RESUMEN
BACKGROUND Facet joint septic arthritis (SAFJ) is a rare clinical entity that is extremely challenging to diagnose, often presenting unilaterally and with nonspecific clinical symptoms. However, SAFJ has significant morbidity and mortality, especially with delayed diagnosis. It becomes all the more important for the clinician to recognize that SAFJ can present bilaterally and be associated with direct inoculation, such as in acupuncture. CASE REPORT A 53-year-old woman with chronic alcoholism and well-controlled type 2 diabetes mellitus was initially admitted for progressively worsening atraumatic lower back pain. Initial non-contrast magnetic resonance imaging (MRI) of the lumbar spine revealed bilateral L4-L5 and L5-S1 nonspecific facet joint effusions. Clinical examination was unremarkable. Biochemically, the patient had mildly elevated inflammatory markers. She was treated conservatively with close outpatient follow-up. However, her back pain progressively worsened, with new-onset lower limb weakness and numbness. Repeat MRI showed L4-L5 bilateral facet joint fluid collection with adjacent bony destruction, as well as posterior paraspinal and epidural fluid collections compatible with L4-L5 bilateral SAFJ with paraspinal and epidural abscesses. Urgent surgical drainage and bilateral lateral facet decompression was performed. Intraoperative cultures revealed methicillin-sensitive Staphylococcus aureus as the causative organism. Postoperatively, 6 weeks of intravenous and oral antibiotics were given with good recovery. CONCLUSIONS We describe a case of bilateral SAFJ following acupuncture that was initially missed. With the increasing prevalence of acupuncture treatment for lower back pain, bilateral SAFJ should be a diagnostic consideration. Detailed clinical history is key; this, as well as a high index of suspicion, early evaluation and treatment, are essential to obtain a favorable outcome.

RESUMEN
Postoperative X-rays are a key part of management of orthopaedic patients. These X-rays serve to check stability of orthopaedic fixation as well as to ensure that there are no peri-implant fractures and periprosthetic fractures following surgical fixation of fractures and arthroplasty procedures, respectively. Timely accurate interpretation of postoperative X-rays are crucial in guiding weight-bearing status as well as rehabilitation. Therefore, delays in X-ray acquisition may impact initiation of postoperative rehabilitation and overall length of stay negatively. The aim of this project is to optimise acquisition of postoperative X-rays in patients undergoing implant surgery and as a result increase efficiency of deployed healthcare staff. A multidisciplinary team was formed to study the efficacy of a new workflow for patients to undergo X-rays immediately after surgery while en-route to the ward. Pretrial and in-trial delays in acquiring X-rays and total man-hours spent on transport were recorded. These processes were refined and integrated to optimise the new workflow. Compared with the old workflow, delays in obtaining X-rays were significantly reduced from the longest of 20 hours and 40 min to no delays at all. Overall man-hours spent on transport of these patients were reduced by a mean of 12 and 16 min for nurses and porters, respectively. The trial workflow has since been adopted successfully by our institution and since inception has become standard practice, allowing timely review of postoperative X-rays. This has led to increased workforce efficiency as well as timely rehabilitation and discharge of patients.

BACKGROUND: Computed tomography (CT) is associated with a risk of cancer development. Strategies to reduce radiation doses vary between centers. We compared radiation doses of CT brain studies between pediatric and general emergency departments (EDs), and determine the proportion studies performed within the reference levels recommended by the International Commission on Radiological Protection (ICRP). METHODS: A retrospective review was carried out in a healthcare network consisting of one pediatric ED and three general hospital EDs. Pediatric patients less than 16 years old with CT brain studies performed between 1 January 2015 and 31 December 2018 were included. Information on demographic, diagnosis, volume-averaged computed-tomography dose index and dose length product (DLP) were collected. Effective dose was then calculated from DLP using conversion factors, termed k-coefficients which were derived using a 16 cm head CT dose phantom. RESULTS: Four hundred and seventy-nine CT brain studies were performed - 379 (79.1%) at the pediatric ED. Seizure (149, 31.1%), head injury (147, 30.7%) and altered mental status (44, 9.2%) were the top three ED diagnoses. The median effective dose estimates were higher in general than pediatric EDs, particularly for those aged > 3 to ≤6 years old [1.57 mSv (IQR 1.42-1.79) versus 1.93 mSv (IQR 1.51-2.28), p = 0.047], > 6 to ≤10 years old [1.43 mSv (IQR 1.27-1.67) versus 1.94 mSv (IQR 1.61-2.59), p = 0.002) and > 10 years old (1.68 mSv (IQR 1.32-1.72) versus 2.03 mSv (IQR 1.58-2.88), p < 0.001). Overall, 233 (48.6%) and 13 (2.7%) studies were within the reference levels recommended by ICRP 60 and 103 respectively. CONCLUSIONS: Radiation doses for CT brain studies were significantly higher at general EDs and less than half of the studies were within the reference levels recommended by ICRP. The development of diagnostic reference levels (DRLs) as a benchmark and clinical justification for performing CT studies can help reduce the radiation risks in the pediatric population.

A 46-year-old man presented with a six-month history of lumps in the sole of his left foot. Physical examination revealed two nodules, one tender and one firm, at the plantar left foot with no overlying skin changes. Although the initial radiographs were normal, magnetic resonance imaging of the left foot demonstrated two nodules along the medial band of the plantar fascia, characteristic of plantar fibromas. The patient opted for surgical excision. There was no further recurrence of symptoms after surgery. We describe the clinical and radiological features of plantar fibromatosis and briefly discuss other causes of lumps and pain in the sole of the foot.

From the rise of restorative justice to evidence-based approaches to reducing recidivism, the intellectual landscape of criminal justice has seen considerable change in recent decades. The result is that an increasing number of countries have tackled the task of shifting preexisting political institutions to confirm with these new understandings. This is, of course, no easy feat. A great number of challenges confront willing policymakers, a reality that often puts philosophy at loggerheads with practicality. Moreover, the political process of change is subject to the influence of cultural and institutional norms. In this paper, we look at one particular case study - that of Malaysia's juvenile justice system - to understand the challenges faced in changing criminal justice policy. We identify three primary categories of challenges and elucidate their shape and impact through the Malaysian example. We also briefly analyze potential opportunities to mitigate and overcome these challenges. Furthermore, we also conclude with several implications for future research that we deem are important to be taken place. In sum, we argue that criminal justice reform must be undertaken with an eye toward important societal and institutional norms, each requiring thoughtful analysis of complex local cases.

The persistent primitive trigeminal artery is the most common persistent carotid-vertebrobasilar anastomosis. Patients are usually asymptomatic and the persistent primitive trigeminal artery is commonly found incidentally on imaging. Rarely, they may present with symptoms of neurovascular conflict or cranial nerve compression syndromes as the artery may be intimately related to the cranial nerves. The basilar artery is often hypoplastic in this condition and blood supply to the posterior circulation is predominantly via the persistent primitive trigeminal artery. Recognizing the persistent primitive trigeminal artery is imperative as disease of the artery may result in ischemia of the posterior circulation. To date, there is no clear association between this artery and cerebral aneurysms. We present a rare case of a patient with a persistent primitive trigeminal artery and a concomitant cavernous carotid aneurysm together with a literature review.

This study aims to explore the potential use of ultrasound in locating the second posterior sacral foramen acupuncture point, quantifying depth of insertion and describing surrounding anatomical structures. We performed acupuncture needle insertion on a study team member. There were four steps in our experiment. First, the acupuncturist located the acupuncture point by palpation. Second, we used an ultrasound machine to visualize the structures surrounding the location of the acupuncture point and measure the depth required for needle insertion. Third, the acupuncturist inserted the acupuncture needle into the acupuncture point at an angle of 30°. Fourth, we performed another ultrasound scan to ensure that the needle was in the desired location. Results suggested that ultrasound could be used to locate the acupuncture point and estimate the depth of needle insertion. The needle was inserted to a depth of 4.0 cm to reach the surface of the sacral foramen. Based on Pythagoras theorem, taking a needle insertion angle of 30° and a needle insertion depth of 4.0 cm, the estimated perpendicular depth is 1.8 cm. An ultrasound scan corroborated the depth of 1.85 cm. The use of an ultrasound-guided technique for needle insertion in acupuncture practice could help standardize the treatment. Clinicians and students would be able to visualize and measure the depth of the sacral foramen acupuncture point, to guide the depth of needle insertion. This methodological guide could also be used to create a standard treatment protocol for research. A similar mathematical guide could also be created for other acupuncture points in future.

A 30-year-old woman presented with a six-month history of left posterior heel pain. Physical examination revealed a tender, inflamed and indurated posterior heel with a visible bony prominence of the posterosuperior aspect of the calcaneus. Lateral ankle radiography showed a prominent left posterosuperior calcaneal tuberosity and thickening of the distal Achilles tendon outline. Magnetic resonance imaging demonstrated high-signal inflammatory fluid in the retrocalcaneal bursa, increased signal intensity and thickening of the Achilles tendon, and prominence of the posterior calcaneus tuberosity with reactive marrow oedema. The findings are consistent with Haglund's deformity. The patient underwent hind foot surgery after failing a six-month course of conservative therapy. There was no further recurrence of symptoms after surgery. The clinical and radiological features of Haglund's deformity are described, including a short discussion of other causes of hind foot pain.
