Magnetic resonance imaging of the parotid glands and lip biopsy in the evaluation of xerostomia in Sjögren's syndrome.

Magnetic Resonance Imaging (MRI) of the parotid glands was performed in 23 patients with dry mouth. Each patient underwent lip salivary gland (LSG) biopsy and complete clinical and immunological assessment. MRI showed a quite specific nodular pattern in the parotid glands of patients with Sjögren's syndrome (SS), especially those with severe histologic abnormalities in LSG. However no significant correlation could be detected between MRI score and both LSG biopsy class and immunological abnormalities. MRI of the parotid glands can be regarded as a useful noninvasive procedure with high positive predictive value for the evaluation of the salivary component in SS.

[Water disinfection of dental treatment units using ozone].

The disinfecting effect of ozonized water has been investigated. Under the precondition that the dental chair had been thoroughly sanitized, the system showed a good disinfecting effect. Finally, for reasons of practical medical treatment, the ozone concentration in air and, for reasons of hygiene in drinking water, the ozone concentrations in water were determined under various conditions. In addition, the influence of continuous-flow water heaters is discussed. The problem of continuous-flow water heaters regarding their effects on the colonisation of water by microbes proves not to be significant. The exposure of patients to disinfectants is discussed.

[Griffith test in the evaluation of psychomotor development in the 1st year of life. A longitudinal study].

Griffith psychometric test has been experimented on a group of 20 healthy newborn infants, monitored during their 1st year of life with quarterly check-ups. It was clear that the development general rates were constantly higher than the original values reported by the English author. In particular, in 12 months old infants, the rates appeared significantly higher than the rates observed on the same Italian specimen in past periods. A transverse and longitudinal study of the psychomotor development of subjects included in the specimen has given the opportunity to verify some of his features. The development outlines, traced by employing the average rates relevant to the 5 different aspects monitored (motor, personal-social, language, eye-hand co-ordination, practical reasoning), appeared to be well-balanced, that is without dissynchronisms between the different scales. The only exception being the scale of the social behaviour, were the average rates appear to be sensibly higher at every age. Individual development outlines, on the contrary, appeared to be disjointed in all aspects (except for 4 cases). In the longitudinal analysis then, some noteworthy oscillations in both general and partial rates, were observed among the controls carried out in subsequent periods in all the subjects.

[Apnea during sleep and wakefulness in term newborns].

Apneas in the different sleep states are commonly observed in the full-term healthy newborn infant. Central and short apneas prevail whilst apneas greater than 15 sec. are rare; a marked incidence of short apneas (less than 10 sec.) was observed in active sleep, even though apneas are not exclusive of active sleep. There is a strong inter-individual variability of apnea incidence. Apnea incidence in a state is not positively correlated to apnea incidence in different behavioural states: on the contrary there seems to be an opposite correlation between incidence in AS and QS. Apnea occurrence is positively correlated, in individuals, to the periodic breathing percentage. Apneas number and their duration is markedly lowered already in the second month of life. Periodic breathing must be considered a feature of immaturity. Obstructive apneas are less frequent than central apneas: their survey requires sophisticated technics with the aid of simultaneous recording of several breathing parameters. Relationship between central apneas/ obstructive apneas and mixed apneas is not known. Certainly obstructive and mixed apneas occurrence has been underestimated because of technical difficulties deriving from their survey. The meaning of an incidence of short apneas markedly higher than normal in full-term newborn infants is controversial and not clear, individuals with long apneas and subjects with short apneas in excess have been considered infants at SIDS risk. It is not clear whether periodic breathing and apneas depend on a common pathogenesis; the correlation between high incidence of periodic breathing in postnatal period and SIDS risk is still controversial. Few Authors suggest to treat newborn infants with extended apneas in sleep and considerable percentage of periodic breathing with aminophylline. The relation between gastro-oesophageal reflux and apnea has been recently evidenced. Central apneas and obstructive apneas during breast and bottle feeding have also been documented. Differently from pre-term infant apneas, bradycardia, although not exceptional, is not frequent during apneas in full-term newborn infants.

[A severe case of bronchial pneumonia due to Mycoplasma pneumoniae accompanied by immunosuppression, thrombophlebitis and hepatitis resolved with human immunoglobulins].

We present a case of severe pneumonia by Mycoplasma pneumoniae, whose clinical course was complicated by immunodepression, hepatitis and deep venous thrombosis. Treatment with pepsin-treated human immunoglobulins was unsuccessful, whereas prompt recovery was obtained by infusion of human immunoglobulins treated at pH 4.

Replantation of avulsed primary anterior teeth: treatment and limitations.

In addition to the successful replantation of avulsed permanent teeth, the replantation of primary anterior teeth may also be indicated. The decision is based on age and stage of tooth development, development of dentition, storage of the avulsed tooth and the way it is transported to the treatment site, the appropriate in vitro treatment of the tooth before reinsertion, and the willingness of the child to cooperate. A method involving retrograde filling of the primary tooth root with calcium hydroxide after resecting the root apex has proved successful. Other commercially available root filling materials and pins are not indicated. Calcium hydroxide allows the tooth to heal in place without reaction and prevents the development of apical periodontitis. As regards any surgical intervention, the attending dentist in this case has to weigh the benefits against the risks.
