Iliac particulate cancellous bone and marrow (PCBM) is still the most predictable autogenous graft material for vertical ridge reconstruction because of its high cell content as well as osteoinductive and osteoconductive properties. However, postoperative meralgia paresthetica, gait disturbance, pain, and bleeding have been reported following conventional harvesting from the anterior iliac crest. We present a case of minimally invasive harvesting of iliac PCBM. A short incision was made, and the iliac crest was exposed after elevation of the periosteal membrane...

BACKGROUND: This retrospective study evaluated soft-tissue grafting as a surgical treatment option for peri-implantitis in case of unsuitable basic skeletal morphology of the alveolar bone and lack of keratinized mucosa. METHODS: Twenty-eight patients (21 females, 7 males, at a mean age 59.4 years) were included with a total of 54 implants. All implants showed peri-implantitis and attached keratinized buccal mucosa of ≤2 mm. A surgical procedure of soft-tissue grafting (STG) was made by inserting an inlay and inlay-onlay transplant...

BACKGROUND: The damages caused by periodontitis have affected not only periodontal tissues, but have also increased the severity of different illnesses such as: rheumatoid arthritis, diabetes and liver diseases. The aim of this study was to investigate the association between induced periodontitis and the damages caused through its systemic effects on the liver. METHODS: Twenty rats were divided into two groups: control and periodontitis. The following parameters were evaluated: Gingival Bleeding Index (GBI), Probing Pocket Depth (PPD), Myeloperoxidase (MPO) activity, Alveolar Bone Loss (ABL) for periodontal tissues; histopathological examination of gingival and liver tissues; immunohistochemistry to positive cell for neural/glial antigen 2 (NG2) expressed in hepatic pericytes, glutathione (GSH) and malondialdehyde (MDA) concentrations in liver; serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST)...

BACKGROUND: Diagnostic evaluation of patients with diffuse parenchymal lung disease (DPLD) is best achieved by a multidisciplinary team correlating clinical, radiologic, and pathologic features. Surgical lung biopsies remain the gold standard for histopathologic diagnosis of idiopathic interstitial pneumonias. Emerging data suggest an increasing role for transbronchial cryobiopsy (TBC) in DPLD evaluation. We describe our experience with TBC in patients with DPLD. METHODS: We retrospectively reviewed medical records of patients with radiographic features of DPLD who underwent TBC at Mayo Clinic, Rochester, Minnesota in June 2013-September 2015...

BACKGROUND: Prophylactic removal of asymptomatic disease-free impacted wisdom teeth is surgical removal of wisdom teeth in the absence of symptoms and with no evidence of local disease. Impacted wisdom teeth may be associated with pathological changes, such as pericoronitis, root resorption, gum and alveolar bone disease (periodontitis), caries and the development of cysts and tumours. When surgical removal is carried out in older people, the risk of postoperative complications, pain and discomfort is increased...

Diffuse alveolar hemorrhage is a potentially fatal pulmonary disease syndrome that affects individuals with hematological and nonhematological malignancies. The range of inciting factors is wide for this syndrome and includes thrombocytopenia, underlying infection, coagulopathy, and the frequent use of anticoagulants, given the high incidence of venous thrombosis in this population. Dyspnea, fever, and cough are commonly presenting symptoms. However, clinical manifestations can be variable. Obvious bleeding (hemoptysis) is not always present and can pose a potential diagnostic challenge...

Seeds of the castor bean plant Ricinuscommunis L (CB) contain ricin toxin (RT), one of the most poisonous naturally-occurring substances known. Ricin toxin, a water-soluble glycoprotein that does not partition into the oil extract, is a ribosome-inactivating toxin composed of two chains, labeled A and B. Severity of the toxicity varies depending on the route of exposure to the toxin. Inhalational is the most toxic route, followed by oral ingestion. Orally-ingested RT accumulates in the liver and spleen but other cells are also affected...

Extracorporeal Membrane Oxygenation (ECMO) has evolved as a treatment option for patients having potentially reversible severe respiratory failure who are deteriorating on conventional ventilation. During ECMO, systemic anticoagulation is needed to maintain patency of the circuit. Therefore, ongoing haemorrhage remains a relative contra-indication to ECMO as it can further increase the bleeding. There is only limited evidence available for the use of ECMO in patients with alveolar haemorrhage. Most of these patients did not receive any anticoagulation during ECMO...

Hermansky-Pudlak Syndrome type-1 (HPS-1) is an autosomal recessive disorder caused by mutations in HPS1 which result in reduced expression of the HPS-1 protein, defective lysosome-related organelle (LRO) transport and absence of platelet delta granules. Patients with HPS-1 exhibit oculocutaneous albinism, colitis, bleeding and pulmonary fibrosis postulated to result from a dysregulated immune response. The effect of the HPS1 mutation on human mast cells (HuMCs) is unknown. Since HuMC granules classify as LROs along with platelet granules and melanosomes, we set out to determine if HPS-1 cutaneous and CD34+ culture-derived HuMCs have distinct granular and cellular characteristics...

BACKGROUND: Regenerative periodontal therapy encompasses the use of various bioactive agents that are not only inflammo-modulatory but also osteoclast-inhibitory or rather, osteostimultive. The hypolipidaemic Statin group of drugs, particularly Rosuvastatin (RSV), are known to be associated with alveolar bone formation and periodontal improvements. Platelet analogues like Platelet rich fibrin (PRF), being rich sources of growth factors, have also come into widespread periodontal regenerative use...

Acute pulmonary emphysema (APE) has been described in cases of mechanical asphyxia such as ligature or manual strangulation but not in cases of hanging. In this study, we wanted to verify by morphometric digital analysis of lung tissue whether APE occurs in death by hanging.We investigated 16 cases of hanging (eight complete, eight incomplete), 10 cases of freshwater drowning (positive control group), and 10 cases of acute external bleeding (negative control group). Tissue sections were obtained from each pulmonary lobe...

Endoscopic treatment of emphysema is supported by different methods, including valves, coils and sealants. The mechanism is mainly related to volume reduction of targeted area. Endobronchial valves (EBV) appear the most studied method. In a multicentre randomised study, placement of unidirectional endobronchial valves resulted in a statistically significant functional improvement in the treated cohort compared to the control. Adverse events, occurring post procedure, included COPD exacerbations, haemoptysis, pneumothorax and pneumonia...

Numerous adverse effects follow anabolic agent abuse. Pulmonary hemorrhage is not considered one of them. We present two cases of young male bodybuilders who developed diffuse alveolar bleeding as a result of anabolic steroid abuse. Diffuse alveolar hemorrhage associated with anabolic agent abuse has not been described previously in the literature. Both patients developed acute dyspnea and hemoptysis with consistent radiological findings. In both cases symptoms promptly resolved with cessation of exposure and no medical intervention was required and no signs of persistent lung damage were seen...
