Effectiveness of multimedia-assisted training on inhaler usage technique, which is the optimum technique?

OBJECTIVE

In this study, we aimed to investigate the most appropriate education method for patients to use their inhaler devices with the proper technique.

PATIENTS AND METHODS

The study had a cross-sectional, multicenter design. 525 consecutive patients who had never used an inhaler therapy before were included in the study. Seven different types of inhalers were evaluated. 75 patients were included for each device type. For each device type, 25 patients were trained by their own physicians who personally demonstrated the use of the device [verbal education with physical demonstration (VEWPD)], 25 were given multimedia-assisted training (MAT), and 25 received both types of training together (first VEWPD followed by MAT). After the patients were trained, inhaler medications were used under the supervision of a physician. Correct use of the inhaler devices and perceptions of convenience were scored.

RESULTS

For Ellipta inhaler device and Levered Diskus inhaler device, the proportion of patients using their devices properly was significantly higher in patients who were instructed with both of the methods together compared to other education groups (p = 0.011, p = 0.015). The effects of different types of training on learning in Sanohaler, Diskus inhaler, and Pressurized metered dose inhaler devices were the same.

CONCLUSIONS

We could not come to a conclusion that multimedia training was more beneficial than other training. As an unexpected result, in almost all of the devices, patients who received multimedia training in combination with verbal training did not develop better learning despite being shown the use of the device twice (except Ellipta inhaler, and Levered Diskus inhaler device).

Comprehensive biomarker analysis of patients with idiopathic pulmonary fibrosis and interstitial lung disease with healthy individuals

OBJECTIVE

Interstitial lung diseases (ILDs) are a group of diffuse parenchymal lung disorders that can be idiopathic [idiopathic pulmonary fibrosis (IPF)] or associated with other diseases and are characterized by varying degrees of inflammation and fibrosis with poor prognosis. Several indicators are essential in diagnosing these individuals and differentiating between IPF and ILD.

PATIENTS AND METHODS

The study involved 44 IPF patients, 22 ILD (non-IPF) patients, and 24 healthy people. We aimed to compare ILD (non-IPF) and IPF patient groups with each other and with healthy people in terms of interleukin (IL)-1, tumor necrosis factor-alpha (TNF-α), matrix metalloproteinase (MMP)-1, MMP-7, galectin (Gal)-3, IL-6, Krebs von den Lungen-6 (KL-6), total antioxidant status (TAS), total oxidant status (TOS), pyruvate kinase (PK), complete blood count (CBC), ferritin, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) features. Furthermore, it was intended to assess the patient groups in terms of visual semi-quantitative score (VSQS) (IPF alone), respiratory function tests (RFT), and 6-minute walk test (6MWT), also potential correlations between these tests and the previously indicated parameters.

RESULTS

MMP-1, MMP-7, Gal-3, IL-6, KL-6, forced vital capacity (FVC), % FVC, forced expiratory volume in 1 second (FEV1), % FEV1, TAS, TOS, and PK values significantly elevated in IPF and ILD. Weight, IL-1, MMP-1, MMP-7, Gal-3, IL-6, KL-6, % FVC, FEV1, % FEV1, eosinophil count, and % red blood cell distribution width (RDW) values differed between IPF and ILD. VSQS, 6MWT, and PK were substantially linked with MMP-1, MMP-7, Gal-3, IL-6, and KL-6 in IPF.

CONCLUSIONS

The factors investigated can be helpful in the diagnosis and distinction of IPF and ILD. In addition to focusing on the inflammatory environment in IPF and ILD patients, oxidant and antioxidant interactions must be studied.

POS0975 COMPARISON OF CLINICAL AND DEMOGRAPHIC FINDINGS OF PATIENTS DIAGNOSED AS WITH FULL SPINAL FUSION AND WITHOUT ANY SPINE DAMAGE

Background

Erosions and sclerosis are early manifestations of radiographic progression, which can form syndesmophytes that bridge between the vertebrae and eventually lead to spinal fusion or the characteristic bamboo spine appearance in some patients.Bridging syndesmophytes in the spinal column plays a key role in the progression of AS.1 The development of ankylosis in the axial skeleton is considered to be the most important long-term outcome parameter for axial pondyloarthritis (axSpA).2

Objectives

In this study, we aimed to evaluate patients with ankylosing spondylitis (AS) diagnosed with grade 4 sacroiliitis followed in our rheumatology clinic, without spinal column involvement and with complete spinal ankylosis (bamboo vertebra), together with their clinical, demographic and laboratory findings.

Methods

A total of 202 patients with unilateral/bilateral grade 4 sacroiliitis, who were registered in the Dokuz Eylul University Hospital data system, diagnosed with AS according to the modified New York criteria, were included in the study. Cervical, dorsal and lumbar radiographs of all patients were evaluated for structural damage, in addition to lateral and anteroposterior aspects, as well as posterior and facet joint involvement. In the study, all radiographs were evaluated twice at separate times.

Results

It was found that 19 (9.5%) patients had no involvement of the spinal column and 19 (9.5%) had spinal fusion appearance. It was determined that patients with spinal fusion were older (p<0.001) and the frequency of male gender was higher (p=0.042) than patients without any spinal involvement.(Table 1) In multivariate analysis; ≥45 years old [OR: 10.5, CI: 95%, 2.8-39.2; (p<0.001)] and male patients [OR: 10.5, CI: 95%, 1.14-96.56; (p=0.042)] was found to have an increased risk for the development of spinal fusion. TNFi retention rates (78.9% vs. 52.6%), TNF switch rates (53.3% vs. 45.5%) and TNF type distributions were similar in both groups (p>0.05).There was no significant difference between the patients with complete spinal fusion and no spinal involvement in terms of right and left hip BASRI scores (p>0.05).

Conclusion

In our study, we reached four important clinical results: (1) Spinal fusion was observed in 9.5% of the patients with bilateral Grade 4 sacroiliitis diagnosed with AS, 9.5% had no spinal involvement and 81% had varying degrees of spinal injury. (2) Anti-TNF treatment responses were similar in patients with spinal fusion and no spinal involvement. (3) Except for being >45 years old and having a male gender, no other factor was found to predict the development of spinal fusion. (4) There was no difference in the degree of hip involvement between patients with complete spinal fusion and no spinal involvement.

Quantitative OCT angiography of the retina and choroid in non-ocular sarcoidosis

OBJECTIVE

The aim of the study was to evaluate retinal and choroidal microvascular morphological changes in non-ocular sarcoidosis (NOS) patients using optical coherence tomography angiography (OCTA) and compare the results to age- and gender-matched healthy individuals.

PATIENTS AND METHODS

This study included 37 NOS patients (group 1, 37 right eyes) referred to the Ophthalmology Department between 2019 and 2021, as well as 31 healthy individuals (group 2, 31 right eyes). Non-ocular sarcoidosis was defined as sarcoidosis confirmed by a positive lung X-ray and biopsy without ocular manifestation. All participants underwent a comprehensive ophthalmic examination. The SPECTRALIS® OCT was used for both fundus photography and macular analysis. All OCTA procedures were performed in the Angio Retina mode (6.0x6.0 mm) to assess retinal and choroidal microvascular morphology.

RESULTS

Groups 1 and 2 had mean ages of 46.41±12.52 and 47.55±13.81 years, respectively (p=0.482). Group 1 had significantly increased superficial capillary plexus (SCP) and deep capillary plexus (DCP) vessel densities (VDs) in whole (p=0.059, 0.016), parafoveal (p=0.051, 0.015), and perifoveal (p=0.060, 0.010) regions relative to group 2. Group 1 was also associated with increased foveal avascular zone (FAZ) area (p=0.196), FAZ circumference (p=0.262), and foveal VD in 300 μm wide regions surrounding FAZ (p=0.003) relative to group 2. The outer retinal (p=0.712) and choriocapillaris (p=0.684) flows did not differ significantly between the two groups.

CONCLUSIONS

Quantitative OCTA analysis revealed a higher tendency for retinal and choroidal microvascular morphological changes in NOS patients, demonstrating the potential of this novel, non-invasive imaging technology, which may provide sensitive and reliable results without using contrast materials.

Risk factors for diabetic foot ulcers in metreleptin naïve patients with lipodystrophy

AIM

Patients with lipodystrophy are at high risk for chronic complications of diabetes. Recently, we have reported 18 diabetic foot ulcer episodes in 9 subjects with lipodystrophy. This current study aims to determine risk factors associated with foot ulcer development in this rare disease population.

METHODS

Ninety metreleptin naïve patients with diabetes registered in our national lipodystrophy database were included in this observational retrospective cohort study (9 with and 81 without foot ulcers).

RESULTS

Patients with lipodystrophy developing foot ulcers had longer diabetes duration (p = 0.007), longer time since lipodystrophy diagnosis (p = 0.008), and higher HbA1c levels (p = 0.041). Insulin use was more prevalent (p = 0.003). The time from diagnosis of diabetes to first foot ulcer was shorter for patients with generalized lipodystrophy compared to partial lipodystrophy (p = 0.036). Retinopathy (p < 0.001), neuropathy (p < 0.001), peripheral artery disease (p = 0.001), and kidney failure (p = 0.003) were more commonly detected in patients with foot ulcers. Patients with foot ulcers tended to have lower leptin levels (p = 0.052). Multiple logistic regression estimated significant associations between foot ulcers and generalized lipodystrophy (OR: 40.81, 95% CI: 3.31-503.93, p = 0.004), long-term diabetes (≥ 15 years; OR: 27.07, 95% CI: 2.97-246.39, p = 0.003), and decreased eGFR (OR: 13.35, 95% CI: 1.96-90.67, p = 0.008).

CONCLUSIONS

Our study identified several clinical factors associated with foot ulceration among patients with lipodystrophy and diabetes. Preventive measures and effective treatment of metabolic consequences of lipodystrophy are essential to prevent the occurrence of foot ulcers in these high-risk individuals.

Toxic Effects of Tetrabromobisphenol A: Focus on Endocrine Disruption

Tetrabromobisphenol A (TBBPA) is a brominated flame retardant that is used in a variety of consumer products such as electronic equipment, fire extinguishers, furniture, plastics, textiles, and kitchen hoods. Most studies show that the TBBPA production process and TBBPA in industrial and urban sewage waste result in extensive human exposure and environmental contamination. TBBPA can accumulate in organisms, particularly aquatic life, and is classified as a group 2A carcinogen (likely carcinogenic to humans) by the International Agency for Research on Cancer. This compound produces low acute toxicity, but chronic exposure may produce serious consequences. In this review, we focus on TBBPA toxicity by discussing results of various studies that were published in the last two decades. Studies show that TBBPA acts as an endocrine disruptor, causing neurobehavioral and immunotoxic effects, oxidative stress, and apoptosis. Although several experiments were performed in vitro and in vivo, human data are lacking, and thus, chronic toxic effects of TBBPA on humans are not well known, particularly in sensitive populations including pregnant women, newborns, children, and the elderly. Epidemiological studies that comprehensively assess TBBPA levels in biological fluids of different populations and in different pathological conditions are needed. Research on the impact of TBBPA, particularly regarding endocrine disorders and cancer, must also be performed.

POS0750 THE CHARACTERISTICS OF SYSTEMIC LUPUS ERYTHEMATOSUS WHO HAVE CONSTITUTIONAL SYMPTOMS AND LYMPHADENOPATHY

Background:

Systemic lupus erythematosus (SLE) is the prototype of systemic autoimmune diseases. It may affect any organ system and may present with a variety of clinical symptoms. Lymphadenopathy (LAP) is a nonspecific finding of SLE and often associated to the active disease state. LAP associated SLE pose a significant diagnostic challenge especially in the presence of constitutional symptoms.

Objectives:

In this retrospective cohort study, we evaluated the clinical and imaging characteristics of SLE patients who presented with LAP and constitutional symptoms.

Methods:

SLE Patients with lymphadenopathy who had constitutional symptoms were reviewed retrospectively. The characteristics of the patients such as age, sex, disease duration, clinical features, and laboratory tests including autoantibodies against ANA, dsDNA and ENA were recorded. Imaging findings such as positron emission tomography–computed tomography (PET/CT), thoracal or abdominal CT or diagnostic lymph node biopsy were identified.

Results:

There were 28 patients in this study. The mean age at the time of LAP was 38.9±15.2 years, 22 (78.6%) were female. All patients were fulfilling SLICC 2012 classification criteria for SLE. LAP was the presenting feature of SLE in 15 (53.6%) patients. The most common clinical features associated with LAP were arthritis (42.8%), fever (35.7%), acute lupus rash (32.1%) and serositis (28.5%). There were 11 (39.2%) who had significant proteinuria and 4 (14.3%) had class III or IV renal histology. Anti-phospholipid antibodies were present in nearly one-third of the patients and 12 of them had venous or arterial thrombosis or pregnancy co-morbidity. Cervical LAP was present in 57.1%, axillary LAP in 82.1% and inguinal in 36%. On CT, the prevalence of thoracal and abdominal LAP and hepatomegaly and splenomegaly were 61.5%, 37,5%, 40% and 16% respectively. The pericardial and pleural effusion and intra-abdominal free fluid were 19.2%, 30.8% and 10.2% respectively. There were 19 (67.8%) patients who underwent PET/CT imaging and all were reported as reactive LAP. In terms of SUV max 7 (36.8%) of them had a threshold ≥2.5. 17 (60.7%) patients required lymph node biopsy; 2 did not include lymphoid tissue, 4 (30.7%) with atypical lymphoid hyperplasia suggestive of viral infection and remaining were reactive lymphoid hyperplasia. Autoantibody testing showed that anti-dsDNA was positive in 66.7% and the most common anti-ENAs were anti-nucleosome (35.7%) and anti-Sm-RNP (35.7%) followed by anti-SSA (25%), anti-ribosomal P (17.9%) and anti-histone (14%). The clinical and laboratory features of the clinical and laboratory features of the group is summarized in Table 1.

Conclusion:

We showed that SLE patients who had constitutional findings and LAP could be the presenting feature and may confer a significant diagnostic challenge in which the patients might require invasive procedures and advanced imaging modalities. PET/CT revealed reactive changes in lymph nodes in all patients but lymph node biopsy revealed atypical changes in some patients suggestive of viral infections. On the other hand, LAP patients with constitutional symptoms represents a severe phonotype of the SLE as there were significant renal and thrombotic disease.

Neuroendocrine disruption by bisphenol A and/or di(2-ethylhexyl) phthalate after prenatal, early postnatal and lactational exposure

Bisphenol A (BPA) and di(2-ethylhexyl)phthalate (DEHP) are abundant endocrine disrupting chemicals (EDCs). In recent years, studies showed that EDCs may lead to neurodevelopmental diseases. The effects of prenatal exposure to these chemicals may have serious consequences. Moreover, exposure to EDCs as a mixture may have different effects than individual exposures. The present study aimed to determine the toxicity of BPA and/or DEHP on central nervous system (CNS) and neuroendocrine system in prenatal and lactational period in Sprague-Dawley rats. Pregnant rats were randomly divided into four groups: control (received vehicle); BPA group (received BPA at 50 mg/kg/day); DEHP group (received DEHP at 30 mg/kg/day); and combined exposure group (received both BPA at 50 mg/kg/day and DEHP at 30 mg/kg/day) during pregnancy and lactation by oral gavage. At the end of lactation, male offspring (n = 6) were randomly grouped. The alterations in the brain histopathology, neurotransmitter levels and enzyme activities in the cerebrum region, oxidative stress markers, and apoptotic effects in the hippocampus region were determined at adulthood. The results showed that exposure to EDCs at early stages of life caused significant changes in lipid peroxidation, total GSH and neurotransmitter levels, and activities of neurotransmitter-related enzymes. Moreover, BPA and/or DEHP led to apoptosis and histopathologic alterations in the hippocampus. Therefore, we can suggest that changes in oxidant/antioxidant status, as well as in neurotransmitters and related enzymes, can be considered as the underlying neurotoxicity mechanisms of BPA and DEHP. However, more mechanistic studies are needed.

Histopathologic, apoptotic and autophagic, effects of prenatal bisphenol A and/or di(2-ethylhexyl) phthalate exposure on prepubertal rat testis

Bisphenol A (BPA) and di(2-ethylhexyl) phthalate (DEHP) are endocrine-disrupting chemicals (EDCs) used in a wide variety of industrial products as plasticizers. Exposure to EDCs, particularly in mixtures, in prenatal and early postnatal periods may lead to unwanted effects and can cause both developmental and reproductive problems. In this study, we aimed to determine the individual and combined effects of prenatal and lactational exposure to BPA and/or DEHP on testicular histology, apoptosis, and autophagic proteins. Pregnant Sprague-Dawley rats (n = 3) were divided into four groups (control, BPA (50 mg/kg/day), DEHP (30 mg/kg/day), and BPA (50 mg/kg/day) + DEHP (30 mg/kg/day)) and dosed by oral gavage during pregnancy and lactation. The male offspring (n = 6) from each group were chosen randomly, and their testicular examinations were performed on the twelfth week. The results showed that fetal and neonatal exposure to BPA and DEHP could lead to significant testicular histopathological alterations and cause increases in apoptosis markers (as evidenced by increases in caspase 3 and caspase 8 levels; increased TUNEL-positive spermatogonia and TUNEL-positive testicular apoptotic cells) and autophagic proteins (as evidenced by increased LC3 and Beclin levels and decreased p62 levels) in testicular tissue. We can suggest that EDCs cause more dramatic changes in both testicular structure and cell death when there is combined exposure.

Oxidative Stress Parameters, Selenium Levels, DNA Damage, and Phthalate Levels in Plastic Workers

Di(2-ethylhexyl)phthalate (DEHP) is the most widely used phthalate. DEHP is highly used in PVC floorings and PVC windows and carpeting. The objective of this study was to determine sex hormone levels, oxidative stress parameters, selenium levels, DNA damage, and phthalate levels in plastics workers (n = 24, age = 20-58 years) working in the production of rubber mechanical goods and exposed to DEHP in workplace. The control group (n = 29, age = 25-54, all male) was selected from age-matched healthy adults. Antioxidant parameters and DNA damage were determined by spectrophotometry. Selenium levels were determined by atomic absorption spectroscopy. Plasma hormone levels were measured by chemiluminescence microparticle immunoassay. Plasma phthalate levels were determined by high-pressure liquid chromatography. Plastic workers had lower serum testosterone and free T4 levels and higher follicle-stimulating hormone levels vs. controls. Liver enzyme activities were markedly higher in workers vs. controls. There were also increases in plasma glutathione peroxidase levels and marked decreases in plasma selenium and erythrocyte total glutathione levels in plastics workers (P < 0.05 vs. control). Plasma 8-hydroxy-2'-deoxyguanosine levels were 14-fold higher in plastics workers than in controls. Plasma DEHP and mono(2-ethylhexyl)phthalate were also markedly higher in workers vs. controls. The results of this study show that occupational exposure to DEHP may lead to disturbances in sex hormones, increased liver problems, higher oxidative stress and DNA damage levels, and lower trace element concentrations in workers. More comprehensive and mechanistic studies with higher numbers of subjects are needed to show the unwanted effects of occupational exposure to DEHP.

Uteroplacental Doppler flow and pregnancy outcome in women with tetralogy of Fallot

OBJECTIVE

Pregnancy in women with surgically corrected tetralogy of Fallot (ToF) is associated with cardiac, obstetric and neonatal complications. We compared uteroplacental Doppler flow (UDF) measurements and pregnancy outcome in women with ToF and in healthy women and aimed to assess whether a relationship exists between cardiac function and UDF in women with ToF.

METHODS

We evaluated prospectively pregnant women with ToF and healthy pregnant women from the ZAHARA studies. Clinical evaluation, standardized echocardiography and UDF measurements were performed at 20 and 32 weeks' gestation.

RESULTS

We included 62 women with ToF and 69 healthy controls. Cardiac complications, mostly arrhythmia, occurred in 8.1% of women with ToF. There was a higher incidence of small-for-gestational age (21.0% vs 4.4%, P = 0.004) and low birth weight (16.1% vs 2.9%, P = 0.009) in the group of women with ToF than in healthy controls. In women with ToF, early diastolic notching of uterine artery waveform at 20 and 32 weeks occurred more frequently (9.8% vs 1.5%, P = 0.034 and 7.0% vs 0%, P = 0.025, respectively) and the umbilical artery pulsatility index at 32 weeks was higher (1.02 ± 0.20 vs 0.94 ± 0.17, P = 0.015) than in healthy controls. Right ventricular function parameters prepregnancy and at 20 weeks' gestation were significantly associated with abnormal UDF. UDF parameters were associated with adverse neonatal outcome.

CONCLUSION

The majority of women with surgically corrected ToF tolerate pregnancy well. However, UDF indices are more frequently abnormal in these women, suggesting impaired placentation. The association of impaired right ventricular function parameters with abnormal UDF suggests that cardiac dysfunction contributes to defective placentation or placental perfusion mismatch and may explain the increased incidence of obstetric and neonatal complications.

Copper, zinc and iron levels in premature infants following red blood cell transfusion

This study aimed to investigate effect of erythrocyte suspension (ES) transfusion on Cu, Zn, and Fe levels. It was conducted on 53 premature infants who were admitted to Hacettepe Hospital and received EST for first time. Blood samples were drawn before and 96h after ES transfusion to determine Cu, Zn, and Fe levels in plasma and/or erythrocytes. The mean plasma Cu levels were 99±3μg/dl and 113±3μg/dl; Zn levels were 105±2μg/dl and 115±23μg/dl; mean plasma Fe level was 58.1±19.4 and 75.2±25.4μg/dl and mean erythrocyte Fe level was 4182±2314μg/ml and 7009±5228μg/ml, before and after ES transfusion. The differences between before and after ES transfusion in Cu, Zn and Fe levels were significant. Correlation between plasma and erythrocyte Fe levels was significant both before and after ES transfusion. Though Fe overload is a major cause of morbidity/mortality after ES transfusion, alterations in trace elements should also be considered when transfusing blood to infants and children.

The evaluation of possible role of endocrine disruptors in central and peripheral precocious puberty

Exposure to environmental chemicals can affect genetic and epigenetic molecular pathways and may cause altered growth and development. Among those exposures, endocrine-disrupting chemicals (EDCs) are of particular concern as humans are abundantly exposed to these chemicals by various means in every period of life. Several well-known environmental chemicals, including phthalates and bisphenol A (BPA), are classified as EDCs. These EDCs are suggested to play roles in early onset of puberty in girls. The aim of this study is to determine plasma phthalate (di(2-ethylhexyl)phthalate [DEHP] and its main metabolite mono(2-ethylhexyl)phthalate [MEHP]) and urinary BPA levels in girls with idiopathic central precocious puberty (CPP) and peripheral precocious puberty (PPP). This study was performed on newly diagnosed idiopathic central precocious puberty (CPP) patients (n = 42) and peripheral precocious puberty (PPP) (n = 42) patients, who were admitted to Keçiören Training and Research Hospital, Clinic of Pediatric Endocrinology between August 2012 and -July 2013. Nonobese healthy girls (n = 50) were used as the control group. Urinary BPA levels were not statistically different in control, PPP and CPP groups (medians 10.91, 10.63 and 10.15 μg/g creatinine, respectively; p > 0.05). Plasma DEHP levels were significantly higher in PPP group when compared to control. Plasma MEHP levels were not significantly different in control and PPP groups (p > 0.05). However, in CPP group, both plasma DEHP and MEHP levels were significantly higher than control and PPP groups. This study showed that phthalates might play a role in the occurence of CPP in girls.

Patients with psoriasis have an increased amount of epicardial fat tissue

BACKGROUND

Psoriasis is associated with coronary artery disease, and ischemic heart disease is associated with increased amounts of epicardial fat tissue (EFT). There has as yet been no study published on the accumulation of EFT in patients with psoriasis.

AIM

To compare epicardial fat accumulation and coronary artery calcium score (CACS) in patients with psoriasis and controls.

METHODS

We enrolled 38 patients with psoriasis and 38 controls matched for age and gender. Epicardial fat area (EFA) and CACS were evaluated by multidetector computed tomography.

RESULTS

Mean EFA in patients with psoriasis was significantly higher than in controls (13.8 ± 8.4 vs. 9.7 ± 6.4 cm(2) , respectively, P = 0.02), but mean CACS did not differ significantly between the two groups (55.2 ± 65.4 vs. 27.8 ± 29.3; P > 0.05). Multiple linear regression analyses indicated that EFA was significantly associated with waist circumference and presence of coronary artery calcification in both patients and controls, whereas EFA was significantly associated waist circumference and age in patients only (P < 0.05).

CONCLUSIONS

Patients with psoriasis had a higher level of EFA compared with controls, and EFA was independently associated with the presence of CAC in all study subjects.

Is androgenetic alopecia a risk for atherosclerosis?

BACKGROUND

Several studies have demonstrated the presence of an association between androgenetic alopecia (AGA) and cardiovascular disease. The aim of this study was to evaluate subclinical atherosclerosis in patients with AGA and healthy controls by the incorporation of carotid intima-media thickness (IMT) and high-sensitive C-reactive protein (hs-CRP) along with echocardiography (ECHO) and exercise electrocardiography (ExECG).

METHODS

We performed a case-control study in 50 male patients with AGA and 31 age-matched healthy male controls with normal hair status. Both the AGA patients and controls with a history of diabetes mellitus, cigarette smoking, hypertension, cardiovascular or cerebrovascular disease, and renal failure were excluded. AGA was classified according to the Hamilton-Norwood scale. Serum lipids, serum hs-CRP, total testosterone, and dehydroepiandrosterone sulphate were examined in all study subjects. Carotid ultrasonography was used to measure the IMT of the common carotid arteries (CCA). ECHO and ExECG were performed in all subjects.

RESULTS

IMT of the CCA was found to be significantly higher in patients with severe vertex pattern AGA when compared to patients with other patterns of AGA and healthy controls (P < 0.05). Hs-CRP in patients with any group of AGA was not significantly different from those healthy controls (P > 0.05). ECHO showed that cardiac structural and functional measures were in normal ranges. ExECG was also normal in all subjects.

CONCLUSION

Severe vertex pattern AGA should be considered to have an increased risk of subclinical atherosclerosis. For this reason, CCA IMT measurement can be recommended as a non-invasive and early diagnostic method.

Pregnancy in women with prosthetic heart valves

Pregnancy in women with mechanical valve prostheses has a high maternal complication rate including valve thrombosis and death. Coumarin derivatives are relatively safe for the mother with a lower incidence of valve thrombosis than un-fractionated and low-molecular-weight heparin, but carry the risk of embryopathy, which is probably dose-dependent. The different anticoagulation regimens are discussed in this review. When valve thrombosis occurs during pregnancy, thrombolysis is the preferable therapeutic option. Bioprostheses have a more favourable pregnancy outcome than mechanical prostheses but due to the high re-operation rate in young women they do not constitute the ideal alternative. When women with native valve stenosis need pre-pregnancy intervention, mitral balloon valvuloplasty is the best option in mitral stenosis, while the Ross operation or homograft implantation may be the preferable surgical regimen in aortic stenosis. (Neth Heart J 2008;16:406-11.).

Increased carotid artery intima-media thickness and impaired endothelial function in psoriasis

BACKGROUND

Psoriasis is associated with an increased risk of atherosclerosis. This study compared subclinical atherosclerosis of the carotid and brachial arteries in psoriasis vulgaris patients and healthy controls using high-resolution ultrasonography.

METHODS

We studied 43 psoriasis patients and 43 healthy controls matched for age and sex. Flow-mediated dilatation (FMD) and nitroglycerin-induced dilatation (NTD) of the brachial artery and intima-media thickness (IMT) of the common carotid arteries (CCA) were measured ultrasonographically. Diabetes mellitus, hypertension, renal failure, a history of cardiovascular or cerebrovascular disease were exclusion criteria. Subjects who were receiving lipid-lowering therapy, antihypertensive or anti-aggregant drugs, nitrates or long-term systemic steroids were also excluded.

RESULTS

The mean IMT values of the right, left and averaged CCA of the psoriasis patients were significantly higher, compared with the controls (0.607+/-0.144 mm vs. 0.532+/-0.101 mm, 0.611+/-0.157 mm vs. 0.521+/-0.117 mm, and 0.609+/-0.146 mm vs. 0.526+/-0.104 mm; P=0.006, P=0.003 and P=0.003, respectively). The mean FMD and NTD values of the psoriasis patients were significantly lower, compared with the controls (13.36+/-6.39 mm vs. 19.60+/-11.23 mm and 21.08+/-8.38 mm vs. 26.85+/-12.38 mm; P=0.002 and P=0.013, respectively). Multiple linear regression analysis revealed a significant association between psoriasis and the IMT, FMD and NTD. Moreover, the FMD in psoriasis patients was associated with disease duration.

CONCLUSION

Psoriasis patients had impaired endothelial function and thicker IMT of the CCA, compared with the healthy control subjects. The presence of psoriasis was an independent risk factor for subclinical atherosclerosis.

[Penetrating heart wounds. An analysis of 29 cases]

Twenty-nine cases, penetrating wounds to the heart, who were operated in the thoracic and cardiovascular surgery department of our University during January 1995-August 2000 were reevaluated. Twenty nine patients were men and the mean age was 22.6 (min 12, max 45). The cause of injury was stab wounds in 28 cases and gunshot wounds in 1 case. Besides the clinical findings; teleradiography, echocardiography were valuable for the diagnosis. Surgery was applied in emergent conditions for all cases. Interventions were performed 28 anterolateral thoracotomy, 1 bilaterally anterolateral thoracotomy and additionally 4 laparatomy were performed. The most frequent side of injury was right ventricule. Our mortality ratio was 17.2%, morbidity ratio 17.2%. We think that fast transportation, urgent diagnostic study and immediate surgical intervention important parameters which decrease of the mortality.

The expression of common fragile sites in peripheral blood lymphocytes of breast and colorectal cancer patients with aphidicolin

The frequency and distribution of aphidicolin induced common fragile sites was evaluated on chromosomes of peripheral blood lymphocytes in 10 breast and 10 colorectal cancer patients, and 10 healthy controls to determine correlation between specific fragile sites and cancer breakpoints. Fifty complete metaphases were screened from each culture and the results were evaluated by Student's t-test. The total number of fragile sites was found as 933 in breast cancer patients, 950 in colorectal cancer patients and 501 in control group. Both the number of aberrations per cell and number of aberrations per damaged cell were significantly higher in the patient groups. These findings indicate that genetic instability in the breast and colorectal cancer patients increased and fragile sites may play a critical role in the pathogenesis of breast and colorectal cancer.

Gossypol induced apoptosis in the human promyelocytic leukemia cell line HL 60

In human promyelocytic leukemia cell line HL60, apoptosis was induced by treatment with gossypol that is an inhibitor of protein kinase C. Gossypol acetic acid was added to HL 60 cells at 50, 100, 150 and 200 microM concentrations for six hours. Morphological features of apoptosis as well as internucleosomal DNA fragmentation were evaluated by light microscope, agarose gel electrophoresis and spectrofluorometric quantitation. Our results indicated that with the effective concentrations of gossypol (50 and 100 microM), apoptosis was induced in HL 60 cells.

Mutation analysis of BRCA1 and BRCA2 in Turkish cancer families: a novel mutation BRCA2 3414del4 found in male breast cancer

Since the identification of the BRCA1 and BRCA2 breast-ovarian cancer susceptibility genes, mutation analyses have been carried out in different populations. Here we screened 15 Turkish breast and breast-ovarian cancer families for mutations in both genes by conformation-sensitive gel electrophoresis (CSGE) and the protein truncation test (PTT), followed by DNA sequencing. Three families included a male breast cancer case, one without family history. Three germline mutations were identified, two in BRCA1 and one in BRCA2. The two BRCA1 mutations, 5382insC and 5622C-->T, were found in breast-ovarian cancer families. The BRCA2 3414delTCAG is a novel mutation detected in a site-specific breast cancer family that included 1 case of male breast cancer. These first results of Turkish families show that the frequency of germline BRCA1 or BRCA2 mutations appears to be high in families with at least 3 breast and/or ovarian cancer cases.

The in vitro effect of beta-carotene and mitomycin C on SCE frequency in Down's syndrome lymphocyte cultures

Down's syndrome (DS) has the highest incidence among chromosomal disorders and is a predisposing factor in acute leukemia pathogenesis. DS patients are sensitive to both physical and chemical inducers at the DNA level. Studies on beta-carotene, an antioxidant, suggested the there is a relationship between high beta-carotene diet and reduced tumor incidence in humans indicating that beta-carotene is a chemopreventive agent against cancer. Sister chromatid exchange (SCE) is known as a sensitive parameter among the genotoxicity tests. In this study, we aimed to investigate the in vitro effect of beta-carotene on SCE frequencies in 7 DS patients and 7 healthy controls aged between 0-16 years. A direct leukomogenic agent Mitomycin-C (MMC) was used as a powerful SCE inducer. Addition of MMC to the cultures alone resulted in a significant enhancement of SCE frequencies in both groups when compared to the spontaneous values. In the study, beta-carotene seemed to decrease MMC induced mean SCE/cell values, but did not have an effect on unstimulated cells. As this is a limited study, it is hard to conclude that beta-carotene is a chemopreventive agent in DS patients, although our results seem to support other investigators' reports.
