Abstract Background Talaromyces Marneffei (Penicillium marneffei, T.marneffei) has been frequently reported in patients with adult acquired immunodeficiency syndrome. Still, cases of children with HIV combined with T.marneffei infection are very rare. This report describes the case of a HIV-child who is a girl from China. Her special clinical manifestations and laboratory diagnosis results can provide clinicians with the basis for diagnosis and treatment of T.marneffei related rare diseases. Case presntation We reported a single case of 7-year-old Chinese female patient who presented with fever, abdominal pain, multiple lymphadenopathy, hepatosplenomegaly, left lower extremity ecchymosis, and bloody stool. The patient received anti-inflammatory therapy; however, her symptoms did not improve. Consequently, she was diagnosed with T.marneffei and HIV infection; it was also confirmed that her mother did not undergo HIV blocking therapy during pregnancy. Yet, the child’s family refused all treatment, after which the child was discharged from the hospital. The patient died a few days later. Conclusion This case suggested that children with AIDS suffering from fever, lymphadenopathy and coagulation dysfunction, penicilliosis should be suspected. Clinicians should diagnose the disease early through laboratory and imaging results, which can help reduce the mortality, prolong the survival time and improve the quality of life of children.

We describe the case of an 18-year-old male Army reservist presenting with left lower extremity pain for which he was initially diagnosed with a stress injury. After failing conservative treatment, a radiograph was obtained showing a "lacelike" appearance of the medullary bone in the foot and ankle. Magnetic resonance imaging subsequently demonstrated widespread polyostotic marrow replacement with coarsened trabeculations. A biopsy was obtained which diagnosed the patient with polyostotic epithelioid hemangioendothelioma which is the most common malignant vascular tumor of bone. The patient ultimately underwent a below the knee amputation once computed tomography of the chest, abdomen, and pelvis excluded distant metastatic disease. It is important for radiologists to be aware of this diagnosis because osseous epithelioid hemangioendothelioma can present like a stress injury and be mistaken for a less serious diagnosis while potentially having visceral involvement.

An 84-year-old male patient with no known comorbidity was admitted to the emergency department with complaints of dyspnea and respiratory distress. The patient was referred to the COVID outpatient clinic, laboratory and radiology tests were performed. Thoracic CT scan of the patient showed large peripheral patchy ground glass densities observed in the lower lobes of both lungs. CT imaging findings were evaluated by an experienced radiologist and reported as COVID-19 pneumonia. The patient, who was self-isolated at home for 5 days, presented to the emergency department again on the fifth day with complaints of respiratory distress, fever, bruising with cough, and loss of peripheral pulse in the left lower extremity. Necessary tests were performed on the patient. An above-knee amputation was performed when a diagnosis of limb ischemic necrosis was made and no revascularization attempt was considered by the CVS department. This case study describes the coexistence of sudden lower extremity thrombosis and Covid-19 in our case without a known chronic disease.

Abstract Background COVID-19 and Fontan physiology have each been associated with an elevated risk of venous thromboembolism (VTE), however little is known about the risks and potential consequences of having both. Case presentation A 51 year old male with tricuspid atresia status post Fontan and extracardiac Glenn shunt, atrial flutter, and sinus sick syndrome presented with phlegmasia cerulea dolens (PCD) of the left lower extremity in spite of supratherapeutic INR in the context of symptomatic COVID-10 pneumonia. He was treated with single session, catheter directed mechanical thrombectomy that was well-tolerated. Conclusions This report of acute PCD despite therapeutic anticoagulation with a Vitamin K antagonist, managed with emergent mechanical thrombectomy, calls to attention the importance of altered flow dynamics in COVID positive patients with Fontan circulation that may compound these independent risk factors for developing deep venous thrombosis with the potential for even higher morbidity.

Abstract Background Immune-mediated necrotizing myopathy (IMNM) is characterized by proximal muscle weakness, elvated serum muscle enzyme levels, myopathic electromyography findings, and necrotic muscle fiber with few inflammatory cell infiltration in muscle biopsies. Statins, the first line drug to lower triglyceride and cholesterol level in blood, have been reported to be associated with statins-induced necrotizing autoimmune myopathy (SINAM). Although anti-3-hydroxy-3-methylglutarylcoenzyme-A reductase (anti-HMGCR) myopathy is considered as the leading myopathy related to the statins medication, anti-signal recognition particle (SRP) myopathy were also identified in several cases with statin exposure. The risk of deep venous thrombosis (DVT) is substantially high in individuals with autoimmune inflammatory diseases. But few studies have reported the occurrence and recommendation for treatment of DVT in patients with anti-SRP myopathy. Here, we reported a statin-exposed anti-SRP myopathy individual developed DVT who was successfully treated with catheter-directed thrombolysis (CDT) and systemic anticoagulants therapy. Case presentation A 56-year-old Chinese female came to the outpatient room with gradually progressive bilateral lower-extremity weakness. Magnetic resonance imaging revealed myopathy in bilateral thighs. Serum anti-SRP antibody was positive. She was diagnosed with anti-SRP myopathy. When treated with corticosteroids and immunosuppressants, the patient developed mild edema and pain of left lower extremity. Angiography and ultrasound revealed diffuse venous thrombosis of left lower extremity. Therapy was initiated with CDT and lower molecular weight heparin, then switched to once daily oral rivaroxaban. Meanwhile, steroids combined with tacrolimus were also carried on while simvastatin was discontinued. One month later, patient’s symptoms were resolved and only partial thrombosis in left femoral vein was remained. Conclusion The prevalence of DVT in patient with anti-SRP myopathy was rare. No well-established treatment strategy is available to manage the IMNM and DVT at the same time. The systemic anticoagulants therapy combined CDT can be an effective therapeutic approach to address extensive DVT in patient with anti-SRP myopathy.

The question arises whether footedness transforms into asymmetrical incidence of wear and tear within lower extremity joints. After obtaining institutional review board approval for exempt research, the author manually counted the number of patients who underwent right or left or bilateral, hip or knee, primary or revision arthroplasty over a five-year period (2016-2020) at a university-affiliated hospital in the United States. Overall, right lower extremity arthroplasty was significantly commoner than left lower extremity arthroplasty (P=0.002). Individually, only right primary hip arthroplasty (P=0.033) and right revision knee arthroplasty (P=0.041) were significantly commoner procedures than their left counterparts. These results should set up the stage for future investigations into footedness retrospectively and prospectively to rule out if commoner right footedness in itself is driving this asymmetrical incidence of lower extremity arthroplasty or whether automatic transmission vehicular driving is independently contributing to this asymmetrical incidence.

Acute limb ischemia (ALI) is rarely observed in young populations. The hypercoagulable state is a notable cause of ALI other than artery disease progression and cardiac embolization. A hypercoagulable state occurs in essential thrombocytosis because of the overproduction of hematopoietic cells secondary to the mutation of the JAK2, CALR, or MPL genes. We report a rare case of a 37-year-old woman presenting with Rutherford IIA ALI in the left lower extremity. Laboratory data revealed she had a platelet count reaching up to 1.38 mil/μL, with other blood profiles being normal. A JAK2 mutation examination was later performed and proved positive. After careful management with catheter-directed thrombolysis, surgical thrombectomy, and cytoreductive therapy using hydroxyurea, the symptoms subsided and eventually restored the patient to physical activity in less than one month.

Abstract Objective To report a de novo splicing mutation in the CSF1R gene in a patient with hereditary diffuse leukoencephalopathy with spheroids (HDLS). Methods A 42-year-old Chinese woman with constant weakness on her left lower extremity was recruited in the current study. Detail medical history and clinical characteristics were reviewed. Brain magnetic resonance imaging (MRI), whole-exome sequencing, and Sanger sequencing were performed with bioinformatics analysis. Results The Chinese HDLS patient with no HDLS family history exhibited a de novo splicing mutation (c.1754-10 T > A) in the CSF1R gene. This mutation was located at the splice site of intron 12 and resulted in the skipping of exon 13 from the CSF1R mRNA. This finding constitutes the first de novo splicing mutation ever reported in HDLS. Furthermore, MRI abnormalities had been reported at least 6 months prior to the onset of the patient’s clinical phenotype. Conclusion Our study indicates that the diagnosis of HDLS should be considered even in the absence of a family history and can help deepen the clinical and genetic understanding of HDLS.

Immune-mediated necrotizing myopathy, a new subgroup of inflammatory myopathies, usually begins with subacute onset of symmetrical proximal muscle weakness. A 35-year-old male presented with severe asymmetric iliopsoas atrophy and low back pain with a previous history of left lower extremity weakness. Although his first left lower extremity weakness occurred 12 years ago, he did not receive a clear diagnosis. Magnetic resonance imaging of both thigh muscles showed muscle edema and contrast enhancement in patch patterns, and the left buttock and thigh muscles were more atrophied compared to the right side. Serum creatine kinase levels were elevated, and serologic testings were all negative. Genetic testing using a targeted gene-sequencing panel for neuromuscular disease including myopathy identified no pathogenic variants. Muscle biopsy on the right vastus lateralis showed scattered myofiber necrosis with phagocytosis and an absence of prominent inflammatory cells, consistent with seronegative necrotizing myopathy. Thus, unusual asymmetric muscle weakness and atrophy can be a manifestation of inflammatory myopathy.

Abstract Introduction: Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) syndrome is a rare drug hypersensitivity reaction characterized by diffuse skin eruption with systemic symptoms (fever, lymphadenopathy, elevated transaminases, leukocytosis with eosinophilia and atypical lymphocytes) which develops 2-6 weeks after exposure to inciting medications. Clinical presentation is variable and nonspecific. DRESS syndrome is more common in adults, can be life threatening, and is most commonly seen with antibiotics, antiepileptic drugs, and allopurinol. An inciting drug is identified in the majority of cases. DRESS syndrome has been described rarely in association with Vitamin K antagonists and direct oral anticoagulants. In an in-depth examination of existing literature, there are only two reported cases of DRESS syndrome associated with enoxaparin therapy, both in adult patients and no reports of pediatric DRESS syndrome secondary to anticoagulants. We present a case of a pediatric patient with DRESS syndrome associated with enoxaparin therapy. Case Report: A previously healthy 11-year-old female was admitted with sepsis secondary to osteomyelitis and periosteal abscess of the left lower extremity, as well as MRSA bacteremia. The patient was initiated on clindamycin and vancomycin for treatment of underlying infections. A left lower extremity ultrasound with doppler was obtained due to lower extremity swelling and demonstrated an acute deep venous thrombus of the left popliteal vein. She was initiated on a heparin drip and subsequently transitioned to enoxaparin one week later. Several weeks into her hospital course (two weeks after initiation of enoxaparin), she developed facial swelling, a generalized morbilliform rash, and diffuse lymphadenopathy both on exam and abdominal imaging. She continued to have persistent fevers despite multiple washouts of the extremity, appropriate antimicrobial coverage, and negative blood cultures. Liver enzymes concurrently increased (AST 362 IU/L (normal 5-60 IU/L), ALT 371IU/L (normal <35 IU/L) at peak) with development of clinical symptoms. Eosinophilia was not present on initial CBC, though she subsequently developed mild eosinophilia (1.1 K/ul at peak). HHV6, CMV, and EBV serologies were all negative. Skin biopsy was performed and was consistent with a drug eruption. Using the RegiSCAR criteria for DRESS syndrome, this constellation of labs and symptoms indicate a definite case of DRESS syndrome with a score of 6 (final score >5 is needed for a definite case). The patient was started on treatment with high-dose steroids. Clindamycin and vancomycin were both discontinued due to their known association with DRESS syndrome. She was transitioned to doxycycline, however, no improvement in rash, fevers, or liver enzymes was seen over the course of five days. Given this, enoxaparin was transitioned to apixaban. The patient improved with resolution of rash, fevers, and improvement of liver enzymes and eosinophilia within a few days of the discontinuation of enoxaparin. Conclusion: The diagnosis of DRESS syndrome can be challenging due to its nonspecific presentation, particularly in pediatric patients where symptoms can overlap with common viral syndromes and Kawasaki disease, and therefore requires a high index of suspicion. Though children with DRESS syndrome have a better prognosis than adults, prompt recognition and treatment is required to limit morbidity and mortality. In pediatric patients receiving treatment with enoxaparin, DRESS syndrome should be included on the differential for those who develop persistent fevers, lymphadenopathy, rash, transaminitis and/or eosinophilia, and discontinuation of enoxaparin should be considered.
