Medium-term outcomes in single anaesthetic bilateral total knee replacement surgery: a single surgeon series.

Background: The lifetime risk of developing symptomatic knee osteoarthritis (OA) is estimated to be 45%, with up to two thirds of patients presenting with bilateral knee symptoms. Patients presenting with end stage bilateral knee OA may benefit from single anaesthetic bilateral total knee replacement (SABTKR). Our study aim was to compare the outcomes of SABTKR with unilateral total knee arthroplasty (TKA) in a single surgeon series over a 20 year period.

Case series of shrinking hydroxyapatite orbital implants.

Background: An orbital implant is used after enucleation or evisceration surgery to replace the volume lost and to aid in prosthesis fitting and movement. Different materials have been used through the years. The authors noted that with bone-derived hydroxyapatite orbital implants, some patients lose their orbital volume.

Surgical repair of a meningoencephalocoele in a kākāpō ().

Case History: A kākāpō () chick hatched on an off-shore island of New Zealand with a small white mass protruding through the cranial skin of the head. The chick's growth followed a normal pattern for kākāpō but at 3 weeks of age the cranium mass was non-reducible and fixed in place and the chick was removed from the island for diagnostic imaging and hand-rearing.

Clinical Findings And Treatment: A computed tomography (CT) examination revealed a full-thickness circular defect in the central cranium with suspected herniation of brain and dura.

Evaluation of lactulose, lactose, and fructose breath testing in clinical practice: A focus on methane.

Background And Aim: Breath testing (BT) is used to identify carbohydrate malabsorption and small intestine bacterial overgrowth. Measuring methane alongside hydrogen is advocated to reduce false-negative studies, but the variability of methane production is unknown. The aim of this study is to examine the effect of high methane production on hydrogen excretion after ingesting lactulose, fructose, or lactose.

Position Effect on Facial Soft Tissue Depths: A Sonographic Investigation.

The head is positioned erect for an approximation; yet most facial soft tissue depths (FSTD) used are measured from supine subjects. Depth difference might be significant, but there is a paucity of data to verify. This study compared erect and supine values for 17 landmarks from 30 healthy New Zealand (European population affinity) women (18-30 or 40-55 years) in erect then supine positions.

Surgical treatment for lateral epicondylitis: a long-term follow-up of results.

Hypothesis: Since its first description, the pathology, natural history, and treatment of lateral epicondylitis have remained controversial. For patients in who conservative management fails, surgery remains an option. The optimal method of surgery remains debatable and is further confounded by a relative lack of long-term follow-up studies.
