Introduction:Vernal keratoconjunctivitis(VKC) is a chronic, recurrent, inammatory disease of ocular surface showing seasonal exacerbation, affecting young children. Topical steroids are the mainstay in the treatment of ocular allergy, but their use should be judicious since they carry serious side effects . Loteprednol and uorometholone carry better safety prole. Present study was conducted with the aim of comparing the efcacy of these two widely used steroids.Objectives:To compare total subjective symptom score (TSSS), total objective sign score (TOSS) and side effects of medications before and after treatment at each visit.Materials & Methods:A prospective randomised controlled study was performed on 92 patients of VKC over four weeks. Patients were allotted to either of the two arms of treatment (i.e. LP 0.5% or FML 0.1%). Subjective and objective assessments of the signs and symptoms of VKC were done using standard scoring methodologies at 7, 14, 21 and 28 days post treatment. The main outcome measure was measured in terms of TSSS and TOSS before and after treatment at each visit. Secondary outcomes included side effects. Statistical analysis of the data collected was carried out.Results: Loteprednol showed greater reduction in symptoms initially but by the end of study there was no statistically signicant difference in effect between the two drugs.Conclusions: Final improvement in clinical features and safety prole, at the end of 4 weeks was similar in eyes treated with either of the two drugs. Hence, both the drugs can be safely used in the treatment of VKC.

Background. Vernal keratoconjunctivitis (VKC) is a rare ocular surface inflammatory disease that affects mainly boys in the first decade of life. Clinical observations show that it generally regresses spontaneously with the onset of puberty, but therapeutic measures must be taken before then to control the course of the disease. Purpose.To evaluate the role of the lacrimal mucous component in VKC patients and compare tear ferning test (TFT) modifications, MUC5AC levels in tears, and density of conjunctival goblet cells to clinical characteristics before and after treatment with cyclosporine A (CY) in eye drops. Methods. Forty-seven patients affected by VKC and 30 healthy subjects aged between 3 and 16 years of life were enrolled. All individuals were submitted to complete eye examination and skin prick test (SPT) for the most common allergens. Then, they were subjected to collection of the tears and to impression cytology to evaluate TFT, MUC5AC levels, and conjunctival goblet cell density, before and after treatment with CY in eye drops. Results. Comparing the VKC group vs. the control group at baseline, a significant alteration in the degree of the ferns was found, indicating a pathological condition of the lacrimal mucous layer. In addition, an increased number of goblet cells were observed in the patients. The concentration of lacrimal secretory mucins (MUC5AC) did not show significant differences between the 2 groups. Patients treated with CY have reported improvements of some signs and symptoms of disease activity, including TFT, and a tendency of conjunctival goblet cell density to normalise. Conclusions. The results obtained demonstrated for the first time a significant alteration of the lacrimal mucin component evaluated in the VKC group, and an improvement of the latter after CY therapy.

Aim: To determine the effectiveness of supratarsal triamcinolone injection versus dexamethasone in recalcitrant vernal keratoconjunctivitis. Study Design: Prospective/randomized study Place and Duration of Study: Department of Ophthalmology, Lorallai Medical College, Loralai from 1st October 2020 to 31st March 2021. Methods: Fifty patients (100 eyes) of both genders and age between 12-40 years were enrolled. Detailed demographics of enrolled cases age, sex and body mass index were recorded after taking informed written consent. All patients had recalcitrant vernal keratoconjunctivitis. Patients were equally divided into 2-groups. Group I had 25 patients and received 20mg of supratarsal triamcinolone injection in both eyes and group II with 25 patients received 2mg of dexamethasone in their eyes. Postoperative effectiveness, complications and recurrence of disease was observed and compared among both groups. Results: There were 15 (60%) males and 10 (40%) females in group I with mean age 18.14±6.34 years while in group II, 15 (60%) males and 10 (40%) females with mean age was 17.68±4.54 years. Palprebral vernal keratoconjunctivitis was found in 36 eyes (10 patients of group I and 8 patients of group II) and Mixed vernal keratoconjunctivitis in 64 eyes (15 patients of group I and 17 patients of group II). Symptoms were itching,photophobia, lacrimation and pain. Conjunctival hyperemia, giant papillae and limbal infiltrate were the most common signs observed. Post operatively effectiveness among group I and II was (100% vs 92%) without any complication. Recurrence rate of vernal keratoconjunctivitis in group I was lower 4% as compared to group II 10%. Conclusion: The use of supratarsal triamcinolone injection in patients of recalcitrant vernal keratoconjunctivitis was effective and safest method as compared to dexamethasone in terms of less recurrence and high rate of efficacy.

Tool materials used in ultramicrotomy are glass, developed by Latta and Hartmann (1) and diamond, introduced by Fernandez-Moran (2). While diamonds produce more good sections per knife edge than glass, they are expensive; require careful mounting and handling; and are time consuming to clean before and after usage, purchase from vendors (3-6 months waiting time), and regrind. Glass offers an easily accessible, inexpensive material ($0.04 per knife) with very high compressive strength (3) that can be employed in microtomy of metals (4) as well as biological materials. When the orthogonal machining process is being studied, glass offers additional advantages. Sections of metal or plastic can be dried down on the rake face, coated with Au-Pd, and examined directly in the SEM with no additional handling (5). Figure 1 shows aluminum chips microtomed with a 75° glass knife at a cutting speed of 1 mm/sec with a depth of cut of 1000 Å lying on the rake face of the knife.

Phosgene still plays an important role as a toxic substance in the chemical industry. Thiess (1968) recently reported observations on numerous cases of phosgene poisoning. A serious difficulty in the clinical handling of phosgene poisoning cases is a relatively long latent period, up to 12 hours, with no obvious signs of severity. At about 12 hours heavy lung edema appears suddenly, however changes can be seen in routine X-rays taken after only a few hours' exposure (Diller et al., 1969). This study was undertaken to correlate these early changes seen by the roengenologist with morphological alterations in the lungs seen in the'light and electron microscopes.Forty-two adult male and female Beagle dogs were selected for these exposure experiments. Treated animals were exposed to 94.5-107-5 ppm phosgene for 10 min. in a 15 m3 chamber. Roentgenograms were made of the thorax of each animal before and after exposure, up to 24 hrs.
