The validity and reliability of the Turkish version of the Fibromyalgia Impact Questionnaire

This study was undertaken to translate and adapt the Fibromyalgia Impact Questionnaire (FIQ) into the Turkish language and investigate its validity and reliability for Turkish female fibromyalgia (FM) patients. After translation into Turkish, we administered the FIQ and Health Assessment Questionnaire (HAQ) to 51 women with fibromyalgia. As well as sociodemographic characteristics, the severity of relevant clinical symptoms, e.g., pain intensity, fatigue, and sleep disturbance, were assessed by visual analog scales. A tender point score (TPS) was calculated from tender points conducted by thumb palpation. Test-retest reliability, internal consistency, and concurrent and construct validities of FIQ were evaluated. Test-retest reliability and internal consistency were good at 0.81 and 0.72, respectively. Correlation between FIQ and HAQ scores was 0.43, which was low but statistically significant. Significant moderate correlations were obtained between the FIQ items and severity of clinical symptoms (0.63-0.77), except TPS, 0.31. The FIQ is a reliable and valid instrument for measuring functional disability in Turkish female FM patients.

A tale of two countries: environmental impacts on social participation after spinal cord injury

STUDY DESIGN

Comparative analysis of survey data produced in two countries.

OBJECTIVES

To assess the degree to which environmental barriers impact social participation, and to identify the aspects of participation most affected.

SETTING

Community-dwelling individuals with spinal cord injury in the USA and Turkey.

METHODS

Subjects completed the Functional Independence Measure (FIM) motor score, the Craig Hospital Inventory of Environmental Factors (CHIEF), and the Craig Handicap Assessment and Reporting Technique (CHART). Analysis of co-variance was used to analyze CHIEF and CHART differences within and between country.

RESULTS

US subjects reported higher participation scores (CHART) and lower barriers (CHIEF), however, when controls for age, gender, time since injury and motor ability (FIM) were applied, country differences in reports of barriers were limited. Motor ability was the major predictor of participation, which was minimally affected by barriers.

CONCLUSION

Conceptualization and measurement issues may have been the reason for the minimal support for the hypothesis that environment affects participation. Suggestions for future research are made.

An experience from an outbreak of tinea capitis gladiatorum due to Trichophyton tonsurans

'Tinea corporis gladiatorum' describes a dermatophytosis transmitted mainly from close skin contact among wrestlers. Although tinea corporis is well recognized, no data are available for tinea capitis infections in wrestlers. After finding tinea capitis infection in a student wrestler, we aimed to search for possible ringworm infections among wrestlers in a wrestling boarding-school. Of the 32 wrestlers, 29, aged 12-18 years, were affected, of whom 22 had scalp involvement. Trichophyton tonsurans was isolated from 20 of the patients, and T. mentagrophytes from the remaining two. Isolated strains of dermatophytes were susceptible to terbinafine and itraconazole. The patients with tinea capitis received oral terbinafine for 4 weeks, and patients with more than two lesions but without scalp involvement received oral terbinafine for 2 weeks. Overall clinical and mycological cure rate was 72.4% and 70%, respectively, at assessment at week 6. The asymptomatic dermatophyte carrier rate was negative 1 year after control of the epidemic. Terbinafine seems to be an alternative drug for the treatment of tinea capitis caused by T. tonsurans; however, control of an outbreak may be very difficult and effective preventive measures should be considered.

Insulin-like growth factor-I gene polymorphism in acne vulgaris

BACKGROUND

Acne vulgaris is a multifactorial disease of the skin. Several studies have shown that elevated levels of serum insulin-like growth factor-I (IGF-I) correlate with overproduction of sebum and acne. Recently functional relationship between IGF-I (CA) polymorphism and circulating IGF-I levels in adults has been reported.

AIMS

The aim of our study was to investigate for the first time whether IGF-I (CA) polymorphism might be involved in the pathogenesis of acne or not.

METHODS

We included 115 acne patients and 117 healthy subjects to the study. The clinical grade of acne was assessed based on the Global Acne Grading System. Participants were questioned about diabetes mellitus, PCOS and other systemic disease. We searched for the IGF-I (CA) 19 polymorphism in this study. The IGF-I (CA) 19 polymorphism was performed by polymerase chain reaction.

RESULTS

We categorized the IGF-I (CA) 19 polymorphism area into three groups as lower than 192 bp, 192–194 bp and higher than 194 bp. We found that the frequency of genotype IGF-1 (CA) 19 gene was significantly different between control and acne patients (P = 0.0002). A significant association between IGF-I (CA) genotypes and severity of acne was found (P = 0.015). No significant difference was found between male and female patients (P > 0.05).

CONCLUSIONS

Our results suggest that IGF-I (CA) 19 polymorphism may contribute to a predisposition to acne in Turkish patients.

The relationship between arthritis and human parvovirus B19 infection

In order to evaluate the role of human parvovirus B19 in the etiopathogenesis of autoimmune diseases such as rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE), synovial fluid and blood specimens were collected at 1-month intervals from 20 patients with early synovitis (ES) and 31 with RA. Blood specimens were also collected from 25 patients with SLE, 25 with osteoarthritis (OA) as the diseased control group, and 50 healthy blood donors (HBD) as the healthy control group. Detection of B19 IgM and B19 IgG were performed by enzyme-linked immunosorbent assay from serum specimens, and B19 DNA was detected by polymerase chain reaction from synovial fluid samples. B19 IgM, B19 IgG, and B19 DNA were found in the three patients of the ES group. Subsequently, two of them were diagnosed with RA and one with SLE. B19 DNA was also detected in the synovial fluid of eight patients in the RA group. Of them, all were positive for B19 IgG and half were positive for B19 IgM. B19 IgM was not detected in either of the control groups. To define the role of B19 in the etiopathogenesis and prognosis of undiagnosed arthritis and other chronic inflammatory diseases such as RA and SLE, we need broader serial and prospective studies based on clinical and laboratory collaboration. In conjunction with case reports, these studies would also serve to detect other possible factors in the etiopathogenesis of chronic inflammatory diseases.

Hormonal responses to exercise stress test in patients with fibromyalgia syndrome

Twenty patients with fibromyalgia syndrome (FMS) and 20 matched healthy controls were subjected to an exercise stress test above their anaerobic threshold. Serum samples for the measurement of growth hormone (GH), insulin-like growth factor-1 (IGF-1), prolactin (PRL), adrenocorticotrophic hormone (ACTH) and cortisol were taken prior to and after the test at 30-min intervals. Compared to the controls, the patients with FMS displayed significantly lower basal GH levels and slightly, though significantly, higher prolactin levels. Following the exercise test there was a significant increase in the mean GH level in the patient group (P = 0.0474) and a significant decrease in the control group (P = 0.0286) 1 hour after the exercise. A slight decrease in ACTH levels in the control group was observed (P = 0.0002), but there was no significant change in FMS patients. Cortisol levels were significantly lower in both groups after the exercise (P = 0.0001). These results suggest the possibility of a perturbation in hormonal response to exercise in patients with FMS.

Seroprevalence of herpes simplex virus type 1 and type 2 in Turkey

BACKGROUND

Herpes simplex virus (HSV) infections are among the most common infectious diseases in humans. The prevalence of herpes simplex viruses type 1 (HSV-1) and type 2 (HSV-2) varies widely across the world. HSV-2 infection is the primary cause of genital herpes. It is highly prevalent in human populations in many parts of the world, and is the most common cause of genital ulcer disease worldwide. In spite of the large prevalence and growing incidence of herpes simplex infection (HSV-1 and HSV-2), relatively few data have been published regarding the seroprevalence of herpes simplex infection, while no data exist regarding the Turkish population.

METHODS

We aimed to investigate the prevalence of HSV-1 and HSV-2 in selected populations in Turkey. A cross-sectional study was conducted involving 2082 serum samples of 725 adults, 300 pregnant women, 200 blood donors, 483 sex workers and 110 patients with genital warts and 264 hotel staff in Istanbul, Turkey. All serum samples were assessed for HSV1 and HSV-2 IgG antibodies using an HSV-type specific, enzyme-linked immunosorbent assay (ELISA).

RESULTS

The prevalence of HSV-2 and HSV-1 antibodies was 4.8 and 85.3% in sexually active adults; 5.5 and 96% in blood donors; 5 and 98% in pregnant women, 17.3 and 93.6% in patients with genital warts; 8.3 and 97.3% in hotel staff; and 60% and 99% in sex workers.

CONCLUSION

These results confirm a higher prevalence of HSV infection than estimated, especially in high risk groups in Turkey. The high prevalence of HSV infection underlines the need for education among these populations.

Determination of self-incompatibility groups of sweet cherry genotypes from Turkey

Determination of S-allele combinations of sweet cherry genotypes and cultivars has importance for both growers and breeders. We determined S-allele combinations of 40 local Turkish sweet cherry genotypes using a PCR-based method. Ten different S-alleles were detected. Although the most common S-allele was S3, as also found in Western genotypes and cultivars, there were some differences in the frequencies of some S-alleles between Turkish and Western sweet cherry genotypes. According to their S-allele compositions, 30 local Turkish sweet cherry genotypes were assigned to 10 previously identified incompatibility groups. For the remaining genotypes, whose S-allele combinations did not fit to any previous incompatibility groups, three more incompatibility groups, XLII, XLIII and XLIV, were proposed. Results obtained from this study will help both sweet cherry growers and breeders to better manage these local Turkish sweet cherry genotypes in their orchards.

Milia en plaque

Milia en plaque is a rarely reported entity which is usually appearing in the auricular region. We describe a well-defined, U-shaped milia en plaque arising in the infraorbital area, and emphasize that it should be considered in the differential diagnosis of xanthalesma.

A systemic lupus erythematosus gene expression array in disease diagnosis and classification: a preliminary report

Systemic lupus erythematosus (SLE) is a clinically heterogeneous disease diagnosed on the presence of a constellation of clinical and laboratory findings. At the pathogenetic level, multiple factors using diverse biochemical and molecular pathways have been recognized. Succinct recognition and classification of clinical disease subsets, as well as the availability of disease biomarkers, remains largely unsolved. Based on information produced by the present authors' and other laboratories, a lupus gene expression array consisting of 30 genes, previously claimed to contribute to aberrant function of T cells, was developed. An additional eight genes were included as controls. Peripheral blood was obtained from 10 patients (19 samples) with SLE and six patients with rheumatoid arthritis (RA) as well as 19 healthy controls. T cell mRNA was subjected to reverse transcription and PCR, and the gene expression levels were measured. Conventional statistical analysis was performed along with principal component analysis (PCA) to capture the contribution of all genes to disease diagnosis and clinical parameters. The lupus gene expression array faithfully informed on the expression levels of genes. The recorded changes in expression reflect those reported in the literature by using a relatively small (5 ml) amount of peripheral blood. PCA of gene expression levels placed SLE samples apart from normal and RA samples regardless of disease activity. Individual principal components tended to define specific disease manifestations such as arthritis and proteinuria. Thus, a lupus gene expression array based on genes previously claimed to contribute to immune pathogenesis of SLE may define the disease, and principal components of the expression of 30 genes may define patients with specific disease manifestations.

The prevalence, aetiological agents and therapy of onychomycosis in patients with psoriasis: a prospective controlled trial

BACKGROUND

Nail involvement morphologically resembling onychomycosis frequently accompanies psoriatic lesions. The role of psoriasis as a predisposing factor for onychomycosis and the possible influence of psoriasis on responsiveness of onychomycosis to treatment are controversial.

AIM

To investigate the frequency of onychomycosis, the aetiological agents responsible for it, and the efficacy of terbinafine 250 mg/day in patients with psoriasis compared with controls in order to reveal the role of psoriatic process on fungal growth.

METHODS

Over a 1-year period, 168 patients with psoriasis and 164 nonpsoriatic controls were recruited. In the case of clinically suspected of fungal infection, further mycological investigations were performed. Systemic terbinafine therapy 250 mg daily for 12 weeks was administered to the patients with onychomycosis. Patients were followed up clinically and mycologically for 24 weeks.

RESULTS

Onychomycosis was diagnosed in 22 patients with psoriasis (13.1% of the psoriasis group, which constituted 28.6% of patients with suspicion of onychomycosis) and 13 controls (7.9% of control group; 40.6% of controls with suspicion of onychomycosis). The prevalence rates of onychomycosis were similar in both groups. The most commonly isolated fungi were dermatophytes in the psoriasis group and nondermatophytic moulds in controls. Dermatophytes were more common in psoriatic than control nails (P = 0.02). All patients in each group were cured at the end of the therapy.

CONCLUSION

It seems that nail psoriasis constitutes a risk factor not for onychomycosis, but specifically for dermatophytic nail infections. Because of the similar therapeutic results in each group, different antifungal treatment protocols may not be needed in psoriasis. However, to confirm this, new comprehensive studies are necessary.

Amyloidosis of the tongue with kappa light chain disease

A 70-year-old woman presented with a painful, red tongue with papules associated with xerostomia and systemic symptoms including weight loss, difficulty in swallowing and breathing, haemochezia and leg swelling. Biopsy from the tongue demonstrated amyloid deposits and, on further investigation, kappa chain disease was diagnosed. Primary systemic amyloidosis was diagnosed and the patient died within weeks of presentation.

Mal de Meleda: a new geographical localization in Anatolia

BACKGROUND

Mal de Meleda (MDM) is an autosomal recessive form of palmoplantar keratoderma first described on the Dalmatian island of Meleda. MDM has been observed in many other countries so that the origin of the MDM gene may be elsewhere than in Meleda.

OBJECTIVE

After identification of the first MDM patient during a medical visit, a study was planned to reveal other families with MDM in the Köprüçay region in Anatolia.

METHODS

The patient was interviewed with a questionnaire including a pedigree drawing. All the subsequent cases reported to be of MDM were visited for clinical examination and pedigree drawings.

RESULTS

Thirty-nine patients, 8 families and 2 additional cases with MDM were identified in a 50-km(2) mountainous region in Köprüçay canyon in Anatolia. The prevalent clinical features were nail involvement (80%), 'glove-and-sock' distribution of the keratoderma (60%), edema on the hands/feet (60%), conical tapering of the fingertips (60%) and hyperhidrosis on the palms and soles (50%).

CONCLUSION

To our knowledge, this is the largest series reported. The relationship between the patients in Meleda and those in Anatolia awaits discovery by further researches that will be carried out with the collaboration of dermatology, genetics and medical history departments.

The comparison of Nail Psoriasis Severity Index with a less time-consuming qualitative system

OBJECTIVE

Reliable assessment of severity in nail psoriasis is essential to document treatment responses in clinical trials and routine clinical usage. In this study the correlation between Nail Psoriasis Severity Index (NAPSI) and Cannavo's scoring system was assessed, and inter-rater correlation of NAPSI scores were evaluated.

MATERIALS AND METHODS

Forty-five patients with nail psoriasis were included. Target nails were selected and graded by the first dermatologist with both scoring systems. The nails were reevaluated by the second dermatologist with NAPSI.

RESULTS

The two systems were highly correlated (P < 0.001). For NAPSI inter-rater correlation was also significant (P < 0.001).

CONCLUSION

Our results showed that the qualitative and quantitative evaluations of the same rater were similar. Although the qualitative scoring system of Cannavo's is less time consuming than NAPSI, to suggest this system inter-rater correlations should be evaluated.

Chemosis as a presenting symptom of systemic lupus erythematosus

We present a case of chemosis (conjunctival edema) as an early manifestation of severe systemic lupus erythematosus affecting multiple organs, including the central nervous system and the kidneys.

Sigtuna score versus Apgar score: simple and practical evaluation of the newborn

In this prospective study, we investigated the relation between the Apgar and Sigtuna scores in 1605 newborns. In 169 of them, umbilical arterial blood specimens were analysed for blood gases. There were significant correlations between the Sigtuna and Apgar scores at 1, 5 and 10 minutes after birth (P less than 0.001). Umbilical arterial blood pH (pHua) values were shown to be correlated with both the Sigtuna and Apgar scores. The Sigtuna score was similar to the Apgar score in respect of sensitivity, specificity, positive predictive value and negative predictive value in relation to pH level. We conclude that because of the simplicity of the Sigtuna score, it may be used in place of the Apgar score to establish a rapid diagnosis of asphyxia.
