Idiopathic Myelofibrosis is a rare myeloproliferative disorder. In children, it becomes even rarer. Herein, we report a case of idiopathic myelofibrosis of a 6-year old male patient who presented with complaints of pallor, petechiae and bleeding from gums. Bone marrow aspirate showed afragmented haemodiluted smears with erythroid and myeloid precursors scattered throughout. Trephine biopsy showed increased background fibrotic activity along with clusters of histiocytes. A diagnosis of paediatric primary myelofibrosis was made on biopsy...

REVIEW
Abraham M Korman, Ali Alikhan, Benjamin H Kaffenberger
Although classic viral exanthems of childhood are well described, they are rarely differentiated in adults. Laboratory techniques for viral identification have advanced without substantial literature to suggest how a dermatologist ought to conduct a cost-effective and diagnostic viral panel. Certain clinical features such as petechiae, vesicles, and dusky macular or morbilliform exanthems point strongly toward a viral exanthem. Differentiation of drug and viral causes of morbilliform eruptions has proven difficult...

Imatinib mesylate (imatinib) is a tyrosine kinase inhibitor initially approved by the US Food and Drug Administration in 2001 for chronic myeloid leukemia (CML). Since then, the number of indicated uses for imatinib has substantially increased. It is increasingly important that dermatologists recognize adverse cutaneous manifestations of imatinib and are aware of their management and outcomes to avoid unnecessarily discontinuing a potentially lifesaving medication. Adverse cutaneous manifestations in response to imat-inib are not infrequent and can include dry skin, alopecia, facial edema, and photosensitivity rash...

BACKGROUND: Palatal petechiae are 95% specific for streptococcal pharyngitis. Despite this, and despite prior research demonstrating that Group A Streptococcus (GAS) is a common antecedent to pediatric acute-onset neuropsychiatric syndrome (PANS) episodes, we anecdotally observed a low rate of documented GAS in patients with PANS and palatal petechiae. This retrospective chart review was conducted to formally report the rate of palatal petechiae and concurrent GAS in a cohort of patients with PANS and investigate other etiologic factors...

The patient was nauseous, and had been experiencing headaches, generalized weakness, and fatigue. Her physical exam revealed a maculopapular rash on her trunk and upper extremities. She had tenderness and pain, as well as decreased range of motion in her ankles, knees, and wrists. The patient had no erythema, swelling, petechiae, or bruising. She had a past medical history of Graves' disease and had received all of her childhood immunizations.

Early identification of non-accidental trauma (NAT) is a critical component of pediatric trauma care. Literature searches were conducted related to the association of NAT with seven key areas: history, exam findings (burns, oral trauma, bruising) and imaging (fractures, abdominal and brain injuries). When available, odds ratios (OR) with 95% confidence intervals (CI) for associations with NAT are presented. Systematic reviews have been published in six of the seven key areas and are described. The operational definition of NAT was widely variable across studies, prohibiting meta-analysis...

BACKGROUND: Sexually transmitted infections, includingurogenital gonorrheal infection, are a growing healthconcern in the United States. Nearly 50% of cervicalinfections are asymptomatic. If left undiagnosedand untreated, there is a risk of disseminatedinfection. PURPOSE: To describe an 18-year-old womanpresenting with disseminated gonococcal infectionconfirmed by blood cultures, skin biopsy, and urinegonococcal probe. We also describe the presentation,diagnosis, and treatment of disseminated gonococcalinfection, including discussion of the variousmorphologies of cutaneous lesions that have beenreported in the literature...

Adrenal histologic changes, including compact cell change (CCC), cystic change (CYC), and adrenal hemorrhage (AH), and their clinical correlations have only infrequently been investigated in stillbirth. We evaluated 75 third trimester singleton stillborns with complete autopsies (30 term and 45 preterm). A total of 58 had unexplained stillbirth and 17 had clinical placental abruption. The mothers were predominantly African-American (89%). CCC and CYC were diagnosed as cytoplasmic eosinophilia and cystic cavities in the definitive cortex, respectively...

Case 1: A 78-year-old woman was diagnosed with H. pylori positive gastritis at a previous hospital in April 2012 and received 3rd-line H. pylori eradication therapy, which ended in failure. She was referred to our department due to oral hemorrhage, petechiae involving all four extremities, and thrombocytopenia in January 2016. She was hospitalized with a diagnosis of ITP and received inpatient treatment. While receiving outpatient prednisolone (PSL) treatment, we administered 4th-line eradication therapy in March...

Chromobacterium violaceum is an opportunistic pathogen of mammals that produces characteristic violet pigment in bacterial culture. We report pneumonia and septicaemia caused by C. violaceum in a horse. Necropsy examination was performed on a 3-year-old Quarter Horse stallion with a history of recurrent episodes of pneumonia, fever, dyspnoea and sanguineous nasal discharge. The lungs were not collapsed, but they contained dark red foci mixed with white areas, and multiple nodules of firm consistency. Within the liver and kidney there were randomly distributed, multifocal, white pinpoint lesions (0...

Children often present to emergency departments (EDs) with uncontrollable nose bleeding. Although usually due to benign etiologies, epistaxis may be the presenting symptom of an inherited bleeding disorder. Whereas most bleeding disorders are detected through standard hematologic assessments, diagnosing rare platelet function disorders may be challenging. Here we present two case reports and review diagnostic and management challenges of platelet function disorders with a focus on Glanzmann's thrombasthenia (GT)...

Immune thrombocytopenia (ITP) is an auto-immune condition that results in isolated thrombocytopenia associated with possibly lethal haemorrhage. In its secondary form, ITP can be triggered by many infectious and non-infectious conditions. Secondary ITP associated with tuberculosis (TB) has rarely been described in the literature. We report on a 22-year-old patient presenting with hypermenorrhoea and petechiae due to ITP secondary to tuberculous lymphadenitis. Normalisation of thrombocytopenia was only achieved after initiation of anti-tuberculosis treatment following failure of thrombocyte substitution and immune-modulatory treatment...

BACKGROUND: Dengue is the commonest vector-borne infection worldwide. It is often associated with thrombocytopenia, and prophylactic platelet transfusion is widely used despite the dearth of robust evidence. We aimed to assess the efficacy and safety of prophylactic platelet transfusion in the prevention of bleeding in adults with dengue and thrombocytopenia. METHODS: We did an open-label, randomised, superiority trial in five hospitals in Singapore and Malaysia...

BACKGROUND: Immune checkpoint inhibitors, including antibodies against programmed death 1 (PD-1) and cytotoxic T-lymphocyte antigen 4 (CTLA-4), are being used with increasing frequency for the treatment of cancer. Immune-related adverse events (irAEs) including colitis, dermatitis, and pneumonitis are well described, but less frequent events are now emerging with larger numbers of patients treated. Herein we describe the incidence and spectrum of thrombocytopenia following immune checkpoint inhibitor therapy and two severe cases of idiopathic thrombocytopenic purpura (ITP)...

RATIONALE: Disseminated intravascular coagulation (DIC) induced by daily rifampicin therapy is rare, especially the patient is absent of malignancy, severe infection, and prior exposure to rifampicin. PATIENT CONCERNS: We report a case of DIC induced by daily rifampicin treatment for pulmonary tuberculosis. A 22-year-old, previously healthy man received an anti-tuberculosis therapy consisting of isoniazid, rifampicin, ethambutol, and pyrazinamide on the daily dose recommended by the World Health Organization tuberculosis guidelines after a diagnosis of pulmonary tuberculosis...

Wood frogs ( Rana sylvatica) are highly susceptible to infection with Frog virus 3 (FV3, Ranavirus, Iridoviridae), a cause of mass mortality in wild populations. To elucidate the pathogenesis of FV3 infection in wood frogs, 40 wild-caught adults were acclimated to captivity, inoculated orally with a fatal dose of 10(4.43) pfu/frog, and euthanized at 0.25, 0.5, 1, 2, 4, 9, and 14 days postinfection (dpi). Mild lesions occurred sporadically in the skin (petechiae) and bone marrow (necrosis) during the first 2 dpi...
