OBJECTIVE: Body mass index (BMI) is known to contribute to outcomes for patients with knee OA. Furthermore, BMI influences the protein expression of orthobiologic treatments like platelet-rich plasma (PRP) and microfragmented adipose tissue (MFAT). We performed a secondary analysis of the association of BMI with PROs for patients with knee OA who received either PRP or MFAT injections. METHODS: Seventy-one patients with knee OA were randomized to receive a single ultrasound-guided injection of PRP or MFAT...

The purpose of preoperative biliary drainage (PBD) is to reduce complications during the perioperative period. The extrahepatic bile duct comprises distal and hilar bile ducts and assessing the need for PBD must be considered separately for each duct, as surgical procedures and morbidities vary. The representative disease-causing distal bile duct obstruction is pancreatic cancer. A randomized controlled trial has revealed that PBD carries the risk of recurrent cholangitis and pancreatitis before surgery, thus eliminating the need for PBD when early surgery is feasible...

Introduction . Strongyloides stercoralis causes a helminthic infection that occurs via penetration of the skin with migration to the bloodstream, tracheobronchial tree, and gastrointestinal system. Pulmonary manifestations are rare and are typically seen in immunosuppressed patients who have Strongyloides stercoralis hyperinfection syndrome. Eosinophilic pleural effusions are rare in strongyloidiasis and only cited in a few case reports. Case Presentation . A 45-year-old male with a past medical history of diabetes mellitus, alcoholic cirrhosis, and end-stage renal disease presented to the emergency department with abdominal pain and dyspnea...

AIM: Comprehensive genomic profiling (CGP) test for solid tumors is now increasingly utilized in clinical practice, especially in pancreatobiliary cancer, and specimens obtained by endoscopic ultrasound-guided tissue acquisition (EUS-TA) are often submitted for tissue-based CGP test. In this study, we evaluated the feasibility of EUS-TA using a 22-gauge Franseen needle for the CGP test. METHODS: Consecutive patients with solid tumors who underwent EUS-TA using a 22-gauge Franseen needle, and whose tissue samples were pre-checked for suitability for CGP test, were included in this single-center, retrospective analysis...

BACKGROUND: Endobronchial ultrasound-guided transbronchial cryobiopsy (EBUS-cryobiopsy) is advantageous for collecting larger specimens with minimal crushing; however, it has not been widely used for mediastinal tumors. CASE PRESENTATION: A 73-year-old woman with a history of left breast cancer underwent surgery followed by radiotherapy. Computed tomography showed a mass in the anterior mediastinum that was in extensive contact with the sternum on the ventral side and partly with the trachea on the dorsal side...

We report the case of a young, immunocompetent, non-pregnant woman diagnosed with acute abdomen 3 weeks after an ultrasound-guided transvaginal oocyte retrieval (TVOR). Peritoneal fluid, obtained during exploratory laparoscopy, yielded Mycoplasma hominis as the sole pathogen. The patient's symptoms and signs improved after 24-hour treatment with intravenous clindamycin, ampicillin and gentamycin. Complete resolution was achieved with oral doxycycline for 14 days.

BACKGROUND: Gluteal fat grafting is a common procedure in liposculpture. This study proposes a Doppler ultrasound-guided intramuscular and subcutaneous gluteal lipotransfer technique that allows for visualization of the location of the gluteal vessels, avoiding approaching them during lipotransfer by having the cannula localized during fat infiltration. METHODS: This new technique was applied to 24 women after obtaining informed consent and providing them with a clear explanation of potential risks and complications...

Superior vena cava obstruction (SVCO) is an oncological emergency and can often be linked to an underlying lung malignancy. Due to the potential life-threatening risks associated with SVCO, it necessitates urgent diagnosis and management. In this report, we discuss 3 case studies where the use of ultrasound-guided supraclavicular lymph node biopsy was used to obtain a biopsy from patients with SVCO, followed by rapid on-site evaluation (ROSE). The benefits of this technique ensure a more rapid histological diagnosis, while also involving a less invasive procedure for the patient...

INTRODUCTION: Hip fractures cause severe pain during positioning for spinal anesthesia (SA). Intravenous systemic analgesics can lead to various complications in elderly patients, hence peripheral nerve blocks are emerging as a standard of care in pain management for hip fractures, among which femoral nerve block (FNB) is widely known and practiced. Pericapsular nerve group (PENG) block is a recently described technique that blocks the articular nerves of the hip with motor-sparing effects and is used to manage positional pain in hip fractures...

BACKGROUND: Small-bore chest drains are now the most common drains for treating pleural effusion (PE), but knowledge on complications is limited especially in malignant PE and empyema. We aimed to evaluate rate of complications of ultrasound guided small bore chest drains [6-10 French (F)] by PE etiology. METHODS: Retrospective cohort study of 484 chest drains inserted in 330 adults in a Swedish department 2018-2020. Rate of complications (blockage, dislocation, infection, or misplacement) and repeat intervention (new drain within 2 weeks or surgery) was analyzed by effusion type (organ failure, parapneumonic, malignant, empyema, other, unknown), age, sex, seniority of radiologist, and bore size using multivariable logistic regression...

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...

BACKGROUND: Radiofrequency ablation of genicular nerves is recommended to ameliorate the pain of osteoarthritis of the knee. However, long-term efficacy in patients with persistent pain following total knee arthroplasty remains elusive. The current study aimed to evaluate radiofrequency ablation of genicular nerves using a hybrid technique to manage severe incapacitating pain and quality of life following surgery. METHODS: This prospective, observational study included patients suffering from intractable knee pain with scores > 4 on the Numeric rating scale after 6 months of total knee arthroplasty...

BACKGROUND CONTEXT: Postoperative pain control following spine surgery can be difficult. The Enhanced Recovery After Surgery (ERAS) programs use multimodal approaches to manage postoperative pain. While an erector spinae plane block (ESPB) is commonly utilized, the ideal distance for injection from the incision, referred to as the ES (ESPB to mid-surgical level) distance, remains undetermined. PURPOSE: We evaluated the impact of varying ES distances for ESPB on Numerical Rating Scale (NRS) measures of postoperative pain within the ERAS protocol...

Adenoid cystic carcinoma (ACC), a rare malignancy, typically originates in salivary glands and is rarely found in other locations. In this case report, we describe a 54-year-old male patient who was presented to the Urology Department of Yantai Yuhuangding hospital with right-sided waist pain. The patient underwent percutaneous ultrasound-guided biopsies of lesions in the kidney and lung, which were histologically confirmed as primary adenoid cystic carcinoma of the lung and metastatic renal adenoid cystic carcinoma, respectively...

Deep gluteal syndrome (DGS) is caused by sciatic nerve entrapment. Because fascial entrapment neuropathies may occur in multiple locations, ultrasound-guided nerve hydrodissection is a key component of DGS treatment. In this study, we examined the clinical outcomes of patients with DGS undergoing ultrasound-guided sciatic nerve hydrodissection. A 10 mL mixture consisting of 5% dextrose, 0.2% lidocaine (Xylocaine), and 4 mg betamethasone (Rinderon) was used for nerve hydrodissection. Clinical outcomes were evaluated using Numeric Rating Scale (NRS) scores of pain, the proportion of patients with favorable outcomes (reduction of ≥50% in pain), the duration for which patients exhibited favorable outcomes (percentage of follow-up duration), and the occurrence of major complications and minor side effects...

To develop ultrasound-guided radiotherapy, we proposed an assistant structure with embedded markers along with a novel alternative method, the Aligned Peak Response (APR) method, to alter the conventional delay-and-sum (DAS) beamformer for reconstructing ultrasound images obtained from a flexible array. We simulated imaging targets in Field-II using point target phantoms with point targets at different locations. In the experimental phantom ultrasound images, image RF data were acquired with a flexible transducer with in-house assistant structures embedded with needle targets for testing the accuracy of the APR method...
