Outcomes of therapeutic penetrating keratoplasty in 198 eyes with fungal keratitis

Purpose: To study the outcomes of therapeutic penetrating keratoplasty in fungal keratitis. Methods: This retrospective, observational, interventional case series involved an audit of 198 consecutive eyes that underwent therapeutic penetrating keratoplasty (ThPK) for fungal keratitis at L V Prasad Eye Institute between January 2008 and December 2010 was performed. The data on demographics, clinical characteristics, intraoperative, and late postoperative complications were noted. The primary outcome measure was eradication of infection and postoperative anatomical success. Secondary outcome measures were graft survival, risk factors, clinical features, and management of recurrent fungal keratitis post ThPK. Results: Mean follow-up after ThPK was 24 ± 17 months. A total of 178 (89.9%) eyes had complete eradication of fungal infection, whereas 20 (10.1%) eyes developed recurrence. Anatomical restoration was achieved in majority of cases (192 eyes; 97%). Larger infiltrate size was associated with a higher risk of recurrence of infection. The median graft survival rate was 5.9 months. The graft survival was better for grafts <8 mm versus those with >8 mm (P = 0.026) and not found significantly related to the species of fungus. Twenty-seven eyes underwent re-grafting: penetrating keratoplasty in 14 eyes, and Descemet's stripping endothelial keratoplasty in 13 eyes. Conclusion: As larger infiltrate prior to therapeutic keratoplasty had much higher risk of recurrences; timely surgical intervention should be considered in cases not responding to medical therapy. Alternative strategies of management of postoperative inflammation need to be considered to prevent graft failures.

Procurement, storage and utilization trends of eye banks in India

Purpose: To study the trends in collection, storage and utilization of donor corneas in eye banks in India. Methods: The data was collected from 12 eye banks in India that collected more than 1000 corneas per year. The retrospective analysis of the parameters like characteristics of the donor and the host, storage media used, number of eyes collected, number of eyes utilized, causes of non-utilization of the tissue and the procedures performed was done. Results: A total of 20,564 eyes were collected by the 12 eye banks during the year 2013–2014. Voluntary eye donation (VED), and hospital cornea retrieval program (HCRP) contributed to 59.6% and 40.4% of tissue procurement respectively. Whole globe enucleation (52.3%) was more commonly performed as compared to in-situ excision of the donor corneas. The most commonly used storage media at all eye banks was McCarey-Kaufman (MK) media (83.3%). The utilization rate of the donor eyes was 50.5%. The most frequent indication for corneal transplantation was infection (active infection - 33.13%, healed infection - 10.78%) followed by Pseudophakic bullous keratopathy (PBK) (13.57%). Full thickness keratoplasty (optical penetrating keratoplasty - 47.23%, therapeutic penetrating keratoplasty - 31.74%) was performed most often followed by endothelial keratoplasty (12.41%) in the developing country. Conclusion: VED still contributes to majority of the donor tissue retrieval in India. The majority of the eye banks still utilize whole globe enucleation technique and store tissues in MK media. Trends from previous years showed a change towards HCRP, in-situ excision technique and preservation in the long-term storage media.

A prospective study of efficacy of ultrasound guided transversus abdominis plane block for postcesarean analgesia

Background: The ultrasound guided transversus abdominis plane (TAP) block which provides effective analgesia after lower abdominal surgeries including caesarean section. It is a simple and reliable technique. In this prospective, randomized double-blind study, we determined the efficacy of TAP block using 0.25% Bupivacaine and 0.9N Saline with respect to VAS for pain, postoperative Tramadol consumption and post-operative ondansetron usage.Methods: This study was conducted on 100 adult patients of ASA physical status I and II in the   age group of 18 to 40 years undergoing elective lower segment cesarean section under spinal anaesthesia. Study group received TAP block with 0.25% Bupivacaine and control group received 10 ml of 0.9N saline on each side. Patients were analyzed for postoperative pain by pain score (at rest, on movement, on cough) using VAS was recorded at 0, ½, 1, 2, 4, 6, 12 and 24 hours postoperatively. Need for rescue analgesia was assessed by time to first dose of Tramadol requirement and total dose of Tramadol over 24 hours of postoperative period. Ondansetron (4 mg i.v.) was administered whenever nausea score was more than 2 or the patient vomited. All the data was noted using uniform performs.Results: Patients received TAP block with 0.25% Bupivacaine had better pain scores at first hour of postoperative period during rest, cough and movement which was statistically significant (p<0.0010) in comparison to group B. There was a statistically significant difference (p <0.001) in the requirement of total dose of Tramadol as a rescue analgesia in patients who received transversus abdominis block with 0.25% Bupivacaine (138.77 mg) in comparison with other group(240 mg).The mean time to first request for Tramadol was significantly longer in group A (5.8 hrs)  in comparison to group B (1.93 hrs) with p value <0.001. Patients received TAP block with 0.9N saline needed more dose of Ondansetron, however, the difference was not statistically significant (p >0.001).Conclusions: TAP block using ultrasound provides substantial reduction in Tramadol consumption, time to first dose of rescue tramadol when compared with control group. This study reinforces the recommendation for TAP as a part of multimodal post-operative analgesic regimen.

Primary graft failure after big bubble deep anterior lamellar keratoplasty in macular corneal dystrophy

Macular corneal dystrophy is autosomal recessive dystrophy characterized by deposits of abnormal glycosaminoglycans in stromal lamellae and within endothelial cells. Deep anterior lamellar keratoplasty is successful in the management of this dystrophy. We herein describe three cases of primary graft failure after uneventful big bubble deep anterior lamellar keratoplasty for macular corneal dystrophy.

Ocular infections caused by Candida species: Type of species, in vitro susceptibility and treatment outcome.

Purpose: To report clinical and microbiological profile of patients with ocular candidiasis. Materials and Methods: Patients with ocular candidiasis were retrospectively identified from microbiology records. Significant isolates of Candida species were identified by Vitek 2 compact system. Minimum inhibitory concentration (MIC) of antifungal agents such as amphotericin B, itraconazole, voriconazole, fluconazole and caspofungin was determined by E test and of natamycin by microbroth dilution assay. Data on treatment and outcome were collected from medical records. Results: A total of 42 isolates of Candida were isolated from patients with keratitis-29, endophthalmitis-12 and orbital cellulitis-1. The most common species isolated was Candida albicans (12-keratitis, 4-endophthalmitis, 1-orbital cellulitis). All except one isolate were susceptible to amphotericin B. MIC of caspofungin was in the susceptible range in 28 (96.5%) corneal isolates while 12 out of 29 (41.3%) corneal isolates were sensitive to fluconazole. Resistance to voriconazole was seen in four corneal isolates. All isolates were susceptible to natamycin and all except two isolates were resistant or susceptible dose-dependent to itraconazole. Outcome of healed ulcer was achieved in 12/18 (66.6%) patients treated medically, while surgical intervention was required in 11 patients. Among the isolates from endophthalmitis patients, 11/12 were susceptible to amphotericin B, 6/12 to voriconazole and all to natamycin. Ten out of 11 patients (one patient required evisceration) with endophthalmitis were given intravitreal amphotericin B injection with variable outcome. Conclusions: Ocular candidiasis needs early and specific treatment for optimal results. Candida species continue to be susceptible to most commonly available antifungals including amphotericin B, voriconazole and natamycin.

Correlation and Path Coefficient Analysis in Kabuli Chickpea (Cicer Arietinum L.)

Thirty genotypes of kabuli chickpea were used to study the extent of genetic variability, correlation and path analysis for yield and yield contributing characters. Wider genetic variability with high heritability and high genetic advance as per cent of mean was recorded for number of primary branches per plant, biological yield per plant and seed yield per plant. Correlation studies revealed that seed yield was significantly and positively correlated with plant height, number of primary branches per plant, number of secondary branches per plant, number of pods per plant, 100-seed weight, harvest index and biological yield per plant. Path coefficient analysis indicated that biological yield per plant, number of pods per plant and harvest index had high positive direct effect on seed yield signifying the importance of these traits in improvement of seed yield.

Child Abuse By Burns - A Case Report.

Child maltreatment happens in all countries and in families of all racial and religious groups. There are four major types of abuse: physical abuse, sexual abuse, emotional abuse and neglect. Cutaneous injury is the most common injury caused by abuse. Cutaneous manifestations of physical abuse include bruises, lacerations, abrasions, burns, oral trauma, bite marks and traumatic alopecia. Abuse by burning comprises approximately 6% to 20% of all child abuse cases. Proper evaluation is necessary, because the use of cultural practices does not exclude the potential for child abuse. A 3 year old boy reported with extra oral swelling over the right side of the submandibular region. On clinical examination the boy had well demarcated burn marks at right and left side of submandibular regions. Treatment for lymhadenitis and burnt region was carried out and case reported to psychiatry department for counseling. It is recommonded that the offering of community child abuse educational progrmmes for all professionals including dental professionals, psychiatry, medicine, allied health,nursing, social workers and schools of education by providing literature, posters and handouts

Ovarian hemangioma with stromal luteinization and HCG-producing mononucleate and multinucleate cells of uncertain histogenesis: A rare co-existence with therapeutic dilemma.

A 21 year old female presented with amenorrhea, hirsutism and change in voice along with an elevated serum β-HCG (human chorionic gonadotrophin) level and normal CA-125 level. Laparotomy revealed an enlarged right ovary measuring 6 × 5 × 1 cms with presence of an ovarian hemangioma along with stromal luteinization and HCG producing mononucleate as well as multinucleate cells of uncertain histogenesis on histopathological examination. Immunohistochemistry for inhibin and calretinin were positive in the luteinized component whereas β-HCG and Ki-67 were positive in the multinucleate cell component. The diagnostic rarity and therapeutic dilemma of such a rare mixed tumor within a single ovary has proven to be an exceptional case and an excellent investigative opportunity.

CALLA negative precursor B lymphoblastic leukemia with MLL gene translocation and an unusual FISH signal pattern.

Rearrangements of the mixed lineage leukemia (MLL) gene at 11q23 commonly occur in infants with CALLA negative B lymphoblastic leukemia (B-ALL). Most often, these are detected by conventional karyotyping; however, fluorescent in-situ hybridization (FISH) with the help of a dual-color break-apart probe is used to identify cryptic translocations. When there is an MLL gene translocations the usual FISH signal pattern is 1 red-1 yellow fusion signal pattern We present a case of an infant with CALLA negative precursor B-ALL with a characteristic translocations t(4;11) (q21;q23),however,with an unusual MLL FISH signal pattern.

Immunogenicity and safety of Abhay M and M-vac vaccines in healthy infants: a phase III multicentric randomized single blind trial.

OBJECTIVE: To study immunogenicity and safety of Abhay M and M-Vac vaccines in prevention of measles in healthy infants. METHODS: In a randomized, single blind, comparative, multi-centric phase III trial, a total of 600 healthy infants between 9 - 15 months of age were recruited in the study from seven participating sites during five months. The block randomization design was used for randomizing the subjects into 2 vaccine groups (Investigational Vaccine - Abhay M and Control Vaccine - M-Vac) in the ratio 2:1. At base line (visit 1) a venous blood sample 1.5 ml was collected and subjects were then administered a single dose 0.5 ml of measles vaccine (Abhay M or M-Vac vaccine) subcutaneously according to randomization. Following administration of vaccine, subjects were observed closely for 30 - 60 minutes at the study hospitals for local reactions and systemic events. At visit 2 (follow up visit) another venous blood sample 1.5 ml was collected and the paired sera (both pre and post vaccination serum) were tested concurrently. Safety and immunogenicity were assessed through follow-up of adverse events and anti measles antibody response respectively. RESULTS: Overall 95.7 % seroconversion was achieved in both the groups, 96% in Abhay M vaccine group and 95.1%. in M-Vac vaccine group. There were no statistically significant differences in the observed seroconversion rates. In Abhay M vaccine group, the pre vaccination geometric mean titers (GMT) significantly increased from 35.5 mIU/ml to 486.9 mIU/ml after vaccination. The observed significant increase of GMT in M-Vac vaccine group was from 33.3 mIU/ml to 375.8 mIU/ml. Overall 459 (82.5%) out of 556 subjects were seroprotected after vaccination i.e. > or equal to [corrected] 200 mIU/ml (Protective levels). Of the 459 seroprotected, 315 (84.9%) subjects were in Abhay M vaccine group and 144 (77.8%) subjects were in M-Vac vaccine group. The frequencies of the reported local and general symptoms were similar between the Abhay M vaccine group and M-Vac vaccine group. CONCLUSION: Human Biologicals Institute's Abhay M vaccine is equally immunogenic and as safe as M-Vac vaccine when administered to healthy infants in single dose schedule.

Undifferentiated sarcoma of the mitral valve with secondaries in brain in a girl of 22 years.

During a mitral valve replacement surgery in a girl of 22 years of age, it was accidentally discovered that the valve was destroyed due to a tumor and the histopathology and immunohistochemistry findings have proved it to be undifferentiated sarcoma. She was advised by the surgeon to go for chemotherapy. There was a delay of three months from the side of the patient to reach us and during that interval she has developed secondaries in the brain. This case is being presented here for its rarity.

A 25-year-old multiparous female presented with fever, joint pains, facial rash and lymphadenopathy of three months' duration. Lymph node biopsy revealed a diagnosis of Kikuchi's disease. She fulfilled seven out of the 11 ARA criteria for SLE. The association of Kikuchi's disease and SLE is rare.

Role of free radicals and antioxidants in tuberculosis patients.

Background: Severe oxidative stress has been reported in TB patients because of malnutrition and poor immunity. The purpose of this study was to investigate the serum lipid peroxidation products and important free radical scavenging enzymes i.e. superoxide dismutase (SOD), catalase and antioxidant glutathione levels and total antioxidant status in TB patients. Methodology: The subjects for this study comprised of normal human volunteers (NHV,n=25), TB patients (n=100) – including untreated (TB1, n=55), under treatment (TB2, n=30) and after treatment (TB3, n = 15) with anti-tuberculosis therapy (ATT). Results: The levels of lipid peroxidation products malondialdehyde (MDA) were increased significantly in TB1 & TB2 (P<0.001) and also in TB3 (P<0.01); these levels gradually decreased with clinical improvement with ATT. SOD, catalase, glutathione levels and total antioxidant status were decreased significantly in TB1 & TB2 (P<0.001), TB3 (P<0.01) patients in comparison with NHV, these levels gradually increased with clinical improvement with ATT. Oxidative stress was observed in all the TB patients (TB1, TB2, TB3), irrespective of treatment status. Conclusions: The study showed that in TB patients free radical activity is quite high and antioxidant levels are low. A suitable antioxidant therapy may prove beneficial and nutritional antioxidant supplementation may represent a novel approach to fast recovery.
