Validation and Cross-Cultural Adaptation of Croatian Self-Evaluation of Communication Experiences after Laryngectomy Questionnaire.

INTRODUCTION: The Self-Evaluation of Communication Experiences after Laryngectomy (SECEL) is a 35-item patient-reported questionnaire developed to address the communication needs of patients with laryngectomies. The aim was to translate, cross-culturally adapt, and validate the Croatian version. METHODS: The SECEL was translated from English by two independent translators and back-translated by a native speaker, after which it was approved by an expert committee. The Croatian version of the Self-Evaluation of Communication Experiences after Laryngectomy questionnaire (SECEL:HR) was filled in by 50 laryngectomised patients who had completed their oncological treatment a year prior to inclusion in the study. Patients also filled in the Voice Handicap Index (VHI) and the Short Form Health Survey (SF-36) on the same day. All patients completed the SECEL:HR twice, the second time being 2 weeks after the initial test. Maximum phonation time and diadochokinesis of articulation organs were used for objective assessment. RESULTS: Among the Croatian patients, the questionnaire was well-accepted and demonstrated good test-retest reliability and internal consistency for two out of three subscales. The correlations between VHI, SF-36, and SECEL:HR were moderate to strong. There were no significant differences between patients who are using oesophageal speech, tracheoesophageal speech, or the electrolarynx based on the SECEL:HR. CONCLUSION: Preliminary findings of the research indicate that the Croatian version of the SECEL has sufficient psychometric qualities, high reliability, and good internal consistency, with a Cronbach's alpha of 0.89 for the total score. The Croatian version of SECEL can be recommended as a reliable and clinically valid measure for the assessment of substitution voices in Croatian-speaking patients.

Prognostic Significance of BRAF V600E Mutation and CPSF2 Protein Expression in Papillary Thyroid Cancer.

The early-stage diagnosis of papillary thyroid cancer (PTC) has significantly increased in incidence worldwide without any beneficial impact on survival. In order to improve the risk assessment in PTC, we have conducted a retrospective study in which we analyzed the BRAF V600E mutation and CPSF2 protein expression as prognostic markers on archival tissue samples of 49 patients without (control group) and 97 patients with (study group) PTC metastases in the cervical lymph nodes at the time of initial diagnosis. Our aim was to correlate the BRAF V600E mutation and the expression of CPSF2 protein with the clinical and pathological features of PTC. The expression of CPSF2 protein was evaluated via immunohistochemistry and graded semi-quantitatively. The presence of the BRAF V600E mutation was determined via real-time polymerase chain reac-tion (PCR). CPSF2 protein < 3+ intensity expression was correlated with more frequent recurrences (Fisher-Freeman-Halton exact test; p = 0.010; 95% CI: 1.26−22.03), and patients who presented with the BRAF V600E mutation and CPSF2 protein expression < 3+ intensity had shorter disease-free survival (log-rank test; 105.0 months vs. 146.6 months; p < 0.001; HR 8.32, 95% CI: 2.91−23.83), whereas patients with PTC who had CPSF2 expression 3+ had longer disease-free survival in correlation with other lower intensity expressions of CPSF2 protein (log-rank test; 139.7 months vs. 129.6 months; p = 0.008). The multivariate analysis showed that younger patients with CPSF2 protein expression <3+ and the BRAF V600E mutation are at an increased risk for recurrence and require more intensive monitoring (Cox proportional hazards regression model; X2 = 17.5, df = 10, p = 0.025). Our results correlate the BRAF V600E mutation and CPSF2 protein expression with recurrence and disease-free survival as relevant prognostic factors for PTC.

Influence of proton pump inhibitor therapy on occurrence of voice prosthesis complications.

PURPOSE: It has been shown that the reflux of the gastric content to the proximal oesophagus influences incidence of voice prosthesis (VP) complications in laryngectomized patients. We conducted prospective randomised study to investigate the relationship between pepsin concentration in saliva and occurrence of VP complications before and after 3 months of proton pump inhibitor (PPI) therapy. METHODS: 60 laryngectomized patients with VP and 30 controls were included in the study. Saliva samples were collected in the morning and concentration of pepsin were measured by Human Pepsin (PG) ELISA kit. Thirty-Four (57%) patients reported one or more VP complication and were randomised in two groups, with and without PPI therapy, 40 mg pantoprazole per day for 3 months. RESULTS: Patients who had longer time since last VP change had higher incidence of periprosthetic and transprosthetic leakage and Candida colonisation. Pepsin was found in all saliva samples. Median saliva pepsin concentration level did not significantly differ between laryngectomized patients and control subjects, or between patients with and without VP complications, and there was no correlation between saliva pepsin concentration levels and type of VP complication. After 3 months therapy, there was no difference in median saliva pepsin level or incidence of VP complication between patients with and without PPI therapy. CONCLUSION: Although reflux was proposed to be associated with VP complications and pepsin was proven as a most sensitive and specific marker of EER, we did not find any statistically significant correlation between pepsin levels and occurrence of VP complications. A 3 months 40 mg pantoprazole therapy was ineffective in reduction of VP complications in our study group.

Autologous Fat Augmentation in the Treatment of Unilateral Vocal Fold Paralysis - A 15-year Experience in a Single Institution.

Autologous fat vocal fold augmentation is a widespread surgical procedure that aims to repair glottal incompetence in patients with unilateral vocal fold paralysis (UVFP). However, there are some concerns in the literature about the long-term results of this technique. At the ENT Department of the Zagreb University Hospital Centre, this technique has been in use for more than 15 years, and a retrospective medical chart review was conducted from June 2005 to November 2019. Overall, 78 patients with UVFP met the inclusion criteria for enrolment in the study. All patients underwent at least one preoperative and two postoperative voice assessments, one early (within 3 months from surgery) and one late (at least 1 year after surgery). All tested voice outcome parameters (maximum phonation time (MPT), jitter, shimmer, noise-to-harmonic ratio (NHR)) significantly improved after surgery, both early and late postoperatively (p<0.001). The reoperation rate was only 10.3% (8/78), with the majority of patients in our series experiencing long-term benefits from this surgical procedure. According to the results of our study, autologous fat vocal fold augmentation appears to be a highly useful and effective surgical technique with long-lasting results in the majority of patients suffering from UVFP.

Thyroidectomy-related Swallowing Difficulties: Review of the Literature.

This study aims to provide insight into the etiology and frequency of swallowing complications that arise after thyroidectomy and to outline the available diagnostic procedures by revising the existing literature on this topic. We conducted a bibliographic search using the electronic database MEDLINE/PubMed to identify all relevant articles and 44 studies were included in the review out of a total of 218 published articles. Dysphagia after thyroid surgery is a common postoperative complication which, in the short- or long-term, significantly affects patient life quality. There is no standard diagnostic protocol for thyroidectomy-related swallowing impairment. Among the reviewed studies, 8 questionnaires and 12 instrumental diagnostic tools were used to identify swallowing difficulties related to thyroid surgery. The Swallowing Impairment Index (SIS-6) was the most-used questionnaire. Fiberoptic endoscopy is a standard diagnostic tool performed prior and after thyroid surgery, primarily to identify changes in vocal fold mobility. Although instrumental findings usually reveal non-specific alterations of swallowing; swallowing videofluoroscopy and esophageal manometry can be the most helpful tools in further management of thyroidectomy dysphagia. In patients with thyroidectomy-related swallowing difficulties and suspected laryngopharyngeal reflux, 24-hour MII-pH metry should be performed.

METABOLIC ACIDOSIS--AN UNDERESTIMATED PROBLEM AFTER KIDNEY TRANSPLANTATION?.

Despite prolonged survival and better quality of life as compared to dialysis, kidney transplantation frequently presents with a complex set of medical issues that require intensive management to protect graft function. Metabolic acidosis has an impact on several metabolic complications such as mineral and muscle metabolism, nutritional status and anemia. It may also have an effect on graft function, possibly through the stimulation of adaptive mechanisms aimed at maintaining acid-base homeostasis. We investigated current practice in the evaluation of metabolic acidosis at one of the largest transplant centers in the Eurotransplant region. Adult renal transplant recipients having received allograft from January 2011 to August 2012 were included in the investigation. We recorded the frequency of measuring the parameters of venous blood gas analysis, as well as creatinine and urea levels, creatinine clearance, proteinuria, calcium, phosphate and potassium blood levels, body mass index and the time spent on dialysis prior to kidney transplantation. Out of 203 patients who had received renal allograft at our institution during the observed period, 191 (124 males and 67 females, age range from 18 to 77 years) were enrolled in the study. Of these, only 92 (48.167%) patients had parameters of venous blood gas analysis measured at some time after kidney transplantation. Acid-base status was determined more often in males (77 males vs. 22 females, p = 0.001). Patients with pH/blood gas analysis performed were found to have significantly higher creatinine and urea levels and significantly lower creatinine clearance (p < 0.001 both). Serum calcium levels were also significantly lower in this group of patients (p < 0.001). Metabolic acidosis is a very important clinical issue that needs to be monitored in every transplant recipient. Its effects on graft function, nutritional status, anemia and bone mass are complex but can be successfully managed. Our study showed metabolic acidosis to be linked with significantly higher creatinine and urea levels, decreased creatinine clearance and lower calcium levels. Nevertheless, metabolic acidosis still stays a highly underestimated problem among nephrologists dealing with transplant recipients. We suggest regular determination of the acid-base status in renal transplant recipients.

Necrotizing fasciitis of the neck after total laryngectomy.

Necrotizing fasciitis (NF) is an unusual, life threatening, rapidly advancing infection characterized by widespread fascial and subcutaneous tissue necrosis and gangrene of the skin. It most commonly affects the extremities, abdominal wall and perineum, whereas cervical NF is rare. NF of the head and neck is often caused by both aerobic and anaerobic microorganisms found in the upper aerodigestive tract. Usually, cervical NF originates from odontogenic, tonsillar and pharyngeal infection, and it is very rarely a complication of surgical procedure. Without immediate surgical treatment, cervical NF leads to mediastinitis and fatal sepsis. There is only one case of cervical NF after total laryngectomy described in the literature. We report two cases of cervical NF after total laryngectomy, selective neck dissection and primary vocal prosthesis insertion. In both cases, the infection spreads to thoracic region and in one of them NF was associated with Lemierre's syndrome, i.e., thrombosis of the internal jugular vein. In both patients, vocal prosthesis was inserted during the infection and did not influence the healing process.

The significance of Helicobacter pylori in patients with nasal polyposis.

AIM: To determine the presence of Helicobacter pylori in nasal polyps and the transmission of H. pylori from stomach to nasal polyps. METHODS: In a prospective, controlled clinical research, 35 subjects with nasal polyps and 30 controls with concha bullosa (CB) were involved, and had been subjected to endoscopic sinus surgery (ESS). In the biopsies of removed polyps and CB, polymerase chain reaction (PCR) was used for detecting the H. pylori DNA. Blood samples of the test and control group were evaluated for H. pylori immunoglobulin (Ig) G and A antibodies by ELISA. The test and control group underwent esophagogastroduodenoscopy with taking biopsies from the stomach for PCR detection of H. pylori DNA. RESULTS: In blood samples, specific IgG and IgA antibodies to H. pylori were found in 30 (85.71%) of 35 polyp patients and in 16 (53.33%) of 30 controls. In 10 (28.57%) of 35 patients H. pylori DNA was identified in the nasal polyp tissue, but it was not detected in the CB specimens. H. pylori DNA was found in the stomach mucosa samples of all test and control group of subjects. Significant statistical difference was found in the H.pylori specific IgG and IgA between the test and control group (p less 0.006) and between the polyp and control biopsy specimens of H. pylori DNA by PCR (p less 0.001). CONCLUSION: This research points to the colonisation of nasal polyps with H. pylori, the transfer of H. pylori from stomach to nasal polyps and potential role of H. pylori in emergence of nasal polyps.

[Laryngotracheal stenosis--etiology and therapeutic options]. / Laringotrahealne stenoze--etiologija i terapijske mogucnosti.

UNLABELLED: Laryngotracheal stenosis, although not very common, is an important medical condition that represents a true diagnostic and therapeutic challenge. We present our experiences in treating 22 patients with laryngotracheal stenosis between 1995 and 2004 at Department of ENT, Head and Neck Surgery, Dr. Josip Bencevic General Hospital in Slavonski Brod. PATIENTS AND METHODS: Stenosis was caused by trauma in 9 patients, by endotrauma due to intubation in 3, and by war penetrating injury caused by shell and mine fragments in 4 patients. Hypertrophic glottic stenosis, after supraglottic laryngectomy and postoperative radiotherapy caused laryngeal obstruction in 2 patients. Tumors caused stenosis in 11 patients: tumors of the thyroid with compression in 9, and malignant infiltration of the trachea in 2 patients. Glottic stenosis was present in 4, glottic and subglottic in 4, subglottic and tracheal in 2, isolated tracheal stenosis in 12 patients. Surgical treatment was performed in 14 patients: endoscopic in two and classic open procedure in 12 patients. Laryngeal and tracheal stents were inserted in 3 patients with inopeable thyroid tumor. All treated patients except one were extubated. RESULTS: Excellent functional results were achieved upon endoscopic resection, resection of stenosis and end-to-end anastomosis. Minimally invasive and good palliative treatment was achieved by the stent placement into the airway.
