RESUMEN

OBJECTIVE: The present study was taken up to evaluate the combination of two drugs in the management of behavioral disorders such as locomotor activity, muscle relaxation, analgesic, and anxiolytic activity. MATERIALS AND METHODS: In the methodology, Wistar rats weighing (150-180 g) were divided into six groups of 6 each (n=6). All the animals (groups II to VI) were subjected to stress and analyzed for anxiolytic activity using an elevated plus maze. The animals were treated for 28 days with poppy seed oil in lower and higher doses (1,000 and 2,000 mg/kg), tramadol in lower and higher doses (1.5 and 3 mg/kg) as individual groups, and one group with a combination of both drugs in lower doses. RESULTS: The results depicted showed that the combined treatment had significantly (**p <0.001) improvised behavior deficits, extemporized, and diminished anxiety-like attitude in rats, and showed the analgesic property in a significant manner. The pro-inflammatory cytokines TNF-α and IL-1ß were evaluated in the serum and were observed to be lessened the values of both in a significant manner with the co-administration of both the test drugs. The dopamine concentrations were also determined in the serum, which disclosed a decline (**p <0.001) significantly. CONCLUSIONS: It was concluded from the results that a combined effect of drugs might be beneficial in the management of behavioral disorders and pain management.

RESUMEN

OBJECTIVE: To describe a novel wrist deformity in b-thalassemia major patients, and their radiographic and magnetic resonance imaging findings. METHODS: 30 patients with b-thalassemia major who were noticed to have ulnar deviation at wrist joint were evaluated for previous history of medications, serum ferritin levels, presence of pain and swelling at the wrist joint, and the duration of iron chelation therapy. Radiographs of wrist and limited magnetic resonance imaging (MRI) sequences were obtained in 30 and 15 patients, respectively. RESULTS: Radiographs revealed varying severity of distal ulnar shortening, distal radial slanting and presence of soft tissue distal to the ulna. MRI showed similar deformities along with abnormal marrow signal at distal ulnar ends; in 8 patients, a soft tissue distal to the distal end of ulna was noted. CONCLUSIONS: Varying severity of radiological abnormalities, predominantly affecting the distal ulna, are present in children and adolescents with b-thalassemia receiving oral chelation therapy.

RESUMEN

OBJECTIVES: To determine the association of ocular manifestations in beta-thalassemia with the patient's age, blood transfusion requirements, average serum ferritin and dose and duration of iron chelation therapy. METHODS: Sixty multi-transfused beta thalassemia patients of 12 to 18 y of age on chelation therapy were included in this cross-sectional analysis. Structural and functional evaluation of the retina was done using Optical coherence tomography (OCT) and Electroretinography (ERG), including flash ERG and Pattern ERG (PERG). Routine ophthalmic examination and B scan of the eye was also done. Flash ERG a-waves and b-waves were recorded, however only a-wave amplitude was evaluated. Pattern ERG n35, n95 and p50 waves were recorded and p50 wave amplitude was evaluated. The a-wave on flash and p50 on pattern waves represent retinal photoreceptor epithelium (RPE) photoreceptor response, which is mainly affected in beta-thalassemia. RESULTS: Ocular changes were detected in 38.3% and a significant correlation was noted with increase in age (p = 0.045) but not with serum ferritin, transfusion requirements or chelation therapy. Refractive errors were found in 14 cases (23%), such as myopia with astigmatism in 13 (21.7%) and only myopia in 6 subjects (10%). OCT abnormality was noted in 1 patient (1.7%) who had thinning of central retina; right eye 132 µm and left eye 146 µm (n > 200 µm). Abnormalities were noted in a-wave amplitude on flash ERG in 20% of cases, while reduced p50 amplitude on PERG was noted in 15%. CONCLUSIONS: A significant correlation was noted between ocular findings and increase in age, but not with serum ferritin, transfusion requirements or chelation therapy. ERG appears to be a promising tool for screening patients with beta-thalassemia and can serve as a follow-up test for evaluating retinal function.

RESUMEN

OBJECTIVES: To evaluate changes in annual blood transfusion requirements and complications after splenectomy in patients with ß-thalassemia. METHODS: Forty post-splenectomy ß-thalassemic patients aged 8-33 y, receiving regular blood transfusions and chelation therapy were included and non transfusion dependant patients were excluded from this retrospective cross-sectional study. Details about their surgery, transfusion requirements, and platelet levels were recorded on a standard proforma. All patients underwent a B-mode and color-coded duplex sonography of the hepatoportal system during the study period. RESULTS: The average ferritin level in the year prior to the study was 4432 mcg/L (range 480-12,200 mcg/L). The annual blood transfusion requirement in the first year and 5 y post splenectomy [mean ± SD (138.41 ± 90.38 ml/kg/y); (116 ± 41.44 ml/kg/y)] were significantly different from requirements before splenectomy [(mean ± SD) 294.85 ± 226 ml/kg/y; p value <0.001]. There was a significant rise in platelet counts within 24 h post splenectomy with a mean rise of 4,51,000/mm(3) (p value < 0.001). During the follow up period, infections were noted in 50 % of patients, with malaria (18.75 %) being the most common. Doppler study of the portal system in one case showed portal vein thrombosis. CONCLUSIONS: A significant sustained fall in annual blood transfusion requirement and a rise in platelet counts occurred post-splenectomy. Increase in annual blood transfusion requirement should be investigated to find the cause.

RESUMEN

INTRODUCTION: The aim of this study is to analyse the role of cerebral oximetry in combination with awake testing in detecting cerebral ischaemia in patients undergoing carotid endarterectomy (CEA) under local anaesthesia (LA). METHODS: One hundred consecutive patients scheduled for CEA under LA were investigated. Regional oxygen saturation (rSO(2)) was measured with a cerebral oximeter. Cerebral ischaemia was assessed by awake testing in conjunction with rSO(2). Shunting was based solely on deterioration in conscious state assessed by awake testing. The correlation between awake testing and percentage fall in rSO(2) levels was statistically analysed. RESULTS: Patients requiring general anaesthesia were excluded from analysis (n = 17). Seven patients developed deterioration in conscious state and an immediate drop in rSO(2) ≥20% following carotid cross-clamping. Two patients requiring shunting for non-neurological reasons were excluded from analysis. Two patients had a drop in rSO(2) ≥20%, but remained conscious and were not shunted. There were no permanent neurological deficits postoperatively. Statistical analysis showed a sensitivity of 100% with a specificity of 96% yielding a positive predictive value of 81% and negative predictive value of 100% for a ≥19% drop in rSO(2). CONCLUSION: Cerebral oximetry using a cut off ≥19% drop in rSO(2) has a high sensitivity and specificity when compared with awake testing.

RESUMEN

This prospective study describes and evaluates the efficacy of an integrated care pathway for the management of the critically ischaemic diabetic foot patients by a multidisciplinary team. A weekly joint diabetes/vascular/podiatry ward round and outpatient clinic was established where patients were assessed within 7 days of referral by clinical examination, ankle-brachial-index-pressures, duplex angiogram and transcutaneous oxygen pressures. An angiogram +/- angioplasty or alternatively a magnetic resonance angiography prior to surgical revascularisation was performed in patients deemed not suitable for angioplasty based on the above vascular assessment. Between January 2002 and June 2003(18 months), 128 diabetic patients with lower limb ischaemia were seen. Thirty-four (26.6%) patients received medical treatment alone, and 18 (14.1%) were deemed 'palliative' due to their significant co-morbidities. The remaining 76 (59.4%) patients underwent either angioplasty (n = 56), surgical reconstruction (n = 18), primary major amputation (n = 2) or secondary amputation after surgical revascularisation (n = 1). Minor toe amputations were required in 35 patients. The mortality in the intervention group was 14% (11/76). This integrated multidisciplinary approach offers a consistent and equitable service to diabetic patients with critically ischaemic feet and appears to have a beneficial major/minor amputation ratio.
