The aims of the current study are to describe a case of POGS with uveitis due to flea-borne typhus (FBT) and to present a diagnostic and therapeutic approach to POGS. The patient, a 38-year old man, presented with persistent unilateral eye pain, fever, rash, preauricular and submandibular lymphadenopathy, and laboratory findings of FBT: hyponatremia, elevated transaminase and lactate dehydrogenase levels, thrombocytopenia, and hypoalbuminemia. His condition rapidly improved after starting doxycycline. Soon after hospitalization, he was diagnosed with uveitis, which responded to topical prednisolone. To derive a diagnostic and empiric therapeutic approach to POGS, we reviewed the cases of POGS from its various causes since 1976 to discern epidemiologic clues and determine successful diagnostic techniques and therapies; we found multiple cases due to cat scratch disease (CSD; due to Bartonella henselae) (twelve), tularemia (ten), sporotrichosis (three), Rickettsia conorii (three), R. -

Chlamydia-English
URGENT and PRIVATE IMPORTANT INFORMATION ABOUT YOUR HEALTH DIRECTIONS FOR SEX PARTNERS OF PERSONS WITH CHLAMYDIA PLEASE READ THIS VERY CAREFULLY Your sex partner has recently been treated for chlamydia. Chlamydia is a sexually transmitted disease (STD) that you can get from having any kind of sex (oral, vaginal, or anal) with a person who already has it. You may have been exposed. The good news is that it’s easily treated. You are being given a medicine called azithromycin (sometimes known as “Zithromax”) to treat your chlamydia. Your partner may have given you the actual medicine, or a prescription that you can take to a pharmacy. These are instructions for how to take azithromycin. The best way to take care of this infection is to see your own doctor or clinic provider right away. If you can’t get to a doctor in the next several days, you should take the azithromycin. Even if you decide to take the medicine, it is very important to see a doctor as soon as you can, to get tested for other STDs. People can have more than one STD at the same time. Azithromycin will not cure other sexually transmitted infections. Having STDs can increase your risk of getting HIV, so make sure to also get an HIV test. SYMPTOMS Some people with chlamydia have symptoms, but most do not. Symptoms may include pain in your testicles, pelvis, or lower part of your belly. You may also have pain when you urinate or when having sex. Many people with chlamydia do not know they are infected because they feel fine. -
Genetic Diversity of Bartonella Species in Small Mammals in the Qaidam
www.nature.com/scientificreports OPEN Genetic diversity of Bartonella species in small mammals in the Qaidam Basin, western China Huaxiang Rao1, Shoujiang Li3, Liang Lu4, Rong Wang3, Xiuping Song4, Kai Sun5, Yan Shi3, Dongmei Li4* & Juan Yu2* Investigation of the prevalence and diversity of Bartonella infections in small mammals in the Qaidam Basin, western China, could provide a scientifc basis for the control and prevention of Bartonella infections in humans. Accordingly, in this study, small mammals were captured using snap traps in Wulan County and Ge’ermu City, Qaidam Basin, China. Spleen and brain tissues were collected and cultured to isolate Bartonella strains. The suspected positive colonies were detected with polymerase chain reaction amplifcation and sequencing of gltA, ftsZ, RNA polymerase beta subunit (rpoB) and ribC genes. Among 101 small mammals, 39 were positive for Bartonella, with the infection rate of 38.61%. The infection rate in diferent tissues (spleens and brains) (χ2 = 0.112, P = 0.738) and gender (χ2 = 1.927, P = 0.165) of small mammals did not have statistical diference, but that in diferent habitats had statistical diference (χ2 = 10.361, P = 0.016). Through genetic evolution analysis, 40 Bartonella strains were identifed (two diferent Bartonella species were detected in one small mammal), including B. grahamii (30), B. jaculi (3), B. krasnovii (3) and Candidatus B. gerbillinarum (4), which showed rodent-specifc characteristics. B. grahamii was the dominant epidemic strain (accounted for 75.0%). Furthermore, phylogenetic analysis showed that B. grahamii in the Qaidam Basin, might be close to the strains isolated from Japan and China. -

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. -
