Published: August 2020

Background: Short stature (SS) is a common pediatric problem. The goal of the evaluation of a child with SS is to identify the subset of children with pathologic causes so that appropriate timely intervention can be made. Aim: The aim of the study was to study the clinical, epidemiological, and etiological profile of SS at a tertiary hospital of north India. Materials and Methods: This was an observational analytical study and was conducted in the department of pediatrics, over a period of 1 year (October 2016– September 2017). A total of 100 children aged 3–14 years, with height <?2SD below the mean height for age and sex, were studied. Clinical history, examination, and laboratory evaluations were done to assess the cause of SS and the data were analyzed using appropriate statistical methods. Results: About 55% were female and 45% were male. The causes of SS were found to befamilial SS (28%), celiac disease (17%), chronic diseases (15%), constitutional growth delay (12%), hypothyroidism (11%), small for gestational age babies with no catch-up growth (10%), use of corticosteroids (4%), and growth hormone deficiency (3%). Conclusion: Chronic systemic illnesses and malnutrition still form a major chunk in the etiological profile of SS in India. Celiac disease should be considered with a high index of suspicion as one of the etiologies of SS.

Published: August 2020

ACFTA or ASEAN-China Free Trade Area, also known as China-ASEAN Free Trade Area is an economic agreement to construct a free trade zone between 10 ASEAN member countries and China to eliminate various tariff and non-tariff barriers. All of ASEAN members’ leaders and China’s leader signed the ACFTA on November 5, 2002 in Phnom Penh, Cambodia which latter came into effect on January 1, 2010. Since then, it was recorded in 2016 that the total trade between ASEAN and China has reached to US$ 475 billion, thus making China as ASEAN’s largest trading partner while ASEAN serves as China’s third largest trading partner. This means that China’s export to ASEAN is more than ASEAN’s export to China. It could be seen that the free trade area has benefitted China more than it has benefit ASEAN. This paper aims to provide brief explanation on how China is able to benefit more on the trade agreement. Using a descriptive method of analysis, combined with expansionism and multilateral diplomacy concepts, it can be found that China is able to utilize various means to maximize its benefit in the ACFTA scope of agreement. Through the ACFTA, China has managed to master trade routes, break trade barriers, invest more, deepen economic cooperation contracts and master production skills in manufacturing all across ASEAN member countries. All of these efforts are made possible by China’s favourable multilateral diplomacy instruments in the ACFTA.

This study discusses managerial decision making regarding buying or rental (leasing) options in the procurement of official vehicles. This study aims to analyze the most appropriate options between buying or rental (leasing) for the procurement of official vehicles so that they can be input in making decisions regarding procurement of official vehicles. There are differences of opinion regarding the most efficient method of buying or (leasing) rental options in several government agencies so a study is needed to choose the most appropriate method. Differences in decision making related to procurement of official vehicles can have an impact on budget efficiency. This research is a qualitative research with a case study approach. Case studies were conducted at the Secretariat General of the Ministry of Finance. The data used in this study include primary data in the form of interviews with research resource person and secondary data in the form of regulations and reports related to official vehicles. The method of analyzing data from interviews uses the Miles and Huberman method which consists of 3 stages, namely data reduction, data display, and conclusion drawing. Secondary data were analyzed by calculating the net present value of the total cost of ownership. The results of this study indicate that under normal conditions, buying options are relatively more efficient compared to (leasing) rental options in the procurement of official vehicles. However, (leasing) rental options can be applied under certain conditions.

Published: August 2020

Background: Premature rupture of membranes (PROM) is a common obstetric complication. Knowledge of etiopathogenesis, diagnosis, complications & management of PROM has increased due to extensive research in the recent past. Yet, there is no unanimous opinion regarding optimum management of PROM. The aim of the study was to observe the patients during labor and compare the latent period, duration of first stage of labor, modes of deliveries and the use of oxytocin and its outcome in PROM cases with controls.
Materials and methods: In this study, the definition of PROM used is – rupture of fetal membranes before the onset of true labor pain. The minimum gestational age was taken to be 28 weeks. Diagnosis of PROM was mainly clinical. A cohort study was conducted in the Dept. of Obs & Gynae of KPL Medical College & Hospital, Kolkata on 100 cases of PROM and 100 cases of comparison group, over a period of one year.
Results: It was observed that onset of labor was more rapid with increasing gestational age, use of oxytocin for induction & augmentation of labor & operative deliveries were higher in PROM cases.
Conclusion: Individualized management of PROM cases depending on the gestational age and risk of complications is the best way to achieve a good feto-maternal outcome.
