Rehydration with sodium-enriched coconut water after exercise-induced dehydration

Ismail I, Singh R, Sirisinghe RG

Southeast Asian J. Trop. Med. Public Health, 2007 Jul;38(4):769-85.
PMID: 17883020

This crossover study assessed the effectiveness of plain water (PW), sports drink (SD), fresh young coconut water (CW) and sodium-enriched fresh young coconut water (SCW) on whole body rehydration (R) and plasma volume (PV) restoration after exercise-induced dehydration. Ten healthy male subjects ran at 65% of VO2max in an environmental temperature of 32.06 +/- 0.02 degree C with a relative humidity (rh) of 53.32 +/- 0.17% for 90 minutes to lose 3% body weight (BW). During the 2-hour rehydration period, subjects drank, in randomized order, PW, SD, CW or SCW equivalent to 120% of BW lost in three boluses representing 50, 40 and 30% of the fluid lost at 0, 30, and 60 minutes, respectively. In all trials subjects were still somewhat dehydrated even after the 2-hour rehydration period. Indexes of percent rehydration with PW, SD, CW and SCW were 58 +/- 2, 68 +/- 2, 65+/- 2 and 69 +/- 1%, respectively, with significantly better rehydration with SD and SCW. The rehydration indexes for SD and SCW were significantly lower than PW (p < 0.01). PV was restored to euhydration levels after 2 hours of rehydration with SD, CW and SCW but not with PW. The plasma glucose concentration were significantly higher when SD, CW and SCW were ingested. SCW was similar in sweetness to CW and SD but caused less nausea and stomach upset compared to SD and PW. In conclusion, ingesting SCW was as good as ingesting a commercial sports drink for whole body rehydration after exercise-induced dehydration but with better fluid tolerance.

Fulltext Rice starch low sodium oral rehydration solution (ORS) in infantile diarrhoea

Iyngkaran N, Yadav M

Med J Malaysia, 1995 Jun;50(2):141-4.
PMID: 7565183

The relative efficacy and incidence of hypernatremia of a rice starch based low sodium (sodium of 60 mmol/L) oral electrolyte solution was compared to the standard WHO oral rehydration solution (ORS; sodium 90 mmol/L) in 60 infants with non choleragenic acute diarrhoea. Both solutions were found to be equally effective in correcting dehydration as determined by the respective post hydration weight gain which was 150 +/- 175 gms in the rice starch low sodium ORS group and 164 +/- 125 gms in the standard WHO ORS group. However, the mean frequency of stools was greater and the duration of stay longer in the WHO ORS group compared to the rice starch low sodium group. There were 5 cases of hypernatremia in the WHO ORS group as opposed to only one in the rice starch low sodium ORS group. The present study shows that a rice starch low sodium ORS was as effective as the standard WHO ORS and had a lower incidence of hypernatremia in the fluid and electrolyte management of infants with non choleragenic diarrhoea.

Fulltext Prevention of Esophageal Strictures After Endoscopic Submucosal Dissection: A Promising Therapy Using Carboxymethyl Cellulose Sheets

Lua GW, Tang J, Liu F, Li ZS

Dig Dis Sci, 2016 06;61(6):1763-9.
PMID: 26809870 DOI: 10.1007/s10620-016-4034-4

BACKGROUND: Esophageal stricture is one of the serious adverse events following endoscopic submucosal dissection (ESD). However, optimum preventive techniques are still lacking.
AIMS: Our primary objective was to evaluate the incidence of post-ESD esophageal stricture with the application of carboxymethyl cellulose (CMC) sheets. Secondary objectives were to determine the number of sessions of endoscopic balloon dilatation (EBD) required to resolve post-ESD strictures and the incidence rate of peri-operative adverse events.
METHODS: This was a pilot, single-center, prospective study. Seven patients who had high risks of developing post-ESD esophageal stricture were enrolled into our study. CMC sheets were applied to the mucosal defects immediately after the completion of ESD. Patients were monitored and reviewed after ESD to detect any adverse events.
RESULTS: The incidence rate of post-operative stricture was 57 % (4/7 patients). Among patients who required EBD, the number of sessions performed was 2.8 ± 2.2. No serious post-operative adverse events were reported.
CONCLUSION: The use of CMC sheets appears to be a safe and effective prophylactic treatment for esophageal stricture following extensive ESD.

To investigate the suitability of an SCMC (sodium carboxymethyl cellulose/polyethylene glycol 400/carbopol 934P) and an HPMC (hydroxypropylmethyl cellulose/polyethylene glycol 400/carbopol 934P) films as drug vehicle for buccal delivery.

Sodium carboxymethylcellulose scaffolds and their physicochemical effects on partial thickness wound healing

Ramli NA, Wong TW

Int J Pharm, 2011 Jan 17;403(1-2):73-82.
PMID: 20974238 DOI: 10.1016/j.ijpharm.2010.10.023

This study investigated critical physicochemical attributes of low (LV), medium (MV) and high molecular weight (HV) sodium carboxymethylcellulose (SCMC) scaffolds in partial thickness wound healing. SCMC scaffolds were prepared by solvent-evaporation technique. Their in vitro erosion, moisture affinity, morphology, tensile strength, polymer molecular weight and carboxymethyl substitution, and in vivo wound healing profiles were determined. Inferring from rat wound size, re-epithelialization and histological profiles, wound healing progressed with HV scaffold>LV-MV scaffold>control with no scaffold. The transepidermal water loss (TEWL) from wound of rats treated by control>HV scaffold>LV-MV scaffold. HV scaffold had the highest tensile strength of all matrices and was resistant to erosion in simulated wound fluid. In spite of constituting small nanopores, it afforded a substantial TEWL than MV and LV scaffolds from wound across an intact matrix through its low moisture affinity characteristics. The HV scaffold can protect moisture loss without its excessive accumulation at wound bed which hindered re-epithelialization process. Regulation of transepidermal water movement and wound healing by scaffolds was governed by SCMC molecular weight instead of its carboxymethyl substitution degree or matrix pore size distribution, with large molecular weight HV preferred over lower molecular weight samples.

PMID: 9582679

A case of bullous pemphigoid with extra-oral and intraoral lesions in a 60-year-old female is reported. Diagnosis is based on histopathology and direct immunofluorescence, and the treatment regime described included oral prescription of prednisolone and topical application of a mixture of fluocinonide ointment and triamcinolone acetonide in Orabase on the oral lesions.
