A Rare Case of Nodular Mantle Cell Lymphoma of the Gastrointestinal Tract Discovered During a Routine Colonoscopy With a Positive Response to R-CHOP Chemotherapy Regimen.

This report describes the case of a 73-year-old female patient who presented with abdominal symptoms. A colonoscopy identified a cecal mass confirmed as mantle cell lymphoma (MCL). Imaging showed extensive lymph node involvement.

The Effectiveness of Continuous Glucose Monitoring Devices in Managing Uncontrolled Diabetes Mellitus: A Retrospective Study.

This retrospective study aimed to assess the effectiveness of continuous glucose monitoring (CGM) devices in managing uncontrolled diabetes mellitus (DM). The study cohort comprised 25 patients with uncontrolled diabetes who received treatment at an internal medicine resident clinic. The objective was to evaluate the impact of transitioning from self-monitoring of blood glucose (SMBG) to CGM devices on glycemic control, as measured by changes in hemoglobin A1c (HbA1c) levels, average blood glucose levels, hypoglycemic events, time spent within the target blood sugar range, and glucose variability.

Unmasking Type 1 Diabetes in Adults: Insights From Two Cases Revealing Misdiagnosis As Type 2 Diabetes, With Emphasis on Autoimmunity and Continuous Glucose Monitoring.

Type 1 diabetes mellitus (T1DM) is often misdiagnosed as type 2 diabetes mellitus (T2DM) in adults, resulting in inadequate treatment and poor disease management. In this report, we present two patients initially misdiagnosed with T2DM for 14 and four years, respectively, leading to complications like diabetic ketoacidosis (DKA). Reevaluation confirmed adult-onset T1DM through antibody tests.

Benign Intrapulmonary Schwannoma With High Uptake on Fluorodeoxyglucose-18 (FDG-18 PET) Presenting as a Pancoast Tumor.

A 46-year-old female patient was diagnosed with a rare and benign intrapulmonary schwannoma, a neurogenic tumor that represents approximately 20% of adult mediastinal tumors, with schwannomas being the most common subtype. The patient was initially asymptomatic; however, after a period of four years, the patient presented with bilateral extremity edema, chronic venous stasis, elevated right ventricular systolic pressure, and a slightly enlarged inferior vena cava. These symptoms were caused by the lung tumor compressing intrathoracic structures.

Type 2 Decompensated Diabetes Mellitus Weaned off Subcutaneous Insulin Therapy by Utilizing a Continuous Glucose Monitoring Device.

A case series was conducted on three patients diagnosed with decompensated type 2 diabetes mellitus (T2DM) who had hemoglobin A1c (HbA1c) levels ranging from 9.5% to above 14%. Patients were self-monitoring blood glucose (SMBG) levels four times a day.

Sarcoid-Like Reactive Lymphadenopathy in Metastatic Synovial Sarcoma.

A 56-year-old male underwent treatment for sarcoma with metastases to the lungs. Follow-up imaging revealed multiple pulmonary nodules and masses with a favorable response on positron emission tomography (PET) scanning showing enlarging mediastinal lymph nodes concerning for progression of the disease. To evaluate the lymphadenopathy, the patient underwent bronchoscopy with endobronchial ultrasound and transbronchial needle aspiration.

Empagliflozin-Associated Euglycemic Diabetic Ketoacidosis in a Patient With Type 2 Diabetes Mellitus.

Euglycemic diabetic ketoacidosis (euDKA) is an uncommon condition, which is characterized by an elevated anion gap metabolic acidosis with ketonemia/ketonuria, in the presence of normal blood glucose levels. Common risk factors for the development of this condition include pregnancy, prolonged fasting, acute pancreatitis, and bariatric surgery. Sodium-glucose cotransporter-2 (SGLT-2) inhibitors have been identified as a rare cause of euDKA.

Low-Dose Methotrexate Toxicity Presenting as Pancytopenia.

High-dose methotrexate (MTX, 5 g/week) is typically used for the treatment of different malignancies and may be associated with serious side effects, such as acute kidney injury, myelosuppression, and hepatotoxicity. On the other hand, low-dose MTX (10-25 mg/week) is considered to be a safe and effective treatment for autoimmune arthropathies. Toxicity due to low-dose MTX is rare but can present with serious complications, such as pancytopenia.
