Cardiac manifestations in systemic sclerosis (SSc) are variable and are associated with a poor prognosis, frequently resulting in impaired right ventricular function and heart failure. A high proportion of patients with SSc experience pulmonary arterial hypertension (PAH), interstitial lung disease, or myocardial involvement, all of which can lead to exercise intolerance. In this context, cardiopulmonary exercise testing (CPET) is a useful tool for diagnosing exercise intolerance, elucidating its pathophysiology, and assessing its prognosis.

Lyme neuroborreliosis can present with isolated neurological manifestations, posing diagnostic challenges, especially in the absence of hallmark dermatological symptoms like erythema migrans. This case highlights a patient with isolated cervical radiculopathy due to Lyme neuroborreliosis, presenting without systemic features such as fever, arthralgia, or rash. The diagnosis was confirmed through serological testing, with positive findings on the Western blot.

The crosstalk between different cell death pathways-such as apoptosis, necroptosis, and neutrophil extracellular trap (NETosis), plays a pivotal role in the pathogenesis of SLE, influencing both cutaneous and cardiac manifestations. Cutaneous lupus erythematosus (CLE) is one of the most common early signs of SLE, affecting up to 80% of patients.
