• Most common helminthic infection (worldwide prevalence 25%)
• Usually asymptomatic.
• Possible symptoms are colicky abdominal pain in adults and growth retardation/intussusception/volvulus in children

• X-ray: usually normal but may present as bowel obstruction (partial or complete), or soft tissue masses
• US: hypo echoic curvilinear tubular structures with well-defined echogenic walls and curling movement of the worm during the exam
• CT: long, thin tubular structure coiled within the small bowel, outlined by oral contrast materials

• Second most common carpal bone fracture
• Two main types: dorsal chip fracture and body fracture
• Dorsal chip fracture (like in our case ) believed to be due to forceful impingement of the triquetrum during wrist hyperextension
• Body fracture frequently associated with perilunate dislocation (direct blow)
• Pain and swelling localized at the dorsum of the wrist where triquetrum is located
• Complication: motor branch of ulnar nerve injury

• Chip fracture best seen on lateral radiograph with hand in flexion
• Body fracture best seen on AP and oblique radiographs
• Fractures are possibly underreported. CT can help in suspected cases.

• Ultrasound can be performed to diagnose pneumothorax with high accuracy
• Normal "lung sliding" is seen when pleura moves against the chest wall during respiration. The movement is easily seen on real-time imaging and can be captured on M-mode ultrasound
• M-mode US shows normal lung sliding as a "seashore sign", in which the motion of pleura/lung produces sand-like granular appearance on the image. The non-mobile chest wall shows several uninterrupted band or "sea"
• Some diseases may produce "loss of lung sliding", most notably pneumothorax

• Absence of lung sliding shown on real-time imaging
• On M-mode as "barcode sign" or "stratosphere sign" (see above image labeled "left")
• More specific sign is the "lung point sign"

• Up to 6% of lung cancer have calcification. Therefore, calcium in a nodule does not exclude possibility of lung cancer
• Suspected malignant nodule if calcium is.... eccentric, amorphous or it involves only a small portion of the nodule
• Benign: central (>10% of cross-sectional area of nodule), diffuse and laminated calcification
• Nodules that are nonsolid or partly solid are more often malignant

The Early Bird rate expires on 31 January 2012. 

Do not miss your last chance to enjoy the early bird rate for the inaugural Society for Emergency Medicine in Singapore Annual Scientific Conference (SEMS ASC). Register by 31 January 2012 for more savings!

Themed "Modern Pedagogy in Emergency Medicine: Educating Our Next Generation", the conference will be held from 24-26 February 2012 in Singapore at the Suntec Singapore International Convention and Exhibition Centre. It aims to enhance your clinical knowledge and enable you to make informed clinical decisions during critical moments.

Programme Highlights

• Gain valuable insights on recent developments in Education in Emergency Medicine, Geriatric Emergency, Emergency Cardiology, and more, delivered by a panel of international and local veteran emergency physicians, specialists and educators.
• Earn up to 8 Continuing Medical Education (CME) credits by attending the Main Conference and additional credits for Pre-conference workshops.
• Expand your knowledge and expertise by engaging with fellow peers and colleagues from the emergency medicine community.
• Participate in the site visit to Khoo Teck Puat Hospital (KTPH)... and more!

Early bird rate expires on 31 January 2012! So register today!

• Sternoclavicular (SC) joint is diarthrodial articulation between axial and appendicular skeleton, which is subject to same disease process that occur in other joints (degenerative arthritis, rheumatoid arthritis, infection and subluxation. Degenerative arthritis is the most common).
• Up to 30% of patients with rheumatoid arthritis have changes in SC joints (a part of polyarticular involvement) but radiographic findings are often unremarkable.

• Synovitis
• Bone marrow edema and enhancement of subcortical bone (after IV contrast)Er
• Erosion and indistinct cortical margins
• Think infection if: unilateral, history of IVDU and immunocompromised states

• Also known as scrotal abscess
• Can be superficial (from infected hair follicles, wound) or intrascrotal
• Causes: epididymitis, TB, instrumentation, neurogenic bladder, chronic catheter indwelling, spread from intraabdominal infection (i.e., appendicitis)
• Intrascrotal abscess requires surgical drainage

• US is the modality of choice
• Complex-appearing fluid around the testicle
• Scrotal skin thickening with hyperemia
• Evidence of causes such as epididymitis or others
• Based on imaging, it is difficult to distinguish pyocele from hematocele

• Renal scar is a common incidental finding during imaging of the GU tract
• It can occur both with and without episodes of infundibular obstruction
• Reflux is considered a major contributor in development of non-obstructive scarring, particularly in children with vesicoureteric reflux (VUR)
• In adults, renal scarring is more associated with renal stone disease, either with stone or history of stone

• Focal cortical thinning and depression of the cortex, overlying the pyramid on any imaging modalities (IVU, US, CT, MR)
• Hyperechoic band is seen over the parenchymal thinning on US
• Mimic = normal renal lobulation. Lobulation will span the pyramids with echogenic lobular junctions into renal columns

• Long list of differential possibilities: neoplastic vs. non-neoplastic conditions
• Most helpful test = fine needle aspiration biopsy (accuracy 85-90% in experienced cytologist's hands)
• CT/MRI helpful for treatment planning to determine disease extent and whether facial nerve would need to be sacrificed during surgery

• Can be limited by patient's demographic information: age and immune status
• Facial nerve palsy implies malignancy and poor prognosis
• Children: hemangioma, lymphangioma, first branchial cleft cyst, pleomorphic adenoma
• AIDS: benign lymphoepithelial cysts, infection, lymphoma
• Adults: pleomorphic adenoma (>80%), Warthin tumor, malignant tumor (mucoepidermoid, adenoid cystic carcinoma), metastasis, lymphoma
• Other nonneoplastic parotid masses: reactive adenopathy, cystic lymphoid hyperplasia, sarcoidosis

• Lung/pleural disease: Pneumonectomy, lobectomy, pleurisy, subpulmonic effusion
• Diaphragm disease: Phrenic nerve palsy / eventration
• Abdominal disease: Hepatomegaly / hepatic mass / abdominal neoplasm / distended stomach

• First detection of AFP in serum of HCC patients in 1970s
• Currently, it is the only widely used serologic marker for diagnosing HCC. Additional useful markers in use are AFP-L3 and DCP
• Normal range 10-20 ng/mL
• AFP greater than 400 ng/mL generally considered a point of discriminating HCC from other chronic liver disease
• Problem: about 60% of patients with HCC have AFP below 200, up to 20% have normal AFP (AFP-negative HCC; AFP below 20)

• Less likely to be hepatitis B positive
• Tend to have a lower level of ratio of serum glutamic oxaloacetic transaminase (AST)/pyruvic transaminase (ALT)
