encephalocele/fever

The aim of this study was to ascertain whether there is a period during early embryonic development of the rat that is particularly sensitive to hyperthermia. Pregnant Sprague-Dawley rats were partially immersed in a water bath at 43.5 degrees C until their core temperatures, monitored by a rectal

Hyperthermia as a human teratogen has been implicated as one cause for neurulation defects. To determine whether there is an association between early maternal hyperthermia (20 to 28 days' gestation) and isolated occipital encephalocele, record reviews were conducted for the period 1969 through 1979

We report the case of a 4.9-year-old boy with congenital hydrocephalus and obstruction of his shunt who just after the induction of anaesthesia suddenly developed generalized muscle rigidity that made intubation impossible. Because of temporary mydriasis the situation could hardly be differentiated

OBJECTIVE Chiari I malformation is a well-known disease involving caudal descent of the cerebellar tonsils and is generally considered to be a congenital condition. Acquired Chiari I malformations as a result of various causes are well described. An unusual case is reported in which regression of an

Nontuberculous causes of basilar meningitis are rare. This study presents the case of a male who developed fever and meningitis caused by Streptococcus pneumoniae. He developed multiple cranial nerve palsies and imaging findings consistent with basilar meningitis and ventriculitis. Computed

This report describes a 6-year-old Mexican boy presenting with inter alia, hitherto unrepaired cervical encephalocele and associated unilateral syndactyly. There was also ipsilateral clinodactyly of the thumb and possible polydactyly of the foot. In addition, there was unilateral fusion of the first

Sphenoidal encephalocele is a rare congenital anomaly. We report a case of sphenoidal encephalocele presenting with cerebral spinal fluid rhinorrhea. A 53-years-old man suffered recurrent fever and rhinorrhea. Computed tomography demonstrated a low density area extending from the left middle cranial

Hyperthermia is defined as a temperature of at least 1.5 degrees C over the normal core body temperature. It is a proven teratogen in animals and in humans. The type of defects induced by hyperthermia in experimental animals are: anencephaly/exencephaly, encephalocele, microphthalmia,

BACKGROUND Rocky Mountain spotted fever (RMSF) is a well-described, potentially lethal, tick-borne zoonotic infection and has very effective therapy. However, the diagnosis might not be made early enough, often leading to worse outcomes. OBJECTIVE Our aim was to discuss the diagnostic dilemmas

OBJECTIVE Anterior encephaloceles are rare congenital malformations. Most of the cases in the literature are reported from Southeast Asia. In India it is seen more frequently among manual laborers in the tea gardens of Assam. A brief background of the patients, clinical presentation, operative

Guinea pigs were exposed to hyperthermia for 1 hr once or twice on day 11, 12, 13, or 14 (E11-E14) of pregnancy. The mean rectal temperatures were elevated by 3.4 degrees C-4.0 degrees C. This treatment resulted in a marked elevation of rates of resorption and developmental defects in embryos

Hyperthermia was induced in ICR mice on day 8.5 of gestation by immersing them in hot water. Control mice were immersed in water at 38 degrees C for 15 min. In dams exposed to 42 degrees C for 12.5-15 min or to 43 degrees C for 7.5-10 min, externally malformed fetuses increased significantly and in

As maternal fever affects approximately 6-8% of early pregnancies, it is important to expand upon previous observations of an association between maternal fever and birth defects. We analyzed data from the National Birth Defects Prevention Study, a multistate, case-control study of major structural

We performed a retrospective study to assess the mechanisms and surgical strategies for transsellar transsphenoid encephalocele, a rare type of basal encephalocele. Its clinical presentations include multiple endocrine disturbances, visual deficits, cerebrospinal fluid rhinorrhea and dyspnea.

Immune responses occurring between the embryo and mother have been shown to influence the embryo's tolerance to teratogens, including chemical teratogens and diabetes-induced teratogenic insult. In this study, we tried to evaluate whether maternal immunostimulation alters the embryo's response to
