Summary Aim of the study was to find out wether there is a common stop of growth of mandibular bone, so that no individual determination of the optimal time for surgery in patients with asymmetric mandibular bone growth is needed. As there are no epiphyseal plates in the mandibular bone, stop of growth cannot be determined on X-ray films. Methods: Bone scans of 731 patients [687 patients (324 male, 363 female) under 39 y for exact determination of end of growth and 44 (21 male, 23 female) patients over 40 y for evaluation of nongrowth dependant differences in tracer uptake] were reviewed for the study. All the patients were examined 3 hours after injection of 99mTc-DPD. Tracer uptake was measured by region of interest technique in different points of the mandibular bone and in several epiphyseal plates of extremities. Results: Tracer uptake in different epiphyseal plates of the extremities shows strong variation with age and good correlation with reported data of bone growth and closure of the epiphyseal plates. The relative maximum of bone activity is smaller in mandibular bone than in epiphyseal plates, which show well defined peaks, ending at 15-18 years in females and at 18-21 years in males. In contrast, mandibular bone shows no well defined end of growing but a gradually reduction of bone activity which remains higher than bone activity in epiphyseal plates over several years. Conclusion: No well defined end of growth of mandibular bone exists. The optimal age for surgery of asymmetric mandibular bone growth is not before the middle of the third decade of life, bone scans performed earlier for determination of bone growth can be omitted. Bone scans performed at the middle of the third decade of life help to optimize the time of surgical intervention.

Ripening Of The Cervix

The question of the prevention of pathologies of the labor is currently very important, the answer to them has become the favored formation of «dominants of delivery», choice of the optimal time to delivery, effective and safe method of induction, that promotes the promptness of the female organism and ripening of the cervix, as well as the timely identification and correction of pathological prelмmмnary period. In a review article describes the modern approaches and methods of preventing the pathology of labor activity, presented by the authors ‘ own experience regarding the use of prostaglandins, non-steroidal anti-inflammatory drugs, individual approach to the management of perinatal risk. Key words: childbirth, prevention, induction, prostaglandin, non-steroidal anti-inflammatory drugs.

Time Required

The Embung Bengawan Project in Tarakan City has several jobs requiring heavy equipment including mechanical soil removal activities. Activity of mechanical soil movement is a series in work of loading and transportation equipment. In order to achieve optimal mechanical soil removal targets, it is necessary to know the performance of the machine during the mechanical soil removal process. The optimization of production is the way to obtain production that is in accordance with optimal conditions of mechanical devices. This paper discusses the optimization of dump truck queue time and the number of dump trucks. Performance calculation tool using the method of production capacity of the tool, and calculate the optimal queue using the Queue Model method. Calculation using queuing model method obtained by result of time required by 3 excavator unit and with combined amount of dump truck will give result of cost equal to Rp 48,097,711 / day, and dump truck waiting time in queue to 1 minute. Then the optimal time is obtained by operating 3 units of excavators with a cost difference of Rp 3,572,826 / day from the real condition of the field that operates 2 excavator units

One of the most challenging questions to answer in pulmonary arterial hypertension (PAH) is: “When is the optimal time to proceed with lung transplantation?” The current lung allocation scoring (LAS) system prioritizes donor organ resources based on severity of illness. Factors used to assign LAS do not account for known predictors of outcome for PAH patients—including determinants of right ventricular (RV) function. It has been recognized that the system places PAH patients at a distinct disadvantage, and concerted efforts are being made to correct this by considering variables that reflect RV function, specifically mean right atrial pressure (mRAP) and cardiac index (CI).

Asking Questions

BACKGROUND Current workflow in GYN triage has medical students interviewing patients after triage by nursing staff. The optimal time to initiate patient contact is unclear. This confusion has led to duplication of questions to patients, interruptions for nurses and fewer patient encounters for students. OBJECTIVE Determine if a restaurant-style buzzer can streamline workflow in gynecology (GYN) triage. METHODS A Plan-Do-Study-Act approach was used. Stakeholders were medical students, nurses, Nurse Practitioners and physicians. Factors contributing to workflow slowdown: students re-asking questions of patients, interruption of nursing staff, confusion about optimal patient flow. The net result was fewer interviews completed by students. The project was introduced during clerkship orientation. Buzzers were provided on weeks 1, 3, 5 of the rotation. Weeks 2, 4, 6 no buzzers were provided as an internal control. After each clerkship, students received a survey assessing key areas of waste and workflow disruption. A focus group with ten nurses was also conducted. RESULTS From February-July 2019, 30/45 surveys were completed (66%) 1. Very difficult/difficult to know when to begin the encounter: 90% without; 21.4% with buzzer p<.001 2. Students re-asking questions: very often/often 96.7% without; 14.8% with buzzer p<.001 3. Nursing staff interruptions: 76.7% very often/often without; 18.5% with buzzer p<.001 4. The odds of interviewing 5 or more patients per shift are ~10X greater using the buzzer χ²=14.2; p<.001 CONCLUSIONS The 10 nurses interviewed unanimously favored the use of the buzzer. Introduction of a simple, low-cost restaurant-style buzzer improved triage work-flow, student and nursing experience.
