Long term effects of tear gases on respiratory system: analysis of 93 cases.

AIM: This study aimed to assess the long-term respiratory effects of tear gases among the subjects with history of frequent exposure. MATERIALS AND METHODS: A questionnaire by NIOSH and pulmonary function tests was performed in 93 males exposed to the tear gases frequently and 55 nonexposed subjects. RESULTS: The mean numbers of total exposure and last 2 years exposure were 8.4 ± 6.4 times, 5.6 ± 5.8 times, respectively. Tear gas exposed subjects were presented with a higher rate for cough and phlegm more than 3 months (24.7% versus 11.3%, P > 0.05). Mean FEV1/FVC and % predicted MMFR in smoker exposed subjects are significantly lower than those in smoker controls (81.7% versus 84.1%, P = 0.046 and 89.9% versus 109.6%, P = 0.0004, resp.). % predicted MMFR in nonsmoker exposed subjects is significantly lower than that in nonsmoker controls (99.4% versus 113.1%, P = 0.05). Odds ratios for chest tightness, exercise dyspnea, dyspnea on level ground, winter morning cough, phlegm, and daily phlegm were increased almost 2 to 2.5 folds among tear gas exposed subjects. CONCLUSION: The rates for respiratory complaints were high in the case of the exposure to the tear gases previously. Tears gas exposed subjects were found to be under the risk for chronic bronchitis

Evaluating unscheduled readmission to emergency department in the early period

Background: The readmission in the early period (RAEP) is defined as the admission of a patient to emergency department (ED) for the second time within 72 hours after discharge from the ED. Aims: The aim of this study was to determine the disease, patient, doctor, and system related causes of RAEP. Study Design: Descriptive study. Methods: This study is a two-stage study that was conducted at Department of Emergency, Gazi University Faculty of Medicine. The causes of RAEP were defined as disease, patient, doctor, and system related causes. Results: A total of 46,800 adult patients admitted to ED during the study period and 779 (1.66%) patients required RAEP. After the exclusion criteria, 429 of these patients were included the study. The most common reasons for RAEP were renal colic in 46 (10.7%) patients. It was detected that 60.4% of the causes of RAEP were related to disease, 20.0% were related to the doctor, 12.1% were related to the patient, and 7.5% were related to the hospital management system. Conclusion: This study revealed that there are patient-, doctor-, and system-related preventable reasons for RAEP and the patients requiring RAEP constitute the high risk group. © 2016 Trakya University Faculty of Medicine

Decorin as a new treatment alternative in Peyronie's disease: preliminary results in the rat model.

The purpose of this study is to investigate the effect of decorin, a naturally occurring proteoglycan with anti-transforming growth factor beta (TGF-) activity, on the rat model of Peyronie's disease (PD). Twenty-five adult male Sprague-Dawley rats were divided in three groups: I) TGF- (0.5g) injected (n: 8); II) TGF- injected and decorin treated (n: 8); and III) controls (n: 9). Decorin (0.5g per day) was given with intracavernous injection on the second, third, fourth and fifth day following TGF- injection. All rats underwent electrical stimulation of the cavernous nerve after 6weeks. Intracavernosal and arterial blood pressures were measured during this procedure. Cross-sections of the rat penises were examined using Mason trichrome and H&E stains. Statistical analyses were carried out using one-way anova. Histopathological examinations confirmed the Peyronie's-like condition in TGF--injected rats, which exhibited a thickening of the tunica albuginea (TA), when compared to controls. Disorganisation of collagen on the TA was also prominent in TGF--injected rats, but not in decorin-treated and control rats. Decorin-treated rats showed significantly higher maximal intracavernosal pressure (MIP) responses to cavernous nerve stimulation, when compared to group 1 (P<0.05). Our results indicate that decorin antagonises the effects of TGF- in the rat model of PD and prevents diminished erectile response to cavernous nerve stimulation

Discrepancies between clinical and pathological findings seen at renal biopsy in rheumatological diseases

Objective. Renal biopsy contributes to the diagnosis, follow-up, and treatment of many rheumatic conditions. This study assessed the diagnostic role and safety of renal biopsies in a tertiary rheumatology clinic. Methods. Renal biopsies performed between June 2020 and December 2022 were screened, and demographic, clinical, histopathological, and safety data were collected from patient records. Results. In this study, 33 males and 38 females were included. Except for 1 patient who received acetylsalicylic acid, antiaggregant, and/or anticoagulant drugs were stopped before the biopsy. Complications included a decrease of hemoglobin in 8 patients (11.3%) and microscopic hematuria in 40 patients (56.3%). Control ultra-sonography was performed in 16 patients (22.5%), and a self-limiting hematoma was found in 4 of them (5.6%) without additional complications. While less than 10 glomeruli were obtained in 9 patients (9.9%), diagnosis success was 94.4%. Histopathological data were consistent with one of the pre-biopsy diagnoses in 54 of 67 cases (80.6%) but showed discrepancies in 19.4% (n=13) of patients. A repeat biopsy was performed in 7 patients for re-staging or insufficient biopsy. Conclusions. Renal biopsy significantly contributes to rheumatology practice, especially in patients with complex clinical and laboratory findings or in whom different treatments can be given according to the presence, severity, and type of renal involvement. Although the possibility of obtaining insufficient tissue and the need for re-staging and repeat biopsy in the follow-up might be expected, complication risk does not seem to be a big concern. Renal biopsy often evidenced discrepancies between pre-biopsy diagnosis and histopathological findings

A snapshot of geriatric infections in Turkey: ratio of geriatric inpatients in hospitals and evaluation of their infectious diseases: A multicenter point prevalence study

Introduction: The human population is aging at an astonishing rate. The aim of this study is to capture a situation snapshot revealing the proportion of individuals aged 65 years and over among inpatients in healthcare institutions in Turkey and the prevalence and type of infections in this patient group in order to draw a road map. Materials and Methods: Hospitalized patients over 65 years at any of the 62 hospitals in 29 cities across Turkey on February 9, 2017 were included in the study. Web-based SurveyMonkey was used for data recording and evaluation system. Results: Of 17,351 patients 5871 (33.8%) were ≥65 years old. The mean age was 75.1 ± 7.2 years; 3075 (52.4%) patients were male. Infection was reason for admission for 1556 (26.5%) patients. Pneumonia was the most common infection. The median length of hospital stay was 5 days (IQR: 2–11 days). The Antibiotic therapy was initiated for 2917 (49.7%) patients at the time of admission, and 23% of the antibiotics prescribed were inappropriate. Healthcare-associated infections developed in 1059 (18%) patients. Urinary catheters were placed in 2388 (40.7%) patients with 7.5% invalid indication. Conclusion: This study used real data to reveal the proportion of elderly patients in hospital admissions. The interventions done, infections developed during hospitalization, length of hospital stay, and excessive drug load emphasize the significant impact on health costs and illustrate the importance of preventive medicine in this group of patients. © 2020 The Author
