There are some reports about hypoxemia related to hypopituitarism. However, little is known about the relationship between growth hormone deficiency (GHD) and hypoxemia.A 23-year-old female presented with severe hypoxemia after the operations of BACKGROUND
Craniopharyngioma is a benign tumor, but recurrences are common and prognosis is poor. The pathologic mechanism underlying the high recurrence is still unknown.
OBJECTIVE
We hypothesized that there are hypoxic microenvironments within craniopharyngiomas and hypoxia inducible factor-1
OBJECTIVE
In craniopharyngiomas, cystic growth causes pressure on vital structures of the adjacent brain, leading to significant morbidity. However, the molecular pathogenesis of this cyst formation remains unknown. Carbonic anhydrase IX (CA IX) is a tumor-associated, hypoxia-inducible enzyme, which
Hypothalamic obesity is often complicated in patients with craniopharyngioma due to hypothalamic damage by the tumor itself, treatment modalities, and associated multiple pituitary hormone deficiency. Hypothalamic obesity causes secondary diseases such as nonalcoholic fatty liver disease (NAFLD) and
Cancer cells bear various metabolic alterations in order to survive and progress. Neoplastic cells rewire their metabolic pathways for fermentation of glucose and production of more lactate. Microenvironment acidification is a common feature of many neoplastic lesions. In other words, A case of central pontine myelinolysis (CPM) following rapid correction of hyponatremia was reported and literatures were reviewed. The case was 61-year-old nonalcoholic female who had taken an operation of craniopharyngioma 23 years ago. Fifteen years later, she received re-operation for the
Carbonic anhydrases (CAs) are zinc-containing metalloenzymes that participate in the regulation of pH homeostasis in addition to many other important physiological functions. Importantly, CAs have been associated with neoplastic processes and cancer. Brain tumors represent a heterogeneous group of
In systemic cancers, increased hemolysis leads to extracellular hemoglobin (HB), and experimental studies have shown its provoking role on tumor growth and metastasis. However, investigations have shown that HB chains presented by tumor vascular pericytes or serum protein complexes of HB could also
