Multiple pseudo-cellulitis plaques and Koplick's sign: a particular form of parvovirus B19 primo-infection in adults

INTRODUCTION: clinical presentation which seems to be more specific of this infection. EXEGESIS: A 35-year-old woman, 12 weeks pregnant, presented with a primary infection of parvovirus B19. The clinical presentation was characterized by pseudo-cellulitis plaques of the buttocks and the vulva, buccal enanthema with ulcerations and Koplick spot. CONCLUSION: This is the second observation which describes such cutaneous and mucosal manifestations associated with parvovirus B19 infection. This kind of clinical presentation should be systematically reported to become well known by the physicians as erythema infectiosum of fifth disease or "gloves and socks" syndrome.     

Care and prejudice: moving beyond mistrust in the care relationship with addicted patients

Social representations of addiction and the resulting stigmatization have been widely described and studied in the literature, but their effects are no less problematic. These representations, which also occur in care settings, generate a climate of distrust which damages the therapeutic relationship, and its ethical quality. This article, combining clinical experience and an ethical stance, offers an original, innovating approach to the existence of distrust in care relationships in the area of addiction. Pragmatic approaches deriving from the human sciences and analytical philosophy provide an invitation to escape from the demanding climate of mistrust, and to take the gamble on trust so as to improve the quality of interactions between protagonists in care. In complementary fashion, a sociology of action can combat the disquiet generated by distrust through a new commitment to innovating forms of action. This “poetic” mode of action is legitimized by the reflection that backs it up, and by its presentation to peers qualified to approve it. Finally, continental moral philosophy underlines the importance of a carefully weighed commitment on the part of caregivers and addicted patients towards promises aiming to support a sincere care relationship, without damaging the therapeutic dynamic or the ethical quality by providing too many safety nets. This reflection is intended to achieve better identification of the clinical and ethical issues raised by mistrust, and inclusion of these aspects in the training of personnel and in care provision planning.     

Diffuse soft tissue and vascular calcification in systemic lupus erythematosus with chronic kidney disease

The systemic disorder of mineral and bone metabolism which is related to chronic kidney disease (CKD) is called mineral and bone disorder (MBD). Calcifications related to CKD-MBD may occur in ophthalmic tissue, arterial walls, subcutaneous and periarticular soft tissues and organs. The vascular calcifications are the most important causes of mortality and morbidity in CKD. Here, we present a case of systemic lupus erythematosus with early and disseminated calcifications of vascular and periarticular soft tissues related to CKD-MBD.     

Role of penehyclidine in acute organophosphorus pesticide poisoning

BACKGROUND:Penehyclidine is a newly developed anticholinergic agent.We aimed to investigate the role of penehyclidine in acute organophosphorus pesticide poisoning(OP)patients.METHODS:We searched the Pubmed,Cochrane library,EMBASE,Chinese National Knowledge Infrastructure(CNKI),Chinese Biomedical literature(CBM)and Wanfang databases.Randomized controlled trials(RCTs)recruiting acute OP patients were identifi ed for meta-analysis.Main outcomes included cure rate,mortality rate,time to atropinization,time to 60%normal acetylcholinesterase(AchE)level,rate of intermediate syndrome(IMS)and rate of adverse drug reactions(ADR).RESULTS:Sixteen RCTs involving 1,334 patients were identifi ed.Compared with the atropineor penehyclidine-alone groups,atropine combined with penehyclidine significantly increased the cure rate(penehyclidine+atropine vs.atropine,0.97 vs.0.86,RR 1.13,95%CI[1.07–1.19];penehyclidine+atropine vs.penehyclidine,0.93 vs.0.80,RR 1.08,95%CI[1.01–1.15])and reduced the mortality rate(penehyclidine+atropine vs.atropine,0.015 vs.0.11,RR 0.17,95%CI[0.06–0.49];penehyclidine+atropine vs.penehyclidine,0.13 vs.0.08,RR 0.23,95%CI[0.04–1.28]).Atropine combined with penehyclidine in OP patients also helped reduce the time to atropinization and AchE recovery,the rate of IMS and the rate of ADR.Compared with a single dose of atropine,a single dose of penehyclidine also signifi cantly elevated the cure rate,reduced times to atropinization,AchE recovery,and rate of IMS.CONCLUSION:Atropine combined with penehyclidine benefi ts OP patients by enhancing the cure rate,mortality rate,time to atropinization,AchE recovery,IMS rate,total ADR and duration of hospitalization.Penehyclidine combined with atropine is likely a better initial therapy for OP patients than atropine alone.     

Consensus‐based European guidelines for treatment of atopic eczema (atopic dermatitis) in adults and children: part I

This guideline was developed as a joint interdisciplinary European project, including physicians from all relevant disciplines as well as patients. It is a consensus‐based guideline, taking available evidence from other guidelines, systematic reviews and published studies into account. This first part of the guideline covers methods, patient perspective, general measures and avoidance strategies, basic emollient treatment and bathing, dietary intervention, topical anti‐inflammatory therapy, phototherapy and antipruritic therapy, whereas the second part covers antimicrobial therapy, systemic treatment, allergen‐specific immunotherapy, complementary medicine, psychosomatic counselling and educational interventions. Management of AE must consider the individual clinical variability of the disease; highly standardized treatment rules are not recommended. Basic therapy is focused on treatment of disturbed barrier function by hydrating and lubricating topical treatment, besides further avoidance of specific and unspecific provocation factors. Topical anti‐inflammatory treatment based on glucocorticosteroids and calcineurin inhibitors is used for flare management and for proactive therapy for long‐term control. Topical corticosteroids remain the mainstay of therapy, whereas tacrolimus and pimecrolimus are preferred in sensitive skin areas and for long‐term use. Topical phosphodiesterase inhibitors may be a treatment alternative when available. Adjuvant therapy includes UV irradiation, preferably with UVB 311 nm or UVA1. Pruritus is targeted with the majority of the recommended therapies, but some patients may need additional antipruritic therapy. Antimicrobial therapy, systemic anti‐inflammatory treatment, immunotherapy, complementary medicine and educational intervention will be addressed in part II of the guideline.     

Predicting Factors for Mortality in the Penetrating Abdominal Trauma

Purpose: penetrating abdominal trauma (PAT) is still a serious problem all over the world. This study was made to define and discuss the factors that could affect mortality in the PAT.

Methods: the records of 1048 patients hospitalized and operated for PAT at Dicle University Hospital (DUH) between January 1990 and December 2001 were retrospectively reviewed. Patients (n = 1048) were divided into two groups: “Healthy Group” (HG) (n = 942) and “Deathly Group” (DG) (n = 106). The epidemiological and clinical features were evaluated as probable risk factors for mortality. The risk factors for mortality were revealed using univariate and multi-variate analyses.

Results: a total of 1048 patients [937 (89.4%) male, 111(10.6%) female] with PAT were included in this study. The mortality rate (22.5%) of female patients was significantly higher than (8.6%) that of male patients (p = 0.000). The mean age was 30.01 ± 63.9 (14–74) years and 30 ± 12.5(15–71) years in the HG and DG consecutively (p = 0.85). The average interval between injury and operation (IBIO) was 2.09 ±1.3 (0.5–3) and 6.9 ±11.4 (1–6.1) hours in the HG and DG respectively (p = 0.000). Presence of shock on admission (PSDA) was determined in 87 patients and in 96 patients in the HG and DG respectively (p = 0.000). The mortality rate (14.9%) in patients presenting gunshot wounds (GSW) was significantly higher than (2.7%) that of patients with stab wounds (SW) (p = 0.000). The average number of injured intraabdominal organs (NIAOI) was 1.98 ±1.08 (1–7) and 4.67 ±1.99 (1-13) in the HG and DG respectively (p = 0.000). Mortality rates were 72.7% in cardiac injury, 30% in great vessels injuries, 32.6% in cranial injury, and 21.5% in major extremity and pelvic injury (p = 0.000). The average penetrating abdominal trauma index (PATI) was 11.78 ± 9.44 (158) and 46.24 ± 22.18 (15-119) in the HG and DG respectively (p = 0.000).

In multivariate analyses, female gender [Odds Ratio (OR) = 10.74, 95% Confidence Interval (CI) = 3.03–38.12, P = 0.000], the long IBIO (OR = 1.82, CI = 1.39–2.40, P = 0.000), PSDA (OR = 94.45, CI = 28.32–314.95, P = 0.000), presence of cranial injury (OR = 0.03, CI = 0.002–0.363, P = 0.006) and high PATI (OR = 1.14, CI = 1.09–1.19, P = 0.000), were found significantly important for mortality.

Conclusion: we determined that conditions such as, female gender, long interval between injury and operation, presence of shock on admission, presence of cranial injury and high PATI were predicting factors for mortality in PAT.     

Effects of current and potential dental etchants on nerve compound action potentials

In this study, a 35% phosphoric acid gel (3M Scotchbond etchant), a nonrinse etchant (NRC), and two EDTA-containing conditioners (RC-Prep and File-Eze) were tested in vitro for blocking nerve conductance evoked in the rat sciatic nerve after local application. The phosphoric acid gel and NRC completely and irreversibly inhibited conductance. On the other hand, RC-Prep reduced the compound action potentials (cAPs) by 50% in 120 min. With File-Eze, the reduction in cAPs was less than 50% after an application time of 160 min (61.8 +/- 1.8%). At 160 min the cAPs in the RC-Prep group had been inhibited by 62.4%. These results indicated strong neurotoxic effects of phosphoric acid and NRC when applied directly on exposed pulp in the total etch procedure.
