09, 0.43, 0.45 and 0.23, respectively). However, fetal MRI was more accurate for the detection of normal anatomic findings in cases with suspected microcephaly, macrocephaly and craniosynostosis in NS when pooled together (p = 0.007). Furthermore, MRI also seemed to be advantageous in CC & CSP anomalies though it was not validated by statistical measures. No statistically significant difference was found for diagnostic performance of NS and MRI according to gestational week (p = 0.27). Conclusion Fetal MRI in addition to NS may improve diagnostic accuracy in pregnancies with congenital CNS abnormalities.Objective To evaluate whether bilateral common iliac artery (CIA) temporary clamping reduces blood loss during cesarean-hysterectomy of placenta percreta cases. Study design A total of 32 women, who underwent cesarean-hysterectomy under bilateral CIA temporary clamping (n = 12) and without any arterial clamping or ligation (control group, n = 20) due to placenta percreta in Gaziantep University Hospital were retrospectively evaluated. The intra- and postoperative outcomes such as blood loss, blood transfusion and complications were compared between the two groups. Results Age, parity, body-mass-index and gestational-age were similar in the two groups. The estimated blood loss was lower in the temporary clamping of CIA group than the control group (595 ± 172 mL vs 1450 ± 662 mL, P less then 0.001). The number of intraoperative packed-red-blood-cells (0.17 ± 0.58 units vs 1.85 ± 1.46 units, P = 0.002) and fresh-frozen-plasma (0.17 ± 0.58 units vs 1.7 ± 1.49 units, P = 0.005) transfusions were lower in the CIA temporary clamping group than the control group. The rate of women, who received blood/blood products were significantly lower in the CIA temporary clamping group compared to the control group (75 % vs 16 %, P = 0.001). Duration of operation was longer in the CIA temporary clamping group (140 ± 38 min vs 90 ± 25 min, p = 0.001). No complication or maternal death was encountered during this study. Conclusion Bilateral CIA temporary clamping method reduces the intraoperative blood loss and the amount of intraoperative blood/blood product transfusions during cesarean-hysterectomy due to placenta percreta.Fingermarks are commonly found at crime scenes and can be used to link an individual to an object and/or place. One common evidence type regularly encountered in the course of a criminal investigation is banknotes, and the recovery of fingermarks from these notes can give an indication of who has handled them. This study was carried out in order to determine the most effective sequential processing techniques for recovering latent fingermarks on the new £5 and £10 Clydesdale Bank and Royal Bank of Scotland polymer banknotes. No previous studies have been published on the recovery of latent fingermarks from these types of polymer notes; therefore, this work provides valuable insight into the challenges associated with these notes. Initial experimentation was done in order to determine the best light source to be used in combination with each sequential process tested. From this, infrared (730-800nm) and ultraviolet (350-380nm) light were chosen for use in the main study. Black iron oxide powder suspension and black magnetic powder were two of the enhancement treatments tested, both of which are recommended ‘Category A’ processes in the Fingermark Visualisation Manual produced by the Home Office. Superglue fuming – using PolyCyano UV-which is a Category C process was also used, as well as the recently developed infrared fluorescent powder, fpNATURAL®2. Three fingermark donors were selected for this study-one good, one medium and one poor-and each donor deposited a 10-mark depletion series onto both sides of each type of note. Superglue fuming (using PolyCyano UV) followed by black magnetic powder was found to be the most effective sequential process for enhancement of fingermarks on all note types tested. Infrared (730-800nm) light with an 815nm filter was the most effective light source for enhancing ridge detail for this enhancement sequence. This process is now being implemented for use with these note types in Scotland.New psychoactive substances (NPS) emerge continually, amongst which is a growing class of ketamine analogues with an arylcyclohexylamine backbone. Recently we reported a poisoning outbreak associated with 2-oxo-PCE (deschloro-N-ethyl-ketamine). The present report describes the emergence of another ketamine analogue, 2-fluorodeschloroketamine (2F-DCK). The compound was first detected in a patient’s urine, its identity confirmed by accurate mass analysis and comparison with reference standard. Four putative metabolites were identified, including nor-2F-DCK, dehydronor-2F-DCK (major metabolite) and two hydroxylated derivatives of nor-2F-DCK. Between January and July 2019, 20 cases of analytically confirmed 2F-DCK exposure were encountered. In 19 out of 20 cases, at least one more ketamine-type drug was detected concurrently with 2F-DCK, including ketamine (90%), deschloroketamine (DCK, 50%), 2-oxo-PCE (45%) and tiletamine (10%). In particular, six of the cases showed the presence of 4 ketamine-type drugs in the same urine sample. The clinical effects observed in patients exposed to 2F-DCK are predominantly neurological (impaired consciousness, agitation, abnormal behaviour) and cardiovascular (hypertension, tachycardia); five patients had loss of consciousness or convulsion. Management was mainly supportive; all patients recovered uneventfully. This is the first clinical case series involving 2F-DCK and frontline medical personnel are urged to be aware of this rapidly expanding class of NPS, in particular the co-ingestion of multiple ketamine analogues.Bullet ricochet off a surface in a shooting scene occurs in diverse conditions and affected by array of factors. Therefore ricochet analysis of a particular incident demands case by case analysis supported by the knowledge of existing subject knowledge and empirical testing. In this view, existing empirical test results on bullet ricochet experiments have become always assisted and referred by investigators during scene reconstruction and in Courts. This forensic based research was aimed to understand the ricochet behaviour and related aspects of Kalashnikov bullets (7.62mm×39mm) on 1mm sheet metal. 1mm sheet metal was selected as the target surface of the study, based on its greater possibility of existing in concurrent urban environments as vehicle bodies, electrical appliances, road signs, boundary walls, partitions, walls of mobile houses etc. TRULI purchase The research added brand new knowledge to the firearm investigation field in general and specifically to AK shooting investigations and scene reconstruction. The ricochet angles and critical angle of 1mm sheet metal and AK bullets, relationship of different impact feathers and angle of incidences are some of the main findings of the research.
