    CLINICAL CHARACTERISTICS and PROGNOSIS OF COLORECTAL SIGNET-RING CELL CARCINOMA

    JOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 2001
    Kook Lae Lee
    Background/aims, Colorectal signet-ring cell carcinoma (SRCC) is uncommon tumor. The aim of this study was to evaluate the clinical characteristics of primary and metastatic colorectal SRCC. Methods, We retrospectively examined the records of patients who had undergone surgery for colon cancer and was diagnosed pathologically as colorectal SRCC from 1988 to 2000. Results, Among 1812 patients with colorectal cancer examined, the number of patients with SRCC was 28 (1.5%); eight patients (28.6%) were metastatic and 20 patients (71.4%) were primary. Male to female ratio was 19:9 and mean age was 44.2 (primary, 42.5; metastatic, 48.3). Mean age of primary SRCC of rectosigmoid area was lower than that of ascending colon (37.4 vs. 54.5). The topographic incidences of primary SRCC were nine patients in rectum; five patients in sigmoid colon; six patients in ascending colon. Metastatic SRCC's were mostly found in splenic flexure and rectosigmoid area. Biopsy positive rate at first was 13 of 18 in primary SRCC, and 3 of 5 in metastatic SRCC. Five cases (55.6%) of primary rectal SRCC showed linitis plastica type. The stage of primary SRCC showed a preponderance of Astler,Coller C2 lesions; 3 (15%) were in B2, 1 (5%) was in C1, 14 (70%) were in C2, 2 (10%) were in D. One and two years survival of primary SRCC were 62.7 and 45.7%, respectively. Conclusions, Colorectal SRCC is rare among colon cancer and common in young age group especially which is primary or occurs in rectosigmoid area. The primary SRCC's were mostly found in advanced stage, and the prognosis might be poor. [source]


    In-Transit Metastasis From Primary Cutaneous Squamous Cell Carcinoma in Organ Transplant Recipients and Nonimmunosuppressed Patients: Clinical Characteristics, Management, and Outcome in a Series of 21 Patients

    DERMATOLOGIC SURGERY, Issue 4p2 2004
    John A. Carucci MD
    Background. In-transit metastases from cutaneous squamous cell carcinoma (SCC) may occur in organ transplant recipients and may indicate aggressive disease and poor prognosis. Objective. The objective of this study was to describe in-transit metastases from cutaneous SCC and to identify factors associated with this phenomenon in a series of 21 patients. We also attempted to evaluate outcome with respect to status as an organ transplant recipient or nonorgan transplant recipient. Methods. A multicenter case series of patients was reviewed; factors included clinical presentation, management, and outcome. Results. Twenty-one patients, 15 organ transplant recipients, and 6 nontransplant recipients with in-transit metastases were reviewed. In-transit metastases presented most commonly as discrete, dermal papules distinct from but in the vicinity of the primary tumor site. Histologic differentiation was variable. At a mean follow up of 24 months, 33% the transplant patients had no evidence of disease compared with 80% of nontransplant patients. Thirty-three percent were dead from disease and 33% were alive with nodal or distant metastases. In contrast, 80% of nonimmunosuppressed patients had no evidence of disease and none had died at mean follow-up of 24 months. Conclusion. In-transit metastasis from cutaneous SCC is a unique presentation of metastatic SCC, more commonly described in organ transplant recipients, and is associated with poor prognosis in that group. This description represents the largest experience with in-transit metastases from cutaneous SCC in the literature. [source]


    Clinical Characteristics as Predictors of Recurrent Alcohol-related Seizures

    ACADEMIC EMERGENCY MEDICINE, Issue 8 2000
    Niels K. Rathlev MD
    Abstract. Objective: To determine whether clinical data available in the emergency department can accurately predict a subset of patients at low risk of developing recurrent seizures following one or more initial alcohol-related seizures in the out-of-hospital arena. Methods: This was a retrospective secondary analysis of data obtained from the placebo arms of two prospective, randomized trials of drug treatments for the prevention of recurrent alcohol-related seizures. Subjects with and without one or more recurrent alcohol-related seizures during the study period were compared according to the following characteristics: 1) age, 2) gender, 3) daily ethanol consumption, 4) years of ethanol abuse, 5) previous alcohol-related seizure, 6) previous seizure of other etiology, 7) temperature, 8) heart rate, 9) systolic blood pressure, 10) diastolic blood pressure, 11) respiratory rate, and 12) ethanol level. Data were analyzed with t-tests and chi-square where appropriate. Results: One hundred five placebo-treated patients were analyzed and 31 (30%) developed recurrent alcohol-related seizures. None of the listed characteristics were statistically different between the two groups except for the initial ethanol level. Subjects with an ethanol level higher than 100 mg/dL were less likely (0%) to develop recurrent seizures than patients with a level equal to or below 100 mg/dL (36%) (p < 0.01). Conclusions: An initial ethanol level higher than 100 mg/dL was significantly associated with a low risk for recurrent alcohol-related seizures during the observation period. No other low-risk clinical characteristics could be identified. [source]

    Clinical Characteristics of Flexed Posture in Elderly Women

    JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 10 2003
    Lara Balzini PT
    Objectives: To investigate the relationships between the severity of flexed posture (FP), skeletal fragility, and functional status level in elderly women. Design: Cross-sectional study. Setting: Geriatric rehabilitation research hospital. Participants: Sixty elderly women (aged 70,93) with FP referred to a geriatric rehabilitation department for chronic back pain without apparent comorbid conditions. Measurements: Multidimensional clinical assessment included the severity of FP (standing occiput-to-wall distance) demographic (age) and anthropometric (height, weight) data, clinical profile (number of falls, pain assessment, Mini-Mental State Examination, Comorbidity Severity Index, Geriatric Depression Scale, Multidimensional Fatigue Inventory), measures of skeletal fragility (number of vertebral fractures by spine radiograph, bone mineral density (BMD), and T-score of lumbar spine and proximal femur), muscular impairment assessment (muscle strength and length), motor performance (Short Physical Performance Battery, Performance Oriented Mobility Assessment, instrumented gait analysis), and evaluation of disability (Barthel Index, Nottingham Extended Activities of Daily Living Index). Results: The severity of FP was classified as mild in 11, moderate in 28, and severe in 21 patients. Although there were no differences between FP groups on the skeletal fragility measurements, the moderate and severe FP groups were significantly different from the mild FP group for greater pain at the level of the cervical and lumbar spine. The severe FP group was also significantly different from the mild but not the moderate FP group in the following categories: clinical profile (greater depression, reduced motivation), muscle impairment (weaker spine extensor, ankle plantarflexor, and dorsiflexor muscles; shorter pectoralis and hip flexor muscles), the motor function performance-based tests (lower scores in the balance and gait subsets of the Performance Oriented Mobility Assessment), the instrumented gait analysis (slower and wider base of support), and disability (lower score on the Nottingham Extended Activities of Daily Living Index). The total number of vertebral fractures was not associated with differences in severity of FP, demographic and anthropometric characteristics, clinical profile, muscular function, performance-based and instrumental measures of motor function, and disability, but it was associated with reduced proximal femur and lumbar spine BMD. Conclusion: The severity of FP in elderly female patients (without apparent comorbid conditions) is related to the severity of vertebral pain, emotional status, muscular impairments, and motor function but not to osteoporosis, and FP has a measurable effect on disability. In contrast, the presence of vertebral fractures in patients with FP is associated with lower BMD but not patients' clinical and functional status. Therefore, FP, back pain, and mobility problems can occur without osteoporosis. Older women with FP and vertebral pain may be candidates for rehabilitation interventions that address muscular impairments, posture, and behavior modification. Randomized controlled trials are needed to support these conclusions. [source]


    Clinical Characteristics of Patients With Spontaneous or Inducible Ventricular Fibrillation Without Apparent Heart Disease Presenting with J Wave and ST Segment Elevation in Inferior Leads

    MASAHTKO TAKAGI M.D., Ph.D.
    Ventricular Fibrillation with J Wave in Inferior Leads. Introduction: The clinical characteristics of three patients with spontaneous or inducible ventricular fibrillation (VF) without apparent heart disease, who presented with J wave and ST segment elevation in inferior leads, are described. Methods and Results: All patients were male and experienced syncope. Their symptoms occurred at night or early in the morning. Holter ECG revealed infrequent premature ventricular complexes. Injection with disopyramide 2 mg/kg augmented ST segment elevation. Conclusion: These characteristics were very similar to those of patients with Brugada syndrome. These three patients with these specific features might have a variant of Brugada syndrome. [source]


    Clinical Characteristics of Portal Hemodynamics in Alcoholic Liver Cirrhosis

    ALCOHOLISM, Issue 2004
    Mami Hirata
    Background: Low incidence of reversal blood flow at the portal vein has been reported by measurement in larger and extrahepatic blood vessels but not in intrahepatic blood vessels in patients with liver cirrhosis. Moreover, there is little information regarding the incidence of reversal blood on the basis of the cause of liver cirrhosis. The aim of this study was to measure the reversal blood flow in the portal vein including intrahepatic branches in patients with alcoholic and viral cirrhosis. Methods: The blood flow in the portal vein and existence of portosystemic shunt were studied in 52 and 27 patients with alcoholic and viral cirrhosis, respectively, by Doppler ultrasonography. The parameters of liver function test and the prevalence of ascites and esophageal varices were compared between patients with and without reversal blood flow. Results: Reversal blood flow at the portal vein was found only in patients with only alcoholic cirrhosis (17 of 52 patients) but not in any patients with viral cirrhosis (0 of 27 patients; p < 0.05). The incidence of portosystemic ascites and red color of esophageal varices was also higher in patients with alcoholic cirrhosis with reversal blood flow in the portal vein compared with patients without reversal blood flow (p < 0.05). Conclusions: Reversal blood flow in the portal vein is a characteristic feature of alcoholic cirrhosis. The presence of reversal blood flow indicates severe liver diseases, and this feature may have prognostic importance for patients with alcoholic cirrhosis. [source]

    Defining the Clinical Characteristics of Peyronie's Disease in Young Men

    THE JOURNAL OF SEXUAL MEDICINE, Issue 2 2007
    Serkan Deveci MD
    ABSTRACT Introduction., Peyronie's disease (PD) is usually seen in men in their fifth decade of life. Aim., In this study, we investigated the characteristics of the disease in young men. Main Outcome Measures., The demographics, clinical features, and associated comorbidities of the patients with PD were retrospectively reviewed. Methods., The findings were compared between men with the disease who were under 40 years of age with those over 40 years. Statistical analyses were conducted to define differentiating features between these two groups. Results., Of the 296 patients, 32 were under the age of 40 years and 264 over 40 years. The mean duration of the disease was 2 ± 4 and 6 ± 8 months in the respective age groups. Fifty-six percent of the patients under the age of 40 years and 75% of the patients over this age presented with curvature (P < 0.01). Thirty-seven percent under 40 years and 12% men over 40 years had more than one plaque at presentation (P < 0.01). Dupuytren's contracture was seen only in patients over 40 years of age. Pain at presentation was found in 75% under the age of 40 years and in 65% over 40 years (P = 0.03). Trauma history was found in 18% under 40 years and in 5% over this age (P < 0.01). Statistical significant differences were found between the groups under and over the age of 40 years for hypertension (P < 0.01) and dyslipidemia (P < 0.01). Diabetes was noted in 50% of the patients under the age of 40 years and in 18% of the patients over this age (P < 0.001). Multivariate analysis of conditions associated in men with PD under 40 years of age showed statistical significant differences for diabetes (P = 0.015), presentation within 6 months (P = 0.004), and having multiple plaques (P = 0.008). Conclusions., Young men with PD are more likely to present at an earlier stage of the disease, to have diabetes, and to have more than one plaque at the time of presentation.

    Baseline Clinical Characteristics and Midterm Prognosis of STE-ACS and NSTE-ACS Patients with Normal Coronary Arteries

    ANNALS OF NONINVASIVE ELECTROCARDIOLOGY, Issue 1 2009
    Lukasz Mazurkiewicz M.D.
    Objective: We sought to compare clinical profiles and midterm prognosis of patients with normal coronary arteries presenting with ST-elevation ACS (STE-ACS) versus non-ST-elevation ACS (nSTE-ACS). Background: There are limited data regarding ACS in patients with normal coronary arteries, and especially clinical differences between ST-ACS and nSTE-ACS patients have not been evaluated sufficiently. Methods: The study group comprised 190 patients (mean age: 53.2 years, 63.1% males, 63.6% STE-ACS) presenting with ACS and normal coronary angiograms. The participants were evaluated in terms of 42 clinical variables. MACE [cardiac death (CD) and hospitalization for angina (HA)] were the study end points. Results: STE-ACS in comparison to nSTE-ACS patients were younger (P < 0.01), were more frequently males (P < 0.01), had more often infection prior to ACS (P < 0.01), higher hsCRP on admission (P < 0.01), and greater infarct size, measured by maximal troponin I (P < 0.01). By multivariate analysis in this subgroup, predictors of outcome were hsCRP (P = 0.03) and raised troponin I (P = 0.02). nSTE-ACS in comparison to STE-ACS patients were more obese (BMI, P < 0.01), had higher LDL cholesterol (P < 0.01), fasting glucose (P = 0.03). LDL cholesterol (P = 0.02) and fasting glucose (P = 0.03) emerged as independent predictors of outcome in these patients. Mean follow-up period was 25.4 months. STE-ACS patients had twice fewer MACE rate than nSTE-ACS patients [(1-CD, 12-HA; 11%) vs (1-CD, 16-HA; 25%), respectively, log rank P < 0.01]. Conclusions: STE-ACS and nSTE-ACS patients with normal coronary arteriography have different clinical profiles. In nSTE-ACS patients more pronounced metabolic abnormalities were identified, while in STE-ACS patients inflammatory background was more significant. [source]


    Clinical characteristics of inpatient adolescents with severe obsessive,compulsive disorder

    DEPRESSION AND ANXIETY, Issue 2 2006
    Gal Shoval M.D.
    Abstract Obsessive,compulsive disorder (OCD) is a common disorder in adolescents, usually treated in the outpatient setting. Our aim in this study was to evaluate the clinical characteristics of adolescents with severe OCD that required hospitalization. A total of 342 patients consecutively admitted to a psychiatric adolescent inpatient unit and 87 healthy volunteers were assessed by a semistructured interview for clinical diagnosis, suicide risk factors, aggression, ego defense mechanisms, and intelligence. Patients with OCD (n=40) were compared to other four diagnostic patient groups with psychotic, affective, conduct, and eating disorders, as well as to normal controls. Adolescent inpatients with OCD experienced less separation anxiety than all the other psychiatric groups (P < .01) and were less impulsive than controls (P < .001). They differed in aggressive/impulsive traits and hospital-related behaviors from other diagnostic groups. Adolescent inpatients with OCD consist of a unique subgroup in the inpatient unit in terms of their clinical characteristics and risk factors for suicide. These characteristics should be taken into account when developing a treatment plan for these difficult-to-treat inpatients. Depression and Anxiety 23:62,70, 2006. © 2006 Wiley-Liss, Inc. [source]


    Clinical characteristics of language regression in children

    DEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 8 2003
    Sy Wilson MD;
    The spectrum of language regression in childhood is incompletely understood. To describe the features of this disorder more fully, we reviewed the records of 196 consecutive children (143 males and 53 females) with language regression or perceived plateau evaluated between 1988 and 1994 by a child neurologist. Mean age at regression was 21.2 months and the mean interval to referral was 34.8 months. A trigger for the regression was identified in 74 of the children (38%) and was associated with a more rapid regression. Mean age at follow-up was 64 months (SD 55). Seventy per cent of the children became nonverbal, and 75% were cognitively impaired. Language regression was associated with a more global autistic regression in 93% of children. There was a history of seizures in 15% of the children. Some recovery occurred in 61% but only one child recovered fully. Improvement was more likely in the 49% who were entirely developmentally normal before the regression. We conclude that language regression in childhood is a serious disorder with significant long-term morbidity. [source]


    Prognostic Factors for the Surgery for Mesial Temporal Lobe Epilepsy: Longitudinal Analysis

    EPILEPSIA, Issue 8 2005
    Sang-Wuk Jeong
    Summary:,Purpose: Determining long-term prognostic factors of surgery for mesial temporal lobe epilepsy (MTLE) is important for identifying ideal candidates and predicting the prognosis for individual patients. We tried to identify the prognostic factors of anterior temporal lobectomy (ATL) for MTLE with longitudinal multivariate analysis. Methods: Two hundred twenty-seven patients with MTLE were included in this study. The primary outcome variable was patient status 1,5 years after surgery: seizure free, or not. Clinical characteristics and recent diagnostic modalities were considered as prognostic factors. Univariate and standard multiple logistic-regression analysis for outcome at 1 and 5 years after surgery and the generalized estimation equation (GEE) model for longitudinal multiple logistic regression of the 5-year follow-up period were used. Results: The seizure-free rate at 1 year was 81.1% and decreased to 75.2% at 5 years after surgery. By the univariate or standard multiple logistic-regression analysis, age at surgery or hippocampal sclerosis on magnetic resonance imaging (MRI) ipsilateral to surgery was significant for the postsurgical outcome. However, the longitudinal analysis by the GEE model revealed that younger age at surgery [odds ratio (OR), 0.59; 95% confidence interval (CI), 0.43,0.81], absence of secondarily generalized tonic,clonic seizure (2°GTCS; OR, 0.45; 95% CI, 0.26,0.79), and hippocampal sclerosis on MRI (OR, 2.44; 95% CI, 1.11,5.26) were significant predictors of a good surgical outcome. Conclusions: Age at surgery, presence of 2°GTCS, and hippocampal sclerosis on MRI are independent prognostic factors for ATL in MTLE. These findings suggest that MTLE is a progressive disorder, and surgical outcome is better when early ATL is performed. [source]


    Care provision for patients with eating disorders in Europe: what patients get what treatment where?

    EUROPEAN EATING DISORDERS REVIEW, Issue 3 2005
    Matthias Richard
    Abstract In this paper, we report on the similarities and differences between patients with eating disorders and the services provided to them across 80 centres participating in a European collaboration (COST Action B6). Differences in patient characteristics as well as differences in treatment regimen, especially length of treatment, are described. The relationship between patient characteristics, treatment setting and length of treatment is investigated by multilevel analysis. The findings show a rich diversity in service conditions and traditions across European countries. Patients with anorexia nervosa are mostly treated in inpatient settings, patients with bulimia nervosa are treated mostly as outpatients,with the exception of German-speaking countries. Day-patient settings were generally rare. Clinical characteristics of the patients,e.g. severity of symptoms or illness duration,contributed only little to the differences in treatment length (within as well as between centres), whereas organizational factors explained the largest proportion of between centre variability. The findings are discussed from a service research perspective. Copyright © 2005 John Wiley & Sons, Ltd and Eating Disorders Association. [source]


    Detection of the STAT5B,RARA fusion transcript in acute promyelocytic leukemia with the normal chromosome 17 on G-banding

    EUROPEAN JOURNAL OF HAEMATOLOGY, Issue 5 2008
    Manabu Kusakabe
    Abstract Acute promyelocytic leukemia (APL) is characterized by chromosomal rearrangements of 17q21, leading to fusion of the gene-encoding retinoic acid receptor alpha (RARA) with a number of alternative partner genes. Signal transducer and activator of transcription 5 beta (STAT5B) is one of the alternative partners. We report a rare case of APL with STAT5B,RARA fusion transcript and the normal chromosome 17 on G-banding. Administration of all trans -retinoic acid improved disseminated intravascular coagulation without decrease of the leukemia cells in his peripheral blood and bone marrow. The molecular mechanism of fusion between STAT5B and RARA by chromosomal rearrangement is discussed based on the data from genome database. Clinical characteristics of APL with STAT5B,RARA are also discussed. [source]


    Antiplatelet drug use preceding the onset of intracerebral hemorrhage is associated with increased mortality

    FUNDAMENTAL & CLINICAL PHARMACOLOGY, Issue 3 2007
    Karine Lacut
    Abstract Recent studies highlight the contribution of antiplatelet therapy to clinical severity and increased mortality of intracerebral hemorrhage (ICH) but results are discrepant. The aim of this report was to evaluate the association between antiplatelet drug use preceding the onset of ICH and the mortality, assessed at regular intervals, among patients with acute ICH. We analyzed data from a randomized study which enrolled consecutive patients with a documented acute ICH to evaluate the efficacy of intermittent pneumatic compression of the legs in venous thrombosis prevention. Clinical characteristics and treatment used before the onset of ICH were checked at the time of inclusion. Mortality was assessed at regular intervals until 3 months after ICH diagnosis. Among 138 patients included in this report, 30 were current users of antiplatelet therapy at the time of ICH; they were significantly older and less frequently heavy drinkers than non-users of antiplatelet drugs. Mortality rates were 20% at 8 days, 40% at 1 month, and 47% at 3 months among antiplatelet drug users compared with 6.5%, 13% and 19% among non-users. The corresponding estimated risks for mortality related to antiplatelet drug use were 3.6 (95% CI 1.1,12), 4.5 (95% CI 1.8,11), and 3.6 (95% CI 1.5,8.6). Adjusted for age, hypertension and alcohol over use, antiplatelet therapy remained significantly associated with an increased mortality rate of acute ICH. Current antiplatelet drug use preceding the onset of ICH is associated with increased short-term ICH mortality, independently of age. [source]


    NSAID-related upper gastrointestinal bleeding: are risk factors considered during prophylaxis?

    INTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 5 2006
    D. Dincer
    Summary The purposes of this study were to evaluate the effect of nonsteroidal anti-inflammatory drugs (NSAIDs) on acute nonvaricose upper gastrointestinal bleeding (ANUGIB) and establish whether the NSAID-prescribing physicians take precautions to prevent or reduce GI ulcerations. Clinical characteristics, causes of bleeding and clinical outcomes of patients hospitalised in our gastroenterology clinic with ANUGIB were recorded prospectively over a 1.5-year period. NSAIDs, including aspirin, were used by 127 of 168 patients (73%). Among the NSAID users, 100 patients (78%) had at least one risk factor for serious adverse GI events related to NSAIDs. Only two patients were using proton pump inhibitors and one patient was using H2 receptor blocker of the high-risk group for GI side effects of NSAIDs. NSAIDs have an important effect on GI bleeding, and it seems that risk factors are underestimated by physicians. [source]


    Characteristics of skin aging in Korean men and women

    INTERNATIONAL JOURNAL OF COSMETIC SCIENCE, Issue 1 2005
    J. H. Chung
    Introduction Korea is located between Japan and Mainland China. The people of these three countries have similar appearances and it is difficult to differentiate between them. Although the population of Asia is more than half of the total population of the Earth, the inherent characteristics of Asian skin have not been well investigated. Commercial markets for cosmetics and drugs for photoaged skin are rapidly expanding in many Asian countries. Therefore, many investigators in the field of dermatology and cosmetology have become interested in brown Asian skin. Clinical characteristics of skin aging and photoaging in Asians Skin aging can be divided into two basic processes: intrinsic aging and photoaging [1]. Intrinsic aging is characterized by smooth, dry, pale, and finely wrinkled skin, whereas photoaging, which indicates premature skin aging in chronically photodamaged skin, is characterized by severe wrinkling and irregular pigmentation. The pattern of wrinkling in Asians seems to differ from that in Caucasians. Asians have coarser, thicker and deep wrinkles, particularly in the forehead, perioral and Crow's foot areas. In contrast, Caucasians usually have relatively fine cheek and Crow's foot wrinkles. The reasons for these differences are not known and need further investigation. There are racial, ethnic and genetic differences, and differences of skin structure and function, between the brown skin of Asians and the white skin of Caucasians. As Asian skin is more pigmented, acute and chronic cutaneous responses to UV irradiation differ from those in white skin. Many people believe, based on clinical impressions, that the main process of photoaging in Asians involves pigmentary changes, rather than wrinkling. However, no study has been performed to confirm this belief. Risk factors for skin wrinkles and their relative risks in Korean skin [2] Various factors such as age, sun-exposure, and smoking are known to be important risk factors for wrinkles. However, the relative risks of each factor on wrinkles in the brown skin of Asians have not been investigated, and they could differ from those in Caucasians. An evaluation system for skin wrinkling is necessary for Asian skin [3]. Thus, we developed an eight-point photographic scale for assessing wrinkles in both Korean genders [2]. This scale can probably be applied to the populations of other Asian countries, at least to the Japanese and Chinese. The pattern of wrinkles in both genders appears to be similar. Age Age is an important risk factor for wrinkling in Asians, as in Caucasians. Korean subjects in their 60s showed a 12-fold increased risk of wrinkling, while subjects in their 70s have a 56-fold increased risk compared with young age group. UV light It is well known that the UV component in sunlight can cause and accelerate photoaging. The pigmented skin of Asian may better protect skin from acute and chronic UV damage. However, we found a strong association between sun-exposure and the development of wrinkling in Koreans. It was found that sun exposure of more than 5 h per day was associated with a 4.8-fold increased risk in wrinkling versus less than 2 h of sun-exposure in Koreans. Estrogen deficiency Korean females have more wrinkles than men, after controlling for age, sun exposure, and smoking, it was found that they have a 3.6-fold increased risk of developing wrinkles than their male counterparts [2]. It has also been reported, that the relative risk for wrinkling in women is higher than in men as for in white Caucasians [4]. The reason why women show more wrinkles remains to be determined. It is possible that a reduction in skin collagen because of estrogen deficiency in postmenopausal woman may aggravate wrinkling severity. Korean women with more than 10 years since menopause showed a 3.9-fold higher risk of wrinkling than the women 5 years of beyond menopause [5]. We demonstrated that women with a history of HRT have a significantly lower risk, more specifically, one fifth of the risk of facial wrinkling relative to those who had no history of HRT. Interestingly, we found that wrinkle severity significantly increased with an increasing number of full term pregnancies. The relative risk for severe wrinkling is increased by approximately 1.8-fold per full term pregnancy. Smoking It is known that smoking causes skin wrinkling in Caucasians, and that it plays no role in Blacks [6, 7]. Koreans with have a smoking history of more than 30 pack years showed a more than 2.8-fold increased risk of wrinkles [2]. The relative risks of wrinkles associated with a 30,50 pack-years history of smoking were 2.8- and 5.5-fold, respectively. Dyspigmentation in Asian skin To follow pigmentary changes, six photographic standards for both genders were developed for Korean skin, to produce a 6-point scale [2, 8]. Hyperpigmented spots, mostly lentigines, were prominent among women, while seborrheic keratosis tended to be more prominent in men. Seborrheic keratosis in Korean men Seborrheic keratoses (SKs) are benign cutaneous tumors. They have diverse clinical and histopathological appearances and are very common in the elderly (over 50 years old). The etiology of SKs is not well understood, although patients with a great number of lesionsshow a familial trait with an autosomal dominant pattern, and human papilloma virus has been suggested as possible cause because of verrucous appearance of the lesions. Exposure to sunlight has been suggested to be a risk factor for SKs. However, there is still some debate in terms of the role of sunlight. Recently, we have investigated the clinical characteristics of SKs and relationship between SKs and sunlight exposure in Korean males [9]. The prevalence of SKs in Koreans increases with age; it rose from 78.9% at 40 years, to 93.9% at 50 years and 98.7% in those over 60 years. Exposed areas, i.e. the face, neck and dorsum of the hands, demonstrate a significant increase in the prevalence of SKs by decade, whereas partly exposed areas, although SKs tended to increase in prevalence with age, this trend was not significant. When the estimated body surface area (BSA) is taken into account, the number of SKs on both the face and dorsum of the hands (0.51 ± 0.08 per 1% BSA) was over-represented compared with the trunk. SKs were also concentrated on the neck (0.38 ± 0.07 per 1% BSA) and in the V-area (0.47 ± 0.09 per 1% BSA). Outer forearms also showed 3-fold more SKs per unit area than neighboring arms and inner forearms, which are classified as partly exposed area (0.09 ± 0.02, 0.03 ± 0.01, respectively). The total area covered by SKs on exposed area also became significantly larger with aging than on intermittently exposed areas. These results indicate that exposure to sunlight might be related to SK growth. Our results indicated that excessive sun exposure is an independent risk factor of SKs. After controlling for age, smoking, and skin type, subjects with a sun exposure history of more than 6 hours per day showed a 2.28-fold increased risk of having severe SKs (n , 6) compared with those exposed for less that 3 h per day. These findings indicated that sun-exposure may play an important role in SK development. In summary, SKs are very common in Korean males and represent one of the major pigmentary problems. SKs concentrate on exposed skin, especially on the face and dorsum of the hands. Both age and lifetime cumulative sunlight exposure are important contributing factors and may work in a synergistic manner. Conclusion Many people tend to believe that wrinkles are not a prominent feature of Asian photoaged skin, and that dyspigmentation is a major manifestation in Asian skin. Contrary to this impression, wrinkling is also a major problem in the photoaged skin of Asians, and Korean people showing severe pigmentary changes usually tend to have severe wrinkles. In conclusion, the wrinkling patterns and pigmentary changes of photoaged skin in East Asians differ from those of Caucasians, and the relative risks of aggravating factors may be different from those of Caucasian skin.

    Clinical characteristics of basal cell carcinoma in a tertiary hospital in Sarawak, Malaysia

    INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 2 2010
    Felix Boon Bin Yap MD MRCP
    Background, Basal cell carcinoma (BCC) is the most common skin cancer among Orientals. Data on this malignancy is lacking in Malaysia, prompting a retrospective study to determine the clinical characteristics in the skin clinic, Sarawak General Hospital between 2000 and 2008. Methods, Demographic data and clinical features of 64 histopathologically proven BCC from 43 patients were retrieved. Statistical analysis was performed comparing the clinical characteristics based on the region of involvement and gender. Results, The mean age of presentation was 60.9 years. Male to female ratio was 1.05. Majority of the patients were Chinese (44.2%) followed by Malays (32.6%), Bidayuhs (14.0%) and Ibans (6.9%). Nodular BCC accounted for 95.3% of cases while 4.7% were superficial BCC. All the nodular BCC were pigmented. Ulceration was noted in 18%. There were 82.8% of BCC on the head and neck region and 17.2% on the trunk and limb region. BCC on the latter region were larger (mean 35.0 cf. 14.4 mm, p < 0.001) and ulcerated (45.5% cf. 11.3%, p = 0.01). Superficial BCC were also more frequently encountered in this region (18.2% cf. 1.9%, p = 0.02). Compared to women, men had larger BCC (mean 21.1 cf. 13.3 mm, p = 0.03) and kept them for a longer duration (mean 21.6 cf. 13.3 months, p = 0.04). Conclusion, Clinical characteristics of BCC in Sarawak were similar to other Asian studies. Additionally, BCC on the trunk and limbs and in men were larger, ulcerative and long standing warranting better efforts for earlier detection. [source]


    Clinical characteristics of normotensive renal transplant recipients with microalbuminuria and effects of angiotensin II type I receptor antagonist on urinary albumin excretion

    INTERNATIONAL JOURNAL OF UROLOGY, Issue 8 2004
    SHIGERU SATOH
    Abstract Aim:, Microalbuminuria is typically observed in renal transplant recipients with systemic hypertension. The effects of angiotensin II type 1 receptor antagonist (losartan) on the hypertensive recipients have been evaluated. However, the clinical background of normotensive recipients with microalbuminuria and the effect of losartan administration in those subjects have not been clarified. One of the two purposes for the present study was to investigate the clinical characteristics of normotensive recipients with microalbuminuria. The other was to evaluate the effect of losartan on urinary excretion of albumin in these patients. Methods:, The clinical data and the change of the single kidney glomerular filtration rate (GFR) for the graft by radionuclide study were assessed in 13 normotensive recipients with microalbuminuria. These were compared with the data of 13 normotensive patients without microalbuminuria. The 13 recipients with microalbuminuria were treated with losartan for one year and urine excretion of albumin, N-acetyl-,-D-glucosaminidase (NAG) and serum creatinine (S-Cr) levels were measured. Results:, The GFR of the grafts from donors to recipients significantly increased (30.9 to 55.2 mL/min) in microalbuminuric recipients, but did not significantly increase in the non-microalbuminuric recipients. Decreases of the urinary excretion rate of albumin (351 ± 261 at baseline to 158 ± 14 mg/gCr at 12 months), NAG (13 ± 5 to 10 ± 3 IU/gCr) and S-Cr (1.7 ± 0.6 to 1.5 ± 0.4 mg/dL) were observed in the microalbuminuric recipients with losartan administration. Conclusions:, The present study suggests that an increased single kidney GFR of the graft from the donor in situ to the recipient might be a cause of microalbuminuria in normotensive recipients. The one-year effects of losartan were observed in terms of the decrease in urinary excretion of albumin, NAG and S-Cr levels. [source]


    Long-Term Results of Heart Transplantation for End-Stage Valvular Heart Disease

    JOURNAL OF CARDIAC SURGERY, Issue 5 2009

    However, the outcomes of heart transplantation for patients with end-stage valvular heart disease are less well reported. This is a substantial group of patients, many of whom have had previous cardiac surgery. They therefore may be considered a subgroup with a poor prognosis. This study reports on the outcomes of heart transplantation for patients with end-stage valvular heart disease. Patients and methods: From March 1989 to December 2004, 75 consecutive adult heart transplantations were performed for end-stage valvular heart disease. Clinical characteristics were retrieved from a computerized database. Results: The early mortality risk in heart transplantation for end-stage valvular heart disease was 13%, compared to 8% for other indications (p = 0.12). The main causes of early death were rejection (20%) and right ventricular failure (20%). The total follow-up time was 415 patient-years. During the follow-up, another 23 patients died (55/1000 patient-years of late mortality rate), mostly due to infection (43%) and multiorgan failure (22%). Multivariable analysis demonstrated that increased waiting time to heart transplantation correlated with increased survival (HR = 0.998, p = 0.04). The survival at 1, 5, 10, and 15 years was 70%, 64%, 56%, and 46% compared to 78%, 68%, 53%, and 41% for other indications, respectively (p = 0.5). Conclusion: The outcomes of heart transplantation for patients with end-stage valvular heart disease are similar to those for other patients. Apparently, the longer the waiting time to heart transplantation the better the outcome becomes. [source]


    Triggering Pulmonary Veins: A Paradoxical Predictor for Atrial Fibrillation Recurrence After PV Isolation

    JOURNAL OF CARDIOVASCULAR ELECTROPHYSIOLOGY, Issue 4 2010
    YVES DE GREEF M.D.
    Triggering Pulmonary Veins and Recurrence After Ablation.,Purpose: To identify procedural parameters predicting recurrence of atrial fibrillation (AF) after a first circumferential pulmonary vein isolation (CPVI). Methods: One hundred seventy-one patients undergoing CARTO-guided CPVI for recurrent AF with a left atrial (LA) diameter <45 mm were studied. Follow-up (symptoms and 7-day Holter) was performed at 1 and 3 months and every 3 months thereafter. Clinical and procedural characteristics between successful patients and patients undergoing repeat ablation were compared. In addition, procedural parameters of the first procedure were compared with parameters during repeat ablation. Results: After first CPVI, 80% of patients were free of AF without antiarrhythmic drugs after a follow-up (FU) of 28 ± 11 months (N = 136). Thirty-five patients (20%) had recurrence of AF of which 25 underwent repeat ablation (N = 25). Clinical characteristics did not differ between the successful and repeat group. A triggering vein during the index procedure was significantly more observed in the repeat group (56% vs 11%, P < 0.001). At repeat ablation, 2.6 ± 1.2 veins per patient were reconnected. Whereas there was no preferential reconnecting PV, all PVs triggering at index were reconnected (100%). Conclusions: (1) In patients with symptomatic recurrent AF, the presence of a triggering pulmonary vein during ablation is a paradoxical predictor for AF recurrence after PV isolation. (2) The consistent finding of reconnection of the triggering PV at repeat ablation, suggests that, in these patients, the triggering PV is the culprit vein and that reconnection invariably results in clinical AF recurrence. (3) The present study advocates a strategy of even more stringent PV isolation in case of a triggering PV. (J Cardiovasc Electrophysiol, Vol. 21, pp. 381,388, April 2010) [source]


    Left Ventricular Lead Proximity to an Akinetic Segment and Impact on Outcome of Cardiac Resynchronization Therapy

    JOURNAL OF CARDIOVASCULAR ELECTROPHYSIOLOGY, Issue 6 2006
    DANIEL ARZOLA-CASTANER M.D.
    Background: Previous studies report that the optimal pacing site for cardiac resynchronization therapy (CRT) is along the left ventricular (LV) lateral and postero-lateral (PL) wall. However, little is known regarding whether pacing over an akinetic site impacts the contractile response and long-term outcome from CRT. Methods and Results: A total of 38 patients with ischemic cardiomyopathy were studied for their acute hemodynamic and 12-month clinical response to CRT. The intraindividual percentage change in dP/dt (%,dP/dt), over baseline, was derived from the mitral regurgitation (MR) Doppler profile with CRT on versus off. Two-dimensional echocardiography was used for myocardial segmentation and determinination of akinetic sites. LV lead implant site was determined using angiographic and radiographic data and categorized as being "on" (group 1) or "off" (group 2) an akinetic site. Long-term response was measured as a combined endpoint of hospitalization for heart failure and/or all cause mortality at 12 months. Time to primary endpoint was estimated by the Kaplan-Meier method. Clinical characteristics and acute hemodynamic response was similar in both (group 1 [n = 14]; %,dP/dt 48.8 ± 67.4% vs group 2 [n = 24]; %,dP/dt 32.2 ± 40.1%, P = 0.92). No difference in long-term outcome was observed (P = 0.59). In contrast, lead placement in PL or mid-lateral (ML) positions was associated with a better acute hemodynamic response when compared to antero-lateral (AL) positions (PL, %,dP/dt 45.7 ± 50.7% and ML, %,dP/dt 45.1 ± 58.8% vs AL, %,dP/dt 2.9 ± 30.9%, respectively, P = 0.014). Conclusion: LV lead proximity to an akinetic segment does not impact acute hemodynamic or 12-month clinical response to CRT. [source]


    Clinical characteristics and microbiota of progressing slight chronic periodontitis in adults

    JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 11 2007
    Anne C. R. Tanner
    Abstract Aim: This study sought clinical and microbial risk indicators for progressing slight periodontitis. Material and Methods: One hundred and seventeen periodontally healthy or slight periodontitis adults (20,40 years) were monitored clinically at 6-month intervals followed by supragingival cleaning. Inter-proximal sites with >1.5 mm increase in clinical attachment over 18 months were considered disease active. Subgingival plaque was analysed by 78 16S rDNA and 38 whole-genomic DNA probes and by PCR to Porphyromonas gingivalis and Tannerella forsythia. Characteristics were compared between active and inactive subjects. Results: Twenty-two subjects showed disease activity principally at molars. Mean baseline gingival and plaque indices, bleeding on probing, probing depth and clinical attachment level (CAL) were higher in active subjects. DNA probes detected species and not-yet-cultivated phylotypes from chronic periodontitis, although few species were associated with active subjects. By PCR P. gingivalis (p=0.007) and T. forsythia (p=0.075) were detected more frequently during monitoring in active subjects. Stepwise logistic analysis associated baseline levels of gingival index, clinical attachment and bleeding with subsequent clinical attachment loss. Conclusions: Gingivitis and CAL were significantly associated with progressing slight periodontitis in 20,40-year-old adults. Species associated with moderate and advanced chronic periodontitis were detected in slight periodontitis. [source]


    Efficacy of ribavirin plus interferon-, in patients aged ,60 years with chronic hepatitis C

    JOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 7 2007
    Takashi Honda
    Abstract Background:, In Japan, patients with hepatitis C virus (HCV)-associated liver disease are getting older, and thus the number of deaths due to such disease is increasing. The efficacy of combination therapy with ribavirin and interferon for chronic HCV infection in elderly patients has not been fully clarified. The aim of the present study was to evaluate the efficacy and tolerability of combination therapy in such patients. Methods:, Two hundred and twenty consecutive patients with chronic hepatitis C were treated with combination therapy. These patients were divided into two groups according to age: patients , 60 years (n = 66) and patients < 60 years (n = 154). Clinical characteristics, the sustained virologic response (SVR) rate obtained by intention-to-treat analysis, and the rate of reduction or discontinuation of ribavirin were compared between the two groups. Results:, The ribavirin discontinuation rate was significantly higher in the patients aged ,60 years than in the patients aged <60 years. However, the SVR rates did not differ significantly between patients aged ,60 years and those aged <60 years (31.8% vs 38.3% by intention-to-treat analysis). According to multivariate analysis, genotype and HCV viral load were significantly associated with SVR while patient age did not affect SVR. Conclusions:, Treatment of chronic hepatitis C with combination therapy was comparably effective between patients aged ,60 years and those aged <60 years, although the ribavirin discontinuation rate was higher among the older patients than the younger patients.

    Incidence and Predictors of Major Vascular Complications after Percutaneous Coronary Intervention in the Glycoprotein IIb/IIIa Platelet Inhibitor Era

    JOURNAL OF INTERVENTIONAL CARDIOLOGY, Issue 2 2004
    RICHARD KONSTANCE M.D.
    Since the introduction of platelet glycoprotein (GP) IIb/IIIa inhibitors, reports of vascular complications after percutaneous coronary intervention (PCI) have focused on bleeding and the need for surgical repair, whereas specific major vascular complications have been less consistently identified. Moreover, data from clinical trials may lack applicability to the general population. The purpose of this study was to determine the incidence of major vascular complications after PCI and to identify associated risk factors in patients routinely receiving GP IIb/IIIa inhibitors. During a 12-month period, 1,634 consecutive patients underwent PCI at a single institution. Clinical characteristics and procedural data were collected prospectively; data regarding vascular sheath removal were obtained retrospectively. Univariate and multivariable regression methods were used to identify independent predictors of major vascular complications. Major vascular complications occurred in 2.9% of patients. Multivariable analysis revealed advanced age (odds ratio [OR] 1.05, P = 0.0025) and female sex (OR 2.9, P = 0.0002) as clinical characteristics associated with major vascular complications, whereas hypertension had an inverse relationship (OR 0.46, P = 0.013). Procedural factors included use of the following: stents (OR 5.59, P < 0.0001), vascular sheaths >6F (OR 3.25, P = 0.016), and mechanical clamp (OR 2.71, P = 0.0012). The presence of a hematoma >4 cm2 had a positive predictive value of 12% for major vascular complications. The incidence of major vascular complications in this large, single-center study from the GP IIb/IIIa inhibitor era is consistent with data from the pre-GP IIb/IIIa inhibitor era and recent randomized trials.

    GB virus C and TT virus infections in Japanese patients with autoimmune hepatitis

    JOURNAL OF MEDICAL VIROLOGY, Issue 2 2002
    Shuhei Nishiguchi
    Abstract The association of the newly identified viruses, GB virus C (GBV-C) and TT virus (TTV), with autoimmune hepatitis remains to be elucidated. Sera from 20 Japanese patients with autoimmune hepatitis and 50 volunteer blood donors were assayed for GBV-C RNA, antibodies to the GBV-C second envelope protein (E2), and TTV DNA. GBV-C RNA was examined by reverse-transcription polymerase chain reaction (PCR). Anti-GBV-C E2 (a marker of past infection) was tested by an enzyme-linked immunosorbent assay. TTV DNA was amplified by PCR using two different sets of primers: one derived from the original N22 sequence (Set A) and the other from the untranslated region (Set B). None of the patients or controls had GBV-C RNA. Anti-GBV-C E2 was found significantly more often in patients with autoimmune hepatitis (3/20) than in controls (1/50; P,=,0.034). The prevalence of TTV DNA detected by primers Set A and that detected with either Set A or B were similar among patients with autoimmune hepatitis (4/20 and 16/20, respectively) and controls (9/50 and 40/50, respectively). Clinical characteristics did not differ in association with any of these viral markers. Of the 13 TTV isolates amplified with Set A, seven were classified as genotype 1a, four as genotype 1b, and 2 as genotype 3; no particular strain was associated with autoimmune hepatitis. These findings provide no compelling evidence that GBV-C or TTV has a pathogenic role in autoimmune hepatitis. J. Med. Virol. 66:258,262, 2002. © 2002 Wiley-Liss, Inc. [source]


    Clinical characteristics of perforated pyometra and impending perforation: Specific issues in gynecological emergency

    JOURNAL OF OBSTETRICS AND GYNAECOLOGY RESEARCH (ELECTRONIC), Issue 3 2010
    Yu-Che Ou
    Abstract Objective:, To evaluate the clinical characteristics of pyometra and the differences between perforated pyometra and early-drained pyometra in order to prevent morbidity. Material and Methods:, Retrospective study of 14 patients diagnosed between 1998 and 2008 with early-drainage pyometra and six patients with perforated pyometra were included. In addition, a review of the literature yielded another 30 perforated pyometra cases for comparison. Results:, Of 20 women with pyometra, the main presented symptoms at admission were abdominal pain (80%), fever (45%) and vaginal discharge (25%). The majority of organisms isolated were Bacteroides fragilis (seven cases), Streptococcus species (six cases) and Escherichia coli (five cases). Of the 36 cases with spontaneous uterine perforation to date, 35 cases (97%) had abdominal pain, 11 cases (31%) had fever, and 10 cases (27%) had vomiting. Hypoalbuminemia was found in seven patients (five cases in the perforation group and two cases in the drainage group). Conclusion:, Early diagnosis of pyometra before perforation can avoid surgical exploration and decrease morbidity and mortality. Perforated pyometra should be considered as a differential diagnosis in women with pneumoperitoneum and fever. Hypoalbuminemia should be considered as a predisposing factor for pyometra perforation.

    Identification and characterization of 20 immunocompetent patients with simultaneous varicella zoster and herpes simplex virus infection

    JOURNAL OF THE EUROPEAN ACADEMY OF DERMATOLOGY & VENEREOLOGY, Issue 6 2008
    KA Giehl
    Abstract Background, It has been shown that varicella zoster virus (VZV) and herpes simplex virus (HSV) can co-localize to the same sensory ganglion. However, only a few case reports on VZV/HSV co-infections exist. Objective,To identify and characterize patients with concurrent VZV and HSV infection at the same body site. Subjects/Methods, In 1718 patients, the presence of VZV and HSV in suspicious skin lesions was investigated by polymerase chain reaction analysis. Clinical characteristics of co-infected patients were compared with matched control patients infected with either VZV or HSV. The data are discussed in the context of an extensive review of the literature. Results, Twenty (1.2%) of 1718 patients were infected with both VZV and HSV at the same body site. The mean age was 54 years (range, 2,83). The clinical diagnosis was zoster in 65%, herpes simplex in 20%, varicella in 10% and erythema multiforme in 5% of cases. The trigeminus region was affected in 60% and the trunk in 25%. Involvement of the head was most commonly associated with a severe course of disease and with older age. Conclusion, Simultaneous VZV/HSV infection is rare but can occur in immunocompetent patients, which is often overlooked. The majority of cases is localized to the trigeminus region and affects elderly people. [source]


    Differences in clinical presentation of deep vein thrombosis in men and women

    JOURNAL OF THROMBOSIS AND HAEMOSTASIS, Issue 10 2008
    E. ROSEANN ANDREOU
    Summary.,Background:,As assessment of clinical pretest probability is the first step in the diagnostic evaluation of deep vein thrombosis (DVT), it is important to know if the clinical features of DVT are the same in men and women. Objectives:,To compare the prevalence and clinical characteristics of DVT, and the accuracy of clinical pretest probability assessment, between men and women with suspected DVT. Methods:,A retrospective analysis of individual patient data from three prospective studies by our group that evaluated diagnostic tests for a suspected first episode of DVT. Clinical characteristics, clinical pretest probability for DVT, and prevalence and extent of DVT was assessed in a total of 1838 outpatients. Results:,The overall prevalence of DVT was higher in men than in women (14.4% vs. 9.4%) (P = 0.001). The prevalence of DVT was higher in men than in women who were categorized as having a clinical pretest probability that was low (6.9% vs. 3.5%; P = 0.025) or moderate (16.9% vs. 8.7%; P = 0.04), but similar in patients in the high category (40.2% vs. 44.0%; P = 0.6). In patients diagnosed with DVT, swelling of the entire leg occurred more often (41.5% vs. 15.7%; P < 0.001), and thrombosis was more extensive (involvement of both popliteal and common femoral veins in 47.9% vs. 21.6%), in women than in men. Conclusions:,In outpatients with suspected DVT, the overall prevalence of thrombosis and the prevalence of thrombosis in those with a low or a moderate clinical pretest probability were higher in men than in women.
