Successful Endovascular Treatment of a Traumatic Cervical Arteriovenous Fistula After a Carotid Paraganglioma Resection: A Case Report.

Traumatic cervical arteriovenous fistulas are rare, accounting for only 4% of all arteriovenous fistulas. They can be caused by penetrating, or rarely, blunt trauma, resulting in high-pressure arterial blood draining directly into a vein, decreasing distal perfusion. They are seldom reported as a complication of a carotid paraganglioma surgical resection. Historically, arteriovenous fistulas were treated initially conservatively, after that, surgically; nowadays, endovascular treatment, when feasible, is the preferred method as it offers advantages over surgery. This case report describes a rare traumatic cervical arteriovenous fistula that developed after a carotid paraganglioma resection and was successfully treated using coils and Onyx embolic agent via endovascular embolization. After successful embolization, the patient had a smooth recovery and remained stable. In conclusion, vascular injury seems to be the only constant in all acquired cervical arteriovenous fistulas independent of the trauma mechanism; and endovascular treatment, when feasible, is preferred over surgery as it offers superior advantages.

Submandibular Ectopic Parathyroid Adenoma: A Case Report.

Primary hyperparathyroidism (PHPT) is a common endocrine disorder characterized by hypercalcemia and elevated or abnormally normal parathyroid hormone (PTH) levels, due to excessive secretion of PTH by 1 or more parathyroid glands. In this report, we discuss the diagnostic and therapeutic challenges posed by ectopic parathyroid adenomas, a rare but atypical presentation of PHPT. We present the case of a 36-year-old female with PHPT due to an ectopic parathyroid adenoma located in the submandibular region. The patient presented with bone pain and was initially evaluated with routine imaging studies, which were negative. [18F] F-choline positron emission tomography (PET)/Computed tomography revealed the ectopic adenoma, leading to successful surgical management. Ectopic parathyroid adenomas are rare but can occur in various locations, and functional imaging modalities such as choline PET can aid in their detection. Surgical resection remains the definitive treatment for parathyroid adenomas, with intraoperative PTH monitoring guiding the extent of resection. Proper evaluation and management of PHPT is essential to avoid significant morbidity. Our case adds to the growing body of literature on the importance of considering ectopic locations of parathyroid adenomas in patients with PHPT.

Cervical Cutaneous Emphysema after Laser Microsurgery for Treatment of Laryngeal Cancer: Case Report.

Laser laryngectomy is a minimally invasive surgical technique that offers advantages such as precise and limited resections, magnification of the surgical field by microscopy, and improved patient outcomes. However, it is not without risks, and intraoperative complications have been reported, including cervical-cutaneous emphysema. This case report presents a rare complication of cervical-cutaneous emphysema after laser laryngectomy occurring in a 57-year-old patient with glottic carcinoma. The patient underwent laser cordectomy, and after an uneventful procedure, the patient experienced an intense coughing episode followed by swelling and progressive emphysema. The patient was kept under surveillance in the intensive care unit and received ampicillin sulbactam, protective orotracheal intubation, and voice rest. The patient had a good clinical evolution, and the emphysema resolved within 8-10 days. This case highlights the importance of prompt recognition and management of complications that can arise from laser laryngectomy. Although this technique offers several advantages, it is not risk-free, and intraoperative complications can occur. As such, careful consideration and patient selection are important to minimize the risks and achieve successful outcomes.

Prognostic factors for recurrence in patients with papillary thyroid carcinoma.

BACKGROUND: The prognostic factors for tumor recurrence and mortality of patients diagnosed with Papillary Thyroid Carcinoma (PTC) with immediate surgery in Colombia has not been reported. OBJECTIVE: To retrospectively evaluate the risk factors for recurrence and survival at 10 years in patients with the diagnosis of PTC treated at Fundación Santa Fe deBogota (FSFB). METHODS: A total of 486 patients with thyroid surgery accompanied by medical follow-up were recruited. Demographic, clinical, and pathological variables were followed-up for a median period of 10 years. RESULTS: The most significant variables for recurrence were tumors with > 4 cm of size (hazard ratio [HR] = 8.1; 95% confidence interval [CI] = 1.7-55) and extrathyroidal spread (HR = 26.7; 95% CI = 3.1-228). CONCLUSION: PTC in our population has low rates of mortality (0.6%) and recurrence (9.6%), with an average time of recurrence of 3 years. Size of the lesion, positive surgical margins, extrathyroidal spread, and high postoperative serum thyroglobulin (Tg) level act as prognostic factors that determine the likelihood of recurrence. Unlike other studies, the influence of age and gender does not act as a prognostic factor.

Liver Cirrhosis Increases the Risk of Developing Advanced Colon Polyps.

GOALS: To analyze our experience with adenoma detection rates in patients with liver cirrhosis in a community setting. BACKGROUND: Colorectal cancer (CRC) is the third most common cancer and leading cause of cancer death in men and women in the USA. The majority of CRCs arise from premalignant polyps (adenomas), which are typically detected and removed during colonoscopy. Data are limited on the risk of CRC in patients with various chronic liver diseases and the association between CRC and demographics, liver disease etiology and colonoscopy findings. STUDY RESULTS: A total of 351 colonoscopies were performed (2006 to 2019) in patients with liver cirrhosis. Mean age was 62.3 ± 9.4 years, there were 158 females and 193 males. Adenomas were found in 159 procedures (49.07%) and were more likely found in the right colon (76.73%) vs the left colon (18.87%). Left-sided adenoma occurrence was significantly lower in women (61% lower than men, p = 0.05). Neither indication for the procedure (p = 0.08) nor advancing age (p = 0.94) affected adenoma detection rates. No significant differences were observed in the findings of adenomas between different chronic liver diseases. CONCLUSIONS: Adenoma detection rates in patients with cirrhosis (49%) undergoing elective colonoscopy were higher than rates reported in the literature for LT candidates (22-42%) undergoing standardized screenings. Colonoscopy screenings should be expanded to all patients with cirrhosis, regardless of etiology.

Epithelioid hemangioendothelioma of the parotid gland: a case report in an unusual location with a review of the literature / Hemangioendotelioma epitelioide de la glándula parótida: reporte de un caso de una localización inusual y revisión de la literatura

Epithelioid hemangioendothelioma (EHE) is a malignant vascular tumor that usually affects the liver, lung, bone and deep soft tissues of the extremities or trunk. To our knowledge, only 3 cases in the parotid gland have been reported to date. We report a case of a 62-year-old woman who presented with a 1-year history of a slow-growing, painless mass over the left mandibular angle. Imaging studies showed a 2cm mass over the left parotid gland with peripheral calcifications. The patient underwent a superficial parotidectomy. Sections displayed neoplastic epithelioid cells with cytoplasmic vacuoles containing erythrocytes, surrounded by a myxohyaline stroma. Immunohistochemistry was positive for CD31, CD34, ERG, and factor VIII, but negative for cytokeratin AE1/AE3, CK7, EMA, SMA, and S100. The findings were those of an EHE involving the parotid gland. This case demonstrates an EHE in a rare location and emphasizes the need to consider this tumor when diagnosing uncommon soft tissue tumors of salivary glands

El hemangioendotelioma epitelioide (HEE) es un tumor vascular maligno, que generalmente afecta el hígado, los pulmones, los huesos y los tejidos blandos profundos de las extremidades o el tronco. Por lo que sabemos, solo 3 casos reportados en la literatura han descrito este tumor en la glándula parótida. Presentamos el caso de una mujer de 62 años que presentó una historia de un año, de una masa indolora, de crecimiento lento sobre el ángulo mandibular izquierdo. Los estudios de imagen mostraron una masa de 2cm sobre la glándula parótida izquierda con calcificaciones periféricas. La paciente se sometió a una parotidectomía superficial. Los cortes mostraron células epitelioides neoplásicas con vacuolas citoplasmáticas que contenían eritrocitos, rodeadas por un estroma mixohialino. Se demostró mediante técnicas de inmunohistoquímica positividad en la celularidad neoplásica para CD31, CD34, ERG y factor VIII, pero negatividad para la citoqueratina AE1/AE3, CK7, EMA, SMA y S100. Estos hallazgos fueron los de un HEE comprometiendo la glándula parótida. Este caso demuestra un HEE en una localización rara y enfatiza la necesidad de considerar este tumor al diagnosticar tumores raros de tejidos blandos de glándulas salivales

Diagnosis and Management of Functional Chest Pain in the Rome IV Era.

Functional chest pain accounts for about a third of the patients with noncardiac chest pain. It is a very common functional esophageal disorder that remains even today a management challenge to the practicing physician. Based on the definition offered by the Rome IV criteria, diagnosis of functional chest pain requires a negative workup of noncardiac chest pain patients that includes, proton pump inhibitor test or empirical proton pump inhibitor trial, endoscopy with esophageal mucosal biopsies, reflux testing, and esophageal manometry. The mainstay of treatment are neuromodulators that are primarily composed of anti-depressants. Alternative medicine and psychological interventions may be provided alone or in combination with other therapeutic modalities.

Globus: Current Concepts and Dilemmas.

Globus is an area of interest for many medical specialists including otorhinolaryngologists, gastroenterologist, allergists, and psychiatrists. It may be caused by an organic disease, but it is not uncommon that an underlying etiology remains unidentified even after a full workup has been performed. Patients who suffer from globus usually visit several physicians from different specialties without finding a solution for their symptoms. Identifying the underlying cause of globus is not always a simple task; therefore, structural or functional abnormalities of the thyroid, larynx, pharynx, and esophagus should be investigated. Gastroesophageal reflux disease is commonly considered to be the underlying cause after being identified in an otorhinolarygeal (ear, nose, and throat) evaluation, which is usually the first diagnostic step. In the last few years, an inlet patch in the proximal esophagus has been shown to be associated with globus, and its elimination has resulted in symptom resolution in some patients. Finally, globus can be associated with psychiatric disorders as well as oropharyngeal hypersensitivity that could be either chemical or mechanical. Treatment is directed toward an identified organic cause; in those with a functional disorder, the mainstay of therapy includes neuromodulators and psychiatric/psychological interventions.
