Prediction of functional outcomes in stroke inpatients receiving rehabilitation.

BACKGROUND AND PURPOSE: Early identification of predictive factors relevant to functional outcomes for stroke patients is important to the establishment of an effective continuing care program. The objective of this study was to identify the predictive factors related to functional outcome at discharge after stroke rehabilitation therapy. METHODS: 105 first-time stroke patients admitted to the inpatient rehabilitation department of a university-based medical center were recruited for this prospective study. The functional outcomes of the patients were assessed at admission and at discharge using the Functional Independence Measure (FIM). Severity of stroke was determined using the Canadian Neurological Scale (CNS). Age, gender, side of hemiplegia (SIDE), type of stroke (TYPE), onset to admission interval (OAI), and length of rehabilitation stay (LORS) were also included as predictor variables. RESULTS: The mean (+/- SD) FIM score at discharge (76.6 +/- 26.4) correlated strongly (r = 0.78, p < 0.001) with the admission FIM score (56.3 +/- 24.1), moderately (r = 0.46, p < 0.001) with the admission CNS score (6.1 +/- 2.2), negatively (r = -0.38, p < 0.001) with age (63.2 +/- 12.3 years), negatively (r = -0.26, p = 0.009) with OAI (24.2 +/- 16.0 days), and negatively (r = -0.29, p = 0.002) with LORS (34.7 +/- 16.8 days). Stepwise regression analyses indicated that admission FIM score, age, and admission CNS score were the strongest predictors of functional outcome and accounted for 66% of the total variation in discharge FIM total score. The admission FIM score was the best predictor and accounted for 61% of the variation. CONCLUSIONS: The findings of this study imply that the admission FIM scores for inpatients receiving stroke rehabilitation can be used to predict functional outcomes at discharge from hospital.

Status epilepticus as an initial presentation of Brugada syndrome: a case report

Patients presenting with convulsions are sometimes incorrectly treated for epilepsy, as these symptoms may be manifestations of underlying cardiac disease. Brugada syndrome, associated with an elevated risk of developing fatal arrhythmic events, is a rare disorder characterized by a unique electrocardiographic pattern. The typical clinical presentation mainly involves syncope of unclear cause or sudden death. Seizures are uncommon clinical manifestations of Brugada syndrome, and reports of status epilepticus as initial presentation of Brugada syndrome are extremely rare. In this case report, we present a male patient with a typical pattern on 12-lead electrocardiography, following resuscitation for generalized convulsive status epilepticus.     

Medical doctors’ knowledge of dental trauma management: A review

Education in dental trauma is extremely important to promote knowledge on the assessment and management of a traumatized tooth. Medical doctors are normally only required to manage the emergency phase of traumatic dental injury (TDI) treatment before referring to a dentist, endodontist or oral and maxillofacial surgeon for continuing care. Medical doctors who possess sufficient theoretical knowledge and are competent enough clinically to handle TDI can provide a higher standard of treatment care and ultimately achieve a better patient outcome. The aim of this literature review was to assess the extent of medical doctors’ knowledge of dental trauma management for injuries in the following four areas: (a) tooth structure; (b) to the supporting bone; (c) to the periodontal tissues; and (d) to the soft tissues. Based on the findings from this literature review, an overall deficiency in knowledge and confidence in managing dental trauma has been identified. Knowledge and understanding to categorize TDI using the same classification of dental injuries commonly used amongst dentists would allow medical doctors to better manage and communicate with dental colleagues concerning referral for further care. If the medical education curriculum provided medical doctors with more information and skills for the management of dental trauma and an understanding of the importance of early management, then more favourable outcomes may prevail for dental trauma patients.     

Management of choledocholithiasis in an emergency cohort undergoing laparoscopic cholecystectomy: a single-centre experience

Introduction

Minimally-invasive options for the management of choledocholithiasis in patients undergoing laparoscopic cholecystectomy include laparoscopic and endoscopic approaches. This study reviews the effectiveness of both approaches in an emergency setting.

Methods

A retrospective chart review was performed for a cohort of patients who underwent laparoscopic cholecystectomy. Outcomes assessed were duct clearance, the number of procedures performed (NPP), length of stay (LOS) and complication rate.

Results

A total of 182 patients who underwent emergency laparoscopic cholecystectomies received intervention for choledocholithiasis. The duct clearance rate was lower in the laparoscopic group, 63% versus 86% (P = 0.001). However, the median NPP was also lesser in the laparoscopic group, 1 (interquartile range (IQR) 1–2) versus 2 (IQR 2–2) (P < 0.001), as was the median LOS, 5 days (IQR 3–8) versus 7 days (IQR 6–10) (P = 0.009). Forty-eight laparoscopic endobiliary stents were attempted; stent deployment was successful in 37 patients. A larger proportion of patients with laparoscopic endobiliary stents had duct clearance by endoscopic retrograde cholangiopancreatography (ERCP) compared with those without, although this was not statistically significant (P = 0.208).

Conclusion

Laparoscopic clearance is not as effective as post-operative ERCP in an emergency cohort, but is associated with fewer procedures required and a shorter inpatient stay. Thus, laparoscopic clearance may still be an attractive option for surgeons especially where conditions are favourable during an emergency laparoscopic cholecystectomy.     

Methadone in post-herpetic neuralgia: A pilot proof-of-concept study

OBJECTIVE:

This research was designed as a pilot proof-of-concept study to evaluate the use of low-dose methadone in post-herpetic neuralgia patients who remained refractory after first and second line post-herpetic neuralgia treatments and had indications for adding an opioid agent to their current drug regimens.

METHODS:

This cross-over study was double blind and placebo controlled. Ten opioid naïve post-herpetic neuralgia patients received either methadone (5 mg bid) or placebo for three weeks, followed by a 15-day washout period and a second three-week treatment with either methadone or placebo, accordingly. Clinical evaluations were performed four times (before and after each three-week treatment period). The evaluations included the visual analogue scale, verbal category scale, daily activities scale, McGill pain questionnaire, adverse events profile, and evoked pain assessment. All patients provided written informed consent before being included in the study. ClinicalTrials.gov: {"type":"clinical-trial","attrs":{"text":"NCT01752699","term_id":"NCT01752699"}}NCT01752699

RESULTS:

Methadone, when compared to placebo, did not significantly affect the intensity of spontaneous pain, as measured by the visual analogue scale. The intensity of spontaneous pain was significantly decreased after the methadone treatment compared to placebo on the category verbal scale (50% improved after the methadone treatment, none after the placebo, p = 0.031). Evoked pain was reduced under methadone compared to placebo (50% improved after the methadone treatment, none after the placebo, p = 0.031). Allodynia reduction correlated with sleep improvement (r = 0.67, p = 0.030) during the methadone treatment. The side effects profile was similar between both treatments.

CONCLUSIONS:

Methadone seems to be safe and efficacious in post-herpetic neuralgia. It should be tried as an adjunctive treatment for post-herpetic neuralgia in larger prospective studies.     

Correlation between the ossification of nuchal ligament and clinical cervical disorders

This is a correlation analysis between severity of the ossification of the nuchal ligament (ONL) and clinical cervical disorders including neck dysfunction, cervical malalignment, and morphologic changes of the cervical neural foramen (CNF). The clinical effects of ONL on active range of motion (AROM) of neck, cervical radiculopathy, abnormal cervical curvature, and the degree of CNF stenosis in patients with painful neck stiffness are investigated. Studies have investigated the predisposing factors to cervical dysfunction and degenerative disorders; however, few studies have examined the influence of the ONL on neck function and cervical spine. A total of 31 participants with painful neck stiffness were recruited. They accepted measurement of cervical AROM and serial cervical radiographs at anterior–posterior view, lateral view, and bilateral oblique views. Parameters of radiographs measurement included cervical lordotic curve, and cross-sectional areas (CSA) of the ONL and CNF (C2–C3, C4–C5, C5–C6, and C6–C7 levels). The ratio of CSA of the lower CNF (C4–C5, C5–C6, C6–C7) to CSA of the upper CNF (C2–C3) was used as a CNF stenosis ratio. The correlations of ONL size, neck symptoms, cervical AROM, lordotic curve, and CNF stenosis ratio were analyzed. More than half of all patients were positive in cervical root signs and prone to have larger ONL. Neck AROM of all participants was significantly below normal average in all directions, and a moderate negative association was found between the ONL CSA and AROM in flexion–extension. Most patients had moderate loss of cervical lordotic curve despite there being no significant correlation between ONL CSA and cervical curvature. Moreover, CNF stenosis ratio significantly negatively correlated with ONL CSA. Patients with larger ONL had more severe cervical radiculopathy, more stiffness in flexion–extension direction, more complex degenerative change of spine, and worse CNF stenosis.     

Effects of helium-neon laser on levels of stress protein and arthritic histopathology in experimental osteoarthritis

OBJECTIVE: To investigate the effect of low-power laser therapy on levels of stress proteins (SPs) in experimental arthritis and their relation to the bioeffects on arthritic cartilage repair. DESIGN: A total of 42 rats with similar degrees of induced arthritis evaluated by means of bone scan were divided randomly into two groups. In the treated group, 21 rats received helium-neon laser treatment; in the control group, 21 rats received sham laser treatment. The changes in chondrocytes of SPs were measured by electrophoresis of proteins extracted from chondrocytes of arthritic cartilage at various time periods. The histopathologic changes and the presence of SP of arthritic cartilage were identified by hematoxylin and eosin stain and by immunostains of SP72 antibody individually from frozen sections of arthritic cartilage. RESULTS: SP density increased markedly in rats after laser treatment and was closely related to the repair of arthritic cartilage. Furthermore, the pathohistology of arthritic cartilage improved significantly with the decline of SP levels in the follow-up period. CONCLUSION: Helium-neon (632 nm) low-power laser can enhance SP production in arthritic chondrocytes. The extragenic production of SP is well correlated with the therapeutic effect of low-power laser in preserving chondrocytes and the repair of arthritic cartilage in rats.
