Background: Laryngopharyngeal reflux (LPR) refers to the backflow of acidic stomach content into the larynx, pharynx, and upper aerodigestive tract. The diagnosis of LPR is based on the patient's history and findings of the laryngoscopy associated with LPR. Other possible manifestations consistent with LPR symptoms include laryngeal cancer, vocal fold granulomas, Reinke's space edema, and vocal polyps. In this study, we compared the characteristics of patients with LPR symptoms and incidental laryngeal findings (ILF) in the laryngoscopic evaluation to those without ILF (WILF).

Objectives: Determine the characteristics of LPR-symptomatic patients with ILF versus WILF.

Methods: In this retrospective study, we examined 160 medical charts from patients referred to the otolaryngology clinic at Galilee Medical Center for LPR evaluation 2016–2018. The reflux symptoms index (RSI), reflux finding score (RFS), and demographics of the patient were collected. All patients with a positive RSI score for LPR (RSI > 9) were included, and the profiles of patients with versus without ILF on laryngoscopy examination were compared.

Results: Of the 160 patients, 20 (12.5%) had ILF during laryngoscopy. Most had vocal cord findings such as leukoplakia (20%), polyps (15%), and nodules (20%). Hoarseness, throat clearing, swallowing difficulty, breathing difficulties, and total RSI score were significantly higher in patients with ILF.

Conclusions: Evaluation of LPR symptoms may provide otolaryngologists with a tool to identify patients with other findings on fiberoptic laryngoscopy. A laryngoscopic examination should be part of the examination of every patient with LPR to enable diagnosis of incidental findings.

Background: Signet ring cell carcinoma (SRCC) is classified as an undifferentiated gastric carcinoma with poor prognosis. Early SRCCs are associated with improved prognosis.

Objectives: To describe the outcomes of incidental SRCC.

Methods: In this case series, 900 medical charts of patients with SRCC were screened to identify patients with incidental SRCC, defined as diagnosed in random, non-focal-lesion-targeted biopsies.

Results: Six patients were diagnosed with incidental SRCC and underwent gastrectomy. The final pathology of five patients revealed one or more small foci of early SRCC without lymphovascular invasion. Only one patient had no evidence of malignancy. The median follow-up after surgery was 4.2 years (50 months, range 37–90 months). No deaths or recurrences were recorded during the follow-up period. These results resemble the reported survival rate for early SRCC.

Conclusions: An aggressive surgical approach in incidental gastric SRCC patients is recommended, as they have a chance for long-term survival.

Background: Loss of consciousness (LOC) is one of the most common reasons for seeking neurological advice in clinics and emergency departments. There is considerable difficulty in determining the nature of the events according to patient reports, and collateral history is often difficult to interpret due to multiple versions and observer interpretations.

Objectives: To examine the utility and validity of incidental video recordings (IVR) in the differential diagnosis of LOC.

Methods: In this retrospective study, I included patients with a documented IVR description. Results were divided into three categories: definite approval (IVR conclusion was decisive and congruent with the gold standard test), partial approval (IVR conclusion was decisive and diagnosis was confirmed by treatment response or clinical course), and inconclusive (IVR conclusion was not decisive, no gold standard test was performed, or the gold standard test was either not decisive or incongruent with the IVR).

Results: I evaluated the results of 31 patients with IVR documentation. Overall, in 18 patients (58%), the IVR conclusion was decisive and congruent with the gold standard test. In 8 patients (25.8%), the IVR conclusion was decisive and congruent with the clinical course or treatment response. In 5 patients (16.1%) the IVR was regarded as inconclusive.

Conclusions: IVR have a substantial yield and are highly accurate in the differential diagnosis of LOC, mainly differentiating between epileptic seizures and psychogenic nonepileptic seizures, yet it is utilized in a minority of the patients in real life.

The Oxford-AstraZeneca vaccine ChAdOx1 (AZD1222, Vaxzevria) is playing a crucial role in counteracting the coronavirus disease-2019 (COVID-19) pandemic [1]. Since March 2021, reports of unexpected thrombotic events associated with thrombocytopenia and vaccination have been published [2]. To the best of our knowledge there is only one report about vaccination-associated myasthenia gravis (MG) occurring after a second dose of BNT162b2 (Pfizer-BioNTech)

Background: Mean platelet volume (MPV), an essential component of the complete blood count (CBC) indices, is underutilized in common practice. In recent years, MPV has drawn strong interest, especially in clinical research. During inflammation, the MPV has a higher value because of platelet activation.

Objectives: To verify whether high MPV values discovered incidentally in healthy naïve patients indicates the development or the presence of cardiovascular risk factors, particularly metabolic syndrome and pre-diabetes.

Methods: A cohort study was used to assess the diagnostic value of high MPV discovered incidentally, in naïve patients (without any known cause of an abnormal high MPV, greater than  upper limit of the normal range, such as active cardiovascular diseases and metabolic syndrome).

Results: The mean MPV value in the patient group was 12.3 femtoliter. There was a higher incidence of metabolic syndrome in our research group than in the general population and a non-significant tendency of pre-diabetes. Family doctors more frequently meet naïve patients with high MPV than a hospital doctor. The results of our study are more relevant for him, who should know the relevance of such a finding and search for a hidden pre-diabetes or metabolic syndrome.

Conclusions: High MPV values discovered incidentally in healthy naïve subjects suggest the development or the presence of cardiovascular risk factors, particularly metabolic syndrome and pre-diabetes. No statistically significant association was found between MPV and the presence of cardiovascular disease

Background: Gallbladder (GB) cancer is rare. Most cases are incidentally found in specimens after a cholecystectomy. Cholelithiasis is almost always present when this diagnosis is made. Obesity is a known risk factor for gallstone formation and thus may be related to GB cancer. 

Objectives: To highlight the importance of evaluation of the gallbladder before surgery, resection of the gallbladder whenever required, and screening the resected tissue for malignancy.

Methods: We retrospectively queried a prospectively maintained database of all bariatric procedures during the last 8 years for cases of concomitant laparoscopic sleeve gastrectomy (LSG) and laparoscopic cholecystectomy (LC). Pathologic reports of the gallbladders were reviewed. Demographic data and perioperative parameters were documented. 

Results: Of 2708 patients reviewed, 1721 (63.55%) were females and 987 (36.45%) males. Excluded were 145 (5.35%) who had a previous cholecystectomy. Of the remaining 2563, 180 (7.02%) had symptomatic gallbladder disease and underwent LSG with LC. Of these, two females (BMI 53 kg/m² and BMI 47 kg/m², both age 60) were found by histological examination to have adenocarcinoma in their GB specimens (1.11%). Both were reoperated, which included partial hepatectomy of the GB bed, resection of the cystic stump, lymph node dissection, and resection of the port sites. One patient is doing well, with no evidence of disease at a postoperative follow-up of 4 years. The second patient had recurrent disease with peritoneal spread and ascites 20 months post-surgery and died 18 months later. 

Conclusions: GB cancer is a rare finding in cholecystectomy specimens. The incidence of this entity might be higher in obese older females owing to the higher incidence of cholelithiasis in these patients. 

 

Background: Developments in laparoscopic surgery have rendered it an efficient tool for many complex surgical procedures. In the last few years, laparoscopic adrenalectomy has become a more viable option for removal of adrenal pathology, with many surgeons preferring it to the conventional open technique.

Objectives: To describe the indications, technique, complications and follow-up of patients undergoing laparoscopic adrenalectomy in our department.

Methods: The hospital files of 30 patients who underwent the procedure were reviewed. There were 19 females and 11 males with a mean age of 45 years. Indications for surgery differed and included hypersecreting adenoma, pheochromocytoma, suspected malignancy, and incidentaloma.

Results: Of the 31 laparoscopic adrenalectomies performed, 11 were right, 18 were left, and 1 was bilateral. The conversion rate to an open procedure was 3%. The mean duration of procedure was 120 minutes. Only one patient required blood transfusion. Complications occurred in 20% of patients, all reversible. There was no mortality. Mean hospitalization duration was 3.4 days, and median follow-up 17 months. There were no late complications. All patients operated on for benign diseases are alive.

Conclusions: Laparoscopic adrenalectomy appears to be a useful tool for the treatment of a range of adrenal pathologies.
