Outcome of corticosteroid injection versus physiotherapy in the treatment of mild trigger fingers

Salim N, Abdullah S, Sapuan J, Haflah NH

J Hand Surg Eur Vol, 2012 Jan;37(1):27-34.
PMID: 21816888 DOI: 10.1177/1753193411415343

We compared the effectiveness of physiotherapy and corticosteroid injection treatment in the management of mild trigger fingers. Mild trigger fingers are those with mild crepitus, uneven finger movements and actively correctable triggering. This is a single-centred, prospective, block randomized study with 74 patients; 39 patients for steroid injection and 35 patients for physiotherapy. The study duration was from Jun 2009 until August 2010. Evaluation was done at 6 weeks, 3 months and 6 months post-treatment. At 3 months, the success rate (absence of pain and triggering) for those receiving steroid injection was 97.4% and physiotherapy 68.6%. The group receiving steroid injection also had lower pain score, higher rate of satisfaction, stronger grip strength and early recovery to near normal function (findings were all significant, p pain and triggering). Those who received corticosteroid injections had a significant recurrence rate of pain but not triggering. The physiotherapy group had no recurrence of pain or triggering due to the type of triggering responsive to physiotherapy or possibly due to awareness of physiotherapy exercises. Perhaps they were able to institute self-treatment on early onset of symptoms of trigger fingers. We conclude that corticosteroid injection has a better outcome compared to physiotherapy in the treatment of mild trigger fingers but physiotherapy may have a role in prevention of recurrence.

The Malaysian Journal of Nursing, 2019;10(4):83-87.
MyJurnal

Pain is a sensation that is difficult to remember. Pain exposure is a stimulus that can damage the development of the baby's brain and contribute to learning disorders and behavior in childhood. Therefore nursing intervention is needed that can reduce the pain response in infants, especially during hospital treatment. The aim of the study was to determine the effect of non-nutritive sucking (NNS) and ASI (Air Susu Ibu or Breast Milk) on oral responses to acute pain in the neonate when invasive actions were performed. The benefits of research as evidence-based practiced about administering NNS and ASI orally to pain responses in neonates when experiencing pain. The research design uses experimental nonequivalent control group before and after design. The population of all neonates admitted to Dr. Soekardjo Tasikmalaya, with a total sample of 30 respondents consisting of 15 ASI respondents and 15 respondents for the NNS group. Pain assessments instruments CRIES (Crying, Requiring an increase in oxygen, Increased vital sign, Expression, Sleeplessness) was applied. Data analysis used non parametric tests Mann Whitney and Wilcoxon. The results of the study showed no significant differences in pain response before and after the intervention (p-value 0.236). It was suggested that nurses can improve health education for parents to be able to provide breastfeeding during treatment, especially when the baby receives invasive action

Fulltext Profound swim stress-induced analgesia with ketamine

Ahmad AH, Ismail Z, Than M, Ahmad A

Malays J Med Sci, 2008 Jan;15(1):13-22.
PMID: 22589610 MyJurnal

The potential of ketamine, an N-methyl D-aspartate (NMDA) receptor antagonist, in preventing central sensitization has led to numerous studies. Ketamine is increasingly used in the clinical setting to provide analgesia and prevent the development of central sensitization at subanaesthetic doses. However, few studies have looked into the potential of ketamine in combination with stress-induced analgesia. This study looks at the effects of swim stress, which is mediated by opioid receptor, on ketamine analgesia using formalin test. Morphine is used as the standard analgesic for comparison. Adult male Sprague-Dawley rats were assigned to 6 groups: 3 groups (stressed groups) were given saline 1ml/kg intraperitoneally (ip), morphine 10mg/kg ip or ketamine 5mg/kg ip and subjected to swim stress; 3 more groups (non-stressed groups) were given the same drugs without swim stress. Formalin test, which involved formalin injection as the pain stimulus and the pain score recorded over time, was performed on all rats ten minutes after cessation of swimming or 30 minutes after injection of drugs. Combination of swim stress and ketamine resulted in complete analgesia in the formalin test which was significantly different from ketamine alone (p<0.05) and saline with stress (p<0.01). There is no significant difference between ketamine stressed and morphine stressed. These results indicate that ketamine and swim stress act synergistically to produce profound analgesia in the formalin test. This suggests that in the clinical setting, under stressful situations such as operative stress, ketamine is capable of producing profound analgesia at a subanaesthetic dose.

Fulltext Second Courses of Transcranial Magnetic Stimulation (TMS) in Major Depressive Episodes for Initial Responders and Non-Responders

Pridmore S, Erger S, May T

Malays J Med Sci, 2019 May;26(3):102-109.
PMID: 31303854 DOI: 10.21315/mjms2019.26.3.8

Background: Transcranial Magnetic Stimulation (TMS) is effective in major depressive episodes (MDE). However, MDE may follow a chronic, relapsing course, and some individuals may not satisfactorily respond to a first course of TMS.
Objective: To investigate the outcome of second courses of TMS.
Method: A naturalistic investigation-we prospectively studied 30 MDE in-patients and routinely collected information, including pre- and post-treatment with Six-item Hamilton Depression Rating Scale (HAMD6), a six-item Visual Analogue Scale (VAS6) and the Clinical Global Impression-Severity (CGI-S). Two categories of patients were considered: i) those who had remitted with a first course, but relapsed, and ii) those who had not remitted with the first course.
Results: Thirty individuals received a second TMS course. The mean time to the second course was 27.5 weeks. Based on the HAMD6, 26 (87%) achieved remission after the first course, and 22 (73%) achieved remission after the second course. Furthermore, based on the HAMD6 results, of the four patients who did not achieve remission with a first course, three (75%) did so with a second course.
Conclusion: In MDE, a second course of TMS is likely to help those who remitted to a first course and then relapsed, as well as those who did not achieve remission with a first course.

Genesan P, Haspani MSM, Noor SRM

Malays J Med Sci, 2018 Sep;25(5):59-67.
PMID: 30914863 MyJurnal DOI: 10.21315/mjms2018.25.5.6

Background: Many different conventional approaches such as the frontal and pterional approaches are used to access anterior circulation aneurysms. Recently, the supraorbital approach has been widely applied to the treatment of anterior circulation aneurysms. This study was done to evaluate which approach (pterional or supraorbital) has better outcomes in terms of residual neck post-clipping, cosmetic satisfaction, scar tenderness, complications and functional outcomes.
Methodology: A total of 123 patients were recruited into this study, comprising 82 patients who underwent a pterional approach and 41 patients who underwent a supraorbital approach. Computed tomography angiograms, the modified Rankin Scale, and the visual analogue scale were administered at 6 months to look for residual aneurysm, functional outcomes, scar tenderness, and cosmetic satisfaction. Complication data were collected from patients' case notes.
Results: The mean operating time for the pterional group was 226 min, compared to supraorbital group, which was 192 min (P = 0.07). Cosmetic satisfaction was significantly higher (P = 0.001) in the supraorbital group. There was no significant difference between the supraorbital and pterional groups' scar tenderness (P = 0.719), residual aneurysm (P = 0.719), or functional outcomes (P = 0.137), and there was no significant difference between the groups in terms of intra-operative and post-operative complications.
Conclusions: The supraorbital group had better cosmetic outcomes and shorter operating times compared to the pterional group.

Fulltext Intramuscular injection of botulinum toxin for the treatment of wrist and finger spasticity after stroke

Jahangir AW, Tan HJ, Norlinah MI, Nafisah WY, Ramesh S, Hamidon BB, et al.

Med J Malaysia, 2007 Oct;62(4):319-22.
PMID: 18551937 MyJurnal

Botulinum toxin is effective in reducing spasticity post stroke. As there are limited data on post stroke spasticity in Asia, we undertake this study to determine the effectiveness and safety of intramuscular injection of botulinum toxin type-A (BTX-A), in the treatment of chronic focal post-stroke hand spasticity, and the impact of BTX-A on the activities of daily living and quality of life, in comparison to placebo, in Malaysian stroke patients. This was a randomized, double-blind, placebo-controlled study to assess the efficacy and safety of BTX-A in 27 subjects with wrist and finger spasticity after a stroke. The outcome measures were assessed with the Modified Ashworth Scale (MAS) to assess spasticity of the flexor muscles, Barthel Index (BI) for activities of daily living and EQ-5D and EQ VAS for quality of life. Assessments were performed at baseline and 1 and 3 months after injection. Compared to placebo, the BTX-A group had greater improvement in the flexor tone of the wrist and fingers (p = 0.001 and p < 0.001, respectively), at first month follow-up visit and sustained the improvement through to three months. Although there was an improvement in the measures of global function and quality of life in the BTX-A group, there was no significant improvement in between the two groups. No serious BTX-A related adverse effects were reported. The results of this study demonstrate that intramuscular injection of botulinum toxin A is safe and effective in the treatment of chronic focal post-stroke spasticity of the hand.

Fulltext Tolerance and safety to colonoscopy with conscious sedation in Malaysian adults

Ma WT, Mahadeva S, Quek KF, Goh KL

Med J Malaysia, 2007 Oct;62(4):313-8.
PMID: 18551936 MyJurnal

Tolerance to colonoscopy varies between populations and data from the South East Asian region is lacking. We aimed to determine tolerance and safety with to colonoscopy; conscious sedation and identify risk factors for complications in Malaysian adults. Consecutive outpatients undergoing colonoscopy were enrolled prospectively. A combination of pethidine and midazolam were used and tolerance to colonoscopy assessed three hours post-procedure using a validated scale. All patients were monitored for cardiorespiratory depression and risk factors for complications were identified. Two hundred and eight patients (mean age 57.2 +/- 14.8 years, 48% female) were enrolled. The population ethnicity consisted of 45 (21.63%) Malays, 101 (48.56%) Chinese and 56 (26.92%) Indians. Conscious sedation was achieved with 5.0 +/- 1.1 mg of midazolam and 43.3 +/- 14.0 mg of pethidine. Thirty (14.4%) patients tolerated the procedure poorly and independent predictors included female gender (OR 2.93, 95% CI = 1.22 to 7.01) and a prolonged duration of procedure (OR 2.85, 95% CI = 1.08 to 7.48). Hypotension occurred in 13 (6.25%) patients, with age > 65 years as the only risk factor (OR 13.17, 95% CI = 1.28 to 137.92). A prolonged duration was the main cause of hypoxia (OR 5.49, 95% CI = 1.54 to 19.49), which occurred in 6 (2.88%) patients. No major complications occurred during the study period. The current practice of conscious sedation is safe and tolerated well by most adults in our population. However, poor tolerance in a notable minority may have significant clinical implications.

Chan CY, Nam HY, Raveenthiran R, Choon SK, Tai CC

Med J Malaysia, 2008 Jun;63(2):100-3.
PMID: 18942292 MyJurnal

An anaesthetist-led outpatient pre-operative assessment (OPA) clinic was introduced in our unit in an effort to improve patient care and cost-effectiveness. To assess the efficiency of the clinic, 112 patients who attended the OPA clinic (attendance rate 98%) during the first year were assessed prospectively and compared with 118 patients who did not undergo OPA the year before. There were fewer cancellations among those who attended the OPA clinic (13.6% compared to 3.6%), and the hospital stay was shortened from an average of 10.7 days to 7.0 days. This has resulted in more efficient utilization of operating theatre, reduced hospital costs and improved patient satisfaction. More extensive use of the pre-admission clinic is recommended and should be explored in other clinical settings.

Fulltext Quantitative and qualitative evaluation of sural nerve graft donor site

Ng SS, Kwan MK, Ahmad TS

Med J Malaysia, 2006 Dec;61 Suppl B:13-7.
PMID: 17600987

This study is designed to evaluate twenty patients after sural nerve harvest using the single longitudinal incision method. The area of sensory loss to pin prick was assessed by the authors at different intervals. Donor site factors, scar cosmesis, functional status and complications were assessed using a questionnaire. The mean area of anaesthesia at one month was 65 cm2 and it had reduced by 77% to 15 cm2 at one and a half years. The mean area of reduced sensation was 49 cm2 at one month and it increased by 18% to 58 cm2 over the same period. Therefore, the total area of sensory deficit was reduced by 36% from 114 cm2 at one month to 73 cm2 at one and a half years. Subjective patient evaluation indicated moderate level of pain during immediate post surgical period, which reduced significantly at one month. A low level of neuroma symptoms was recorded throughout the study period. At a mean follow-up period of two years, there was no area of anaesthesia in 50% of the patients. Mean area of anaesthesia for all patients was 12 cm2 and mean area of reduced sensation was 55 cm2. Subjective patient evaluation indicated a low level of pain, neuroma symptoms and numbness over the sural nerve sensory distribution. Twenty five percent of the patients were not satisfied with the scar appearance. Function and daily activities were not affected significantly. No surgical complications were observed.

Fulltext The comparison of discomfort level between upper arm and forearm tourniquet

Ng ES, Ting JR, Foo SL, Akram SA, Fadzlina AA, Alywiah JS, et al.

Med J Malaysia, 2006 Dec;61 Suppl B:23-6.
PMID: 17600989

The conventional upper arm tourniquet used for hand and wrist operations may cause significant discomfort to patient when the procedure is performed under local anaesthesia. Forearm tourniquet causes less muscle ischeamia and pain. The discomfort experienced while using a forearm and upper arm tourniquet was assessed in 96 healthy subjects. Tourniquet placed on both sides was inflated sequentially to 250mmhg for five minutes on different hand. The discomfort level was assessed using a small visual analogue scale and complications were recorded. In the upper arm tourniquet, 24.9% had mild, 60.5% had moderate and 14.6% had severe pain whereas with forearm tourniquet, 99% had mild pain and only 1% had moderate pain. Seventy-nine percent of the subjects tested with forearm tourniquet had no discomfort at all. The average discomfort level for upper arm and forearm tourniquet was 4.72 and 0.39 respectively, which is statistically significant. Complications that were observed only in upper arm tourniquet included prolonged tingling, burning sensation and discomfort and stiffness of the upper limb. We concluded that forearm tourniquet was safe and well tolerated and should be used more often when indicated.

Fulltext Pain issues from the palliative perspective: a survey among doctors in Hospital Melaka

Taye GAWC

Med J Malaysia, 2006 Oct;61(4):405-9.
PMID: 17243516

This survey was intended to gauge the management of pain in palliative cancer patients by the doctors in Melaka Hospital. It also sought to identify possible barriers to adequate pain management among doctors and gauge their response to the adequacy of medical school teaching on cancer pain issues. A 39 item survey was used to cover the issues involved. Overall, the doctors displayed a lack of systematic approach to cancer pain management with inadequate knowledge of analgesia handling. Medical school exposure to cancer pain issues was lacking. Formulation of accepted clinical practice guidelines and new education strategies can improve cancer pain management.

Fulltext Adequacy of pain relief in closed manipulative reduction of fracture and dislocation

Wan Hazmy CH, Maizuliana SH, Mastura MT, Norazlina M

Med J Malaysia, 2006 Feb;61 Suppl A:45-9.
PMID: 17042229

Adequate pain relief is a requisite for a successful closed manipulative reduction (CMR) of fractures and dislocations. This prospective study was undertaken to assess the mode and adequacy of pain relief given to patients undergoing such procedures at Seremban Hospital from the 1st April to the 31st May 2001. All patients with fractures and dislocations scheduled to undergo CMR were included in this study. The type of sedative agents and analgesia administered were recorded. Demographic data and the type of fracture or dislocation of the selected patients were documented. A visual analogue scale (VAS) for pain perception was given to both to the patients and the medical personnel who performed the procedure. All data were collected manually before entered into computerized database for analysis. Of 72 patients included in this study, 47% were Malay, 26% Indian, 21% Chinese and 6% others. There was male predominance and the patients' age ranged between 9 to 79 years (average 27.4 years). Upper limb injuries (79%) were mainly fractures of the radius and ulna (29%) and isolated fracture radius (21%). For the lower limb injuries (21%), combined tibia and fibula fractures constituted 10% of the total cases followed by isolated tibia fractures (10%) and hip dislocation (1%). The most common pain relieving agents given during the CMR were intravenous pethidine alone (43%) followed by combination of intravenous pethidine and valium (36%), intramuscular pethidine (17%) and intramuscular tramal (4%). The Visual Analogue Score (VAS) for pain perception revealed that 61% of the patients had moderate pain while 21% had severe pain during the course of the procedures. Suboptimal pain relief administered during CMR should prompt positive actions to ensure that the patient is not subjected to undue pain just for the sake of an acceptable fracture reduction.

Fulltext Pain morbidity in primary care - preliminary observations from two different primary care settings

Zailinawati AH, Teng CL, Kamil MA, Achike FI, Koh CN

Med J Malaysia, 2006 Jun;61(2):162-7.
PMID: 16898306 MyJurnal

The prevalence of pain complaints as a reason for patient-doctor encounters in the local primary care setting is unknown. We performed a cross-sectional survey of such encounters in one public primary care clinic (KK) and 17 general practice clinics (GP), from the city of Seremban, Negeri Sembilan, Malaysia. Reasons for visits were recorded by doctors in KK and medical students in GP using a structured questionnaire. Morbidity data was coded using the International Classification of Primary Care (ICPC-2). A total of 2234 encounters were recorded (80.9% from KK, 19.1% from GP). The overall prevalence of pain complaints was 31.9% with a significant difference between the two cohorts (KK 28.7% and GP 45.2%, p<0.001). Musculoskeletal pain complaints were more common in KK than GP (40.9% versus 29.7%, p<0.05). Of the 3 main ethnic groups in Malaysia (Malay, Chinese and Indian) the Indian patients at KK had the highest prevalence of pain complaints and the Chinese at the GP had the lowest. Thus pain was a common complaint in the two different primary care settings studied. Some of the differences observed are probably due to the differences in the healthcare seeking behaviour of patients consulting at these two settings as well as differences in the payment systems.

Fulltext Apollo total knee replacements in University Malaya Medical Centre: a short-term outcome

Abbas AA, Merican AM, Kwan MK, Mohamad JA

Med J Malaysia, 2006 Feb;61 Suppl A:83-7.
PMID: 17042237

Total knee arthroplasty is the most preferred option for treatment of severe osteoarthritis of the knee. We report the short-term outcome of 48 total knee replacements in 31 patients utilizing the Apollo Total Knee System after an average follow-up of 48 months (range 15 to 70 months). Records of all patients who underwent TKA using Apollo Total Knee System were retrospectively reviewed. Functional outcome was evaluated using visual analogue scale for pain rating and the Oxford 12-item questionnaire. Postoperative radiographs of the replaced knees were assessed by using the Knee Society Total Knee Arthroplasty Roentgenographic Evaluation and Scoring System. Degenerative osteoarthritis was the commonest indication for TKA. The average patient's age was 63.7 years (range, 30-77 years). The mean visual analogue scale for pre- and post-operative pain was eight and zero respectively. The mean Oxford 12-item questionnaire score pre- and post-operatively was 44.8 and 16.5 respectively. Patient satisfaction was notable in 98% of the cases with an average improvement in arc of flexion of 111 degrees. There were four failures; deep infection (one) and aseptic loosening (three) giving rise to a 94% implant survivor. The short-term results of this series is comparable with or better than a number of outcome studies of the Apollo Knee System or other implants of similar design.

Fulltext The safety and efficacy of oral dextrose for relieving pain following venepuncture in neonates

Ling JM, Quah BS, Van Rostenberghe H

Med J Malaysia, 2005 Jun;60(2):140-5.
PMID: 16114153

The objective of this study was to assess the efficacy and safety of oral 30% dextrose during venepuncture in neonates. Neonates admitted in the Special Care Nursery for jaundice from September 200 to January 2001 were recruited for this double-blind randomised controlled trial. The intervention consisted of administration of either 2 ml of oral 30% dextrose or 2 ml of sterile water 2 minutes before venepuncture. The primary outcome measure was the cumulative Neonatal Infant Pain Scale (NIPS) score at 3 minutes after venepuncture and the duration of cry assessed from a videotaped recording. Twenty-six neonates received 30% dextrose and 26 neonates received sterile water. The cumulative NIPS score at 3 minutes (median, IQR) after venepuncture for neonates given 30% dextrose (13, 6.8-21) was significantly (p = 0.03) lower than that for neonates given sterile water (21, 13.8-21). The duration of cry in neonates given 30% dextrose (median 45 sec IQR 1.5-180.8 sec) was significantly (p = 0.03) shorter than that in neonates given sterile water (median 191 sec IQR 52.3-250 sec). No neonates developed diarrhoea, fever or rash during the 24 hour observation period. Both the intra-rater (ICC 0.993 95% CI 0.988-0.996) and inter rater (ICC 0.988 95% CI 0.980-0.993) agreement on the 3-minute NIPS score were good. In conclusion oral 30% dextrose given 2 minutes before venepuncture was effective in reducing neonatal pain following venepuncture. It is a simple, safe and fast acting analgesic and should be considered for minor invasive procedure in term neonates.

Marliana A, Yudianta S, Subagya DW, Setyopranoto I, Setyaningsih I, Tursina Srie C, et al.

Med J Malaysia, 2020 03;75(2):124-129.
PMID: 32281592

INTRODUCTION: In recent years, pulsed radiofrequency (PR) has been used as a minimally invasive pain intervention. However, various studies on the efficacy of PR as modalities for the treatment of radicular pain in lumbar disc herniation have had varied results.
OBJECTIVE: This study aims to determine the efficacy of PR in reducing radicular pain among lumbar disc herniation patients compared with conservative treatment.
METHODS: This study was conducted using the before-andafter quasi experimental design. There were 50 subjects that fulfilled the inclusion and exclusion criteria and they were divided into an intervention group (n=25) and control group (n=25). The intervention group was given once PR in the dorsal root ganglion. All subjects were assessed for Visual Analog Scale (VAS) and Oswestry Disability Index (ODI) before treatment, at 1- , 2- and 4-week after treatment.
RESULTS: At1-, 2- and 4-week, the VAS reduction in the intervention group was statistically significant compared to the control group. Four weeks after the intervention, the VAS score decreased in the intervention group (mean VAS -78.5, SD 16.8) more significantly compared to the control group (p<0.001). The ODI score decreased in the intervention group (mean ODI -61.8, SD 20.1) more significantly than in the control group (p<0.001).
CONCLUSION: Finding showed that at1- , 2- and 4-weekPR was more efficacious in reducing radicular pain among lumbar disc herniation patients compared to the conservative therapy.
