History

The symptoms of dropsy have not changed over the centuries. Its history is the story of evolving interpretations of its clinical features over 2,000 years as the relationships of dyspnea, suffocative catarrh, pulmonary edema, hydrothorax, ascites, syncope, and fever to heart failure were elucidated. The first known mention of dropsy is in the Ebers Papyrus, an Egyptian medical text of about 1550 B.C. It associates dropsy with increased abdominal girth and possibly with a weak pulse. A...

General Characteristics

Because of its acute onset and obvious symptoms, type I diabetes is readily identified and, therefore, permits a more accurate picture of worldwide prevalence. Type II DM is a chronic disease with generalized symptoms therefore, many cases are not diagnosed. However, rates of type II do appear to be increasing in developing nations. Generally, investigators have been cautious in interpreting an actual increase in the incidence of insulin-dependent DM. Prevalence rates continue to rise because...

Mitch Disease Fr Dogs

Rabies occurs in Africa, Asia, the Americas, and most of Europe. It has never occurred in, or has been eliminated from, Britain, Ireland, Sweden, Norway, Japan, Australia, New Zealand, Hawaii, and many islands in the Pacific and Caribbean. Rabies is a disease of wild carnivores, particularly canids such as foxes, wolves, jackals, and coyotes. Skunks and raccoons are also common hosts, as are bats. Virtually any mammal can contract the disease when bitten by an infected animal. Domestic dogs are...

Disease Against Which Vaccination Is Resorted Onlybduring Epidemics

Because it persisted only by passing from one human to another, smallpox could not have existed among the sparse populations of the Paleolithic Age. It may have first appeared sporadically among village dwellers of the Neolithic Age. Smallpox may well have afflicted ancient Egyptians. The face, neck, and shoulders of the mummy of Pharoah Ramses V, who died in 1157 B.C., is disfigured by a rash of elevated pustules, but researchers cannot be sure of the infection that caused them. Dreadful...

Opportunistic and Iatrogenic Infections

Mycetoma is a disease characterized by swelling that affects subcutaneous tissues, with sinuses discharging granules of the pathogen that vary in color. The foot is most frequently involved (Madura foot), but other parts may be infected. Its geographic distribution is mainly tropical. The condition was first recorded in Indian vedic medical treatises (c. 2000-1000 B.C.) as padaavalmika (foot ant-hill) and later described by members of the Indian Medical Service during the mid-nineteenth...

Ringworm Tinea Dermatophytosis

Favus (Latin for honeycomb), a distinctive type of ringworm, was described by Celsus in the first century. He called it porrigo, a term also used by Pliny in the same century and by dermatologists up to the nineteenth century. It is now, however, obsolete, having been replaced by tinea. Celsus also described the inflammatory lesion of some forms of ringworm, which is termed the kerion of Celsus. Not until the mid-1840s was the mycotic nature of favus recognized by three independent workers J....
