RESUMO
Sucking patterns and early spontaneous movements have an important role in the determination of later developmental problems, but the relationship of the two together with long-term outcomes has not been investigated. The objectives of this study were to (i) examine the relationship between sucking patterns using the Neonatal Oral Motor Assessment Scale (NOMAS) and fidgety movements and other movement patterns using detailed General Movements Assessment (GMA), and (ii) investigate the relationship between these early assessment methods and developmental functioning outcomes at later ages. We analyzed the NOMAS from 34 weeks' postmenstrual age up to 10 weeks post-term and GMA between 9 and 20 weeks post-term age, and the Bayley Scales of Infant and Toddler Development-Third Edition (Bayley-III) was applied for the developmental functioning outcomes to 62 infants (61%, 62/102) between 12 and 42 months of age. Among 102 infants at-risk, 70 (69%) showed a normal sucking pattern, and 85 (83%) had fidgety movements. The median Motor Optimality Score-Revised (MOS-R), as determined by GMA, of all infants was 24. The NOMAS was related to the MOS-R and its subcategories (p < 0.05) in all infants at-risk. The NOMAS, MOS-R and its subcategories were also related to cognitive, language, and motor development at later ages according to Bayley-III (p < 0.05). Conclusion: This longitudinal study showed that the quality of sucking patterns, fidgety movements, and MOS-R were related to later developmental functioning, indicating that abnormal sucking patterns, aberrant fidgety movements, and lower MOS-R might predict developmental disorders. What is Known: ⢠Sucking patterns and early spontaneous movements in which central pattern generators play an important role are related. ⢠Sucking patterns and early spontaneous movements might be used separately to predict developmental outcomes. What is New: ⢠Sucking patterns and early spontaneous movements, when used together, were related to later developmental functioning, including cognitive, language, and motor development in at-risk infants. ⢠Predictive value of sucking patterns was lower for each developmental functioning outcome than early spontaneous movements.

INTRODUCTION: Based on animal studies, calcitonin gene-related peptide (CGRP) and pituitary adenylate cyclase-activating polypeptide (PACAP) are thought to play a role in neurobiological events such as neuropathic pain, neuroprotection, neurotransmission, neural plasticity, and neurotrophic effects. The aim of the study is to investigate whether there is a change in the blood level of CGRP and PACAP in patients with neuropathic pain and to look for clues about the utility of these peptides as pharmacological targets in the treatment of neuropathic pain in humans. METHODS: The study included 60 polyneuropathy patients with neuropathic pain, 30 polyneuropathy patients without neuropathic pain (NNP) and 29 healthy subjects as control group. Polyneuropathy patients with neuropathic pain were divided into two groups as diabetic (D-PNP) and non-diabetic polyneuropathy (ND-PNP) patients. Plasma CGRP and serum PACAP levels were measured from venous blood samples of the patients and healthy controls. RESULTS: The CGRP level was significantly higher in the D-PNP and ND-PNP groups compared to the control and NNP groups (P<0.05). PACAP levels were significantly higher in the D-PNP and ND-PNP groups compared to the control and NNP groups (P<0.05). There was no significant correlation between CGRP and PACAP levels and neuropathic pain scale (NPS). CONCLUSIONS: This study is the first to demonstrate elevated plasma CGRP and serum PACAP levels in polyneuropathy patients with neuropathic pain. The results of this study are important in terms of showing that both CGRP and PACAP can be new pharmacological targets in the treatment of neuropathic pain and polyneuropathy in humans.

OBJECTIVE: Familial Mediterranean fever (FMF), is an auto-inflammatory disease characterized by attacks of fever and serositis. Some scoring systems have been developed to evaluate the severity of the disease, however, predicting the severity of FMF is not possible with current knowledge. Our aim in this study was to evaluate the factors affecting disease severity in FMF. METHODS: This study included 150 FMF patients. The medical data of the patients were collected retrospectively and the International severity scoring system for Familial Mediterranean fever (ISSF) was used to evaluate disease severity. RESULTS: Patients were sorted into 3 groups based on the ISSF scores; ≤2=mild (Group 1; n: 61), 3-5=moderate (Group 2; n: 70), and ≥6=severe (Group 3; n: 19). Age at the onset of disease and age at diagnosis was younger in patients with severe disease (p: 0.009 and p: 0.031, respectively). Fever, peritonitis, and vasculitis were similar in all 3 groups. Pleuritis, erysipelas-like erythema (ELE), arthritis, myalgia, amyloidosis, and chronic kidney disease (CKD) were more common in Group 3. CONCLUSION: FMF patients with early onset and early diagnosis, having more frequent pleuritis, ELE, arthritis, and myalgia tended to manifest a more severe form of the disease. Close monitoring of such patients may prevent the development of amyloidosis and CKD and improve the long-term prognosis of the disease.
RESUMO
The Prechtl General Movement Assessment (GMA) has become a cornerstone assessment in early identification of cerebral palsy (CP), particularly during the fidgety movement period at 3-5 months of age. Additionally, assessment of motor repertoire, such as antigravity movements and postural patterns, which form the Motor Optimality Score (MOS), may provide insight into an infant's later motor function. This study aimed to identify early specific markers for ambulation, gross motor function (using the Gross Motor Function Classification System, GMFCS), topography (unilateral, bilateral), and type (spastic, dyskinetic, ataxic, and hypotonic) of CP in a large worldwide cohort of 468 infants. We found that 95% of children with CP did not have fidgety movements, with 100% having non-optimal MOS. GMFCS level was strongly correlated to MOS. An MOS > 14 was most likely associated with GMFCS outcomes I or II, whereas GMFCS outcomes IV or V were hardly ever associated with an MOS > 8. A number of different movement patterns were associated with more severe functional impairment (GMFCS III-V), including atypical arching and persistent cramped-synchronized movements. Asymmetrical segmental movements were strongly associated with unilateral CP. Circular arm movements were associated with dyskinetic CP. This study demonstrated that use of the MOS contributes to understanding later CP prognosis, including early markers for type and severity.
RESUMO
OBJECTIVE: To determine the effect of family-based intervention on motor function in preterm infants. METHODS: This study was designed as a randomized controlled trial between August 2015 and September 2016. Forty-two preterm infants were randomized and split equally between the family-based intervention group, composed of a physiotherapeutic and a familial component (8 males, 8 females; mean age 91+/-3.09 days), and the traditional early intervention group (8 females, 8 males, mean age: 91.06+/-2.4 days). Both groups received a treatment program based on a neurodevelopmental approach during 3- to 12-months-old. The groups were evaluated at corrected ages of the third, sixth, ninth, twelfth, and 24th months using the Bayley Scale of Infant and Toddler Development, Third Edition (Bayley-III). RESULTS: Within-group changes over time were statistically significant using multivariate tests of fine motor (Multivariate analysis of variance (MANOVA); F=1515.27, p less than 0.001) and gross motor (MANOVA; F=1950.59, p=0.001) development. However, there was no interaction between groups in fine (MANOVA; F=0.027, p=0.872) and gross motor development (MANOVA; F=0.022, p=0.883). CONCLUSION: The early intervention approaches might support fine and gross motor function development in preterm infants in the first year of life.

Wound healing requires cells that increase both collagen production as a result of inflammatory events and regeneration of epithelial tissue. The Plantago species of herbs have been used in traditional treatment of skin disorders and infectious diseases, and digestive, respiratory, reproductive and circulatory conditions. We investigated the efficacy of different concentrations of Plantago lanceolata L. extract (PLE) for wound healing owing to its anti-inflammatory, anti-bacterial, anti-fungal, anti-oxidant, anti-ulcerative, analgesic and immunomodulatory properties. We used 72 mice in four groups of 18. An excisional 1 cm wound was created in the skin on the back of the mice in all groups. An ointment containing 10% PLE was applied to the wound in group 1, an ointment containing 20% PLE was applied in group 2 and vaseline was applied in group 3. In group 4, no treatment was applied to the wound. On days 7, 14, and 21 of the experiment, six animals in each group were sacrificed after the wounds were photographed and specimens from the wound sites were examined. On day 14, epithelialization was more prominent in group 2, while vascularization and collagen deposition was more advanced in groups 1 and 2 compared to the other groups. Immunohistochemical examination revealed that TGF-ß1 expression was elevated on day 14 in all groups; however, this elevation was more limited in groups 1 and 2 than in groups 3 and 4. Although ANGPT-2 expression increased in groups 1 and 4 on day 14, it decreased significantly in groups 2 and 3. We found that different concentrations of PLE exhibited positive effects on wound healing. Application of 10% PLE ointment may be a useful strategy for wound healing.

BACKGROUND: This study was performed to evaluate the prevalence of all types and subtypes of dental anomalies among 6- to 40-year-old patients by using panoramic radiographs. MATERIALS AND METHODS: This cross-sectional study was conducted by analysing digital panoramic radiographs of 1200 patients admitted to our clinic in 2014. Dental anomalies were examined under 5 types and 16 subtypes. Dental ano-malies were divided into 5 types: (a) number (including hypodontia, oligodontia and hyperdontia); (b) size (including microdontia and macrodontia); (c) structure (including amelogenesis imperfecta, dentinogenesis imperfecta and dentin dys-plasia); (d) position (including transposition, ectopia, displacement, impaction and inversion); (e) shape (including fusion-gemination, dilaceration and taurodontism). RESULTS: The prevalence of dental anomalies diagnosed by panoramic radiographs was 39.2% (46% in men and 54% in women). Anomalies of position (60.8%) and shape (27.8%) were the most common types of abnormalities and anomalies of size (8.2%), structure (0.2%) and number (17%) were the least in both genders. Anomalies of impaction (45.5%), dilacerations (16.3%), hypodontia (13.8%) and taurodontism (11.2%) were the most common subtypes of dental anomalies. Taurodontism was more common in the age groups of 13-19 years. The age range of the most frequent of all other anomalies was 20-29. CONCLUSIONS: Anomalies of tooth position were the most common type of dental anomalies and structure anomalies were the least common in this Turkish po-pulation. The frequency and type of dental anomalies vary within and between populations, confirming the role of racial factors in the prevalence of dental ano-malies. Digital panoramic radiography is a very useful method for the detection of dental anomalies. (Folia Morphol 2018; 77, 2: 323-328).

It has been reported that renal stone formation increased in patients with ankylosing spondylitis (AS). However, its reason remains unclear. The aim of this study was to evaluate serially the possible risk factors for renal stone formation in AS patients. Two groups consisted of AS patients with renal stone (n = 30), AS patients without renal stone (n = 30), and 20 healthy controls (HC) were included to the study. Parathyroid hormone, calcium, magnesium, phosphorus and immunoglobulin A levels and 24 h urine were evaluated at baseline, and three times monthly. Serum calcium levels were higher in AS patients with urolithiasis than those without at baseline and third-month evaluation (baseline: 9.53 ± 0.3 vs 9.32 ± 0.3 mg/dl; p < 0.03; at third-month evaluation: 9.74 ± 0.2 vs 9.56 ± 0.3 mg/dl; p < 0.01). No significant differences were found between groups in terms of PTH and magnesium levels. In all evaluation times, although urinary calcium excretion was higher in AS patients with urolithiasis than in those without, it did not reach a statistical significance. IgA levels were significantly higher in renal stone sufferers than HC patients in all evaluation times.AS patients with urolithiasis also had high IgA levels compared with AS patients without renal stone at the second-month evaluation time (276 ± 102 vs 219 ± 104 mg/dl, p < 0.002). Increased levels of serum calcium and IgA levels as well as family history for urolithiasis may be an indicator of the development of urolithiasis in AS patients.

OBJECTIVE: This study aimed to investigate the frequency in which familial Mediterranean fever (FMF) coexists with other diseases and determine whether Mediterranean fever (MEFV) gene mutations are involved in such coexistence. MATERIAL AND METHODS: In total, 142 consecutive patients with FMF investigated for MEFV mutation were enrolled in this study [Female: 87; Male: 55, mean age 32±12 years (11-62)]. All the patients were questioned for the presence of concurrent disorders, and the medical records of these patients were revised retrospectively. A previous diagnosis of inflammatory disorder other than FMF was considered true if it met the relevant criteria. MEFV mutations were divided into 2 groups, namely M694V and its subgroup (homozygous or heterozygous) (Group I) and others (Group II). Compound heterozygosity for M694V mutation was included in Group II to form a homogeneous group for Group I. Group I and Group II were compared according to phenotypical features. The presence of MEFV mutation was investigated in exons 2, 3, 5, and 10 by the multiplex-PCR reverse hybridization method. RESULTS: Concomitant disorders were found in 17 of 73 patients with FMF (23%) in Group I and 5 of 56 patients (8.9%) in Group II (p=0.04). Concomitant disorders in Group I were as follows: 7 cases of amyloidosis, 2 cases of Behcet's disease (BD), 4 cases of ankylosing spondylitis (AS), 1 case of antiphospholipid syndrome, 1 case of Henoch-Schonlein purpura (HSP), 1 case of combination of psoriatic arthritis, HSP, and membranoproliferative glomerulonephritis, and 1 case of AS and amyloidosis. In Group II, the following disorders were found: 1 case of amyloidosis, 1 case of BD, 1 case of AS, 1 case of ulcerative colitis, and 1 case of vitiligo. CONCLUSION: The presence of M694V mutation may predispose patients with FMF to developing other inflammatory disorders.
RESUMO
OBJECTIVES: Behçet's disease (BD) is a chronic, multisystemic disorder characterised by recurrent oral aphtous ulcers, genital ulcers and ocular inflammation. Vasculitis and thrombotic events are the most important causes of mortality. Vena cava thrombosis, pulmonary artery aneurysms, Budd-Chiari syndrome, peripheral artery aneurysms, dural sinus thrombosis and abdominal aorta aneurysms are the other less common vascular manifestations of BD. Cardiac involvement in BD is a rare and life-threatening complication. The aim of this study was to assess the clinical characteristics and outcome of patients with BD who have intracardiac thrombus. METHODS: The hospital files of BD patients followed by rheumatology clinics of four medical centres (Ankara University, Ege University, Hacettepe University and Eskisehir Osmangazi University Hospitals) were retrospectively evaluated. Data included patients' demographic and clinical features, laboratory findings and outcome. All patients fulfilled three or more of the International Study Group Criteria for BD. RESULTS: Twenty-two patients with intracardiac thrombus were evaluated. The mean age of patients with intracardiac thrombosis was 29.1 yrs (22-44) and there was a male predominance with a ratio of 20:2. Cardiac involvement was the first clinical manifestation of BD in 9 of the 22 patients. Initial symptoms of the patients were fever (n=18, 81%), dyspnea (n=9, 40%) chest pain (n=9, 40%) and haemoptysis (n=7, 31.8%). Sixteen patients (72%) had pulmonary arteritis and 10 (45%) patients had venous system lesions included deep vein, inferior vena cava and hepatic vein. Intra-cardiac thrombus were found only in the right cavities in 17 patients (77%), only in the left cavities in 2 patients (9%), and in both left and right cavities of the heart in 3 patients (13.6%). Once the cardiac lesion was diagnosed as a complication of BD, high dose (1mg/kg/d) prednisone (n=22, 100%) plus cyclophosphamide (n=18, 81%) or azathioprine (n=3, 13.6%) and warfarin (n=8, 36.3% (after the elimination of pulmonary aneurysm) therapy for anticoagulation was initiated. Four patients (18%) had high dose prednisone plus cyclophosphamide plus interferon-α (IFN-α) combination treatment and two patients (n=2, 9%) had high dose prednisone plus cyclophosphamide or plus azathioprine combination treatment. After treatment, the intra-cardiac thrombus disappeared in 13 cases and the size of the thrombus reduced in 7 cases. One patient died because of recurrent intra-cardiac thrombus and massive pulmonary arteritis in the emergency department. CONCLUSIONS: Intracardiac thrombus in BD is more common in young men. The right side of the heart is usually involved and cardiac involvement is often accompanied by pulmonary artery occlusion possibly due to pulmonary arteritis. Early and aggressive immunosuppressive and/or anticoagulation therapy are life-saving.

The disorder comprising Macrocephaly, Alopecia, Cutis laxa, and Scoliosis has been designated MACS syndrome. It is a rare condition, inherited in an autosomal recessive pattern. Three families from different ethnic origins have so far been reported and were all linked to homozygous mutations in RIN2, a gene encoding the Ras and Rab interactor 2 protein involved in cell trafficking. We describe herein the fourth family with MACS syndrome in two siblings carrying a novel homozygous mutation, c.1878_1879insC in exon 8 of the RIN2 gene, which predicts p.Ile627Hisfs*7. We also report on additional findings not previously described in MACS syndrome, including bronchiectasis and hypergonadotropic hypogonadism. Finally, our overall data support the argument that RIN2 syndrome is a more appropriate name for the disorder.

OBJECTIVE: The aim of this study is to determine the incidence of isoniazid (INH)-related hepatotoxicity in patients with rheumatologic diseases receiving tumor necrosis factor-α (TNF-α) antagonists along with a disease-modifying antirheumatic drug (DMARD). MATERIAL AND METHODS: We have retrospectively evaluated 87 patients receiving anti-TNFα agents who were followed up between June 2005 and February 2010 at our rheumatology department. Sixty-one of 87 patients have received INH prophylaxis for 9 months for latent tuberculosis infection. RESULTS: A total of 61 (70.1%) of 87 patients used INH prophylaxis (Group I), while the remaining 26 (29.9%) (Group II) had not; 53 patients had used any DMARD in Group I, while 21 patients had used in Group II. No significant differences were found among Group I and II with respect to clinical features. When two groups were compared, in Group I, elevations of liver enzymes were detected in five patients (8.1%) who had normal baseline values. Among these patients, hepatotoxicity developed in two patients. Hepatotoxicity developed one patient in Group II (p=0.85). CONCLUSION: INH chemoprophylaxis was well tolerated in patients using anti-TNF-α agent and a DMARD. It seems not to be a strong risk factor for hepatotoxicity. However, comorbidities and other drugs used may be additional factors in the elevation of transaminases.
RESUMO
Behcet's disease (BD) is a multisystemic disorder characterised by recurrent oral and genital ulcers. Vasculitis and thrombotic events are the most important causes of mortality. Thrombosis is the major clinical finding in patients with BD, but the cause of the thrombosis is still unclear. Thromboelastography is an alternative method to evaluate almost all steps of the hemostatic system. Today, the modified rotation thromboelastogram (ROTEM) is a newer coagulation test and a more powerful technique. Our aim in this study was to investigate whether hemostatic mechanisms play a role in the development of thrombosis in BD patients by using ROTEM. Thirty BD patients, 20 ankylosing spondylitis patients, and 14 healthy controls who are not taking anti-aggregant or anti-coagulant therapy were included in the study. Whole blood count, protrombin time, activated protrombin time, fibrinogen, D-dimer levels, and ROTEM parameters (clotting time, clot formation time (CFT), and maximum clot formation(MCF)) were determined by INTEM and EXTEM analysis. Of the 30 patients with BD, 19 were women and 11 were men, and mean age was 40.6 ± 11.2. Two of the BD patients had vascular involvement, but none of them were in active phase of the disease during the study. In INTEM assay, MCF (p < 0,001) value was significantly increased, and CFT (p>0.05) value was decreased in BD patients compared with the control group. In the EXTEM assay, there was a similar significant increase in MCF (p=0.002) value and a decrease in CFT (p=0.002) value in BD patients compared with the control group. The results of our study indicated that primary hemostatic mechanisms which can be detected by ROTEM may play a role in the development of thrombosis in patients with BD.

Antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitides are rare, but they can be triggered by chemicals, infections and drugs; among them, antithyroid drugs are common. Autoimmune disorders, such as vasculitis, are unusual, but serious complications of antithyroid therapy. Both propylthiouracil (PTU) and methimazole may induce ANCA-associated vasculitis. PTU-induced vasculitides may have different organ involvement patterns. Herein, we report four cases with ANCA-associated vasculitis with different clinical manifestations.

BACKGROUND: Doxorubicin is an antineoplastic agent that causes skin necrosis when extravasated. Various agents have been tried to reduce tissue damage owing to extravasation. Erythropoietin (EPO) is an obligatory growth factor for red blood cells and has beneficial effects on wound healing. OBJECTIVE: The aim of this study was to test the hypothesis that local EPO injection can prevent and improve healing of necrosis at the doxorubicin injection site in rats. METHODS: We used 31 female Sprague-Dawley rats. The dorsal area of each rat was shaved, and 2 mg of doxorubicin in 0.5 mL saline was injected intradermally. The rats were then divided into 3 groups: control; control with intradermal injection of saline; and treatment, which received an intradermal injection of EPO. EPO in saline was injected into 4 quadrants of the same site where doxorubicin was injected 1 hour before. The rats were monitored and the area of each ulcer was measured. Skin biopsies were excised at the end of 4 weeks using anesthetic pentobarbital. Inflammation, edema, epithelization, neovascularization, necrosis, fibroblast proliferation, and collagen synthesis were evaluated and compared between groups. RESULTS: The average areas of the lesions were significantly smaller in the EPO-injected rats (P = 0.03). The histopathologic evaluation revealed that the scores for epithelization, neovascularization, fibroblast proliferation, and collagen synthesis were higher (P < 0.001, P < 0.001, P = 0.002, and P = 0.04, respectively) and the score for necrosis was lower (P < 0.001) in the EPO-injected group than in both the saline-injected and control groups. CONCLUSIONS: In this study using female Sprague-Dawley rats, EPO treatment improved the healing of skin necrosis caused by doxorubicin injection. This finding may lead to a new therapeutic approach for the management of skin necrosis caused by doxorubicin extravasation.
RESUMO
PURPOSE: A prospective phase II trial was conducted by the Institute of Oncology, Istanbul University in December 1994 on patients with locally-advanced non-small cell lung cancer to assess acute toxicity and the feasibility of a combination of radiosensitizer and accelerated radiotherapy with concomitant boost. MATERIALS AND METHODS: Patients were irradiated using 'large' fields (primary tumour and locoregional lymph nodes) with 1.8 Gy per fraction, five fractions a week. Reduced 'boost' fields (primary and involved nodes only) were also irradiated twice-weekly 1.8 Gy per fraction in ten fractions concomitantly 6 h after the administration of large field. Total radiation dose was 63 Gy in 5 weeks (45 Gy 'large' fields and 18 Gy 'boost'). The maximum allowed dose to the spinal cord was 3750 cGy. Cisplatinum, 6 mg/m2 was given daily just before 'large' field irradiation. RESULTS: As of January 1997, 15 patients were evaluated (median follow-up of 12.5 months with a range of 5.5-23 months). The overall acute toxicity rate was 38% and Grade 3 acute toxicity was 8%. Grade 4 or greater acute toxicities were not observed. The overall rate of cisplatinum-induced nausea and vomiting was 80% (severe in 60%), but all were easily treated with antiemetics. Complete response rate (clinical and radiological) was 40% and an overall response rate was 73%. Median survival was 16 months and progression-free survival was 5.5 months (range of 2.5-21 months). CONCLUSIONS: Toxicity was well tolerated and no treatment-related death occurred with this combined treatment regimen. Although it appears that better local control rates can be achieved, additional phase II/III studies are needed.

Little is known about cultural differences in psychological adjustment and perception of illness (PI) during medical procedures in general and radiotherapy in particular. This study compares a Turkish (TP) and a French speaking Belgian (BP) population. A group of 296 consecutive patients attending the radiotherapy clinic of Institut Jules Bordet, Brussels, (n = 172) and Oncology Institute, Capa-Istanbul, (n = 124) were interviewed and assessed by a symptom checklist, the SCL-90-R, at the beginning and at the end of the radiotherapy. PI, derived from a semi-structured interview, was assessed at the beginning of radiotherapy by a five-point observer-rating scale derived from the Omega Vulnerability Rating Scale. Differences in SCL-90-R scores, taking into account country, age, gender, level of education and PI as potential explanatory variables, have been tested by a multivariate analysis of variance with a design of repeated measures using the SCL-90-R scores as dependent variables. Mainly a time effect and a country effect have been found. Some interactions between both effects have also been found. Globally, all the SCL-90-R scores decrease between the beginning and the end of the radiotherapy. The effect of country is noticeable for most of the SCL-90-R components, with higher scores in the BP, except for the positive symptom total score where the TP showed higher scores. The interaction between country and time is not significant, the scores of both the BP and TP decreasing over time, except for somatization scores (P < 0.001) where the scores of the BP were stable over time while the scores of the TP decreased considerably, and for paranoid ideation scores (P = 0.001) where the scores of the BP decreased while the scores of the TP increased. Results showed a higher rate of correct perception in the BP compared to the TP (P = 0.0001). A PI effect has been found for somatization (P = 0.02), anxiety (P = 0.01) and Global Severity Index scores (P = 0.05), with higher mean scores for the "correct perception" category. No interaction with time was found. A significant interaction effect between country and PI has been found for anxiety scores with higher scores in the correct perception category in the BP and in the "denial of implications" category in the TP (P < 0.001). Results highlight cultural differences in psychological adjustment and/or in the responses to self-report questionnaires: greater weight was given to items by the BP, more numerous items were scored by the TP, and greater weight was given to the somatization subscale compared to the psychological subscales by the TP. This study suggests that psychosocial distress is expressed differently in Belgium and Turkey, where patients express mostly somatic complaints. Finally PI, a culture-dependent factor, appears to influence psychological adjustment very differently, a correct perception of illness leading to more anxiety in the BP compared to the TP.
