Low TSH and low T3 hormone levels as a prognostic for mortality in COVID-19 intensive care patients.

Introduction: Coronavirus diasease 2019 (COVID-19) can cause both pulmonary and systemic inflammation, potentially determining multi-organ dysfunction. The thyroid gland is a neuroendocrine organ that plays an important role in regulating immunity and metabolism. Low serum levels of thyroid hormones are common in critical disease situations. The association between low thyroid hormone levels and mortality in COVID-19 intensive care patients has yet to be studied. Aim: The aim of this study is to compare thyroid hormone levels between patients in the general intensive care unit (ICU) to patients in the COVID-19 ICU. Methods: This was a retrospective comparative study of 210 patients who were hospitalized at Ziv Medical Center in the general ICU and in the COVID-19 ICU. Clinical and demographic data were collected from patient's electronic medical records. Results: Serum thyroid hormone levels of Thyroid Simulating Hormone (TSH), T4, and T3 were significantly lower in COVID-19 intensive care unit patients compared to the patients from the general intensive care unit (p < 0.05). The mortality rate in the COVID-19 ICU (44.4%) was higher compared to that in the general ICU (27.3%) (p < 0.05). No significant statistical difference was observed between the two groups in terms of gender and recorded comorbidities of diabetes mellitus, cerebral vascular accident, kidney disease, and cancer. Conclusions: Low serum thyroid hormone levels-T3, T4, and TSH-in COVID-19 ICU patients are associated with higher mortality and could possibly be used as a prognostic factor for mortality among COVID-19 ICU patients. Thyroid hormone levels should be a part in the routine evaluation of COVID-19 ICU patients.

Thyroid US-guided FNA techniques: A prospective,randomized controlled study.

BACKGROUND: Thyroid nodules are common in the general population. Ultrasonography is the most efficient diagnostic approach to evaluate thyroid nodules. The US FNAC procedure can be performed using either the short axis (perpendicular), or a long axis (parallel) approach to visualize the needle as it is advanced toward the desired nodule. The main aim of this study was to compare the percentage of non-diagnostic results between the long and short axis approach. METHODS: A prospective study that included a randomized controlled trial and was divided into two arms-the short axis and the long axis-was conducted. A total of 245 thyroid nodules were collected through the fine needle aspiration cytology, performed with ultrasound, from march 2021 to march 2022. The patient's demographic information were collected and also nodules characteristics. RESULTS: Of 245 nodules sampled, 122 were sampled with the long axis method, while 123 with the short axis method. There is not significantly less non diagnostic approach with either method compared to the other (11.5 % vs 16.3 % respectively). DISCUSSION: Previous studies came to the conclusion that the long axis method yields fewer non diagnostic samples. This study evaluated the two FNA approaches which were proceeded by the same physician who is expert in both techniques. CONCLUSION: The US FNAC performed in the long axis approach will not produce more conclusive results and less non diagnostic results (Bethesda category 1) than the short axis approach one.

Does acute isolated sphenoidal sinusitis meet the criteria of the recent acute sinusitis guidelines, EPOS2020?

INTRODUCTION: Isolated sphenoidal sinusitis (ISS) is a rare disease with non-specific symptoms and a potential for complications. Diagnosis is made clinically, endoscopically, and with imaging like CT scans or MRIs. This study aimed to evaluate if ISS meets the EPOS 2020 criteria for diagnosing acute rhinosinusitis and if new diagnostic criteria are needed. MATERIALS AND METHODS: The study analyzed 193 charts and examination records from 2000 to 2022 in patients diagnosed with isolated sphenoidal sinusitis at the Ziv Medical Center in Safed, Israel. Of the 193, 57 patients were excluded, and the remaining 136 patients were included in the final analysis. Patients were evaluated using Ear, Nose and Throat (ENT), neurological and sinonasal video endoscopy, radiological findings, demographic data, symptoms and signs, and laboratory results. All these findings were reviewed according to the EPOS 2020 acute sinusitis diagnosis criteria and were analyzed to determine if ISS symptoms and signs fulfilled them. RESULTS: The patients included 40 men and 96 women, ranging in age from 17 to 86 years (mean ± SD, 37 ± 15.2 years). A positive endoscopy and radiography were encountered in 29.4%, and headache was present in 98%; the most common type was retro-orbital headache (31%). The results showed that there is no relationship between the symptoms of isolated sphenoidal sinusitis and the criteria for diagnosing acute sinusitis according to EPOS 2020. CONCLUSION: ISS is an uncommon entity encountered in clinical practice with non-specific symptoms and a potential for complications. Therefore, the condition must be kept in mind by clinicians, and prompt diagnosis and treatment must be initiated. This kind of sinusitis does not fulfill the standard guidelines for acute sinusitis diagnosis criteria.

Acupuncture Effect on Analgesic Consumption and Cortisol Levels Following Total Knee Arthroplasty: A Randomized Controlled Trial.

Objective: Pain following total knee arthroplasty (TKA) is common. Various modalities of treating orthopedic postoperative pain (POP) exist; however, the optimal management of POP remains unclear. The purpose of this study was to examine acupuncture's effect on postoperative analgesic consumption and cortisol levels in patients undergoing TKA. Materials and Methods: In this randomized controlled trial, 80 patients scheduled for elective TKA surgery were recruited and randomly assigned to 2 groups: (1) an intervention group, receiving acupuncture treatment on days 1 and 2 in addition to standard POP management (n = 40) and a control group, who received standard POP management only (n = 40). Results: There was no statistical difference between the groups in analgesic consumption on days 1 and 3 postoperatively. On day 5 postoperatively, lower analgesic consumption was seen in the intervention group, compared to the control group. However, this difference was not statistically significant (1.4 versus 2.3, respectively; P = 0.215). There was no statistical difference between the groups in cortisol levels on day 1 postoperatively. In contrast, on day 2 postoperatively, cortisol level was significantly lower in the intervention group, compared to the control group (296 nmol/L versus 400 nmol/L, respectively; P < 0.05). Conclusions: The findings suggest that acupuncture may have some effect on patients' analgesic consumption short-term after TKA. Further studies with larger samples are required for establishing these results.This trial was registered at ClinicalTrials.gov (Registration #: NCT03415204).

The "Vestibular Eye Sign"-"VES": a new radiological sign of vestibular neuronitis can help to determine the affected vestibule and support the diagnosis.

INTRODUCTION: Nystagmus is a valuable clinical finding. Although nystagmus is often described by the direction of its quick phases, it is the slow phase that reflects the underlying disorder. The aim of our study was to describe a new radiological diagnostic sign called "Vestibular Eye Sign"-VES. This sign is defined as an eye deviation that correlates with the slow phase of nystagmus (vestibule pathological side), which is seen in acute vestibular neuronitis and can be assessed on a CT head scan. MATERIALS AND METHODS: A total of 1250 patients were diagnosed with vertigo in the Emergency Department at Ziv Medical Center (ED) in Safed, Israel. The data of 315 patients who arrived at the ED between January 2010 and January 2022 were collected, with criteria eligible for the study. Patients were divided into 4 groups: Group A, "pure VN", Group B, "non-VN aetiology", Group C, BPPV patients, and Group D, patients who had a diagnosis of vertigo with unknown aetiology. All groups underwent head CT examination while in the ED. RESULTS: In Group 1, pure vestibular neuritis was diagnosed in 70 (22.2%) patients. Regarding accuracy, VES (Vestibular Eye Sign) was found in 65 patients in group 1 and 8 patients in group 2 and had a sensitivity of 89%, specificity of 75% and a negative predictive value of 99.4% in group 1-pure vestibular neuronitis. CONCLUSION: VN is still a clinical diagnosis, but if the patient undergoes head CT, we suggest using the "Vestibular Eye Sign" as a complementary sign. As per our findings, this is a valuable sign on CT imaging for diagnosing the pathological side of isolated pure VN. It is sensitive to support a diagnosis with a high negative predictive value.

Kaposi sarcoma at the base of the tongue in a renal transplant patient.

Oral Kaposi Sarcoma (OKS) commonly occurs in patients with AIDS. The incidence of Kaposi sarcoma (KS) is greatly increased in renal transplant recipients compared with the general population, with particular prevalence in certain ethnic groups where it can occur in up to 5% of transplant recipients. From them, only 2% can manifest first with OKS.A man in his early 40s, 2 years after kidney transplantation, presented with a reddish-purple hypertrophic ulcerated lesion at the base of the tongue. Cervical ultrasonography revealed enlarged lymph nodes, and pathological examination of biopsies revealed KS. The patient had HIV-negative status. Following an investigation, calcineurin inhibitor treatment was stopped, and an mTOR (mammalian target of rapamycin) inhibitor treatment was started. Fibreoptic examination 3 months after beginning mTOR inhibitor treatment revealed no traces of the disease in the base of the tongue.An isolated oral lesion should not distract clinicians from further systemic investigation for metastatic disease.OKS is a rare but serious complication in kidney transplant patients after receiving calcineurin inhibitor that could result in airway obstruction due to mass effect or bleeding and aspiration.Early diagnosis and management of OKS in a renal transplant patient who received a calcineurin inhibitor carry a good prognosis. OKS can be managed by changing the treatment regime to an mTOR inhibitor followed by radiation therapy. This contrasts with KS treatment in non-renal transplant patients without calcineurin inhibitors who may need treatment using different modalities such as surgery and chemotherapy.We emphasise the importance of this case for nephrologists responsible for patient follow-up after renal transplantation who prescribed calcineurin inhibitors. These patients must be advised that if they feel any physical mass in the tongue, they should immediately seek an examination by an ear, nose and throat specialist. Nephrologists and patients should be aware that these symptoms should not be underestimated.

Ultrasound-Guided Fine Needle Aspiration of Deep Thyroid Nodule: Is There a Correlation between the Nodule's Depth and Nondiagnostic Results?

Objective: To evaluate whether thyroid nodule depth correlates with nondiagnostic results in ultrasound-guided fine needle aspiration cytopathology. Background: Many factors correlate with nondiagnostic ultrasound-guided fine needle aspiration cytology (FNAC) results, including older age, macrocalcification, small-sized nodules, aspirin medication, and cystic portion in more than 50% of the thyroid nodules. However, there are few studies which have examined whether there is a relationship between the depth of nodules and the percentage of nondiagnostic results in cytology (Bethesda category I). We conducted this study in order to investigate if such a correlation exists. Materials and Methods: FNAC was performed on 283 thyroid nodules between January 2019 and December 2020. Cytological analyses of the nodules were reviewed and sorted as nondiagnostic and diagnostic according to the Bethesda score. Patient files and ultra sound (US) scans were reviewed for clinical information (such as age, sex, and ethnic group) and sonographic features of nodules (such as depth, size, cystic portion, type of calcification, and echogenicity) and were compared between the nondiagnostic and diagnostic nodule results. The depth of a nodule was calculated as the shortest distance from the skin to the most superficial border of the nodule in the axial plane, using our medical center's computer program, which allows reviewing all saved shots of the US scan. Results: Age, sex, and ethnicity were not significantly different between the nondiagnostic group and the diagnostic group (p > 0.05). Nodule diameter, cystic portion, calcification, and echogenicity were also not associated with the frequency of nondiagnostic results. The depth of nodules ≥9 mm was correlated with nondiagnostic US-guided FNA cytological results (OR = 2.55, p=0.018). Conclusions: Deep thyroid nodules correlated with nondiagnostic US-guided FNA cytological results. Further studies are needed for optimizing the approach to deep thyroid nodules in order to improve the efficacy of FNA in deep thyroid nodules.

US-guided FNA techniques for thyroid nodules is the short axis better than the long axis?

BACKGROUND: Ultrasound-guided fine needle aspiration cytology (FNAC US) has been proven to be an accurate and efficient tool in thyroid nodule evaluation. Thyroid nodule aspiration can be acquired with either of two techniques: the short axis, in which only the tip of the needle is observed, and the long axis, in which the entire length of the needle is observed. Our retrospective study aimed to compare the adequacy of the two techniques. METHODS: FNAC US was performed in 538 thyroid nodules between January 2019 and December 2021. Data on the technique and the diagnostic accuracy were collected. RESULTS: A total of 273 nodules were aspirated using the long axis technique, and 265 nodules were aspirated using the short axis technique. The diagnostic adequacies of the long axis technique were significantly higher than those of the short axis technique (92 % versus 86 %, respectively, p < 0.025). CONCLUSION: In our study, the long axis technique provided more accurate cytological evaluation than the short axis technique. LEVEL OF EVIDENCE: level 3.

Pembrolizumab as a first line therapy in a patient with extensive mucoepidermoid salivary gland carcinoma. A complete clinical, radiological and pathological response. A very specific case.

BACKGROUND: Patients with advanced salivary gland malignancies (SGCs) have few therapy options. Although results from newly published trials suggest that checkpoint inhibition may be useful in a subgroup of patients, there are no clear criteria for PD-L1 score in SGCs. Chemotherapy benefits were observed to be limited, with a dismal prognosis in unresectable and high-grade SGC. Immunotherapies have demonstrated extraordinary efficacy in a variety of cancers, including non-small cell lung cancer and malignant melanoma. Anti-PD-1 antibody pembrolizumab has been shown to have potent anti-tumor action in a number of clinical trials. CASE PRESENTATION: We report a unique case of advanced high grade mucoepidermoid carcinoma of the parotid salivary gland after Pembrolizumab treatment as a first line therapy. The tumor was downstaged as a result of the pembrolizumab treatment, allowing for a successful surgical excision with no facial nerve sacrifice and no major neoadjuvant treatment adverse effects, and the final specimen pathology was tumor-free. In these types of malignancies, a similar technique resulted in a complete response (CR) radiologically and pathologically has never been discussed before. CONCLUSIONS: In pretreated patients with high-grade salivary gland mucoepidermoid carcinoma, pembrolizumab showed good anticancer activity and provided a clinically, radiologically, and pathological response with a viable treatment choice. More research is needed to bring Pembrolizumab to the front-line of treatment. The time and duration of medication should be compared to the time required for surgery in these investigations.

Mobile Technology-Based Real-Time Teleotolaryngology Care Facilitated by a Nonotolaryngologist Physician in an Adult Population.

OBJECTIVES: Telehealth can improve access to specialist care. Very few reports of the use of smartphones for teleotolaryngology exist. The objective of this study is to evaluate the use of mobile teleotolaryngology facilitated by a nonotolaryngologist physician. METHODS: A prospective study in adult patients attending a general otolaryngology outpatient clinic. The telehealth encounter with a remote otolaryngologist was facilitated by a final-year medical student simulating a general physician prior to the scheduled visit. The patient and the remote otolaryngologist rated their satisfaction with the encounter. The remote otolaryngologist formulated a diagnosis and rated the level of certainty of this diagnosis. Diagnoses from the telehealth encounter and the face-to-face encounter were compared. RESULTS: Forty-eight patients with an average age of 42.5 years participated in this study. In 79.2% of the consultations, there was concordance between the diagnoses. The average patient and remote otolaryngologist satisfaction with the encounter was 9.5 ± 0.9 and 8.7 ± 1.3, respectively. Twenty-four of the 48 visits (50%) were defined as unnecessary. In the otology group, concordance rates and rates of preventable visits were highest. CONCLUSIONS: Synchronous telehealth consultations, facilitated by a general physician, can be an alternative to visiting a general otolaryngology clinic, especially for otologic patients.

Application-Based Hearing Screening in the Elderly Population.

OBJECTIVES: The effects of age-related hearing loss are severe. Early detection is essential for maximum benefit. However, most hearing-impaired adults delay obtaining treatment. Diagnostic hearing testing at an appropriate facility is impractical, and new methods for screening audiometry aim to provide easy access for patients and reliable outcomes. The purpose of this study was to examine the accuracy of application-based hearing screening in an elderly population. METHODS: The uHear application was downloaded to an iPad. Application-based hearing screening was performed in a non-soundproofed quiet room, and subsequently all participants underwent full diagnostic audiometry in a soundproof booth. RESULTS: Sixty patients were recruited and completed both tests. Significant differences were observed between the hearing results obtained with the application and the standard audiogram at all frequencies and in both ears. Following subtraction of a constant factor of 25 dB from the application-based results in order to compensate for ambient noise, no significant differences in pure tone average were found between the 2 methods. CONCLUSIONS: The uHear application is inaccurate in assessing hearing thresholds for screening in the elderly. However, when site-specifically corrected, the uHear application may be used as a screening tool for hearing loss in an elderly population.

Parents reported higher satisfaction rates when children recognised hospital staff from photographs placed in prominent locations.

AIM: Improved communication with staff during a child's hospitalisation is an important determinant of family satisfaction. We examined whether displaying staff photographs in prominent locations would help children and their parents or guardians to recognise staff and whether this enhanced identification would improve parental satisfaction with their child's hospitalisation. METHODS: No photographs were displayed during the first part of the study. During the second part of the study, staff photographs were placed in prominent locations throughout the paediatric ward. Parents filled in a satisfaction questionnaire on discharge, and the children and their parents were asked how many staff members they could name. RESULTS: The children named a significantly larger number of staff members in phase two than phase one, while the parents' score was unchanged. Overall parental satisfaction was significantly higher in phase two. The parent's age, the duration of the child's hospitalisation and taking part in phase two of the study were significant predictors of parental satisfaction. CONCLUSION: When children were more able to recognise and name hospital staff, this indirectly improved parental satisfaction, even if the number that parents could identify remained unchanged. Displaying staff photographs is a simple way of increasing parental satisfaction during a child's hospitalisation.

Video-otoscopy in children and patient-centered care: A randomized, controlled study.

OBJECTIVES: Medicine today is moving towards patient centered care and patient empowerment. This enhances patient autonomy, allows shared decision making and increases satisfaction. Current technology enables the caregiver to share visual data with the patients, making them more active participants in a medical encounter. It has been shown that higher patient satisfaction rate has a positive effect on outcome and patient compliance. Otoscopic examination is one of the most common procedures performed in the pediatric population. Video-otoscopy uses endoscopic technology to project the image of the tympanic membrane onto a monitor visible to both the physician and the patient. The objective of this study is to assess whether video-otoscopy used in a pediatric emergency department can improve patient-centeredness and parental satisfaction with treatment. METHODS: A randomized, controlled study comparing video-otoscopy with conventional otoscopy was performed. Patients were randomized into 2 groups. In one, ear examination was performed by video-otoscopy and in the other by conventional otoscopy. Following examination, parents in both groups were asked to fill a questionnaire regarding their satisfaction with the otoscopic examination and the patient-centeredness of the encounter. RESULTS: 60 children were recruited and were randomized into two groups: 30 in the video-otoscopy group and 30 in the conventional otoscopy group. Parental satisfaction was significantly higher in the video-otoscopy group. The level of patient-centeredness was significantly higher in the video-otoscopy group. There was a positive correlation between patient-centeredness and parental satisfaction in both groups, with a significantly higher correlation in the video-otoscopy group. CONCLUSIONS: Video-otoscopy was found to encourage patient-centered care and increase parental satisfaction with otoscopy. There is a significantly higher positive correlation between patient-centeredness and parental satisfaction when video-otoscopy is used.

Acupuncture for posttonsillectomy pain in children: a randomized, controlled study.

BACKGROUND: Surgeons have searched for the technique or medication that will produce a 'painless tonsillectomy'; however, this seems to be an impossible goal. Previous studies have shown that perioperative acupuncture may be a useful adjunct for acute postoperative pain and that acupuncture, in addition to nonsteroidal anti-inflammatory drugs, is effective in adults for the treatment of postoperative swallowing pain after tonsillectomy. Acupuncture has been shown to be safe in children. A retrospective review of acupuncture for posttonsillectomy pain in juvenile patients showed a significantly reduced pain score immediately after treatment. AIM: To examine whether acupuncture, in addition to conventional analgesic treatment, will be effective in the treatment of posttonsillectomy pain in children. METHODS: We conducted a randomized, controlled, single-blinded study comparing conventional postoperative analgesic treatment with the same regime plus acupuncture to assess whether postoperative treatment of children aged 3-12 years undergoing tonsillectomy with acupuncture will reduce pain and to examine possible unwanted effects of this treatment. RESULTS: Sixty children were recruited and randomly divided into a study group and a control group. The results indicate that in the study group, there was less pain, less analgesic drug consumption, and higher patient/parent satisfaction with analgesic treatment scores. No adverse effects were recorded. CONCLUSIONS: Acupuncture, in addition to conventional analgesic treatment, is an effective treatment for posttonsillectomy pain. Acupuncture is safe and well received by children and their parents.
