Evaluation of the effects of COVID-19 on pregnancy, fetus and newborn, and treatment management.

Objective: During pregnancy, changes occur in many systems, including the immune system. In line with our experience in the previous years, COVID-19 infections have negative effects on pregnancy. In our study, it was aimed to evaluate the effects of COVID-19 on pregnancy, fetus and newborn, and treatment management. Methods: In our study, 63 patients followed up between April 1, 2020 and April 1, 2021, were evaluated. Demographic data, symptoms, laboratory data, treatments, clinical course and delivery characteristics of the patients, as well as pathologies in the fetus and newborn were investigated retrospectively. The obtained data were statistically analyzed with Statistical Package for the Social Sciences. Results: In this study, 63 pregnant COVID-19 patients aged 19-37 years were included in the study. Fifty of the patients had symptoms of COVID-19 at the time of admission. At the time of admission, 13 patients required oxygen, and ten of these patients had severe radiological involvement. Seven patients were admitted to the intensive care unit, and three of them required invasive mechanical ventilation and deceased afterward. All newborns were found negative for the COVID-19 polymerase chain reaction test. Low birth weight has been detected in eight newborns and low Apgar score in 2 of them. Respiratory distress was observed in four newborns and they were discharged from intensive. Conclusion: Pregnant women have more disadvantages in the course of COVID-19 and have worse maternal outcomes. In addition, treatments such as Lopinavir/Ritonavir and hydroxychloroquine did not have any effect. These patients should be carefully evaluated and followed up.

The Role of CO-RADS Scoring System in the Diagnosis of COVID-19 Infection and its Correlation with Clinical Signs.

BACKGROUND: Computed tomography (CT) evaluation systematics has become necessary to eliminate the difference of opinion among radiologists in evaluating COVID-19 CT findings. INTRODUCTION: The objectives of this study were to evaluate the efficiency of CO-RADS scoring system in our patients with COVID-19 as well as to examine its correlation with clinical and laboratory findings. METHODS: The CO-RADS category of all patients included in the study was determined by a radiologist who did not know the rtRT-PCR test result of the patients, according to the Covid-19 reporting and data system of Mathias Prokop et al. Results: A total of 1338 patients were included. CT findings were positive in 66.3%, with a mean CO-RADS score of 3,4 ± 1,7. 444 (33.1%) of the patients were in the CO-RADS 1-2, 894 (66.9%) were in the CO-RADS 3-5 group. There were positive correlations between CO-RADS score and age, CMI, hypertension, diabetes mellitus, chronic pulmonary diseases presence of symptoms, symptom duration, presence of cough, shortness of breath, malaise, CRP, and LDH, while CORADS score was negatively correlated with lymphocyte count. The results of the ROC analysis suggested that those with age ≥40 years, symptom duration >2 days, CMI score >1 and/or comorbid conditions were more likely to have a CO-RADS score of 3-5. CONCLUSION: The CO-RADS classification system is a CT findings assessment system that can be used to diagnose COVID-19 in patients with symptoms of cough, shortness of breath, myalgia and fatigue for more than two days.

Tocilizumab treatment in severe COVID-19: a multicenter retrospective study with matched controls.

Coronavirus disease-2019 (COVID-19) associated pneumonia may progress into acute respiratory distress syndrome (ARDS). Some patients develop features of macrophage activation syndrome (MAS). Elevated levels of IL-6 were reported to be associated with severe disease, and anti-IL-6R tocilizumab has been shown to be effective in some patients. This retrospective multicenter case-control study aimed to evaluate the efficacy of tocilizumab in hospitalized COVID-19 patients, who received standard of care with or without tocilizumab. Primary outcome was the progression to intubation or death. PSMATCH (SAS) procedure was used to achieve exact propensity score (PS) matching. Data from 1289 patients were collected, and study population was reduced to 1073 based on inclusion-exclusion criteria. The composite outcome was observed more frequently in tocilizumab-users, but there was a significant imbalance between arms in all critical parameters. Primary analyses were carried out in 348 patients (174 in each arm) after exact PS matching according to gender, ferritin, and procalcitonin. Logistic regression models revealed that tocilizumab significantly reduced the intubation or death (OR 0.40, p = 0.0017). When intubation is considered alone, tocilizumab-users had > 60% reduction in odds of intubation. Multiple imputation approach, which increased the size of the matched patients up to 506, provided no significant difference between arms despite a similar trend for intubation alone group. Analysis of this retrospective cohort showed more frequent intubation or death in tocilizumab-users, but PS-matched analyses revealed significant results for supporting tocilizumab use overall in a subset of patients matched according to gender, ferritin and procalcitonin levels.

Comparison of two pandemics: H1N1 and SARS-CoV-2.

OBJECTIVE: We aimed to compare the clinical, epidemiological, and prognostic features of the H1N1 pandemic in 2009 and the severe acute respiratory syndrome coronavirus 2 pandemic in 2020. METHODS: This retrospective study involved subjects from seven centers that were admitted and found to be positive for H1N1 or COVID-19 real-time polymerase chain reaction test. RESULTS: A total of 143 patients with H1N1 and 309 patients with COVID-19 were involved in the study. H1N1 patients were younger than COVID-19 ones. While 58.7% of H1N1 patients were female, 57.9% of COVID-19 patients were male. Complaints of fever, cough, sputum, sore throat, myalgia, weakness, headache, and shortness of breath in H1N1 patients were statistically higher than in COVID-19 ones. The duration of symptoms until H1N1 patients were admitted to the hospital was shorter than that for COVID-19 patients. Leukopenia was more common in COVID-19 patients. C-reactive protein levels were higher in COVID-19 patients, while lactate dehydrogenase levels were higher in H1N1 ones. The mortality rate was also higher in H1N1 cases. CONCLUSIONS: The severe acute respiratory syndrome coronavirus 2 pandemic is a major public health problem that continues to affect the world with its high rate of contagion. In addition, no vaccines or a specific drug for the benefit of millions of people have been found yet. The H1N1 pandemic is an epidemic that affected the whole world about ten years ago and was prevented by the development of vaccines at a short period. Experience in the H1N1 pandemic may be the guide to prevent the COVID-19 pandemic from a worse end.

Real-World Data from Turkey: Is Sofosbuvir/Ledipasvir With or Without Ribavirin Treatment for Chronic Hepatitis C Really Effective?

BACKGROUND: In this study, we aimed to investigate the efficacy and safety of sofosbuvir-based therapies in the treatment of chronic hepatitis C in real-world clinical practice. METHODS: Data from patients with chronic hepatitis C treated with SOF/LDV ± RBV or SOF/RBV in 31 centers across Turkey between April 1, 2017, and August 31, 2018, were recorded in a nationwide database among infectious disease specialists. Demographics, clinical, and virological outcomes were analyzed. RESULTS: A total of 552 patients were included in the study. The mean age of the patients was 51.28 ± 14.2, and 293 (55.8%) were female. The majority had HCV genotype 1b infection (65%), 75.04% of the patients underwent treatment, and non-cirrhosis was present at baseline in 381 patients (72.6%). SOF/LDV ± RBV treatment was given to 477 patients and 48 patients received SOF/RBV according to HCV genotype. The total SVR12 rate was 99% in all patients. Five patients experienced disease relapse during the study and all of them were genotype 2. In patients infected with HCV GT2, SVR12 was 77.3%. SVR was 100% in all patients infected with other HCV genotypes. All treatments were well tolerated by patients without causing severe adverse events. Side effects and side effects-associated treatment discontinuation rates were 28.2% and 0.4%, respectively. Weakness (13.7%) was the common side effect. CONCLUSION: The present real-world data of 525 patients with HCV genotypes 1, 1a, 1b, 3, 4, and 5 who underwent SOF/LDV ± RBV treatment in Turkey demonstrated a high efficacy and safety profile. HCV GT2 patients should be treated with more efficacious treatment.

Evaluation of Diarrhea in Patients with COVID-19.

BACKGROUND/AIMS: The COVID-19 disease, which was declared epidemic by the WHO, is a global emergency public health problem. Patients with extrapulmonary symptoms are the group of patients who should be considered for person-to-person transmission in the community. In our study, it was aimed to investigate the characteristics of patients with COVID-19-related diarrhea symptoms. MATERIALS AND METHODS: The study was conducted retrospectively in CO-VID-19 rtRT-PCR-positive patients in 5 medical centers. Three or more loose/liquid stools per day or increased number of defecations compared to normal defecation were defined as diarrhea. The patients were analyzed in 2 groups as those with and without diarrhea. RESULTS: One thousand eighty-six patients were included in the study. Seventy-eight (7.2%) of the patients had diarrhea. Diarrhea was watery in 54 (69.2%) patients while with blood and mucus in 18 (23.1%) patients. Diarrhea continued for an average of 5.2 ± 1.6 (2-11) days. The clinical and laboratory findings of patients with diarrhea were more serious than those without diarrhea. Diarrhea is more common in the elderly and people with comorbid disease, and patients with diarrhea had higher CMI score and CRP and higher complaints of fever, cough, shortness of breath, myalgia, and fatigue. CONCLUSIONS: The presence of diarrhea should indicate a suspected COVID-19 infection and suggest testing for early diagnosis of the disease. It should be kept in mind that the course of the disease may be more severe in these patients, and precautions should also be taken in terms of fecal transmission during discharge.

Treatment of partial-thickness burns with a tulle-gras dressing and a hydrophilic polyurethane membrane: a comparative study.

OBJECTIVE: The purpose of this revisited study was to compare the clinical efficacy and long-term scar evaluation of a hydrophilic polyurethane membrane (HPM), Omiderm (Omikron Scientific Ltd., Rehovot, Israel) and an antimicrobial tulle-gras dressing (TGD), Bactigras (Smith & Nephew) in the management of partial-thickness burns. METHOD: Patients with partial-thickness burns were enrolled in this prospective study. Burn areas were divided into two areas and both dressings were applied to each field at the same time. Time to full re-epithelialisation and scar evaluation were compared using the Vancouver Scar Scale (VSS). RESULTS: A total of 21 patients, mean age 36.8 years, with 22 burns areas participated. The results showed that there is no statistically significant difference in terms of full epithelialisation time in the application of either dressing (p>0.05). However, with deep dermal burns, the HPM provided slightly faster epithelialisation (p>0.05). A VSS assessment showed no statistically significant difference (p>0.05) between applying either dressing materials. CONCLUSION: This study indicated that both dressings had the same effectiveness in treatment of partial-thickness burn wounds. However, the use of the HPM, especially in deep dermal second-degree burns, should be one of the first-line clinical choices, based on the advantages discerned by this study.

Comparison of Neurosensory Assessment Methods in Plastic Surgery.

Sensory assessment of the skin is essential to document the function of the sensory fibers of the tested nerves. The Semmes-Weinstein monofilaments, disk-criminator, electrodiagnostic testing, and Pressure-Specified Sensory Device (PSSD) have been currently used to assess sensory function of peripheral nerves. None of these methods is optimal because of different drawbacks; however, an increasing number of articles, which recognize the reliability of PSSD, have been published during the last decade. In this review, following a short overview on basic physiology and assessment methods of the skin sensory receptors, we compared the sensory assessment methods and summarized the applications of the PSSD in the field of different clinical areas, mainly peripheral neuropathies, breast, and flap surgery.

Fetal Cleft Lip/Palate Surgery: End of a Dream?

Recognition that a fetus can scarlessly heal in intrauterine life led to various animal studies in the mid 1980s exploring the possibility of fetal cleft lip/palate surgery. The idea of scarless cleft repair seemed like a possible dream after the promising results from the early animal studies. In this review, we analyze the progress made in the 30 years since our first experience with animal models.

Effect of Allogeneic Platelet Lysate and Cyanoacrylate Tissue Glue on the Fibrovascularization of the Porous Polyethylene Implant.

Because of limited autogenous tissue sources, donor site morbidity, and difficulty of shaping the autologous tissue, surgeons often need to use alloplastic frameworks in reconstruction of 3-dimensional tissue defects. Synthetic porous polyethylene (PP) implant is widely used in plastic surgery for 3-dimensional reconstruction of the lost or highly deformed tissues. One of the main factors of PP implant exposure is delayed fibrovascular ingrowth. In the present study, the authors investigated the effect allogeneic plateletlysate (PL) and cyanoacrylate tissue glue (CTG) (2-octyl cyanoacrylate) on the fibrovascularization of the PP implant.Twenty adult female Wistar rats were divided into 4 groups equally, according to the different surgical techniques and implanted materials used. Only PP implant was implanted subcutaneously through a skin incision on the chest wall skin of the rats in the control group; however, CTG was applied with PP implant in the cyanoacrylate group, PL was applied with PP implant in the platelet group, CTG and platelet was applied together with PP implant in the combination group. All of the implants in each group were histologically assessed at postoperative second week. Determination of the collagen density in the tissues, inflammation, and necrosis and vascularization status was assessed semiquantitatively.A denser collagen structure, low inflammation, and necrosis were found in PL groups. There was, however, a significant decrease in vascular density with PL-treated groups. PL treatment may have a potential to reduce complications related to PP implants.

The Future of Plastic Surgery: Surgeon's Perspective.

Since the days of Sushruta, innovation has shaped the history of plastic surgery. Plastic surgeons have always been known as innovators or close followers of innovations. With this descriptive international survey study, the authors aimed to evaluate the future of plastic surgeons by analyzing how plastic surgery and plastic surgeons will be affected by new trends in medicine. Aesthetic surgery is the main subclass of plastic surgery thought to be the one that will change the most in the future. Stem cell therapy is considered by plastic surgeons to be the most likely "game changer." Along with changes in surgery, plastic surgeons also expect changes in plastic surgery education. The most approved assumption for the future of plastic surgery is, "The number of cosmetic nonsurgical procedures will increase in the future." If surgeons want to have better outcomes in their practice, they must at least be open minded for innovations if they do not become innovators themselves. Besides the individual effort of each surgeon, international and local plastic surgery associations should develop new strategies to adopt these innovations in surgical practice and education.

Anatomy of the Anterior Deep Temporal Nerve: Implications for Neurotization in Blinking Restoration in Facial Paralysis.

Facial paralysis can lead to dysfunctions in eyelid closure, which is called lagophthalmos. A number of surgical procedures, both dynamic and static, have been described to restore the innervation of the orbicularis oculi muscle that closes the eyelids. This cadaver-based anatomical study aimed to evaluate the anatomy of the anterior, middle, and posterior deep temporal nerves; nerves to the temporalis muscle; and their availability for direct muscle neurotization of the orbicularis oculi. A total of 10 hemisectioned head specimens from 5 adult cadavers (2 men and 3 women) were used in this study. The adequacy of the length of the anterior deep temporal nerve was assessed for direct neorotization of the orbicularis oculi muscle. The mean distances between the originating point of the deep temporal nerves from the mandibular nerve in the infratemporal fossa and their terminal entry points into the muscle were 46.4 (42-51 mm), 42.2 (38-46 mm), and 33.4 mm (26-40 mm) for the anterior, middle and posterior branches of the nerves, respectively. We conclude that the anterior deep temporal nerve is a versatile nerve that can be used for direct muscle neurotization, nerve transfer, and babysitter procedures in selective blinking restoration. Before proceeding with any further clinical use, an anatomical study should be performed with fresh specimens from cadavers.

Severe Sunburn After a Hot Air Balloon Ride: A Case Report and Literature Review.

Hot air balloon tours are very popular among travelers worldwide. Preventable burn injuries associated with hot air balloon rides have been reported during crashes into power lines, in propane burner explosions, and following contact with the propane burner tanks. We present a case of severe repeated sunburn, which poses another risk of preventable injury during hot air balloon rides, and briefly discuss the injury epidemiology of hot air balloon rides.

Experimental stem cell therapies on burn wound: do source, dose, timing and method matter?

Stem cell therapy has been introduced as a new and promising modality of wound covering in recent decade. It has been used for improvement of burn wound, post burn scar and saving stasis zone of burn with good results. However, there have been some differences between the various experimental burn wound trials in stem cell source, therapeutic dose, delivery method and timing of stem cell delivery. In our study, we aimed to review stem cell biology and investigate discrepancies in animal trials of use of stem cells in burn wound account for the variation in, stem cell source, therapeutic dose, delivery method and timing of stem cell delivery.
