Thirty-four patients with mandibular diffuse sclerosing osteomyelitis who had been treated by means of 61 decortications were evaluated retrospectively. Eighteen patients (53%) were free from symptoms on an average of 5.4 years after surgery. Of these, 12 had improved after their first operation. In the other six patients, decortication was performed two to four times before healing was clinically observable. Symptoms recurred in 75% of the cases within 12 months after surgery. Neither sex, location, extent, and chronicity of the disease nor the precise surgical technique used seemed to affect the outcome. The patients who exhibited improvement, however, were significantly older and more often edentulous than the patients in whom the symptoms recurred. Possible causes of failure were an insufficiently radical surgical procedure and retention of devitalized teeth in the decorticated area.

Introduction: Sarcoidosis is a multisystem inflammatory disease of unknown etiology characterized by the formation of noncaseating epithelioid granulomas. Clinically significant renal involvement is rare in sarcoidosis. It most commonly manifests as chronic tubulointerstitial nephritis and nephrocalcinosis with nephrolithiasis.

Objective: Distinguishing grade 3 pancreatic neuroendocrine tumors (PanNETs) from neuroendocrine carcinomas (PanNECs) is sometimes challenging. Recently, a diffuse p16-positive pattern was reported in PanNECs but not in grade 3 PanNETs, suggesting that p16 could help differentiate these entities. This study aimed to investigate p16 expression in PanNETs of various grades and its association with clinicopathologic features.

Diffuse sclerosing osteomyelitis (DSO) is a non-bacterial disease of the jawbone, characterized by intermittent pain, swelling, and a mixture of osteosclerosis and osteolysis on radiographs. Its etiology remains unclear, and a standard treatment, based on clear diagnostic criteria, has not been established. We present the case of a 48-year-old male patient, who was initially diagnosed with chronic mandibular osteomyelitis due to apical periodontitis in the right lower second premolar, and underwent antimicrobial medication and surgical therapy based on computed tomography (CT), magnetic resonance imaging (MRI), and bone scintigraphy.

Proliferations of neoplastic perivascular epithelioid cells (PECs) may occur within the lung and extrathoracic sites. The term "PEComatosis" is applied to multiple or diffuse microscopic proliferations of neoplastic PECs. Pulmonary diffuse PEComatosis is extremely rare, with only one case documented in the literature to date.

The connection between Primary sclerosing cholangitis (PSC) and lymphoma remains uncertain. To address this, Mendelian randomization (MR) was utilized to investigate the potential causal links between PSC and lymphoma. A 2-sample MR analysis was conducted utilizing summary-level data obtained from genome-wide association study datasets.
