Purpose To provide recommendations for diagnosis of vitreoretinal lymphoma (VRL). Methods Literature was reviewed for reports supporting the diagnosis of VRL. A questionnaire (Delphi 1 round) was distributed to 28 participants. In the second round (Delphi 2), items of the questionnaire not reaching consensus (75% agreement) were discussed to finalize the recommendations. Results Presenting symptoms include floaters and painless loss of vision, vitreous cells organized into sheets or clumps. Retinal lesions are usually multifocal creamy/white in the outer retina. Other findings include retinal lesions with "leopard-skin" appearance and retinal pigment epithelium atrophy. Severe vitreous infiltration without macular edema is the most likely presentation. Diagnostic vitrectomy should be performed. Systemic corticosteroid should be discontinued at least 2 weeks before surgery. An interleukin (IL)-10:IL-6 ratio > 1, positive mutation for the myeloid differentiation primary response 88 gene and monoclonality are indicators of VRL. Multi-modal imaging (optical coherence tomography, fundus autofluorescence) are recommended. Conclusions A consensus meeting allowed the establishment of recommendations important for the diagnosis of VRL.

Viral agents are the most common cause of infectious anterior uveitis worldwide. The purpose of this review is to analyze the frequency, gender and racial differences of viral anterior uveitis (VAU) in various populations.Systematized literature review of epidemiological reports of VAU cited in PubMed, EMBASE and the Cochrane Library database published until June 30th, 2020.A total of 12 clinical studies on epidemiology of definite VAU and 36 clinical studies of presumed VAU were identified. Members of Herpesviridae family represent the most common causes of VAU. Other less frequently reported causes, such as rubella and endemic viruses (HTLV-1, Chikungunya, Dengue, Ebola, Zika virus) were also analyzed.HSV, VZV are prevalent worldwide. CMV is more frequent in Asia, and rubella in the West. However, due to globalization and air travel, HTLV-1, Chikungunya, Dengue and Ebola may become important causes of VAU across the world.

Topic An international, expert-led consensus initiative organized by the Collaborative Ocular Tuberculosis Study (COTS), along with the International Ocular Inflammation Society and the International Uveitis Study Group, systematically developed evidence- and experience-based recommendations for the treatment of tubercular choroiditis. Clinical relevance The diagnosis and management of tubercular uveitis (TBU) pose a significant challenge. Current guidelines and literature are insufficient to guide physicians regarding the initiation of antitubercular therapy (ATT) in patients with TBU. Methods An international expert steering subcommittee of the COTS group identified clinical questions and conducted a systematic review of the published literature on the use of ATT for tubercular choroiditis. Using an interactive online questionnaire, guided by background knowledge from published literature, 81 global experts (including ophthalmologists, pulmonologists, and infectious disease physicians) generated preliminary consensus statements for initiating ATT in tubercular choroiditis, using Oxford levels of medical evidence. In total, 162 statements were identified regarding when to initiate ATT in patients with tubercular serpiginous-like choroiditis, tuberculoma, and tubercular focal or multifocal choroiditis. The COTS group members met in November 2018 to refine these statements by a 2-step modified Delphi process. Results Seventy consensus statements addressed the initiation of ATT in the 3 subtypes of tubercular choroiditis, and in addition, 10 consensus statements were developed regarding the use of adjunctive therapy in tubercular choroiditis. Experts agreed on initiating ATT in tubercular choroiditis in the presence of positive results for any 1 of the positive immunologic tests along with radiologic features suggestive of tuberculosis. For tubercular serpiginous-like choroiditis and tuberculoma, positive results from even 1 positive immunologic test were considered sufficient to recommend ATT, even if there were no radiologic features suggestive of tuberculosis. Discussion Consensus guidelines were developed to guide the initiation of ATT in patients with tubercular choroiditis, based on the published literature, expert opinion, and practical experience, to bridge the gap between clinical need and available medical evidence.

Topic The Collaborative Ocular Tuberculosis Study (COTS), supported by the International Ocular Inflammation Society, International Uveitis Study Group, and Foster Ocular Immunological Society, set up an international, expert-led consensus project to develop evidence- and experience-based guidelines for the management of tubercular uveitis (TBU). Clinical Relevance The absence of international agreement on the use of antitubercular therapy (ATT) in patients with TBU contributes to a significant heterogeneity in the approach to the management of this condition. Methods Consensus statements for the initiation of ATT in TBU were generated using a 2-step modified Delphi technique. In Delphi step 1, a smart web-based survey based on background evidence from published literature was prepared to collect the opinion of 81 international experts on the use of ATT in different clinical scenarios. The survey included 324 questions related to tubercular anterior uveitis (TAU), tubercular intermediate uveitis (TIU), tubercular panuveitis (TPU), and tubercular retinal vasculitis (TRV) administered by the experts, after which the COTS group met in November 2019 for a systematic and critical discussion of the statements in accordance with the second round of the modified Delphi process. Results Forty-four consensus statements on the initiation of ATT in TAU, TIU, TPU, and TRV were obtained, based on ocular phenotypes suggestive of TBU and corroborative evidence of tuberculosis, provided by several combinations of immunologic and radiologic test results. Experts agreed on initiating ATT in recurrent TAU, TIU, TPU, and active TRV depending on the TB endemicity. In the presence of positive results for any 1 of the immunologic tests along with radiologic features suggestive of past evidence of tuberculosis infection. In patients with a first episode of TAU, consensus to initiate ATT was reached only if both immunologic and radiologic test results were positive. Discussion The COTS consensus guidelines were generated based on the evidence from published literature, specialists’ opinions, and logic construction to address the initiation of ATT in TBU. The guidelines also should inform public policy by adding specific types of TBU to the list of conditions that should be treated as tuberculosis.

To present a case of necrotizing sclerokeratitis in a patient with multidrug-resistant tuberculosis and study the challenges in diagnosis and management of anterior tuberculous scleritis.Retrospective observational case report and review of anterior tuberculous scleritis.A 28-year-old woman, previously diagnosed as presumed tubercular panuveitis, presented with necrotizing sclerokeratitis and progressed to develop panophthalmitis. Laboratory investigations revealed multidrug-resistantDiagnosis of tuberculous scleritis is a challenge. Therapeutic failure must alert the clinician for drug resistance which is diagnosed early, can prevent the devastating outcomes.

A 75-year-old woman with a history of Type 2 Diabetes mellitus attended triage with complaints of nausea, occasional vomit, pain in epigastrium and some vague heaviness in breathing of 4-5 days duration. On her physical examination she had mild tachypnea, peripheral capillary oxygen saturation (SpO2) 92% on room air, and high blood glucose and ketones respectively. She was evaluated and diagnosed to have bilateral submassive pulmonary Thromboemboli. She was managed with fibrinolytic treatment, Heparin, and supportive treatment along with management of Diabetic Ketoacidosis (DKA). Etiological examinations did not reveal any underlying cause. The contribution of diabetes and its acute complication, DKA, to the development of pulmonary thromboembolism is controversial and is discussed. This case with the presentation of sub-massive pulmonary embolism in a patient of DKA with no underlying cause identified is being reported owing to its rareness.

Uveitis is a complex disorder including both infectious and non-infectious etiologies. Clinical diagnosis is a challenge because many diseases share common clinical signs. Laboratory support is crucial for confirming the clinical diagnosis. Laboratory diagnosis includes direct tests and indirect tests. For example smear, culture, and molecular diagnostics demonstrate the pathogens, hence they are direct tests. Immunologic tests employ an antigen to detect presence of antibodies to a pathogen, or an antibody to detect the presence of an antigen, of the pathogen in the specimens. The immunological tests used in laboratories are made by producing artificial antibodies that exactly "match" the pathogen in question. When these antibodies come into contact with a sample they bind to the matching pathogen if found in the sample. Hence they are grouped under indirect evidence. There are several investigations in uveitis to reach the confirmed diagnosis including microbiological, immunological, imaging and molecular diagnostic testing. In this section we will discuss immunological investigations of infectious and non-infectious uveitis.

To describe the role of optical coherence tomography (OCT) in detecting subclinical choroidal inflammation and early diagnosis of macular complications in chronic Vogt-Koyanagi-Harada (VKH) disease with sunset glow fundus.Retrospective observational study. Clinical features, OCT images, treatment, and visual outcome were analyzed.Fourteen patients (9 females and 5 males) were included in the study. Mean age was 39 years (range 7-67 years). Mean duration of disease was 5.25 years (range 1-15 years). Anterior uveitis was seen in 14 eyes (52%). Fundus examination showed sunset glow fundus in all patients with no obvious macular pathology. OCT showed macular edema in 16 eyes (59%), choroidal neovascular membrane in 8 eyes (30%), and macular hole in 3 eyes (11%).OCT should be regularly used to detect subclinical inflammation and early macular complications in chronic VKH disease where sunset glow fundus may delay the clinical diagnosis thus causing permanent damage.

To report a case of ocular Gnathostomiasis presenting as branch retinal artery occlusion.Observational case report.A 22-year-old Asian woman presented to her ophthalmologist with redness, tearing, and decreased vision in her left eye. Examination revealed anterior uveitis and branch retinal artery occlusion associated with both intra-retinal and vitreous hemorrhage. The patient was treated with topical corticosteroids and cycloplegics. After 3 weeks, she presented in our emergency, with further decrease in vision and worsening pain in the left eye. Slit lamp examination revealed a brown colored live worm on the posterior corneal surface, anterior uveitis, multiple iris holes, and vitreous cells. Indirect ophthalmoscopy showed focal retinal hemorrhages, subretinal tracts, and vitreous hemorrhage. Surgical removal of the worm from anterior chamber was done immediately.Branched retinal artery occlusion with intraretinal and vitreous hemorrhage, panuveitis, and multiple iris holes may suggest the presence of an intraocular parasite.

Purpose To report a unique case of bilateral Chandler syndrome with recurrent band keratopathy. Methods This is a retrospective observational case report. Results A 39-year-old Asian man presented with progressive painless diminution of vision in both eyes for 6 years. Examination revealed diffuse corneal edema, hammered silver appearance of endothelium with guttae-like lesions, and corectopia in the right eye and mild corneal edema, central band keratopathy, and guttae-like lesions on the endothelium and peripheral anterior synechiae in the left eye. Routine specular microscopy, confocal microscopy, and pachymetry were performed. A clinical diagnosis of bilateral Chandler syndrome with band keratopathy was made. Superficial epithelial keratectomy with ethylenediaminetetraacetic acid (EDTA) chelation was performed in the left eye first, followed by Descemet-stripping automated endothelial keratoplasty in the right eye. Histopathological examination of the surgically excised Descemet membrane in the right eye showed multilayered endothelium with adhered epithelial cells consistent with Chandler syndrome. At 9-month follow-up, the right eye showed a clear cornea with an attached graft and the left eye revealed recurrence of central band keratopathy for which repeat EDTA chelation was successfully performed. Conclusions Recurrent band keratopathy coincident with endothelial dysfunction in iridocorneal endothelial syndrome can be repeatedly treated with EDTA chelation, whereas endothelial keratoplasty might be delayed until the time point of corneal decompensation.

Introduction: Uveitic macular edema (UME) is a significant cause of visual impairment in all uveitis types. Methods: Reports that were cited in the MEDLINE database, that analyzed the effectiveness of biologics for UME in at least five patients, with a minimum follow-up of 3 months, published prior to April 1, 2019 were included. Reports that did not compare UME findings before and after the therapy, using either OCT or fluorescein angiography, were excluded. Results: Case series that analyzed the efficacy of intravitreal anti-VEGF agents showed modest, short-term benefit. Studies that investigated systemic anti-TNF agents in patients with noninfectious uveitis reported a therapeutic effect on UME. Anti-IL-6 antibodies have shown promising results for most severe cases of noninfectious UME. Interferon represents an option for patients with persistent UME in infectious and noninfectious uveitis. Conclusion: Multicenter, randomized controlled trials are needed to assess the effectiveness of each group of biologic agents in sufficient number of patients.

An international, expert led consensus initiative was set up by the Collaborative Ocular Tuberculosis Study (COTS) group to develop systematic, evidence, and experience-based recommendations for the treatment of ocular TB using a modified Delphi technique process. In the first round of Delphi, the group identified clinical scenarios pertinent to ocular TB based on five clinical phenotypes (anterior uveitis, intermediate uveitis, choroiditis, retinal vasculitis, and panuveitis). Using an interactive online questionnaires, guided by background knowledge from published literature, 486 consensus statements for initiating ATT were generated and deliberated amongst 81 global uveitis experts. The median score of five was considered reaching consensus for initiating ATT. The median score of four was tabled for deliberation through Delphi round 2 in a face-to-face meeting. This report describes the methodology adopted and followed through the consensus process, which help elucidate the guidelines for initiating ATT in patients with choroidal TB.

Purpose: Tubercular intermediate uveitis (TIU) and panuveitis (TBP) are difficult to manage because of limitations in diagnostic tools and lack of evidence-based treatment guidelines. The Collabora...

PurposeTo report clinical profile and compare management options for Pythium keratitis.MethodRetrospective interventional study of 46 patients diagnosed as Pythium keratitis by PCR DNA sequencing from January 2014 to July 2017. Interventions were categorised into medical management (MM) (topical azithromycin and linezolid with oral azithromycin at presentation), surgery (S) (therapeutic penetrating keratoplasty, TPK), surgical adjunct (SA) (cryotherapy±alcohol with TPK) and medical adjunct (MA) (MM after TPK).ResultsPrimary treatment included MM (1 eye), SA (3 eyes) and S (42 eyes). Recurrence occurred in 27/43 eyes (MM+S group). Second surgery (S) was required in 11 eyes (TPK-2), with additional procedures (SA) in 10 eyes and evisceration in five eyes. 8/43 eyes received MA after TPK-1. One eye required TPK-3. Recurrence occured in all eyes that received MA (100%) and in 28 of 54 TPKs (51.8%) (TPK 1+2+3) in 42 eyes. Recurrence was noted in 1/14 (7.1%) that underwent SA.ConclusionThe currently available and recommended treatment for Pythium keratitis is surgical by means of a TPK and in worse cases evisceration. In our study, MM/MA measures showed no benefit with recurrence or worsening of infection requiring resurgery. Almost 50% of TPKs had a recurrence requiring resurgery. However, adjunctive procedures during TPK appear to have additional benefit with low risk of recurrence and could be included as routine care.

Purpose: To standardize a nomenclature system for defining clinical phenotypes, and outcome measures for reporting clinical and research data in patients with ocular tuberculosis (OTB).Methods: Uveitis experts initially administered and further deliberated the survey in an open meeting to determine and propose the preferred nomenclature for terms related to the OTB, terms describing the clinical phenotypes and treatment and reporting outcomes.Results: The group of experts reached a consensus on terming uveitis attributable to tuberculosis (TB) as tubercular uveitis. The working group introduced a SUN-compatible nomenclature that also defines disease "remission" and "cure", both of which are relevant for reporting treatment outcomes.Conclusion: A consensus nomenclature system has been adopted by a large group of international uveitis experts for OTB. The working group recommends the use of standardized nomenclature to prevent ambiguity in communication and to achieve the goal of spreading awareness of this blinding uveitis entity.

Background: Tuberculosis (TB) is a major infection that can affect the eye as first and sole presentation without features of systemic disease. Controversy exists regarding diagnosis and management of tubercular uveitis (TBU), further compounded by regional variations in disease expression. Purpose: Collaborative Ocular Tuberculosis Study (COTS)-1 aims to address knowledge deficits through collaboration amongst uveitis specialists across the globe by sharing the data of patients with TBU presented at participating centers from January 2004 to December 2014. Methods: Data collection was facilitated by a novel method of real-time encrypted web-based data entry allowing regular updates as new data and recommendations become available. Results: Information on clinical features, investigation findings, management, and treatment outcomes were reviewed to get an idea about real world scenario. Conclusion: The current review aims to focus on methodology and briefing of published reports from COTS group in COTS-1 study to highlight key messages from this large data.

PURPOSE: To analyze the role of polymerase chain reaction (PCR) of ocular fluids in management of tubercular (TB) anterior, intermediate, posterior, and panuveitis. METHODS: In Collaborative Ocular Tuberculosis Study (COTS)-1 (25 centers, n = 962), patients with TB-related uveitis were included. 59 patients undergoing PCR of intraocular fluids (18 females; 53 Asian Indians) were included. RESULTS: 59 (6.13%) of COTS-1 underwent PCR analysis. PCR was positive for Mycobacterium TB in 33 patients (23 males; all Asian Indians). 26 patients were PCR negative (18 males). Eight patients with negative PCR had systemic TB. Anti-TB therapy was given in 18 negative and 31 PCR cases. At 1-year follow-up, five patients with positive PCR (15.15%) and three with negative PCR (11.54%) had persistence/worsening of inflammation. CONCLUSIONS: Data from COTS-1 suggest that PCR is not commonly done for diagnosing intraocular TB and positive/negative results may not influence management or treatment outcomes in the real world scenario.

Purpose: To report early confirmation of Mycobacterium tuberculosis (MTB) endophthalmitis by detection of 85B mRNA in vitreous by a reverse transcriptase polymerase chain reaction (RT-PCR) technique.Methods: Retrospective, interventional case series of 5 patients with MTB endogenous endophthalmitis. Vitreous aspirate was subjected to Ziehl-Neelsen (ZN) staining, BACTEC MicroMGIT culture, RT-PCR targeting the 85B gene, real-time PCR targeting the IS6110 region, and nested PCR targeting the MPB64 gene and IS6110 region. Correlation between detection of MTB RNA, culture positivity, and ZN staining was studied.Results: Five patients with endophthalmitis with no history of tuberculosis revealed acid-fast bacilli on ZN staining of vitreous. RT-PCR detected 85B RNA within 24 h. Culture for MTB was positive in 3/5 patients after 1 month. None of the eyes recovered any useful vision.Conclusions: RT-PCR can detect viable MTB RNA and provide evidence of active infection much earlier than culture.

Fibroma is one of the most common soft tissue benign tumors of the oral cavity. These masses represent hyperplasias instead of true neoplasm, which develop due to irritation to the mucosal tissue resulting in proliferation of the cells. Although so common in the oral cavity, its occurrence on the palate is rare, mainly due to fewer chances of trauma. Here, we report a case of palatal fibroma in a child diagnosed on the basis of clinical, radiological, and histological features. The case represents an extremely rare occurrence as unusual trauma due to thumb sucking seemed to be the only apparent traumatic factor in the palatal region.

Frosted branch angiitis (FBA), a rare form of retinal vasculitis presenting as bilateral perivascular sheathing, resembling the appearance of frosted tree branches in winter, was first reported by Ito et al.1 in 1976, in a young immunocompetent boy. FBA predominantly affects healthy young patients, the youngest reported in an 11-month-old infant2 and oldest in a 42-year-old patient.3 Classical symptoms include sudden onset of blurred vision with floaters and photopsiae. Fundus examination shows widespread perivascular translucent sheathing affecting both arterioles and venules, more commonly latter. Fluorescein angiography shows late staining of vessels with no obstruction of blood flow. Electroretinogram shows reduced amplitude and visual fields show generalized constriction. Medline search did not show any case of frosted branch angiitis in a patient with typhoid fever.

Objective: To analyze the demographic profile, treatment, and visual outcome of the patients with sympathetic ophthalmia (SO) in a multicenter collaborative retrospective cohort study.Methods: Medical records of the patients with SO from UK, Singapore, India were reviewed for history of ocular trauma or surgery and subsequent development of uveitis consistent with SO, presenting symptoms, treatment, and visual outcomes.Results: A total of 130 patients were diagnosed with SO during the study period. Eighty-one (62.3%) patients were men. The mean age was 48.4 ± 15.5 years. The most common presenting symptom was blurring of vision (89.2%), followed by pain (29.2%) and floaters (23.8%). Ninety-two (70.7%) required additional immunosuppressive therapy. Thirty-six (27.9%) patients underwent enucleation of the inciting eye.Conclusions: SO is a potentially sight-threatening disease with high rates of visual loss. It warrants prompt evaluation and treatment. With the advances and availability in immunotherapy, the visual prognosis is relatively good.

PurposeTo report the clinical profile and role of perioperative adjunctive measures to reduce the risk of recurrence in Pythium insidiosum keratitis.MethodsRetrospective analysis of 10 eyes of 10 patients with P. insidiosum keratitis. Diagnosis was confirmed by PCR DNA sequencing.Results7out of 10 patients were from urban locales, and none had any obvious history of injury with vegetative matter and were being treated for fungal keratitis. 6 eyes presented with central full thickness infiltrates with subepithelial and superficial stromal infiltrates radiating in a reticular pattern. Corneal scraping in all eyes revealed sparsely septate fungal-like filaments on potassium hydroxide/Calcofluor. All eyes underwent the first therapeutic penetrating keratoplasty (TPK) based on worsening or non-responsiveness of clinical features to the antifungal regimen. Recurrence was noted in 7 out of 10 eyes of which 2 eyes underwent evisceration. Of the six eyes that underwent cryotherapy following confirmation of microbiological diagnosis of Pythium (along with primary TPK-1, with re-TPK-5), only one eye had a recurrence and had to be eviscerated. Of the two eyes that did not undergo cryotherapy during re-TPK, following microbiological diagnosis, one eye had a recurrence and had to be eviscerated. In two eyes with adjoining scleritis, the host bed was swabbed using absolute alcohol of which one eye was salvaged.ConclusionThis series highlights the need to be aware of this entity in the management of refractory fungal keratitis. It also brings to fore the adjunctive measures that could have a beneficial role in the management of pythium keratitis.

Corticosteroids form the mainstay of therapy for noninfectious uveitis. The anti-inflammatory and immunosuppressive action is mediated by controlling the protein synthesis both at cellular and molecular level. Corticosteroids in uveitis can be administered by topical, periocular, intravitreal, and oral routes. Long-term use of corticosteroids is associated with side effects such as hypertension, osteoporosis, hyperglycemia, Cushing’s syndrome, cataract, glaucoma, and others. Corticosteroid-sparing immunosuppressive agents form the next line of treatment in chronic, recurrent, and nonresponsive uveitis.

Background Fungal infection of the sclera is very rare. No case of fungal scleral abscess in a HIV-positive patient has been reported. We report a case of scleral abscess caused by Candida albicans and its successful resolution following antifungal therapy in a HIV-positive patient. Findings A 57-year-old diabetic Asian (Indian) who was on highly active antiretroviral therapy for the last 10 years presented with 2 weeks’ history of redness in his right eye. Examination revealed localised scleral inflammation with central ulceration in the inferior quadrant of the right eye. Initially, the ulcer scrapings revealed no microbial organism. Progression of ulcer although on empirical antibiotic therapy required repeat scrapings which showed Candida albicans species in culture sensitive to amphotericin and natamycin. Aggressive topical and systemic antifungals resulted in dramatic and complete healing of the ulcer in 3 weeks. Vision was well maintained at 20/30 throughout the treatment course, and the fundus remained normal. Conclusions This is the first ever case of fungal scleral abscess in a HIV patient to be reported emphasizing there is a need for high vigilance to suspect an infective aetiology of scleritis in patients with immunocompromised status. Prompt microbial assessment and appropriate antifungals can decrease morbidity in these unusual but serious cases as illustrated in this case.

Purpose: To describe the role of triple agent immunosuppression in severe recalcitrant cases of Vogt-Koyanagi-Harada syndrome. Materials and methods: Retrospective chart review of five cases of Vogt-Koyanagi-Harada syndrome. Results: All cases were treated with oral prednisolone, azathioprine, and cyclosporine in combination, and rapid remission was observed in all patients. The synergistic effect of the triple agent immunosuppressives helped in preventing recurrences. Prolonged treatment with steroid sparing immunosuppressives in severe and recalcitrant cases of Vogt-Koyanagi-Harada syndrome maintained disease remission. Conclusion: Severe cases of Vogt-Koyanagi-Harada syndrome can be treated with early use of high-dose triple agent immunosuppressives.

Purpose To describe a case of unilateral frosted branch angiitis in a patient with abdominal tuberculosis. Methods Observational case report. Results A 17-year-old girl with chronic abdominal pain, cough, and amenorrhea for 5 months presented with complaints of sudden diminution of vision in both eyes for 1 day. Fundus examination of the right eye showed disk edema, dilated tortuous vessels with perivascular sheathing (frosted branch angiitis), retinal hemorrhages, and macular edema. The left eye had areas of healed choroiditis. Duodenal biopsy showed features suggestive of tuberculosis. She was treated with antituberculosis therapy along with oral steroids after which the ocular condition responded dramatically. Conclusion Frosted branch angiitis can be a rare manifestation of intraocular tuberculosis.

Background: Elevated urinary albumin excretion and hormone therapy (HT) are associated with increased risk for cardiovascular events. We assessed the relationship between albuminuria and the use of hormonal preparations in postmenopausal women. Methods: Data from the Insulin Resistance Atherosclerosis Study were obtained at baseline and 5-year follow-up for analysis. The generalized estimating equation procedure accounting for repeated measures was used for this analysis. HT was the main predictor variable, and loge urine albumin-creatinine ratio (ACR) was the main outcome variable. Results: Four hundred ninety-one menopausal women were included in the analysis, 36% (n = 179) of whom received HT (either oral estrogen, progesterone, or combination therapy). At baseline, abnormal albuminuria (ACR ≥ 25 mg/g) was present in 11% of women on HT and 17% not on HT (P = 0.02). After adjusting for demographics, the presence of diabetes and hypertension, and kidney function, HT was associated with a 19% reduction in ACR (P = 0.008) and an odds ratio of 0.67 (95% confidence interval, 0.43 to 1.01; P = 0.06) for the presence of abnormal albuminuria. Other predictors of abnormal albuminuria included diabetes, blood pressure, and triglyceride level. Conclusion: Results of this study suggest that HT is associated with a reduction in urinary albumin excretion in postmenopausal women.

A 25-year-old male presented with visual loss in the right eye for 20 days and best-corrected visual acuity of counting fingers in the right eye and 20/20 in the left eye. The anterior chamber (AC) had old keratic precipitates, no AC reaction, dense vitritis, active multifocal retinochoroiditis, and retinal vascular sheathing in all quadrants. The left eye showed sheathed blood vessels with chorioretinal atrophy [Fig. 1]. Figure 1 (a) Color fundus montage of the right eye shows vitritis, vascular sheathing, and retinochoroidal infiltrates. (b) Enlarged view of multifocal retinochoroidal infiltrates with vitreous exudates in the right eye. (c) Color fundus montage of left eye showing ... The regular bacteriologic and viral investigations on the aqueous and vitreous samples were negative. ELISA for HIV 1 and 2 was positive. Rapid plasma regain (RPR) was reactive at a dilution of >1:32, and Treponema pallidum hemagglutination assay (TPHA) was positive at more than 1:1280 dilution [Table 1]. Table 1 Investigations carried out and their results The patient was started on tapering dose of oral steroids (1 mg/kg/day), antiretroviral therapy (tenofovir 300 mg, lamivudine 300 mg, and efavirenz 600 mg once daily). Intramuscular penicillin was administered for 3 weeks (2.4 million units every week). After 2 months, visual acuity improved to 20/30, and vitreous inflammation cleared leaving behind retinal pigment epithelium mottling [Fig. 2]. Figure 2 Color fundus montage picture of the right eye showing resolution of vitritis and retinochoroiditis with retinal pigment epithelium mottling 2 months following initiation of treatment

ObjectiveTo determine the clinical experience of using combined-modality [simultaneous hemodialysis (HD) and peritoneal dialysis (PD)] treatment in patients with end-stage renal disease.DesignWe reviewed data on 4 patients from our center that were treated with “combined-mode therapy.” We then conducted a retrospective survey by sending questionnaires to nephrologists in the US and Canada by mail and by posting the survey on the Internet. Data queried included number of patients on combined modality, solute clearances, albumin levels pre and post combined therapy, reasons for using combined therapy, duration and success of combined therapy, and reimbursement issues.Setting and ParticipantsOurs is a tertiary-care center. Patients that were not doing well on PD alone were put on combined modality of treatment between 1992 and 1998.Main Outcome MeasuresClinical improvement in the indication for which the participant was started on combined modality.ResultsIn response to the survey, data on 27 patients were collected. These data were combined with data on 4 patients from our unit that had previously been treated with combined HD and PD. Most patients were reported to have more than one clinical reason for changing from PD to combined therapy. The main clinical reason for offering combined treatments was inadequate solute clearance (34%), followed by ultrafiltration problems (16%) and neuropathy (11%). Mean duration of time followed on combined treatment was 8.5 ± 0.12 months. Most patients tolerated combined treatment well and were reported to show improvement in the clinical reasons for which they needed the combined modality. Dual access and reimbursement issues were not a problem. There was no single method used for calculating total (HD, PD, and residual renal) solute clearance. No universal total solute clearance goal was reported.ConclusionHemodialysis and PD are not mutually exclusive. They can be used in combination to achieve targeted solute clearances, to improve certain clinical conditions, and to control volume and blood pressure in a subset of patients. Further evaluation is needed to better establish the long-term outcomes of using combined modality. Total solute clearance goals and methods for determining total solute clearance need to be standardized.

Bacterial co-infections have been reported in association with dengue fever (DF) and can exacerbate dengue infections. However, DF with acute respiratory distress syndrome and co-infection with Alcaligenes faecalis (A. faecalis) has not been reported earlier. Most infections caused by A. faecalis are opportunistic. Urinary tract infection, bacterial keratitis, postoperative endophthalmitis, skin and soft tissue infections, bacteremia, meningitis, wound infections, and peritonitis in patients undergoing peritoneal dialysis have been described in association with A. faecalis. A. faecalis, a Gram-negative environmental organism rarely cause significant infections. Treatment can be difficult in some cases due to the high level of resistance to commonly used antibiotics. We report a case of fatal bronchopneumonia caused by extensively drug resistance A. faecalis in a patient of dengue hemorrhagic fever.

Hydrotropes, such as sodium toluate, sodium toluene sulfonate, sodium cymene sulfonate, sodium mesitylene sulfonate, and sodium pseudocumene sulfonate, have been investigated for their effectiveness in separations of close boiling point mixtures, such as p -cresol/2,6-xylenol and phenol/ o -chlorophenol. The effect of various parameters, such as the structure of the hydrotrope, concentration of the hydrotrope, nature of the solvent, and composition of the mixtures, on separation efficiency has been studied. The separation factor increases with the concentration and the hydrophobic parameters, such as the surface area and the molar volume of the hydrophobic parts of the hydrotropes. A polar solvent gives poor percentage extractions and in some cases lower separation factors than those obtained with inert solvents.

Hereditary angioedema (HAE) is a debilitating disorder that can substantially impair quality of life. Three types of HAE are described in literature. Women are particularly prone to attacks due to multiple estrogen-related triggers. Abdominal involvement in angioedema is often a challenge to diagnose. Recurrent or acute onset abdominal pain can be the only presenting symptom, and misdiagnosis may lead to unnecessary surgical intervention. Clinicians need to be familiar with the types and presentations of the various types of angioedema. The knowledge about new, effective, and safe therapies, along with an increased awareness of HAE and its related concerns should help clinicians in providing optimal treatment to their patients and avoid unnecessary surgical interventions. We report a sporadic nonfamily case of HAE type III presenting as recurrent abdominal pain with intestinal obstruction in women with primary infertility.

PURPOSE To report a rare case of live intraocular Dirofilaria causing anterior uveitis and multifocal choroiditis. METHOD Observational case report. RESULT A 43-year-old, healthy, Asian Indian woman presented with complaints of pain, redness, floaters, and decreased vision in the right eye. Slit lamp examination revealed a vigorously moving live intraocular worm in the anterior chamber. Indirect ophthalmoscopy showed active multifocal choroiditis in the posterior pole with retinal pigment epithelial tracts and chorioretinal scars in the periphery. Surgical removal of the worm from the anterior chamber was done immediately. The patient was then treated with diethylcarbamazine citrate along with topical steroids. CONCLUSION In endemic countries, in a patient with multifocal choroiditis, one should look for retinal pigment epithelial tracts in the retina to rule out parasitic infestation like Dirofilaria. Careful examination, prompt diagnosis, and early treatment can reduce ocular morbidity.
