Sonographic evaluation of anterior cervical lymph nodes.

PURPOSE: In this study we evaluated the role of ultrasound in diagnosis of anterior cervical lymph (ACL) node disease. METHODS: Three-hundred and sixty-six patients were included in the study. When ACL nodes were found, we noted the station(s) involved, the number, and the short and long axis of each. Patients had their thyroid investigated and were then divided into four groups: no sonographic signs of thyroid abnormality, already diagnosed autoimmune thyroiditis, probable new diagnosis of autoimmune thyroiditis, and thyroid nodules. RESULTS: ACL nodes were found in 127 out of 366 patients examined. The 127 patients with ACL nodes were classified into group 1 (2 patients), group 2 (97 patients), group 3 (23 patients), and group 4 (5 patients). The only differences were the presence and number of lymph nodes in the prelaryngeal and/or prethyroidal and/or pretracheal stations, and the number of "acutely inflamed" nodes in group 3 compared with all the other groups. CONCLUSION: We observed a strong association between anterior cervical lymphadenopathy and autoimmune thyroiditis; this is certainly a good reason to justify thorough evaluation of anterior cervical lymph nodes for all patients with suspected thyroiditis.

Ultrasound evaluation of the first finger's sesamoid bones: diagnostic value of sesamoid and subsesamoid indices.

PURPOSE: Our analysis focuses explicitly on applying two sonographic and morphological indexes (sesamoid index and subsesamoid index) to better evaluate post-traumatic consequences to the sesamoids of the first finger. METHODS: In 2 years, we enrolled 75 patients, divided into two groups: 60 without any history of trauma and 15 reporting hyperextension trauma of the first finger. We performed clinical and instrumental examinations (sonography and X-ray) on patients with one or more symptoms compatible with sesamoiditis, while an MRI scan was performed only on patients with an acute onset and severe symptomatology. We measured both the short and long-axis diameter (in mm) for each sesamoid as well as the relation between the two parameters (sesamoid index, SI and subsesamoid index, SubI). RESULTS: All 15 patients showed sonographic alterations of the SI above the reference range, while the alterations of SubI varied according to the acuteness and gravity of trauma. In all cases, the X-ray did not show any relevant alterations. MRI scans in patients with acute symptoms confirmed the sonographic findings. CONCLUSION: Sonography enabled diagnosis of micro-injuries which were invisible to X-Ray and allowed to detect possible damages to the sesamoid complex, providing a qualitative and quantitative evaluations of the post-traumatic alteration of the metacarpophalangeal joint of the 1st finger and is therefore valid, combined with clinical examination and hand X-ray, in the evaluation of sesamoiditis without the need to perform further examinations.

Masseter-facial neurorrhaphy for facial palsy reanimation: What happens after masseter denervation? Histomorphometric and stomatognathic functional analysis.

The aim of the present study was to analyse the consequences of masseter muscle denervation. In facial palsy surgical treatment, the masseteric nerve constitutes an important nerve source for facial reanimation due to its anatomical position and large amount of available axons. Computed tomography and/or magnetic resonance imaging were performed in 30 control subjects, and three radiologists separately measured the longitudinal diameter (LD), anteroposterior diameter (APD), transverse diameter (TD), and skeletal muscle area (SMA) of the masseter muscles as reference values. Regarding the facial palsy group, from 2009 to 2018, 11 patients (4 men and 7 women) were selected on the following inclusion criteria: diagnosis of unilateral facial paralysis, minimum follow-up of 14 months, absence of temporomandibular dysfunction, presence of complete dentition (to minimise bias of stomatognathic evaluation), complete clinical and radiological records. The mean LD, APD, TD, and SMA values of the healthy and denervated masseter muscles were obtained and compared. Stomatognathic function was clinically examined through mean mouth opening (MMO) and Maximum Bite Force (MBF). Furthermore, facial symmetry analysis (FSA) was carried out using EMOTRICS Software. Reference values obtained were as follows: mean LD = 69 ± 5.9 mm (range: 59-85 mm); mean APD = 40.2 ± 3.3 mm (range: 34-48 mm); mean TD = 15.5 ± 3.1 mm (range: 11-26 mm); and mean SMA = 43.8 ± 13.5 mm3 (range: 26-85.8 mm3). No statistically significant difference was observed between the healthy facial palsy groups's masseter muscles and reference values. As the latter, in denervated masseter muscles, no statistically significant difference was observed for APD value in contrast to LD, TD and SMA that showed statistically significant difference in comparison with control population (p < 0.05, CI 95%). Moreover fibro-adipose degeneration was consistently observed, with its degree being directly proportional to the denervation time. MMO and MBF mean values were, respectively, 54.75 mm in men, 44.4 mm in women and 705N. None of the latter showed a statistically significant difference with respect to the control population and the parameters present in the literature, indicating that masseter-facial neurorrhaphy is a safe and effective procedure for facial reanimation with good functional and aesthetic outcomes.

Follow-up program in head and neck cancer.

Follow-up program in head and neck cancer (HNC) is an important issue in patients management. It represents the major dilemma in daily practice clinic. Many guidelines have been published in order to better define the best clinical protocol, but a consensus has not been attained yet. We constructed a follow-up program based on specific primary subsite, to standardize patients surveillance after treatment of HNC.

Management of salivary gland malignant tumor: the Policlinico Umberto I, "Sapienza" University of Rome Head and Neck Unit clinical recommendations.

Salivary gland malignant tumor (SGMT) is a malignant disease requiring multidisciplinary approach. The rare incidence and the consequent lack of robust evidence-based medicine has called for a comprehensive update to draw recommendations for clinical practice. This paper is a summary of the XXX Head and Neck Unit guidelines regarding the management of SGMT. Recommendations include the indications for exclusive and adjuvant therapy, as well as metastatic management, for both major and minor SGMT.

Primary colonic lymphoma: An incidental finding in a patient with a gallstone attack.

We report a case of primary colonic lymphoma incidentally diagnosed in a patient presenting a gallbladder attack making particular attention on the diagnostic findings at ultrasound (US) and total body computed tomography (CT) exams that allowed us to make the correct final diagnosis. A 85-year-old Caucasian male patient was referred to our department due to acute pain at the upper right quadrant, spreaded to the right shoulder blade. Patient had nausea and mild fever and Murphy's maneuver was positive. At physical examination a large bulky mass was found in the right flank. Patient underwent to US exam that detected a big stone in the lumen of the gallbladder and in correspondence of the palpable mass, an extended concentric thickening of the colic wall. CT scan was performed and confirmed a widespread and concentric thickening of the wall of the ascending colon and cecum. In addition, revealed signs of microperforation of the colic wall. Numerous large lymphadenopathies were found in the abdominal, pelvic and thoracic cavity and there was a condition of splenomegaly, with some ischemic outcomes in the context of the spleen. No metastasis in the parenchimatous organs were found. These imaging findings suggest us the diagnosis of lymphoma. Patient underwent to surgery, and right hemicolectomy and cholecystectomy was performed. Histological examination confirmed our diagnosis, revealing a diffuse large B-cell lymphoma. The patient underwent to Cyclophosphamide, Hydroxydaunorubicin, Oncovin, Prednisone chemotherapy showing only a partial regression of the lymphadenopathies, being in advanced stage at the time of diagnosis.
