However, according to the nationwide inpatient sample from the United States, the incidence of severe sepsis increased from 200 per 10,000 population in 2003 to 300 cases in 2007 for population aged more than 18 years. The incidence rate is particularly high among infants, with an incidence of 500 cases per 100,000 population. Mortality related to sepsis increases with age, from less than 10% in the age group of 3 to 5 years to 60% by sixth decade of life. The increase in the average age of the population, alongside the presence of more people with chronic diseases or on immunosuppressive medications, and also the increase in the number of invasive procedures being performed, has led to an increased rate of sepsis. History
The term "σήψις" (sepsis) was introduced by Hippocrates in the fourth century BC, and it meant the process of decay or decomposition of organic matter. In the eleventh century, Avicenna used the term "blood rot" for diseases linked to severe purulent process. Though severe systemic toxicity had already been observed, it was only in the 19th century that the specific term – sepsis – was used for this condition. The terms "septicemia", also spelled "septicaemia", and "blood poisoning" referred to the microorganisms or their toxins in the blood. The International Statistical Classification of Diseases and Related Health Problems (ICD) version 9, which was in use in the US until 2013, used the term septicemia with numerous modifiers for different diagnoses, such as "Streptococcal septicemia".
Abdominal migraine is a variant type of migraine. It primarily affects children, and is rare in adults. It mainly causes episodes of abdominal pain without an accompanying headache. It is poorly understood. It is difficult to confirm the diagnosis, as periumbilical abdominal pain has an extensive differential diagnosis. It may be treated with analgesia in some patients, and other medications. Avoiding triggers can prevent an episode of abdominal migraine. Signs and Symptoms
Symptoms of abdominal migraine may include:

Abdominal pain
Nausea
Vomiting
Headache
Photosensitivity
Loss of appetite
PallorThese occur in distinct episodes. This can have a significant effect on day-to-day life. It usually does not occur with a headache. Body mass index is usually unaffected, and physical development is normal. Causes
Common migraine triggers may trigger abdominal migraines. Psychological stress (such as from school), a change in location (such as travel), changes to sleep, and exercise when this is not wanted, may all cause abdominal migraine. Pathophysiology
Abdominal migraine is poorly understood. Diagnosis
As with other types of migraines, there is no diagnostic test to identify abdominal migraines. Diagnosis is based on symptoms, a family history of migraines, and eliminations of other possible causes. It can take time before a diagnosis is made, as symptoms are not specific to abdominal migraine.Diagnostic criteria from the International Classification of Headache Disorders are:

A. At least 5 attacks fulfilling criteria B-D.
B.
