Introduction: Corneal infection is one of the major causes of monocular blindness in developing countries.

Purpose: To describe the prevalence, characteristics including risk factors, and pattern of severe ROP from eastern Madhya Pradesh region of India. Methods: In this 5-year retrospective study, Baseline characteristics, systemic risk factors, and findings of ROP screening were noted. Factors associated with severe ROP including aggressive posterior ROP (APROP), stage IV and V ROP were analyzed. Statistical analysis was done using SPSS version 20. Results: Of 763 babies screened, 30% were diagnosed to have ROP. Prevalence of severe ROP was 14.2% (109) of which 60 (55.5%) were classic and 30 (27.7%) were APROP. Eighteen (16.6%) were diagnosed as advanced ROP (stage IV and V). Mean gestational age (GA) and birth weight (BW) for severe ROP were 31.05 weeks and 1.34 kg, respectively which were inversely associated with severe ROP. But a significant 10% of severe ROP were seen in late preterm babies, >34 weeks. Low GA and respiratory distress syndrome (RDS) were significant risk factors for APROP. Most important factor for stage IV and V ROP was late presentation for screening. Conclusion: The study found a high prevalence of severe ROP including APROP. Almost 7% severe ROP cases were outside screening guidelines of NNF. Late presentation for screening is the most important factor associated with ROP related blindness.

Ophthalmomyiasis is the infestation of human eye by the larvae of certain flies. Sheep botfly commonly manifests as Ophthalmomyiasis externa when there is conjunctival involvement or rarely as Opthalmomyiasis interna when there is larval penetration into the eyeball. It appears to be more common than what has been indicated by previously published reports. We present a report of seven cases of Ophthalmomyiasis by Oestrus ovis, from central India who presented with features of conjunctivitis varying between mild to severe. The larvae were seen in bulbar and palpebral conjunctiva and also entangled in lashes with discharge. Since the larvae are photophobic, it is prudent to look for them in the fornices and also in discharge. Prompt removal of the larvae from the conjunctiva helps in relieving the symptoms and also prevents serious complications. Taxonomic identification of the species is important to estimate the risk of globe penetration by the larvae.

Background and Aim:The extensive use of antimicrobials in poultry has led to an increase in bacterial multidrug resistance, and the emergence of multidrug-resistant nontyphoidal Salmonella is a global problem. This study was performed to detect antibiotic-resistant Salmonella serovars in poultry farming and processing environment.Materials and Methods:A total of 956 various samples, comprising 432 farm origin, 324 poultry processing stage wise and environmental, and 154 product processing stages and environmental samples, were collected from poultry farms and processing units located in and around Mumbai city. Of a total of 71 recovered isolates, 42 randomly selected Salmonella isolates were subjected for antibiotic susceptibility testing by disk diffusion method and serotyping. A total of 31 serotypically confirmed isolates were characterized for the presence of tetA, tetB, blaTEM, and CTX-M gene.Results:Higher resistance was recorded against Doxycycline (100%), followed by Oxytetracycline (97.62%), Neomycin (88.10%), Erythromycin (83.33%), Tetracycline (78.57%), and Ceftizoxime (35.71%). Resistance from 0.00 to 26.19 percent was found to antimicrobials, namely Norfloxacin (26.19%), Ampicillin (21.43%), Azithromycin (21.43%), Ciprofloxacin (19.05%), Colistin (4.76%), Streptomycin (16.67%), Cefotaxime (14.19%), Enrofloxacin (14.29%), Amoxyclav (14.29%), Gentamicin (7.14%), Chloramphenicol (4.76%), Amikacin (4.76%), and Ceftazidime (0.0%). Results demonstrate that the Salmonella Virchow dominated and all serotypes were found to carry Tetracycline resistance gene tetA, 5 isolates were found to be positive for blaTEM, whereas none of the isolates were carrying tetB and CTX-M gene.Conclusion:This study revealed that there is a significant rise of Tetracycline resistance with the presence of tetA gene in Salmonella spp. which indicates selective pressure for adopting resistance against tetracycline group of antibiotics.

Street foods are one of the important sources of foodborne infections and Staphylococcus aureus is an important infectious agent transmitted through various sources including street foods. The methicillin-resistant S. aureus (MRSA) are of public health significance, hence the study was taken to assess the street foods as a source of MRSA, for which 430 street vended foods of animal origin (meat, milk, eggs and their products) and associated environmental samples were processed for isolation and characterization. A total of 52 (12.1%) S. aureus were isolated and resistant was observed to oxacillin (36.5%), cefoxitin (25%) and penicillin G (82.7%) by disc diffusion test. On genotypic screening, mecA and blaZ have detected in 17.3% and 69.2% isolates, respectively. The virulence typing identified nuc, coa, clfA, spA, FnbA and enterotoxin A (sea) genes in 100%, 96.2%, 30.8%, 55.8, 50% and 7.7% isolates, respectively. Genetic diversity among the isolates was observed by enterobacterial repetitive intergenic consensus PCR with a D value of 0.77. The presence of virulent MRSA in street vended foods trigger the public health concern and emphasis to educate the consumers and street food vendors about quality and safety of such foods.

Dislocation of intraocular lens (IOL) is a serious complication of blunt ocular trauma in pseudophakic eyes. Here, a 72-year-old male patient with subconjunctival dislocation of an IOL (pseudophacocele) secondary to bull horn injury was reported. In this case report, a new sign named as “golden half ring sign” was described for easy identification and localization of subconjunctival dislocation of IOL in patient with open globe injury (surgical wound dehiscence) associated dense subconjunctival hemorrhage.

This study demonstrated that frequency of GCB subtype of DLBCL is significantly higher than the non-GCB subtype, and the non-GCB immunophenotype has better relapse-free survival 78% (standard error = 0.10) at the end of 3 years, while GCB has 56% (standard error = 0.23). Further studies should be performed with larger number of patients to show difference in clinical outcome between GCB and non-GCB subgroups.
