Purpose: We analyzed postoperative Frisby-Davis distance (FD2) stereotest scores and changes in the angle of deviation, and the correlation between postoperative FD2 stereotest scores and long-term surgical outcomes, in patients with intermittent exotropia. Methods: This retrospective study included patients aged less than 12 years with intermittent exotropia who underwent at least 28 months of postoperative follow-up. We analyzed the changes in the postoperative angle of deviation and preoperative and postoperative Titmus and FD2 stereotest scores. Surgical success rates at 28 months postoperatively were compared between the good (FD2 at 10 months postoperatively ≤ 10 arcsec) and bad (FD2 at 10 months postoperatively ≥ 15 arcsec) stereotest groups. Surgical success was defined as a horizontal deviation on distance measurement of 5 prism diopter (PD) esodeviation to 10 PD exodeviation at 1 year postoperatively. Results: This study included 101 patients. No significant difference was identified between preoperative and postoperative Titmus test scores. However, the FD2 stereotest scores were significantly improved at 10 months postoperatively (p = 0.001). A significant, positive correlation was observed between FD2 stereotest scores at 10 months postoperatively and the angles of deviation at distance at 10, 16, 22, and 28 months postoperatively (p ≤ 0.001 for all). The surgical success rates at 28 months postoperatively were 73.1% and 43.5% in the good and bad stereotest groups, respectively (p = 0.008). Conclusions Distance stereoacuity within 1 year postoperatively correlated with the postoperative angle of deviation at distance. Good distance stereoacuity (i.e., < 10 arcsec) within 1 year postoperatively correlated with a higher surgical success rate compared to bad distance stereoacuity.

Various complications following acupuncture have been reported. In most cases, complications occur from the close apposition of vital organs and acupuncture sites. These complications can be avoided if acupuncturists are trained in appropriate medical science such as anatomy. However, our case is somewhat different from the norm. The deceased received acupuncture on the abdomen, provided by an acupuncturist. Unexpected symptoms occurred suddenly and she was transported to a hospital where she died of hemoperitoneum. On the postmortem examination, a well-defined vascular tumor was identified on the front of the liver, which was also cirrhotic; a few localized injuries were identified on the cystic wall of the tumor and surrounding liver parenchyma. We assumed these injuries were complications of acupuncture. Therefore, we present this case to suggest that acupuncturists should be educated to be vigilant for complications following treatment to reduce the risk of these tragedies.

We present an unexpected fatal case of pulmonary embolism due to venous thrombosis after vaccination for coronavirus disease 2019 (ChAdOx1 nCov-19). The deceased was a 64-year-old woman with Alzheimer disease. The deceased had fever shortly after vaccination, and presented sudden dyspnea and died 8 days after vaccination. On postmortem examination, pulmonary embolism and venous thrombosis were noted in deep veins of both lower legs. Even though the psychomotor function of the deceased became fragile due to Alzheimer disease, the deceased was not bed-ridden, and major known risk factors related to venous thrombosis were not explicit in this case. Because there are not enough data related to vaccination and thrombosis, we hope that this case would be helpful in unraveling pathogenesis of venous thrombosis after vaccination and in determining whether there is any association between thrombosis and vaccination.

Compressive asphyxia is generally defined as a type of asphyxia caused by chest or abdominal compression by a heavy object. It has also been reported that it could be caused by external compression caused by ligatures around the chest or abdomen. However, asphyxia caused by ligature around the thorax has not been reported in suicide cases. We present an unusual case of suicide in which the cause of death was attributed to asphyxia caused by a ligature around the thorax. The deceased was a 41-year-old woman who was found dead and suspended by a rope around the thorax from a rooftop railing on the twelfth floor of a building. On postmortem examination, a ‘C’ shaped ligature mark was identified around the thorax, with a pressure mark in the subcutis and focal intramuscular hemorrhages, which were consistent with the ligature mark. The cause of death was determined to be asphyxia due to external compression of the chest in a suspended position.

This study presents a case of a patient who experienced sudden death due to fatal nitrite poisoning in the medical setting. It also highlights the pivotal role of postmortem examination in enhancing quality assurance in clinical medicine, as well as in providing resolutions for medicolegal disputes to all pertinent stakeholders, regarding the patient’s death. The patient was found dead during admission after orthopedic surgery. The death certificate was issued by the clinician attributing the cause of death to respiratory failure due to pulmonary embolism. This medical certification of death instigated medicolegal disputes, resulting in allegations of medical negligence or malpractice. Subsequently, a death investigation was initiated, and a postmortem examination confirmed nitrite poisoning as the cause of death. This medical evidence obtained from the autopsy could provide clarity in resolving medicolegal disputes surrounding the patient’s unexpected death in a medical setting. Moreover, a comprehensive review of all information obtained through a death investigation could offer valuable insights even for clinicians, as well as for patient’s family and other stakeholders. This includes guidance on certifying the cause of death based on varying levels of medical evidence and implementing preventive measures to enhance patient safety and mitigate the occurrence of unexpected death in the medical setting.

This case study highlights craniofacial identification technology (CFIT) as a complementary and translational tool for reconstruction of cranial gunshot wounds (GSWs) and presenting evidence beyond forensic identification. In forensic cases involving GSWs, a visual demonstration of the bullet trajectory can improve communication between forensic pathologists and non-medical judicial agencies and the court. Postmortem computed tomography (PMCT) images and autopsy images are essential medical evidence, providing a robust visual display of the GSW and its bullet trajectory. PMCT images are useful for identifying the precise projectile localization and characteristics of bone fractures. However, PMCT images may not adequately present soft tissue injuries well, and autopsy images can be unpleasant to non-medical professionals, making it difficult for them to understand such specialized scientific evidence. CFIT is a well-established scientific tool with which forensic experts in craniofacial identification can create more advanced reconstructed three-dimensional (3D) images based on both postmortem findings and PMCT data. Intracranial bullet trajectory can be shown simply and directly in reconstructed 3D cranial images. CFIT can serve as an adjunctive tool to overcome the limitations of both PMCT images and autopsy images, thereby facilitating better understanding of such specialized medical evidence by non-medical professionals. Here, we present two cases of head GSWs, in which CFIT was newly implemented to reconstruct the cranial GSW including bullet trajectory, for evidence presentation—expanding its traditional use in forensic identification. Therefore, CFIT can help provide better forensic medical services for non-medical professionals.

Exhumation in clandestine graves has to be done very carefully, since it is considered as a crime scene. Most such cases are related to a suspicious death and it is very important to search for human remains carefully. Before excavation, all operational procedures have to be planned in advance. Missing evidence or human errors can be avoided if each investigative team member works together with archaeological assistance and forensic pathologists. But in practice, it may be difficult to work according to established standard operational procedures because, in many cases, the clandestinely buried victims appear in unexpected areas or it is hard to locate the exact location of the site. Therefore, we present the following cases and hope that the general principles for exhuming a clandestine grave will be established so that they can be helpful in similar investigations in the future.
