Emerging reports suggest that new onset of smell or taste loss are potential early clinical markers of SARS-CoV-2 infection, but it remains unclear as to what extent. Therefore, the purpose of this ...study is to systematically assess the prevalence of self-reported altered sense of smell or taste in patients with confirmed SARS-CoV-2 infection, overcoming the limitations of individual studies by meta-analysis of pooled data.
The databases Medline, Embase, Web of Science, Scopus and MedRxiv's set were searched from inception to the 4th May 2020. This study was conducted following the PRISMA checklist.
18 studies met the eligibility criteria out of the 171 initially screened citations. The overall prevalence of alteration of the sense of smell or taste was 47% , but estimates were 31% and 67% in severe and mild-to-moderate symptomatic patients, respec- tively. The loss of smell and taste preceded other symptoms in 20% of cases and it was concomitant in 28%.
Based on this meta-analysis, we recommend self-isolation and testing, where possible, for patients complaining smell or taste impairment during COVID-19 pandemic in order to prevent spread of disease and propose the inclusion of loss of smell and taste as recognized symptoms of SARS-CoV-2 in the World Health Organization and other relevant regulatory body's lists.
Using an age and gender matched-pair case-control study, we aimed to estimate the long-term prevalence of psychophysical olfactory, gustatory , and chemesthesis impairment at least one year after ...SARS-CoV-2 infection considering the background of chemosensory dysfunction in non-COVID-19 population.
This case-controlled study included 100 patients who were home-isolated for mildly symptomatic COVID-19 between March and April 2020. One control regularly tested for SARS-CoV-2 infection and always tested negative was matched to each case according to gender and age. Chemosensory function was investigated by a comprehensive psychophysical evaluation including ortho- and retronasal olfaction and an extensive assessment of gustatory function. Differences in chemosensory parameters were evaluated through either Fisher’s exact test or Kruskal-Wallis test.
The psychophysical assessment of chemosensory function took place after a median of 401 days from the first SARS-CoV-2 positive swab. The evaluation of orthonasal smell identified 46% and 10% of cases and controls, respectively, having olfactory dysfunction, with 7% of COVID-19 cases being functionally anosmic. Testing of gustatory function revealed a 27% of cases versus 10% of controls showing a gustatory impairment. Nasal trigeminal sensitivity was significantly lower in cases compared to controls. Persistent chemosensory impairment was associated with emotional distress and depression.
More than one year after the onset of COVID-19, cases exhibited an excess of olfactory, gustatory , and chemesthesis disturbances compared to matched-pair controls with these symptoms being associated to emotional distress and depression.
There is mounting evidence that a new onset of altered sense of smell or taste is related to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. In order to allow patients to ...recognize symptoms indicative of SARS-CoV-2 infection and self-isolate at the earliest opportunity, self-reported loss of smell and taste have greater value in controlling disease transmis- sion than psychophysical testing, which is not widely available outside of highly specialized clinics.
The objective of this study was to ascertain the effects of competitive noise on second language perception skills of sequentially bilingual children and to compare the results with those relating to ...matched monolingual peers. Fifteen bilingual immigrant children (aged 6-10 years) (BL) learning through their second language (L2), which was Italian, were matched with 15 peers who only spoke Italian (IO). All immigrant children had arrived in Italy and were exposed to L2 after their 4
year of life. The speech-to-noise ratio (SNR) needed to obtain 50% intelligibility - the speech reception threshold (SRT) - for Italian words was measured against the Italian version of ICRA noise, using an adaptive method. Moreover, presentation of phrases against a contralateral continuous discourse (informational masking) was carried out to exclude possible biases due to differences in memory, attention, or other central auditory processing disorders between groups. The SNR was -2.7 dB (SD 1.7; range: -5.5 to + 0.9) for the BL group and -5.3 dB (SD 2.3; range: -8.8 to -0.9) for the IO group (p < 0.01). With contralateral continuous discourse presentation the SNR were -32.8 dB (SD 2.4; range: -36.1 to -28.2) for the BL group and -27.8 dB (SD 2.1; range: -31.7 to -24.1) for the OI group (p < 0.01). Even sequential bilingual individuals exposed to L2 at 4 years old had worse speech perception in noise than their matched IO peers. On the other hand, the BL group demonstrated superior divided attention skills in tests with competitive contralateral discourse (p < 0.01).
Endolymphatic sac tumour (ELST) is infrequent, as emerges from small series reported in the literature. It is a slow-growing malignancy with local aggressiveness and a low risk of distant metastases. ...It is often misdiagnosed because of the late onset of symptoms and difficulty in obtaining a biopsy. Its frequency is higher in von Hippel-Lindau (VHL) disease (a genetic systemic syndrome involving multiple tumours), with a prevalence of around 25%. The diagnosis is based on radiology, with specific patterns on contrast-enhanced MRI and typical petrous bone erosion on bone CT scan. Our experience of ELST in the years between 2012-2015 concerns 7 cases, one of which was bilateral, in patients with VHL disease. Four of the 7 patients underwent 5 surgical procedures at our institution. Each case is described in detail, including clinical symptoms, and the intervals between symptom onset, diagnosis and therapy. Postoperative morbidity was low after early surgery on small tumours, whereas extensive surgery for large tumours was associated with loss of cranial nerve function (especially VII, IX, X). The critical sites coinciding with loss of neurological function were the fallopian canal, jugular foramen, petrous apex and intradural extension into the posterior cranial fossa. Early surgery on small ELST is advocated for patients with VHL disease, in whom screening enables a prompt diagnosis and consequently good prognosis.
Abstract The aim of this case report is to present an original conservative technique for the transnasal endoscopy-assisted extraction of an ectopic upper third molar associated with a dentigerous ...cyst occupying the whole maxillary sinus by means of combined lower and middle meatotomies. The proposed technique is a viable, minimally-invasive alternative to the Caldwell–Luc operation (with or without the repositioning of a bone lid), and also to endoscopic middle meatal antrostomy in cases where this would be unable to ensure adequate access because of the position and size of the ectopic tooth and associated cyst.
Abstract Background In scientific literature exist fewer case series regarding endoscopic treatment of paediatric cerebrospinal fluid fistulas. Compared to craniotomy endoscopic repair does not reach ...wider consent even if craniotomy carries higher complications rate. Objective The aim of the present study was to report our institutional experience on paediatric cerebrospinal fluid leak to demonstrate the safety and efficacy of the endoscopic approach in a variety of cases. Methods Clinical records of all paediatric patients who underwent endoscopic repair of anterior and middle fossa skull base defects are reviewed for several parameters. Results 10 patients were enrolled, 6 males and 4 females with a mean age of 10 years. The aetiology of the leak was congenital in 2 cases, trauma-induced in 6 cases and iatrogenic in 2 cases. In all the cases the defect was localized by computed tomography. Remedial was obtained using multiple grafts technique with autologous materials during a single procedure in all but one case, this one case requiring a second operation for delayed recurrence. The mean follow-up duration is 36 months. Conclusion CSF fistulas can be approached in paediatrics of any age with high success and low complications rate using the endonasal technique.
Epistaxis is extremely common in children. Although rare, the presence of an intranasal mass as a cause of bleeding should be ruled out in patients with recurrent or massive epistaxis. We present a ...patient whose recurrent nose-bleeding had been due to a nasopharyngeal mass.
Case report with relevant literature review.
A 15-year-old girl with a history of sudden posterior nasal bleeding was diagnosed with thyroid-like low-grade nasopharyngeal papillary adenocarcinoma of the nasopharynx. A type II nasopharyngeal endoscopic resection was performed with an excellent outcome at 30-months follow-up. The literature review on the topic disclosed only five other paediatric cases, none of which presented with epistaxis.
Recurrent epistaxis may infer the presence of nasopharyngeal malignant neoplasms, even in children. To our knowledge, this represents the sixth case in the literature of a paediatric low-grade nasopharyngeal adenocarcinoma and the first presenting with massive epistaxis. The possibility of such a finding should be kept in mind when evaluating children with massive epistaxis.
Il carcinoma del sacco endolinfatico è un tumore molto raro come evidente dai dati presenti in letteratura ove anche centri di esperienza riferiscono tuttavia casistiche limitate. E un tumore ...maligno a lenta crescita, con tendenza allinvasione locale e scarsa tendenza alla disseminazione metastatica. Linsorgenza spesso tardiva dei sintomi e la difficoltà ad eseguire indagini bioptiche a livello della sede di origine, parete posteriore della rocca, ha reso la diagnosi di questo tumore spesso difficile, nonostante si riconoscano attualmente dati radiologici patognomonici della neoplasia. Patterns tipici di presentazione sono evidenziabili alla RM con mezzo di contrasto e alla TC per osso a strato sottile, rendendo nella maggior parte dei casi possibile la diagnosi radiologica. Lincidenza del tumore del sacco endolinfatico è maggiore nei pazienti affetti da sindrome di von Hippel Lindau (VHL), con una frequenza del 25% che fa parte del quadro sindromico. Negli anni dal 2012 al 2015 abbiamo osservato 7 casi, uno di essi con manifestazione della patologia bilaterale, tutti affetti da VHL. Quattro tra questi sono stati sottoposti a chirurgia presso il nostro centro per un totale di 5 procedure chirurgiche. Ogni caso è stato descritto dettagliatamente analizzando sintomi, intervallo tra comparsa dei sintomi, diagnosi e terapia. Non vi è stata morbidità post-operatoria aggiuntiva nei pazienti in cui la diagnosi e la terapia sono state precoci, mentre la gestione di tumori localmente avanzati è stata associata a deficit neurologici postoperatori, in particolare del VII, IX e X nervo cranico. I siti anatomici critici di coinvolgimento della malattia che hanno coinciso con un pianificato rischio di danno neuronale sono risultati essere il canale di Falloppio, il forame giugulare, lapice della rocca petrosa. Lestensione intradurale nella fossa cranica posteriore è stato un altro elemento caratterizzante i tumori in stadio avanzato. I tumori del sacco endolinfatico che lo screening permette di evidenziare precocemente nei pazienti VHL, hanno buona prognosi quando affrontati precocemente, compatibilmente con le esigenze terapeutiche della malattia di base.
