Primary hyperparathyroidism (PHPT) remains a relatively underdiagnosed disease in developing countries. The aim of this study was to assess the demographic, pathological, biochemical, and surgical characteristics of patients with primary hyperparathyroidism in a university hospital department of otolaryngology in eastern Algeria. We performed a retrospective analysis of the records of 62 patients operated in our department for primary hyperparathyroidism between January 2002 and December 2013. The mean age was 47.7 ± 15 years with a female preponderance (88.7%). The mode of discovery was during a biological assessment for bone syndrome in 42% of cases. The mean calcemia was 2.92 ± 0.6 mmol/L, and the intact serum parathyroid hormone was 867.78 ± 954.50 pmol/L. A total of 54.8% of patients had bilateral neck exploration, and 45.2% had minimally invasive open parathyroidectomy. Postoperative complications were dominated by severe hypocalcemia and hungry bone syndrome. The diagnosis of primary hyperparathyroidism in our country is late, and management is often performed after the appearance of bone and renal complications.

To cope with COVID-19 pandemic control precautions, many surgical residency programs have adopted a Declared Health Emergency (DHE) rotation to minimize exposure to the COVID-19. We evaluated the experience and educational value of virtual education activities by reviewing the perceptions of the DHE rotation participants through survey questionnaire analysis. Participants of the DHE rotation virtual educational activities were asked to complete a survey questionnaire describing their perception and experienc
