Value of Neurostimulation Plus Laryngeal Palpation to Predict Postoperative Vocal Fold Motility.
2021
ABSTRACT Background The aim of this study was to evaluate the reliability of intraoperative neuromonitoring through recurrent laryngeal nerve stimulation and simultaneous laryngeal palpation (NSLP) in predicting postoperative vocal cord palsy and in providing useful information in the decision to perform a staged surgery in initially planned total thyroidectomy. Materials and Methods A retrospective review was performed involving 552 patients for whom a total thyroidectomy was planned. In all patients, preoperative and postoperative laryngoscopy was performed. The incidence of vocal cord palsy was calculated on 1104 nerves at risk. Results Sensitivity and specificity of NSLP were 0.9411 and…
Atypical intraosseous mucoepidermoid carcinoma with two years of evolution and cutaneous infiltration
2018
The intraosseous mucoepidermoid carcinoma is a rare lesion that frequently affects the posterior region of the mandible. This case reports a multilocular osteolytic radiolucency with two years of evolution, that expanded and perforated the cortical bone, with irregular and indefinite margins, that extended from the mandibular angle to the ascendant ramus, with cutaneous ulceration, detected in a 51 years-old male. An incisional biopsy was performed and confirmed the diagnosis of low-grade intraosseous mucoepidermoid carcinoma. The patient was submitted to partial mandibulectomy, neck dissection and post-operative radiotherapy. In three years of follow-up, there was no evidence of tumor recu…
Diagnosis and treatment for central Mucoepidermoid Carcinoma in the mandible: Report of a clinical case in a young patient
2019
A clinical case of a 13 year old male patient with a malignant tumor in the mandibular body area with two years of evolution and associated pain is reported. It was initially diagnosed as low grade central mucoepidermoid carcinoma through Hematoxylin and Eosin (H-E) staining in multiple biopsies. Considering the clinical and radiographic characteristics of the lesion, it was necessary to confirm the diagnosis through Periodic acid-Schiff (PAS). The treatment involved hemimandibulectomy, neck emptying, and complementary radiotherapy. This article aims to present a rare occurrence of this type of intraosseous malignant tumor of glandular origin in a young patient. Key words:Mucoepidermoid car…
CD1a+ and CD207+ cells are reduced in oral submucous fibrosis and oral squamous cell carcinoma
2019
Background The objective of this study investigated the distribution of immature dendritic cells (DCs), Langerhans cells and plasmacytoid DCs in oral submucous fibrosis (OSMF), OSMF associated with oral squamous cell carcinoma (OSMF-OSCC), oral leukoplakia (OL), and oral squamous cell carcinoma (OSCC). Material and Methods Fourteen cases of OSMF, 9 of OSMF-OSCC, 8 of OL¸ 45 of OSCC and 8 of normal epithelium were retrospectively retrieved and their diagnoses confirmed. Immunoreactions against CD1a, CD207 e CD303 were performed and the number of positive cells quantified. Results A significant decrease of CD1a+ was found in OSMF (p≤0.05), OSMF-OSCC (p ≤ 0.01), and OSCC (p ≤ 0.001) when compa…
Transarterielle Chemoembolisation (TACE) des Hepatozellulären Karzinoms (HCC) bei Patienten mit Pfortaderthrombose - Erfahrungen
2007
PURPOSE: Comparative analysis of the course of disease in patients with initial diagnosis of portal vein thrombosis in HCC treated with sequential TACE. Evaluation of the efficacy and safety of the method in a selected patient cohort. PATIENTS AND METHODS: The study included 22 patients with HCC that were palliatively treated at least 3 times with TACE. All patients presented a portal vein thrombosis in the initial CT investigation. The TACE-procedure was carried out in regular intervals using a suspension consisting of a fixed dosage of Mitomycin C (10 mg) and 10-20 ml Lipiodol. Follow-up investigations were carried out with contrast enhanced Multislice-CT before and after TACE and control…
Preoperative imaging of hilar cholangiocarcinoma: surgical evaluation of standard practises.
2004
UNLABELLED It was the goal of this study to compare the results of the preoperative diagnostic workup (ERC, MRC, and PTC) with the tumor extent of the surgical specimen in patients with hilar cholangiocarcinoma (hilCC). PATIENTS AND METHODS Between 9/97 and 12/2002 82 patients with hilCC were treated at our institution. In 59 patients tumor resection was feasible. Preoperative ERC, MRC and PTC - blinded for the idendity of the patients - were analysed retrospectively and compared with the surgical specimen. RESULTS PTC resulted in significantly superior visualization of the bile ducts including the hilar lesion compared to ERC and MRC (p < 0.01). ERC, MRC and PTC were correct in predicting …
The basis, technique and indication for cryosurgery in tumours of the oral cavity and face
1975
The fundamentals of clinical application of crysurgery with very deep freezing of tissues is based on the necrotising effect of extreme cooling. The freezing of extracellular and intracellular free fluid leads to irreversible cell damage, because of a shift of electrolyte concentration to toxic values, and a direct lesion of internal cellular structures. The lesion due to cold occurs as a clear demarcation from the healthy surrounding, almost completely painlessness, and rapid healing without complication. For clinical application in the head and neck, there are cooling instruments fitted with specially shaped, exchangeable probe heads. Convincing results were achieved in the cryosurgical t…
Appleby Procedure (Distal Pancreatectomy With Celiac Artery Resection) for Locally Advanced Pancreatic Carcinoma: Indications, Outcomes, and Imaging
2019
OBJECTIVE. We describe the indications, surgical technique, outcome, and imaging findings in patients with pancreatic ductal adenocarcinoma (PDAC) treated with distal pancreatectomy and celiac artery resection (modified Appleby procedure). CONCLUSION. Distal pancreatectomy and celiac artery resection is a feasible surgery in selected patients with locally advanced PDAC. Knowledge of surgical technique and imaging features may aid radiologists in identifying patients with locally invasive PDAC who might benefit from resection and identifying characteristic distal pancreatectomy and celiac artery resection complications.
Disconnected pancreatic duct syndrome: complete pancreas transection secondary to acute pancreatitis
2016
Disconnected pancreatic duct syndrome is a serious complication of acute pancreatitis which is defined by a complete discontinuity of the pancreatic duct, such that a viable side of the pancreas remains isolated from the gastrointestinal tract. This pancreatic disruption is infrequently observed in the clinical practice and its diagnostic and therapeutic management are controversial. We present an extreme case of disconnected pancreatic duct syndrome with complete duct disruption and pancreatic transection following acute pancreatitis, as well as the diagnostic and therapeutic processes carried out.
Non-functioning parathyroid cystic tumour: malignant or not? Report of a case
2017
Parathyroid carcinoma (PC) is a very rare endocrine tumour, usually characterized by symptoms such as a neck mass, dysphonia, severe hypercalcemia exceeding 140 mg/L and elevated serum parathyroid hormone levels, even more than 5 times the upper limit of normal. Non-functioning parathyroid cancer is extremely rare and, in this case, its pre-operative diagnosis is often difficult. A 54-year old female patient, referring dysphagia and dysphonia, underwent neck ultrasound and neck CT. A left thyroid nodule, probably cystic, was found. It presented caudal extent on anterior mediastinum causing compression of the left lateral wall of the trachea. The preoperative calcemia was into the normal ran…
