ABSTRACT

Abstract Objective: To estimate the prevalence and presentation of bladder, bowel, and combined bladder and bowel symptoms experienced by children with osteogenesis imperfecta and to describe the socio-demographic and clinical profile of these children. Method: A descriptive study was conducted with a convenience sample of parent-child pairs of toilet-trained children aged from 3 to 18 years. Pairs were interviewed using three tools: (1) Socio-Demographic and Clinical Questionnaire; (2) Dysfunctional Voiding Scoring System; (3) Rome III Criteria along with the Bristol Stool Scale. Data were stratified by socio-demographic and clinical variables and analyzed using descriptive statistics. Results: Thirty-one parent-child pairs participated in the study; 38.7% (n = 12) children reported bowel symptoms, 19.4% (n = 6) reported a combination of bladder issues (such as holding maneuvers and urgency) and bowel symptoms (such as hard or painful bowel movements and large diameter stools). There were no reports of isolated bladder issues. Among the child participants, 16 (51.7%) identified as female and 20 (64.5%) were 5-14 years old. The most prevalent type of osteogenesis imperfecta was type III (n = 12; 38.7%) and eight (25.8%) children reported using a wheelchair. Conclusion: This is the first study to examine the prevalence and presentation of bladder, bowel, and combined bladder and bowel symptoms in children with osteogenesis imperfecta, offering a preliminary socio-demographic and clinical profile of these children. This research is an important step toward effective screening, detection, and access to care and treatment, especially for clinicians working with this group of very fragile patients.


Resumo Objetivo: Estimar a prevalência e a apresentação de sintomas urinários, intestinais e urinários e intestinais combinados sofridos por crianças com osteogênese imperfeita e descrever o perfil sociodemográfico e clínico dessas crianças. Método: Foi realizado um estudo descritivo com uma amostra de conveniência de pares de pais-filhos de crianças treinadas para usar o banheiro com idades entre três e 18 anos. Os pares foram entrevistados utilizando três instrumentos: 1) o Questionário Sociodemográfico e Clínico; 2) o questionário Dysfunctional Voiding Scoring System; 3) os Critérios de Roma III juntamente com a Escala de Bristol para Consistência de Fezes. Os dados foram estratificados por variáveis sociodemográficas e clínicas e analisados com estatísticas descritivas. Resultados: Participaram do estudo 31 pares de pais-filhos, 38,7% (n = 12) crianças relataram sintomas intestinais, 19,4% (n = 6) relataram uma combinação de problemas urinários (como segurar e urgência miccional) e sintomas intestinais (como fezes duras ou evacuações dolorosas e fezes de grande dimensão). Não houve relatos de problemas urinários isolados. Entre as crianças, 16 (51,7%) eram meninas e 20 (64,5%) tinham entre 5 e 14 anos. O tipo mais prevalente de osteogênese imperfeita foi o III (n = 12; 38,7%) e 8 (25,8%) crianças relataram usar cadeira de rodas. Conclusão: Este é o primeiro estudo a examinar a prevalência e a apresentação de sintomas urinários, intestinais e urinários e intestinais combinados em crianças com osteogênese imperfeita e que mostra um perfil sociodemográfico e clínico preliminar dessas crianças. Nossa pesquisa é um passo importante com relação ao efetivo rastreamento, detecção e acesso ao cuidado e tratamento, principalmente para os profissionais de saúde que trabalham com esse grupo de pacientes tão frágeis.

ABSTRACT

Resumen Introducción: La osteogénesis imperfecta (OI) es el trastorno óseo hereditario más común, con una incidencia de 1 en 10,000 a 25,000 nacimientos. Este trastorno está causado principalmente por mutaciones de los genes que codifican las cadenas del colágeno tipo I. En la mayoría de los casos, se presenta un patrón de herencia autosómico dominante. La OI se caracteriza principalmente por un aumento en la fragilidad ósea que da lugar a fracturas frecuentes que producen dolor, deformidad y discapacidad asociada con otras alteraciones. El objetivo del estudio fue exponer las características clínicas y epidemiológicas de una serie de pacientes pediátricos con diagnóstico de OI evaluados en la Universidad de Los Andes. Métodos: El presente trabajo consiste en el análisis de una serie de 37 casos pediátricos con diagnóstico de OI, de acuerdo a la clasificación clínica y radiológica de Sillence, evaluados en la consulta de la Unidad de Genética Médica de la Universidad de Los Andes, entre enero de 2006 y diciembre de 2018. Resultados: La OI tipo I fue la de presentación más frecuente, con 31 pacientes (83.78%). El fémur fue el hueso más afectado de manera conjunta. Las escleras azules fueron el hallazgo adicional más frecuente, en 32 pacientes (86.49%). Conclusiones: La OI representa el principal motivo de consulta por alteraciones en el sistema esquelético en la Unidad de Genética Médica de la Universidad de Los Andes. Ante la amplia forma clínica de presentación, la evaluación debe ser individual e interdisciplinaria. A través de un estudio más profundo se podrá brindar el oportuno asesoramiento genético familiar.


Abstract Background: Osteogenesis imperfecta (OI) is the most common hereditary bone disorder with an incidence of one in 10,000-25,000 births. It is caused mainly by mutations in the genes that code for Type I collagen chains. In most cases, it shows an autosomal dominant inheritance pattern. OI is characterized by an increase in bone fragility that leads to frequent fractures, which cause pain, deformity and disability associated with other alterations. The objective of this study was to present the clinical and epidemiological characteristics of a series of pediatric patients diagnosed with OI evaluated at the University of Los Andes. Methods: A series of 37 pediatric cases with diagnosis of OI according to the clinical and radiological classification of sillence is analyzed, which were evaluated in the medical genetics unit of the University of Los Andes consultation between January 2006 and December 2018. Results: Type I was the most frequent OI type, with 31 patients (83.78%). Additionally, the femur was the most affected bone. Blue scleras were the most frequent additional finding in 32 patients (86.49%). Conclusions: OI represents the main reason for consultation of alterations in the skeletal system in the medical genetics unit of the University of Los Andes. Given the broad clinical presentation, the evaluation must be individual and interdisciplinary. Further study will provide timely family genetic counseling.

ABSTRACT

Fanconi-Bickel syndrome is an extremely rare hereditary metabolic disease, characterized by hepatomegaly due to glycogen storage, refractory hypophosphatemic rickets, marked growth retardation and proximal renal tubular acidosis. Recurrent bone fractures are one of the hallmark findings. It is a single gene disorder; the responsible gene belongs to the facilitative glucose transporters 2 (GLUT2) family gene or (SLC2A2) mapped to the q26.1-26.3 locus on chromosome 3, and encodes the GLUT protein 2. This protein is expressed in pancreatic ί-cells, hepatocytes, renal tubules, and intestinal mucosa. Several mutations in the GLUT2 gene have been reported in different ethnicities. Herein we report an Iranian girl with a missed diagnosis of osteogenesis imperfecta. She was referred with the history of frequent fractures, and severe motor delay and was suspected to osteogenesis imperfecta. Following the case we detected refractory rickets instead of OI, sever growth failure, proximal renal tubulopathy and RTA, and enlarged kidneys, progressive hepatomegaly, and GSD on liver biopsy. Glucose and galactose tolerance tests confirmed abnormal carbohydrate metabolism. Molecular analysis on GLUT2 gene revealed a homozygous novel mutation in exon 5; it was 15 nucleotide deletion and 7 nucleotide insertion and caused a frame shift mutation, produced a premature truncated protein (P.A229QFsX19). This mutation has not been reported before in the relevant literature.

ABSTRACT

Introdução: osteogênese imperfeita (OI) é uma doença genética caracterizada por diminuição da massa óssea, fraturas e outras alterações do tecido conjuntivo. Geralmente, ocorre por mutações em genes do colágeno tipo 1. Pode ser classificada nos tipos I a IX. Objetivo: estimar a incidência de OI e a frequência de seus tipos na Maternidade do Hospital das Clínicas ? UFMG (HC-UFMG) entre novembro/1990 e dezembro/2007, identificar fatores associados à doença, achados ultrassonográficos pré-natais mais frequentes e porcentagem de casos de novo. Métodos: estudo retrospectivo baseado no banco de dados da Maternidade do HC-UFMG, vinculado ao Estudo Colaborativo Latino-Americano de Malformações Congênitas (ECLAMC). Identificados recém-nascidos vivos (RNV) e natimortos (NM) com diagnóstico de OI e seus achados ultrassonográficos.Entre os RNVs, foram estudadas associações com peso ao nascer, gênero, idade e paridade maternas utilizando os testes do qui-quadrado e exato de Fisher. Resultados: a incidência foi de 1:1.415, com 30 casos de OI (26 RNV e 4 NM) em 42.443 nascimentos, 16,7% tipo I, 40% tipo IIA e 40% tipo IIB/III. Houve associação com peso ao nascer ? 2.500 g. Os achados ultrassonográficos mais comuns na OI-I foram encurtamento, encurvamento e fraturas de ossos longos e na OI-II, além dos achados anteriores, tórax em sino ou hipoplásico, diminuição da calcificação craniana, osteopenia, bossa frontal, platispondilia e dilatação de ventrículos. Todos os casos de OI-II e 80% dos casos de OI-I ocorreram por mutação de novo ou mosaicismo gonadal. Conclusões: a incidência encontrada foi mais alta que a descrita, provavelmente por ser o HC-UFMG um hospital de referência. Associação com baixo peso provavelmente foi conseqüência da doença. O ultrassom fetal permitiu a suspeição pré-natal do diagnóstico.


Introduction: osteogenesis imperfecta (OI) is a genetic disease characterized by decreased bone mass, fractures and other disorders of connective tissues, usually due to gene mutations in collagen type I to IX. Objective: to evaluate the OI incidence and frequency of its types in the UFMG Hospital das Clinicas Maternity ( HC- UFMG) between November 1990 and December 2007, to identify the disease related factors, more frequent prenatal ultrasound findings and new cases percentage. Methods: retrospective study based on the database of the HC Maternity-UFMG, linked to the Estudo Colaborativo Latino-Americano de Malformações Congênitas (ECLAMC ) / Latin American Collaborative Study of Congenital Malformations. Identified live births (LB) and stillborn (SB) with OI diagnosis and their sonographic findings. Among the LB the study included relations with birth weight, gender, maternal age and parity using chi-square and Fisher exact tests. Results: the incidence was 1:1.415, with 30 OI cases (26 LB and 4 SB) in 42.443 births, 16,7% type I, 40% type IIA and 40% type IIB/III. There was association with birth weight? 2.500 g. The most common sonographic findings in the OI-I were shortening, bowing and fracture of long bones and in the OI-II, in addition to previous findings, bell or hypoplastic thorax, decreased cranial calcification, osteopenia, frontal bossing, platispondilia and dilated ventricles. All cases of OI-II and 80% of OI-I cases occurred by new mutation or gonadal mosaicism. Conclusions: The incidence was found higher than reported, probably because the HC- -UFMG is a referral hospital. Association with low birth weight was probably a consequence of the disease. The fetal ultrasound allowed the suspected prenatal diagnosis.

ABSTRACT

Background: Osteogenesis imperfecta (OI) is a rare metabolic bone disorder characterized by increased bone fragility, low bone mass, recurrent fractures and numerous extra-osseus features. Many patients remain undiagnosed and unattended particularly in developed countries. Presently, medical management with bisphosphonates has changed the scenario. Materials and Methods: Twenty consecutive patients of OI were enrolled over a period of four years. Their clinical features, radiology, and biochemical parameters and treatment outcome were analysed. Results: Of the 20 patients, 16 (80%) were male and 4 (20%) were female. Mean age (SD) of the patients was 20.8 (13.8) years. All the patients had presented with fractures, the number of fractures per person varying from 1 to 20. Long bones were predominantly involved and thirteen (65%) had deformities of long bones. Ten (50%) had a positive family history of fractures after trivial traum. Eleven (55%) patients had dentiginous imperfecta (DI) and ten (50%) had blue sclerae at presentation. Impaired hearing was present in 1 patient only. Calcium profile was normal. Nine patients received pamidronate. Fracture frequency and pain decreased remarkably in these patients. Conclusion: Patients with OI presented late, predominantly with fracture of long bones, deformities and blue sclerae. Pamidronate therapy remarkably decreased fractures and pain in these patients. ©

ABSTRACT

Un programa de vigilancia epidemiológica de malformaciones congénitas en efecto en el Hospital Ruíz y Páez de Ciudad Bolívar desde Abril de 1978, nos ha permitido la detección de 25 casos de Osteocondrodisplasias (OCD) en un total de 70.152 nacimientos atendidos en dicho hospital hasta Agosto de 1990, para una prevalencia total de un caso de OCD por cada 2.806 recién nacidos. Las entidades nosológicas encontradas fueron las siguientes: Acondroplasia, Displasia Tanatofórica, Osteogénesis Imperfecta II-A, Displasia Metafisaria de Kniest, Síndrome de Conradi-Hunnerman, Displasia Metafisaria de Jansen, Acondrogénesis de Parenti-Fracaro y Displasia Tóraco-Asfixiante de Jeune. Los resultados aquí reportados indican que este tipo de enfermedades representan un grupo relativamente importante de entidades nosológicas hereditarias que suman no menos de 200 casos nuevos anuales en el país. Esta relativa alta frecuencia, sus diferentes mecanismos hereditarios, sus variables complicaciones y sus índices de morbi-mortalidad, hacen que los pacientes afectados por una OCD constituyan un grupo problemático que no recibe, en general, la atención médica adecuada a su diagnóstico, asesoramiento genético y manejo de complicaciones
