of long-term follow-up and identifies key issues in ARM patients with respect to urologic and gynecologic health. A collaborative model of care is outlined and suggested timings of screening for potential problems is described., (Copyright © 2020. Published by Elsevier Inc.)

During this early part of the 21st century online technology has prompted many major advances in medical care. In this section we argue that this is particularly evident in the treatment and care of patients born with Anorectal Malformation (ARM) and Hirschsprung's Disease (HD). Our stories show that anyone born with these complex colorectal conditions in the 20th century was destined to a life of isolation and stigma. Here we explore the lack of understanding and recognition of the psychological effects on children and families which has characterised this period. We show that advances in clinical practice has been supported by developing social media platforms. There has been a rapid creation of online support groups for patients and families which has enabled survivors' greater access to patient and parent organizations across the globe and thereby stimulated a sense of belonging and solidarity. Online technology and social media platforms have also opened up the opportunity for pediatric medical professionals to provide a greater level of patient education. There is no doubt families have become much more aware of the complexities of ARM & HD and achieved greater comfort and understanding of their needs. We have generated "lightbulb moments" for pediatric providers with adult ARM & HD patients, enabling them to share their lived experiences in a therapeutic exchange. In the past survivors felt they were abandoned by the adult healthcare system. We are seeing evidence-based research of major psychosocial issues experienced by adult patients and, as a result, improved understanding of how to treat ARM & HD survivors across their whole of life journey. The winds of change continue to direct our cohorts to a mature approach based on improving levels of interactive communication and education. We argue that this maturity has mostly been facilitated by the use of online technology and the ensuing collaboration between providers and patient and parent organizations., (Copyright © 2020.

Stüve-Wiedemann syndrome (SWS) is a rare genetic disorder characterized by skeletal dysplasia and severe dysautonomia, evidencing a difficult airway approach and likely increased malignant hyperthermia susceptibility. Developmental dysmorphism classically worsens with age, therefore translating in a poor prognosis. In this article, we describe a case of a 27-year-old woman diagnosed with SWS proposed for abscess drainage under dissociative anesthesia. This patient has outlived the life expectancy described for SWS, acknowledging the importance of reporting this rare adult clinical case in what SWS anesthetic management is concerned.

Background: Keratosis pilaris (KP) is a common hereditary keratinization disorder. Keratosis pilaris rubra and KP atrophicans faciei are less frequent variants of the disease. Topical treatments often yield ineffective and temporary results., Objective: The objective of this article is to review and assess all the studies that used light and laser devices to treat KP and its variants., Material and Methods: On January 15, 2017, an online search of the MEDLINE, Embase, and Cochrane databases was performed using the following combination of keywords: "keratosis pilaris" and "treatment.", Results: Seventeen studies related to light and laser treatments were retained for analysis. The total number of treated patients was 175. Of which, 22 patients had KP atrophicans faciei, 17 patients had KP rubra, and 136 patients had KP., Conclusion: Light and laser devices have been emerging as promising therapeutic options for a disfiguring disease that still lacks, until today, an effective long-term treatment.

Introduction: In Chile, Down syndrome has a prevalence of 2.5 in 1,000 live births. These patients present more congenital anomalies and comorbidities than the general population, increasing their hospitaliza tion rate., Objective: To describe congenital anomalies and comorbidities of neonates with Down syndrome born and/or hospitalized between 2008 and 2018., Patients and Method: We conducted a retrospective review of patient's medical records born and/or hospitalized during their first 28 days of life between January 1st, 2008, and December 31st, 2018. For each patient, we recorded maternal age, familiar cases of Down Syndrome, pre and perinatal history, genetic study result, as well as age at admission, reason for hospitalization, comorbidities, length of stay, and death. Two patients that had more than 50% of incomplete medical records were excluded. We studied the associations between comorbidities, congenital anomalies, and death., Results: 140 in 79,506 newborns (0.2%) were diagnosed at our center with Down Syndrome in their neonatal period. 24.7% were born preterm and 26.4% had low birth weight for gestational age. Morbidities and hospitalizations were present in 83.6% and 90%, of the study population, respectively. The main reason for hospitalization was polycythemia and the most frequent was hyperbilirubinemia. Four patients died (2.9%) and 70.7% presented at least one congenital anomaly, mainly heart disease. Median maternal age was 36 years and 57.1% of mothers were aged 35 or older., Conclusions: This cohort of patients with Down Syndrome provides important information for the optimization of their perinatal management and follow-up.

Background: Persistent neonatal hypoglycemia, owing to the possibility of severe neurodevelopmental consequences, is a leading cause of neonatal care admission. Hyperinsulinemic hypoglycemia is often resistant to dextrose infusion and needs rapid diagnosis and treatment. Several congenital conditions, from single gene defects to genetic syndromes should be considered in the diagnostic approach. Kabuki syndrome type 1 (MIM# 147920) and Kabuki syndrome type 2 (MIM# 300867), can be associated with neonatal hyperinsulinemic hypoglycemia., Patient Presentation: We report a female Italian (Sicilian) child, born preterm at 35 weeks gestation, with persistent hypoglycemia. Peculiar facial dysmorphisms, neonatal hypotonia, and cerebellar vermis hypoplasia raised suspicion of Kabuki syndrome. Hyperinsulinemic hypoglycemia was confirmed with glucagon test and whole-exome sequencing (WES) found a novel heterozygous splicing-site mutation (c.674-1G > A) in KMT2D gene. Hyperinsulinemic hypoglycemia was successfully treated with diazoxide. At 3 months corrected age for prematurity, a mild global neurodevelopmental delay, postnatal weight and occipitofrontal circumference growth failure were reported., Conclusions: Kabuki syndrome should be considered when facing neonatal persistent hypoglycemia. Diazoxide may help to improve hyperinsulinemic hypoglycemia. A multidisciplinary and individualized follow-up should be carried out for early diagnosis and treatment of severe pathological associated conditions.

Objectives: Currarino syndrome (CS) is a congenital disorder that consists of a triad of anomalies: presacral mass, sacral dysgenesis, and anorectal malformations. Few cases of CS with neuroendocrine tumors (NETs) have been reported. In this study, we sought to determine the prevalence and characteristics of NET in patients with CS., Methods: Mayo Clinic electronic medical records were searched for patients with CS. Data on demographics, CS diagnosis, family history, genetic testing, and NET diagnosis were extracted., Results: A total of 26 patients with CS were identified with 3 (11.5%) of them having an additional diagnosis of NET. Three patients had a family history of NET (11.53%), and 7 patients had a family history of CS (26.9%). Of the 3 NET/CS patients, 2 had a confirmed primary NET from the presacral mass, with the third patient demonstrating focal uptake on the somatostatin receptor imaging within the presacral. Two patients received octreotide, followed by peptide receptor radionuclide therapy. The other patient was not treated because of complete resection of presacral mass and is currently undergoing surveillance scans., Conclusions: In our patients with CS, the prevalence of NET is 11.53%. The coexistence of 2 rare conditions, CS and presacral NET, suggests that there may be an etiological connection.

This case report describes a 13-year 10-month-old girl who underwent a deceased-donor split LT for primary diagnosis of biliary atresia at the age of 12 months, who presented with a lower GI bleed. Ultrasound and CT revealed a venous vascular anomaly involving the cecum and ascending colon, with communication of the SMV and pelvic veins consistent with a CEPS. Associated varices were noted in the pelvis along the uterus and urinary bladder. These findings were confirmed by trans-hepatic porto-venography, which was diagnostic and therapeutic as a successful embolization of the CEPS was performed using micro-coils. There were no complications following the procedure and no further GI bleeding occurred, illustrating the efficacy of this treatment option for CEPS. We discuss the literature regarding the presenting complaint of GI bleeding post-LT, CEPS as a rare cause of GI bleeding and its association with PV, and the classification and treatment of CEPS., (© 2020 Wiley Periodicals LLC.)

Objectives: Keratosis pilaris (KP) is the condition of the skin with extensive keratin follicular plugging. It may be associated with the erythema. The upper arm extensor area, shoulders, back of neck and thighs, as well as face and the upper trunk are the areas of presentation. Available medications for KP give only symptomatic relief, while some produce serious side effects. There is no proven universal treatment for the disease that can provide complete recovery. Āyuṛveda management of KP is not yet reported., Case Presentation: A 26-year-old male patient, presented with main complaints started with papular lesions over his right shoulder, chest and upper back along and later with pustular lesions in the past 2 weeks. The condition was associated with redness, mild swelling and itching. The case was diagnosed as Keratosis pilaris based on its presentation, site, and pathogenesis. Also by analyzing the extent of vitiation of doṣas (morbidities), the Vata kapha pitta hara line of treatment was adopted, which was accomplished in two phases i. e. Śodhana Cikitsa and Śamana Cikitsa., Conclusion: Both internal and external treatments along with diet restrictions were found effective in arresting the pathogenesis and recovery in a short period. All the symptoms associated with the condition were completely cured with no signs of re-occurrence., (© 2020 Walter de Gruyter GmbH, Berlin/Boston.)

Objective: Characterize patients with complete tracheal rings and tracheoesophageal fistula (TEF) and summarize management options., Methods: A systematic review of patients under 18 years of age with complete tracheal rings and TEF was conducted. Authors were contacted for additional patient information and new cases were added. Patients with iatrogenic TEF and tracheal stenosis due to other causes were excluded., Results: Sixteen patients with a median (IQR) follow-up of 10 months (3-12 months) were identified. All had a distal TEF with complete tracheal rings distal to the TEF. There were 10 (63%) type C esophageal atresia + TEF (EA/TEF), and 1 (6%) type D (5 missing data). Median (IQR) airway diameter was 2 mm (1.5-2.2 mm). Complete tracheal rings were diagnosed prior to TEF repair in 5 (31.3%) patients, after ≥1 failed extubation in 3 (12.5%) patients, and intra-operatively during respiratory distress in 1 patient. Ten patients (62.5%) were intubated with an endotracheal tube and one with a 6 Fr flexible aortic canula (5 missing data). Four patients with an endotracheal tube for TEF repair developed ventilatory problems. Complete tracheal rings were repaired in 9 (56%) patients (8 slide tracheoplasty, 1 pericardial patch) and followed conservatively in 3 (19%). One patient required tracheotomy. Four patients died., Conclusions: Complete tracheal rings with concurrent TEF is a rare entity that pose challenges for ventilatory management during operative repair. Bronchoscopy prior to TEF repair is critical to allow for proper preoperative planning., Competing Interests: Declaration of competing interest None of the authors have any conflicts of interest to declare., (Crown Copyright © 2020.

Cornelia de Lange syndrome (CdLS) is a severe genetic disorder characterised by multisystemic malformations. CdLS is due to pathogenetic variants in NIPBL , SMC1A , SMC3 , RAD21 and HDAC8 genes which belong to the cohesin pathway. Cohesin plays a pivotal role in chromatid cohesion, gene expression, and DNA repair. In this review, we will discuss how perturbations in those biological processes contribute to CdLS phenotype and will emphasise the state-of-art of CdLS therapeutic approaches., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

Rationale: Wiedemann-Steiner syndrome (WDSTS, online mendelian inheritance in man 605130) is a rare autosomal dominant disorder characterized by hypertrichosis cubiti. Here, we report a Chinese boy who do not show the characteristic of hypertrichosis cubiti, and was misdiagnosed as blepharophimosis-ptosis-epicanthus inversus syndrome at first. We found a de novo frameshift mutation (p.Glu390Lysfs*10) in the KMT2A gene, which was not reported before. Our study increases the cohort of Chinese WDSTS patients, and expand the WDSTS phenotypic and variation spectrum., Patient Concerns: The patient demonstrated typical craniofacial features of blepharophimosis-ptosis-epicanthus inversus syndrome, including small palpebral fissures, ptosis, telecanthus, and epicanthus inversus, besides he had congenital heart disease (ventricular septal defects), strabismus, hypotonia, amblyopia, delayed speech and language development, delayed psychomotor development, and amblyopia (HP:0000646) which was not reported before., Diagnosis: FOXL2 gene was cloned and sequenced, however, there was no mutation detected in this patient. The result of Chromosomal microarray analysis was normal. The patient was diagnosed as WDSTS by whole exome sequencing., Interventions: The patient received cardiac surgery, frontalis suspension and regular speech and occupational therapy. He also treated with growth hormone (GH)., Outcomes: The patient's symptoms are improved after cardiac surgery and frontalis suspension, he can express himself well now and had a 10 cm gain in height., Lessons: As the relationship between genotype and phenotype becomes more and more clear, WES is incredibly powerful tool to diagnose the disease of WDSTS.

Rationale: This case report expands the mutation and phenotypic spectra of Beaulieu-Boycott-Innes syndrome (BBIS), and will be valuable for mutation-based pre- and post-natal screening of BBIS when conducting a genetic diagnosis., Patient Concerns: A 4-year old boy from Guilin City, Guangxi Zhuang Autonomous Region, China, was referred to our clinic for clarification of his diagnosis because he showed moderate intellectual disability., Diagnosis: Two novel compound heterozygous mutations of THOC6, c.664T>C (p.Trp222Arg) and c.945+1 G>A were identified in this patient by whole exome sequencing. The two mutations were evaluated as pathogenic and likely pathogenic respectively according to the American College of Medical Genetics guidelines. This is the first case displaying the BBIS phenotype reported in the Chinese population. These two mutations have not been reported previously., Interventions: Symptomatic treatment and rehabilitation training for patients., Outcomes: The genetic cause of the disease was identified. The family received scientific genetic counseling., Lessons: BBIS is a rare syndromic autosomal recessive disease with intellectual disability and it is normally difficult for clinicians to recognize it. Whole exome sequencing is an efficient way to identify the gene which causes a particular disease in patients.

Noonan syndrome is a pleomorphic genetic disorder, in which a high percentage of affected individuals have cardiovascular involvement, most prevalently various forms of congenital heart disease (i.e., pulmonary valve stenosis, septal defects, left-sided lesions, and complex forms with multiple anomalies). Care includes attentiveness to several comorbidities, some directly impacting cardiac management (bleeding diatheses and lymphatic anomalies). More than 50% of patients with Noonan syndrome harbor PTPN11 pathogenic variation, which results in hyperactivation of RAS/mitogen-activated protein kinase signaling. Several other disease genes with similar biological effects have been uncovered for NS and phenotypically related disorders, collectively called the RASopathies. Molecular diagnosis with gene resequencing panels is now widely available, but phenotype variability and in some cases, subtlety, continues to make identification of Noonan syndrome difficult. Until genetic testing becomes universal for patients with congenital heart disease, alertness to Noonan syndrome's broad clinical presentations remains crucial. Genotype-phenotype associations for Noonan syndrome enable better prognostication for affected patients when a molecular diagnosis is established. We still lack Noonan syndrome-specific treatment; however, newly developed anticancer RAS pathway inhibitors could fill that gap if safety and efficacy can be established for indications such as pulmonary valve stenosis., (© 2020 Wiley Periodicals, Inc.)

Spondylothoracic dysostosis is a rare congenital disorder characterised by multiple vertebral malformations, shortening of the spine and fusion of the ribs at the costovertebral junction. These abnormalities create anaesthetic challenges due to difficult airway, severe restrictive lung disease and spine deformity necessitating a multidisciplinary approach and careful perioperative planning. We present the perianaesthetic management of a parturient with spondylothoracic dysostosis who successfully underwent preterm caesarean delivery under general anaesthesia with awake videolaryngoscopy-assisted tracheal intubation., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2020.

Joubert syndrome (JS) is a recessive neurodevelopmental disorder defined by a characteristic cerebellar and brainstem malformation recognizable on axial brain magnetic resonance imaging as the "Molar Tooth Sign". Although defined by the neurological features, JS is associated with clinical features affecting many other organ systems, particularly progressive involvement of the retina, kidney, and liver. JS is a rare condition; therefore, many affected individuals may not have easy access to subspecialty providers familiar with JS (e.g., geneticists, neurologists, developmental pediatricians, ophthalmologists, nephrologists, hepatologists, psychiatrists, therapists, and educators). Expert recommendations can enable practitioners of all types to provide quality care to individuals with JS and know when to refer for subspecialty care. This need will only increase as precision treatments targeting specific genetic causes of JS emerge. The goal of these recommendations is to provide a resource for general practitioners, subspecialists, and families to maximize the health of individuals with JS throughout the lifespan., (© 2019 Wiley Periodicals, Inc.)

Lateral meningocele syndrome (LMS), a genetic disorder characterized by meningoceles and skeletal abnormalities, is associated with NOTCH3 mutations. We created a mouse model of LMS (Notch3 tm1.1Ecan ) by introducing a tandem termination codon in the Notch3 locus upstream of the proline (P), glutamic acid (E), serine (S) and threonine (T) domain. Microcomputed tomography demonstrated that Notch3 tm1.1Ecan mice exhibit osteopenia. The cancellous bone osteopenia was no longer observed after the intraperitoneal administration of antibodies directed to the negative regulatory region (NRR) of Notch3. The anti-Notch3 NRR antibody suppressed the expression of Hes1, Hey1, and Hey2 (Notch target genes), and decreased Tnfsf11 (receptor activator of NF Kappa B ligand) messenger RNA in Notch3 tm1.1Ecan osteoblast (OB) cultures. Bone marrow-derived macrophages (BMMs) from Notch3 tm1.1Ecan mutants exhibited enhanced osteoclastogenesis in culture, and this was increased in cocultures with Notch3 tm1.1Ecan OB. Osteoclastogenesis was suppressed by anti-Notch3 NRR antibodies in Notch3 tm1.1Ecan OB/BMM cocultures. In conclusion, the cancellous bone osteopenia of Notch3 tm1.1Ecan mutants is reversed by anti-Notch3 NRR antibodies., (© 2019 Wiley Periodicals, Inc.)

Introduction: Polyhandicap is defined as the combination of severe mental impairment and severe motor deficit resulting in reduced mobility and an extreme reduction in autonomy. Over the last 20years, care management for these patients has become more structured, however, their care pathway is not always optimal., Objective: To describe/compare the health characteristics, treatment and history of the care pathways of subjects who received care before and after 1990., Method: Multicentre cross-sectional study, population studied: patients with polyhandicap: (i) causal brain damage<3years, (ii) severe mental impairment, (iii) motor disability, (iv) reduced mobility, (v) extreme restriction of autonomy., Data Collected: clinical and medical, care procedures, treatments, history of care pathways., Results: Patients are divided into 2 groups: 545 patients who received care after 1990 and 330 before 1990. Older patients present more recurrent urinary infections, slow transit, behavioural disorders and pain, and are prescribed a greater number of drugs. For those who received care before 1990, the age of admission to an establishment is lower, with one-third receiving a consultation dedicated to the transition from paediatric to adult teams., Discussion/conclusion: The care sector for patients with polyhandicap makes it possible to meet their needs throughout their lives, however, there is still progress to be made in terms of formalisation and of coordinating the care pathway in order to facilitate the transition from paediatric to adult services/establishments., (Copyright © 2019 Elsevier Masson SAS.

Sakoda complex is a rare but distinct combination of birth defects consisting of a basal cephalocele, agenesis of the corpus callosum, and midline cleft lip/palate. It has been reported in association with ophthalmologic abnormalities, cognitive deficits and severe epilepsy. Here we describe both prenatal and postnatal MRI findings of a classic case of Sakoda complex in a child with characteristic findings on fetal MRI; prenatal findings have not been described in the literature. Diagnosis of this entity has important implications for prenatal counseling and perinatal management, as is demonstrated in this case.

A 19-year-old female with a learning difficulty, ataxia, and nystagmus was referred to our clinic with advanced chronic kidney disease. Her renal biopsy revealed features of nephronophthisis (NPHP). Magnetic resonance imaging of the brain showed "molar tooth sign." The clinical picture was consistent with Joubert syndrome (JS). Two of her siblings were subsequently found to have a similar condition. Genomic material from the patient, her twin sister, and later on from parents was analyzed for deletion/duplication mutations in the NPHP1 gene using multiplex ligation-dependent probe amplification. No genetic defect was discerned. However, applying the emerging "Next-Generation Sequencing (NGS)" method, we identified a novel c.5704G>T mutation in exon 41 of the CEP290 gene on chromosome 12q21. The identification of this novel mutation, that is, highly likely to be pathogenic was compatible with the diagnosis of JS. This mutation may be included in screening and diagnostic panel. NGS provides an excellent screening method for genetic testing.

Mutations in the CHRNG gene cause autosomal recessive multiple pterygium syndrome (MPS). Herein we present a long-term follow-up of seven patients with CHRNG-related nonlethal MPS and we compare them with the 57 previously published patients. The objective is defining not only the clinical, histopathological, and molecular genetic characteristics, but also the type and degree of muscle involvement on whole-body magnetic resonance imaging (WBMRI). CHRNG mutations lead to a distinctive phenotype characterized by multiple congenital contractures, pterygium, and facial dysmorphism, with a stable clinical course over the years. Postnatal abnormalities at the neuromuscular junction were observed in the muscle biopsy of these patients. WBMRI showed distinctive features different from other arthrogryposis multiple congenita. A marked muscle bulk reduction is the predominant finding, mostly affecting the spinal erector muscles and gluteus maximus. Fatty infiltration was only observed in deep paravertebral muscles and distal lower limbs. Mutations in CHRNG are mainly located at the extracellular domain of the protein. Our study contributes to further define the phenotypic spectrum of CHRNG-related nonlethal MPS, including muscle imaging features, which may be useful in distinguishing it from other diffuse arthrogryposis entities., (© 2019 Wiley Periodicals, Inc.)

Papillon-Léage-Psaume Syndrome, also known as oral-facial-digital syndrome (OFDS) type I, describes a group of neurodevelopmental disorders that are characterized by anomalies of the oral cavity, facial features, and the digits. Central nervous system (CNS) anomalies and visceral organ abnormalities such as kidney, pancreas, and ovarian cysts can also be seen in these patients. Among 13 potential types, female-inherited OFDS type I is the most common and it has been reported to be lethal in males. After the identification of the genetic relation of OFDS in 2001, it is now known that, except X-linked OFDS Type I and VIII, generally all types of OFDSs are autosomal recessive. The dentist's knowledge about the syndrome can reduce the development of physical and dental anomalies by facilitating early diagnosis. This article presents a patient with Papillon-Léage-Psaume Syndrome (Oral-Facial-Digital Syndrome Type I)., Competing Interests: None

Objective: We aimed to evaluate the use of miR-200b as a prenatal transplacental therapy in the nitrofen rat model of abnormal lung development and congenital diaphragmatic hernia (CDH)., Background: Pulmonary hypoplasia (PH) and pulmonary hypertension determine mortality and morbidity in CDH babies. There is no safe medical prenatal treatment available. We previously discovered that higher miR-200b is associated with better survival in CDH babies. Here, we investigate the role of miR-200b in the nitrofen rat model of PH and CDH and evaluate its use as an in vivo prenatal therapy., Methods: We profiled miR-200b expression during nitrofen-induced PH using RT-qPCR and in situ hybridization in the nitrofen rat model of PH and CDH. The effects of nitrofen on downstream miR-200b targets were studied in bronchial lung epithelial cells using a SMAD luciferase assay, Western blotting and Immunohistochemistry. We evaluated miR-200b as a lung growth promoting therapy ex vivo and in vivo using lung explant culture and transplacental prenatal therapy in the nitrofen rat model., Results: We show that late lung hypoplasia in CDH is associated with (compensatory) upregulation of miR-200b in less hypoplastic lungs. Increasing miR-200b abundance with mimics early after nitrofen treatment decreases SMAD-driven TGF-β signaling and rescues lung hypoplasia both in vitro and in vivo. Also, prenatal miR-200b therapy decreases the observed incidence of CDH., Conclusions: Our data indicate that miR-200b improves PH and decreases the incidence of CDH. Future studies will further exploit this newly discovered prenatal therapy for lung hypoplasia and CDH.

The respiratory difficulties experienced by infants with omphalocele are being appreciated with greater frequency. These problems represent self-limited difficulties related to omphalocele closure or are the result of severe pulmonary disease including pulmonary hypoplasia and pulmonary hypertension. Infants with giant omphalocele represent a unique group that may experience increased respiratory morbidity which may lead to chronic respiratory problems extending into childhood and adolescence. Importantly, respiratory insufficiency at birth is an independent predictor of mortality for patients with omphalocele. In this review, we will provide a summary of the respiratory difficulties experienced by patients with omphalocele as well as insight into management and surveillance., (Copyright © 2019 Elsevier Inc.

Purpose: Infra-vesical obstruction is uncommon in infants and generally due to urethral valves. Congenital urethral strictures (CUS), instead, defined as a concentric narrowing of the urethral lumen, are exceedingly rare in infants., Materials and Methods: We reviewed our experience with 7 patients treated at our institution for CUS

A 24-year-old woman presented to neurosurgical consultation for chronic back pain. The patient was long term in wheelchair for vertebral deformity. She was the third child of first-degree consanguineous parents. The 2 older brothers had also vertebral malformations. The radiological images showed butterfly vertebra, vertebral fusion, hemivertebrae, scoliosis, and rib malformation. The patient was in follow-up for restrictive lung disease. Motor evoked potentials and lower limb electromyography were normal. We recommended conservative treatment for the back pain with antalgic and physical therapy. Diagnosis of spondylocostal dysostosis, or Jarcho-Levin syndrome, was made based on radiological features. Radiological mages are pathognomonic. Spondylocostal dysostosis is a rare hereditary disorder associated with multiple vertebral and rib anomalies. The entity is distinct from spondylothoracic dysostosis, which has a higher mortality due to respiratory complications. The patient was not compliant for genetic familiar counseling. At 12-year follow-up, the patient was in periodic respiratory and motor rehabilitation therapy., (Copyright © 2018 Elsevier Inc. All rights reserved.)

Purpose: Pulmonary hypoplasia secondary to congenital diaphragmatic hernia (CDH) is characterized by impaired epithelial homeostasis. Recently, amniotic fluid stem cells (AFSCs) have been shown to promote growth in hypoplastic lungs of rat fetuses with CDH. Herein, we investigated whether CDH hypoplastic lungs mount an endoplasmic reticulum (ER) stress response and whether AFSCs could re-establish pulmonary epithelial homeostasis., Methods: Primary epithelial cells were isolated from fetal rat lungs at E14.5 from control and nitrofen-exposed dams at E9.5. Nitrofen-exposed epithelial cells were grown in medium alone or co-cultured with AFSCs. Epithelial cell cultures were compared for apoptosis (TUNEL), cytotoxicity (LIVE/DEAD assay), proliferation (5'EdU), and ER stress (CHOP, Bcl-2) using one-way ANOVA (Dunn's post-test)., Results: Compared to control, nitrofen-exposed epithelial cells had increased cytotoxicity and apoptosis, reduced proliferation, and activated ER stress. AFSCs restored apoptosis, proliferation, and ER stress back to control levels, and significantly reduced cytotoxicity., Conclusions: This study shows for the first time that ER stress-induced apoptosis is activated in the pulmonary epithelium of hypoplastic lungs from fetuses with CDH. AFSC treatment restores epithelial cellular homeostasis by attenuating the ER stress response and apoptosis, by increasing proliferation and migration ability, and by reducing cytotoxicity.

Perinatology is a dynamically developing field of medicine. The progress of technology in recent decades has made it possible to recognize birth defects very early, including those which are lethal or genetically determined. In many clinical situations, it is no longer possible to work alone to reach a definitive diagnosis, plan treatment or predict the clinical course of the affected fetus/newborn. There is a need for teamwork, which ensures the proper, early care starting in the fetal period, not only in the delivery room or NICU. This paper discusses the ethical foundations of creating interdisciplinary teams, taking as an example the Interdisciplinary Team for Fetal Malformation at the Institute of Mother and Child in Warsaw, which has been active for 25 years, and presents how it works in practice. On the basis of the clinical cases that are examined, practical guidelines were formulated for both the work of medical teams and the way parents are informed about the clinical situation of their child and about sharing the care after the birth of the child. A document was also proposed with information on prenatal diagnosis, decisions made by the interdisciplinary team regarding the mother and child, as well as the conclusions resulting from discussions with parents.

Objectives: The aim of this work was to describe treatment response and outcome data for preterm infants with pulmonary hypoplasia treated with inhaled nitric oxide (iNO). We hypothesised that an acute oxygenation response to iNO would be associated with survival., Design: A retrospective observational study design was used to identify cases of pulmonary hypoplasia in preterm infants <34 weeks' gestation reported to the European iNO Registry. Demographic and clinical data were collected including oxygenation and echocardiographic parameters. The primary outcome was acute oxygenation response defined as a reduction in fractional inspired oxygen of >0.15. Outcome data included chronic lung disease (CLD) and death., Results: Seventy-two infants with pulmonary hypoplasia were treated with iNO during a 10-year period (2007-2016). In total, 30/69 (43%) of the infants showed a significant improvement in oxygenation and were categorised as "responders." Thirty-one treated infants died, and 19 survivors developed CLD. Although there were no differences in demographics and baseline cardiorespiratory parameters between responders and non-responders, an acute response was significantly associated with survival. Neither pulmonary hypertension nor PPHN (persistent pulmonary hypertension of the newborn) physiology predicted the acute response to iNO or survival., Conclusion: Although the acute oxygenation response to iNO therapy in pulmonary hypoplasia is comparable to other respiratory disorders in preterm infants, mortality in this group remains very high. An acute response is associated with survival and suggests that a short therapeutic trial of iNO therapy is warranted in this population. This study underscores the value of registries in evaluating therapies for rare neonatal disorders, although their limitations must be recognised., (© 2019 S. Karger AG, Basel.)

Aim:  The study aimed to compare outcomes and intestinal morbidity among complicated gastroschisis, isolated gastroschisis, and intestinal atresia., Methods:  In this retrospective observational single institution study, outcomes and intestinal morbidity were compared among gastroschisis complicated by intestinal atresia or perinatal bowel perforation, isolated gastroschisis, and isolated intestinal atresia. We included two cohorts; the first cohort included 68 consecutive patients with complicated gastroschisis ( n  = 9), isolated gastroschisis ( n  = 34), and intestinal atresia ( n  = 25) managed in our center. The second cohort included 20 patients (12 referred) with intestinal failure due to these underlying etiologies managed by our intestinal rehabilitation team., Results:  Patients with complicated gastroschisis had a significantly longer need for mechanical ventilation, primary hospital stay, and duration of parenteral nutrition (PN) and developed intestinal failure more often compared with other groups ( p  < 0.05 for all). Reoperations for surgical complications were also more frequent in patients with complicated gastroschisis ( p  < 0.05). Among those, who developed intestinal failure, autologous intestinal reconstruction (AIR) surgery was performed in 11 patients with comparable frequency in all groups. Repeated AIR surgery for bowel re-dilatation was required in 3/3 patients with complicated gastroschisis and 0/8 with isolated gastroschisis or intestinal atresia ( p  = 0.004)., Conclusion:  Complicated gastroschisis is associated with markedly increased intestinal morbidity, reflected by prolonged duration of PN, more frequent reoperations for intestinal complications, and bowel re-dilatation after AIR surgery, when compared with patients with isolated gastroschisis or intestinal atresia., Competing Interests: None., (Georg Thieme Verlag KG Stuttgart · New York.)

Nablus syndrome was first described by the late Ahmad Teebi in 2000, and 13 individuals have been reported to date. Nablus syndrome can be clinically diagnosed based on striking facial features, including tight glistening skin with reduced facial expression, blepharophimosis, telecanthus, bulky nasal tip, abnormal external ear architecture, upswept frontal hairline, and sparse eyebrows. However, the precise genetic etiology for this rare condition remains elusive. Comparative microarray analyses of individuals with Nablus syndrome (including two mother-son pairs) reveal an overlapping 8q22.1 microdeletion, with a minimal critical region of 1.84 Mb (94.43-96.27 Mb). Whereas this deletion is present in all affected individuals, 13 individuals without Nablus syndrome (including two mother-child pairs) also have the 8q22.1 microdeletion that partially or fully overlaps the minimal critical region. Thus, the 8q22.1 microdeletion is necessary but not sufficient to cause the clinical features characteristic of Nablus syndrome. We discuss possible explanations for Nablus syndrome, including one-locus, two-locus, epigenetic, and environmental mechanisms. We performed exome sequencing for five individuals with Nablus syndrome. Although we failed to identify any deleterious rare coding variants in the critical region that were shared between individuals, we did identify one common SNP in an intronic region that was shared. Clearly, unraveling the genetic mechanism(s) of Nablus syndrome will require additional investigation, including genomic and RNA sequencing of a larger cohort of affected individuals. If successful, it will provide important insights into fundamental concepts such as variable expressivity, incomplete penetrance, and complex disease relevant to both Mendelian and non-Mendelian disorders., (© 2018 Wiley Periodicals, Inc.)
