ABSTRACT

BACKGROUND: Myelomeningocele is associated with hydrocephalus in 35% to 90% of cases. Hydrocephalus is usually treated with insertion of ventriculoperitoneal shunt; however, there is growing evidence that endoscopic third ventriculostomy (ETV) with choroid plexus cauterization (CPC) is an alternative.

OBJECTIVE: To compare the success rate and morbidity of ETV with CPC and ventriculoperitoneal shunt (VPS) as the primary treatment of hydrocephalus in patients with myelomeningocele.

METHODS: A prospective study from January 2016 to February 2019, involving 46 patients with myelomeningocele who developed hydrocephalus after repair in a tertiary hospital in southwestern Nigeria. Biodata and preoperative features of hydrocephalus were documented. ETV + CPC or VPS was done using standard operative techniques. Patients were followe d up monthly for 6 mo.

RESULTS: There were 23 patients in the ETV + CPC arm and 22 patients in the VPS arm. Morbidities were cerebrospinal fluid leak, 8.3% in the ETV + CPC arm and 4.5% in the VPS arm, wound dehiscence, 13.6% in the VPS arm, none in the ETV + CPC arm. At 6-mo follow-up, success rate for ETV + CPC was 60.9% and 59.1% for VPS, P = .9.

CONCLUSION: ETV + CPC had similar success rate with VPS at 6 mo with lower morbidity. ETV + CPC should be considered a viable alternative when treating patients with myelomeningocele and hydrocephalus.

A novel loop neurorrhaphy technique to preserve lower lip sensate in mandibular reconstruction using an innervated vascularized iliac bone flap

xlomafota13 shared this article with you from Inoreader

Abstract

Background

This study aimed to introduce a novel loop neurorrhaphy technique using an innervated vascularized iliac bone flap (VIBF) with vascularized ilioinguinal nerve (IIN) to reconstruct the inferior alveolar nerve (IAN) and preserve lower lip sensation simultaneously with mandibular reconstruction.

Methods

This study prospectively included patients who underwent mandibular reconstruction using VIBF from May 2018 to April 2020. Subjects were allocated into two groups: (1) Group I; innervated VIBF with loop neurorrhaphy (IIN doubly anastomosed with IAN and mental nerve), (2) Group II (control); conventional VIBF. Evaluation was done with operative time, intraoperative indocyanine green (ICG), lower lip sensory assessment (two-point discrimination [TPD] test and current perception threshold [CPT]), and drooling.

Results

Twelve patients were included; 6 in each group, (7 males and 5 females), age ranging from 18 to 57 years (average: 36.75 years). In all cases, intraoperative perfusion of IIN was confirmed by ICG. Group I showed a statistically significant more flap harvesting time compared with group II (mean difference, 5.67 min; P = 0.0091). There was a significant difference in sensory recovery favoring group I (P < 0.05). The TPD results in group I showed an average of 9.8 ± 6.9 mm and 6.2 ± 5.7 mm on operated and non-operated sides, while Group II showed a poor sensory recovery, and the TPD showed an average of 24.6 ± 6.7 mm and 8.4 ± 2.3 mm on operated and non-operated sides. The CPT results showed a significant difference between both groups. In Group I, the extent of drooling was 3.16 ± 0.75, while in Group II, the score was 1.6 ± 0.81, revealing a significant difference favoring Group I.

Conclusions

Concurrent mandibular reconstruction using VIBF and loop neurorrhaphy with vascularized IIN to reconstruct IAN successfully restore lower jaw form and preserve lip sensation.

xlomafota13 shared this article with you from Inoreader

Abstract

Background

Senhance is novel robotic platform which can be used to perform radical prostatectomy. We compare our results of robotic radical prostatectomy to similar patients operated with laparoscopic technique.

Results

There was no difference in the operative time, estimated blood loss, positive surgical margins, length of hospitalization, and catheterization. There were 4 (6.5%) Clavien-Dindo grade I complications, and 5 (8.1%) late complications in laparoscopy. There were 6 (5.6%) Clavien-Dindo grade I, 3 (2.8%) grade II, 1 (0.9%) grade IV complications, and 2 (1.9%) late complications in robotic group.

Conclusion

Senhance robot-assisted radical prostatectomy is safe, feasible and offers good and comparable functional and oncological outcomes to laparoscopy. The transition to robotic surgery with a relatively fast learning curve can be done effectively for surgeons with previous laparoscopic experience.

Long‐term outcomes of Aminolevulinic Acid Photodynamic Therapy for Treatment of Recalcitrant Laryngeal Premalignant Lesions

xlomafota13 shared this article with you from Inoreader

Abstract

Objective

Assess long-term outcomes of ALA-PDT in treating recalcitrant laryngeal leukoplakia.

Study design

Retrospective Case-Control.

Methods

We reviewed all laryngeal leukoplakia patients treated with ALA-PDT compared with angiolytic laser treatment alone (585nm PDL or 532nm KTP laser) from 2000 to 2019. Patients with laryngeal cancer (or a history of laryngeal cancer), leukoplakia previously treated with radiation and no pathologic report were excluded. Patient demographics, procedure details, and outcomes were examined including histopathologic diagnosis, procedures performed, ALA usage, recurrence of leukoplakia, and the development of cancer.

Results

We identified 132 patients with laryngeal leukoplakia: 42 were treated with ALA-PDT and 90 were treated with an angiolytic laser alone (Laser group). The proportion of cases of high-grade dysplasia was 57.1% in the ALA-PDT group compared to 32.2% in the Laser group. In high-grade dysplasia cases, there was a statistically significant better recurrence-free survival (RFS) at 12 months and 60 months in those who underwent ALA-PDT 71.4% and 7.1% vs Laser 25% and 0% (P=0.01). However, for overall group there was no difference in RFS (P=0.25). Voice outcomes (Patient subjective report) improved or were stable in 75% of subjects with no serious side effects reported.

Conclusion

ALA-PDT for recalcitrant and high-grade dysplasia is highly effective with improved recurrence-free survival compared to laser alone. ALA-PDT may be an appropriate therapy in patients who have failed prior angiolytic laser alone.

Concurrent Chemoradiotherapy with Cisplatin and Docetaxel for Head and Neck Squamous Cell Carcinoma

xlomafota13 shared this article with you from Inoreader

Abstract

Objectives

Concurrent chemoradiotherapy (CCRT) with high-dose cisplatin is considered as the global standard therapy to treat patients with advanced head and neck cancer (HNSCC). High doses of cisplatin (100mg/m2) induce severe adverse effects that hinder the completion of therapy, and late toxicity, including renal dysfunction, may prevent patients from receiving treatment with second-line chemotherapies.

Design

We retrospectively analyzed the effect of CCRT combined with moderate-dose cisplatin (4x15 mg/m2) and docetaxel (50 mg/m2) in 83 patients with locally advanced HNSCC.

Results

The median follow-up period was 31 months (range 3-100 months). Radiotherapy was completed in 98% of patients including 36 patients (43%) aged 70 or older. The overall complete response rate was 87% with preserving renal function. The 3-year overall survival, disease-specific survival and progression-free survival rates were 71%, 81% and 70%, respectively. The 3-year disease-specific survival with organ preservation was 79%.

Conclusion

CCRT with a combination of moderate-dose cisplatin and docetaxel in HNSCC patients was well tolerated; it also demonstrated comparable clinical responses to CCRT using high-dose cisplatin

The prevalence of CFTR mutations in patients with chronic rhinosinusitis: A systematic review and meta‐analysis.

xlomafota13 shared this article with you from Inoreader

Abstract

Objectives

Undetected cystic fibrosis transmembrane regulator (CFTR) mutations may predispose individuals to develop CRS independent of formal CF diagnosis. The objective of this study was to determine the prevalence of CFTR mutations among individuals with CRS.

Design

A systematic search following PRISMA guidelines was performed. A meta-analysis was performed to calculate pooled estimates for the prevalence of any CFTR mutation and for the DF508 mutation.

Setting and participants

The systematic search included all studies identifying adults diagnosed with CRS, with no limitation to region or publication date. Studies had to identify a sample of patients previously diagnosed with CRS but not with CF and reporting testing for the prevalence of CF or the CFTR gene mutation

Main outcome measures

Prevalence of CFTR mutations among the general CRS population, with subgroup analysis of individuals with the dF508 mutation.

Results and conclusions

The 6 included studies represented five countries: the US, the UK, France, Poland, and Finland. The pooled prevalence of CFTR mutations of any kind in CRS subjects without CF was 5.65% (RE 95% CI 2.99 – 10.41). The overall prevalence for the dF508 mutation was 4.22% (RE 95% CI 1.71 – 10.07). These estimates were significantly higher than the baseline estimated prevalence of CFTR carrier status of 3-4% in the general population.

However, the clinical relevance of the presence of CFTR mutations in CRS patients who have not been diagnosed with CF is currently unclear. Future studies should include sweat chloride testing as a measure of CFTR function.

Nat Commun. 2021 Oct 18;12(1):6058. doi: 10.1038/s41467-021-26343-3.

ABSTRACT

The tumor ecosystem of papillary thyroid carcinoma (PTC) is poorly characterized. Using single-cell RNA sequencing, we profile transcriptomes of 158,577 cells from 11 patients' paratumors, localized/advanced tumors, initially-treated/recurrent lymph nodes and radioactive iodine (RAI)-refractory distant metastases, covering comprehensive clinical courses of PTC. Our data identifies a "cancer-primed" premali gnant thyrocyte population with normal morphology but altered transcriptomes. Along the developmental trajectory, we also discover three phenotypes of malignant thyrocytes (follicular-like, partial-epithelial-mesenchymal-transition-like, dedifferentiation-like), whose composition shapes bulk molecular subtypes, tumor characteristics and RAI responses. Furthermore, we uncover a distinct BRAF-like-B subtype with predominant dedifferentiation-like thyrocytes, enriched cancer-associated fibroblasts, worse prognosis and promising prospect of immunotherapy. Moreover, potential vascular-immune crosstalk in PTC provides theoretical basis for combined anti-angiogenic and immunotherapy. Together, our findings provide insight into the PTC ecosystem that suggests potential prognostic and therapeutic implications.

Ear Nose Throat J. 2021 Oct 18:1455613211051660. doi: 10.1177/01455613211051660. Online ahead of print.

ABSTRACT

Bacckground: Approximately 80% to 85% of sudden sensorineural hearing loss (SSNHL) is idiopathic, but immune-mediated mechanisms are thought to be involved. Behçet disease is an autoinflammatory vasculitis that may involve vessels of the inner ear. It can cause sensorineural hearing loss (SNHL) and an increased risk of SSNHL. Study Sample: We report a 21-year-old man who was diagnosed with Behçet disease in childhood and presented to our clinic with a 10-day history of abrupt hearing deterioration in both ears. Pure-tone audiometry showed severe to profound bilateral SNHL. Results: Oral prednisolone was prescribed for 3 weeks. Concurrent intratympanic steroid injections (ITSIs) were administered in each ear every 2 days for 5 days. A total of 15 daily sessions of hyperbaric oxygen therapy (HBOT) were completed. Acupuncture was performed every 2 days for 1 month. After these combined therapies, the patient's hearing threshold by 20 dB and his speech recognition threshold were improved. Conclusions: Some patients with SSNHL recover no hearing improvement after routine treatment, and alternative treatments including ITSI, HBOT, and acupuncture can be considered as optional. We used an aggressive multimodal approach to treat severe bilateral SSNHL in patient with Behçet disease.

The Roles Played by Blood Inflammatory Parameters in Sudden Sensorineural Hearing Loss

xlomafota13 shared this article with you from Inoreader

pubmed-meta-image.png

Ear Nose Throat J. 2021 Oct 18:145561320960355. doi: 10.1177/0145561320960355. Online ahead of print.

ABSTRACT

OBJECTIVE: The etiology of sudden sensorineural hearing loss (SSNHL) remains unknown; inflammation may be one cause. We retrospectively studied SSHNL cases in terms of the inflammatory parameters involved.

METHODS: We reviewed 169 SSNHL cases. The control group contained 132 patients with vocal cord polyps. The C-reactive protein (CRP) level, CRP/serum albumin (Alb) ratio, and neutrophil/lymphocyte ratio (NLR) were compared between the 2 groups. The relationships between these parameters and the time to treatment after SSHNL onset, hearing level, and therapeutic effects were also analyzed.

RESULTS: The CRP level, CRP/Alb ratio, and NLR were higher in SSNHL patients than in controls, but only the NLR differed significantly between the 2 groups. We found no significant differences between patients with different hearing levels, those evaluated at various times after SSNHL onset, and those with different outcomes.

CONCLUSION: The NLR is a reliable SSNHL diagnostic marker. The CRP level and CRP/Alb ratio are not useful indicators.

Low skeletal muscle mass assessed directly from the 3rd cervical vertebra can predict pharyngocutaneous fistula risk after total laryngectomy in the male population

xlomafota13 shared this article with you from Inoreader

Eur Arch Otorhinolaryngol. 2021 Oct 19. doi: 10.1007/s00405-021-07127-3. Online ahead of print.

ABSTRACT

PURPOSE: Skeletal muscle mass (SMM) loss and sarcopenia have been identified as risk factors for postoperative complications. The aim of this study was to investigate the relationship between pharyngocutaneous fistula (PCF) formation after total laryngectomy (TL) and SMM assessed from a computed tomography image of the 3rd cervical vertebra (C3).

METHODS: Retrospective study of 86 male patients who underwent TL between 2013 and 2019 in a single institution. We excluded women from the analysis due to our limited sample. SMM was determined from cross-sectional muscle area (CSMA) measurement at C3 using the ImageJ software. Results were compared with those for the skeletal muscle mass index (SMMI) calculated from the estimated measure at 3rd lumbar vertebra (L3).

RESULTS: PCF formation occurred in 21/86 patients. According to the CSMA at a C3 cut-off of 35.5cm2, of 18 patients (20.9%) with low SMM, 9 developed PCFs (50.0%). Among patients with normal SMM (n = 68, 79.1%), 12 developed PCFs (17.6%). The CSMA at C3 was the only variable significantly associated with PCF risk, which was 4.7 times greater in patients with low SMM (p = 0.007). Sarcopenia was more frequent in underweight patients (p = 0.0001), patients undergoing extended surgeries (p = 0.003), or presenting preoperative anaemia (p = 0.009) or hypoalbuminemia (p = 0.027).

CONCLUSION: Measuring the CSMA at C3 obtained results equivalent to those obtained by calculating the SMMI at L3, suggesting that direct SMM assessment from C3 is a useful approach to evaluating PCF formation risk after TL.

Valproic acid during pregnancy decrease the number of spermatogenic cells and testicular volume in the offspring of mice: Stereological quantification

xlomafota13 shared this article with you from Inoreader

Histol Histopathol. 2021 Oct 19:18380. doi: 10.14670/HH-18-380. Online ahead of print.

ABSTRACT

Valproic acid (VPA) is a drug used to treat epilepsy, bipolar disorders and headaches. As a secondary effect, this antiepileptic drug can cause a decrease in androgens and gonadotropins, and dose-dependent testicular defects, such as reduction of testicular weights, sperm motility and degeneration of the seminiferous tubules. In offspring exposed to VPA, its effects have not been evaluated, so the study aimed to determine the morphological effects of the use of VPA along testicular development in mice. 30 adult female BALB/c mice were crossed and divided by age, with embryos of 12.5 days post coitum (dpc), fetuses of 17.5 dpc and male mice 6 weeks postnatal. In each case, the pregnant mouse received 600 mg/kg of VPA, making up the VPA groups, or 0.3 mL of 0.9% physiological solution for the control groups, from the beginning to the end of th e pregnancy, orally.t. A morpho-quantitative analysis was carried out on the gonadal development of the male offspring. In the groups treated with VPA, at all ages studied they had lower testicular volume. At 12.5 dpc, they showed less testicular development in the form of sex cords, with fewer gonocytes and somatic cells. At 17.5 dpc, they presented greater interstitial space, fewer spermatogonial, sustentacular Sertoli, peritubular and interstitial Leydig cells. At 6 weeks postnatal, they presented fewer spermatogonia, pachytene spermatocytes, elongated spermatids, sustentacular Sertoli and interstitial Leydig cells, with statistically significant differences. In conclusion, prenatal exposure to VPA causes histopathological alterations in the offspring of mice in testicular development, from the embryonic stage to 6 weeks postnatal.
