Xerosis meter-an electro-physiological device for quick screening of dry eyes
Y Gupta,M Gupta,R Maheshwari,T Mittal
Nepalese Journal of Ophthalmology , 2009, DOI: 10.3126/nepjoph.v1i2.3687
Abstract: Aim: To study the role of ‘Xerosis Meter' in screening of dry eye cases in a large population and compare its results with Schirmer's test and tear break-up time. Materials and method: In a cross sectional study with a control group dry eye was evaluated with Xerosis Meter, Schirmer test and tear film break-up time (TBUT). Cases included in the study were divided into two groups. Group I (Control Group) comprised of asymptomatic patients while Group II (Test Group) had patients showing symptoms and signs of dry eye. The Group II was further divided into two subgroups. Group IIa had cases showing positive result with either of the two tests Schirmer test or TBUT. Group IIb had cases which showed positive results with Xerosis Meter but normal results with the other two tests. Statistics: All the observations were statistically analyzed using SPSS version 11.5 software. The results obtained were compared statistically using unpaired t-test and chi-square test. The p value of < 0.05 was considered as significant. Results: There was a statistically significant difference between the means of Xerosis Meter, Schirmer test and TBUT of the two groups: Group I and Group IIa (p value < 0.001). On comparing Group I and Group IIb the difference was found to be statistically significant with Xerosis Meter (p value < 0.001). The sensitivity and specificity of Xerosis Meter were 85.7% and 80.2% respectively. This was higher than that of the Schirmer's test (81.3% and 74.9%) and TBUT (73.2% and 68.7%). Conclusion: The " Xerosis Meter" is an effective alternate in screening of dry eye cases. It is more effective than the TBUT and as effective as the Schirmer's test in detecting both the normal and dry eye patients. DOI: 10.3126/nepjoph.v1i2.3687 Nep J Oph 2009;1(2):123-128

Brazilian Journal of Microbiology , 2002, DOI: 10.1590/S1517-83822002000400010
Abstract: this work aimed to study, comparatively, the flocculation of fluorite particles with corynebacterium xerosis cells and three commercial long chain polymers. best flocculation results were obtained with cells of c. xerosis and with an anionic polyacrylamide. both were effective in solids removal and water clarification, although flocculation with c. xerosis cells requires a higher dosage of reagent per mass unit of processed ore.

Abstract: the treatment of fine particles dispersed in liquids is common in several industries and especially important in mineral processing. the efficiency of settling operations can be substantially increased by flocculation. the aim of this work was to study the flocculation of fine fluorite particles by the bacterium corynebacterium xerosis. flocculation tests, microelectrophoresis measurements and optical microscopy were used to evaluate flocculation. the results showed that c. xerosis cells adhere to the fluorite surfaces promoting the aggregation of the particles. high quality flocs can be obtained rapidly at ph 7.0 using a cell concentration of 40 mg/l, considerably lower than previously reported in the literature. the results are discussed with reference to the surface characteristics of the mineral and of the microorganism.

Indian Journal of Dermatology, Venereology and Leprology , 1997,
Abstract: A total of 32 patients with HIV infection were examined for cutaneous manifestations from September 1994 to December 1995 in the Dermatology and Venereology Department of Wenlock District Hospital, Mangalore. Xerosis was the commonest skin manifestation (50%). Oropharyngeal candidiasis was an indicator of grave prognosis in 4 patients. Seborrhoeic dermatitis, seen is in 15.6%, presented in an atypical, extensive and rapidly evolving form. Infections were atypical, extensive and did not respond to conventional modalities of treatment.

Abstract: Background Xerosis is a common skin disorder frequently observed in diabetic patients. An effective hydration of foot skin in diabetics is a relevant preventive strategy in order to maintain a healthy foot. Urea is considered an effective hydrating and emollient topical product. The aim of the present study was to evaluate the efficacy of topical urea 5% with arginine and carnosine (Ureadin Rx Db, ISDIN Spain) (UC) in comparison with glycerol-based emollient topical product (Dexeryl, Pierre Fabre) (EC), in Type 2 diabetic patients. Methods We assessed the effect of UC on skin hydration in a randomized, evaluator-blinded comparative study in 40 type II diabetic patients, aged 40–75 years, treated with UC or the comparator for 28 days with a twice-daily application. The principal outcomes were the Dryness Area Severity Index (DASI) Score and the Visual Analogue Score (VAS) for skin dryness evaluated at baseline and at the end of study period by an investigator unaware of treatment allocation. Results UC induced significantly greater hydration than EC with an 89% reduction in DASI score (from 1.6 to 0.2; p < 0.001) in comparison with baseline values. After 4 weeks, compared with the control group, DASI score in UC treated group was significantly lower (0.2 vs. 1.0; p = 0.048). VAS score (high values mean better hydration) significantly increased in both groups during treatment. VAS score at the end of treatment period was significantly higher in UC group in comparison with EC group (9.8 vs. 8.2; p = 0.05). Conclusion Application of urea 5%, arginine and carnosine cream increases skin hydration and alleviates the condition of skin dryness in Type 2 diabetic patients in comparison with a control glycerol-based emollient product.

Abstract: We have clinically examined 100 patients affected by cancer, determining type, frequency, treatment, and evolution of side effects related to chemotherapy.The prevalent cutaneous side effects in patients undergoing chemotherapy are skin rash, xerosis, pruritus, paronychia, hair abnormality, and mucositis. The clinical cases are reported in detail.Oncological therapies have become more selective and have low systemic toxicity because of their high specificity, but cutaneous side effects are common and may worsen the quality of life of these patients.

Indian Journal of Ophthalmology , 2008,
Abstract: A 50-year-old male who presented with bilateral keratomalacia and on subsequent evaluation was found to be human immunodeficiency virus (HIV) positive is being reported. A MEDLINE search of the literature did not reveal any report of keratomalacia as the initial presenting feature of HIV/ acquired immune deficiency syndrome.

Abstract: Introduction: Ocular morbid conditions are responsible for partial or total blindness. Ocular morbidities by its sheer magnitude form an enormous problem, not only in human suffering, but also in terms of economical loss and social burden. Aim: The aim of present study was to find the prevalence of ocular morbidities in rural area. Methods: Community based cross-sectional study in area covered by Rural Health Training Centre (RHTC), Hingna which is under the administrative control of Department of Preventive and Social Medicine, Indira Gandhi Government Medical College [IGGMC], Nagpur, was carried out in 194 families with 925 study subjects during February 2005-December 2005. The study focuses on ocular examination and diagnosis of ocular morbid conditions. Both eyes were examined and all the relevant clinical findings were recorded in predesigned proforma. Chi Square test was used for the analysis of data .Results: The results revealed that out of 925 study subjects 297(32.11%) were had ocular morbidity. Common ocular morbidity was Myopia (13.62%), Conjunctival xerosis (12.11%), Hypermetropia (11.68%), Xerophthalmia (3.46%), Pterygium (2.92%), immature senile cataract (2.70%), Eye strain (2.49%), mature senile cataract (1.84%) and Presbyopia (0.86%). Females were more affected (36.58%) as compared to males (28.37%), [χ2 = 7.09; d.f. =1, P< 0.05]. It was observed that as the age increases the prevalence of ocular morbidity increases [χ2=318.03; d.f =7, p<0.001].Higher prevalence of ocular morbid conditions was found in Illiterates 122 (40.94%) [χ2 = 16.47; d.f. =3, p<0.001] Conclusion: High prevalence of ocular morbidities was found in rural areas of central India with greater predominance among women and illiterates.
