Acute retinal necrosis in primary herpes simplex virus type I infection.

Here we report the case of an immunocompetent 8-year-old child who developed acute retinal necrosis concomitant with a primary herpes simplex virus type I infection. Ocular inflammation changed along with the development of a specific antibody titer in the serum. This evidence suggests that the immune response of the host can significantly modulate the clinical aspect of the ocular infection.

Sexueller Missbrauch bei Kindern und Jugendlichen- Aufdeckung, Untersuchung und Erstbetreuung [Sexual abuse of female children and adolescents--detection, examination and primary care].

Epidemiological studies show a prevalence of sexual abuse experience among girls from 14-33%. Although indicators of abuse are unspecific, the combination of several findings may be indicative: Somatic signs may be sexually transmitted diseases, vulvovaginal complaints. Psychosocial nonsexual indicators are abrupt behavioural changes, running away from home, eating disorders. Psychosexual signs are hypersexualisation of the language and behaviour, disturbed body image and gender identity. Indirect evidence of abuse is given not only in cases of old vaginal and anal lesions but also in situations, where deep tears of the hymen in the typical localization at the posterior part can be found. The workup and care for children in whom there is suspicion of abuse but no clear evidence asks for highly competent professionals in a multidisciplinary cooperation including pediatric gynecologists, child psychiatrists, children-protection groups and other specialists to avoid on one hand unjustified destabilisation or even destruction of familial structures but to assure on the other hand, that the child victims are treated and followed after in a short and long term comprehensive medical and psychosocial care.

Cyclooxygenase-2 in human and experimental ischemic proliferative retinopathy.

BACKGROUND: Intravitreal neovascular diseases, as in ischemic retinopathies, are a major cause of blindness. Because inflammatory mechanisms influence vitreal neovascularization and cyclooxygenase (COX)-2 promotes tumor angiogenesis, we investigated the role of COX-2 in ischemic proliferative retinopathy. METHODS AND RESULTS: We describe here that COX-2 is induced in retinal astrocytes in human diabetic retinopathy, in the murine and rat model of ischemic proliferative retinopathy in vivo, and in hypoxic astrocytes in vitro. Specific COX-2 but not COX-1 inhibitors prevented intravitreal neovascularization, whereas prostaglandin E2, mainly via its prostaglandin E receptor 3 (EP3), exacerbated neovascularization. COX-2 inhibition induced an upregulation of thrombospondin-1 and its CD36 receptor, consistent with the observed antiangiogenic effects of COX-2 inhibition; EP3 stimulation reversed effects of COX-2 inhibitors on thrombospondin-1 and CD36. CONCLUSIONS: These findings point to an important role for COX-2 in ischemic proliferative retinopathy, as in diabetes.

Primary testicular lymphoma: review

Primary testicular lymphoma is a rare form of non-Hodgkin's lymphoma. It occurs more frequently in older patients, and it is a potentially lethal disease. For early stages (I and II), the management consists of orchidectomy followed by chemotherapy combined with monoclonal antibodies directed against the CD20 antigen and scrotal radiotherapy (sanctuary site) with/or without iliac and/or paraaortic lymph node radiotherapy. For advanced stages (III and IV), chemo-immunotherapy is the treatment of choice while scrotal radiotherapy can be discussed. Both in early or advanced disease, intrathecal chemotherapy is necessary to prevent central nervous system relapse. New molecular approaches and/or more aggressive treatments are to be explored in this rare disease. To cite this journal: Oncologie 13 (2011).

Increased neuroendocrine cells in resected metastases compared to primary colorectal adenocarcinomas.

Neuroendocrine differentiation has been described in rectal adenocarcinomas receiving neoadjuvant therapy prior to radical surgery, but its clinical relevance is controversial and no data are currently available in colorectal carcinoma metastases as compared to primary tumors. The presence of chromogranin A positive tumor cells was investigated by means of immunohistochemistry on surgical specimens from 54 primary colorectal carcinomas and their corresponding metastases, resected at diagnosis or during tumor progression. In 47 patients, tumor metastases were resected 1 month to 12 years after chemotherapy and/or radiotherapy, while in the remaining seven patients no additional therapy after primary surgery was performed. In primary tumors, neuroendocrine differentiation was found in 12/54 cases (22.2%) as compared to 25/54 metastatic lesions (46.3%; p?=?0.01). The presence of neuroendocrine phenotype was not correlated with any clinical pathological parameter nor with a different proliferation index. However, patients having neuroendocrine cells in the primary tumor had a significantly shorter survival from the time of metastatic spread than those having not (33.3 vs. 55.5 months; p?=?0.04). In summary, our data show that colorectal carcinoma metastases contain a higher percentage of neuroendocrine differentiated cells as compared to their corresponding primaries, a finding possibly related to the influence of chemotherapy in neuroendocrine differentiation during colorectal carcinoma progression.

Increased expression of urokinase-type plasminogen activator mRNA determines adverse prognosis in ErbB2-positive primary breast cancer.

PURPOSE: To evaluate and validate mRNA expression markers capable of identifying patients with ErbB2-positive breast cancer associated with distant metastasis and reduced survival. PATIENTS AND METHODS: Expression of 60 genes involved in breast cancer biology was assessed by quantitative real-time PCR (qrt-PCR) in 317 primary breast cancer patients and correlated with clinical outcome data. Results were validated subsequently using two previously published and publicly available microarray data sets with different patient populations comprising 295 and 286 breast cancer samples, respectively. RESULTS: Of the 60 genes measured by qrt-PCR, urokinase-type plasminogen activator (uPA or PLAU) mRNA expression was the most significant marker associated with distant metastasis-free survival (MFS) by univariate Cox analysis in patients with ErbB2-positive tumors and an independent factor in multivariate analysis. Subsequent validation in two microarray data sets confirmed the prognostic value of uPA in ErbB2-positive tumors by both univariate and multivariate analysis. uPA mRNA expression was not significantly associated with MFS in ErbB2-negative tumors. Kaplan-Meier analysis showed in all three study populations that patients with ErbB2-positive/uPA-positive tumors exhibited significantly reduced MFS (hazard ratios [HR], 4.3; 95% CI, 1.6 to 11.8; HR, 2.7; 95% CI, 1.2 to 6.2; and, HR, 2.8; 95% CI, 1.1 to 7.1; all P < .02) as compared with the group with ErbB2-positive/uPA-negative tumors who exhibited similar outcome to those with ErbB2-negative tumors, irrespective of uPA status. CONCLUSION: After evaluation of 898 breast cancer patients, uPA mRNA expression emerged as a powerful prognostic indicator in ErbB2-positive tumors. These results were consistent among three independent study populations assayed by different techniques, including qrt-PCR and two microarray platforms.

Incontinence urinaire chez la femme: prise en charge en médecine de premier recours [Urinary incontinence in women: management in primary care]

Urinary incontinence in women is a largely under-evaluated problem that affects nearly one out of two adult women. Even thouh its physiopathology is complex and its etiologies are multiple (and often intricate), urodynamic investigations are not considered necessary before starting a conservative therapy, which can be initiated by the primary care physician. Conservative management is based upon lifestyle modifications, specialized physiotherapy, and in certain cases medication. In the case of insufficient response after three months, the patient should be recommended to a specialist who can evaluate the need for a surgical procedure.

Prévention primaire et dépistage chez l'adulte: mise a jour 2014 [Primary prevention and screening in adults: update 2014].

Cet article propose une mise à jour des recommandations pour le bilan de santé et la prévention primaire et secondaire de nombreuses maladies cardiovasculaires et oncologiques. Les nouveautés pour le dépistage des cancers concernent essentiellement les cancers colorectal, du poumon et de la prostate. Pour la prévention des maladies cardiovasculaires, le dépistage de la sténose de l'artère carotidienne n'est toujours pas recommandé. Les preuves de la littérature sont insuffisantes pour recommander le dépistage de l'artériopathie coronarienne ou périphérique chez les patients asymptomatiques. Le partage de l'information et de la décision entre le médecin et le patient est à privilégier lorsqu'il existe une incertitude quant à l'efficacité d'une intervention. This article provides an update on the recommendations for the routine check-up and the primary and secondary prevention of cancer and cardiovascular disease. Changes for cancer screening affect mainly colorectal, lung and prostate cancers. In the area of cardiovascular disease prevention, screening for carotid artery stenosis is still not recommended. The current evidence is insufficient to recommend screening for coronary heart disease or peripheral artery disease in asymptomatic patients. Shared information and decision making between physician and patient is recommended when there is uncertainty regarding the effectiveness of an intervention.

Cost-effectiveness of pharmacotherapies for nicotine dependence in primary care settings: a multinational comparison.

OBJECTIVE: To estimate the incremental cost-effectiveness of the first-line pharmacotherapies (nicotine gum, patch, spray, inhaler, and bupropion) for smoking cessation across six Western countries-Canada, France, Spain, Switzerland, the United States, and the United Kingdom. DESIGN AND STUDY POPULATION: A Markov-chain cohort model to simulate two cohorts of smokers: (1) a reference cohort given brief cessation counselling by a general practitioner (GP); (2) a treatment cohort given counselling plus pharmacotherapy. Effectiveness expressed as odds ratios for quitting associated with pharmacotherapies. Costs based on the additional physician time required and retail prices of the medications. INTERVENTIONS: Addition of each first-line pharmacotherapy to GP cessation counselling. MAIN OUTCOME MEASURES: Cost per life-year saved associated with pharmacotherapies. RESULTS: The cost per life-year saved for counselling only ranged from US190 dollars in Spain to 773 dollars in the UK for men, and from 288 dollars in Spain to 1168 dollars in the UK for women. The incremental cost per life-year saved for gum ranged from 2230 dollars for men in Spain to 7643 dollars for women in the US; for patch from 1758 dollars for men in Spain to 5131 dollars for women in the UK; for spray from 1935 dollars for men in Spain to 7969 dollars for women in the US; for inhaler from 3480 dollars for men in Switzerland to 8700 dollars for women in France; and for bupropion from 792 dollars for men in Canada to 2922 dollars for women in the US. In sensitivity analysis, changes in discount rate, treatment effectiveness, and natural quit rate had the strongest influences on cost-effectiveness. CONCLUSIONS: The cost-effectiveness of the pharmacotherapies varied significantly across the six study countries, however, in each case, the results would be considered favourable as compared to other common preventive pharmacotherapies.

Metastatic primary adenocarcinoma of the bladder in a twenty-five years old woman.

Primary adenocarcinoma of the bladder is a rare tumor. The classification between primary vesical and urachal is debated. We present the case of a young female who presented clinicopathological features of a metastatic urachal adenocarcinoma, but the histological result revealed primary adenocarcinoma of the bladder contrary to expectancy. To the best of our knowledge this is the first reported case of a metastatic adenocarcinoma of the bladder in a 25 years old female. This case emphasizes the challenge for urologists to recognize and manage this aggressive tumor in the setting described.

Occult lung infarction may induce false interpretation of 18F-FDG PET in primary staging of pulmonary malignancies.

PURPOSE: The aim of the present report is to describe abnormal (18)F-fluorodeoxyglucose (FDG) accumulation patterns in the pleura and lung parenchyma in a group of lung cancer patients in whom lung infarction was present at the time of positron emission tomography (PET). METHODS: Between November 2002 and December 2003, a total of 145 patients (102 males, 43 females; age range 38-85 years) were subjected to whole-body FDG PET for initial staging (n=117) or restaging (n=11) of lung cancer or for evaluation of solitary pulmonary nodules (n=17). Of these patients, 24 displayed abnormal FDG accumulation in the lung parenchyma that was not consistent with the primary lesion under investigation (ipsilateral n=12, contralateral n=9 or bilateral n=3). Without correlative imaging, this additional FDG uptake would have been considered indeterminate in differential diagnosis. RESULTS: Of the 24 patients who were identified as having such lesions, six harboured secondary tumour nodules diagnosed as metastases, while in three the diagnosis of a synchronous second primary lung tumour was established. Additionally, nine patients were identified as having post-stenotic pneumonia and/or atelectasis (n=6) or granulomatous lung disease (n=3). In the remaining six (4% of all patients), a diagnosis of recent pulmonary embolism that topographically matched the additional FDG accumulation (SUV(max) range 1.4-8.6, mean 3.9) was made. Four of these six patients were known to have pulmonary embolism, and hence false positive interpretation was avoided by correlating the PET findings with those of the pre-existing diagnostic work-up. The remaining two patients were harbouring small occult infarctions that mimicked satellite nodules in the lung periphery. Based on histopathological results, the abnormal FDG accumulation in these two patients was attributed to the inflammatory reaction and tissue repair associated with the pathological cascade of pulmonary embolism. CONCLUSION: In patients with pulmonary malignancies, synchronous lung infarction may induce pathological FDG accumulation that can mimic active tumour manifestations. Identifying this potential pitfall may allow avoidance of false positive FDG PET interpretation.

Reoperative Roux-En-Y Gastric Bypass Provides Similar Long-Term Results as Primary Surgery

Background: The increasing prevalence of obesity worldwide is associated with a massive increase in the number of yearly performed bariatric procedures, many of them purely restrictive. Consequently, a growing number of surgical revisions are necessary, and conversion to Roux-en-Y gastric bypass (RYGBP) is a common option. So far, few series including mostly patients reoperated using open surgery,and limited follow-up, have been reported.Patients and methods: Retrospective analysis of prospectively collected data of all patients undergoing revisional RYGBP in our two departments.Results: Between June 1999 and February 2011, 186 patients were submitted to revisional RYGBP, 161 women and 25 men with a mean age of 43 years. Their mean initial BMI was 45,3 kg/m2, their mean nadir BMI between the index operation and revision was 34, and their mean pre-revision BMI was 38,5. The initial procedure was gastric banding in 134 (72 %) patients, VBG in 48 (25,8 %), RYGBP in 5 (2,7 %), and others in 3. The main indications for revision were complications from the primary procedure with or without weight regain. A laparoscopic approach was usedin 137 (73,7 %) cases. Overall early morbidity was 18,8 %, and major morbidity was 3,2 %. Comparing patients in the first, second and last third of our experience, the percentage of patients operated using a laparoscopic approach increased from 53,2 % to 71 % and finally 96,7 %, and overall morbidity decreased from 27,4 % to 24,2 % and then 4,8 %. There were more wound infections after laparotomy (22,4 versus 2,9 %, p<0,001). There was no mortality. The mean BMI remained between 30 and 32 up to nine years after revision. Up to this limit, a BMI of <35 was maintained in between 75 and 83 % of the patients.Conclusions: Revisional RYGBP proves to be an effective and safe procedure. It can be performed by laparoscopy in most cases, especially as experience increases., It is associated with an acceptable morbidity, though higher than with primary RYGBP. Long-term results are equivalent to those of primary RYGBP, and can be considered as very satisfactory considering the fact that, on average, patients requiring redo surgery represent a sub-selection of difficult bariatric patients.

Hypertension artérielle pulmonaire primitive et maladie de Basedow [Primary pulmonary hypertension arterial and Basedow disease].

We report a case of a fifty year old woman with Graves' disease with positive AntiTPO antibodies and positive AntiTSH receptor antibodies, who was hospitalized with a right cardiac failure. A pulmonary hypertension was discovered on echocardiography. After adequate antithyroid therapy, the right cardiac failure regressed rapidly and pulmonary pressure normalised. An autoimmune process has often been proposed to explain the association between pulmonary hypertension and hyperthyroidism. We report the arguments supporting this autoimmune etiopathogenesis. We also discuss an other hypothesis based on a direct effect of thyroid hormones on the pulmonary circulation and the effects of high cardiac output associated with hyperthyroidism.
