Acute, unintentional drug-related poisonings lead to an estimated 418,313 ED visits in 2014, according to the latest statistics from the Center for Disease Control and Prevention. While most of these were opiate-related poisonings, anticoagulant rodenticides were the most common cause of rodenticide-related poisoning in the United States. Many clinical syndromes and treatment algorithms have been described for patients with anticoagulant rodenticide poisoning. We report a case of an acute ingestion of two anticoagulant rodenticides and successful reversal of coagulation parameters using 4-factor prothrombin complex concentrate in a fixed-dose approach.

In March and April 2018, more than 150 patients presented to hospitals in Illinois with coagulopathy and bleeding diathesis. Area physicians and public health organizations identified an association between coagulopathy and synthetic cannabinoid use. Preliminary tests of patient serum samples and drug samples revealed that brodifacoum, an anticoagulant, was the likely adulterant.. We reviewed physician-reported data from patients admitted to Saint Francis Medical Center in Peoria, Illinois, between March 28 and April 21, 2018, and included in a case series adult patients who met the criteria used to diagnose synthetic cannabinoid-associated coagulopathy. A confirmatory anticoagulant poisoning panel was ordered at the discretion of the treating physician.. A total of 34 patients were identified as having synthetic cannabinoid-associated coagulopathy during 45 hospitalizations. Confirmatory anticoagulant testing was performed in 15 of the 34 patients, and superwarfarin poisoning was confirmed in the 15 patients tested. Anticoagulant tests were positive for brodifacoum in 15 patients (100%), difenacoum in 5 (33%), bromadiolone in 2 (13%), and warfarin in 1 (7%). Common symptoms at presentation included gross hematuria in 19 patients (56%) and abdominal pain in 16 (47%). Computed tomography was performed to evaluate abdominal pain and revealed renal abnormalities in 12 patients. Vitamin K. Our data indicate that superwarfarin adulterants of synthetic cannabinoids can lead to clinically significant coagulopathy. In our series, in most of the cases in which the patient presented with bleeding diathesis, symptoms were controlled with the use of vitamin K

Despite the increasing use of fatty meal (FM) as a substitute for cholecystokinin (CCK) in pain reproduction during hepato-imino-diacetic acid (HIDA) scan in functional gallbladder disorder, there are no studies comparing the differences between CCK and FM. The present study was to compare the efficacy of FM in comparison of CCK in FGBD application.. Patients undergoing HIDA scans from August 2013 to May 2014 were divided into two groups: those undergoing CCK-stimulated HIDA scan versus FM-stimulated HIDA scan. These groups were compared according to demographics and HIDA results.. Of 153 patients, 70 received CCK and 83 FM. There was no difference regarding age, gender, gallstones, gallbladder ejection fraction and time to visualization. However, significantly more of the patients receiving CCK than FM experienced pain reproduction (61% vs 30%, P<0.01).. Stimulation of gallbladder contractility with a FM during HIDA is less than half as likely to reproduce biliary symptoms compared to CCK, despite similar ejection fractions and other parameters. It is essential that providers account for this difference when counseling patients regarding cholecystectomy for functional gallbladder disorder.

Long-acting anticoagulant rodenticides, also called superwarfarins, are known for their greater potency, longer half-life and delayed onset of symptoms. Cases of superwarfarin poisoning can pose a diagnostic and clinical challenge due to a wide array of presentations and prolonged severe coagulopathy requiring months of high-dose oral vitamin K therapy. The most common presentation of long-acting anticoagulant rodenticide poisoning is mucocutaneous bleeding, with other common presentations including haematuria, gingival bleeding, epistaxis and gastrointestinal bleeding. We discuss a case of deliberate self-poisoning with long-acting anticoagulant rodenticides presenting with haematuria and coagulation values above measurable limits. This case is important as it required immediate and maintenance therapy in order to prevent profound bleeding, as well as the evaluation of the patient's psychosocial factors to ensure medical compliance and to prevent refractory complications or repeated self-harm.

The optimal initial treatment of splanchnic vein thrombosis is uncertain. Anticoagulant therapy has been shown to be associated with vessel recanalization and decreased recurrence. Furthermore, information regarding potential predictors of chronic complications is not well understood.. A retrospective cohort study involving consecutive patients diagnosed with first-episode noncirrhotic splanchnic vein thrombosis referred to the thrombosis clinic of the authors' institution between 2008 and 2011 was conducted. Demographic and clinical information was collected. The response to initial anticoagulant therapy was evaluated by determining radiographic recanalization of vessels and clinical resolution (defined as the absence of ongoing splanchnic vein thrombosis symptoms or complications requiring treatment beyond anticoagulant therapy).. Twenty-two patients were included. Anticoagulant therapy alone resulted in vessel recanalization in 41% of patients and 68% achieved clinical resolution. Two patients experienced bleeding events. Factors associated with a lack of clinical resolution included signs of portal hypertension⁄liver failure on presentation, complete vessel occlusion at diagnosis, presence of a myeloproliferative disorder or JAK2V617F tyrosine kinase mutation and the absence of a local⁄transient predisposing factor.. Anticoagulant therapy appeared to be an effective initial treatment in patients with splanchnic vein thrombosis. Clinical factors may help to identify patients who are at risk for developing complications thus requiring closer monitoring. These findings were limited by the small sample size and need to be explored in larger prospective studies.

Iliopsoas haematoma is a rare complication that occurs in patients receiving anticoagulant therapy. The clinical manifestation of iliopsoas haematoma is non-specific. It can mimic orthopaedic or neurological disorders, including paraesthesia or paresis of the thigh and leg due to compression of the nerve plexus. Among the many available diagnostic modalities, computed tomography is the most useful radiological method for diagnosis. Treatment approaches for iliopsoas haematoma include conservative therapy, surgical intervention, or transcatheter arterial embolisation. Conservative therapy consists of bed rest, restoration of circulating volume, and drug discontinuation for correcting underlying coagulopathy. Although a conservative approach is the first choice, transcatheter arterial embolisation and surgical intervention may be required in patients with hemodynamically unstable and active bleeding. The report described a case of iliopsoas haematoma due to anticoagulant therapy with paraesthesia in the left leg who was successfully treated by conservative approach.

Rectus sheath hematoma (RSH) is a known complication of anticoagulation therapy and a source of potential morbidity and mortality. Early diagnosis and appropriate treatment may help to prevent complications including hemodynamic instability, the abdominal compartment syndrome or multiorgan dysfunction. Although the diagnosis can be made clinically, it can be confirmed with computed tomography of the abdomen. Most patients can be managed conservatively; however, it is often necessary to suspend anticoagulation in the acute setting. Rectus sheath hematoma is not a contraindication to resuming anticoagulation once the hematoma has been adequately managed and the patient has returned to a stable clinical baseline.

Although a bleeding tendency as a first symptom is a critical condition in congenital biliary dilatation (CBD), the clinical details of this symptom remain unclear. We assessed this condition in children with CBD in this paper.. Sixty-five children with CBD were treated at our institute between 1983 and 2004. The children, initially presenting with bleeding manifestations such as intracranial hemorrhage and bloody stools, were defined as the bleeding group, and the remaining children with digestive symptoms such as abdominal pain and vomiting were defined as the digestive group. The clinical features were compared between these two groups.. In 6 of the 65 cases, bleeding manifestations were noted (9.2 %). All six had cystic-type choledochal dilatation. The mean age of the bleeding group was significantly younger than that of the digestive group, and bleeding was more frequent, especially in infants less than 12 months of age. In a laboratory study, the bleeding group showed a more prolonged blood coagulation time than the digestive group did. Serum amylase and lipase levels in the bleeding group were almost normal, while those in the digestive group were significantly higher. The direct bilirubin level in the bleeding group was significantly higher than that in the digestive group.. Disturbed blood coagulation due to vitamin K deficiency related to cholestasis results in a bleeding tendency in children with CBD. Therefore, pediatric surgeons should be aware of this rare but critical condition which can be prevented by rapid and precise treatment with vitamin K supplementation.
