Treatment of a left inguinal hernia with incarceration of the scope during colonoscopy: a case report and literature review.

Background: Colonoscopy is widely performed. However, reports of colonoscopic incarceration within inguinal hernias are rare. Incarceration during colonoscopy is a critical condition, and attempting forced reduction may exacerbate complications; therefore, a careful approach is required.

Laparoscopic extraperitoneal approach for lateral lymph node dissection for patients with metachronous lateral pelvic lymph node metastases following surgery for rectal cancer: a case series and short-term outcomes.

Background: There have been few reports of a totally extraperitoneal approach for laparoscopic lateral lymph node dissection (LLND) for patients with metachronous lateral pelvic lymph node metastases following surgery for rectal cancer. Therefore, this study reports the short-term outcomes of LLND via an extraperitoneal approach.

Methods: A total of 10 patients underwent LLND through a laparoscopic extraperitoneal approach in our hospital since October 2018.

[A Case of Recurrent Breast Cancer with Delayed Wound Healing Induced by Bevacizumab].

Bevacizumab plus paclitaxel therapy for recurrent breast cancer did not prolong overall survival(OS)in clinical trials, but it was efficacious for treating life-threatening HER2-negative recurrent breast cancer. This regimen is often used in daily clinical practice by breast surgeons. However, bevacizumab therapy results in unique adverse events, of which proteinuria and hypertension are relatively frequent.

A Case of Type 2 Diabetes Mellitus with Lung Cancer Suffered from Euglycemic Diabetic Ketosis Accompanied by Adrenal Insufficiency after Immune Checkpoint Inhibitors.

A 74-year-old patient with type 2 diabetes mellitus received basal-bolus insulin, insulin secretagogues, and sodium glucose transporter 2 (SGLT2) inhibitors. After immune checkpoint inhibitor treatment for lung cancer, he suffered from depressed consciousness with a urinary ketone body (3+). When all hypoglycemic treatments were discontinued, his serum blood glucose remained at 121 mg/dL.

[A Case of Severe Drug-Induced Lung Injury during Preoperative Chemotherapy for Breast Cancer in the Early Stages of the COVID-19 Epidemic].

Drug-induced interstitial lung disease(DILD)is defined as a drug-related respiratory disorder that occurs during drug administration. For diagnosis, it is important to differentiate similar diseases. We report a case of severe drug-induced lung injury during preoperative chemotherapy for breast cancer in the early stages of the COVID-19 epidemic, which was difficult to diagnose.

Infectious virus shedding duration reflects secretory IgA antibody response latency after SARS-CoV-2 infection.

Infectious virus shedding from individuals infected with severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) is used to estimate human-to-human transmission risk. Control of SARS-CoV-2 transmission requires identifying the immune correlates that protect infectious virus shedding. Mucosal immunity prevents infection by SARS-CoV-2, which replicates in the respiratory epithelium and spreads rapidly to other hosts.

[A Case of COVID-19 Infection during Postoperative Chemotherapy for Breast Cancer Treated with Antibody Cocktail Therapy to Prevent Disease Aggravation].

The outbreak of COVID-19 has caused a global pandemic, and it has been reported that patients with cancer are at high risk of developing complications from the disease. However, we believe that prolonged interruption of chemotherapy due to extended COVID-19 treatment is not desirable, given the intensity of cancer treatment. We report a case of COVID-19 infection during postoperative chemotherapy for breast cancer, in which antibody cocktail therapy prevented disease aggravation and delayed breast cancer treatment.

[ESR1 Mutation-Positive Recurrent Breast Cancer Successfully Treated with Letrozole plus Abemaciclib].

Approximately 70% of breast cancers are estrogen receptor(ER)positive, an indication for endocrine therapy. The first choice of treatment for ER-positive metastatic recurrent breast cancer is endocrine therapy, which has relatively few side effects; however, many of these side effects become resistant during treatment. One of the resistance mechanisms is mutations in the ESR1 gene, which have also been found to occur after long-term aromatase inhibitor(AI)treatment.

[A Case Study of Successful Breast Cancer Treatment after Recovery from Drug-Induced Interstitial Lung Disease].

Drug-induced interstitial lung disease(DILD)is a possible complication of many anticancer drugs. When DILD occurs during breast cancer treatment, choosing the right drug for subsequent treatment is often difficult. In our first case, the patient developed DILD during dose-dense AC(ddAC)therapy; however, the disease resolved with steroid pulse therapy, and the patient underwent surgery without disease progression.

[Olaparib Could Be Re-Administered after Chemotherapy].

Olaparib, a PARP inhibitor, was approved in 2018 for BRCA1/2 gene mutation and HER2-negative inoperable or recurrent breast cancer with previous chemotherapy. Olaparib is an important drug with minor adverse events compared to chemotherapeutic drugs. In addition, it is expected to exert a high therapeutic effect on breast cancer with BRCA mutations due to its characteristics.

An individual's physique is associated with the length of the reconstruction route via the retrosternal approach.

We hypothesized that an individual's physique is related to reconstruction length, as organs reconstructed via the retrosternal route are curved toward the ventral side. This study aimed to determine factors contributing to the reconstruction length of the retrosternal route. Fifty patients underwent subtotal esophagectomy with esophagogastric reconstruction via the posterior mediastinal route between 2010 and 2014; the esophagus-stomach and posterior mediastinal route lengths were measured to evaluate whether they could be approximated.

Glove-shaped Foam with Negative Pressure Wound Therapy for Skin Graft Fixation on the Hand.

Tie-over bolster dressing has been the gold standard for skin graft immobilization. However, skin grafting onto the hand remains challenging. To prevent shearing of the skin, joint fixation with Kirschner wire and casting is often required.

Postoperative results of the in situ fenestrated open stent technique for acute aortic dissection type A.

Objective: Total arch replacement is commonly used for acute aortic dissection type A at some facilities, especially since open stent grafting became commercially available in Japan. Left subclavian artery (LSCA) reconstruction involves deep view manipulation, is difficult to expose and anastomose, and involves the risk of complications and surrounding vascular injury.

Methods: We evaluated 137 patients (mean age 73.

A comparative analysis of children born with low birthweight and attention deficit hyperactivity disorder.

Background: We aimed to compare the profile of the Wechsler Intelligence Scale for Children Fourth Edition (WISC-IV) between Japanese schoolchildren born very preterm (VP) and with very low birthweight (VLBW) and those with attention deficit hyperactivity disorder (ADHD), and to identify the specific neurocognitive characteristics of VLBW/VP children.

Methods: The VLBW/VP group in the present study included 50 (19 male, 31 female) first- to third-grade elementary school children born between January 2008 and February 2013 at Osaka Medical and Pharmaceutical University Hospital and Saiseikai Suita Hospital with birthweights <1,500 g and <32 gestational weeks. The ADHD group included 18 (13 male, 5 female) first- to third-grade elementary school children who visited Osaka Medical and Pharmaceutical University Hospital between January 2019 and October 2021.

Unplanned hemodialysis initiation and low geriatric nutritional risk index scores are associated with end-stage renal disease outcomes.

Patients with end-stage renal disease (ESRD) have a low nutritional status and a high mortality risk. The geriatric nutritional risk index (GNRI) is a predictive marker of malnutrition. However, the association between unplanned hemodialysis (HD) and GNRI with mortality remains unclear.

Usefulness of ultrasonography for small intestinal evaluations in pediatric Crohn's disease.

Background: Small bowel capsule endoscopy (SBCE) for Crohn's disease is useful; however, its use has some limitations, such as invasiveness when endoscopic assistance is required in patients who cannot swallow the capsule, and the burden of interpretation on a physician. In contrast, intestinal ultrasonography (IUS) is a non-invasive modality for children. The purpose of this study is to evaluate the accuracy of IUS for pediatric patients with established Crohn's disease.

Successful Laparoscopic Treatment of Pancreatic Metastasis From Sigmoid Colon Cancer: A Case Report.

Progressive colorectal cancer frequently presents with various manifestations, including hepatic, pulmonary, and peritoneal metastases, as well as local and anastomotic site recurrences. However, pancreatic metastasis is extremely rare. Complete surgical resection is currently considered the most effective and only potentially curative treatment for colorectal cancer with distant metastases.

Three cases of macular hole that occurred in inferior scleral staphyloma associated with tilted disc syndrome: a case series.

Background: The objective is to examine the clinical characteristics of three patients with macular hole that occurred in inferior posterior staphyloma associated with tilted disc syndrome.

Case Presentations: This study involved three eyes of three Japanese female patients (mean age 76.0 years, range 73-84 years) with macular hole occurring in inferior posterior staphyloma associated with tilted disc syndrome.

Prevalence and Risk Factors of Silent Cerebral Microbleeds in Patients with Coronary Artery Disease.

Objectives: Cerebral microbleeds (CMBs), which can be detected by gradient-echo T2*-weighted magnetic resonance imaging (MRI), represent small chronic brain hemorrhages caused by structural abnormalities in cerebral small vessels. CMBs are known to be a potential predictor of future stroke, and are associated with age, various cardiovascular risk factors, cognitive impairment, and the use of antithrombotic drugs. Patients with coronary artery disease (CAD) are at potentially high risk of CMBs due to the presence of coexistent conditions.

Comparison Between Second- and Third-generation Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitors as First-line Treatment in Patients With Non-small-cell Lung Cancer: A Retrospective Analysis.

Background: For epidermal growth factor receptor (EGFR)-mutated non-small cell lung cancer (NSCLC), administration of EGFR tyrosine kinase inhibitors (TKIs) is mandatory to prolong survival. To date, a comparison of second- and third-generation EGFR-TKIs has not been reported as far as we are aware.

Patients And Methods: We retrospectively investigated the survival time of patients diagnosed with EGFR-mutated advanced or recurrent NSCLC who had received afatinib, a second-generation EGFR-TKI, or osimertinib, a third-generation EGFR-TKI, as the first-line treatment.
