The pattern of postoperative pyrexia in Khartoum was prospectively studied in 260 patients who underwent a variety of surgical operations. Ninety four patients (36.1%) developed postoperative pyrexia. The commonest causes of pyrexia encountered were wound sepsis (10%), malaria (9.6%) and respiratory tract infection (7.3%). Less frequent causes were urinary tract infection, thrombophlebitis, intra-abdominal sepsis and deep vein thrombosis. In 14.6% of the patients, the cause of pyrexia was undetermined. The risk factors for postoperative pyrexia were the patient's age, diabetes mellitus, obesity, preoperative chest infection, smoking, duration of surgery, operator's surgical experience and urethral catheterisation. The postoperative pyrexia was associated with 7.4% mortality rate which was due to intra-abdominal sepsis and pulmonary embolism. The incidence of postoperative pyrexia can be minimised by adequate preoperative preparation, meticulous surgical technique and good postoperative care.

Lower respiratory tract infections caused by bacteria are a major cause of death in humans irrespective of sex, race, or geography. Indeed, accumulated data indicate greater mortality and morbidity due to these infections than cancer, malaria, or HIV infection. Successful recognition of, followed by an appropriate response to, bacterial pathogens in the lungs is crucial for effective pulmonary host defense. Although the early recruitment and activation of neutrophils in the lungs is key in the response against invading microbial pathogens, other sentinels, such as alveolar macrophages, epithelial cells, dendritic cells, and CD4(+) T cells, also contribute to the elimination of the bacterial burden. Pattern recognition receptors, such as Toll-like receptors (TLRs) and nucleotide-binding oligomerization domain-like receptors, are important for recognizing and responding to microbes during pulmonary infections. However, bacterial pathogens have acquired crafty evasive strategies to circumvent the pattern recognition receptor response and thus establish infection. Increased understanding of the function of TLRs and evasive mechanisms used by pathogens during pulmonary infection will deepen our knowledge of immunopathogenesis and is crucial for developing effective therapeutic and/or prophylactic measures. This review summarizes current knowledge of the multiple roles of TLRs in bacterial lung infections and highlights the mechanisms used by pathogens to modulate or interfere with TLR signaling in the lungs.
