Huang W L* *Corresponding author Huang Wei Ling, Rua Homero Pacheco Alves, 1929, Franca, Sao Paulo, Infectologist, general practitioner, nutrition doctor, acupuncturist, 14400-010, Brazil, Tel: (+55 16) 3721-2437; E-mail: [email protected] pain management, Medical Acupuncture and Pain Management Clinic, Franca, Sao Paulo, Brazil Submitted: 16 Apr 2018; Accepted: 23 Apr 2018; Published: 10 May 2018 Abstract Introduction: Leptospirosis is an acute infectious disease caused by pathogenic Leptospira. Spread in a variety of ways, though the digestive tract infection is the main route of infection. As the disease pathogen final position in the kidney, the urine has an important role in the proliferation of the disease spreading [1]. Purpose: The purpose of this study was to show if leptospirosis can be treated without any kind of medication. The methodology used was the presentation of one case report of a woman presenting three days of generalized pain all over her body, especially in her muscles, mainly the calves of her legs, fever, headache and trembling. A blood exam was asked, as well as serology and acupuncture to relieve her symptoms. Findings: she recovered very well after five sessions of Acupuncture once a day. A month later, she came back with the results of her serology: it was positive leptospirosis. Conclusion: In this case, leptospirosis was cured without the use any kind of medication, being acupuncture a good therapeutic option, reducing the necessity of the patient’s admittance into a hospital, minimizing the costs of the treatmentand restoring the patient to a normal life very quickly.

KANE, M.D., M.R.C.P.I., D.P.H. Medical Superintendent, Purdysburn Fever Hospital, Belfast IT is unlikely that rat-bite fever will rver become a public health problem in this country, so the justification for publishing the following case lies rather in its rarity, its interesting course and investigation, and in the response to Penicillin. PRESENT CASE. The patient, D. G., born on 1st January, 1929, is the second child in a family of three sons and one daughter of well-to-do parents. There is nothing of import- ance in the family history or the previous history of the boy. Before his present illness he was in good health, was about 5 feet 9j inches in height, and weighed, in his clothes, about 101 stone. The family are city dwellers. On the afternoon of 18th March, 1944, whilst hiking in a party along a country lane about fifteen miles from Belfast city centre, he was bitten over the terminal phalanx of his right index finger by a rat, which held on until pulled off and killed. The rat was described as looking old and sickly. The wound bled slightly at the time, but with ordinary domestic dressings it healed within a few days. Without missing a day from school and feeling normally well in the interval, the boy became sharply ill at lunch-time on 31st March, i.e., thirteen days after the bite.

  • The Consequences of Cook's Hawaiian Contacts on the Local Population
    The Consequences of Cook's Hawaiian Contacts on the Local Population by Peter Pirie Professor of Geography University of Hawaii at MFnoa and Assistant Director, East-West Population Institute The arrival of Captain Cook in Hawaiian waters in 1778 initiated a new and, for the Hawaiians, a calamitous phase in their demographic his- tory: this is beyond dispute. From an insecurely estimated population of c.250,000 Hawaiians in 1778, the population, even of some Hawaiian ancestry, fell to c.84,000 by 1850 and to its nadir of c.37,SOO in 1900. How much of the blame for this tragic episode can be assigned directly to the effect of Cook's contacts with the Hawaiians in 1778-9 and how much was inevitable given the subsequent explosion of interest and contact in the Pacific which Cook's discovery detonated, is a matter about which some controversy may persist. But several writers, including the Hawaiian historian Kamakau, have held Cook culpable (Kamakau, 1961, Ch. VIII, pp. 92-104). As a consequence, Cook's name is held by some in Hawaii in a disrepute not encountered elsewhere in the Pacific region whjch he explored. The journals and other writings which resulted from the two Cook visits refer to the problem of venereal diseases among the crews, to the possibility of their transmission from the newcomers to the Hawaiian population and to the possibility of their previous presence. The aim of this paper will be to test the accuracy and probabilities in- valved in Cook's perception of his expedition's role in this process, but in the light of modern Illndsight.

Syphilis is known as the “great imitator" due to the similarity of clinical signs and symptoms to other infectious diseases. The primary diagnosis of syphilis relies on clinical findings, including the examination of treponemal lesions, and/or serologic tests.

  • Sexually Transmitted Infections Introduction and General Considerations Date Reviewed: July, 2010 Section: 5-10 Page 1 of 13
    Sexually Transmitted Infections Introduction and General Considerations Date Reviewed: July, 2010 Section: 5-10 Page 1 of 13 Background Information The incidence of Sexually Transmitted Infections (STIs) in Saskatchewan has been increasing over the past number of years. This may be due in part to the introduction of testing procedures that are easier to complete and less invasive. In Saskatchewan, the rates for chlamydia have been among the highest in Canada. Refer to http://dsol- smed.phac-aspc.gc.ca/dsol-smed/ndis/c_indp_e.html#c_prov for historical surveillance data collected by Public Health Agency of Canada (PHAC). STIs are transmitted in the context of other social and health challenges; the risk of recurrent exposure and infection are likely unless these underlying issues are dealt with. A holistic assessment of clients assists in identifying these underlying issues and a multidisciplinary team approach is often necessary and should involve other partners such as physicians, addiction services and mental health as required. The regulations of The Health Information Protection Act must be adhered to when involving other partners in the management of individuals or when referring individuals to other agencies. This section highlights some of the general and special considerations that should be kept in mind when conducting STI investigations. It also highlights key points and summarizes the Canadian Guidelines on Sexually Transmitted Infections which can be located at http://www.phac-aspc.gc.ca/std-mts/sti-its/guide-lignesdir-eng.php. Reporting Requirements Index cases must be reported to the Ministry of Health. See Reporting Requirements in the General Information section of this manual for additional information and guidelines.

  • On the Origin of the Human Treponematoses (Pinta, Yaws, Endemic Syphilis and Venereal Syphilis)
    Bull. Org. mond. Sante 1963, Bull. WldHlth Org. 29, 7-41 On the Origin of the Human Treponematoses (Pinta, Yaws, Endemic Syphilis and Venereal Syphilis) C. J. HACKETT, M.D., F.R.C.P.1 A close relationship between the four human treponematoses is suggested by their clinical and epidemiological characteristics and by such limited knowledge ofthe treponemes as there is at present. No treponeme of this group (exceptfor that of the rabbit) is known other than in man, but the human treponemesprobably arose long agofrom an animalinfection. The long period cfinfectiousness ofpinta suggests that it may have been the earliest human treponematosis. It may have been spread throughout the world by about 15 000 B.C., being subsequently isolated in the Americas when the Bering Strait wasflooded. About 10 000 B.C. in the Afro-Asian land mass environmental conditions might have favoured treponeme mutants leading to yaws; from these, about 7000 B.C., endemic syphilis perhaps developed, to give rise to venereal syphilis about 3000 B.C. in south-west Asia as big cities developed there. Towards the end of the fifteenth century A.D. a further mutation may have resulted in a more severe venereal syphilis in Europe which, with European exploration and geo- graphical expansion, was subsequently carried throughout the then treponemally uncom- mitted world. These suggestions find some tentative support in climatic changes which might have influenced the selection of those treponemes which still survive in humid or arid climates. Venereal transmission would presumably remove the treponeme from the direct influence of climate. The author makes a plea for further investigation of many aspects of this subject while this is still possible.
