Purpose

To critically appraise and summarize the potential of linear and/or volumetric dimensions of the maxillary sinuses obtained with cone-beam and multi-slice computed tomography.

Methods

A bibliographic search was conducted in seven databases in August 2023. Cross-sectional retrospective studies using linear and volumetric measurements of the maxillary sinuses obtained with cone-beam and multi-slice computed tomography for sex estimation and presenting numerical estimation data were included. Narrative or systematic reviews, letters to the editor, case reports, laboratory studies in animals, and experimental studies were excluded. The critical appraisal and certainty of evidence were assessed using the guidelines described by Fowkes and Fulton and GRADE, respectively.

Results

A total of 656 studies were found, 32 of which were included. A total of 3631 individuals were analyzed and the overall sex estimation rate ranged from 54.9 % to 95 %. When compared with isolated measurements, combined linear measurements of the right and left maxillary sinuses, such as width, length, and height, provided a higher rate of sex estimation (54.9–95 %). In most of the studies (62.5 %), all measurements were higher in men than in women. Multiple methodological problems were found in the studies, especially distorting influences in 84.4 % of the answers. The certainty of evidence varied from very low to low.

Conclusions

The combination of height, width, and length measurements of the right and left maxillary sinuses from cone-beam and multi-slice computed tomography can be useful in the estimation of sex of humans. Further primary studies are needed to increase the certainty of evidence.

Necrotizing Fasciitis (NF) is a severe life-threatening soft tissue infection characterized by the rapid destruction of muscle, fat and fascial layers. This report details an autopsy case report of a 40year old male, unclaimed body lacking the complete history except that given by the Police personnel accompanying in which there is no prior history of trauma. This person succumbed to septic shock secondary to NF, despite clinical interventions. This case emphasizes the importance of early diagnosis and the need for heightened clinical awareness to improve patient outcomes.

The primary objective of forensic investigation of a case is to recognize, identify, locate, and examine the evidence. Microscopy is a technique that provides crucial information for resolving a case or advancing the investigation process by analyzing the evidence obtained from a crime scene. It is often used in conjunction with suitable analytical techniques. Various microscopes are employed; scanning probe microscopes are available in diverse forensic analyses and studies. Among these, the atomic force microscope (AFM) is the most commonly used scanning probe technology, offering a unique morphological and physico-chemical perspective for analyzing multiple pieces of evidence in forensic investigations. Notably, it is a non-destructive technique capable of operating in liquid or air without complex sample preparation. The article delves into a detailed exploration of the applications of AFM in the realms of nanomechanical forensics and nanoscale characterization of forensically significant samples.

Sudden Cardiac Death (SCD) often shows negative anatomy results after a systemic autopsy and the gene mutations of potassium channel play a key role in the etiology of SCD. We established a feasible system to detect SCD-related mutations and investigated the mutations at KCNQ1 and KCNH2 genes in the Chinese population. We established a mutation detection system combined with multiplex PCR, SNaPshot technique, and capillary electrophoresis. We genotyped 101 putative mutations at KCNQ1 and KCNH2 genes in 60 SCD of negative anatomy and 50 controls using the established assay and compared Odd Ratio (OR). Four coding variants were identified in the KCNQ1 gene: S546S, I145I, P448R, and G643S. The mutations of I145I and S546S did not differ significantly in the SCD compared with controls. 21 SCD individuals (35 %) and 1 control individual (2 %) showed a genotype of C/G at P448R (OR = 17.5, 95 % CI [2.40–127.82]). 24 SCD individuals (40 %) and 1 control individual (2 %) showed a genotype of C/G at G643S (OR = 20.0, 95 % CI [2.75–145.25]). We established a robust assay for rapid screening the putative SCD-related mutations in KCNQ1 and KCNH2 genes. The new assay in our study is easily amenable to the majority of laboratories without the need for new specialized equipment. Our method will meet the increasing requirement of mutation screening for SCD in regular DNA laboratories and will help screen mutations in those dead of SCD and their relatives.

Analyzing skeletal remains is crucial for identifying individuals, and forensic anthropologists use this analysis to determine biological characteristics, particularly sex, aiding criminal investigations. Among thoracic vertebrae, the twelfth thoracic vertebra (T12) is highly sexually dimorphic in various populations. This study aims to establish a discriminant function equation (DFE) for sex determination based on T12 in the Central Thai population. A total of 15 parameters of T12 were examined in 69 bone samples (43 males and 26 females). Among the 15 parameters, 14 were significantly different between males and females. The discriminant function equation (DFE) was generated as DFE = −19.578 + 0.376(i) BDsm + 0.254(l) PW + 0.081TDm, with a cutoff value of −0.296 for males and females, showing 92.8 % accuracy. The evaluation of the DFE using 10 blind samples showed 90 % accuracy. These findings may offer an additional method for sex determination through T12, complementing the examination of other skeletal elements.

Forensic medicine in Palestine is a new branch of medicine compared with other medical specialties and is still at a nascent stage. Only 6 medical doctors specializing in forensic medicine are currently practicing in Palestine, including only one female specialist (the author). Palestine has adopted a system that combines clinical forensic medicine and forensic pathology. Forensic doctors can deal with both the living and the dead and deal with cases of physical and sexual assault, gender-based violence, and domestic violence.

In different courts, such as civil, military, and shariah, Palestinian judicial decisions depend primarily on forensic medical reports and the testimonies that forensic doctors provide for the court to explain their reports. Forensic medicine has a significant role and crucial impact on achieving justice for victims of all types of abuse, either dead or alive. However, the role of forensic medicine in achieving justice for victims, and hence fighting and eradicating violence, is underestimated and not fully understood by the general population.

This paper introduces to the reader the status of forensic medicine in Palestine, focusing on the challenges and obstacles faced by both the victims and forensic doctors. Meeting these challenges and overcoming obstacles is essential for fighting all types of violence, including violence against women in Palestinian society.

The current provision of forensic medical services in Palestine is less than satisfactory, being considerably hampered by the lack of legislation and regulations.

Palestine is in great need of continued international support for forensic medicine and forensic services. Two projects supported by the United Nations put the country on the road, but there are still many miles to go toward the aim.

Much has been written about bite mark comparisons and bite mark analysis. It has largely been written for, and remained within the domain of, the forensic odontologist despite the limited number of such specialists and the even smaller subset who have expertise in this area. For those health professionals who work in the field of clinical forensic medicine, most will not have access to a forensic odontologist. Courts can be reticent about the costs involved in obtaining another expert opinion. For health professionals, who will likely encounter more bite marks in their career than forensic odontologists, the difficulty is knowing what can legitimately be opined about such injuries.

Male rape is a relatively under-discussed topic in scientific literature, despite its significant relevance and prevalence worldwide, including in Brazil. To inform public health and safety policies, this study aimed to analyze cases of male rape using data from SINAN, the Information System for Notifiable Diseases, a division of the Brazilian Ministry of Health, for the years 2010–2022. Our findings reveal a 469 % increase in male rape cases in the country over the study period, with a predominance of cases in the state of São Paulo. Also, a higher prevalence of cases was observed among individuals aged 5–9 years. Furthermore, we identified a correlation between the occurrence of rape and certain factors, including individuals with less than 4 years of formal education if they were over the age of 50, and those who had a history of being sexually abused between the ages of 5 and 14. Additionally, this study reinforces the prevalence of rape cases occurring within domestic environments and perpetrated by individuals closely related to the victims. This study contributes to filling the gap in research on male rape in Brazil, laying the foundation for the development of strategies to prevent and combat rape in the country.
