We describe a technique for performing safe phacoemulsification of a Morgagnian cataract using the intraocular lens (IOL) scaffold. An IOL scaffold has been used in cases in which posterior capsule rupture has occurred, leaving nonemulsified nuclear pieces. The scaffold provides a barrier that prevents the nuclear fragments from falling posteriorly into the vitreous cavity. Our technique uses the IOL as a scaffold to prevent the vulnerable posterior capsule from rupturing during nuclear emulsification in Morgagnian cataract...

BACKGROUND: In Australia, more than 20% of women giving birth are 35 years or older. Advanced maternal age (AMA) is a risk factor for stillbirth, and many clinicians now recommend induction of labour (IOL) at around term gestation. The aim of this study is to determine if AMA is associated with emergency caesarean section (CS) following IOL. METHODS: A retrospective cohort study was undertaken using routinely collected de-identified data. Live-born, singleton, cephalic, non-anomalous pregnancies undergoing IOL between 37 + 0 and 42 + 0 weeks were included...

Opacification of a hydrophilic acrylic intraocular (IOL) lens is a rare phenomenon. We herein report a case of a 57-year man complaining of decreased vision at left eye for the last 4 months. He had undergone phacoemulsification with IOL implantation 2 years back. IOL opacification was observed through slit-lamp. IOL exchange was carried out. The exchanged IOL and a new lens of the same model were sent to laboratory for pathologic analysis. Confocal microscopy showed uniformly distributed granules from the surface to 80 µm internal surface...

BACKGROUND: Lipoma is the most common benign tumour of the human body, being intraosseous involvement very rare. Just 1 to 4% of all cases of lipoma are located in the oral cavity, only 0.1% being intraosseous. The jaw is its most uncommon bone location. Etiology of intraosseous lipoma (IOL) is unknown, although several theories have been proposed. Usually asymptomatic, the symptoms, when present, will depend on its location and size. Its origin may be intraosseous or juxtacortical. A biopsy is essential for diagnosis, and definitive treatment involves resection or curettage of the lesion...

Polydimethylsiloxane (PDMS) constitutes an interesting material for a variety of biomedical applications, especially as intraocular lenses (IOLs), for its excellent transparency. In this work, a photoreversible PDMS-coumarin network, whose shape and properties can be adjusted postoperatively in a noninvasive manner, is developed. The synthesis of PDMS-coumarin is achieved by amidation of a coumarin acid chloride derivative with amine-functionalized PDMSs. Under exposure of λ > 300 nm, these polymers can be cured by dimerization of coumarin...

To present a combination technique for two cases of in-the-bag intraocular lens (IOL) luxation into the vitreous cavity. Vitrectomy was performed via a cornea microincision vitrectomy system, and the luxated IOL was fixed into the sclera. IOL fixation is simple from no trocar cannulas and less disrupted conjunctiva. Postoperative corneal endothelial cell density in Case 1 and Case 2 were reduced by -2.1% and -5.1%, respectively. Postoperative frequency of hexagon was decreased in Case 1 but maintained in Case 2...

RATIONALE: Although transscleral-fixated intraocular lens (IOL) implantation has been the most frequently chosen treatment for patients with inadequate capsule support, the ghost pupillary capture phenomenon did not cause enough attention. PATIENT CONCERNS: We present an unusual case withintermittent pupillary capture of intraocular lens. DIAGNOSIS: After 5 minutes staying in the dark environment, the pentacam examination revealed a mild nasal pupillary capture of the IOL...

In 2015 Nippita and colleagues developed a novel system to classify women undergoing induction of labour (IOL), which sought to overcome the problems of indication-based classification. We explored the utility and feasibility of this new system at Monash Health in Melbourne. We found overall induction rates of 24.7% compared with the New South Wales rates of 25.4% reported by Nippita et al. The classification system was easy to apply because it uses routinely and accurately collected data. There was no misinterpretation of the classification groups...

Growth of Salmonella enterica serovar Typhimurium strain 14028 with myo-inositol (MI) is characterized by a bistable phenotype that manifests with an extraordinarily long (34 h) and variable lag phase. When cells were pre-grown in minimal medium with MI, however, the lag phase shortened drastically to eight hours, and to six hours in the absence of the regulator IolR. To unravel the molecular mechanism behind this phenomenon, we investigated this repressor in more detail. Flow cytometry analysis of the iolR promoter at a single cell level demonstrated bistability of its transcriptional activation...
