In suboccipital craniectomy where the bone is not repositioned, there may be a significant cosmetic defect due to lack of skull bone in the suboccipital region. It may accompanied by sensory symptoms, including pain. To prevent any cosmetic defect and sensory symptoms we repositioned the bone chips at the craniectomy site in 42 suboccipital craniectomies before the closure of the scalp. At a mean follow-up of 22 months (range: 5-44 months), two patients complained of mild discomfort in the healed wound or of occasional local pain. One patient complained of mild itching at the site. In two patients, bone chips were accumulated at the lower part of the suboccipital craniectomy and failed to form a uniform bone cover at the operated site. In one patient, all bone chips were reabsorbed and there was no bone at the operated site. There was pseudomeningocele formation in one patient. In the rest of the cases there was satisfactory bone coverage at the operated site, both clinically and radiologically. The wound sites were aesthetically acceptable in 40 cases. Our study suggests that in the majority of cases where suboccipital craniotomy is not possible or not done, repositioning of the bone chips at the craniectomy site is associated with satisfactory aesthetic and functional outcome and formation of bone coverage at the operated site.

Acetylcholinesterase (AChE) and AChE inhibitors play critical roles in the early diagnosis and treatment of Alzheimer's disease (AD). Herein, a fluorescence/colorimetry/smartphone triple-mode sensing platform was constructed for both AChE activity monitoring and AChE inhibitor screening by exploring a Cu (I) compound, CuI (SR) (R = CHCHNH), as a fluorescent probe. In comparison of most other fluorescent probes, CuI (SR) presented exceptional stability against pH, temperature, UV irradiation, redox agents, and metal ions, as well as good recyclability due to its unique chemical structure.

DNA identification of human skeletal remains play a valuable role in the forensic field, especially in missing persons and mass disasters investigation. Hard tissues, such as bones and teeth, represent a very common kind of samples analyzed in forensic laboratories because often they are the only biological materials remaining. However, the major limitation in using these compact samples rely on time consuming and labor-intensive treatment of grinding them into powder before proceeding with the conventional DNA purification and extraction step.

Osteoclast cell image analysis plays a key role in osteoporosis research, but it typically involves extensive manual image processing and hand annotations by a trained expert. In the last few years, a handful of machine learning approaches for osteoclast image analysis have been developed, but none have addressed the full instance segmentation task required to produce the same output as that of the human expert led process. Furthermore, none of the prior, fully automated algorithms have publicly available code, pretrained models, or annotated datasets, inhibiting reproduction and extension of their work.

Background: Surgery for depressed skull fractures (DSFs) is always faced by multiple challenges including ideal timing, defect reconstruction and complications. Few data are available regarding the aesthetic results and patients' satisfaction following DSFs management.
Methods: A prospective non-randomized study included 59 traumatic brain injury (TBI) patients surgically treated for DSFs.
Article Synopsis
- The study aimed to compare the effectiveness of low-speed drilling versus conventional drilling in implant placement surgery, focusing on accuracy, procedure duration, and bone chip accumulation.
- There were no significant differences in accuracy between the two methods, but low-speed drilling resulted in longer procedure times and the collection of larger bone fragments.
- The findings suggest that while low-speed drilling doesn't compromise accuracy, it may offer benefits in terms of harvesting more substantial bone chips that could support healing, making it a viable alternative to conventional drilling.
