Rhabdomyolysis Masquerading as Cauda Equina Syndrome.

Lower back pain is a very common presenting condition, with a large proportion resulting from discogenic causes, especially after strenuous activity. In patients with a history of exertion, lower back pain, and acute urinary retention, the obvious diagnosis to exclude would be cauda equina syndrome. We present a case of a 32-year-old man who presented with lower back pain, bilateral lower limb weakness, and acute urinary retention following a recent episode of heavy lifting. He was subsequently diagnosed with rhabdomyolysis. This case highlights that rarer conditions can masquerade as cauda equina syndrome, and even in seemingly straightforward presentations, alternative diagnoses should also be considered.

Perioperative Challenges in a Septic Shock Patient With Extensive Splanchnic and Extra-Splanchnic Vein Thrombosis Up to the Right Atrium.

Venous thromboembolism (VTE) has a significant disease burden worldwide and comprises deep vein thrombosis (DVT) and pulmonary embolism (PE). DVT most commonly occurs in the lower extremities, very rarely it can present in the splanchnic venous circulation or inferior vena cava or both. We report an unusual presentation of a 68-year-old woman with septic shock secondary to ischemic bowel, complicated by non-tumor related, extensive right hepatic vein thrombosis extending up to the inferior vena cava (IVC) and right atrium. She underwent bowel resection surgery emergently and was started on systemic anticoagulation in the perioperative period after an extensive evaluation and resuscitation. She was managed by a multidisciplinary team during her admission and was discharged after four weeks. This case poses an interesting therapeutic challenge to the team as there is little literature to guide treatment in a critically ill patient with ischemic bowel, septic shock with extensive splanchnic and IVC thrombosis who also had likely pseudo-heparin resistance with artifactual activated partial thromboplastin time (aPTT) values. This case report seeks to share our experience of a multidisciplinary and patient-centric approach in this rare presentation of a disease spectrum.

Quality assurance of LOINC mapping for laboratory tests - a local experience with people, process and technology.

In Hong Kong Hospital Authority (HA), the Electronic Patient Record (ePR) module of Clinical Management System, implemented since 2003, bring together all the information from various clinical module and hospitals into a single corporate wide, longitudinal, integrated record. Nowadays there are billions of laboratory test results stored in the web-based ePR where laboratory results being shared with the HA clinicians for patient care. In order to produce interoperable laboratory data in the ePR, the HA adopts LOINC (Logical Observation Identifiers Names and Codes) as the reference standard for laboratory tests. Every local test codes have been mapped with LOINC code where possible. Thus, the accuracy of LOINC mapping for laboratory tests in the HA is imperative. This paper describes a quality assurance program of LOINC mapping for laboratory tests conducted in 2011/12. With the use of right people, right process and right technology, we reviewed over 28,000 local test codes and there are around 2,400 distinct LOINC concepts mapped and defined in the system.
