Fragmentation of QRS (fQRS) complex is an easily evaluated non-invasive electrocardiographic parameter. Fragmentation of narrow QRS is defined as presence of an additional R wave (R') or notching in the nadir of the S wave, or the presence of > 1 R' in 2 contiguous leads, corresponding to a major coronary artery territory on the resting 12-lead ECG. Fragmentation of wide complex QRS consists of...

the immunopathology of sarcoidosis remains elusive despite years of research into this multiorgan disease.however, recent studies have provided new insights into the genetics and immune components involved in the clinical manifestation of the disease. granulomatous inflammation is due to the host immune response to a persistent poorly degradable unknown antigen.mycobacterium tuberculosis (mtb) ...

According to the literature, intense pulsed light (IPL) represents a versatile tool in the treatment of some dermatological conditions (i.e., pigmentation disorders, hair removal, and acne), due to its wide range of wavelengths. The authors herein report on 58 unconventional but effective uses of IPL in several cutaneous diseases, such as rosacea (10 cases), port-wine stain (PWS) (10 cases), di...

Thirty patients with bilateral lymph node enlargement with or without parenchymal infiltrates on the chest x- ray suspected to have sarcoidosis were studied between June 1980 and December 1989 in our institution. Eleven of these patients who were free of parenchymal infiltrates did not have a biopsy performed and the diagnosis of sarcoidosis was made based on self-limited regression and cl...

Introduction: A case of pulmonary sarcoidosis is reported because of difficulties in diagnosis and treatment, including the co-existence of ankylosing spondylitis (AS) and severe corticosteroid dependence. Case Presentation: A 48-year-old nonsmoking woman referred to the hospital because of chronic nonproductive cough and dyspnea with a 10-year history of...

Sarcoidosis is a multisystem granulomatous disease of unknown origin. The most frequent localizations are thoracic lymph nodes and/or parenchymal lung disease, nevertheless any other organ may be involved. Musculoskeletal sarcoidosis, previously considered rare manifestation the presently recognized with increasing frequency, due to development modern imaging modalities. classical X-ray sign bo...

We report a three-phase bone scintigraphy for the diagnosis of a peripheral bone lesion caused by systemic sarcoidosis. A 32-year-old man with suspected osteomyelitis of the right forefinger underwent three-phase bone scintigraphy with Tc-99m hydroxymethylene diphosphonate (HMDP) and single-photon emission computed tomography/computed tomography (SPECT/CT). The lesion was rich in blood flow acc...

Pyrexia of unknown origin (PUO) is a common problem in day-to-day practice. FDG PET CT is an established investigation that aids in identifying the cause of PUO. Due to its high sensitivity PET detects an occult hypermetabolic focus in the body where CT helps in anatomical localization, vascularity, enhancement characteristics of the lesion detected on PET. It helps to differentiate benign vers...

background sarcoidosis is a multisystem disease affecting different organs with different frequency rates depending on geographical location. musculoskeletal abnormalities includes osseous lesions (small and large bone sarcoidosis), sarcoidal arthropathy, and sarcoidal myopathy. musculoskeletal involvement is reported in a significant number of patients. objectives this study aimed to determine...

Sarcoidosis and foreign body reactions are common differential diagnoses of skin granuloma formation. We report a 40 year –old man with sarcoid type granulomas containing polarized foreign materials, and also bilateral hilar adenopathy. It appears that detection of foreign bodies in histopatologic studies of granulomas does not necessarily exclude the possibility of sarcoidosis.
