Abstract

Intermittent parathyroid hormone (PTH) administration is known to promote bone healing after surgical procedures. However, the mechanism and influence of PTH on the mineral and collagen quality of the jaw are not well understood. Most studies have focused on analyzing the bone density and microstructure of the mandible, and have insufficiently investigated its mineral and collagen quality. Oxidative stress activates osteoclasts, produces advanced glycation end products, and worsens mineral and collagen quality. We hypothesized that PTH induces oxidation and affects the mineral and collagen quality of newly formed mandibular bone. To test this, we examined the mineral and collagen quality of newly formed mandibular bone in rats administered PTH, and analyzed serum after intermittent PTH administration to examine the degree of oxidation. PTH administration reduced mineralization and worsened mineral and collagen quality in newly formed bone. In addition, total anti-oxidant capacity in serum was significantly decreased and the oxidative-INDEX was increased among PTH-treated compared to vehicle-treated rats, indicating serum oxidation. In conclusion, intermittent administration of PTH reduced mineral and collagen quality in newly formed mandibular bone. This effect may have been induced by oxidation.

Impacted primary teeth can be caused by odontogenic tumors such as odontomas, cystic diseases such as dentigerous and eruption cysts, and fibrous hyperplasia of the gingiva, while elimination of those causes reportedly results in normal eruption of primary teeth. We describe the course of a child from the age of 1 year until 4 years 10 months who had primary tooth eruption failure and was treated with dental methods. Although primary teeth expected to spontaneously erupt were followed, there were several on the left side that remained unerupted. We performed a left maxillary and mandibular gingivectomy to closely examine the cause of eruption delay and tooth germ dislocation, as well as attempt to induce eruption of the primary teeth. Based on histopathological results, the diagnosis was fibroma. Surgical procedures did not result in clear improvement of eruption failure. In order to improve masticatory function and aesthetics, the child was fixed with an artificial denture for all primary teeth not expected to erupt. (C) 2018 Japanese Society of Pediatric Dentistry.

Chihiro Tanikawa, Kae Hirata, Tomonao Aikawa, Jun Maeda, Mikihiko Kogo, Seiji Iida, Takashi Yamashiro

The Cleft palate-craniofacial journal : official publication of the American Cleft Palate-Craniofacial Association 55 ( 10 ) 1375 - 1381 2018.11

Language：English

OBJECTIVES: To evaluate the effects of maxillary anterior segmental distraction osteogenesis (MASDO) in patients with cleft lip and palate (CLP) and to identify risk factors for increased relapse. DESIGN: A retrospective study. PATIENTS: Thirty-one Japanese patients with CLP who underwent MASDO were eligible for study inclusion. MAIN OUTCOME MEASURES: We evaluated lateral cephalograms obtained before (T1), at 3 months (T2), and at 1 year (T3) after MASDO, and measured changes from T1 to T2 (δT1T2), from T2 to T3 (δT2T3), and from T1 to T3 (δT1T3). We also evaluated the risk factors associated with an increased relapse. RESULTS: Overall (δT1T3), MASDO improved retrusion of the maxilla. We measured a significant advancement (6.1 mm) of the anterior maxillary segment in δT1T2 (A-McNamara classification) and increases in the overjet and the SNA, ANB, and nasolabial angles. However, skeletal relapse was evident in δT2T3, and the median percentage of relapse was 10%. To explore the risk factors, we subdivided patients with a δT1T2 of >5 mm into 2 groups based on the percentage of relapse (>15% vs ≤15%). There were significant differences between these groups in the vertical positions of the anterior nasal spine and point A, and the angle formed by the SN and palatal planes (SNPP), suggestive of intraoperative counterclockwise rotation of the maxilla. CONCLUSIONS: MASDO is effective for correcting midfacial deficiencies, but counterclockwise rotation of the maxilla during surgery may cause relapse.

Language：English Publishing type：Research paper (scientific journal) Publisher：ELSEVIER SCIENCE BV

Odontomas are generally encountered in permanent dentition and rarely seen in primary dentition. These lesions are regarded as essentially benign, though they often cause disturbances in eruption of the associated tooth. We present clinical findings and management of 3 cases of odontomas that occurred in primary dentition, including a 3-year-old girl referred for examination of an unerupted left upper primary canine, a 6-year-old boy with an unerupted left lower second primary molar, and a 5-year-old girl who was presented with an unerupted right upper second primary molar. In all cases, periapical and panoramic radiography revealed a radio-opaque mass surrounded by a narrow radiolucent space located above the crown of the unerupted tooth. Each was diagnosed as a compound odontoma interfering with eruption of a primary tooth and surgical removal was performed under general anesthesia for all patients, with the final diagnosis based on histological findings. Following surgery, the primary canine in Case 1 spontaneously erupted, while a space maintenance appliance was applied in Case 2 and 3. It is important to recognize that an odontoma can appear in primary dentition, though the incidence is quite low. Early detection and removal of an odontoma associated with an impacted primary tooth is necessary for optimal dentition.

Journal of cell communication and signaling 12 ( 1 ) 245 - 252 2018.3

Language：English Publishing type：Research paper (scientific journal)

The CCN family consists of 6 genes in the mammalian genome and produces multifunctional proteins involved in a variety of biological processes. Recent reports indicate the profound roles of CCN2 in energy metabolism in chondrocytes, and Ccn2 deficiency is known to alter the expression of 2 other family members including Ccn3. However, almost nothing is known concerning the regulation of the CCN family genes by energy metabolism. In order to gain insight into this critical issue, we initially and comprehensively evaluated the effect of inhibition of glycolysis on the expression of all of the CCN family genes in chondrocytic cells. Upon the inhibition of a glycolytic enzyme, repression of CCN2 expression was observed, whereas CCN3 expression was conversely induced. Similar repression of CCN2 was conferred by the inhibition of aerobic ATP production, which, however, did not induce CCN3 expression. In contrast, glucose starvation significantly enhanced the expression of CCN3 in those cells. The results of a reporter gene assay using a molecular construct containing a CCN3 proximal promoter revealed a dose-dependent induction of the CCN3 promoter activity by the glycolytic inhibitor in chondrocytic cells. These results unveiled a critical role of glycolytic activity in the regulation of CCN2 and CCN3, which activity mediated the mutual regulation of these 2 major CCN family members in chondrocytes.

The influence of zoledronate and teriparatide on gamma delta T cells in mice Reviewed International journal

Yamachika Eiki, Matsui Yuichi, Matsubara Masakazu, Matsumura Tatsushi, Nakata Naoki, Moritani Norifumi, Ikeda Atsushi, Tsujigiwa Hidetsugu, Ohara Naoya, Iida Seiji

Language：English Publishing type：Research paper (scientific journal)

Background/purpose: Few studies have investigated the possibility that bisphosphonate-related osteonecrosis of the jaw (BRONJ) might reflect an immune response; however, gamma delta T cells have been shown to significantly decline in the blood of BRONJ patients. Additionally, there have been some reports of teriparatide usage for the treatment of BRONJ. In this study, we compared the effects of zoledronate and teriparatide on lymphocyte populations and inflammatory cytokine production in mice. Materials and methods: Thirty female ICR mice were divided into three groups (n = 10 each): a vehicle, a zoledronate, and a teriparatide group. Drugs were administered for 8 weeks in each group. Lymphocytes in the blood and thymus were analyzed and femurs were used for histological observation and lymphocytes analysis of bone marrow. Cytokines were measured in separated serum using Milliplex® multiplex immunoassay analysis. Results: Zoledronate decreased the T cell number in the bone marrow. Additionally, serum levels of interleukin (IL)-2, IL-7, IL-12, IL-15 and RANTES, which are cytokines that affect T cell activation, differentiation and/or proliferation, were significantly lower in zoledronate treated mice. Conversely, teriparatide treatment induced an increase in gamma delta T cells in peripheral blood. Conclusion: Gamma delta T cells in the bone marrow are expected to decrease with zoledronate treatment and increase with teriparatide treatment. If BRONJ involves a loss of gamma delta T cells in the circulation or bone marrow, then the increase in gamma delta T cells that is induced by teriparatide may account for its ability to resolve BRONJ.

Platinum-based chemotherapy plus cetuximab represents the first-line treatment for recurrent or metastatic squamous cell carcinoma of the head and neck. The most common adverse events associated with cetuximab are infusion reactions and skin reactions, and a risk of venous thromboembolic events has also recently been reported in association with cetuximab. It is well known that thrombosis is a common complication of malignancy, and represents the second most frequent cause of mortality in cancer patients. The present study reports the case of a 79-year-old man who presented with lung and liver metastases from tongue squamous cell carcinoma, for which platinum-based chemotherapy plus cetuximab was administered. After 1 cycle, the patient showed rapid growth of a left ventricular (LV) thrombus, despite ongoing antiplatelet therapy for an old myocardial infarction. Anticoagulant therapy was administered to treat the LV thrombus, which resolved within 1 week. To the best of our knowledge, this represents the first reported case of rapidly occurring LV thrombus associated with platinum-based chemotherapy plus cetuximab. Platinum-based chemotherapy plus cetuximab may be associated with a higher risk of embolic thrombus.
