Head/skull injury potential of empty 0.5-l beer glass bottles vs. 0.33-l Coke bottles.

The medical and biomechanical assessment of injuries from blows to the head is a common task in forensic medicine. In the context of a criminal justice process, the injury potential of different striking weapons is important. The article at hand compares the injury potential of assaults with a 0.5-l beer bottle and a 0.33-l Coke bottle, both made of glass. The research team hit 30 used empty 0.5-l beer bottles and 20 used empty 0.33-l Coke bottles manually on an aluminum dummy skull set on a force measuring plate, using acrylic and pork rind as a scalp surrogate. There was no significant difference in fracture threshold and energy transfer between the examined beer and Coke bottles. Both glass bottles are able to cause fractures to the facial bones while cranial bone fractures are primarily not to be expected. Blows with a 0.5-l beer bottle or with a 0.33-l Coke bottle to the head can transfer up to 1.255 N and thus are able to cause severe blunt as well as sharp trauma injuries.

Perceptions and experiences of female burn survivors with facial disfigurement.

PURPOSE: This study aimed at exploring the perceptions and experiences of female burn survivors with facial disfigurement in Pakistan. METHODS: Two different quantitative and qualitative studies were conducted, of which the data were collected from 100 burn patients. A pilot interview protocol was developed. An indepth interview of five female burn survivors with facial disfigurement was taken in Lahore, Pakistan. The transcripts were analyzed using thematic analysis and four major themes were identified, respectively physical appearance, posttraumatic growth, relationships and coping strategies. RESULTS: Thematic analysis reflected differences in attributional style, perceptions and individual experiences of female burn survivors with facial disfigurement. The study showed the importance of physical appearance for different burn survivors and how their life had changed after suffering from a burn injury. CONCLUSION: It could be easy to have a positive outlook towards life and accept visible differences post injury for the burn survivors, who are grateful for life, get a strong family support and have available resources. On the contrary, with low self-esteem, lack of a family support and available resources, patients would be dissatisfied with their life.

Identifying Injury Patterns Associated With Physical Elder Abuse: Analysis of Legally Adjudicated Cases.

STUDY OBJECTIVE: Elder abuse is common and has serious health consequences but is underrecognized by health care providers. An important reason for this is difficulty in distinguishing between elder abuse and unintentional trauma. Our goal was to identify injury patterns associated with physical elder abuse in comparison with those of patients presenting to the emergency department (ED) with unintentional falls. METHODS: We partnered with a large, urban district attorney's office and examined medical, police, and legal records from successfully prosecuted cases of physical abuse of victims aged 60 years or older from 2001 to 2014. RESULTS: We prospectively enrolled patients who presented to a large, urban, academic ED after an unintentional fall. We matched 78 cases of elder abuse with visible injuries to 78 unintentional falls. Physical abuse victims were significantly more likely than unintentional fallers to have bruising (78% versus 54%) and injuries on the maxillofacial, dental, and neck area (67% versus 28%). Abuse victims were less likely to have fractures (8% versus 22%) or lower extremity injuries (9% versus 41%). Abuse victims were more likely to have maxillofacial, dental, or neck injuries combined with no upper and lower extremity injuries (50% versus 8%). Examining precise injury locations yielded additional differences, with physical elder abuse victims more likely to have injuries to the left cheek or zygoma (22% versus 3%) or on the neck (15% versus 0%) or ear (6% versus 0%). CONCLUSION: Specific, clinically identifiable differences may exist between unintentional injuries and those from physical elder abuse. This includes specific injury patterns that infrequently occur unintentionally.

Fatal craniofacial circular-saw-related injury: a rare case of accidental death.

Fatal injuries caused by circular saws are rare and mainly self-inflicted. To the best of our knowledge this is the first recorded case of accidental death of a woman caused by an injury to the head region inflicted by a saw blade. The autopsy showed a 35 cm long wound, stretching from the right half of the jaw along the right side of the face and the right temporal region up to the parietal region. The cut went through the right hemisphere of the brain in the temporal and parietal lobe regions, damaging the sagittal sinus. Air embolism was considered to be the cause of death. Fatalities involving power tools, such as a circular saw, warrant a high degree of suspicion of criminal activity and require a comprehensive medicolegal investigation. Placing guards over the blade and around the driving system, i.e. the motor, belt, arbor, is of great importance for the prevention of potentially fatal injuries.

Methods in population study of orofacial injuries in Victorian family violence homicides.

This study standardized the methods used in the determination of orofacial injuries in Victorian family violence homicides and informed potential control selection for an analytic study. Dental service contacts with family violence victims may be intervention avenues due to the presence of abusive injuries in the orofacial region. All Victorian family homicides from January 2000-September 2018 were identified by determining the kinship/relationship and grouped by age. A 20% random sample of adult cases, aged 18-64 years was selected. The median number of orofacial injuries in categories of injury mechanisms/age/gender and the nature of abusive orofacial injuries was reported for the sample. Of 357 closed cases of family homicide, 261 were adults aged 18-64 years. Offender information and injury mechanism data was available for all closed cases, enabling case selection. Of a random sample of 50 adults, 8 cases were excluded. After 2006, CT scans and photos were present in 20 (91%) and 19 (86.4%) of 22 cases, respectively. The nature and median number of orofacial injuries showed correlation to the reported injury mechanism. Strengths and limitations of the used methods were assessed. Not all cases were compatible for assessment of orofacial injuries, thus serving as an additional criterion for exclusion in our methodology. Further detailed study of the whole population of adults should be limited to the period 2006-2018 where the data is more complete. The mechanism of injury may influence control selection for analytic studies. We present preliminary evidence of the frequent occurrence of orofacial injuries in family violence homicides.

Comparison of cosmetic appearances after facial lacerations repaired by junior residents and experts.

PURPOSE: The technical factors which improve cosmetic outcomes and which need to be emphasized in education of junior residents have yet to be described. We compared cases in which suturing was performed by either junior emergency medicine residents or experts, in order to determine the focus of future education and training. METHODS: Wound registry data was reviewed and retrospectively analyzed from September 2015 to February 2016. Only patients who visited the emergency room with facial lacerations were enrolled, and their wound registry data sheets were reviewed. Practitioners were divided into junior resident and expert groups. We assessed the progress using the Stony Brook Scar Evaluation Scale (SBSES) 5-10 days following suturing. RESULTS: Sixty-six patients were enrolled; 43 (65.2%) were men. The median (interquartile range) cosmetic scores (SBSES scale) for suturing performed by junior residents or experts were 3 (2-4) and 5 (4-5), respectively (p = 0.001). The percentage of maximum scores for each SBSES category was significantly lower in the junior resident group than in the expert group for width (68% vs. 86%), hatch marks (68% vs. 93%), and overall appearance (41% vs. 80%) (all p < 0.001). CONCLUSIONS: There were significant differences in scar widths and hatch marks, which were attributable to the skill level of the practitioner who performed the suturing of facial lacerations. Junior residents should be educated about maintenance of proper tension, atraumatic technique, and performing appropriate trimming or debridement.

A proclaimed accidental fall of an infant-an experimental case reconstruction study.

The differentiation between a non-accidental injury and injuries resulting from accidents, such as falls to the ground or onto various objects, is a challenge not only for forensic experts but also for all clinicians caring for children. The forensic-biomechanical analysis of accidents in infants aims at the assessment of the loading characteristics based on the reconstruction of the particular incident. It includes an evidence-based analytical comparison between the actual injuries presented and the injuries that should be expected as a result of the proclaimed accident. With the help of kinematical and dynamical parameters of the described actions and the resulting loading situations, the forensic-biomechanical analysis can assess the plausibility of the proclaimed course of the event and thus contribute to the differentiation between accidental and non-accidental injuries. The quality of such a forensic-biomechanical expert opinion depends on the accuracy and quantity of available data regarding biomechanical tolerance of tissues, organs, and body parts. Case-specific measurements can contribute significantly to the insight of the kinematics and dynamics of the proclaimed event, its feasibility, etc. The present article demonstrates, based on one case report, the potential as well as the limits of such an analysis of proclaimed accidental fall injuries.

Violence in paradise: Cranial trauma in the prehispanic population of Gran Canaria (Canary Islands).

OBJECTIVES: This paper addresses the prevalence and pattern of physical violence in the prehispanic society of Gran Canaria and discusses its link with the social structure and insular context in which that people lived. MATERIALS AND METHODS: 347 prehispanic crania from Guayadeque Ravine (575-1415 AD) have been examined in order to determine the frequency, types, location, and timing of trauma. RESULTS: Craniofacial injuries are present in 27.4% of the crania examined. Only 2% display perimortem trauma. Most of the injuries (84.3%) correspond to depressed blunt force trauma, with an ellipsoidal or circular shape. Most of these are in the anterior aspect of the cranium. Males are significantly more affected than females. DISCUSSION: The aboriginal population of Gran Canaria show a high frequency of traumatic injuries to the skull compared to other archaeological groups. Their frequent location in the anterior aspect suggests regular face-to-face confrontations. However, the lethal injuries typically occurring in large-scale combat are scarce. Practices such as ritualized combat, mentioned in ethnohistorical sources, would help to channel and mitigate inter-group conflict. The predominance of depressed blunt force trauma is in accordance with the weapons used by those populations: hand-thrown stones, clubs and sticks. The higher frequency in males indicates that they took part in direct violence more than females did. The hierarchical organization of their society may have led to frequent situations of conflict. The insular nature of a territory barely 1,500 m2 in size was a determining factor in competition for access to food resources, especially at times of climate crises or population growth.

Error rate of automated calculation for wound surface area using a digital photography.

BACKGROUND: Although measuring would size using digital photography is a quick and simple method to evaluate the skin wound, the possible compatibility of it has not been fully validated. PURPOSE: To investigate the error rate of our newly developed wound surface area calculation using digital photography. METHODS: Using a smartphone and a digital single lens reflex (DSLR) camera, four photographs of various sized wounds (diameter: 0.5-3.5 cm) were taken from the facial skin model in company with color patches. The quantitative values of wound areas were automatically calculated. The relative error (RE) of this method with regard to wound sizes and types of camera was analyzed. RESULTS: RE of individual calculated area was from 0.0329% (DSLR, diameter 1.0 cm) to 23.7166% (smartphone, diameter 2.0 cm). In spite of the correction of lens curvature, smartphone has significantly higher error rate than DSLR camera (3.9431±2.9772 vs 8.1303±4.8236). However, in cases of wound diameter below than 3 cm, REs of average values of four photographs were below than 5%. In addition, there was no difference in the average value of wound area taken by smartphone and DSLR camera in those cases. CONCLUSION: For the follow-up of small skin defect (diameter: <3 cm), our newly developed automated wound area calculation method is able to be applied to the plenty of photographs, and the average values of them are a relatively useful index of wound healing with acceptable error rate.

Face allotransplantation for various types of facial disfigurements: A series of five cases.

BACKGROUND: The aim of this report is to present our long-term experiences with a series of 5 face-transplanted patients in terms of surgical aspects and postoperative outcomes, and to describe possible salvage strategies in case of difficulties. METHODS: Five patients, 4 receiving full-face transplantation and 1 undergoing partial transplantation at our institution were included. The patients were aged between 19 and 54 years. Two had extensive burn scars to the face, and 3 had suffered gunshot injuries. The post-transplant induction immunosuppressive regimen included ATG combined with tacrolimus, mycophenolate mofetil, and prednisone, while maintenance was provided by the last 3. We focused on patient summaries including their etiologies, preoperative preparations, surgical techniques, immunosuppressive regimen, postoperative courses, revisional surgeries, together with challenges including acute rejection episodes, and immunosuppressive drug complications. RESULTS: No re-surgery due to vascular compromise was required in any case. One of the 5 patients was eventually lost due to complicated infectious and metabolic events at the end of post-transplantation month 11. The other 4 patients were still alive, with a mean follow-up time of 53 months and had satisfactory functional transplants and cosmetic appearance. CONCLUSIONS: Face transplantation still involves challenges and many issues including compliance and psychological maturity of patients, the risk of opportunistic infections and malignancies still need to be resolved for it to be accepted as a safe procedure. Surgical rescue procedures considering ideal timing should be kept in mind strictly as one of the most important issues in case of unexpected events.

Nose resurfacing with free fasciocutaneous flaps in burns patients.

BACKGROUND: Nasal reconstruction after burn injury can be challenging due to limited availability of local flaps. We present our experience of free flap reconstruction for full-thickness nasal defect after severe facial burn injury. METHODS: Between August 1998 and September 2015, six patients underwent nasal reconstruction with seven free flaps after burn injury. Among them, flame burn occurred in two patients, chemical burn in two, explosive burn in one, and contact thermal burn in one patient. The percentage of total body surface area ranged from 4% to 48%, and the face and forehead were involved in all patients. Their clinical and photographic records were retrospectively reviewed to evaluate the aesthetic results. RESULTS: Four ulnar forearm flaps, one radial forearm flap, one anterolateral thigh flap, and one medial sural artery perforator flap were used for nasal reconstruction. The nasal framework was constructed simultaneously using costal cartilage or conchal cartilage. The facial artery and vein were typically used as recipient vessels. One case each of partial necrosis and infection were noted during the average follow-up of 59 months (range, 16-126 months). Patients had satisfactory aesthetic and functional outcomes after 4.5 times (range, 2-7 times) refinement operation. CONCLUSIONS: Free flap is an applicable alternative to restore nasal skin envelope, with rebuilding the nasal framework performed in the same stage after severe facial burn injury. Through thoughtful planning and sufficient refinement, satisfactory aesthetic, and functional results are achievable.

Reconstruction of full-thickness cheek defect with chimeric facial artery free flap: A case report.

Full-thickness cheek defects represent a difficult challenge for reconstructive surgeons. Multiple techniques have been described, including local, regional, and free flaps. In this report, the reconstruction of a through and through left cheek defect, resulting from a self-inflicted gunshot injury, with a chimeric facial artery free flap is presented. The patient underwent reconstruction with a chimeric full-thickness facial artery free flap, with 9 × 3 cm diameter skin paddle and a 6 × 5 cm myomucosal paddle, was harvested on the contralateral cheek with a 7-cm length of facial pedicle. The flap was transferred via a microsurgical technique and an end-to-end microsurgical anastomosis was performed between the donor and the contralateral facial vessels. The flap was transplanted successfully and there were no donor or recipient site complications with a satisfactory esthetic result 5 years after surgery. This technique may be a good reconstructive option for medium size, full-thickness, cheek defects allowing a "like with like" reconstruction with minimal donor-site morbidity.

More than just the helix: A series of free flaps from the ear.

AIM: We herein present our experience using free flaps harvested from the ear region in facial, nasal and intraoral reconstruction. PATIENTS AND METHODS: Between 2011 and 2016, 19 patients underwent reconstruction using 20 free flaps from the ear region based on the superficial temporal vessels. There were 10 males and 9 females with a mean age of 57 years. Defect aetiology consisted of post-tumour ablation (n = 15), trauma (n = 2) and burn scar (n = 2). Defect location involved the nose (n = 13), floor of mouth (n = 3), tongue (n = 1), lower eyelid (n = 1), and lower lip (n = 1). RESULTS: Twelve helical, seven temporal artery posterior auricular skin (TAPAS), and one hemiauricular flap were performed. One patient required venous re-anastomosis but complete flap necrosis eventually occurred. This patient later underwent successful contralateral helix flap reconstruction. Overall flap survival was 95%. Follow-up ranged from 12 to 69 months. A moderate to excellent aesthetic and functional outcome was achieved in all cases, but most (13/19) required later minor refinement surgery. CONCLUSION: As a versatile source of free flap options, the ear can provide more than just the helix.

Usefulness of direct W-plasty application to wound debridement for minimizing scar formation in the ED.

PURPOSE: A suture line placed with the same direction as the relaxed skin tension line leads to good healing, but a suture line with over 30 degrees of angle from the relaxed skin tension line leads to longer healing time and more prominent scarring. W-plasty is widely used to change the direction of the scar or to divide it into several split scars. In this study, we applied W-plasty to patients with facial lacerations in the emergency department. METHODS: From June 2012 to December 2014, 35 patients underwent simple repair or W-plasty for facial lacerations. Patients in the simple repair group underwent resection following a thermal margin, and the W-plasty group was resected within a pre-designed margin of W-shaped laceration. We assessed prognosis using the Stony Brook Scar Evaluation Scale (SBSES) after 10 days (short-term) and six months (long-term), respectively, following suture removal. RESULTS: Among 35 patients, 15 (42.9%) underwent simple debridement and 20 (57.1%) underwent W-plasty. In the W-plasty group, there was no difference between short-term and long-term follow-up showing high SBSES, but in the simple debridement group, long-term follow-up SBSES significantly decreased. W-plasty SBSES was higher than simple debridement at short-term as well as long-term follow-up. CONCLUSION: We experienced good results of direct W-plasty application at six-month long-term follow-up. Therefore, W-plasty application is more effective in reducing scar appearance than a simple debridement method for facial laceration patients with an angle of 30 degrees or more to the relaxed skin tension line.

Histomorhological and clinical evaluation of maxillary alveolar ridge reconstruction after craniofacial trauma by applying combination of allogeneic and autogenous bone graft.

A variety of techniques and materials for the rehabilitation and reconstruction of traumatized maxillary ridges prior to dental implants placement have been described in literature. Autogenous bone grafting is considered ideal by many researchers and it still remains the most predictable and documented method. The aim of this report is to underline the effectiveness of using allogeneic bone graft for managing maxillofacial trauma. A case of a 30-year-old male with severely atrophic maxillary ridge as a consequence of complex craniofacial injury is presented here. Augmentation procedure in two stages was performed using allogeneic and autogenous bone grafts in different areas of the osseous defect. Four months after grafting, during the implants placement surgery, samples of both sectors were withdrawn and submitted to histological evaluation. On the examination of the specimens, treated by hematoxylin and eosin staining, the morphology of integrated allogeneic bone grafts was revealed to be similar to the autologous bone. Our clinical experience shows how the allogeneic bone graft presented normal bone tissue architecture and is highly vascularized, and it can be used for reconstruction of severe trauma of the maxilla.

["Palimpsest scar" lesions in a context of torture (Darfur, Sudan)]. / Cicatrices « palimpsestes ¼ en contexte de torture (Darfour, Soudan).

BACKGROUND: As a result of the current exponentially growing refugee population from the Middle-East and East Africa (Sudan, Darfur, Eritrea), clinicians (including forensic pathologists) are seeing atypical skin lesions, mainly of a traumatic nature, but in some cases associated with long-standing lesions related to ethnic practices. PATIENTS AND METHODS: A case of torture sequelae is presented herein in a patient originally from Darfur (Sudan): cutaneous incisions were made on old scars several times using a knife. DISCUSSION: The clinical presentation of scarification lesions and that of atypically healed wounds (presumably an effect of inflammation induced by the introduction of irritating foreign bodies such as sand, salt, etc.) are completely different: in all cases they indicate a relative timeframe of the facts, which the clinician should not overlook in reconstructing the patient's course and the injuries to which he has been subjected (hence the proposed designation of "palimpsest scar", in the sense that a palimpsest is a manuscript on a parchment that previously contained writing but has been scratched clean to be overwritten). Thus, a "palimpsest scar" constitutes a fresh scar on top of and hiding another (ritual) scar in a context of ethnic cleansing. The diagnostic and clinical significance comes from the importance of differentiating between ethnic-type lesions and those induced by physical violence and abuse in a context of war.

Perimortem trauma in King Richard III: a skeletal analysis.

BACKGROUND: Richard III was the last king of England to die in battle, but how he died is unknown. On Sept 4, 2012, a skeleton was excavated in Leicester that was identified as Richard. We investigated the trauma to the skeleton with modern forensic techniques, such as conventional CT and micro-CT scanning, to characterise the injuries and establish the probable cause of death. METHODS: We assessed age and sex through direct analysis of the skeleton and from CT images. All bones were examined under direct light and multi-spectral illumination. We then scanned the skeleton with whole-body post-mortem CT. We subsequently examined bones with identified injuries with micro-CT. We deemed that trauma was perimortem when we recorded no evidence of healing and when breakage characteristics were typical of fresh bone. We used previous data to identify the weapons responsible for the recorded injuries. FINDINGS: The skeleton was that of an adult man with a gracile build and severe scoliosis of the thoracic spine. Standard anthropological age estimation techniques based on dry bone analysis gave an age range between 20s and 30s. Standard post-mortem CT methods were used to assess rib end morphology, auricular surfaces, pubic symphyseal face, and cranial sutures, to produce a multifactorial narrower age range estimation of 30-34 years. We identified nine perimortem injuries to the skull and two to the postcranial skeleton. We identified no healed injuries. The injuries were consistent with those created by weapons from the later medieval period. We could not identify the specific order of the injuries, because they were all distinct, with no overlapping wounds. Three of the injuries-two to the inferior cranium and one to the pelvis-could have been fatal. INTERPRETATION: The wounds to the skull suggest that Richard was not wearing a helmet, although the absence of defensive wounds on his arms and hands suggests he was still otherwise armoured. Therefore, the potentially fatal pelvis injury was probably received post mortem, meaning that the most likely injuries to have caused his death are the two to the inferior cranium. FUNDING: The University of Leicester.

When the prey gets too big: an uncommon road accident involving a motorcyclist, a car and a bird.

We present the postmortem findings of a fatal road accident involving a motorcyclist, a car, and a common buzzard. Both the motorcyclist and the bird died on the scene of the accident and were examined by postmortem full-body CT and autopsy. In addition, a facial injury of the motorcyclist was compared with the dimensions of the buzzard's beak and claws by 3D scan technologies. Blood splatters collected on the bird's beak, feet, and tail were examined by DNA analysis. The overall findings suggested a collision of a common buzzard with a motorcyclist in full speed, causing the motorcyclist to lose control of his vehicle and crash with an approaching car on the oncoming lane.

Interpersonal Violence Is Associated With Increased Severity of Geriatric Facial Trauma.

PURPOSE: The geriatric population is rapidly increasing in number with increased demand on health care resources including those spent on the treatment of maxillofacial trauma. The purpose of this analysis was to investigate the independent and cumulative associations between potential risk factors (age, gender, mechanism of injury, drug use, and alcohol use) for and the severity of geriatric facial trauma. METHODS: This was a cross-sectional analysis of secondary data of geriatric (individuals aged ≥65 years) facial trauma using the Allegheny General Hospital Trauma Registry database. Data were collected for diagnosis codes that reflected facial trauma (International Classification of Diseases, Ninth Revision codes 802.0 to 802.9, 800.1 to 801.9, and 803.0 to 804.9) and specific mechanisms of injury (E810 to E819, motor vehicle traffic accidents; E880 to E888, accidental falls; and E960 to E969, injury purposely inflicted by other persons). The Facial Injury Severity Scale (FISS) is a validated measurement that was used to determine the severity of the facial trauma and calculated through analysis of the abstracted data obtained from the trauma registry and patient records. Pearson correlations, 2-way independent t test, 1-way analysis of variance, and multiple linear regression were used to test hypotheses for independent and cumulative associations between the risk factors for and the severity of geriatric facial trauma. Statistical significance was set at the P < .05 level. RESULTS: The sample was composed of 229 patients with a mean age of 72.3 ± 4.5 years. A statistically significant association between mechanism of injury and the severity of geriatric facial trauma (P = .019) was found. Specifically, interpersonal violence (assault) was associated with the greatest facial trauma severity (FISS score, 4.2) when compared with motor vehicle collisions (FISS score, 2.2; P = .011) and falls (FISS score, 2.4; P = .016). CONCLUSIONS: Interpersonal violence (assault) is associated with increased severity of geriatric facial trauma compared with other risk factors.

Bipedicled Preexpanded Forehead Flaps for Simultaneous Reconstruction of Total Nasal and Upper Lip Subunits: A Novel Approach to Complex Facial Resurfacing.

Background Reconstruction of the central facial subunits is a complex and challenging task. In cases in which both the nasal and upper lip subunits are involved, a technique that can reconstruct both aesthetic units with tissue of similar color and texture from a single donor site will be ideal. In this article we present our experience with the bipedicled preexpanded forehead flap for simultaneous nasal and upper lip resurfacing. Patients and Methods Between January 2012 and January 2015 we used this technique in the simultaneous reconstruction of total nasal and upper lip subunits in five patients. All cases were for burns scar resurfacing. Results Good aesthetic results were achieved in each of our five cases to date and no complications were encountered. All donor sites closed primarily with aesthetically pleasing well-concealed linear scars. In all cases small modifications such as philtral shaping and further flap thinning were performed under local anesthesia between 6 and 12 months postoperatively Conclusion The preexpanded forehead flap provides an unparalleled color and texture match when it comes to facial resurfacing. When both total nasal and upper lip resurfacings are required, it is possible to achieve this in a single sitting from a single donor site by using a bipedicled preexpanded forehead flap.
