RESUMEN

BACKGROUND: Skin's exposure to intrinsic and extrinsic factors causes age-related changes, leading to a lower amount of dermal collagen and elastin. AIM: This study investigated the effects of a novel facial muscle stimulation technology combined with radiofrequency (RF) heating on dermal collagen and elastin content for the treatment of facial wrinkles and skin laxity. METHODS: The active group subjects (N = 6) received four 20-min facial treatments with simultaneous RF and facial muscle stimulation, once weekly. The control subject (N = 1) was untreated. Skin biopsies obtained at baseline, 1-month and 3-month follow-up were evaluated histologically to determine collagen and elastin fibers content. A group of independent aestheticians evaluated facial skin appearance and wrinkle severity. Patient safety was followed. RESULTS: In the active group, collagen-occupied area reached 11.91 ± 1.80 × 106 µm2 (+25.32%, p < 0.05) and 12.35 ± 1.44 × 105 µm2 (+30.00%, p < 0.05) at 1-month and 3-month follow-up visits. Elastin-occupied area at 1-month and 3-month follow-up was 1.64 ± 0.14 × 105 µm2 (+67.23%, p < 0.05), and 1.99 ± 0.21 × 105 µm2 (+102.80%, p < 0.05). In the control group, there was no significant difference (p > 0.05) in collagen and elastin fibers. Active group wrinkle scores decreased from 5 (moderate, class II) to 3 (mild, class I). All subjects, except the control, improved in appearance posttreatment. No adverse events or side effects occurred. CONCLUSION: Decreased dermal collagen and elastin levels contributes to a gradual decline in skin elasticity, leading to facial wrinkles and unfirm skin. Study results showed noticeable improvement in facial appearance and increased dermal collagen and elastin content subsequent to simultaneous, noninvasive RF, and facial muscle stimulation treatments.

RESUMEN

PURPOSE: This study aimed to assess the clinical outcome and safety of holmium laser enucleation of the prostate (HoLEP) following transrectal ultrasound-guided prostate biopsy (TR biopsy) in the treatment of benign prostate hyperplasia. MATERIALS AND METHODS: We retrospectively analyzed data from 556 patients who underwent HoLEP between 2014 and 2021. The patients were categorized into six groups: Group 1-A (n=45) underwent HoLEP within four months post TR biopsy. Group 1-B (n=94) underwent HoLEP more than four months post TR biopsy. Group 1-C (n=120) underwent HoLEP after a single TR biopsy. Group 1-D (n=19) underwent HoLEP after two or more TR biopsies. Group 1-total (n=139, group 1-A+group 1-B or group 1-C+group 1-D) underwent HoLEP post TR biopsy. Group 2 (control group, n=417) underwent HoLEP without prior TR biopsy. We examined perioperative parameters, safety, and functional outcomes. RESULTS: The age, body mass index, International Prostate Symptom Score (IPSS), uroflowmetry, and comorbid diseases between group 1-total and group 2 were comparable. However, group 1-total exhibited significantly elevated prostate-specific antigen levels and larger prostate volumes (p<0.01). Perioperative factors like enucleation time, enucleation weight, and catheterization duration were notably higher in group 1-total (p<0.01). All groups showed significant improvements in IPSS, postvoid residual urine, and maximum flow rate during the 1-year postoperative period (p<0.05). The rates of postoperative complications were similar between group 1-total and group 2. CONCLUSIONS: Enucleation time and catheterization duration were significantly longer in the TR biopsy group. However, postoperative complications were not significantly different between TR biopsy and non-TR biopsy groups.

RESUMEN

PURPOSE: Percentage of positive cores involved on a systemic prostate biopsy has been established as a risk factor for adverse oncologic outcomes and is a National Comprehensive Cancer Network (NCCN) independent parameter for unfavorable intermediate-risk disease. Most data from a radiation standpoint was published in an era of conventional fractionation. We explore whether the higher biological dose delivered with SBRT can mitigate this risk factor. METHODS: A large single institutional database was interrogated to identify all patients diagnosed with localized prostate cancer (PCa) treated with 5-fraction SBRT without ADT. Pathology results were reviewed to determine detailed core involvement as well as Gleason score (GS). High-volume biopsy core involvement was defined as ≥ 50%. Weighted Gleason core involvement was reviewed, giving higher weight to higher-grade cancer. The PSA kinetics and oncologic outcomes were analyzed for association with core involvement. RESULTS: From 2009 to 2018, 1590 patients were identified who underwent SBRT for localized PCa. High-volume core involvement was a relatively rare event observed in 19% of our cohort, which was observed more in patients with small prostates (p < 0.0001) and/or intermediate-risk disease (p = 0.005). Higher PSA nadir was observed in those patients with low-volume core involvement within the intermediate-risk cohort (p = 0.004), which was confirmed when core involvement was analyzed as a continuous variable weighted by Gleason score (p = 0.049). High-volume core involvement was not associated with biochemical progression (p = 0.234). CONCLUSIONS: With a median follow-up of over 4 years, biochemical progression was not associated with pretreatment high-volume core involvement for patients treated with 5-fraction SBRT alone. In the era of prostate SBRT and MRI-directed prostate biopsies, the use of high-volume core involvement as an independent predictor of unfavorable intermediate risk disease should be revisited.

RESUMEN

An early-adolescent girl presented with incoordination, headache, vomiting and dysphonia. MRI brain demonstrated diffuse increased T2 and FLAIR signal in bilateral thalami, consistent with anaplastic astrocytomas. A stereotactic burr-hole biopsy provided frozen tissues sections demonstrating an IDH-1 wildtype astrocytoma (anaplastic grade III according to prior WHO classification 2016-21). Chemoradiotherapy was commenced. Bilateral thalamic high-grade astrocytomas are very rare in the paediatric population and require timely diagnosis and interdisciplinary management. CT and MR imaging help point towards this diagnosis in the correct clinical context.

RESUMEN

INTRODUCTION AND METHODS: Prostate biopsy (PB) is an essential step in the diagnosis and active surveillance of prostate cancer (PCa). Transperineal PB (TP-PB) is now the recommended approach and is mostly conducted under local anesthesia. However, this procedure can potentially cause anxiety for patients, given the oncological context and the fear of peri-procedural pain and complications. The objective of this narrative review is to summarize the currently available tools for the management of peri-interventional anxiety during TP-PB, with a particular emphasis on the potential role of virtual reality (VR) in this setting. RESULTS: In TP-PB, preoperative anxiety can lead to increased pain perception, longer procedure time, and decreased patient satisfaction. Pharmacological and non-pharmacological approaches have been explored to reduce anxiety, such as premedication, deep sedation, education, relaxation techniques, hypnosis, and music therapy, albeit with mixed results. VR has recently emerged in the technological armamentarium for managing pain and anxiety, and the efficiency of this technology has been evaluated in various medical fields, including pediatrics, gastroenterology, urology, gynecology, and psychiatry. CONCLUSION: Despite the paucity of available data, VR appears to be a safe and effective technique in reducing anxiety in many procedures, even in frail patients. No studies have evaluated the role of VR in TP-PB. Future research should thus explore the optimal way to implement VR technology and any potential benefits for TP-PB patients.

RESUMEN

Liver diseases of various etiologies are becoming increasingly common in the pediatric population. So far, the gold diagnostic standard in these disorders is liver biopsy. This procedure is invasive, painful and requires general anesthesia in this group of patients. Due to the continuous development of new research techniques, such as liver elastography, it is necessary to evaluate them in the context of their diagnostic usefulness. Ultrasound elastography, as a quick and effective method, is being used more and more often in the assessment and monitoring of liver dysfunction in both adults and children. There are several techniques of liver elastography, such as transient elastography, shear wave elastography consisting of various subtypes such as two-dimensional shear wave elastography, acoustic radiation force impulse and point shear wave elastography, which differ in terms of the measurement technique and the achieved results. The purpose of our review was to determine whether techniques of liver elastography could replace liver biopsy. Although now, based on the analyzed papers, elastography cannot replace liver biopsy, in our opinion, the role of this tool in monitoring pediatric patients with liver diseases will grow in the coming years.

RESUMEN

OBJECTIVE: Out-patient channelled endoscopic local anaesthetic biopsy reduces the time to diagnosis and wider use may improve cancer pathway times. This study aimed to assess the practice of ENT surgeons using channelled local anaesthetic biopsy. METHOD: A survey was distributed nationally, containing questions about out-patient local anaesthetic biopsy. RESULTS: In total, 58 responses were returned; only 12 per cent of respondents (n = 7) used general anaesthetic biopsy. The advantages of local anaesthetic biopsy were: the avoidance of general anaesthetic for patients with poor performance scores (95 per cent, n = 55) and faster cancer pathway times (91 per cent, n = 53). Disadvantages were: clinics running late (29 per cent, n = 17) and complications (24 per cent, n = 14). The main barrier to using local anaesthetic was access to channelled flexible endoscopy (38 per cent, n = 22), with 43 per cent (n = 25) reporting they were not using out-patient channelled endoscopes but would be interested in using them. CONCLUSION: Surgeons are interested in using channelled endoscopic local anaesthetic biopsy, but they are limited by access to equipment. Increased use of channelled endoscopes may improve national cancer pathway times and avoid challenging general anaesthetics.

RESUMEN

INTRODUCTION: Local anesthetics with adrenaline are widely used in routine practice and have long proven their benefits and safety. The rare complications due to their use mainly concern immuno-allergic and vascular mechanisms. DESCRIPTION: In this article, we present four similar cases of early transfixing skin necrosis occurring after radioguided breast biopsy under local anesthesia using epinephrine local anesthetics in the context of a diagnostic approach to breast cancer. DISCUSSION: Although the literature is comforting about the use of local anesthetics, even on the extremities, severe skin complications continue to be reported sporadically. The analysis and understanding of these phenomena would allow, in the long run, to avoid them and to reduce their importance. CONCLUSION: The occurrence of skin necrosis after breast biopsy under radiographic control is rare and seems to be related to the local anesthetic procedure. Although similar cases have been reported in the literature, it does not seem possible today to conclude on the exact physiopathology of these complications. A better knowledge of the pathophysiology of these complications would help to avoid their occurrence in the future.

RESUMEN

Contrast-enhanced MRI is the method of choice for brain tumor diagnostics, despite its low specificity for tumor tissue. This study compared the contribution of MR spectroscopic imaging (MRSI) and amino acid PET to improve the detection of tumor tissue. Methods: In 30 untreated patients with suspected glioma, O-(2-[18F]fluoroethyl)-l-tyrosine (18F-FET) PET; 3-T MRSI with a short echo time; and fluid-attenuated inversion recovery, T2-weighted, and contrast-enhanced T1-weighted MRI were performed for stereotactic biopsy planning. Serial samples were taken along the needle trajectory, and their masks were projected to the preoperative imaging data. Each sample was individually evaluated neuropathologically. 18F-FET uptake and the MRSI signals choline (Cho), N-acetyl-aspartate (NAA), creatine, myoinositol, and derived ratios were evaluated for each sample and classified using logistic regression. The diagnostic accuracy was evaluated by receiver operating characteristic analysis. Results: On the basis of the neuropathologic evaluation of tissue from 88 stereotactic biopsies, supplemented with 18F-FET PET and MRSI metrics from 20 areas on the healthy-appearing contralateral hemisphere to balance the glioma/nonglioma groups, 18F-FET PET identified glioma with the highest accuracy (area under the receiver operating characteristic curve, 0.89; 95% CI, 0.81-0.93; threshold, 1.4 × background uptake). Among the MR spectroscopic metabolites, Cho/NAA normalized to normal brain tissue showed the highest diagnostic accuracy (area under the receiver operating characteristic curve, 0.81; 95% CI, 0.71-0.88; threshold, 2.2). The combination of 18F-FET PET and normalized Cho/NAA did not improve the diagnostic performance. Conclusion: MRI-based delineation of gliomas should preferably be supplemented by 18F-FET PET.

RESUMEN

OBJECTIVE: We present a low-cost and easily accessible adaptation system to perform stereotactic procedures in infants. METHODS: We used an adaptive device consisting of a headband with a plaster bandage, cotton bandage roll, and gauze bandages. Prior to its clinical application, the device was tested in our neuroscience laboratory using a simulation model of a size similar to that of a 5-month-old infant, during which no complications arose. The headband cast technique was subsequently reproduced in a 5-month-old patient, serving as a fixation point for the placement of a Micromar frame for biopsy of a thalamic lesion. RESULTS: A stereotactic biopsy was successfully performed in a 5-month-old patient using a headband cast to secure the stereotactic frame. This method enabled precise targeting of the selected site, resulting in a histopathological diagnosis without any associated complications. CONCLUSIONS: The adaptive device is safe, easily accessible, and reproducible, facilitating the performance of stereotactic diagnostic procedures in infants, accurately reaching the planned objective without causing injuries or additional complications.

RESUMEN

PURPOSE: Reducing time between cancer screening, diagnosis, and initiation of treatment is best achieved when services are available in the same hospital. Yet, comprehensive cancer centers are typically unavailable in low- and middle-income countries (LMICs), where resources are limited and services scattered. This study explored the impact of establishing an in-house pathology laboratory at the largest public cancer hospital in Tanzania on the downstaging of cervical cancer. METHODS: We examined clinical datasets of 8,322 cervical cancer patients treated at the Ocean Road Cancer Institute (ORCI). The first period included patients treated from 2002 to 2016, before establishment of the pathology laboratory at ORCI; the second period (post-pathology establishment) included data from 2017 to 2020. Logistic regression analysis evaluated the impact of the pathology laboratory on stage of cervical cancer diagnosis. RESULTS: Patients treated during the post-pathology period were more likely to be clinically diagnosed at earlier disease stages compared to patients in the pre-pathology period (pre-pathology population diagnosed at early disease stage: 44.08%; post-pathology population diagnosed at early disease stage: 59.38%, p < 0.001). After adjustment for age, region of residence, and place of biopsy, regression results showed patients diagnosed during the post-pathology period had higher odds of early stage cervical cancer diagnosis than patients in the pre-pathology period (OR 1.35, 95% CI (1.16, 1.57), p < 0.001). CONCLUSIONS: Integrated and comprehensive cancer centers can overcome challenges in delivering expedited cervical cancer diagnosis and treatment. In-house pathology laboratories play an important role in facilitating timely diagnosis and rapid treatment of cervical and possibly other cancers in LMICs.

RESUMEN

PURPOSE: Less invasive decision support tools are desperately needed to identify occult high-risk disease in men with prostate cancer (PCa) on active surveillance (AS). For a variety of reasons, many men on AS with low- or intermediate-risk disease forgo the necessary repeat surveillance biopsies needed to identify potentially higher-risk PCa. Here, we describe the development of a blood-based immunocyte transcriptomic signature to identify men harboring occult aggressive PCa. We then validate it on a biopsy-positive population with the goal of identifying men who should not be on AS and confirm those men with indolent disease who can safely remain on AS. This model uses subtraction-normalized immunocyte transcriptomic profiles to risk-stratify men with PCa who could be candidates for AS. MATERIALS AND METHODS: Men were eligible for enrollment in the study if they were determined by their physician to have a risk profile that warranted prostate biopsy. Both training (n = 1017) and validation cohort (n = 1198) populations had blood samples drawn coincident to their prostate biopsy. Purified CD2+ and CD14+ immune cells were obtained from peripheral blood mononuclear cells, and RNA was extracted and sequenced. To avoid overfitting and unnecessary complexity, a regularized regression model was built on the training cohort to predict PCa aggressiveness based on the National Comprehensive Cancer Network PCa guidelines. This model was then validated on an independent cohort of biopsy-positive men only, using National Comprehensive Cancer Network unfavorable intermediate risk and worse as an aggressiveness outcome, identifying patients who were not appropriate for AS. RESULTS: The best final model for the AS setting was obtained by combining an immunocyte transcriptomic profile based on 2 cell types with PSA density and age, reaching an AUC of 0.73 (95% CI: 0.69-0.77). The model significantly outperforms (P < .001) PSA density as a biomarker, which has an AUC of 0.69 (95% CI: 0.65-0.73). This model yields an individualized patient risk score with 90% negative predictive value and 50% positive predictive value. CONCLUSIONS: While further validation in an intended-use cohort is needed, the immunocyte transcriptomic model offers a promising tool for risk stratification of individual patients who are being considered for AS.

RESUMEN

INTRODUCTION: We sought to investigate the impact of National Comprehensive Cancer Network (NCCN)-compliant multidisciplinary conference on the uptake of active surveillance (AS) among eligible patients with prostate cancer. METHODS: Retrospective review of our AS database was performed. Patients who are eligible for AS who sought a second opinion at a comprehensive cancer center (2010-2021) were presented to the multidisciplinary Localized Prostate Cancer Conference (LPCC) that includes urologists, radiation oncologists, pathologists, and patient advocates. Cochrane Armitage test was used to examine trends over time. Multivariable regression models were fit to evaluate variables associated with the receipt of AS. RESULTS: Seven hundred twelve patients were identified (19% NCCN very low risk, 32% low risk, and 49% intermediate favorable risk). 43% were recommended AS as the preferred option by the community compared to 68% by LPCC, and 65% elected AS. Recommending AS significantly increased between 2010 and 2021 by the community (from 26% to 57%) and by LPCC (from 52% to 82%), while the proportion of men who received AS increased from 47% to 80% during the same period (P < 0.0001 for all). More recent LPCC era 2017 to 2021 (OR 12.31, 95% CI, 5.60-27.03, P < 0.0001), African American race (OR 0.42, 95% CI, 0.18-0.96, P = 0.04), positive cores at biopsy (OR 0.96, 95% CI, 0.94-0.97, P < 0.0001), age (OR 1.14, 95% CI, 1.10-1.18, P < 0.0001), NCCN low risk (OR 0.25, 95% CI, 0.08-0.81, P = 0.02) and NCCN intermediate favorable risk (OR 0.03, 95% CI, 0.01-0.09, P < 0.0001) were associated with receipt of AS. CONCLUSION: AS recommendation increased significantly over time by community urologists and to a higher extent by NCCN-compliant multidisciplinary conference. The Uptake of AS significantly increased within the same period. More recent LPCC era 2017 to 2021, African American race, the proportion of positive cores at biopsy, age, and NCCN risk were the main determinants of receipt of AS.

RESUMEN

PURPOSE: Currently, there are no accurate markers for predicting potentially lethal prostate cancer (PC) before biopsy. This study aimed to develop urine tests to predict clinically significant PC (sPC) in men at risk. METHODS: Urine samples from 928 men, namely, 660 PC patients and 268 benign subjects, were analyzed by gas chromatography/quadrupole time-of-flight mass spectrophotometry (GC/Q-TOF MS) metabolomic profiling to construct four predictive models. Model I discriminated between PC and benign cases. Models II, III, and GS, respectively, predicted sPC in those classified as having favorable intermediate risk or higher, unfavorable intermediate risk or higher (according to the National Comprehensive Cancer Network risk groupings), and a Gleason sum (GS) of ≥ 7. Multivariable logistic regression was used to evaluate the area under the receiver operating characteristic curves (AUC). RESULTS: In Models I, II, III, and GS, the best AUCs (0.94, 0.85, 0.82, and 0.80, respectively; training cohort, N = 603) involved 26, 24, 26, and 22 metabolites, respectively. The addition of five clinical risk factors (serum prostate-specific antigen, patient age, previous negative biopsy, digital rectal examination, and family history) significantly improved the AUCs of the models (0.95, 0.92, 0.92, and 0.87, respectively). At 90% sensitivity, 48%, 47%, 50%, and 36% of unnecessary biopsies could be avoided. These models were successfully validated against an independent validation cohort (N = 325). Decision curve analysis showed a significant clinical net benefit with each combined model at low threshold probabilities. Models II and III were more robust and clinically relevant than Model GS. CONCLUSION: This urine test, which combines urine metabolic markers and clinical factors, may be used to predict sPC and thereby inform the necessity of biopsy in men with an elevated PC risk.

RESUMEN

OBJECTIVE: To report the outcomes of performing transperineal prostate biopsy in the office setting using the novel anesthetic technique of tumescent local anesthesia. We report anxiety, pain, and embarrassment of patients who underwent this procedure compared to patients who underwent a transrectal prostate biopsy using standard local anesthesia. MATERIALS AND METHODS: Consecutive patients undergoing either a transperineal prostate biopsy under tumescent local anesthesia or a transrectal prostate biopsy with standard local anesthetic technique were prospectively enrolled. The tumescent technique employed dilute lidocaine solution administered using a self-filling syringe. Patients were asked to rate their pain before, during, and after their procedure using a visual analog scale. Patient anxiety and embarrassment was assessed using the Testing Modalities Index Questionnaire. RESULTS: Between April 2021 and June 2022, 430 patients underwent a transperineal prostate biopsy using tumescent local anesthesia and 65 patients underwent a standard transrectal prostate biopsy. Patients who underwent a transperineal biopsy had acceptable but significantly higher pain scores than those who underwent a transrectal prostate biopsy (3.9 vs 1.6, P-value <.01). These scores fell to almost zero immediately following their procedure. Additionally, transperineal biopsy patients were more likely to experience anxiety (71% vs 45%, P < .01) and embarrassment (32% vs 15%, P < .01). CONCLUSION: Transperineal biopsy using local tumescent anesthesia is safe and well-tolerated. Despite the benefits, patients undergoing a transperineal prostate biopsy under tumescent anesthesia still experienced worse procedural pain, anxiety, and embarrassment. Additional studies examining other adjunctive interventions to improve patient experience during transperineal prostate biopsy are needed.

RESUMEN

Background: Isolated pulmonary nodules (SPNs) are small, circular lesions within lung tissue, often challenging to diagnose due to their size and lack of typical imaging features. Timely diagnosis is crucial for treatment decisions. However, the difficulty in qualitative diagnosis necessitates clinical biopsies. Objective: This study aimed to assess the diagnostic accuracy of CT-guided percutaneous lung biopsy for SPNs and identify potential risk factors for malignancy. Methods: We conducted a retrospective analysis of 112 patients with SPNs who underwent CT-guided core needle biopsy (CT-CNB) between June 2020 and June 2022. Histological and cytological results were obtained for all patients, and clinical data and imaging characteristics were compared between benign and malignant SPN groups. Binary logistic regression was used to analyze risk factors for malignancy, and complications were observed. Results: Cytological and histological specimens were successfully obtained for all patients. The cohort consisted of 43 patients with benign SPNs and 69 with malignant SPNs. Among the malignant SPN group, 67 cases were confirmed via CT-CNB and 2 through surgery, resulting in a sensitivity of 97.10% and specificity of 100.00%. The malignant nodules comprised 45 adenocarcinomas, 14 squamous cell carcinomas, 8 metastatic tumors, and 2 small cell carcinomas. Notably, 2 initially diagnosed as malignant cases were found to have chronic inflammation on preoperative biopsy but revealed adenocarcinoma and squamous cell carcinoma post-surgery. The benign nodules encompassed 20 granulomatous inflammation cases, 15 chronic inflammation, 3 fungal granulomas, 2 hamartomas, and 1 fibrous tissue. Cytological smears exhibited a sensitivity of 81.3% and a specificity of 100.0% for malignancy. Significantly, age ≥60, elevated tumor markers, and specific imaging signs (burr, foliation, pleural pull) were identified as risk factors for malignant SPNs using Binary Logistic regression (all P < .05). Conclusions: CT-guided percutaneous lung biopsy demonstrates excellent diagnostic efficacy and safety for distinguishing benign and malignant SPNs.

RESUMEN

BACKGROUND: Surgical access to hypothalamic pathologies can be challenging. Recent case series demonstrate that the transsphenoidal approach to the hypothalamus can be safe and effective, however, may not be feasible in all patients. This study aims to investigate the feasibility of the endonasal transsphenoidal suprasellar subchiasmatic (ETSS) approach to the hypothalamus through a radiological evaluation of the subchiasmatic corridor dimension in an adult population. METHODS: A retrospective review of magnetic resonance imaging of the brain was performed on 164 consecutive adult patients at our institution, of which 100 patients were deemed eligible for inclusion. Measurements were obtained at the two narrowest points along the subchiasmatic corridor: the subchiamastic window, which is the face of the subchiasmatic corridor and the midpoint window, which is located in the middle of the subchiasmatic corridor. Based on defined parameters, including the subchasmiatic window width (SW), subchiasmatic window height (SH), midpoint window width (MW), and midpoint window height (MH), patients were dichotomised into groups: patients with subchiasmatic corridor measurements any dimension of less than 3 mm, or patients with dimensions greater than or equal to 3 mm. RESULTS: A total of 72 (72%) of the study population had dimensions of equal to or greater than 3 mm throughout the entirety of the subchiasmatic corridor, making hypothalamic biopsy feasible through the ETSS route for these patients. CONCLUSION: Based on a radiological evaluation of the subchiasmatic corridor dimension in an Australian adult population, the majority of the population are suitable to undergo an endonasal transsphenoidal suprasellar subchiasmatic biopsy of the hypothalamus.

RESUMEN

INTRODUCTION: With the widespread use of stereotactic radiosurgery (SRS), post-radiation treatment effects (PTREs) are increasing in prevalence. Radiation necrosis (RN) is a serious PTRE which carries a poor prognosis. Since 2012, laser interstitial thermal therapy (LITT) has been used to treat RN. However, reviews have attempting to generalise the efficacy of LITT against biopsy-proven RN are limited. In this systematic review, patient demographic characteristics and post-LITT clinical outcomes are characterised. METHODS: A systematic literature search was conducted in four major databases for cohort studies and case reports published between 2012 and 2022, following the PRISMA 2020 checklist. Data was extracted and descriptively analysed. Quality of reporting was assessed using the PROCESS criteria and reporting bias was evaluated using the ROBINS-I scoring system. RESULTS: Eleven studies met our inclusion criteria, with an overall moderate risk of reporting bias being observed. Mean pre-LITT target lesion volume was 6.75 cm3, and was independent of gender, time since SRS, age and number of interventions prior to LITT. DISCUSSION AND CONCLUSION: LITT is a versatile treatment option which may be used to treat a vast range of patients with refractory biopsy-proven RN. However, neurosurgeons should exercise caution when selecting patients for LITT due to insufficient data on the treatment's efficacy against biopsy-proven RN. This warrants further studies to unequivocally determine the safety and clinical outcomes.

RESUMEN

BACKGROUND: Dermatologists perform a variety of procedures including excisions, biopsies, and other minor surgical procedures. Patients can experience anxiety in anticipation of their surgeries or may develop anxiety during the procedure. Since most dermatologic procedures occur with the patient awake and alert, the physician can offer comforting methods to alleviate some of that anxiety. AIMS: We wanted to provide a review of available methods that dermatologists can use to reduce patient anxiety. MATERIALS & METHODS: In this paper, we review the current literature on methods that can be used in dermatology offices to reduce overall patient anxiety levels. RESULTS: In the preoperative stage, providers can offer educational content to explain the procedure to their patients. Whether it be through telephone calls, educational videos, or utilization of visual models, educating the patient regarding their procedure may reduce their anxiety. Intraoperatively, there are multiple methods that can be used such as music, guided imagery, coloring books, medications, hypnosis, and distraction techniques. DISCUSSION & CONCLUSION: There is a variety of approaches that can be easily implemented in the office and can help in reducing the anxiety of the patients to allow for a pleasant patient experience and an overall satisfactory procedure outcome.

RESUMEN

BACKGROUND: APROPOS was a multicentre, randomized, blinded trial focus on investigating the perineal nerve block versus the periprostatic block in pain control for men undergoing a transperineal prostate biopsy. In the analysis reported here, the authors aimed to evaluate the association of biopsy core count and location with pain outcomes in patients undergoing a transperineal prostate biopsy under local anesthesia. METHODS: APROPOS was performed at six medical centers in China. Patients with suspected prostate cancer were randomized to receive either a perineal nerve block or a periprostatic block (1:1), followed by a transperineal prostate biopsy. The secondary analysis outcomes were the worst pain experienced during the prostate biopsy and postbiopsy pain at 1,6, and 24 h. RESULTS: Between 12 August 2020 and 20 July 2022, a total of 192 patients were randomized in the original trial, and 188 were involved in this analysis, with 94 patients per group. Participants had a median (IQR) age of 68 (63-72) and a median (IQR) prostate volume of 42.51 (30.04-62.84). The patient population had a median (IQR) number of biopsy cores of 15 (12-17.50), and 26.06% of patients had a biopsy cores count of more than 15. After adjusting the baseline characteristics, the number of biopsy cores was associated with the worst pain during the biopsy procedure in both the perineal nerve block group ( ß 0.19, 95% CI: 0.12-0.26, P <0.001) and the periprostatic block group ( ß 0.16, 95% CI: 0.07-0.24, P <0.001). A similar association was also evident for the postbiopsy pain at 1, 6, and 24 h. A lesser degree of pain in both groups at any time (r range -0.57 to -0.01 for both groups) was associated with biopsy cores from the peripheral zone of the middle gland, while other locations were associated with a higher degree of pain. In addition, the location of the biopsy core had less of an effect on pain during the biopsy (r range -0.01-0.25 for both groups) than it did on postbiopsy pain (r range -0.57-0.60 for both groups). CONCLUSIONS: In this secondary analysis of a randomized trial, biopsy core count and location were associated with pain in patients undergoing a transperineal prostate biopsy under local anesthesia. These results may be helpful for making clinical decisions about the anesthetic approach for scheduled transperineal prostate biopsies.
