Giant deep lobe parotid tumor removal via total parotidectomy without mandibulotomy. A simple and safe technique
The transmandibular route is often combined with the transparotid-transcervical approach when extensive surgical field exposure is required, as in the case of deep parotid lobe tumors measuring over 4 cm in size. This procedure implies great morbidity an
Odontogenic maxillary sinusitis and fungus ball development secondary to a dental root retained for more than 25 years. : a case report
The displacement of a dental root fragment into the maxillary sinus is a serious complication of tooth extraction that can give rise to maxillary sinusitis. The condition can become chronic if the intrasinusal foreign body is not promptly removed, and As
Multicentric recurrent parotid pleomorphic adenoma in a child
Mixed tumours of the parotid gland are rare in childhood and recurrence of this tumour is infrequent. Some authors report a higher rate of recurrence with some histological subtypes, like hypocellular variant. Female sex and young age at initial treatment are also risk factor for recurrence. Also the first surgical treatment, tumour enucleation or parotidectomy, has been implicated as a cause for recurrence. We present a case of a multicentric doubly recurrent parotid pleomorphic adenoma, 7 and 14 years after tumour enucleation, in a 9-year-old child. All the nodules resected showed the hypocellular variant of pleomorphic adenoma. We consider the relationships between the choice of treatment, the histologic subtypes of pleomorphic adenomas and multifocal tumours and recurrence. In this case, we believe the recurrence was related to surgical enucleation previously performed and the hypocellular histological subtype. We conclude that tumour enucleation is a risk factor for recurrence and total parotidectomy is the treatment of choice for pleomorphic parotid adenoma also in childhood
Axonemal Symmetry Break, a New Ultrastructural Diagnostic Tool for Primary Ciliary Dyskinesia?
Diagnosis testing for primary ciliary dyskinesia (PCD) requires a combination of investigations that includes study of ciliary beat pattern by high-speed video-microscopy, genetic testing and assessment of the ciliary ultrastructure by transmission electron microscopy (TEM). Historically, TEM was considered to be the 'gold standard' for the diagnosis of PCD. However, with the advances in molecular genetic techniques, an increasing number of PCD variants show normal ultrastructure and cannot be diagnosed by TEM. During ultrastructural assessment of ciliary biopsies of patients with suspicion of PCD, we observed an axonemal defect not previously described that affects peripheral doublets tilting. To further characterize this defect of unknown significance, we studied the ciliary axonemes by TEM from both PCD-confirmed patients and patients with other sino-pulmonary diseases. We detected peripheral doublets tilting in all the PCD patients, without any significant difference in the distribution of ciliary beat pattern or mutated gene. This defect was also present in those patients with normal ultrastructure PCD subtypes. We believe that the performance of axonemal asymmetry analysis would be helpful to enhance diagnosis of PCD
Posterior Lingual Abscess; Report of Two Cases
The lingual abscess is rare due to several protective mechanisms against infection in this location. Concretely, the abscess in the base of the tongue (posterior lingual abscess) is even more exceptional. Its prompt detection is crucial to avoid potentially fatal airway complications. To familiarize physicians with this condition, we report 2 cases of posterior lingual abscess. Both were referred to our emergency department due to minor oropharyngeal complaints. Finally, both were diagnosed and required surgical drainage. The clinical evolution was successful: both were discharged in less than 72 hours and follow-up one week later confirmed clinical recover
Malignant fibrohistiocytoma of the parotid region : report of a case
Most salivary gland tumors are benign, malignant lesions accounting for 15-30% of the total. The most frequent site of salivary gland neoplasms is the parotid gland (80% of all cases). We present a case of malignant fibrohistiocytoma with atypical features due to its location (in the parotid region), size and rapid growth. Generally, this type of tumor arises in the lower limbs and in the abdomen. When located in the parotid gland, these lesions appear as a firm, slow growing and painless mass. Due to the low frequency of such lesions and their clinical behavior, the imaging study and fine-needle aspiration biopsy findings tend to diagnose them as pleomorphic adenoma. The definitive diagnosis requires microscopic study of the resection piece using immunohistochemical techniques. The treatment of choice is surgery, occasionally associated to radiotherapy. The success of treatment is dependent upon complete resection of the tumor - long term follow-up being necessary due to the risk of recurrence or distant metastasis
Fallopian Canal Meningocele Causing Cerebrospinal Fluid Rhinorrhoea
Fallopian canal meningocele is an extremely rare cause of cerebrospinal fluid rhinorrhoea. Also, due to complex anatomical relations and a lack of experience, its management remains a challenge. Here we report a case focusing on its clinical course, radiological features, and management
Molecular and Clinical Predictors of Quality of Life in Chronic Rhinosinusitis with Nasal Polyps
Factors influencing the quality of life (QoL) of patients with chronic rhinosinusitis with nasal polyposis (CRSwNP) are poorly understood. We set out to determine the predictive factors on patients' QoL using the Sino-Nasal Outcome Test-22 (SNOT-22); (2) Methods: An ambispective analysis of data from patients diagnosed with CRSwNP in our institution. All the patients underwent a nasal polyp biopsy and completed the SNOT-22 questionnaire. Demographic and molecular data as well as the SNOT-22 scores were collected. Patients were classified in six subgroups considering the presence of asthma, non-steroidal drugs (NSAID) intolerance and corticosteroid resistance; (3) Results: The mean SNOT-22 score was 39. Considering the clinical parameters, the SNOT-22 value was significantly associated with NSAID intolerance (p = 0.04) and the endoscopic polyp score (p = 0.04). A high SNOT-22 value was also correlated with high tissue eosinophilia (p = 0.01) and high IL-8 expression; (4) Conclusions: Eosinophilia, IL-8 expression and NSAID intolerance can be used as predictors of worse QoL in patients with CRSwNP
Dizziness Evaluation and Characterisation of Patients with Posterior Circulation Stroke in the Emergency Department; a Case Series Study
Introduction: Â Dizziness is a common scenario in the Emergency Departments (EDs). Among dizziness underlying causes, the posterior circulation stroke is especially relevant due to its mobimortality and concerning misdiagnosis rates. Therefore, we conducted this study to assess dizziness evaluation and baseline characteristics of patients with PS in the ED.
Methods: We conducted a 3-year retrospective observational study on PS cases confirmed by magnetic resonance imaging (MRI). Concretely, we analysed the demographic profile of these patients, the initial PS clinical presentation, and diagnostic workup (with emphasis on dizziness evaluation) performed at the ED.
Results: During the study period, 85 cases were registered. Risk factors for cardiovascular disease were present in 85.5% and previous visits to the ED due to dizziness were recorded in 16.5%. The main clinical presentation was dizziness, concretely as an acute vestibular syndrome (38.8%) with additional neurological signs or symptoms (80%). Evaluation by the otolaryngologist on call was requested in less than 10% of the cases and included the HINTS protocol use with a sensitivity of 100% for central nervous system underlying causality. A brain CT study was always performed with a sensitivity of 27%. However, 96.47% of patients were primarily admitted to the Neurology hospitalization ward and MRI was always performed in a mean time of 3.21 days confirming the diagnosis.
Conclusions: Dizziness is the most frequent symptom of PS. Patients usually present an AVS (associated with additional N-SS or not) and HINTS bedside examination is the most adequate protocol to differentiate a PS from other AVS causes until the diagnostic confirmation via MRI. Interestingly, mainly otolaryngologists seem to use HINTS. However, the use of CT is widespread despite its poor value
