The role of viral infections in ocular pathology varies greatly, involving all the components of the eye. Some viruses like herpes simplex, herpes zoster, adenovirus, enterovirus 70, influenza virus, human immunodeficiency virus, and cytomegalovirus are well-known for their role in ocular pathology. In recent years, emerging and resurging viral infections represent an important public health problem. The Asia-Pacific region has witnessed a number of pandemic and epidemic outbreaks caused by these viruses during the last 2 decades. The number of ocular complications being reported in patients of these viral infections has also increased significantly during this period. Ophthalmologists and physicians should be aware of ocular manifestations of newly emerging or resurging viral diseases. We conducted a review of the literature published during the last 20 years with the objectives of finding out outbreaks of emerging and reemerging viruses in the Asia-Pacific region and finding out any ocular involvement in these viral infections. An iterative search of the MEDLINE and the Google databases was made using the search terms emerging virus, ocular manifestations, ocular complications, Chikungunya, Dengue, Japanese encephalitis, West Nile fever, Kyasanur forest disease, Rift valley fever, Hantavirus, Henipavirus, Influenza virus, Enterovirus 71, and Asia-Pacific region, separately and with reported ocular involvement in combination. This review article discusses the epidemiology and the systemic and ocular manifestations of all emerging viral infections with reported ocular involvement in the Asia-Pacific region.

Background:The infections caused by metallo-beta-lactamases (MBLs) producing Pseudomonas aeruginosa are associated with higher rates of mortality, morbidity, and overall healthcare costs compared to non-MBL P. aeruginosa infections.Purpose:To compare the epidemiologic factors and antibiograms of MBL-positive and MBL-negative P. aeruginosa isolates in a tertiary care hospital.Methods:In an observational study, from January 2011 to December 2012, all non-duplicate P. aeruginosa isolates were subjected to an antimicrobial sensitivity test against 10 antibiotics of five different classes. All P. aeruginosa strains showing resistance to at least one of the carbapenems were subjected to the MBL-E test. Epidemiological features and antibiograms of MBL-positive and MBL-negative strains were compared and statistically analyzed.Results:Out of 350 isolates (total sample = 5330) of P. aeruginosa, MBL was detected in 58 isolates by the E-test, resulting in a prevalence of 16.57%. Resistance to most of the antibiotics was significantly higher in the MBL-positive strains with 100% resistance to ciprofloxacin, tobramycin, and meropenem, followed by imipenem (93.10%) and gentamicin (89.66%). The prevalence of multidrug-resistant and pandrug-resistant strains was significantly higher among the MBL group as compared to that in the non-MBL group ((55.17 vs. 7.88% (P < 0.0001) and 8.62 vs. 0.68% (P = 0.0006)), respectively.Conclusions:MBL-positive P. aeruginosa strains showed very high resistance to various antibiotics, as compared to the non-MBL strains. Increasing prevalence of MBL-producing isolates in hospital settings makes it important to perform routine detection of MBL-positive P. aeruginosa strains by in vitro testing before antibiotic use, for the purposes of infection prevention, and control, and for minimizing the adverse outcomes of infections with MBL-producing strains.

Background: There are only few studies on the clinico-demographic profile of acute and transient disorders, which is a common disorder in developing countries. Objective: To study the clinical presentation and socio-demographic profile of patients with Acute and transient psychotic disorders. Methods: Thirty patients diagnosed as Acute and transient psychotic disorders were assessed to record their socio-demographic profile, presence of stress, onset, presenting complains and the phenomenology using standard questionnaire. Results: ATPDs was more common in persons below thirty years of age (63.3%), residing in rural areas (90%), unemployed (76.7%), low middle socioeconomic status (53.3%), married (63.3%), and member of nuclear family (63.3%). Abrupt onset was seen in 73% of cases. Delusion of persecution was the most common psychopathology (86.7%). All patients had impaired biorhythm and poor insight. Conclusions: Married unemployed persons below the age of thirty of low middle socioeconomic status residing in nuclear families in rural areas suffer from ATPDs more than others.
