Diagnosis Of Joubert Syndrome Research Articles

Recognition of the clinical signs and symptoms of Joubert syndrome.

Joubert Syndrome is a rare, autosomal recessive disorder that affects the cerebellum and brain stem. It presents with a distinct respiratory pattern and profound tachypnea in the newborn period. This article provides an overview of the condition and discusses the embryologic origins of this syndrome. A focused history and systematic physical assessment provide a step-by-step guide to enhance the early recognition of clinical signs and symptoms of this disorder. A series of clinical photographs and a brief case report offer insight into the classic presentation of this uncommon disorder. The diagnosis of Joubert syndrome is confirmed with magnetic resonance imaging, which reveals a classic neuroradiologic finding, characterized as the molar tooth sign. A discussion of the range of developmental outcomes and complex multispecialty care and intensive support that these infants and their families require is also provided.

Síndrome de Joubert: presentación de cinco casos

To review clinical features, radiological findings and prognosis in Joubert syndrome. We report 5 children (3 male and 2 female) with the diagnosis of Joubert syndrome by clinical and radiological findings. They were diagnosed in the first year of life, in the Hospital Infantil La Paz (Madrid, Spain), from 1971 to 1996. Three patients have already been published, and here, we report two new cases. Partial absence of the cerebellar vermis, hypotonia and developmental delay were seen in all patients. Other cardinal findings were episodic hyperpnoea (5/5) with periods of apnoea (2/5), abnormal eye movements (2/5) and strabismus (3/5), tongue protrusion (2/5), seizures (1/5), hemifacial spasms (1/5) and occipital meningocele (2/5). Clinical manifestations were first noticed soon after birth. Two patients died in the first 5 years of life, and the rest of the cases actually show severe mental retardation. Joubert syndrome is a rare and probably underdiagnosed syndrome with bad prognosis. This inherited condition is characterized by agenesis of the cerebellar vermis, mental retardation, hypotonia, episodic hyperpnoea and abnormal eye movements. Additional manifestations have been reported since the original cases were described.

Joubert syndrome: a review.

We review 72 previously reported and 29 new patients with the possible diagnosis of Joubert syndrome. We define diagnostic criteria for this syndrome and present the data available in 94 patients that fulfill our criteria. We present the data regarding the clinical, neuroradiological, and ophthalmological manifestations and the prognosis of these 94 patients. We propose a classification of the patients with this diagnosis in 2 groups: those with retinal dystrophy and those without. Retinal dystrophy runs true in families and was never absent when renal cysts were reported.
