Project description:Objective: The aim of the present study is to explore the clinical and genetic characteristics of 3p deletion syndrome to improve clinicians' understanding of the disease. Methods: The clinical manifestations, process of diagnosis and treatment, and genetic characteristics of an individual case of 3p deletion syndrome were analyzed. CNKI, Wanfang Data, and the Biomedical Literature Database (PubMed) were searched. The search time limit, using "3p deletion syndrome" and "BRPF1" as keywords, was from the creation of the database up to June 2020. Related data were reviewed. Results: The proband was a male child with general developmental and intellectual disabilities, special facial features and congenital heart disease. The child was the parents' first pregnancy and first born. Gene microarray analysis showed a 10.095 Mb deletion in the 3p26.3-p25.3 region, resulting in a heterozygous mutation of the BRPF1 gene; thus, the patient was diagnosed with 3p deletion syndrome. At the time of diagnosis, the child was 1 year of age and was responding to comprehensive rehabilitation training. A total of 29 well-documented cases were found in the literature, of which 19 cases had an onset within 1 year of birth, and mainly manifested with mental and motor development disabilities and abnormal facial features, with different gene deletions, depending on the size and location of the 3p deletion. Conclusion: The genetic test results of the child in this study indicated a heterozygous deletion of the BRPF1 gene on the short arm of chromosome 3, which was a unique feature of this study, since it was rarely mentioned in other reports of 3p deletion syndrome. The clinical phenotype of this syndrome is complex as it can include intellectual and motor development backwardness, low muscle tone, certain abnormal facial features (low hairline, bilateral ptosis, widely spaced eyes, a forward nose, left ear auricle deformity, a high-arched palate, a small jaw), and the deformation of systems such as the gastrointestinal tract and the urinary tract malformation or symptoms of epilepsy. As clinical manifestations can be relatively mild, the syndrome is easy to miss or misdiagnose. Clinical workers need to be aware of this disease when they find that children have special features, such as stunted growth, low muscle tone or ptosis, and it needs to be diagnosed through genetic testing. Most children are able to develop certain social skills after rehabilitation treatment.

Project description:BackgroundBerry syndrome, a rare combination of cardiac anomalies, consists of aortopulmonary window (APW); aortic origin of the right pulmonary artery; interrupted aortic arch (IAA) or hypoplastic aortic arch or coarctation of the aorta; and an intact ventricular septum. There is lack of review articles that elucidate the clinical features, diagnosis, treatment, and outcomes of Berry syndrome. This publication systematically reviews the 89 cases published since 1982 on Berry syndrome.Case presentationA 38-year-old woman presented with a loud murmur and cyanosis. Transthoracic echocardiography demonstrated a severely dilated aorta and main pulmonary artery with a large intervening defect. Distal to the APW, the ascending aorta gave rise to the right pulmonary artery. Additionally, a type A IAA, an intact ventricular septum, and a large patent ductus arteriosus were revealed. Computed tomography angiography with 3-dimensional reconstruction confirmed above findings. This is the first report of a patient of this age with Berry syndrome who did not undergo surgery.ConclusionsBerry syndrome is a rare but well-identified and surgically correctable anomaly. Patients with Berry syndrome should be followed up for longer periods to better characterize long-term outcomes.

Project description:Lemierre's syndrome has been shown to be increasing in incidence in the past 20 years with one popular suggesting that said rise occurred from less aggressive antibacterial coverage. We report a case of Lemierre's syndrome and also reviewed the 15 most recent case reports. A previously healthy 25 year old male who initially developed sore throat and flu-like symptoms, was prescribed antibacterials as an outpatient but was hospitalized for worsening symptoms. He was later diagnosed with Lemierre's syndrome and improved clinically with IV antimicrobials alone. From our concise literature review, we determined that a decrease in antibiotic prescriptions may not fully explain why the incidence of Lemierre's has been increasing. Thus, future research should be focused in evaluating possible worsening susceptibilities to antibiotics and improvements on detection. We also advise physicians to be aware of the signs and symptoms of this rare but potentially fatal condition as well as the available detection methods and treatment.

Project description:Netherton syndrome (NS) is a rare autosomal recessive disorder characterized by a triad of congenital ichthyosiform erythroderma (CIE) or ichthyosis linearis circumflexa (ILC), hair shaft abnormalities, and atopic diathesis (elevated serum IgE ). We report a case of a two-year-old boy presented with intractable pruritus, scaling, dry skin and generalized eczematous lesions resistant to atopic dermatitis therapy. Netherton syndrome misdiagnosed as atopic dermatitis due to the presence of eczematous skin lesions and allergic problems. The family counseled about the diagnosis and need of genetic testing for confirmation, but they refused for genetic testing. The patient got treatment with topical corticosteroids and skin moisturizers. There is no cure or satisfactory treatment currently available for NS. Further understanding of the underlying pathophysiology of integumentary changes will lead to more effective treatment. Netherton syndrome should be in the differential diagnosis when characteristic skin manifestation of CIE or ILC, and elevated serum IgE present.

Project description:The study's purpose is to investigate the clinical characteristics and research progress of PURA syndrome. It will also provide new ideas and methods for the diagnosis of neonatal hypotonia etiology. A case of PURA syndrome admitted to Shenzhen Hospital of Peking University was analyzed retrospectively. The keywords "PURA", "PUR?", "PURA syndrome", and "5q31" were used to search the Chinese periodical full-text database and Wanfang database. The keywords "PURA", "PUR?", "Pur-alpha", "PURA syndrome", and "5q31" were used to search the biomedical literature database (PubMed). The Web of Science database and Proquest database were used to find works of literature from the establishment of the database to November 10, 2019. By analyzing the 72 cases of PURA syndrome reported in ten Chinese and international studies, it was found that 57% (21/37) of the patients had a gestational age greater than 41 weeks. Neonatal patients exhibited hypotonia (82%, 59/72), feeding difficulties (97%, 64/66), apnea or primary hypoventilation (57%, 41/72), intrauterine excessive hiccupping (55%, 6/11), and drowsiness (51%, 24/47). After the neonatal period, the pediatric patients demonstrated moderate to severe mental retardation (100%), epilepsy (54%, 29/54), progressive hip dysplasia (17%, 7/42), scoliosis (48%, 11/23), dysphagia and salivation (69%, 25/36), and constipation (60%, 21/35). The clinical manifestations of the present case were consistent with those in the literature reports. It was the first confirmed case at Shenzhen Hospital in the neonatal period and had a de novo mutation. It was difficult to diagnose PURA syndrome in the neonatal period, which might affect multiple systems. In newborns with obvious hypotonia, the evaluation should be expanded to consider other symptoms. Additionally, targeted gene detection should be completed to achieve early diagnosis and intervention, improve the prognosis, and perform genetic counseling.

Project description:"CADASIL" is a genetic microangiopathy with autosomal dominant inheritance. Its epidemiology and physiopathogenesis are poorly specified, but it is proven that this disease is due to a mutation of the NOTCH3 gene resulting in a loss of elasticity of the media of the affected vessels. The clinical expression is variable, dominated by migraine attacks with aura, ischemic vascular accidents and psychiatric disorders, in particular depression. MRI is essential for diagnosis even in the pre-symptomatic phase. It shows signal abnormalities in the basal ganglia and white matter, characteristic especially when located in the anterior part of the temporal lobes. The management of CADASIL is multidisciplinary, psychological for the most part without specificity of a particular treatment.

Project description:PurposePosterior microphthalmia is a sporadic or inherited developmental ocular anomaly that may occur isolated or in association with multiple ocular and systemic anomalies. This report documents a case of posterior microphthalmia with atypical presentation including white dots in the posterior pole in addition to systemic anomalies including facial defect that can represent an underlying genetic mutation.MethodCase report.ResultsA 29-year-old male with high hyperopia and history of bilateral clear lens presented with pigmentary changes and white-yellow dots in the posterior pole in both eyes. Patient had a history of cleft lip repair. A complete ocular evaluation including A/B scan and optical coherence tomography confirmed the diagnosis of posterior microphthalmia with a retinitis pigmentosa like fundus and drusen deposits in the subretinal pigment epithelium.ConclusionThe white-yellow drusenoid deposits in the posterior pole in association with posterior microphthalmia are poorly documented in the literature. Cases of craniofacial developmental defects in association with posterior microphthalmia may represent a genetic defect.

Project description:BACKGROUND:Cenani-Lenz Syndactyly (CLS) syndrome is a rare autosomal recessive disorder characterized by syndactyly and oligodactyly of fingers and toes, disorganization and fusion of metacarpals, metatarsals and phalanges, radioulnar synostosis and mesomelic shortness of the limbs, with lower limbs usually being much less affected than upper limbs. CASE PRESENTATION:we report here two patients, born to consanguineous Sri Lankan parents, present with bilateral postaxial oligodactyly limited to upper limbs. While the proband has no noticeable facial dysmorphism, renal impairments or cognitive impairments, his affected sister displays a few mild facial dysmorphic features. Whole exome sequencing of the proband showed a novel deleterious homozygous mutation (c.1348A?>?G) in the LRP4 gene, resulting in an Ile450-to-Val (I450V) substitution. CONCLUSION:This recessive mutation in LRP4 confirmed the diagnosis of CLS syndrome in two patients present with isolated hand syndactyly. This is the first reported case of CLS syndrome in a family of Sri Lankan origin.

Project description:De Sanctis-Cacchione (DSC) syndrome is one of the rarest, most severe forms of xeroderma pigmentosum (XP). These patients with XP are of short stature, have mental disabilities, and develop progressive neurologic degeneration because of a severe inability to repair damaged DNA. Herein, we will present the case of a 9-year-old boy who had DSC syndrome with microcephaly, severe psychomotor retardation, ataxia, and hearing loss. The cutaneous manifestations included giant squamous cell carcinoma (SCC) that covered the eye, multiple facial SCCs, and pigment changes on sun-exposed areas. In addition, we include a review of reported rare cases and a brief discussion of disease management.
