Objectives: The aim of this publication is to provide a concept for prevention and a standardized step-by-step clinical approach to this rare but serious and potentially preventable complication of dental local anesthesia.
Materials And Methods: We collected data with a PUBMED search using the key words "local anesthesia," "dental anesthesia/anesthesia" OR "mandibular block anesthesia," "complication," "hypodermic needle," "needle breakage" OR "needle fracture," and "foreign body AND removal" OR "retrieval." The existing literature was systematically evaluated from 1980 to date using Microsoft Excel 2007 (Microsoft Corporation).
Results: After analysis of the literature, we included 36 reports documenting 59 needle breakage events and defined possible risk factors and preventive measures. All relevant reported parameters were listed in tabular form. The main result of this article is a treatment algorithm for this complication.
Conclusions: Prevention of a needle fracture should be the main goal during local dental anesthesia. Use of longer hypodermic needle can obviate complex retrieval surgery. If immediate removal of the fragment fails, localization, planning, and the necessary surgical procedure should be arranged promptly.
Clinical Relevance: Following a strict algorithm, successful surgical handling of this complication will depend on minimizing risk and following treatment recommendations closely.

Granular hydrogels are injectable and inherently porous biomaterials assembled through the packing of microparticles. These particles typically have a symmetric and spherical shape. However, recent studies have shown that asymmetric particles with high aspect ratios, such as fibers and rods, can significantly improve the mechanics, structure, and cell-guidance ability of granular hydrogels.

Objectives: Drug-loaded mucoadhesive silk fibroin (SF) microneedle patch can overcome the limitations of low bioavailability and significant pain associated with traditional treatment methods, such as topical application or injection of triamcinolone for oral submucous fibrosis (OSF). However, these systems release the drug too quickly, failing to meet the clinical requirements. This study aims to construct a mucoadhesive SF microneedle patch pre-assembled with silk fibroin nanospheres (SFN) and explore its ability to sustain the release of triamcinolone in the treatment of OSF.

Purpose Of The Study: Open (incisional) biopsies have long been accepted as the gold standard in diagnosing bone and soft tissue tumors. However, the main disadvantage of this method is that it can lead to increased contamination, hematoma, infection, and pathological fracture. Compared to open biopsies, percutaneous core needle biopsies are less invasive, do not require hospitalization, have low costs and low complication rates, and there is no need for wound healing in cases that require radiotherapy.

Flail chest is a life-threatening condition characterized by multiple rib fractures that result in a partially free rib cage. Thoracic paravertebral block (TPVB) allows visualization of the needle tip under ultrasound guidance and can be safely performed, unlike epidural anesthesia where the needle tip cannot be visualized. Here, we describe a case of flail chest in whom TPVB was used, as it provides the same level of analgesia as epidural anesthesia and has a perfect analgesic effect.

Objective: To observe the effects of the "Zhibian" (BL54)-toward-"Shuidao" (ST28) acupuncture on key regulatory factors during mitochondrial apoptosis of testicular tissue in asthenozoospermia mice, and explore the potential mechanism of the protective effect of acupuncture on reproductive function.
Methods: Thirty C57BL/6 male mice were randomly divided into a blank group, a model group and an acupuncture group, 10 mice in each group. In the model and the acupuncture groups, the intraperitoneal injection of cyclophosphamide (30 mg•kg•d) was delivered for 7 days to prepare the asthenozoospermia model.
