ABSTRACT

INTRODUCTION: The objective was to evaluate health care providers' (HCP) adherence to and efficacy of varicella post-exposure prophylaxis (PEP) recommendations. It was an observational, prospective, multicenter study set in Ile-de-France, France.

METHODS: All children under 18 with a cancer diagnosis, currently or within 3months of receiving cancer treatment, regardless of varicella zoster virus (VZV) serostatus or previous personal history of varicella, were eligible. Study participants with significant exposure were reviewed prospectively for PEP indications. Main outcome measures were the percentage of exposure situations for which HCP were guideline-compliant, the proportion of available VZV serostatuses and the incidence of breakthrough varicella after different PEP approaches.

RESULTS: A total of 51 patie nts from 15 centers were enrolled after 52 exposure episodes. Median age at exposure was 5 years (range, 1-15). Exposure within the household led to 38% of episodes. Prophylactic treatment consisted in specific anti-VZV immunoglobulins (V-ZIG) (n=19) or in oral aciclovir (n=15). No prophylactic treatment was given for 18 patients (in compliance, n=16). In compliance with guidelines, 17 patients received V-ZIG, 11 did not develop varicella (65%, [95% CI, 39-90%]); 15 received aciclovir, 13 did not develop varicella (87%, [95% CI, 67-100%]). Breakthrough varicella occurred in 11 patients, with simple clinical course in all cases; in 8/47 (17%) episodes when PEP was guideline-compliant versus 3/5 (60%) when not.

DISCUSSION: Recommendations have been respected and are efficient. PEP needs to be standardized and a study carried out to define the optimal approach. Anti-VZV immunization of seronegative family members should be encouraged.

Surg Radiol Anat. 2022 Jan 30. doi: 10.1007/s00276-021-02871-x. Online ahead of print.

ABSTRACT

PURPOSE AND BACKGROUND: Previous studies have identified variations regarding the morphology and location of the carotid sinus, a phenomenon still not commonly approached or studied on computed tomography angiography (CTA). Detailed characterization of the carotid sinus was performed on CTAs, determining its position, diameter and length.

METHODS: The study group included 43 patients with disease-free carotid trunks subjected to cervical CTA. We measured the terminal caliber of the common carotid artery (CCA), as well as the calibers of the internal (ICA) and external carotid arteries (ECA) at their origin. The diameters were correlated with the location and the shape of the carotid sinus. We also measured the length of the sinus dilatation (carotid bulb), in regard to its location on the terminal branches of the common carotid artery.

RESULTS: Mean diameters of the studied arteries were 7.39 ± 1.04 mm for the CCA, 6.71 ± 1.49 mm for the ICA and, respectively, 4.27 ± 0.75 mm for the ECA. The classical position of the carotid sinus was seen in 80% of cases, the rest being considered anatomical variants. The length of the carotid bulb on the ICA was 9.99 ± 2.22 mm, showing variability between genders.

CONCLUSIONS: The carotid sinus does not always extend to the ICA, presenting different distribution patterns that might be relevant in sinu s pathology from a clinical point of view, respectively from a surgical point of view during invasive or minimally invasive interventions on the carotid axis.

xlomafota13 shared this article with you from Inoreader

Eur Arch Otorhinolaryngol. 2022 Jan 30. doi: 10.1007/s00405-021-07210-9. Online ahead of print.

ABSTRACT

PURPOSE: This study aims to analyze whether the consumption of salted fish and processed foods increases the risk of nasopharyngeal carcinoma by analyzing the relevant case-control or cohort design.

METHODS: Major databases such as PubMed, ScienceDirect, Embase and Cochrane Library were searched to conduct related studies. In addition, Newcastle-Ottawa scale was employed for assessing the quality of articles. Random-effect model was utilized for meta-analysis. Total relative risk (RR) and 95% confidence interval (95% CI) were calculated.

RESULTS: Dose response showed a consistent linear relationship between the intake of salted fish and processed foods and the risk of nasopharyngeal carcinoma. In salted fish, the summary RR was 1.23 (1.04-1.47) for low intake and 1.45 (1.19-1.76) for high intake. For processed meat, low intake was 1.33 (1.09-1.62) and high intake was 1.65 (1.35-2.02). Low intake of processed vegetables was 1.28 (1.05-1.55) and high intake was 1.45 (1.17 -1.79) for high intake. Significant heterogeneity existed in all data but decreased in some subgroups after subgroup analysis.

CONCLUSION: Salted fish and processed foods are risk factors for increasing nasopharyngeal carcinoma, but they have different risk characteristics due to different intakes, different stages, and different types.

xlomafota13 shared this article with you from Inoreader

Eur Arch Otorhinolaryngol. 2022 Jan 30. doi: 10.1007/s00405-021-07228-z. Online ahead of print.

ABSTRACT

BACKGROUND: Difficult-to-treat rhinosinusitis (DTRS) seriously affects the quality of work and life of patients, and the cause is still unclear. We aimed to explore the association between the glucocorticoid receptor (NR3C1) gene polymorphisms and DTRS.

METHODS: A nested case-control study was conducted. The exons of NR3C1 gene were sequenced by an ABI 9700 DNA analyzer in 30 DTRS patients and 70 matched chronic rhinosinusitis (CRS) patient with good outcome (non-DTRS). The genotypic and allele frequencies were calculated and linkage disequilibrium was analyzed.

RESULTS: The three SNPs showed a significant difference between the DTRS and non-DTRS groups. In allelic model analysis, we found that the allele "C" of rs6196, the allele "A" of rs258751, and the allele "T" of rs6194 were associated with increased the risk of DT RS (all p < 0.05). In addition, the haplotype CAT of the 3 SNPs was detected to be significantly associated with DTRS risk (p = 0.001), while the haplotype TGC was associated with the decreased risk of DTRS (p = 0.008).

CONCLUSION: NR3C1 gene polymorphisms are significantly associated with the DTRS.

xlomafota13 shared this article with you from Inoreader

Eur Ann Otorhinolaryngol Head Neck Dis. 2022 Jan 26:S1879-7296(22)00004-7. doi: 10.1016/j.anorl.2022.01.002. Online ahead of print.

ABSTRACT

OBJECTIVE: To compare the prevalence of cardiovascular risk factors (CVRF) in patients with superior vestibular neuritis (SVN) versus the general French population, and to examine the possibility of vascular etiology in acute superior vestibular deficit.

MATERIAL AND METHODS: A single-center retrospective study compared the prevalence of hypercholesterolemia, hypertension, diabetes, smoking, cardiovascular disease and atrial fibrillation between patients with SVN and the French general population. Inclusion criteria comprised: rotatory vertigo lasting several days, without hearing impairment or neurological signs, with anterior and lateral semicircular canal involvement on video-Head-Impulse-Test (vHIT). A senior radiologist analyzed superior vestibular nerve and inner ear structure enhancement on cerebellopontine MRI.

RESULTS: One hundred and eighteen cases of SVN were included from May 2016 to February 2020. Statistical analyses concerned 106 cases. The SVN population had significantly less hypercholesterolemia (RR=0.40) than the general French population. There was no significant difference concerning other CVRFs. Superior vestibular nerve enhancement was observed on 84% of MRIs.

CONCLUSION: Prevalence of CVRF was not higher in patients with SVN than in the general population. The present study highlighted involvement of the superior vestibular nerve more than of the anterior vestibular artery in SVN.

Anterolateral advancement palatoplasty with tonsillectomy for retropalatal obstruction in selected cases of obstructive sleep apnea

xlomafota13 shared this article with you from Inoreader

Eur Arch Otorhinolaryngol. 2022 Jan 31. doi: 10.1007/s00405-021-07235-0. Online ahead of print.

ABSTRACT

PURPOSE: This study tried to assess the surgical outcome of anterolateral advancement palatoplasty (ALP) with simultaneous tonsillectomy for the treatment of retropalatal obstruction in selected cases of obstructive sleep apnea (OSA).

METHODS: In this clinical trial, 22 adult OSA patients having predominant retropalatal collapse were managed by ALP and tonsillectomy.Thirteen patients had positional OSA (PP) and 9 patients had non-positional (NPP). ALP entailed the stripping of a horizontal trapezoid area of mucosa/submucosa of the soft palate and suturing with one central simple suture and two paramedian sutures made as an anterolateral parallelogram. Uvula was not jeopardized and no lateral mucosal cuts were made.

RESULTS: Postoperative data of the study group showed high significant improvement (p < 0.001) as regard s apnea-hypopnea index (AHI), mean lowest oxygen saturation level (LO2), Epworth sleepiness scale (ESS) and snoring visual analog scale (VAS-s). The overall percentage of improvement as regards the AHI was 60%.On comparison of postoperative data of PP and NPP, significant difference was reported as regards AHI (p = 0.009), while non-significant differences were reported (p > 0.05) as regards LO2, ESS and VAS-s. Postoperative means of AHI in supine position showed a significant difference (p = 0.03). Upon comparison of means of ODI and T90% of PP and NPP, a highly significant difference was reported in both pre- and postoperative comparison (< 0.001).

CONCLUSION: Anterolateral advancement palatoplasty seems to be an easy, effective and low-cost procedure. More favorable outcomes were reported among positional-dependent subjects. The procedure could be employed in multilevel, single-stage surgery for patients with OSA.

Management of neurotoxicity following CAR-T cell therapy: Recommendations of the Francophone Society of Bone Marrow Transplantation and Cellular Therapy (SFGM-TC)

xlomafota13 shared this article with you from Inoreader

Bull Cancer. 2022 Jan 27:S0007-4551(22)00013-3. doi: 10.1016/j.bulcan.2021.12.013. Online ahead of print.

ABSTRACT

The immune effector cell-associated syndrome (ICANS) has been described as the second most frequent specific complication following CAR-T cell therapy. The median time to the onset of neurological symptoms is five days after CAR-T infusion. ICANS can be concomitant to cytokine release syndrome but often follows the resolution of the latter. However, 10 % of patients experience delayed onset after 3 weeks of CAR-T cell infusion. The duration of symptoms is usually short, around five days if an early appropriate treatment is given. Symptoms are heterogeneous, ranging from mild symptoms quickly reversible (alterations of consciousness, deterioration in handwriting) to more serious forms with seizures or even a coma. The ICANS severity is currently based on the ASTCT score. The diagnosis of ICANS is clinical but EEG, MRI and l umbar punction can help ruling out alternative diagnoses. The first line treatment consists of high-dose corticosteroids. During the twelfth edition of practice harmonization workshops of the Francophone Society of Bone Marrow Transplantation and Cellular Therapy (SFGM-TC), a working group focused its work on updating the SFGM-TC recommendations on the management of ICANS. In this review we discuss the management of ICANS and other neurological toxicities in patients undergoing of CAR-T cell therapy. These recommendations apply to commercial CAR-T cells, in order to guide strategies for the management neurological complications associated with this new therapeutic approach.

Objective Super-high and ultra-high spatial resolution computed tomography (CT) imaging can be advantageous for detecting temporal bone pathology and guiding treatment strategies. Methods Six temporal bone cadaveric specimens were used to evaluate the temporal bone microanatomic structures utilizing the following CT reconstruction modes: normal resolution (NR, 0.5-mm slice thickness, 5122 matrix), high resolution (HR, 0.5-mm slice thickness, 1,0242 matrix), super-high resolution (SHR, 0.25-mm slice thickness, 1,0242 matrix), and ultra-high resolution (UHR, 0.25-mm slice thickness, 2,0482 matrix). Noise and signal-to-noise ratio (SNR) for bone and air were measured at each reconstruction mode. Two observers assessed visualization of seven small anatomic structures using a 4-point scale at each reconstruction mode. Results Noise was significantly higher and SNR significantly lower with increases in spatial resolution (NR, HR, and SHR). There was no statistical difference between SHR and UHR imaging with regard to noise and SNR. There was significantly improved visibility of all temporal bone osseous structures of interest with SHR and UHR imaging relative to NR imaging (p < 0.001) and most of the temporal bone osseous structures relative to HR imaging. There was no statistical difference in the subjective image quality between SHR and UHR imaging of the temporal bone (p ≥ 0.085). Conclusion Super-high-resolution and ultra-high-resolution CT imaging results in significant improvement in image quality compared with normal-resolution and high-resolution CT imaging of the temporal bone. This preliminary study also demonstrates equivalency between super-high and ultra-high spatial resolution temporal bone CT imaging protocols for clinical use.
