Estimating the health care costs of non-melanoma skin cancer in Saskatchewan using physician billing data.

Introduction: Given the high occurrence and morbidity of non-melanoma skin cancer (nmsc), its economic burden on the Canadian health care system is a cause for concern. Despite that relevance, few studies have used patient-level data to calculate the cost of nmsc. The objective of the present study was to use physician billing data to describe the health care costs and service utilization associated with nmsc in Saskatchewan. Methods: The Saskatchewan Cancer Agency's cancer registry was used to identify patients diagnosed with nmsc between 2004 and 2008. Treatment services and costs were based on physician billing claims, which detail physician services performed in an outpatient setting. Total and annual outpatient costs for nmsc and mean outpatient cost per person were calculated by skin cell type, lesion site, and geographic location. Service utilization and costs by physician specialty were also explored. Results: Total outpatient costs grew 12.08% annually, to $845,954.98 in 2008 from $527,458.76 in 2004. The mean outpatient cost per person was estimated at $397.86. Differences in the cost-per-person estimates were observed when results were stratified by skin cell type ($403.41 for basal cell carcinoma vs. $377.85 for squamous cell carcinoma), lesion site ($425.27 for the face vs. $317.80 for an upper limb), and geographic location ($415.07 urban vs. $363.48 rural). Investigation of service utilization found that 92.14% of treatment was delivered by general practice and plastic surgery/otolaryngology physicians; dermatology delivered only 6.33% of services. Conclusions: Our results underestimate the direct costs of nmsc because inpatient services and non-physician costs were not included in the calculations. The present research represents a first step in understanding the cost burden of nmsc in Saskatchewan.

A simple laboratory algorithm for diagnosis of melioidosis in resource-constrained areas: a study from north-central Vietnam.

OBJECTIVES: Melioidosis may be endemic in many tropical developing countries, but diagnosis of the disease is currently unreliable in resource-limited areas. We aimed to validate a simple and cheap laboratory algorithm for the identification of Burkholderia pseudomallei from clinical specimens in parts of Vietnam where the disease has not previously been reported. METHODS: In June 2015, we conducted training courses at five general hospitals in north-central provinces in order to raise awareness of the disease and to introduce a simple and cheap laboratory identification algorithm for B. pseudomallei including the three-antibiotic disc test. RESULTS: Until the end of the year (7 months later), 94 suspected B. pseudomallei strains resistant to gentamicin and colistin but sensitive to amoxicillin/clavulanic acid were detected in clinical specimens from 70 patients. All strains were further confirmed as B. pseudomallei by using a specific TTSS1 real-time PCR assay and recA sequencing analysis. Among positive blood cultures, positive rates with B. pseudomallei ranged from 3.4% (5/147) to 10.2% (32/312) in the various clinics. A total of 82.8% (58/70) patients were bacteraemic, with a mortality of 50% (18/36) among patients with known outcome. No death occurred in nonbacteraemic patients. CONCLUSIONS: Our results demonstrate that the introduction of a simple and easy-to-perform laboratory algorithm for the identification of B. pseudomallei from clinical samples, together with clinical awareness raising, can lead to the diagnosis of a significant number of melioidosis cases in resource-limited clinical laboratories which previously did not identify the pathogen.

Successful separation of ischiopagus tripus conjoined twins with one twin suffering from brain damage.

To our knowledge, until 1988, the year we performed our operation, only six other cases of ischiopagus tripus conjoined twins had been separated in the world. In our case, operated on in October 1988, one twin remained in a vegetative state after an episode of acute and dramatic encephalitis. However, the separation was successfully performed and now, 3 years after the operation, the two continue to live. The particularities of this case and the factors that made the separation successful are reported.
