OBJECTIVES: To observe the clinical effect and safety of auricular point sticking combined with periocular needle-embedding therapy for pseudomyopia and prevention of true myopia. METHODS: A total of 269 children with pseudomyopia were randomized into an observation group (134 cases, 2 cases dropped out) and a control group (135 cases, 5 cases dropped out). In the control group, the healthy education was provided. In the observation group, besides the intervention as the control group, the auricular point sticking was delivered at gan (CO12 ), pi (CO13 ), xin (CO15 ) and yan (LO5 ) on one ear in each treatment, combined with periocular needle-embedding technique at bilateral Cuanzhu (BL 2), Yuyao (EX-HN 4) and Sibai (ST 2)...

Temporomandibular joint internal disorders commonly present with limited mouth opening and pain. Treatment options range from invasive surgical procedures to minimally invasive interventions. This technical note aims to introduce a modification to the arthrocentesis technique in which a pressure infusion cuff (VBM Classic Infusor, Medizintechnik GmbH, Germany) is used for irrigation instead of syringes or peristaltic pumps. A pressure infusion cuff (bag) is an inflatable bag with a hand pump and a sphygmomanometer that allows monitorization of the pressure, and it is intended to apply pressure on IV fluid bags to assist with rapid infusion of fluids...

Extensive unforested sandy areas on the margins of floodplains and riverbeds, formed by dunes, barchans, and accumulation berms, are a ubiquitous feature across northern Eurasia and Alaska. These dynamic landscapes, which bear witness to the complex Holocene and modern climatic fluctuations, provide a unique opportunity to study ecosystem evolution. Within this heterogeneous assemblage, active dunes, characterized by their sparse plant communities, contrast sharply with the surrounding taiga (boreal) forests, which characterize stabilized dunes...

Electron sources are crucial elements in diverse applications such as electron microscopes, synchrotrons, and free-electron lasers. Nanometer-sharp needle tips are electron emitters with the highest beam quality, yet for a single needle the current is limited. Combining the emission of multiple needles promises large current yields while preserving the individual emitters' favorable properties. We present an ultrafast electron source consisting of a lithographically fabricated array of sharp gold tips illuminated with 25 fs laser pulses...

The area of drug delivery systems has witnessed significant advancements in recent years, with a particular focus on improving efficacy, stability, and patient compliance. Transdermal drug delivery offers numerous benefits compared to conventional methods of drug administration through the skin. It helps in avoiding gastric irritation, hepatic first-pass metabolism, and gastric degradation of the drug. It bypasses the gastrointestinal tract, eliminating the risk of first-pass metabolism and allowing drugs to be administered without being affected by pH, enzymes, or intestinal bacteria...

Transdermal delivery of peptide drugs is almost impossible with conventional penetration enhancers because of epidermal barrier function. Microneedle (MN) patches can bypass the epidermal barrier and have been developed for trans- and intradermal delivery of peptide drugs and vaccines. However, dissolving MN patches are limited by low drug loading capacities due to their small size and admixture of drug and water-soluble excipients. Furthermore, few in vivo pharmacokinetic studies, especially in large animals such as pigs, have been performed to assess post-application systemic drug exposure...

Gene therapy is a powerful technology to deliver new genes to a patient for the treatment of disease, be it to introduce a functional gene, inactivate a toxic gene, or provide a gene whose product can modulate the biology of the disease. The delivery method for the therapeutic vector can take many forms, ranging from intravenous infusion for systemic delivery to direct injection into the target tissue. For neurodegenerative disorders, it is often desirable to skew transduction towards the brain and/or spinal cord...

BACKGROUND AND AIMS: A three-dimensional electroanatomic mapping system-guided transseptal puncture (3D-TSP), without fluoroscopy or echocardiography, was insufficiently reported. Indications for 3D-TSP remain unclear. This study aimed to establish a precise technique and create a workflow for validating and selecting eligible patients for fluoroless 3D-TSP. METHODS AND RESULTS: We developed a new methodology for 3D-TSP based on the unipolar electrogram derived from transseptal needle tip (UEGM-tip) in 102 cases (the derivation cohort) with intracardiac echocardiography (ICE) from March 2018 to February 2019...

BACKGROUND AND AIMS: This pilot study aimed to evaluate safety and tissue sampling from subepithelial lesions (SEL) in the upper gastrointestinal tract with a novel electric motor driven endoscopic ultrasonography (EUS)-guided 17-gauge (G) size core needle biopsy (CNB) instrument. METHODS: An investigator-led prospective open label, performance and safety control study, including seven patients (female n  = 4, median 71 y, range 28-75) with a determined SEL (median size 30 mm, range 17-150 mm) in the upper digestive tract (stomach n  = 6, duodenum n  = 1) were eligible and later followed up 14 days after index procedure...

BACKGROUND/PURPOSE: Dry needling therapy and acupuncture can effectively relieve myofascial pain in temporomandibular disorders (TMDs). This study evaluated dental students' satisfaction with the "needling therapies for TMDs" lectures given in 2022 and 2023. MATERIALS AND METHODS: The "needling therapies for TMDs" lectures included mainly a dry needling therapy lecture and an acupuncture lecture which were given to the fifth-year dental students in both 2022 and 2023...

UNLABELLED: Traumatic brain injury (TBI) is an established risk factor for developing neurodegenerative disease. However, how TBI leads from acute injury to chronic neurodegeneration is limited to post-mortem models. There is a lack of connections between in vitro and in vivo TBI models that can relate injury forces to both macroscale tissue damage and brain function at the cellular level. Needle-induced cavitation (NIC) is a technique that can produce small cavitation bubbles in soft tissues, which allows us to relate small strains and strain rates in living tissue to ensuing acute and chronic cell death, tissue damage, and tissue remodeling...

Breast cancer is a substantial source of morbidity and mortality worldwide. It is particularly more difficult to treat at later stages, and treatment regimens depend heavily on both staging and the molecular subtype of the tumor. However, both detection and molecular analyses rely on standard imaging and histological method, which are costly, time-consuming, and lack necessary sensitivity/specificity. The estrogen receptor (ER) is, along with the progesterone receptor (PR) and human epidermal growth factor (HER-2), among the primary molecular markers which inform treatment...

BACKGROUND: Despite the common use of ultrasound (US)-guided fine-needle aspiration (FNA) for axillary node (AN) in breast cancer patients, only a limited number of studies are available regarding the diagnostic performance of AN-FNA according to the suspicion level based on US findings. This study compares the outcomes of US-guided AN-FNA in breast cancer patients, differentiating between those undergoing staging and surveillance. METHODS: A cross-sectional retrospective study with retrospective analysis was conducted on 767 consecutive AN-FNA procedures performed in 2017 at Samsung Medical Center in Seoul, with 654 for staging and 113 for surveillance in breast cancer patients...

BACKGROUND: The preoperative pathological diagnosis of rectal lesions is crucial for formulating treatment plans. For subepithelial lesions (SELs) and larger lesions with necrosis of the rectum, endoscopic forceps biopsy (EFB) cannot provide an accurate pathological diagnosis in most cases. By comparing the efficacy and safety of transrectal contrast-enhanced ultrasound-guided transperineal core-needle biopsy (TRCEUS-TP-CNB) and EFB, this study explored the value of TRCEUS-TP-CNB in the diagnosis of complex rectal lesions, such as SELs...

Sarcoidosis is a multisystemic granulomatous disease that is frequently localized in the lungs and lymph nodes. We herein report a case of pulmonary sarcoidosis secondary to shin'iseihaito administration. During remission with 5 mg prednisolone/day of maintenance treatment, chest computed tomography revealed a mass in the left lower lobe with re-enlarged bilateral hilar/mediastinal lymph nodes. Transbronchial lung biopsy of the mass and endobronchial ultrasound-guided transbronchial needle aspiration of mediastinal lymph nodes revealed adenocarcinoma and noncaseating granulomas, respectively...

The investigation of antigen-laden droplet deposition patterns on antibody-immobilized substrates has potential for disease detection. Stationary droplets that contain antigens on surfaces immobilized with antibodies can function as microreactors. Temperature modulation enhances reaction efficiency and reduces detection time in droplet-based systems. Thus, the aim of this study is to explore the impact of substrate heating on the structures of protein deposits and the influence of substrate temperature on thermo-solutal Marangoni convection within the droplets...

We report the first case of pancreatic stent (PS) migration placed early into the main pancreatic duct (MPD) during endoscopic retrograde cholangiopancreatography (ERCP) due to subsequent endoscopic papillary balloon dilation. A 74-year-old woman who complained of fever and abdominal pain was diagnosed with acute calculous cholangitis. On ERCP, a needle-knife precut papillotomy was performed from the orifice because of difficult cannulation. Because of unintentional guidewire insertion into the MPD from the orifice, a PS with bilateral flaps was promptly placed to prevent post-ERCP pancreatitis...

Extragonadal germ cell tumors (GCTs) are challenging to diagnose. We present a case of suprarenal GCT, with hepatic infiltration where differential diagnosis included neuroblastoma and hepatoblastoma. The positive positron emission tomography scan further obfuscated the situation. The diagnosis was clinched by fine-needle aspiration cytology and cell block immunohistochemistry.
