Low-dose cidofovir for the treatment of polyomavirus-associated nephropathy: two case reports and review of the literature.

BACKGROUND: Polyomavirus-associated nephropathy (PVAN) is a serious complication and cause of graft loss in kidney transplant recipients. In the absence of specific antiviral drugs, early detection of the disease and reduction of immunosuppressive regimen is the cornerstone of therapy. Cidofovir, a nucleoside analogue, has been found to inhibit BK virus (BKV) replication in vitro and has been proposed as treatment of refractory PVAN at low doses; however, its efficacy has never been demonstrated in randomized controlled trials. METHODS: Cidofovir therapy (0.5 mg/kg at a 2-week interval for eight consecutive doses) was initiated in two patients with biopsy-proven PVAN and persistent BKV DNA viraemia (> or = 10,000 copies/ml despite sustained reduction of the immunosuppressive regimen). In addition to these two case reports, we performed a critical review of the literature on the use of cidofovir in PVAN. RESULTS: No significant decrease of BKV viral load in blood was observed during cidofovir therapy and in follow-up of the two patients treated with cidofovir. Our literature review identified 21 publications reporting the use of cidofovir for the treatment of PVAN. All were case reports or small series. The efficacy of cidofovir therapy could not be assessed in 17 of these publications because of lack of data or concomitant reduction of immunosuppressive regimen. The four remaining publications were case reports. CONCLUSIONS: In vitro and clinical data to support the efficacy of cidofovir in the treatment of PVAN are currently lacking. More promising compounds should be identified for further clinical studies.

French version of the Family Attitude Scale: Psychometric properties and relation of attitudes to the respondent's psychiatric status.

The Family Attitude Scale (FAS) is a self-report measure of critical or hostile attitudes and behaviors towards another family member, and demonstrates an ability to predict relapse in psychoses. Data are not currently available on a French version of the scale. The present study developed a French version of the FAS, using a large general population sample to test its internal structure, criterion validity and relationships with the respondents' symptoms and psychiatric diagnoses, and examined the reciprocity of FAS ratings by respondents and their partners. A total of 2072 adults from an urban population undertook a diagnostic interview and completed self-report measures, including an FAS about their partner. A subset of participants had partners who also completed the FAS. Confirmatory factor analyses revealed an excellent fit by a single-factor model, and the FAS demonstrated a strong association with dyadic adjustment. FAS scores of respondents were affected by their anxiety levels and mood, alcohol and anxiety diagnoses, and moderate reciprocity of attitudes and behaviors between the partners was seen. The French version of the FAS has similarly strong psychometric properties to the original English version. Future research should assess the ability of the French FAS to predict relapse of psychiatric disorders.

Acquisitions de la littérature en médecine interne générale ambulatoire en 2010 [2010 findings from literature on general internal ambulatory medicine].

From our reading over the current year 2010 we have singled out 8 items which seem to us significant for the practice of medicine. Small doses of colchicine are useful in the treatment of gout. No efficacious treatment for muscular cramps can be recommended. A cervical collar can be usefully prescribed for the treatment of cervical radiculopathy. A single dose of azithromycin can be envisaged as a third line treatment of syphilis. High doses of vitamin D should not be prescribed for the prevention of fractures in elderly women because of the risks of falling. The wearing of bifocals can be associated with these risks. A clinical score is available to help with the diagnosis of thoracic pain. The NT-pro BNP is of limited use for the follow-up of patients suffering from heart failure.

Cultured epithelial autografts in the management of burn injuries: a review of the literature

Introduction. The management of large burn victims has significantly improved in the last decades. Specifically autologous cultured keratinocytes (CEA) overcame the problem of limited donor sites in severely burned patients. Several studies testing CEA's in their burn centers give mixed results on the general outcomes of burn patients. Methods. A review of publications with a minimum of 15 patients per study using CEA for the management of severe burn injury from 1989 until 2011 were recruited by using an online database including Medline, Pub Med and the archives of the medical library of the CHUV in Lausanne. Results. 18 studies with a total of 977 patients were included into this review. Most of the studies did not specify if CEA's were grafted alone or in combination with split thickness skin grafts (STSG) although most of the patients seemed to have received both methodologies in reviewed studies. The mean TBSA per study ranged from 33% to 78% in patients that were grafted with CEA's. Here no common minimum TBSA making a patient eligible for CEA grafting could be found. The definition of the "take rate" is not standardized and varied largely from 26% to 73%. Mortality and hospitalization time could not be shown to correlate with CEA use in all of the studies. As late complications, some authors described the fragility of the CEA regenerated skin. Conclusion. Since the healing of large burn victims demands for a variety of different surgical and non-surgical treatment strategies and the final outcome mainly depends on the burned surface as well as the general health condition of the patient, no definitive conclusion could be drawn from the use of CEA's of reviewed studies. From our own experience, we know that selected patients significantly profit from CEA grafts although cost efficiency or the reduction of mortality cannot be demonstrated on this particular cases.

Etude de validation d'une version francophone du Q-Sort d'attachement de Waters et Deane = A validation study of the french adaptation of Waters and Deane's attachment Q-sort

Ce texte relate l'étude de validation d'une adaptation francophone du Q-Sort d'attachement de Waters et Deane (cette adaptation est présentée dans ce même numéro). Le Q-Sort rempli par les parents ne paraît pas tenir ses promesses de méthode alternative à la Situation étrange pour évaluer la qualité de la relation d'attachement. Cependant, lorsqu'il est rempli par un observateur extérieur, il semble mieux refléter la catégorisation des comportements dans la Situation étrange. Au travers du Q-Sort, les parents semblent décrire davantage le tempérament de l'enfant que la qualité de la relation d'attachement.

EZ-IO(®) intraosseous device implementation in a pre-hospital emergency service: A prospective study and review of the literature.

INTRODUCTION: Intraosseous access is increasingly recognised as an effective alternative vascular access to peripheral venous access. We aimed to prospectively study the patients receiving prehospital intraosseous access with the EZ-IO(®), and to compare our results with those of the available literature. METHODS: Every patient who required an intraosseous access with the EZ-IO from January 1st, 2009 to December 31st, 2011 was included. The main data collected were: age, sex, indication for intraosseous access, localisation of insertion, success rate, drugs and fluids administered, and complications. All published studies concerning the EZ-IO device were systematically searched and reviewed for comparison. RESULTS: Fifty-eight patients representing 60 EZ-IO procedures were included. Mean age was 47 years (range 0.5-91), and the success rate was 90%. The main indications were cardiorespiratory arrest (74%), major trauma (12%), and shock (5%). The anterior tibia was the main route. The main drugs administered were adrenaline (epinephrine), atropine and amiodarone. No complications were reported. We identified 30 heterogeneous studies representing 1603 EZ-IO insertions. The patients' characteristics and success rate were similar to our study. Complications were reported in 13 cases (1.3%). CONCLUSION: The EZ-IO provides an effective way to achieve vascular access in the pre-hospital setting. Our results were similar to the cumulative results of all studies involving the use of the EZ-IO, and that can be used for comparison for further studies.

Equivalence of paper and pencil vs internet forms of the ZKPQ-50-CC in Spanish and French samples

This study was designed to check for the equivalence of the ZKPQ-50-CC (Spanish and French versions) through Internet on-line (OL) and paper and pencil (PP) answer format. Differences in means and devia- tions were significant in some scales, but effect sizes are minimal except for Sociability in the Spanish sample. Alpha reliabilities are also very similar in both versions with no significant differences between formats. A robust factorial structure was found for the two formats and the average congruency coefficients were 0.98. The goodness-of-fit indexes obtained by confirmatory factorial analysis are very similar to those obtained in the ZKPQ-50-CC validation study and they do not differ between the two formats. The multi-group analysis confirms the equivalence among the OL-PP formats in both countries. These results in general support the validity and reliability of the Internet as a method in investigations using the ZKPQ-50-CC.

Literature and Mythology in Tennessee Williams's "Suddenly Last Summer": Fighting against Venus and Oedipus

The aim of this article is to analyze accurately the role played by two classical references, Venus and Oedipus, in Tennessee Williams Suddenly Last Summer, in accordance with the usual nature of studies on Classical Tradition a Greek and Roman- and focusing in this case on the relationship between literature and mythology. It is thanks to Venus and Oedipus that the playwright succeeds in showing the magnitude of mens and womens tragedy, which from his point of view is simply that they have failed to see either kindness in the face of God or to feel his loving and fatherly providence.

Epibulbar osseous choristoma: a clinicopathological case series and review of the literature [Epibulbäre knöcherne Choristome: eine klinisch-pathologische Fallserie und Überblick der Literatur]

BACKGROUND: Choristomas are benign, congenital tumours composed of normal tissue in an abnormal location. Osseous choristomas represent the rarest form of epibulbar choristomas, with now 65 cases reported in the literature. We did a retrospective clinicopathological study of all patients with epibulbar osseous choristoma observed at our institution since 1982 and updated the last review of the literature. HISTORY AND SIGNS: Three Caucasian male patients, aged between 3 months and 11 years, were identified. All osseous choristomas were located under the superotemporal bulbar conjunctiva of the right eye. THERAPY AND OUTCOME: All lesions were managed with surgical excision. Histopathology revealed the presence of lamellar bone in all cases, one of which was associated with a dermolipoma. CONCLUSIONS: We report a small rare case series of 3 epibulbar osseous choristomas and did a review of the literature. In one patient, the osteoma was associated with a dermolipoma, corresponding to the fourth reported complex choristoma of this type, in an otherwise normal eye, in the literature.

Congenital diaphragmatic hernia: current status and review of the literature.

Treatment of congenital diaphragmatic hernia (CDH) challenges obstetricians, pediatric surgeons, and neonatologists. Persistent pulmonary hypertension (PPHT) associated with lung hypoplasia in CDH leads to a high mortality rate at birth. PPHT is principally due to an increased muscularization of the arterioles. Management of CDH has been greatly improved by the introduction of prenatal surgical intervention with tracheal obstruction (TO) and by more appropriate postnatal care. TO appears to accelerate fetal lung growth and to increase the number of capillary vessels and alveoli. Improvement of postnatal care over the last years is mainly due to the avoidance of lung injury by applying low peak inflation pressure during ventilation. The benefits of other drugs or technical improvements such as the use of inhaled nitric oxide or extracorporeal membrane oxygenation (ECMO) are still being debated and no single strategy is accepted worldwide. Despite intensive clinical and experimental research, the treatment of newborn with CDH remains difficult.
