Inflammatory myopathies and lymphoma

The inflammatory myopathies comprise a group of immune-mediated muscle diseases. Lymphoma is a term for a variety of lymphatic system malignancies. Autoimmune diseases and lymphoproliferative malignancies share a complex bidirectional relationship. A causal relationship between inflammatory mypathies and lymphoma has not been established. The diagnosis/treatment of inflammatory myopathy usually precedes the detection/diagnosis of lymphoma. Immune system dysregulation presumably underlies the evolution of lymphoma in patients with inflammatory myopathies. Inflammatory activity with chronic B-cell activation and/or antigen stimulation is deemed the major risk factor for lymphoma in patients with autoimmunity. A "paraneoplastic" phenomenon or the effects of immunosuppressive therapy may be alternative immune-based mechanisms. In chronic lymphocytic leukemia immune system disturbance rarely results in non-hematological autoimmune disease, including inflammatory myopathies.

Periorbital edema: a puzzle no more?

PURPOSE OF REVIEW

Periorbital edema is a common problem that deserves scrutiny. Although a variety of healthcare providers may see this clinical entity, ophthalmologists are often consulted along the way toward diagnosis. It can challenge even the most astute clinicians. A diagnosis may reveal merely a bothersome issue or potentially a sight-threatening or life-threatening problem.

RECENT FINDINGS

Comprehensive reviews on this topic are scarce. Textbooks are brief. There are, however, many studies in the scientific literature of notable cases of periorbital edema. The causes generally fall into the categories of infectious, inflammatory or tumors, medication related, and postsurgical or trauma.

SUMMARY

This article synthesizes the current literature on the topic with a case series from our institution. It aims to provide a thorough resource for all practitioners to make the prospect of triaging, diagnosing, and treating periorbital edema less daunting.

Hematological malignancy associated with polymyositis and dermatomyositis

The aims of this present study were to: 1) assess the characteristics of hematological malignancies in polymyositis/polymyositis (PM/DM) patients; and 2) determine predictive variables of hematological malignancies in PM/DM patients. We retrospectively reviewed the medical records of 32 patients (14 PM, 18 DM) associated with hematological malignancies. In our 32 PM/DM patients, hematological malignancy was concurrently identified (18.8%) or occurred during the course of PM/DM (31.2%); although, PM/DM more often preceded hematological malignancy onset (50%). We observed that the types of hematological malignancies varied, consisting of: B-cell lymphoma (n=20), T-cell lymphoma (n=4), Hodgkin's disease (n=2), multiple myeloma (n=1), myelodysplastic syndrome without excess of blasts (n=3), hairy cell (n=1) and acute lymphocytic leukemia (n=1). In 21 patients of our 32 patients with PM/DM-associated hematological malignancy (65.6% of cases), PM/DM paralleled the course of hematological malignancy. Finally, we observed that patients with PM/DM-associated hematological malignancies had a poor prognosis, the survival status ranging from 96.9%, 78.1% and 51.4% at 1, 3 and 5years, respectively. Interestingly, we found that patients with hematological malignancies, compared with those without were older and more frequently had DM; on the other hand, these patients less commonly exhibited: joint involvement (p=0.017), interstitial lung disease (p=0.06) and anti-Jo1 antibody (p=0.001). Taken together, our study underscores that the association between PM/DM and hematological malignancy, especially lymphoma, should not be ignored. Our findings also suggest that antisynthetase syndrome may be a protective factor of hematological malignancy in PM/DM patients.

Fever and Periorbital Edema: A Review

Fever and periorbital swelling are the manifestation of a broad array of diseases. Among them are emergency situations, which need prompt physician input. Swiftly formulating a differential diagnosis approach is crucial. Diseases causing fever and periorbital edema are either local or systemic. Nevertheless, their impact can be systemic if they evade diagnosis. Infectious diseases and non-infectious diseases (inflammatory and allergic diseases, autoimmune diseases, neoplastic diseases, and trauma) can all lead to fever and periorbital edema. A meticulous history and physical examination in association with targeted tests against the presented spectrum of diseases (specific serological tests, radiological tests, cultures taken from the surface of the periorbital area and other relevant areas, and skin biopsy for histological and microbiological examination) will clarify the diagnosis.
