    Abstract Abstract: Chiropractic cervical spinal manipulations have several complications and can result in vascular injury, including traumatic dissection of the vertebral arteries. A 43-year-old woman was admitted to the emergency department after performing a self-chiropractic spinal manipulation. She experienced headache and vomiting and was unresponsive with severe hypertension at the time of hospital admission. Clinical computerized tomography angiography showed narrowing of the right vertebral artery but was inconclusive for dissection or thrombosis. At autopsy, subacute dissection of the right vertebral artery was identified along with cerebral edema and herniation. A small peripheral pulmonary thromboembolism in the right lung was also seen. Neuropathology consultation confirmed the presence of diffuse cerebral edema and acute hypoxic-ischemic changes, with multifocal acute subarachnoid and intraparenchymal hemorrhage of the brain and spinal cord. This case presents a unique circumstance of a fatal vertebral artery dissection after self-chiropractic manipulation that, to the best of our knowledge, has not been previously described in the medical literature.

    Abstract Context.—: The diagnosis of some infectious diseases requires their identification in tissue specimens. As institutions adopt digital pathology for primary diagnosis, the limits of microorganism detection from digital images must be delineated.
    Objective.—: To assess the reliability of microorganism detection from digitized images of histochemical and immunohistochemical stains commonly used in pathology.
    Design.—: Original glass slides from 620 surgical pathology cases evaluated for the presence of infectious microorganisms were digitized. Immunohistochemical stains included those for herpes simplex virus (n = 100), cytomegalovirus (n = 100), Helicobacter pylori (n = 100), and spirochetes (n = 80). Histochemical stains included mucicarmine for Cryptococcus spp (n = 20), Grocott methenamine silver for fungi (n = 100), Giemsa for H pylori (n = 100), and Ziehl-Neelsen for acid-fast bacilli (n = 20). The original diagnosis based on the glass slides was regarded as the reference standard. Six pathologists reviewed the digital images.
    Results.—: Digital review was generally associated with high (ie, ≥90%) specificity and positive predictive value owing to a low percentage of false positive reads, whereas a high percentage of false negatives contributed to low sensitivity and negative predictive value for many stains. Fleiss κ showed substantial interobserver agreement in the interpretation of Grocott methenamine silver and immunostains for herpes simplex virus, H pylori, and cytomegalovirus; moderate agreement for spirochete, Ziehl-Neelsen, and mucicarmine; and poor agreement for Giemsa.
    Conclusions.—: Digital immunohistochemistry generally outperforms histochemical stains for microorganism detection. Digital interpretation of Ziehl-Neelsen and mucicarmine stains is associated with low scores for interrater reliability, accuracy, sensitivity, and negative predictive value such that it should not substitute for conventional review of glass slides.

    Abstract Dermatomyositis sine dermatitis (DMSD) is a rare autoimmune disease. It's distinguished from classical dermatomyositis (DM) by a lack of skin involvement. DM is known to have a variety of extramuscular manifestations, including interstitial lung disease, myocarditis, and dysphagia. However, peripheral nervous system involvement in DM termed "Neuromyositis" is less often encountered. Neuromyositis diagnosis is controversial due to its rarity, unknown mechanism, and heterogeneity of nerve pathology findings. A 53-year-old woman presented to our hospital following a fall. Six months prior to presentation, she had a sensory disturbance in her right foot. On admission, she had a right foot drop that progressed to right then left lower extremity weakness. A biopsy of the superficial peroneal nerve and long peroneal muscle showed large fiber nerve axonal loss, CD20 B-cell and CD4 T-cell predominant inflammatory infiltrate involving the perimysial connective tissue of the muscle, as well as myocyte hypertrophy and fibrosis with type I fiber predominance. These findings were compatible with dermatomyositis with neuropathic features. Electrophysiological studies of lower extremities revealed severe widespread axonal dysfunction, as evidenced by decreased tibial compound muscle action potential (CMAP), no peroneal motor responses, absent sural sensory nerve action potential (SNAP), and extensive active denervation throughout the left lower extremity. Three months later, she developed bilateral upper extremity weakness. A biopsy of the deltoid muscle that was done eight months after admission showed CD20 B-cell and CD4 T-cell predominant inflammatory infiltrates involving the perimysial connective tissue. These findings were pathologically similar to the first biopsy. Subsequently, a repeat electromyography (EMG) of upper extremities revealed myopathic changes with normal nerve conductions. She ultimately became quadriplegic and ventilator-dependent nine months after admission. She never exhibited any skin findings throughout her course of illness. An extensive imaging and laboratory workup did not reveal any occult malignancy, inflammation, or nutritional deficiency. Our patient did not respond to steroids or intravenous immunoglobulin (IVIg) and ultimately passed away. The clinical, pathological, and electrophysiological features suggested the presence of neuromyositis. This case illustrates the importance of recognizing peripheral nervous system involvement as a significant and yet underreported extramuscular manifestation of DM. There are currently no formal management guidelines for neuromyositis.

    Abstract Background: Dermatomyositis (DM) is an idiopathic inflammatory myopathy with various cutaneous manifestations. There is a strong association between DM and malignancy with an estimated 5–7 fold increase in cancer incidence in DM patients compared to the general population. Dermatomyositis as a paraneoplastic manifestation has been reported in several malignancies notably ovarian, gastric, colon, cervical, pancreatic, and lung cancer but rarely in prostate cancer ('Table 1'). Case Presentation: A 64-year-old male with a past medical history of hypertension, gout, and type II diabetes was admitted to the hospital following a mechanical fall after which he sustained shoulder and facial trauma. On further evaluation, the patient was found to have dysphagia, dysphonia, proximal upper extremity and lower extremity weakness, and rashes. The dysphagia began one month prior to presentation and the rashes appeared two months prior. Physical exam was notable for erythematous and scaly-dry skin in V-neck pattern, gottron papules, facial and periorbital erythema with scaly skin, periungual erythema, oropharyngeal salivary pooling, proximal bilateral upper and lower extremity weakness with intact distal extremity strength, and wasting of the bilateral quadriceps and hamstrings. Labs were notable for elevated creatine kinase (CPK) 296, positive Anti-p155/140 antibodies which are directed against transcription intermediate family-1 (TIF-1). Further workup with a computed tomography scan (CT) of the abdomen and pelvis revealed extensive pelvic and abdominal lymphadenopathy, centered in the pelvis, and therefore suspicious for either nodal metastasis from prostate adenocarcinoma versus lymphoma. A right inguinal lymph node biopsy was done and confirmed the diagnosis of metastatic adenocarcinoma of the prostatic primary. Staging workup via bone scan and MRI showed diffuse osseous metastases in the thoracolumbar spine ('Figure 1'). Consequently, the patient was started on Bicalutamide and Leuprolide as therapy for the underlying ...

    Abstract Abstract: Dermatomyositis (DM) is an autoimmune myopathy characterized by proximal muscle weakness and distinct skin findings. DM is associated with an increased risk of malignancy in adults. We describe a case of dermatomyositis with unusually severe oropharyngeal dysphagia and respiratory muscle weakness on presentation, who was found to have underlying metastatic prostate cancer. Prostate cancer is uncommonly associated with DM. The patient tested positive for antitranscription intermediate family-1 (anti-TIF-1, also known as anti-p155/410) antibodies, which are linked to malignancy-associated DM in adults and are associated with dysphagia and more severe cutaneous findings.

    Abstract Background: Prognostic indicators, treatments, and survival estimates vary by cancer type. Therefore, disease-specific models are needed to estimate patient survival. Our primary aim was to develop models to estimate survival duration after treatment for skeletal-related events (SREs) (symptomatic bone metastasis, including impending or actual pathologic fractures) in men with metastatic bone disease due to prostate cancer. Such disease-specific models could be added to the PATHFx clinical-decision support tool, which is available worldwide, free of charge. Our secondary aim was to determine disease-specific factors that should be included in an international cancer registry.
    Methods: We analyzed records of 438 men with metastatic prostate cancer who sustained SREs that required treatment with radiotherapy or surgery from 1989-2017. We developed and validated 6 models for 1-, 2-, 3-, 4-, 5-, and 10-year survival after treatment. Model performance was evaluated using calibration analysis, Brier scores, area under the receiver operator characteristic curve (AUC), and decision curve analysis to determine the models' clinical utility. We characterized the magnitude and direction of model features.
    Results: The models exhibited acceptable calibration, accuracy (Brier scores < 0.20), and classification ability (AUCs > 0.73). Decision curve analysis determined that all 6 models were suitable for clinical use. The order of feature importance was distinct for each model. In all models, 3 factors were positively associated with survival duration: younger age at metastasis diagnosis, proximal prostate-specific antigen (PSA) < 10 ng/mL, and slow-rising alkaline phosphatase velocity (APV).
    Conclusions: We developed models that estimate survival duration in patients with metastatic bone disease due to prostate cancer. These models require external validation but should meanwhile be included in the PATHFx tool. PSA and APV data should be recorded in an international cancer registry.

    Abstract Glioblastoma multiforme (GBM) is an aggressive tumour that can lead to lymphopaenia. Its standard treatment involves temozolomide (TMZ) chemotherapy with radiation, often with addition of corticosteroids for symptomatic management. Although TMZ is also immunosuppressive, patients receiving TMZ rarely develop disseminated opportunistic infections. Here, we report the case of a patient with GBM receiving TMZ, radiotherapy and corticosteroids, who develops an incidental new brain lesion that is found to be disseminated

    Abstract Background: Cladophialophora bantiana is a dematiaceous, saprophytic fungus and a rare but reported cause of intracranial abscesses due to its strong neurotropism. Although it predominantly affects immunocompetent individuals with environmental exposure, more recently, its significance as a highly lethal opportunistic infection in transplant recipients has been recognized. Successful treatment requires timely but often challenging diagnosis, followed by complete surgical excision. Next-generation sequencing of microbial cell-free DNA (cfDNA) from plasma is a novel diagnostic method with the potential to identify invasive fungal infections more rapidly and less invasively than conventional microbiological testing, including brain biopsy.
    Observations: The authors described the case of a recipient of a liver transplant who presented with seizures and was found to have innumerable ring-enhancing intracranial lesions. The Karius Test, a commercially available method of next-generation sequencing of cfDNA, was used to determine the causative organism. Samples from the patient's plasma identified C. bantiana 6 days before culture results of the surgical specimen, allowing optimization of the empirical antifungal regimen, which led to a reduction in the size of the abscesses.
    Lessons: The authors' findings suggest that microbial cfDNA sequencing may be particularly impactful in improving the management of brain abscesses in which the differential diagnosis is wide because of immunosuppression.
