ABSTRACT

The use of tourniquet is common in orthopaedic surgeries as it reduces blood loss, enhances visualization of the operating field, and leads to quicker procedures. However, the use of tourniquet has certain risks which can be avoided by following guidelines like British Orthopaedic Association Standards for Trauma (BOAST) guidelines for safe use of tourniquet. This audit study was done in a District general hospital to check the compliance of two trauma theatres with BOAST guidelines. The audit found that there was poor documentation of tourniquet details in the operation notes (10%). Regarding tourniquet time and pressure, the compliance in the two theatres was 95 % & 97.5 %. The recommendations of this audit were to use a template to improve documentation of tourniquet details in the operation notes and training of theatre staff on BOAST guidelines for safe use of tourniquet.

ABSTRACT

The restoration of the joint line is important for a good functional outcome after a Total Knee Arthroplasty(TKA). Knee joint biomechanics need to be restored as near normal as possible. Joint line elevation leads to anterior knee pain, decrease in range of motion, patella baja ,mid-flexion instability and impingement of patellar tendon. Joint line depression on the other hand leads to patella alta, risk of patellar subluxation and mid-flexion instability of the knee. Various studies have demonstrated various range of acceptable joint line variation but there is no clear acceptable range of joint line variation. More studies are required for establishing the acceptable range of joint line variation and standard practices should be established for arthroplasty surgeons for preventing variation of joint line.

ABSTRACT

Fractures of the metacarpal particularly the 5th metacarpal is quite common among all hand fractures and has a high incidence in male adult population. Proper management of these fractures plays a key role in rehabilitation and early return to work thus reducing the economic burden. Treatment of these injuries depends on the type of injury: whether it is a closed/open fracture, degree of angulation at the fracture site and also mal-rotation and shortening of the finger. Non-operative management is suitable for fractures which are closed, non-displaced and without angulation or rotation. Open fractures, fractures with angulation and/or mal-rotation and fractures with neuro-vascular injury are more suitable for operative management. The acceptable angulation for conservative management for most studies is 70 degrees. Buddy strapping with a Futura splint provides good functional results. In fractures requiring operative intervention, K-wire fixation is a minimally invasive method of fixation, which in most cases has good functional results. Plate and screw fixation, however, is preferred for cases with significant comminution or multiple metacarpal fractures.

ABSTRACT

Traditionally, it was believed that both proximal and distal locking are essential for achieving stability during intra-medullary fixation for extra-capsular hip fractures. However, recent literature has presented varying perspectives on the necessity of distal locking. Distal locking plays a significant role in managing hip fractures with uncertainties regarding longitudinal and rotational stability. This includes cases of comminuted intertrochanteric fractures with subtrochanteric extension, reverse oblique and high oblique fractures, broad medullary canals, comminution of the lateral wall, diaphyseal fractures, and large posteromedial fragments extending below the level of the lesser trochanter. In stable pertrochanteric fractures, with the lag screw passing through the lateral cortex of the distal fragment, may not require a distal locking screw. Distal locking has been associated with potential complications, including irritation of the fascia lata, prolonged operation time, increased radiation exposure, greater blood loss, implant loosening, secondary femoral stress fractures, and damage to the femoral artery. Thus, although distal locking is of doubtful significance in stable pertrochanteric fractures it is essential in unstable fracture patterns.

ABSTRACT

PURPOSE: Sensory hypersensitivity is a frequently reported complaint after acquired brain injury (ABI). This study explores patients' perceptions of sensory hypersensitivity following ABI and its impact on everyday life. MATERIALS AND METHODS: Semi-structured interviews were conducted with 18 patients with ABI (stroke, brain tumour, TBI) who reported complaints of sensory hypersensitivity. Interview data were analysed using qualitative thematic analysis. RESULTS: Six themes emerged from the data: (1) definition of sensory hypersensitivity, relating to individual perceptions of sensory hypersensitivity; (2) type of sensory stimuli, relating to the variety of stimuli that patients may be sensitive to; (3) course, relating to changes in sensory hypersensitivity following ABI; (4) fatigue, relating to its association with sensory hypersensitivity; (5) consequences of sensory hypersensitivity, relating to the physical, social and emotional impact of sensory hypersensitivity on patients' lives; and (6) coping strategies, relating to behaviours used to cope with sensory hypersensitivity. CONCLUSIONS: Sensory hypersensitivity can have a major impact on patients' physical well-being, return to work and (social) participation after ABI. Characteristics of sensory hypersensitivity vary between patients with ABI. To develop treatments for sensory hypersensitivity, future studies should focus on cognitive (e.g., filtering information) and psychological factors (e.g., coping) in relation to sensory hypersensitivity.


Sensory hypersensitivity occurs in all types of acquired brain injury (ABI).It is important to ask an ABI patient how sensory hypersensitivity is experienced.It is recommended to investigate the physical (e.g., headache) and emotional (e.g., irritability, anger, frustration) consequences of sensory hypersensitivity and its impact on return to work and social participation.When the patient mentions sensory hypersensitivity, also map cognition (with a focus on attention), fatigue, stress, and coping.

ABSTRACT

BACKGROUND: The purpose of awake brain tumor surgery is to maximize the resection of the tumor and to minimize the risk of neurological and cognitive impairments. The aim of this study is to gain understanding of the development of possible postoperative cognitive deficits after awake brain tumor surgery in patients with suspected gliomas, by comparing preoperative, early postoperative, and late postoperative functioning. A more detailed timeline will be helpful in informing candidates for surgery about what to expect regarding their cognitive functioning. METHODS: Thirty-seven patients were included in this study. Cognitive functioning was measured by means of a broad cognitive screener preoperatively, days after surgery and months after surgery in patients who underwent awake brain tumor surgery with cognitive monitoring. The cognitive screener included tests for object naming, reading, attention span, working memory, inhibition, inhibition/switching, and visuoperception. We performed a Friedman ANOVA to analyze on group level. RESULTS: Overall, no significant differences were found between preoperative cognitive functioning, early postoperative cognitive functioning, and late postoperative cognitive functioning, except for performances on the inhibition task. Directly after surgery, patients were significantly slower on this task. However, in the following months after surgery, they returned to their preoperative level. CONCLUSION: The timeline of cognitive functioning after awake tumor surgery appeared overall stable in the early and late postoperative phase, except for inhibition, which is more difficult in the first days after awake brain tumor surgery. This more detailed timeline of cognitive functioning, in combination with future research, can possibly be contributing in informing patients and caregivers what to expect after awake brain tumor surgery.

ABSTRACT

Fluoroscopy is an indispensable tool that forms a significant part of the standard practice in many trauma and orthopaedic (T&O) procedures, as it facilitates dynamic assessment and aids intraoperative visualization and decision-making. It exposes patients and theatre staff to the potential hazards of ionizing radiation. Thus, the awareness of these hazards and proper use of personal protective equipment (PPE) will help mitigate increased exposure. This audit aimed to assess awareness regarding the safe use of fluoroscopy in T&O theatres, evaluate the level of PPE use and the knowledge of relevant guidelines, such as the British Orthopaedic Association (BOA) recommendations and local trust policy.A prospective audit was performed between June and July 2023 using an online survey sent to healthcare professionals working in T&O theatres across two hospital sites. Data were collected using an online questionnaire and responses kept anonymous and thus implied consent was applied. Standards followed the local trust policy at the University Hospitals Sussex NHS Trust and the BOA guidelines.Of the 49 respondents, 59% were fully aware of radiation hazards, and only the theatre radiographers were all fully aware. Surgeons (56%) and anaesthetists (46%) considered themselves to have adequate knowledge of these hazards. Just over half of the respondents (69%) could identify the major source of radiation, while only 37% understood the effect of distance on dose exposure. Of those surveyed, 49% knew the local trust policy, while 39.6% knew the BOA guidelines; less than half had formal training (40.8%). The results showed that less than half of the participants used the full PPE highlighted in the guidelines. Statistical analysis showed that only 46% of participants used a protective lead apron/lead skirt with a coat and thyroid shield. Of the survey participants, 84% never used eye protection during fluoroscopy procedures, and 58% had never received any formal training on radiation safety.The findings from this audit highlight the lack of awareness of the guidelines, resulting in suboptimal use of PPE in procedures with fluoroscopy. Recommendations for improvement include mandatory training for all theatre personnel. Methods of increasing awareness include using posters, performing regular audits to monitor the usage of PPE, and discussing the results in clinical governance meetings.

ABSTRACT

Orthopaedic surgeries pose various risks to the health of orthopaedic surgeons: radiation, noise, infection, chemical exposure, and musculoskeletal injury. These are associated with short and long-term health problems including malignancy and teratogenicity. Orthopaedic surgeons' health is critical to ensure optimal patient care. Most of these hazards can be obviated or minimized by adopting rigorous prevention protocols and raising awareness. Further related research is warranted and guidelines regarding prevention need to be framed by regulatory bodies.

ABSTRACT

This study describes the size distribution and concentration of particles expelled by a portable, 3-L ultrasonic humidifier. The ultrasonic humidifier was filled with waters of varying mineral content and hardness. Aerosol size distributions were measured during 8 hours of humidifier operation in a typical bedroom. Humidifiers produced approximately 1.22 × 1010 -2.50 × 1010 airborne particles per milliliter of water consumed, resulting in airborne particle concentrations of 3.01-5.91 × 104  #/cm3 , with modes ranging between 109 and 322 nm in diameter. The emission rate of particles varied by water type from 1.02 × 109 to 2.27 × 109  #/s. Lower mineral waters produced fewer, smaller particles when compared to higher mineral waters. Chemical analyses of particles collected with a cascade impactor indicated that the minerals in emitted particles had the same relative mineral concentrations as the fill water. Our results demonstrate that ultrasonic humidifiers should be considered a source of inhalation exposure to minerals dissolved in water, and that the magnitude of exposure to inhalable particles will vary with water quality.

ABSTRACT

This study was designed to assess the effects of rivastigmine (Exelon) on the cognitive functioning of patients suffering from dementia with Lewy bodies. This was a prospective, multi-centre, randomised, double-blind, placebo-controlled exploratory study conducted at sites in the UK, Spain and Italy. The treatment period was 20 weeks with a 3-week posttreatment follow-up. The primary outcome measures were the Cognitive Drug Research (CDR) computerised assessment system and the Neuropsychiatric Inventory. Testing was conducted prior to dosing and then again at weeks 12, 20 and 23. Analysis of the data from the 92 patients who completed the study identified a significant pattern of benefits of rivastigmine over placebo on the CDR system. These benefits were seen on tests of attention, working memory and episodic secondary memory. Taking attention for example, patients given placebo showed a significant deterioration from predosing scores at 12 and 20 weeks, whereas patients on rivastigmine performed significantly above their predosing levels. These effects were also large in magnitude, the decline under placebo at week 12 being 19%, while the improvement under rivastigmine was 23%. The clinical relevance of this 23% improvement was that it took the patients 33% towards being normal for their age on this assessment of attention. These benefits to cognitive function were accompanied by a significant improvement of the other primary outcome measure, the Neuropsychiatric Inventory. Three weeks after discontinuation of rivastigmine, most parameters of cognitive performance returned to predrug levels.

ABSTRACT

BACKGROUND: Colorectal cancer is one of the most common malignancies in the West, but in Asia the incidence is low. However in Malaysia, colorectal cancer is increasing with a reported figure of 15% of all cancer cases. Adjuvant chemo and radiotherapy are now more frequently used in such patients. The present retrospective analysis was performed to document the effect of such therapy among patients with colorectal cancer in Malaysia. MATERIALS AND METHODS: This is a retrospective study on the use of adjuvant treatment in colorectal cancers. Patients with histopathological evidence of risk factors were subjected to adjuvant radiotherapy and/or chemotherapy. Cancers confined to rectum and rectosigmoid were subjected to pelvic radiotherapy to a tumor dose of 45 Gy in 20 fractions over 4-week period. 5-flurouracil based chemotherapy was predominantly offered for colonic cancers. RESULTS: One hundred thirty patients with colorectal cancers received adjuvant treatment with a median age of 58 years (range 22-76 years). The male to female ratio was 1.4:1. There were 76% Malays, 19% Chinese, 2% Indians and 3% Siamese subjects in this study. Modified Dukes' stage B2 (28%) and C (38%) constituted the majority, which were distributed in rectum (40%), rectosigmoid (19%), and in the remaining colon (41%). Thirty-one patients received 5-fluorouracil with folinic acid based regime and 35 patients received 5-fluorouracil with levamisole based regimen. Locoregional radiotherapy was offered to 56 (43%) patients. Following treatment, the 2-year actuarial survival was 28% and 54% in colon and rectum cancer respectively. CONCLUSIONS: This study showed that colorectal cancer is not infrequent among Malays in this region and rectal cancers had better survival than the colonic cancers.

ABSTRACT

OBJECTIVES: To describe the baseline demographic, neuropsychiatric and neurological data of a large selected clinical sample of patients with dementia with Lewy Bodies (DLB) from an international multicentre trial with rivastigmine. To examine the usefulness of the Consensus Criteria for the diagnosis of DLB in different countries. METHODS: Seventeen centres from Spain, the UK and Italy recruited patients diagnosed clinically as probable DLB according to recent Consensus Criteria (McKeith et al., 1996). A standard clinical protocol including inclusion/exclusion criteria, collection of demographic and medical data, cognitive (Mini Mental State Examination: MMSE), motor (Unified Parkinson's Disease Rating Scale: UPDRS) and neuropsychiatric (Neuropsychiatric Inventory: NPI) examinations, was applied after obtaining informed consent. Data were summarised and compared across countries with uni- and multivariate analyses. RESULTS: One hundred and twenty patients were recruited: 56.7% males, mean (SD) age 73.9 (6.4) years, range 57 - 87 years. Sixty percent fulfilled all three core diagnostic features of DLB, and 40% only two ('parkinsonism' 92.4%, 'cognitive fluctuations' 89.1%, 'visual hallucinations' 77.3%). 'Systematised delusions' (46%) and 'repeated falls' (42%) were the most frequent supportive diagnostic features. There were no differences across countries in demographic, diagnostic or clinical features. Patients showed a wide range of psychopathology which was weakly correlated with cognitive impairment. Some mild extrapyramidal signs (EPS) were observed in most patients. CONCLUSIONS: The Consensus Criteria for DLB can be consistently applied across many different sites for multicentre studies. 'Parkinsonism' and 'cognitive fluctuations' as core features and 'systematised delusions' and 'repeated falls' as supportive features are the most frequent diagnostic clues. Neuropsychiatric disturbances, in particular apathy, delusions, hallucinations and anxiety, and mild symmetric EPS are frequent in DLB and are only related weakly to cognitive impairment.

ABSTRACT

BACKGROUND: Dementia with Lewy bodies is a common form of dementia in the elderly, characterised clinically by fluctuating cognitive impairment, attention deficits, visual hallucinations, parkinsonism, and other neuropsychiatric features. Neuroleptic medication can provoke severe sensitivity reactions in patients with dementia of this type. Many deficits in cholinergic neurotransmission are seen in the brain of patients with Lewy-body dementia; therefore, drugs enhancing central cholinergic function represent a rationally-based therapeutic approach to this disorder. Rivastigmine, a cholinesterase inhibitor, was tested in a group of clinically characterised patients with Lewy-body dementia. METHODS: A placebo-controlled, double-blind, multicentre study was done in 120 patients with Lewy-body dementia from the UK, Spain, and Italy. Individuals were given up to 12 mg rivastigmine daily or placebo for 20 weeks, followed by 3 weeks rest. Assessment by means of the neuropsychiatric inventory was made at baseline, and again at weeks 12, 20, and 23. A computerised cognitive assessment system and neuropsychological tests were also used, and patients underwent close medical and laboratory safety analysis. FINDINGS: Patients taking rivastigmine were significantly less apathetic and anxious, and had fewer delusions and hallucinations while on treatment than controls. Almost twice as many patients on rivastigmine (37, 63%), than on placebo (18, 30%), showed at least a 30% improvement from baseline. In the computerised cognitive assessment system and the neuropsychological tests, patients were significantly faster and better than those on placebo, particularly on tasks with a substantial attentional component. Both predefined primary efficacy measures differed significantly between rivastigmine and placebo. After drug discontinuation differences between rivastigmine and placebo tended to disappear. Known adverse events of cholinesterase inhibitors (nausea, vomiting, anorexia) were seen more frequently with rivastigmine than with placebo, but safety and tolerability of the drug in these mostly multimorbid patients were judged acceptable. INTERPRETATION: Rivastigmine 6-12 mg daily produces statistically and clinically significant behavioural effects in patients with Lewy-body dementia, and seems safe and well tolerated if titrated individually.

ABSTRACT

OBJECTIVES: To assess the effects of rivastigmine on the core domains of Alzheimer's disease. DESIGN: Prospective, randomised, multicentre, double blind, placebo controlled, parallel group trial. Patients received either placebo, 1-4 mg/day (lower dose) rivastigmine, or 6-12 mg/day (higher dose) rivastigmine. Doses were increased in one of two fixed dose ranges (1-4 mg/day or 6-12 mg/day) over the first 12 weeks with a subsequent assessment period of 14 weeks. SETTING: 45 centres in Europe and North America. PARTICIPANTS: 725 patients with mild to moderately severe probable Alzheimer's disease diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, fourth edition, and the criteria of the National Institute of Neurological and Communicative Disorders and Stroke and the Alzheimer's Disease and Related Disorders Association. OUTCOME MEASURES: Cognitive subscale of the Alzheimer's disease assessment scale, rating on the clinician interview based impression of change incorporating caregiver information scale, and the progressive deterioration scale. RESULTS: At the end of the study cognitive function had deteriorated among those in the placebo group. Scores on the Alzheimer's disease assessment scale improved in patients in the higher dose group when compared with patients taking placebo (P<0.05). Significantly more patients in the higher dose group had improved by 4 points or more than had improved in the placebo group (24% (57/242) v 16% (39/238)). Global function as rated by the clinician interview scale had significantly improved among those in the higher dose group compared with those taking placebo (P<0.001), and significantly more patients in the higher dose group showed improvement than did in the placebo group (37% (80/219) v 20% (46/230)). Mean scores on the progressive deterioration scale improved from baseline in patients in the higher dose group but fell in the placebo group. Adverse events were predominantly gastrointestinal, of mild to moderate severity, transient, and occurred mainly during escalation of the dose. 23% (55/242) of those in the higher dose group, 7% (18/242) of those in the lower dose group, and 7% (16/239) of those in the placebo group discontinued treatment because of adverse events. CONCLUSIONS: Rivastigmine is well tolerated and effective. It improves cognition, participation in activities of daily living, and global evaluation ratings in patients with mild to moderately severe Alzheimer's disease. This is the first treatment to show compelling evidence of efficacy in a predominantly European population.

ABSTRACT

We carry out a self-consistent calculation of the structure functions in the dissipation range using the Navier-Stokes equation. Combining these results with the known structures in the inertial range, we actually propose crossover functions for the structure functions that take one smoothly from the inertial to the dissipation regime. These crossover functions are shown to exhibit extended self-similarity properties consistent with experimental findings.
