The purpose of this study was to investigate whether sporulated Neospora caninum oocysts, which had been stored for 46 mo in a 2% sulfuric acid solution at 4 degrees C, remain morphologically viable and infective to gerbils (Meriones unguiculatus). Six gerbils were orally inoculated with doses of 400 or 1,200 oocysts. Two mo after inoculation, the animals did not show any clinical signs, had no histological lesions, and were seronegative for N. caninum at 1: 50 in an immunofluorescent antibody test. PCR using the brain from each gerbil did not reveal N. caninum specific DNA. We conclude that oocysts preserved for 46 mo are not infective, despite being morphologically intact.

Introduction: The emergence of methicillin-resistant Staphylococcus aureus (MRSA) is a challenge in the management of skin and soft tissue infections (SSTIs). Objective: To describe the epidemiology of MRSA SSTIs among admitted patients at the University of Santo Tomas Hospital (USTH). Methods : This was a retrospective study of inpatients with MRSA SSTIs from 2011-2015. MRSA infections were classii ed as community-associated (CA-MRSA) and healthcare-associated (HA-MRSA). Demographic characteristics, clinical proi le, comorbidities, complications, risk factors, antibiotic susceptibility and resistance, treatment used, and clinical outcome were determined. Results: Out of the 331 inpatients with Staphylococcus aureus SSTIs, 211 had MRSA with a prevalence of 63.7%, 80.1% of MRSA were CAMRSA while 19.9% were HA-MRSA. The mean age was 41.58 years with male predominance. The majority presented with abscess (62.9%), on the legs (21.8%). The abscess was signii cantly associated with CA-MRSA while infected wounds, previous hospitalization, and surgery were correlated with HA-MRSA. Growing resistance to ciprol oxacin, tetracycline, macrolides, co-trimoxazole, and clindamycin was noted. A low percentage of resistance to vancomycin and linezolid was observed. Almost all cases improved with appropriate antibiotic therapy and 3.3% mortality Conclusion More than half of the patients with Staphylococcus aureus SSTIs had MRSA. and were mostly CA-MRSA and males. Abscess on the leg was the common presentation and signii cantly associated with CA-MRSA. Infected wounds, previous hospitalization, and surgery were associated with HA-MRSA. There was high resistance of MRSA to ciprol oxacin and tetracycline while low resistance to vancomycin and linezolid. Almost all improved with appropriate treatment.

Objectives: To do report the incidence of capsular changes in Crystalens-implanted eyes and analyze the indications and outcomes of yag capsulotomy. Methods: We reviewed the records of 411 eyes of 258 patients implanted with the Crystalens IOL. Capsular change indications for yag capsulotomy were posterior capsular opacification (PCO), lens tilt, and capsular striae. Eyes in each indication were further subdivided into therapeutic yag (TY) and prophylactic yag (PY) groups. Outcomes before and after yag capsulotomy were analyzed. Results: Ninety of 411 crystalens-implanted eyes (22%) had undergone yag capsulotomy. Sixty-one eyes had PCO, 12 had lens tilt, and 17 had striae. Twenty-seven eyes belonged to the therapeutic (TY) and 63 eyes to the prophylactic (PY) yag subgroups. The mean interval between phacoemulsification and yag capsulotomy was 10 months. In the TY PCO subgroup, uncorrected distance visual acuity (UDVA) changed from 20/40 pre-yag to 20/25 post-yag, uncorrected near visual acuity (UNVA) from J3 to J2, manifest refraction spherical equivalent (MRSE) from -0.43D to -0.2D. In the TY tilt subgroup, UDVA changed from 20/50 to 20/30, UNVA was unchanged at J2, and MRSE from -1.21D to -0.89D. In the TY striae group, UDVA changed from 20/50 to 20/30, UNVA from J3 to J2, and MRSE from 0.62D to -0.4D. In the PY PCO subgroup, UDVA was unchanged at 20/25, UNVA unchanged at J2, and MRSE changed from -0.52D to -0.47D. In the PY tilt subgroup, UDVA changed from 20/25 to 20/20, UNVA unchanged at J2, and MRSE changed from -0.87D to -0.45D. In the PY striae subgroup, UDVA was unchanged at 20/30, UNVA changed from J3 to J2, and MRSE changed from -0.62D to -0.7D. Conclusion Capsular changes occurred after Crystalens implantation that necessitated yag capsulotomy. Once vision has deteriorated, a therapeutic yag treatment can help improve vision. If capsular changes have occurred but vision has not deteriorated, a prophylactic yag capsulotomy can stabilize visual and refractive outcomes.
