Menstruation begins at puberty and marks a woman's ability to bear children, although other health factors may limit this capacity. This event is so natural and natural that it is certain that all normal women will experience this process. However, in reality many women experience menstrual problems, one of which is menstrual pain (dysmenorrhea) (Admin, 2008). The research was conducted at Panei Tongah Public Middle School 1, Simalungun Regency, on 139 respondents. There is a relationship between knowledge and the effect of using menstrual pain relievers at SMP Negeri 1 Panci Tongah, Simalungun Regency, with the P-Value of 0.001 0.05. There is no relationship between attitudes towards the effect of using menstrual pain relievers at Panei Tongah 1 Public Middle School, Simalungun Regency, where the value obtained is greater than the expected value (P Value 0.250 0.05). There is a relationship between action and the effect of using menstrual pain relievers at Panei Tongah 1 Public Middle School, Simalungun Regency. From the results of the Chi-square test, the P-Value is 0.001 0.05, so the hypothesis is accepted. It is hoped that young women will pay more attention to the effects of excessive use of pain relievers because this can be bad for health. It is hoped that the school will work closely with health workers to conduct health education in schools, especially for young girls.

Diarrhea is a condition in which there is an imbalance in absorption, secretion of water and electrolytes, resulting in a frequency disorder of defecation more than 3 times a day with liquid or semi-solid stools, with or without mucus or blood. Diarrheal disease is still a global problem with a high degree of morbidity and mortality in various countries, especially in developing countries, and is one of the main causes of high child morbidity and mortality in the world. This study aims to determine the profile and rationality of using diarrhea drugs in pediatric patients at the Dolat Rayat Health Center, Karo Regency. This research was conducted using a retrospective descriptive method. The results of the study from the Dolat Rayat Health Center in Karo Regency showed that of the 235 patients who suffered from diarrhea the most were men (63-83%) and at the age of 2 years old infants (48.51%) with an average per patient of 1.28 drug items. The most widely used type of diarrhea drug was zinc (62.67%) in the form of syrup (54.67%). The rationality for using diarrhea medicines based on the 2011 Indonesian Ministry of Health guidelines includes the criteria for right indication (100%), right drug (100%), right patient (99.15%), and right dose (96.17%). Most of the use of diarrhea drugs in pediatric patients at the Dolat Rayat Health Center in Karo Regency is rational.

If necessary, a special officer is appointed who is directly responsible for the implementation of IMD administration to newborns. It is hoped that in the teaching and learning process both in the classroom and in the laboratory the administration of IMD can be mastered by every student. This research can be used as evidence based in conducting research with the same variables or with several variables related to the provision of Early Breastfeeding Initiation (IMD).

Hypertension is a condition in which blood pressure increases above (≥140/90 mmHg). The prevalence in Indonesia is 32.2% and only 24.2% of these hypertensive patients are diagnosed and receiving treatment. Diabetes mellitus (DM) is a metabolic disorder characterized by glucose levels exceeding normal values ​​or perglycemia (≥200 mg/dl). to evaluate the cost-effectiveness of antihypertensive and anti-diabetic in patients who are hospitalized at Efarina Etaham Berastagi Hospital, Karo. This research is non-experimental using data taken from patient medical records retrospectively for the period January-June 2017. The analytical method used is Cost Effectiveness Analysis (CEA). The Cost Effectiveness Average Ratio (CEA Ratio) and Incremental Cost Effectiveness Ratio (ICER) methods were used to analyze the most cost-effective antihypertensives and antidiabetics. The results of this study showed that the hypertension therapy regimens used were amlodipine, captropil, valsartan, amlodipine + captropil, amlodipine + valsartan, captorpil + valsartan, and amlodipine + captorpil + valsartan. In the anti-diabetic therapy regimen used are insulin analogues, metmorphine and insulin analogues + metmorphine. The most cost-effective antihypertensive based on the CEA and ICER is amdolpine + captropil and the most cost-effective diabetic liver based on the CEA and ICER is metmorphine. amlodipine + captropil, amlodipine + valsartan, captorpil + valsartan, and amlodipine + captorpil + valsartan. In the anti-diabetic therapy regimen used are insulin analogues, metmorphine and insulin analogues + metmorphine. The most cost-effective antihypertensive based on the CEA and ICER is amdolpine + captropil and the most cost-effective diabetic liver based on the CEA and ICER is metmorphine. amlodipine + captropil, amlodipine + valsartan, captorpil + valsartan, and amlodipine + captorpil + valsartan. In the anti-diabetic therapy regimen used are insulin analogues, metmorphine and insulin analogues + metmorphine. The most cost-effective antihypertensive based on the CEA and ICER is amdolpine + captropil and the most cost-effective diabetic liver based on the CEA and ICER is metmorphine.
