Every-two-month injections of the long-acting cabotegravir + rilpivirine were noninferior to once-monthly injections for virologic suppression at 48 weeks in people living with HIV*, according to the ATLAS-2M** study presented at CROI 2020 — thus providing a potential option with more convenient dosing.

The assumption that children are less vulnerable to the coronavirus disease 2019 (COVID-19) compared to adults is not quite true and may even be dangerous, suggests a recent study.

Sustained use of lopinavir-combined regimen appears to confer benefits among patients with the novel coronavirus disease (COVID-19), with improvement possibly indicated by increasing eosinophils, suggests a recent study.

COVID-19 is a novel disease, with no existing immunity. The virus can be transmitted from person to person, quickly and exponentially. Here’s what we can do to slow down the spread, if not contain the outbreak.

Unwrapped hydroxyapatite orbital implant cuts surgical time, avoids complications

23 Sep 2019
The future of eyesight restoration may come from a most unlikely corneal donor – pigs.

A large case series of enucleations has shown a low rate of implant exposure, which indicates that absence of wrapping material around hydroxyapatite orbital implants does not compromise surgical outcomes. It has also reduced surgical time and prevented complications from wrapping materials.

A retrospective review was conducted on consecutive enucleations with primary hydroxyapatite orbital implant insertion performed at the Scottish Ocular Oncology Service between 1990 and 2014. The unwrapped implant was placed in the posterior portion of the socket and recti muscles sutured end-to-end over the implant.

Of the 347 consecutive enucleations, 59.7 percent had an indication of tumour-related pathology and 40.3 percent painful blind eye. Seventy percent received an implant of 22-mm diameter.

Several complications occurred over a mean follow-up of 3.5 years, including postenucleation socket syndrome (11.5 percent), chronic discharge (9.2 percent), chronic pain (4.3 percent), recurrent conjunctival infection (2.3 percent), conjunctival cysts (2 percent), contracted socket (1.4 percent), implant exposure (1.2 percent), haematoma (0.6 percent) and ill-fitting prosthesis (0.6 percent).

Implant exposure (n=4) occurred at an average of 4.5 months after surgery. Management of this complication included temporalis fascia graft (n=1), tarsoconjunctival flap (n=1), implant removal (n=1) and observation (n=1).

Of the patients, 9.8 required further surgery, including lower lid tightening (4.3 percent), ptosis repair (2.3 percent), conjunctival cyst excision (1.2 percent), fornix reconstruction (1.2 percent), graft/flap for exposure (0.6 percent) and implant removal (0.3 percent).

“Posterior implant placement and end-to-end recti suturing contribute to the success of the procedure,” the authors said.
