[The temporomandibular joint compromise as a cause of acute and chronic headaches and other otoneurological symptoms].

Objectives: The aim of this work is to introduce a new condition within temporomandibular disorders, temporomandibular joint compromise (TMJC), a mandibular movement limiting disorder of extra-articular traumatic cause, and evaluate the response rate and safety of treatment. The limiting cause of mandibular movement is the lack of space between the mandibular ramus and maxilla. The main symptoms of TMJC include headache, dizziness, and tinnitus.

Computed tomography diagnosis of symptomatic right paraduodenal hernia associated with enteric duplication cyst.

Paraduodenal hernias rarely present with symptoms in children. We report a case of a right paraduodenal hernia associated with enteric duplication cyst that caused intestinal suboclussion in a 9-month-old female infant. Paraduodenal hernia was detected by contrast-enhanced computed tomography.

[Moebius syndrome. Three different forms of presentation].

Introduction: Moebius's syndrome is an entity present at birth, characterized by oculofacial paralysis and external ophthalmoplegia. Other cranial nerves can also be affected and associated to skeletal abnormalities and neurologic symptoms. It appears sporadically, sometimes of familiar nature, presenting special facies with total absence of facial expression and severe strabismus.

[Renal volumetric echography in the newborn infant with an agenetic, dysplastic or obstructive contralateral kidney].

In newborn babies with congenital renal pathology type agenesia, dysplasia or obstruction is very important to know if there is intrautero vicariant growing of the contralateral kidney. To find out that we have proceeded to be ultrasound volume measurement of the normal renal unit, as this is a valuable parameter related to compensatory mechanisms. We have studied by ultrasounds 28 renal units (16 right, 12 left) in newborns with contralateral pathology: pyeloureteral stenosis in 10 cases, multicystic kidney in 13 cases, renal agenesia in 3 cases, obstructive ureterocele in 1 case and another one with ureterovesical stenosis.

[Volvulus of the small intestine. Contribution of abdominal echography to early diagnosis].

We report six cases of small intestine volvulus associated to malrotation, out of a whole of 11 volvulus managed by us in the last six years. None of them were diagnosed with the only help of clinical and conventional radiological explorations. In the other three cases the diagnosis was made through ultrasounds explorations: It showed the mesenteric vein on the left side of the mesenteric artery.

Hepatic hamartoma in a newborn.

In a newborn infant with heart failure and hepatomegaly the radiological findings suggested hepatic haemangioendothelioma, but subsequently the tumour proved to be a hamartoma.

[Indications of "post mortem" radiologic study in pediatrics (author's transl)].

The role of the radiological "post mortem" study (PMRS) is comment with special emphasis on the most important indications. The PMRS was performed in 959 children during five years. The PMRS do not pretend top be a substitute of the necropsy but a complement and in the case that the parents do not give the authorization for necropsy, the only tool for explain the cause of death.

Mastocytosis with skeletal and gastrointestinal involvement in infancy. Two case reports and a review of the literature.

Two cases of mastocytosis with skeletal involvement in children three and six months old are reported. Bone lesions, either sclerotic or lytic, were encountered in their skeletal surveys. Gastrointestinal lesions in children with mastocytosis are exceedingly rare; in addition to skeletal lesions, one of our patients had a large duodenal ulcer.

Indications for pneumoperitoneum in the diagnosis of congenital anomalies in the umbilical region.

Thirty pneumoperitoneograms were performed postmortem and 5 were performed for diagnosis: the technique itself, the radiological anatomy of the umbilical region, and the usefulness of the procedure in diagnosis are discussed. Pneumoperitoneum may be indicated in the investigation of a bleeding Meckel's diverticulum, in the exclusion or confirmation of remnants of the omphalomesenteric duct, in chronically moist lesions of the umbilicus resistant to symptomatic treatment, in suspected cases of non-communicating urachal cysts which cannot be diagnosed by cystogram, and in the differential diagnosis of abdominal tumours related to the umbilical region.
