International Health H.O.:  International Health H.O. Lecture by: Jesse Monestersky,DO,MS,MPH,DTM&H CAPT,MC,USNR(FS,HMO) Contact info: (W) 847-688-6712x5081 Email: Rosalind Franklin University School of Medicine Med II Preventive Medicine Tues, 12 Apr 05, 1000-1100 Enabling Objectives:  Enabling Objectives To understand causes & magnitude of CHEs To know 6 major causes of infectious disease death worldwide To understand difference between emerging & reemerging diseases, surveillance, risk factors To become acquainted with sources for IH rotations To become familiar with travel medicine focus To become aware of sobering realities – the good, the bad, the ugly To become familiar with key TM diseases ROE:  ROE Potpourri of topics Fire hose approach Keep your seatbelts fastened Happy to serve as a future resource Maybe will even excite one of you to pursue career in IH There will be a few questions on your exam from this lecture References:  References Textbooks: Auerbach, PS: Wilderness Medicine: Management of Wilderness & Environmental Emergencies, CV Mosby, 2001 Cook, GC; AI Zumla: PEC Manson-Bahr & DR Bell - Manson’s Tropical Diseases, 21st Ed., WB Saunders, 2002 Jong, EC; R McMullen: The Travel & Tropical Medicine Handbook, WB Saunders, 2002 Magil, AJ: Hunter’s Tropical Medicine & Emerging Diseases, WB Saunders Co., 2000 Steffen; Dupont; Wilder-Smith: Manual of Travel Medicine & Health, 2nd Ed., BC Decker, UK, 2003 Zuckerman, JN: Principles & Practice of Travel Medicine, John Wiley & Sons Publisher, 2001 Societies: American College of Tropical Medicine American Society of Tropical Medicine & Hygiene International Society of Travel Medicine Royal Society of Tropical Medicine & Hygiene (UK) Educational credentials: MPH (Master of Public Health) (Schools of Public Health, PrevMed Departments in Medical Schools) CTH (Certificate of Travel Medicine) DTM&H (Diploma in Tropical Medicine & Hygiene) (LSTM, London SH) Bottom Line, Up Front:  Bottom Line, Up Front International Health: To provide background, educational opportunities & your potential role Try to do a medical rotation overseas, esp., developing country Gain experience in nutrition [esp., peds, malnutrition [marasmus (calorie) vs. kwashikor (protein)], environmental health (food & water sanitation), entomology (medical), infect dx (measles, TB, malaria), diarrhea (ORS) Think about MPH degree or dual MD/MPH (IH, Epi, M&CH) Consider eventual paid or volunteer work abroad; e.g., PC (volunteer, PCMO), USDOS (RMO), DoD (A/D), NGO (MSF) Become more familiar with CHE, Mass disasters, Refugee Medicine International medical perspective mind-broadening You can make a difference (even one person at a time) Even consider specialty you choose if you want overseas work (e.g., IM/ID/TM, Ortho, GenSurg, ENT, Ophthal) Requires change in frame of reference to gain from experience! Carefully preplan your trip to make it meaningful & safe Learn a language or improve your language skills Relevance???:  Relevance??? Are tropical diseases of just historical interest? Emerging & reemerging diseases Global warming is changing disease distribution (e.g., WNF, malaria) With international jet travel, patients can show up anywhere even at a Midwest doc-in-the-box! Future pandemics (e.g., Avian influenza)? Bioterrorism (e.g., smallpox, anthrax) Many diseases remain major killers world-wide (measles, diarrhea, malaria, TB) Developing countries a Petri dish for rest of world Monkeypox:  Monkeypox Ref: CDC MMWR 52(23):537-540; 6/13/03 – Multi-state Outbreak of Monkeypox – IL, IN, WI The 1st case presented to Marshfield Clinic WI for Tx of an infected bite from a pet prairie dog (6/03). Marshfield thought it was an orthopox by EM; specimen sent to CDC lab, which confirmed Dx by PCR. This orthopoxvirus is similar in appearance to smallpox; with low CFR. Human monkeypox was 1st identified in the Democratic Republic of the Congo in a a region where smallpox had been eradicated in 1968. 53 cases; resulting in 14 hospitalizations (26%). S&S: Preceding febrile illness, papular rash, lymphadenopathy, sore throat. Rash progressed through states of vesiculation, pustulation, umbilication, encrustation. Rashes occurred on hands, trunk, extremities; many patients had initial & satellite lesions on palms, soles, extremities. Rashes were generalized in some pts. Epid: All pts had contact with animals (Cynomys sp.) & 1 pt reported contact with a Gambian giant rat (Cricetomys sp.). Investigation revealed that a common distributor was responsible, who housed prairie dogs and Gambian giant rats together. Records revealed that the Gambian giant rats were shipped from Ghana to Texas and then, on to Illinois. Exposures were at a pet swap meet in N. WI. FDA & CDC issued an immediate ban on importation of all rodents from Africa (order Rodentia) Malaria:  Malaria Airport malaria in France Between 1969-98, 63 cases of airport malaria have been reported in W. Europe, 24 of which occurred in France. Most cases due to Plasmodium falciparum. In 1994, 7 cases occurred in & around Roissy Charles de Gaulle airport (CDG), showing 4 types of exposure: employees working on airstrips or opening containers, among residents living near airport, among people living at some distance from airport after a secondary transport of vectors, & by vectors transported in luggage. Prevention is by disinsectization of aircraft, with permethrin aerosol though there is some pyrethroid resistance in Anopheles gambiae in W. Africa.
