Emergencies in dental surgery during the COVID-19 pandemic

Introduction: Patients' negligence and difficult access to healthcare have an impact on the worsening of emergency conditions, which require immediate treatment due to the possibility of exacerbation in a short period of time. Untreated intra- and extraoral abscesses can have serious consequences on the patient's health and in many cases are life-threatening conditions increasing risk of respiratory obstruction, thrombophlebitis, meningitis, mediastinitis and septicemia. Background: The aim of this study is to investigate the impact of the pandemic and the resulting impediments to accessing medical care on the incidence and type of emergencies in the Oral Surgery Department. Material and methods: This was a retrospective study of 85375 patients aged 2 months to 90 years old with diagnosed intra- and extraoral abscesses before COVID-19 pandemic (2018,2019), and during pandemic (2020, 2021) in the Department of Oral Surgery of the Medical University in Lublin. The obtained results were statistically analyzed with the use of a computer program. Conclusions: The fewest patients were admitted in 2020, and the most in 2021, where we can already see the effects of the pandemic. Emergencies occurred most frequently in people aged 21-30, then 31-40. In 365 cases, tooth extraction was performed, and only in 28 cases, root canal treatment was attempted. Conclusions. Oral health service provision has been significantly affected by COVID-19. Patients came to their appointments too late, which in most cases resulted in the necessity of tooth extraction without attempting root canal treatment.

Management and care of pregnant women in their third trimester with COVID-19 at Tangerang Hospital, Indonesia: a comprehensive approach

COVID-19 is a widespread contagious viral infection that can severely affect the respiratory system. Although many people recover from using the disease without special care or treatment, pregnant women are particularly vulnerable to pulmonary infections due to their hangers systems system and physiology. To investigate the treatment provided to pregnant women who are PCR-positive for COVID-19 in their early three months of pregnancy, a reanalyzed analyzed data from 84 participants who received treatment at Tangerang Regional Hospital in 2 study was the study conducted based on an ases of observational investigation with a cross-sectional approach. It assembled the data for analysis of the chi-square test. The results showed that 92.9% of participants underwent a cesarean section, while the remaining 7.1% were discharged after giving birth typically or recovering. Additionally, the study did not find any correlation between factors such as age, education, work, gravida, ANC visit, and the impact of COVID-19 on the third trimester of pregnancy at Tangerang Hospital in 2022. The study recommends that pregnant women seek information about pregnancy care from healthcare providers, particularly midwives, posyandu officers, and the media, to make well-known decisions about their health and well-being during this critical period, ensuring a safe and healthy pregnancy outcome.

A comprehensive overview on COVID-associated mucormycosis

In recent times, numerous reports of systemic fungal infections have been a major concern. The angioinvasive fungal infection, mucormycosis has surged in patients with COVID-19 due to various factors, mainly uncontrolled diabetes and inappropriate corticosteroid use. The prevalence of this acute and fatal fungal infection caused by Mucorales-related fungal species has been highest in the Indian population. COVID-associated mucormycosis (CAM) has a propensity for contiguous spread, and exhibits high morbidity as well as mortality. Unless promptly detected and treated, it is associated with a poor prognosis. A high index of suspicion, aggressive surgical debridement and use of systemic antifungal agents continue to be the standard of care for CAM. Moreover, there is an imperative need to address this public health issue by increasing public awareness and education. This article provides a comprehensive overview on the emergence of CAM during the pandemic, the current burden, pathophysiology, diagnostic interventions and management of CAM in Indian clinical practice.

Vitamin-D deficiency, the hidden pandemic in sunshine sufficient countries, exacerbating hypocalcaemia in a health worker undergoing thyroidectomy - a global perspective and review of literature

Introduction: Vitamin D deficiency (VDD) is common in young adults even in sunlight sufficient countries. It manifests with subtle and trivial symptoms that are often ignored. Nutritional deficiency due to improper dietary habits, poverty, long hours at work and study are factors. The lockdown during COVID has exacerbated the incidence. We had a patient with VDD who became symptomatic after routine thyroidectomy prompting our review into literature on the global health perspective of VDD. Material and method: - A 21-year-old nursing student developed hypocalcaemia within 24 hours after a routine thyroidectomy. VDD was detected and patient improved after supplementation. Literature was reviewed from Pubmed database for the medical aspects of the problem, from Government archives like the Scientific Advisory Committee on Nutrition, ICMR etc for cause and medical archives including those of paediatric and general health for the impact of disease at the state, national and global level. A global health problem list was prepared and data was reviewed. Discussion: Vitamin D is protective against respiratory infections due to viral aetiology including COVID. However, complete lockdown to prevent spread of COVID, online learning, and work from home culture has reduced sunlight exposure and increased incidence of VDD. Post thyroidectomy hypocalcaemia is common in VDD. Conclusion: Since there is a high prevalence of asymptomatic VDD even in sunshine sufficient countries, it is recommended to screen all patients especially young adults for VDD during routine preoperative work up.

Comparative study of feto-maternal outcome of ante-natal cases as per the standard WHO guidelines vs revised antenatal visit schedule during COVID19 pandemic

Background: Good antenatal care helps a woman face labour in good health and optimum conditions. The National Institute for Health and Care Excellence (NICE) and WHO guidelines suggest 15 visits in the whole pregnancy. Keeping in view the COVID-19 pandemic to reduce the exposure of pregnant ladies the number of antenatal visits was reduced to 7 milestone visits and outcome was noted. This study aimed to do a comparative study of feto-maternal outcome in antenatal cases at our centre using standard WHO protocol vs. revised antenatal protocol during COVID-19 pandemic. Subjects and Method: This was an observational study done at a tertiary care center of an Armed forces hospital with target population as pregnant ladies attending antenatal care Out patient department of the hospital during COVID19 pandemic Vs Antenatal cases in previous 1 year. A comparative analysis of pregnancy outcome, maternal variables during pregnancy and delivery along with neonatal variables was done. Results: There were lesser deliveries by 41.7% as compared to non-COVID times. There was an increase in the caesarean delivery rate and instrumental delivery rate during COVID times by 11% and 53% respectively. There was increase in Vaginal birth after caesarean (VBAC) by 26.6%. The incidence of fetal growth restriction, placental abruption, maternal anaemia and gestational diabetes mellitus, oligohydramnios and polyhydramnios was low. The incidence of spontaneous abortions was also low in our study. In contrast, the incidence of pre-term deliveries doubled from 7.4% to 13.4%. Neonatal morbidity and mortality indicators like Neonatal Intensive care unit (NICU) admissions showed a rising trend of 1.7% during the COVID (14.6% to 16.3%) with a minimal rise in early neonatal deaths by 0.2%. Conclusion: Our model doesn't show an increase in maternal, neonatal morbidity, and mortality. This model can be used as a standard of care for Antenatal patients during Pandemics. It reduces the risk exposure of the gravid mother without any significant increase in maternal and neonatal morbidity and mortality.

Identification of obstetric risks in COVID-19 times in a community health area, Ecuador

Introduction: risk factors associated with complications in the mother-child pair include: history of hypertensive disorders, adolescent pregnancy, drug use, unfavorable obstetric history with a background of miscarriages or abortions, sexually transmitted diseases and urinary tract infections. Background: to identify the obstetric risk in times of COVID-19 pandemic at the "Bastion Popular" health area, Guayaquil, Ecuador, from January to June 2021. Method: a descriptive-transversal field research was carried out, with a quantitative approach, which favored the analysis of the obstetric risk categories recorded in the medical history of 117 pregnant women, who signed an informed consent, for the collection of data through home visits, using the obstetric risk scale or score. Results: outcomes assessment showed, as main result, that the most frequent obstetric risk group was the age group 20 to 24 and the high risk factor was the main category identified. Obstetric risk increased proportionally when the interpregnancy interval was reduce. Conclusions: young women between 20 and 24 years of age are those who presented the highest obstetric risk, which is correlate with a higher number of gestations, abortions, deliveries and cesarean sections. Therefore, it is necessary to provide women with information about pregnancy and its complications, so that they are able to identify risk factors during pregnancy, delivery and the puerperium.

Maxillofacial emergency's care during the COVID-19 pandemic, Granma 2021

Introduction: during the COVID-19 pandemic, new safety measures were implemented in all sectors. However, the Maxillofacial Surgery specialty kept on, where emergency patients were not left unattended. Background: to characterize the maxillofacial emergencies attended at the Hospital Clinico Quirurgico Docente "Celia Sanchez Manduley" in Manzanillo, during the COVID-19 related epidemiological situation. Methods: an observational, descriptive, and cross-sectional study was applied on 358 patients in the period between September 2020 and April 2021. The variables studied were as follow: age groups, sex, month when patients were attended, maxillofacial emergency's motive, therapeutic behavior and patients with COVID-19 related symptoms. Results: the most affected age group was 60 (22.6%), with predominance in male sex (54.2%). Most patients were attended in November and December (20.3%), the predominated maxillofacial emergencies were those associated to maxillofacial trauma (31.8%), followed by facial cellulitis (23.7%). In terms of treatment, the highest percentage of conservative treatment was associated with the medicamentation (88.3%), while wound suturing practice predominated in surgical treatment (18.2%). The symptom with the highest incidence was fever (3.4%). The 61.5% of the maxillofacial surgeons were infected with COVID-19. Conclusions: maxillofacial emergencies are more frequent in males;maxillofacial trauma and facial cellulitis predominate. The maxillofacial surgery service is vulnerable to the coronavirus infection.

Challenges faced by anesthesiologists during the cesarean section of COVID-19 patients - an observational study

Background: The health-care system has encountered exceptional circumstances, experiencing unique challenges, and manifesting as acute challenges in health-care services due to the spread of COVID-19. Aims and Objectives: The present study aimed to report the difficulties faced by the anesthetists while performing a cesarean section under the subarachnoid block (SAB) in COVID-19 patients at a dedicated COVID Level 3 hospital. Materials and Methods: Twenty healthy anesthetists (six consultants and 14 postgraduate) aged 20-40 years performed 60 elective or emergency cesarean sections of known COVID-19-positive gravida patients aged 20-35 years with no comorbidity and no spine abnormality under the SAB. Anesthetist;s responses to the challenges faced while performing procedures wearing the Level 3 personal protective equipment were recorded using a pre-structure self-administered questionnaire. To quantify the intensity of these problems, all the physical and psychological difficulties were graded as mild, moderate, and severe. Results: In the present study, 75% experienced moderate-to-severe sweating, and 60% experienced moderate-to-severe headaches. A total of 45% experienced moderate-to-severe breathlessness. Though there was little difficulty in communication among doctors and staff, almost 75% of anesthetists faced it. The fear of contracting the disease and spreading it to the family members was expressed by 75-80% of anesthetists. Conclusion: The present scenario has increased physical stress and other psychological problems among health workers. Therefore, hospital support with regular psychological counseling sessions is needed for healthcare workers to cope with the current situation.

Post-cardiac surgery outcomes following COVID-19 infection in unvaccinated patients

The provision of cardiac surgery services nationwide has been affected by the COVID-19 pandemic. We noticed a high COVID-19 mortality rate in unvaccinated patients who were diagnosed with COVID-19 after recent cardiac surgery. All the patients were tested negative for COVID-19 before surgery. We conducted a review of our hospital data and reported our findings. We identified 15 patients and reported 7 deaths (46.7%). All the patients died from COVID-19 or its complications. We recommend that cardiac centres actively promote vaccination before cardiac surgery and also enhance infection control measures to prevent nosocomial infections.

Reduced pain intensity at the first dressing improves postoperative pain control after anorectal surgery

This study aimed to investigate the effects of first dressing changes on the postoperative pain intensity and the duration of pain in patients after anorectal surgeries to provide evidence for improving postoperative pain control. A total of 164 patients with an anorectal disease scheduled to undergo surgery were enrolled in this study, and their postoperative pain levels and duration were recorded. The status of severe pain for a rating score 7 during hospitalization after surgery was considered as the study endpoint. The pain score at the first dressing change was recorded and considered a potential risk factor for predicting severe pain during hospitalization by logistic regression analysis. Comparisons of postoperative pain outcomes between patients with a pain rating score 7 or <7 were performed before and after propensity score matching. Severe pain (rating score 7) at the first dressing change was an independent risk factor for severe pain during hospitalization (odds ratio (OR) = 8.33, p < 0.001). Pain on the first night after surgery in the Severe group was higher than in the Non-Severe group (3.2 +or- 0.9 vs. 2.8 +or- 1.0, p = 0.006). Patients in the Severe group had higher pain number rating scale (NRS) scores at the second (5.2 +or- 1.3 vs. 3.1 +or- 1.2, p < 0.001) and third (3.5 +or- 1.5 vs. 1.9 +or- 0.9, p < 0.001) dressing change than those in the Non-Severe group. Moreover, the overall NRS pain score during hospitalization in the Severe group was significantly higher than the Non-Severe group (5.7 +or- 1.1 vs. 3.9 +or- 1.5, p < 0.001), and the incidence of severe postoperative pain during hospitalization was also higher (61.6% vs. 12.1%, p < 0.001). In addition, pain duration in the Severe group was significantly longer than in the Non-Severe group (10 (3, 18) vs. 5 (2, 10), p < 0.001). Regarding the distributions of propensity scores, the overall NRS pain score during hospitalization in the Severe group was significantly higher than in the Non-Severe group (5.7 +or- 1.1 vs. 3.8 +or- 1.4, p < 0.001), as well as a higher incidence in severe postoperative pain (61.2% vs. 7.5%, p < 0.001), which was accompanied by a significantly longer pain duration in the Severe group (10 (3, 18) vs. 5 (2, 10), p < 0.001). Moreover, subgroup analysis showed that patients in the Severe group had higher overall pain NRS scores than the Non-Severe group for both the Milligan-Morgan (5.6 +or- 1.5 vs. 4.0 +or- 1.1, p < 0.001) and Thread-ligating (5.8 +or- 1.4 vs. 3.9 +or- 1.0, p < 0.001) surgery groups. Pain intensity at the first dressing change was sociated with the intensity and duration of postoperative pain in patients who underwent anorectal surgery. Thus, proper actions are needed to relieve the pain intensity at the first dressing change.

Differences in interleukin-6 and interleukin-17 expression in COVID-19 post-mortem lung tissue biopsy compared with noncovid- 19

Background: COVID-19 has spread rapidly around the world. It is necessary to study lung tissue of postmortem COVID19 patients to determine the molecular alteration particularly the role of IL-6 and IL-17 in causing fatality. Background: This study aims to determine the differences in the expressions of IL-6 and IL-17 in lung tissue of post-mortem COVID-19 patients compared to non-COVID-19 patients. This study also aimed to analyze the correlation between the expressions of IL-6 and IL-17 in lung tissue of post-mortem COVID-19 patients. Methods: This research is an observational analytic study with crosssectional approach. The samples were 15 paraffin blocks of post-mortem lung tissue biopsy of COVID-19 patients, and 15 paraffin blocks of inflammatory lung tissue biopsy or surgery of non-COVID-19 patients. IL-6 and IL-17 expressions were evaluated by immunohistochemical procedure. Result: There was a significant difference in the expression of IL-6 in the COVID-19 group and the non-COVID-19 group with a p-value = 0.001 (p < 0.05). There was a significant difference in the expression of IL-17 in the COVID-19 group and the non-COVID-19 group with p-value = 0.001 (p < 0.05). There was a significant correlation between the expressions of IL-6 and IL-17 in the COVID-19 group, with the Spearman coefficient value (rs) of 0.548 with p = 0.034 (p < 0.05). Conclusion: There are differences in the expression of IL-6 and IL-17 between COVID-19 and non-COVID-19 lung tissue. There is a significant correlation between the expressions of IL-6 and IL-17 in post-mortem lung tissue of COVID-19 patients.

Ethical issues in surgery during COVID-19 pandemic

Surgeons were facing considerable ethical dilemma during this COVID-19 pandemic-whichpatient to select for surgery and which patient to be deferred for a later date. Surgeons also had a difficult taskof protecting themselves and their team and perform a safe surgery without infecting the patient. There were also ethical issues of using Oxygen or an Intensive Care Unit (ICU) bed during this time for the surgical patient when it was in short supply. A critical factorwas balancing the benefit of surgery for the patient against the risk of contacting the COVID-19 virus and the complications of the disease process.

A role of black fungus in COVID-19: a review

Mucormycosis is a rare type of fungal infection commonly known as zygomycosis, the infection tends to crop up more commonly in individuals with low and weakened immunity level, if left untreated, the mucormycosis can be life-threatening and fatal. Mucormycosis previously known as zygomycosis is a consequential type of infection caused by several mildews known as micromycetes. The revised taxonomical studies revealed that the micromycetes causing the infections are classified as the species of phylum Glomeromycota, class Glomeromycetes, subphylum Mucoromycotina, order Mucorales. The genera of Rhizopus, Mucor, Lichtheimia, Cunninghamella, Rhizomucor, and Apophysomyces, constitute the causative agents of the majority of cases of mucormycosis. The angioinvasive type of disorder caused by mucormycosis is further classified as Mucorales. The patients with Diabetes ketoacidosis and diabetes mellitus are at high-risk factors, followed by the patients with organ transplant, immunocompromised disease, and malignancy. The route of exposure to Mucormycosis may be through the wounded infection that can be pneumonic, or dermal in origin. In the ectodermal form, the fungal organism can invade the skin through open or puncture wounds, or the laceration on the skin. However, the infection has a high mortality rate, the key to successful treatment is early diagnosis, and administration of antifungal drugs, with extensive therapy, followed by surgical debridement of the infection. The morbidity and mortality rate are still at a high number, due to the negligence of the patient to seek medical treatment. Hence the early diagnosis and treatment with antifungal drugs with surgical debridement is a must. The efficacy of oral and venous formulations in the treatment of mucorales is still under debate. Despite the aggressive therapy, the mortality rate is increasing worldwide. The studies have to be conducted to invent the fastest treatment protocol for the treatment of Mucormycosis.

Investigation of long-term follow-up results of COVID-19 disease in kidney transplant patients and the effect of inactive COVID-19 vaccine

Objective: We aimed to evaluate the long-term graft functions of kidney transplant recepients (KTR) who have been cured of the COVID-19 and to investigate the role of inactivated COVID-19 vaccine in the clinical course of the disease. Materials and Methods: KTR who had COVID-19 pneumonia between March 2020 and September 2021 were included in the study.. The clinical course of the disease was evaluated in vaccinated patients and compared with those who were not vaccinated. The laboratory information of the patients at the time of admission to the hospital, 6 months and 12 months after the disease was recorded. Results: Of the 83 patients included, 67.5% were male. COVID-19 disease developed in 20 patients after vaccination. Vaccine;it decreased the development of acute kidney injury (AKI) 5.9 fold and hospitalization in the intensive care unit (ICU) 1.4 times fold (p < 0.05). In the follow-up, 10 patients died at the first admission to the hospital and no late death was recorded in the first year. Dialysis treatment was started in 5 patients due to graft loss. Conclusion: In kidney transplant patients, graft dysfunction may develop after COVID-19 infection. However, the inactivated COVID-19 vaccine;it can reduce the risks of hospitalization, AKI, and ICU admission.

Rhino-orbital mucormycosis after COVID-19 in the emergency department

Rhino-orbital mucormycosis (ROM) is an acute and fulminant infection. The number of ROM cases developing after coronavirus disease 2019 (COVID-19) is increasing. A 62-year-old male patient was admitted to the emergency department in northern Syria complaining of new-onset vision loss, swelling, and severe swelling of the left eye. It was noted that a 3-day course of prednisolone 250 mg was given to treat COVID-19. We found that he had a history of diabetes mellitus (DM) for 10 years. Physical examination revealed ptosis, proptosis, and ocular movement restriction in all directions in the left eye. All other systemic examinations were normal. A cranial and orbital magnetic resonance imaging scan performed after hospitalization for further evaluation and treatment showed an increase in the density of the sphenoid, ethmoid, and frontal sinus walls in the left orbit. Despite antifungal and surgical treatment, the patient died on day 14. The use of steroids in treatment and the presence of concomitant DM are the main predisposing factors. The prognosis of this disease, which has a high mortality and morbidity, is adversely affected in geographic regions where health care is inadequate.

Use of stem cell therapy in COVID-19

Severe acute respiratory syndrome coronavirus 2 is known to cause the new coronavirus disease 2019 (COVID-19), in which many organs and systems such as the lung, heart, and immune system can be severely affected. Currently, the treatment process is generally based on supportive and palliative care. Some potential drugs are being tested for treatment. At this point, perhaps a promising treatment method for many diseases in the future seems to be stem cell therapy in recent times. Stem cell therapy in COVID-19 may be a treatment method that can play an important role, especially in resistant and severe cases. In this review, we summarized the potential mechanisms of stem cell therapy and developments in this treatment modality.

Brachycephalic obstructive airway syndrome: an overview

One of the conformational issues by the explosion Of pet ownership throughout the COVID 19 pandemic is the Ming number dunes of brachycephalic obstructive envay syndrome (BOAS), which is a condition prevalent in some of the UK's most copular dog breeds The challenges the veterinary profession is not only to identify and treat affected individuals from within the population of dogs presenting to primary care clinicians, using surgical and non-surgical options but also to educate clients on how to recognise clinical signs of the disease as early as possible.

A current and common cause of secondary spontaneous pneumothorax: COVID- 19 pneumonia

This study evaluated cases of spontaneous pneumothorax developing secondary to SARS-CoV-2 pneumonia. Sixteen cases presenting to our hospital due to spontaneous pneumothorax developing secondary to SARS-CoV-2 pneumonia between March 2020 and February 2020 were evaluated retrospectively. Ten patients (62.5%) were men, and six (37.5%) were women, with a mean age of 68 .. 20.3 years (range 18 - 90 years). Pneumothorax was in the right hemithorax in 11 cases (68.75%), in the left hemithorax in two (12.5%), and bilateral in three (17.75%). Pneumothorax developed during active SARS-CoV-2 pneumonia in all 16 cases (100%). No pneumothorax was detected following the healing of SARS-CoV-2 infection. Pneumothorax was observed while patients were not intubated in 15 cases (93.75%), but pneumothorax developed during mechanical ventilation in one case (6.25%). Tube thoracostomy was performed on all patients in treatment. Air leakage from the tube was observed in 14 cases (87.5%). The mean duration of tube thoracostomy was 18.3 .. 20.1 days (range 1 - 81 days). Pneumothorax resolved after treatment in seven cases (43.75%), while mortality occurred in nine (56.25%). Pneumothorax recurred after treatment in one case (6.25%). Pneumothorax is widely seen in the active period or after healing in cases infected with COVID-19. Aggressive treatment is generally required for this clinical manifestation with high mortality.
