Abstract
BACKGROUND Growing-rod (GR) treatment is the current standard for progressive idiopathic early-onset scoliosis (I-EOS) in young children. Despite good radiographic outcomes, the impact of scoliosis treatment on pulmonary functions is not well-defined in this patient population. The aim of this study was to evaluate pulmonary functions and exercise tolerance in I-EOS patients graduated from GR treatment and to compare them with age-matched, surgically treated adolescent idiopathic scoliosis (AIS) patients and healthy controls. METHODS Eight GR graduates with I-EOS with pulmonary function tests and complete radiographic results were compared with a group of 9 thoracic AIS patients at least 2 years out from posterior fusion. Both groups were also compared with a set of 10 healthy individuals. All subjects underwent cardiopulmonary exercise testing and spirometry to evaluate pulmonary function. RESULTS Age, sex, height, arm span, weight, residual deformity, and level of instrumentation in GR and AIS patients were similar. In the GR group, forced vital capacity % and forced expiratory volume in 1 second % values were reduced compared with the healthy controls and AIS group (P<0.001, <0.001 and 0.036, 0.046, respectively). Breathing reserve index at lactate threshold (BRILT) was higher in GR and AIS patients (P=0.001 and 0.002, respectively), and was similar between GR and AIS patients (P=0.916). Heart rate at lactate threshold was higher in GR and AIS groups compared with controls (P<0.001 and 0.001, respectively). CONCLUSIONS AIS and GR patients demonstrated reduced pulmonary reserve and exercise tolerance compared with their peers with no spinal deformity. However, exercise tolerance of I-EOS patients treated with the GR method was similar to that of operated AIS patients. These results suggest a positive impact of GR treatment in children with I-EOS. LEVEL OF EVIDENCE Level III-cross-sectional comparative study.

Abstract
OBJECTIVES Prior studies have been performed on cotton textile plants throughout the world. This study was planned to identify the rate of byssinosis and chronic obstructive pulmonary disease (COPD) in hemp and jute workers and those who worked with both of them. MATERIAL AND METHODS The study was realized in a factory which consecutively processed hemp and jute. The study enrollment included 266 people, 164 of whom were active workers and 102 were retired. A questionnaire, plain chest X-rays, physical examination and pulmonary function tests were performed. Dust levels were measured in various sections of the factory during 8 h work shifts. Endotoxin levels of various quality hemp fibers and dusts were measured. RESULTS The rate of byssinosis (28.2%) was higher among the workers that who exposed to both jute and hemp dust. The frequency of chronic bronchitis in retired workers who previously smoked was higher (20%) as compared to currently smoking workers (17%). High dust levels were measured in some parts of the factory (mean (M) = 2.69 mg/m3). Working in dense dust areas, active smoking, being older than 40 years of age, being an ex-smoker, and working in the factory for a period exceeding 15 years were significantly associated with bronchitis and emphysema development. High endotoxin levels were determined for fine hemp dust (605 EU/mg), coarse hemp dust (336 EU/mg) and poor quality hemp fibers (114 EU/mg), whereas in fresh hemp stalks the level of endotoxin was determined to be lower (0.27 EU/mg). CONCLUSIONS Because of high exposures to jute and hemp dusts that are associated with high byssinosis rates, personal protection and environmental hygiene is crucial to prevention of byssinosis.

Abstract
OBJECTIVE Uric acid (UA) is the end product of adenosine triphosphate degradation, and could increase due to hypoxia. We investigated the association of UA metabolites with nocturnal hypoxemia, apnea-hypopnea index (AHI), noninvasive mechanical ventilation (NIMV) usage and five-year mortality. MATERIALS/SUBJECTS AND METHODS We obtained urinary specimen before and after the night polysomnography in order to measure UA excretion and overnight change in urinary UA/creatinine ratio (ΔUA/Cr) in 75 subjects (14 controls, 15 chronic obstructive pulmonary disease (COPD) without nocturnal hypoxemia (NH), 15 COPD with NH, 16 obstructive sleep apnea syndrome (OSAS) without NH, 15 OSAS with NH). Percentage of time spent below SaO2 of 90% (T90%) for >10% of sleep time was considered as nocturnal hypoxemia. Patients were contacted after 5 years with a questionnaire including information on the use of NIMV treatment (n: 58) and urinary specimen analysis (n: 35). RESULTS T90% was found to be significantly correlated with UA excretion (coefficient: 0.005, 95%CI: 0.003-0.007) and ΔUA/Cr (coefficient: 0.8, 95%CI: 0.3-1.2) after adjustments for age, gender, body mass index and apnea-hypopnea index. Median and IQR (interquartile range) of baseline UA excretion were 0.79 (0.51-0.89) and 0.41 (0.31-0.55) in 10 deceased and 58 surviving patients, respectively (p=0.001). UA excretion median and IQR of baseline and 5 years of NIMV treatment were 0.41 (0.36-0.57) and 0.29 (0.23-0.37), respectively (p=0.01). CONCLUSION UA excretion, as a marker of tissue hypoxia, may be useful in the management of OSA and COPD patients.

Are chronic urticaria, analgesic intolerance and seasonal rhinitis markers of different severities and phenotypes of the asthma they accompany? Allergol Immunopathol (Madr) 2010; 38:313-20. [PMID: 20542623 DOI: 10.1016/j.aller.2010.01.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2009] [Revised: 01/24/2010] [Accepted: 01/26/2010] [Indexed: 11/30/2022]
Abstract
BACKGROUND Asthma is a heterogeneous disease that presents with different clinical phenotypes. We aimed to compare the patients with asthma diagnosis alone with the patients, who, in addition to their asthma had accompanying analgesic intolerance (AI), chronic urticaria (CU) or seasonal rhinitis (SR) if there are any distinctions and specific characteristics of these defined patient groups. METHODS Eighty-four asthma patients diagnosed with SR, 46 with CU, 75 with AI and 71 patients with asthma alone were enrolled to the study retrospectively. The reference group for the comparisons was the group with asthma diagnosis alone. RESULTS The mean age of all patients was 37.2±13 (15-80) and 70.7% of them were females. Asthma patients with SR had a significantly earlier onset of asthma (age: 27.4±10.8 and 34.5±15.9; respectively, p<0.01), significantly better pulmonary function tests and were significantly more atopic (92.9% and 28.8%; p<0.001). Moderate-to-severe asthma significantly correlated with older age at the time of diagnosis, older age of asthma onset, higher body mass index, less atopy and fewer pollen sensitivity. Asthma severity of patients with SR was significantly milder than the reference group (OR: 0.6, 95% CI 0.5-0.8). Asthma with AI tended to be more severe although the relation was insignificant (OR:1.6 95% CI:0.8-3.5). CONCLUSIONS Asthma patients with SR have significantly milder and earlier onset of asthma, better pulmonary function tests and are significantly more atopic while asthma with AI tends to be more severe. Asthma with CU does not show a specific phenotypic characteristic.

Abstract
BACKGROUND Information about change in the prevalence of asthma and allergic diseases and factors related with these diseases would be beneficial in decreasing the burden of these diseases. OBJECTIVE To assess (i) change in prevalence of asthma and allergic diseases; (ii) factors associated with asthma and wheeze; and (iii) incidence of asthma and wheeze. METHODS A questionnaire was administered to children aged 7-12 years in first five grades in the same primary school in 1992 (n: 1036), 1997 (n: 738), 2002 (n: 621), and 2007 (n: 422) and filled by the parents. A second survey in 2007 (n: 474, in eight grades) was conducted in the same schoolchildren, 6 months apart, to assess the incidence of asthma and wheeze and the associated factors. RESULTS Comparison of 1992, 1997, 2002, and 2007 surveys revealed that prevalence of asthma (8.3%, 9.8%, 6.4%, 3.3%, respectively), wheeze (11.9%, 13.3%, 6.4%, 3.1%, respectively), hay fever (15.4%, 14.1%, 7.2%, 3.1%, respectively), and eczema (4.0%, 4.3%, 1.8%, 1.2%, respectively) were significantly lower in 2002 and 2007 compared with that in 1992. Percentage of passive smoking decreased after 1992 (74.0%, 64.0%, 64.1%, and 65.5%, respectively). Incidence of asthma and wheeze in 2007 surveys were 0.9/100 and 1.1/100, respectively. After the adjustment for age and gender, infection in the past, family atopy, and presence of atopic disease (eczema or hay fever) were associated with asthma and wheeze. Maternal smoking and lack of breast feeding were associated with asthma. Male gender, pet ownership in the past, lack of health insurance coverage, snoring, and wood or coal used as fuel were associated with wheeze. CONCLUSIONS Decreased prevalence of asthma and allergic diseases in the last 10 years could be related to decreased rate of passive smoking. Lower socioeconomic status and lack of breast feeding could increase the risk of asthma in children.

Abstract
Neuropsychological deficits are among the main symptoms of obstructive sleep apnea syndrome (OSAS), which could be related to impaired cerebral blood flow (CBF). We conducted a study in 20 subjects tested in our Sleep Laboratory, to assess regional CBF and cognitive function in OSAS. Our measurements included technetium-99m hexamethylamino propylenamine oxime brain perfusion scintigraphy in wakeful state, i.e. in the morning after polysomnography and also cognitive function tests after polysomnography, in 20 patients, 16 male and 4 female, aging between 30 and 60 years. We found that apnea-hypopnea index was greater than or equal to 5 in 16 (85%) subjects, consistent with OSAS. Mean arterial oxygen saturation during sleep was correlated with CBF in all regions. Cognitive function test scores in verbal memory were positively correlated with percentage of sleep duration with less than 90% of oxygen saturation during sleep. Cerebral blood flow was not uniform in OSAS patients, and was significantly lower in the left frontal and left temporal regions as compared to that of these regions on the right hemisphere. In conclusion, our findings indicated association of CBF and verbal memory with hypoxemia during sleep and decreased perfusion after apneic episodes in the left frontal and temporal lobes in OSAS patients, which could also indicate impairment of upper airway motor control.

Abstract
BACKGROUND The coexistence of allergic diseases and chronic urticaria (CU) is not uncommon. Our aim was to show the prevalence of allergic diseases in chronic urticaria patients and whether possible risk factors precipitate the development of these conditions. METHODS The data of 953 patients diagnosed with CU in our adult allergy clinic between January 1991 and June 2006 were retrospectively evaluated. RESULTS The mean ages of the CU patients with and without non-steroidal anti-inflammatory drug hypersensitivity (NSAIDH) were 39.0 +/- 11.8 and 36.7+/- 12.3, respectively (p = 0.014). There was a female predominance in both groups (74.6 and 68.2%, respectively, p = 0.06). Apparently, some conditions occurred significantly more often in CU patients with NSAIDH compared to those without NSAIDH: 16.4 and 8.4% for asthma (p < 0.001), 4.2 and 0.8% for nasal polyps (p < 0.01), 20.8 and 7.3% for antibiotic hypersensitivity (p < 0.001), 21.6 and 12.3% for metal sensitization (p < 0.01), and 8 and 0.6% for familial NSAIDH (p < 0.001), respectively. Dermographism was more common in CU patients without NSAIDH compared to those with NSAIDH (29.4 and 21.2%, respectively; p < 0.05). NSAIDH increased the risk of asthma and rhinitis development [odds ratios: 52.9 (18.1-154.6) and 5.2 (2.0-13.4)]. CONCLUSION Based on our data, the incidence rates of asthma, nasal polyps, antibiotic hypersensitivity, metal sensitization and familial NSAIDH are increased in patients with CU with NSAIDH compared to those with CU only. Coexistence of NSAIDH and CU increases the risk of developing asthma and rhinitis.

Abstract
We investigated prevalence and determinants of asthma and allergic diseases in a cross-sectional survey of schoolchildren aged 6-14 in 2002. This was the third of a series of cross-sectional surveys, conducted in 1992 and 1997, in the same school in Ankara, Turkey. Questionnaire including information on house characteristics, dietary habits, past and current exposures and diseases were distributed to 1064 children (523 boys, 541 girls) and filled by the parents at home. Percentage of children having a pet was significantly higher (1992: 7.9, 1997: 22.9, 2002: 21), but that of passive smoking was significantly lower (1992: 74, 1997: 64, 2002: 64.1) in 1997 and 2002 when compared with 1992. Current prevalence percentage of asthma (1992: 8.3, 1997: 9.8, 2002: 6.4), wheeze (1992: 11.9, 1997: 13.3, 2002: 6.4), hay fever (1992: 15.4, 1997: 14.1, 2002: 7.2), and eczema (1992: 4, 1997: 4.3, 2002: 1.8) were significantly lower in 2002 compared with 1992. Multiple logistic regression analysis model for current wheeze included ingestion of cow's milk (no regular ingestion: reference, ORs and 95% CIs, <1 glass/day: 0.5, 0.3-1.0; at least 1 glass/day: 0.3, 0.2-0.7), ingestion of red meat (2.2, 1.2-3.8), and currently holding a dog (6.1, 1.6-23.4). Multiple logistic regression analysis model for current hay fever included ingestion of red meat (1.8, 1.1-2.9) and father's education (none of the parents finished secondary school: reference, secondary school to university: 0.5, 0.2-1.0). Our findings suggested that current prevalence of asthma and allergic diseases decreased among schoolchildren in Ankara, in the last 10 yr, and ingestion of milk and red meat could have a role in the occurrence of asthma and hay fever. Detailed assessment of dietary habits is required to test this hypothesis.

Abstract
Both asbestos and erionite related malignant pleural mesothelioma (MPM) is a serious health problem in Turkey. Erionite has a higher potency in the lung than asbestos and familial clustering of malignant mesothelioma suggests a genetic predisposition to this cancer among affected individuals. Neither Simian virus 40 (SV40) nor human herpes virus 8 (HHV-8) are co-factors in the pathenogenesis of environmentally induced mesothelioma. A survival advantage has been demonstrated in patients with asbestos-induced mesothelioma compared with erionite-induced mesothelioma. This together with the proliferation index (PI) can be used as an independent prognostic factor for patients with malignant pleural mesothelioma. It is envisaged that the application of these prognostic approaches together with the new TNM staging system will allow investigations to be more precisely carried out and evaluated.

Abstract
BACKGROUND Turkey is one of the four major producers of rose. Cultivation of rose is the main economic activity of many villagers in the Lakes region. Rose allergy has not been reported before. We investigated the prevalence of allergy symptoms and specific-IgE immune response due to rose in villagers who had been cultivating rose in Güneykent village in the Lakes region. METHODS A screening questionnaire including respiratory and allergic symptoms was administered to 290 villagers. The investigation team visited and studied 75 randomly selected villagers with an interviewer-administered questionnaire, pulmonary function testing, skin prick testing and serum total IgE. Specific IgE against Rosa rugosa was measured in 41 villagers. RESULTS Villagers reported asthma/allergy symptoms outside the rose season (17.6%), during the rose season (6.2%), and both during the rose season and outside the rose season (whole the year) (17.6%). Atopy and specific IgE against Rosa rugosa were detected in 12 (19%), and 8 (19.5%) of the villagers tested. Villagers who had symptoms whole the year reported wheeze more frequently than those who reported symptoms only outside the rose season (41.2% vs 11.1%). CONCLUSIONS IgE-mediated allergy could occur due to rose and/or its pollen. Symptoms mainly affect the upper airways. Further studies in the rose handlers, florists and workers of the rose industry would help elucidate the occurrence of rose allergy.

Abstract
BACKGROUND prevalence of asthma and allergic diseases is increasing worldwide. We investigated the first-year university students to a) determine prevalence of asthma, and allergic diseases, b) compare prevalence with a similar study conducted in 1994, and c) investigate determinants of asthma, current wheeze and seasonal rhinitis. METHODS an ECRHS based questionnaire was distributed to 5,406 students and completed by 4,639 (response: 85.3 %) in september 1999. Information from the students residing in Turkey was used in the analyses (1,800 boys, 2,712 girls). RESULTS prevalence % of asthma (symptom and/or medicine), current wheeze and seasonal rhinitis were 2.1, 6.9 and 12.7 in boys, and 2.5, 7.2 and 14.5 in girls. Current smoking, pet ownership and family atopy was reported more frecuently in 1999 than 1994. Cough and seasonal rhinitis increased almost twofold. Asthma diagnosis and attack rate was similar in 1999 and 1994. Family atopy, pet in childhood, smoking and passive smoking in childhood increased the risk of asthma, and current wheeze. Family atopy, passive smoking and current pet ownership increased the risk of seasonal rhinitis. CONCLUSION increased rate of smoking and pet ownership could contribute to the increased prevalence of asthma and allergic diseases in the last 5 years.

Abstract
BACKGROUND Analgesic intolerance (AI) sometimes appear alone and sometimes with bronchial asthma affecting about 10% of asthmatics and sometimes before and the other times after asthma. OBJECTIVE We investigated the possible clinical risk factors which might be affecting the transition from isolated AI to analgesic induced asthma (AIA). METHODS A total of 344 patients admitted to Hacettepe University Hospital Adult Allergy Unit between January 1991 and March 1999 and diagnosed with AI were enrolled in this survey. Patients having AIA (group I) (n = 191) were compared with the patients having AI without asthma (group II) (n = 153). The diagnosis of AI and AIA were made by history and oral provocation tests. A standard questionnaire was filled-in for all the patients. RESULTS The risk of AIA was increased with nasal polyp, and rhinosinusitis via OR's of 2.75 (95% CI: 1.09, 6.91), and 18.58 (95% CI: 9.86, 35.01), respectively. Having a pet, and ever smoking decreased the risk of AIA in the patients with AI via OR's of 0.53 (95% CI: 0.24, 1.17), and 0.37 (95% CI: 0.17, 0.80), respectively. The association of AIA and smoking was slightly modified by food intolerance (OR for ever smoked and food intolerance: 1.31, 95% CI: 0.40, 4.30). CONCLUSION There may be two different phenotypes of AI with different clinical features: one developing AIA (having nasal polyp and/or rhinosinusitis, and smoking if food allergy/intolerance is present), and the other AI without asthma (having pet, and could smoke). Findings of this study should be confirmed by further investigations.

Abstract
Carbon monoxide (CO) is an important component of air pollution caused by traffic exhaust fumes. CO can cause chronic poisoning which shows its first symptoms as headaches, blurry vision, difficulty in concentration, and confusion. With the increasing number of vehicles in metropolitan areas of Turkey, the CO level has also increased in the city air as is the case in the capital city of Ankara, especially at certain locations. As far as the effects of CO on humans are concerned, traffic policemen are the population group under risk due to their inhalation of CO-rich air while on duty at the crowded cross-sections of the city. The traffic policemen on duty at these cross-sections are exposed to these high levels of CO for at least 6 h. This study was performed to investigate the traffic policemen (traffic organizers) who are exposed to high concentrations of CO at crowded cross-sections of Ankara City and to find out if chronic CO intoxication exits among this risk group. The CO levels in the ambient air at these cross-sections have also been compared to, and correlated with measurements of CO in the expired air of the target population. Additional factors like smoking, general health status, type of heating systems used at home, etc., have been taken into consideration by evaluating special questionnaires filled out by the policemen. A control group of clerk policemen, who were not engaged in street traffic activities was formed for comparative purposes.

Abstract
The prevalence of allergic diseases is reported to have increased worldwide. Two questionnaire surveys, five years apart, were conducted to evaluate the trend of prevalence rates and possible risk factors among primary school children in Ankara, Turkey. A previous survey in 1992 revealed the lifetime prevalences of asthma, wheezing, allergic rhinitis and atopic dermatitis were 17.4%, 23.3%, 28% and 6.1%, and the prevalences for the last 12 months were 8.3%, 11.9%, 15.4% and 4%, respectively. The survey was repeated with the same questionnaire in the same age group (6-13 years) of the same school in May 1997. The parents of 358 boys and 380 girls completed the questionnaire. The lifetime and last 12 months' prevalences of asthma, wheezing, rhinitis and atopic dermatitis were 16.8%, 22.5%, 18.7%, 6.5%, and 9.8%, 13.3%, 14.1%, 4.3%, respectively. There was a significant change only for the lifetime prevalence of rhinitis (p < 0.001). The rate of indoor smoking had declined from 73.9% to 64%, and pet ownership had risen from 7.9% to 22.9% (p < 0.001 for both). Atopic family history was the most prominent risk factor for all types of allergic disorders. Male gender was a significant risk factor for current asthma and wheezing [odds ratio (OR) = 1.80 and 1.59; 95% confidence intervals (CI) = 1.09-2.98 and 1.01-2.48, respectively], and passive smoking affected the occurrence of allergic rhinitis (OR = 1.84; CI = 1.13-3.00). The prevalence rates of allergic diseases among primary school children in Ankara stabilized during a 5-year period for all diseases other than allergic rhinitis. However, there are changing behavior patterns, i.e. indoor smoking and keeping pet animals, which that may have affected these rates.

Abstract
BACKGROUND Beekeeping has progressed recently to where bee sting exposure is an important public health problem in Turkey. OBJECTIVE To investigate the status of bee and wasp sting allergy in a region of Turkey. METHODS We conducted a questionnaire-based study of 786 subjects (cellulose paper factory personnel and family members older than 16 years of age) in Cay town of Afyon. Skin prick test with common aeroallergens and measurements of total IgE and specific IgE for bee and wasp venom were performed in 212 randomly selected subjects. RESULTS Cumulative lifetime sting rate was 94.5% (geometric mean: 6.1 times), and last year bee sting rate was 20.4% (geometric mean: 1.6 times). Subjects who had beehives had higher risk of bee sting (P < .05) in the last year, whereas there was no significant difference among the groups for the cumulative lifetime sting exposure. Severe and mild systemic reactions were noted in 2.2% and 5.3%, respectively. Emergency room visits were reported in 9.3%, and familial Hymenoptera allergy in 10.2%. Fatal potential of bee sting was known by 81%. There was no mortality related with Hymenoptera allergy in records of the last 5 years. In 24 subjects with multiple sting exposures, allergic reactions changed severity in the latter exposures, which became less severe in five and more severe in 19 subjects. Atopy rate detected by prick testing was 20.3%. Specific IgE levels were class 1 in 22, class 2 in 11, and class 3 in 2 subjects for bee; and class 1 in 24 and class 2 in 2 subjects for wasp. Nobody had received immunotherapy for venom allergy. None of the factors including atopy, sex, occupation, smoking and family history of bee sting was significantly related with severity of the systemic reaction (P > .05). CONCLUSIONS Bee and wasp stings are prevalent in Turkey. Severe systemic reactions complicating the sting are frequent (2.2%). Public awareness of potential fatality and treatment of the allergic reaction is not adequate.

Abstract
An epidemiological study was performed in the students of Hacettepe University from various parts of Turkey to find the prevalence of asthma and allergic diseases and search for geographical differences in Turkey. A questionnaire related with symptoms of asthma and allergic diseases was distributed to 4600 students and filled by 4331 students (1884 males, 43.5%-2447 females, 56.5%). Periodic prevalence of asthma or allergic disease during the last 12 months was 13.5%. The prevalence of awakening with chest tightness and/or feeling of retrosternal pressure in the last month was 2%. The current prevalences of the seasonal and perennial rhinoconjunctivitis, flexural eczema, food and drug intolerances, pollen and pet animal hypersensitivities were 6.4%, 1.6%, 0.8%, 4.5%, 3%, 5.2%, and 1% respectively. Drug, food, and pollen hypersensitivities were distinctively more common in the females, whereas wheezing was more common in males. Wheezing, wheezing associated shortness of breath, nocturnal asthma for the last 1 and 12 months were more common in the students from eastern region than those from western region. The highest asthmatic attack rate was reported in the eastern region. Seasonal rhinitis and pollen allergy were more prevalent in central region than northern region. No significant geographical difference was observed regarding the drug and pet hypersensitivities. Our study has shown the importance of asthma and allergic diseases as a public health problem. Explanation of the observed geographical differences aware for further studies.

Abstract
After several cases of malignant pleural mesothelioma (MPM) were detected in the village of Kureyşler in the Kütahya district of western Turkey, an epidemiological study was conducted. A questionnaire was completed by 124 villagers who were older than 20 years and standard posteroanterior chest X-rays were taken. The films were evaluated by three chest physicians. Samples of the white stucco that had been used by almost all villagers for indoor painting for many years were mineralogically examined. Chest X-rays showed that 23 (18%) had pleural plaques and calcifications compatible with asbestos exposure. Male sex and old age were associated with occurrence of pleural plaques. An analysis of white stucco samples revealed tremolite asbestos. In conclusion, tremolite fibers might be the cause of the high incidence of pleural plaques and MPM cases in the village of Kureyşler.

Abstract
We studied the mortality in three villages in the Cappadocian region of Central Anatolia, Karain, Tuzköy, and Sarihidir, which were exposed to fibrous zeolite (erionite), a known carcinogen more potent than the amphibole asbestos. Between 1970 and 1994, there were 305 deaths in Karain, and 177 (58%) were cancer related, including 150 (49.2%) malignant pleural mesothelioma, seven (2.3%) malignant peritoneal mesothelioma, and six (1%) gastroesophageal carcinoma. Four deaths (1.3%) from lung cancer included two nonsmoking females. There were three cases (1%) of leukemia and six of other malignancies (1.9%). Between 1980 and 1994, there were 519 deaths in Tuzköy (T) and Sarihidir (S) (T = 432, S = 87). Of these, 257 were cancer related, and included 120 cases of malignant pleural mesothelioma and 64 cases of malignant peritoneal mesothelioma. Intraabdominal carcinoma was noted in 29 patients and 14 patients had lung cancer (four of whom were nonsmoking women). There were five cases of gastroesophageal cancer, five deaths due to leukemia, and 16 cases of various malignancies. These mortality figures support the hypothesis that erionite fibers cause cancer other than mesothelioma and lung cancer. Mineralogic analyses of the tissues should be performed to demonstrate this relationship.
