Study of microbial growth on silicone tubes after transcanalicular laser-assisted dacryocystorhinostomy and correlation with patency

INTRODUCTION

Intubation in primary transcanalicular laser assisted dacryocystorhinostomy (TCLADCR) is performed to increase the success rates. However, the associated inflammation and infection can have adverse effects.

OBJECTIVE

To study the microbial infection and drug susceptibility of extubated silicone tubes and final anatomical patency in patients undergoing TCLADCR.

MATERIALS AND METHODS

A non-randomised prospective interventional study was conducted in a tertiary care eye centre. The study included twenty consecutive adult patients with primary nasolacrimal duct obstruction. They underwent TCLADCR with bicanalicular silicone intubation. The stents were removed at 2 months and subjected to culture sensitivity, followed by administration of appropriate antimicrobial agents. Main outcome measures studied were the microbial spectrum on the cultured tubes, their sensitivity profile and its correlation with final anatomical patency.

RESULTS

A positive culture was obtained in 100% cases, comprising of normal commensals and pathogenic organisms. Of the total 24 isolates, 16 (66.6%) Gram positive bacteria (75% Staphylococcus aureus) and 8 (33.3%) Gram negative bacteria (commonest E.coli) were found, with 4 tubes having more than one isolate. No fungal growth was seen. Ninety percent success rate was achieved at one year following appropriate antimicrobial therapy except in 2 patients with gram negative isolates who had failed to take the prescribed antibiotics following sensitivity reports. There was no correlation between multiple infections and success rate. However, by using the Fisher exact test, a positive correlation was obtained between appropriate antibiotic treatment and the final anatomical patency (p less than 0.05).

CONCLUSION

Silicone intubation predisposes to microbial growth, which if neglected, can lead to failure of TCLADCR.

Coping and caregiving experience of parents of children and adolescents with type-1 diabetes: An exploratory study

Aims:

To assess the coping strategies and the relationship of coping with subjective burden and positive caregiving consequences as perceived by the caregivers of children and adolescents with Type-1 diabetes.

Design:

Cross-sectional assessment.

Setting:

Outpatient of Endocrinology Department.

Participants:

Forty-one parents of children and adolescents with Type-1 diabetes

Main Outcome Measure:

Ways of coping checklist (WCC), involvement evaluation questionnaire (IEQ) and scale for assessment of positive aspects of caregiving experience (scale for positive aspects of caregiving experience) to study the coping, burden and positive aspects of caregiving respectively.

Results:

On WCC, the highest score was obtained for seeking social support, followed by planful problem-solving. More frequent use of coping strategies of confrontation and escape-avoidance was associated with significantly higher score on the tension domain of IEQ. Those who more frequently used problem-solving and distancing had significantly higher scores on worrying-urging-I domain of IEQ. supervision domain of IEQ was associated with more frequent use of confrontation, self-control, social support, escape-avoidance and positive reappraisal. More frequent use of distancing and problem-solving were associated with lower caregiving personal gains. More frequent use of problem-solving was associated with higher caregiver satisfaction and lower scores in the domain of self-esteem and social aspects of caring.

Conclusion:

Caregivers of patients with Type-1 diabetes predominantly use adaptive coping strategies. Higher use of certain coping strategies is associated with negative and positive caregiving consequences.

Acute kidney injury associated with ingestion of star fruit: Acute oxalate nephropathy

Starfruit (Averrhoa carambola) and its juice are popular in the Indian subcontinent as an indigenous medicine. Oxalate concentration in this fruit and it's freshly prepared juice is very high. We present a report of patients presenting with acute kidney injury due to oxalate nephropathy admitted in a single center. All patients had history of ingesting star fruit. Patients became symptomatic after 10-12 h of eating and main symptoms were pain abdomen and decrease in urine output. Three patients needed hemodialysis. All improved with complete renal recovery. Taking star fruit in large amount on an empty stomach and in a dehydrated state is a risk factor for nephrotoxicity.

Management of bilateral microspherophakia with secondary angle closure glaucoma

BACKGROUND

Microspherophakia is characterized by lenticular myopia, late development of lens dislocation, shallow anterior chamber and angle-closure glaucoma. If it is associated with angle closure glaucoma, the management can be challenging.

OBJECTIVE

To report the management of a case of bilateral secondary angle closure glaucoma with isolated microspherophakia and right subluxated lens in a middle aged lady.

CASE

A 47-year-old female presented with bilateral secondary angle closure glaucoma with isolated microspherophakia, right subluxated lens and left operated trabeculectomy. The patient`s best corrected log mar visual acuity improved from 1.0 to 0.2 and intraocular pressure (IOP) decreased from 24.9mm of Hg to lower teens following lensectomy with scleral fixation of posterior chamber intraocular lens in the right eye. The left eye IOP remained in mid teens without medication in two year follow up.

CONCLUSION

This case demonstrates that microspherophakia should be ruled out even in middle aged patients presenting as angle closure glaucoma. The possibility of thickened cornea must be kept in mind requiring an IOP correction. Lensectomy with scleral fixation of posterior chamber IOL provides a satisfactory recovery of visual acuity and IOP control. Though in this patient, the lens was held in position by posterior synechiae in the left eye, future stability of zonules needs to be monitored.

Dermatopathia Pigmentosa Reticularis with Salzmann's nodular degeneration of cornea: A rare association

BACKGROUND

Dermatopathia pigmentosa reticularis (DPR) is a very rare autosomal dominant disorder with the diagnostic triad of generalized reticulate hyperpigmentation, noncicatricial alopecia and onychodystrophy.

OBJECTIVE

To describe the occurrence of Salzmann's nodular degeneration of cornea with moderate dry eye in a patient with Dermatopathia pigmentosa reticularis.

CASE

We present an 11 year old young Indian girl with DPR who had Salzmann's nodular degeneration of cornea with moderate dry eye. She was put on symptomatic treatment and counseled regarding the course of disease, familial nature and avoidance of exposure to sun.

CONCLUSION

In a patient of Salzmann`s nodular degeneration with generalized reticulate hyperpigmentation, noncicatricial alopecia and onychodystrophy the diagnosis of DPR must be kept in mind. A multidisciplinary approach is required for the management of such cases.

Effects of five days of bed rest with intermittent centrifugation on neurovestibular function

OBJECTIVES

We tested whether intermittent short-radius centrifugation was effective for mitigating alteration in balance and gait following bed rest.

METHODS

Ten male subjects were exposed to 5 days of 6° head-down tilt bed rest with: (a) no countermeasure; (b) daily 1-g centrifugation for a continuous 30-min period; and (c) daily 1-g centrifugation for six periods of 5 min. During and after the bed rest, subjects were asked to scale the severity of neurovestibular symptoms that followed centrifugation or 80° head-up tilt. Following the bed rest, equilibrium scores were derived from anterior-posterior sway while standing on a foam pad with the eyes open or closed while making pitch head movements, and gait was evaluated by grading subjects' performance during various locomotion tasks.

RESULTS

At the beginning of bed rest, one single 30-min period of centrifugation induced more severe neurovestibular symptoms than six periods of 5-min centrifugation. After bed rest, although equilibrium scores and gait performance were not significantly altered, subjects felt less neurovestibular dysfunction with orthostatic stress when centrifugation was used.

CONCLUSION

Centrifugation was effective at reducing the severity of neurovestibular symptoms after bed rest, but this decrease was not different between one or multiple daily sessions.

Brief advice on alcohol: as easy as A...B...I?

Alcohol is widely consumed by the majority of the UK population and alcohol-related harm is estimated to cost society £21 billion per year in healthcare, lost productivity costs, crime and antisocial behaviour. The dental setting offers an ideal opportunity to screen for harmful alcohol consumption; however, current emphasis is on the management of acute complications and risk associated in treating patients with excessive alcohol intake rather than screening and patient education. This article outlines ways in which dentists could improve their recognition of 'at risk' patients and then offer practical advice to help reduce the harmful effects of alcohol.

Computer evaluation of hidden potential of phytochemicals of medicinal plants of the traditional indian ayurvedic medicine

Applicability of our computer programs PASS and PharmaExpert to prediction of biological activity spectra of rather complex and structurally diverse phytocomponents of medicinal plants, both separately and in combinations has been evaluated. The web-resource on phytochemicals of 50 medicinal plants used in Ayurveda was created for the study of hidden therapeutic potential of Traditional Indian Medicine (TIM) (http://ayurveda.pharmaexpert.ru). It contains information on 50 medicinal plants, their using in TIM and their pharmacology activities, also as 1906 phytocomponents. PASS training set was updated by addition of information about 946 natural compounds; then the training procedure and validation were performed, to estimate the quality of PASS prediction. It was shown that the difference between the average accuracy of prediction obtained in leave-5%-out cross-validation (94,467%) and in leave-one-out cross-validation (94,605%) is very small. These results showed high predictive ability of the program. Results of biological activity spectra prediction for all phytocomponents included in our database are in good correspondence with the experimental data. Additional kinds of biological activity predicted with high probability provide the information about most promising directions of further studies. The analysis of prediction results of sets of phytocomponents in each of 50 medicinal plants was made by PharmaExpert software. Based on this analysis, we found that the combination of phytocomponents from Passiflora incarnata may exhibit nootropic, anticonvulsant and antidepressant effects. Experiments carried out in mice models confirmed the predicted effects of Passiflora incarnata extracts.

Cervical epidural anaesthesia with ropivacaine for modified radical mastectomy

BACKGROUND

Cervical epidural anaesthesia (CEA) using local anesthetics (LA) is a well established technique for the surgeries in the neck, chest and upper arms. Recently ropivacaine is introduced with better safety profile.

OBJECTIVES

The aim was to observe the safety of Cervical epidural anaesthesia as an anaesthetic technique and to compare the efficacy of epidural 0.25% bupivacaine with 0.375% ropivacaine for radical mastectomies.

METHODS

A double blind study was conducted on 40 ASA grade I / II females who received CEA with 10 ml of 0.25% of bupivacaine +25μg of fentanyl in group B (n=20) and 10 ml of 0.375% of ropivacaine +25μg of fentanyl in group R (n=20) epidurally. Assessment of the block, vital monitoring and complications noted.

RESULTS

No significant differences observed in the onset of sensory block (5.05 min and 5.4 min in group B and R respectively, P>0.05).The mean motor blockade score, time to achieve complete blockade and time to grade I motor recovery was significantly longer in group B (2.3, 22.5 and 79.5 minutes respectively) as compared to group R (1.5, 18.3 and 66.3 minutes respectively, P<0.05). Respiratory distress developed in two patients of group B that required general anaesthesia (GA) with intubation.

CONCLUSION

Use of 0.37% ropivacaine is safer than 0.25% bupivacaine for CEA for radical mastectomy. It provides good surgical anaesthesia with lesser degree of motor blockade and the respiratory effects.

Agriculture related corneal injuries

INTRODUCTION

Agricultural workers are predisposed to corneal injuries, which, if neglected, can lead to corneal blindness.

OBJECTIVE

To study the prevalence and mode of agriculturerelated corneal injuries in the village of Badkali, MuzaffarNagar, Western Uttar Pradesh, India in 2005 - 2006.

SUBJECTS AND METHODS

Adult population of village Badkali, MuzaffarNagar, Uttar Pradesh. A door-to-door survey was carried out by paramedical ophthalmic assistants in October and November 2007. The main outcome measure was occurrence of corneal trauma in the fields from January 2005 until December 2006, its mode of injury, symptoms, treatment taken and outcome.

RESULTS

The study area comprised of 718 people, of whom 584 were engaged in agricultural activities and 481 were male. While working on the fields, 221 persons sustained corneal injuries and out of them four were injured more than once. The number of injuries caused due to sugarcane leaves, wheat , cattle tail/ ear, 'cheri leaves' and others were 83(36.7 %), 24(10.6 %), 60(25.5 %), 31(13.7 % )and 28(12.4 %) respectively. All were closed globe injuries except for two. Out of the 221 injured, 117 (51.7 %) took treatment and 95(42.2 %) had a best corrected visual acuity less than 6/18.

CONCLUSION

The majority of the population in Badkali were employed in farming. Logistic regression shows that the occurrence of injuries was more in those engaged in farming and related activities as compared to other occupations (OR = 0.012, p = 0.000, 95 % CI = 0.02, 0.09) and the maximum number of injuries being caused by sugar cane leaves followed by cattle tails.
