Risk factors for lymph node metastasis in clinically node-negative penile cancer patients

INTERNATIONAL JOURNAL OF UROLOGY, Issue 4 2009
Aravind Ramkumar
Objectives: To analyze the effects of pathological T stage, grade, extent of surgery for primary tumor, and age group on the risk of developing lymph node metastasis in clinically node-negative penile cancer patients. Methods: We performed a retrospective analysis of 200 clinically node-negative penile cancer patients who were kept under surveillance, after treatment of the primary tumor in our institution. The primary outcome parameter was cytologically or histologically proven lymph node metastasis. Logistic regression analysis was used to compute odds ratios in univariate and multivariate settings. Results: Lymph node metastasis occurred in 31 patients at a median time of three months. Histological grade 3 and grade 2 tumors had a statistically significant increased odds ratio for lymph node metastasis, (7.1[P < 0.001] and 2.7 [P = 0.04], respectively), compared with grade 1 tumors. Although increasing pT stage was associated with increasing odds ratios, the differences were not statistically significant. Nor did the extent of surgery of the primary tumor or the age group significantly influence the risk of developing lymph node metastasis. Conclusions: Histological grade is the most significant parameter influencing the risk of lymph node metastasis in clinically node-negative penile cancer patients on surveillance. Patients with grade 3 and grade 2 tumors may benefit from elective inguinal lymphadenectomy. [source]


Too early to dismiss Yersinia enterocolitica infection in the aetiology of Graves' disease: evidence from a twin case,control study

CLINICAL ENDOCRINOLOGY, Issue 3 2008
Thomas H. Brix
Summary Background,Yersinia enterocolitica (YE) infection has long been implicated in the pathogenesis of Graves' disease (GD). The association between YE and GD could, however, also be due to common genetic or environmental factors affecting the development of both YE infection and GD. This potential confounding can be minimized by investigation of twin pairs discordant for GD. Aim, To examine whether YE infection is associated with GD. Design, We first conducted a classical case,control study of individuals with (61) and without (122) GD, and then a case,control study of twin pairs (36) discordant for GD. Methods, Immunoglobulin (Ig)A and IgG antibodies to virulence-associated Yersinia outer membrane proteins (YOPs) were measured. Main outcome measures, The prevalence of YOP IgA and IgG antibodies. Results, Subjects with GD had a higher prevalence of YOP IgA (49%vs. 34%, P = 0ˇ054) and YPO IgG (51%vs. 35%, P = 0ˇ043) than the external controls. The frequency of chronic YE infection, reflected by the presence of both IgA and IgG YOP antibodies, was also higher among cases than controls (49%vs. 33%, P = 0ˇ042). Similar results were found in twin pairs discordant for GD. In the case,control analysis, individuals with GD had an increased odds ratio (OR) of YE infection: IgA 1ˇ84 (95% CI 0ˇ99,3ˇ45) and IgG 1ˇ90 (95% CI 1ˇ02,3ˇ55). In the co-twin analysis, the twin with GD also had an increased OR of YE infection: IgA 5ˇ5 (95% CI 1ˇ21,24ˇ81) and IgG 5ˇ0 (95% CI 1ˇ10,22ˇ81). Conclusion, The finding of an association between GD and YE in the case,control study and within twin pairs discordant for GD supports the notion that YE infection plays an aetiological role in the occurrence of GD, or vice versa. Future studies should examine the temporal relationship of this association in more depth. [source]


How does the periapical inflammatory process compromise general health?

ENDODONTIC TOPICS, Issue 1 2004
Idikó.
Several lines of evidence support the causative role of oral inflammatory lesions and certain systemic diseases, such as atherosclerosis and cardiovascular diseases, adverse pregnancy outcome and lung diseases. Properly executed epidemiologic studies identified increased odds ratios. Local or metastatic spread of oral microorganisms, local production of microbial or host-derived soluble regulatory molecules, that may initiate or sustain inflammatory events in remote tissues and organs and the presence of (a) common , extrinsic- or intrinsic-pathological mechanism(s) may result in or contribute to both local and systemic inflammation. A number of cross-sectional studies addressing a possible association between oral health and systemic diseases have also investigated the presence or the absence of periapical lesions. However, these studies cannot either confirm or refute a role of the periapical inflammatory lesion in the observed associations, since other variables of oral health might have exerted an inestimable influence on general health of the assessed population. The literature, dealing with patients with root canal infections and apical periodontitis as sole oral inflammatory lesions is extremely sparse. Our group has demonstrated that young adults with apical periodontitis exhibit certain biochemical changes, such as elevated levels of C-reactive protein and an increased whole blood chemiluminescence, which have been shown to elevate the risk for cardiovascular diseases. Future research will be required to determine whether and to what extent may endodontic diseases affect general health. [source]


Probabilities of alcohol high-risk drinking, abuse or dependence estimated on grounds of tobacco smoking and nicotine dependence

ADDICTION, Issue 6 2003
Ulrich John
ABSTRACT Aims, To estimate probabilities of alcohol high-risk drinking, alcohol abuse and alcohol dependence on grounds of smoking-behaviour related variables and single nicotine dependence criteria. Design, Cross-sectional population-based study. Setting, Adult population of a region in north Germany. Participants, Cigarette smokers (n = 2437) among a random sample of 4075 females and males aged 18,64, drawn in 1996. Measurement, Smoking, nicotine dependence according to the Diagnostic and Statistical Manual of Psychiatric Disorders (DSM-IV) and the Fagerström Test for Nicotine Dependence (FTND); increasing alcohol-related harm (ARH): high-risk drinking, DSM-IV alcohol abuse, remitted and current alcohol dependence diagnosed by the Composite International Diagnostic Interview (CIDI). Findings, Having smoked 30 cigarettes or more per day, onset of smoking at the age of 17 or younger, nicotine dependence and single nicotine dependence criteria revealed odds ratios higher than 4.0 for alcohol dependence. For alcohol dependence, a logistic regression model showed an increased odds ratios for male gender, smoking for 25 years or more, no attempt to quit or cut down, continuation of smoking despite problems, craving for nicotine, withdrawal experience 1 day or longer, smoking first cigarette in the morning 5 minutes or less after waking. The probability of increasing ARH was more likely in males, smokers for 25 years or more, no attempt to quit or cut down, continuation of smoking despite problems and smoking first cigarette in the morning 5 minutes or less after waking. Conclusions, Gender and single nicotine dependence criteria show particularly high probabilities of alcohol dependence and increasing ARH. Interventions need to take these connections into account.
