1/8. Two patients with Kabuki syndrome presenting with endocrine problems.A 4 year-old boy with mental retardation and seizures presented to the pediatric endocrinology clinic because of a history of hypoglycemia; a 16 month-old girl with developmental delay presented with bilateral breast tissue enlargement; in both, a diagnosis of Kabuki syndrome was made because of typical facial features, neurodevelopmental delay and other stigmata consistent with Kabuki syndrome. Kabuki syndrome is a mental retardation-malformation syndrome affecting multiple organ systems with a broad spectrum of abnormalities. The facial features of the syndrome are specific and independent of ethnic origin. In addition to presenting with endocrine problems, the patients reported here exhibit some novel findings such as congenital alopecia areata and hyperpigmented skin lesion. The diagnosis of Kabuki syndrome should be considered in patients with hypoglycemia or premature thelarche when associated with developmental delay and a peculiar facies.- - - - - - - - - - ranking = 1keywords = endocrine (Clic here for more details about this article) |
2/8. Anaesthetic implications of costello syndrome.costello syndrome is a disorder that primarily involves ectodermal tissues and is characterized by mental and growth retardation, distinctive coarse facies, redundant skin (neck, palms and soles), and papillomata (perioral, nasal and anal). Of primary concern to anaesthesiologists are potential airway difficulties related a short neck, macroglossia, hypertrophied tonsillar and supraglottic tissues, laryngeal papillomata and choanal atresia. A significant percentage of patients also have cardiac involvement which may manifest as congenital heart defects, arrhythmias, valvular dysfunction, or hypertrophic cardiomyopathy. central nervous system involvement includes developmental delay and seizure disorders while endocrine abnormalities have been reported including hypothalamic-pituitary dysfunction resulting in hypopituitarism, hypothyroidism, and hypoadrenalism. The authors present a 2-year old child with costello syndrome who required anaesthesia for direct laryngoscopy, rigid bronchoscopy, bilateral pressure equalization tubes and tonsillectomy. The perioperative implications of the syndrome are discussed.- - - - - - - - - - ranking = 0.2keywords = endocrine (Clic here for more details about this article) |
3/8. growth retardation, developmental delay, distinctive face, multiple endocrine abnormalities, and adenylyl cyclase dysfunction: a new syndrome?We report on a 17-year-old male with severe pre- and postnatal growth retardation, craniosynostosis, distinctive facial features, acanthosis nigricans, deafness, mental retardation and progressive multi-organ involvement, particularly of the endocrine system, including hypothyroidism, hypogonadism, transitory hypoparathyroidism, and insulin resistance. In order to find a common mechanism explaining these multiple abnormalities, we searched for a possible defect in the signal transduction pathways from membrane to nucleus involving G-protein coupled receptors (GPCR). Adenylyl cyclase activity was evaluated by assaying c-AMP in the patient's cultured fibroblasts stimulated with several drugs and toxins acting on different effectors upstream of adenylyl cyclase. The preliminary results indicate a reduced cAMP accumulation in the patient, neither caused by constitutive activation of Gi nor inhibition of Gs signaling, and probably resulting from an alteration in the adenylyl cyclase system. The differential diagnosis with syndromes showing common clinical features with our patient is discussed.- - - - - - - - - - ranking = 11.63978310291keywords = multiple endocrine, endocrine (Clic here for more details about this article) |
4/8. Asymmetric crying facies associated with congenital hypoparathyroidism and 22q11 deletion.Asymmetric crying facies is caused by congenital hypoplasia or agenesis of the depressor anguli oris muscle. Associations of this facial defect with major congenital anomalies have been reported, most commonly in the cardiovascular system and less frequently involving the genitourinary, musculoskeletal, cervicofacial, respiratory, and rarely, the endocrine system. CATCH 22 is a medical acronym for cardiac defects, abnormal facies, thymic hypoplasia, cleft palate and hypocalcemia and a variable deletion on chromosome 22q11. The deletion within chromosme region of 22q11 may occur in patients with dysmorphologic and cardiological syndromes: digeorge syndrome, velo-cardiofacial syndrome and conotruncal anomaly face syndrome. We report a newborn infant who had asymmetric crying facies associated with congenital hypoparathyroidism, severe neonatal hypocalcemia and tetralogy of fallot. Genetic confirmation of chromosome 22q11 deletion was made.- - - - - - - - - - ranking = 0.2keywords = endocrine (Clic here for more details about this article) |
5/8. Case report: multiple endocrine neoplasia type 2b misdiagnosed as familial dysautonomia.BACKGROUND: Familial dysautonomia (FD) is a rare autosomal recessive disorder of the peripheral nervous system, affecting exclusively Jewish children of Ashkenazi extraction. The typical clinical features consist of somatic abnormalities: failure to thrive, characteristic facies, excessive sweating, labile blood pressure, recurrent aspiration pneumonias, lack of tears, and diminished and later absent deep tendon reflexes with generalized reduction of pain sensation. Oro-dental features include a lack of tongue fungiform papillae, impairment of taste, oro-dental self-mutilation, dental crowding, excessive plaque and calculus accumulation, salivary over production and low caries experience. CASE REPORT: A child with multiple endocrine neoplasia type 2b (men 2B) received, at the age of 11 months, an incorrect diagnosis of familial dysautonomia (FD). At the age of 6 years, a paediatric dentist experienced with FD noticed a normal number and shape of tongue fungiform papillae, while expecting to find a smooth tongue lacking those structures. The presence of numerous submucosal neuromata initiated a meticulous neurological and endocrine work-up, which established the diagnosis of men 2B. This led to an early detection and appropriate treatment of asymptomatic medullary thyroid carcinoma (MTC).- - - - - - - - - - ranking = 19.732144751953keywords = multiple endocrine, multiple endocrine neoplasia, endocrine neoplasia, endocrine, neoplasia (Clic here for more details about this article) |
6/8. Multiple endocrine neoplasia syndrome, type III: review and case report.Successful treatment of the multiple endocrine neoplasia type III (men III) syndrome requires early diagnosis. It is highly possible that the patient's dentist may be the first practitioner with the opportunity to diagnose this potentially fatal syndrome. Additionally, patients with this syndrome having a pheochromocytoma and needing invasive dental treatment pose a life-threatening dental management risk. This article presents a review of the men II syndrome and a case report on the surgical management of a men III patient with a pheochromocytoma.- - - - - - - - - - ranking = 6.0445573738466keywords = multiple endocrine, multiple endocrine neoplasia, endocrine neoplasia, endocrine, neoplasia (Clic here for more details about this article) |
7/8. CNS malformation in a child with Kabuki (Niikawa-Kuroki) syndrome: report and review.Kabuki (Niikawa-Kuroki) syndrome (KS) comprises characteristic facial changes, developmental delay, skeletal anomalies, mental retardation, and abnormal dermatoglyphics. We report on a 5-year-old Caucasian boy with KS who required surgery for a giant left temporoparietal subarachnoid cyst at age 5 1/2 years. review of the 143 published cases shows that while malformations may be found in the endocrine, cardiac, genitourinary and skeletal systems, this is the first case of Kabuki syndrome with a major central nervous system malformation.- - - - - - - - - - ranking = 0.2keywords = endocrine (Clic here for more details about this article) |
8/8. An adult with 49,XYYYY karyotype: case report and endocrine studies.Sex chromosome abnormalities, such as 47,XXX, 47,XXY, 47,XYY, and 45,X, are relatively common and occur in approximately 1 of 400 births. Sex chromosome tetrasomy and pentasomy are much rarer events. The somatic and developmental consequences of supernumerary sex chromosomes have not been studied adequately. This is especially true of individuals with only supernumerary Y chromosomes. Based on available case reports, the effects of extra Y chromosomes appear not as severe as those of supernumerary X chromosomes. Only two case reports of nonmosaic tetrasomy of the y chromosome have been published. We evaluated a 30-year-old man with a 49,XYYYY karyotype and assessed his severe physical and mental handicaps (particularly the endocrine abnormalities) and attempted to clarify the effects of extra Y chromosomes on growth, development, and behavior.- - - - - - - - - - ranking = 1keywords = endocrine (Clic here for more details about this article) |
