Determination of nasal mucociliary clearance time and nasal symptom in patients with Crimean-Congo hemorrhagic fever.

Crimean-Congo hemorrhagic fever (CCHF) is an important health problem in Turkey. Number of studies on symptoms of ear nose throat system and indicating whether or not the organs are affected in patients with CCHF is limited. The aim of the present study was to investigate whether CCHF infections caused any change in nasal physiology in adult patients or not by using saccharin transit time (STT) and nasal symptom scoring. Twenty subjects with laboratory-confirmed diagnosis of CCHF and 28 healthy control subjects were included in the present study. A saccharin test was used to evaluate nasal mucociliary clearance time (NMCT) and the nasal symptom scoring used in allergic rhinitis was modified and used to examine the symptoms of the patients. The average STT of CCHF and control groups were 472.70 ± 151.58 and 276.07 ± 89.65 sec, respectively. The difference between them was statistically significant (P = 0.00, P < 0.05). When those in CCHF group were classified according to timing of the test, STT average of those undergoing the test on the 1st-3rd days (n = 10) and 4th-6th (n = 10) days was 547.00 ± 154.37 and 398.40 ± 111.39 sec, respectively. The difference between them was statistically significant (P = 0.024; P < 0.05). The results of the present study showed that NMCT prolonged in adult patients with CCHF compared to those in the control group despite the fact that it was within normal limits. For these reasons, clinicians should follow-up CCHF patients more closely for respiratory tract diseases and sinonasal and middle ear infections. J. Med.

Assessment of Hematological Factors Involved in Development and Prognosis of Idiopathic Sudden Sensorineural Hearing Loss.

OBJECTIVE: The aim of this study was to investigate the possible effects of routine hematological parameters on the development and prognosis of idiopathic sudden sensorineural hearing loss in patients applying to our clinic. STUDY DESIGN: A retrospective clinical study. SETTING: One academic health center from 2008 to 2014. PATIENTS AND INTERVENTION: One hundred forty patients with sudden hearing loss and 132 healthy controls were included in the present study. RESULTS: Patients having idiopathic sudden sensorineural hearing loss were divided into 2 subgroups based on whether they recovered (complete, partial, and slight recovery) (Group 1; n = 83, 59.3%) or not (Group 2; n = 57, 40.7%) during the follow-up term. Group 1, Group 2, and the controls differed statistically significantly in terms of neutrophil-to-lymphocyte ratio (P = 0.001), platelet-to-lymphocyte ratio (P = 0.001), lymphocytes % (P = 0.001), mean corpuscular hemoglobin (P = 0.019), mean corpuscular hemoglobin concentration (P = 0.015), platelet (P  = 0.001), mean platelet volume (P = 0.001), platelet distribution width (P = 0.009), and glucose (P = 0.001). The study groups and the controls did not have any significant difference in terms of other laboratory parameters affecting the prognosis of Idiopathic sudden sensorineural hearing loss. CONCLUSIONS: The results the authors obtained showed that laboratory parameters such as lymphocyte, lymphocyte%, platelet, mean platelet volume, platelet distribution width, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration may be indicative for prognosis and treatment success in groups of patients suffering idiopathic sudden sensorineural hearing loss in whose etiology many factors play a role.
