Abstract
OBJECTIVE To compare the visual and anatomical outcomes of intravitreal ranibizumab (group 1), bevacizumab (group 2), and triamcinolone (group 3) for center-involving diabetic macular edema. METHODS We retrospectively enrolled 275 eyes of 208 consecutive patients. Visual acuity (VA) in Early Treatment Diabetic Retinopathy Study (ETDRS) letters and central macular thickness (CMT) values on optical coherence tomography were extracted. Reported side effects were noted. RESULTS At 6 months, the mean changes in VA in group 1, group 2, and group 3 were +4.9, +4.3, and +4.6 letters, respectively (p = 0.911). Improvement of CMT at 6 and 24 months was significantly better in group 3 compared to groups 1 and 2 (p = 0.012 and p = 0.001, respectively). At 24 months, the only independent variable affecting the change in VA was initial VA (p = 0.020). Cataract and glaucoma prevalences were higher in group 3 (p = 0.000 and p = 0.001, respectively). CONCLUSIONS Three treatment methods had similar effects with regard to improvement in VA; however, intravitreal triamcinolone provided additional anatomical improvement.

Abstract
PURPOSE To quantify adrenocorticotropin and cortisol secretion after epidural glucocorticoid injection. METHODS Eight men (ages 25-63 year) were studied at baseline, 1, 4, and 12 weeks after triamcinolone (80 mg) injection epidurally. Adrenocorticotropin (pg/mL) and cortisol (µg/dL) were measured every 10 min for 4 h, and after Corticotropin-releasing hormone (CRH) (1 µg/kg) injection. RESULTS Epidural triamcinolone markedly suppressed: (1) pre-CRH injection ACTH (from 18 ± 3.1 to 4.8 ± 0.4: P < 0.01) and cortisol (from 12.2 ± 1.6 to 1.6 ± 0.3: P < 0.0001) at week 1, with recovery at 4 weeks, and (2) CRH-stimulated 3-h summed ACTH (from 633 ± 116 to 129 ± 10 pg/mL, P < 0.0001), and 3-h summed cortisol at week 1 (from 385 ± 29 to 56 ± 22 µg/dL, P < 0.0001) and 4 weeks (284 ± 53; P < 0.01). Serum cortisol was <18 µg/dL in eight of eight men at 4 weeks, and six of eight men at week 12. Urinary-free cortisol (µg/24 h) remained low at week 12: baseline (60 ± 6.5); week 1 (9.0 ± 1.3, P < 0.01); week 4 (36 ± 8.6) and week 12 (38 ± 4.1). Urinary cortisol/cortisone ratios rose at week 4 only. Serum triamcinolone peaked at week 1 (16/16 samples), declining at week 4 (13/16 samples) and week 12 (6/16 samples). LIMITATIONS Relatively small group. CONCLUSION Epidural triamcinolone suppresses unstimulated and CRH-stimulated ACTH and cortisol secretion for 1-4 weeks but urinary free cortisol ≥12 weeks. Suppression of ACTH and cortisol after glucocorticoid treatment is thus complex.

Abstract
BACKGROUND Herpes zoster (HZ) is associated with inflammation of the peripheral nerves, which is considered to be an important cause of postherpetic neuralgia (PHN). Interventions aimed at reducing this inflammation could prevent PHN. One option is the epidural administration of corticosteroid and local anesthetic. However, several authors have reported a risk of arachnoiditis with epidural corticosteroids. Subcutaneous injection in an outpatient setting is a safer option. However, there is limited evidence of the effectiveness of this alternative for preventing PHN. OBJECTIVES The aim of this study was to assess the effectiveness of subcutaneous injection of triamcinolone and lidocaine for the prevention of PHN in elderly HZ patients. STUDY DESIGN Randomized, single-center, clinical trial. SETTING Department of pain management of a teaching hospital in Beijing, China. METHODS Patients with acute HZ with rash < 7 days (n = 100) were randomly assigned to receive either standard therapy (oral antivirals and analgesics) alone or standard therapy plus subcutaneous injection of triamcinolone and lidocaine. The severity of pain was assessed using a numeric rating scale (NRS) at enrollment and at one, 3, and 6 months after rash onset. Quality of life (QoL) was evaluated by the SF-36 before treatment and at 3 and 6 months after rash onset. The primary endpoint was the presence of zoster-associated pain (ZAP) at 3 months after rash onset. RESULTS At enrollment, all patients reported ZAP with average NRS scores of 6.64 ± 1.44 and 7.16 ± 1.22 in the standard group and subcutaneous group, respectively. At 3 and 6 months after rash onset, the pain had decreased in both groups, but the decrease was significantly greater in the subcutaneous injection group. At 3 months, 2 (4%) patients in the subcutaneous injection group vs. 10 (20%) patients in the standard group had ZAP with NRS > 3 (P = 0.014). Both groups showed significant improvement in QoL at 3 and 6 months. No patient had major adverse events related to the subcutaneous injection. LIMITATIONS The main limitation of the study was the absence of a placebo subcutaneous injection in the standard group. CONCLUSION Subcutaneous injection of triamcinolone and lidocaine in the acute phase of HZ can reduce ZAP more effectively than oral antivirals and analgesics alone, and may be a feasible method to prevent PHN. KEY WORDS Subcutaneous injection, lidocaine, triamcinolone, postherpetic neuralgia, prevention.

Abstract
Corticosteroids have been a mainstay of therapy for the treatment of many inflammatory diseases for well over 50 years. Cutaneous side effects of local corticosteroid therapy include striae, thinning of the skin, hypopigmentation, and atrophy, which are well known complications of this treatment modality.Herein, we present an unusual cutaneous adverse side effect rarely seen in intra-articular corticosteroid injections.

Abstract
Intra-articular hip injections have proven clinical value for both diagnostic and therapeutic purposes. Historically, these injections have been performed by radiologists using fluoroscopic guidance. This necessitates a radiology referral, delays the injection, and represents lost productivity for the orthopedist. Ultrasound-guided intra-articular hip injections have been described in the radiology literature with excellent accuracy. These injections were performed by radiologists. The purpose of this study was to determine the accuracy of ultrasound-guided hip injections performed in the orthopedic clinic by orthopedic surgeons and orthopedic physician assistants. Fifty ultrasound-guided hip injections were performed using a standard technique. Contrast was included, and an anteroposterior pelvis radiograph was obtained immediately following injection. Diagnosis, body mass index, procedure time, and visual analog scale scores were recorded. Radiographs were reviewed independently by a musculoskeletal radiologist and an orthopedic surgeon to determine intra-articular placement of the injection. A total of 50 hips were injected. There was no identifiable contrast in 2 patients, leaving 48 hips for analysis. Of these, contrast was injected intra-articularly in 46 hips for an accuracy of 96%. Average procedural time was 2.6 minutes, and the average visual analog scale score was 1.9 during the procedure. Revenue value units ranged from 1.72-2.55 for ultrasound-guided hip injections. These findings indicate ultrasound-guided intra-articular hip injections performed in the orthopedic clinic by surgeons or physician assistants are accurate, efficient, and patient-friendly. Additionally, they preserve patient continuity and maintain productivity within the orthopedic clinic. [Orthopedics. 2017; 40(2):96-100.].

Abstract
OBJECTIVE To evaluate the efficacy of intravitreal therapies in cases of atrophic age-related macular degeneration (AMD) with subretinal or intraretinal fluid. METHODS A retrospective review was made of the clinical charts of patients diagnosed with atrophic AMD with subretinal or intraretinal fluid. Fundus photographs and spectral-domain optical coherence tomography images were examined, and an analysis was made on the presence of fluid and its density. Neovascularisation was ruled out by fluorescein and/or indocyanine green angiography. RESULTS The study included 14 eyes from 13 patients with a mean age of 72.64 years and a mean follow-up of 80.5 weeks. Intraretinal fluid was observed in 6 eyes (42.9%), while subretinal fluid was shown in 8 eyes (57.1%), with high density in 4 eyes (28.5%), and low density in 4 eyes (28.5%). Snellen best-corrected visual acuity improved from 0.37 at baseline to 0.56 at the final visit (P=.002). Central subfield thickness (microns) significantly decreased (P<.001) from 291.0 at baseline to 228.9 at the final visit. Eight eyes received ranibizumab, 5eyes received bevacizumab, and one case received triamcinolone. CONCLUSIONS Cases of atrophic AMD may present with subretinal or intraretinal fluid in the absence Neovascularisation. Further studies are required to analyse the value of this finding as a risk factor of developing advanced forms of AMD, as well as the efficacy of intravitreal therapies.

Abstract
BACKGROUND The injection of antiangiogenic agents, such as ranibizumab (Lucentis®) and bevacizumab (Avastin®) into the anterior chamber of the eye represents a suitable alternative for treating neovascular glaucoma by reducing intraocular pressure. OBJECTIVES As the antiangiogenic substances are in direct contact with the sensitive corneal endothelium, the aim of this study was to show the effects of intracameral injection of ranibizumab and bevacizumab on this cell layer. METHODS Each injection consisted of 50 µl containing either ranibizumab (0.5 mg/0.05 ml), bevacizumab (1.25 mg/0.05 ml) or triamcinolone containing benzyl alcohol (2 mg/0.05 ml) which was used as the control group. These compounds were injected into the anterior chamber of pig eyes. Afterwards the corneas were dissected, fixed, examined by a scanning electron microscopy and evaluated according to a specified score. Assessment of the endothelium was carried out by evaluating the condition of microvilli, cell borders, cell surface and cell pattern. The findings were compared to untreated corneas and those injected with 50 µl of balanced salt solution (BSS). RESULTS The corneal endothelium exposed to the antiangiogenic substances showed only minor changes in comparison to the controls treated only with BSS. Also seen during this research was the irreversible cell damage in the control group using triamcinolone. CONCLUSION Ranibizumab and bevacizumab have no damaging effects on the corneal endothelium when used in the anterior chamber. They can be administered as an intracameral injection for the treatment of rubeotic secondary glaucoma. Triamcinolon containing benzyl alcohol causes severe damage to the endothelial cells of the cornea by direct contact.

Abstract
OBJECTIVE To compare the safety and efficacy of single injection of sub-tenon triamcinolone and topical dexamethasone in reducing post-operative inflammation after phacoemulsification and intraocular lens implantation. METHODS The randomised controlled study was conducted at Khyber Teaching Hospital, Peshawar, Pakistan, from September 2013 to February 2014. Patients who had undergone uneventful phacoemulsification with intraocular lens implantation by the same surgeon were included. Patients in Group A received 0.1% dexamethasone eye drops and those in Group B received sub-tenon triamcinolone injection (40mg/1ml). Follow-up was at 1st day, 14th day and 6 weeks post-operatively. At follow-up visit, grades of anterior chamber cells and aqueous flare were examined with slit lamp, and intraocular pressure was recorded. RESULTS Of the 108 patients, each group had 54(50%) subjects. The mean age was 58.87±9.69 years (range: 33 to 84 years) in Group A and 57.77±8.93 years (range: 30 to 78 years) in Group B (p=0.544). On the first post-operative day, all the patients in both groups had some degree of inflammation in the anterior chamber. On the 14th post-operative day, anterior chamber cells were present in 4(7.4%) eyes in Group A and in 3(5.55%) eyes in Group B (p>0.999), while aqueous flare was present in 5(9.25%) eyes in Group A and 9(16.66%) eyes in Group B (p=0.391). Six weeks after the operation, no anterior chamber cells or aqueous flare was seen in any eye in either group. CONCLUSIONS Sub-tenon triamcinolone injection was found to be a safe and effective alternative to topical dexamethasone for control of post-operative inflammation after phacoemulsification.

Abstract
BACKGROUND Esophageal endoscopic submucosal dissection enables en bloc resection of large superficial esophageal cancer; however, this procedure may induce severe stricture. Intralesional steroid injection is an effective treatment for prevention of stricture after endoscopic resection; however, there have been no studies assessing the duration of such treatment. The aim of this study was to reduce treatment duration and to evaluate the effectiveness of weekly and biweekly steroid injections in preventing esophageal stricture after endoscopic resection. PATIENTS METHOD We performed a randomized controlled trial comparing patients receiving weekly or biweekly intralesional triamcinolone injections. Patients with a mucosal defect greater than 75% (3/4) of the luminal circumference after esophageal endoscopic submucosal dissection for superficial esophageal cancers were enrolled. The primary endpoint was the duration of steroid injection treatment. RESULTS The median duration of treatment was 37.0 days in the weekly group and 34.2 days in the biweekly group (P = 0.059). Among patients with a mucosal defect larger than 50 mm, there was a significant difference in the median duration of treatment between the weekly and biweekly groups (42.5 days vs 29.0 days, P = 0.013). CONCLUSION Biweekly steroid injection of triamcinolone reduces treatment duration, particularly in those with mucosal defects larger than 50 mm. (Acta gastro-enterol. belg., 2016, 79, 315-320).

Abstract
INTRODUCTION Irritation, such as burning and stinging, on the site of application, is a common side effect of topical dermatologic products including creams, lotions, sprays, and foams. This effect may be more pronounced when applying products to atopic or psoriatic skin. The composition of the vehicle may affect the extent of the irritation. This study compared the irritation and erythema potential of 7 different topical dermatologic products to determine the products with the least likelihood of causing discomfort when applied.<br/> METHODS Seven sites on the anterior leg of 30 subjects were dry shaven with 10 upward strokes. Subjects rated the stinging of petrolatum (negative control), isopropyl alcohol (positive control), Cetaphil Lotion, triamcinolone 0.1% cream, triamcinolone 0.2% spray, betamethasone foam, and clobetasol 0.05% spray, 1 minute after product application, using a scale of 0 (no symptoms) to 10 (intolerable stinging/burning). The investigator assessed erythema at the sites 30 minutes after application of the products using a scale of 0 (none) to 4 (severe).<br/> RESULTS Stinging rating score of each product was statistically significant from one another. Petrolatum produced the least stinging (0) and isopropyl alcohol the most (10). Stinging with triamcinolone spray, Cetaphil Lotion, and triamcinolone cream ranked in the lower half of the rating scale (all below 5). Betamethasone foam and clobetal spray ranked the highest at >7. When corrected for the erythema caused by shaving, triamcinolone spray and Cetaphil Lotion produced the least amount of erythema of all the products tested.<br/> DISCUSSION Rapid evaporation of the volatile vehicle of triamcinolone spray and the non-irriating nature of the medication left behind may contribute to its low erythema and stinging. This product may be an appropriate choice for patients with compromised skin but who require the advantages and conveniences of a spray vehicle. <br /><br /> <em>J Drugs Dermatol.</em> 2016;15(7):870-873.

Abstract
Pain levels of 3 knee intra-articular corticosteroid injection sites were assessed to determine if an optimal site exists. Patients were stratified by site, demographic, and disease characteristics. All injections were performed by 1 surgeon using a uniform technique. Pain severity was assessed before, 1 minute after, and 5 minutes after injection using a visual analog scale. Mean visual analog scale scores for the lateral suprapatellar, medial infrapatellar, and lateral infrapatellar injection sites were 7, 4, and 2 points, respectively, but this was not statistically significant. These results suggest intra-articular injections should be administered from an inferomedial or inferolateral site to minimize pain intensity. [Orthopedics. 2016; 39(3):e578-e581.].

Abstract
Melasma is a common acquired skin disorder. While different treatments are currently being used, in many cases it is refractory to treatment. According to the effects of topical steroids in decreasing skin pigmentation, we studied the efficacy of this new method for treatment of melasma. A total of 42 women with facial melasma, admitted to the department of dermatology of Hamadan, were enrolled in the study. They were divided randomly into two groups (A and B), group A (case) received subepidermal triamcinolone injections with a dose of 4 mg per cc and 5 mm intervals until complete blanching of melasma lesions, and group B (control) received Kligman's formula (hydroquinone 5%, tretinoin 0.1%, and dexamethasone 0.1%). At the first visit, we completed the MASI score papers, and we repeated that at weeks 4 and 8 of the study. We followed them for two months, every two weeks. At each visit, side effects and clinical response to treatment were noted. A decrease in MASI was observed in both group (11.57 ± 4.33 vs 9.31 ± 3.75 at 4th week and vs 8.01 ± 3.1 at 8th week, P-value < 0.001 in group A, and 10.46 ± 5.61 vs 9.76 ± 5.21 at 4th week and vs 8.96 ± 4.96 at 8th week, P-value< 0.001 in group B). In comparison between 2 groups, response to treatment was much better in group A than group B (P-value<0.001). In comparison to topical treatments, based on these findings, triamcinolone microinjection is a new, safe and strong therapeutic method for treatment of melasma.

Abstract
Port-wine stains (PWSs), or capillary malformations, are common congenital lesions, but acquired lesions rarely present in the setting of trauma. We present the case of an 18-year-old man who developed a PWS and associated localized eczema following penetrating trauma to the left abdomen. The diagnoses were confirmed on biopsy. The patient's eczema improved with topical steroids. Magnetic resonance imaging of PWSs is recommended in order to rule out deeper arteriovenous malformations. More research is needed to elucidate the connection between PWS pathophysiology and the development of eczema.

Abstract
Steroids have been extensively used to treat macular edema due to diabetic retinopathy, venous occlusive disease, ocular inflammation and, to a lesser extent, also in some cases of choroidal neovascularization. The various intraocular steroids that have been employed include dexamethasone, triamcinolone and fluocinolone. During the past few years, new drug delivery methods for corticosteroids have been developed and are now part of our therapeutic armamentarium. This chapter provides a brief description of the pharmacology, efficacy and adverse effects associated with the use of steroids in various retinal diseases.

BACKGROUND Central retinal vein occlusion (CRVO) is a common retinal vascular abnormality associated with conditions such as hypertension, diabetes, glaucoma, and a wide variety of hematologic disorders. Macular edema (ME) represents an important vision-threatening complication of CRVO. Intravitreal steroids (IVS), such as triamcinolone acetonide, have been utilized to treat macular edema stemming from a variety of etiologies and may be a treatment option for CRVO-ME. OBJECTIVES To explore the effectiveness and safety of intravitreal steroids in the treatment of CRVO-ME. SEARCH METHODS We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (2014 Issue 10), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to November 2014), EMBASE (January 1980 to November 2014), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com), ClinicalTrials.gov (www.clinicaltrials.gov) and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 13 November 2014. For all included primary studies, we used The Science Citation Index (3 December 2014) and manually reviewed reference lists to identify other possible relevant trials. SELECTION CRITERIA We included randomized controlled trials (RCTs) that compared intravitreal steroids, of any dosage and duration of treatment of at least six months, with observation for the treatment of CRVO-ME. DATA COLLECTION AND ANALYSIS Two review authors independently screened titles and abstracts identified from the electronic searches and assessed full-text articles from potentially eligible trials. Two review authors independently assessed trial characteristics, risk of bias, and extracted data from included trials. We contacted investigators of included trials for desired data not provided in the trial reports. MAIN RESULTS We included two RCTs that enrolled a total of 708 participants with CRVO-ME. SCORE compared triamcinolone acetonide intravitreal injections (n = 165) with observation (n = 72); GENEVA compared dexamethasone intravitreal implants (n = 290) with sham injections (n = 147). We observed characteristics indicative of high risk of bias due to incomplete outcome data in SCORE and selective outcome reporting in GENEVA. Loss to follow-up was high with 10% in the steroid groups and almost twice as much (17%) in the observation group. GENEVA enrolled participants with both branch and central retinal vein occlusion, but did not present subgroup data for the CRVO-ME population. A qualitative assessment of the results from GENEVA indicated that the dexamethasone implant was not associated with improvement in visual acuity after six months among participants with CRVO-ME. Although the SCORE investigators reported that participants treated with 1 mg (n = 82) or 4 mg (n = 83) triamcinolone intravitreal injections were five times more likely to have gained 15 letters or more in visual acuity compared with participants in the observation group (1 mg; risk ratio (RR): 5.27; 95% confidence interval (CI) 1.62 to 17.15; 4 mg RR 4.92; 95% CI 1.50 to 16.10) by the eighth-month follow-up examination, the average visual acuity decreased in all three groups. However, eyes treated with triamcinolone lost fewer letters than participants in the observation group at 8 months (1 mg mean difference (MD): 8.70 letters, 95% CI 1.86 to 15.54; 4 mg MD: 9.80 letters, 95% CI 3.32 to 16.28). A higher incidence of adverse events was noted with IVS therapy when compared with observation alone. As many as 20% to 35% of participants experienced an adverse event in the IVS groups compared with 8% of participants in the observation group of the SCORE study. The GENEVA investigators reported 63% in the treatment arm versus 43% in the observation arm experienced an adverse event. The most commonly encountered adverse events were elevated intraocular pressure, progression of cataracts, and retinal neovascularization. We graded the quality of evidence as low due to study limitations, imprecision of treatment estimates, and selective outcome reporting. AUTHORS' CONCLUSIONS The two RCTs reviewed herein provide insufficient evidence to determine the benefits of IVS for individuals with CRVO-ME. The improvement in visual acuity noted in the SCORE trial should be interpreted with caution as outcome data were missing for a large proportion of the observation group. Adverse events were observed more often with IVS treatment compared with observation/no treatment.

Abstract
BACKGROUND Since the publication of guidelines by the UK National Institute for Health and Care Excellence (NICE) and the American Pain Society guidelines for low back pain in 2009 there have been deep divisions in the pain treatment community about the use of therapeutic intraarticular facet joint injections. While evidence for the effectiveness or not of intraarticular facet joint injections remains sparse, uncertainty will remain. The Warwick feasibility study, along with a concurrent study with a different design led by another group, aims to provide a stable platform from which the effectiveness and cost effectiveness of intraarticular facet joint injections added to normal care could be evaluated in randomized controlled trials (RCTs). OBJECTIVES To reach consensus on key design considerations for the Warwick facet feasibility study from which the study protocol and working manuals will be developed. STUDY DESIGN A consensus conference involving expert professionals and lay members. METHODS Preliminary work identified 5 key design considerations for deliberation at our consensus conference. Three concerned patient assessment and treatment: diagnosis of possible facet joint pain, interaarticular facet joint injection technique, and best usual care. Two concerned trial analysis: a priori sub-groups and minimally important difference and are reported elsewhere. We did systematic evidence reviews of the design considerations and summarized the evidence. Our design questions and evidence summaries were distributed to all delegates. This formed the basis for discussions on the day. Clinical experts in all aspects of facet joint injection from across the UK along with lay people were invited via relevant organizations. Nominal group technique was used in 15 facilitated initial small group discussions. Further discussion and ranking was undertaken in plenary. All small group and plenary results were recorded and checked and verified post conference. Where necessary participants were contacted via email to resolve outstanding issues. RESULTS Fifty-two delegates attended the conference with lay people and all relevant professions represented. Consensus was reached on the details of how to assess patients for facet joint pain, undertake the injections, and deliver usual care. Where post conference checking of results revealed errors in calculating ranking results on the day, consensus was reached by email consultation. All but 3 delegates agreed to be associated with the outcome. LIMITATIONS Allocating one day for discussing a wide range of topics imposed time pressure on discussion and calculation of the numerous rankings. CONCLUSIONS Through the use of an evidence-based, systematic, inclusive, and transparent process we have established consensus from expert health professionals in the UK, with lay input, on the clinical assessment of suspected facet joint pain, interaarticular injection for facet joint pain, and best usual care for use in a feasibility study for a proposed pragmatic clinical trial of interaarticular facet joint injections. This provides a strong basis for a clinical trial that will be acceptable to the pain treatment community.

Abstract
IMPORTANCE Primary cutaneous marginal zone lymphoma (PCMZL) is a low-grade malignant B-cell lymphoma that appears in the skin without any extracutaneous manifestations. Therapeutic mainstays for PCMZL have primarily included radiotherapy and surgery. Intralesional steroids have been found to resolve the lesions caused by PCMZL, but there is a dearth of literature regarding this therapy indicating that this is not a commonly favored treatment option. OBSERVATIONS We present a case of 60-year-old woman who presented with PCMZL on her right eyebrow. Three years later, after two courses of radiation and one relapse, the patient presented with new lesions on both arms, consistent once again with PCMZL. At this time, therapy with nine rounds of intralesional triamcinolone was attempted. After each round of triamcinolone, gradual improvement of the lesions was noted until complete resolution occurred. CONCLUSIONS AND RELEVANCE This case reminds practitioners that intralesional corticosteroids can be effectively and safely used to treat localized PCMZL. Intralesional steroids are less invasive, cheaper, and easier to administer than the majority of other recommended therapies for PCMZL. Thus, although they are often overlooked, intralesional corticosteroids should be more often considered when developing a treatment plan for localized PCMZL.

Abstract
OBJECTIVE To compare single intra-operative versus an intra-operative and two post-operative injections of triamcinolone after wedge excision of keloids of helix. METHODS The randomised controlled trial was conducted at the King Edward Medical University, Lahore, from January, 2011, to March, 2014, and comprised female patients over 14 years of age presenting with post-piercing keloids of helix not treated previously by any means and amenable to wedge excision. The subjects were divided into Group A who were given a single intra-operative injection of triamcinolone, and Group B who had an intra-operative and two post-operative injections of triamcinolone. Extra-lesional wedge excision of keloids was done, followed by infiltration of flaps and wound base with 0.5-1cc of triamcinolone 40mg/cc. Group B patients were given additional injections of triamcinolone at 1st and 2nd monthly visits. Both groups were observed for the evidence of hypertrophy or complications. Development of hypertrophy within one year of completion of treatment was considered recurrence. RESULTS The 70 patients in the study were divided into two equal groups of 35(50%) each. The mean age of Group A was 22.34±4.95 years and that of Group B was 22.88±4.22 years (p=0.624). The Mean size of the keloids was 2.54±0.516 cm(2) in Group A and 2.61±0.569 cm(2) in Group B (p=0.613). Recurrence rate in Group A was 3(8.5%) and 2(5.7%) in Group B (p= 0.64). The complication rate was 3(8.5%) in Group A and 8(22.8%) in Group B (p=0.10). CONCLUSIONS Single injection of triamcinolone was as effective as three in reducing recurrence with less complication rate.

Abstract
BACKGROUND AND AIMS Refractory benign strictures of the oesophagus can present a significant clinical challenge and may require repeated attempts at dilatation. Intralesional triamcinolone injections have been used in a limited number of studies to aid in the dilatation of benign, refractory oesophageal strictures. It is hypothesised that intralesional steroid injection inhibits the scar formation, thereby reducing the need for dilatations. The purpose of this study was to assess if steroid injection reduces the need for serial endoscopic dilatations and aids in maintaining oesophageal patency. METHOD We report a case series of 25 patients with refractory oesophageal strictures. The mean age was 75 years and range between 41-95 years. The etiology of strictures consisted of peptic (68%), anastomotic (4%), radiation induced (16%) and eosinophilic oesophagitis (12%). Majority (75%) were distal in location. Triamcinolone (40-80 mg) was injected via 25-gauge sclerotherapy catheter in a four quadrantic manner in aliquots of 0.5 ml each into the proximal end of the stricture and also into the stricture itself after dilatation. Dilatation was carried out with over the guidewire Savary-Gilliard or through the scope (CRE) Balloon dilators depending upon the preference of the endoscopist. Dilatations were continued every 4-6 weeks until asymptomatic and/or endoscopic resolution of stricture. Periodic Dilatation Index (PDI) was calculated by the number of dilatations required over the duration of time in months. RESULTS The number of dilatations reduced from mean of 3.12 to 1.41 in the peptic strictures but there was no decrease in the other groups. However, the triamcinolone injection resulted in reducing the periodic dilatation index in all groups except the eosinophilic oesophagitis. The rate ratio of PDI before and after intralesional triamcinolone injection use being 0.45 with 95% confidence interval [0.30 -0.68] (p=0.0005). Furthermore triamcinolone injections showed a trend to increase the maximal achieved diameter of the strictures. CONCLUSION This study demonstrates the efficacy of triamcinolone intralesional steroids in reducing the requirement for repeated dilatations in refractory peptic strictures of oesophagus. Strictures related to eosinophilic oesophagitis failed to demonstrate similar efficacy.

Abstract
BACKGROUND Branch retinal vein occlusion (BRVO) is the second most common cause of retinal vascular abnormality after diabetic retinopathy. Persistent macular oedema develops in 60% of eyes with a BRVO. Untreated, only 14% of eyes with chronic macular oedema will have a visual acuity (VA) of 20/40 or better. Macular grid laser photocoagulation is used for chronic non-ischaemic macular oedema following BRVO and has been the mainstay of treatment for over 20 years. New treatments are available and a systematic review is necessary to ensure that the most up-to-date evidence is considered objectively. OBJECTIVES To examine the effects of macular grid laser photocoagulation in the treatment of macular oedema following BRVO. SEARCH METHODS We searched CENTRAL, Ovid MEDLINE, EMBASE, Web of Science Conference Proceedings Citation Index, the metaRegister of Controlled Trials (mRCT), ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform. We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 21 August 2014. SELECTION CRITERIA We included randomised controlled trials (RCTs) comparing macular grid laser photocoagulation treatment to another treatment, sham treatment or no treatment. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. MAIN RESULTS We included five studies conducted in Europe and North America. Four separate trials compared grid laser to no treatment, sham treatment, intravitreal bevacizumab and intravitreal triamcinolone. One further trial compared subthreshold to threshold laser. Two of these trials were judged to be at high risk of bias in one or more domains.In one trial of grid laser versus observation, people receiving grid laser were more likely to gain visual acuity (VA) (10 or more ETDRS letters) at 36 months (RR 1.75, 95% confidence interval (CI) 1.08 to 2.84, 78 participants, moderate-quality evidence). The effect of grid laser on loss of VA (10 or more letters) was uncertain as the results were imprecise (RR 0.68, 95% CI 0.23 to 2.04, 78 participants, moderate-quality evidence). On average, people receiving grid laser had better improvement in VA (mean difference (MD) 0.11 logMAR, 95% CI 0.05 to 0.17, high-quality evidence). In a trial of early and delayed grid laser treatment versus sham laser (n = 108, data available for 99 participants), no participant gained or lost VA (15 or more ETDRS letters). At 12 months, there was no evidence for a difference in change in VA (from baseline) between early grid laser and sham laser (MD -0.03 logMAR, 95% confidence interval (CI) -0.07 to 0.01, 68 participants, low-quality evidence) or between delayed grid laser and sham laser (MD 0.00, 95% CI -0.04 to 0.04, 66 participants, low-quality evidence).The relative effects of subthreshold and threshold laser were uncertain. In one trial, the RR for gain of VA (15 or more letters) at 12 months was 1.68 (95% CI 0.57 to 4.95, 36 participants, moderate-quality evidence); the RR for loss of VA (15 or more letters) was 0.56 (95% CI 0.06 to 5.63, moderate-quality evidence); and at 24 months the change in VA from baseline was MD 0.07 (95% CI -0.10 to 0.24, moderate-quality evidence).The relative effects of macular grid laser and intravitreal bevacizumab were uncertain. In one trial, the RR for gain of 15 or more letters at 12 months was 0.67 (95% CI 0.39 to 1.14, 30 participants, low-quality evidence). Loss of 15 or more letters was not reported. Change in VA at 12 months was MD 0.11 logMAR (95% CI -0.36 to 0.14, low-quality evidence).The relative effects of grid laser and 1mg triamcinolone were uncertain at 12 months. RR for gain of VA (15 or more letters) was 1.13 (95% CI 0.75 to 1.71, 1 RCT, 242 participants, moderate-quality evidence); RR for loss of VA (15 or more letters) was 1.20 (95% CI 0.63 to 2.27, moderate-quality evidence); MD for change in VA was -0.03 letters (95% CI -0.12 to 0.06, moderate-quality evidence). Similar results were seen for the comparison with 4mg triamcinolone. Beyond 12 months, the visual outcomes were in favour of grid laser at 24 months and 36 months with people in the macular grid group gaining more VA.Four studies reported on adverse effects. Laser photocoagulation appeared to be well tolerated in the studies. One participant (out of 71) suffered a perforation of Bruch's membrane, but this did not affect visual acuity. AUTHORS' CONCLUSIONS Moderate-quality evidence from one RCT supports the use of grid laser photocoagulation to treat macular oedema following BRVO. There was insufficient evidence to support the use of early grid laser or subthreshold laser. There was insufficient evidence to show a benefit of intravitreal triamcinolone or anti-vascular endothelial growth factor (VEGF) over macular grid laser photocoagulation in BRVO. With recent interest in the use of intravitreal anti-VEGF or steroid therapy, assessment of treatment efficacy (change in visual acuity and foveal or central macular thickness using optical coherence tomography (OCT)) and the number of treatments needed for maintenance and long-term safety will be important for future studies.

Abstract
Q-switched lasers, such as the neodymium:yttrium-aluminum-garnet (Nd:YAG) laser, are the gold standard for tattoo removal. Allergy to tattoo pigment is well-documented, but adverse allergic reactions during or shortly after laser tattoo removal are rare with few reports in the medical literature. Here we describe an intraoperative, localized urticarial reaction that developed during treatment of a tattoo using a 1064-nm Nd:YAG laser. As laser tattoo removal becomes increasingly popular amongst our patients, it is important for dermatologists to be aware of urticarial allergic reactions as well as their management. We outline our recommendations for medical management of this condition and hope that these guidelines will facilitate patient care by dermatologists who encounter this immune skin reaction to laser tattoo removal

Abstract
OBJECTIVE The aims of this study were to identify the characteristic ultrasound (US) findings of the first metatarsophalangeal joint (MTPJ1) in acute gout attack and to evaluate the efficacy and safety of US-guided intraarticular corticosteroid injection of the MTPJ1. METHODS We enrolled 21 patients with acute gout attack involving the MTPJ1 unilaterally. US evaluation of each affected MTPJ1 was compared with radiographic features. US-guided intraarticular corticosteroid (0.5 ml [20 mg] of triamcinolone mixed with 0.5 ml of 2% lidocaine) was injected into the affected MTPJ1s. Pain, general disability, and walking disability were assessed at baseline, 24 hours, 48 hours, and 7 days after injection with visual analog scales. RESULTS The characteristic US findings of MTPJ1 were erosion, joint effusion, synovial hypertrophy, tophus-like lesion, double contour, hyperechoic spots, and increased power Doppler signal in acute gout attack. US was more sensitive than conventional radiograph in detecting erosion and tophus-like lesion. The reductions of mean visual analog scale scores in pain, general disability, and walking disability were 48 mm (SD, 27), 35 mm (SD, 26) and 39 mm (SD, 26), respectively, 48 hours after US-guided intraarticular corticosteroid injection. There were no adverse events. CONCLUSIONS US is a sensitive tool to evaluate joint abnormality of the MTPJ1 in acute gout attack and US-guided intraarticular corticosteroid injection to this joint is effective and safe.

Abstract
Triamcinolone is a long-acting glucocorticoid medication that can be responsible for transient suppression of the hypothalamic–pituitary–adrenal (HPA) axis. This physiologic alteration may persist for weeks after repeated or even single localized injection of this agent. However, when this glucocorticoid agent is given to patients receiving the HIV protease inhibitor (PI) ritonavir (RTV),inhibition of their shared cytochrome P450 3A4 degradation pathway leads to an increased bioavailability of triamcinolone, with subsequent heightening and prolongation of the glucocorticoid serum levels. In those instances, iatrogenic Cushing syndrome may ensue. The authors encountered such an event in an HIV-infected patient on chronic treatment with an antiretroviral regimen containing RTV. The patient's clinical presentation and laboratory investigations confirmed a diagnosis of Cushing syndrome and secondary adrenal insufficiency. This was believed to have occurred in close association following cervical vertebral column facet joint injections with triamcinolone acetonide for cephalagia deemed related to cervical spine disease. The discontinuation of the RTV-boosted PI therapy alone, promoting the clearance of the elevated triamcinolone serum levels and restoration of HPAhomeostasis, proved successful in this patient. For this case, the authors review the published English medical literature relating to this uncommon phenomenon.
