RESUMO
PURPOSE: To evaluate safety and effectiveness of percutaneous biliary endoscopy (PBE) performed on patients ineligible for surgery or endoscopic retrograde cholangiopancreatography. MATERIALS AND METHODS: Retrospective review was conducted for all patients who underwent PBE at a single academic institution between June 2013 and February 2020; 39 patients underwent 58 choledochoscopy sessions, and 21 patients underwent 48 cholecystoscopy sessions. Choledochoscopy indications included stone removal (23 of 39 patients) or biliary stenosis evaluation (19 of 39 patients). Cholecystoscopy indications included calculous cholecystitis (18 of 21 patients) and symptomatic cholelithiasis (3 of 21 patients). Technical success, procedural and fluoroscopy times, and tube-free survival were assessed. RESULTS: For all PBEs performed for stone clearance, using disposable endoscopes led to shorter mean ± SD procedural (128.7 minutes ± 56.2 vs 240.2 minutes ± 184.6; P < .01) and fluoroscopy times (10.7 minutes ± 7.9 vs 16.5 minutes ± 12.0; P = .01) than using reusable endoscopes. Increasing institutional experience was associated with reduced procedural time (ß = -56.73; P < .001). Choledochoscopy technical success was 94.8% with 1 adverse event of bile duct perforation with bile leak requiring drainage. For patients with choledocholithiasis, biliary drains were removed in 14 (60.9%) patients, with a mean tube-free survival of 22.1 months ± 23.8. For cholecystoscopy, technical success was 93.8% with no adverse events. Cholecystostomy tubes were removed in 15 (71.4%) patients, with a mean tube-free survival of 7.5 months ± 8.8. CONCLUSIONS: This study supports PBE as a safe and feasible option for nonsurgical patients or those with altered anatomy precluding endoscopic retrograde cholangiopancreatography. Moreover, PBE may result in tube-free survival.

Paget's disease of bone is a disorder of osteoclasts which hampers the physiological process of bone remodeling. It is the most common metabolic orthopedic disease in the Caucasian populace; we report the diagnosis of Paget's disease of bone in a South-Asian male in his early 50s with a history of gastrointestinal symptoms, weight loss and back pain. An alkaline phosphatase level of 1104 IU/L was noted. A 3-phase bone scan showed noncontiguous heterogenous nuclear uptake. After exhaustive evaluation, the patient was diagnosed with Paget's disease of bone. Despite the disease activity being mitigated by alendronate and monitored by ALP levels within normal range per protocol, the patient had compression fractures of the vertebrae requiring early reinitiation of oral bisphosphonates. This raised doubts about the efficacy of metabolic marker-based management in Paget's disease of bone.
RESUMO
OBJECTIVE: The aim of the study was to examine applications of cough sounds towards screening tools and diagnostics in the biomedical and engineering literature, with particular focus on disease types, acoustic data collection protocols, data processing and analytics, accuracy, and limitations. DATA SOURCES: PubMed, EMBASE, Web of Science, Scopus, Cochrane Library, IEEE Xplore, Engineering Village, and ACM Digital Library were searched from inception to August 2021. REVIEW METHODS: A scoping review was conducted on screening and diagnostic uses of cough sounds in adults, children, and animals, in English peer-reviewed and gray literature of any design. RESULTS: From a total of 438 abstracts screened, 108 articles met inclusion criteria. Human studies were most common (77.8%); the majority focused on adults (57.3%). Single-modality acoustic data collection was most common (71.2%), with few multimodal studies, including plethysmography (15.7%) and clinico-demographic data (7.4%). Data analytics methods were highly variable, with 61.1% using machine learning, the majority of which (78.8%) were published after 2010. Studies commonly focused on cough detection (41.7%) and screening of COVID-19 (11.1%); among pediatric studies, the most common focus was diagnosis of asthma (52.6%). CONCLUSION: Though the use of cough sounds in diagnostics is not new, academic interest has accelerated in the past decade. Cough sound offers the possibility of an accessible, noninvasive, and low-cost disease biomarker, particularly in the era of rapid development of machine learning capabilities in combination with the ubiquity of cellular technology with high-quality recording capability. However, most cough sound literature hinges on nonstandardized data collection protocols and small, nondiverse, single-modality datasets, with limited external validity.

PURPOSE: To evaluate the safety, technical success and short-term effectiveness of polyurethane-covered stent (PK Papyrus, BioTronik, Berlin) in the treatment of pulmonary arteriovenous malformations (PAVMs) that are not amenable to embolotherapy. MATERIALS AND METHODS: In this IRB-approved, retrospective study, data from patients who received polyurethane-covered stents for exclusion of PAVMs were analyzed. The study included 5 patients (all women) with a median age of 40 years (range 25-60). Patients presented with hypoxemia, TIAs, and/or epistaxis; 4 were confirmed to have HHT. All had multiple PAVMs diagnosed on chest CT and underwent embolization with other devices in addition to the polyurethane-covered stent. The indication for stent placement in all cases was a short and/or tortuous feeding artery. Safety was assessed by immediate or short-term complications, e.g., migration, stent thrombosis, and fracture. Technical success was defined as the ability to accurately place the stent at the intended location. Effectiveness was defined as successful exclusion of PAVM with no perfusion across the AVM. RESULTS: Technical success of stent placement was 100%. AVM exclusion rate was 80% after single stent deployment; in the case of incomplete exclusion, success was achieved using an overlapping stent to completely cover a second feeding artery. During the median follow-up period of 5 months (range 2-10), all stents remained patent, and AVMs were excluded without other complications. CONCLUSION: Exclusion of PAVMs with polyurethane-covered stents is technically feasible, safe, and shows short-term effectiveness for PAVMs with a short/tortuous feeding artery when traditional embolization techniques are not possible.

Gender-affirming surgery (GAS) is increasingly being performed. GAS is tailored to the patient leading to a diverse spectrum of radiologic post-operative findings. Radiologists who are unfamiliar with expected anatomic alterations after GAS may misdiagnose important complications leading to adverse patient outcomes. This collaborative multi-institutional review aims to: Describe relevant embryology and native anatomy. Describe relevant Gender-Affirming Surgery (GAS) techniques and expected neo-anatomy with associated complications, including common terminology. Review expected imaging appearance of neo-anatomy/postoperative findings. Review multi-modality [ultrasound, plain film, retrograde urethrogram, computed tomography] emergent imaging findings. Understand unique patient evaluation and imaging protocol considerations in the GAS population. Discuss pearls and pitfalls of imaging in the acute post-GAS setting.

The authors report a case of endobronchial migration of a POD packing coil following embolization of a pulmonary artery pseudoaneurysm in a patient with cavitary tuberculosis and its successful management by bronchoscopy-assisted removal of the coil. Coil migration may be secondary to continued cough and persistence of a bronchial to pulmonary artery fistula from tuberculous infection and inflammation.
RESUMO
Occult gastrointestinal bleeding (GIB) is a challenge for physicians to diagnose and treat. A systematic literature search of the PubMed and Embase databases was conducted up to January 1, 2023. Eligible studies included primary research studies with patients undergoing provocative mesenteric angiography (PMA) for diagnosis or localization of occult GIB. Twenty-seven articles (230 patients) were included in the review. Most patients (64.8%) presented with lower GIB. The average positivity rate for provocative angiography was 48.7% (58% with heparin and 46.7% in thrombolytics). Embolization was performed in 46.4% of patients, and surgical management was performed in 37.5%. Complications were rare. PMA can be an important diagnostic and treatment tool but studies with high-level evidence and standardized protocols are needed to establish its safety and optimal use.
RESUMO
Craniopharyngiomas emanate from squamous cell remnants in the hypophyseal/pharyngeal duct region. This report details the unprecedented case of a 29-year-old male with adamantinomatous craniopharyngioma, who, following a motor vehicle collision (MVC), presented with post-traumatic intratumoral hemorrhage leading to acute basal ganglia infarct. The patient, previously subjected to subtotal resection, exhibited focal neurological deficits attributed to compression of lenticulostriate arteries due to the sudden increase in tumor volume. The patient, ineligible for thrombolysis or thrombectomy, was conservatively managed post-MVC. Subtotal resection occurred four months later. After one year, persistent right-sided weakness (2/5 motor power) remained, and the recommended stereotactic radiotherapy was declined by the patient. Notably, this instance represents the first documented case of post-traumatic intratumoral hemorrhage in adamantinomatous craniopharyngioma. This report distinguishes between adamantinomatous and papillary subtypes, noting their prevalence in different age groups. While these tumors commonly present with gradual vision changes, fatigue, and endocrine dysfunction, complications such as intra-tumoral hemorrhage remain rare. This report serves as an educational tool, shedding light on potential complications and urging increased vigilance in managing craniopharyngiomas.
RESUMO
Spontaneous transvaginal small bowel evisceration is an extremely rare condition with a few more than 100 documented cases to date. The complications of such a rare entity revolve around its preoperative presentation as well as its operative and postoperative complications. The complications seen are intestinal incarcerations and perforations with an increased risk of post-surgical ileus and peritonitis in a time-dependent fashion. In our case, a postmenopausal female presented with sudden onset bowel evisceration through a defect in the posterior vaginal apex during straining for defecation. Past medical history was significant for intermittent abdominal pain, bloating, and chronic constipation. The patient had no signs of trauma, signs of sexual assault, preceding events, or prior urinary disturbances. The patient was treated surgically with laparotomy and bowel-packing followed by Ward-Mayo's repair with added on anterior and posterior colporrhaphy, and site-specific repair. Postoperatively, following a period of prolonged ileus, the patient made a full recovery. This case report aims to provide a better understanding of the mechanism and occurrence of such an event and also intends to raise awareness of this rare presentation as an emergency condition requiring prompt surgical management.
RESUMO
SARS-CoV-2 has had a lasting effect on the overall health of recovered patients, called 'long COVID'. Currently, there is a lack of a validated standard questionnaire to assess post-COVID health status. A retrospective observational study involving the recovered COVID patients admitted to a secondary care hospital in India between June to December 2020 (n = 123), was conducted using the EuroQol-5D-5L scale at discharge, 4 weeks and 8 weeks post-discharge. A significant difference in anxiety/depression scores was found (χ2 = 65.6, p < 0.000) among the 3 categories of time (discharge, 4 weeks and 8 weeks). The anxiety/depression dimension scores showed a significant change (p < 0.0001) between discharge and 8 weeks, using paired t-test. Age had a significant relationship with the anxiety/depression dimension at 4 weeks (OR = 5.617, 95% CI = 1.0320-30.5746, p < 0.05). A significant difference was found using Kruskal-Wallis rank-sum test on mean index scores (χ2 = 60.0, p < 0.000) among the three categories of time (discharge, 4 weeks and 8 weeks). There was a statistically significant difference of time on EQ Index scores as determined by one-way repeated measures ANOVA (F(2,375) = 18.941, p = <0.00001). Our study found time to have a statistically significant impact on the mean index scores, level sum scores and dimension scores. Smoking was found to be significantly associated with usual activity scores at 4 weeks. The most remarkable changes occurred in the anxiety/depression dimension. Overall, there was a general trend of health improvement.
