Comparison of the clinical course of COVID-19 infection in sickle cell disease patients with healthcare professionals.

It is highly expected that COVID-19 infection will have devastating consequences in sickle cell disease (SCD) patients due to endothelial activation and decreased tissue and organ reserve as a result of microvascular ischemia and continuous inflammation. In this study, we aimed to compare the clinical course of COVID-19 in adult SCD patients under the organ injury mitigation and clinical care improvement program (BASCARE) with healthcare professionals without significant comorbid conditions. The study was planned as a retrospective, multicenter and cross-sectional study. Thirty-nine SCD patients, ages 18 to 64 years, and 121 healthcare professionals, ages 21 to 53, were included in the study. The data were collected from the Electronic Health Recording System of PRANA, where SCD patients under the BASCARE program had been registered. The data of other patients were collected from the Electronic Hospital Data Recording System and patient files. In the SCD group, the crude incidence of COVID-19 was 9%, while in healthcare professionals at the same period was 23%. Among the symptoms, besides fever, loss of smell and taste were more prominent in the SCD group than in healthcare professionals. There was a significant difference between the two groups in terms of development of pneumonia, hospitalization, and need for intubation (43 vs 5%, P < 0.00001; 26 vs 7%, P = 0.002; and 10 vs 1%, P = 0.002, respectively). Prophylactic low molecular weight heparin and salicylate were used more in the SCD group than in healthcare professionals group (41 vs 9% and 28 vs 1%; P < 0.0001 for both). The 3-month mortality rate was demonstrated as 5% in the SCD group, while 0 in the healthcare professionals group. One patient in the SCD group became continously dependent on respiratory support. The cause of death was acute chest syndrome in the first case, hepatic necrosis and multi-organ failure in the second case. In conclusion, these observations supported the expectation that the course of COVID-19 in SCD patients will get worse. The BASCARE program applied in SCD patients could not change the poor outcome.

Comparative analysis of the patients with community-acquired pneumonia (CAP) and health care-associated pneumonia (HCAP) requiring hospitalization.

INTRODUCTION: The recently introduced concept of health care-associated pneumonia (HCAP), referring to patients with frequent healthcare contacts and at higher risk of contracting resistant pathogens is controversial. MATERIALS AND METHODS: A prospective study comparing patients with HCAP and community-acquired pneumonia (CAP) in the our center. The primary outcome was 30 day mortality. RESULT: A total of the 169 patients HCAP 36 (21.3%); CAP 133 (78.7%) were evaluated. HCAP patients were older than patients with CAP [median age was 72.5 (43-96), 60.0 (18-91) years p<0.05]. The most common Klebsiella pneumoniae (16.6%) and Pseudomonas aeruginosa (8.3%) were gram-negative bacteria in the SBIP group; In the TGP group, gram-positive bacteria were more frequently isolated. Polymicrobial agents (22.2% vs. 3.7% p<0.05) and MDR pathogens (57.1% vs. 24% p<0.05) were more common in patients with HCAP. Mortality rate (22.2% vs. 6% p<0.05) was also higher in HCAP more than CAP. CONCLUSIONS: HCAP was common among patients with pneumonia requiring hospitalization and mortality rate was high. The patients with HCAP were different from CAP in terms of demographic and clinical features, etiology, outcome.

Epidemiology of NIV for Acute Respiratory Failure in COPD Patients: Results from the International Surveys vs. the "Real World".

Non-invasive ventilation (NIV) has been recommended as the  first-line ventilation modality for acute respiratory failure (ARF) due to acute exacerbation of chronic obstructive pulmonary disease (AECOPD) based on strong evidence. However, everyday clinical practice may differ from findings of multiple randomized controlled trials. Physicians and respiratory therapists involved in NIV management have been queried about its utilization and effectiveness. In addition to these estimates, cohort studies and analysis of large inpatient dataset of patients with AECOPD and ARF managed with NIV have been extensively published over the last two decades. This review summarizes the perception of medical staff vs. the "real life" data about NIV use for ARF in AECOPD patients.

A Narrative Review of the Clinical Trials in Sleep-Related Breathing Disorders from 2022 to Present.

Sleep-related breathing disorders (SRBD) comprise obstructive sleep apnea (OSA), central sleep apnea (CSA), obesity-hypoventilation syndrome (OHS), as well as isolated sleep-related hypoxemia (ISRH), according to the recent International Classification of Sleep Disorders 3. During the last decades, there have been cumulative research reports indicating an association between the SRBD and increased cardiometabolic illness and death, as well as decreased quality of life. Notwithstanding, the results have been inconclusive, and the evidence level was not high regarding the effect of treatment for the SRBD on adverse outcomes. In the current work, we aim to give a comprehensive review of the clinical trials published from January 2022 to August 31, 2023. We highlight the heterogeneity of cardiometabolic disorders among adults with SRBD and particularly emphasize OSA management, drug therapy for OSA, positive airway pressure (PAP) therapy and cardiovascular outcomes, other effects of PAP in pregnancy and neurocognitive function, as well as the effects of surgical treatment and oral appliances. We also underline future directions in OSA management, telemonitoring, and druginduced sleep endoscopy in managing the SRBD, especially OSA. We ascertain that more studies are needed within the CSA, OHS, and ISRH research fields.

[Venous thromboembolism in intensive care unit patients]. / Yogun bakim hastalarinda venöz tromboembolizm.

In intensive care units, venous thromboembolism (VTE) is a life threatening, clinically important issue. The diagnosis of VTE is significantly complicated, even in patients except intensive care units and there is no consensus between clinicians about its treatment. The factors such as heterogeneity of intensive care units patients, the association of thrombosis and bleeding risks in the majority of patients, the non-specific signs and symptoms of VTE, the feasibility limitations of diagnostic methods are caused difficulties in the diagnosis and treatment of VTE. In this review, it has been aimed to remind VTE issue in the intensive care units, by review the investigations about the diagnosis, treatment and thromboprophylaxis of VTE.

Change of respiratory functions, the STOP-Bang questionnaire, and Epworth sleepiness scale after bariatric surgery.

INTRODUCTION AND OBJECTIVE: Obesity is a highly morbid and fatal syndrome that reduces respiratory function. Obstructive sleep apnea syndrome (OSAS) is a common sleep disorder in morbid obesity. Herein, we aimed to determine how respiratory function tests changed over time after bariatric surgery and to assess non-PSG (polysomnography) tests, namely STOP-Bang questionnaire and Epworth sleepiness tests, for predicting OSAS risk. METHOD: This retrospectively conducted study enrolled 35 patients who underwent bariatric surgery. Patients were divided into three groups formed on the basis of time passed after surgery (1, 2, or 3 years). Preoperative and postoperative respiratory function test parameters assessed by spirometry, body mass index (BMI), STOP-Bang questionnaire, and Epworth sleepiness test scores were recorded. RESULTS: Twenty-four (68.6%) patients were female, 11 (31.4%) male. The mean age was 36.5±10.5 years. Postoperative weight loss of the study groups was 26% p=0.001, 23.6% p=0.002 and 25.9% p=0.005. Reductions in BMI were 32 kg/m2 p=0.001, 34.5 kg/m2 p=0.002, 35.8 kg/m2 p=0.005 respectively. Postoperative FVC (440 ml, 390 ml, 430 ml p = 0.005) and FEV1 (220 ml p = 0.005, 250 ml p = 0.004, 214 ml p = 0.005) increased in all three groups. STOP-Bang questionnaire and Epworth sleepiness scale scores significantly decreased after weight loss compared to preoperative period in all the study groups. CONCLUSION: We showed that FVC and FEV1 increased in the short and long term after weight loss by bariatric surgery; we also found that STOP-Bang questionnaire and Epworth sleepiness scale scores decreased postoperatively. These tests may be helpful to assess OSAS risk before and after surgery. KEY WORDS: Bariatric surgery, Obesity, Respiratory functions, STOP-Bang questionnaire and Epworth sleepiness test.

Evaluation of Subclinical Atherosclerosis with Carotid Intima-Media and Epicardial Fat Thickness in Patients with Sarcoidosis.

OBJECTIVES: Since many similar mechanisms may play a role in the pathophysiology of sarcoidosis and atherosclerosis, the risk of subclinical atherosclerosis may be increased in patients with sarcoidosis. The aim of this study was to evaluate known markers of subclinical atherosclerosis, namely epicardial fat thickness (EFT) and carotid intima-media thickness (CIMT) in patients with sarcoidosis. MATERIALS AND METHODS: This cross-sectional study included a total of 183 subjects, including 94 patients with sarcoidosis (patient group) and a control group of 89 healthy individuals. Measurements of EFT and CIMT were taken from all subjects and recorded. The groups were compared, and differences were analyzed statistically. RESULTS: EFT was higher in patients than in control subjects (6.42±1.12 mm vs 7.13±1.41 mm, p<0.001). CIMT was higher in patients than in control subjects (0.51±0.02 mm vs 0.52±0.02 mm, p=0.003). CONCLUSION: EFT and CIMT were found to be higher in patients with sarcoidosis than in healthy people. These results indicate that the risk of subclinical atherosclerosis might be increased in these patients.

[Comparative evaluation of 113 cases with severe and mild forms of extrapulmonary tuberculosis]. / Ciddi ve hafif seyirli 113 akciger disi tüberküloz olgusunun karsilastirmali olarak degerlendirilmesi.

Tuberculosis, one of the oldest diseases of human beings, has still high mortality rates. In this prospective study, 113 HIV seronegative patients with extrapulmonary tuberculosis (EPT) who were admitted to our department between January 2001 and July 2006 have been evaluated and cases with severe or mild forms of EPT have been compared with respect to epidemiological and clinical features, laboratory results and treatment outcomes. The age range of the patients were 16-78 years old (mean age: 46.3 +/- 16.9 years), and 64 of them (56.6%) were female. Severe and mild forms of EPT were diagnosed in 49 (43.3%) and 64 (56.6%) of the patients, respectively. The most frequently involved organ was detected as lymph nodes (43.3%), followed by pleura and vertebrate involvements with the rates of 12.4%. There was an underlying disease in 35 (30.9%) of the patients (diabetes mellitus in 15%; chronic renal dysfunction in 11.5%; malignancy in 4.4%), history of passed tuberculosis infection in 13 (11.5%) and history of contact with a tuberculosis patient in 25 (22.1%). In direct microscopic examination, samples from 19 (16.8) patients were found positive for acid-fast bacilli, and samples cultivated in Lowenstein-Jensen media yielded mycobacterial growth in 25 (22.1%) patients. The diagnosis have been made histopathologically in 89 (78.7%) of the cases. In comparison of the patients with severe and mild forms of EPT, the severe form were detected more frequently in males (p= 0.01), the positivity rates of culture and acid-fast staining were higher in patients with severe form (p= 0.0004 and p= 0.001, respectively). The mortality rate was also found higher in patients with severe form (p= 0.046). The cases who were diagnosed as EPT have been treated by three or four antituberculosis drugs. Izoniazid (300 mg/day, 6-12 months), rifampicin (600 mg/day, 6-12 months), ethambutol (1500 mg/day, 2-4 months), pyrazinamide (2000 mg/day, 2-4 months) and streptomycin (1 g/day, 45-60 days) were used for the therapy. Side effects due to the therapy were observed in 13.3% of the cases (most frequently; gastrointestinal intolerance in 53.3% and hepatitis in 40%), however, there was no necessity to quit the therapy. Surgical treatment has been applied in 14 (12.4%) of the patients. As a result, the investigation of epidemiological and clinical characteristics of extrapulmonary tuberculosis on the large series of cases may be essential for early diagnosis and treatment in endemic countries such as Turkey.

Propylthiouracil-associated eosinophilic pleural effusion: a case report.

We describe an unusual case of a patient with eosinophilic pleural effusion (EPE) associated with long-term propylthiouracil (PTU) administration. A 43-year-old woman was admitted to our hospital after complaining of chest pain. She had had Graves' disease, which had been treated with PTU for 11 years. Right-sided pleural effusion was detected and the result of thoracentesis confirmed an EPE. The patient's detailed medical evaluation failed to reveal any other cause of EPE. PTU was terminated since it was thought to be the cause. Despite withdrawal of the medication, however, the pleural effusion persisted for 6 weeks, and steroid therapy was planned for 15 days in decreasing dosages. During the control visit 10 days after the initiation of steroid therapy, no pleural effusion was observed, and the steroid was discontinued. Rechallenge with PTU produced recurrent pleural effusion. Therapy with PTU was again terminated, and treatment with methimazole and a brief course of low-dose corticosteroids were begun. Chest radiography revealed disappearance of the effusion within 10 days and it did not recur during a 1-year follow-up. To our knowledge, there is only 1 other case in the English-language literature describing EPE caused by PTU. Our report is of particular importance because it describes the development of that disorder in the 11th year of PTU treatment. It also shows that steroid therapy can be effective in treating drug-induced EPE.

Narcolepsy and cataplexy: a pediatric case report.

Narcolepsy is characterized by excessive sleepiness, cataplexy, hypnagogic hallucinations, and sleep paralysis during the rapid eye movement period of sleep. Herein, we present a boy aged eight years who was diagnosed as having narcolepsy and cataplexy about thirteen months after his first presentation. He was admitted with symptoms of daytime sleepiness. In the follow-up, cataplexy in the form of head dropping attacks developed seven months after the first admission. The patient was investigated for different prediagnoses and was eventually diagnosed as having narcolepsy and cataplexy through polysomnography and multiple sleep latency tests thirteen months after the first presentation. He is being followed up and is under drug therapy; his symptoms have improved substantially.

A case of bronchogenic carcinoma presenting with acute abdomen.

Colonic metastasis of the bronchogenic carcinoma is quite rare. Here we document an extremely rare presentation of the lung cancer that presented with acute abdomen and was diagnosed as intestinal obstruction due to colon carcinoma initially. He underwent an urgent operation and the obliterating mass in the colon was resected and reported as "colon metastasis from epidermoid carcinoma probably of the lung". Afterwards bronchoscopy revealed an endobronchial lesion in the right lower lobe that was diagnosed as poorly differentiated squamous cell lung carcinoma. In this case, colon metastasis was diagnosed before the diagnosis of the primary disease.

Clinical, radiologic, and functional evaluation of 304 patients with bronchiectasis.

BACKGROUND: Bronchiectasis continues to be one of the major causes of morbidity and mortality in developing countries, with a probably underestimated higher prevalence than in developed countries. OBJECTIVE: To assess the clinical profile of adult patients with bronchiectasis. METHODS: We retrospectively reviewed the clinical, radiologic, and physiologic findings of 304 patients with bronchiectasis confirmed by high-resolution computed tomography. RESULTS: Mean age of participants (45.7% males, 54.3% females) was 56 ± 25 years and 65.8% of them were lifetime non-smokers. Most common identified causes of bronchiectasis were childhood disease (22.7%), tuberculosis (15.5%), and pneumonia (11.5%). The predominant symptoms were productive cough (83.6%), dyspnea (72%), and hemoptysis (21.1%). The most common findings on chest examination were crackles (71.1%) and rhonchi (28.3%). Types of bronchiectasis were cylindrical in 47%, varicose in 9.9%, cystic in 45.1%, and multiple types in 24.3%. Involvement was multilobar in 75.3% and bilateral in 62.5%. Of 274 patients, 20.8% displayed normal pulmonary function test results, whereas 47.4%, 8% and 23.7% showed obstructive, restrictive, and mixed pattern, respectively. Patients with cystic disease had a higher frequency of hemoptysis (42%) and a greater degree of functional impairment, compared to other types. CONCLUSION: In patients with bronchiectasis from southern Turkey, generally presenting with recurrent productive cough, hemoptysis, dyspnea, and persistent bibasilar rales, the etiology remains mainly idiopathic. Post-infectious bronchial destruction is one of the major identified underlying pathological processes. The clinical picture and the deterioration of the pulmonary function test might be more severe in patients with cystic type bronchiectasis.

Hydatid cysts of the bilateral pulmonary arteries and left ventricle wall: computed tomography and magnetic resonance imaging findings.

Echinococcal cysts located inside the pulmonary artery are extremely rare. The cause is usually rupture of intracardiac cysts or, more rarely, dissemination from a hepatic focus. The case of a 39-year-old patient with multiple hydatid cysts in the right and left pulmonary arteries and left ventricle wall is reported. The patient had undergone surgery for a hepatic hydatid cyst 10 years ago. Multidetector computed tomography angiography and magnetic resonance imaging were performed for the diagnostic evaluation.

Multiple primary chest wall hydatid cysts associated with spinal canal involvement.

Primary multiple chest wall hydatid cysts associated with spinal canal involvement through an intervertebral foramen is an uncommon clinical entity. We present a 54-year-old man who underwent cystotomy and total resection of ribs five through seven via a left posterolateral thoracotomy followed by Th5-Th6 anterolateral partial pediculotomies for removal of cysts in the spinal canal. Although spinal reconstruction was not required, the chest wall defect was repaired with mersilene mesh-methyl methacrylate sandwich graft. Hydatid disease should be considered in the differential diagnosis of mass lesions located in the chest wall. In cases of spinal canal involvement, detailed visualization of spinal canal utilizing MRI and/or CT is essential for planning surgical approach.
