Background: Nasal obstruction is one of the most common symptoms encountered in the otorhinolaryngology clinic, with diverse etiology including deviated nasal septum (DNS) and sinusitis. When surgical intervention is considered, the referring surgeon must decide whether preoperative imaging is indicated.

Objective: To identify clinical and physical examination predictors associated with significant sinus findings on computed tomography (CT) imaging in patients with nasal obstruction. To define specific factors in the medical history and physical examination of patients with nasal obstruction, which are associated with positive CT findings.

Methods: We conducted a retrospective review of patients presenting with nasal obstruction. We collected demographic data, clinical and physical examination findings, CT imaging results, and surgical outcomes.

Results: A total of 242 patients were included (mean age 38.5 ± 16.8 years, 65.7% male), all of whom underwent CT imaging prior to surgery. On univariate analysis, nasal edema, ostiomeatal complex (OMC) blockage, or edema, were all associated with positive findings from the CT (defined as Lund–Mackay > 3). On multivariate analysis, OMC obstruction or edema were associated with positive CT findings.

Conclusion: A thorough patient history and detailed physical examination are essential for evaluating nasal obstruction and identifying patients who may benefit from preoperative CT imaging. Specific clinical symptoms can indicate chronic sinusitis, thus guiding surgeons to perform preoperative imaging for accurate diagnosis and targeted treatment beyond deviated nasal septum management.

Background: The Global Initiative for Chronic Obstructive Lung Disease (GOLD) recommends a ratio of forced expiratory volume in one second (FEV1) to forced vital capacity (FVC) of less than 70% (FEV1/FVC < 0.7) after bronchodilators as the criteria for obstruction. However, because the FEV1/FVC ratio decreases with age, using a fixed ratio may lead to overdiagnosis of obstruction in the geriatric population. Using the lower limit of normal (LLN) as threshold for obstruction has been suggested.

Objectives: To determine the rate of overdiagnosis using the GOLD criteria compared to LLN in patients aged 60 and older. To find a better threshold with a minimal rate of over- and underdiagnosis.

Methods: The study population included adults aged 60 years and older who performed pulmonary function test (PFT) at Shaare Zedek Medical Center between 2014 and 2019 with results of FEV1/FVC < 0.7.

Results: We included 430 patients aged 60 years and older, 273 males (63.5%) and 157 females (36.5%). Mean age was 72 ± 8 years. Overdiagnosis was found in 35.6% of patients (95% confidence interval 31.1–40.3%) by using the GOLD criteria compared to the LLN. Overdiagnosis was reduced to 6.4% with the 0.65 threshold. The ideal point of the FEV1/FVC ratio where overdiagnosis and underdiagnosis were at their lowest rates was 0.638.

Conclusions: Use of the GOLD criteria for airflow obstruction may be associated with an overdiagnosis of more than 35% in patients older than 60 years. Lowering the FEV1/FVC ratio to < 0.65 might be more accurate in this population.

Background: Nasal obstruction is one of the most common complaints in the practice of rhinology.

Objective: To adapt the Nasal Obstruction Scale Evaluation (NOSE) questionnaire to Hebrew (H-NOSE) and to assess its sensitivity and specificity.

Methods: Candidates for surgical intervention due to isolated nasal obstruction and healthy volunteers (controls) were included in the validation. The English NOSE questionnaire was translated into Hebrew and re-translated for translation validity. Patients completed the H-NOSE questionnaire before and after surgery for nasal obstruction. The same questionnaire was completed by the controls. Test–retest reliability was performed within 2 weeks. Psychometric properties (reliability, reproducibility, validity, and responsiveness) were assessed by a test–retest procedure, internal consistency, correlation to the Hebrew Sino-Nasal Outcome Tool 22 (He-SNOT-22), and response sensitivity.

Results: In total, 179 patients with nasal obstruction and 74 controls completed the questionnaire. Cronbach's alpha score was 0.93 for internal consistency. The receiver operating characteristic curve demonstrated high sensitivity and specificity (< 90%) and area under the curve was 0.97. We found no significant difference in test–retest reliability. The difference between the pre- and postoperative questionnaire scores was highly significant (13.9 ± 4.0 vs. 3.2 ± 4.1, respectively, P < 0.001).

Conclusions: The H-NOSE questionnaire demonstrated reliable internal consistency, sensitivity, specificity, and reliability. The Hebrew version differentiated between patients and heathy controls and was easy to administer. This instrument is useful for Hebrew speaking patients who undergo surgery for nasal obstruction.

Background: Esophageal cancer is comprised of adenocarcinoma and squamous cell carcinoma and is the sixth leading cause of cancer-related mortality worldwide. Upper endoscopy may reveal a partially or completely lumen-occluding mass at diagnosis, yet the prognostic significance of such a presentation is not clear.

Objectives: To investigate whether endoscopic obstructing lesions have a meaning regarding patient prognosis.

Methods: We reviewed upper gastrointestinal endoscopic studies performed over a 20-year period (2000–2020). We compared overall survival, disease stage, histologic criteria, and anatomic location of the lesions in esophagus lumen-obstructing and non-obstructing tumors. Differences between the two groups were statistically evaluated.

Results: Sixty-nine patients were diagnosed with histologically confirmed esophageal cancer. As assessed through endoscopy, 32/69 (46%) patients had obstructive and 37/69 (54%) had non-obstructive cancers. Median survival was significantly shorter in the lumen-obstructing lesions compared with the non-obstructing lesions (3.5 months vs. 10 months, P = 0.001). Female median survival displayed a trend toward shorter survival compared to males (3.5 months vs. 10 months, P = 0.059). There was no statistically significant difference in the percentages of advanced, stage IV disease in the obstructive group and the non-obstructive group (11/32 [34.3%] and 14/37 [37.8%], respectively P = 0.80).

Conclusions: Obstructive esophageal cancers predict shorter median overall survival compared with non-obstructive cancers, without any correlation between obstruction of the lesion and tumor metastatic stage.

A 26-year-old female at 28 weeks of gestation with her fourth pregnancy presented with a 24-hour history of diffuse abdominal pain and distension. In addition, she had nausea, vomiting, and constipation. The pain did not respond to analgesics. She had poor prenatal care during her pregnancy. She had previously had three cesarean deliveries. The first cesarean delivery was due to non-progressive second stage of labor, the second was preterm due to abdominal pain and suspected uterine rupture, and the last was due to the previous cesarean deliveries. In her last previous pregnancy, she presented with recurrent milder abdominal pain, which resolved spontaneously.

On examination, she was afebrile, with normal blood pressure and heart rate. Her abdomen was distended, tympanic, and mildly tender to palpation with no tenderness on the cesarean scar and no peritoneal signs. Her laboratory testing was normal except for mild hypokalemia.

Background: Hypertrophy of the adenoids is common in children. However, the anatomical site makes the adenoids difficult to assess, and studies evaluating the subject are ambiguous, especially with regard to the use of X-ray as an evaluation tool.

Objectives: To compare medical history with clinical, radiological, and endoscopic evaluations of the adenoids and compare obstructed and non-obstructed children relative to the assessment methods.

Methods: A prospective comparative study was conducted with children who were suspected of having enlarged adenoids. All parents completed a medical history questionnaire and patients underwent clinical evaluation based on Nasal Obstruction Index (NOI) scores, radiological assessment based on the lateral neck X-ray adenoid–nasopharynx (A/N( ratio, and endoscopic evaluation based on anatomical relations. Spearman correlations were used for comparison between methods.

Results: We evaluated 36 patients, median age 5.33 years. Correlation measurements for clinical assessment and questionnaire (r = 0.582, P < 0.0001), questionnaire and endoscopy (r = 0.462, P = 0.005), and clinical assessment and nasal endoscopy (r = 0.621, P < 0.0001) were statistically significant. None of the parameters correlated with the radiological findings. A statistically significant difference was found between the obstructed and non-obstructed groups in both questionnaire (P = 0.004) and clinical assessment (P < 0.0001). However, no difference was found in X-ray measurements.

Conclusions: Lateral neck X-ray measurements were not correlated to symptoms, signs, or endoscopic findings. Therefore, medical professionals should use lateral neck radiography when considering adenoidectomy only on a highly selective basis.

Background: Self-expanding metallic stents (SEMS) insertion is an alternative to emergency surgery in malignant colonic obstruction. However, the long-term oncological outcome of stents as a bridge to surgery is limited and controversial.

Objectives: To determine the long-term oncological outcome of stents as a bridge to surgery.

Methods: Data of patients who underwent emergency surgery and endoscopic stent insertion as a bridge to surgery due to obstructing colon cancer at Soroka Medical Center during a 14 year period were collected retrospectively. Preoperative data, tumor staging, and oncological outcomes in terms of local recurrence, metastatic spread, and overall survival of the patients were compared.

Results: Sixty-four patients (56% female, mean age 72 years) were included in the study: 43 (67%) following emergency surgery, 21 stent inserted prior to surgery. A stent was inserted within 24–48 hours of hospital admission. The mean time between SEMS insertion and surgery was 15 days (range 0–30). Most of the patients had stage II (41%) and stage III (34%) colonic cancer. There was no difference in tumor staging and localization between groups. There was no significant difference in disease recurrence between SEMS and surgery groups, 24% and 32%, respectively. Disease-free survival rates were similar between the SEMS group (23.8%) and surgery group (22%). Four year and overall survival rates were 52.4% vs. 47.6%, 33.3% vs. 39.5%, respectively.

Conclusions: SEMS as a bridge to surgery in patients with obstructing colon cancer provide an equivalent long-term oncological outcome to surgery alone.
