We sought to determine the current role of mediastinoscopy in the investigation of non-lung cancer patients with mediastinal lymphadenopathy.Materials and methods: We retrospectively reviewed clinical parameters (age, gender, histological diagnosis, morbidity, mortality) of all patients without lung cancer who consecutively underwent mediastinoscopy in Hospital of Faculty of Medicine of Dicle University between June 2003 and December 2016.Results: Two-hundred twenty nine patients without lung cancer who underwent mediastino­scopy for the pathological evaluation of mediastinum during the study period were included. There were 156 female (68%) and 73 male (32%) patients. Mean age was 52.6 years (range, 16 to 85 years). Mean operative time was 41 minutes (range, 25 to 90 minutes). Mean number of biopsies was 9.3 (range, 5 to 24). Totally, 45 patients (19.6%) had previously undergone a nondiagnostic bronchoscopic biopsy such as transbronchial needle aspiration or endobronchial ultrasound-guided transbronchial needle aspiration. Mediastinoscopy was diagnostic for all patients. Diagnosis included sarcoidosis (n=100), tuberculous lymphadenitis (n=66), anthracosis lymphadenitis (n=44), lymphoma (n=11) metastatic carcinoma (n=5), and Castleman’s disease (n=1); there was a diagnosis of silicosis in one patient and tymoma in one patient. Neither operative mortality nor major complication developed. The only minor complication was wound infection which was detected in three patients.Conclusion: Although newer diagnostic modalities are being increasingly used to diagnose mediastinal diseases, mediastinoscopy continues to be a reliable method for the investigation of mediastinal lesions. Keywords: mediastinoscopy, lymphadenopathy, granulomatous diseases, mediastinum, lymph node

In tissue engineering, three-dimensional functional scaffolds with tailored biological properties are needed to be able to mimic the hierarchical structure of biological tissues. Recent developments in additive biomanufacturing allow to extrude multiple materials enabling the fabrication of more sophisticated tissue constructs. These multi-material biomanufacturing systems comprise multiple printing heads through which individual materials are sequentially printed. Nevertheless, as more printing heads are added the fabrication process significantly decreases, since it requires mechanical switching among the physically separated printheads to enable printing multiple materials. In addition, this approach is not able to create biomimetic tissue constructs with property gradients. To address these limitations, this paper presents a novel static mixing extrusion printing head to enable the fabrication of multi-material, functionally graded structures using a single nozzle. Computational fluid dynamics (CFD) was used to numerically analyze the influence of Reynolds number on the flow pattern of biomaterials and mixing efficiency considering different miscible materials.

Abstract Background Denim sandblasting is as a novel cause of silicosis in Turkey, with reports of a recent increase in cases and fatal outcomes. We aimed to describe the radiological features of patients exposed to silica during denim sandblasting and define factors related to the development of silicosis. Methods Sixty consecutive men with a history of exposure to silica during denim sandblasting were recruited. All CT examinations were performed using a 64-row multi-detector CT (MDCT). The nodules were qualitatively and semi-quantitatively analyzed by grading nodular profusion (NP) on CT images. Results Silicosis was diagnosed radiologically in 73.3% of patients (44 of 60). The latency period (the time between initial exposure and radiological imaging) and duration of silica exposure was longer in patients diagnosed with silicosis than in those without silicosis (p < 0.05). Nodules were present in all cases with centrilobular type as the commonest (63.6%). All cases of silicosis were clinically classified as accelerated and 11.4% had progressive massive fibrosis (PMF). Mild NP lesions were the most prevalent in all six zones of the lung. The NP score was significantly correlated with the duration of silica exposure, the latency period, presence of PMF, and pleural thickening. Enlarged lymphadenopathy was present in 45.5% of patients. Conclusions The duration of exposure and the latency period are important for development of silicosis in denim sandblasters. MDCT is a useful tool in detecting findings of silicosis in workers who has silica exposure.

Background: Since 2017, terminally ill parents with dependent children under the age of 18 have been able to record an audiobook for their dependent children. This service allows them to narrate how they would like to be remembered in their voice. The family audiobook is a professionally supported, voluntary, free service that is unique in Germany. There is little research on digital memories for children. The study aims to understand how this service is used and its influence on children through responses of terminally ill parents and close persons., Methods: An anonymous online survey, accessible between September 2023 and November 2023, was conducted among terminally ill parents and their close persons with support from the Family Audiobook Association in Germany. Analyses were carried out using SPSS., Results: 186 respondents, 95 terminally ill parents, and 91 close persons completed the online survey. Almost all terminally ill parents felt eased to have recorded a family audiobook. The two groups showed differences in how they used the family audiobook and how often they listened to it. While some children listen to the family audiobook with their bereaved parents or friends, other children are not yet ready for this, according to the open-ended responses of terminally ill parents and close persons., Conclusions: The family audiobook provides a valuable opportunity for terminally ill parents with dependent children under the age of 18 to tell their own biographical story, offer support to the bereaved in remembering, and preserve the voice of the deceased for the children. In addition, this approach could help healthcare professionals to reduce the stress associated with providing end-of-life care for terminally ill parents., (© 2024. The Author(s).)

Introduction: With the premise that the demanding educational process and associated factors could influence the work-related quality of life (WRQoL) of dental students, this study aimed to investigate the influence of diverse sociodemographic and health-related factors, clinical education status, and sleep quality on the WRQoL of dental students., Materials and Methods: A three-part questionnaire was administered to a group of preclinical and clinical dental students studying in different classes. The first part of the questionnaire included various sociodemographic and health-related questions. In the second part, the multidimensional 23-item WRQoL scale, with established validity and reliability, was applied to evaluate the WRQoL of the students. The last part of the questionnaire included the Pittsburgh Sleep Quality Index, comprising 19 items. General linear models were created to predict subscale scores using sociodemographic and health-related characteristics, as well as univariate significant independent variables., Results: It was observed that the majority of the participants (78.2%) had poor sleep quality. Being clinical dental students had a significant and positive effect on the stress at work domain of WRQoL (p = .006), while it had a significant and negative effect on the home-work interface domain (p < .001). The decrease in sleep quality had a significant and negative effect on all domains of WRQoL (p < .05) except for the stress at work domain., Conclusions: Clinical education status, regular smoking, and sleep quality significantly affect different domains of dental students' WRQoL. Changes in these factors should be considered in approaches to increasing students' WRQoL., (© 2024 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Background: Caring for terminally ill patients with minor children can be very stressful. The perceived quality of life is significantly influenced by the Meaning in Life (MiL). No studies were found that focus on the prioritized special needs of this patient group., Objectives: The aim is to compare and contrast terminally ill parents with minor children and palliative care patients in Germany, in order to provide appropriate support beyond medical, nursing or therapeutic interventions., Methods: Terminally ill parents diagnosed were surveyed using a validated instrument 'Schedule for Meaning in Life Evaluation (SMiLE)'. The study listed various areas that contribute to the MiL, followed by an evaluation of their importance and satisfaction levels. The researchers then compared these findings with data collected from palliative care patients., Results: In Germany, 54 patients, mostly female and with a mean age of 43, were included in this study between February 2017 and September 2020. The median age of the 96 children during the survey phase was 7 years. The comparison group consists of 100 palliative care patients in Germany; mostly aged 50 years and older. For terminally ill patients most important areas were in decreasing order family (100%), social relations (80%), leisure time (61%), nature/animals (39%) and home/garden (30%). Although the overall indices are close between both groups, there are significant and highly correlated differences between them. Parents felt limited by their illness in being a mother or father, as they wanted to be., Conclusion: The involvement with SMiLE led patients to consider their coping resources. The areas relevant to terminally ill parents differed from those relevant to palliative care patients. All participants identified family as the most important factor for MiL. The results suggest that evaluating MiL can serve as a coping strategy and help terminally ill parents with minor children., Competing Interests: The authors declare that there is no conflict of interest., (© The Author(s), 2024.)

Statement of Problem: Additive (AM) and subtractive (SM) manufacturing have become popular for fabricating occlusal devices with materials of different chemical compositions. However, knowledge on the effect of material and antagonist type on the wear characteristics of occlusal devices fabricated by using different methods is limited., Purpose: The purpose of this in vitro study was to evaluate the effect of material and antagonist type on the wear of occlusal devices fabricated by using conventional manufacturing, AM, and SM., Material and Methods: Two-hundred and forty Ø10×2-mm disk-shaped specimens were fabricated by using heat-polymerized polymethylmethacrylate (control, CM), AM clear device resin fabricated in 3 different orientations (horizontal [AMH], diagonal [AMD], and vertical [AMV]), SM polymethylmethacrylate (SMP), and SM ceramic-reinforced polyetheretherketone (SMB) (n=40). Specimens were then divided into 4 groups based on the antagonists: steatite ceramic (SC); multilayered zirconia (ZR); lithium disilicate (EX); and zirconia-reinforced lithium silicate (ZLS) used for thermomechanical aging (n=10). After aging, the volume loss (mm 3 ) and maximum wear depth (μm) were digitally evaluated. Data were analyzed with 2-way analysis of variance and Tukey honestly significant difference tests (α=.05)., Results: The interaction between the device material and the antagonist affected volume loss and maximum depth of wear (P<.001). AMH had volume loss and depth of wear that was either similar to or higher than those of other materials (P≤.044). When SC was used, CM had higher volume loss and depth of wear than AMV, and, when EX was used, AMD had higher volume loss and depth of wear than SMP (P≤.013). SC and ZR led to higher volume loss of CM and AMH than EX and led to the highest depth of wear for these materials, while ZR also led to the highest volume loss and depth of wear of AMD and AMV (P≤.019). EX led to the lowest volume loss and depth of wear of AMV and SMP and to the lowest depth of wear of AMH (P≤.021). Regardless of the antagonist, SMB had the lowest volume loss and depth of wear (P≤.005)., Conclusions: AMH mostly had higher volume loss and depth of wear, while SMB had the lowest volume loss, and its depth of wear was not affected by the tested antagonists. ZR mostly led to higher volume loss and maximum depth of wear, while EX mostly led to lower volume loss and maximum depth of wear of the tested occlusal device materials., (Copyright © 2024 Editorial Council for The Journal of Prosthetic Dentistry.

Background: Resilience is an increasingly used term in medicine and subject to various definitions, often not easy to grasp. There are established core concepts for patients receiving palliative care, for example, meaning in life, that have already been researched a lot. Resilience, relative to these concepts, is a new object of research in palliative care, where it has so far been used predominantly with regard to the well-being of teams., Aim: To explore how experts in palliative care define the concept of resilience and its suitability for patients, significant others, and professionals., Design: Qualitative study using summarizing content analysis according to Mayring., Setting/participants: Twenty-one health and social care professionals with expertise caring for persons with life-threatening/limiting illnesses and their relatives were interviewed in three individual interviews and four focus groups. All conversations were recorded, transcribed, coded via MAXQDA, and validated by another researcher., Results: Resilience has been described as something procedural, dynamic, individual, and flexible. In connection with well-known concepts such as posttraumatic growth or terms from the field of mindfulness, social environment or personal factors have also been linked to resilience. Resources such as spirituality can contribute to resilience, and resilience itself can function as a resource, for example, by contributing to quality of life. An active use of the term in practical work with patients or relatives is rare, but it is used in education or team measures. Limited lifespan can pose a challenge to an active use of the concept of resilience., Conclusion: Resilience as a very individual approach provides added value to other core concepts of palliative care. Within the palliative context, the normative dimension of resilience must be well reflected. A broader definition of resilience is recommended, leaving room for everyone to find their own form of resilience. The concept of resilience in palliative care includes opportunities as well as risks and should, therefore, be implemented carefully, requiring specific training., Competing Interests: The authors declare that there is no conflict of interest., (© The Author(s), 2024.)

Background: Structures of palliative care, cross-sectoral transitions and care pathways of patients with palliative care needs were investigated at two sites. The systematic comparison of similarities and differences using the topic of 'pain' as an example is intended to provide information on the extent to which these are related to site-specific palliative care concepts (integrated and cooperative)., Methods: The study follows a mixed-methods design. In addition to a document analysis of anonymised patient records (n = 774), expert interviews (n = 20), as well as interviews with patients, relatives (n = 60) and focus groups (n = 12), were conducted., Results: The systematic comparative analysis provides evidence for concept-independent commonalities (e.g. sociodemographic distribution, aggravated pain treatment) as well as concept-dependent differences (e.g. care pathways, facilitated continuous symptom control through integrated care structures) in the context of integrated or cooperative palliative care., Discussion: Commonalities and differences with regard to the topic of pain, as focused on here, and its organisational management become tangible as effects of the respective organisational structure (= concept-dependent) as well as concept-independent external influencing factors., (© 2023.

Anomalies, which are incompatible with the efficient market hypothesis and mean a deviation from normality, have attracted the attention of both financial investors and researchers. A salient research topic is the existence of anomalies in cryptocurrencies, which have a different financial structure from that of traditional financial markets. This study expands the literature by focusing on artificial neural networks to compare different currencies of the cryptocurrency market, which is hard to predict. It aims to investigate the existence of the day-of-the-week anomaly in cryptocurrencies with feedforward artificial neural networks as an alternative to traditional methods. An artificial neural network is an effective approach that can model the nonlinear and complex behavior of cryptocurrencies. On October 6, 2021, Bitcoin (BTC), Ethereum (ETH), and Cardano (ADA), which are the top three cryptocurrencies in terms of market value, were selected for this study. The data for the analysis, consisting of the daily closing prices for BTC, ETH, and ADA, were obtained from the Coinmarket.com website from January 1, 2018 to May 31, 2022. The effectiveness of the established models was tested with mean squared error, root mean squared error, mean absolute error, and Theil's U1, and R OOS 2 was used for out-of-sample. The Diebold-Mariano test was used to statistically reveal the difference between the out-of-sample prediction accuracies of the models. When the models created with feedforward artificial neural networks are examined, the existence of the day-of-the-week anomaly is established for BTC, but no day-of-the-week anomaly for ETH and ADA was found., Competing Interests: Competing interestsThe authors declare that they have no competing interests., (© The Author(s) 2023.)

Background: Interventions addressing pain and impaired functionality in individuals with temporomandibular disorders (TMDs) are needed., Objective: To compare the effects of 4 weeks of exercise combined with ischaemic compression and exercise alone in patients with TMDs., Methods: Fifty patients who were diagnosed with TMDs were randomised into Group 1 (exercise combined with ischaemic compression technique) (n = 25) or Group 2 (exercise alone) (n = 25). Both groups performed 4 weeks of Rocabado's exercise and 3 weeks of postural exercise, while Group 1 received ischaemic compression to the masseter muscle for a total of 3 sessions in addition to exercise. A ruler was used to assess range of motion (ROM) (painless mouth opening (PMO), maximum mouth opening, maximum assisted mouth opening (MAMO), left lateral movement and right lateral movement), the visual analogue scale and graded chronic pain scale were used to assess pain, an algometer was used to determine the pain pressure threshold (PPT), and the 8-item jaw functional limitation scale was used to assess, functionality. The assessments were performed at baseline, at week 1 and at week 4., Results: The participants in Group 1 exhibited larger PMO (F = 5.26, P = .02) and MAMO values (F = 6.71, P = .01) than did the patients in Group 2 at week 1. The effect size was small for MAMO (ES = 0.27) and moderate for PMO (ES = 0.51). However, there were no significant differences in any other outcomes between groups at week 1 or 4., Conclusion: In summary, this randomised controlled trial indicates that exercise combined with ICT and exercise alone have similar effects on ROM, pain, the PPT and functionality in patients with TMDs., (© 2021 John Wiley & Sons Ltd.)

It has been more than 3 months now since the first case of COVID-19 was reported in Turkey. Globally, the number of confirmed cases and deaths reached 9,653,048 and 491,128 respectively, as reported by 216 countries by June 27, 2020. Turkey had 1,396 new cases, 194,511 total cases, and 5,065 deaths by the same date. From the first case until today, the Turkish Thoracic Society (TTS) has been very proactive in educating doctors, increasing public awareness, undertaking academic studies, and assisting with public health policies. In the present report, social, academic, and management perspectives of the pandemic are presented under appropriate subtitles. During this critical public health crisis, TTS has once again demonstrated its readiness and constructive stance by supporting public health, healthcare workers, and the environment. This review summarizes the perspective of TTS on each aspect of the COVID-19 pandemic and casts light on its contributions.

Increasing interest has been observed in the use of photobiomodulation (PBM) to enhance the proliferation of stem cells and induce their differentiation. The effects of PBM at two different wavelengths (635 and 809 nm) with three different energy densities (0.5, 1 and 2 J/cm 2 ) on the osteogenic differentiation of adipose-derived stem cells (ADSC) were investigated. Cell viability and proliferation were evaluated by MTT and Alamar Blue assays. Osteoblast differentiation were assessed by alkaline phosphatase (ALP) activity, Alizarin red staining and reverse-transcription polymerase chain reaction (RT-PCR) for the expression of collagen type I (COL1A), ALP and osteocalcin. 635 nm and 809 nm laser irradiation had no effect on the cell viability on days 7 and 14, except for 0.5 J/cm 2 group at 14th day after 635 nm irradiation (p < 0.05). Cell proliferation was not changed significantly. Mineralization was increased significantly in 809 nm laser groups but no enhancement was detected in the osteogenic differentiation by ALP activity and gene expression results. In 0.5 and 1 J/cm 2 groups, ALP and COL1A expressions were down regulated at day 7 after 809 nm laser exposure. These results suggest that PBM may alter osteogenic differentiation of ADSC and increase mineralization but further investigation is needed to define adequate parameters.

Objectives: We aimed to obtain information about the characteristics of the ICUs in our country via a point prevalence study., Material and Methods: This cross-sectional study was planned by the Respiratory Failure and Intensive Care Assembly of Turkish Thoracic Society. A questionnaire was prepared and invitations were sent from the association's communication channels to reach the whole country. Data were collected through all participating intensivists between the October 26, 2016 at 08:00 and October 27, 2016 at 08:00., Results: Data were collected from the 67 centers. Overall, 76.1% of the ICUs were managed with a closed system. In total, 35.8% (n=24) of ICUs were levels of care (LOC) 2 and 64.2% (n=43) were LOC 3. The median total numbers of ICU beds, LOC 2, and LOC 3 beds were 12 (8-23), 14 (10-25), and 12 (8-20), respectively. The median number of ventilators was 12 (7-21) and that of ventilators with non-invasive ventilation mode was 11 (6-20). The median numbers of patients per physician during day and night were 3.9 (2.3-8) and 13 (9-23), respectively. The median number of patients per nurse was 2.5 (2-3.1); 88.1% of the nurses were certified by national certification corporation., Conclusion: In terms of the number of staff, there is a need for specialist physicians, especially during the night and nurses in our country. It was thought that the number of ICU-certified nurses was comparatively sufficient, yet the target was supposed to be 100% for this rate.

Background: Family carers manage a wide range of responsibilities in the lives and care of patients receiving palliative care. They fulfil multiple roles and perform activities within different settings. This has immediate consequences on family carers' every-day lives. According to literature, family carers in palliative care are both part of the formal and informal care network, but also persons in need of support. This article aims to investigate 1) burdens and rewards associated with family caregiving and 2) what family carers find helpful in their contact with professionals from integrated palliative care initiatives (IPC-i) and other services., Methods: Family carers looking after patients with cancer, chronic obstructive pulmonary disease or chronic heart failure were purposefully recruited at 22 IPC-i in Belgium, Germany, Hungary, the Netherlands and the United Kingdom in the course of the project "Patient-centred palliative care pathways in advanced cancer and chronic disease" (InSup-C). Semi-structured interviews (n = 156) and 87 quantitative questionnaires (CRA, POS, CANHELP Lite) were conducted with family carers. Interviews were analysed with transnationally agreed thematic codes (MAXQDA or NVivo). Statistical tests (SPSS) were carried out in accordance with the characteristic value of the items and distributions., Results: On average, quantitative data showed moderate burden, but the qualitative findings indicated that this burden might be underrated. There is some evidence that IPC-i with well-developed professional care networks and communication systems relieved family carers' burden by direct and indirect interventions; e.g. provision of night shift nurses or psychological support. Needs of family carers were similar in all participating countries. However, in all countries IPC-i mostly offered one-off events for family carers, lacking systematic or institutionalised support structures., Conclusions: Data suggest that, most IPC-i did not pay enough attention to the needs of most family carers, and did not offer proactive care and access to supportive resources to them (e.g. training, respite care, access to resources). We recommend recognizing family carers as part of the 'unit of care' and partner in caregiving, to improve their knowledge about, and access to, and the support available.

Background: Blunt thoracic injury often leads to pulmonary contusion and the development of acute respiratory distress syndrome, which carries a high risk of morbidity and mortality, originating from the local and systemic inflammatory states. This study aimed to investigate the local and systemic antiinflammatory effects of levosimendan in rat models of blunt chest trauma., Methods: A total of 32 Wistar albino rats were randomly assigned to one of the following four groups: control, sham, low-dose levosimendan (LDL) (5 µg/kg loading dose for 10 min and 0.05 µg/kg/min intravenous infusion), and high-dose levosimendan (HDL) (10 µg/kg loading dose for 10 min and 0.1 µg/kg/min intravenous infusion). Blunt chest trauma was induced, and after 6 h, the contused pulmonary tissues were histopathologically and immunohistopathologically evaluated, serum TNF-α, IL-1ß, IL-6, and NO levels were biochemically evaluated., Results: The mean arterial pressure was low throughout the experiment in the LDL and HDL groups, with no statistically difference between the groups. Levosimendan reduced the alveolar congestion and hemorrhage, which developed after inducing trauma. Neutrophil infiltration to the damaged pulmonary tissue was also reduced in both the LDL and HDL groups. In rats in which pulmonary contusion (PC) was observed, increased activation of nuclear factor kappa B was observed in the pulmonary tissue, and levosimendan did not reduce this activation. Both high and low doses of levosimendan reduced serum IL-1ß levels, and high doses of levosimendan reduced IL-6 and NO levels. TNF-α levels were not reduced., Conclusion: In conclusion, the results showed that in a rat model of PC, the experimental agent levosimendan could reduce neutrophil cell infiltration to damaged pulmonary tissues and the systemic expressions of some cytokines (IL-1ß, IL-6, and NO), thereby partially reducing and/or correcting pulmonary damage. Systemic inflammatory response that occurs after trauma could also be reduced.

Photobiomodulation (PBM) describes light-induced photochemical reactions achieved by the application of red or near infrared lasers/LED light with low energy densities. This noninvasive and painless method has been used in some clinical areas but controversial outcomes demand a skeptical look for its promising and potential effects. In this detailed in vitro study, the osteoblast cells were irradiated with 635 and 809 nm diode lasers at energy densities of 0.5, 1, and 2 J/cm 2 . Cell viability, proliferation, bone formation, and osteoblast differentiation were evaluated by methylthiazole tetrazolium (MTT) assay, Alamar Blue assay, acridine orange/propidium iodide staining, alkaline phosphatase (ALP) activity, Alizarin red staining, and reverse-transcription polymerase chain reaction (RT-PCR) to test the expression of collagen type I, ALPL, and osteocalcin. The results indicate that studied energy doses have a transient effect (48 h after laser irradiation) on the osteoblast viability and proliferation. Similarly, laser irradiation did not appear to have any effect on ALP activity. These results were confirmed by RT-PCR analysis of osteoblast markers. This study suggests that several irradiation parameters and variations in the methods should be clearly established in the laboratory before laser treatment becomes a postulated application for bone tissue regeneration in clinical level.

Objective: To assess relationship between alexithymia and acne vulgaris in young people., Methods: A hundred and eleven subjects between 15 and 25 years of age referred to out-patient clinic of dermatology with acne and 78 subjects applied to family physician for complaints other than acne were included in patient and control groups of the study, respectively. A questionnaire to determine demographic characteristics, an acne classification to determine severity of acne and Toronto Alexithymic Scale (TAS) to assess alexithymia were used., Results: The mean scores of TAS were 52.7±10.8 and 51.7±10.7 in patient and control groups, respectively. Alexitymia was determined in 23.4% of the subjects in acne group and in 24.4% of control group. No significant differences were found between groups in terms of alexithymia, intermediate alexitymia and three-factors of TAS., Conclusion: Alexithymia does not appear to be related to acne vulgaris.

The aim of this study was to estimate the quality of life, depression and anxiety in patients with silicosis due to denim sandblasting. This study was conducted on 50 young male patients with silicosis and 30 controls. A socio-demographic data form, Short Form-36 (SF-36), the Beck depression inventory (BDI) and the Beck anxiety inventory (BAI) were used to determine quality of life, depression and anxiety. The mean scores of SF-36, BDI and BAI were higher in the patients than in the controls. Correlation analysis revealed a strong negative correlation between all scales of SF-36 and BDI scores. Additionally, there was strong negative correlation between five scales of SF-36 and BAI scores. We suggest that silicosis might be detrimental to the quality of life and increase depression and anxiety in patients with silicosis due to denim sandblasting.

The present study examined the effects of illness representation, perceived quality of information provided by the health-care professional, and perceived social support on the depressive symptoms of the caregivers of children with leukemia. The sample was composed of 71 caregivers of children with leukemia living in Turkey. The obtained data were analyzed by path analysis. The results show that caregivers of children with leukemia experience higher levels of depressive symptoms when they have negative illness representation and lower levels of depressive symptoms when they perceive higher levels of social support. Moreover, they perceive higher social support when they perceive high quality of information provided by health-care professionals. It can be suggested that intervention programs which aim to increase caregivers' social support and change their illness representation in a positive way would be helpful for the caregivers showing depressive symptoms.

Objectives: The aim of this study was to investigate the effect of topical mitomycin-C application before or after incisional myringotomy on patency times and to asess its use as an alternative to ventilation tube insertion., Materials and Methods: Nineteen guinea pigs were divided into two groups. In the study group (n=11), mitomycin-C was applied in a concentration of 0.4 mg/ml over the perforation for five minutes before (n=6) or after (n=5) incisional myringotomies in both ears. Control animals (n=8) received 0.1 ml 0.09% NaCl for the same duration. Evaluations were made on days 1, 3, 5, 7, 10, 14, and 21. The patency times, otorrhea, and other complications were recorded., Results: Compared to controls (7.0+/-1.5 days), the mean patency times of perforations were significantly longer in mitomycin-C treated groups before (11.6+/-5.2 days) and after (14.2+/-4.7 days) incisional myringotomies (p<0.05). Patency times did not differ significantly between the two mitomycin-C groups. None of the ears exhibited permanent perforation., Conclusion: The length of patency provided by mitomycin-C is not sufficient for optimal ventilation in otitis media with effusion. However, in cases requiring shorter patency times, mitomycin-C application before or after myringotomy may be an alternative to ventilation tube insertion.

Objectives: The effect of topical N-acetylcysteine (NAC) application was investigated on the healing of acute experimental tympanic membrane perforations., Materials and Methods: Twenty guinea pigs were used in this study. Under intraperitoneal ketamine anesthesia, incisional myringotomies were performed in the posterosuperior quadrant of the tympanic membranes with a straight otologic hook. The diameter of the perforations was approximately 2 mm. Perforations in both ears were treated with freshly prepared sponges soaked in either 0.1 ml 0.9% NaCl solution (10 control animals) or 0.6 mg/0.1 ml NAC (10 animals) for three consecutive days. All the tympanic membranes were examined by otomicroscopy on the third, fifth, seventh, and ninth days., Results: In the control group, all the perforations were completely closed at the end of nine days. During the same period, only 40% of the perforations were completely closed in the NAC group. The remaining ears exhibited otorrhea by the third day., Conclusion: N-acetylcysteine may cause severe otorrhea in the healing process of tympanic membrane perforations. Further studies including histopathological examinations are required to elucidate this condition.

Objectives: We investigated the effect of topical application of 5-fluorouracil after incisional myringotomy on the patency time and its use as an alternative to ventilation tube insertion., Materials and Methods: Experimental tympanic membrane perforations were induced in two groups of guinea pigs. One group (20 tympanic membranes) was treated with a 50 mg/ml 5-fluorouracil-soaked sponge over the perforation for five minutes while the other (16 tympanic membranes) with saline-soaked sponges for the same duration. The patency times, otorrhea, and other complications were recorded., Results: The mean patency of tympanic membrane perforations following incisional myringotomy was significantly longer in the 5-fluorouracil-treated group (11.3 days vs 7.0 days; p<0.01). None of the ears exhibited permanent perforation., Conclusion: The length of patency provided by 5-fluorouracil is not sufficient for optimal ventilation time in otitis media with effusion. However, in circumstances in which shorter patency times may provide sufficient ventilation, 5-fluorouracil application may be an alternative to ventilation tube insertion.

Objectives: The aim of this study was to compare the usefulness of nasal smear eosinophilia with skin prick test for the diagnosis of allergic rhinitis and to determine the degree of correlation between the tests., Patients and Methods: Forty-one patients (16 males, 25 females; mean age 35.17; range 14 to 56 years) with a clinical history suggestive of nasal allergy and fifteen controls (7 males, 8 females; mean age 27.6; range 16 to 40 years) without any history of allergy were enrolled in this study. Skin sensitivity tests were applied in both groups. Nasal smear was examined by light microscopy., Results: A positive skin test reaction was demonstrated in 73.2% of the study group and in 20% of the controls, whereas 73.2% of the patients and 13.3% of the controls demonstrated significant nasal smear eosinophilia. There was 25.5% correlation between the skin prick test and nasal smear eosinophilia, although this was not statistically significant., Conclusion: Both the skin prick test and nasal smear eosinophilia showed correlation with clinical history, but there was no statistically significant correlation between the two tests.

Primary hyperparathyroidism is a rare disease of childhood. The condition is even rarer in the neonatal and infant stages. The disease, with its main manifestation-hypercalcemia-often is fatal. The authors successfully treated a 2.5-month-old boy who had primary parathyroid hyperplasia. The patient had recurrent pneumonia and failure to thrive. Blood test results showed an abnormally high level of calcium, which was resistant to medical therapy. Further investigations showed high levels of parathyroid hormone. The patient underwent neck exploration, which showed hyperplasia of the all four parathyroid glands. Total parathyroidectomy was performed, with one gland being autotransplanted to the deltoid muscle. The patient had an immediate hypocalcemic period, followed by normocalcemia. In light of the present case and others in the Literature, the authors recommended total parathyroidectomy followed by autotransplantation of a gland to an accessible muscle.
