[Maxillary sinusitis in children: clinical and diagnostic aspects]. / Le sinusiti mascellari in età pediatrica: aspetti clinici e diagnostici.

Acute or chronic sinusitis is often overlooked and poorly understood in the pediatric population as many children have frequent episodes of upper respiratory infections that confuse accurate diagnosis. The authors present a prospective study in 89 children with clinical and radiographic presence of maxillary sinusitis in order to underline the most frequent clinical symptoms and signs and the most significant diagnostic procedures that help confirm precise definition of this common disease. The authors also discuss the relationship with allergic factors, clinical causes of poor sinus drainage, and environmental factors that may increase the possibility of sinus infection.

[Cohen syndrome. Contribution to its clinical delineation]. / La sindrome di Cohen. Contributo alla sua delineazione clinica.

The authors report a case with features of the Cohen syndrome: characteristic cranio-facial appearance with prominent nasal bridge, short philtrum, prominent upper central incisors, micrognathia, truncal obesity of mid-childhood onset, muscle hypotonia, mental deficiency, limb anomalies associated with other clinical expressivity present among the previous reported cases. The reported case is of particular interest: the distal limbs anomalies are peculiar with marked shortening of metacarpals and metatarsals. A review of the other cases is also reported and discussed in order to stress the most frequent manifestations of the syndrome and delineate the major clinical characteristics.

[Umbilical cord IgE: a test for sensitivity, specificity and predictive value of atopy?]. / IgE cordonali: test di sensibilità, specificità e predittività di atopia?

Total IgE cord serum levels were measured in 200 newborns in the Hospital of Viadana-Bozzolo and familial allergic conditions were investigated in all the cases. In a 6 month follow up study attention was focused on the development of atopic symptoms. The sensibility, specificity and predictive value of the total IgE cord serum levels are discussed and the introducing of preventive measures in the at risk newborns is also questioned.

[Reye's syndrome. Clinical and etiopathogenetic aspects. Case contribution]. / La sindrome di Reye. Aspetti clinici ed eziopatogenetici. Contributo casistico.

In this study the authors report a case of Reye syndrome in a three year old patient. The most likely etiopathogenetic mechanisms are analysed and incidence, clinical features and diagnostic criteria are discussed. The possible association between the development of Reye's Syndrome and the use of salicylates, particularly aspirin, during the preceding viral infection (influenza or chicken pox) is emphasized. We underline the importance of early diagnosis that facilitates the successful management of Reye's Syndrome.

[Hemifacial microsomia. Description of a case with associated rare multiple visceral anomalies]. / Microsomia emifacciale. Descrizione di un caso con rare anomalie viscerali multiple associate.

A case of hemifacial microsomia is reported in association with rare cardiac, lung and laryngeal abnormalities. Our case presents both atrial and ventricular septal defects, hypoplasia of the right lung and of the larynx. This variety of malformations is rarely present in other reported cases. The literature of hemifacial microsomia is reviewed and differential diagnosis is discussed.
