Temporobasal, Transsphenoidal Meningoencephalocele Becoming Symptomatic with Spontaneous Cerebrospinal Fluid Rhinorrhea: Diagnostic Work-up and Micro…
2012
Background We report the rare case of an adult transsphenoidal meningoencephalocele and outline the microneurosurgical strategy. Clinical history, the findings of computerized tomography (CT) scans and magnetic resonance imaging (MRI), the microsurgical procedure, and histopathology are reported. Case Report A 54-year-old female patient complained about cerebrospinal fluid (CSF) rhinorrhea; a transnasal biopsy of a mass in the maxillar sinus prior to diagnostic work-up was performed elsewhere. Persisting CSF leakage prompted CT and MRI, which showed brain tissue extending from the left middle cranial fossa into the left sphenoid sinus through several bony defects. The diagnosis of a trans…
Malignant teratoma in Klippel-Feil syndrome: a case report and review of the literature
2015
Introduction: Klippel-Feil syndrome is characterized by a congenital fusion of cervical vertebrae. Intracranial teratomas are nongerminomatous germ cell tumors and they account for 0.3 to 0.9% of all intracranial tumors. Teratomas with malignant transformation refer to lesions which give rise to malignant cancer of somatic type. The association between tumors of dermoid origin and Klippel-Feil malformation is extremely rare. Only 23 other cases have so far been reported, and only one case of dermoid tumor with areas of dedifferentiation on squamous cell carcinoma has been described. Case presentation: We report the case of a 72-year-old white man with a 2-year history of gait and balance di…
Migraine and cranial autonomic symptoms in children and adolescents: a clinical study.
2014
The frequency of cranial autonomic symptoms in children affected by primary headaches is uncertain. The aim of our study was to estimate the frequency of symptoms in pediatric headaches and correlate it with main migraine characteristics. A questionnaire investigating the presence of cranial autonomic symptoms was administered to all children with primary headache for 2 years. A total of 230 children with primary headache (105 males, 125 females) were included. Two hundred two children were affected by migraine and 28 (12.2%) by other primary headaches. Cranial autonomic symptoms were significantly complained by migraineurs (55% vs 17.8%) ( P < .001) and by children with higher frequenc…
Late Pleistocene Human Evolution in Sicily: Comparative morphometric analysis of grotta di San Teodoro craniofacial remains.
2007
Late Pleistocene human evolution in Sicily: comparative morphometric analysis of Grotta di San Teodoro craniofacial remains. D'Amore G, Di Marco S, Tartarelli G, Bigazzi R, Sineo L. Source Laboratorio di Archeoantropologia, Soprintendenza per i Beni Archeologici della Toscana, Via dei Rossi 26/A, 50018 Scandicci, Firenze, Italy. Abstract The paleoanthropological remains from Grotta di San Teodoro near Acquedolci (province of Messina, Italy) represent the oldest and largest skeletal collection yet found documenting human settlement of Sicily. The sample, attributed to the Late Epigravettian (between 14,000 and 10,000 years B.P.), consists of seven variously complete adult individuals (San Te…

Helminth parasites of the wolfCanis lupusfrom Latvia
2009
AbstractThirty-four wolves were collected between 2003 and 2008 from throughout Latvia and examined for helminths. A total of 17 helminth species were recorded: the trematodeAlaria alata(85.3%); the cestodesDiphyllobothrium latum(2.9%),Echinococcus granulosus(2.9%),Echinococcus multilocularis(5.9%),Mesocestoides lineatus(5.9%),Taenia crassiceps(8.8%),Taenia hydatigena(41.2%),Taenia (ovis) krabbei(8.8%),Taenia multiceps(47.1%),Taenia pisiformis(20.6%),Taenia polyacantha(11.8%),Taeniaspp. (8.8%); and the nematodesAncylostoma caninum(2.9%),Crenosoma vulpis(9.1%),Eucoleus aerophilus(36.4%),Pearsonema plica(41.4%),Trichinellaspp. (69.7%),Toxocara canis(5.8%), andUncinaria stenocephala(41.2%).Ala…
Could Road Safety Education (RSE) Help Parents Protect Children? Examining Their Driving Crashes with Children on Board
2021
Recent evidence suggests that driving behavior and traffic safety outcomes of parents may be influenced by the extent to which they receive information and education on road safety, as well as the fact of driving with their children on board, which may increase their risk perception. However, there are no studies specifically addressing the case of crashes suffered while driving with children. Hence, this study aimed to describe the relationship between road safety education-related variables and parents’ traffic safety outcomes while driving with children on board. For this cross-sectional study, data was retrieved from a sample composed of 165 Spanish parents—all of them licensed drivers—…
A novel compound heterozygous mutation in PYGM gene associated with McArdle’s disease
2022
McArdle's disease is an autosomal recessive glycogenosis due to mutation in the myophosphorylase gene (PYGM) resulting in a pure myopathy. The clinical onset typically occurs in childhood with cramps, myalgia, and intolerance to physical exercise, although late onset forms are also reported. We describe a case of a 17-year-old male complaining of cramps and myalgia following brief and intense exercise. The patient reported marked improvement in muscle fatigability few minutes after starting aerobic exercise. When he was a child, he had experienced few episodes of vomiting, nausea, and black colored urine following physical activity. Laboratory testings revealed high creatine kinase serum le…
Spontaneous cerebrospinal fluid rhinorrhea: A clinical and anatomical study
2010
Objectives/Hypothesis: Spontaneous nasal cerebrospinal fluid (CSF) fistula represents a rare clinical entity. The possible etiology and the localization of the rhinorrhea remain an ongoing clinical challenge. The purpose of this study was to evaluate the localization of spontaneous CSF fistula and to correlate it with anatomical studies. Study Design: Retrospective clinical study, prospective anatomical study. Methods: Twenty-nine patients with spontaneous CSF rhinorrhea were retrospectively studied, 10 males and 19 females. Ages ranged from 10 to 92 years (mean, 50 years). In addition, 48 human skulls from newborns to adults were examined for the postnatal development of the anterior and m…
Hypertonic saline solution and decompressive craniectomy for treatment of intracranial hypertension in pediatric severe traumatic brain injury.
2002
Experimental data 8 –11 and first clinical results in adults 12,13 suggest that hypertonic saline ( 1.0) may be highly effective in lowering ICP even when mannitol has lost its therapeutic potential after prolonged and repeated use. In children, only limited experience exists with the use of hypertonic saline solutions: a randomized prospective study in children with severe head injury compared the effects on ICP (increased to 15–20 mm Hg) of isotonic (0.9% NaCl) and hypertonic (3% NaCl) saline injections, demonstrating a beneficial effect of the hypertonic solution. 14 Another prospective randomized trial compared the effects of continuous infusion of either lactated Ringer’s solution (277…
