Sleep Disturbances During Shift Work.

Around 21% of workers reported working on shifts in 2017, and consequently, shift workers experience multiple sleep disturbances such as excessive sleepiness, insomnia, sleep deprivation, and social jet lag. These eventually lead to shift work disorder or exacerbation of other sleep disorders such as insomnia, obstructive sleep apnea, restless legs syndrome, and nonrapid eye movement parasomnia. Despite multiple interventions and guidelines, poor compliance to treatment is often encountered due to temporary relief of sleep disturbances provided by the treatment. Hence there is a need for comprehensive evaluation of those individuals who need to be awake during the night and asleep during the day.

Tumoral calcinosis in secondary hyperparathyroidism

@#<p style="text-align: justify;"><strong>OBJECTIVE:</strong> To  report  a  case  of  tumoral  calcinosis  from  secondary hyperparathyroidism  and  to describe its surgical management.<br /><strong>METHODS:</strong><br /><strong> Design:</strong> Case Report<br /> <strong>Setting:</strong> Tertiary Public University Hospital<br /> <strong>Patient:</strong> One<br /><strong>RESULTS:</strong> A 34-year-old woman presented with progressively-enlarging bilateral upper extremity masses. Diagnostic tests revealed hyperfunctioning parathyroid glands. The patient underwent subtotal  parathyroidectomy,  right  thyroid  lobectomy  with  isthmusectomy,  and  transcervical thymectomy.    Follow-up  revealed  marked  decrease  in  parathyroid  hormone,  and  progressive resolution of the tumoral calcinosis.<br /><strong>CONCLUSION:</strong> Subtotal  parathyroidectomy  and  transcervical  thymectomy  have  a  role  in  the management  of  tumoral  calcinosis,  and  in  this  case  led  to  excellent  post-operative  results. The rare  presentation  of  secondary  hyperparathyroidism  and  intervention  in  this  patient  may  have potential lessons for future management of similar cases.</p>
