Case Presentation: A 32-year-old man was admitted to the hospital because of dyspnea on exertion for 2 months. Dyspnea occurred in both inspiration and expiration with an associated wheeze that was more pronounced with exertion. He had no other medical history or allergies. The patient was a current one-pack-a-day smoker for the past 5 years. He denied any close personal contact or recent exposure to any patients with active TB. He denied any current symptoms of chest pain, cough, fever, or changes in weight. On a prior admission for similar symptoms, the patient had been diagnosed with asthma and treated with an inhaled corticosteroid/long-acting beta-agonist with no change or improvement in symptoms.

Thyroid nodule is a common disease in clinical practice. The diagnosis of malignant thyroid tumors determines the treatment strategy. Among a number of methods have claimed to help evaluating thyroid nodules, ultrasound is a usable one in spite of several disadvantages (dependent on the physician/technician, incomparable, etc.) and magnetic resonance imaging (MRI) accompanied by quantitative apparent diffusion coefficient (ADC) is a promising diagnostic tool. This study was designed to investigate the usefulness of ADC cut-off values and the protocol of thyroid MRI derived from quantitative diffusion weighted imaging (DWI) in differentiating benign and malignant thyroid nodules. The study was conducted on 93 patients with 128 thyroid nodules, diagnosed and underwent surgery at Hanoi Medical University Hospital. All the patients took thyroid MRI with different b levels (from 200 to 800). ADC value was calculated to each b level, and the statistical tests were conducted with the Statistical Package for Social Sciences (SPSS—Windows and Mac version 20) and STATA 12. The mean ADC with all the b ranging from 200 to 800 of malignant groups was significantly higher than the group of benign lesions (p from <0.001 to 0.01). We chose b = 500 as a standard b-value in the protocol of thyroid MRI. The ADC cut-off point for distinguishing malignant from benign thyroid lesions: 1.7 × 10−3 mm2/s with high accuracy (87.1%, 95% CI: 79.59–92.07%). The study revealed that quantitative diffusion weighted MRI with ADC measurement could potentially quantitatively differentiate between benign and malignant thyroid nodules. [ABSTRACT FROM AUTHOR]

Chyle leak (CL) after head and neck surgery is a rare but well-known complication. In patients with high-output leakage, the treatment can be complicated. This study aims to report on a recent innovation in lymphatic intervention for treating such patients. Materials and Methods: A retrospective review of 36 patients with chyle leak after neck surgery for thyroid cancer was conducted to assess the efficacy of percutaneous lymphatic embolization and thoracic duct (TD) disruption. Results: Antegrade catheterization of the thoracic duct was achieved in 31 of 36 patients (86.1%). Therefore, embolization of the thoracic duct and thoracic duct branches was performed in 26 and 5 patients, respectively. In 5 cases of unsuccessful antegrade catheterization into the thoracic duct, transcervical access embolization was performed in 2 patients, and TD disruption (TDD) was performed in 3 patients. The pooled overall technical success rate of lymphatic embolization was 33/36 patients (91.7%). One patient who underwent thoracic duct embolization (TDE) with technical success (1/33 patients) but clinical failure had additional treatment directly sclerosing the TD under computed tomography scan. Cervical fluid collection sclerotherapy was done in 7 patients as an additional treatment. Resolution of the chyle leak after procedures was observed in all patients (100%). The mean time to resolution was 3 days (1– 7 days). There was no complication intra and after procedures. Conclusion: TDE, selective TD branches embolization and TDD are safe and effective minimally invasive treatments for CL post-surgery for thyroid carcinoma. Sclerosing cervical fluid collection contributes to clinical success. [ABSTRACT FROM AUTHOR]

Case Presentation: A 69-year-old man consulted for a 3-day history of fever, wet cough, and yellow-green phlegm. He denied having any dyspnea, chest pain, hemoptysis, swallowing disorders, choke, chills, asthenia, anorexia, or weight loss. He reported a continuous dry cough and three episodes of pneumonia in the past 4 years. He was a nonsmoker, without any other personal or familial medical history. He had no known professional exposure. He was born and lived in Vietnam but had no known contact with TB in his family or workplace. He was never imprisoned or homeless and did never travel abroad.

Case Presentation: A 24-year-old man was admitted for a new episode of hemoptysis. He reported 3 episodes of hemoptysis in the past 2 years. He had no other medical history and was a nonsmoker. As a Vietnamese person born and living in Vietnam, he was at risk for TB, but had not had contact with those having TB in his family or workplace, was never imprisoned nor homeless, and never traveled abroad. He never experienced pneumonia. He coughed up a small amount of fresh with air red blood (around 5 mL each time) several time for 3 days. He had no dyspnea, no chest pain, no fever, no asthenia, and no anorexia. [ABSTRACT FROM AUTHOR]

Foreign body (FB) ingestion is a common condition encountered in clinical practice, especially among the pediatric age group; however, this occurrence is rare among adults. Some FBs can induce the perforation of the gastrointestinal tract, including fish bones, chicken bones and toothpicks. The ingestion of FBs is rarely associated with bowel perforation, and most FBs are passed spontaneously. The ingestion of sharp and pointed objects typically produces adverse events related to the upper gastrointestinal system, and FBs are rarely retained in the colon. Bowel perforation caused by the ingestion of FBs should be diagnosed and treated in a timely manner. Here, we present the unusual case of a 51-year-old male who presented to the emergency room with complaints of acute abdominal pain secondary to fish bone ingestion, which triggered cecum perforation.
