ABSTRACT
BACKGROUND: Given the improved survival of patients requiring decompressive craniectomies, the frequency of subsequent cranioplasties are on the rise. The most feared complication of autologous cranioplasty is infection and one method for reducing the rate of infection, is to store the bone flaps at subnormal temperatures. However, to date there is no defined temperature for flap storage and temperature ranges from - 18 to - 83°C have been described in literature. Considering our limited resources it has been the practice at our center to store bone flaps at - 26°C. In this study, we have retrospectively reviewed our practice and have audited this choice of temperature with respect to the frequency of infections. METHODS: A retrospective review was conducted for all cranioplasties performed at our center between January 2001 to March 2011, using autologous bone which was cryopreserved according to institutional protocol. During this period the operative and cryopreservation protocol remained the same. All patient records including charts, notes and laboratory findings were reviewed with a specific focus to identify infections. RESULTS: Of the 88 patients included in the study, only 3 (3.40%) patients were found to show signs of infection. Of these, two patients had superficial surgical site infections which resolved with oral antibiotics (Co-Amoxiclav 1 gm BD for 7 days). However the third patient developed deep surgical site infection requiring re-exploration and washout. All three patients had complete resolution of infection with preservation of autologous bone. CONCLUSION: Despite our method of keeping the bone flap in freezer at - 26°C we have reported an acceptable rate of infection and raised the notion whether there is a justification for sophisticated and costly equipment for bone flap preservation, especially in resource depleted setups.

Chylothorax is a rare clinical condition that can be attributed to a damaged thoracic duct. The condition is suggested by aspiration of milky white fluid from the pleural cavity and is commonly associated with either malignant diseases or trauma (e.g. cardiothoracic surgery). We present the case of a 15-year-old boy with chylothorax, whose effusion was due to constrictive pericarditis. The definitive treatment of chylothorax involves identification and management of the underlying pathology. We suggest that when dealing with cases of chylothorax, constrictive pericarditis should be considered among the causes.

Gastrointestinal helminthiasis in developing countries contributes to malnutrition and anemia. Diagnosis and treatment of helminthiasis, especially with low worm load is an unmet public health need in such settings. The infection may sometimes become manifest when a second pathology leads to purgation of the gastrointestinal tract. Two cases of helminthiasis are presented in which the infections only became amenable to diagnosis due to acute diarrhoea caused by giardiasis and lactulose administration. In the first case, acute giardiasis revealed Ascaris lumbricoides infestation, and in the second case primary helminthiasis (strongyloidiasis) was revealed by lactulose, and also led to Vibrio cholera bacteremia. These cases highlight the need to diagnose helminth infestations especially with low worm burdens by means of public health surveillance programmes.
