Case ReportsA case of severe, irreversible hypocalcemia after one dose of pamidronate administered for hypercalcemia of malignancy.
This is a case report of a patient who developed severe, irreversible hypocalcemia after receiving one dose of pamidronate 90 mg for hypercalcemia of malignancy. Hypocalcemia is a known risk of bisphosphonate treatments, but the incidence of severe hypocalcemia is rare, and the risk factors are well established. ⋯ Furthermore, there is unawareness of prevalence of vitamin D deficiency in cancer patients, especially in those with advanced cancer, which may lead to inadvertent, severe hypocalcemia from bisphosphonate treatment. The objective of this case report is to bring awareness to the risk of severe hypocalcemia in patients with hypercalcemia of malignancy and the high prevalence of unrecognized vitamin D deficiency in cancer patients.

Case ReportsNiraparib - A promising drug with hematological toxicity.
Ovarian cancer is the second most common and the most lethal gynecological malignancy in the western world. Unfortunately, there are lack of methods for early screening and diagnosis of the disease. Because of this, most of the cases are diagnosed at an advanced stage and have poor prognosis. ⋯ We are reporting two cases of Grade III/IV neutropenia and thrombocytopenia in patients treated with niraparib in our institution. Unfortunately, one of the patients succumbed to septic shock secondary to right lower lobe pneumonia while severely neutropenic. The second patient's blood counts improved after discontinuing the medication and with supportive transfusions during the hospitalization.
