Influence of General Anesthesia on Impulsivity and Learning Ability-Experimental Study

DOI: 10.1515/amma-2016-0045

Objective: To investigate the effect of anesthesia on rats’ ability of learning and over their impulsivity.
Material and Methods: We studied eight Wistar adult male rats, test and drug naive subjects. Animals were separated in two groups, group A and B with four members each. Group A included the anesthetized animals. The combination of ketamine, xylazine and piplophen in 2ml/kg body weight dosage was used and testing was done 24 hours after anesthesia. Group B was taken as control. The study was conducted using the ”Delay discounting” apparatus. Experiments assessing impulsive behavior were conducted using automated operant chambers, equipped with two nose-poke holes (holes where pellets of food were released). Rat’s answer was considered touching the nose-poke hole. One answer was rewarded with pellets of food of 45 mg each (small reward), while another hole released five pellets of 45 mg each (high reward). Both types of rewards were presented immediately after rat’s answer and were followed for a period of 25 seconds timeout. During the training phase, rats were placed in operant chambers 30 minutes per day, 5 consecutive days. The growing percent of preference for greater reward indicates learning.For the testing phase the procedure was similar, but a delay was introduced before the release of the big reward. During this phase, the preference for higher reward was indicative for non-impulsive behaviour.
Results: The results didn’t show significant statistically differences between the two groups.
Conclusions: Anesthesia had no effect on learning ability nor on impulsivity.

Metastatic Prostate Cancer with Highest Reported PSA Level

DOI: 10.1515/amma-2016-0044

Introduction: Prostate cancer is the sixth most common cancer in the world, the second most common cancer among men, and the most common cancer in men in Europe. Metastatic prostate cancer among young patients represents the rarest of the newly diagnosed prostate cancer, with few reports of cases with a longer survival.
Case presentation: We present the case of a 59 year-old male who was referred with back pain over the last month. Digital rectal examination highlighted an enlarged and totally indurated prostate of 4×4.5 cm, while abdomino-pelvic X-rays showed osteoblastic metastases in the spine and pelvis bones. Laboratory examinations revealed a Prostate Specific Antigen level of 7941 ng/ml. Prostate biopsy histology showed a bilateral prostate cancer with a Gleason score of 8. Androgen deprivation therapy and daily administration of biphosphonates were prescribed. After two years of treatment, the Prostate Specific Antigen level decreases to 8 ng/ml.
Conclusions: We reported the highest Prostate Specific Antigen level in a patient under 60 years old with metastatic prostate cancer. Prostate cancer remains an important public health problem due to the aggressiveness of the disease and advanced stage upon diagnosis. Prostate Specific Antigen is mandatory to evaluate, to have a reference level in order to prevent metastatic prostate cancer in young patients at diagnosis.

DOI: 10.1515/amma-2016-0040

Insulin-dependent diabetes mellitus (IDDM) is a chronic disease with high incidence, especially in children, and for a better outcome the individual case management is required. The patient and his family can experience different levels of anxiety, with negative effects on disease evolution and prognosis.
Objectives: identify relevant factors which influence the case management of children with IDDM. The implementation of the results of this study will help to elaborate an efficient method of intervention for improving the treatment adherence and obtaining a better outcome of IDDM in children.
Methods: A semi-structured interview was done individually to 10 experts in diabetes for collecting their opinion concerning relevant factors that may influence treatment adherence and what are the characteristics of an efficient method of intervention.
Results: Majority of experts considered that the main factor which influences the outcome is doctor-patient relationship. The need of child, to feel that it is understood and protected, was considered that can directly motivate a better self-management and a good outcome. The increase of importance of individual resources of children with IDDM and accent on the quality of life of those children could be considered a starting point for creating a psychological clinic intervention in this field. The results were compared with scientific literature data.
Conclusions: understanding of the causes which have interfered negatively with therapeutic plan is a starting point for develop a clinical – psychological protocol for children with IDDM.

Maternal Knowledge, Attitudes and Practices Regarding Dietary Fats

DOI: 10.1515/amma-2016-0043

Objective: The purpose of the study was to assess the knowledge, attitudes, and behavior regarding dietary fats among mothers in Romania.
Material and methods: A sample of 305 mothers from Romania were included in a cross-sectional observational study. The online questionnaire addressed their knowledge, attitudes, and practices regarding the dietary fats used in their children’s diet. The frequencies and proportions of the collected variables were calculated based on respondents’ answers.
Results: While almost all the respondents (94.8%) believed that mothers are supposed to know the difference between saturated and unsaturated fats, only less than half of them (39.7%) stated that they know the difference. As far as the types of margarine, although more than half of the respondents (64.7%) believed that mothers should be able to discriminate between the hydrogenated and interesterified margarine, only 11.5% claimed that they are able to discern between them. The actual ability to identify foods rich in saturated fats varied in a great degree from item to item. More common dietary fats such as sunflower oil, corn oil, and lard, were more frequently identified than less common dietary fats such as coconut oil and palm oil. Only 16.4% of the mothers were able to correctly differentiate hydrogenated from interesterified margarine. The most frequently used spreadable fat used in the children’s diet was butter and the most frequently used cooking fats were sunflower oil, olive oil, and butter.
Conclusion: The results of this study might be informative in the development of maternal nutrition education programs.

A Rare Chromosomal Disorder – 14q Interstitial Deletion Syndrome

DOI: 10.1515/amma-2016-0041

Introduction: Interstitial deletions of the long arm of chromosome 14q (OMIM 613457) are very rare conditions.
Case presentation: We present a 3-month-old male patient with dysmorphic features and congenital heart defect associated with a small interstitial deletion of chromosome 14q, identified by cytogenetic analysis as 46,XY,del(14)(q11q12). Dysmorphic features included microcephaly, broad nasal bridge, micrognathia, large and poorly folded auricular lobes and long digits. He also present rectus abdominis diastasis and umbilical hernia. The cranial computer tomography showed partial agenesis of the corpus callosum and ventriculomegaly.
Conclusions: Cytogenetic analysis or molecular techniques are necessary to establish the correct diagnosis in patients with multiple congenital anomalies in association with proximal or distal interstitial 14q deletion.

Left Sided Gallbladder – Case Report

DOI: 10.1515/amma-2016-0042

Left sided gallbladder is a rare anomaly that is often associated with other abnormal anatomy in the hepatobiliary system. One left positioned gallbladder was found in a consecutive series of 3290 patients undergoing laparoscopic cholecystectomy for gallstone disease in the Mure County Emergency Hospital’s 2nd Surgery Clinic between 2005 and 2015, a prevalence of 0.03 per cent. In case of left sided gallbladder the cystic artery always crosses in front of the common bile duct from right to left. The cystic duct may open on the left or right side of the common hepatic duct. Anterograde cholecystectomy is the best choice for precise exploration of the cystic duct and cystic artery.

The Value of a Simplified Lung Ultrasound Protocol in the Pre-Discharge Evaluation of Patients Hospitalized with Acute Heart Failure

DOI: 10.1515/amma-2016-0039

Optimal timing of hospital discharge in patient with acute heart failure (AHF) is an important factor of preventing rehospitalizations.
Aim. To evaluate the value of a simplified lung ultrasound (LUS) protocol in assessing pre-discharge status of patients with AHF, correlating the US findings with the values of NT-proBNP levels.
Methods. 24 patients (18 men, 6 women, mean age 68,2 years) hospitalized with acute heart failure underwent LUS examination in the afternoon of the day before hospital discharge, applying a simplified LUS protocol, using three basal examination areas on the right side (anterior, lateral and posterior) and two basal examination areas on the left side (lateral and posterior). The LUS score was represented by the sum of B lines. In the next morning the value of NT-proBNP was also determined. The correlation between LUS findings and NT-proBNP values was analyzed using Fisher`s exact test (significant if alpha<0,05).
Results. 6 patients had <15 B lines, 16 patients had >15 B lines and 2 patients had pleural effusion on LUS, while 16 patients had the value of NT-proBNP >1000pg/ml at discharge. The results of LUS examination correlated significantly (p=0.0013) with the NT-proBNP values – only one patient not having increased NT-proBNP in the group with >15 B lines.
Conclusions. Despite a relatively good clinical status, the majority of patients had high NT-proBNP values at the time of hospital discharge. LUS proved to be a useful tool in identifying patients with subclinical congestion reflected also by the high NT-proBNP levels. These patients may need a prolongation of hospitalization and/or a more careful follow-up to prevent early readmission.

Predictors of Postoperative Outcome in Patients with Lower Limb Surgical Revascularization

DOI: 10.1515/amma-2016-0037

Objective: In patients with critical limb ischemia who undergone revascularization procedures, the assessment of risk factors that may affect the postoperative outcome is of great importance. The main objective in this study is to assess the utility of two specific risk scores, the Finnvasc score and the modified Prevent III score.
Methods: We evaluated the applicability of these two risk scores in 150 patients who undergone an unilateral infrainguinal surgical revascularization procedure. The receiver operating characteristic curve analysis was used to estimate the predictive value of the scoring methods. A comparison between the risk scores, determine the areas under the curve. Medium-term prediction ability was analyzed for both scoring methods.
Results: The area under the curve of Finnvasc score for predicting amputation was 0.739 (95%CI:0.661-0.807) and of the modified PIII score 0.713 (95%CI:0.633-0.784); for restenosis we obtained 0.528 (95%CI:0.444-0.611), respectively 0.529 (95%CI:0.445-0.612) and for thrombosis 0.628 (95%CI:0.544-0.706) and 0.556 (95%CI:0.472-0.638), demonstrating that the Finnvasc score performs better in overall prediction. Heart failure is a strong independent predictor of amputation (p=0.0001, OR=26.90; 95%CI:5.81-124.2), restenosis (p=0.0003, OR=4.80; 95%CI:1.96-11.8) and mortality (p=0.01, OR=7.16; 95%CI:1.33-38.52).
Conclusions: The accuracy of the two risk scoring methods in predicting the medium-term outcome of patients undergoing surgical infrainguinal revascularization is acceptable. The Finnvasc score is easier to be applied to the characteristics of our patients.

Prodrug Strategy in Drug Development

DOI: 10.1515/amma-2016-0032

Prodrugs are chemically modified derivatives introduced in therapy due to their advantageous physico-chemical properties (greater stability, improved solubility, increased permeability), used in inactive form. Biological effect is exerted by the active derivatives formed in organism through chemical transformation (biotransformation). Currently, 10% of pharmaceutical products are used as prodrugs, nearly half of them being converted to active form by hydrolysis, mainly by ester hydrolysis. The use of prodrugs aims to improve the bioavailability of compounds in order to resolve some unfavorable characteristics and to reduce first-pass metabolism. Other objectives are to increase drug absorption, to extend duration of action or to achieve a better tissue/organ selective transport in case of non-oral drug delivery forms. Prodrugs can be characterized by chemical structure, activation mechanism or through the presence of certain functional groups suitable for their preparation. Currently we distinguish in therapy traditional prodrugs prepared by chemical derivatisation, bioprecursors and targeted delivery systems. The present article is a review regarding the introduction and applications of prodrug design in various areas of drug development.
