Efficacy and Safety of Tolvaptan for Patients With Autosomal Dominant Polycystic Kidney Disease in Real-world Practice: A Single Institution Retrospective Study.

Background/aim: We evaluated the efficacy and safety of tolvaptan for autosomal dominant polycystic kidney disease (ADPKD) in real-world practice.

Patients And Methods: We retrospectively reviewed the cases of 27 patients who had been diagnosed with ADPKD between January 2014 and December 2022. Among them, 14 patients received tolvaptan (60 mg/day; morning: 45 mg, night: 15 mg) after being admitted for 2 days.

Laparoscopic redo pyeloplasty with a buccal mucosal graft.

Introduction: Redo pyeloplasty can be difficult due to scar tissue or fibrosis. Ureteral reconstruction with a buccal mucosal graft is performed safely and successfully, but most reports of ureteral reconstruction using a buccal mucosal graft are of robot-assisted surgery, with few reports of laparoscopic-assisted surgery. A case of laparoscopic-assisted redo pyeloplasty using a buccal mucosal graft is presented.

The choice of therapeutic agent in female overactive bladder patients in real-world practice.

Objective: The reasons why anticholinergic drugs or β3 adrenergic agonists are selected as treatments for overactive bladder (OAB) are unclear. The aim of this study was to investigate the background data of female OAB patients that were prescribed anticholinergic drugs or β3 adrenergic agonists in a real-world setting.

Materials And Methods: Between January 2013 and December 2014, 75 patients who had been diagnosed with OAB were included in this study.

Outcomes of dutasteride discontinuation in patients with benign prostatic hypertrophy.

To the Editor, Benign prostatic hyperplasia (BPH) is a common cause of lower urinary tract symptoms (LUTS) in elderly males. The current guidelines recommend the use of a 5-alpha reductase inhibitor (5ARI) to treat males with moderate-to-severe LUTS and an enlarged prostate. Combination therapy with an alpha blocker and a 5ARI has proven effective at ameliorating LUTS and reducing the total prostate volume (TPV) and the risk of the disease progression.

Health-related quality of life and estimation of the minimally important difference in the Functional Assessment of Cancer Therapy-Endocrine Symptom score in postmenopausal ER+/HER2- metastatic breast cancer with low sensitivity to endocrine therapy.

Background: The HORSE-BC study previously demonstrated that second-line endocrine therapy (ET) for patients with acquired endocrine-resistant metastatic breast cancer (MBC) still provided a clinically meaningful benefit. Herein, we investigated the health-related quality of life (HRQOL) in the HORSE-BC study.

Methods: Patients with acquired endocrine-resistant MBC who were scheduled for second-line ET were recruited.

Prospective Cohort Study of Combination Therapy With Abemaciclib and Hormonal Therapy for Chemotherapy-Treated Patients With Hormone Receptor-Positive Metastatic Breast Cancer.

Background: Combination therapy with cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitors and hormonal therapy as the first-line and second-line treatments has already been shown to be effective in patients with hormone receptor-positive (HR+) human epidermal growth factor receptor 2-negative (HER2-) metastatic breast cancer (MBC) in clinical trials. On the other hand, in clinical practice, CDK4/6 inhibitors are used not only as first-/second-line but also as later-line hormonal therapies, or for patients receiving prior chemotherapy in metastatic setting. However, the efficacy and safety of combination therapy in these patients remain unclear.

Successful Response to Nivolumab Plus Ipilimumab Therapy in a Hemodialysis Patient With Metastatic Renal Cell Carcinoma.

Background/aim: There are few reports about the administration of nivolumab plus ipilimumab to hemodialysis patients and their efficacy and safety have not been established yet.

Case Report: A 74-year-old male, who was receiving hemodialysis, was presented with metastatic renal cell carcinoma (mRCC). Two years later, more metastases were found, hence, immunotherapy involving nivolumab plus ipilimumab was initiated.

Impact of Hypertension on Early Renal Dysfunction in Japanese Prostate Cancer Patients Treated With Androgen Deprivation Therapy.

Background/aim: Recently, it was reported that the use of androgen deprivation therapy (ADT) is significantly associated with an increased risk of acute kidney injury (AKI) in patients with newly diagnosed non-metastatic prostate cancer. This study aimed to investigate the incidence of early renal dysfunction in Japanese prostate cancer patients receiving ADT and the factors associated with it.

Patients And Methods: A total of 135 patients who had been pathologically diagnosed with prostate cancer and had received ADT for at least 6 months were eligible for study inclusion.

[Adult Prepubertal-Type Teratoma Diagnosed Using Fish Analysis : A Case Report].

A 34-year-old man visited our hospital complaining of a small painless left scrotal mass. His serum alpha-fetoprotein and human chorionic gonadotropin-beta levels were normal. Ultrasonography revealed a solitary 14 mm mass.

The Association Between Hot Flashes and Renal Dysfunction After Androgen Deprivation Therapy With Radiotherapy in Japanese Patients With High-risk Prostate Cancer.

Background/aim: We investigated the changes in and characteristics of renal function in Japanese patients with high-risk prostate cancer (PCa) who underwent radiotherapy and long-term androgen deprivation therapy (ADT), including those seen after the ADT was discontinued.

Patients And Methods: Among 60 patients who were pathologically diagnosed with PCa and received ADT for 24 months and radiotherapy, 36 patients who underwent treatment for stage B or C PCa were eligible. We assessed renal function using the estimated glomerular filtration rate (eGFR) and investigated the rate of change in the eGFR (ΔeGFR) during and after ADT.

Renal Function Improves After the Discontinuation of Androgen Deprivation Therapy in Japanese Patients With Prostate Cancer.

Background: Androgen deprivation therapy (ADT) is one of the most effective treatments for advanced prostate cancer (PCa). However, it has been reported that the use of ADT is significantly associated with an increased risk of acute kidney injury (AKI) among patients with newly diagnosed non-metastatic PCa. We investigated changes in renal function that occurred in Japanese patients with PCa after ADT was discontinued.

Validation of the Effectiveness of Neutrophil-to-lymphocyte Ratio (NLR) as a Predictive Factor in Patients Undergoing Prostate Biopsy With Prostate Specific Antigen (PSA) Between 4.0 and 10.0 ng/ml.

Background/aim: This study aimed to access the effectiveness of serum neutrophil-to-lymphocyte ratio (NLR) in patients undergoing prostate needle biopsy with a prostate specific antigen (PSA) between 4.0 and 10.0 ng/ml.

High Serum Alkaline Phosphatase Flare after First-Line Androgen Deprivation Therapy Predicts Poor Prognosis in Metastatic Prostate Cancer Patients Treated with Second-Generation Androgen Receptor Targeted Therapy.

Objectives: To determine whether an alkaline phosphatase (ALP) flare after androgen deprivation therapy (ADT) is associated with the treatment response in castration-resistant prostate cancer (CRPC) and predicts the prognosis of metastatic prostate cancer (PCa) patients.

Methods: One hundred and nineteen patients diagnosed with metastatic PCa between 2008 and 2017 were retrospectively studied. The ALP flare ratio was calculated as the ratio of ALP levels 1 month after beginning ADT to ALP levels at diagnosis.

The efficacy of sequential second-line endocrine therapies (ETs) in postmenopausal estrogen receptor-positive and HER2-negative metastatic breast cancer patients with lower sensitivity to initial ETs.

Purpose: Second-line endocrine therapy (ET) for estrogen receptor (ER)-positive and human epidermal growth factor 2 (HER2)-negative metastatic breast cancer (MBC) is offered based on the response to first-line ET. However, no clinical trials have evaluated the efficacy and safety of secondary ETs in patients with poor responses to initial ET. This study evaluated the efficacy of second-line ET in ER-positive and HER2-negative postmenopausal MBC patients with low or very low sensitivity to initial ET.

Trastuzumab, pertuzumab, and eribulin mesylate versus trastuzumab, pertuzumab, and a taxane as a first-line or second-line treatment for HER2-positive, locally advanced or metastatic breast cancer: study protocol for a randomized controlled, non-inferiority, phase III trial in Japan (JBCRG-M06/EMERALD).

Background: Trastuzumab (Tmab), pertuzumab (Pmab), and taxane has been a standard first-line treatment for recurrent or metastatic human epidermal growth factor (HER2)-positive breast cancer (HER2 mBC) but has some safety issues due to taxane-induced toxicities. This has led to ongoing efforts to seek less toxic alternatives to taxanes that are equally effective when used in combination with Tmab plus Pmab. This study aims to show the non-inferiority of eribulin, a non-taxane microtubule inhibitor, against taxane, as a partner for dual HER2 blockade.

Anti-cyclic citrullinated peptide antibody in the cerebrospinal fluid in patients with rheumatoid arthritis who have central nervous system involvement.

Central nervous system (CNS) involvement, including encephalopathy, encephalitis, leptomeningitis, and pachymeningitis, in rheumatoid arthritis (RA) is rather rare. We report the case of a 61-year-old female with a history of RA in remission for 7 years, who presented with numbness, weakness of the left upper limb, dysarthria, and headache. Magnetic resonance imaging (MRI) of the brain showed meningeal enhancement in the frontal, parietal, and temporal lobes.

Invasive pulmonary aspergillosis due to Aspergillus lentulus in an adult patient: A case report and literature review.

Aspergillus fumigatus is the commonest cause of pulmonary aspergillosis; however, a recently developed molecular genetic technique identified A. lentulus as a sibling species. Most of the isolates were found in solid organ recipients, often associated with a fatal outcome.

Tocilizumab-induced psoriasis-like eruption resolved by shortening the dose interval in a patient with rheumatoid arthritis: a case-based review.

Tocilizumab (TCZ) is a humanized antihuman interleukin-6 (IL-6) receptor antibody used for the treatment of inflammatory diseases such as rheumatoid arthritis (RA). While TCZ could act as a therapeutic agent, it has a potential for inducing adverse drug events including psoriasis-like eruption. Seven cases with specific reference to TCZ-induced psoriasis eruption have been reported worldwide so far.
