These combined effects result in fibers that are hydrophilic, of reduced tensile and torsional strength, are prone to tangling, and show an increased rate of weathering (Table 2).

There are, however, a number of clinical markers that will point the clinician to poor cosmetic practices. Trichorrexhis Nodosa Investigation: When numerous fibers are affected, small white spots are easily seen on the hair with the naked eye and can be confirmed with a hand lens. Transmitted or plane polarized light microscopy shows characteristic focal burst along the fiber or brush breaks where the node has parted. Additional observations should be made of the apparently normal parts of the fiber to rule out any predisposing conditions, such as pili annulati or pili torti, that may previously have gone unnoticed. While it is important to exclude any underlying pathology or metabolic changes, it is unlikely that a patient who previously had normal hair will have developed significantly weaker hair. It must be remembered that where trichorrhexis nodes appear toward the tips on longer fibers, that part of the hair was actually formed many months before the patient pre- sented with trichorrexhis nodosa. However, the combination of insults and insufficient care may result in catastrophic fiber damage. In order to understand 26 Gummer the severity of a patient’s cosmetic regimen it may be useful to measure the distance from the scalp to the first onset of trichorrhexis nodosa as an indication of how long the best part of the fiber can withstand the current level of trauma. It is probable that a chemical (permanent wave) or thermal (tongs) insult is indicated in the process. The current fashion trend for per- fectly straight hair has spawned a number of treatments and straightening irons that claim to be good for the hair. The author has observed an increase in trichorrhexis nodosa among young females who are seemingly “wedded” to their straightening irons. Bubble Hair Investigation: Routine light microscopy, or a hand lens, reveals swelling and honeycomb-like structures at the broken, distal end of the fiber (5). Very small (~5 micron) dome-like protrusions on cuticle scales are com- mon on normal hair, though difficult to see by light microscopy, and should not be confused with bubble hair. The patient presents with a single episode of claimed hair loss that may affect either the whole of the scalp or one of more poorly defined areas. When associated with a specific chemical treatment, hair breakage often begins several days after the causative procedure. Investigation: True hair loss from the follicle rarely, if ever, occurs due to cosmetic prac- tices. Routine light microscopy of the shed fibers normally shows a fracture or trichorrhexis nodosa brush break at the proximal end. The distal end can present either as damaged, or often as a clean scissor cut, particularly when a haircut has preceded a chemical treatment. Matting or Tangling Even hair in perfect condition is prone to tangling, especially when wet. Severe tangling or matting, which may be impossible to unravel, can occur in hair approaching shoulder length or longer and is an indication of both poor hair condition and poor handling of the hair.

These diseases are a leading cause of morbidity and mortality around the world and remain an enigma to many. The new threat of bioterrorism has become a significant security concern of all nations. The text was initially written in the early 20th century, as a pamphlet for New England health officials, by Dr. In 1917, it was published in Public Health Reports (32:41:1706–1733), by the United States Public Health Service. Its 30 pages contained disease control measures for the 38 communicable diseases that were then reportable in the United States. This manual is now the classic by which all other infectious disease manuals are measured. Even the last word in the title was changed from “Man” to “Manual” to remove the perception of gender bias. Translations into several languages—currently Bahasa Indonesia, Italian, Korean, Portu- guese, Serbian, and Spanish—have made this text a global treasure. It covers over 140 diseases and groups of diseases of importance to communicable disease hunters and researchers. Heymann and his team at the World Health Organization have assembled an impressive group of experts from around the world to serve as reviewers, authors, and editors. They have completed the transforma- tion of this text into a resource responsive to the needs of the global health xviii community. I also want to thank the many men and women who work silently behind the scenes and on occasion have given their lives to contain the threat of infectious disease. The microbial agents that cause them are dynamic, resilient, and well adapted to exploit opportunities for change and spread.

Control of patient, contacts and the immediate environment: 1) Report to local health authority: Official report not ordinarily justifiable, Class 5 (see Reporting). Given in a single oral dose of 150 micrograms/kg, with annual retreatment, this reduces microfilarial load and mor- bidity; it kills microfilariae and also blocks release of micro- filariae from the uterus of the adult worm, effectively reduc- ing the number of microfilariae in the skin and eyes over a period of 6–12 months. In endemic communities, ivermectin treatment for whole eligible population at least once yearly is recommended. Research is under way to develop safe and effective drugs that would sterilize or kill the adult worm; some of these are undergoing clinical trials. Suramin kills the adult worms and leads to gradual disappearance of microfilariae, but possible neph- rotoxicity and other undesirable reactions require close medical supervision of its use. Epidemic measures: In areas of high prevalence, concerted efforts to reduce incidence, taking measures listed under 9A. Control has been based mainly on antiblackfly measures, with insecticides applied systemati- cally to breeding sites in the rivers of the area. Ivermectin is now being distributed to communities on an ever-increasing scale as a replacement for larviciding. Identification—A proliferative cutaneous viral disease transmissi- ble to humans through contact with infected sheep and goats, and, occasionally, wild ungulates (deer, reindeer). The lesion in humans, usually solitary and located on hands, arms or face, is a red to violet vesiculonodule, maculopapule or pustule, progressing to a weeping nodule with central umbilication. Diagnosis is through a history of contact with sheep, goats or wild ungulates, in particular their young; in the presence of negative results of conventional bacteriology, through electron microscopy demonstration of ovoid parapoxvirions in the lesion or by growth of the virus in ovine, bovine or primate cell cultures; or through positive serological tests. The agent is closely related to other parapoxviruses that can be transmitted to humans as occupational diseases such as milkers’ nodule virus of dairy cattle and bovine papular stomatitis virus of beef cattle. Contagious ecthyma parap- oxvirus of domesticated camels may infect people on rare occasions. Occurrence—Probably worldwide among farm workers; a com- mon infection among shepherds, veterinarians and abattoir workers in areas producing sheep and goats and an important occupational disease in New Zealand. Mode of transmission—Direct contact with the mucous mem- branes of infected animals, with lesions on udders of nursing dams, or through intermediate passive transfer from apparently normal animals contaminated by contact, knives, shears, stall manger and sides, trucks and clothing. Human lesions show a decrease in the number of virus particles as the disease progresses. Susceptibility—Susceptibility is probably universal; recovery pro- duces variable levels of immunity. Preventive measures: Good personal hygiene and washing the exposed area with soap and water. The efficacy and safety of Parapoxvirus vaccines in animals has not been fully determined. Control of patient, contacts and the immediate environment: 1) Report to local health authority: Not required, but desirable when a human case occurs in areas not previously known to have the infection, Class 5 (see Reporting).
