Febrile neutropenia or neutropenic fever is a defined as a single oral temperature value of ≥ 38.3 C (101 F) or a temperature ≥ 38 C (100.4 F) for ≥ 1 hour, with an absolute neutrophil count (ANC) < 1500 cell/microliter. [1] In case of severe neutropenia, the ANC is < 500 cell/microliter. [1]
On the other hand, a "normal" temperature may be a fever, if it is unusually high for that person; for example, medically frail elderly people have a decreased ability to generate body heat, so a "normal" temperature of 37.3 °C (99.1 °F) may represent a clinically significant fever.
Brazilian purpuric fever (BPF) is an illness of children caused by the bacterium Haemophilus influenzae biogroup aegyptius which is ultimately fatal due to sepsis. BPF was first recognized in the São Paulo state of Brazil in 1984.
f) Relapsing fever. Remittent fever is a type or pattern of fever in which temperature does not touch the baseline and remains above normal throughout the day. Daily variation in temperature is more than 1°C in 24 hours, which is also the main difference as compared to continuous fever. [1] [2] [3] Fever due to most infectious diseases is ...
Rheumatic fever primarily affects children between ages 5 and 17 years and occurs approximately 20 days after strep throat. In up to a third of cases, the underlying strep infection may not have caused any symptoms. [citation needed] The rate of development of rheumatic fever in individuals with untreated strep infection is estimated to be 3%.
The 1918 pandemic triggered frenzied search for its cause, although most deaths were via lobar pneumonia, already attributed to pneumococcal invasion. In London, pathologist with the Ministry of Health, Fred Griffith in 1928 reported pneumococcal transformation from virulent to avirulent and between antigenic types —nearly a switch in species ...
This makes invasive cancer the leading cause of death in the developed world and the second leading in the developing world. [25] Over half of cases occur in the developing world. [25] Deaths from cancer were 5.8 million in 1990. [211] Deaths have been increasing primarily due to longer lifespans and lifestyle changes in the developing world. [25]
In 2013 CAD was the most common cause of death globally, resulting in 8.14 million deaths (16.8%) up from 5.74 million deaths (12%) in 1990. [26] The risk of death from CAD for a given age has decreased between 1980 and 2010 especially in developed countries. [39] The number of cases of CAD for a given age has also decreased between 1990 and ...
