Background and Aims:Different additives have been used to prolong brachial plexus block. We evaluated the effect of adding dexmedetomidine to ropivacaine for supraclavicular brachial plexus blockade. The primary endpoints were the onset and duration of sensory and motor block and duration of analgesia.Materials and Methods:A total of 84 patients (20-50 years) posted for elective forearm and hand surgery under supraclavicular brachial plexus block were divided into two equal groups (Group R and RD) in a randomized, double-blind fashion. In group RD (n = 42) 30 ml 0.5% ropivacaine +1 ml (100 μg) of dexmedetomidine and group R (n = 42) 30 ml 0.5% ropivacaine +1 ml normal saline were administered in supraclavicular block. Sensory and motor block onset times and block durations, time to first analgesic use, total analgesic need, postoperative visual analog scale (VAS), hemodynamics and side-effects were recorded for each patient.Results:Though with similar demographic profile in both groups, sensory and motor block in group RD (P < 0.05) was earlier than group R. Sensory and motor block duration and time to first analgesic use were significantly longer and the total need for rescue analgesics was lower in group RD (P < 0.05) than group R. Post-operative VAS value at 12 h were significantly lower in group RD (P < 0.05). Intra-operative hemodynamics were significantly lower in group RD (P < 0.05) without any appreciable side-effects.Conclusion:It can be concluded that adding dexmedetomidine to supraclavicular brachial plexus block increases the sensory and motor block duration and time to first analgesic use, and decreases total analgesic use with no side-effects.

The studied combination of glucosamine HCl, sodium chondroitin sulfate and manganese ascorbate was found to be effective for the treatment of radiographically mild to moderate OA of the knee as measured by the ISK. This is the first U.S. study of these agents.

Background:Pityriasis rosea (PR) is an acute inflammatory dermatosis. The association of human herpes virus 6 and 7 suggests the utility of use of antiviral agents in this disease.Aims and Objectives:To evaluate the effectiveness and safety of acyclovir in the treatment of PR.Methods:An observer-blind, randomized (1:1), parallel group, add-on trial was conducted on 24 adult patients with PR. Subjects of both Group A and B received the standard of care in the form of cetirizine 10 mg OD and calamine. Group A in addition received acyclovir 400 mg tablets thrice daily for 7 days. Both groups were followed up for four consecutive weeks for assessment of effectiveness and adverse events.Results:Group A complained of significantly fewer new lesions than Group B (P = 0.046). A complete response was obtained in all patients of Group A and 83% patients of Group B at the end of the follow up period. There was significant reduction in both lesional score and pruritus at second week follow-up in Group A and third week follow-up in Group B (P < 0.05). Minor adverse effects were observed in both treatment arms.Conclusion:Acyclovir offered rapid resolution of clinical severity of PR from second week onwards without significantly increased adverse events as compared to supportive therapy alone.

Neck is the most common site of peripheral lymph node enlargement and is very frequently encountered in oto-laryngological practice. This study was done to delineate distribution of clinico-demographic parameters in patients presenting with cervical lymphadenopathy in the otolaryngology out-patient department of a state hospital in India in a 1 year period and to correlate them with fine needle aspiration cytological diagnosis. Record-based cross sectional study in the department of Otolaryngology and department of Pathology, Calcutta National Medical College and Hospital, Kolkata. Case reports and cytological reports of 423 patients who underwent Fine Needle Aspiration Cytology (FNAC) of cervical lymph nodes between January 2009 and December 2009 were reviewed in relation to their demographic and clinical profiles. The cases were divided into three groups according to age and different parameters were described according to these groups. In the cyto-pathological diagnosis, tubercular lymph-adenitis was most prevalent diagnosis (45.4%). Among the metastatic secondaries, squamous cell carcinoma was most common (8.5%). Non-specific/reactive lymphadenitis was significantly more common in \14 years, TB lymph node in 15-59 years and malignancy among the C60 years age group. Jugulo-omohyoid (level III) and Supraclavicular (level VB) groups of Lymph nodes were found significantly more involved by malignancy whereas Jugulo-diagastric (level II), Post-auricular, Submandibular groups (level IB) were more commonly involved in TB. Malignancy patients presented late in respect to the tuberculosis patients. Knowledge about clinico-demographic perspectives of cervical lymphadenopathy in respect to their cytopathological diagnosis will help care giver practioners to detect/refer the respective cases early for investigations and treatment.

Objective:Different additives have been used to prolong brachial plexus block. We evaluated the effect of adding magnesium sulfate to ropivacaine for supraclavicular brachial plexus blockade. The primary endpoints were the onset and duration of sensory and motor block and duration of analgesia.Methods:One hundred patients (25–55 years) posted for elective forearm and hand surgeries under supraclavicular brachial plexus block were divided into two equal groups (Groups RM and RN) in a randomized, double-blind fashion. In group RM (n = 50), 30 ml 0.5% ropivacaine plus 150 mg (in 1 ml 0.9% saline) magnesium sulfate and in group RN (n = 50), 30 ml 0.5% ropivacaine plus 1 ml normal saline were administered in supraclavicular block. Sensory and motor block onset times and block durations, time to first analgesic use, total analgesic need, postoperative visual analog scale (VAS), hemodynamic variables, and side effects were recorded for each patient.Findings:Though with similar demographic profile and block (sensory and motor) onset time, the sensory and motor block duration and time to first analgesic use were significantly longer and the total need for rescue analgesics was lower in group RM (P = 0.026) than group RN. Postoperative VAS values at 24 h were significantly lower in group RM (P = 0.045). Intraoperative hemodynamics was comparable among two groups and no appreciable side effect was noted throughout the study period.Conclusion:It can be concluded from this study that adding magnesium sulfate to supraclavicular brachial plexus block may increase the sensory and motor block duration and time to first analgesic use, and decrease total analgesic needs, with no side effects.
