    West Nile Virus Encephalitis in Alanya, Turkey: A Case Report
    (2015) Erdogan, Haluk
    West Nile virus (WNV) serologic evidence has been well demonstrated throughout Turkey. A 43-year-old male patient who presented to emergency service with high fever, rash, muscle weakness, altered mental status and was diagnosed as WNV encephalitis is reported. The patient survived after supportive treatment. This case shows that WNV encephalitis should be considered in the differential diagnosis of patients with aseptic meningitis or encephalitis of unknown etiology especially in summer and early fall in Turkey.

    Domestically Acquired Legionnaires' Disease: Two Case Reports and a Review of the Pertinent Literature
    (2016) Erdogan, Haluk; Arslan, Hande; 27308081
    Background: Legionella species may colonize in home water systems and cause Legionnaires' disease (LD). We herein report two cases of sporadic LD associated with the solar energy-heated hot water systems of the patients' houses. Case Report: A 60-year-old woman with chronic bronchitis and diabetes mellitus presented with a high fever, abdominal pain, and diarrhea. Physical examination revealed rales, and her chest radiograph showed a homogeneous density in the left lung. The Legionella urinary antigen test was positive, and an indirect fluorescent antibody test revealed a serum antibody titer of 1/520 for L. pneumophila serogroup 1. In the second case, a 66-year-old man with diabetes mellitus was treated for pneumonia at another hospital. After the patient's general condition worsened and he required mechanical ventilation, he was referred to our hospital. The Legionella urinary antigen test was positive. Neither of the patients had been hospitalized or travelled within the previous month. Both patients used hot water storage tanks heated by solar energy; both also used an electrical device in the bathroom to heat the water when solar energy alone was insufficient. The hot water samples from the residences of both patients were positive for L. pneumophila serogroup 1. Conclusion: These cases show that domestic hot water systems heated by solar energy must be considered a possible source of community-acquired LD.

    Legionnaires' disease
    (2018) Erdogan, Haluk; 0000-0002-9033-4236; O-2247-2015
    Legionnaires disease is a severe from of pneumonia caused by Legionella species which arc ubiquitious in both natural and man-made environments. It has high morbidity and case fetality rates. The disease is acquired by aspiration of water or inhalation of aerosols containing the bactena from environmental sources. Early diagnosis and appropriate treatment are important factors in determining prognosis. Clinical and laboratory predictors will not reliably identify cases of legionnaires disease, therefore the diagnosis of Legionnaires' disease requires specific diagnostic tests. The diagnosis of Legionnaires' disease is made by culture, Legionella urinary antigenaria, polymeras ion, or serologic analyses. Isolation of Legionella from clinical samples is the gold standart for diagnosing Legioimaire's disease. Legionella urinary antigen tests are easy and useful for early diagnosis of Legionnaires' disease. Flouroquinolones, macrolides and doxycicline are drugs of choice. Legionnaires' disease is considered a preventable illness since it is possible to control and remove the bacteria in reserviors. In Turkey, travel-associated Legionnaires' disease has a specific surveillance programe since 1996. After the year of 2015, it became mandatory to take environmental cultures for Legionella from the hospital water systems. The aim of this review is to raise awereness for legionollosis and to summarize the current literature.
