Impact of covid-19 pandemic on characteristics of dental emergencies and treatment services at tertiary care centre

PurposeTo categorize and compare the dental emergencies along with status of health services received in the tertiary dental health care centre during the pre covid- 19 periods and period of the complete lockdown in COVID 19 pandemic. Methods: A retrospective cross-sectional observational survey was conducted. Four different groups period were studied on patients who visited for dental emergencies at tertiary care centre. April 14 to 13 May 2020 assigned and analyzed as a test period group or group IV. The control period group i.e. group III was 14 February 2020 to 17 March, pre lockdown COVID 19 month when there was no consideration of epidemic in India. Same as periods of group II and IV, group I and II from last year 2019 were also assigned and analyzed. The tertiary care centre provision of health services during this pandemic was also inquired and evaluated. The information was recorded regarding availability of health services like non-emergency dental treatments, emergency dental services, and online professional consultation. To compare four different time period of obtained data, Analysis of variance (ANOVA) and Chi square test were used. Results: The overall proportion and percentage of dental emergencies were raised. The reason for emergency visits to dental clinic were the main problem related with pulpal (46.0%) followed by abscess (16.6%), periapical lesions (15.0%), cellulitis (4.1%) or trauma (0.3%). In lockdown most of the dental emergencies 228(2 6 5) were endodontic related (86.1%) which managed mostly through ‘3A” approach (advise, analgesics and antibiotics) (60.1%) and remaining (26.0%) through extraction.     

Endovascular Therapy for Ischemic Stroke

The utility of intravenous tissue plasminogen activator (IV t-PA) in improving the clinical outcomes after acute ischemic stroke has been well demonstrated in past clinical trials. Though multiple initial small series of endovascular stroke therapy had shown good outcomes as compared to IV t-PA, a similar beneficial effect had not been translated in multiple randomized clinical trials of endovascular stroke therapy. Over the same time, there have been parallel advances in imaging technology and better understanding and utility of the imaging in therapy of acute stroke. In this review, we will discuss the evolution of endovascular stroke therapy followed by a discussion of the key factors that have to be considered during endovascular stroke therapy and directions for future endovascular stroke trials.     

Control of hospital acquired infections in the ICU: A?service perspective

Background

The service setting has some unique strengths and weaknesses that must be kept in mind when organizing Hospital acquired infections (HAI) prevention interventions.

Methods

Following an initial study to gather data regarding HAI in the Surgical intensive care unit (ICU) we put into place various infection control interventions. The present study was carried out to analyse the effect of these interventions on the incidence of HAI in the ICU.

Results

The total admissions to the ICU were 253 patients. Eighty eight patients (34.78%) were admitted for more than 48 hr, 165 patients stayed for less than 48 h. The frequency of HAI was 7.95% (95% CI 3.54, 15). Hospital acquired pneumonia was observed in 2 of the 88 patients (2.27%) (95% CI 0.38, 7.30) which amounted to 9.70 infections per 1000 ventilator days. Bloodstream infection was detected in 3 out of 88 patients (3.4%) (95% CI 0.87, 8.99) amounting to 6.54 fresh infections per 1000 Central Venous Catheter days. Urinary tract infection was observed in 2 (2.27%) (95% CI 0.38, 7.30) at 2.86 fresh infections per 1000 catheter days. As compared to the previous study we found that there was a decline of HAI ranging from 60 to 70%.

Conclusion

Our study demonstrated that by meticulously following infection control protocols especially tailored to the service setting the incidence of HAI''s can be reduced. However, the challenge is in maintaining the gains achieved since there is a rapid turnover of manpower in the ICU and a lack of a structured ICU design model.     

Juvenile ossifying fibroma diagnosed on fine needle aspiration cytology: A diagnostic challenge

Preoperative diagnosis of jaw lesions is not always possible on the basis of clinico‐radiological findings alone and needs to be confirmed before attempting any surgical intervention. Fibro‐osseous lesions of the jaw comprise a spectrum of diseases which include cement‐osseous dysplasia, fibrous dysplasia, and ossifying fibroma. The cytomorphological distinction between these individual entities is difficult. We present a case of maxillary fibro‐osseous lesion in an adolescent girl diagnosed and categorized as juvenile ossifying fibroma preoperatively on cytology and confirmed on histopathology. Although aspirates are usually paucicellular in fibro‐osseous lesions, certain cytological features if present in cellular cytosmears can offer further categorization and a definitive diagnosis may be possible in light of clinico‐radiological correlation.

Cardiometabolic Impact of Non-Statin Lipid Lowering Therapies

There is evidence from epidemiology, pathophysiology, and clinical trials that high LDL cholesterol levels cause atherosclerotic heart disease. Current guidelines recommend an LDL cholesterol target of 70 mg/dL for patients at high or very high risk. The risk imposed by LDL cholesterol is modulated by the presence of additional risk factors such as age, smoking, and indices of inflammation. Epidemiologic studies as well as rare congenital conditions (e.g., hypobetalipoproteinemia) have shown that very low LDL cholesterol (lower than 70 mg/dL) levels are associated with a very low risk of cardiovascular disease. Analyses of randomized clinical trials have shown a greater benefit in reducing the risk of cardiovascular disease (without an increase in adverse events) among those with very low achieved LDL (below 40 mg/dL). In one study of patients with achieved LDL cholesterol below 30 mg/dL, there was no increase in the usual adverse events compared to patients with LDL cholesterol levels above 30 mg/dL. High-intensity statin therapy is associated with a higher rate of transaminase elevations, but no hepatic failure, a very small risk of myopathy, and an increased risk of developing diabetes. However, the small increase in the risk of developing diabetes is much smaller than the marked lowering of cardiovascular risk. The duration of statin therapy may be important in studies of primary prevention and early, probably low-dose statin therapy, may achieve primordial prevention of atherosclerotic disease.     

Is liquid heparin comparable to dry balanced heparin for blood gas sampling in intensive care unit?

Introduction:

Blood gas (BG) analysis is required for management of critically ill patients in emergency and intensive care units. BG parameters can be affected by the type of heparin formulations used-liquid heparin (LH) or dry balanced heparin (DBH). This study was conducted to determine whether blood gas, electrolyte, and metabolite estimations performed by using DBH and LH are comparable.

Materials and Methods:

A prospective study was conducted at pediatric intensive care unit (PICU) of a tertiary care hospital. Paired venous samples were collected from 35 consecutive children in commercially prepared DBH syringes and custom-prepared LH syringes. Samples were immediately analyzed by blood gas analyzer and compared for pH, pCO₂, pO₂, HCO₃⁻, Na⁺, K⁺, Cl^-, and lactate. Paired comparisons were done and agreement was assessed by Bland-Altman difference plots. The 95% limits of absolute agreement (LOA) were compared with the specifications for total allowable error (TEa).

Results:

The P values were significant for all measured parameters, with the exception of pCO₂ and K +. Bland-Altman difference plots showed wide LOA for pCO₂, pO₂, HCO₃⁻, Na⁺, K⁺, and Cl⁻ when compared against TEa. For pCO₂, HCO₃⁻, Na⁺, K⁺, and Cl⁻, 40%, 23%, 77%, 34%, and 54% of samples were outside the TEa limits, respectively, with LH.

Conclusion:

Our study showed that there is poor agreement between LH and DBH for the BG parameters pCO2, pO₂, HCO3^-, K⁺, Na⁺, and Cl⁻ and, thus, are not comparable. But for pH and lactate, LH and DBH can be used interchangeably.     

Use of a novel hemoadsorption device for cytokine removal as adjuvant therapy in a patient with septic shock with multi-organ dysfunction: A case study

CytoSorb^® (CytoSorbents Corporation, USA) is a novel sorbent hemoadsorption device for cytokine removal. The aim of this study was to examine the clinical use of CytoSorb^® in the management of patient with septic shock. We used this device as an adjuvant to stabilize a young patient with multi-organ failure and severe sepsis with septic shock. A 36-year-old female patient was hospitalized with the complaints of malaise, general body ache, and breathing difficulty and had a medical history of diabetes mellitus type II, hypertension, obstructive sleep apnea, hypothyroidism and morbid obesity. She was diagnosed to have septic shock with multi-organ dysfunction (MODS) and a low perfusion state. CytoSorb^® hemoadsorption column was used as an attempt at blood purification. Acute physiology and chronic health evaluation score, MODS score, and sequential organ failure assessment score were measured before and after the device application. CytoSorb application as an adjuvant therapy could be considered in septic shock.
