Superior sagittal sinus thrombosis after internal jugular vein cannulation.

A case of cerebral venous sinus thrombosis after central venous cannulation is presented. This occurred after a catheter had been in place for 5 days. The patient presented with thrombosis of the left internal jugular vein 4 days after removal of the catheter. Despite anticoagulation, the patient developed symptoms of increased intracranial pressure. Subsequently, a diagnosis of superior sagittal sinus thrombosis was made. The aetiology, diagnosis and management of this uncommon complication of central venous cannulation are discussed.

An unusual complication of tracheal intubation.

We report a previously undescribed complication of tracheal intubation. The complication arose as a result of tracheal intubation performed as an emergency procedure in a patient with an abnormal anteriorly placed larynx. Subsequent corrective laryngeal surgery was required after a temporary tracheostomy had been performed.

Diaphragmatic weakness in hereditary motor and sensory neuropathy.

Six patients severely affected by hereditary motor and sensory neuropathy (HMSN), four type I and two type II, had clinical evidence of diaphragmatic weakness. One presented with cardiorespiratory failure secondary to nocturnal hypoventilation, and three others were unable to lie flat because of dyspnoea. Diaphragmatic paralysis should be considered as a cause of respiratory or cardiac failure in cases of HMSN.

Prevalence of mandibular dysfunction in 10-18 year old Israeli schoolchildren.

The prevalence of mandibular dysfunction in a sample of 369 Israeli schoolchildren was found to be 56.4%, indicating that one or more of the cardinal symptoms were present. It increased with age from about 51% in the 10-13 year old group to 67.8% in the 16-18 year olds. The most common cardinal sign of dysfunction was joint sounds (35.8%), which increased with age from 28% in the youngest group to 44.3% in the oldest group. The second most common sign was joint sensitivity to palpation (30.4%), which showed a slight increase in the oldest group. Sensitivity of the superficial muscles was recorded third, with 20%. Joint pain and restriction of mandibular movement appeared infrequently. Two of the more common cardinal symptoms, namely joint sounds and muscle sensitivity, were statistically related to several possible aetiological factors and to age and sex. Analysis of association showed that the probability of muscle sensitivity increased in the presence of malocclusion and/or joint sensitivity to palpation. It also showed that age, occlusal wear, locking of the jaw and joint sensitivity to palpation increased the probability of joint sounds.

[Early maladaptive processes, depression and alexithymia in suicidal hospitalized adolescents].

Alexithymia characterizes people having important difficulties in putting their feelings and moods into words. Adolescents' depression shows some peculiarities: one of them, which is often observed, is the equal difficulty of imparting one's feelings to others. This research concerns adolescents who attempted suicide. We study classical factors: depression and hopelessness. But our main objective is at first to study the relationship between attempted suicide, depression, hopelessness and alexithymia. The second objective of our study deals with the the prominent part of early schematas in this complex inter-relation. Maladaptative early schematas are no doubt involved in dysfunctional schematas found in depression and hopelessness. As a consequence, we would like to verify the following hypothesis: maladaptative early schematas are very numerous and specific among adolescents who attempted suicide. These schematas are the core of the complex inter-relation between attempted suicide, depression, hopelessness, suicide risk, suicide relapse and alexithymia. We have compared a group of normal subjects (who did not try to take their owns lives) and a group of people who did. First, we have found that the latter are more prone to alexithymia: a large majority of these subjects exceeds by far the accepted norm of the Toronto Alexithymia Scale. We have proved that the subjects who have attempted suicide also accumulate maladaptative early schematas. The qualitative analyse of these schematas leads to a possible explanation of the tendency to self destruction. Moreover there are apparently important differences between subjects who, in the past-experienced or did not experience a major depressive episode. The analysis of the relationships between the various factors of our study brings us to the conclusion that there is an unmistakable causal link between maladaptative early schematas and the interactive set (depression-hopelessness-major depressive episode-alexithymia) all these being part of attempted suicide and forming an integrant part of a whole which is the vulnerability to the suicide. Studying the various steps of early schematas seems to be quite promising as far as depression and suicide are concerned.
