Mottling sign

Juvenile dermatomyositis (JDM) is a chronic autoimmune inflammatory disorder and is considered the most common form of idiopathic inflammatory myopathies. JDM primarily affects the skin and the skeletal muscles. Characteristic signs and symptoms include Gottron papules, heliotrope rash, calcinosis cutis, and symmetrical proximal muscle weakness. However, JDM presenting with generalized scaly poikeloderma is an unfamiliar presentation. Herein we report a 14-month-old female toddler presented with generalized progressive asymptomatic scaly mottled violaceous patches (poikilodermatous) that started when she was seven months old...

OBJECTIVES: The aim of this study was to describe the abdominal ultrasonographic findings in cats with confirmed or presumed feline infectious peritonitis (FIP). METHODS: This was a retrospective study performed in an academic veterinary hospital. The diagnosis of FIP was reached on review of history, signalment, clinical presentation, complete blood count, biochemistry panel, peritoneal fluid analysis, cytology and/or histopathology results from abnormal organs, and/or molecular testing (immunohistochemical or FIP coronavirus [FCoV] RT-PCR)...

The golden jackal (Canis aureus) is a reoccurring species in the centre of the Carpathian basin, in Hungary. In total, 31 golden jackal tissue samples were collected, from 8 white-coated, 2 black-coated and one mottled animal across Hungary. Sequences and fragment length polymorphisms were studied for white colour (MC1R), and for black coat colouration (CBD103). In each white animal, the most widespread mutation causing white fur colour in dogs in homozygous form was detected. Three animals were found to carry the mutation in heterozygous form...

BACKGROUND: Skin mottling as a clinical perfusion marker in septic shock is significantly associated with severity and outcome in white-skinned population and its validity as a clinical sign in dark-skinned population is not known. The objectives of this study were to evaluate mottling in septic shock in the Indian ethnic population who has different skin color as compared to the white-skinned population and to assess mottling as an outcome predictor with capillary refill time (CRT) and other biochemical parameters which are the established clinical markers of perfusion in septic shock...

Actinic keratosis (AK), due to its widespread prevalence, as well as the possibility of progression to an invasive form of squamous cell carcinoma, requires treatment regardless of the clinical stage. New imaging techniques, such as in vivo reflectance confocal microscopy (RCM), significantly increase the accuracy of diagnosis and allow noninvasive evaluation of the therapeutic efficacy of the ongoing treatment. Our objective was to evaluate the prevalence of specific (video)dermoscopy and RCM features of pigmented and classical subtypes of AK before and after photodynamic therapy (PDT) treatment...

The recently detected clade 2.3.4.4 of the highly pathogenic avian influenza (HPAI) H5N8 virus in poultry encouraged us to study the efficacy of the 6 most extensively used saleable H5 poultry vaccinations (bivalent [AI + ND], Re-5 H5N1, H5N1, H5N3, monovalent AI, monovalent ND) with or without aqueous 8% neem (Azadirachta indica) leaf extract as an immunostimulant. One hundred thirty birds were randomly divided into 7 groups. Groups 1, 2, 3, 4, 5, and 6 were divided into 2 subgroups (G1a, G2a, G3a, G4a, G5a, G6a) and (G1b, G2b, G3b, G4b, G5b, G6b) with 10 birds each...

OBJECTIVE: Diagnosis of acute myocarditis or dilated cardiomyopathy (DCM) on initial presentation is difficult in children younger than 2 years because most present with complaints suggestive of a respiratory infection. The objective of this study is to determine whether signs, symptoms, and diagnostic studies excluding those of heart failure, done routinely in the emergency department could distinguish children younger than 2 years with acute myocarditis or DCM from those with respiratory illnesses...

RATIONALE: The diagnosis of mesenteric ischemia in critically ill patients remains challenging; however, the aquarium sign, comprising a large number of bubble images in the right cardiac chambers on echocardiography, may be used as a point-of-care ultrasound finding to diagnose acute mesenteric ischemia (AMI). PATIENT CONCERNS: A 65-year-old woman diagnosed with lymphoma was urgently admitted to the intensive care unit with suspected tumor lysis syndrome. High-dose vasopressor and inotropic agents were required to manage the patient's shock with marked lactic acidosis and peripheral hypoperfusion with mottled skin, and multidisciplinary treatment was initiated...

BACKGROUND: Langerhan cell histiocytosis (LCH), although not a common cause, should be kept in the differential diagnosis for a patient that presents with a choroidal mass. CASE PRESENTATION: A 28-year-old female presented with a 4-day history of vision loss and associated pain in her right eye. EXAMINATION AND INVESTIGATIONS: A dilated fundus examination revealed a deep subretinal, orange, mottled lesion with associated serous retinal detachment...

An outbreak of morbidity and mortality in an African dwarf frog ( Hymenochirus curtipes) colony was reported following arrival at an animal research facility. Animals were found dead on arrival or became moribund shortly thereafter, and additional animals showed clinical signs of lethargy, weight loss, and anorexia over the following 3 weeks. Externally, some affected animals presented with multifocal areas of hyperemia in the inguinal and axillary areas and on the limbs, and mottled tan discoloration along the ventral abdomen...

This report characterizes the first lethal outbreak of Marek's disease on a large farm of mixed-breed adult ducks (>18,000) and identifies the pathogen that resulted in high mortality (35%). Clinical signs included inappetence, respiratory distress, depression, muscle weakness, and ataxia. Post mortem revealed enlarged fragile liver mottled with miliary whitish spots and an enlarged spleen. Histopathology revealed hepatocellular necrosis with eosinophilic intra-nuclear inclusion bodies, necrosis of splenic follicles and degeneration/necrosis of renal tubules...

A five-month-old, 3.8 kg intact male Maine coon cat presented for dyspnea characterized by increased respiratory effort in addition to open-mouth breathing. Thoracic radiographs showed pectus excavatum, enlarged cardiac silhouette, and generalized interstitial patterns. Echocardiography revealed normal left atrial (LA) and left ventricular dimensions. A large tubular structure, suspected to be a distended pulmonary vein (PV), was identified as draining into the LA. Severe eccentric and concentric right ventricular hypertrophy and paradoxical septal motion were noted...

BACKGROUND: The livestock sector contributes 1.90% to the GDP in Bangladesh during 2021-22. Poultry is one of the important subsectors struggling with diseases. Fowl adenoviruses (FAdVs) cause numerous diseases resulting in economic losses to the poultry industry worldwide. Several FAdV serotypes cause inclusion body hepatitis in chicken. Although FAdV infection was suspected, there was no confirmatory report from Bangladesh. The study was conducted to investigate the FAdV infection and antibodies in chicken...

Skin aging is induced and sustained by chronological aging and photoaging. Aging skin pigmentation such as mottled pigmentation (senile lentigo) and melasma are typical signs of photoaging. The skin, like other human organs, undergoes cellular senescence, and senescent cells in the skin increase with age. The crosstalk between melanocytes as pigmentary cells and other adjacent types of aged skin cells such as senescent fibroblasts play a role in skin-aging pigmentation. In this review, we provide an overview of cellular senescence during the skin-aging process...

Rationale: Identification of cardiogenic shock severity is a critical step to adapt the management level upon admission. Peripheral tissue perfusion signs, simple and reliable markers of tissue hypoperfusion have never been extensively assessed during cardiogenic shock. Objectives: To assess the correlation of capillary refill time values with 90-day mortality in cardiogenic shock patients or the need for venoarterial extracorporeal membrane oxygenation (VA-ECMO) support. Also to assess the correlation between capillary refill time and hemodynamic parameters...

Evaluation of hematuria and microscopic examination of urine sediment are commonly used tools by nephrologists in their assessment of glomerular diseases. Certain morphological aspects of urine red blood cells (RBCs) seen by microscopy may help in identifying the source of hematuria as glomerular or not. Recognized signs of glomerular injury are RBC casts or dysmorphic RBCs, in particular acanthocytes (ring-shaped RBCs with protruding blebs). Despite being a highly operator-dependent test, urine sediment examination revealing these signs of glomerular hematuria has demonstrated specificities and positive predictive values ranging between 90%-100% for diagnosing glomerular disease, although sensitivity can be quite variable...

OBJECTIVE: To evaluate the clinical effects of acupoint catgut embedding combined with quadruple therapy on Helicobacter pylori (Hp)-positive (+) chronic atrophic gastritis (CAG) of spleen and stomach deficiency syndrome and explore the underlying mechanism. METHODS: Hp (+) CAG patients with spleen and stomach deficiency syndrome were randomly divi-ded into a control group ( n =68) and a treatment group ( n =71). In addition to the routine quadruple therapy for two weeks, the patients in the control group received oral Weifuchun Tablets (4 tablets once, tid...

BACKGROUND: Acute thrombosis of an abdominal aortic aneurysm with acute limb ischaemia is an unusual complication and is associated with high mortality. Dislocation of the intrasaccular mural thrombus could be one of the mechanisms. For the most part, acute limb ischaemia presents with absent pulses, compatible with the clinical findings, which include pain, paraesthesia, and paralysis. Herein, we report a rare condition with detectable distal pulses in advanced limb ischaemia due to poor perfusion caused by the dislocation of mural thrombus from an abdominal aortic aneurysm...

Pascalia glauca, a perennial herb known for its toxicity in ruminants, is one of the most important toxic plants in northwestern Argentina. This work describes several outbreaks of natural intoxication with P. glauca from different sources affecting cattle, sheep and goats in different production systems, with morbidity varying between 1% and 100%. Clinical signs included tremors in the hindquarters, recumbency and death. The liver showed swelling, congestion and a mottled appearance. Histopathologic findings included centrilobular hepatocellular necrosis with hemorrhage...

Obstructive shock describes any disease process that causes physical obstruction to blood flow into or out of the heart which results in impaired systemic oxygen or nutrient delivery. Common etiologies include cardiac tamponade, tension pneumothorax, and pulmonary embolus. However, several other causes exist and should prompt consideration in the correct clinical circumstances. In this report, we describe a 72-year-old female patient with history of hepatic cysts presenting with respiratory distress, mottled extremities, and abnormal vital signs...
