Predictive value of esophageal motility test in the proficiency of esophageal speech

One method of speech rehabilitation following total laryngectomy surgery is esophageal speech therapy (EST). In this method, which has witnessed relatively low success rates at the end of therapy, identification of patients who can benefit from EST beforehand will be important for determining the appropriate method for alaryngeal speech rehabilitation and might be cost‐effective, saving time and labor. To this end, this study conducted research on the feasibility of manometric data measured prior to therapy using an esophageal motility test (EMT) in order to determine the candidates most suitable for esophageal speech (ES) beforehand. A total of 51 total laryngectomy male patients who had never been subject to any kind of speech rehabilitation and had always been articulate were included in the study. Data were collected from 44 patients who completed EST, lasting for 6 months in total and consisting of 11 sessions. Manometric measures were obtained through EMT using a water‐perfusion system with a Dent sleeve catheter on the patients prior to the therapy. Wepman's scale was used in order to evaluate ES proficiency. Following the therapy, in accordance with this scale, while patients whose scores was 1, 2, or 3 were considered as adequate, those whose scores were 4, 5, 6, or 7 were considered inadequate and were divided into two groups. Manometric correlations were analyzed between 17 patients (group I) who were able to perform ES at an adequate level and 27 patients (group II) who could not. No statistically significant difference between the groups could be observed in terms of average pressure generated within the upper and lower esophageal sphincters obtained through EMT, peak amplitude of esophageal body contraction pressure, contraction duration time, onset velocity, or peak velocity values. EMT conducted prior to application of EST to total laryngectomized patients did not have any value in determining the level of ES that a patient could reach. Our results also suggest that sphincter pressures or esophageal motility patterns do not have any predictive value and should not be performed.     

Cardiovascular health-related quality of life in cancer: a prospective study comparing the ESC HeartQoL and EORTC QLQ-C30 questionnaire

Aims

Health-related quality of life (HRQoL) is highly relevant in cancer and often assessed with the EORTC QLQ-C30. Cardiovascular HRQoL in cancer can be measured with the ESC HeartQoL questionnaire. We compared these instruments and examined their prognostic value.

Methods and results

Summary scores for EORTC QLQ-C30 (0–100 points) and ESC HeartQoL (0–3 points) questionnaires were prospectively assessed in 290 patients with mostly advanced cancer (stage 3/4: 81%, 1-year mortality: 36%) and 50 healthy controls (similar age and sex). Additionally, physical function and activity assessments were performed. Both questionnaires demonstrated reduced HRQoL in patients with cancer versus controls (EORTC QLQ-C30: 67 ± 20 vs. 91 ± 11, p < 0.001; ESC HeartQoL: 1.8 ± 0.8 vs. 2.7 ± 0.4, p < 0.001). The instruments were strongly correlated with each other (summary scores [r = 0.76], physical [r = 0.81], and emotional subscales [r = 0.75, all p < 0.001]) and independently associated with all-cause mortality (best cut-offs: EORTC QLQ-C30 <82.69: hazard ratio [HR] 2.33, p = 0.004; ESC HeartQoL <1.50: HR 1.85, p = 0.004 – adjusted for sex, age, left ventricular ejection fraction, N-terminal pro-B-type natriuretic peptide [NT-proBNP], high-sensitivity troponin T, cancer stage/type), with no differences in the strength of the association by sex (p-interaction > 0.9). Combining both questionnaires identified three risk groups with highest mortality in patients below both cut-offs (vs. patients above both cut-offs: HR 3.60, p < 0.001). Patients with results below both cut-offs, showed higher NT-proBNP and reduced physical function and activity.

Conclusions

The EORTC QLQ-C30 and ESC HeartQoL – assessing cancer and cardiovascular HRQoL – are both associated with increased mortality in cancer patients, with even greater stratification by combing both. Reduced HRQoL scores were associated with elevated cardiovascular biomarkers and decreased functional status.     

Biliary complications after right lobe living donor liver transplantation: a single-centre experience

Background

Biliary complications that developed after right lobe liver transplantation from living donors were studied in a single centre.

Methods

From 2004 to 2010, 200 consecutive living donor right lobe liver transplantations were performed. The database was evaluated retrospectively. Biliary complications were diagnosed according to clinical, biochemical and radiological tests. The number of biliary ducts in the transplanted graft, the surgical techniques used for anastomosis, biliary strictures and bile leakage rates were analysed.

Results

Of a total of 200 grafts, 117 invloved a single bile duct, 77 had two bile ducts and in six grafts there were three bile ducts. In 166 transplants, the anastomosis was performed as a single duct to duct, in 21 transplants double duct to ducts, in one transplant, three duct to ducts and in 12 transplants as a Roux-en-Y reconstruction. In all, 40 bile leakages (20%) and 17 biliary strictures (8.5%) were observed in 49 patients resulting in a total of 57 biliary complications (28.5%). Seventeen patients were re-operated (12 as a result of bile leakages and five owing to biliary strictures).

Conclusion

Identification of more than one biliary orifice in the graft resulted in an increase in the complication rates. In grafts containing multiple orifices, performing multiple duct-to-duct (DD) or Roux-en-Y anastomoses led to a lower number of complications.     

Melatonin levels in premenopausal women with fibromyalgia syndrome

The fibromyalgia syndrome (FMS) is a chronic, widespread pain disorder of unknown etiology. It has been suggest that familial component, environmental factors, endocrine and neurotransmitter alterations, and psychological factors may contribute to the development of FMS. The role of melatonin in FMS is unclear. Some studies describe a lower nocturnal peak and a decreased secretion of melatonin in women with FMS when compared with healthy matched controls. The aim of the present study was to determine the possible role of melatonin in FMS patients. We examined the characteristics and levels of melatonin in 25 consecutive premenopausal women with FMS. Serum blood samples were collected from 25 patients and 20 the age and gender matched healthy controls. Melatonin levels were measured by enzyme-linked immunosorbent assay. Then, the results were compared with those from healthy subjects. Serum melatonin levels of FMS patients were not statistically different from those of controls (P > 0.05). No association was observed between melatonin levels of patients with FMS and disease duration, sleep disturbances, fatigue, and pain scores. Our results demonstrate that melatonin levels were similar in patients with FMS and healthy controls. Further studies are needed to determine the possible role of melatonin.     

The accuracy of frozen section (intraoperative consultation) in the diagnosis of ovarian masses

OBJECTIVE: Frozen section is an important and helpful adjunct in the intraoperative diagnosis of ovarian tumors. This retrospective study was undertaken to determine the accuracy of frozen section diagnosis of ovarian masses and the reasons of discordance. METHODS: From January 1995 to December 2003, 1494 ovarian specimens were received for histopathological evaluation, and 617 of them were submitted for frozen section examination. RESULTS.: The final paraffin section diagnoses of these 617 cases were a nonneoplastic lesion in 18.3% of the cases, benign tumor in 56.1%, borderline tumor in 6.2%, and malignant tumor in 19.4%. The overall accuracy was 97%. Twenty-one cases were incorrectly diagnosed by frozen section. All of them were false negatives. There were no deferred cases. The majority of the cases of disagreement were mucinous and borderline tumors. The sensitivity for benign, borderline, and malignant tumors were 100%, 87%, and 87%, respectively. The specificity for benign tumors was 97%; for borderline tumors 98%; and for malignant tumors 100%. CONCLUSION: Our data confirm that frozen section diagnosis is a reliable method for the surgical management of patients with an ovarian mass. However, diagnostic problems can occur in mucinous and borderline tumors during frozen section examination. The clinicians and pathologists must be aware of the pitfalls of this method; therefore, a good communication established between them is necessary to obtain more accurate results and to minimize the number of deferred cases.     

Differential Expression of Hypertension-Associated MicroRNAs in the Plasma of Patients With White Coat Hypertension

White coat hypertension (WCH) is a high cardiovascular risk condition, and a fundamental understanding of the cause and pathophysiology of the disorder is still lacking. Recent studies demonstrated that microRNAs (miRNAs) are involved in hypertension; however, the roles of miRNAs in WCH are not known.The expressions of selected 10 miRNAs were investigated independently in plasma samples from 30 hypertension (HT) patients, 30 WCH patients, and 30 normotensive (NT) subjects.MiR-21, miR-122, miR-637, and let-7e expression levels were significantly upregulated in the HT group compared with the NT groups (P = 0.017, P = 0.022, P = 0.048, and P = 0.013, respectively). MiR-122 and miR-637 expressions were also significantly upregulated in the WCH group compared with the NT group (P = 0.048 and P = 0.039, respectively). MiR-296-5p expression level was significantly downregulated in HT patients and upregulated in the WCH patients compared with the NT group (P = 0.049 and P = 0.039, respectively).Additionally, the ambulatory 24-hour and daytime systolic and diastolic blood pressures were negatively correlated with miR-296-5p. MiR-296 and miR-637 had area under the curve (AUC) values of 0.778 and 0.774, respectively, which demonstrates their sufficiency to distinguish WCH from NT individuals. MiR-296 and miR-637 had AUC values of 0.868 and 0.680, respectively, which shows their potential to distinguish WCH from HT individuals.We report for the first time a plasma miRNA profile for WCH patients and demonstrate a novel link between miRNA and WCH. These findings may reveal crucial insights into the development of WCH.
