Juvenile Hyaline Fibromatosis: A 10-year Follow-up.

Juvenile hyaline fibromatosis (JHF) is a rare hereditary disease with an autosomal recessive transmission. JHF is characterized by papulonodular skin lesions, osteolytic bone lesions, flexural joint contractures, and gingival hyperplasia and usually diagnosed in infancy or early childhood. JHF is thought to be a disorder of collagen metabolism and characterized by homogenous amorphous eosinophilic material and fibrous tissue.

Proinflammatory and anti-inflammatory cytokines in gingival crevicular fluid and serum of patients with rheumatoid arthritis and patients with chronic periodontitis.

Background: The aim of this study is to evaluate proinflammatory and anti-inflammatory cytokine levels in gingival crevicular fluid (GCF) and serum of rheumatoid arthritis (RA) and chronic periodontitis (CP) patients to assess whether cytokine profiles distinguish patients with RA and patients with CP while using healthy patients as background controls.

Methods: A total of 49 patients, 17 patients with RA (three males and 14 females; mean age: 47.82 ± 10.

Nitric oxide in gingival crevicular fluid and nitric oxide synthase expression in the gingiva of patients with sickle cell disease.

Objective: This study aimed to biochemically measure the production of nitric oxide in gingival crevicular fluid and immunohistochemically measure the expression of inducible nitric oxide synthase in the gingiva of patients with sickle cell disease. Additionally, we aimed to obtain insight into the immunopathology of sickle cell disease by comparing inducible nitric oxide synthase levels in patients with sickle cell disease and controls using gingiva and gingival crevicular fluid.

Methods: The study included 20 sickle cell disease patients and 20 healthy controls.

Coronectomy in patients with high risk of inferior alveolar nerve injury diagnosed by computed tomography.

Purpose: Previous studies have suggested coronectomy as an alternative procedure to decrease the risk of inferior alveolar nerve (IAN) injury when there are high-risk findings observed on panoramic radiographs. However, the exact relation between the inferior alveolar canal and the roots is not obvious on 2-dimensional imaging. The aim of this study was to evaluate the success of coronectomy by comparing it with conventional extraction for the treatment of the patients who had clear IAN injury risks that were determined on 3 dimensions by computed tomography.

Nitric oxide synthase in gingival tissues of patients with chronic periodontitis and with and without diabetes.

Background: The purpose of this study was to evaluate the expression of inducible nitric oxide synthase (iNOS) in the gingival tissues of periodontitis patients with and without type 2 diabetes to assess whether NO plays a role in the severity of periodontitis in patients with diabetes. Patients with diabetes and healthy patients were used as controls.

Methods: A total of 80 patients were evaluated in four groups (with 20 subjects each): patients with chronic periodontitis and diabetes (12 males and eight females; mean age, 52.

Alport syndrome: significance of gingival biopsy in the initial diagnosis and periodontal evaluation after renal transplantation.

Alport Syndrome (AS) is an important hereditary disorder affecting the glomerular basement membrane. Diagnosis of AS is based on the presence of hematuric nephropathy, renal failure, hearing loss, ocular abnormalities and changes in the glomerular basement membrane of the lamina densa. The aims of this case report were to show the changes in the gingival tissues in a patient with AS under therapy with cyclosporin-A after renal transplantation and to discuss the possible role of type IV collagen in gingival basal lamina as an alternative approach for the diagnosis of AS.

The role of oral hygiene in a patient with idiopathic thrombocytopenic purpura.

Objective: Idiopathic thrombocytopenic purpura (ITP) is an acquired disease of children and adults defined as isolated thrombocytopenia with no clinically apparent associated conditions or other causes of thrombocytopenia. Oral manifestations are gingival bleeding, petechiae, mucocutaneous bleeding and haemorrhage into tissues.

Case Description And Results: An 11-year-old Turkish female was referred to the periodontology clinic by the paediatric haematologist for the treatment of spontaneous gingival bleeding, gingival oedematous enlargement and hyperaemia.

Oral health-related quality of life and periodontal health status in patients undergoing hemodialysis.

Background: Health-related quality of life (HRQOL) is a multidimensional concept regarding quality of life (QOL) as it relates specifically to health and disease. The effect of ongoing hemodialysis on a person's oral health can be determined by clinical variables, but these do not reflect the person's perception of health versus illness. The authors conducted a study to determine the periodontal status, attitude toward oral health and self-perceived oral health in patients undergoing hemodialysis, as well as to evaluate the effect of oral health on QOL within this group.

Long-term clinical evaluation and SEM analysis of the e-PTFE and titanium membranes in guided tissue regeneration.

Aim: This study aimed to evaluate clinical outcomes of titanium membrane and compare these findings with clinical outcomes of e-PTFE membrane, and to investigate the effect of bacterial contamination on both membranes with SEM during long-term healing.

Results: Sixteen titanium and sixteen e-PTFE membranes were surgically placed adjacent to periodontally involved teeth. Seven titanium and 8 e-PTFE membranes were exposed between 4 and 6 weeks.

Pain perception and anxiety during scaling in periodontally healthy subjects.

Background: Dental pain, anxiety, and fear may result in avoiding dental treatment. In this study, we aimed to evaluate patients' pain perception during scaling and its relationship with dental anxiety.

Methods: One hundred thirteen patients (72 women and 41 men; mean age, 35.

Interleukin-1 and tumor necrosis factor-alpha gene polymorphisms in Turkish patients with localized aggressive periodontitis.

Localized aggressive periodontitis (LAgP) is a complex multifactorial periodontal disease to which genetic factors are thought to predispose individuals. Interleukin-1 (IL-1) and tumor necrosis factor-alpha (TNF-alpha) are potent immunomodulators and proinflammatory cytokines that have been implicated in the pathogenesis of autoimmune and infectious diseases and proposed to be risk factors for LAgP. Our aim was to investigate IL-1 alpha (+4845), IL-1 beta (+3954), and TNF-alpha (-308) gene polymorphisms in Turkish LAgP patients.

Comparison of sciatic psoas compartment block and sciatic femoral 3-in-1 block for knee arthroscopy.

Study Objectives: To compare the clinical effectiveness of two peripheral nerve block techniques combined with sciatic nerve block: sciatic psoas compartment (SPC) and sciatic femoral 3-in-1 (SF 3-in-1) block.

Design: Prospective, randomized study.

Setting: Military medical academy hospital.

Periodontal health and adverse pregnancy outcome in 3,576 Turkish women.

Background: Preterm low birth weight (PLBW) is a problem encountered worldwide. The many causes of low birth weight (LBW) and premature or preterm birth (PTB) vary among developing/industrialized countries. Few studies have been published, in part because of the paucity of subjects and the ethnic heterogeneity of the populations.

Combined therapy in a patient with Papillon-Lefèvre syndrome: a 13-year follow-up.

Background: Papillon-Lefèvre syndrome (PLS) is an autosomal recessive disease characterized by hyperkeratosis of the palms and soles combined with premature loss of the primary and permanent dentition. Several treatment regimens have been recommended in the literature; however, a definitive treatment protocol has not been established. This case report evaluates the success of combined therapy in managing a patient with PLS.

Excessive gingival bleeding in two patients with Glanzmann thrombasthenia.

Background: Glanzmann thrombasthenia (GT) is an exceedingly rare but well-defined inherited disorder of platelet function caused by a defect in the glycoprotein IIb/IIIa complex. The association of GT with consanguinity has been noted, especially in geographic regions in which intermarriage is common. In most patients, GT is diagnosed during early infancy or before the age of 5 years.

From alveolar diffuse atrophy to aggressive periodontitis: a brief history.

Technologic advances in mechanics, electronics, physics, chemistry, and computer science have contributed to advances in dental medicine. Periodontology is not only a clinical science but is also directly related to the basic sciences. Research is conducted in laboratories rather than in clinics now.

Three siblings with juvenile hyaline fibromatosis.

Juvenile hyaline fibromatosis (JHF) is an extremely rare hereditary genetic disease of autosomal recessive transmission that is characterized by large cutaneous tumors commonly involving the scalp, papulonodular skin lesions, flexural joint contractures, gingival hyperplasia, and osteolytic bone lesions. JHF is usually diagnosed in young infants and in children younger than 5 years, and the lesions characteristic of this disorder consist of fibrous tissue and homogenous amorphous eosinophilic hyaline material. We report the case of a 9-year-old girl with severe gingival hyperplasia, nasal enlargement, mild osteoporosis, and multiple papulonodular skin lesions.

Topical cannabinoid antinociception: synergy with spinal sites.

Analgesic effects of cannabimimetic compounds have been known to be related to their central effects. Cannabinoid receptors also exist in the periphery but their role in pain perception has been remained to be clarified. Therefore, we assessed topical antinociceptive effects of WIN 55, 212-2, a mixed CB(1) and CB(2) receptors agonist, in mice using tail-flick test.

Severe rhabdomyolysis due to malignant hyperthermia during renal transplantation procedure can cause delayed graft function.

A case of rhabdomyolysis from malignant hyperthermia occurred during renal transplantation surgery is presented. After the completion of vascular and uretherovesical anostomosis, the patient's heart rate began to rise, sweatiness was observed and body temperature increased to 41 degrees C. Additionally, metabolic and respiratory acidosis and hyperkalemia were detected.

L-type and T-type calcium channel blockade potentiate the analgesic effects of morphine and selective mu opioid agonist, but not to selective delta and kappa agonist at the level of the spinal cord in mice.

We examined the effects of amlodipine, a selective L-type voltage dependent Ca(2+) channel (VDCC) blocker, and mibefradil, a selective T-type VDCC blocker on the antinociceptive effects of morphine, and mu, delta and kappa opioid receptor selective agonist-induced antinociception at the spinal level. Intrathecally administered amlodipine and mibefradil potentiated morphine and [D-Ala(2), N mePhe(4), Gly-ol(5)] enkephalin (DAMGO)-induced antinociception by shifting their dose response curves to the left. However, intrathecally administered amlodipine and mibefradil did not affect [D-Pen(2), D-Pen(5)]enkephalin (DPDPE) and [trans-(+/-)-3,4-dichloro-N-methyl-N-[2-(1-pyrolidinyl)cyclohexyl] benzene acetamide (U-50, 488H)-induced antinociception.
