Enquête sur les pratiques françaises d’analgésie en chirurgie thoracique (réalisée avec le concours de l’ARCOTHOVA)

Objective

To assess the current practice of analgesia after thoracotomy and thoracoscopy in France.

Study design

Cross-sectional practice survey.

Material

Anaesthetist physicians, each referent for one of the French centres practicing thoracic surgery, during year 2012.

Methods

Electronic questionnaire about the activity of the centre in thoracic surgery, and modalities and estimated frequencies of different analgesic techniques. Primary assessment was the estimated percentage of acts, after imputation from original data.

Results

Eighty-four centres out of 103 (82 %) answered the questionnaire. Coupling locoregional to general anaesthesia involved 74 % of thoracotomies and 35 % of thoracoscopies. A practice (i.e. for more than 5 % of patients) of epidural analgesia was declared by 68 centres (81 %), and by 27 centres (32 %) for paravertebral block. The most current practices for epidural analgesia were: thoracic puncture, intraoperative initiation, ropivacaïne 0.2 % plus sufentanil, patient-controlled administration with infusion plus bolus, application more than 48 hrs post surgery. The practice rates for technique of paravertebral block were: Eason & Wyatt 34 %, ultrasound-guided 24 %, internal 42 %. The most frequent systemic analgesia was patient-controlled intravenous morphine. Ketamine was used in 60 % of the cases.

Conclusions

French practice of analgesia after thoracic surgery improved quality during the last decade, but more than one patient on four (compared to 8 % in UK) may have neither epidural nor paravertebral block, while such techniques are nowadays considered as standard.     

Potential utility of bone scan in cranial bone flap osteomyelitis

Is There a Role for Visceral Adiposity in Inducing Type 2 Diabetes Remission in Severely Obese Patients Following Biliopancreatic Diversion with Duodenal Switch Surgery?

Background

Severe obesity is often characterized by ectopic fat deposition, which is related to development of type 2 diabetes (T2D). Thus, resolution of T2D may not be linearly associated with weight loss. The importance of ectopic fat reduction after bariatric surgery and T2D resolution is uncertain.

Objective

The aim of this pilot study is to compare body composition and body fat distribution in severely obese patients with or without T2D after biliopancreatic diversion with duodenal switch (BPD-DS) surgery in relation to diabetes resolution.

Methods

Sixty-two severely obese patients were evaluated at baseline, 6, and 12 months. Of these, 40 patients underwent BPD-DS surgery. Anthropometric measurements and abdominal and mid-thigh computed tomography scans were performed at each visit.

Results

Before BPD-DS surgery, obese patients with T2D had higher weight as well as greater ectopic fat deposition in the abdomen and mid-thigh level than obese patients without T2D (p?<?0.05). Resolution of T2D was 65 and 90 % at 6 and 12 months, respectively. No difference in body composition changes at 6 and 12 months could be found between patients without T2D, patients with T2D resolution, and patients who remained T2D. Resolution of T2D was associated with a greater absolute loss of visceral adipose tissue (VAT) in comparison to patients without T2D (?1175?±?570 cm³ vs. ?729?±?394 cm³ at 6 months and ?1647?±?816 cm³ vs. ?1103?±?422 cm³ at 12 months; all p?≤?0.05).

Conclusion

Ectopic fat mobilization, particularly the absolute loss of VAT, may play a major role in T2D resolution following BPD-DS surgery, regardless of the amount of weight loss.

     

HLA-B*0749N: the first HLA-B*07 null allele

In the present article, we report the identification of the first HLA-B*07 null allele found in a Polish patient awaiting a kidney allograft. A discrepant result obtained between serological typing (HLA-B "blank") and high-resolution molecular typing using PCR-SSP method (HLA-B*070201 allele) suggested the presence of a null allele. Genomic DNA sequencing of the HLA-B*07 allele revealed a single nucleotide substitution at the 3' end of the exon 4 leading to a premature stop codon.     

MRI-targeted biopsy for detecting prostate cancer: have the guidelines changed our practices and our prostate cancer detection rate?

International Urology and Nephrology - In our center, until 2018, MRI-targeted biopsy was underused. Since January 2018, we systematically performed MRI-targeted biopsy for suspicious...
