Do Commonly Used Functional Outcome Measures Capture Activities that Are Relevant for People with Stroke in India?

Objectives: In India, post-stroke outcomes are determined using functional outcome measures (FOMs), the contents of which have not been validated for their relevance to the Indian population. In this study, we aimed to evaluate the cultural validity of five frequently used stroke-specific FOMs by comparing their contents with the problems reported by patients with stroke in India.

Methods: Face-to-face structured interviews were conducted with 152 patients diagnosed with stroke in India. Problems and goals identified by the patients were compared to each item included in the FOMs used in stroke rehabilitation.

Results: The Stroke Impact Scale (SIS) and the Frenchay Activities Index (FAI) include items related to the most frequently identified problems. However, neither covers problems related to the need for squatting and sitting on the floor. Use of public transport and community walking are not included in the SIS. Leisure and recreational activities (e.g. gardening, reading books), cognitive and speech functions (e.g. memory, thinking) and bowel and bladder dysfunctions were the common items identified as “not a problem” or “not relevant” by the patients.

Discussion: Our findings suggest that the SIS and FAI are the most appropriate FOMs for patients with stroke in India as they include items related to the majority of problems identified by study participants. Many items on both measures, however, were identified as not a problem or not relevant. There is a need for developing culture-specific FOMs that incorporate all major concerns expressed by patients with stroke in India.     

Three-Dimensional Anorectal Manometry Enhances Diagnostic Gain by Detecting Sphincter Defects and Puborectalis Pressure

Digestive Diseases and Sciences - Constipation and fecal incontinence (FI) are common and are often evaluated with anorectal manometry. Three-dimensional high-resolution anorectal manometry (HRAM)...     

Port site infection in laparoscopic surgery: A review of its management

Laparoscopic surgery(LS), also termed minimal access surgery, has brought a paradigm shift in the approach to modern surgical care. Early postoperative recovery, less pain, improved aesthesis and early return to work have led to its popularity both amongst surgeons and patients. Its application has progressed from cholecystectomies and appendectomies to various other fields including gastrointestinal surgery, urology, gynecology and oncosurgery. However, LS has its own package of complications. Port site infection(PSI), although infrequent, is one of the bothersome complications which undermine the benefits of minimal invasive surgery. Not only does it add to the morbidity of the patient but also spoils the reputation of the surgeon. Despite the advances in the field of antimicrobial agents, sterilization techniques, surgical techniques, operating room ventilation, PSIs still prevail. The emergence of rapid growing atypical mycobacteria with multidrug resistance, which are the causative organism in most of the cases, has further compounded the problem. PSIs are preventable if appropriate measures are taken preoperatively, intraoperatively and postoperatively. PSIs can often be treated non-surgically, with early identification and appropriate management. Macrolides, quinolones and aminoglycosides antibiotics do show promising activity against the atypical mycobacteria. This review article highlights the clinical burden, presentations and management of PSIs in LS as shared by various authors in the literature. We have given emphasis to atypical mycobacteria, which are emerging as a common etiological agent for PSIs in LS. Although the existing literature lacks consensus regarding PSI management, the complication can be best avoided by strictly abiding by the commandments of sterilization techniques of the laparoscopic instruments with appropriate sterilizing agent.     

Susceptibility of Candida albicans and Enterococcus faecalis to Chitosan,Chlorhexidine gluconate and their combination in vitro

The aim of the present study was to analyse the sustain release of Chlorhexidine with Chitosan and to investigate the antimicrobial activity of 2% Chlorhexidine gel, 2% Chitosan gel and their combination against Candida albicans and Enterococcus faecalis. Sustain release of Chlorhexidine with Chitosan was determined using UV spectrophotometer. Then the inoculae of these organisms were used to make the lawn culture on sabouraud's dextrose agar and blood agar plates. Wells were prepared in these lawn cultures and filled with 2% Chlorhexidine gel, 2% Chitosan gel and their combination. The agar plates were incubated overnight at 37°C and the zone of inhibition was examined after 48 h. Release of Chlorhexidine with Chitosan was better than plain Chlorhexidine release. Combination of Chlorhexidine and Chitosan showed maximum inhibitory zone for C. albicans (25.2 mm) and E. faecalis (26.0 mm). Plain Chlorhexidine gel showed intermediate inhibitory zone for C. albicans (20.6 mm) and E. faecalis (21.4 mm) and plain Chitosan gel showed minimum inhibitory zone for C. albicans (16.6 mm) and E. faecalis (11.0 mm). Carbopol which served as control did not have any antimicrobial effect. The present study suggests that 2% Chlorhexidine gel in combination with 2% Chitosan gel has the highest antimicrobial effect against C. albicans and E. faecalis compared with 2% Chlorhexidine gel or 2% Chitosan gel alone.     

A case series and review of sporotrichosis in Sikkim

Sporotrichosis caused by the fungus Sporothrix schenckii has been widely reported from the northern Himalayan belt and the north eastern region of India. Three autochthonous cases of lymphocutaneous sporotrichosis from east and south districts of Sikkim are reported. Fluid aspirate from the nodulo-ulcerative lesions were sent for cytology and fungal culture. S. schenckii was isolated on culture and cytological examination in all three cases showed granulomatous reaction. Thermal dimorphism was demonstrated and animal pathogenicity testing was performed. Saturated solution of potassium iodide was used for treatment and the last case was treated with itraconazole and potassium iodide. Awareness of this disease and an extensive environmental study is required to understand the actual burden of this disease.     

Comparative evaluation of humic substances in oral drug delivery

Major and biologically most explored components of natural organic matter (NOM) are humic acid (HA) and fulvic acid (FA). We have explored rock shilajit as a source of NOM. On the other hand carbamazepine (CBZ) is a well known anticonvulsant drug and has a limited accessibility to brain. Bioavailability and pharmacokinetic profiles of CBZ have been improved by complexation and different techniques also.Present study has assessed the comparative abilities of FA and HA as complexing agent for CBZ in order to enhance pharmacokinetic profile of CBZ and accessibility to the brain. These two complexing agents have been compared on various indices such as their abilities to cause complexation and enhance solubility, permeability and dissolution. The present study also compared pharmacodynamic and biochemical profiles after oral administration of complexes. With the help of various pharmaceutical techniques such as freeze drying, physical mixture, kneading and solvent evaporation, two molar ratios (1:1 and 1:2) were selected for complexation and evaluated for conformational analysis (molecular modeling). Complex formed was further characterized by differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FT-IR), mass spectroscopy and X-ray diffraction (XRD).Preclinical study on rodents with CBZ–HA and CBZ–FA has yielded appreciable results in terms of their anticonvulsant and antioxidants activities. However, CBZ–HA (1:2) demonstrated better result than any other complex.
