A family with hypercalcemia in four members is reported. The proband, a newborn girl presenting with inadequate sucking due to muscle hypotonia, marked thoracic deformity due to decalcification, hypercalcemia, and hypophosphatemia, suffers from cerebral damage due to hypoxia despite successful total
We measured contractile force of ventricular strips form the turtle Chrysemys picta bellii exposed to 1 h of combined anoxia and acidosis (pH 7.0) at 20 degrees C. Strips either beat spontaneously (self-paced) or in response to electrical stimulation (paced at 12, 24, or 36 beats/min). Tissue
Therapeutic hypothermia (TH) is provided to newborns with moderate to severe hypoxic-ischemic encephalopathy (HIE) to improve survival and long-term neurodevelopmental outcomes. Although the benefits certainly outweigh the risks associated with therapeutic hypothermia, it is important to be mindful
It has been suggested that cyclic nucleotides (cAMP and cGMP) participate in the regulation of cardiac contractility and glycolysis. In the present study, this possible involvement was examined in spontaneously beating rat atria during hypoxia (50% oxygen saturation). Thirty seconds after reduction
A 38-year-old woman with megakaryoblastic chronic myelocytic leukemia (CML) crisis developed recurrent episodes of severe hypercalcemia, manifested by nausea and vomiting and later by dyspnea and hypoxia. The levels of serum parathyroid hormone and serum and urine cyclic AMP were normal. Autopsy
The pulmonary artery responses in the isolated whole-blood perfused canine lung to ionized calcium ([Ca++]) were quantified over a range of hypercalcemia and hypocalcemia values ([Ca++] = 0.23-1.88 mM) under conditions of controlled pulmonary blood flow and constant mean aortic and left atrial
Heart rate (f(H)) of the anoxia-tolerant freshwater turtle (Trachemys scripta) during prolonged anoxia exposure is 2.5- to 5-times lower than the normoxic rate, but whether alterations in blood composition that accompany prolonged anoxia contribute to this bradycardia is unknown. We examined how
Parathyroid hormone-related protein (PTHrP) expressed by human cancer cells enhances tumor cell growth and metastasis in vivo and it is considered as the major factor responsible for humoral hypercalcemia of malignancy. Hypoxia is a widespread feature of most solid tumors. Here, we studied the
BACKGROUND
Most patients with advanced breast cancer develop bone metastases, which cause pain, hypercalcemia, fractures, nerve compression and paralysis. Chemotherapy causes further bone loss, and bone-specific treatments are only palliative. Multiple tumor-secreted factors act on the bone
Acexamic acid is currently used to avoid pulmonary fibrosis in patients treated with bleomycim. It seems to be equally effective to prevent pulmonary fibrosis in adult respiratory distress syndrome. The complications of this therapy are hypercalcemia and hypernatremia.
We describe a patient who had developed hypercalcemic crisis, with altered mental status and renal failure, one year following aggressive corticosteroid-therapy for lupus nephritis. Her disease relapsed after successful live-related kidney transplantation 11 years ago. She had normal parathyroid
After description of the central-nervous signs due to hypoglycemia, hypoxia, hypo- and hypercalcemia there are discussed several internal diseases with prominent neurologic symptoms like endocrine disorders of thyroid, adrenal and pituitary gland, malignant diseases especially regarding the
Subcutaneous fat necrosis of the newborn (SFN) is an uncommon disease that affects newborns who have suffered from tissue hypoxia during or following delivery. This disease appears during the first weeks of life. It consists of indurate, erythematous or purple-erythematous nodules and plaques in the
Painted turtles (Chrysemys picta) survive months of anoxic submergence, which is associated with large changes in the extracellular milieu where pH falls by 1, while extracellular K+, Ca++, and adrenaline levels all increase massively. While the effect of each of these changes in the extracellular
An 18-month-old infant with aleukemic monocytic leukemia and osteoclastic bone resorption demonstrated in the pelvis, vertebral bodies, and ribs developed severe refractory hypercalcemia. Bilateral interstitial pulmonary radiopacities developed rapidly, accompanied by hypoxemia and hypercapnea. Von
