1/6. sneezing as a cause of acute angle-closure glaucoma.We report the case of a patient who had an attack of acute angle-closure glaucoma precipitated by sneezing, probably as a result of a sudden increase in venous back pressure. This young woman had a history of allergic sinusitis.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
2/6. Sinus thrombosis after a jump from a small rock and a sneezing attack: minor endothelial trauma as a precipitating factor for cerebral venous thrombosis?Cerebral venous thrombosis (CVT) associated with minor or trivial head trauma has only been described in a few cases so far. We report two patients who developed CVT after a sudden intracranial pressure increase and head acceleration. A 49-year-old woman jumped from a small rock, 1 m in height, and developed instantaneous occipital headaches. magnetic resonance imaging (MRI) confirmed confluens sinuum thrombosis. risk factors consisted of smoking and oral contraceptives. Our second patient, an 18-year-old woman, experienced instantaneous headaches after a sneezing attack. Superior sagittal and right-sided transverse sinus thrombosis were confirmed by venous computed tomography angiography. She took oral contraceptives as an additional risk factor. In about 20% of CVT cases the cause remains unclear. As minor head trauma may not have been recognized during history taking, this may represent a so far under-recognized precipitating factor for CVT.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
3/6. Acute aortic dissection provoked by sneeze: a case report.The response of the abdominal viscera and the contraction of the intercostal muscles during the respiratory phase of sneezing increases intrathoracic pressure, which may lead to several complications. However, there are no reports in the literature concerning aortic dissection after sneezing. We report a patient in whom the development of dissection was secondary to sneezing, although hypertension was present as a risk factor, and we discuss the relationship between sneezing and aortic dissection. To our knowledge, this is the first report of aortic dissection provoked by sneezing in the literature.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
4/6. Suppressed sneezing as a cause of hearing loss and vertigo.Two cases of inner ear injury caused by suppressed sneezing are described. One patient experienced vestibular symptoms in the form of reflexogenic vertigo that was relieved by surgical section of the tensor tympani tendon. The other patient had a sudden severe permanent sensorineural hearing loss. It is proposed that the aerodynamic pressure increase associated with suppressed sneezing is transmitted via the eustachian tube to cause an implosive fistula of either the round or oval window with injury to the membranous labyrinth.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
5/6. The "innocent" cough or sneeze: a harbinger of serious latex allergy in children during bladder stimulation and urodynamic testing.latex hypersensitivity is a well documented phenomenon most commonly reported in children with spina bifida during surgical and other procedures involving exposure to latex. IgE-mediated immediate hypersensitivity to the protein or polypeptide components of latex may be severe and manifest as generalized anaphylaxis or cardiovascular collapse. Of 17 children with spina bifida undergoing transurethral electrical bladder stimulation we identified 5 with latex allergy 3 to 9 years old. All 5 patients were noted to manifest sneezing or a cough several minutes before the development of a generalized hypersensitivity reaction, which in several patients progressed to bronchospasm. Subsequent investigations have shown that the inciting agent was the rectal pressure balloon made from a latex finger cot. Recognition of the earliest manifestations of latex hypersensitivity is an important clinical tool in the prevention of severe allergic reactions.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
6/6. 'Sneeze syncope', basilar invagination and Arnold-Chiari type I malformation.syncope precipitated by sneezing in an adult male associated with an Arnold-Chiari type I malformation and basilar invagination presents a clinical problem in the differential diagnosis and pathological anatomy of Valsalva-related syncope. An abnormally acute clivoaxial angle, small foramen magnum, and type I arnold-chiari malformation appear to be a combination of features intolerant of Valsalva-induced changes in cerebral volume, brain-stem position, CSF fluid dynamics, or blood vessel relationships. Proposed mechanisms of pressure transmission to the area of intracranial pathology are discussed.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
