List common features of Shapiro syndrome
['Shapiro syndrome is defined as the constellation of periodic hypothermia and hyperhidrosis along with agenesis of the corpus callosum by Shapiro et al. in 1969.', 'Shapiro syndrome is a rare entity, comprising a triad of recurrent hypothermia, hyperhidrosis and congenital agenesis of the corpus callosum. ', 'We present a case of an 80 year old woman presenting with recurrent bouts of shivering, sweating and profound malaise, who sought medical attention because the frequency and severity of attacks worsened in her later years. MRI Brain demonstrated agenesis of the corpus callosum; a rigorous work-up excluded other causes for her symptomatology.', 'These findings imply that aberrant thermoregulation in Shapiro syndrome involves a number of structures remote from the callosal region.', "A 6-year-old girl previously diagnosed with Shapiro's syndrome was admitted to our hospital on several occasions during a 1-year period with complaints of altered consciousness, syncope, hypothermia and episodes of sweating.", "Hypermelatoninemia should be considered in patients with spontaneous periodic hypothermia and hyperhidrosis, and also in patients with Shapiro's syndrome.", 'We present a patient diagnosed with Shapiro syndrome without corpus callosum agenesis. A 4-year-old-girl was admitted to the hospital with complaints of sweating, cooling, and drowsiness that continued during the last week of her admission.', 'Postmortem data regarding the hypothalamic and surrounding areas from future cases of Shapiro syndrome and spontaneous periodic hypothermia would be of great interest.']
