Diagnosis of benign paroxysmal positional vertigo in Emergency Department: Our experience.

The Benign Paroxysmal Positional Vertigo (BPPV) represents the first cause of peripheral vertigo in populations and it is determined by a displacement of otoconial fragments within the semicircular canals. Following the patient's head movements, these fragments, moving by inertia, incorrectly stimulate the canals generating vertigo. The BPPV is diagnosable by observing the nystagmus that is generated in the patient following the Dix-Hallpike maneuver used for BPPV diagnosis of vertical semi-circular canal, and, following the supine head yaw test used for lateral semi-circular canal. Correctly identifying the origin of this specific peripheral vertigo, would mean to obtain a faster diagnosis and an immediate resolution of the problem for the patient. In this context, this study aims to identify precise training activities, aimed at the application of specific diagnostic maneuverers for algorithm decisions in support of medical personnel. The evaluations reported in this study refer to the data collected in the Emergency Department of the Cardarelli Hospital of Naples. The results obtained, over a six-month observation period, highlighted the advantages of the proposed procedures in terms of costs, time and number of BPPV diagnoses.

Delayed recurrent nerve paralysis following post-traumatic aortic pseudoaneurysm.

Blunt trauma to the neck or to the chest are increasingly observed in the emergency clinical practice. They usually follow motor vehicle accidents or may be work or sports related. A wide pattern of clinical presentation can be potentially encountered. We report the uncommon case of a patient who was referred to our observation presenting with hoarseness and disphagia. Twenty days before he had sustained a car accident with trauma to the chest, neck and the mandible. Laryngoscopy showed a left recurrent laryngeal nerve palsy. Further otolaryngo-logical examination showed no other abnormality. At CT and MR imaging a post-traumatic aortic pseudoaneurysm was revealed. The aortic pseudoaneurysm was consequently repaired by implantation of an endovascular stent graft under local anesthesia. The patient was discharged 10 days later. At 30-days follow-up laryngoscopy the left vocal cord palsy was completely resolved. Hoarseness associated with a dilated left atrium in a patient with mitral valve stenosis was initially described by Ortner more than a century ago. Since then several non malignant, cardiovascular, intrathoracic disease that results in embarrassment from recurrent laryngeal nerve palsy usually by stretching, pulling or compression; thus, the correlations of these pathologies was termed as cardiovocal syndrome or Ortner's syndrome. The reported case illustrates that life-threatening cardiovascular comorbidities can cause hoarseness and that an impaired recurrent laryngeal nerve might be correctable.

Surgical treatment of metastases from cutaneous melanoma to the small intestine and the spleen. Case reports and review of the literature.

Cutaneous melanoma is found in the head and neck in 15% of patients, in the limbs in 22%, in the trunk in 40% and in occult sites in 16%. There is usually an interval of at least 3 years between the diagnosis of primary melanoma and the identification of metastases. Primary melanoma metastasizes most frequently to the lymph nodes (73.6% cases) and the lungs (71.3% cases). The small intestine and the spleen are the sites of 36.5% and 30.6% respectively of the gastrointestinal metastases from melanoma. The cases reported provide evidence of the effect radical resection in patients with gastrointestinal metastases can have on survival. The cases and a review of the literature suggest that a careful and multidisciplinary follow-up is of crucial importance since it is the only means of identifying metastases when they can be still cured with surgical treatment.

[Prognostic and curative value of sentinel node in breast cancer. A 377 patients experience]. / Valore prognostico e curativo del linfonodo sentinella nel trattamento chirurgico del cancro della mammella. Analisi di 377 pazienti.

Sentinel node is defined as the first lymphnode receiving limphatic drain from the breast. Several studies show a very low recurrence rate to axillary and locoregional nodes in sentinel node negative patients who did not undergo axillary dissection. Our study aims to verify if complete axillary dissection could be replaced by sentinel node biopsy (SNB) in the staging and treatment of breast cancer. From January 2005 to December 2008, 377 patients (mean age 57.63) underwent SNB in the General Surgery unit of "San Giuseppe Moscati" Hospital in Avellino (Italy). All the patients underwent SNB with local anesthesia. Histologic studies were performed using GIVOM protocol (Veneto Breast cancer interdisciplinary group). Sixty five patients (17.2%) underwent a radical mastectomy with SNB and 312 (82.6%) patients underwent a quadrantectomy with SNB. Of this last group, 178 (47.2%) underwent a superior quadrant excision with SNB, 77 (20.4%) an inferior quadrant excision with SNB and 57 (15.1%) a central quadrant excision with SNB. Ductal carcinoma represented 57.3% of the tumous detected, lobular carcinoma was diagnosed in 16.4% of the cases, intraductal microinvasive carcinoma in 10.3%, ductal carcinoma in situ in 5.8% while the other histotypes were diagnosed in 10% of the tumours. All SNB+ patients (34.5%) underwent a radical axillary dissection in general anesthesia. Sixty nine (53%) patients were diagnosed with axillary node metastasis, after axillary dissection Micrometastasis resulted in 19.6% of the excised patients. The prevalence of axillary node metastasis was 26.4% (581/2198), while the incidence was 34.5% (130/377). The first axillary lymphnodes level was metastasized in 65.8% patients who had undergone an axillary dissection, level I and II in 268% and all the levels in 7.4%. Only one case (0.4%) of nodal metastatic recurrence has been diagnosed in patients who had undergone SNB alone, after a mean follow-up of 28.5 month. Apart from showing a very high diagnostic and staging accuracy, the high level of SN detection associated with a high predictive rate underline a lower complications rate if compared to complete nodal dissection.

Surgical therapy of goiter plunged in the mediastinum. Considerations regarding our experience with 165 patients.

Thyroid goiter is called plunged when, starting from the cervical region, it grows in the anterior-superior mediastinum to a depth of more than 2 cm. The highest frequency (48.44%) is evident in the age range from 60 to 70. From February 2002 to August 2005, performed 133 (80.6%) near total thyroidectomies, 26 total thyroidectomies (15.7%), 4 lobectomies (2.4%) and 2 (1.2%) totalisations of recurrences for plunged goiter in the 7th Division of General Surgery of the Second University of Naples. The goiters were classified using Lamke and Ferrante's topographical classification, which distinguishes between prevascular and retrovascular cervico-mediastinal goiters depending on the position assumed by the part plunged in the mediastinum in relation to the vascular layer of the epiaortic trunks. Retrovascular goiters are further subdivided into: pre-tracheal, laterovisceral and retrovisceral goiters depending on the relation to the trachea, oesophagus and epiaortic trunks. Among the patients who underwent near total thyroidectomy, there were 3 cases of permanent hypocalcaemia, 7 (7.2%) of temporary hypocalcaemia and only 1 (0.6%) monolateral temporary recurrent nerve lesion. Among those who underwent total thyroidectomy there was 1 case (0.6%) of temporary hypocalcaemia, and 1 (0.6%) of permanent hypocalcaemia. Postoperatively we also observed 3 cases (1.8%) of haemorrhage and 3 (1.8%) transfers to intensive care for respiratory insufficiency; 1 of these patients died 25 days after the operation. Ligature of the inferior and superior thyroid artery near the thyroid capsule protects the vascularisation of the parathyroid glands as well as the recurrent nerve and its division branches.
