A Unique Case of Cardiac Arrest following K2 Abuse

Sudden cardiac death (SCD) accounts for up to 450,000 deaths every year in the United States (Zipes et al. (2006)). Most cases of sudden cardiac death occur in subjects with no prior history of heart disease (Myerburg et al. (1998)). The incidence of sudden death in a general population has been shown to increase contemporaneously with substance abuse (Phillips et al. (1999)). The causative association of sudden death with cocaine, methadone, and volatile agents is well established (Adgey et al. (1995) and Isner et al. (1986)). We describe a case of out-of-hospital cardiac arrest temporally related to abuse of the synthetic cannabinoid street drug known as K2. To our knowledge, there are no previously documented cases of sudden cardiac death associated with synthetic cannabinoids although they have been linked to myocardial infarction in teenagers despite normal coronary angiography (Mir et al. (2011)).

Predicting the Need for Upfront Combination Therapy in Pulmonary Arterial Hypertension

Background: Combination therapy is commonly used for pulmonary arterial hypertension (PAH) treatment. We aimed to identify factors that may predict the need for future combination therapy. Methods: We conducted a retrospective chart review of consecutive patients with PAH in an aim to describe baseline clinical, echocardiogram, and hemodynamic characteristics of patients who eventually required combination therapy during the course of their disease and compared them to the ones who were maintained on monotherapy. Results: The monotherapy group was followed for an average of 31.8 ± 18.8 months and the combination therapy group was followed for an average of 28.7 ± 13.6 months. Among the 71 patients analyzed, a significantly higher number of patients who eventually required combination therapy belonged to World Health Organization functional class 3 (45% vs 37%) and 4 (23% vs 0) at baseline, compared with those on monotherapy (P < .05). Combination group also had a higher Registry to Evaluate Early And Long-term PAH Disease Management (REVEAL) PAH risk score at presentation. End of 6-minute walk test (6MWT), oxygen saturation (Spo 2) was also lower in the combination therapy group, 86% ± 8% versus 91% ± 7% (P < .05). Patients who eventually required combination therapy were more frequently noticed to have right ventricular enlargement, right atrial enlargement, and had a higher resting estimated right ventricular systolic pressure (RVSP). Right heart catheterization-derived hemodynamics data at baseline showed that the combination therapy group had a higher mean pulmonary artery (PA) pressure, lower pulmonary capillary wedge pressure, lower cardiac output, and higher pulmonary vascular resistance (PVR). On univariate analysis, only PVR ≥300 dyne·s/cm5, mean PA pressure of ≥40 mm Hg, estimated RVSP ≥ 60 mm Hg, PAH risk score ≥ 10, and end of 6MWT saturation of ≤ 90% were of significance. Conclusion: Patients with PAH who require combination therapy in the course of their disease have worse hemodynamics, PAH risk score, functional class, and end of 6MWT oxygen saturation at the time of presentation compared to patients maintained on monotherapy.

Is There Any Association between PEEP and Upper Extremity DVT

Background. We hypothesized that positive end-exploratory pressure (PEEP) may promote venous stasis in the upper extremities and predispose to upper extremity deep vein thrombosis (UEDVT). Methods. We performed a retrospective case control study of medical intensive care unit patients who required mechanical ventilation (MV) for >72 hours and underwent duplex ultrasound of their upper veins for suspected DVT between January 2011 and December 2013. Results. UEDVT was found in 32 (28.5%) of 112 patients. Nineteen (67.8%) had a central venous catheter on the same side. The mean ± SD duration of MV was 13.2 ± 9.5 days. Average PEEP was 7.13 ± 2.97 cm H2O. Average PEEP was ≥10 cm H2O in 23 (20.5%) patients. Congestive heart failure (CHF) significantly increased the odds of UEDVT (OR 4.53, 95% CI 1.13–18.11; P = 0.03) whereas longer duration of MV (≥13 vs. <13 days) significantly reduced it (OR 0.29, 95% CI 0.11–0.8; P = 0.02). Morbid obesity showed a trend towards significance (OR 3.82, 95% CI 0.95–15.4; P = 0.06). Neither PEEP nor any of the other analyzed predictors was associated with UEDVT. Conclusions. There is no association between PEEP and UEDVT. CHF may predispose to UEDVT whereas the risk of UEDVT declines with longer duration of MV.

Achieving timely percutaneous reperfusion for rural ST-elevation myocardial infarction patients by direct transport to an urban PCI-hospital

Backgrounds ST-elevation myocardial infarction (STEMI) guidelines recommend reperfusion by primary percutaneous coronary intervention (PCI) ≤ 90 min from time of first medical contact (FMC). This strategy is challenging in rural areas lacking a nearby PCI-capable hospital. Recommended reperfusion times can be achieved for STEMI patients presenting in rural areas without a nearby PCI-capable hospital by ground transportation to a central PCI-capable hospital by use of protocol-driven emergency medical service (EMS) STEMI field triage protocol. Methods Sixty STEMI patients directly transported by EMS from three rural counties (Nassau, Camden and Charlton Counties) within a 50-mile radius of University of Florida Health-Jacksonville (UFHJ) from 01/01/2009 to 12/31/2013 were identified from its PCI registry. The STEMI field triage protocol incorporated three elements: (1) a cooperative agreement between each of the rural emergency medical service (EMS) agency and UFHJ; (2) performance of a pre-hospital ECG to facilitate STEMI identification and laboratory activation; and (3) direct transfer by ground transportation to the UFHJ cardiac catheterization laboratory. FMC-to-device (FMC2D), door-to-device (D2D), and transit times, the day of week, time of day, and EMS shift times were recorded, and odds ratio (OR) of achieving FMC2D times was calculated. Results FMC2D times were shorter for in-state STEMIs (81 ± 17 vs. 87 ± 19 min), but D2D times were similar (37 ± 18 vs. 39 ± 21 min). FMC2D ≤ 90 min were achieved in 82.7% in-state STEMIs compared to 52.2% for out-of-state STEMIs (OR = 4.4, 95% CI: 1.24–15.57; P = 0.018). FMC2D times were homogenous after adjusting for weekday vs. weekend, EMS shift times. Nine patients did not meet FMC2D ≤ 90 min. Six were within 10 min of target; all patient achieved FMC2D ≤ 120 min. Conclusions Guideline-compliant FMC2D ≤ 90 min is achievable for rural STEMI patients within a 50 mile radius of a PCI-capable hospital by use of protocol-driven EMS ground transportation. As all patients achieved a FMC2D time ≤ 120 min, bypass of non-PCI capable hospitals may be reasonable in this situation.

How an Opportunistic Infection Can Mess with Your Brain and Take Your Breath Away: A Rare Case of Simultaneous Lung and Brain Abscess due to Streptococcus anginosus

Streptococcus anginosus (S. anginosus) is considered a friendly bug and is a one of many different bacteria that constitute the normal flora of the oral cavity. Nevertheless, it has been infrequently associated with more invasive infections, like lung abscess. It is extremely rare to have multisystemic involvement with S. anginosus group. We present a unique case of pulmonary and brain abscess due to S. anginosus in an immunocompetent patient.

Pin Worms Presenting as Suspected Crohn's Disease.

Patient: Female, 24 Final Diagnosis: Pinworms infection Symptoms: Abdominal pain • bloating Medication: — Clinical Procedure: Colonoscopy and biopsy Specialty: Gastroenterology and Hepatology Objective: Rare disease Background: Inflammatory bowel disease (IBD) is well recognized in developed countries and is generally among the differential diagnoses of young patients presenting with refractory diarrhea once other more common etiologies have been excluded. Pinworm infections, on the other hand, are not as common among adults in the United States. Case Report: Based on computed tomography features, a 24-year-old female patient with a history of multiple autoimmune disorders presented with abdominal pain and was diagnosed recently with Crohn’s disease. Colonoscopy was significant for pinworms seen throughout the colon. Colonic biopsy was negative for inflammatory bowel disease (IBD)-related changes. Conclusions: The diagnosis of IBD is a serious label that requires biopsy confirmation before committing to possibly lifelong treatment and possible adverse effects. Even in the most typical patient and when the presentation and imaging are classical, uncommon conditions (like Enterobius infection in this case) may preclude appropriate diagnosis and management.

Rapid Progressive Seeding of a Community Acquired Pathogen in an Immune-Competent Host: End Organ Damage from Head to Bone

Methicillin-sensitive Staphylococcus aureus (MSSA) meningitis is a rare disease when not related to neurosurgery: there are only few reported cases in the literature to date. We describe a case that highlights not only meningeal but also diffuse and rapidly progressive systemic involvement with multi-organ failure. A 64-year-old male presented to our hospital with a chief complaint of acute worsening of his usual chronic lower back pain, progressive weakness in lower extremities and subjective fevers at home. Hospital course demonstrated MSSA bacteremia, of questionable source, that resulted in endocarditis affecting right and left heart in a patient with no history of intravenous drug use. The case was complicated by septic emboli to systemic circulation involving the kidneys, vertebral spine, lungs and brain with consequent meningitis and stroke, even when treated empirically with vancomycin and then switched to nafcillin as indicated. Even though MSSA infections are well known, there are very few case reports describing such an acute-simultaneous-manifestation of multi-end-organ failure, including meningitis and stroke. Our case, also presented with an uncommon manifestation of persistent infection dissemination despite adequate antibiotic treatment.

Potts Puffy Tumor: A New Complication of HIV

Background: First described in 1760, Pott’s Puffy Tumor (PPT) is frontal bone osteomyelitis and sub-periosteal abscess complicated by frontal sinusitis. Currently, it’s a very rare complication due to the advent of Antibiotics and even more rare in adults than adolescents as developmental differences in cranial anatomy have been presumed to be the reason why more cases are seen in the younger age group. Only 32 adult cases are reported since 1990 to date. Most common organisms being streptococci, staphylococci, and anaerobes. The Case: 51 year old African American male patient presented with worsening frontal headache and a painful swelling on the forehead along with diplopia. Past history is positive for HIV, diagnosed 7 years earlier, not on antiretroviral therapy, in addition to surgery for head trauma 13 years prior. With appropriate medical and surgical management, the patient had significant improvement on examination and his diplopia resolved. Cultures from drainage grew Propioni bacterium sp. Discussion: We present a unique case of PPT on a patient with a history of head trauma and HIV, both acting as predisposing factors for his delayed presentation. This link may suggest a possible epidemiological transition in the trends of comorbidities predisposing to PPT since HIV prevalence has been in the rise. It is also a case with the longest documented latency period between head trauma and PPT presentation date. This, combined with unusual anaerobic bacterial isolates, make this new case report a pioneer in pointing out PPT’s association with novel risk factors.
