[The temporomandibular joint compromise as a cause of acute and chronic headaches and other otoneurological symptoms]. / El compromiso articular temporomandibular como causa de cefaleas agudas y crónicas y otros síntomas otoneurológicos.

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. In many cases, the headache is previously diagnosed as a migraine. METHODS: Data were collected from 54 patients aged between 6 and 59 years that had a confirmed diagnosis of migraine according to the 3rd Edition of the International Headache Classification of the International Headache Society of 2018, and were treated for TMJC in a dental clinic. They also presented with other otolaryngological symptoms. A retrospective quasi-experimental study without a control group was carried out due to ethical considerations related to the harmless nature of the treatment. RESULTS: After treatment of TMJC, migraine symptoms disappeared in 52 patients (96.3%, P<.001), and persisted, although with clinical improvement, in 2 (3.7%). There was also an improvement in the other associated symptoms: dizziness disappeared in 23 out of 27 affected patients (85.21%, P<.001), and tinnitus disappeared in the 31 affected patients (100%, P<.001). No significant treatment-related side effects were observed. CONCLUSIONS: This study shows the high rate of response and safety of the treatment of TMJC.

Tiroides ectópico: causa rara de tumoración cervical en el niño / Ectopic thyroid: a rare cause of a neck mass in a child

Se denomina tiroides ectópico a la presencia de tejido tiroideofuncionante en una localización diferente a su posición normal pretraqueal. Su prevalencia en la población general es muy baja, y es una causa rara de tumoración cervical. Presentamos el caso clínico de una niña de 8 años de edad con una tumoración cervical asintomática, que fue diagnosticada de tiroidesectópico cervical. En el niño con tumoración cervical, la localización habitual de la glándula tiroides en su posición normal mediante ecografía es un método fiable e inocuo para excluir el tiroides ectópico y evitar su exéresis inadvertida. A pesar de su rareza, es un diagnóstico que debe considerarse en la evaluación de todo niño con tumoración cervical(AU)

Ectopic thyroid is the presence of functional thyroid tissue at a site other than its normal pretracheal position. Its prevalence in the general population is very low, and it rarely produces a mass. Here, we present the case of an 8-year-old girl with a neck mass that was diagnosed as ectopic thyroid tissue. In children with neck masses, the location of the thyroid gland in its normal position by routine ultrasound scan is a reliable and noninvasive method of ruling out ectopic thyroid and avoiding its inadvertent excision. In spite of its rarity, this diagnosis should be considered in the evaluation of any child with a neck mass(AU)

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. In a review of the English-published literature, we have not found other reports of the association of paraduodenal hernia and enteric duplication cyst. A high index of suspicion is required for detecting paraduodenal hernias in children, and abdominal computed tomography is the most specific imaging study for their preoperative diagnosis.

[Moebius syndrome. Three different forms of presentation]. / Síndrome de Moebius. Tres formas diferentes de presentación.

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. The pathogenesis of the syndrome still remains unknown, being the transitory situation of fetal hypoxia/ischemic the most accepted theory. In some cases chromosomal abnormalities have been detected. CLINICAL CASE: We reported three children with different symptoms, two of them are siblings whose father is affected, but he was not diagnosed until adult age. CONCLUSIONS: We conclude pointing out the different presentation of the disease, the appearance in several members of a family and its chronically evolution.

[Renal volumetric echography in the newborn infant with an agenetic, dysplastic or obstructive contralateral kidney]. / Volumetría ecográfica renal en el recién nacido con riñón contralateral agenésico, displásico u obstructivo.

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. We considered renal function, length of the larger renal axis width and depth of the kidney mass. Renal function was normal in all cases. Analysis of objectives results show a clear difference between the volume of normal Kidneys in children with contralateral pathology and the control group constituted by 42 renal unit in normal newborns without urological pathology. We conclude with the real evidence of compensatory growing of the normal contralateral kidney during intrautero periods.

[Volvulus of the small intestine. Contribution of abdominal echography to early diagnosis]. / Volvulo de intestino delgado. Contribucion de la ecografia abdominal al diagnostico precoz.

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. Confirmation and resolution of the cases were reached with a laparotomy.

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)]. / Indicaciones del estudio radiológico "post mortem" en Pediatría.

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. The diagnosis of mastocytosis was established by skin biopsy in both patients. A review of the literature is also presented.

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.
