Idiopathic infantile hypercalcemia with a variant triggered by vitamin D supplementation in fortified milk: A case report.

Idiopathic infantile hypercalcemia (IIH) is characterized by hypercalcemia, nephrocalcinosis, vomiting, dehydration, and failure to thrive. It is caused by the presence of biallelic loss-of-function variants in the locus. Although hypercalcemia has been linked to the consumption of vitamin D-fortified milk, no reports have documented its role in triggering IIH in patients with variants.

Solitary median maxillary central incisor (SMMCI) syndrome, the mildest form of the holoprosencephaly spectrum, is a rare anomaly characterized by the presence of a single midline central incisor in both the deciduous and permanent dentitions. Affected individuals can present with additional midline defects beyond dental findings. The 22q11.

Deep learning-based histopathological assessment of tubulo-interstitial injury in chronic kidney diseases.

Background: Chronic kidney disease (CKD) causes progressive and irreversible damage to the kidneys. Renal biopsies are essential for diagnosing the etiology and prognosis of CKD, while accurate quantification of tubulo-interstitial injuries from whole slide images (WSIs) of renal biopsy specimens is challenging with visual inspection alone.

Methods: We develop a deep learning-based method named DLRS to quantify interstitial fibrosis and inflammatory cell infiltration as tubulo-interstitial injury scores, from WSIs of renal biopsy specimens.

Severe growth retardation during carbohydrate restriction in type 1 diabetes mellitus: A case report.

Carbohydrate restriction is not typically recommended for children with type 1 diabetes mellitus (T1DM) because of concerns regarding growth retardation, ketoacidosis, severe hypoglycemia, and dyslipidemia. There is no consensus regarding the effects of carbohydrate restriction on the growth of children with T1DM. However, some previously reported cases of T1DM exhibited growth retardation during carbohydrate restriction, whereas others showed no obvious impairment.

Risk stratification of synchronous gastric cancers including alcohol-related genetic polymorphisms.

Background And Aim: We previously identified that ever-smoking and severe gastric atrophy in pepsinogen are risk factors for synchronous gastric cancers (SGCs). This study aimed to determine the association of alcohol drinking status or alcohol-related genetic polymorphism with SGCs and also stratify their risk.

Methods: This multi-center prospective cohort study included patients who underwent endoscopic submucosal dissection for the initial early gastric cancers at 22 institutions in Japan.

Systemic AA Amyloidosis Secondary to Metastatic Renal Cell Carcinoma in a Hemodialysis Patient with Intractable Diarrhea.

We describe an autopsied case of systemic AA amyloidosis secondary to metastatic renal cell carcinoma presenting intractable diarrhea. Severe diarrhea was the major symptom for the diagnosis of AA amyloidosis. No renal symptoms which are common in AA amyloidosis secondary to renal cell carcinoma were shown because hemodialysis following bilateral nephrectomy had already been started 9 years before.

Interleukin (IL)-17A in triple-negative breast cancer: a potent prognostic factor associated with intratumoral neutrophil infiltration.

Background: Triple-negative breast cancer (TNBC) is characterized as highly immunogenic and lacks specific targeted therapies. Interleukin 17A (IL-17A) is a controversial cytokine and is known to have anti-tumor and pro-tumor roles depending on the tumor microenvironment. In addition, IL-17A has been recently implicated in the recruitments of neutrophil into tumor tissues.

Real-world outcomes of patients with renal cell carcinoma, surgically treated at regional hospitals, based on a prospective long-term survey of the pre-robotic era.

Purpose: Renal cancer surgery is frequently performed in small regional hospitals in Japan. This study evaluated the outcomes of renal cancer surgery, comparing results from the pre-robotic surgery era with those obtained with robotic surgery.

Methods: This prospective cohort study was conducted on patients who underwent renal cancer surgery between 2008 and 2013 at 14 hospitals, comprising 13 regional hospitals and a university hospital, registered in the Tohoku Urological Evidence-Based Medicine Study Group.

Efficacy of intraoperative fluorescence imaging using indocyanine green-containing gauze in identifying the appropriate dissection layer in laparoscopic intersphincteric resection: A case report.

In laparoscopic intersphincteric resection, identifying the dissection layer near the anus is often difficult. We safely proceeded with it, using indocyanine green-containing gauze on the anal side to remove the internal anal sphincter with indocyanine green fluorography.

Commercially available novel device to prevent the diffusion of droplets from subjects undergoing esophagogastroduodenoscopy: A pilot study with its prototype.

Introduction: Under the current pandemic situation of the coronavirus disease 2019 (COVID-19), we have newly developed a commercially available device named Endomask to prevent the diffusion of droplets from subjects undergoing esophagogastroduodenoscopy (EGD). Herein, we evaluate the efficacy and safety of the device, and also evaluate the stress of the device on the operators and the subjects of EGD.

Methods: The efficacy of the device was evaluated using an experimental model that simulated the environment of EGD.

Renal recovery following daratumumab, lenalidomide, and dexamethasone therapy in a patient with newly diagnosed dialysis-dependent multiple myeloma.

An 81-year-old Japanese woman was diagnosed with Bence Jones protein κ-type multiple myeloma with acute kidney injury and severe anemia, complicated by congestive heart failure with triple vessel coronary artery disease. Her serum κ-free light-chain (FLC) level was 49,400 mg/L and κ/λ ratio was extremely high at 2373. Her kidney function deteriorated rapidly and required hemodialysis before initiating chemotherapy.

Efficacy of LDL apheresis for the treatment of cholesterol crystal embolism: A prospective, controlled study.

This study was performed to evaluate the efficacy and safety of LDL apheresis (LDL-A) for the treatment of cholesterol crystal embolism (CCE) after cardiovascular procedures. We conducted a prospective multicenter study of 34 patients with CCE and 15 historical control patients. The present participants underwent six sessions of LDL-A for 4 weeks and underwent medical therapy with corticosteroids and statins.

Bortezomib-induced glomerular microangiopathy complicated with monoclonal immunoglobulin deposition disease.

A 75-year-old man admitted with IgG λ-type myeloma with creatinine level of 2.3 mg/dL. Serum lactate dehydrogenase level and platelet count were normal.

Changes in shoulder muscle activities and glenohumeral motion after rotator cuff repair: an assessment using ultrasound real-time tissue elastography.

Background: Although rotator cuff repair is performed to restore the function of the rotator cuff muscles and glenohumeral (GH) joint motion, little has been known regarding the recovery process. The purpose of this study was (1) to investigate changes over time in activities of the supraspinatus and deltoid muscles assessed by ultrasound real-time tissue elastography (RTE) after rotator cuff repair and (2) to determine contributions of the activities of these muscles to the GH joint motion.

Methods: Twenty patients after rotator cuff repair and 13 control participants were enrolled in this study.

Living-Donor Kidney Transplantation With Laparoscopic Nephrectomy From a Donor With Horseshoe Kidney: A Case Report.

Background: In living-donor kidney transplantation, laparoscopic nephrectomy from a donor has become widespread. However, more careful treatment is required for nephrectomy from a donor with horseshoe kidney. This report presents an interesting surgical case of laparoscopic nephrectomy from a donor with horseshoe kidney.

A Case of Multiple Phleboliths on the Medial Side of the Right Mandible.

A 66-year-old female patient was admitted to the orthopedic department due to a left femoral neck fracture. She received perioperative oral management prior to femoral head replacement. Laboratory blood tests indicated an elevated D-dimer level, which suggested the presence of a venous malformation.

Switching to tenofovir disoproxil fumarate in entecavir-treated chronic hepatitis B patients: A pilot randomized controlled study.

Although hepatitis B surface antigen (HBsAg) removal is considered the goal of chronic hepatitis B treatment, it can rarely be achieved with nucleos(t)ide analogues (NAs). It has been reported that tenofovir disoproxil fumarate (TDF) is superior in reducing HBsAg compared with entecavir (ETV) in treatment-naïve patients; however, the effect of TDF in patients who have received NAs is still unclear. The aim of the present study was to evaluate the efficacy of switching from ETV to TDF in patients who were already receiving ETV.
