RESUMEN

BACKGROUND: Hepatitis C virus (HCV) infection is a major global public health problem. In the Republic of Cyprus, the estimated prevalence of chronic hepatitis C (CHC) among the general population is 0.6%, while the CHC prevalence among people who inject drugs (PWID) is estimated at 46%. Direct-acting antivirals that can eliminate HCV are not yet widely available in the Republic of Cyprus. However, when direct-acting antivirals become available, a long-term strategic plan to guide elimination efforts will be needed to maximize the effect of treatment. AIM: To determine the programmatic targets to eliminate HCV in the Republic of Cyprus. METHODS: A dynamic, stochastic, individual-based model of HCV transmission, disease progression, and cascade of care was calibrated to data from Cyprus. The model stratifies the population into the infected general population and the PWID population. A variety of test, prevention, and treatment strategies concerning the general population, PWID, or both were examined. The time horizon of the analysis was until 2034. RESULTS: Under the status quo scenario, the model predicted that 75 (95% confidence interval (CI): 60, 91) and 575 (95%CI: 535, 615) liver-related deaths and new infections would occur by 2034, respectively. Launching an expanded treatment program, without screening interventions, would cause modest outcomes regarding CHC prevalence (16.6% reduction in 2034 compared to 2020) and liver-related deaths (10 deaths would be prevented compared to the status quo scenario by 2034). Implementing a test and treat strategy among the general population but without any intervention in the PWID population would suffice to meet the mortality target but not the incidence target. To achieve HCV elimination in Cyprus, 3080 (95%CI: 3000, 3200) HCV patients need to be diagnosed and treated by 2034 (2680 from the general population and 400 from PWID), and harm reduction coverage among PWID should be increased by 3% per year (from 25% in 2020 to 67% in 2034). CONCLUSION: Elimination of HCV is a demanding public health strategy, which requires significant interventions both among the general population and high-risk groups.

RESUMEN

BACKGROUND: In asymptomatic patients with penetrating thoracic trauma and a normal initial chest x-ray, successive prospective trials have decreased the minimum observation period required for exclusion of significant injury from 6 to 3 h. Despite the quality of these studies, this interval remains arbitrary and the true requisite observation time for safe discharge remains unknown. The current study evaluates the ability of "early" repeat chest x-ray, at intervals approaching 1 h, to exclude clinically significant injury. METHODS: Eighty-eight, asymptomatic patients with penetrating chest trauma and normal initial chest radiographs were prospectively enrolled in this study. All patients received an "early" follow-up chest x-ray, at a median interval of 1 h and 34 min (interquartile range: 1 h 35 min to 2 h 22 min), and a second repeat x-ray at a "delayed" interval no earlier than 3 h postadmission. Radiographic abnormalities in clinically stable patients were followed with serial examination and repeat imaging for a minimum of 6 h. All patients received both "early" and "delayed" repeat CXRs with no patient discharged before full assessment. RESULTS: One of the 88 patients with initially normal chest x-ray underwent tube thoracostomy at the discretion of the attending surgeon before any repeat imaging. Of the remaining patients, 4 of 87 (4.6 %) demonstrated radiographic abnormalities on "early" repeat imaging. Two patients had pneumothoraces, successfully managed without intervention; the remaining two demonstrated evidence of hemothorax, subsequently undergoing tube thoracostomy. Two more patients (2.3 %) developed pneumothoraces on "delayed" imaging, both successfully observed without intervention. CONCLUSIONS: In asymptomatic patients with penetrating thoracic trauma and normal initial chest radiographs, "early" repeat chest x-ray, at intervals approaching 1 h, appears sufficient to exclude clinically significant pathology and to allow safe patient discharge.

RESUMEN

Laparoscopic adjustable gastric banding is a common and effective minimally invasive procedure in the treatment of morbid obesity. Common complications of the procedure include productive burping, ulceration, gastritis, erosion, slippage, problems with the port, bleeding and infection. We report a case of acute appendicitis caused by gastric banding in a female patient. Gastric band encircled the appendix causing lumen obstruction and infection. The patient developed symptoms of topical acute peritonitis and an appendisectomy was performed.

RESUMEN

OBJECTIVE: The use of pulmonary artery catheter (PAC) is controversial. The purpose of this study was to document the changing pattern of PAC use and to determine its effect on outcome. METHODS: The use of PAC was analyzed in patients ≥16 years old admitted to the surgical intensive care unit (SICU) over a 9-year period starting in 2000. Patients with SICU length of stay exceeding 30 days were excluded. For the evaluation of PAC's effect on outcome, PAC and no-PAC patients were matched utilizing propensity scores. RESULTS: During the 9-year study period, a total of 5,192 trauma patients were admitted to the SICU. Of these, 426 (8.2%) were <16 years old, and 174 (3.4%) had a SICU length of stay that exceeded 30 days. For the remaining 4,592 patients, the mean ± SD age was 39.5 ± 18.8 years, and the mean ISS was 19.9 ± 12.4. PAC was utilized in 19.5% (n = 896) of all the patients admitted to the SICU. The trend for PAC use decreased significantly over the years (P value for trend <0.001), from 38.6% in the year 2000 to 4.2% in the year 2008. This decrease was noted in all age and injury severity groups of patients. The overall mortality, however, remained at the same levels (P value for trend = 0.111). Patients managed with a PAC were significantly older, more severely injured, more frequently injured by a blunt mechanism, and were admitted more often in a hypotensive or comatose status. In the early part of the study, the PAC was utilized on the first day and for 4.1 days on average. In the later part of the study, however, the PAC was used on the second day and for a shorter period of time (3 days on average, P < 0.001). In the matched study population, patients in the PAC group had almost twofold higher odds for death, when compared to the no-PAC group [34.2% vs. 22.5%, Odds Ratio (95% CI): 1.78 (1.42, 2.26), P < 0.001]. Patients younger than 50 years of age who had an ISS ≥16 had worse outcome when managed with a PAC, whereas patients aged 30-69 years with an ISS <16 had a higher survival. The overall complication rate was fivefold higher in patients receiving a PAC [46.3% vs. 14.2%, Odds Ratio (95% CI): 5.22 (4.04, 6.74), P < 0.001]. CONCLUSION: The use of PAC has decreased almost 10-fold over the last decade at our institution. The PAC is being used later during the ICU course and for a shorter period of time. In a matched population, the use of PAC is associated with a significantly higher mortality and complication rate, but the reason for this association remains uncertain. The use of PAC is invasive and is associated with known complications and financial costs. While the use of PAC maybe useful in a select population, routine and widespread use of the PAC should be avoided.

RESUMEN

OBJECTIVE: The objective of this study was to identify the incidence and patterns of thoracic aortic injuries in a series of blunt traumatic deaths and describe their associated injuries. METHODS: All autopsies performed by the Los Angeles County Department of Coroner for blunt traumatic deaths in 2005 were retrospectively reviewed. Patients who had a traumatic thoracic aortic (TTA) injury were compared with the victims who did not have this injury for differences in baseline characteristics and patterns of associated injuries. RESULTS: During the study period, 304 (35%) of 881 fatal victims of blunt trauma received by the Los Angeles County Department of Coroner underwent a full autopsy and were included in the analysis. The patients were on average aged 43 years±21 years, 71% were men, and 39% had a positive blood alcohol screen. Motor vehicle collision was the most common mechanism of injury (50%), followed by pedestrian struck by auto (37%). A TTA injury was identified in 102 (34%) of the victims. The most common site of TTA injury was the isthmus and descending thoracic aorta, occurring in 67 fatalities (66% of the patients with TTA injuries). Patients with TTA injuries were significantly more likely to have other associated injuries: cardiac injury (44% vs. 25%, p=0.001), hemothorax (86% vs. 56%, p<0.001), rib fractures (86% vs. 72%, p=0.006), and intra-abdominal injury (74% vs. 49%, p<0.001) compared with patients without TTA injury. Patients with a TTA injury were significantly more likely to die at the scene (80% vs. 63%, p=0.002). CONCLUSION: Thoracic aortic injuries occurred in fully one third of blunt traumatic fatalities, with the majority of deaths occurring at the scene. The risk for associated thoracic and intra-abdominal injuries is significantly increased in patients with thoracic aortic injuries.

RESUMEN

BACKGROUND: Laparoscopic cholecystectomy (LC) is the gold standard for the surgical treatment of cholelithiasis. However, the use of drainage after elective LC in literature remains controversial. METHODS: A randomized study was performed in Larnaka General Hospital. The purpose of the study was to evaluate drainage of the gallbladder bed after elective LC. One hundred sixteen patients were randomly allocated in two groups, sustained an uneventful LC, and were included in the study after an informed consent was obtained. Sixty-three patients were included in drainage group (YD) and 53 patients in nondrainage group (ND). Drain tubes, made of polyethylene, were placed at the end of the procedure in the patients of YD group. Postoperative pain was assessed using two scales: a 10-point visual analog scale and a 5-point verbal response scale. The two groups were evaluated and compared regarding postoperative pain, the time needed for surgery, length of postoperative hospital stay, the postoperative collection of fluid in the subhepatic space, and the incidence of postoperative complications. Chi-square and t-tests were used to evaluate the data, and statistical significance was established at P < .05. RESULTS: The mean operative time in YD patients was 6.9 minutes longer compared with ND patients (P = .056). The postoperative pain was higher in the YD group by more than one point on the average in the visual analog scale both at 6 and 24 hours (P = .01 and <.001, respectively). When measured with the verbal response scale, the difference in the reported pain was very significant at 24 hours (mean level for YD 1.24 and for ND 0.75). The proportion of patients staying in hospital for >2 days was higher in the YD group: 28.6% of the patients versus 13.2% in the ND group (P = .05). Subhepatic fluid was more often observed in the YD group (47% versus 34% in the ND), but the difference was not statistically significant. There was no statistical difference in the rate of wound infections, shoulder pain, nausea, vomiting, and respiratory infections between the two groups. CONCLUSIONS: Our results indicate that routine drainage of gallbladder bed after elective LC may not be justified. Drainage causes more postoperative pain, prolongs the operative time and hospital stay, increases the occurrence of fluid in the subhepatic space, and does not protect from other complications.

RESUMEN

OBJECTIVE: The objective of this study was to analyze autopsy findings after blunt traumatic deaths to identify the incidence of cardiac injuries and describe the patterns of associated injuries. METHODS: All autopsies performed by the Los Angeles County Forensic Medicine Division for blunt traumatic deaths in 2005 were retrospectively reviewed. Only cases that underwent a full autopsy including internal examination were included in the analysis. The study population was divided into two groups according to the presence or absence of a cardiac injury and compared for differences in baseline characteristics and types of associated injuries. RESULTS: Of the 881 fatal victims of blunt trauma received by the Los Angeles County Forensic Medicine Division, 304 (35%) underwent a full autopsy with internal examination and were included in the analysis. The mean age was 43 years +/- 21 years, patients were more often men (71%) and were intoxicated in 39% of the cases. The most common mechanism was motor vehicle collision (50%), followed by pedestrian struck by auto (37%), and 32% had a cardiac injury. Death at the scene was significantly more common in patients with a cardiac injury (78% vs. 65%, p = 0.02). The right chambers were the most frequently injured (30%, right atrium; 27%, right ventricle). Among the 96 patients with cardiac injuries, 64% had transmural rupture. Multiple chambers were ruptured in 26%, the right atrium in 25%, and the right ventricle in 20% of these patients. Patients with cardiac injuries were significantly more likely to have other associated injuries: thoracic aorta (47% vs. 27%, p = 0.001), hemothorax (81% vs. 59%, p < 0.001), rib fractures (91% vs. 71%, p < 0.001), sternum fracture (32% vs. 13%, p < 0.001), and intra-abdominal injury (77% vs. 48%, p < 0.001) compared with patients without cardiac injury. Of the 96 patients with a cardiac injury, 78% died at the scene of the crash and 22% died en route or at the hospital. CONCLUSION: Cardiac injury is a common autopsy finding after blunt traumatic fatalities, with the majority of deaths occurring at the scene. Patients with cardiac injuries are at significantly increased risk for associated thoracic and intra-abdominal injuries.

RESUMEN

BACKGROUND: The objective of this study was to evaluate the risk of mortality and complications associated with cirrhosis in trauma patients. METHODS: This is an IRB-approved retrospective trauma registry study of patients admitted to an academic level 1 trauma center from 1997 to 2006. The following parameters were abstracted for analysis: age, gender, mechanism of injury, Abbreviated Injury Score, Injury Severity Score, Glasgow Coma Scale, mortality, and complications (ARDS, acute renal failure, pneumonia, intra-abdominal abscess, trauma-associated coagulopathy). Multivariable analysis was utilized to compare the mortality and complication rates between cirrhotic and noncirrhotic trauma patients. The subgroup of patients who underwent laparotomy was also analyzed. RESULTS: During the 10-year study period there were 36,038 trauma registry patients, of which 468 (1.3%) had a diagnosis of cirrhosis. The mortality in the cirrhotic group was 12% vs. 6% in the noncirrhotic group [adjusted odds ratio = 5.65 (95% CI = 3.72 - 8.41, p < 0.0001)]. ARDS, trauma-associated coagulopathy, and septic complications were significantly more common in the cirrhotic group. The overall severe complication rate in the two groups was 10 and 4%, respectively [adjusted odds ratio = 2.05 (95% CI = 1.45 - 2.84, p < 0.0001)]. For the subgroup of patients who underwent emergent abdominal exploration, the mortality rate increased to 40% compared with that of noncirrhotics at 15% [adjusted odds ratio = 4.35 (95% CI = 2.00 - 9.18, p = 0.0002)]. CONCLUSION: Cirrhosis is an independent risk factor for increased mortality and higher complication rate following trauma. Injured patients who undergo laparotomy are significantly more likely to die than noncirrhotic patients. Injured patients with cirrhosis warrant aggressive monitoring and treatment.

RESUMEN

BACKGROUND: The objective of this study was to describe the management of the Jehovah's Witness (JW) in an intensely active level I trauma center and review the modern therapeutic options available for the trauma care of these patients. STUDY DESIGN: A retrospective review of injured JWs admitted to a busy trauma center over a 13-year period was conducted. RESULTS: Over the study period, 143 JWs were identified. Among these, 15.4% (22/143) overall and 32.3% (10/31) requiring surgical intensive care unit (SICU) admission accepted transfusion. Overall, 56.6% of JWs (81/143) required operation and 21.7% (31/143) were admitted to the SICU with a complication rate of 4.2% (6/143) and a mortality of 1.4% (2/143). One patient of the 31 patients that were admitted to the SICU received 10 ml of blood with subsequent discontinuation of the transfusion and was excluded from analysis. Of the 30 JWs admitted to the SICU, 20 (66.7%) did not receive transfusion and demonstrated mean admission and nadir hemoglobin (Hb) levels of 12.7 (±2.5) and 9.1 (±3.0) mg/dl, respectively. Ten patients accepted transfusion. This group had longer mean SICU stays (23.3 vs. 5.5 days) but similar mortality (10%, 1/10 vs. 5%, 1/20) compared to non-transfused counterparts. Only one complication (1/20, 5%) was observed in the JWs who were not transfused, compared to a 40% (4/10) complication rate in those accepting transfusion. CONCLUSION: Although our experience was limited, we found no significant difference in the mortality or morbidity between JW patients who received or abstained from transfusion following major trauma. We should keep in mind that the population was small, in order to extract safe conclusions regarding whether we should transfuse or not transfuse trauma patients. We can, however, see interesting insights on the value of trauma resuscitation.

RESUMEN

A 52-year-old Cypriot woman was admitted to the surgical department of Larnaca General Hospital complaining of diarrhea and pain in the right upper and lower quadrants, which was reproduced by clinical examination. A palpable mass was also felt in the region. The white blood cell count was 8420/mul: 73.9% neutrophils, 13.3% lymphocytes and 6.9% eosinophils. Erythrocyte sedimentation rate was 80 mm/h. Parasitic examination of the stools was negative. A colonoscopy located a small mass near the ileoceacal valvule, which was sent for a biopsy. A barium enema and computed tomography scan revealed the same lesion to have expanded into the ascending colon. Despite negative biopsy reports, other findings suggestive of colon cancer prompted us to perform a right hemicolectomy and ileotransverse end to side anastomosis. The mass was found to be expanding into the surrounding fat tissue and into the regional lymph notes. Surprisingly, histological examination of the mass revealed visceral larva migrans, owing to ascaris Toxocara canis or Toxocara cati.
