Lekshmi S Bhooshan, M Geetha Devi, R Aniraj, P Binod, M Lekshmi
Background: The skin rejuvenation potential of the autologous emulsified nanofat was studied by Tonnard et al . in 2013. This property is due to the viable adipose-derived stem cells present in the nanofat; although, there are no viable adipocytes. The aim of this study was to determine the aesthetic outcome of autologous emulsified nanofat injection in scars using a standardised and validated Patient Observer Scar Assessment Scale (POSAS) and photographs. Materials and Methods: A total of 34 patients with scars of varied aetiologies were included in the study as per inclusion criteria...

BACKGROUND: The cricothyroid membrane is the most commonly accessed location for invasive surgical airway. Although the laryngeal handshake method is recommended for identifying the cricothyroid membrane, there is no clinical data regarding the utility of the laryngeal handshake method in cricothyroid membrane identification. The objective of this study was to compare the accuracy of cricothyroid membrane identification between the laryngeal handshake method and simple palpation. METHODS: After anaesthesia induction, the otorhinolaryngology resident and anaesthesia resident identified and marked the needle insertion point for cricothyroidotomy using simple palpation and the laryngeal handshake method, respectively...

The pentane extract of the Peruvian plant, Lepidium meyenii (Maca), has been demonstrated to possess neuroprotective activity in previous in vitro and in vivo studies (Pino-Figueroa et al. in Ann N Y Acad Sci 1199:77-85, 2010; Pino-Figueroa et al. in Am J Neuroprot Neuroregener 3:87-92, 2011). This extract contains a number of macamides that may act on the endocannabinoid system (Pino-Figueroa et al. in Ann N Y Acad Sci 1199:77-85, 2010; Pino-Figueroa et al., 2011; Dini et al. in Food Chem 49:347-349, 1994)...

Some important adverse effects of local and regional anaesthesia including injection-site infection, epidural abscess and meningitis, are usually caused by bacteria such as Staphylococcus aureus and Pseudomonas aeruginosa. These infections can even cause the patient's death in severe cases. In the present study, the antimicrobial activity of tramadol was investigated on S. aureus and P. aeruginosa in BALB/c-sensitive mice. This experimental multigroup research study evaluated the effect of two different concentrations of injectable tramadol (12...

INTRODUCTION: Elderly patients constitute an increasingly large proportion of the high-risk surgical group. In adult patients, several specific intraoperative approaches such as cardiac output-guided haemodynamic therapy, depth of anaesthesia monitoring (DAM) or lung-protective ventilation (LPV) are designed to reduce postoperative mortality and surgical complications. However, none of these approaches has been specifically performed in the elderly, and no evaluation of a multimodal optimisation strategy for general anaesthesia has been achieved in this population...

The physiological mechanisms by which anaesthetic drugs modulate oscillatory brain activity remain poorly understood. Combining human data, mathematical and computational analysis of both spiking and mean-field models, we investigated the spectral dynamics of encephalographic (EEG) beta-alpha oscillations, observed in human patients undergoing general anaesthesia. The effect of anaesthetics can be modelled as a reduction of neural fluctuation intensity, and/or an increase in inhibitory synaptic gain in the thalamo-cortical circuit...

ETHNOPHARMACOLOGICAL RELEVANCE: Clitoria ternatea L. (CT), commonly known as Butterfly pea, is used in Indian Ayurvedic medicine to promote brain function and treat mental disorders. Root of CT has been proven to enhance memory, but its role in an animal model of chronic cerebral hypoperfusion (CCH), which has been considered as a major cause of brain disorders, has yet to be explored. AIM OF THE STUDY: To assess the motor and cognitive effects of acute oral administration of CT root methanolic extract and hippocampal long-term plasticity in the CA1 region of the CCH rat model...

BACKGROUND: Currently used pre-operative prediction scores for postoperative pulmonary complications (PPCs) use patient data and expected surgery characteristics exclusively. However, intra-operative events are also associated with the development of PPCs. OBJECTIVE: We aimed to develop a new prediction score for PPCs that uses both pre-operative and intra-operative data. DESIGN: This is a secondary analysis of the LAS VEGAS study, a large international, multicentre, prospective study...

BACKGROUND: Avoidance of airway complications and rapid emergence from anaesthesia are indispensable for the use of a laryngeal mask airway (LMA). Evidence from adequately powered randomised studies with a low risk of bias for the optimal anaesthetic in this context is limited. OBJECTIVE: We tested the hypothesis that when using remifentanil-based intra-operative analgesia, desflurane would be the most suitable anaesthetic: with noninferiority in the occurrence of upper airway complications and superiority in emergence times compared with sevoflurane or propofol...

Tracheal agenesis is a rare but fatal congenital tracheal malformation. Lack of prenatal symptom and a typical clinical presentation lead to failure to arrive at a correct diagnosis and confusion during resuscitation. We report a case of a newborn male child with type 2 tracheal agenesis. Despite a typical presentation, diagnosis was delayed after unsuccessful intubation, examination under anaesthesia and emergency tracheostomy. The embryology, diagnostic criteria and potential treatment options are discussed...

BACKGROUND: In response to rising rates of medical intervention in birth, there has been increased international interest in promoting normal birth (without induction of labour, epidural/spinal/general anaesthesia, episiotomy, forceps/vacuum, or caesarean section). However, there is limited evidence for how best to achieve increased rates of normal birth. In this study we examined the role of modifiable and non-modifiable factors in experiencing a normal birth using retrospective, self-reported data...

Background Brain activation resulting from acute postoperative pain has to our knowledge not previously been studied using positron emission tomography, except from one case study. The aim of this study was to monitor activation in brain sensory pathways during acute pain after surgery of the hand. A secondary aim was to compare brain activation in clinical postoperative pain to that previously reported, by the same research group, for a model of experimental pain from the same body area. Increase in regional cerebral blood flow (rCBF) is presumed to indicate neuronal activation and decrease in blood flow decreased neuronal firing...

Background and objective Perioperative low-dose ketamine has been useful for postoperative analgesia. In this study we wanted to assess the analgesic effect and possible side-effects of perioperative low-dose S (+) ketamine when added to a regime of non-opioid multimodal pain prophylaxis. Methods Seventy-seven patients scheduled for haemorrhoidectomy were enrolled in this randomized, double-blind, controlled study. They received oral paracetamol 1-2 g, total intravenous anaesthesia, intravenous 8 mg dexamethasone, 30 mg ketorolac and local infiltration with bupivacaine/epinephrine...

Background and objectives Unmyelinated C-fibres comprise the largest group of somatic afferents and have demonstrated a crucial role not only in the perception of high-threshold mechanically, thermally or chemically induced pain, but also in non-harmful low-threshold mechanical stimuli [1,2]. The objective of our study was to characterize differential sensitivity changes of C-fibre related subclasses of high-threshold and low-threshold polymodal nociceptors and low-threshold mechanoreceptors to the local anaesthetic (LA) mepivacaine during nerve block of the purely sensory lateral femoral cutaneous nerve (LFCN) in human...

Background Previously we found that pre-procedural nervousness and tension (translated into English as "anxiety"), assessed on a non-validated five-point scale, correlated with pain intensity of the various stages of bone marrow aspiration and biopsy (BMAB). The fewer the previous BMAB procedures the stronger the pain from a repeated procedure. The primary purpose of the present observational study is to evaluate the state of anxiety just before BMAB and to find out whether it affects the pain experiences during the various stages of the BMAB procedure...

Pain after total knee arthroplasty (TKA) is difficult to control. A recently developed and increasingly popular method for postoperative analgesia following knee and hip arthroplasty is Local Infiltration Analgesia (LIA) with ropivacaine, ketorolac and epinephrine. This method is considered to have certain advantages, which include administration at the site of traumatized tissue, minimal systemic side effects, faster postoperative mobilization, earlier postoperative discharge from hospital and less opioid consumption...

Aims Cathepsin S has been reported to be a biomarker of spinal microglial activation, a process suggested to be involved in the pathophysiology of chronic neuropathic pain. So far this has been shown only in animal experiments. The aim of this study was to investigate the concentrations of cathepsin S in human cerebrospinal fluid (CSF) samples from a well-defined patient cohort suffering from neuropathic pain as compared to controls. Methods CSF samples from patients suffering from chronic neuropathic pain (n = 14) were analyzed for cathepsin S levels using commercial sandwich ELISAs (DY1183, R&D Systems, Minneapolis, MN, USA)...
