ABSTRACT
Background: Ocular infections are a result of alteration in the normal microbial flora of eye. They are not only responsible for increase in morbidity varying from self-limiting trivial infection to sight threatening infection but also blindness.Methods: Patients with ocular infections were recruited at Regional Institute of Ophthalmology, Moti Lal Nehru Medical College, Allahabad, Uttar Pradesh. Bacterial profile in ocular infections and susceptibility pattern to commonly used antibiotics were analyzed amongst these patients. The isolated organism was then identified by colony morphology, gram stain and biochemical test following which in vitro susceptibility test was performed by Kirby-Bauer disc diffusion method and interpreted clinically.Results: Staphylococcus aureus and coagulase negative Streptococcus were most common etiological agents of ocular infections in the present study. It was observed that bacterial isolates were highly (in 100% of cases) susceptible to vancomycin and chloramphenicol among gram positive organisms. Gram negative organisms showed higher susceptibility to moxifloxacin, tobramycin and gentamycin. Pseudomonas was seen to have sensitivity towards ceftazidime and cefazolin.Conclusions: The present study gives an insight into use of ocular antimicrobials in northern India. These findings illustrate the need for constant bacterial surveillance before starting empirical treatment.
ABSTRACT
Background: Vernal keratoconjunctivitis (VKC) is a chronic allergic conjunctival disease. Immunomodulatory drugs like cyclosporine is being used for its treatment. Tacrolimus is another immunomodulator drug that can be used in VKC. This study was done to compare the efficacy of tacrolimus and cyclosporine in VKC.Methods: This prospective study was conducted on 60 patients of either sex by dividing them into two groups. The first group was treated with cyclosporine (0.05%) ophthalmic eye drop and second group with tacrolimus (0.03%) ophthalmic ointment. Total five objective signs (hyperaemia, oedema, papillae, corneal involvement and tantra’s dot) and five subjective symptoms (itching, tearing, foreign body sensation, discharge and photophobia) data was collected and tabulated for statistical analysis.Results: Authors found TSSS in both groups decrease significantly (p <0.05 or p <0.01 or p <0.001) at all post periods as compared to respective predecessor periods except 4 weeks to 6 weeks in cyclosporine group and 6 weeks to 8 weeks in tacrolimus group. Similarly, for each period, on comparing the mean TSSS between the groups TSSS between the groups at all periods does not differed statistically though at final evaluation (mean change from baseline to 8 weeks), it improved 5.2% more in tacrolimus group (83.7%) than cyclosporine group (78.5%). Similarly, TOSS also decreased at all post periods except 4 weeks to 6 weeks, and 6 weeks to 8 weeks in cyclosporine group and 6 weeks to 8 weeks in tacrolimus group. Improvement in scores was 11.6% more in tacrolimus (81.6%) than cyclosporine (70.0%). Cyclosporine eye drops are associated with burning sensation and redness of eyes while transient ocular irritation was only observed side effect with tacrolimus.Conclusions: The study found tacrolimus is clinically better drug for treatment of vernal keratoconjunctivitis than cyclosporine and is also cost effective.
ABSTRACT
Efavirenz is the first line non-nucleoside reverse transcriptase inhibitor suggested by World Health Organization for newly diagnosed patients started on antiretroviral therapy. Dermatologic manifestations are the usual side effects associated with this drug. Authors hereby, present a case report of efavirenz induced drug hypersensitivity reported at a tertiary care hospital at Allahabad, Uttar Pradesh. The patient developed rashes and vomiting within a week of start of TLE regimen. Re-challenge test revealed confirmation of the adverse drug reaction by efavirenz. Change of the regimen was done for the patient following hospitalization for the event. This case report explains that strict pharmacovigilance is essential in the initial days of start of antiretroviral therapy. Further trials to improve the safety profile of the patients on ART are the need of the hour.
ABSTRACT
Background: Dry eye disease (DED) is the very common and underdiagnosed ocular condition affecting vision, quality of life, and the outcomes of cataract or refractive surgery. Dry eye disease (DED), either alone or in combination with other conditions, is a frequent cause of ocular irritation that leads the patients to seek ophthalmic care. Due to a wide variety of presenting symptoms, it is often unrecognized and this causes great frustration of the patient and treating physician. While these symptoms often improve with appropriate treatment, usually in majority of the cases the disease may not be curable. Aim of the study was to compare the efficacy of tacrolimus and cyclosporine in dry eye disease.Methods: This was a single centred, 3 months prospective study. Patients with unilateral or bilateral dry eye disease and an ocular surface disease index score >12, atleast one eye with schirmer score <5mm and TBUT <10 s were enrolled in the study. The enrolled patients were randomly divided into two groups, twenty-five patients in Group 1 and twenty three patients in Group 2 completed the follow up. Group 1(n =25) who received 0.03% tacrolimus eye ointment twice daily for consecutive 3 months and Group 2 (n= 23) received 0.05% cyclosporine eye drops twice daily for consecutive 3 months the primary efficacy outcome was Schirmer score after 3 months. The secondary outcomes were TBUT and adverse effects.Results: After 3 months, both the treatment groups showed significant improvement in mean Schirmer score (p<0.001) and mean TBUT (p <0.0001). However, on comparing both the groups, mean Schirmer score and mean TBUT, results were comparable. No patient discontinued treatment because of minor ocular adverse effects.Conclusions: Dry eye patients demonstrated improvement in Schirmer score and TBUT after 3 months of treatment with tacrolimus 0.03% ointment and cyclosporine 0.05% eye drops.
ABSTRACT
Background: Amla is one of the most often used herbs in indigenous medicine, whose all parts including fruit, seed, leaves, root, bark, and fl owers are used in various Ayurvedic/Unani medicines. However, studies to establish analgesic potential of amla were limited, so the purpose of the present study was to evaluate analgesic activity of amla, if it possesses any. Methods: Albino rats were divided randomly in three groups of six rats each. Group 1 (control) received distilled water orally, Group 2 (test) received Emblica offi cinalis extract in dose of 600 mg/kg orally and Group 3 (standard) received Pentazocine in dose 10 mg/kg intraperitoneally. Results: Emblica offi cinalis extract did not produced statistically signifi cant (p>0.05) analgesia when compared with the control group in hot plate latency, but produced a statistically signifi cant reduction in 6% NaCl induced abdominal writhing (p<0.05). Conclusions: Since the plant extract signifi cantly reduced the number of writhes in abdominal writhing model, but do not increase hot plate latency, the commercially available crude extract of Emblica offi cinalis exhibit analgesic activity involving peripheral mechanisms.
ABSTRACT
Pharmacology is the backbone of clinical discipline of medical science. In the computer era of advancement, paraclinical teachings become more technical and clinical oriented. Regarding to undergraduate practical’s the animal experimentation and dispensing pharmacy are only exercises. But these are matter of critics due to their non-utility in future. Student’s apathy and non-interest are hidden factor to perform such boring experiments. Meanwhile the old-dated exercises have no potential to tone-up adequate clinical skills in future study instead of wastage of time and money. Killing of innocent animals is crucial and should be socially discouraged. Thus Pharmacology practical are matter of debate in current scenario. Being attachment with past sentiment of traditional dispensing pharmacy and animal experimentations, they are difficult to delete completely. The present article highlights some of our efforts in undergraduate exercises.
ABSTRACT
Pharmacovigilance is a new discipline of pharmacology concerned with adverse drug reaction (ADR) monitoring. Being an emerging section, it gains widespread global popularity within a short span of time. Pediatrics is very special branch of medical science deals with innocent aspect of growing life. As most of their body physiology are varies in accordance to age, therefore ADRs detection needs special attention.
