Background: Antiresorptive drugs are widely used to reduce bone mineral loss in patients with osteoporosis and to prevent skeletal-related events in patients with metastatic cancers and multiple myeloma (MM). Both the bisphosphonates (BP) and denosumab typically used in this indication were shown to be effective and relatively safe. Obviously, this medication could have some adverse effects; one of them is osteonecrosis of the external auditory canal. Only sporadic cases of external auditory canal osteonecrosis have been published yet. Here, we provide a case of denosumab-related osteonecrosis of the external auditory canal successfully treated surgically in the early stage of the disease. Case report: A 68-year-old patient with breast cancer underwent comprehensive oncological treatment, including denosumab administration. She was diagnosed with osteonecroses in the jaw and ear canal. The necrotic bones in both regions were resected with primary wound closure. Both affected sites healed well with no signs of necrosis recurrence. Conclusions: Osteonecrosis of the external auditory canal is a rare but probably underdiagnosed complication of antiresorptive medication. It has a negative impact on patient quality of life if left untreated. Early surgical treatment appears to be effective. The authors highlight several similarities with medication-related osteonecrosis of the jaw. Therefore, an analogous disease staging and treatment rationale is suggested.

This research to analyze the impact of closure policy Teleju brothel by Pekanbaru govermentin 2010. Guidelines for works are Pekanbaru Local Regulations No. 12 of 2008 on Social Order-liness. Closure this brothel inflicts positive and negative impact for society.The research wasconducted to obtain early stage formula for the government to take action against the prostitu-tion activities. This research uses policy research approach with a qualitative method, becausein prostitution activities and prohibition by goverment is an assessment that needs to be done byanalyzing documents and unstructured interview.The results showed that after the closing of the Teleju brothel have an impact on the deploy-ment of a prostitution and affect the economy of the surrounding residents. Government seeksto tackle prostitution in Pekanbaru by moving the brothel, conduct regular raids and providetraining. The effort is considered to be less than the maximum because the handling is not basedon the root of the problem and not programmed properly. There are several causes of failure ofgovernment to overcome the prostitution problem in Pekanbaru, including: policy content isless focus on the prostitution problem, the government did not proceeds with data, lack of finan-cial support, contra productive programs between local government with the police and TNI,and the policy object is difficult to be given understanding.

Objective To determine the incidence of skeletal-related events among multiple myeloma patients who received chemotherapy without a bone-modifying agent (zoledronic acid and denosumab) versus those who received chemotherapy with a bone-modifying agent. The secondary objective was to determine the incidence of skeletal-related events in patients without any prior history of skeletal-related events and who were treated with zoledronic acid every four weeks versus those who received zoledronic acid at an extended interval of every twelve weeks. Additional secondary objectives included the incidence of nephrotoxicity, hypocalcemia and osteonecrosis of the jaw in all patients. Methods This institutional review board-approved, retrospective cohort study included patients 18 to 89 years old with a diagnosis of multiple myeloma, who were being treated with chemotherapy between July 1, 2016 and October 31, 2019. Safety and efficacy were assessed through analysis of pertinent data collected: patient demographics, baseline skeletal-related events, development of new skeletal-related events, number and type of bone-modifying agent doses administered, and drug-related toxicities such as nephrotoxicity, hypocalcemia, and osteonecrosis of the jaw. Results A total of 73 patients were included. New skeletal-related events occurred in 12 patients (27%) in the chemotherapy without a bone-modifying agent group and in 5 patients (17%) in the chemotherapy with a bone-modifying agent group (OR = 0.56, 95% CI [0.172–1.8]; P = 0.32). The incidence of skeletal-related events was similar among patients receiving zoledronic acid every four weeks versus every twelve weeks in patients without a prior skeletal-related event (N = 0 vs. N = 2 respectively; P = 0.47). There were no statistically significant differences observed in each of the three secondary safety endpoints: incidence of hypocalcemia, nephrotoxicity and osteonecrosis of the jaw. Conclusion Multiple myeloma patients receiving chemotherapy without a bone-modifying agent had higher rates of skeletal-related events compared to those being treated with chemotherapy and a bonemodifying agent. Our results highlight the benefit of utilizing bonemodifying agents for the prevention of skeletal-related events in all multiple myeloma patients being treated with chemotherapy.

Medication-induced jaw osteonecrosis (MRONJ) is a rare and serious disease with a negative impact on patients’ quality of life, whose exact cause remains unclear and which may have a multifactorial origin. Although there are different therapeutic protocols, there is still no consensus. This case series evaluated three patients diagnosed with staged 2 MRONJ treated at the University of Murcia dental clinic according to the protocols described by the Spanish Society of Oral and Maxillofacial Surgery and the American Association of Oral and Maxillofacial Surgeons. Within 12 months of the application of therapeutic protocols, the lesions were completely healed in all cases. Radiography showed slow but progressive healing with normal bone structure. Conservative treatment with antibiotics, chlorhexidine rinses and minimally invasive surgical intervention with necrotic bone resection is effective in treating stage 2 of MRONJ. In cases of refractory osteonecrosis, the application of platelet and leukocyte-rich fibrin (PRF-L) in the surgical approach improves the outcome in soft tissue healing and bone regeneration but further research is needed to confirm its effectiveness.

Osteonecrosis of the jaw (ONJ) is a severe clinical condition characterized mostly but not exclusively by an area of exposed bone in the mandible and/or maxilla that typically does not heal over a period of 6–8 weeks. The diagnosis is first of all clinical, but an imaging feedback such as Magnetic Resonance is essential to confirm clinical suspicions. In the last few decades, medication-related osteonecrosis of the jaw (MRONJ) has been widely discussed. From the first case reported in 2003, many case series and reviews have appeared in the scientific literature. Almost all papers concerning this topic conclude that bisphosphonates (BPs) can induce this severe clinical condition, particularly in cancer patients. Nevertheless, the exact mechanism by which amino-BPs would be responsible for ONJ is still debatable. Recent findings suggest a possible alternative explanation for BPs role in this pattern. In the present work we discuss how a condition of osteomalacia and low vitamin D levels might be determinant factors.

Background: Medication-related osteonecrosis of the jaw (MRONJ) is a potentially severe complication of mainly antiresorptive drugs. We evaluated the frequency of dentoalveolar pathologies in patients scheduled for antiresorptive therapy in a ‘real-world’ setting, also including patients with poor oral health potentially requiring tooth extractions and/or other dentoalveolar surgery. This approach is in contrast to the setting of recent randomized trials with restrictive exclusion criteria. Patients & methods: We prospectively included patients suffering from solid tumors with osseous metastases or multiple myeloma. Screening for dentoalveolar pathologies was done prior to initiation of antiresorptive therapy at the specialized MRONJ clinic of the University Hospital for Cranio-Maxillofacial and Oral Surgery, Innsbruck, Austria. Results: 119 subjects could be included. In 76 patients (63.9%), a dental focus was revealed including deep caries (24.4% of patients), chronic apical periodontitis (26.9%), periodontal disease (45.8%), root remnants (16%), jaw cysts (2.5%), partially impacted teeth (5.0%) and peri-implantitis (5.0%). Conclusion: Considering the high number of dentoalveolar pathologies (63.9%), systematic dental focus screening prior to initiation of antiresorptive therapy is of utmost importance to lower the risk for MRONJ.

It is essential that oncological patients treated with antiresorptives or antiangiogenic drugs diagnosed Medication Related Osteonecrosis of the Jaw (MRONJ) must be treated in an interdisciplinary fashion. The patient’s stomatognathic system should be examined preventatively prior to the initiation of antiresorptive drugs in order to avoid pathological buccal manifestations, following the same healthcare clinical protocols used for patients receiving head and neck radiotherapy. Additionally, patients should be informed of the precautions to be taken, including regular dental appointments for oral health assessment. The risk of developing MRONJ should be evaluated according to the type of antiresorptives or antiangiogenic drugs administered and treatment duration. In the case of MRONJ, its fundamental characteristic is positioned in the biochemical particularity of the pharmacokinetic expression of antiresorptive drugs, reversibly (DS) or irreversibly (BPs) inhibiting the functionality of the osteoclast. Therefore, the consideration of invading bone tissue as little as possible and performing resective therapies in cases of systemic infectious spread follows, since its long-term resolution would not be effective because the drug (BPs) has frank accumulation at a distance, a characteristic used by treating doctors and it would not have clinical relevance to suggest its suspension. According to the recommendations of AAOMS; Task Force and AOCMF coincide with the sharing of consensus on minimally invasive manipulations once the necrotic foci have been installed and the preventive attitude prevails of eliminating all septic foci prophylactically before starting therapy with antiresorptive drugs. There are positions with a trend more committed to frank bone manipulation with the aim of evacuating the infectious problem and other more conservative positions in order not to expand drug necrosis volumetrically due to bone accumulation of BPs or DS.

This study was based on the findings during teaching and learning process at FKIP Universitas Dehasen Bengkulu (the Faculty of Educational Science and Teacher Training of Dehasen University of Bengkulu). There was a phenomenon of declining of good character value and morality. This is because of the misused of advancing technology by students that brings negative impact on the students' character and morality. This phenomenon was especially found among new students of FKIP (Faculty of Educational Science and Teacher Training) on their early stage of study. At the meeting of Educational Profession (Profesi Pendidikan) course, we did early observation by making contract with the new student.. They generally still brought their local character and moralor their old behavior. This could be seen, for example, they talked to their lecturers and seniors impolitely or often used their local language.  Everyone's patience was needed in dealing withthis phenomenon. As the lectures progressed, especially Educational Profession course, we tried to internalize character values toward the students. This had positive impact for them. Today, they are found to be more polite, for example, they greet their lecturers and seniors when they meet them. This study dealt with character values such as: religious, discipline, honest, hard work, responsible, love peace, appreciate achievements, and friendly or communicative. This Exploratory study which was done to internalize character value of the students, has positive impact, this can be seen fromthepositive progress of students' character. Students who already have good character will keep learning to have better personality. This wil affect their future job, especially if they become teachers.

Introduction. Granulosa cell tumors are rare neoplasms of ovary with low malignancy potential and late recurrence. They originate from the granulose of the ovary stromal cells and have the ability to produce estrogens. The main treatment is surgical and implies hysterectomy with bilateral salpingo-oophorectomy, omentectomy, taking peritoneal biopsies, and cytological analysis of the peritoneal washing. When found in young women who have not given birth, a conservative approach can be considered. Fertility sparing surgery is safe only for early FIGO stages IA tumors ?? IC, where it is necessary to make unilateral salpingo-oophorectomy and complete staging. Case outline. We present a case of young woman with granulosa cell tumor who was accidentally discovered, and after an adequate surgery and chemotherapy she gave a birth to a healthy child. Conclusion. Young women who have not given birth and who have been diagnosed with granulosa cell ovarian tumor can be treated conservatively after adequate disease staging and confirmation that the disease is at an early stage.

Antiresorptive agent-related osteonecrosis of the jaw (ARONJ) is a dreaded complication in patients with compromised bone metabolism. The purpose of the present study was to examine the occurrence of ARONJ and its related factors among patients with a history of antiresorptive therapy undergoing tooth extraction using preventive protocols at a Swiss university clinic. Data were retrospectively pooled from health records of patients having received a surgical tooth extraction between January 2015 and April 2020 in the Clinic of Cranio-Maxillofacial and Oral surgery, University of Zurich. A total of 970 patients received an extraction with flap elevation or wound closure during this period. A total of 104 patients could be included in the study. Furthermore, variables including age, gender, smoking, risk profile, choice, indication and duration of antiresorptive therapy, number of extractions, extraction site, surgical technique, choice and duration of antibiotics as well as the presence of postoperative inflammatory complications were assessed. Overall, 4 patients developed ARONJ (incidence of 3.8%) after tooth extraction at the same location, without previous signs of osteonecrosis. Preventive methods included predominantly primary wound closure using a full thickness mucoperiosteal flap and prolonged perioperative antibiotic prophylaxis. In accordance with current literature, the applied protocol showed a reliable outcome in preventing ARONJ when a tooth extraction is required.
