Article Synopsis
  • * A study of 215 schwannomas revealed that 13.5% had the fusion, with the highest prevalence in peripheral somatic tissues, and a unique 'serpentine' palisading pattern was noted in most fusion-positive cases.
  • * The presence of this serpentine pattern correlated with the fusion status, suggesting it could be used as a predictive marker, along with tumor size, patient age, and location, while advanced RNA techniques confirmed the fusion's existence.

: Women with interstitial cystitis (IC) suffer from spontaneous serious bladder pain symptoms without immediate resolution. Women with IC may lack knowledge of how to help themselves. Therefore, a measurement of IC self-help and medical-resource-seeking for women with IC is needed.

Article Synopsis
  • DRESS is a serious drug-induced allergic reaction characterized mainly by skin symptoms and can also cause lymphadenopathy, which is rarely documented in pathology.
  • A case series of five patients highlighted different lymph node biopsy patterns, including AITL-like and Kikuchi-like features, making diagnosis challenging.
  • Correct identification of DRESS-related lymphadenopathy is crucial to differentiate from conditions like AITL, as misdiagnosis can lead to inappropriate treatments.

Technological advances in thyroid surgery have rapidly increased in recent decades. Specifically, recently developed energy-based devices (EBDs) enable simultaneous dissection and sealing tissue. EBDs have many advantages in thyroid surgery, such as reduced blood loss, lower rate of post-operative hypocalcemia, and shorter operation time.

Article Synopsis
  • A study was conducted to evaluate the risk of severe acute exacerbation of Hepatitis C virus (HCV) infection in cancer patients receiving chemotherapy, as no guidelines previously existed for this situation.
  • The results showed that HCV-infected cancer patients experienced a significantly higher rate of severe liver injury compared to non-infected patients, particularly among those with hematological cancers.
  • Key risk factors for exacerbation included the use of rituximab-containing chemotherapy and having a hematological malignancy, emphasizing the need for pre-chemotherapy HCV testing in these patients.

Background: This study aims to investigate the self-perception of symptoms, medical help seeking, and self-help strategies of women with interstitial cystitis (IC).

Methods: A mixed method of qualitative and quantitative approaches was employed. The qualitative approach used in-depth interviews about the subjective experience of symptoms, medical help seeking, and self-help strategies for their IC.

To evaluate clinical outcomes and to identify prognostic factors in isolated para-aortic lymph node (PALN) recurrence, we retrospectively reviewed 65 patients who developed PALN recurrence as the first site of tumor progression from a total of 1521 patients who were treated with curative pelvic radiation therapy (RT) for uterine cervical carcinoma between May 1993 and January 2017. Forty-five of the 65 patients received salvage therapy. The median salvage PALN radiation dose was 54 Gy (range: 18 to 62 Gy).

Intraoperative injury to the recurrent laryngeal nerve (RLN) can cause vocal cord paralysis, which interferes with speech and can potentially interfere with breathing. In recent years, intraoperative neural monitoring (IONM) has been widely adapted as an adjunct technique to localize the RLN, detect RLN injury, and predict vocal cord function during the operations. Many studies have also used animal models to investigate new applications of IONM technology and to develop reliable strategies for preventing intraoperative RLN injury.

Background: Intraoperative neural monitoring (IONM) has gained widespread acceptance as an adjunct to the gold standard of visual identification of the recurrent laryngeal nerve (RLN) during thyroid surgery. Currently, laryngeal electromyography (EMG) recording during IONM is almost always performed using endotracheal tube (ETT) surface electrodes placed adjacent to vocal folds originating from the inner surface of the thyroid cartilage (TC). Therefore, it was hypothesized that surface recording electrodes placed on the outer surface of the TC should enable access to the EMG response of the vocal folds during IONM.

Background: This study aimed to investigate the effectiveness of monotherapy acetylsalicylic acid (ASA) and warfarin for stroke prevention in low-risk atrial fibrillation (AF) by using a population- -based cohort study in Taiwan.

Methods: A newly diagnosed low-risk AF patient cohort were identified by using National Health Insurance Research Database (NHIRD) in Taiwan in 2008. The study cohort was observed with a follow-up of 2 years to examine the onset of ischemic stroke (IS) (to 2010).

Background: To scrutinize the pretreatment prognosticators on survival and late toxicities in a homogenous cohort of nasopharyngeal carcinoma (NPC) patients treated by simultaneous integrated boost intensity-modulated radiation therapy (SIB-IMRT).

Methods: A total of 219 non-distant metastatic NPC patients consecutively treated by SIB-IMRT at a single institute were collected. The pretreatment factors including the socio-demographic variables, TNM stages, gross tumor volume (GTV), Epstein-Barr virus (EBV)-DNA, and hematologic inflammatory markers were analyzed.

Background: Patients treated with radiotherapy are at risk of developing a second cancer during their lifetime, which can directly impact treatment decision-making and patient management. The aim of this study was to qualify and compare the secondary cancer risk (SCR) after intensity-modulated radiation therapy (IMRT) and volumetric-modulated arc therapy (VMAT) in nasopharyngeal carcinoma (NPC) patients.

Patients And Methods: We analyzed the treatment plans of a cohort of 10 NPC patients originally treated with IMRT or VMAT.

oxLDL is involved in the pathogenesis of atherosclerotic lesions through cholesterol accumulation in macrophage foam cells. Andrographolide, the bioactive component of Andrographis paniculata, possesses several biological activities such as anti-inflammatory, anti-oxidant, and anticancer functions. Scavenger receptors (SRs), including class A SR (SR-A) and CD36, are responsible for the internalization of oxLDL.

Propensity score matching evaluates the treatment incidence of radiation-induced pneumonitis (RP) and secondary cancer risk (SCR) after intensity-modulated radiotherapy (IMRT) and volumetric-modulated arc therapy (VMAT) for breast cancer patients. Of 32 patients treated with IMRT and 58 who received VMAT were propensity matched in a 1:1 ratio. RP and SCR were evaluated as the endpoints of acute and chronic toxicity, respectively.

Purpose: Cranial nerve (CN) palsy is the main symptom in patients with locally advanced nasopharyngeal carcinoma (NPC). This study aimed to evaluate the therapeutic outcome of NPC with CN palsy and to analyze the prognostic factors.

Patients And Methods: A total of 104 NPC patients with CN palsy curatively treated by conventional (n=44) or conformal (n=60) radiotherapy (RT) were enrolled.

Purpose: To evaluate the differences in the treatment outcomes and complications between elderly patients and younger patients with uterine cervical cancer (CxCa).

Methods And Materials: From April 1993 to December 2007, 138 CxCa patients aged ≥75years (Elderly group) and 334 CxCa patients aged <60years (Young group) who underwent definitive radiotherapy/chemoradiotherapy at our institution were reviewed. Two propensity score-matched cohorts of patients were selected from both age groups to evaluate the differences in the outcomes and complications.

Background And Objectives: The aim of this study was to evaluate the cost effectiveness of novel oral anticoagulants (NOACs) for stroke prevention among atrial fibrillation (AF) patients by incorporating Taiwanese demographic information derived from a population-based database, the National Health Insurance Research Database (NHIRD), into cost-effectiveness analysis.

Methods: From 1 January to 31 December 2012, 98,213 AF patients were selected from the NHIRD database. A Markov model was constructed that combined published secondary data with the Taiwan NHIRD to compare the cost and incremental cost effectiveness of apixaban 5 mg twice daily, dabigatran 110 or 150 mg twice daily, rivaroxaban 20 mg once daily, and warfarin.
