RESUMEN
Background Pre-liver transplant (LT) sarcopenia is associated with poor survival. Methods exist for measuring body composition with use of CT scans; however, it is unclear which components best predict post-LT outcomes. Purpose To quantify the association between abdominal CT-based body composition measurements and post-LT mortality in a large North American cohort. Materials and Methods This was a retrospective cohort of adult first-time deceased-donor LT recipients from 2009 to 2018 who underwent pre-LT abdominal CT scans, including at the L3 vertebral level, at Johns Hopkins Hospital. Measurements included sarcopenia (skeletal muscle index [SMI] <50 in men and <39 in women), sarcopenic obesity, myosteatosis (skeletal muscle CT attenuation <41 mean HU for body mass index [BMI] <25 and <33 mean HU for BMI ≥25), visceral adipose tissue (VAT), subcutaneous adipose tissue (SAT), and VAT/SAT ratio. Covariates in the adjusted models were selected with use of least absolute shrinkage and selection operator regression with lambda chosen by means of 10-fold cross-validation. Cox proportional hazards models were used to quantify associations with post-LT mortality. Model discrimination was quantified using the Harrell C-statistic. Results A total of 454 recipients (median age, 57 years [IQR, 50-62 years]; 294 men) were evaluated. In the adjusted model, pre-LT sarcopenia was associated with a higher hazard ratio (HR) of post-LT mortality (HR, 1.6 [95% CI: 1.1, 2.4]; C-statistic, 0.64; P = .02). SMI was significantly negatively associated with survival after adjustment for covariates. There was no evidence that myosteatosis was associated with mortality (HR, 1.3 [95% CI: 0.86, 2.1]; C-statistic, 0.64; P = .21). There was no evidence that BMI (HR, 1.2 [95% CI: 0.95, 1.4]), VAT (HR, 1.0 [95% CI: 0.98, 1.1]), SAT (HR, 1.0 [95% CI: 0.97, 1.0]), and VAT/SAT ratio (HR, 1.1 [95% CI: 0.90, 1.4]) were associated with mortality (P = .15-.77). Conclusions Sarcopenia, as assessed on routine pre-liver transplant (LT) abdominal CT scans, was the only factor significantly associated with post-LT mortality. © RSNA, 2022 See also the editorial by Ruehm in this issue.

PURPOSE: To evaluate whether intraoperative neuromonitoring (IONM), including pre-embolization lidocaine injection challenge ("provocative testing") is associated with reduced risk of irreversible nerve injury during embolization of peripheral arteriovenous malformations (AVMs). MATERIALS AND METHODS: Medical records of patients with peripheral AVMs who underwent embolotherapy with IONM with provocative testing between 2012 and 2021 were reviewed retrospectively. Data collected included patient demographic characteristics, AVM location and size, embolic agent used, IONM signal changes after lidocaine and embolic agent injections, postprocedural adverse events, and clinical outcomes. Decisions regarding whether embolization would proceed at specific locations were based on IONM findings after the lidocaine challenge and as embolization proceeded. RESULTS: A cohort of 17 patients (mean age, 27 years ± 19; 5 women) who underwent 59 image-guided embolization procedures with adequate IONM data was identified. No permanent neurologic deficits occurred. Transient neurologic deficits were observed in 3 patients (4 sessions), comprising skin numbness (2 patients), extremity weakness (1 patient), and extremity weakness and numbness (1 patient). All neurologic deficits resolved by postoperative day 4 without additional treatment. CONCLUSIONS: IONM, including provocative testing, during AVM embolization may minimize potential nerve injury.

BACKGROUND: Regional anesthesia with adductor canal block has become the standard of care for pain management after total knee arthroplasty (TKA). We hypothesized that liposomal bupivacaine (LB) may be noninferior to continuous nerve block with a pain pump in terms of average pain scores, 30- and 90-day readmissions, and emergency department (ED) visits while reducing cost. METHODS: A retrospective chart review was performed on primary TKA patients from 2015 to 2020 by 23 orthopaedic surgeons at a single institution. The inclusion criteria was treatment with LB or a pain pump, and exclusion criteria was receipt of both anesthetics and revision surgery. A total of 2,378 patients met the inclusion criteria with 1,640 patients treated with LB and 738 treated with the pain pump. Demographic differences were not statistically significant. Primary outcomes were average pain scores, 30- and 90-day readmissions, and ED visits. Secondary outcomes were average milligram morphine equivalents per admission, hospital lengths of stay , and costs. RESULTS: There was no significant difference in pain scores on postoperative days 0, 1, 2, or 3 (P = .77, .86, 0.08, and 0.40, respectively), 30- or 90- day readmissions (P = .527 and P = .374), ED visits (P = .129 and P = .108), milligram morphine equivalents utilizations (P = .194), or average hospital LOS (P = .348). We estimated a potential cost savings of $95 per patient and $155,800 over the course of the study. CONCLUSION: LB was found to be noninferior to a pain pump, and the transition to this medication was associated with cost savings.

Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant fibrovascular dysplasia caused by mutations in ENG, ACVRL1, and SMAD4. Increasingly, there has been an appreciation for vascular conditions with phenotypic overlap to HHT but which have distinct clinical manifestations and arise from novel or uncharacterized gene variants. This study reported on a cohort of four unrelated probands who were diagnosed with a rare form of GDF2-related HHT5, for which only five prior cases have been described. Two patients harbored heterozygous missense variants not previously annotated as pathogenic (p.Val403Ile; p.Glu355Gln). Clinically, these patients had features resembling HHT1, including cerebrovascular involvement of their disease (first report documenting cerebral involvement of HHT5), but with earlier onset of epistaxis and a unique anatomic distribution of dermal capillary lesions that involved the upper forelimbs, trunk, and head. The other two patients harbored interstitial deletions larger than five megabases between 10q11.22 and 10q11.23 that included GDF2. To our knowledge, this is the first report detailing large genomic deletions leading to HHT5. These patients also demonstrated mucocutaneous capillary dysplasias, including intranasal vascular lesions complicated by childhood-onset epistasis, with a number of extravascular findings related to their 10q11.21q11.23 deletion. In conclusion, patients with GDF2-related HHT may present with a number of unique characteristics that differ from classically reported features of HHT.

This study aimed to identify the ideal arteriole size to target in bariatric embolization, with the goal of maximizing weight loss efficacy while maintaining patient safety. Although all published clinical trials of bariatric embolization have used embolic microspheres that were at least 300 µm in diameter, optimal weight loss outcomes have been achieved safely in swine using 50-µm embolics. Human fundal remnants from bariatric surgery were compared with swine fundal sections after bariatric embolization with 50-µm embolic microspheres to assess the ideal fundal vessel size for bariatric embolization. In swine, the 50-µm embolic microspheres deposited in the luminal half of the submucosa with a mean arteriole size of 49 µm ± 30. The mean arteriole diameter in the corresponding submucosal layer of the human gastric fundi was 40 µm ± 30. These measurements may inform future clinical trials and direct the development of embolic agents for bariatric embolization.

This study evaluated fundal arteriole angiographic revascularization after embolization with embolic microspheres of 3 different diameters in a swine model (16 swine, 31 arterioles). In the 50-µm group, 7 of 11 (64%) arterioles recanalized completely, 3 of 11 (27%) arterioles recanalized partially, and 1 of 11 (9%) arterioles had collateralization (no recanalization). In the 100- to 300-µm group, 7 of 10 (70%) arterioles recanalized completely and 3 of 10 (30%) arterioles) recanalized partially. In the 300- to 500-µm group, 7 of 10 (70%) arterioles recanalized completely, 1 of 10 (10%) arterioles recanalized partially, and 2 of 10 (20%) arterioles had collateralization. No difference was found between the groups in the degree of recanalization (P = .64). All embolized arterioles exhibited some degree of angiographic revascularization, irrespective of the microsphere size.

PURPOSE: To assess the safety, feasibility, and efficacy of percutaneous thermal ablation (TA) in the treatment of metastatic gynecologic (GYN) tumors. MATERIALS AND METHODS: A study cohort of 42 consecutive women (mean age, 59. years; range, 25-78 years) with metastatic GYN tumors (119 metastatic tumors) treated with radiofrequency (n = 47 tumors), microwave (n = 47 tumors), or cryogenic (n = 30 tumors) ablation from over 2,800 ablations performed from January 2001 to January 2019 was identified. The primary GYN neoplasms consisted of ovarian (27 patients; 77 tumors; mean tumor diameter [MTD], 2.50 cm), uterine (7 patients; 26 tumors; MTD, 1.89 cm), endometrial (5 patients; 10 tumors; MTD, 2.8 cm), vaginal (2 patients; 5 tumors; MTD, 2.40 cm), and cervical (1 patient; 1 tumor; MTD, 1.90 cm) cancers. In order of descending frequency, metastatic tumors treated by TA were located in the liver or liver capsule (74%), lungs (13%), and peritoneal implants (9%). Single tumors were also treated in the kidneys, rectus muscle, perirectal soft tissue (2.5%), and retroperitoneal lymph nodes (1.6%). All efficacy parameters of TA and definitions of major and minor adverse events are categorized by the latest Society of Interventional Radiology reporting standards. RESULTS: The median follow-up of treated patients was 10 months. After the initial ablation, 95.6% of the patients achieved a complete tumor response confirmed by contrast-enhanced magnetic resonance imaging or computed tomography. On surveillance imaging, 8.5% of the ablated tumors developed local progression over a median follow-up period of 4.1 months. Five of 8 tumors with local recurrence underwent repeated treatment over a mean follow-up period of 18 months, and 4 of 5 tumors achieved complete eradication after 1 additional treatment session that resulted in a secondary efficacy of 80%. The overall technique efficacy of TA was 96.2% over a median follow-up period of 10 months. CONCLUSIONS: TA was safe and effective for the local control of metastatic GYN tumors in the lungs, abdomen, and pelvis, with an overall survival rate of 37.5 months and a local progression-free survival rate of 16.5 months, with only 4.8% of treated patients experiencing a major adverse event.

The Society of Interventional Radiology Foundation commissioned a Research Consensus Panel to establish a research agenda on "Obesity Therapeutics" in interventional radiology (IR). The meeting convened a multidisciplinary group of physicians and scientists with expertise in obesity therapeutics. The meeting was intended to review current evidence on obesity therapies, familiarize attendees with the regulatory evaluation process, and identify research deficiencies in IR bariatric interventions, with the goal of prioritizing future high-quality research that would move the field forward. The panelists agreed that a weight loss of >8%-10% from baseline at 6-12 months is a desirable therapeutic endpoint for future IR weight loss therapies. The final consensus on the highest priority research was to design a blinded randomized controlled trial of IR weight loss interventions versus sham control arms, with patients receiving behavioral therapy.

INTRODUCTION: Evaluation of suspected septic arthritis of the native adult knee is a common diagnostic dilemma. Pre-aspirate criteria predictive of septic arthritis do not exist for the adult knee and investigations of aspiration results (cell count, differential, gram stain and crystal analysis) have been limited to univariate analyses. Given numerous clinical variables inform the risk of septic arthritis, multivariable analysis that incorporates all clinically available information is critical to allowing accurate decision-making. METHODS: We retrospectively identified 455 cases of potential septic arthritis of a native adult knee at a tertiary health system from 2012 to 2017, of which 281 underwent aspiration. We recorded demographics, comorbidities, history, exam, laboratory, and radiographic data. Among aspirated cases, we performed univariate analyses of all variables for association with septic arthritis followed by multivariable logistic regression analysis. RESULTS: Septic arthritis was confirmed in 61 of 281 patients who underwent aspiration. Independent associations of risk for septic arthritis included synovial fluid WBC ≥ 30,000 (Odds Ratio 90.8, 95% Confidence Interval 26.6-310.1, p < 0.001), bacteria reported on synovial fluid gram stain (OR 21.5, 95% CI 3.9-119.2, p < 0.001), duration of pain >2 days (OR 6.9, 95% CI. 2.3-20.9, p < 0.001), history of septic arthritis at any joint (OR 5.0, 95% CI 1.1-23.4, p = 0.039), clinical effusion (OR 4.8, 95% CI 1.2-20.0, p = 0.030). Independent associations protective against septic arthritis included presence of synovial fluid crystals (OR 0.1, 95% CI 0.1-0.4, p < 0.001). The multivariable model was highly accurate in discriminating between septic and aseptic cases (AUC = 0.942). A web-based tool was created to aid clinical decision-making. CONCLUSION: When evaluating for septic arthritis of a native adult knee, several independent associations were identified for variables related and unrelated to joint aspiration. The associated multivariable model discriminated very well between patients with and without septic arthritis, outperforming previous univariate assessments. A web-based tool was created that estimates the probability of septic arthritis based on this model. This may aid decision-making in complex clinical scenarios.

PURPOSE: We sought to compare preferences for arthroplasty versus arthrodesis among patients with proximal interphalangeal (PIP) joint osteoarthritis (OA) by quantifying the patient-assigned utility of each operation's attributes. METHODS: We undertook a multistep process to identify relevant surgical attributes, including a literature review, surgeon survey, and pretest patient pilot test to build a set of discrete choice experiments. Patients with PIP joint osteoarthritis were identified using a single university electronic medical record and were recruited via electronic message or postcard. Participants completed a demographic survey and 11 discrete choice experiments designed using Sawtooth Software's Discover tool. Utility and importance scores were generated for each attribute. RESULTS: Pretest analysis identified out-of-pocket cost, joint stiffness, need for future surgery, change in grip strength, and total recovery time as the most important surgical attributes. Initial response rate to the conjoint survey was 75% and survey completion rate was 61%. The study sample was predominantly white (91%) and female (72%), mean age 64.3 years (range, 34-90 years), and mean daily pain score was 4.32 (range, 0-10). Attribute importance scores demonstrated that joint stiffness (32%) and grip strength (29%) were most important to patients. Cost (17%) and need for future surgery (19%) were intermediate patient-preference drivers. Recovery time was the least important attribute (2%). CONCLUSIONS: In aggregate, patients prefer surgical attributes characteristic of arthroplasty (ability to preserve joint motion and grip strength) relative to those associated with arthrodesis (decreased need for reoperation, lower costs, and shorter reoperation times). TYPE OF STUDY/LEVEL OF EVIDENCE: Economic/Decision Analysis III.

PURPOSE: Thumb carpometacarpal (CMC) arthritis contributes considerably to functional disability in the aging adult United States (US) population. Owing to the increasing growth in this segment of our population, its burden on health care resources will increase in the future. Variations exist in the degree of complexity and cost among different surgical treatments. We examined the national trends of the surgical treatment of thumb CMC arthritis and hypothesized that current practice patterns are not supported by evidence favoring the simpler trapeziectomy-only procedure. METHODS: Using a random 5%, nationally representative, sample of Medicare fee-for-service beneficiaries diagnosed with thumb CMC arthritis between 2001 and 2010, we used a multinomial logistic regression model to assess the association between patients' characteristics and the surgical treatment. Furthermore, we used surgeons' unique identifiers to examine how their practice preferences have changed over time. RESULTS: Our findings demonstrated an increasing trend in the utilization of trapeziectomy with ligament reconstruction and tendon interposition (LRTI) from 84% in 2001 to 90% in 2010. Ninety-five percent of surgeons performed only 1 type of surgical procedure, and among those, 93% of surgeons performed only trapeziectomy with LRTI. Compared with 2001, the odds of a patient undergoing thumb CMC arthrodesis or prosthetic arthroplasty slightly increased between 2007 and 2010. CONCLUSIONS: The majority of hand surgeons in the US use trapeziectomy with LRTI as the surgical treatment of choice for thumb CMC arthritis. Although clinical trials from the United Kingdom support the use of the less complex trapeziectomy-only procedure, US surgeons are still reticent to change their practice, which favors LRTI. National comparative studies are still needed to examine the effectiveness of various surgical options for the treatment of thumb CMC joint arthritis. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

PURPOSE: To examine outcomes and complications of the porous polyurethaneurea (Artelon; Small Bone Innovations, Morrisville, PA) spacer compared to traditional surgical treatment of trapeziectomy with ligament reconstruction and tendon interposition (LRTI). METHODS: A retrospective chart review was undertaken of patients with carpometacarpal (CMC) arthritis who had either placement of an Artelon spacer or LRTI. Patients were brought back to clinic for interview and functional testing. Pain was graded using a visual analog scale. Grip and pinch strength, as well as range of motion at the first CMC joint, were measured. Nine-hole peg, Moberg pickup, and Jebson-Taylor tests were performed. Research and Development 36, Michigan Hand Outcomes, and Quick Disabilities of the Arm, Shoulder, and Hand questionnaires were administered. RESULTS: Thirty-eight patients received Artelon implants into the CMC joint, and 6 were lost to follow-up. Twelve of 32 patients (37%) required revision surgery with removal of implant and salvage arthroplasty. Twenty patients with nonrevised Artelon implants were compared with 10 patients who received 13 LRTI procedures. Patients with Artelon had significantly less pain improvement compared to those receiving the LRTI procedure. In addition, satisfaction was significantly decreased. There was no significant difference in any other functional or quality of life measures. CONCLUSIONS: In our practice, use of the Artelon joint spacer resulted in an explantation rate of 37%. Due to these findings, we have abandoned its use for treatment of basilar thumb osteoarthritis. In contrast to previous studies, pain and satisfaction are worse in patients with intact Artelon spacers than those who had received LRTI.

BACKGROUND: Open A1 pulley release for trigger finger has generally been considered a minor procedure with infrequent complications. Most reported complications are minor, including scar pain and tenderness, mild extension lag, and recurrence of triggering. Rates of major complications, such as bowstringing, neurovascular bundle injury, and infection requiring reoperation, are less than 1% to 4%. We aimed to describe the potentially devastating sequelae of these major complications and the subsequent consequences. METHODS: Three patients underwent open trigger finger release, which were all complicated by severe postoperative surgical site infection requiring multiple subsequent procedures. We review our initial management, subsequent reconstructive options, and outcomes with up to 19 years follow-up. RESULTS: All 3 adult patients who underwent open A1 pulley release for trigger finger developed a surgical site infection, leading to flexor tenosynovitis requiring urgent operative debridement and multiple subsequent procedures. Two patients were poorly controlled diabetics, and the third patient was otherwise healthy. Each patient ultimately developed distinct consequences from their postoperative course-finger stiffness and contracture, disabling bowstringing requiring the use of a pulley ring, and flexor tendon rupture requiring staged tendon reconstruction, respectively. All 3 patients at final follow-up had a permanent functional deficit. CONCLUSIONS: Major complications after trigger finger release are infrequent. However, if left untreated, particularly in diabetic patients, there can be disastrous consequences, resulting in permanent loss of function. This case series highlights the importance of accurate diagnosis of postoperative infections and expedient treatment thereafter.
RESUMEN
BACKGROUND: A paucity of literature exists specifically examining self-inflicted (SI) gunshot wounds (GSWs) to the hand and wrist, which impart greater energy and have a higher risk of adverse events than non-self-inflicted (NSI) GSWs. METHODS: We retrospectively reviewed records of patients who presented to our plastic surgery service after sustaining acute GSWs involving the hand and wrist between 2016 and 2018. RESULTS: We identified 60 patients who sustained GSWs involving the hand and wrist; 17 (28%) were SI, and 43 (72%) were NSI. Within the SI group, 100% of patients were Caucasian, with an average age of 54 years. Within the NSI cohort, 77% of patients were Black, 19% were Caucasian, and 4% identified as other. While not statistically significant, we noted a substantial increase in patients requiring operative intervention in the SI cohort (65% SI vs 37% NSI, P = .08). There was a statistically significant increase in patients requiring more than 1 operation in SI patients (24% SI vs 5% NSI, P = .04). Patients who sustained SI injuries were also more likely to present with acute carpal tunnel syndrome requiring urgent surgical release and to develop wound infections (12% vs 0%, P = .08). CONCLUSIONS: Self-inflicted GSWs involving the hand and wrist are associated with greater morbidity than their low-energy NSI counterparts. Individuals presenting with SI GSWs are more likely to be older, to require multiple operations, to develop infections, and to present with acute carpal tunnel syndrome requiring urgent surgical decompression.

BACKGROUND: T1-hyperintensity of the basal ganglia (BG) due to manganese deposition is a known radiologic finding in patients with hereditary hemorrhagic telangiectasia (HHT), but risk factors and associated clinical manifestations are unclear. This study conducted a quantitative analysis of the association of T1-hyperintensity in HHT patients with specific risk factors, signs, and symptoms. METHODS: Patients seen at our center between 2005 and 2020 with a definitive diagnosis of HHT who had an available non-contrast T1-weighted brain MRI were included. Hyperintensity was evaluated using oval regions of interest measurements. The BG: thalamus intensity ratio was used to quantitatively evaluate T1-hyperintensity. Patient laboratory values and clinical findings were collected from electronic medical records. Hyperintensity was analyzed for its association with laboratory values, and clinical findings. Variables were analyzed through regression analysis. RESULTS: A total of 239 patients were included in this study. On 1.5 T scanners, values that were significant on multivariable regression analysis were age (p < .001), hepatic AVMs (p < .001), iron deficiency anemia (p = .0021), and cirrhosis (p = .016). On 3 T scanners, values that were significant on multivariable analysis were hepatic AVMs (p = .0024) and cirrhosis (p = .0056). On 3 T scanners, hyperintensity was significantly associated with tremor (OR = 1.17, p = .033), restless leg syndrome (OR = 1.22, p = .0086), and memory problems (OR = 1.17, p = .046). CONCLUSIONS: BG hyperintensity due to manganese deposition is significantly associated with hepatic risk factors on 1.5 T and 3 T scanners and iron deficiency anemia on 1.5 T scanners. On 3 T scanners, T1-hyperintensity is associated with neuropsychiatric signs and symptoms, such as tremor, restless leg syndrome, and memory problems.

Uterine rupture is an uncommon obstetric emergency that is potentially fatal to the mother and fetus. Spontaneous rupture of the unscarred gravid uterus in postmenopausal women who achieve pregnancy through in vitro fertilization (IVF) has been infrequently described in the literature. We present the case of a 72-year-old postmenopausal woman, gravida 1 para 0, who conceived by donor oocyte IVF in Europe and subsequently suffered uterine rupture at 22 weeks gestation with large hemoperitoneum. The patient underwent emergent laparotomy, with successful repair of the uterine wall defects. Postmenopausal women face an increased risk of spontaneous uterine rupture and life-threatening bleeding, which is likely due to uterine atrophy and limited uterine capacity. Further research is needed to establish age-appropriate guidelines for selecting treatment candidates.
RESUMEN
OBJECTIVES: Delayed symptomatic hyponatremia is a known phenomenon occurring > 3 days after transsphenoidal surgery. This is a significant cause of post-operative emergency room visits and re-admissions. We describe and characterize post-operative hyponatremia in patients undergoing endoscopic transsphenoidal surgery, identify predictive factors, and create a clinical tool for predicting high risk patients. PATIENTS & METHODS: We retrospectively reviewed a series of over 300 consecutive patients undergoing endoscopic transsphenoidal surgery and identified patients with delayed hyponatremia as well as patient, tumor, and surgical characteristics. In addition, we recorded inpatient post-operative sodium and specific gravity values as well as treatment upond discharge. Univariate and multivariate analyses were carried out to identify predictors of delayed hyponatremia and stratify patients into risk groups. RESULTS: We found that 15% of patients developed delayed hyponatremia and that this occurred most commonly on post-operative day 7. This accounted for more than half of re-admissions after this type of surgery. Female patients and patients needing fluid restriction or fludrocortisone upon discharge were more likely to develop delayed hyponatremia. Patients with post-operative diabetes insipidus were less likely to develop delayed hyponatremia. Using ROC analysis we developed a score which reliably could stratify patients at risk for delayed hyponatremia. CONCLUSIONS: We confirm the risk of delayed hyponatremia after transphenoidal surgery and identify factors that are revealed before discharge to identify patients at higher risk of delayed hyponatremia. These data may help identify patients who require treatment upon discharge and short interval follow up to avoid significant costs of re-admission.

BACKGROUND: With international concern over emerging infectious diseases (EID) and bioterrorist attacks, public health is being required to have early outbreak detection systems. A disease surveillance team was organized to establish a hospital emergency department-based syndromic surveillance system (ED-SSS) capable of automatically transmitting patient data electronically from the hospitals responsible for emergency care throughout the country to the Centers for Disease Control in Taiwan (Taiwan-CDC) starting March, 2004. This report describes the challenges and steps involved in developing ED-SSS and the timely information it provides to improve in public health decision-making. METHODS: Between June 2003 and March 2004, after comparing various surveillance systems used around the world and consulting with ED physicians, pediatricians and internal medicine physicians involved in infectious disease control, the Syndromic Surveillance Research Team in Taiwan worked with the Real-time Outbreak and Disease Surveillance (RODS) Laboratory at the University of Pittsburgh to create Taiwan's ED-SSS. The system was evaluated by analyzing daily electronic ED data received in real-time from the 189 hospitals participating in this system between April 1, 2004 and March 31, 2005. RESULTS: Taiwan's ED-SSS identified winter and summer spikes in two syndrome groups: influenza-like illnesses and respiratory syndrome illnesses, while total numbers of ED visits were significantly higher on weekends, national holidays and the days of Chinese lunar new year than weekdays (p < 0.001). It also identified increases in the upper, lower, and total gastrointestinal (GI) syndrome groups starting in November 2004 and two clear spikes in enterovirus-like infections coinciding with the two school semesters. Using ED-SSS for surveillance of influenza-like illnesses and enteroviruses-related infections has improved Taiwan's pandemic flu preparedness and disease control capabilities. CONCLUSION: Taiwan's ED-SSS represents the first nationwide real-time syndromic surveillance system ever established in Asia. The experiences reported herein can encourage other countries to develop their own surveillance systems. The system can be adapted to other cultural and language environments for better global surveillance of infectious diseases and international collaboration.
