ABSTRACT

OBJECTIVE: This study investigates the importance of bone density, surface area, and diameter of anatomical structures of the superior semicircular canal (SSC), lateral semicircular canal (LSC), posterior semicircular canal (PSC), utricle, and saccule in patients diagnosed with superior semicircular canal dehiscence (SSCD). MATERIALS AND METHODS: The bone density, surface area, and diameter of SSC, LSC, PSC, utricle, and saccule were measured and compared between the SSCD group and control group. Fifteen ears in the SSCD group and 60 ears in the control group were evaluated. Additionally, within the SSCD group, the dehiscent and healthy sides were evaluated independently. RESULTS: SSC's bone density was significantly lower in the SSCD group compared to the control group (p = 0.008). No significant differences were found in surface area and diameter between the groups (p > 0.05). While most of the anatomical structures showed no significant difference in bone density between dehiscent and healthy ears (p > 0.05), SSC bone density was significantly lower in affected ears (p = 0.000) in SSCD group. CONCLUSION: Based on the data obtained in this study, bone density and anatomical structure may be useful in patients diagnosed with SSCD.

ABSTRACT

PURPOSE: The purpose of this study was to adapt Modified Falls Efficacy Scale (MFES) into Arabic and determine the reliability and validity of the instrument. MATERIALS AND METHODS: The study was conducted in two phases: (i) translation and adaptation by the systematic approach of the 'forward-back' translation method and (ii) psychometric testing of the Arabic version of the Modified Falls Efficacy Scale among 207 community-dwelling older adults (≥ 60 years). RESULTS: The Arabic version of the Modified Falls Efficacy Scale demonstrated excellent internal consistency (Cronbach's alpha = 0.98) and test-retest reliability scores (ICC = 0.96, 95% CI; 0.95-0.97). And also showed strong correlations with both the Falls Efficacy International (r = -0.82) and the activities-specific Balance Confidence Scale (r = 0.87). Sampling adequacy for factor analysis was proven by a Kaiser-Meyer-Olkin value of 0.962. Goodness-of-fit (GFI) statistics for the model were in the acceptable range (Chi-Square/Degree of Freedom (CMIN/DF) = 2.59, Goodness-of-fit index (GFI) = 0.9, Comparative Fit Index (CFI) = 0.97, Root Mean Square Error of Approximation (RMSEA) = 0.79). CONCLUSION: The Arabic version of the Modified Falls Efficacy Scale has demonstrated excellent psychometric qualities to measure the level of fear of falling.


Modified falls efficacy scale (MFES) is a commonly used scale for assessment of fear of fall in elderlyThe translated and adapted Arabic version of (A-MFES) will enhance the assessment of fear of fall in Arabic older adults, though it is a patient response scaleThis scale can assess the fear of falling in indoor and outdoor activities which makes this scale comprehensive in nature.

ABSTRACT

OBJECTIVE: To search for any morphological variation contributing to aetiopathogenesis and the diagnosis of benign paroxysmal positional vertigo, we measured the sizes of the semicircular canals in patients with and without benign paroxysmal positional vertigo using multidetector computed tomography. METHODS: Cranial bone computed tomography images of 30 benign paroxysmal positional vertigo patients and 30 control patients were acquired with a 128-slice computed tomography scanner and a transverse plane with a thickness of 0.67 mm. The inner diameter, height and width of the canals were measured. RESULTS: The width of the anterior semicircular canals, and the width and height of the posterior semicircular canals of the affected ears in benign paroxysmal positional vertigo patients (n = 30) were significantly greater than in the control patients (n = 90; p = 0.001, p = 0.023, p = 0.003, respectively). CONCLUSION: In benign paroxysmal positional vertigo patients, the posterior and anterior semicircular canals are longer than those in people without benign paroxysmal positional vertigo. These morphological changes may contribute to elucidating the aetiopathogenesis and be used as a radiological sign for diagnosis of benign paroxysmal positional vertigo disease.

ABSTRACT

PURPOSE: The purpose was to evaluate the effect of intrauterine injection of aBMNC on the endometrial function in patients with refractory Asherman's syndrome (AS) and/or thin and dysfunctional endometrium (TE). STUDY DESIGN: This is a prospective, experimental, non-controlled study MATERIAL AND METHODS: The study was carried out between December 2018 and December 2020 on 20 patients, who were of age < 45 years and had oligo/amenorrhea and primary infertility due to refractory AS and/or TE. One hundred ml BM was extracted. aBMNC cells were separated according to generic volume reduction protocol by using the Cell Separation System SEPAX S-100 table top centrifuge system. We have evaluated CD34+, mononuclear cell (MNC), and total nucleated cell (TNC) counts. The transplantation aBMNC was performed by two intrauterine injections at an interval of one week, transvaginally into the endometrial-myometrial junction by an ovum aspiration needle. Midcyclic endometrial thickness (ET) and gestations after transplantation were evaluated. RESULTS: The mean TNC, MNC, and CD34+ cells were 11.55 ± 4.7 × 108, 3.85 ± 2.01 × 108, and 7.00 ± 2.88 × 106 at first injection, respectively, and 6.85 ± 2.67 × 108, 2.04 ± 1.11 × 108, and 3.44 ± 1.31 × 106 at second injection, respectively. The maximum posttransplantation ET was significantly higher than the maximum pretransplantation ET: 2.97 ± 0.48 vs. 5.76 ± 1.19 (mean ± standard deviation, p < 0.01). Twelve patients had frozen-thaw embryo transfers after the study. In 42% (n = 5 of 12) of the patients, pregnancy was achieved. One of the five patients delivered a healthy baby at term. CONCLUSIONS: Autologous BMNC transplantation may contribute to endometrial function in patients with AS and/or TE.

ABSTRACT

Takayasu arteritis (TA) is a large-vessel vasculitis that predominantly affects the aorta and although it usually causes stenosis, aneurysms have been reported in ∼10-25% of the patients. Here, we present a male TA patient with chronic disseminated intravascular coagulation (DIC) as a rare complication of endovascular grafted aortic aneurysm (AA). Chronic DIC usually presents as mild or even hidden clinical symptoms, and early diagnosis of this condition can only be possible with laboratory tests. Due to the silent clinical scenario, this complication should be kept in mind among AA patients with unexplained thrombocytopenia or coagulation abnormalities.

ABSTRACT

STUDY DESIGN: Retrospective cohort. OBJECTIVES: The objective of the study is to evaluate a relationship between idiopathic intracranial hypertension (IIH) and superior semicircular canal dehiscence (SSCD) of bone overlying the superior semicircular canal (SSC). MATERIALS AND METHODS: A total of 57 (114 ears) individuals, 20 of whom were controls and 37 of whom were IIH, were included in the study. Individuals were evaluated with 0.8 mm slice thickness computed tomography (CT) images for SSC bony roof thickness and SSCD. Thickness of the bony roof over the SSC was graded from Grade 1 to Grade 4. Grade 3 was defined as pre-dehiscence and Grade 4 as dehiscence. RESULTS: Bony roof thickness was 1.25 mm in the control group and 0.76 mm in the IIH group. When bony roof thickness was compared between the groups, it was found to be significantly thinner in the IIH group (p = 0.012). In the IIH group, while dehiscence was detected in 25 of 74 ears, no dehiscence was detected in 49 ears. In the control group, while dehiscence was detected in 5 ears, no dehiscence was detected in 35 ears. The difference is statistically significant (p = 0.015). The correlation between bony roof thickness and cerebrospinal fluid (CSF) pressure in the IIH group was not statistically significant (p = 0.343; rho = 0.110). The correlation between bony roof thickness and age in the IIH group was not statistically significant (p = 0.082; rho = - 0.164). CONCLUSION: Increased CSF pressure in patients with IIH may cause chronic, progressive, and irreversible damage to the bone of the SSC and, according to our study, the rate of SSCD was found to be high in IIH patients.

ABSTRACT

Objective: Patients with solid malignancies are more vulnerable to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection than the healthy population. The outcome of SARS-CoV-2 infection in highly immunosuppressed populations, such as in patients with hematological malignancies, is a point of interest. We aimed to analyze the symptoms, complications, intensive care unit admissions, and mortality rates of patients with hematological malignancies infected with SARS-CoV-2 in Turkey. Materials and Methods: In this multicenter study, we included 340 adult and pediatric patients diagnosed with SARS-CoV-2 from March to November 2020. Diagnosis and status of primary disease, treatment schedules for hematological malignancies, time from last treatment, life expectancy related to the hematological disease, and comorbidities were recorded, together with data regarding symptoms, treatment, and outcome of SARS-CoV-2 infection. Results: Forty four patients were asymptomatic at diagnosis of SARS-CoV- 2 infection. Among symptomatic patients, fever, cough, and dyspnea were observed in 62.6%, 48.8%, and 41.8%, respectively. Sixty-nine (20%) patients had mild SARS-CoV-2 disease, whereas moderate, severe, and critical disease was reported in 101 (29%), 71 (20%), and 55 (16%) patients, respectively. Of the entire cohort, 251 (73.8%) patients were hospitalized for SARS-CoV-2. Mortality related to SARS-CoV-2 infection was 26.5% in the entire cohort; this comprised 4.4% of those patients with mild disease, 12.4% of those with moderate disease, and 83% of those with severe or critical disease. Active hematological disease, lower life expectancy related to primary hematological disease, neutropenia at diagnosis of SARS-CoV-2, ICU admission, and first-line therapy used for coronavirus disease-2019 treatment were found to be related to higher mortality rates. Treatments with hydroxychloroquine alone or in combination with azithromycin were associated with a higher rate of mortality in comparison to favipiravir use. Conclusion: Patients with hematological malignancy infected with SARS-CoV-2 have an increased risk of severe disease and mortality.

ABSTRACT

OBJECTIVE: We aim to demonstrate the effect of an isotonic seawater spray containing chamomile liquid extract on symptoms and nasal mucociliary clearance in patients with allergic rhinitis by comparing it with other isotonic seawater nasal washing solutions. METHODS: The study included 123 patients. Based on Allergic Rhinitis and its Impact on Asthma guidelines, mometasone furoate intranasal spray treatment was started for all patients in the group diagnosed with allergic rhinitis. In addition to this treatment, isotonic seawater spray with chamomile liquid extract was added to Group A, isotonic seawater spray to Group B, and isotonic seawater nasal irrigation to Group C. The fourth group (Group D) was given only nasal steroid spray without nasal washing treatment. Before and after treatment in all patients, the Sino-Nasal Outcome Test-22 was performed, and nasal mucociliary clearance times were measured by the saccharin test. RESULTS: The differences in duration of nasal mucociliary clearance and Sino-Nasal Outcome Test-22 values were taken before and after treatment. In Group A, B, C, and D the Sino-Nasal Outcome Test-22 differences were statistically significant (P ≤.001; P ≤ .001; P ≤ .001, and P = .048, respectively). Only Group A and Group B experienced a significant difference in nasal mucociliary clearance times (P ≤ .001; P = .010, respectively). When the Sino-nasal Outcome Test-22 score and nasal mucociliary clearance time differences before and after treatment were compared between all groups, the Sino-Nasal Outcome Test-22 score difference was higher in Group A than in Groups B, C, and D, the differences were found as statistically significant (P = .010; P = .003; P ≤ .001, respectively). The nasal mucociliary clearance time difference was higher in Group A than in Groups C and D, the differences were found as statistically significant (P = .010; P = .001, respectively). CONCLUSION: Isotonic seawater spray containing chamomile liquid extract is seen as a good alternative treatment option for allergic rhinitis patients.

ABSTRACT

AL type amyloidosis is a systemic disease characterized by the accumulation of amyloid fibrils that can affect many organs such as the skin, gastrointestinal tract, heart, lungs, liver, and kidney. The most frequently involved organ in amyloidosis is the kidney, but cardiac amyloidosis with the poor prognosis is amyloid organ involvement. In this study, we present the treatment of a 40-year-old female patient with acute Budd-Chiari syndrome and very severe proteinuria with sequential liver, kidney, and autologous stem cell transplant after the diagnosis of systemic amyloidosis. To reduce the effects of massive proteinuria and very severe hypoalbuminemia, bilateral renal artery embolization was performed first. After the evaluation of the patient, she underwent liver transplant from a deceased donor, and then kidney transplant was performed from her son 1 month later. Afterward, the patient was discharged without any problems and underwent chemotherapy and stem cell transplant for primary AL amyloidosis. She was followed up without any problem in terms of liver, kidney, and stem cell at the 24th postoperative month. This case shows that autologous stem cell transplant after kidney and liver transplant may be a good treatment option in a selected patient with stem cell involvement diagnosed as having AL amyloidosis.

ABSTRACT

The AETHERA trial reported an increased progression-free survival (PFS) when brentuximab vedotin (BV) was used as maintenance therapy in high-risk Hodgkin lymphoma (HL) after autologous stem cell transplantation (ASCT). Thus, we aimed to determine the impact and safety of BV as maintenance after ASCT in real-world patients. Seventy-five patients with relapsed/refractory HL started on BV consolidation therapy after ASCT due to high risk of relapse, between January 2016 and July 2019, from 25 institutions, were included in the study. The median follow-up time was 26 months. The most common high-risk features were primary refractory or relapsed disease <12 months (n = 61), lack of complete response (CR) to the last salvage regimen (n = 51), and having had at least two salvage regimens (n = 29). At the time of analysis, 42 patients completed consolidation courses, and BV was discontinued in 33 patients. Fifty patients had an ongoing response (CR in 41, PR in 6, and SD in 3 patients), 25 had progressed. Ten died in the follow-up, eight with progressive disease and two due to infection while in CR. The 2-year PFS and OS rates were 67.75% (95% confidence interval [CI]: 0.55-0.77) and 87.61% (95% CI: 0.76-0.94), respectively. Seventeen patients (23%) received BV in the pre-ASCT treatment lines, and there was no survival difference between the BV-naïve and BV-exposed groups. The most common adverse events were neutropenia (27%) and peripheral neuropathy (21%). Sixteen patients (21.3%) experienced grade 3 or 4 toxicity. BV was discontinued due to adverse event in 12 patients. Consolidation with BV after ASCT can achieve a 2-year PFS of 67.75% (95% CI: 0.55-0.75) with an acceptable toxicity profile.

ABSTRACT

BACKGROUND: Healthcare chaplains have key roles in providing palliative support to patients and families, and they are well-suited to facilitate advance care planning (ACP). However, empirical data on the roles and responsibilities of chaplains in facilitating ACP are limited. OBJECTIVES: To examine the roles of board-certified healthcare chaplains in ACP in various healthcare settings. METHODS: A cross-sectional, web-based self-report survey was conducted with 585 board-certified chaplains recruited from 3 major professional chaplains' organizations in the U.S. The survey data included chaplains' demographic and professional characteristics, their roles and responsibilities, and responses regarding communication and participation with other healthcare team members in facilitating ACP, including experienced barriers. RESULTS: More participants worked in community hospital settings (42%) and academic medical centers (19.6%) than in any other setting. Over 90% viewed ACP as an important part of their work, 70% helped patients complete advance directives, and 90% helped patients discuss their preferences about end-of-life treatments. Many chaplains were not consistently included in team discussions regarding decision-making, although most chaplains reported that they could always find ways to communicate with their teams. CONCLUSION: Professional board-certified chaplains regularly engage in facilitating ACP discussions with patients and families in various healthcare settings. There is a need to recognize and provide systematic support for the role of chaplains in facilitating ACP conversations and to integrate chaplains into routine interdisciplinary team and family meetings.

ABSTRACT

PURPOSE: To compare the efficacy of topical meropenem and cefepime treatments with respect to moxifloxacin as new treatment options in an experimental Pseudomonas keratitis model. METHODS: Twenty-four rabbits in which keratitis are induced using Pseudomonas aeruginosa were divided into four groups according to treatment options. A solution of 50 mg/mL meropenem was prepared and topically applied to the first group, 50 mg/mL cefepime solution to the second group, topical 0.5% moxifloxacin drop to the third group, and topical isotonic (0.9% saline) solution to the fourth (control) group. The eyes were examined before and after treatment to score the clinical severity. After the subjects were sacrificed, their corneas were excised. To determine the efficacy of treatments, clinical score, bacterial load, and histopathological and immunohistochemical findings were evaluated. RESULTS: When the three treatment groups were compared, there was a significant difference in the colony-forming unit (CFU) value, polymorph-nuclear leukocyte (PMNL) infiltration, and matrix metalloproteinase (MMP)-9 immunoreactivity (P=0.022, P=0.038, and P=0.037, respectively). The CFU values, PMNL infiltration scores and MMP-9 immunoreactivity were significantly lower in the meropenem and moxifloxacin groups compared with the cefepime group (P<0.05 for all). There was no significant difference between the meropenem and moxifloxacin groups in respect of the CFU values, PMNL infiltration, and MMP-9 immunoreactivity (P=0.842, P=0.784, and P=0.699, respectively). CONCLUSION: The results of our study indicate that topical meropenem is at least as effective as topical moxifloxacin in the treatment of Pseudomonas keratitis. The meropenem and moxifloxacin are safer and suitable in the limited corneal invasion than cefepime. Thus, topical meropenem may be an alternative drug in the treatment of this condition. Clinical studies are needed to be conducted to assess this possibility more accurately.

ABSTRACT

BACKGROUND: In countries where frontline drug approval is limited to first-generation proteasome inhibitors or immunomodulatory drugs, relapses have been both more frequent and less durable. We investigated real world data on the efficacy and safety of daratumumab monotherapy among patients with relapsed refractory multiple myeloma (RRMM) from Turkey using a prospective early access program. PATIENTS AND METHODS: A total of 42 patients with RRMM after a minimum of 3 previous lines of proteasome inhibitor/immunomodulatory drug-based treatments were included from 25 centers across Turkey. Daratumumab monotherapy was administered intravenously at a dose of 16 mg/kg weekly (cycles 1-2), on alternate weeks (cycles 3-6), and monthly thereafter. RESULTS: The median daratumumab monotherapy duration was 5.5 months (range, 0.2-28.7 months). The overall response rate was 45.2%, including 14 (33.3%) partial responses, 4 (9.5%) very good partial responses, and 1 (2.4%) complete response. The median duration of response was 4.9 months. The median progression-free survival (PFS) was 5.5 (95% confidence interval, 2.6-8.4 months) with 12- and 18-month PFS rates of 35.7% and 31.0%, respectively. The median overall survival was not reached; the 12- and 18-month overall survival rates were 64.3% and 59.5%, respectively. The depth of response had a significant effect on PFS (log-rank test, P = .026). Overall, of the 76 adverse events reported, 33 (43.4%) were grade ≥ 3; only 4 (9.52%) were grade 3 infusion-related reactions. No infusion-related reactions or adverse events led to treatment discontinuation. CONCLUSION: The present findings from our daratumumab early access program have confirmed the efficacy and safety profile of daratumumab monotherapy in heavily pretreated Turkish patients with RRMM.

ABSTRACT

BACKGROUND: Bone marrow involvement (BMI) affects the lymphoma stage, survival, and treatment. Bone marrow biopsy (BMB) and fluorodeoxyglucose (FDG) positron emission tomography- computed tomography (PET/CT) are useful techniques to detect BMI. Both have advantages and disadvantages. We aimed to identify factors that could be used to predict BMI with positive and negative results on PET/CT compare them with BMB in newly diagnosed patients with lymphoma. METHODS: We included 22 non-Hodgkin and 16 Hodgkin lymphoma patients in this single center study. All patients had PET/CT examination and BMB before treatment. BMI in BMB was reported as negative or positive. Bone marrow was classified into 3 types by FDG uptake on PT/CT; diffuse involvement, focal involvement, and normal bone marrow. RESULTS: PET/CT and BMB results were concordant (7 positive, 15 negative) in 22 patients (57%). We evaluated concordant and discordant patient characteristics and risk-stratified patients for BMI. Our findings suggest that patients with diffuse FDG uptake on PET/CT, especially patients with advanced age and low platelet and white blood cell counts, are likely to have BMI and could potentially forego BMB. Patients with negative PET/CT findings and no significant laboratory abnormalities are very unlikely to have BMI. CONCLUSION: Our results suggest that BMI should not be decided solely based PET/CT or BMB findings. It is reasonable to use both diagnostic assays along with clinical and laboratory findings. PET/CT result, clinical and laboratory findings could be useful for predicting BMI in patient for whom BMB is contraindicated.

ABSTRACT

PURPOSE: To report the feasibility, accuracy, and reliability of volumetric modulated arc therapy (VMAT)-based total-body irradiation (TBI) treatment in patients with acute myeloid leukemia (AML) or acute lymphoblastic leukemia (ALL). MATERIALS AND METHODS: From 2015 to 2018, 30 patients with AML or ALL were planned and treated with VMAT-based TBI, which consisted of three isocenters and three overlapping arcs. TBI dose was prescribed to 90% of the planning treatment volume (PTV) receiving 12 Gy in six fractions, at two fractions per day. Mean lung and kidney doses were restricted less than 10 Gy, and maximum lens dose less than 6 Gy. Quality assurance (QA) comprised the verification of the irradiation plans via dose-volume histogram (DVH) based 3D patient QA system. RESULTS: Average mean lung dose was 9.7 ±â€¯0.2 Gy, mean kidney dose 9.6 ±â€¯0.2 Gy, maximum lens dose 4.5 ±â€¯0.4 Gy, mean PTV dose 12.7 ±â€¯0.1 Gy, and heterogeneity index of PTV was 1.16 ±â€¯0.02 in all patients. Grade 3 or more acute radiation toxicity was not observed. When comparing plan and DVH-based 3D patient QA results, average differences of 3.3% ±â€¯1.3 in mean kidney doses, 1.1% ±â€¯0.7 in mean lung doses, and 0.9% ±â€¯0.4 in mean target doses were observed. CONCLUSION: Linac-based VMAT increased the dose homogeneity of TBI treatment more than extended SSD techniques. Partial cone-beam CT and optical surface-guided system assure patient positioning. DVH-based 3D patient dose verification QA was possible with linac-based VMAT showing small differences between planned and delivered doses. It is feasible, accurate, and reliable.

RESULTS: PET/CT and BMB results were concordant (7 positive, 15 negative) in 22 patients (57%). We evaluated concordant and discordant patient characteristics and risk-stratified patients for BMI. Our findings suggest that patients with diffuse FDG uptake on PET/CT, especially patients with advanced age and low platelet and white blood cell counts, are likely to have BMI and could potentially forego BMB. Patients with negative PET/CT findings and no significant laboratory abnormalities are very unlikely to have BMI. CONCLUSION: Our results suggest that BMI should not be decided solely based PET/CT or BMB findings. It is reasonable to use both diagnostic assays along with clinical and laboratory findings. PET/CT result, clinical and laboratory findings could be useful for predicting BMI in patient for whom BMB is contraindicated.

ABSTRACT

Allogeneic (allo) hematopoietic stem cell transplantation (HSCT) is the only curative option for many malignant and benign hematological disorders. It seems hopeless for patients who relapse after this strategy. In the era of developing breakthrough therapies, we can hope for better, but for patients relapsed after the first allo HSCT probably the best therapy option for long term survival is still another allo HSCT. Interval between first allo HSCT and relapse of primary disease and achievement of complete response after the relapse are the most prominent factors for long time survival for patient after second all HSCT.
