RESUMO

In Maltot (Normandy, France), one grave containing the remains of a German soldier, who died in 1944, was excavated amongst other graves and isolated elements. A dozen whole vials were unearthed, resulting in questions about their content. Various screenings were carried out on the contents of one single vial: HPLC-DAD and HR-LC-MS screening after 1/10 dilution in mobile phase, GC-MS and HS-GC-MS after 1/10 dilution in methanol, multi-element research by HR-ICP-MS after total mineralization, and cyanide analysis. Analyzed vial contained approximately 300 µL of a colorless, water-immiscible liquid with a characteristic solvent odor. HPLC-DAD, GC-MS, HR-LC-MS/MS, ICP-MS, and cyanide screenings were negative excluding the presence of cyanide, arsenic, barbiturates, amphetamines, or narcotics. HS-GC-MS analysis highlighted the presence of ethanol, chloroform, and diethyl ether at significant concentrations. Chloroform and diethyl ether were anesthetic products mainly reserved for urgent situations. We hypothesized that the soldier may have been a combat medic working on battlefields. as he was wounded, another possibility could be that he may have used the vials to relieve his pain; however, the immediate severity of the wounds drove us to assess the second hypothesis of delayed death as being less plausible. The high number of vials containing ethanol, chloroform, and diethyl ether, and the massive blood loss leading to quick death led us to support the combat medic or paramedic hypothesis.

RESUMO

INTRODUCTION: Invasive breast cancer without clinical adenopathy (cN0) is currently explored by the sentinel node (GS) technique, except in the case of positive preoperative radio-cytological screening, where axillary curage (CA) remains systematic from the outset. Since the publication of the ACOSOG-Z0011 trial, abstention from CA is possible in patients presenting less than three metastatic GS. As a result, the value of axillary radio-cytological screening is being questioned as it could potentially lead to axillary surgical over-treatment. The objective of this study was to study clinically N0 patients with positive axillary cytology and to compare it to a group of patients with positive GS. METHOD: One hundred and forty-seven patients with cN0 pN+ breast cancer treated between 2014 and 2016 were selected retrospectively. Two groups were constituted according to the initial radio-cytological evaluation. A CA was systematically performed. RESULTS: Thirty-one patients with positive axillary cytology (n=31 vs. n=116) had more metastatic lymph nodes (P=0.01) in the AC, larger (P<0.001), less differentiated (P<0.001) tumours, and shorter recurrence-free survival (P=0.0114). It also appeared that 38.7 % of patients with a positive cytology had at most two metastatic nodes and could, according to the results of ACOSOG, benefit from therapeutic de-escalation. CONCLUSION: X-ray cytological screening remains essential in order to select a subgroup of patients with a high lymph node tumour load. Additional studies are necessary in order to be able to offer therapeutic de-escalation to 1/3 of these patients without the risk of under-treatment for the remaining 2/3.

RESUMO

OBJECTIVE: To compare the efficiency of double balloon catheters with that of intravaginal prostaglandins alone for the labor induction of unfavourable cervices in term nulliparous women. METHODS: 50 nulliparous patients induced with a double balloon device were compared to 53 patients induced using intravaginal prostaglandins alone. The main outcome measure was labour induction failure, characterized by the absence of active labour. The secondary outcome measures were the improvement of the Bishop score, the average durations of ripening and labour induction, the average time to active labour, the need for a second cervical ripening agent, the total dose of prostaglandins used in each group, the use of oxytocins, as well as the rates of vaginal delivery, abnormal foetal heart rate during labour and perinatal maternal infection. RESULTS: The rate of failed labour induction was of 28% in the double balloon group, against 13% in the prostaglandins group. The average durations of ripening and labour induction, as well as the time to active labour were higher in the double balloon group. The improvement of the Bishop score was significantly lower in the double balloon group. DISCUSSION AND CONCLUSION: In our study, the use of double balloon catheters does not seem to reduce the rate of failed labour induction in nulliparous women when compared to the use of prostaglandins alone. In addition, it could lengthen the labour induction duration, although more powerful studies would be necessary not to recommend its use for nulliparous women.
