The Pancreatitis, Panniculitis, and Polyarthritis (PPP) Syndrome: Subcutaneous Nodular Fat Necrosis, a Cutaneous Marker of Pancreatic Neoplasia
The pancreatitis, panniculitis, polyarthritis (PPP) syndrome
is a rare skin, joint, and pancreatic disorder, also known as subcutaneous
nodular fat necrosis. It results from obstruction of pancreatic ducts
with direct secretion of pancreatic enzymes into the bloodstream,
causing extra pancreatic fat necrosis with subcutaneous tissue and
joint inflammation. It is usually a cutaneous sign of pancreatic cancer
or pancreatitis. To our knowledge, this is the first case associated with
a pancreatic pseudotumor. We describe a 59-year-old man initially presenting
with numerous painful erythematous subcutaneous nodules
due to a fibrous pancreatic pseudotumor and its extreme dermatologic
disease, resulting in necrosis of the shin and foot so severe that an amputation
of the lower leg above the knee was required, a complication
not previously described, to our knowledge. We emphasize that PPP
syndrome is a cutaneous marker of internal malignancy, most often of
pancreatic cancer or pancreatitis, but in this case of a rare pancreatic
pseudotumor
Clinical and radiographic evaluation of narrow- vs. regular-diameter dental implants: a 3-year follow-up. A retrospective study
OBJECTIVES: Narrow-diameter implants (NDIs) are used in severely resorbed mandibles. The reduced implant diameter means a reduction in the total contact surface between the implant and bone. The question arises whether the implant can be sufficiently osseointegrated to withstand loading forces. If not, marginal bone loss can result from overload. The aim of this retrospective study was to compare clinical and radiographic measurements and patient satisfaction of NDIs with those of regular-diameter implants (RDIs) placed in edentulous patients to support an overdenture via either a ball or a locator connection. MATERIAL AND METHODS: Retrospectively over a 7-year period, a total 119 patients fulfilled the inclusion criteria and were selected for this study. The patients received two 3.3- or 4.1-mm-diameter standard titanium implants in the mandible to support an overdenture. At maintenance examinations after 1 and 3 years, clinical peri-implant and prosthetic conditions, marginal bone (MB) and patient satisfaction were investigated. RESULTS: None of the 238 implants were lost during the 3-year follow-up period. Overall MB loss was statistically higher in the NDI group when compared with the RDI group. At the site level, a greater MB loss was observed at the distal side of both implant types. Implants with a locator showed significantly greater MB loss (0.38 mm) compared with the implants with a ball attachment (0.14 mm) over the two-year evaluation period (P = 0.006). Patient satisfaction significantly favoured the NDI (8.3) and the locator attachment (8.6). CONCLUSIONS: The results suggest that during the first three years after implantation, NDIs were associated with more marginal bone loss compared with RDIs. Regardless of implant diameter, the locator attachment showed more marginal bone loss over time compared with the ball attachment.status: publishe
