Separation of congenital embryonic syndactylies in children: dorsal or volar flap? About a comparative retrospective series.

Congenital syndactylies account for 1 to 2 out of 2000 birth defects. Although several types of syndactylies exist, we only studied embryonic syndactylies. The goal of our study was to compare 2 types of coverage flap for the reconstruction of the finger web spaces: a volar flap described by Blauth and a dorsal flap described by Gilbert. Between 1993 and 2015, children affected by simple and complex syndactylies (partial or complete) were treated in 2 french pediatric hospitals and were selected for our analytic, comparative, retrospective review. The 2 hospitals used different surgical techniques: one used a volar flap described by Blauth and the other a dorsal flap described by Gilbert. The children were followed up to look for signs according to the stages of the Classification of Withey and to evaluate a global result according to the score of Withey. Our secondary criteria of judgement were the aspect of the surgical scar according to the VSS (Vancouver Scar Scale) and the satisfaction of the parents and children. The age of the children, need for a surgical revision and time of last follow- up were also studied. We found statistically significant differences between group I (volar flap) and group II (dorsal flap) in favor of the volar flap: higher scores of Withey (even when the number of commissures was increasing) and better VSS (regardless of the number of web spaces treated). There was no statistically significant difference between the 2 groups in terms of age, follow-up, or rate of surgical revision. All in all, the volar flap presented less sequelae in terms of scar retraction. Regardless of the flap used, the cosmetic results of the full-thickness skin graft used impacted the result both on the receiving site (dyschromia, hairiness) and the donor site.

RhBMP7 use for treating scaphoid non-union: 5 cases assessed at 10 years' follow-up.

The scaphoid is the most common non-union site in the wrist. Fixation with vascularised or non-vascularised autograft is the gold standard when it comes to treating these non-unions. But, what can we offer if the autograft fails? Using osteoinductive proteins in difficult cases of long bone non-union yields good results. However, only a few studies have been published on their use for scaphoid non-union. In our study, five patients with an average age of 32 years (ranging from 21 to 44 years) with old non-union (more than 24 months) of the scaphoid were treated after autograft treatment had failed. The procedure consisted of reaming the non-union site, then adding bone autograft combined with BMP-7 (Osigraft®) in the defect and fixing it all with a screw or K-wire. Postoperative immobilisation was prescribed. Only one patient achieved bone union (20%) despite an average follow-up of 10 years (80-143 months). The average flexion-extension loss was 16.6° (0-30) relative to the contralateral side. The average strength deficit was 450 grams (0-2000) for pinch and 12.1kg (0-29) for grip compared to the contralateral side. Self-assessment questionnaires had an average PRWE at 28.9 (10.5-49) and an average QuickDASH at 28.6 (9.09-61.36). Our study could not demonstrate any real benefit of using BMP-7 for treating old scaphoid non-union despite an elevated cost. Further research is needed to look at other treatment approaches, for instance, the use of new scaffolds combining VEGF and BMP.

[Results of Blauth Palmar Flap in congenital syndactyly: Long-term outcome in a 31 webs study]. / Évaluation du lambeau palmaire de Blauth lors de la prise en charge des syndactylies congénitales : à propos de 31 commissures.

OBJECTIVES: The main purpose of our study was to assess the web creep rate of congenital syndactyly treated with a Blauth palmar commissural flap. METHODS: Every child with at least one syndactyly, simple or complex, syndromic or not, were included in this study. The main criterion of this study was the web creep rate according to the Withey scale (0 to 4). Scar assessment according to the Vancouver Scar Scale, hair growth and/or dyschromia on the full-thickness graft, digital spacing, flexion deformity, clinodactyly, range of motion of the finger, sensitivity and satisfaction were also assessed. RESULTS: Separation of the webbed fingers was performed in 65 syndactylies between 1993 and 2015. The median age at the time of surgery was 14 months. We reviewed 31 web flaps with a mean follow-up time of 9 years. Fifty eight percent of the webs were grade 0 on the Withey scale, 36% were grade 1, 6% were grade 2. There was no grade 3 or 4. No correlation was found between the age at the time of surgery, gender, web space involved, complexity of the syndactyly, and the web creep. A decrease in range of motion and a flexion deformity of the fingers involved were more frequently found in complex syndactylies. Eighty seven percent of full-thickness grafts presented dyschromia, and 42% abnormal pilosity. CONCLUSION: Palmar flap as described by Blauth is a safe technique ensuring good functionals outcomes and a low web creep rate for the reconstruction of the web space in congenital syndactyly.

Usefulness of ultrasound for the diagnosis of pyogenic flexor tenosynovitis: A prospective single-center study of 57 cases.

Pyogenic flexor tenosynovitis (PFT) is a functional emergency in hand surgery; however, its diagnosis can be difficult to make. It should always be considered when a patient presents with an inflamed finger. The goal of this study was to investigate the usefulness of ultrasound in the diagnosis of early PFT. Seventy-three patients with suspected pyogenic flexor tenosynovitis were candidates for the study. Since the diagnosis of PFT was obvious in 16 patients, they were excluded from the study and immediately underwent surgery. The remaining 57 patients underwent a clinical examination by a senior surgeon, a blood test for C-reactive protein levels and an ultrasound (US). The US results were compared to the intraoperative findings if the patients were operated or to the clinical outcome in non-operated patients. Seventeen patients had the US diagnosis of PFT confirmed intraoperatively. In 10 patients, the US diagnosis of PFT was not confirmed intraoperatively. In 29 other patients, the diagnosis of PFT was ruled out by US; they all had good outcomes after being treated with antibiotics. In one patient for whom the diagnosis of PFT had been ruled out by US, PFT was actually present. Ultrasound had 94% sensitivity, 65% specificity, 63% positive predictive value, and 95% negative predictive value. Ultrasound is useful as a diagnostic tool for managing early PFT thanks to its excellent negative predictive value and specificity. This objective examination complements the surgeon's subjective clinical examination.

Upper limb nerve transfers: A review.

While upper limb nerve transfers were first described and performed several years ago, they have seen expanded use in the past 20 years. Initially indicated for surgical repair of brachial plexus injuries with nerve root avulsion, the indications have been extended to post-ganglionic lesions because of the excellent results of certain intraplexus nerve transfers. The traditional nerve repair techniques - primary suture and nerve grafting - form the basis of nerve surgery. Although nerve transfer does not replace them, they are a useful supplement as they provide a targeted approach to reinnervation and recovery of key functions of the upper limb. The goal of this review is to provide an overview of the various possible transfers by the function being restored and the quality of the outcomes.

Dramatic reduction in Clostridium difficile ribotype 027-associated mortality with early fecal transplantation by the nasogastric route: a preliminary report.

Clostridium difficile ribotype 027 (CD027)-associated diarrhea preferentially affects elderly patients and causes a high mortality rate. Fecal microbiota transplantation has become an alternative treatment for recurrent C. difficile infections. An outbreak of CD027 infections has occurred in Marseille since March 2013. From March to November 2013, we treated patients using only antibiotics or fecal microbiota transplantation after at least three relapses. Beginning in November 2013, we performed early transplantation using a nasogastric tube during the first week of infection, in combination with antibiotic treatment. Sixty-one patients with a mean age of 84 years were hospitalized, including 42 patients treated only with antibiotics, three with tardive transplantation, and 16 with early transplantation. The patients were comparable in clinical involvement. The global mortality rate was 3/16 (18.75 %) among the patients treated by early transplantation and 29/45 (64.4 %) among the patients only treated by antibiotics or by tardive transplantation (p < 0.01). Among these 45 patients, 23 (51 %) died at day 31, including 17 who died at day 7. Early fecal transplantation was associated with a significantly reduced mortality rate, with only one patient dead at day 31 (6.25 %). In a Cox model, early transplantation was the only independent predictor of survival (hazard ratio 0.18, 95 % confidence interval 0.05-0.61, p = 0.006). Six of the 16 patients (37.5 %) needed a second transplantation before symptom resolution. Early fecal microbiota transplantation in combination with antibiotics should be the first-line treatment for CD027 infections.

Cutaneous and pulmonary dirofilariasis due to Dirofilaria repens.

Dirofilariasis is a worldwide zoonotic infection that accidentally affects humans. It is caused by filarial nematodes of the genus Dirofilaria, which are transmitted by mosquitoes. Cutaneous dirofilariasis appears as inflammatory lesions that could be consistent with Wells' cellulitis. We present a remarkable case of human infection with Dirofilaria repens, causing both subcutaneous and pulmonary nodules.

Leptospirosis presenting as honeymoon fever.

An increasing number of travelers from western countries visit tropical regions, questioning western physicians on the prophylaxis, the diagnosis and the therapeutic management of patients with travel-associated infection. In July 2014, a French couple stayed for an adventure-travel in Columbia without malaria prophylaxis. A week after their return the woman presented with fever, myalgia, and retro-orbital pain. Three days later, her husband presented similar symptoms. In both patients, testing for malaria, arboviruses and blood cultures remained negative. An empirical treatment with doxycycline and ceftriaxone was initiated for both patients. Serum collected from the female patient yielded positive IgM for leptospirosis but was negative for her husband. Positive Real-Time PCR were observed in blood and urine from both patients, confirming leptospirosis. Three lessons are noteworthy from this case report. First, after exclusion of malaria, as enteric fever, leptospirosis and rickettsial infection are the most prevalent travel-associated infections, empirical treatment with doxycycline and third generation cephalosporin should be considered. In addition, the diagnosis of leptospirosis requires both serology and PCR performed in both urine and blood samples. Finally, prophylaxis using doxycycline, also effective against leptospirosis, rickettsial infections or travellers' diarrhea should be recommended for adventure travelers in malaria endemic areas.

Prognostic impact of 18F-FDG PET/CT staging and of pathological response to neoadjuvant chemotherapy in triple-negative breast cancer.

PURPOSE: Mortality is high in patients with locally advanced triple-negative breast cancer (TNBC), especially in those with residual tumour after neoadjuvant chemotherapy (NAC). The aim of this study was to determine if pretreatment (18)F-FDG PET/CT staging and pathological findings after NAC could together allow stratification of patients into prognostic groups. METHODS: Initial staging with (18)F-FDG PET/CT was performed prospectively in 85 consecutive patients with stage II/III TNBC. Correlations between PET findings and disease-specific survival (DSS) were examined. In patients without distant metastases on PET staging, the impact of pathological response to NAC on DSS was examined. Patterns of recurrence were also analysed. RESULTS: (18)F-DG PET/CT revealed distant metastases in 11 of 85 patients (12.9 %). Among 74 M0 patients, 23 (31.1 %) showed a pathological complete response (pCR) at surgery, while 51 had residual invasive disease (no pCR). DSS differed considerably among the three groups of patients (log-rank P < .001): among patients with occult metastases on baseline PET/CT, 2-year DSS was 18.2 %, and among patients without initial metastases on PET/CT, 5-year DSS was 61.3 % in patients without pCR after NAC and 95.2 % in those with pCR. Of the 51 patients who did not achieve pCR, 21 relapsed (17 developed distant metastases). The sites of distant recurrence were: lung/pleura (nine patients), brain (eight patients), liver (six patients), distant lymph nodes (six patients) and bone (five patients). CONCLUSION: In patients with clinical stage II/III TNBC, (18)F-FDG PET/CT findings at initial staging and pathological response at the end of NAC allow three groups of patients with quite different prognoses to be defined. Extraskeletal recurrences predominated. Specific follow-up strategies in patients with TNBC who do not achieve pCR deserve investigation.
