Changes in management of head and neck malignancies during the COVID-19 pandemic.

Objective: Despite multiple studies from high-income countries, reports from low- and middle-income countries on the impact of COVID-19 on head and neck cancer care remain sparse. This study aimed to assess the effects of the COVID-19 pandemic on head and neck cancer patients at a tertiary reference centre in Bosnia and Herzegovina. Methods: We included 228 patients with malignant head and neck tumours evaluated and treated between January 1, 2019, and December 31, 2021. Patient demographics, histological characteristics, and treatment modalities were retrospectively obtained and compared between the pre-pandemic period (pre-COVID-19 group) and the period after the implementation of COVID-19 restrictive measures (COVID-19 group). Results: Patients were significantly older during the COVID-19 pandemic. In particular, 63 patients (44.7%) were under 65 and 78 (55.3%) were 65 or older, while in the pre-COVID-19 period, 53 patients (60.9%) were under 65 and 34 (39.1%) were 65 or older (p = 0.017). The pre-COVID-19 and COVID-19 groups did not significantly differ regarding other patient- and tumour characteristics, or primary treatment modalities. Conclusions: During the COVID-19 pandemic, significantly fewer patients were under 65 at the time of initial work-up, potentially reflecting the more enhanced disease-related anxiety of the younger population. Future studies are warranted to address this population's specific educational and psychological needs to ensure appropriate cancer care.

Correlation of localization and size of the parathyroid glands by ultrasound and intraoperative findings in hyperparathyroidism.

Aim To determine a correlation between the localization of the parathyroid gland (PTG), based on ultrasound (US) examination and the operative findings, as well as the correlation between the size of the parathyroid glands measured by ultrasonography (USG) with pathological findings+, and prevalence of enlarged parathyroid glands in various forms of hyperparathyroidism. Methods A total of 83 patients with hyperparathyroidism who had undergone parathyroidectomy over a period of seven years were included in the study. US examinations of the neck and scintigraphy were performed before surgery in 83 and 42 patients, respectively. In the pathohistological analysis, in addition to diagnosis, the size and weight of the parathyroid gland were measured. Results US examination revealed 125 enlarged parathyroid glands and two normal-sized glands. Scintigraphy revealed 52 enlarged and three normal-sized parathyroid glands. Enlarged parathyroid glands were more frequently found in the projection of the lower pole thyroid glands. A significantly higher number of enlarged upper parathyroid glands were found by the operative findings than by US. There was no statistically significant difference in the diagnosis of enlarged parathyroid glands in all three forms of hyperparathyroidism. There was a positive correlation between the size of the parathyroid glands obtained by US and the size of the operative finding (κ=0.51; p=0.00 and p<0.0005, respectively). The relationship between parathyroid gland size measured by ultrasound and pathological analysis showed a positive correlation. Conclusion Ultrasound was useful in evaluating enlarged parathyroid glands, especially in combination with scintigraphy.

Impact of the COVID-19 pandemic on management of surgically treated laryngeal squamous cell carcinoma.

The coronavirus disease 2019 (COVID-19) pandemic has significantly impacted the treatment of cancer patients, particularly in terms of treatment choices. This study aimed to assess the effects of the COVID-19 pandemic on the management of surgically treated laryngeal squamous cell carcinoma (LSCC) patients, focusing specifically on changes in treatment modalities. We retrospectively analyzed the data from 102 patients who underwent surgical treatment for LSCC between January 1, 2019, and December 31, 2021, at our tertiary medical center. Patient demographics, histological characteristics, and treatment modalities were extracted from electronic medical records and compared between two time periods: pre-COVID-19 and during COVID-19, marked by the introduction of the hospital entry triage. Of the total patients, 53 (52%) were in the pre-COVID-19 group, and 49 (48%) were in the COVID-19 group. No significant differences in patient characteristics at the initial work-up were observed between the two groups. However, a significant shift in treatment modalities was noted. Fewer patients received postoperative adjuvant therapy in the COVID-19 group (70.5%) compared to the pre-COVID-19 group (95.5%). Importantly, this change did not significantly impact the one-year overall survival (OS) rates. The reduction in the use of postoperative adjuvant therapy during the COVID-19 pandemic may be attributed to efforts to minimize hospital visits due to the risk of COVID-19 infection. Further research is warranted to validate these findings and to investigate the potential effects of such changes in treatment modalities on the long-term survival.

Hyperparathyroidism: Pathological Diagnosis and Association with Parathyroid Localization.

Background: The most comon patohistological finding in primary hyperparathyroidism is adenoma of the parathyroid gland, followed by hyperplasia and the rarest is carcinoma. However, hyperplasia of the parathyroid glands (PTG) is most commonly found in secondary and tertiary hyperparathyroidism. Objective: To determine the relationship between the localization of the parathyroid glands and pathological diagnosis, as well as the prevalence of individual pathological diagnosis after surgery in patients with hyperparathyroidism. Methods: Analysis of retrospective-prospective database of 79 patiens who underwent parathyreoidectomy for hyperparathyroidism in the 7-year study period. Diagnostic methods were used to identify enlarged parathyroid glands as well as to determine their localization: ultrasound examination, scintigraphy and operative finding. Standard hematoxylin eosin staining was used for pathohistological diagnosis. A correlation analysis between parathyroid gland localization and pathohistological diagnosis was performed. Results: The median age of the patients were 51 age (range 20-73) and 67,1% of the patients were female. In the total number of surgically removed parathyroid glands (182), the most common pathohistological diagnosis was hyperplasia. Parathyroid adenoma was found in 21 cases. Other diagnoses (thyroid nodule / tissue, lymph node, thymus, cancer) were found in 11 cases, while a normal finding was found in 12 glands. Pathohistological diagnosis of hyperplasia and adenoma were more common in the lower parathyroid glands. Using the chi-square test, no association was found between pathohistological diagnosis and localization of enlarged parathyroid glands. Conclusion: The most common pathohistological diagnosis in hyperparathyroidism was hyperplasia and was most commonly found in the inferior parathyroid glands. Adenoma as pathohistological diagnosis is also most commonly found in the lower parathyroid glands, but without statistical significance.

Interobserver variability of cochlear duct measurements in pediatric cochlear implant candidates.

PURPOSE: The objective of the study was to evaluate the proposed cochlear duct length estimation based on the cochlear 'A value'. Furthermore, we assessed the interobserver variability between radiology and otolaryngology attending physicians and otolaryngology trainees. METHODS: Thirteen pediatric cochlear implant candidates were retrospectively analyzed by three otolaryngology physicians (attending physician, second year, and fourth year trainees) and a radiology attending. The cochlear duct length was calculated based on the formula of Grover et al. The differences in acquired measurements between observers were compared using the Wilcoxon matched signed-rank test. RESULTS: The differences in measurements between the attending otolaryngologist and radiologist were not statistically different, while several significant differences were observed with regard to measurements of attending doctors compared to both residents. In particular, a significant difference between the second year otolaryngology resident and otolaryngology and radiology attending was observed for one side (right ear p = 0.034 and p = 0.012, respectively). Moreover, the fourth year resident calculated significantly different cochlear duct measurements when compared to the attending otolaryngologist (left ear p = 0.014) and radiologist (right ear p = 0.047). Interestingly, differently experienced otolaryngology residents provided significantly different measurements for both ears. CONCLUSIONS: Based on these results, cochlear duct length measurement according to the proposed method may be a reliable and cost-effective method. Indeed, otolaryngology training may be sufficient to provide measurements comparable to radiologists. On the other hand, additional efforts should be invested during otolaryngology training in terms of the evaluation of radiological imaging which may increase the capabilities of otolaryngology residents in this regard.
