In addition, children with Kawasaki disease, with or without coronary artery complications, may have a more adverse cardiovascular risk profile, such as high blood pressure, obesity, and abnormal serum lipid profile.Gastrointestinal complications in Kawasaki disease are similar to those observed in Henoch–Schönlein purpura, such as: intestinal obstruction, colon swelling, intestinal ischemia, intestinal pseudo-obstruction, and acute abdomen.Eye changes associated with the disease have been described since the 1980s, being found as uveitis, iridocyclitis, conjunctival hemorrhage, optic neuritis, amaurosis, and ocular artery obstruction. It can also be found as necrotizing vasculitis, progressing into peripheral gangrene.The neurological complications per central nervous system  lesions are increasingly reported. The neurological complications found are meningoencephalitis, subdural effusion, cerebral hypoperfusion, cerebral ischemia and infarct, cerebellar infarction, manifesting with seizures, chorea, hemiplegia, mental confusion, lethargy and coma, or even a cerebral infarction with no neurological manifestations. Other neurological complications from cranial nerve involvement are reported as ataxia, facial palsy, and sensorineural hearing loss. Behavioral changes are thought to be caused by localised cerebral hypoperfusion, can include attention deficits, learning deficits, emotional disorders (emotional lability, fear of night, and night terrors), and internalization problems (anxious, depressive or aggressive behavior). Causes
The specific cause of Kawasaki disease is unknown. A plausible explanation is that it may be caused by an infection that triggers an inappropriate immunologic cascade in a small number of genetically predisposed children. The pathogenesis is complex and incompletely understood. Various explanations exist. (See #Classification)
Circumstantial evidence points to an infectious cause.
Diet
Studies indicate that dietary patterns may affect development of BPH, but further research is needed to clarify any important relationship. Studies from China suggest that greater protein intake may be a factor in development of BPH. Men older than 60 in rural areas had very low rates of clinical BPH, while men living in cities and consuming more animal protein had a higher incidence. On the other hand, a study in Japanese-American men in Hawaii found a strong negative association with alcohol intake, but a weak positive association with beef intake. In a large prospective cohort study in the US (the Health Professionals Follow-up Study), investigators reported modest associations between BPH (men with strong symptoms of BPH or surgically confirmed BPH) and total energy and protein, but not fat intake. There is also epidemiological evidence linking BPH with metabolic syndrome (concurrent obesity, impaired glucose metabolism and diabetes, high triglyceride levels, high levels of low-density cholesterol, and hypertension). Degeneration
Benign prostatic hyperplasia is an age-related disease. Misrepair-accumulation aging theory suggests that development of benign prostatic hyperplasia is a consequence of fibrosis and weakening of the muscular tissue in the prostate. The muscular tissue is important in the functionality of the prostate, and provides the force for excreting the fluid produced by prostatic glands. However, repeated contractions and dilations of myofibers will unavoidably cause injuries and broken myofibers. Myofibers have a low potential for regeneration; therefore, collagen fibers need to be used to replace the broken myofibers.
