Item Breathing comfort associated with different modes of ventilation: a comparative study in non-intubated healthy Nepalese volunteers.(2007-07-08) Baral, P R; Bhattarai, B; Pande, R; Bhadani, U; Bhattacharya, A; Tripathi, MOBJECTIVE: To compare subjective experience of comfort associated with various commonly used supportive modes of mechanical ventilation for weaning in the intensive care unit (ICU). SUBJECTS AND METHODS: The study was carried out in general ICU of a community-based teaching hospital in 30 healthy adult Nepalese volunteers of either sex and 19-37 years of age. The subjects were randomly made to experience breathing via anatomical facemask through ventilator circuit with synchronized intermittent mandatory ventilation (SIMV), assisted spontaneous breathing (ASB), biphasic positive airway pressure (BiPAP), and continuous positive airway pressure (CPAP) modes of ventilation with parameters set at intermediate level of respiratory support. Subjective comfort of breathing was noted using a 10 cm visual analogue scale (VAS) with no discomfort at one end and maximum imaginable discomfort at the other. Inspiratory and expiratory experience of discomfort was also noted using a four point ranking scale (0-no discomfort, 1-mild discomfort, 2-moderate discomfort and 3-severe discomfort). In addition, presence or absence of feeling of breathlessness and inflation was also noted. RESULTS: BiPAP was the most comfortable mode of ventilation (p<0.01) on visual analogue scale. SIMV and CPAP modes were associated with higher discomfort than other modes during inspiratory and expiratory phases respectively. Breathlessness and inflation were least felt in BiPAP and SIMV modes respectively. CONCLUSION: Perception of breathing comfort can vary widely with various supportive modes of ventilation in the ICU. Hence, no single supportive mode should be used in all patients during weaning from mechanical ventilation. Key words: assisted spontaneous breathing; biphasic positive airway pressure; breathing comfort; continuous positive airway pressure; mechanical ventilation; supportive modes synchronized intermittent mandatory ventilation; weaning.Item Immunoprofile of Hodgkin's lymphoma in India.(2008-04-16) Patkar, N; Mehta, J; Kulkarni, B; Pande, R; Advani, S; Borges, AAims and Background: The immunoprofile of the Reed Sternberg cell with respect to immunoreactivity for CD20 and lack of CD15 has been described as a poor prognostic factor. Large scale studies analyzing the immunoprofile of Hodgkin's lymphoma (HL) from India are lacking. The aim of this study was to obtain baseline information on relative frequencies and immunoprofiles of the two major types of HL and comparing reports from developed and developing countries. Materials and Methods: 451 cases of HL were classified as per the WHO into classical (n= 397) HL (cHL) and nodular lymphocyte predominant HL (NLPHL) (n=54). Cases of cHL were divided into 5 immunophenotypic groups; Group A (CD15+,CD30+,CD20-), Group B (CD15-,CD30+,CD20-), Group C (CD15+,CD30+,CD20+), Group D (CD15-,CD30+,CD20+)and Group E (CD15-,CD30-,CD20+). In cases of NLPHL, the immunophenotype of lymphocytes in the background, whether T(CD3) or B(CD20) rich was observed. Results: Most cases of cHL belonged to Group A (44.58%) followed by Group B (40.05%), C(5.54%), D(9.57%) and E(0.25%). Half, (50.89%) the cases of cHL were immunonegative for CD15, whereas CD20 was expressed by 15.61% of the cases. Three (5.55%) cases of NLPHL showed a CD3 (T) cell rich background. Significant differences were also observed with respect to the age distribution of cHL as compared to the west. Conclusion: Our study demonstrates that India has a high number of CD15 negative and a relatively higher number of CD20 positive cHL cases as compared to the western population. Favorable treatment response and good cure rates that one sees in western cHL may not apply to India.Item Percutaneous tracheostomy.(2003-01-11) Rao, B K; Pande, R; Sharma, S C; Ray, S; Lakshmi, B; Singh, V K; Gupta, R K; Suri, SThe purpose of this review is to discuss the various techniques of percutaneous tracheostomy and to assess their safety and efficacy profile, indications and contraindications, early and late complications. Literature was reviewed from Medline and MD Consult databases. Early techniques by Sheldon, toye and Schachner have been abandoned due to their high complication rates. Percutaneous dilational tracheostomy using the Ciaglia kit (Wiliam Cook Europe Bjaeverskov) and a Griggs kit (Portex PDT kit, POrtex, Hythe, Kent, UK) has been used most often. Griggs guide Wire Dilator Forceps kit (SIMS, Portex, Hythe, Kent, UK) is the next most common in use but its long-term studies are few. Fantoni (TLT set, Mallinckrodt Medical) and PercuTwist device (Riisch, Kernen, Germany) are two new techniques currently under study. Percutaneous dilational tracheostomy and conventional surgical tracheostomy are still competing methods to provide an airway for intensive care patient requiring assisted ventilation. Review of literature shows that percutaneous tracheostomy is safe, cost-effective and compares favourably with the open surgical tracheostomy. Many intensive care units now use the percutaneous tracheostomy as a procedure of choice. Percutaneous tracheostomy has a learning curve and requires appropriate case selection and meticulous attention to the technique by all those who want to use this method.Item Phase I tolerability study of Yogaraj-guggulu--a popular ayurvedic drug.(1984-04-01) Antarkar, D S; Pande, R; Athavale, A V; Shubhangi, R; Saoji, S R; Shah, K N; Jakhmola, A T; Vaidya, A BItem Serological identification and cross reactions of cow and buffalo milk with other body fluids.(1965-10-01) Pande, R; Pathak, R C
