Autologous intraarterial pancreatic bone-marrow mononuclear cells infusion in T2D patients: Changes on beta-cells function, insulin resistance, and inflammatory marker.

BACKGROUND: Type 2 diabetes (T2D) is a progressive disease. Many drugs currently being used for the management of T2D have minimal effect on pancreatic beta cells regeneration. Cell-based therapies might provide potential benefits in this aspect. METHODS: A pilot study in five T2D patients with 12 months follow-up was performed to evaluate the effect of autologous bone marrow mononuclear stem cells (BM-MNCs) infusion into pancreatic arteries on the insulin requirement, beta-cell function, insulin resistance, and systemic inflammatory marker (CRP). RESULTS: The primary endpoint, a 50 % reduction of total insulin doses from baseline, was not achieved in this study. However, a trend of increasing fasting C-peptide (p = 0.07) and C-peptide 60' (p = 0.07) and 90' (p = 0.07) after a mixed-meal tolerance test was observed 12 months post-infusion compared to baseline levels. A similar result was observed for the homeostatic model assessment of beta cell function (HOMA1-B), an index for beta cell function. No improvement was observed for insulin resistance measured by homeostasis model assessment of insulin resistance (HOMA1-IR) and systemic inflammatory parameter. CONCLUSION: Intraarterial pancreatic autologous BM-MNCs infusion might potentially improve beta cell function in T2D patients, although further study is needed to confirm this finding.

Multiple myocardial bridging in the elderly: A rare case.

Myocardial bridging occurs when a segment of major epicardial coronary artery courses intramurally through myocardium, commonly involving the left anterior descending. However, myocardial bridging involving coronary arteries other than left anterior descending is less-common and rarely reported, especially in the elderly population. We report a rare case of multiple myocardial bridging involving the left anterior descending, first obtuse marginal, and ramus intermedius in a 68-year-old Asian female. We also briefly discuss the imaging evaluation and pathophysiology of myocardial ischemia in myocardial bridging. This is the second reported case of myocardial bridging involving such combination, and to our knowledge, the first for elderly patient.

Comprehensive evaluation on cancer of unknown primary site and how we managed it: A case report.

INTRODUCTION AND IMPORTANCE: Cancer of unknown primary site (CUP) is metastatic cancer without primary tumor found from comprehensive medical history, physical examination, and regular laboratory examination. Eighty percent of CUP include unfavorable groups with 3 to 6 months of median survival despite chemotherapy treatment. CASE PRESENTATION: A 52-year-old male was presented with a chief complaint of a recurrent lump in the neck and axilla. After comprehensive examinations over three years, the primary site of the metastatic tumor could not be found. Therefore, this patient was diagnosed with cancer of an unknown primary site. CLINICAL DISCUSSION: In patient with CUP, more precise therapy can only begin when the exact form of cancer is identified. However, the delay in diagnosis would worsen the patient's condition, as treatment measures cannot be implemented. CONCLUSION: Trimodal modalities including surgery, chemotherapy, and radiotherapy are suitable for CUP with squamous cell carcinoma proven in immunohistochemistry evaluation.

Giant Recurrence Pituitary Adenoma After Three Times Transphenoidal Removal Surgery, One Craniotomy Procedure, and 30 Doses of External Radiotherapy.

This is a case of 42nd year-old woman with history of sight loss in her both eyes. She experienced headache and visual field decrease gradually since 2014. After several laboratory and imaging examinations, from her dynamic pituitary magnetic resonance imaging (MRI), it is concluded that she had a giant adenoma of the pituitary gland which compressed to her optic chiasm. From her pituitary laboratory hormone panel, it is revealed that the tumor is a non-functioning pituitary adenoma. From the neuro-ophthalmology (campimetry) examinations, she had papillae atrophy in her both eyes and also bilateral temporal hemianopia.

Autologous Bone-Marrow vs. Peripheral Blood Mononuclear Cells Therapy for Peripheral Artery Disease in Diabetic Patients.

Diabetes mellitus (DM) remains one of the most important risk factors for peripheral artery disease (PAD), with approximately 20% of DM patients older than 40 years old are affected with PAD. The current standard management for severe PAD is endovascular intervention with or without surgical bypass. Unfortunately, up to 40% of patients are unable to undergo these revascularization therapies due to excessive surgical risk or adverse vascular side effects. Stem cell therapy has emerged as a novel therapeutic strategy for these 'no-option' patients. Several types of stem cells are utilized for PAD therapy, including bone marrow mononuclear cells (BMMNC) and peripheral blood mononuclear cells (PBMNC). Many studies have reported the safety of BMMNC and PBMNC, as well as its efficacy in reducing ischemic pain, ulcer size, pain-free walking distance, ankle-brachial index (ABI), and transcutaneous oxygen pressure (TcPO2). However, the capacity to establish the efficacy of reducing major amputation rates, amputation free survival, and all-cause mortality is limited, as shown by several randomized placebo-controlled trials. The present literature review will focus on comparing safety and efficacy between BMMNC and PBMNC as cell-based management in diabetic patients with PAD who are not suitable for revascularization therapy.

Effect of melatonin supplementation in combination with neoadjuvant chemotherapy to miR-210 and CD44 expression and clinical response improvement in locally advanced oral squamous cell carcinoma: a randomized controlled trial.

BACKGROUND: Squamous cell carcinoma of the oral cavity (OSCC) is the sixth most common malignancy. Surgery is mainstay treatment for oral cancers. Surgery in locally advanced OSCC presents many challenges primarily because the head and neck have critical structures that can be damaged by tumor or treatment. It is thought that neoadjuvant chemotherapy (NC) in locally advanced OSCC is able to shrink tumor size. Chemoresistancy is a problem due to hypoxic microenvironment characterized by increased expression of HIF-1α. It is also regulated by miR-210 as well as increased expression of CD44 and CD133. Melatonin has a powerful antioxidant and oncostatic effects that are expected to improve tumor hypoxia and clinical response. Fifty patients with OSCC were included and randomized. miR-210 and CD44 expression were measured before and after intervention using qRT-PCR absolute quantification, and clinical response was evaluated according to RECIST 1.1 criteria. This study aims to determine the effect of melatonin in improving the clinical response of patients with locally advanced oral squamous cell carcinoma (OSCC) after neoadjuvant chemotherapy to miR-210 and CD44 expression. RESULTS: Melatonin administration reduced miR-210 levels but not significant (p = 0.767). CD44 expression also decreased in the melatonin group compared with placebo yet was not significant (p = 0.103). There was a decrease in the expression of miR-210 and CD44 followed by a decrease in the percentage of residual tumor but not significant (p = 0.114). CONCLUSION: In OSCC, the addition of 20-mg melatonin to neoadjuvant chemotherapy (NC) reduced the expression of miR-210 and CD44 and decreased the percentage of tumor residue; however, no statistically significant result was observed. TRIAL REGISTRATION: This study is registered to ClinicalTrials.gov under trial registration number: NCT04137627 with date of registration on October 22, 2019-retrospectively registered, accessible from: https://clinicaltrials.gov/ct2/show/NCT04137627.

The role of diagnostic and interventional radiology in juvenile nasopharyngeal angiofibroma: A case report and literature review.

Juvenile Nasopharyngeal Angiofibroma is a rare and locally aggressive benign tumor. It is characterized by high vascularization leading to spontaneous bleeding or massive hemorrhage. We reported a case of 13 years old boy with a swollen at the right face, nasal congestion, recurrent nose bleeding, hyposmia, headache, breathing difficulty, and a nasopharyngeal mass at CT scan. Angiography examination showed a highly vascularized mass which was successfully occluded through preoperative embolization procedures. It is suggested that imaging modalities is not only playing an important role in diagnostic process, but also as an adjunct treatment approach in patient with Juvenile Nasopharyngeal Angiofibroma.
