Late swelling after bilateral breast augmentation.

Late unilateral spontaneous swelling following textured breast augmentation is rare.(1) Pathogenesis most commonly relates to intracapsular haematoma or seroma formation although aetiology often remains unclear. We report an intriguing case of late, spontaneous, sequential, recurrent bilateral seromas following breast augmentation. To our knowledge this is the first description following primary surgery.

The partial excision greenstick (PEG) osteotomy: a novel approach to the correction of clinodactyly in children's fingers.

Closing wedge osteotomy is an accepted technique for correcting bony malalignment. This study reports the results of a novel osteotomy technique used in children's hands. Excision of a partial wedge generates a 'greenstick' type of fracture which can then be reduced and stabilised using only intraosseous wires. Eight consecutive patients who underwent surgery of this type between March 2003 and January 2008 were reviewed retrospectively. Union was obtained in all cases and there was good bone alignment and range of movement. No significant technique-related complications were encountered. This approach is a simple and effective way of correcting malalignment in the small bones of children's hands.

Incidence and clinical management of life-threatening left ventricular assist device failure.

BACKGROUND: Mechanical device failure can be life-threatening and is becoming increasingly important as left ventricular assist devices (LVADs) are being used for longer periods as a bridge to transplantation (period lengthening due to donor shortage) or recovery, or as destination therapy. However, its incidence and clinical management have not been widely studied. METHODS: We investigated the incidence and management of major device failure for a total of 102 Thoratec/TCI HeartMate and Thoratec PVAD devices implanted at our institution since 1995. RESULTS: The cumulative probability of device failure was 6%, 12%, 27% and 64% at 6 months, 1 year, 18 months and 2 years, respectively. Major failure occurred in 8 (7.8%) patients. Four patients presented as emergency cases with vented electric (VE) failure, and 3, with failure due to a seized motor, were supported on the pneumatic driver to explantation, transplantation or device change. Another patient had a ruptured pump diaphragm and was maintained for 12 hours, but died of a Type B aortic dissection. Four patients underwent elective device change, including 2 of a VE pump, 1 with inlet valve regurgitation and fractured power cable at 414 days, and 1 with inlet valve regurgitation at 656 days, all of whom underwent transplantation or explantation. One patient with VE failure was maintained on the pneumatic driver, then underwent Thoratec paracorporeal ventricular assist device (PVAD) implantation and was transplanted. One Thoratec PVAD patient developed LVAD thrombus, underwent pump replacement, and was transplanted. A further patient on the implantable pneumatic (IP) HeartMate developed a pneumoperitoneum due to a leak at the junction of the pneumatic driveline, which was repaired by inserting a new driveline, and underwent heart/kidney transplantation. CONCLUSIONS: Life-threatening mechanical device failure is not uncommon and increases with time, but can be managed successfully in most patients. Improvements in design and manufacture should further enhance outcome with LVADs.

Infection of patients by bloodborne viruses.

BACKGROUND: Despite taking precautions, healthcare workers performing invasive procedures run a small risk of infection by bloodborne viruses. When injury occurs, the viral status of the patient is often unknown and testing requires informed consent, which may be refused. On the other hand, although the chance of transmission of infection from a healthcare worker to a patient is extremely small, such personnel have an obligation of disclosure and, if seropositive, are barred from performing invasive procedures. METHODS: The medical literature on bloodborne virus transmission between carers and patients was reviewed, and the UK Department of Health, General Medical Council and Royal College of Surgeons of England guidelines on the risk management of these infections were read, along with secondary references from all sources. RESULTS AND CONCLUSION: Patients have complete protection of confidentiality and the right to refuse testing, but these rights do not apply to the healthcare worker. When injured in circumstances in which the patient cannot or will not permit testing, carers can only submit to the risks of prophylactic treatment or go into denial. Infection may have devastating professional, personal and financial implications to carers and their dependants. Ways to re-establish a just balance between the legitimate rights of patients and healthcare workers are discussed.

Symptomatic calcific stenosis of a Toronto stentless porcine valve.

We describe the calcific structural failure of a Toronto stentless porcine valve (TSPV) which had been used to replace a calcified bicuspid aortic valve in a 46-year-old man. Against expectations, left ventricular hypertrophy persisted and the transvalvular pressure gradient rose to 125 mmHg by 6 years with the patient becoming symptomatic and requiring redo surgery. On removal the TSPV showed atypical calcification of the leaflet hinges and wall. To our knowledge this is the first case reported and it may have implications for long term durability and future surgery using this prosthesis.
