BACKGROUND: Patients with allergic rhinitis and bronchial hyperresponsiveness (BHR) may be at higher risk of developing asthma. OBJECTIVE: To investigate whether reactivity to aeroallergens in skin prick testing (SPT) and serum eosinophil cationic protein levels can be used to predict BHR in allergic rhinitis patients. METHODS: Fifty-nine consecutive patients with allergic rhinitis underwent SPTs using grass, tree, weed, parietaria, Alternaria, Aspergillus, mites, and cat and dog dander extracts. Methacholine challenge tests were performed using spirometry. RESULTS: Methacholine-induced BHR was detected in 23 patients (39%). Of 59 patients, 14 had 1 positive SPT response, 35 had 2 to 4 positive responses, and 10 had more than 4 positive responses. There was a significant inverse correlation between methacholine provocation concentration that caused a decrease in forced expiratory volume in 1 second of 20% (PC20) and the number of positive SPT responses (r = -0.28; P = .03). The BHR-positive patients had a mean of 4 positive SPT responses, whereas BHR-negative patients had a mean of 2.6 (P = .04). Nine BHR-positive patients (39%) and only 1 BHR-negative patient (3%) had more than 4 positive SPT responses (P < .001). There was no correlation between serum eosinophil cationic protein levels and methacholine PC20 doses. There was a strong association between hyperresponsiveness to methacholine and both cat and dog dander sensitivity (P < .001 and P = .001, respectively). CONCLUSIONS: Allergic rhinitis patients with SPT responses to a higher number of allergens are more likely to have BHR. Whether the number of positive SPT responses correlates with the risk of developing asthma in allergic rhinitis patients remains to be determined.  相似文献

Tumor necrosis factor-alpha (TNF-α) antagonists are employed increasingly during recent years in patients with active rheumatoid arthritis who do not respond to disease-modifying anti-rheumatic drugs. Contraindications such as infections, auto-antibody formation and hypersensitive reactions can be observed during the treatment with TNF-α antagonist drugs. Our case was a 52-year-old woman, followed by several centers for a period of 21 years with a seropositive, erosive and nodular RA diagnosis. Anti TNF-α treatment was commenced due to the failure to control the disease. During the treatment, a serious cellulite developed, which required hospitalization and surgical debridement as well as intravenous antibiotics treatment. Through the present case, we aimed to draw attention to the skin infection during the use of etanercept in a patient with RA.  相似文献

Although most childhood nephrotic syndromes respond to steroid treatment, steroid resistant nephrotic syndrome (SRNS) is also common and is particularly difficult to treat. This study investigated the role of glycosaminoglycans (GAG) in the pathogenesis and clinical course of nephrotic syndrome in children. Thirty-four children (21 males and 13 females, mean age 3.7±1.6 years) with steroid-sensitive nephrotic syndrome and 20 children with steroid-resistant nephrotic syndrome (12 males and 8 females, mean age 10.9±3.8 years; of the twenty, four had primary SRNS (FSGS) and the others had secondary SRNS) were included the study. Mean urine levels of GAG relative to creatinine (UGAG/UCr) in patients with SRNS (n=20, 113.01±78.46 mg g–1 Cr) and in patients experiencing the nephrotic period of steroid-sensitive nephrotic syndrome (n=34, 132.15±101.55 mg g–1 Cr) were both significantly higher than mean UGAG/UCr for control subjects (n=30, 51.83±47.66 mg g–1 Cr) (P<0.01 for both). Patients excreted significantly more GAG during the nephrotic period of steroid-sensitive nephrotic syndrome than during remission (132.15±101.55 vs 39.11±42.73 mg g–1 Cr, respectively; P<0.01). There was, however, no significant difference between UGAG/UCr for patients with steroid-resistant nephrotic syndrome and UGAG/UCr in the nephrotic period of steroid-sensitive nephrotic syndrome. Urine GAG excretion correlated significantly with the severity of proteinuria. The results suggest that GAG play a significant role in the pathogenesis of nephrotic syndrome but that GAG excretion is not a marker for response to steroid treatment in pediatric patients with this condition.  相似文献

Introduction

Sexual functioning has received little attention as an important aspect of patient care for those who have severe mental disorders.

Aim

The aim of this study is to compare sexual difficulties seen in Turkish psychiatric patients and healthy control subjects.

Methods

Study group consisted of outpatients in remission with schizophrenia (n = 84), bipolar affective disorders (n = 90), heroin addiction (n = 88), and healthy control group (n = 98). A sociodemographical data form and the Golombok Rust Inventory of Sexual Satisfaction were applied to all groups (N = 360).

Results

Half of the patient groups and 72.8% of control subjects reported that they had regular sexual life. The patients with heroin addiction complained about more problems in their sexual life than in the other groups. Controls (86.2%) felt more satisfied with their sexual life. Female patients with heroin addiction had statistically significant higher scores in nonsensuality subscale of Golombok Rust Inventory of Sexual Satisfaction. Female patients with schizophrenia and bipolar disorder had statistically significant higher scores in vaginismus subscale than in control group. Between the groups, male patients with bipolar disorder had higher score in most of the items except noncommunication and erectile dysfunction and also had higher total score than in the controls. More men (especially with heroin addiction) thought that their illness and drugs were responsible for their sexual problems, knew the effect of the illness and drugs on their sexual life, and asked questions to their psychiatrists about the problems more than women.

Conclusion

Patients with bipolar disorders and schizophrenia were unaware of effects of their medication on their sexual life. Finally, it was also found that clinicians in our country do not pay sufficient attention to the sexual problems of psychiatric patients.  相似文献

AimRisky sexual behavior associated with such sexually transmitted infections (STIs) as hepatitis B and C, herpes, Treponema pallidum, and Neisseria gonorrhoeae, is more frequent among psychiatric patients and parenteral drug abusers than the general population. The aim of this study was to investigate risky sexual behavior in psychiatric outpatients diagnosed with schizophrenia (SCH), bipolar disorder, and heroin addiction (HA), and to compare them with those observed in healthy controls.MethodsThe study group (N = 485; 234 females and 251 males) consisted of patients that consecutively presented to Bak?rkoy State and Training Hospital for Psychiatric and Neurological Diseases in Istanbul and normal healthy controls.Main Outcome MeasuresThe chi‐squared test was used for comparisons between groups and categorical variables. One‐way analysis of variance (post‐hoc Bonferroni test) was used for demographic data. A 22‐item questionnaire for collecting demographic, illness history, and sexual activity data, and a structured 23‐item form for collecting data on risky sexually behavior were administered to the participants.ResultsIn all, 10% of the participants had a positive history for STIs. The majority of risky sexual behaviors was observed among the HA patients. The frequency of being sexually assaulted and having homosexual acts among the SCH group were higher. None of the patients had a positive human immunodeficiency virus (HIV) test result. The frequency of positivity for hepatitis B and C markers was highest among the HA patients.ConclusionsThe provision of information and training about all STIs and risky sexual behavior should become routine in the treatment of mentally ill patients, especially those that abuse drugs.

Renovascular disease accounts for 8–10% of all cases of paediatric hypertension, whereas, in adults, its incidence is approximately 1%. The Turkish Paediatric Hypertension Group aimed to create the first registry database for childhood renovascular hypertension in Turkey. Twenty of the 28 paediatric nephrology centres in Turkey responded to the survey and reported 45 patients (27 girls, 18 boys) with renovascular hypertension between 1990 and 2005. The age at presentation ranged from 20 days to 17 years. The mean blood pressure at the diagnosis was 169/110 mmHg. Chief complaints of symptomatic patients were headache (38%), seizure (18%), epistaxis (4%), growth retardation (4%), cognitive dysfunction (4%), polyuria (2%), palpitation (2%), and hemiplegia (2%). Renovascular hypertension was found incidentally in 11 children. The diagnosis of renovascular hypertension was established with conventional angiography in 39 patients, MR angiography in three, CT angiography in two, and captopril diethylene triamine penta-acetic acid (DTPA) scintigraphy in one patient. Twenty-one children had bilateral renal artery stenosis and 24 had unilateral renal artery stenosis. Of these, 14 (31%) had fibromuscular dysplasia; 12 (27%) Takayasu’s arteritis; six (13%) neurofibromatosis; two (5%) Williams syndrome; one (2%) Kawasaki disease; one (2%) mid-aortic syndrome; one (2%) extrinsic compression to the renal artery, and eight (18%) unspecified bilateral renal artery stenosis. Hypertension was controlled with antihypertensive drugs in 17 patients. Percutaneous transluminal angioplasty (PTRA) or surgery had to be performed in 28 patients: PTRA in 16 patients, PTRA + surgery in one patient and surgery in 11 patients (four nephrectomies). The importance of vasculitic disease, especially Takayasu’s arteritis, should not be underestimated in children with renovascular hypertension.  相似文献

The goal of this study was to assess the long-term articular damage in adults with juvenile idiopathic arthritis (JIA) using the Rheumatoid Arthritis Articular Damage (RAAD) score and to determine any associations between the disease-related parameters and RAAD score. Thirty-eight adults identified with JIA at 18 years of age or older with disease duration of at least 5 years were assessed by means of the RAAD score. Patients were divided into three groups according to disease duration as 5-10 years (group 1), 11-15 years (group 2) and more than 16 years (group 3), and into three groups according to JIA subtypes as seropositive polyarticular (group A), seronegative polyarticular (group B), and oligoarticular (group C). Functional disability, functional status, disease activity and depression were measured by Health Assessment Questionnaire (HAQ), Steinbrocker classification, Disease Activity Score 28 (DAS 28), and Beck Depression Inventory, respectively. We investigated any possible associations between the RAAD score and groups, sex, age at onset of the disease, HAQ, Steinbrocker classification, DAS 28, and Beck Depression Inventory. We observed significant differences in RAAD scores according to groups A, B, C (p < 0.01), but not according to groups 1, 2, 3 or sex (p > 0.05). While the RAAD score correlated well with HAQ (p < 0.001), Steinbrocker classification (p < 0.001) and DAS 28 (p < 0.01), it did not correlate with age at onset of the disease (p > 0.05) or Beck Depression Inventory (p > 0.05). Seropositive polyarticular patients demonstrate the worst articular damage scores. Even though articular damage does not progress over time and JIA frequently has a benign course, care should be given to establishing regular follow-up periods and well-arranged treatments, especially for seropositive polyarticular groups, to maintain satisfactory long-term disease outcome throughout the lives of JIA patients.  相似文献

Hemophilia is a coagulation disorder characterized by acute hemorrhages into the musculoskeletal system, leading eventually to arthropathy and disability. We investigated the functional loss, namely disability, in hemophiliacs. The clinical and radiological characteristics of joint involvement were also evaluated. There were 31 patients between the ages of 3 and 18 years and 65 involved joints. The knees were the most commonly affected joints followed by the elbows and ankles. There was a positive correlation between the radiological and clinical evaluation scores; however, the clinical evaluation score did not correlate with age. The radiological score increased in conjunction with increasing age of the patients. We observed a significant relationship between the disability score and the clinical evaluation and radiological scores. These observations suggest that hemophilia is a life-long condition, with a high potential for functional disability if not promptly and adequately controlled. The main principle in the treatment of hemophilic arthropathy is the restoration of the patient’s lifestyle and mobility with a comprehensive multidisciplinary approach.  相似文献

Ductus venosus connecting the portal and embryonic venous circulation into the inferior vena cava has a crucial role in fetal circulation. The absence of ductus venosus is a rare anomaly, in which the umbilical vein connection to the venous system may be extrahepatic, bypassing the liver or intrahepatic via the portal venous system. We report three cases of ductus venosus agenesis with associated anomalies. In two of them the connection was directly to the right atrium, whereas the umbilical vein drained to the left internal iliac artery in the third case. © 2012 Wiley Periodicals, Inc.
