Newly Diagnosed SLE With APLS and Right Atrial Thrombus.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disorder manifesting in myriad of forms and could affect almost any body system or organ. Antiphospholipid syndrome (APLS) is a relatively common scenario in SLE. Both arterial and venous thrombosis is a hallmark feature of APLS. Among others, intracardiac thrombus is a rare and potentially life-threatening presentation. It could occur in any heart chamber whereas the right atrium is the least common location. The treatment is based on anticoagulation preferably with warfarin along with treatment of SLE. We describe a young patient with newly diagnosed SLE with APLS complicated by right atrial thrombus formation. We are, therefore, adding to the scant literature on right atrial thrombi in SLE and increasing awareness of readers of this serious and potentially deadly condition if left unrecognized.

Treatment of Severe Swallowing Dysfunction in Systemic Sclerosis with IVIG: Role of Antimuscarinic Antibodies.

Oropharyngeal and esophageal dysmotility can cause serious clinical complications such as aspiration pneumonia, cachexia, and sarcopenia, with a resulting increase in mortality and disability. The current standard of care for the treatment of SSc-associated swallowing dysfunction is mainly supportive, although severe cases are usually refractory to conventional management. Recent studies have shown that the abnormal production of functional autoantibodies such as anti-cholinergic muscarinic receptor III antibodies may participate in the pathogenesis of SSc-associated gastrointestinal dysmotility and may provide a novel target for therapeutic intervention. We describe two patients with severe and rapid onset of SSc-associated severe swallowing dysfunction and esophageal dysmotility who had failed standard of care therapy, requiring complete enteral and parenteral nutrition. Both patients were positive for the presence of circulating antimuscarinic III receptor antibodies. They were treated with IVIG at a dose of 2 g/Kg/month divided in two consecutive days, for six months. Following IVIG therapy, both patients markedly improved their symptoms as shown by a reduction in their UCLA2.0 score, and achieved an improvement of esophageal motility documented radiologically. Both patients resumed oral feeding and had their feeding tubes removed within the treatment period. None of the patients developed severe adverse events attributable to IVIG, except for low-grade fever during IVIG infusion in one of the cases. These results provide support for the role of functional autoantibodies in the development of SSc-associated gastrointestinal dysfunction.

A 72-Year-Old Man With a Violaceous Rash and Sepsis.

CASE PRESENTATION: A 72-year-old man presented to our ED less than 24 hours following the acute onset of nausea, vomiting, and diarrhea. Within 12 hours of symptom onset, he noted bilateral lower extremity pain and swelling. His pain was associated with a new violaceous irregular rash on the anterior aspect of both feet and legs. There was no history of inciting trauma or recent wounds. In addition, there was no history of consumption of raw or undercooked food (including seafood) or recent change in food source. There was accompanying fever and chills for the same duration and painful swelling of his left thumb. His comorbidities included stage IIIb classical Hodgkin lymphoma diagnosed 4 months prior. His last dose of doxorubicin, bleomycin, vinblastine, and dacarbazine chemotherapy was 4 days before presentation. He had previously failed anti-CD30 monoclonal therapy resulting from attributed pancolitis.

Emphysematous osteomyelitis of the forefoot.

Emphysematous osteomyelitis is a very rare, potentially fatal infection that requires immediate diagnosis and prompt treatment. Emphysematous osteomyelitis is usually considered whenever intraosseous gas is detected on imaging. Most organisms implicated in emphysematous osteomyelitis are members of the Enterobacteriaceae family or anaerobes; sometimes the infection is polymicrobial. We report a case of emphysematous osteomyelitis of the forefoot in a 33-year-old man with type 1 diabetes mellitus.

Idiopathic Giant Hepatic Artery Pseudoaneurysm.

Hepatic artery pseudoaneurysm (HAP) incidence is rising due to more common use of endoscopic and percutaneous hepatic interventions. HAP is potentially fatal, as it could lead to sudden life-threatening hemorrhage. HAP can be intrahepatic or extrahepatic. On computed tomography angiogram (CTA) and magnetic resonance angiogram (MRA), HAP follows blood pool on multiphasic examination, with brisk arterial enhancement that washes out, similar to the abdominal aorta on later phases. We present a case of idiopathic giant HAP in an 82-year-old male. Currently, angioembolization is replacing surgery as the initial modality of choice for management of this condition.

Acute Calcific Tendinitis of the Longus Colli Muscle: Report of Two Cases and Review of the Literature.

Acute calcific tendinitis (ACT) of the longus colli muscle is a rare cause of debilitating neck pain. The ACT is presumed to be an aseptic inflammatory process of the superior oblique tendons of the longus colli muscle. It is often confused with other more concerning conditions including trauma, epidural abscess, disc herniation, and neoplasm. We present two cases of ACT and a brief literature review to stress the risk of misdiagnosis. A 38-year-old male presented with neck pain and stiffness accompanied by dysphagia. Computed tomography (CT) scan was done and the diagnosis was secured by demonstrating calcifications at the C1-C2 level as well as the retropharyngeal effusion. A 53-year-old female was also complaining of neck pain and dysphagia. The CT scan demonstrated similar findings and the diagnosis was again clinched. Awareness of this unusual entity is essential to prevent unnecessary interventions.
