Hypertrophic pyloric stenosis [PDF]

, 2013
A 6-week old baby was brought to A&E by her parents, after a 3 week history of frequent vomiting, not tolerating feeds, and weight loss. She was well for the first 3 weeks of life, before she stopped tolerating any feeds. Despite several changes with the

Cerebral oxygen extraction across different exercise intensities: Role of arterial PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_2}}}$

Experimental Physiology, EarlyView.
Abstract Stability in cerebral oxygen extraction fraction (OEF) is typically determined by alterations in cerebral blood flow (CBF). At rest, arterial partial pressure of carbon dioxide (PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_2}}}$) and OEF exhibit a strong inverse relationship owing to the powerful influence of PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_2}}}$

Assessment of Blood pH and pCO2 as Predictors of Febrile Seizures in Paediatric Patients: A Cross-sectional Study [PDF]

Journal of Clinical and Diagnostic Research
Introduction: Febrile seizures commonly occur in the age group of six months to five years. Hypocarbia and alkalosis are known to enhance neuronal excitability and promote epileptiform activity.

AltitudeOmics : Resetting of Cerebrovascular CO2 Reactivity Following Acclimatization to High Altitude. [PDF]

, 2015
Previous studies reported enhanced cerebrovascular CO2 reactivity upon ascent to high altitude using linear models. However, there is evidence that this response may be sigmoidal in nature.

Cerebrovascular regulation during heat stress

Experimental Physiology, EarlyView.
Abstract Given that the brain is a highly metabolic organ and is enclosed by the skull, effective regulation of cerebral blood flow (CBF), not only for oxygen and nutrients supply but also as a means of convective heat exchange, is critical for preventing excessive elevations in brain temperature.

Early acclimatization to high altitude: Acid–base and fluid balance dynamics during the first 2 days at 3100 m

Experimental Physiology
Immediate responses to hypoxia at high altitude are hyperventilation and successive respiratory alkalosis. Alkalosis, in turn, can affect cerebrospinal fluid pH and ventilatory control. The kidneys compensate metabolically for respiratory alkalosis.

Fetal Metabolic Alkalosis Resulting from Maternal Vomiting

American Journal of Perinatology Reports
We describe a pregnant patient with severe compulsive water ingestion and vomiting that lead to metabolic alkalosis and preterm delivery. A 21-year-old patient was hospitalized multiple times throughout pregnancy for symptoms initially thought to be ...

Brain strain: Blood flow and metabolism in environmental extremes

Experimental Physiology, EarlyView.
Abstract This narrative review compares and contrasts the most commonly encountered environmental stressors on human cerebrovascular functioning. From high altitude and space, extreme apnoea, heat and cold stress, the impact of these stressors on the regulation of cerebral blood flow (CBF) and oxygen metabolism (CMRO2${\mathrm{CM}}{{\mathrm{R}}_ ...
