Hostility  is seen as form of emotionally charged aggressive behavior. In everyday speech it is more commonly used as a synonym for anger and aggression. It appears in several psychological theories. For instance it is a facet of neuroticism in the NEO PI, and forms part of personal construct psychology, developed by George Kelly. Hostility/hospitality
For hunter gatherers, every stranger from outside the small tribal group was a potential source of hostility. Similarly, in archaic Greece, every community was in a state of hostility, latent or overt, with every other community - something only gradually tempered by the rights and duties of hospitality.Tensions between the two poles of hostility and hospitality remain a potent force in the 21st century world. Us/them
Robert Sapolsky argues that the tendency to form in-groups and out-groups of Us and Them, and to direct hostility at the latter, is inherent in humans. He also explores the possibility raised by Samuel Bowles that intra-group hostility is reduced when greater hostility is directed at Thems, something exploited by insecure leaders when they mobilise external conflicts so as to reduce in-group hostility towards themselves. Non-verbal indicators
Automatic mental functioning suggests that among universal human indicators of hostility are the grinding or gnashing of teeth, the clenching and shaking of fists, and grimacing. Desmond Morris would add stamping and thumping.The Haka represents a ritualised set of such non-verbal signs of hostility.
The incidence of these cysts are possibly linked to boys who are exposed to diethylstilbestrol, an estrogen medication, while in the fetus.Although the evidence and information for incidence of spermatoceles in children is lacking, there are general management guidelines for caregivers who may encounter spermatoceles in their children. Epididymal cysts are typically benign in nature. However, caregivers should take note of any discomfort and symptoms in children, including but not limited to, erythema, scrotal edema or swelling. Epididymal cysts appear in approximately 70% of boys who present as asymptomatic. The diagnosis of epididymal cysts in children can be discovered upon physical examination and eventually confirmed via ultrasound. Treatment
Small cysts as well as asymptomatic larger cysts are better left alone and carefully observed. However, treatment can be considered if the cysts are causing discomfort/pain, enlarging in size, or per patient request. There are a few different treatment options, ranging in levels of invasiveness. Medications
Certain drugs such as oral analgesics or anti-inflammatory medications can be taken by mouth to decrease spermatocele-related symptoms such as pain and/or swelling. At the moment, there is no medication that can inhibit the production of a spermatocele or cure it. Common medications recommended by doctors are acetaminophen (Tylenol) that can treat pain. To treat the inflammation and pain, non-steroidal anti-inflammatory drugs (NSAIDs) are recommended such as ibuprofen (Motrin, Advil), naproxen (Aleve), and others. Antibiotics may also be prescribed in cases where risk of infection and discomfort is indicated.
