Decelerating the aging process.
Diseases whose incidence and prevalence are increased in the elderly and whose cytopathology, hormones, and immunogenesis differ, generally are included in the field of geriatrics. These conditions may be precipitated or accelerated in quantity or type by a wide variety of genetic and environmental factors. Chronological and progressive deterioration of selected cells, organs, and tissues, and their functions may occur without major specific pathology. These processes are referred to as senescence and its study, is gerontology.Geriatrics includes senility and diseases of the elderly. Terms associated with gerontology include benign agism or senescence, as a normal consequence of the aging processes common to all biological forms of life.The age period, 65 to 85 years, does not necessarily imply senility, but the normal chronological aging of an individual in an industrialized, urbanized society. This paper emphasizes recommendations for deceleration of the normal aging process.
Clinical myiasis.
Human clinical myiasis is a rare entity in temperate zones, but it is of frequent occurrence among indigenous populations in tropical countries. The physician in practice in temperate zones, especially in urban areas, will generally see cases in those who have returned from rural travel or duty tours in tropical countries.Temperate zone physicians by training and clinical services frequently are not prepared to accurately diagnose and treat cases of myiasis. This paper is a report of experiences and records of cases of myiasis and is intended to alert temperate zone physicians to the possibilities of myiasis among a limited number of their patients.
International health--a traveler's alert.
The human population of the earth is estimated to be approximately four billion people, the majority of whom live in developing countries of Africa, Asia, and Latin America. They are the poorer segment of the world's population and live in the world's warmest places. Infectious communicable endemic diseases also abound in these poverty areas. Millions of Americans travel to these less developed countries (LDCs), thus exposing themselves to unfamiliar health conditions. The United States no longer requires an immunization certificate for travelers from these LDCs. Tropical diseases also represent a type of pathology infrequently seen by many American medical practitioners. Additionally, the curricula of medical schools allocate only a fractional amount of time to specific disease problems of LDCs. Important gaps exist in both knowledge and application of knowledge in terms of many such diseases.The international travelers to LDCs must not be lulled into believing that travel precautions are unnecessary. Lack of preparedness can be hazardous and even fatal to international travelers. Those who purchase souvenirs such as art works and handicrafts often are not aware that these items may pose health hazards. The health professions, particularly the public health department official, should develop a continuing health education regimen in the area of health care for international travelers. The American traveling public deserves better service in this matter.

Bacteroidosis.
Bacteroides infection frequently complicates surgery, instrumentation, or trauma to the alimentary, upper respiratory, and female genitourinary tracts. Bacteroides sp, alone or with other organisms, also may cause infections in the ear, nose, and throat, and other tissues where defeneses are lowered. Foul-smelling pus, sinus drainage, material from an abscess or infected traumatic wound, or a blood culture made because of a suspected anaerobic complication should be subjected to anaerobic study in the laboratory. Treatment of clinical bacteroidosis consists of specific antibiotics, surgery, oxygen under pressure, and appropriate local dressings. Treatment is often more effective if at least two antibiotics are given concurrently, and antibiotic sensitivity tests are recommended to select the best combination.
