What Causes Vomiting?

Discussion Regurgitation is a passive expulsion of ingested material out of the mouth. It is a normal part of digestion for ruminants such as cows and camels. Nausea is an unpleasant abdominal perception that the person may describe as feeling ill to the stomach, or feeling like he/she is going to vomit. Anorexia is frequently observed. Nausea is usually associated with decreased stomach activity and motility in the small intestine. Parasympathetic activity may be increased causing pale skin, sweating, hypersalivation and possible vasovagal syndrome (hypotension and bradycardia). Retching or dry heaves is when there are spasmodic respiratory movements against a closed glottis. This often occurs just before emesis. Emesis, vomiting or vomition is when stomach (sometimes small intestine also) contents are propelled up the esophagus and out the mouth. It is composed of three basic parts: A deep breath is taken, the glottis closed to prevent aspiration into the lungs, while the larynx is raised which helps to open the upper esophageal sphincter. There is a decrease in respiration. The soft palate also closes to try to protect the posterior nares. The pylorus also contracts. The diaphragm contracts downward sharply which creates negative thoracic pressures. This also assists the opening of the lower esophageal sphincter and the esophagus itself. As the diaphragm contracts, the abdominal wall muscles vigorously contract which increases the intragastric pressure. As the pylorus ...

Authors: Concha-Del Rio LE, Uribe-Reina P, De-La-Torre A Abstract Allergy to steroids is an uncommon and harmful condition that leads to a decrease in treatment options and increase in morbidity due to the suboptimal disease control. It can manifest as an immediate response or a delay manifestation. Worsening of underlying condition and not treatment response can indicate corticosteroids hypersensitivity as well. Despite its low prevalence, all clinicians should be aware of this condition and know the treatment options. This narrative review attempts to update information about corticosteroid allergy and we present...

This study aimed to investigate the prognostic value of PNR and PWR in acute ischemic stroke patients treated with EVT. METHODS: Poor functional outcome was defined as Modified Rankin Scale (mRS) of 3-6 at 3 months, Symptomatic intracranial hemorrhage (sICH) was diagnosed based on CT scan and classified according to the criterial of Heidelberg Bleeding Classification. Binary logistical regression was used to analyze the relationship of PWR, PNR with functional outcome and symptomatic intracranial hemorrhage (sICH). RESULTS: Patients with good prognosis had higher PNR and PWR value (29 vs. 24, P=0.002) (22 vs. 19, P...

This study investigates possible race- and ethnicity-related disparities in the treatment of acne, atopic dermatitis, and psoriasis of newly approved treatments as well as existing therapies. METHODS: Aggregate level data was collected from patient medical records between 2013 and 2018. The odds ratio of patients who had been prescribed treatments for acne, atopic dermatitis, and psoriasis per racial and ethnic group were calculated using a 95% confidence interval after applying Bonferroni correction to account for multiple comparisons. RESULTS: Black patients with acne had statistically significant (p
