Traumatic intra-sphenoidal pseudoaneurysm lodged inside the fractured sphenoidal sinus.

We describe a case of traumatic intra-sphenoidal right internal carotid artery pseudoaneurysm lodged inside the fractured sphenoidal sinus that developed in a patient with a previous history of frontal and skull base fractures involving the sphenoid sinus and walls of the carotid canal, but with normal intracranial findings at early CT angiography. The patient presented two episodes of massive life-threatening delayed epistaxis before successful endovascular treatment combining the use of coils and an uncovered stent was instituted. This case report highlights that patients with head trauma who present sphenoid sinus fractures with or without massive epistaxis should be evaluated for the development of traumatic internal carotid artery pseudoaneurysm as soon as possible. If the first angiographic evaluation reveals normal findings, repeated epistaxis should prompt a second angiographic evaluation because psudoaneurysm takes time to develop. Early treatment with uncovered stent of the aneurysm can be a life-saving therapeutic approach.

Surgical treatment of a case of adult epiglottic laryngomalacia.

INTRODUCTION: Adult laryngomalacia is rare. It may be idiopathic or secondary to trauma or degenerative disease. CASE REPORT: A 25-year-old man presented with inspiratory dyspnea on effort of several months' evolution. Flexible endoscopy found epiglottic laryngomalacia, managed by CO2 laser V-shaped partial epiglottectomy. DISCUSSION: Excessive resection of the epiglottis may lead to false passage; insufficient resection risks being ineffective. V-shaped partial epiglottectomy minimizes risk of false passage while ensuring permanent respiratory airflow via the epiglottic V during epiglottic movement.

Cochlea size variability and implications in clinical practice.

THE OBJECTIVES OF THIS STUDY WERE: 1) study cochlea size variability among age and degree of deafness; 2) calculate the length of the cochlear implant electrode needed to obtain the optimal final insertion depth angle of 270°. A total of 241 patients (482 ears) that underwent high resolution computed tomography (HRCT) of the ear in our Institution between 2003 and 2008 were included to collect temporal bone data, and were divided in 3 groups: 97 (194 ears) patients with bilateral severe or profound sensorineural hearing loss (Group A), 70 patients (140 ears) with bilateral moderate sensorineural hearing loss (Group B), 74 patients (148 ears) without sensorineural or mixed hearing loss (Group C). In each of the 3 groups, 5 subgroups were identified with the following age criteria: 1) subgroup 1: subjects ≤5 years old; 2) subgroup 2: subjects 6-10 years old; 3) subgroup 3: patients 11-15 years old; 4) subgroup 4: patients 16-20 years old; 5) subgroup 5: subjects >; 20 years old. The length of the cochlea, height of the cochlea, basal turn lumen diameter (BTLD) and volume of the cochlea were measured. The Mann-Whitney test was used to assess the alternative hypothesis that a statistically significant difference in size exists between the different groups and subgroups. The following equation was adopted to calculate the length of a straight electrode which follows the outer wall of the scala tympani required to obtain the ideal insertion depth angle of 270°( LIC ): [Formula: see text] . We found that the cochlea is completely developed and has reached adult size at birth. The degree of deafness does not affect the length or volume of the cochlea, while it can affect the height and BTLD. To assist the surgeon to calculate the ideal insertion depth angle of 270° in order to preserve residual hearing, it is useful to propose a straight electrode with 3 landmarks on the array (the first at 16.635 mm from the tip, the second at 17.987 mm and the third at 19.34 mm).

Role of ultrasonography in the diagnosis and follow-up of pediatric eosinophilic gastroenteritis: a case report and review of the literature.

Eosinophilic gastroenteritis (EG) is a rare disease characterized by the infiltration of one or more layers of the digestive tract by eosinophilic leukocytes. The diagnosis is confirmed by histological examination of a characteristic biopsy, but radiological features are useful for diagnostic suspicion. We report the case of an adolescent boy with recurrent epigastric pain, nausea and vomiting, in whom sonographic features and eosinophilia of the peripheral blood suggested the diagnosis of EG. Moreover, we reviewed the radiological features of EG with particular regard to the role of sonography in the diagnosis and follow-up of EG, especially in children. We emphasize the utility of sonography in pediatric patients presenting with gastrointestinal symptoms, since it may provide useful information in a quick, inexpensive and noninvasive way. Ultrasonographic detection of features such as bowel wall thickness, ascites and peritoneal nodules may be largely suggestive of EG and may prevent other invasive exams and abdominal surgery. Ultrasonography can also be easily used in the follow-up of these patients, and may obviate the frequent and potentially dangerous exposure to radiation.

Imaging spectrum of EBV-infection in a young patient.

A wide variety of atypical presentations with complications affecting multiple organ systems during acute infectious mononucleosis (IM) is described in the literature, with an increase in the number of teenagers who are susceptible to a severe case of the disease. We report a case of a 14-year-old girl with severe IM and acute abdominal pain. Ultrasonographic (US) evaluation showed a marked thickening of the gallbladder wall (GBW) with enlargement of some mesenteric lymph nodes. CT scan showed multiple enlarged lung nodules of various sizes and a small pleural and pericardial effusion; a hypodense solid mass of unknown etiology was detected in the anterior mediastinum, mimicking a malignant tumor. Hematological analysis of peripheral blood smear was performed to exclude neoplastic pathology. IM was identified as the only underlying disease. The patient was carefully monitored: clinical evaluation, laboratory analysis and US examination were repeated at weekly intervals, until recovery.

Lack of association between antiphospholipid antibodies and migraine in children.

Anticardiolipin antibodies are found frequently in those suffering from migraine, but it is not clear if this association is real or coincidental. Moreover, there are no data on the prevalence of anticardiolipin antibodies in children. In this study, 40 patients were divided into two groups according to the type of migraine: group I included 22 cases (15 females and 7 males, mean age+/-SD 13.7+/-8.9 years) suffering from migraine with and without aura; group II consisted of 18 children (10 females and 8 males, age 14.7+/-6.9 years) having migraine with prolonged aura or migrainous infarction, also called complicated migraine. We studied two groups of children as controls: a group of 35 children (25 females and 10 males, mean age 13.9+/-7.1 years) with juvenile chronic arthritis (group III) and a group of 40 healthy sex- and age-matched children who did not suffer from migraine or any other neurological disease (group IV). No statistically significant differences in levels of anticardiolipin antibodies were found between group I and II and controls. Our data demonstrate that, in children with migraine, anticardiolipin antibodies are not more frequent than in healthy controls, and suggest that anticardiolipin antibodies are not implicated in the pathogenesis of migraine.

Lack of mother-to-child HIV-1 transmission is associated with elevated serum levels of 90 K immune modulatory protein.

BACKGROUND: 90 K is a secreted human serum glycoprotein with immune modulatory activity. METHODS: Serum 90 K levels were determined by an enzyme-linked immunosorbent assay in 19 HIV-1-infected mothers at the time of delivery, in their new-borns (11 HIV-1 infected and eight uninfected), in 26 HIV-1-uninfected mothers and in 86 new-borns of HIV-1-uninfected mothers. RESULTS: 90 K levels in HIV-1-infected transmissive mothers (22.4 +/- 13.9 microg/ml) were similar to those of HIV-1-uninfected mothers (21.1 +/- 7.6 microg/ml; P = 0.715), but lower than those of HIV-1-infected non-transmissive mothers (45.5 +/- 24.8 microg/ml; P = 0.019). The levels were higher in HIV-1-uninfected (47.6 +/- 22.4 mg/ml) than HIV-1-infected (23.7 +/- 15.6 microg/ml; P = 0.014) new-borns of HIV-1-infected mothers. The new-borns of HIV-1-uninfected mothers had lower levels (11.7 +/- 5.3 microg/ml) than both HIV-1-infected and HIV-1-uninfected new-borns of HIV-1-infected mothers (all differences, P < 0.001). CONCLUSION: These results suggest that high 90 K protein serum levels in HIV-1-infected mothers and their new-borns are associated with lack of mother-to-child HIV-1 transmission.

Elevated levels of circulating immunostimulatory 90K in Henoch-Schoenlein purpura.

In order to clarify the immunologic reaction present in Henoch-Schoenlein purpura (HSP), 20 children (11 boys and 9 girls; median age, 5.8 +/- 2.8 years) with HSP and 20 sex- and age-matched healthy children were studied. The 90K/Mac-2 BP serum concentrations were significantly higher in the patients than in the healthy controls (12.5 +/- 7.5 vs 4.5 +/- 2.7 micrograms/ml, respectively; P < 0.0001). 90K/Mac-2 BP values higher than the cutoff value were observed in 13 of 20 (65%) patient. The soluble intercellular adhesion molecule 1 concentrations were significantly higher in HSP patients than controls (P < 0.0001), with mean values of 1631 +/- 703 and 85 +/- 16 ng/ml, respectively. The 90K/Mac-2 BP serum levels were significantly correlated with soluble intercellular adhesion molecule 1 (r = 0.90, P < 0.0001). Although the underlying causes of these immunological abnormalities are unclear, these observations suggest that the 90K/Mac-2 BP protein may play a role in the immunological reactions involved in the development of HSP.

Fetal encephalopathy with cerebral calcifications: a case report.

The authors report a case of a newborn with severe encephalopathy and cerebral calcifications. The newborn was admitted to Neonatal Intensive Care Unit in Chieti at 2 days of age suffering from continuous generalized seizures. He was the child of healthy first-degree cousins. Cerebral ultrasonography showed bilateral ventricular dilatation and an intrathlamic hyperechoic image. Computed tomography and magnetic resonance imaging showed ventricular and corpus callosus hypoplasia, pachygyria, widespread delayed myelination areas, and basal nuclei and periventricular calcifications. All serum and urine analyses showed normal results. In particular, all demyelinizing metabolic diseases were excluded. Based upon these findings, we speculate that this infant may be suffering from fetal encephalopathy with cerebral calcifications.

[Clinical study on the prevalence of dental caries in patients with juvenile diabetes mellitus]. / Indagine clinica sulla prevalenza della carie in pazienti con diabete mellito giovanile.

The authors present the results of a epidemiological transversal study concerning 26 type I diabetic patients: as a control have been observed 24 healthy subjects, similar for age and sex to the diabetic patients. The results show a higher incidence of caries in diabetic patients than in the healthy subjects; this is probably due to the high carbohydrates diet of the young patients.

[The families of diabetic children: a 2-year follow-up]. / Studio su famiglie di bambini diabetici: follow-up di 2 anni.

A great amount of clinical and experimental evidence has been accumulated on the role of immunological early events in the development of type 1 diabetes mellitus. In order to try to make a precocious diagnosis of type 1 diabetes mellitus, the Authors have studied all the components of the family in a group of diabetic children. This study is a part of a collaborative International Study called IFS (International Family Study). The Authors describe the scheme of this project in detail. During this study the Authors made a very early diagnosis of diabetes in a child, brother of another diabetic boy. The importance of this approach to the diabetic disease is discussed.
