All the antibiotics listed in the above table are already in the 19 th WHO Model List of Essential Medicines except TETRACYCLINE and OFLOXACIN as such while AZITHROMYCIN is only listed for single‐ dose treatment of genital Chlamydia trachomatis and of trachoma. I propose to add Neisseria gonorrhoeae and syphilis among the indications of AZITHROMYCIN ( see also the yaws application where AZITHROMYCIN is also indicated in order to achieve eradication). Although, levofloxacin and ofloxacin are effective treatment alternatives, they are more expensive and offer no advantage in the dosage regimen. Other quinolones either are not reliably effective against chlamydial infection or have not been evaluated adequately. I do not recommend to add the quinolones for Chlamydia trachomatis. I also do not recommend to add TETRACYCLINE for Chlamydia trachomatis. I propose to add ERYTHROMYCIN 0.5% EYE OINTMENT in the list of: “21. OPHTHALMOLOGICAL PREPARATIONS 21.1 Anti-infective agents” I do not recommend to add SILVER NITRATE 1% SOLUTION and CHLORAMPHENICOL 1% EYE OINTMENT (4) References 1) 30 August 2016: WHO has today launched new treatment guidelines WHO guidelines for the treatment of Neisseria gonorrhoeae WHO guidelines for the treatment of Treponema pallidum (syphilis) WHO guidelines for the treatment of Chlamydia trachomatis 2) Sexually Transmitted Diseases Treatment Guidelines, 2015 Morbidity and Mortality Weekly Report Vol. 64 / No. 3 June 5, 2015 .

  • Can Leptospirosis Be Treated Without Any Kind of Medication?

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.

The syphilis spirochete’s well-recognized capacity for early dissemination and immune evasion has earned it the designation ‘the stealth pathogen’. Despite the many hurdles to studying syphilis pathogenesis, most notably the inability to culture and to genetically manipulate T. pallidum, in recent years, considerable progress has been made in elucidating the structural, physiologic, and regulatory facets of stealth pathogenicity. In this Review, we integrate this eclectic body of information to garner fresh insights into the highly successful parasitic lifestyles of the syphilis spirochete and related pathogenic treponemes. Pathogenic treponemes cause venereal syphilis, yaws, endemic syphilis, and pinta—multi- stage, infections that, although similar, can be differentiated based on clinical, epidemiologic, and geographic criteria1,2.
