Background: Ampicillin in trihydrate form is a b-lactamine antibiotic frequently used in therapy as suspensions and capsules. Because of the low stability only dry suspensions are sold, and also the low stability in acidic environment is source of unwanted side effects and bioavailability variations.
Aim: Our goal was to stabilize ampicillin so that a better stability can be obtained both in water suspensions and acidic solutions. This way misuse due to faulty preparation, side effects and bioavailability problems can be avoided.
Methods: In order to assess the changes in the ampicillin concentration high performance liquid chromatography (HPLC) and thin layer chromatography (TLC) methods have been used.
Results: None of the tried excipients improved stability of ampicillin suspensions. In contrast cyclodextrins and magnesium salts of glutamic and aspartic acid greatly improved the stability of ampicillin acidic solutions. In high amounts cyclodextrins also change the decomposition kinetic of ampicillin, which is usually a first order kinetic process.
Conclusions: Cyclodextrins and magnesium salts of glutamic and aspartic acid have the potential to be used in ampicillin containing formulations in order to increase its stability, bioavailability and to reduce adverse effects.

Background: The success of treatment of a young permanent tooth with pulp necrosis appropriate each stage of development depends primarily on the complete sterilization of infected root canals using specific endodontics drugs capable of destroying pathogenic microorganisms, especially obligate and facultative anaerobic bacteria.
Aim: The purpose of this research is to evaluate the antimicrobial effect of the three most used intraradicular substances, respectively mineral trioxide aggregate, calcium hydroxide and calcium hydroxide with iodoform on anaerobic bacteria isolated from infected root canals and also on pure bacterial species, namely Staphylococcus Aureus , Enterococcus Faecalis and Candida Albicans, cultures coming from the collection of the microbiology laboratory.
Material and methods: Anaerobic species grown on specific culture medium were prepared in the form of bacterial suspension using standardized system of 0, 5 McFarland turbidity diluted by half. The three drugs tested were used in different concentration and to each of them was added 1 ml of bacterial suspension obtained previously. From each sample obtained were made insemination on specific anaerobic medium and interpretation of results was made by comparing the number of bacterial colonies grown.
Results: Following this study MTA has failed to demonstrate superiority over calcium hydroxide in terms of antibacterial properties results showing that each substance tested has elective action on bacterial species.
Conclusion: All endodontic materials tested have shown antimicrobial properties able to effectively sterilize infected root canals but they compared different actions on bacterial species taken to study depending on the amount of active substance tested.

Hepatocellular carcinoma represents 5 % of the cases of death in the world. The recent epidemiological data show a major increase of its incidence in the western countries and USA, the explanation being through the growth in the incidence of viral hepatopathies, especially with hepatitis C virus. Of the patients diagnosed with hepatocarcinoma, 70 % benefit from palliative treatment only. The curative treatment in the case of hepatocarcinoma includes surgical resection, liver transplant, radiofrequency. Magnetic Resonance Imaging-guided percutaneous cryotherapy, the method in progress of evaluation, seems to give spectacular results in the case of small size, non resectable situated very close to the hepatic hylum. The evolution of a patient with viral cyrrhosis C complicated with a hepatocarcinoma and the problems related to hepatocarcinoma treatment while waiting for liver transplantation was the object of an analysis that allowed the emphasis of the lack of tumoral progress and the reduction of tumoral volume until its disappearing from an imagistic point of view.

Background: Depending on intensity, anxiety can have an adapting and mobilizing role, or it can represent a serious risk.
Aim: To examine the prevalence of anxiety symptoms for those who work in a clinic of psychiatry.
Material and method: Group consists of 35 persons who work in the Acute Psychiatric Clinic II – Targu Mures. Anxiety was measured as a current emotional state and as a trait by Spielberger’s State-Trait Anxiety Inventory (STAI).
Results: Applying Spielberger’s Inventory 33.3% of the female and 28.5% of the male might be suspected of suffering from significant anxiety symptoms as a state. Also the subject’s predisposition to anxiety as a trait of the subject’s personality is important, 24% of female and 43% of men had levels of anxiety over 60% compared with standards.
Conclusions: An important number of people who work in psychiatry have high scores of anxiety. Further studies are needed to clarify to what extent this relates to a high prevalence of anxiety disorders.

Background: The number of lymph nodes evaluated may be a measure of quality in colon cancer care and appears to be inadequate in most patients treated for colon cancer. We performed a systematic review of the evidence for the association between lymph node evaluation and oncologic outcomes in patients with colon cancer.
Aim: The adequate lymph node evaluation for cancer involvement, prognosis and adequate treatment of patients with colon cancer.
Method: It included information about diagnosis, patient age at diagnosis, the surgical procedure that was performed, anatomic location of the cancer, histology, tumor size, number of LN identified, number of LN positive for cancer, general stage (local, regional or to distance, TNM stage /A7CC). Rectal cancer was excluded. We analyzed data from the cancer registry of 1st Surgical Clinic of Sibiu including 287 patients with colon cancer. This registry includes follow-up information from 1998 to 2009. Identification of ≥12 LN (lymph nodes) in resected colon cancer specimens has been considered as a quality indicator. In patients with resected colorectal cancer, LN the involvement has particular importance for patient prognosis and adjuvant therapy.
Results: The average number of LN identified increased from 6±3 during 1998–2003, to 14±5 during 2003–2009. The proportion of patients diagnosed with positive LN increased from 31.6% during 1998–2003 to 37% during 2003–2009. No significant change in the proportion of patients diagnosed with just one positive LN (10% versus 10.6%) was observed.
Conclusion: The results suggest a relationship between the survival and identification of 12+ LN for stage I or II, considering the disease.

Background: The incidence of adenocarcinoma of the esophagus has dramatically increased during the last 2 decades and so has the incidence of Barrett’s esophagus, one of the most important risk factors for esophageal adenocarcinoma.
Aim: The aim of this study was to determine whether infection with Helicobacter pylori is associated with a lower risk of Barrett’s esophagus development in our area, and if there is a direct correlation between hiatal hernia and Barrett’s esophagus.
Material and method: We studied a series of 4359 patients who were investigated by upper endoscopy in the Gastroenterology and Endoscopy Unit of Targu Mures County Clinical Emergency Hospital between the 1st of January 2009 and 31st of December 2009. Barrett’s esophagus was defined as the presence of specialized columnar epithelium with goblet cells in the esophagus. We compared the patients with Barrett’s esophagus with a similar serie with patients without reflux disease.
Results: In 33 patients a diagnosis of Barrett’s esophagus was established. There was a strong predominance of males. The mean age at diagnosis was 64.18 years. Helicobacter pylori was present in 17 cases (51.51%) in the control patients compared to 42.42% in patients with Barrett’s esophagus (p 0.622, Odds Ratio: 0.69 95% CI: 0.26-1.83). Hiatal hernia was present in patients with Barrett’s esophagus in 21 cases (63.63%), and in patients without reflux disease only in 5 cases (15.15%) (p<0.001, Odds Ratio: 9.8: 95% CI: 2.99-32.18).
Conclusions: A significant correlation between hiatal hernia and Barrett’s esophagus was demonstrated in our study (p<0.001).
