A Study of Management of Primary Chalazion in Adults by Intralesional Injection of Triamcinolone Acetonide

Introduction A chalazion is a common non-effective granuloma of the meibomian glands of eyelids. They are commonly found on the tarsal conjunctival surface and the eyelid margins. It may be ignored by the patients until it reaches a considerable size. Recently the use of intralesional corticosteroids has shown promising results. We in the present study tried to evaluate the outcomes of intralesional triamcinolone acetonide injection in the management of Chalazion. Methods The current study was carried on Patients with chalazion attending Ophthalmology OPD of Rajiv Gandhi Institute of Medical Sciences, [RIMS], Adilabad. Successive patients with small multiple marginal chalazia were included. Patients were selected based on the amenability of treatment with intralesional triamcinolone acetonide injections. A chalazion is a common non-infective granuloma of the meibomian glands of eyelids. They are commonly found on the tarsal conjunctival surface and the eyelid margins. It may be ignored by the patients until it reaches a considerable size. Recently the use of intralesional corticosteroids has shown promising results. We in the present study tried to evaluate the outcomes of intralesional triamcinolone acetonide injection in the management of Chalazion. Results Group I with very small-sized chalazia< 5 mm out of n=22 included in Group I resolution after one week following treatment was found in 72.72%. Resolution following repeated injection after one week was found in 18.18%. In group II (chalazia size 5-7 mm) out of n=28 cases, 46.24% resolved after first injection and 39.28% cases resolved after the second injection and no resolution was found in 14.28% cases after one month. Conclusion Patients with small chalazia who are not amenable to incision and curettage intralesional triamcinolone acetonide injection appear to be a better option. Intralesional triamcinolone acetonide injections were found to be effective in resolving acute and sub-acute chalazia of soft to firm consistency irrespective of their duration.

Prolonged release of VEGF and Ang1 from intralesionally implanted hydrogel promotes perilesional vascularization and functional recovery after experimental ischemic stroke

Injectable hydrogels can generate and support pro-repair environments in injured tissue. Here we used a slow-releasing drug carrying in situ-forming hydrogel to promote post-stroke recovery in a rat model. Release kinetics were measured in vitro and in vivo with MRI, using gadolinium-labeled albumin (Galbumin), which demonstrated prolonged release over multiple weeks. Subsequently, this hydrogel was used for long-term delivery of vascular endothelial growth factor (VEGF) and angiopoietin-1 (Ang1) (Gel VEGF + Ang1, n = 14), in a photothrombotically induced cortical stroke lesion in rats. Control stroke animals were intralesionally injected with saline (Saline, n = 10), non-loaded gel (Gel, n = 10), or a single bolus of VEGF + Ang1 in saline (Saline VEGF + Ang1, n = 10). MRI was executed to guide hydrogel injection. Functional recovery was assessed with sensorimotor function tests, while tissue status and vascularization were monitored by serial in vivo MRI. Significant recovery from sensorimotor deficits from day 28 onwards was only measured in the Gel VEGF + Ang1 group. This was accompanied by significantly increased vascularization in the perilesional cortex. Histology confirmed (re)vascularization and neuronal sparing in perilesional areas. In conclusion, intralesional injection of in situ-forming hydrogel loaded with pro-angiogenic factors can support prolonged brain tissue regeneration and promote functional recovery in the chronic phase post-stroke.

Evaluating serum level of thymidylate synthase in post burn keloid patients before and after intralesional injection of 5-fluorouracil

Background Keloids are fibrous lesions formed at the site of trauma due to types I and III collagen irregular production. The presence of thymidylate synthase (TS) is a must for DNA synthesis and repairs causing cell death. 5-fluorouracil (5-FU) is a fluorinated pyrimidine analogue acting as an anti-metabolic agent that inhibits thymidylate synthase and interferes with ribo-nucleic acid (RNA) synthesis. Objectives we aimed to evaluate the level of thymidylate synthase in post burn keloid patients before and after intralesional injection of 5-fluorouracil. Methods The study included 20 keloid patients and 20 healthy subjects as a control. Serum TS was estimated using commercially available enzyme-linked immunosorbent assay (ELISA) kits before and after treatment with 5-fluorouracil. Results There was a statistically significant difference in TS levels before and after 5-FU treatment (p < 0.05). Also, results have shown that 5-FU injection has good satisfactory results in treatment of keloid causing reduction in scar volume and symptoms improvement (90% of the patients improved). On the other hand, there was no statistically significant difference in TS levels and the outcomes of the treatment. Conclusion Our findings suggest that intralesional 5-FU injection in keloid has very satisfactory results. However, thymidylate synthase enzyme has a minimal role in evaluating the treatment of keloid, so further studies are required to elaborate the relation between this enzyme and keloid scars.

Comparison Of Collagen-Curcumin Blend (Collaper Rtu)With Intralesional Steroid Injections in Oral Submucous Fibrosis a Randomized, Open-Label Interventional Study.

Introduction: Oral Submucous Fibrosis (OSMF) is a precancerous condition characterized by limited mouth opening, burning sensation, stiffness, and blanching of the oral mucosa induced by areca nut eating. With any of the current therapy regimens, complete regression of the illness has not been accomplished in all patients. Curcumin is a yellow pigment found in curry powder that has antioxidant, anti-inflammatory, and pro-apoptotic properties. As a result, interventional research was conducted to determine the efficacy of Collaper RTu a proprietary collagen-curcumin based product in patients with OSMF.Setting and design: Forty patients with clinically and histologically confirmed Oral Submucous Fibrosis participated in a randomized open label interventional research. Method & materials: For the research, forty patients with clinically and histologically verified Oral Submucous Fibrosis were randomly assigned to one of two groups. The first group was given a weekly intralesional injection of 4 mg Dexamethasone and 1500 I.U Hyaluronidase, whereas the second was given two Collagen-Curcumin pills (Collaper Rtu 60mg Collagen with 100 mg Curcumin) every day for three months. On a weekly basis, the improvement of burning sensation, interincisal distance, and tongue protrusion was assessed.Results: From early to late stages, the burning feeling improved in both groups. Collaper Rtu was found to eliminate the burning feeling. In groups 1 and 2, the mean increase in interincisal distance was 3.13 mm and 1.25 mm, respectively. The interincisal distance improved significantly in both groups by the end of the first month. When compared to group 2, group 1's tongue protrusion recovered faster at the conclusion of the first month. Conclusion: Collaper RTu is useful and effective in lowering the burning feeling in people with early OSMF.

Comparative evaluation of efficacy of muscle relaxant, vasodilator and combined intralesional steroid with hyalaronidase use in oral submucous fibrosis

Oral Sub Mucous Fibrosis (OSMF) is a disease , which predominately occurs in Indians and South East Asians. It is characterised by mucosal rigidity of varying intensity due to fibroelastic changes of the juxta-epithelial layer, resulting in a progressive inability to open mouth. The main concern in the condition is the management of trismus and burning sensation of oral mucosa. this study was conducted to compare various medical treatment protocol of OSMF, so as to arrive at definitive and effective protocol for the management of OSMF. 105 patients of OSMF attending the ENT OPD and satisfying the criteria for inclusion were enrolled for the study. The subjects were randomly divided into age sex matched into three study groups( Dexa with hyaluronidase , Oral vasodilator, Muscle relaxant) in which the relief in symptoms was noted. Lycopene was given in all patients. Group A, patients were given intralesional injection Dexamethasone with Hyaluronidase biweekly for five weeks and marked improvement was seen in cases of pain with spicy food 13 cases (76.47%), followed by decreased in mouth opening 9 cases (56.25%). In Group B, oral vasodilator Tablet Pentoxifylline 400 mg TDS was given and showed improvement in difficulty in protruding tongue in 9 cases (60%), pain with spicy food 8 cases (50%), decreased mouth opening 6 cases (37.5%), oral ulceration 3 cases (42.85%). In Group C with muscle relaxant Tablet Myosone 50 mg BD showed improvement pain with spicy food 8 cases (42.10%), decreased mouth opening 8 cases (42.10), difficulty in swallowing 3 cases (37.5%). As there is still paramount of controversy regarding the ethology of OSMF there is no definite treatment protocol. Patients which received intralesional dexamethasone and hyaluronidase along with oral lycopene showed better clinical and symptomatic improvement in comparison to others groups, which at present appears to the best option for OSMF.

To Compare the Recurrence Rate of Strictures after Internal Optical Urethrotomy with Intralesional Injection of Mitomycin C versus without Mitomycin C Injection in Patients Presenting with Anterior Urethral Stricture

Background: The urethral strictures occurred due to narrowing of urethra. These may occur after an injury or ureteral or excretory system diseases, due to the injury to urothelium or corpus spongiosum that lead to the development of scar tissues. Mitomycin C can be used as chemotherapeutic agent because of its quality of being anti-tumour actions. Aim: To compare the recurrence rate of strictures after internal optical urethrotomy with intralesional injection of Mitomycin C versus without Mitomycin C injection in patients presenting with anterior urethral stricture. Study Design: Randomized controlled trial. Place and Duration of Study: Department of Urology, Lahore General Hospital, Lahore from 5th September 2016 to 5th March 2017. Methodology: Sixty male patients age 18-70 years, diagnosed with anterior (penile and bulbar) urethral stricture up to 2.0cm were included. Patients were randomly divided into two groups; Group A patients were treated with internal optical urethrotomy alone and Group B patients treated with internal optical urethrotomy with intralesional injection of Mitomycin C. After the procedure, an 18F or 20F indwelling catheter left for 7 days. After 6 months, surgical site evaluated and if stricture again developed, then recurrence labeled. Results: The mean age was 39.32±11.38 years, mean duration of stricture was 6.85±3.32 months and the mean stricture size was 1.21±0.45 cm. The recurrence occurred in 18 (30%) patients. Significant difference was noted for recurrence in both groups (p-value<0.05). Conclusion: The recurrence rate with anterior urethral stricture is significantly lower in with Mitomycin C as compared to without Mitomycin C. Keywords: Recurrence, Urethral stricture, Mitomycin C
