With a growing population of people living with and beyond cancer, a larger portion of cancer research has shifted to ensuring that these people not only survive but survive well, and so supportive oncology has emerged as a critical component of modern cancer care. However, research and advancements in supportive care strategies have largely centered around symptom management, without an appreciation for the physiological mechanisms underlying the symptom. By placing a greater emphasis on understanding the pathophysiological mechanisms that lurk beneath the symptom in supportive care and survivorship research, superior symptom control and greater improvements to quality of life, through the development of targeted interventions, can be achieved.

These neurodevelopmental processes are unique to the paediatric brain and are facilitated by augmented rates of neuroplasticity and expanded neural stem cell populations within neurogenic niches. However, given the immaturity of the developing central nervous system, innate protective mechanisms such as neuroimmune and antioxidant responses are functionally naïve which results in periods of heightened sensitivity to neurotoxic insult.

Percutaneous liver biopsy (PLB) is a valuable diagnostic tool. Complication rates vary depending on the technique used, experience of the physician, number of passes, bleeding parameters and other factors. Hemorrhage is a common complication after PLB and can present as intraperitoneal bleeding, intrahepatic or subcapsular hematoma, or rarely as hemobilia.

Thalamic relay neurons have homogeneous, adult-like firing properties and similar morphology by 12 days postnatally (PN 12). Parafascicular (Pf) neurons have a different morphology compared with typical thalamic relay neurons, but the development of their electrophysiological properties is not well studied. Intracellular recordings in PN 12-50 Pf neurons revealed several heterogeneous firing patterns different from those in thalamic relay neurons.

Symptoms include abdominal pain, nausea, vomiting, constipation, cystic abdominal mass, and high-pitched bowel sounds. Abdominal x-ray photography is often diagnostic, revealing a dilated cecum with a single fluid level and distended loops of small bowel.

Herein, we have presented yet another use for the interposition polytetrafluoroethylene graft conduit, based on physiologically sound principles and a now proved successful outcome, namely as a surgical alternative for the patient with a hemodynamically unstable hemodialysis fistula resulting in arterial insufficiency. Poiseuille's Law regarding flow of liquids through a tube supports the concept on which our interposition graft is based: v = pi X P X R4/8 X 1 X n where v is the volume escaping per second, P the difference of pressure at the ends of the tube, R its radius, l the length of the tube, and n the coefficient of viscosity.
