    The Influence of Penetrative Trauma on the Rate of Decomposition,

    JOURNAL OF FORENSIC SCIENCES, Issue 2 2010
    Peter Cross M.Sc.
    Abstract:, An understanding of the factors affecting decomposition is important for the accurate estimation of postmortem interval. An experimental study on the influence of penetrating trauma on decomposition rate was carried out using the domestic pig, Sus scrofa. The results of this study were: (i) Diptera were preferentially attracted to and oviposited at natural orifices. Trauma sites were not preferentially selected for oviposition; (ii) no differences between trauma and non-trauma groups were found in time to skeletonization, weight loss (p = 0.906), total body score (p = 0.824), body temperature (p = 0.967), or changes in soil pH (p = 0.684); and (iii) the effect of investigator disturbance was significant when decomposition was measured as weight loss (p = 0.000). This study suggests that penetrating trauma of the type used in this study cannot be considered a major factor in the rate of decomposition and time to skeletonization of a gunshot trauma victim.

    Traumatic myiasis in dogs caused by Wohlfahrtia magnifica and its importance in the epidemiology of wohlfahrtiosis of livestock

    MEDICAL AND VETERINARY ENTOMOLOGY, Issue 2009
    R. FARKAS
    Abstract In the province of Al Hoceima, northern Morocco, and on two farms in Hungary, dogs were inspected for the presence of traumatic myiasis. Nine and four infested dogs were found in Morocco and Hungary, respectively. All the larvae and adults reared from them in the laboratory were identified as Wohlfahrtia magnifica (Schiner) (Diptera: Sarcophagidae). To our knowledge, these are the first cases of wohlfahrtiosis in dogs to be reported in these countries. All infested animals lived close to livestock, where wohlfahrtiosis was endemic. Infested body sites included limbs (six cases), external genitalia (two), ears (three), nose (one) and neck (one). Developing larvae caused severe welfare problems and tissue destruction in most cases. Although the number of cases reported here is small, wohlfahrtiosis in dogs may be very important from an epidemiological perspective because farm and stray dogs can act as both reservoirs and carriers of this parasitic fly species. Therefore, education of dog owners concerning the risk factors in endemic regions is recommended in order to reduce the prevalence of wohlfahrtiosis in dogs and thereby in livestock. Both owners and veterinarians should pay regular attention to any wounds and to the natural orifices of dogs, especially during the fly seasons. [source]

    NOTES: past, present and future

    ASIAN JOURNAL OF ENDOSCOPIC SURGERY, Issue 3 2010
    B Dallemagne MD
    Abstract Once in a few decades in science or medicine, an idea emerges that is so powerful that it changes forever how we think about that field. Natural Orifices Translumenal Endoscopic Surgery (NOTES) has the potential to break the physical barrier between bodily trauma and surgery. At the dawn of surgery, excellence was associated with big incisions: "big scar - big surgeon". In the 80s, minimally invasive surgery was born representing one of the greatest surgical evolutions of the 20th century. After Kalloo's first report in 2004 on transgastric peritoneoscopy in a porcine model, the interest in natural orifice transluminal endoscopic surgery (NOTES) has blossomed. Theoretically the same operation performed laparoscopically could be carried out through natural orifices without any abdominal incision avoiding pain and scarring. The lesson learned from the advent of laparoscopic surgery, thought us that we could be witnessing the birth of another surgical revolution. Since 2004 many abdominal procedures that use a NOTES approach have been successfully performed in animal models. However, the initial excitement for NOTES has been somewhat tempered by the reality that a NOTES procedure in human without laparoscopic assistance has not been performed by most groups. Indeed, a major issue is the lack of stable operative platform and flexible instruments that allow retraction and exposure of the organs, such as appendix or gallbladder. Will this issue change the future of NOTES? [source]

    Anatomical considerations for natural orifice translumenal endoscopic surgery

    CLINICAL ANATOMY, Issue 5 2009
    Erica A. Moran
    Abstract Success in surgical procedures relies on the surgeon's understanding of anatomy and the ways in which the internal organs relate to one another. Recently, a new surgical technique has been introduced. Natural orifice translumenal endoscopic surgery (NOTES) uses the body's natural orifices (mouth, anus, urethra, or vagina) as entrance points to the peritoneal cavities (through the stomach, rectum, bladder, or posterior vaginal fornix). NOTES techniques have proven feasible in both animal and early human trials. While it remains to be seen what advantages NOTES possesses over traditional surgical approaches, a clear understanding of human anatomy will be critical for successful, safe NOTES procedures. This article summarizes the development and the basic techniques of NOTES and reviews those anatomical considerations specific to NOTES. Clin. Anat. 22:627,632, 2009. © 2009 Wiley-Liss, Inc. [source]
