Cerebrovascular accidents in infective endocarditis: role of anticoagulation

Anticoagulation is still a matter of debate in infective endocarditis,since it can increase the risk of complications, mostly neurological.In our series of 269 patients with native valve endocarditisstudied between 1970 and 1982, 35 were anticoagulated. We observed14 patients with brain infarcts, of whom five died, and 12 patientswith cerebromeningeal or brain haemorrhage of whom six died.In a similar series of 63 patients with prosthetic valve endocarditis,all of whom were on anticoagulation and were studied between1972 and 1987, we observed five patients with brain infarcts,three of whom died, and two patients with brain haemorrhage,one of whom died. The frequency of cerebrovascular accident(CVA) was similar for both groups (111% in prosthetic endocarditisvs 11.5% in native valve endocarditis, P = ns), as was mortalityrate (57% vs 48–4%, P = ns). CVA are significantly morefrequent among anticoagulated patients (19/94 vs 19/238: P<0.01),but the mortality rate in CVA is similar for anticoagulatedand non-ant icoagulated patients (11/19 vs 8/19: P = ns). Theindications for anticoagulation in infective endocarditis remainsimilar to those in valvular heart disease. In patients withinfective endocarditis, anticoagulation with heparin shouldbe maintained whenever a brain infarct is present, unless itis large and/or haemorrhagic.     

Free deep inferior epigastric artery perforator flap for reconstruction of soft‐tissue defects in extremities of children

The deep inferior epigastric artery perforator (DIEP) flap has been a valuable tool in breast reconstruction, but seldom in extremity reconstruction. The aim of this report is to present our experience on the use of the DIEP flap for reconstruction of soft‐tissue defects in the extremities of pediatric patients. From January 2007 to February 2011, 22 consecutive free DIEP flap transfers were performed for reconstruction of complex soft‐tissue defects in the extremities of children with a mean age of 5.7 years old (ranging 2–10 years old). The flap design included transverse, oblique, and irregular DIEP flaps, containing one to three perforators in the flap. The flap size ranged from 7 × 4 cm to 18 × 17 cm. Primary donor‐site closure was accomplished in all of patients. The postoperative course was uneventfully in most of cases. The venous congestion was observed in two cases. One case of venous congestion was caused by flap inset with tension. The other case with venous thrombosis ended with partial loss of the flap after salvage procedure. There was one total flap loss due to the arterial thrombosis. The flap survival rate was 95.5%. The mean follow‐up was 12 months (ranging 6–36 months). All reconstructed extremities had satisfactory aesthetic and functional outcomes except two cases undergoing the secondary debulking procedures. The donor sites healed well in all cases without complications. Our experience showed that the free DIEP flap could be an alternative for reconstruction of soft‐tissue defects in the extremities of children. © 2013 Wiley Periodicals, Inc.

Vacuum assisted closure therapy for treatment of complex wounds in replanted extremities

The object of this study was to compare the outcomes of the vacuum assisted closure (VAC) therapy and conventional wound care with dressing change for treatment of complex wounds in patients with replantation of amputated upper and lower extremities. Data of 43 patients with replantation of amputated extremities from May 2004 to December 2011 were reviewed. There were 18 wounds of 18 patients with replantation, which were treated by dressing change and 26 wounds of 25 patients by VAC therapy. The outcomes were evaluated by the survival rate of replanted extremities, growth of granulation tissue, interval between wound treatment and secondary procedure and eventual secondary wound coverage methods. Vascular thromboses were found in 3 patients with wound treatment by dressing change and 5 by VAC. All replants of two groups of patients survived after salvage procedures. The wound score was 3.6 ± 0.7 in the conventional dressing change group and 5.8 ± 0.7 in the VAC group at the sixth day after treatment, respectively. The intervals between wound treatment and secondary wound coverage procedure were 12.0 ± 1.7 days in the dressing change group and 6.1 ± 0.7 days in the VAC group. Flaps were applied for wound coverage in 9 out of 18 (50.0%) wounds in the dressing change group and 5 out of 26 (19.2%) in the VAC group (P < 0.05), when the wounds of rest of patients were covered by the skin graft. The results showed that VAC could promote the growth of granulation tissue of wound, decrease the need of flap for wound coverage, and did not change the survival of replantation. © 2013 Wiley Periodicals, Inc.

Comparaison de l’échographie et de l’électroneurographie pour le diagnostic du syndrome du canal carpien en pratique courante

Introduction

Many studies had been performed in the last years to prove the usefulness of ultrasonographic measurements of the median nerve in the diagnosis of carpal tunnel syndrome (CTS). We wanted to determine its reliability and to compare this technology with electromyography (EMG) in ordinary diagnostic conditions.

Methods

The study involved 90 wrists with suspected CTS, 35 controlateral wrists and 52 control wrists. The diagnosis of CTS was confirmed in 81 cases by the hand symptom diagram and the Tinnel and Phalen sign. The EMG examination evaluated medianulnar sensory latency difference to the ring finger and wrist-to-palm sensory conduction velocity. For the ultrasound diagnosis, the cross sectional area of the median nerve at the level of the pisiform bone, was considered. The sensitivity and specificity of the two techniques was calculated.

Results

Sensitive electroneurographic parameters showed a sensibility and specificity respectively of 79 and 80%. The cut-off point for ultrasound sensibility and specificity using ROC analysis was 11 mm² for mean cross-sectional area. Sensitivity and specificity found in this way were 72% and 56%. Reliability was good with intra- and inter-reader intraclass correlation coefficients of 0.99, and interobserver coefficient of 0.88. Sonography found seven CTS among the 17 clinical CTS with normal electrophysiological findings. A statistically correlation was found between the cross-sectional section and the sensitive electrophysiologic parameters (r = 0.43, p < 0.001).

Conclusions

In our study, ultrasonographic diagnostic value are not as good as electrophysiological value, like found in recent literature, probably because of the composition of our group of patients which is including many causes of acroparesthesias. This can mean that in clinical practice, sonography is a complementary tool instead, for example in cases of equivocal EMG.     

Traumatic Amputation of a Supernumerary Digit: A 16-Year-Old Boy's Perspective of Suture Ligation

Abstract:   Traditionally, the duplicated digit in an infant with polydactyly is managed by suture ligation and the digit is allowed to auto-amputate. However, painful neuromas may result from this commonly used technique and sharp excision has been suggested as a superior alternative. We present a case of a 16-year-old male who requested revascularization after a traumatic partial amputation of a supernumerary digit on his left hand. He requested revascularization because suture ligation of a duplicated digit on his right hand as an infant had resulted in a neuroma and considerable pain.     

A Population-based Study of Toenail Onychomycosis in Israeli Children

Abstract:   Onychomycosis is widespread in the adult population, but considered to be rare in children. A number of studies in recent years show a rise in the prevalence of toenail onychomycosis in children. Of these, only a few were population-based. Here, we present a comprehensive cross-sectional population-based survey of toenail onychomycosis in primary school children in Israel. The survey included 1148 children, 598 boys, and 550 girls aged 5 to 14 from primary schools in the Jerusalem vicinity. Each child underwent a physical examination and completed a personal questionnaire, which provided background information of predisposing factors. The survey shows a prevalence of 0.87% of toenail onychomycosis. Although this figure is too small for statistical analysis, some important conclusions could be drawn: prevalence increased with age: boy/girl ratio was 2.2; the dominant etiologic agent was Trichophyton rubrum followed by Trichophyton mentagrophytes and Candida albicans . Infections were probably transferred from adults via the environment to children. Infected children came from different socio-economic backgrounds. This condition should be considered in the differential diagnosis of nail diseases in children.
