Ataxia in children: early recognition and clinical evaluation
Background: Ataxia is a sign of different disorders involving any level of the nervous system and consisting of impaired coordination of movement and balance. It is mainly caused by dysfunction of the complex circuitry connecting the basal ganglia, cerebellum and cerebral cortex.
A careful history, physical examination and some characteristic maneuvers are useful for the diagnosis of ataxia. Some of the causes of ataxia point toward a benign course, but some cases of ataxia can be severe and particularly frightening.
Methods: Here, we describe the primary clinical ways of detecting ataxia, a sign not easily recognizable in children. We also report on the main disorders that cause ataxia in children.
Results: The causal events are distinguished and reported according to the course of the disorder: acute, intermittent, chronic-non-progressive and chronic-progressive.
Conclusions: Molecular research in the field of ataxia in children is rapidly expanding; on the contrary no similar results have been attained in the field of the treatment since most of the congenital forms remain fully untreatable. Rapid recognition and clinical evaluation of ataxia in children remains of great relevance for therapeutic results and prognostic counseling

Cervical neurenteric cyst and Klippel-Feil syndrome: An abrupt onset of myelopathic signs in a young patient
Neurenteric cysts (NECs), also called enterogenous cysts or enterogenic cysts, are congenital malformative anomalies of endodermal origin that manifest with a variety of disorders, including spine anomalies. Neurenteric cysts are uncommon developmental disorders reported in 0.7%–1.3% of all spinal tumors. Klippel-Feil syndrome (KFS) defines a malformative spine disorder presenting with congenital fusion of cervical vertebrae and/or other parts of the spine. In patients with KFS, NECs are rarely reported; they may be silent for long periods of time, showing a slow progressive course or manifesting with an acute, severe neurological presentation or with fluctuating myelopathic symptoms. We report a young patient affected by KFS associated with a NEC which, in a short period of time, progressively caused myelopathic symptomatology. Surgical intervention resulted in resolution of the neurological signs. Keywords: Neurenteric cyst, Klippel-Feil syndrome, Intramedullary cys
Primary headaches in children: clinical findings on the association with other conditions.
The aim of the present study is to report on the frequency of some comorbidities in primary headaches in childhood. Two hundred and eighty children (175 males and 105 females; ratio 1.7:1), aged 4 to 14 years, affected by primary headaches were consecutively enrolled in this study. In direct interviews, parents and children gave information about the association of their headaches with different conditions including asthma and allergic disorders, convulsive episodes, sleep disorders and increased body weight, affections some time associated in the literature to headache as comorbidities. In addition, anxiety and depression, attention deficit/hyperactivity disorder, tics, learning disabilities and obsessive-compulsive disorders, using psycho-diagnostic scales were evaluated. Two hundred and eighty children matched for age, sex, race and socio-economic status, were used as controls. No significant association of primary headaches was found with asthma and allergic disorders, convulsive episodes, sleep disorders and increased body weight. Overall behavioral disorders were more common in children who experienced headache than in controls. A significant association of primary headache was found with anxiety and depression (p value <0.001), but not with the other psychiatric disorders. Primary headaches in children are not associated with most of the psychiatric and systemic conditions herein investigated. On the contrary, there was a significant association with anxiety and depression, as frequently reported in adults
Incidence of Mediterranean Spotted Fever in Sicilian children: a clinical-epidemiological observational retrospective study from 1987 to 2010
Background: Zoonoses are human infectious diseases caused by pathogens that primarily infect animals. Mediterranean Spotted Fever (MSF) represents one such example, affecting the Mediterranean region, in which household animals can be immune-carriers of infected ticks.
Materials and methods: We retrospectively analysed the incidence and the clinical and laboratory features of MSF caused by R.Conorii in children admitted to the Paediatric Operative Unit from 1987 to 2010, for persistent fever and generalised macular-popular erythematous lesions.
Clinical, immunological and serological parameters of 55 cases of Rickettsia infections observed in children between 2 and 11 years of age were collected.
Results: We found an increasing incidence of MSF in childhood from 1987 to 2010. Diagnosis of MSF at the moment of hospital admission was done in 16 patients (29.09%). The presence of the typical Tache noire was observed in 16 cases out of 55 patients (29.09% of cases).
We noticed a different representation of R. conorii antigens in serological testing over the time period of the study, corresponding to overall higher incidence rates for infection in the latter years. We also observed a higher incidence of infection in those years in which all four antigens were found positive at serum testing with respect to those years in which only two of the four antigens were observed (1987-1990: 0-16%; 2007-2010: 0.46%; P<0.005).
Conclusions: These changes in R. conorii antigenicity may be the cause of higher pathogenicity in this parasite, perhaps linked to increased immigration along with consequent changes in the epidemiology of infectious diseases in host countries
Acute Glomerulonephritis in a Child with Chlamydia pneumoniae Infection: A Case Report.
Background. Infectious diseases seem to be an important and independent risk factor for renal failure, but the underlying mechanism of renal involvement during some kinds of infectious diseases is still unclear, even if the literature data report immunomediated and/or autoimmune mechanisms to explain the pathogenic relationship between the two diseases. In paediatric patients, Chlamydia pneumoniae is a rare cause of renal complications and it may manifest in several ways, mainly involving the respiratory system, even if also renal and glomerulalr complications, have been described. Case Diagnosis/Treatment. Herein we report a case of a 3-year-old child who developed an acute glomerulonephritis that was chronologically, clinically, and biologically related to a previous Chlamydia pneumoniae infection. On our knowledge, in the literature it is the youngest patient with renal involvement during course of Chlamydia pneumoniae infection ever reported. Conclusions. The present case supports the hypothesis of a rather close causal relationship between this infective agent and renal and glomerular symptoms occurred in this child, during an acute episode of respiratory disease
Intronic Variant in CNTNAP2 Gene in a Boy With Remarkable Conduct Disorder, Minor Facial Features, Mild Intellectual Disability, and Seizures
Introduction: Mutations in the contactin-associated protein-like 2 (CNTNAP2) gene (MIM#604569) encoding for CASPR2, a cell adhesion protein of the neurexin family, are known to be associated with autism, intellectual disability, and other neuropsychiatric disorders. A set of intronic deletions of CNTNAP2 gene has also been suggested to have a causative role in individuals with a wide phenotypic spectrum, including Pitt-Hopkins syndrome, cortical dysplasia-focal epilepsy syndrome, Tourette syndrome, language dysfunction, and abnormal behavioral manifestations. Case presentation: A 10-years-old boy was referred to the hospital with mild intellectual disability and language impairment. Moreover, the child exhibited minor facial features, epileptic seizures, and notable behavioral abnormalities including impulsivity, aggressivity, and hyperactivity suggestive of the diagnosis of disruptive, impulse-control and conduct disorder (CD). Array comparative genomic hybridization (CGH) revealed a copy number variant (CNV) deletion in the first intron of CNTNAP2 gene inherited from a healthy father. Conclusions: A comprehensive description of the phenotypic features of the child is provided, revealing a distinct and remarkable alteration of social behavior not previously reported in individuals affected by disorders related to CNTNAP2 gene disruptions. A possible causative link between the deletion of a non-coding regulatory region and the symptoms presented by the boy has been advanced
Hopkins’ syndrome
Hopkins’ syndrome is a rare disease that affects the anterior horn of the spinal cord after an acute episode of asthma in children with atopic disease. A viral infection or immunological suppression in atopic subjects might be the cause of occurrence of this syndrome, although the mechanism due to the etiopathogenesis of the disease still remains unknown.In general, this disease is manifested by a few days to a few weeks after an acute asthma attack, with flaccid paralysis of one or more limbs and in some cases residual muscle atrophy. The response to corticosteroid therapy is good and rare the possibility of recurrence
Poland Syndrome with atypical malformations associated to a de novo 1.5 Mb Xp22.31 duplication
Poland's syndrome (PS; OMIM 173800) is a rare congenital syndrome which consists of absence or hypoplasia of the pectoralis muscle. Other features can be variably associated, including rib defects. On the affected side other features (such as of breast and nipple anomalies, lack of subcutaneous tissue and skin annexes, hand anomalies, visceral, and vertebral malformation) have been variably documented. To date, association of PS with central nervous system malformation has been rarely reported remaining poorly understood and characterized. We report a left-sided PS patient carrying a de novo 1.5 Mb Xp22.31 duplication diagnosed in addiction to strabismus, optic nerves and chiasm hypoplasia, corpus callosum abnormalities, ectopic neurohypophysis, pyelic ectasia, and neurodevelopmental delay. Since, to our knowledge, this features' association has not been previously reported, we argue that this case may contribute to further widening of the variability of PS phenotype
