Stereotactic radiosurgery for brain metastases arising from gynecological malignancies: A retrospective treatment outcome analysis.

BACKGROUND: This retrospective study aims to assess the efficacy of stereotactic radiosurgery (SRS) in the treatment of brain metastases (BM) originating from gynecological cancers. It focuses on local control (LC), distant tumor control (DTC), and overall survival (OS). METHODS: The analysis comprised 18 individuals with gynecological-origin BM treated with SRS at the Hadassah Medical Center from 2004 to 2021. Statistical analyses evaluate factors impacting LC, DTC, and OS. RESULTS: A total of 36 BM of gynecological origin underwent SRS. The median age at the first SRS treatment was 60 years, with a median time of 24.5 months from the primary malignancy diagnosis to BM detection. The 12-month LC rate per patient was 84.6 %, and 5.6 % per BM. Only two instances of local recurrence were observed. The DTC at 12 months was 75 %, with a 29 % overall. Non-significant trends indicating a correlation with distant brain failure with increased cumulative volume and the occurrence of craniotomy before SRS. The median OS of the cohort was 16.5 months from SRS treatment. The 6, 12, 18, and 24-month survival rates were 77.8 %, 66.7 %, 50 %, and 22.2 % respectively. Higher number of BM was associated with lower OS (p = 0.046). On multivariate analysis, age was a significant factor for OS (p = 0.03), demonstrating that older age was associated with a more favorable prognosis. CONCLUSION: This study supports SRS effectiveness for treating BM from gynecological cancers and suggests similar outcomes to more common malignancies.

Subtotal Submucosal Arytenoidectomy with Lateralization Sutures (SMALS) Covered by a Mucosal Flap.

OBJECTIVE: Glottic airway stenosis (GAWS) may result from bilateral paralysis (BVFP) or posterior glottic stenosis (PGS). Since the glottis is the principal airway sphincter, surgeons shift on the balance between airway, aspirations, and voice. We aim to describe our surgical technique and outcome of the SMALS procedure for GAWS correction. METHODS: A retrospective cohort of patients who underwent SMALS for PGS between 2018 and 2021. SMALS involves: endoscopic submucosal subtotal arytenoidectmy (preserving medial mucosal flap) and lateralization sutures. The sutures lateralize the mucosal flap to cover the arytenoidectomy bed without lateralization of the membranous vocal fold; expanding the posterior glottis, while preserving a relatively good voice. Covering the arytenoidectomy bed enhances healing. Medical and surgical data, airway, voice, and swallowing symptoms were collected. Relative glottic opening area (RGOA) and relative glottic insufficiency area (RGIA) were calculated. RESULTS: Eleven PGS patients who underwent 15 SMALS were included (4 bilateral), all patients had post-intubation PGS, 1 patient also had prior radiation to the larynx. All patients were tracheostomy-dependent. There were no major complications. No granulation or retracting scar was observed at follow-up. None had a persistent voice or swallowing disability. Successful outcome (decannulation) was achieved in 8 (73%); RGOA increased in all (Δ = 0.37; p = 0.003), while RGIA remained relatively stable (Δ = 0.02; p = 0.055). CONCLUSIONS: SMALS is a safe and effective, novel modification of the classic arytenoidectomy, for GAWS correction that can be easily applied and may expand the airway without significant glottic insufficiency symptoms.

The Long-Term Implications of Rhinitis and Chronic Rhinosinusitis in Young Adults.

BACKGROUND: The long-term impact of rhinitis and chronic rhinosinusitis (CRS) on general health and medical services utilization in young adults have been limitedly studied. METHODS: A case-control study in the Israeli Defense Forces, between the years 2005 and 2019, of all individuals with either rhinitis or CRS and a matched cohort of healthy individuals with a minimum of 5 years of consecutive follow-up. RESULTS: The study groups included 617 patients with rhinitis and 296 patients with CRS and 2739 healthy controls with an average age of 28 years. During a mean follow-up of 8 years, a significant fraction of patients in both study groups were diagnosed with asthma compared to the control group, (26.1% and 23.3% vs. 3.7%, respectively; CI 95%: 12.1%-14.9%, p < 0.0001). 7.6% of patients with rhinitis developed CRS. Significantly increased loss of productivity and medical system utilization were noted in the study groups compared to controls (p < 0.0001). Moreover, deterioration in general health, manifested as loss of physical fitness for combative service was observed in a third of patients during follow-up. CONCLUSIONS: Rhinitis and CRS significantly impact productivity and medical service utilization in young adults, as well as general health associated with development of asthma and impairment of physical fitness. A minority of rhinitis patients develop CRS overtime, further affecting this patient group. These patients should be followed up and managed to improve disease control and associated outcomes.

Dilation, Steroid Injection, and Cough Exercise for Correction of Posterior Glottic Stenosis.

OBJECTIVE: To describe the DISCO protocol (Dilation, Steroid injection, and post-operative Cough Exercise); a novel treatment for posterior glottic stenosis (PGS). Restoring glottic mobility in PGS is a major challenge. In orthopedic and plastic surgery, post-operative physical therapy is associated with improved motion range and flexibility; yet, this principle was never applied to laryngeal surgery. METHODS: A retrospective cohort of PGS adult patients, treated by the DISCO protocol during 2018-2020. DISCO involves the following: scar release, glottic dilation, and steroid injection, followed by post-operative cough as glottic physical therapy. Maximal glottic opening angle (MGOA), relative glottic opening area (RGOA), and relative glottic insufficiency area (RGIA) were calculated before and post-operatively. RESULTS: Seventeen patients were included; PGS etiology was post-intubation (n = 10), post-irradiation (n = 3), both (n = 1) and joint sclerosis (n = 3). Six patients also had additional airway disorders. Sixteen patients were tracheostomy-dependent. 2 (12%), 8 (47%) and 7 (41%) patients had type II, III and IV stenosis, respectively. Surgery included scar release, dilation and steroid injection alone in 7 patients; and additional unilateral sub-mucosal arytenoidectomy in 10. The mean follow-up was 17.5 months. There were no major complications. Successful outcomes (e.g., decannulation or permanent capping) were achieved in 14 (82%) patients with some restoration of joint movement. None had a persistent voice or swallowing complaints. Both MGOA and RGOA increased in all patients (p < 0.001). RGIA remained unchanged (p = 0.878). CONCLUSIONS: The DISCO protocol is a novel, effective and safe approach for PGS correction that can be easily applied. It can restore vocal fold mobility and may expand the glottic airway without causing glottic insufficiency. LEVEL OF EVIDENCE: 4 Laryngoscope, 133:883-889, 2023.

Retrospective analysis of the role of intra-operative parathyroid hormone monitoring during parathyroidectomy for primary hyperparathyroidism: a single center experience over 2 decades.

PURPOSE: Role of intra-operative parathyroid hormone (IOPTH) monitoring during parathyroidectomy for primary hyperparathyroidism (PHPT) has long been debated. Our main goal was to investigate the cure rates of parathyroidectomy for primary hyperparathyroidism with and without IOPTH monitoring. Our secondary goal was to investigate if operating room time can be saved when IOPTH monitoring is not used. METHODS: A retrospective analysis of patients who underwent parathyroidectomy for PHPT due to a single adenoma between 2004 and 2019 was performed. Cure rates and operating room time were compared. RESULTS: 423 patients were included. IOPTH was used in 248 patients (59%). Four patients were not cured, two from each group, with no significant difference between the groups (98.8% vs. 99.1%, p = 0.725). Surgery time was significantly longer in the IOPTH group, p < 0.001. CONCLUSIONS: There is no advantage for using IOPTH during parathyroidectomy in suitable clinical settings. The procedure may be safely performed without IOPTH while achieving non-inferior success rates and reducing operative time.

Bioelectrical Impedance Analysis in Patients Undergoing Major Head and Neck Surgery: A Prospective Observational Pilot Study.

BACKGROUND: Head and neck patients are prone to malnutrition. Perioperative fluids administration in this patient group may influence nutritional status. We aimed to investigate perioperative changes in patients undergoing major head and neck surgery and to examine the impact of perioperative fluid administration on body composition and metabolic changes using bioelectrical impedance. Furthermore, we sought to correlate these metabolic changes with postoperative complication rate. In this prospective observational pilot study, bioelectrical impedance analysis (BIA) was performed preoperatively and on postoperative days (POD) 2 and 10 on patients who underwent major head and neck surgeries. BIA was completed in 34/37 patients; mean total intraoperative and post-anesthesia fluid administration was 3682 ± 1910 mL and 1802 ± 1466 mL, respectively. Total perioperative fluid administration was associated with postoperative high extra-cellular water percentages (p = 0.038) and a low phase-angle score (p < 0.005), which indicates low nutritional status. Patients with phase angle below the 5th percentile at POD 2 had higher local complication rates (p = 0.035) and longer hospital length of stay (LOS) (p = 0.029). Multivariate analysis failed to demonstrate that high-volume fluid administration and phase angle are independent factors for postoperative complications. High-volume perioperative fluids administration impacts postoperative nutritional status with fluid shift toward the extra-cellular space and is associated with factors that increase the risk of postoperative complications and longer LOS. An adjusted, low-volume perioperative fluid regimen should be considered in patients with comorbidities in order to minimize postoperative morbidity.

Coronary artery bypass grafting after aprotinin: are we doing better?

OBJECTIVE: Cardiac surgery patients are treated with antifibrinolytic agents to reduce intra- and postoperative bleeding. Until 2007, lysine analogues (aminocaproic acid and tranexamic acid) and serine protease inhibitors (aprotinin) were recommended. In 2008, the U.S. Food and Drug Administration prohibited aprotinin use because of associated postoperative complications, including cerebrovascular accidents and renal failure. This work aimed at reevaluating the efficacy and safety of aprotinin versus tranexamic acid in patients undergoing elective coronary artery bypass surgery. METHODS: Two groups were enrolled in this study. Group A (n = 256), operated from January 2005 to August 2007, was treated with the half-Hammersmith aprotinin regime whereas group B (n = 104), operated after 2008, was treated with the full-dose tranexamic acid regime. All patients were of low-risk profile, and underwent an elective, on-pump coronary artery bypass surgery. The main outcome measures were safety, assessed in relation to thrombosis-related cardiac, cerebral, and renal events; and efficacy, investigated in terms of postoperative bleeding and infusions of blood products. RESULTS: Postoperatively, group B demonstrated greater bleeding during the operative and first postoperative days, and total bleeding (P values ≤ .001); a greater requirement of blood and/or blood products infusions (P = .024); higher postoperative acute renal failure rates (P = .028); lower platelet count (P = .002); and a higher postoperative increase in troponin levels (P < .0001). CONCLUSIONS: Among low-risk patients undergoing coronary artery bypass surgery, the half-Hammersmith aprotinin-based antifibrinolytic management proved to be more efficacious in terms of bleeding and consumption of blood products, with no evidence of associated increased rates of postoperative complications. Accordingly, the usage of aprotinin should be reconsidered for treatment among cohorts of low-risk cardiac patients.
