Potassium deficiency accelerates the secretion of HI ions by the kidney; in consequence the net ex-cretion of acid (ammonia and titratable acid-bi-carbonate) into the urine and the capacity to re-absorb filtered HCO3-are increased (1-7). Although the precise mechanism involved has not been identified, Berliner, Kennedy, and Orloff (8), on the basis of the demonstrated reciprocal relationship be...

background fractures of the knee account for about 6% of all trauma admissions. while its management is mostly focused on fracture treatment, it is not the only factor that defines the final outcome. objectives this study aimed to study objective and subjective outcomes after proximal tibial versus distal femoral fractures in terms of knee instability and health-related quality of life. patient...

Slowing of transit through the proximal small intestine by fat in the distal gut is termed the ileal brake. Intravenous naloxone, an opioid receptor antagonist, abolished the fat-induced ileal brake, suggesting that an endogenous opioid pathway may be involved in this response. To test the hypothesis that slowing of intestinal transit by fat in the distal half of the gut depends on an opioid pa...

Background & Aims: Distal leg, ankle and foot injuries are relatively common; and because of lack of soft tissue and poor blood supply in these areas, one of the common problems in these patients is soft tissue necrosis. Exposed orthopedic implants can be used as open reduction internal fixator (ORIF) in these regions. Methods: During 2013-2014, 14 patients (11 men and 3 women) with a mean age ...

BACKGROUND Atrioventricular (AV) nodal reentrant tachycardia is classically described as a reentrant rhythm entirely contained within the compact AV node. Although the concepts of longitudinal dissociation of two intranodal pathways and a distal common pathway are accepted, the proximal portion of the circuit remains undefined. Current reports suggest that the two pathways may be separable by a...
