Management of Drug-Induced Epidermal Necrolysis (DEN) in Pediatric Patients: Moving from Drug-Induced Stevens-Johnson Syndrome, Overlap and Toxic Epidermal Necrolysis to a Single Unifying Diagnosis of DEN.

Pediatric Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare but life-threating blistering diseases triggered by medications that affect the skin and mucosae. Drug-induced epidermal necrolysis is a better term for medication-triggered cases because there is a spectrum of disease severity that otherwise is divided into the separate entities of SJS, overlap SJS/TEN, and TEN. This manuscript reviews the management of drug-induced epidermal necrolysis (DEN), including diagnosis, investigations to exclude differential diagnoses, and treatment. Diagnosis of DEN relies on clinical features and a detailed medication history. The primary differential diagnosis is reactive infectious mucocutaneous eruption, which can be clinically distinguished by its disproportionate mucous membrane involvement relative to (sparse or absent) skin lesions. Identification and discontinuation of culprit medications is the mainstay of treatment of DEN. Early initiation of immunomodulatory therapy may prevent progression, reducing maximal disease severity and the risk of sequelae. A checklist approach to detailed management of DEN is proposed.

Giant pilomatrixoma on the back of neck: a unique case

<p class="abstract">Pilomatrixomas are benign adnexal tumours, commonly occurring in the head and neck region. We present a unique case of giant pilomatrixoma on the posterior triangle of the neck, its diagnosis and subsequent treatment and its potential to become a primary differential diagnosis of slow-growing, benign masses. We report a case of 10×10 cm slow-growing painless mass in the nape of the neck with overlying ulcerations and conflicting radio-pathological pre-operative reports and its subsequent diagnosis as pilomatrixoma. Histopathological examination revealed the presence of ghost cells and basaloid cells, confirming the diagnosis. We stress the importance of recognizing this pilomatrixoma variant, whose clinical picture is confusing and obscure<strong>. </strong>We also reiterate the need for close follow up of small lesions due to the small but grave risk of malignant transformation and recurrence. Pilomatrixoma has variable presenting features and poses a diagnostic dilemma. Surgical planning can be done with the help of proper radiological features, and complete excision of the mass is required to achieve a cure.</p>

Surgery in Autoimmune Pancreatitis

Introduction: Autoimmune pancreatitis (AIP) is a disease that may mimic malignant pancreatic lesions both in terms of symptomatology and imaging appearance. The aim of the present study is to analyze experiences of surgery in patients with AIP in one of the largest European cohorts. Patients and Methods: We performed a single-center retrospective study of patients diagnosed with AIP at the Department of Abdominal Diseases at Karolinska University Hospital in Stockholm, Sweden, between January 2001 and October 2020. Results: There were 159 patients diagnosed with AIP, and among them, 35 (22.0%) patients had surgery: 20 (57.1%) males and 15 (42.9%) females; median age at surgery was 59 years (range 37–81). Median follow-up period after surgery was 50 months (range 1–235). AIP type 1 was diagnosed in 28 (80%) patients and AIP type 2 in 7 (20%) patients. Malignant and premalignant lesions were diagnosed in 8 (22.9%) patients for whom AIP was not the primary differential diagnosis, but in all cases, it was described as a simultaneous finding and recorded in retrospective analysis in histological reports of surgical specimens. Conclusions: Diagnosis of AIP is not always straightforward, and in some cases, it is not easy to differentiate it from the malignancy. Surgery is generally not indicated for AIP but might be considered in patients when suspicion of malignant/premalignant lesions cannot be excluded after complete diagnostic workup.

BT-1 An autopsy case of multicentric malignant glioma, H3K27M mutant

Introduction: In 2016, the World Health Organization (WHO) defined diffuse midline glioma, H3K27M mutant (WHO Grade 4) as a tumor with K27M mutation in histone H3.3 (H3F3A) or H3.1 (HIST1H3B/C) that develops mainly in the midline regions of the central nervous system. Here, we report a rare case of the abovementioned disease with remote multiple lesions in addition to the midline regions that was diagnosed on the initial visit. Case: The 52-year-old man, suffered from dysarthria, dysphagia, gait disturbance, and headache that gradually worsened over several months. Non-contrast-enhanced lesions were noted in the pons(swelling and involvement of the basilar artery trunk), cerebellum, thalamus, fornix, periventricular area, hippocampus, medial aspect of bilateral frontal lobes, and distally in the right frontal cortex and apical region of the left temporal lobe. The open biopsy was performed for left cerebellar surface lesion, and the pathological and genetic diagnosis was diffuse midline glioma, H3K27M mutant. Extended focal radiation at 50Gy/25fr and corpus callosal/cerebellar boost at 10Gy/5fr were performed. The lesions were markedly reduced, and neurological symptoms were also alleviated. However, 20 months after the initial visit, neurological symptoms had worsened and cerebrospinal fluid dissemination occurred, after that died at 29 months. An autopsy revealed tumor invasion mainly in the midline regions of the cerebrum and in the cerebellum, brain stem, pituitary gland, entire spinal cord, and cauda equina. Immunostaining of the distally cerebral cortex lesions showed that with a negative result for H3G34V. Discussion/Conclusion: It was suggested that caution is required for primary differential diagnosis may be presented at multiple lesions such as remote cerebral cortex of diffuse midline glioma, H3K27M-mutant.

Imaging of Cerebral Microbleeds: Primary Patterns and Differential Diagnosis

Suspected local anaesthetic systemic toxicity (LAST) after several bupivacaine injections through an epidural catheter in a cat

AbstractA 9‐year‐old male neutered domestic short hair cat was referred to our practice after a road traffic accident. On presentation, the cat was obtunded, with bilateral hindlimb fractures. The fractures were surgically repaired, and an epidural catheter was placed for perioperative pain management. Postoperative analgesia consisted of bupivacaine administered intermittently through the epidural catheter. In the days after surgery, the cat became duller and more obtunded, and marked bilateral mydriasis with absence of a pupillary reflex was noted. After ruling out different causes for mydriasis and weaning the cat from systemic opioids, local anaesthetic systemic toxicity (LAST) emerged the primary differential diagnosis. Bupivacaine plasma concentrations were measured and found a fourfold increase in concentration over that reported after a perineural block. Mydriasis and absent pupillary light reflex, among other clinical signs, could be early indicators of LAST secondary to accumulation of the local anaesthetic in patients with an epidural catheter.

Identification of Mycoplasma species and related organisms from ruminants in England and Wales during 2005\u20132019

BackgroundMycoplasma species have been associated with economically important diseases affecting ruminants worldwide and include contagious bovine pleuropneumonia (CBPP), contagious caprine pleuropneumonia (CCPP) and contagious agalactia, listed by the World Organisation for Animal Health (OIE). The Mycoplasma Team at the Animal and Plant Health Agency provides an identification service for Mycoplasma and Ureaplasma species of veterinary importance to the United Kingdom (UK), supporting the detection of new and emerging pathogens, as well as contributing to the surveillance of endemic, and the OIE listed diseases exotic to the UK. Mycoplasma and other Mollicutes species were identified from diagnostic samples from farmed ruminants in England and Wales using a combination of culture and 16S rRNA gene-based PCR-denaturing gradient gel electrophoresis, submitted between 2005 and 2019.ResultsA total of 5578 mollicutes identifications, which include mycoplasmas and the related acholeoplasmas and ureaplasmas, were made from farmed ruminant animals during the study period. Throughout the study period, the pathogen Mycoplasma bovis was consistently the most frequently identified species, accounting for 1411 (32%) of 4447 molecular identifications in cattle, primarily detected in the lungs of pneumonic calves, followed by joints and milk of cattle showing signs of arthritis and mastitis, respectively. M. bovirhinis, M. alkalescens, M. dispar, M. arginini and Ureaplasma diversum, were also common. Mixed species, principally M. bovis with M. alkalescens, M. arginini or M. bovirhinis were also prevalent, particularly from respiratory samples. The non-cultivable blood-borne haemoplasmas Candidatus ‘Mycoplasma haemobos’ and Mycoplasma wenyonii were identified from cattle, with the latter species most often associated with milk-drop. M. ovipneumoniae was the predominant species identified from sheep and goats experiencing respiratory disease, while M. conjunctivae preponderated in ocular samples. The UK remains free of the ruminant mycoplasmas listed by OIE.ConclusionsThe continued high prevalence of M. bovis identifications confirms its ongoing dominance and importance as a significant pathogen of cattle in England and Wales, particularly in association with respiratory disease. M. ovipneumoniae has seen a general increase in prevalence in recent years, notably in coughing lambs and should therefore be considered as a primary differential diagnosis of respiratory disease in small ruminants.

Influence of 11C-MET PET acquisition time for differential diagnosis of human brain gliomas

The aim of this work was to study the effect of the reduced acquisition time of PET 11C-MET examination on the quality of primary brain tumors differential diagnosis. 57 patients with histologically verified diagnoses were recruited (glioblastoma n=20, anaplastic astrocytoma n=11, diffuse astrocytoma n=11, oligodendroglioma n=9 and anaplastic oligodendroglioma n=6). The scan time was varied in the range of 2-20 min. Our study demonstrated that in the case of intravenous administration of 11C-MET simultaneously with the start of scanning, the quality of primary gliomas differential diagnosis does not depend on the scan time. Therefor it becomes possible increasing the number of patients and reducing the acquisition time. The T/N60 ratio (T/N ratio measured in the first 60 seconds after 11C-MET intravenous injection) is equally successful parameter for glioma differential diagnosis as the traditional T/N ratio.

Investigation into clinicopathological and pathological findings, prognosis, and aetiology of lorikeet paralysis syndrome in rainbow lorikeets (Trichoglossus haematodus).

ObjectiveTo report the temporal and spatial distribution of rainbow lorikeets presenting with lorikeet paralysis syndrome (LPS) and their clinicopathologic and pathologic findings, exposure to toxins, and response to treatment.MethodsRecords of lorikeets admitted in 2017 and 2018 to facilities in south‐east Queensland (QLD) were reviewed and LPS and non‐LPS cases were mapped and their distribution compared. Plasma biochemistries and complete blood counts were done on 20 representative lorikeets from south‐east QLD and Grafton, New South Wales (NSW). Tissues from 28 lorikeets were examined histologically. Samples were tested for pesticides (n = 19), toxic elements (n = 23), botulism (n = 15) and alcohol (n = 5).ResultsLPS occurred in warmer months. Affected lorikeets were found across south‐east QLD. Hotspots were identified in Brisbane and the Sunshine Coast. Lorikeets had a heterophilic leucocytosis, elevated muscle enzymes, uric acid and sodium and chloride. Specific lesions were not found. Exposure to cadmium was common in LPS and non‐LPS lorikeets. Treated lorikeets had a 60–93% See Table 2 depending on severity of signs.Clinical significanceThe primary differential diagnosis for lorikeets presenting with lower motor neuron signs during spring, summer and autumn in northern NSW and south‐east Queensland should be LPS. With supportive care, prognosis is fair to good.

Distinguishing between toxic alcohol ingestion vs alcoholic ketoacidosis: how can we tell the difference?

Context Anion gap metabolic acidosis (AGMA) is common in patients presenting for emergency care. While some disease processes and ingestions are easily excluded, diagnosing toxic alcohol (TA) ingestion can be challenging. This is especially true if drug concentrations are not readily available, which forces clinicians to rely on surrogate markers. Like TA ingestion, alcoholic ketoacidosis (AKA) produces an elevated osmol gap and an AGMA. The aim of this study was to identify risk factors suggestive of AKA when TA ingestion was the primary alternative differential diagnosis. We hypothesized that the odds of an AKA diagnosis would increase as ethanol concentration increased. Methods This was a retrospective analysis of data from 2000 through 2019 from a single US Poison Control Center. Records were reviewed to identify cases coded as “methanol” or “ethylene glycol”; or coded as “alcohol” or “ethanol with acidosis.” The case definition for AKA required: (1) documented alcohol use disorder; (2) urine or serum ketones or elevated blood beta-hydroxybutyrate concentration; (3) anion gap ≥ 14 mmol/L. The inclusion criterion for TAs was a detectable methanol or ethylene glycol concentration. Results Of 699 patients screened, 86 were diagnosed with AKA and 36 were diagnosed with TA ingestion. As ethanol concentration increased, the odds of an AKA diagnosis significantly increased (OR = 1.016, 95% CI 1.002–1.031, p = .03). Conclusions In this retrospective analysis, the odds of diagnosing AKA instead of TA ingestion increased as ethanol concentration increased. The limited ability of common clinical factors to differentiate these diagnoses highlights the need to obtain quantitative TA concentrations in real time. Until prospective validation, interpretation of ketone concentrations and toxic alcohol concentrations (when available) will continue to guide decision making.

Duodenal peripapillary adenocarcinoma causing extrahepatic biliary obstruction and icterus in a cat

A six-year-old, female, neutered domestic shorthair cat was presented with chronic weight loss and a two-day history of partial anorexia and lethargy. Abdominal ultrasonography revealed a regional thickening of the duodenal wall with loss of normal layering, a normally walled segmentally dilated distal aspect of the common bile duct containing slightly hyperechoic bile, and a mild to moderately enlarged major duodenal papilla. Based on the ultrasound examination, the primary differential diagnosis was a peripapillary duodenal neoplastic or less likely, an inflammatory or infectious process with secondary extrahepatic biliary obstruction. Postmortem examination revealed a duodenal, peripapillary adenocarcinoma with metastasis into the liver and lymph nodes, and external compressive obstruction of cystic- and common bile duct.

Breast sarcoidosis: Clinical features, imaging, and histological findings.

Breast sarcoidosis is an extremely rare entity (about 1%). Conventional imaging significantly contributes to the detection of breast lesions, but it has been unable to establish a definite diagnosis. Histological examination should be mandatory, over imaging assessments, in order to confirm an early diagnosis and to avoid unjustified treatments. Malignancy should be excluded as a primary differential diagnosis. However, in the presence of granulomas, it is important to recognize other granulomatous disorders such as tuberculosis, Wegener's granulomatosis, or idiopathic granulomatous mastitis, since therapeutic strategies differ. This report clarifies the current clinical assessments and differential diagnosis of breast sarcoidosis.

Autopsy imaging for aspergillosis in King Penguin, an economically valuable zoo animal.

Autopsy imaging (Ai) was performed for a King Penguin. Ai-computed tomography (CT) revealed air sac membrane thickening, multiple nodules in the cranial air sac, suspected abscess, lung infiltration, and air sac contraction. Based on these findings, respiratory disorder was concerned. Aspergillosis, which is the highly observed in penguins, was considered as the primary differential diagnosis. The cultured sample showed characteristic conidial head of Aspergillus spp., the DNA of which was 100% identical to that of A. fumigatus. The cause of death was determined to respiratory failure due to aspergillosis. Ai-CT findings facilitated the dissection workflow and alerted the pathologist to potential hazards during the autopsy. Ai is useful to determine the cause of death and for readiness and safe pathological dissection.

Polyneuritis and Rare Sequelae of Leptospirosis Contracted While on an Urban Clean-Up Mission in Detroit : A Case Report of Weil’s Disease and Literature Review

Leptospirosis is a common zoonosis, an infectious disease that infects both humans and animals, which is caused by spirochete bacteria from genus Leptospira . Approximately 30% of children in urban Detroit and 16% of adults in Baltimore demonstrated serologic evidence of previous leptospirosis infections. The Detroit study showed correlation between degree of rat infestation and seropositivity rates. This finding suggests rats are major vectors for human leptospirosis in mainland United States. The leptospires from infected animals survive best in fresh water, damp alkaline soil, vegetation, and mud with temperatures higher than 22 °C. Although leptospirosis is a well documented clinical condition, the sequelae of polyneuritis has not yet been reported to our knowledge. The following case is an example of such an occurrence. A 49-year-old Caucasian female presented to the emergency department with flu-like symptoms after volunteering in an urban Detroit neighborhood clean-up project. She admitted to picking up wood from stagnant water without wearing personal protective equipment. The primary differential diagnosis being Weil’s disease from leptospirosis and was proven positive with serologic testing via the Center for Disease Control. A computed tomography (CT) abdomen and pelvis demonstrated lymphadenopathy throughout the abdomen and near the spinal column. She was treated with ceftriaxone and doxycycline for 12 days but developed chronic neuralgia and polyneuritis. Leptospires are known to cause vasculitis. This patient developed polyneuritis either from direct invasion of the nerves from leptospires or compromised blood supply to the nerves. In addition to antibiotics, patients with severe cases of leptospirosis also require supportive therapy and careful management of renal, hepatic, hematologic, and central nervous system complications. If renal failure ensues, early initiation of hemodialysis or peritoneal dialysis may reduce mortality. Rapid identification of symptoms and a high clinical suspicion are paramount because early intervention can save their life. J Med Cases. 2019;10(6):183-187 doi: https://doi.org/10.14740/jmc3320

Pancreatic Head Mass: A Rare Manifestation of Granulomatosis With Polyangiitis

A solid pancreatic mass is found to be malignant 95% of the time, while inflammation accounts for the remaining cases. We report a case of granulomatosis with polyangiitis (GPA) presenting as an inflammatory mass initially suspected to be metastatic pancreatic cancer. This is a 73-year-old male who presented to the ED with weakness, fevers, night sweats, and weight loss. His medical history was significant for severe chronic sinusitis and nasal polyps. On physical examination, he was noted to have bilateral lower extremity nodular purple plaques with necrotic centers. Laboratory studies were significant for leukocytosis, mildly elevated alkaline phosphatase, normal kidney function, transaminases and bilirubin. CT imaging demonstrated a low-attenuation mass in the pancreatic head along with multiple cavitary pulmonary nodules without hepatic lesions. Our differential diagnoses included metastatic pancreatic cancer versus an autoimmune process. CA 19-9 and CEA were within normal limits. An autoimmune work-up showed negative ANA, positive RF, elevated WSR, elevated IgE, and an elevated C-ANCA. Skin biopsy yielded leukocytoclastic vasculitis with granular fluorescence of C3 and IgG. Biopsy of lung nodules revealed extensive necrosis with acute neutrophilic infiltrates, fibrin thrombi, multinucleated giant cells, consistent with GPA. He was started on high dose steroids. He was discharged with plans for repeat imaging and biopsy of the pancreatic mass. A pancreatic mass in an elderly patient is highly concerning for cancer, which was our primary differential diagnosis. The absence of hepatic involvement and normal tumor markers decreased the likelihood of a primary pancreatic cancer with lung metastases. Due to his history of recurrent sinusitis, nasal polyps, and skin lesions, an autoimmune etiology was explored. A positive C-ANCA coupled with the lung biopsy findings established the diagnosis of GPA, a very rare cause of pancreatic masses. Most cases detailing GI manifestations of GPA present with pancreatitis or painless jaundice, but few have reported pancreatic masses. Necrotizing vasculidities can mimic pancreatic carcinoma and should be considered in the differential diagnosis of atypical cases. It is important to distinguish a pancreatic mass caused by GPA from pancreatic cancer due to the significant differences in treatment and prognosis. More studies are needed to determine whether these pancreatic masses should be biopsied or followed with imaging.1406_A.tif Figure 1: ßLungßonstrating extensive necrosis with acute neutrophilic infiltrates, fibrin thrombi, and multinucleated giant cells.1406_B.tif Figure 2: Low attenuation mass anteriorly in the pancreatic head measuring approximately 2.0 cm.

Clinical Application Value of Peripheral Blood Diagnostic Report

Objective: To explore the clinical application value of peripheral blood diagnostic report. Methods: 557 peripheral blood diagnostic reports were collected from Peking University First Hospital, YANDA LU DAOPEI Hospital and Beijing United Family Hospital. The results were analyzed and summarized according to different blood cell morphology character for the first time and review cases, respectively. Results: Two hundred and one samples from first time patients were found abnormal complete blood count or leukocyte differential count, they were summarized as anemia, anemia accompanied with leukopenia or thrombopenia, abnormal white blood cell count or leukocyte differential count and abnormal platelet count. Each condition was further distinguished on the basis of different morphology character. Initial diagnosis or further examination could be proposed if abnormal morphology was specific or typical, when blood cell morphology was atypical or normal, the morphology was described objectively. 22 review cases included many benign and malignant disorders such as acute leukemia, chronic leukemia, myelodysplastic syndrome, multiple myeloma, infectious mononucleosis and so on. Suggestion of therapeutic effect, progression of diseases or further examination could be present according to complete blood cell count and morphology character. Conclusion: Peripheral blood diagnostic report can provide more comprehensive and accurate information for clinic, and propose important advisory opinions for primary diagnosis, differential diagnosis, treatment monitoring and progression assessment.

Lead poisoning among opium users in Iran: an emerging health hazard

BackgroundLead (Pb) poisoning among people using opium has been an increasing problem in Iran. The present study highlights the clinical effects of lead toxicity associated with opium use in Iran, Kerman province.MethodsBetween January 2016 and June 2016, patients with signs and symptoms of Pb poisoning were questioned to assess whether they had a history of opium dependency. In total, 249 patients were enrolled onto this cross-sectional study, all were opium dependent. Para-clinical data including blood lead level (BLL), demographic information, user preferences, and symptoms were obtained.ResultsThe patients used either opium (83.9%), refined opium (6.4%) or a combination of both (9.7%) via ingestion (71.9%), smoking (8.4%) or a combination of both (19.7%). The overall median BLL was 80.0 μg/dL [IQR: 51.7–119.0]. The median BLL did not differ significantly between opium and refined opium users. Further, BLL was not significantly affected by the type of substance, route of use, duration of use, or daily quantity consumed. Common symptoms included abdominal pain (86.9%), constipation (75.8%), anorexia (71.5%) and nausea (54.7%). Linear regression analysis showed log of BLL was significantly associated with abdominal pain, myalgia and anorexia.ConclusionsThe study unravelled an increase in opium-related Pb poisoning in the Kerman province. Raised awareness of this emerging Pb source and investigation of its aetiology is recommended. Pb poisoning should be considered among the primary differential diagnosis of opium users with gastrointestinal symptoms.

Case report: A Rare Yet Life Threatening Mimicker of Chronic Conjunctivitis

Wegener’s granulomatosis (WG) is a necrotizing granulomatous inflammation. A 40-year-old lady of Malay descent presented with unresolving bilateral painful red eyes for three weeks. Clinical examination revealed that best corrected vision acuity of 6/9 for both eyes. Slit lamp examination revealed diffuse scleritis. Other Investigations result like UFEME blood cell: 2+, C-reactive protein 70.06 mg/L and ESR of 125mm/h suggestive on acute inflammations. Connective tissue screening revealed cytoplasmic ANCA was positive and was supported by Anti –Serine Protease3 (PR3) 68. All the investigations results revealed that she had Wegener’s granulomatosis with ophthalmology manifestation in the form scleritis. Patient was treated with guttae Maxidex QID to reduce cells that present in anterior chamber and oral ibuprofen 400mg thrice daily. Subsequently, commence oral prednisolone, oral cyclophosphamide with oral Bactrim. Patient responded well and redness resolved. There are many differential diagnosis for chronic conjunctivitis but to rule out connective tissue disease should be one of the primary differential diagnosis in young female. Oral immunosuppressive and Trimethoprim /Sufmethoxazole (Bactrim) has been found beneficial and symptoms were resolved . Wegener's granulomatosis is a great mimicker as exemplified in this case. This disease can be misdiagnosed and maltreated as conjunctivitis.Thus we wished to emphasize that WG is one the differential that need to be consider in a person with bilateral scleritis.Â
