RESUMEN

Background: Trauma is an independent risk factor for venous thromboembolism (VTE). Due to contraindications or delay in starting pharmacological prophylaxis among trauma patients with a high risk of bleeding, the inferior vena cava (IVC) filter has been utilized as alternative prevention for pulmonary embolism (PE). Albeit, its clinical efficacy has remained uncertain. Therefore, we performed an updated systematic review and meta-analysis on the effectiveness and safety of prophylactic IVC filters in severely injured patients. Methods: Three databases (MEDLINE, EMBASE, and Cochrane) were searched from August 1, 2012, to October 27, 2021. Independent reviewers performed data extraction and quality assessment. Relative risk (RR) at 95% confidence interval (CI) pooled in a randomized meta-analysis. A parallel clinical practice guideline committee assessed the certainty of evidence using the GRADE approach. The outcomes of interest included VTE, PE, deep venous thrombosis, mortality, and IVC filter complications. Results: We included 10 controlled studies (47 140 patients), of which 3 studies (310 patients) were randomized controlled trials (RCTs) and 7 were observational studies (46 830 patients). IVC filters demonstrated no significant reduction in PE and fatal PE (RR, 0.27; 95% CI, 0.06-1.28 and RR, 0.32; 95% CI, 0.01-7.84, respectively) by pooling RCTs with low certainty. However, it demonstrated a significant reduction in the risk of PE and fatal PE (RR, 0.25; 95% CI, 0.12-0.55 and RR, 0.09; 95% CI, 0.011-0.81, respectively) by pooling observational studies with very low certainty. IVC filter did not improve mortality in both RCTs and observational studies (RR, 1.44; 95% CI, 0.86-2.43 and RR, 0.63; 95% CI, 0.3-1.31, respectively). Conclusion: In trauma patients, moderate risk reduction of PE and fatal PE was demonstrated among observational data but not RCTs. The desirable effect is not robust to outweigh the undesirable effects associated with IVC filter complications. Current evidence suggests against routinely using prophylactic IVC filters.

RESUMEN

BACKGROUND: To develop evidence-based clinical practice guidelines on venous thromboembolism (VTE) prevention in adults with trauma in inpatient settings. METHODS: The Saudi Critical Care Society (SCCS) sponsored guidelines development and included 22 multidisciplinary panel members who completed conflict-of-interest forms. The panel developed and answered structured guidelines questions. For each question, the literature was searched for relevant studies. To summarize treatment effects, meta-analyses were conducted or updated. Quality of evidence was assessed using the Grading Recommendations, Assessment, Development, and Evaluation (GRADE) approach, then the evidence-to-decision (EtD) framework was used to generate recommendations. Recommendations covered the following prioritized domains: timing of pharmacologic VTE prophylaxis initiation in non-operative blunt solid organ injuries; isolated blunt traumatic brain injury (TBI); isolated blunt spine trauma or fracture and/or spinal cord injury (SCI); type and dose of pharmacologic VTE prophylaxis; mechanical VTE prophylaxis; routine duplex ultrasonography (US) surveillance; and inferior vena cava filters (IVCFs). RESULTS: The panel issued 12 clinical practice recommendations-one, a strong recommendation, 10 weak, and one with no recommendation due to insufficient evidence. The panel suggests starting early pharmacologic VTE prophylaxis for non-operative blunt solid organ injuries, isolated blunt TBIs, and SCIs. The panel suggests using low molecular weight heparin (LMWH) over unfractionated heparin (UFH) and suggests either intermediate-high dose LMWH or conventional dosing LMWH. For adults with trauma who are not pharmacologic candidates, the panel strongly recommends using mechanical VTE prophylaxis with intermittent pneumatic compression (IPC). The panel suggests using either combined VTE prophylaxis with mechanical and pharmacologic methods or pharmacologic VTE prophylaxis alone. Additionally, the panel suggests routine bilateral lower extremity US in adults with trauma with elevated risk of VTE who are ineligible for pharmacologic VTE prophylaxis and suggests against the routine placement of prophylactic IVCFs. Because of insufficient evidence, the panel did not issue any recommendation on the use of early pharmacologic VTE prophylaxis in adults with isolated blunt TBI requiring neurosurgical intervention. CONCLUSION: The SCCS guidelines for VTE prevention in adults with trauma were based on the best available evidence and identified areas for further research. The framework may facilitate adaptation of recommendations by national/international guideline policymakers.

RESUMEN

Background: Isolated pulmonary metastasis (IPM) is a rare entity that accounts for 10% of pulmonary metastases seen in colorectal cancer (CRC). This study aims to evaluate the overall 5-year survival of IPM originating from CRC and identify potential prognostic factors affecting the overall survival (OS). Methods: A retrospective cohort study conducted in a tertiary care center. The study included all patients diagnosed with CRC aged 18-75 years who underwent primary tumor resection with curative intent between 2008 and 2015, and developed IPM. Patients with no follow-up and those with extra-pulmonary metastases were excluded. Results: The prevalence of IPM in the overall CRC cases was 4.18% (20/478 patients). The mean age of patients with IPM was 52.7 ± 12.9 years. Ten patients had synchronous IPM (50%), thirteen had unilateral (65%), and eleven underwent metastasectomy (55%). The 5-year OS was 40%, and the mean OS was 3.12 ± 1.85 years. Several factors were found to be associated with a favorable outcome, which include unilateral IPM (3.69 vs. 2.07 years; P = 0.024), metachronous (4.25 vs. 2.14 years; P = 0.017), metastasectomy (4.81 vs. 1.83 years; P = 0.005). In addition, mortality was likely to be decreased by more than 90% after metastasectomy (unadjusted odds ratio = 0.071; 95% confidence interval [CI] = 0.01-0.8; P = 0.032). Conclusions: Forty percent of the included patients survived the 5-year follow-up. Better survival was associated with the metastases being unilateral, metachronous, and metastasectomy. Mortality was lower in patients with pulmonary recurrence after metastasectomy.

RESUMEN

Background: Organophosphate (OP) poisoning is one of the most common etiologies of poisoning in the pediatric age group. Objective: This study aimed to evaluate the demographic characteristics, clinical features, clinical course, and outcomes of children with toxicity from organophosphates admitted to the pediatric intensive care unit. Methods: A retrospective review of hospital medical records of all children aged 14 years and younger who were admitted to the PICU with a provisional diagnosis of organophosphate poisoning at King Fahad Hospital of the University (KFHU), Alkhobar, Saudi Arabia, between January 1, 2008, and December 31, 2018, was conducted. Patients with incomplete medical record information or with suspicion or evidence of one or more agents other than organophosphate were excluded from the study. Results: Thirty-one patients were enrolled in the study. The median age of the study population was 2 years, and 19 (61%) were males. The majority of patients (68%) had more than one route of organophosphate exposure. Skin exposure was reported in 26 patients (84%). Only three patients (10%) had suicidal organophosphate exposure from organophosphates, while the majority (28 patients; 90%) had accidental poisoning. Bronchorrhea was the most prevalent presenting feature, reported in 28 patients (90%). 17 patients (55%) were treated with intravenous atropine and (45%) were used a combination of pralidoxime with atropine for treatment. Five patients (16%) developed acute respiratory distress syndrome. Twelve patients (39%) needed endotracheal intubation and mechanical ventilation secondary to respiratory failure. Conclusion: The presenting features of organophosphate poisoning differ widely in children. Risk factors for mortality for PICU patients with organophosphate poisoning include delayed hospital arrival by more than 1 hour, inhalational route of exposure, need for mechanical ventilation, and high lactate levels in the first 24 hours post-exposure.

RESUMEN

Acute chest syndrome (ACS) is a common cause of death in sickle cell disease (SCD) patients. Multiple studies investigated the risk factors of developing ACS; however, predictors of recurrent ACS episodes have not been thoroughly investigated. We aim to examine the clinical and laboratory predictors of recurrent ACS in pediatric patients with SCD. A retrospective case-control study included pediatric patients with SCD (˂14 years) admitted with ACS or developed ACS during admission for another indication. Patients were classified into recurrent ACS episodes (≥2 episodes) and a single ACS episode groups. Ninety-one ACS episodes (42 patients) were included, with a mean age at diagnosis of 7.18 ± 3.38 years. Twenty-two (52.4%) patients were male, and twenty-five (59.5%) patients had recurrent ACS. Younger age at first ACS was significantly associated with recurrence (p = 0.003), with an optimal cutoff at 7.5 years (area under the receiver operating characteristic curve [AUROC] = 0.833; p < 0.001). Higher SCD-related hospitalizations were significantly associated with recurrence (p = 0.038). Higher mean values of baseline white blood count (WBC) (p = 0.009), mean corpuscular volume (MCV) (p = 0.011), and reticulocyte (p = 0.036) were significantly associated with recurrence. Contrarily, lower baseline hematocrit values (p = 0.016) were significantly associated with recurrence. The ACS frequencies were significantly lower after hydroxyurea (p = 0.021). The odds of ACS recurrence increased with a positive C-reactive protein (CRP) at admission (p = 0.006). In conclusion, several baseline and admission laboratory data showed significant associations with recurrence. Hydroxyurea therapy demonstrated reduced ACS episodes.

RESUMEN

INTRODUCTION: The most common cause of death among sickle cell disease (SCD) patients is acute chest syndrome (ACS). Since SCD is a common condition in the Eastern province of the Kingdom of Saudi Arabia (KSA), we aimed to provide a detailed description of the clinical characteristics and ACS management. METHODS: We retrospectively studied pediatric (<14 years) patients with SCD diagnosis who were admitted with ACS or developed ACS after admission from January 2002 to December 2020. The absence of chest X-ray or hemoglobin electrophoresis was the reason to exclude patients from the study. The primary objective of the study was to evaluate and report the clinical, laboratory, and management characteristics of ACS. RESULTS: Ninety-one ACS episodes (42 patients) were included, with a mean diagnosis age of 7.18 ± 3.38 years. Twenty-two (52.4%) patients were male. Twenty-five patients had recurrent ACS episodes. The median absolute number of ACS was 3.5 (interquartile range [IQR], 2-9), with maximum ACS episodes of 13/1 year and a minimum of 1 ACS episode per year. At the first ACS episode, the mean age was 6.62 ± 3.38 years, while the overall mean age at ACS episode diagnosis was 7.18 ± 3.38 years. The most common antecedent events were vaso-occlusive crisis (12 episodes, 13.2%) and upper respiratory tract infections (8 episodes, 8.8%). The most frequently encountered presenting symptoms were fever (70.3%) and cough (70.3%). The most common antibiotics used were azithromycin (82.4%) and ceftriaxone (75.8%). Nine patients (9.9%) required pediatric intensive care unit (PICU) admission. Of the 91 ACS episodes, there was no in-hospital mortality. The median hospital and PICU length of stay were 8 days (IQR, 5-10.25) and 4 days (IQR, 3-5.5), respectively. CONCLUSION: This study has reported the most common clinical characteristics and management of ACS among pediatric SCD patients in the Eastern province of KSA.

RESUMEN

BACKGROUND: Early use of high-flow nasal cannula (HFNC) decreases the need for endotracheal intubation (EI) in different respiratory failure causes. While HFNC is used in coronavirus disease 2019 (COVID-19)-related acute hypoxemic respiratory failure (AHRF) under weak recommendations, its efficacy remains to be investigated. OBJECTIVES: The primary objective was to examine HFNC efficacy in preventing EI among COVID-19 patients with AHRF. Secondary objectives were to determine predictors of HFNC success/failure, mortality rate, and length of hospital and intensive care unit (ICU) stay. PATIENTS AND METHODS: This is a prospective cohort study conducted at a single tertiary care centre in Saudi Arabia from April to August 2020. Adult patients admitted to the ICU with AHRF secondary to COVID-19 pneumonia and managed with HFNC were included. We excluded patients who were intubated or managed with non-invasive ventilation before HFNC. RESULTS: Forty-four patients received HFNC for a median duration of 3 days (interquartile range, 1-5 days). The mean age was 57 ± 14 years, and 86% were men. HFNC failure and EI occurred in 29 (66%) patients. Patients in whom HNFC treatment failed had a higher risk of death (52% versus 0%; P = 0.001). After adjusting for confounding factors, a high SOFA score and a low ROX index were significantly associated with HFNC failure (hazard ratio [HR], 1.42; 95% confidence interval [CI], 1.04-1.93; P = 0.025; and HR, 0.61; 95% CI, 0.42-0.88; P = 0.008, respectively). CONCLUSIONS: One-third of hypoxemic COVID-19 patients who received HFNC did not require intubation. High SOFA score and low ROX index were associated with HFNC failure.

RESUMEN

Solid pseudopapillary neoplasms (SPN) of the pancreas are rare neoplasms accounting for 1-2% of all pancreatic tumors and have a general female predominance. We report a case and intraoperative videos of SPN involving the whole pancreatic tail. A 19-year-old female patient initially presented to another healthcare facility complaining of abdominal pain, which was started 6 years ago. A contrast-enhanced Computed Tomography (CT) scan of the abdomen showed a large mass measuring 15.6 cm × 11.6 cm × 11 cm, arising from the pancreas with an enhancing cystic component. The patient underwent exploratory laparotomy, which revealed a huge mass occupying most of the abdominal cavity. Thus, we proceeded with a distal pancreatectomy and splenectomy. Intraoperatively, the frozen section showed that the mass had features of a solid pseudopapillary tumor of the pancreas with negative resection margins. The SPN diagnosis was confirmed by histopathology and immunohistochemistry. The pathophysiology behind the development of SPN and its cellular origin is still a matter of debate with multiple proposed hypotheses. SPNs are asymptomatic in almost 70% of all cases and usually discovered incidentally. The pre-operative diagnosis of SPNs remains a clinical challenge despite all the current advances in the diagnostic modalities. Surgical management with negative resection margins is the mainstay of treatment, even with metastasis and vascular invasion, surgical excision should be performed whenever feasible. The recurrence rate after surgical resection has been reported to be 3-9%. The prognosis of SPN limited to the pancreas is generally excellent with over 95% cure rate following complete surgical resection. SPN is a rare entity of a controversial origin but is considered as a low-grade malignancy. Surgical resection to achieve complete excision constitutes the mainstay of treatment, which mostly results in an excellent prognosis.

RESUMEN

BACKGROUND: Whole-body computed tomography (WBCT) has been a mainstay and an integral part of the evaluation of polytrauma patients in trauma centers and emergency departments (ED) for a comprehensive evaluation of the extent of injuries. However, routine use of WBCT remains controversial since it exposes patients to radiation and exponentially increases financial expense. The primary objective was to determine the rate of negative WBCT in polytrauma patients. PATIENTS AND METHODS: A retrospective cohort study was conducted at an academic hospital in the Kingdom of Saudi Arabia, which is a dedicated trauma center with a mean of 237,392 ED visits and 10,714 trauma per year. The study included all adult (≥18 years) polytrauma patients who presented to our ED, requiring trauma team activation, and underwent WBCT as part of their evaluation from January 2016 to May 2017. We excluded pediatric patients, patients transferred from another facility, and pregnant patients. The primary endpoint was to measure the rate of negative WBCT in polytraumatized patients. RESULTS: A total of 186 patients were included with a mean age of 28.8 ± 12.9 years. The rate of negative WBCT scans was 20.4%. The positive scans were subclassified based on the number of anatomical body regions that were affected radiologically. One body region was affected in 47 patients (31.8%), two body regions were affected in 50 patients (33.8%), and ≥3 body regions were affected in 51 patients (34.3%). In a subset analysis, we identified that oxygen saturation <94% and GCS ≤8 were associated with positive CT scans. CONCLUSION: Our study revealed a slightly higher rate of utilization of WBCT in the management of trauma patients compared to studies with similar practice. We believe that in the correct setting with incorporating high index of suspicion, a physical examination with attention to vital signs and mental status, performing E-FAST, and dedicated X-Rays is a way to potentially reduce the use of WBCT in polytrauma patients.

RESUMEN

INTRODUCTION: Retroperitoneal cystic lesions are uncommon heterogeneous clinical entities with no definite incidence. Their clinical presentations are different and their diagnosis is challenging. The management necessitates complete surgical excision, usually via laparotomy. Recently, laparoscopic approach is being increasingly used. CASE PRESENTATION: A 29-year-old female patient was referred for an incidentally-discovered huge retroperitoneal cyst. Imaging studies revealed a retroperitoneal cyst, measuring 13 * 11 cm. Diagnostic laparoscopy showed a retroperitoneal cyst displacing the small bowel and the right colon to the left side. The peritoneal covering was dissected from the cyst with caution not to cause cyst rupture. The cyst was removed partially using Endobag, then aspiration of its content to facilitate its delivery. The patient had a smooth uneventful postoperative course. DISCUSSION: The retroperitoneal space is large, expandable space which enables retroperitoneal cystic lesions to grow asymptomatic. CT scan remains the best imaging modality. Aspiration of its content is not routinely done as its sensitivity and specificity has been reported low. Moreover, it carries the risk of leakage of the cyst content into the peritoneal space. Open surgical complete excision is the traditional management and remains of choice. However, laparoscopic management can be tried with caution not to cause content spillage. Intraoperatively, controlled aspiration of the cyst helps in its retrieval. CONCLUSION: Primary retoperitoneal mucinous cystadenoma is a rare clinical entity that is usually incidentally discovered. Laparoscopic excision is safe and feasible if done by an expert laparoscopic surgeon. Care should always be taken not to cause spillage of its content.
