RESUMEN
OBJECTIVE: Lung computed tomography (CT) is a valid method for the detection and assessment of the progression of interstitial lung disease (ILD) in rheumatoid arthritis (RA) patients. The objective of this study is to conduct a comparative analysis of the characteristics of individuals with RA-ILD, with and without radiographic progression, determined using lung CT scans. METHOD: In this retrospective observational study, three radiologists re-evaluated CT scans of RA-ILD patients who had at least one follow-up CT. The lungs were divided into upper, middle, and lower zones, with equal slices. Progression was defined as the involvement of more zones in the vertical extent by the same elementary findings or the emergence of more severe findings in the same zones compared to the previous examination. Logistic regression analysis was used to assess the possible factors identified in univariate analysis. RESULTS: This study included 104 patients with 215 lung CT scans for analysis. Radiographic progression was seen in 43 patients (41.3%). Male sex, findings compatible with ILD on the last X-ray, age at diagnosis of ILD > 50 years, and presence of ground-glass opacity on CT were more common in the group with progression. In multivariate analysis (adjusted for ILD disease duration), findings consistent with ILD on chest X-ray and male sex were independent risk factors for progression, while taking methotrexate (ever) was an independent protective factor for progression. CONCLUSION: Our findings indicate a negative association between methotrexate use and ILD progression. These results should be confirmed in further studies.
RESUMEN
BACKGROUND: The most important factors affecting the development of postoperative hypocalcaemia (PH) include intraoperative trauma to the parathyroid glands, incidental parathyroidectomy (IP), and the surgeon's experience. In this study, we aimed to determine the incidence of IP, evaluate its effect on postoperative calcium levels and investigate the effect of surgeon experience and volume on IP incidence and postoperative calcium levels. METHODS: This retrospective study included 645 patients who underwent thyroid surgery at the Department of General Surgery, Kütahya Health Sciences University between September 2016 and March 2020. All patients underwent surgery at a single clinic by general surgeons experienced in thyroid surgery and their residents (3-5 years). RESULTS: Normal parathyroid glands were reported in 58 (8.9%) of 645 patients. In 5 (8.6%) of 58 patients the parathyroid gland was detected in the intrathyroidal region. PH developed in ten patients (17.2%) with incidental removal of the parathyroid glands. A statistically significant difference was found between the number of incidentally removed parathyroid glands and the development of hypocalcaemia (p<0.05). Normal parathyroid glands were reported in the pathology of 37 (7.9%) patients operated on by general surgeons and 22 (12.6%) patients operated on by their residents. PH developed in 39 (8.2%) patients operated on by general surgeons and in 8 (4.5%) patients operated on by their residents. CONCLUSIONS: We found that the complication rate during the resident training process was the same as that of experienced general surgeons. A thyroidectomy can be safely performed by senior residents during residential training.

OBJECTIVE: The aim of this study was to describe the Computed Tomography (CT) features of pulmonary embolism in patients hospitalized for acute COVID-19 pneumonia and to evaluate the prognostic significance of these features. PATIENTS AND METHODS: This retrospective study included 110 consecutive patients who were hospitalized for acute COVID-19 pneumonia and underwent pulmonary computed tomography angiography (BTPA) on the basis of clinical suspicion. The diagnosis of COVID-19 infection was determined by CT findings typical of COVID-19 pneumonia and/or a positive result of a reverse transcriptase-polymerase chain reaction test. RESULTS: Of the 110 patients, 30 (27.3%) had acute pulmonary embolism and 71 (64.5%) had CT features of chronic pulmonary embolism. Of the 14 (12.7%) patients who died despite receiving therapeutic doses of heparin, 13 (92.9%) had CT features of chronic pulmonary embolism and 1 (7.1%) of acute pulmonary embolism. CT features of chronic pulmonary embolism were more common in deceased patients than in surviving patients (92.9% vs. 60.4%, p=0.01, respectively). Low oxygen saturation and high urine microalbumin creatinine ratio at admission in COVID-19 patients are important determinants of mortality after adjusting for sex and age in logistic procedures. CONCLUSIONS: CT features of chronic pulmonary embolism are common in COVID-19 patients undergoing Computed Tomography Pulmonary Angiography (CTPA) in the hospital. The coexistence of albuminuria, low oxygen saturation and CT features of chronic pulmonary embolism at admission in COVID-19 patients may herald fatal outcomes.

OBJECTIVE: The number of studies in the field of andrology is increasing day by day, but a bibliometric study covering the entire literature on andrology has not yet been conducted. This bibliometric study aims to shed light on the question of where we came from and where we are going in andrology from past to present. It also aimed to summarize the intellectual structure of andrology to reveal global productivity and identify and map the latest trends of scientific articles published in the field of andrology. MATERIALS AND METHODS: 16,659 articles published between 1980 and 2022 were extracted from the Web of Science and analyzed using various statistical methods. Bibliometric network visualization maps revealed trending topics, global productivity, the most influential studies, and international collaborations. Spearman's correlation analysis was used for determining correlations. RESULTS: The top three productive countries were United States of America (3,452; 20.7%), China (2,300; 13.8%), and Germany (1,069; 6.4%). The top two most productive authors were Agarwal A. (n=130) and Nieschlag E. (n=130). The most productive institution was the Egyptian Knowledge Bank (n=422). From past to present, the most studied subjects were testis, male infertility, spermatozoa, testosterone, infertility, erectile dysfunction, spermatogenesis, sperm, prostate cancer (PCA)/neoplasms, oxidative stress, fertility/fertilization, semen, rat(s), apoptosis, azoospermia, sperm motility, human and varicocele. CONCLUSIONS: The trend topics that have been researched more in recent years include erectile dysfunction, oxidative stress, prostate cancer, sperm quality, sperm parameters, infertility, premature ejaculation, diabetes mellitus, obesity, prognosis, sperm DNA fragmentation/damage, antioxidant, asthenozoospermia, varicocelectomy, COVID-19, inflammation, prostatectomy, metabolic syndrome, hypogonadism, benign prostatic hyperplasia, lower urinary tract symptoms, meta-analysis, sexual dysfunction, peyronie's disease, and proliferation. We identified the research leadership of China, Japan, Turkey and India, in addition to Western countries, such as the USA and European countries.

OBJECTIVE: Pulmonary embolism as a potential complication that may occur late in the course of COVID-19 cases. The aim of our study is to evaluate the frequency of pulmonary embolism in patients with new or ongoing dyspnea after a COVID-19 infection. PATIENTS AND METHODS: This is a single-center, prospective observational study to evaluate the clinical and radiological outcomes of consecutive patients presenting outpatient clinic diseases to the chest and a new or ongoing dyspnea after a COVID-19 infection. Demographic, clinical and laboratory data were collected. Dyspnea was evaluated according to the New York Heart Association (NYHA) classification. RESULTS: Pulmonary embolism was detected in 23.8% (25/105) of patients with new or ongoing dyspnea after a COVID-19 infection. Proportion of pulmonary embolism in patients with NYHA classes I, II, III and IV were respectively 8.7%, 20.0%, 30.0% and 35.3% (p for trend=0.02). Compared to NYHA class I and II patients with dyspnea, those in NYHA classes III and IV showed a higher rate of pulmonary embolism [31.6% vs. 14.6%, OR: 2.7 (1.0 to 7.1), p=0.04, respectively]. In Logistic Procedures, NYHA classes of dyspnea (OR: 4.3, 95% CI: 1.2 to 16.6, p=0.03) (NYHA class III and IV vs. NYHA class I and II) determine the likelihood of pulmonary embolism after COVID-19 infection. CONCLUSIONS: Pulmonary embolism is common in patients with new or ongoing shortness of breath after a COVID-19 infection. Pulmonary embolism is more likely to develop in patients with higher NYHA classes.

The duration and intensity of exercise are significant factors in oxidative, morphological, and functional changes of the gastrointestinal tract. This study aimed to investigate the effects of both exhaustive swimming and probiotic VSL#3 on rats that had been previously trained with moderate swimming. The rats were divided into four groups labeled: control (C), probiotic (P), exercise (E), and probiotic-exercise (PE). Groups P and PE were fed with probiotic mixture VSL#3. Groups E and PE had a 5-week moderate swimming program (1 h/day for 5 days/week), followed by a 1-week exhaustive swimming program (trained like in moderate program but 3 times with 150 min resting sessions, for 5 days/week). At the end of the program, the rats were euthanized. Malondialdehyde, superoxide dismutase, catalase, and reduced glutathione levels were measured in tissue samples from the gastrocnemius muscle, heart, liver, kidney, and colon. In vitro contractile activity and histomorphology of the colon were also determined. Exercise and/or probiotic decreased the oxidative stress and also increased the level of one or more of the antioxidant enzymes in some of the organs. Probiotics had more pronounced effects on colon morphology than exercise but unexpectedly this effect was non-trophic. In the colon, the thickness of the tunica muscularis and the number of goblet cells were not affected; however, probiotic administration decreased the crypt depth and tunica mucosa thickness. Exercise increased the Emax value of acetylcholine (ACh), while decreased its sensitivity. These findings suggest that exhaustive swimming does not cause oxidative stress and that probiotic consumption improves oxidative balance in trained rats. The probiotic intake does not alter the effect of exercise on the contractile activity of the colon. Colon mucosal changes induced by probiotics are independent of exercise.

BACKGROUND: The aim of this study was to compare the retreatment time and the removal efficiency of different root canal sealers using WaveOne Gold reciproc file system by measuring required time. MATERIALS AND METHODS: Forty-five mandibular premolars were prepared and randomly divided into three groups (n = 15). In Groups 1-3, the canals were filled with gutta-percha and mineral trioxide aggregate (MTA) Fillapex, EndoREZ, and AH26, respectively. After 7 days, root canal filling materials (RCFM) were removed with WaveOne Gold reciproc files by measuring time. Teeth were grooved and sectioned longitudinally, then remaining RCFM was evaluated using digital camera. The images were transferred to image analysis software to measure the areas of remaining RCFM. Data were analyzed using one-way analysis of variance and Tukey's test (α = 0.05). RESULTS: There was a statistically significant difference between groups according to time required for removing RCFM (P < 0.05). The time required for removing RCFM was significantly shorter in Group 1 and longer in Group 3 than the other groups (P < 0.05). In Group 1, the remaining RCFM was more than other groups at middle third (P < 0.05), but there was no statistically significant difference between groups at coronal and apical thirds (P > 0.05). CONCLUSIONS: None of the sealers evaluated in this study could completely be removed from the root canals. MTA-based sealer was removed faster than resin-based sealers.

OBJECTIVE: To examine the effects of Castellani's paint on symptomatic relief and skin flora in patients with an itchy external ear canal. METHODS: Subjective pruritus scores, and erythema and desquamation scores, were noted in 61 patients with an itchy external ear canal. External ear canal skin swabs were taken for bacterial and fungal cultures. Patients were then randomly divided into three groups: either Castellani's paint (group one) or steroid ear drops (group two) were instilled, or non-impacted cerumen was removed (group three). Patients were re-assessed at one month after the initial visit. RESULTS: After treatment, subjective pruritus scores were significantly lower in all groups, erythema scores were significantly decreased in group one, and desquamation scores were significantly reduced in groups one and two, when compared with pre-treatment scores. Reproduction density of bacteria including normal flora was decreased in group one. However, the types of bacteria that constitute the normal flora of the external ear canal were unchanged. CONCLUSION: Castellani's paint can be administered safely, effectively and easily, without affecting the type of external ear canal skin bacteria, in patients with an itchy external ear canal.

INTRODUCTION: Cholecystectomy for symptomatic cholecystitis is one of the common surgical procedures in the geriatric patients. Increased gallbladder wall thickness is expected due to acute cholecystitis and in some other clinical conditions. Routine histopathological evaluation of cholecystectomy materials are required to confirm the diagnosis and document other pathologies. The aim of this study was to evaluate age-related histopathological gallbladder morphometric measurements. METHODS: A retrospective chart review of 371 cholecystectomy materials was performed. Two groups were designed according to age (<65 and ≥65 years old, respectively). Age and gender analyses for histopathological gallbladder length, diameter and wall thickness were performed. In addition, pathologically confirmed acute inflammation rates were evaluated in this case-control study. RESULTS: Gallbladder morphometric measurements and pathologically confirmed acute inflammation rates were similar in males and females. Histopathological gallbladder diameter was higher with acute inflammatory changes, but no differences were observed in gallbladder length and wall thickness. Gallbladder wall thickness and pathologically confirmed acute inflammation rates were not comparable between the control and geriatric patients (2.8 ± 1.3 vs 2.6 ± 1.2 mm, and 30/281 (10.7 %) vs 10/74 (13.5 %), respectively, p > 0.05). However, higher gallbladder length and diameter were observed in geriatric group. CONCLUSION: Age is an independent factor on histopathological gallbladder length and diameter, but not for gallbladder wall thickness. In addition, pathologically confirmed acute inflammation rate is not higher in geriatric patients. Clinical significance of these findings merits further investigation.

OBJECTIVE: Studies in animals have provided key evidence that antagonizing TNF-α is a viable therapeutic strategy for diffuse severe brain injury. This study is planned to prevent post-traumatic secondary tissue damages in rat diffuse severe brain injury model, which is induced by alone or combined administration of Etanercept and lithium chloride (LiCl). MATERIALS AND METHODS: Male Sprague-Dawley rats were used in the current study. Rats were divided into 5 groups. Trauma was not induced and treatment was not applied to rats of Sham group. For rats of Trauma+Saline group, saline 0.9% was administered via intraperitoneal (i.p.) route at dose of 1 mg/100 g body weight 1 hour after trauma. For rats of Trauma+Etanercept group, Etanercept was administered via i.p. route at dose of 5 mg/kg body weight 1 hour after trauma. For rats of Trauma+LiCl group, LiCl was administered via i.p. route at dose of 50 mg/kg body weight 1 hour after trauma. For rats of Etanercept+LiCl group, Etanercept and LiCl were administered via i.p. route at dose of 5 mg/kg body weight and 50 mg/kg body weight, respectively, 1 hour after trauma. Serum glial fibrillary acidic protein (GFAP) and Tau levels were analyzed with ELISA. For analyses H&E, TUNEL, GFAP and TNF-α staining methods were used. RESULTS: We demonstrate that Etanercept treatment reduced the TBI-induced brain tissues alteration, reduced the expression of TNF-α and improve edema and axonal swelling. We observed a significant decrease in TNF-α and GFAP positivity after LiCl was administered. CONCLUSIONS: The findings obtained in this study suggest that the combination therapy with Etanercept and LiCl decreased neuronal degeneration and alleviated secondary tissue damage in post-traumatic period.

AIM: Aim of this study is to evaluate the diagnostic efficacy of Glial Fibrillar Acidic Protein (GFAP) particularly in minor head traumas. MATERIALS AND METHODS: 72 female and male, 3 month-old, Sprague Dawley rats were used in the study. The rats were divided into 9 groups. Following anesthesia, all rats were placed in prone position. A 10 mm long and 3 mm thick stainless steel metal disc was fixed onto the skull using dental paste in order to sustain a closed head trauma and evenly distribute the weight throughout the skull. After placing it under the metallic pipe arrangement over a height of 80 centimeters and fixing to make it constant, 50 g metallic discs were released by free fall, and the head trauma was sustained thanks to the gravity-generated force. Blood samples were collected from the rats under anesthesia for biochemical GFAP analysis 10 minutes after the trauma and in 1, 2, 3, 4, 5, 6 and 24 consecutive hours later. RESULTS: GFAP has a peak, and its peak level at hours 1 and 2 in rats subjected to a minor head trauma, with a slight decrease afterwards. CONCLUSIONS: GFAP is an important marker in determining the severity of traumatic brain injury.

OBJECTIVE: Insulin resistance (IR) and disorders of glucose metabolism (DGM) are risk factors for cardiovascular diseases. There are different reasons for development of DGM in patients with obstructive sleep apnoea syndrome (OSAS) and this association is controversial. We investigated the frequency of DGM and IR in patients with OSAS and determining factors for these disorders. METHOD: One hundred and twelve untreated patients with OSAS and 19 non-apnoeic snoring subjects upon polysomnography were included in this study. Oral glucose tolerance test (OGTT) was performed in all subjects who had fasting blood glucose < 125 mg/dl. IR method was analysed using homeostasis assessment model (HOMA-IR). Diabetes mellitus (DM), impaired glucose tolerance (IGT) and impaired fasting glucose (IFG) were defined according to values of OGTT. DGM was defined as having one of the diagnoses of DM, IGT or IFG. Subjective sleepiness of all subjects was assessed with Epworth Sleepiness Scale (ESS). Excessive daytime sleepiness (EDS) was described as ESS score ≥ 10. RESULTS: Fasting glucose and the rate of DGM in patients with OSAS were higher than in non-apnoeic snoring subjects. DGM were shown in % 15.7 of non-apnoeic snoring subjects, 29.6% of mild sleep apnoea, 50% of moderate sleep apnoea and 61.8% of severe sleep apnoea. The rate of DGM in patients with moderate and severe OSAS was higher than in non-apnoeic snoring subjects and in patients with severe OSAS higher than in patients with mild OSAS. DGM are associated with body mass index (BMI), severity of OSAS, arousal index and EDS. In addition, IR is associated with apnoea hypopnoea index, BMI, arousal index and ESS score. CONCLUSION: Obstructive sleep apnoea syndrome is associated with high frequency of DGM. In addition, the progression of disease from simple snoring and mild OSAS to severe OSAS increases the rate of DGM. Thus, DGM especially in patients with severe OSAS should be examined in regular periods.

Ticks (Acari:Ixodidae) are important pests transmitting tick-borne diseases such as Crimean-Congo hemorrhagic fever (CCHF) to humans. Between 2002 and 2009, numerous CCHF cases were reported in Turkey, including Amasya province. In the current study, species diversity, seasonal abundance of ticks, and presence of CCHF virus (CCHFV) in ticks infesting humans in several districts of Amasya province were determined. In the survey, a total of 2,528 ixodid ticks were collected from humans with tick bite from April to November 2008 and identified to species. Hyalomma marginatum (18.6%), Rhipicephalus bursa (10.3%), Rhipicephalus sanguineus (5.7%), Rhipicephalus (Boophilus) annulatus (2.2%), Dermacentor marginatus (2.5%), Haemaphysalis parva (3.6%), and Ixodes ricinus (1.6%) were the most prevalent species among 26 ixodid tick species infesting humans in Amasya province. Hyalomma franchinii Tonelli & Rondelli, 1932, was a new record for the tick fauna of Turkey. The most abundant species were the members of Hyalomma and Rhipicephalus through summer and declined in fall, whereas relative abundances of Ixodes and Dermacentor ticks were always low on humans in the province. Of 25 Hyalomma tick pools tested, seven pools were CCHFV positive by reverse transcription-polymerase chain reaction. Results indicated diversity of ixodid tick species infesting humans was very high, abundance of ticks changed by season, and ticks infesting humans had potential for transmitting CCHFV.

Karyotypes of ten sections of genus Trigonella Linnaeus, 1753 (Fabaceae) from Turkey were investigated. Somatic chromosome numbers of examined species were determined as 2n=14 and 16. The karyotype analyses of the species were carried out and somatic chromosome numbers of Trigonella plicata Boiss., 1872, Trigonella brachycarpa (Fisch.) Moris, 1833, Trigonella rostrata Boiss., 1872, Trigonella lunata Boiss., 1843, Trigonella isthmocarpa Boiss. et Balansa 1856, Trigonella rhytidocarpa Boiss. et Balansa, 1859, Trigonella spicata Sibth. et Sm., 1813, Trigonella cephalotes Boiss. et Balansa 1856, Trigonella capitata Boiss., 1843 and Trigonella gladiata Steven, 1808 were reported for the first time. Two pairs of satellite metaphase chromosomes were observed in Trigonella cariensis Boiss., 1843 and one pair in Trigonella lunata.Moreover, 2 B-chromosomes were found only in Trigonella procumbens Rchb., 1830 among all studied species. The aims of this study are to provide karyological data for a significant pool of the taxa, to show differences among them in the number, size and morphology of somatic chromosomes, to verify previous reports or represent numbers which are different from those cited previously.
RESUMEN
OBJECTIVE: To investigate the effects of septoplasty on pulmonary function tests (PFTs) and bronchial hyperresponsiveness (BHR) in patients who had no previous pulmonary diseases. DESIGN: Prospective, controlled clinical trial. PATIENTS: Fourteen patients with nasal septal deviation (NSD) and 20 controls were enrolled in the study. MAIN OUTCOME MEASURES: All patients were evaluated with anterior rhinoscopy, nasal endoscopy, acoustic rhinometry (AR), visual analogue scale (VAS), PFTs, and bronchoprovocation test (BPT) on the day before surgery and 8 to 12 weeks after surgery. RESULTS: The postoperative values of forced expiratory volume in 1 second, forced vital capacity, and peak expiratory flow percentages were higher than preoperative ones, and these results were statistically significant (p = .007, p = .04, and p = .007, respectively). Nine patients had preoperative BHR, and three of them had negative BPT postoperatively. When compared with the preoperative values, there was a borderline decrease in the rate of BHR in six patients. There were significant improvements in the symptoms of left and right nasal congestion, headache, postnasal drip, and olfactory function after surgery. We found important improvement in the values of AR at right minimal cross-sectional area 1 (p = .02), left distance 1 (p = .04), and left distance 2 (p = .04) postoperatively. CONCLUSION: An improvement in both nasal symptoms and PFT values was seen after surgical treatment for NSD. We concluded that septoplasty may be considered as having favourable effects on BHR.

In this study, we evaluated the effect of ageing on treatment response by comparing two groups of patients with asthma. All asthmatic patients in the study were assessed on repeated occasions once admitted to the hospital: soon after admission (0 h), and then at 5th, 10th, 24th, 48th, 72nd hour, 7th day and in stable period. We compared two groups of patients: younger asthmatics, which had 33 younger aged <60, and elderly asthmatics, comprised of 29 elderly aged >or=60 years. The Asthma Quality of Life Questionnaire (AQLQ) was used to assess health-related quality of life in study. The increases in FEV1% values observed soon after the hospital admission (0 h), and at 5th, 10th, 24th, 48th, 72nd hour, 7th day and in stable period in younger group were similar that in elderly group. The Borg scores observed soon after the hospital admission (0 h), and 5th, 10th, 24th, 48th and 72nd hour in elderly asthmatics was usually higher than that in younger asthmatics. However, symptom scores observed in elderly asthmatics soon after the hospital admission and at 72nd hour were higher than those in younger asthmatics. Furthermore, decreases in the total AQLQ score and asthma severity score from exacerbation to stable period in both asthmatics were not different. Present study indicated that the airways obstruction, AQLQ and other diseases characteristics of younger and elderly asthmatics could improve at similar rates with treatment. In addition, similar exacerbation severity in elderly asthmatics was perceived more intense than younger asthmatics.

BACKGROUND: The purpose of this study was to clarify the correlations between the presence of comorbidities and psychological distress and health-related quality of life (HRQL). This was a population-based cross-sectional study. METHODS: Parents and grandparents of students from seven randomly selected primary schools in the city centre were asked to answer questionnaires sent by their children. All subjects were questioned for somatic diseases, psychological distress and HRQL by Health Questionnaire, Hospital Anxiety and Depression scale and short-form-12 health survey, respectively. RESULTS: Out of 5024 parents and grandparents (mean age 52.3 +/- 14.3 years, range 20-104 years) of primary school students 4605 returned the questionnaires, a figure that corresponds to the overall response rate of 91.6%. Chronic diseases substantially reduced HRQL and this effect did not differ markedly with the type of chronic disease. Association of comorbidities with psychological distress further impaired HRQL. As the number of chronic diseases was increased, HRQL and physical and mental functioning declined. The worst HRQL was observed in subjects who had five or more comorbidities associated with psychological distress. CONCLUSION: The present study indicates significant adverse effects of chronic diseases and psychological distress on HRQL in adults, the effect of psychological distress being the most important. Our results lead us to suggest that in the management of comorbidities, the detection of the presence and severity of associated psychological distress and its treatment, besides the specific treatment of comorbidities, may provide dramatic improvement in HRQL of the patients.

BACKGROUND: It has been speculated that asthma and irritable bowel syndrome may share common pathophysiological processes. AIM: To estimate the prevalence of irritable bowel syndrome in young and elderly patients with stable asthma. PATIENTS AND METHODS: Sixty-five young (age < 60 years) and 66 elderly (age > or = 60 years) stable asthmatics, and 119 age-matched healthy volunteers were enrolled. In all participants, presence of irritable bowel syndrome, quality of life and psychological status were evaluated. RESULTS: The prevalence of irritable bowel syndrome in asthmatic group was higher than that in the control group (27.5% versus 16.8%; odds ratio, 1.8 [1.0-3.4]; p=0.04). The prevalence of irritable bowel syndrome was significantly higher in young asthmatics than in age-matched healthy controls (36.9% versus 20.3%; odds ratio, 2.2 [1.0-5.1]; p=0.04) and than in elderly asthmatics (36.9% versus 18.2%; odds ratio, 0.3 [0.1-0.8]; p=0.01). Logistic regression analysis identified the younger age (odds ratio, 2.1 [1.1-3.8]; p=0.01), and the presence of asthma (odds ratio, 1.9 [1.0-3.5]; p=0.03) as independent risk factors for irritable bowel syndrome in all participants after adjusting for gender. We also found impaired quality of life to be associated with the presence of irritable bowel syndrome and asthma in all participants after adjusting for age and gender. CONCLUSION: The prevalence of irritable bowel syndrome appears to be significantly higher in young asthmatics, but not in elderly asthmatics, compared to age-matched healthy counterparts. Potential pathogenic mechanisms of higher irritable bowel syndrome prevalence in young asthmatics need to be explained by further studies.

The impaired perception of bronchoconstriction in asthmatic patients may increase the risk of severe exacerbation. To characterize the perception of bronchoconstriction in elderly asthma patients, we compared the perception in older patients with that of younger patients. To determine the influence of perception of long-standing diseases, we further evaluated the perception in early-onset elderly asthma patients and in late-onset elderly asthma patients. The study group consisted of 80 stable asthmatic patients. The patients were grouped according to their age (group 1, < 60 years, n = 37, group 2, > or = 60 years, n = 43). Each group was separated into two subgroups according to the duration of symptoms (late-onset asthma 1A and 2A, < 5 years, early-onset asthma 1B and 2B, > or = 5 years). A histamine inhalation test was performed for each patient. Dyspnea was assessed by modified Borg scale. The Borg score in forced expiratory volume in 1 sec (FEV1) reduction by 20% was determined as perception score 20 (PS20). The mean perception scores of the elderly asthmatic patients were significantly lower than those of the younger asthmatic patients (group 1, PS20 = 2.35 +/- 0.17; group 2, PS20 = 1.37 +/- 0.12, p < 0.0001). The differences of mean perception score (PS20) between early- and late-onset subgroups were insignificant (IA, 2.63 +/- 0.30 and IB, 2.07 +/- 0.16, p = 0.101; 2A, 1.36 +/- 0.19 and 2B, 1.59 +/- 0.120, p = 0.91). The mean perception scores of male asthmatic patients were significantly lower than those of female patients (p = 0.03). There was a correlation between PS20 and % FEV1 in the younger group (r = 0.392, p = 0.02), but not in the elderly group (r = 139, p = 0.375). The correlation between PS20 and PD20 in both younger and elderly group was insignificant (p > 0.05). Elderly asthmatics perceive less intense respiratory distress for a decrease of 20% in FEV1 than do younger asthmatics. This underperception of bronchoconstriction may result in a delay in medical care during an acute asthmatic episode. Thus, we strongly recommend that elderly asthmatic patients should be followed up more frequently and closely.

OBJECTIVE: Our goal was to determine the sensitivity of CT-guided closed pleural needle biopsy (CPNB) for the histopathologic diagnosis of diffuse malignant pleural mesothelioma (DMPM). MATERIALS AND METHODS: Thirty patients with DMPM were studied with CT-guided CPNB. Tumor specimens were classified according to their cell types. RESULTS: In 25 (83.3%) patients, the diagnosis was made by CT-guided CPNB. The remaining five patients were diagnosed by thoracoscopy, thoracotomy, or excisional biopsy of the chest wall mass. Pneumothorax was observed in 9.5% of patients and local seeding of tumor in 21.7% of patients who underwent CPNB. CONCLUSION: Properly performed CPNB under CT guidance may yield an increased sensitivity for the diagnosis of diffuse malignant pleural mesothelioma.
