War and infection in the pre-antibiotic era: the Third Ottoman Army in 1915.

BACKGROUND: The aim of this study, which evaluated historical data, was to delineate the probable impacts of infectious diseases on human populations under extraordinary circumstances. The second goal was to disclose the mortality rates for infectious diseases in the absence of antibiotics. METHODS: The Third Ottoman Army records at the Turkish General Staff Military History and Strategic Study Directorate were studied retrospectively for the period between March 1915 and February 1916. RESULTS: For the Third Ottoman Army, the number of infection-related deaths over the single-year period was 23,601. Malaria, relapsing fever and dysentery were the most common infections. In that pre-antibiotic era, the highest mortality rates were seen for cholera (80%), pulmonary tuberculosis (58%) and typhoid fever (51%). However, typhus had the maximum share in soldier deaths (6053 soldiers). The rate of vector-borne infections peaked in the summer of 1915, while the frequency of respiratory tract infections was highest in the colder months. In contrast, gastrointestinal tract infections appeared to maintain a steady state throughout the year. CONCLUSIONS: If the wartime data for 1915 are accepted to provide a model for extraordinary circumstances in the 21st century, vector-borne, respiratory tract and gastrointestinal infections can be accepted as the challenging issues with significant mortality.

The spectrum of diseases causing fever of unknown origin in Turkey: a multicenter study.

OBJECTIVE: The purpose of this trial was to determine the spectrum of diseases with fever of unknown origin (FUO) in Turkey. METHODS: A prospective multicenter study of 154 patients with FUO in twelve Turkish tertiary-care hospitals was conducted. RESULTS: The mean age of the patients was 42+/-17 years (range 17-75). Fifty-three (34.4%) had infectious diseases (ID), 47 (30.5%) had non-infectious inflammatory diseases (NIID), 22 (14.3%) had malignant diseases (MD), and eight (5.2%) had miscellaneous diseases (Mi). In 24 (15.6%) of the cases, the reason for high fever could not be determined despite intensive efforts. The most common ID etiologies were tuberculosis (13.6%) and cytomegalovirus (CMV) infection (3.2%). Adult Still's disease was the most common NIID (13.6%) and hematological malignancy was the most common MD (7.8%). In patients with NIID, the mean duration of reaching a definite diagnosis (37+/-23 days) was significantly longer compared to the patients with ID (25+/-12 days) (p=0.007). In patients with MD, the mean duration of fever (51+/-35 days) was longer compared to patients with ID (37+/-38 days) (p=0.052). CONCLUSIONS: Although infection remains the most common cause of FUO, with the highest percentage for tuberculosis, non-infectious etiologies seem to have increased when compared with previous studies.

A case of mucosal leishmaniasis: Mimicking intranasal tumor with perforation of septum.

A 79-year-old male suffering from nasal congestion was referred to our hospital. Endoscopic examination revealed a hyperemic mass obstructing the left nasal passage. The lesion's surface was smooth. The findings of imaging studies were consistent with a benign tumor despite the erosion and perforation of the septum. The lesion originated from the middle concha and was attached to it with a thin stalk. It was removed easily by endoscopic resection. Histopathology revealed significant infiltration of mononuclear inflammatory cells, mostly lymphocytes and histiocytes, into the edematous subepithelial connective tissue. High-power magnification showed numerous Leishmania amastigotes in the cytoplasm of the histiocytes. A polymerase chain reaction experiment for Leishmania also confirmed the morphological diagnosis. No relapse was observed in the 12 months after surgery and the patient was doing well.

Oropharyngeal tularemia cases admitted to a military hospital in Ankara, Turkey.

INTRODUCTION: This study aimed to review the possible sources of infection of 16 oropharyngeal tularemia hospital cases, and to document their epidemiological and demographical characteristics, laboratory findings, treatment methods, and treatment results. METHODOLOGY: Sixteen cases from a Turkish military hospital between January 2011 and December 2012 were retrospectively evaluated. The age, sex, occupation, place of residence, symptoms, duration of symptoms, laboratory results, treatment and duration, and treatment results were recorded. Tularemia was diagnosed through tularemia-specific tests once the other conditions that may have caused lymphadenopathy were excluded. RESULTS: Twelve of the patients included in this study were males. The average age of the patients was 32.1 ± 17.2 years. Sore throat, fatigue, and fever were the most frequent symptoms. The mean duration of symptoms was 21.6 ± 6.9 days. All the patients had been treated for tonsillopharyngitis in primary healthcare institutions previously. However, despite the treatment, cervical lymphadenopathy had developed in these cases. Patients were given streptomycin, doxycycline, and ciprofloxacin monotherapy or in combination. Ten of the cases fully recovered, while five required surgical lymph node drainage. Spontaneous drainage occurred in the single remaining case. CONCLUSIONS: Turkey is considered to be an endemic country with regards to tularemia. Prompt diagnosis and proper treatment of the disease is imperative in providing cure. Since it can be potentially confused with tuberculous lymphadenitis, differential diagnosis is vital. Patients presenting with a condition of tonsillopharyngitis in endemic areas must be carefully monitored.

Management of neurobrucellosis: an assessment of 11 cases.

OBJECTIVE: The central nervous system involvement of Brucellosis causes a hard to treat infection with multiple sequelae. The aim of this paper is to discuss the course of neurobrucellosis in response to therapy. PATIENTS AND METHODS: Patients with neurobrucellosis were evaluated. The diagnosis was established by the isolation of bacteria, abnormal CSF findings and positive serology. Ceftriaxone, rifampicin, doxycycline and trimethoprim sulfamethoxazole were the antibiotic choices for these cases. RESULTS: We present 11 cases with neurobrucellosis. None of our patients died, albeit one case has a critical situation due to subarachnoid hemorrhage and its' concordant sequelae. Only one of four patients with walking difficulty and two with hearing loss were normalized with therapy. Imaging techniques did not provide any specific contribution regarding the Brucella infection. CONCLUSIONS: Parenteral ceftriaxone should be used as an initial alternative in the management of neurobrucellosis. Although the therapy should be individualized, the duration of therapy should be a minimum of six months with suitable antibiotics.

Prophylactic Saccharomyces boulardii in the prevention of antibiotic-associated diarrhea: a prospective study.

BACKGROUND: Interest to probiotics for the prevention and treatment of antibiotic-associated diarrhea is increasing gradually. The most promising seems to be Saccharomyces boulardii . Using a double-blind controlled study, we investigated the preventive effect of S. boulardii on the development of antibiotic-associated diarrhea in patients under antibiotherapy but not requiring intensive care therapy. MATERIAL/METHODS: All the patients were hospitalized at the Gulhane Military Medical Academy, Department of Infectious Diseases and Clinical Microbiology. S. boulardii was given twice daily during the course of antibiotic therapy and application was initiated in all patients as late as after 48 hours of antibiotic therapy. A total of 151 patients completed the study. RESULTS: The antibiotic-associated diarrhea development ratio in placebo group was 9% (7/78) and in the study group 1.4% (1/73) (p < 0.05). Stool samples from the patients with antibiotic-associated diarrhea were stored at -70 degrees C and Clostiridium difficile toxin A assay was performed using Enzyme Immune Assay as late as in seven days. C. difficile toxin A assay yielded positive results in two (2/7) stool samples from the patients with antibiotic-associated diarrhea in the placebo group and a negative result in the only patient who developed antibiotic-associated diarrhea in the study group. CONCLUSIONS: The results implied that prophylactic use of Saccharomyces boulardii resulted in reduced, with no serious side effects, antibiotic-associated diarrhea in hospitalized patients.
