[A case of successful plasma transurethral enucleationof benign prostatic hyperplasia the size of 530 cm3]

The article presents a description of the clinical case. Surgical treatment by plasma transurethral enucleation of the prostate was performed in patients with benign prostatic hyperplasia of giant size - 530 cm3. Observation in the short term showed the absence of functional and organic complications. Comparison with the results of surgical treatment of giant prostate adenoma by classical transurethral enucleation of the prostate, obtained in our urological clinic in 2015, showed a reduction in operating time by 1 hour without a significant increase in blood loss during surgery and without operational complications. The results demonstrate the prospects of the widespread introduction of plasma methods of transurethral operations in urological practice.

Assessment of Oral Function and Proper Diet Level for Frail Elderly Individuals in Nursing Homes Using Chewing Training Food

OBJECTIVES

We aimed to investigate the relationship between the ability to press Process Lead (PL) in the oral cavity and the tongue pressure and recommended diet form for elderly individuals in nursing homes, using PL normalized physical properties.

DESIGN

Cross-sectional observation study.

SETTING

Geriatric facilities.

PARTICIPANTS

A 100 elderly individuals aged between 67-96 years.

MEASUREMENTS

PL was pressed between the tongue and palate to evaluate its deformation. The thickness was set at 6, 9, and 18 mm. The tongue pressure was measured with a JMS tongue pressure manometer. The number of chewing cycles until an 18-mm thick PL was first swallowed was measured (PL chewing test). The diet was set to level 4, and the recommended form was evaluated by video endoscopic evaluation of swallowing (VE). The results of the PL pressing test and correlations between PL chewing test, tongue pressure, and diet level were statistically examined.

RESULTS

The tongue pressure was significantly decreased in groups that could not press the PL. The PL pressing test and recommended diet form showed a significant correlation, and the elderly with difficulty in pressing the PL had a lower diet level. In addition, the diet level decreased with decreased PL chewing test performance in those without molar occlusion.

CONCLUSIONS

The PL pressing and chewing tests may aid in ascertaining the appropriate diet level. In the future, we would like to verify the usefulness of these tests in determining the diet level of elderly people requiring long-term care at the time of entering the facility.

Patellofemoral reconstruction for patellar instability with patella alta in middle-aged patients: Clinical outcomes

INTRODUCTION

Although several surgical treatments for patellar instability with patella alta have been reported, the clinical outcomes and optimal surgical procedures for patellar instability with patella alta in middle-aged patients are still controversial. We hypothesized that optimal surgical procedures for patellar instability with patella alta in middle-aged patients may induce good clinical outcomes with better patellofemoral geometry.

MATERIALS AND METHODS

Twelve middle-aged patients with a mean age of 44 years (range: 40-55 years), who presented with patellar instability and patella alta, were treated with a combination of several surgeries, such as medial patellofemoral ligament (MPFL) reconstruction, trochleoplasty, lateral release, and three-dimensional transfer of the tibial tuberosity, based on a surgical algorithm. Patellar position and clinical outcomes were evaluated postoperatively. The mean follow-up time was 41.5 months (range: 24-72 months).

RESULTS

Patellar position altered from 1.31 (1.21-1.53) preoperatively to 0.88 (0.69-1.06) postoperatively on the Caton-Deschamps Index (p<0.01). The tibial tuberosity-trochlear groove (TT-TG) distance altered from 21.8mm (20.1-25.8mm) to 10.3mm (5.1-14.7mm), and patellar tilt ranged from 28.1° (21-40°) to 14.6° (5-28°), respectively (p<0.01). Clinical outcomes on the Lysholm and Kujala scales improved from 43.1 and 38.4 to 86.7 and 78.3, respectively, at final follow-up (p<0.01). Surgical treatment that included trochleoplasty resulted in better outcomes than other surgical combinations without trochleoplasty (p<0.05). Sulcus angle and postoperative patellar tilt improved more in those who underwent trochleoplasty than in those who did not (p<0.05).

DISCUSSION

Surgical treatment for patellar instability with patella alta in middle-aged patients resulted in improved clinical outcomes. In particular, a combination surgery including trochleoplasty resulted in the greatest improvement in case of severe trochlear dysplasia.

Treatment of supragastric belching with cognitive behavioral therapy improves quality of life and reduces acid gastroesophageal reflux

OBJECTIVES

Excessive supragastric belching (SGB) manifests as troublesome belching, and can be associated with reflux and significant impact on quality of life (QOL). In some GERD patients, SGB-associated reflux contributes to up to 1/3 of the total esophageal acid exposure. We hypothesized that a cognitive-behavioral intervention (CBT) might reduce SGB, improve QOL, and reduce acid gastroesophageal reflux (GOR). We aimed to assess the effectiveness of CBT in patients with pathological SGB.

METHODS

Patients with SGB were recruited at the Royal London Hospital. Patients attended CBT sessions focused on recognition of warning signals and preventative exercises. Objective outcomes were the number of SGBs, esophageal acid exposure time (AET), and proportion of AET related to SGBs. Subjective evaluation was by patient-reported questionnaires.

RESULTS

Of 51 patients who started treatment, 39 completed the protocol, of whom 31 had a follow-up MII-pH study. The mean number of SGBs decreased significantly after CBT (before: 116 (47-323) vs. after 45 (22-139), P<0.0003). Sixteen of 31 patients were shown to have a reduction in SGB by >50%. In patients with increased AET at baseline, AET after CBT was decreased: 9.0-6.1% (P=0.005). Mean visual analog scale severity scores decreased after CBT (before: 260 (210-320) mm vs. after: 140 (80-210) mm, P<0.0001).

CONCLUSIONS

Cognitive behavioral therapy reduced the number of SGB and improved social and daily activities. Careful analysis of MII-pH allows identification of a subgroup of GERD patients with acid reflux predominantly driven by SGB. In these patients, CBT can reduce esophageal acid exposure.

Tumor immune microenvironment and nivolumab efficacy in EGFR mutation-positive non-small-cell lung cancer based on T790M status after disease progression during EGFR-TKI treatment

Background

The efficacy of programmed death-1 blockade in epidermal growth factor receptor gene (EGFR) mutation-positive non-small-cell lung cancer (NSCLC) patients with different mechanisms of acquired resistance to EGFR tyrosine kinase inhibitors (TKIs) is unknown. We retrospectively evaluated nivolumab efficacy and immune-related factors in such patients according to their status for the T790M resistance mutation of EGFR.

Patients and methods

We identified 25 patients with EGFR mutation-positive NSCLC who were treated with nivolumab after disease progression during EGFR-TKI treatment (cohort A). Programmed death-ligand 1 (PD-L1) expression and tumor-infiltrating lymphocyte (TIL) density in tumor specimens obtained after acquisition of EGFR-TKI resistance were determined by immunohistochemistry. Whole-exome sequencing of tumor DNA was carried out to identify gene alterations. The relation of T790M status to PD-L1 expression or TIL density was also examined in an independent cohort of 60 patients (cohort B).

Results

In cohort A, median progression-free survival (PFS) was 2.1 and 1.3 months for T790M-negative and T790M-positive patients, respectively (P = 0.099; hazard ratio of 0.48 with a 95% confidence interval of 0.20-1.24). Median PFS was 2.1 and 1.3 months for patients with a PD-L1 expression level of ≥1% or <1%, respectively (P = 0.084; hazard ratio of 0.37, 95% confidence interval of 0.10-1.21). PFS tended to increase as the PD-L1 expression level increased with cutoff values of ≥10% and ≥50%. The proportion of tumors with a PD-L1 level of ≥10% or ≥50% was higher among T790M-negative patients than among T790M-positive patients of both cohorts A and B. Nivolumab responders had a significantly higher CD8+ TIL density and nonsynonymous mutation burden.

Conclusion

T790M-negative patients with EGFR mutation-positive NSCLC are more likely to benefit from nivolumab after EGFR-TKI treatment, possibly as a result of a higher PD-L1 expression level, than are T790M-positive patients.
