Prevalence and diagnosis of vestibular disorders in children: a review.

OBJECTIVES To systematically review and discuss the main pathologies associated with vertigo and dizziness in children, paying particular attention to recent advances in diagnosis and therapy. METHODS One appropriate string was run on PubMed to retrieve articles dealing with the topics mentioned above. A cross-check was performed on citations and full-text articles found using the selected inclusion and exclusion criteria. A non-comparative meta-analysis concerning the rate of singular vertiginous forms was performed. RESULTS Ten articles were identified comprising a total of 724 subjects. Overall, the articles we analyzed indicated benign paroxysmal vertigo of childhood (18.7%) and migraine-associated vertigo (17.6%) as the two main entities connected with vertigo and dizziness in children. Head trauma (14%) was the third most common cause of vertigo. The mean (95% CI) rate of every vertiginous form was also calculated in relation to the nine studies analyzed with vestibular migraine (27.82%), benign paroxysmal vertigo (15.68%) and vestibular neuritis (9.81%) being the three most common forms. There appeared to be a paucity of recent literature concerning the development of new diagnostic methods and therapies. CONCLUSIONS On the basis of the literature study, when evaluating a young patient with vertigo and dizziness, the otolaryngologist should be aware that, in children, these symptoms are often connected to different pathologies in comparison to the entities observed in the adult population.

Outcomes and complications in superior semicircular canal dehiscence surgery: A systematic review.

Superior semicircular canal dehiscence (SSCD) represents a rare condition that may be associated to some particular symptoms as vertigo, autophony, and Tullio phenomenon. In those patients who present severe symptoms surgical treatment is required. Middle fossa craniotomy and transmastoid approaches are both described. Concerning repairing techniques, plugging and/or resurfacing are typically used to close the defect. Our aim was first to analyze the overall outcomes and complications of this surgery. Our second aim was to make a comparison between the different surgical modalities to investigate the eventual advantages and disadvantages.

Preoperative Predictors of Successful Surgical Treatment in the Management of Parapneumonic Empyema

BACKGROUND Video-assisted thoracoscopic surgery (VATS) and thoracotomy are the main surgical options for treating parapneumonic empyema. The choice of either operation depends on many preoperative features, including the patients condition, clinical and radiologic findings, and pleural fluid characteristics. The identification of the combination of those preoperative findings that will allow surgeons to select the appropriate approach for a successful operation (VATS or thoracotomy) could be of great interest in clinical settings. METHODS We retrospectively reviewed a series of 97 patients who had undergone successful VATS or thoracotomy for parapneumonic empyema; in all cases, the operation had begun through VATS and was changed to a thoracotomy if a complete decortication was needed. Preoperative clinical, radiologic, and laboratory features were compared between the two groups to search for differences that might serve as predictive factors for either operation. Perioperative findings were also analyzed. RESULTS The operation was accomplished by VATS in 40 patients (41%), and conversion to thoracotomy was necessary in 57 (59%). Significant predictive factors for conversion were a prolonged delay from diagnosis to operation, the presence of fever and of pleural thickness on computed tomography (CT) images. The 25 patients who presented with these three features were cured by thoracotomy. The operative time and postoperative complication rate were significantly higher for the thoracotomy patients. CONCLUSIONS Some preoperative features can help the surgeon to better select patients for the appropriate operation. Delayed operation, fever, and pleural thickness can be used to predict the likelihood of conversion to thoracotomy.

Clinical presentation and treatment outcomes of thyroglossal duct cysts: a systematic review

The aim of the present review was to analyze the main clinical signs and symptoms observed in patients with thyroglossal duct cysts (TGDCs). Secondarily we investigated the outcomes following the different types of treatment of TGDCs in children and adults. Three selected strings were run on the PubMed database to retrieve articles on these topics. A double cross-check was performed on citations and full-text articles were identified using the study inclusion and exclusion criteria. A meta-analysis was performed of the data obtained. Overall, 356 articles were identified; 24 (comprising a total of 1371 subjects) satisfied the inclusion and exclusion criteria. On the basis of the meta-analysis, the presence of a neck cystic mass was the main clinical presentation of TGDCs, with a mean rate of 75% (95% confidence interval 72-79%). The mean local wound infection rate was 4% (95% confidence interval 3-6%), this being the most frequent complication following treatment. The mean rate of overall recurrence was 11% (95% confidence interval 9-14%). The Sistrunk procedure appears to be the better choice for the therapy of TGDCs to avoid recurrences. Further studies on larger cohorts of patients regarding the minimally invasive treatment options would be helpful to elucidate and endorse their utilization in selected cases.

The role of antibiotic therapy and nasal packing in septoplasty.

Both systemic antibiotic therapy and nasal packing are used frequently in septoplasty. Nevertheless, there is still great disagreement among authors around the real advantages with regard to the efficacy of both of these procedures in septal surgery. The aim of the present review was to evaluate the more recent data published on this topic. One appropriate string was run on PubMed to retrieve articles dealing with the topics mentioned above. A double cross-check was performed on citations and full-text articles found using the selected inclusion and exclusion criteria. Overall, the articles we analyzed indicated the poor utility of routine antibiotic therapy and nasal packing during septoplasty, the latter procedure producing more complications than advantages. In conclusion, on the basis of the recent literature, the use of systemic antibiotic prophylaxis and nasal packing in septal surgery seems to be a non-rational procedure.

Factors affecting outcome in ocular myasthenia gravis

ABSTRACT Aim of the study: 50%–60% of patients with ocular myasthenia gravis (OMG) progress to generalized myasthenia gravis (GMG) within two years. The aim of our study was to explore factors affecting prognosis of OMG and to test the predictive role of several independent clinical variables. Materials and methods: We reviewed a cohort of 168 Caucasian patients followed from September 2000 to January 2016. Several independent variables were considered as prognostic factors: gender, age of onset, results on electrophysiological tests, presence and level of antibodies against acetylcholine receptors (AChR Abs), treatments, thymic abnormalities. The primary outcome was the progression to GMG and/or the presence of bulbar symptoms. Secondary outcomes were either achievement of sustained minimal manifestation status or worsening in ocular quantitative MG subscore (O-QMGS) or worsening in total QMG score (T-QMGS), assessed by Myasthenia Gravis Foundation of America (MGFA) quantitative scores. Changes in mental and physical subscores of health-related quality of life (HRQoL) were assessed with SF-36 questionnaire. Variance analysis was used to interpret the differences between AChR Ab titers at different times of follow up among the generalized and non-generalized patients. Results: Conversion to GMG occurred in 18.4% of patients; it was significantly associated with sex, later onset of disease and anti-AChR Ab positivity. Antibody titer above the mean value of 25.8 pmol/mL showed no significant effect on generalization. Sex and late onset of disease significantly affected T-QMGS worsening. None of the other independent variables significantly affected O-QMGS and HRQoL. Conclusions: Sex, later onset and anti-AChR Ab positivity were significantly associated with clinical worsening.

Disease presentation, treatment and survival for Italian colorectal cancer patients: a EUROCARE high resolution study

We analysed presentation, treatment and survival in a representative population-based sample of 3753 Italian colorectal cancer cases, diagnosed 2003-05: 70% were >65 years, 44% stage I-II, 27% stage IV and 92% received surgery. Chemotherapy was given to 58% of stage III colon cases, radiotherapy to 25% of rectal cases. Four percent of surgical cases underwent endoscopic polypectomy, and in 57% ≥11 lymph nodes were examined. Five-year relative survival was good (60%), independent of sex and site. Adherence to treatment guidelines was satisfactory, but wider use of faecal blood testing and colonoscopy will anticipate stage at diagnosis and likely improve survival.

Management of rectal cancers in relation to treatment guidelines: a population-based study comparing Italian and French patients

BACKGROUND Few studies have investigated rectal cancer management at the population level. We compared how rectal cancers diagnosed in Italy (2003-2005) and France (2005) were managed, and evaluated the extent to which management adhered to European guidelines. METHODS Samples of 3938 Italian and 2287 French colorectal cancer patients were randomly extracted from 8 and 12 cancer registries respectively. Rectal cancer patients (860 Italian, 559 French) were analysed. Logistic regression models estimated odds ratios (ORs) of being treated with curative intent, receiving sphincter-saving surgery, and receiving preoperative radiotherapy. RESULTS Similar proportions of Italian and French patients were treated with curative intent (70% vs. 67%; OR=0.92 [0.73-1.16]); the respective proportions receiving sphincter-saving surgery were 21% and 33% (OR=1.15 [0.86-1.53]). In about 50% of those treated with curative intent, ≥ 12 lymph nodes were harvested in both countries. The proportion receiving postoperative radiotherapy was higher in Italy than in France (25% vs. 11%, p<0.01), but French patients were more likely to receive preoperative radiotherapy (52% vs. 21%; OR=4.06 [2.79-5.91]). CONCLUSION The proportions of patients receiving preoperative radiotherapy and the numbers of lymph nodes sampled were low in both countries. Centralising treatment and potentiating screening would be practical ways of improving outcomes and adhering to guidelines.

GD2 expression in breast cancer

Breast cancer (BC) is a heterogeneous disease, including different subtypes having diverse incidence, drug-sensitivity and survival rates. In particular, claudin-low and basal-like BC have mesenchymal features with a dismal prognosis. Disialoganglioside GD2 is a typical neuroectodermal antigen expressed in a variety of cancers. Despite its potential relevance in cancer diagnostics and therapeutics, the presence and role of GD2 require further investigation, especially in BC. Therefore, we evaluated GD2 expression in a cohort of BC patients and its correlation with clinical-pathological features. Sixty-three patients with BC who underwent surgery without prior chemo- and/or radiotherapy between 2001 and 2014 were considered. Cancer specimens were analyzed by immunohistochemistry and GD2-staining was expressed according to the percentage of positive cells and by a semi-quantitative scoring system. Patient characteristics were heterogeneous by age at diagnosis, histotype, grading, tumor size, Ki-67 and receptor-status. GD2 staining revealed positive cancer cells in 59% of patients. Among them, 26 cases (41%) were labeled with score 1+ and 11 (18%) with score 2+. Notably, the majority of metaplastic carcinoma specimens stained positive for GD2. The univariate regression logistic analysis revealed a significant association of GD2 with triple-receptor negative phenotype and older age (> 78) at diagnosis. We demonstrate for the first time that GD2 is highly prevalent in a cohort of BC patients clustering on very aggressive BC subtypes, such as triple-negative and metaplastic variants.
