A Comparison of the Effects of Dexamethasone and Methylprednisolone, Used on Level-3Intensive Care COVID-19 Patients, on Mortality: A Multi-Center Retrospective Study

Background@#Coronavirus disease 2019 (COVID-19) is often a mild disease, usually manifesting with respiratory complaints, and is sometimes mortal due to multiple organ failure. Hyperinflammation is a known COVID-19 component and is associated with organ dysfunction, disease severity and mortality. Controlling hyperinflammatory response is crucial in determining treatment direction. An important agent in providing this control is corticosteroids. This study aimed to determine whether dexamethasone and methylprednisolone, doses, administration time and duration in COVID-19 treatment are associated with improved treatment outcomes. @*Methods@#This retrospective multicenter study was conducted with participation of 6 healthcare centers which collected data by retrospectively examining files of 1,340 patients admitted to intensive care unit due to COVID-19 between March 2020 and September 2021, diagnosed with polymerase chain reaction (+) and/or clinically and radiologically. @*Results@#Mortality in the pulse methylprednisolone group was statistically significantly higher than that in the other 3 groups. Mortality was higher in older patients with comorbidities such as hypertension, diabetes mellitus, chronic kidney failure, coronary artery disease, and dementia. Pulse and mini-pulse steroid doses were less effective than standard methylprednisolone and dexamethasone doses, pulse steroid doses being associated with high mortality. Standard-dose methylprednisolone and dexamethasone led to similar effects, but standard dose methylprednisolone was more effective in severe patients who required mechanical ventilation (MV). Infection development was related to steroid treatment duration, not cumulative steroid dose. @*Conclusion@#Corticosteroids are shown to be beneficial in critical COVID-19, but the role of early corticosteroids in mild COVID-19 patients remains unclear. The anti-inflammatory effects of corticosteroids may have a positive effect by reducing mortality in severe COVID-19 patients. Although dexamethasone was first used for this purpose, methylprednisolone was found to be as effective at standard doses. Methylprednisolone administered at standard doses was associated with greater PaO 2 /FiO 2 ratios than dexamethasone, especially in the severe group requiring MV. High dose pulse steroid doses are closely associated with mortality and standard methylprednisolone dose is recommended.

Proptosis is associated with thiol-disulfide in patients with Graves' ophthalmopathy

ABSTRACT Objective: Graves' ophthalmopathy (GO) is a vision-threatening finding observed in approximately half of Graves' disease patients. The pathophysiology of GO is unclear, and one of the suspected factors is oxidative stress. In our study, we compared the relationship between proptosis and SH-SS in patients diagnosed with GO. Materials and methods: In this prospective study, 40 recently diagnosed Graves' disease patients with proptosis, 40 recently diagnosed Graves' disease patients without GO and 30 healthy individuals with similar demographic characteristics were included. Serum thiol-disulfide (SH-SS) measurements were performed. Eye examinations were performed by a single ophthalmologist to check for the presence of GO, and proptosis values were recorded with a Hertel exophthalmometer. Results: Total SH values were lower in the group with proptosis than in the other groups (p < 0.05). Total and native SH values were lower in patients without proptosis than in the control group (p < 0.05). Total SH, native SH and SS levels were independently associated with proptosis (p < 0.05). According to this analysis, it was found that increasing SS and decreasing total and native SH levels increased the probability of proptosis by 24.4%, 32.7% and 32.4%, respectively. Conclusion: A decrease in SH, which is a natural antioxidant that protects the body against oxidative stress, and an increase in SS are important signs of oxidative damage. Proptosis and SH-SS are closely related in GO. This may help us detect GO and proptosis in Graves' patients. It can also assist in developing new options for preventing and treating GO.

Is it possible to predict massive bleeding in nulliparous women with placenta previa?

Abstract Objective We evaluated risk factors to determine if there were specific risk factors that could predict massive bleeding in nulliparous women with placenta previa. Methods The participants were classified into two groups. Women with a calculated blood loss ≥ 1,000mL were included in the massive bleeding group. Women without any signs or symptoms related with hypovolemia or with a calculated bleeding volume < 1,000 mL were categorized into the non-massive bleeding group. Results There were 28 patients (40.6%) with massive bleeding and 41 cases (59.4%) with non-massive bleeding. The calculated blood loss and number of cases that required red cell transfusions were statistically different between the groups (< 0.005 and 0.002, respectively). There were no statistically significant differences in terms of maternal or fetal factors, placental location, or delivery characteristics between the two groups. Conclusion We could not determine the predictive features for massive hemorrhage based on clinical features, delivery features, or placental location.

Opioid-free general anesthesia and induced recovery from anesthesia in a patient with myotonic dystrophy type-1: a case report / Anestesia geral sem opioide e recuperação induzida da anestesia em paciente com distrofia miotônica tipo-1: relato de caso

Abstract Myotonic dystrophy type-1 (Steinert disease) is an autosomal dominant, progressive multisystem disease in which myotonic crisis can be triggered by several factors including pain, emotional stress, hypothermia, shivering, and mechanical or electrical stimulation. In this report, dexmedetomidine-based general anesthesia, in combination with a thoracic epidural for laparoscopic cholecystectomy in a patient with Steinert disease, is presented. An Aintree intubation catheter with the guidance of a fiberoptic bronchoscope was used for intubation to avoid laryngoscopy. Prolonged anesthetic effects of propofol were reversed, and recovery from anesthesia was accelerated using an intravenous infusion of theophylline.

Resumo A Distrofia Miotônica (DM) tipo-1 (Doença de Steinert) é uma doença multissistêmica progressiva autossômica dominante em que a crise miotônica pode ser desencadeada por vários fatores, incluindo dor, estresse emocional, hipotermia, tremores e estímulo mecânico ou elétrico. O presente relato descreve anestesia geral realizada com dexmedetomidina em combinação com peridural torácica para colecistectomia laparoscópica em paciente com Doença de Steinert. Para evitar laringoscopia, a intubação traqueal foi realizada utilizando cateter de intubação Aintree guiado por broncofibroscopia óptica. Os efeitos anestésicos prolongados do propofol foram revertidos e a recuperação anestésica foi acelerada pelo uso de infusão intravenosa de teofilina.

Positive heparin/pf4 antibodies and high mortality rate: a retrospective case-series analysis

Abstract Introduction: Heparin-induced thrombocytopenia (HIT) is a potentially lethal complication of unfractionated or low-molecular weight heparin therapy. We aimed to determine the incidence and mortality rate of patients with positive heparin/platelet factor 4 (PF4) antibodies, which is a rapid detection test of HIT. Methods: Coronary artery bypass grafting and mitral and aortic valve surgeries were evaluated. Cardiopulmonary bypass was employed in all patients. The diagnosis of HIT was based on immunological assays. Postoperative complications, mortality rates, and the causes of death were specified in patients with positive heparin/PF4 antibodies. Results: Postoperative thrombocytopenia was detected in 257 patients. Twenty of these patients undergoing open heart surgery were included in the final analysis. Antibodies against heparin/PF4 complex were positive in 20 patients. The mean body mass index was 28.8±2.3 kg/m2, mean value of left ventricular ejection fraction was 48.3±6.7%, cardiopulmonary bypass time was 113.0±35.0 min, aortic cross-clamping time was 88.0±32.7 min, mean intensive care unit length of stay was 10.9±4.9 days, mean preoperative platelet count was 307.250±88528 platelets/microliter, and mean postoperative platelet count was 243.050±89.354 platelets/microliter. The mean duration of heparin exposure was 6.9±2.9 days. The mortality rate was 45% (nine patients) and 1.2% (three patients) in heparin/PF4 complex positive and negative patients, respectively. Conclusion: Although the incidence of HIT was low in patients undergoing open heart surgery, an increased rate of early mortality was observed in patients with positive heparin/PF4 antibodies.

The Psychological Impact of COVID-19 Disease is more Severe on Intensive Care Unit Healthcare Providers: A Cross-sectional Study

Objective@#Fear, anxiety, depression and sleep deprivation are common mental health disorders in COVID-19 disease.We aimed to analyse the risk for healthcare providers during COVID-19 pandemic in a university hospital. @*Methods@#Anesthesiologists, nurses and nurse anesthetists were invited to fill out the survey. The survey was consist of questions from ‘’The Fear of COVID-19 Scale’’, ‘’Patient Health Questionnaire’’ and ‘’Pittsburgh Sleep Quality Index’’ (PSQI). Each question was worth a point. @*Results@#The data of 208 participants were analyzed. Mean age was 29 ± 7.748 years, 72.1% were male, 67.3% were nurses, 62% were working in intensive care units, 38% were in hospital wards, 62% of all participants were living alone. Moderate depression was the most frequently detected outcome (n = 90, 43.3%). Mean The Fear of COVID-19 Scale for all participants was 18.56 ± 7.731. The mean PSQI of patients was 6.18 ± 4.356 with a 45.7% rate of poor sleep quality. PSQI was found significantly higher in nurses (7.1 ± 4.7, p = 0.000). Nurses were the group with the highest deterioration in sleep quality (53.6%, p = 0.003). The rate of moderate-to-severe depressive symptoms was significantly higher in intensive care unit nurses and physicians (p = 0.018). PSQI score was found significantly higher in intensive care unit nurses and physicians than hospital ward co-workers (7.02 ± 4.59 vs. 4.81 ± 3.57 respectively,p = 0.001). A significant positive correlation was observed between PSQI and The Fear of COVID-19 Scale total score in all patients (p ＜ 0.005). @*Conclusion@#Depression, anxiety, fear and sleep disorders may occur in healthcare workers during COVID-19 outbreak. Intensive care unit nurses were at highest risk.

Development of controlled release dexketoprofen tablets and prediction of drug release using Artificial Neural Network (ANN) modelling

Dexketoprofen trometamol (DT) is an active S (+) enantiomer of ketoprofen, and a non-steroidal anti-inflammatory agent. DT has a short biological half-life and the dosing interval is quite short when there is a need to maintain the desirable effect for longer time periods. Consequently, a controlled release DT tablet was designed for oral administration aiming to minimize the number of doses and the possible side effects. Calculations of the parameters for controlled release DT tablets were shown clearly. Controlled release matrix-type tablet formulations were prepared using hydroxypropyl methylcellulose (HPMC) (low and high viscosity), Eudragit RS and Carbopol, and the effects of different polymers on DT release from the tablet formulations were investigated. The dissolution rate profiles were compared and analyzed kinetically. An Artificial Neural Network (ANN) model was developed to predict drug release and a successful model was obtained. Subsequently, an optimum formulation was selected and evaluated in terms of its analgesic and anti-inflammatory activity. Although the developed controlled release tablets did not have an initial dose, they were found to be as effective as commercially available tablets on the market. Dissolution and in vivo studies have shown that the prepared tablets were able to release DT for longer time periods, making the tablets more effective, convenient and more tolerable.

Anesthesia management for a patient undergoing pulmonary endarterctomy without cardiopulmonary bypass

Abstract Pulmonary endarterectomy is a curative procedure for chronic thromboembolic Pulmonary Hypertension. As usual, cardiopulmonary bypass circuit is required. However, there are several complications attributed to extracorporeal circulation. Hemodilution, systemic inflammatory response syndrome and leukocyte sequestration are circulation related complications. The severe forms include Acute Respiratory Distress Syndrome, Acute Lung Injury, myocardial stunning, dysfunction of the right ventricle, coagulopathy, postoperative stroke or renal dysfunction. In this case report, we aimed to give information about perioperative anesthesia and surgical management of pulmonary endarterectomy which was successfully managed without Cardiopulmonary Bypass.

Can Propofol Lead to an Increase in Seizure Threshold Over the Course of Electroconvulsive Therapy?

OBJECTIVE: To evaluate the effects of 2 different dose regimens of propofol (low dose: 25 sn) during the course of ECT in higher propofol doses. Although there was an increase in the seizure threshold over the course of ECT in both groups, this increase was found to be much more pronounced in the high-dose propofol group according to the low-dose propofol group. Longer duration of seizures was observed in the low-dose propofol group. CONCLUSION: Higher doses of propofol in induction of anesthesia can lead to a more progressive rise in seizure threshold than lower doses of propofol.

Anxiety Sensitivity and Quality of Life in Patients with Acne

BACKGROUND: Anxiety sensitivity (AS) is a continuous fundamental fear and defined as extreme fear of anxiety sensations and symptoms. High AS can cause tendency to anxiety disorders. There are many studies evaluating the anxiety in patients with acne; however, AS has not been investigated. OBJECTIVE: We aimed to investigate AS in patients with acne. METHODS: Two hundred and fourteen acne patients and 117 healthy control subjects, aged older than 16 years were enrolled in the study. Severity of acne was evaluated by Global Acne Grading System. The acne patients and healthy controls were asked to complete the anxiety sensitivity index-3 (ASI-3), the Beck anxiety inventory (BAI) and the Turkish version of acne quality of life index. RESULTS: Anxiety and AS levels in acne patients were significantly higher than healthy controls (p<0.001). Quality of life was impaired in acne patients. Quality of life was negatively correlated with anxiety and AS levels in acne patients (p=0.014, p=0.019, respectively). There was no correlation between quality of life and disease severity (p=0.556) and also there was no correlation between psychiatric scale scores (ASI-3, BAI) and disease severity (p=0.147, p=0.871, respectively). CONCLUSION: To our knowledge, our study is the first to report that AS is high in acne patients. Clinically, our results suggest that there might be a relationship between AS and acne. We conclude that further studies are needed in order to clarify the relationship between acne and AS and to investigate the efficacy of cognitive behavioral treatments in acne patients.

The efficacy and safety of phototherapy in geriatric patients: a retrospective study

Abstract: Background: While phototherapy is a well-established treatment for many dermatoses, data from the literature regarding its use in elderly patients are quite limited. Objective: In this study, we aimed to determine the phototherapy indications in geriatric patients and to evaluate the effectiveness and reliability of phototherapy in this group. Methods: This study included 95 patients of 65 years of age and older who were treated in our phototherapy unit between 2006 and 2015. The data for this study were collected retrospectively from patient follow-up forms in the phototherapy unit. Results: Phototherapy was administered to 28 (29.5%) patients for mycosis fungoides, 25 (26.3%) patients foplaque type psoriasis, 12 (12.6%) patients for palmoplantar psoriasis, 12 (12.6%) patients for generalized pruritus, and 18 (19%) for other dermatoses. Of the patients, 64.2% had received a narrowband UVB (NB-UVB), 21.1% oral psoralen UVA (PUVA), and 14.7% local PUVA treatment. A complete response was achieved in 76.9-85.7% of the mycosis fungoides and in 73.71-100% of the psoriasis vulgaris patients treated with NB-UVB and PUVA, respectively. All the patients with generalized pruritus were treated with NB-UVB, and 80% of these patients achieved significant improvement. The erythema rate was found to be 0.43% per session for NB-UVB treatment and 0.46% per session for PUVA treatment as a side effect. Study limitations: The limitations of our study are that it was retrospective and the remission durations of the patients are not known. Conclusion: This study showed that phototherapy is effective and reliable in the elderly population with proper dose increases and close follow-up.

The Evaluation of Contact Sensitivity with Standard and Cosmetic Patch Test Series in Rosacea Patients

BACKGROUND: Rosacea is a common dermatosis characterized by erythema, telangiectasia, papules and pustules. OBJECTIVE: We aimed to evaluate contact sensitivity in the rosacea patients. METHODS: We included 65 rosacea patients and 60 healthy volunteers in the study. The patient and control groups were patch tested with European baseline series and cosmetic series. RESULTS: A positive reaction to at least 1 allergen in the European standard series was found in 32.3% of rosacea patients and 20.0% of subjects in the control group while the relevant numbers were 30.8% of rosacea patients and 10% of controls with the cosmetic series (p=0.08). In total, we found a positive reaction to at least 1 allergen in 38.5% of patients and 25.0% of controls (p=0.15). We did not find a statistically significant relationship between a positive reaction to 1 allergen in total and the gender, skin type, rosacea type, ocular involvement, age and disease duration. There were more symptoms in patients with a positive reaction to allergens (p < 0.001). CONCLUSION: Contact sensitivity was detected more common in rosacea patients. Patch testing may be useful in the treatment and follow up of rosacea patients especially if symptoms such as itching, burning and stinging are present.

Procedural and Early Outcomes of Two Re-entry Devices for Subintimal Recanalization of Aortoiliac and Femoropopliteal Chronic Total Occlusions

BACKGROUND AND OBJECTIVES: Subintimal angioplasty is a common treatment choice for chronic total occlusions (CTO) in the iliac and femoropopliteal arteries. This article describes the technical aspects and early outcomes of two different re-entry devices and comparison with manual re-entry technique. SUBJECTS AND METHODS: A retrospective review of 61 patients (re-entry group) treated with Outback or Pioneer Plus catheters was carried out. A matched cohort of patients (n=62) who underwent lower extremity interventions without the use of re-entry devices (manual re-entry group) were also analyzed (overall 123 patients were analyzed). Procedural success, procedural durations, patency estimates, ankle-brachial indices, and complications were analyzed. RESULTS: Sixty-one patients underwent Outback or Pioneer Plus guided subintimal recanalization. After the procedure, ankle-brachial indices significantly increased in all patients during follow-up. Primary patency for the entire cohort was 83% in the first month. When the re-entry device group was compared with manual re-entry group, no difference was found with respect to success, complication, and patencies between the two groups during follow-up. However, procedure duration and the amount of contrast agent used was significantly decreased in re-entry groups (p<0.001). Also, re-entry time was significantly decreased in Pioneer plus group according to Outback group (p<0.001) CONCLUSION: Recanalization of CTO using re-entry devices for aortoiliac or femoropopliteal arteries is safe and effective. These devices shorten the procedure time, the re-entry time, reduce radiation risk, and reduce the amount of contrast agent employed.

Are treatment guides and rational druguse policies adequately exploited incombating respiratory system diseases?

The aim of the present study was to increase awareness regardingthe rational use of medicines. The data were obtained via the Material ResourcesManagement System Module of the Ministry of Health. For the appropriatenessof treatments, the Global Initiative for Asthma, the Global Initiative for ChronicObstructive Lung Disease, and the guidelines for the rational use of medicines wereused. We also investigated whether any de-escalation method or physical exercisewas performed. Statistical analyses were performed using descriptive statistics todetermine the mean, standard deviation, and frequency. The results showed thathealthcare providers ignored potential drug reactions or adverse interactions, and reflecting the lack of adherence to the current treatment guides, 35.8% irrational useof medicines was recorded. Thus, de-escalation methods should be used to decreasecosts or narrow the antibiotic spectrum, antibiotic selection should consider the resis-tance patterns, culturing methods should be analyzed, and monotherapy should bepreferred over combination treatments

Smell identification scores of patients with essential tremor

It has been reported that patients with essential tremor have a much higher risk of Parkinson’s disease; moreover, olfactory dysfunction is common in Parkinson’s disease and becomes apparent early in the disease process. We aimed to investigate the olfactory function of essential tremor patients using the Short Smell Test Battery of GATA Haydarpaşa (GULTEST), which consists of five odors (banana, lemon, mint, rose, and chocolate). The participants in the study were 155 male essential tremor patients, 20–36 years of age (mean age: 21.2), and 290 male control subjects, 20–35 years of age (mean age: 21.1). The two groups were similar in terms of age, gender, and smoking history; their mean GULTEST scores were 3.41 and 3.4, respectively. Our results showed no loss of olfactory function in young male essential tremor patients.

The Role of Tendinitis in Fibromyalgia Syndrome

Fibromyalgia Syndrome (FS) is a common disease characterized by diffuse, widespread pain and multiple tender points. The syndrome has been subclassified as primary (PFS) and secondary (SFS) fibromyalgia. The aim of this study was to evaluate the role of common tendinitis (rotator cuff tendinitis, bicipital tendinitis, lateral epicondylitis, De-Quervain's tendinitis and pes anserinus tendinitis) in FS. Twenty female patients with PFS, 20 with SFS and 20 female controls, matched by age and body mass index, participated in the study. Existence of common tendinitis was evaluated with specific examination methods. Right and left rotator cuff tendinitis, pes anserinus tendinitis and left lateral epicondylitis were significantly more common in patients with PFS and SFS than in control subjects. As a result, considering the central hyperexcitability present in the fibromyalgia patients, concomitant pathologies such as tendinitis which lead to shoulder, arm, and leg pain must be evaluated. Follow up and therapy for the disease must be planned according to these factors which are not only probable symptoms of FS, but also leading causes for the occurence and continuity of the pain in this disease.
