BACKGROUND
Colchicine is a common therapeutic agent for inflammatory conditions such as gout, yet its narrow therapeutic range frequently results in cases of overdose and subsequent poisoning. Acute colchicine poisoning can be difficult to identify due to its nonspecific clinical manifestations, posing a diagnostic challenge for emergency physicians without a clear history of colchicine ingestion.
CASE PRESENTATION
This report describes a tragic case of acute colchicine poisoning that resulted in three familial homicides. The patients presented with fever, abdominal pain, and diarrhea, which rapidly escalated to shock during their emergency department visits. Laboratory tests revealed a marked leukocytosis, mild elevation in procalcitonin (PCT), significantly elevated creatine kinase (CK) and CK-MB levels, and liver function abnormalities. Despite treatment with carbapenem antibiotics and aggressive fluid resuscitation, the patients' condition deteriorated, marked by a progressive decline in leukocytes and neutrophils. Initially misdiagnosed as septic shock, the ineffectiveness of the standard treatment protocols led to a fatal outcome for all three individuals.
CONCLUSION
Emergency physicians should consider acute colchicine poisoning as a differential diagnosis in patients presenting with shock and the following clinical indicators: (1) pronounced increase in peripheral leukocytes with a disproportionate rise in neutrophils; (2) discordance between the level of serum procalcitonin and the severity of presumed septic shock; (3) early increase in serum creatine kinase (CK) and CK-MB; (4) poor response to antibiotics and resuscitative efforts, accompanied by a continuous decrease in white blood cells and neutrophils. This case underscores the critical need for awareness of colchicine toxicity in the emergency setting, particularly when the clinical presentation mimics septic shock but fails to respond to standard treatments.

In solid tumors, hypereosinophilia is a rare phenomenon and is mainly associated with mucin-secreting carcinomas. Thyroid tumors associated with neutrophilia and/or eosinophilia have been described exclusively in patients with anaplastic thyroid cancer. Eosinophilia associated with papillary thyroid cancer is extremely rare and there are very few cases currently described. It has been suggested that three cytokines, namely interleukin-3 (IL-3), interleukin-5 (IL-5), and granulocyte-macrophage colony-stimulating factor (GM-CSF), may act as a peptide potential eosinophilic. To date, only three patients with differentiated thyroid cancer associated with eosinophilia have been reported, two of the papillary type and one of the medullary type. A 48-year-old patient consulted in 2022 due to bilateral cervical lymphadenopathy of 3 years' duration associated with wasting syndrome and hypereosinophilia. PET CT was requested, which showed hypermetabolic focus in the right thyroid lobe and lymph node, lung, bone, and liver metastases; Thyroid ultrasound showing a nodule of high suspicion of malignancy and a conglomerate of lymphadenopathy in the right lobe with positive needle wash for thyroglobulin. Hypereosinophilia was evaluated with initial leukocytosis values of GB 30,310/mm3 (10,608/mm3 of eosinophils) to maximum values of GB 77,090/mm3 (eosinophils 20,814/mm3). It was interpreted as paraneoplastic syndrome and corticosteroid therapy was started at immunosuppressive doses without response. Our observations presented in this article are in line with most studies reflecting that paraneoplastic hypereosinophilia is characterized by more advanced disease and poor prognosis.

Admission Total Leukocyte Count as a Predictor of Mortality in Cardiac Intensive Care Unit Patients.JACC. Advances Jan 2024Inflammation is a sequela of cardiovascular critical illness and a risk factor for mortality.
BACKGROUND
Inflammation is a sequela of cardiovascular critical illness and a risk factor for mortality.
OBJECTIVES
This study aimed to evaluate the association between white blood cell count (WBC) and mortality in a broad population of patients admitted to the cardiac intensive care unit (CICU).
METHODS
This retrospective cohort study included patients admitted to the Mayo Clinic CICU between 2007 and 2018. We analyzed WBC as a continuous variable and then categorized WBC as low (<4.0 × 10/mL), normal (≥4.0 to <11.0 × 10/mL), high (≥11.0 to <22.0 × 10/mL), or very high (≥22.0 × 10/mL). The association between WBC and in-hospital mortality was evaluated using multivariable logistic regression and random forest models.
RESULTS
We included 11,699 patients with a median age of 69.3 years (37.6% females). Median WBC was 9.6 (IQR: 7.4-12.7). Mortality was higher in the low (10.5%), high (12.0%), and very high (33.3%) WBC groups relative to the normal WBC group (5.3%). A rising WBC was incrementally associated with higher in-hospital mortality after adjustment (AICc adjusted OR: 1.03 [95% CI: 1.02-1.04] per 1 × 10 increase in WBC). After adjustment, only the high (AICc adjusted OR: 1.37 [95% CI: 1.15-1.64]) and very high (AICc adjusted OR: 1.99 [1.47-2.71]) WBC groups remained associated with increased risk of in-hospital mortality.
CONCLUSIONS
Leukocytosis is associated with an increased mortality risk in a diverse cohort of CICU patients. This readily available marker of systemic inflammation may be useful for risk stratification within the increasingly complex CICU patient population.

There have been no case reports of non-occlusive mesenteric ischemia (NOMI) following head trauma. Our two patients with non-surgical traumatic intracerebral hemorrhage succumbed to NOMI one week after the injury. Both were women over age 80 years and were clinically improving before NOMI occurred. One patient had been eating since admission, while the other had not, which prompted the initiation of enteral nutrition on day 5. The patients shared many characteristics: 1) over age 80 years; 2) minor brain contusion; 3) constipation for a week; 4) minimal abdominal symptoms; 5) rapidly developing leukocytosis, hyperglycemia, hypernatremia, and elevated blood urea nitrogen; 6) massive diarrhea with a small amount of blood on the same day that laboratory data became abnormal; and 7) fever and shock developed shortly after diarrhea appeared. Because of the fulminant worsening of the condition, shock status, and old age, surgical intervention was considered high risk and not performed in either patient. In retrospect, if NOMI had been diagnosed earlier when the acute pancreatitis-like symptoms began, surgical intervention may have saved their lives. Clinicians should be aware that NOMI can occur after relatively minor head trauma, which can cause death if the diagnosis is delayed.

BACKGROUND
Radicular pain is the most predominant symptom among adults with Lyme neuroborreliosis (LNB) but the duration preceding and following diagnosis remains unknown. We aimed to investigate whether patients with LNB have increased obtainment of analgesics before and after diagnosis and for how long.
METHODS
We performed a nationwide, population-based, matched cohort study (2009-2021). all Danish residents with LNB (positive Borrelia burgdorferi intrathecal antibody index test and cerebrospinal fluid pleocytosis) were included. To form a comparison cohort, individuals from the general population were randomly extracted and matched 10:1 to patients with LNB on age and sex. Outcomes were obtainment of simple analgesics, antiepileptics, tricyclic antidepressants, serotonin and noradrenaline reuptake inhibitors, tramadol, and other opioids. We calculated monthly and six-monthly proportions of individuals with obtainment of analgesics and absolute risk differences.
RESULTS
1,056 patients with LNB and 10,560 comparison cohort members were included. An increased proportion of patients with LNB obtained analgesics from 3 months before study inclusion, especially simple analgesics, tramadol, and other opioids. Within the 0-1-month period after study inclusion, patients with LNB most frequently obtained simple analgesics (15 %), antiepileptics (11 %), and tramadol (10 %). Thereafter, obtainment of analgesics declined within a few months. A slightly larger proportion of patients with LNB obtained antiepileptics up to 2.5 years after diagnosis.
CONCLUSIONS
Up to 3 months preceding diagnosis, LNB was preceded by increased obtainment of analgesics, which suggests diagnostic delay. Importantly, most patients with LNB did not obtain analgesics after the immediate disease course, although obtainment remained more frequent up to 2.5 years after.

Hypovitaminosis D and Leukocytosis to Predict Cardiovascular Abnormalities in Children with Kawasaki Disease: Insights from a Single-Center Retrospective Observational Cohort Study.
An aberrant immune response involving yet unidentified environmental and genetic factors plays a crucial role in triggering Kawasaki disease (KD). The aim of this study was to assess general and laboratory data at the onset of KD in a single-center cohort of children managed between 2003 and 2023 and retrospectively evaluate any potential relationship with the development of KD-related cardiovascular abnormalities (CVAs). We took into account a total of 65 consecutive children with KD (42 males, median age: 22 months, age range: 2-88 months) followed at the Department of Life Sciences and Public Health in our University; demographic data, clinical signs, and laboratory variables at disease onset, before IVIG infusion, including C-reactive protein, hemoglobin, white blood cell (WBC) count, neutrophil count, platelet count, aminotransferases, natremia, albumin, total bilirubin, and 25-hydroxyvitamin D were evaluated. Twenty-one children (32.3% of the whole cohort) were found to have echocardiographic evidence of CVAs. Univariate analysis showed that diagnosis of KD at <1 year or >5 years was associated with CVAs ( = 0.001 and = 0.01, respectively); patients with CVAs had a longer fever duration and mostly presented atypical or incomplete presentations. Interestingly, all patients with CVAs had lower levels of vitamin D (less than 30 mg/dL, = 0.0001) and both higher WBC and higher neutrophil counts than those without CVAs ( = 0.0001 and = 0.01, respectively). Moreover, blood levels of albumin were significantly lower in KD patients with CVAs compared to those without (11/21, 52% versus 13/44, 30%, = 0.02). Multiple logistic regression with correction for sex showed that serum vitamin D < 30 ng/mL, WBC count > 20.000/mm, and age > 60 months at KD onset were the only independent factors statistically associated with CVAs. Hypovitaminosis D, WBC count over 20.000/mm, and age above 5 years at KD onset emerged as independent factors statistically associated with the occurrence of CVAs.

In the present case report, we describe the clinical course and postmortem findings of a 12-year-old Labrador retriever dog with a third-degree atrio-ventricular block that developed a chronic cough, and later dyspnea and weakness as a result of massive pulmonary thromboembolism 3 years after implantation of a transvenous permanent pacemaker. A large soft tissue mass was seen in the right ventricular chamber around the pacing lead with echocardiography. Initially, this was thought to be caused by mural bacterial endocarditis based on hyperthermia, severe leukocytosis and the appearance of runs of ventricular tachycardia, the latter suggesting myocardial damage. While blood culture results were pending, antibiotics were administered without a positive effect. Due to clinical deterioration, the owner elected for euthanasia and a post-mortem examination confirmed a right ventricular thrombus and surrounding myocarditis, without signs of bacterial infection, and a massive pulmonary thromboembolism. We conclude that pulmonary thromboembolism should be considered in dogs with a cough that have an endocardial pacing lead implanted. Serial screening for proteinuria before and after implantation of an endocardial pacing lead would allow timely initiation of prophylactic antiplatelet therapy. Local myocarditis can develop secondary to an intracavitary thrombus, which can subsequently lead to runs of ventricular tachycardia.

Leukocytosis in neonates can occur because of infectious, inflammatory, malignant, or physiological processes. Hyperleukocytosis is defined as a total leukocyte count (TLC) exceeding 100,000 per mm, warranting immediate evaluation. Neonates with hyperleukocytosis are at risk of leukostasis and the associated severe complications, including respiratory distress, myocardial ischemia, hyperuricemia, acute renal failure, infarction, and hemorrhage. Differentiating leukemia and leukemoid reactions in neonates presenting with elevated TLC is challenging but critical. We present a unique case of a preterm male neonate with hyperleukocytosis, initially suspected to have an underlying malignancy. The neonate's clinical course was complicated by respiratory distress syndrome and anemia of prematurity, necessitating neonatal intensive care unit management. Further investigation revealed high human herpesvirus 6 (HHV-6) DNA levels in the whole blood, leading to a chromosomally integrated HHV-6 (ciHHV-6) diagnosis. CiHHV-6 is characterized by HHV-6 DNA integration into the host genome. Accurate diagnosis relies on whole-blood quantitative PCR, distinguishing ciHHV-6 from an active infection. The neonate remained asymptomatic, and antiviral treatment was deemed unnecessary. This case underscores the importance of recognizing ciHHV-6 as a potential cause of hyperleukocytosis in neonates and highlights the value of whole-blood PCR for differentiation. Understanding the spectrum of HHV-6 infection in neonates is vital for appropriate management and prognostication.

Acute transverse myelitis (ATM) is a syndrome of multiple etiologies, with acute or subacute onset in which inflammation of the spinal cord results in neurological deficits, including weakness, sensory loss, and autonomic dysfunction. It is often associated with infectious or autoimmune etiologies but can be considered idiopathic when extensive workup is negative. We present a case of a young African American female who presented with acute onset of bilateral lower extremity weakness, loss of sensation, and autonomic dysfunction. On physical exam, she had absent lower extremity reflexes, 0-1/5 power, and markedly diminished sensation with no pain/temperature discrimination with an abdominal sensory level at T4. There was no upper extremity involvement. She was incidentally found to be COVID-19-positive and denied ever being vaccinated in the past. MRI of the spine revealed diffuse signal abnormality within the cervical and thoracic spine extending to the conus, and an MRI of the brain showed two white matter lesions in the frontal lobes. Lumbar puncture showed lymphocytic pleocytosis and elevated protein; Gram stain did not reveal any pathogen. The patient was treated initially with high doses of steroids with minimal response. She underwent multiple sessions of plasmapheresis with good tolerance and response. Differential diagnoses considered for this case were Guillain Barre syndrome, neuromyelitis optica (NMO), multiple sclerosis, SLE-induced transverse myelitis, or infectious cases. All lab work and workup came back negative for these diseases, leaving us with an interesting culprit: COVID-19 associated. There have been few cases mentioned in the literature of transverse myelitis caused by COVID-19, and this remains a possibility, as all other causes were ruled out.
