Sentinel Lymph Node Detection Using SPECT and Gamma Probe in Low-Risk Endometrial Cancer: Efficacy and Factors Associated With Detection Failure.

Introduction: This study examined factors that affected sentinel lymph node (SLN) identification of patients with endometrial cancer having a preoperative estimation of low recurrent risk.

Methods: This study included 97 patients with endometrial cancer who attempted to identify SLN using a uterine cervical injection of technetium-99 m phytate under laparoscopic or robotic-assisted surgery at our institute. A preoperative single photon emission computed tomography (SPECT) and intraoperative gamma probe were used to detect hot nodes.

Follicular Lymphoma Diagnosed Successfully via Endobronchial Ultrasound-Guided Intranodal Forceps Biopsy Located in Left Lymph Node #12.

A 71-year-old man with follicular lymphoma of the right inguinal lymph node was referred to our hospital owing to mediastinal lymph node enlargement (left #12). The patient had a history of cyclosporine (CYS-A) and steroid therapy for fibrotic hypersensitivity pneumonitis. Endobronchial ultrasound-transbronchial aspiration and endobronchial ultrasound-guided intranodal forceps biopsy (EBUS-IFB) were performed under conscious sedation using midazolam and fentanyl.

Real-world experience of tixagevimab/cilgavimab prophylaxis in Japanese patients with immunodeficiency.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes severe illness and mortality in patients with immunodeficiency. Although vaccination has been recommended, the induction of protective antibodies by immunization, and thus the disease-preventive effect, has proven insufficient in immunodeficient patients, especially in those with predominantly antibody deficiency. A monoclonal antibody combination of tixagevimab and cilgavimab (TIX/CIL) was developed as a pre-exposure prophylaxis (PrEP).

Prolonged diagnostic journey in delayed-onset adenosine deaminase deficiency.

Adenosine deaminase (ADA) deficiency typically presents as a severe combined immunodeficiency in early infancy, although its onset may be delayed in some cases. We encountered two patients diagnosed with ADA deficiency in adulthood. In addition to previously reported cases, we aimed to identify and characterize the clinical and immunological features associated with delayed- and late-onset ADA deficiency.

Familial and early recurrent pheochromocytoma in a child with a novel in-frame duplication variant of .

Pheochromocytomas and paragangliomas (PPGLs) are rare neuroendocrine tumors often linked to underlying genetic variants. Genetic analysis can promote gene-adjusted, specific follow-up, and surveillance protocols for both patients and their families at risk. We report the case of a 7-yr-old boy with bilateral pheochromocytoma, which recurred a year after partial adrenalectomy.

Right Ventricular to Pulmonary Artery Uncoupling Is Associated With Impaired Exercise Capacity in Patients With Transthyretin Cardiac Amyloidosis.

Background: Exercise capacity is related to mortality and morbidity in heart failure (HF) patients. Determinants of exercise capacity in transthyretin cardiac amyloidosis (ATTR-CA) have not been established.

Methods And Results: This single-center study retrospectively evaluated ATTR-CA patients and patients with non-amyloidosis HF with preserved/mildly reduced ejection fraction (HFpEF/HFmrEF) (n=32 and n=51, respectively).

Different Impact of Immunosuppressive Therapy on Cardiac Outcomes in Systemic Versus Isolated Cardiac Sarcoidosis.

Isolated cardiac sarcoidosis (iCS) is increasingly recognized; however, its prognosis and the efficacy of immunosuppressive therapy remain undetermined. We aimed to compare the prognosis of iCS and systemic sarcoidosis including cardiac involvement (sCS) under immunosuppressive therapy.We retrospectively reviewed the clinical data of 42 patients with sCS and 30 patients with iCS diagnosed at Kyushu University Hospital from 2004 through 2022.

Atg45 is an autophagy receptor for glycogen, a non-preferred cargo of bulk autophagy in yeast.

The mechanisms governing autophagy of proteins and organelles have been well studied, but how other cytoplasmic components such as RNA and polysaccharides are degraded remains largely unknown. In this study, we examine autophagy of glycogen, a storage form of glucose. We find that cells accumulate glycogen in the cytoplasm during nitrogen starvation and that this carbohydrate is rarely observed within autophagosomes and autophagic bodies.

Allogeneic Hematopoietic cell Transplantation Using Alemtuzumab in Asian Patients with Inborn Errors of Immunity.

Alemtuzumab is used with reduced-toxicity conditioning (RTC) in allogeneic hematopoietic cell transplantation (HCT), demonstrating efficacy and feasibility for patients with inborn errors of immunity (IEI) in Western countries; however, the clinical experience in Asian patients with IEI is limited. We retrospectively analyzed patients with IEI who underwent the first allogeneic HCT with alemtuzumab combined with RTC regimens in Japan. A total of 19 patients were included and followed up for a median of 18 months.

Receptor-mediated cargo hitchhiking on bulk autophagy.

While the molecular mechanism of autophagy is well studied, the cargoes delivered by autophagy remain incompletely characterized. To examine the selectivity of autophagy cargo, we conducted proteomics on isolated yeast autophagic bodies, which are intermediate structures in the autophagy process. We identify a protein, Hab1, that is highly preferentially delivered to vacuoles.

Intracranial residual lesions following early intensification in a patient with T-cell acute lymphoblastic leukemia: a case report.

Background: T-cell acute lymphoblastic leukemia (T-ALL) tends to involve central nervous system (CNS) infiltration at diagnosis. However, cases of residual CNS lesions detected at the end of induction and post early intensification have not been recorded in patients with T-ALL. Also, the ratio and prognosis of patients with residual intracranial lesions have not been defined.

Brain volume measured by synthetic magnetic resonance imaging in adult moyamoya disease correlates with cerebral blood flow and brain function.

Moyamoya disease (MMD) is characterized by progressive arterial occlusion, causing chronic hemodynamic impairment, which can reduce brain volume. A novel quantitative technique, synthetic magnetic resonance imaging (SyMRI), can evaluate brain volume. This study aimed to investigate whether brain volume measured with SyMRI correlated with cerebral blood flow (CBF) and brain function in adult MMD.

Surgical resection of an intraluminal tumor in the azygos vein with an unknown primary site causing superior vena cava syndrome.

Intraluminal tumor in the azygos vein is a rare disease that can cause superior vena cava (SVC) syndrome. Radiotherapy and endovascular stenting with or without chemotherapy are reported to have a high clinical success rate for the management of SVC syndrome with malignancy, but a poor survival rate. Here, we report a 69-year-old man who presented with swelling of the face and upper extremities, who was diagnosed with SVC syndrome caused by an intraluminal tumor in the azygos vein.

Transient erythroblastopenia due to a GATA1 variant in an infant female.

Diamond-Blackfan anemia (DBA) is a congenital anemia with erythroid cell aplasia. Most of the causative genes are ribosomal proteins. GATA1, a hematopoietic master transcription factor required for erythropoiesis, also causes DBA.

Dynamic chest radiography for pulmonary vascular diseases: clinical applications and correlation with other imaging modalities.

Dynamic chest radiography (DCR) is a novel functional radiographic imaging technique that can be used to visualize pulmonary perfusion without using contrast media. Although it has many advantages and clinical utility, most radiologists are unfamiliar with this technique because of its novelty. This review aims to (1) explain the basic principles of lung perfusion assessment using DCR, (2) discuss the advantages of DCR over other imaging modalities, and (3) review multiple specific clinical applications of DCR for pulmonary vascular diseases and compare them with other imaging modalities.

Successful TCRαβ/CD19-Depleted Hematopoietic Cell Transplantation for a Patient With Artemis Deficiency.

Artemis deficiency is characterized by DNA double-strand breaks repairing dysfunction and increased sensitivity to ionizing radiation and alkylating reagents. We describe the first successful case of T-cell receptor [TCR]αβ/CD19-depleted hematopoietic cell transplantation [HCT] for Artemis deficiency in Japan. A 6-month-old Korean boy was diagnosed with Artemis-deficient severe combined immunodeficiency.
