An in vivo study of skeletal muscle paralysis induced by intravenous barium chloride has been made in curarized and non-curarized rats. The influence of potassium and calcium chlorides, propranolol, ouabain, and prior adrenalectomy on the paralysis has also been studied. Paralysis is found to be due to a direct effect on skeletal muscle, and to correlate well with the development of hypokalaemi...

Mutations of skeletal muscle sodium channel a subunit (SCN4A) gene are associated with a group of allelic diseases, including periodic paralysis, paramyotonia congenital, sodium channel myotonia, and congenital myasthenic syndrome. Periodic paralysis is characterized by episodic attacks of flaccid weakness with the fluctuation of serum potassium, which are usually limited to skeletal muscles ow...

The aim of the present paper has been to explore the medieval evidence on miraculous healings of paralysis and to confront it with modern medical knowledge. Paralysis has been selected as a model for such a study and St. Bernardino of Siena (1380-1444) as a model of a saintly healer. Analyzed were the primary sources and modern literature. Paralysis was found to be among the most frequent disea...

Vocal cord paralysis is one of the most serious anesthetic complications related to endotracheal intubation. The practitioner should take extreme care, as bilateral vocal cord paralysis can obstruct the airway and lead to disastrous respiratory problems. There have been many papers on bilateral vocal cord paralysis after neck surgery, but reports on such a condition after lung surgery are very ...

Thyrotoxic induced hypokalemic periodic paralysis is a rare disorder that had been described in middle-aged men, predominantly Asians and Hispanics. This case presented with generalized weakness and hypokalemia after changing prescription for levothyroxine and starting prednisone to treat upper respiratory infection in a previously asymptomatic middle-aged Hispanic male. In this paper, we will ...

Among the first three manuscripts written in Persian, Akhawayni's Hidayat al-muta'allemin fi al-tibb was the most significant work compiled in the 10th century. Along with the hundreds of chapters on hygiene, anatomy, physiology, symptoms and treatments of the diseases of various organs, there is a chapter on sleep paralysis (night-mare) prior to description and treatment of epilepsy. The prese...

BACKGROUND The formalized neurological examination developed near the end of the 19th century, and clinicians searched for signs to differentiate weakness due to structural lesions of the central nervous system (organic paralysis) from weakness caused by hysteria. Joseph F. F. Babinski worked in the shadow of his mentor, Jean M. Charcot, until 1893, but then developed independent studies to exa...

Acute Flaccid Myelitis (AFM), a polio-like paralysis in children no older than 21, has recently reemerged and increasing numbers of such cases have been reported worldwide since 2012. Accurate and early diagnosis of this condition could help with better management of the disease. A 9- year- old girl with chief complaint of headache, fever and vomiting was subsequently affected by an acute...

Apart from eventration very little has been written about paralysis of the hemidiaphragm occurring without obvious cause. It is mentioned by Perry (1952), and Couch in 1953 reported 11 cases of paralysis of undetermined cause. The purpose of this paper is to report 10 cases of paralysis of the hemidiaphragm and five cases of partial paralysis (paresis) for which no cause was found during the pe...

Sleep paralysis is an experience of being temporarily unable to move or talk during the transitional periods between sleep and wakefulness: at sleep onset or upon awakening. Feeling of paralysis may be accompanied by a variety of vivid and intense sensory experiences, including mentation in visual, auditory, and tactile modalities, as well as a distinct feeling of presence. This chapter discuss...
