INTRODUCTION: This prospective, observational study evaluated transanal dearterialization (THD) efficacy and safety in grade 2-4 hemorrhoids (HD). METHODS: THD was performed under sedation-locoregional anesthesia in 402 outpatients. Patients had follow-up evaluation 3 days, 2 weeks, 1, 6 and 12 months postoperatively. Postoperative complications and recurrence of symptoms at 12 months were analyzed. The relationship between the learning curve and the number of postoperative complications was studied. RESULTS: Mean patient age was 46.4 (range 20-85) years. A total of 268 patients (66.6%) were male. Sixteen patients (4.0%) had grade 2 HD, 210 (52.2%) had grade 3 and 176 (43.8%) had grade 4 HD. Surgery lasted 23 (17-34) min. A total of 67 patients had complications: bleeding in 10 patients (2.5%), hemorrhoidal thromboses in 10 (2.5%), perianal fistulas in 5 (1.2%), fissures in 14 (3.5%), urinary retention in 3 (0.8%), residual prolapse in 19 (4.7%), severe anal pain in 3 (0.8%), and perianal abscess in 3 patients (0.8%). Recurrent HD occurred in 6.3% (1/ 16) of grade 2 HD patients, 5.8% (12/210) of grade 3 patients and 9.7% (17/176) of grade 4 patients. Twelve months after THD, bleeding was controlled in 363 patients (90.5%), prolapse was controlled in 391 (97.3%) and pain markedly improved in 390 patients (97%). CONCLUSION: THD appears safe and effective for grade 2-4 HD, and the number of complications decreased with increasing surgeon experience. THD advantages include mild pain, fast recovery, early return to daily activities and low incidence of complications

Catheter-associated urinary tract infection in a surgical intensive care unit.

BACKGROUND/AIM: Because patients in intensive care units usully have an urinary catheter, the risk of urinary tract infection for these patients is higher than in other patients. The aim of this study was to identify risk factors and causative microrganisms in patients with catheter-associated urinary tract infection (CAUTI) in the Surgical Intensive Care Unit (SICU) during a 6-year period. METHODS: All data were collected during prospective surveillance conducted from 2006 to 2011 in the SICU, Military Medical Academy, Belgrade, Serbia. This case control study was performed in patients with nosocomial infections recorded during surveillance. The cases with CAUTIs were identified using the definition of the Center for Disease Control and Prevention. The control group consisted of patients with other nosocomial infections who did not fulfill criteria for CAUTIs according to case definition. Results. We surveyed 1,369 patients representing 13,761 patient days. There were a total of 226 patients with nosocomial infections in the SICU. Of these patients, 64 had CAUTIs as defined in this study, and 162 met the criteria for the control group. Multivariate logistic regression analysis identified two risk factors independently associated to CAUTIs: the duration of having an indwelling catheter (OR = 1.014; 95% CI 1.005-1.024; p = 0.003) and female gender (OR = 2.377; 95% CI 1.278-4.421; p = 0.006). Overall 71 pathogens were isolated from the urine culture of 64 patients with CAUTIs. Candida spp. (28.2%), Pseudomonas aeruginosa (18.3%) and Klebsiella spp. (15.5%) were the most frequently isolated microorganisms. CONCLUSIONS: The risk factors and causative microrganisms considering CAUTIs in the SICU must be considered in of planning CAUTIs prevention in this setting.

Synchronous gastric and colonic cancer--A case report.

INTRODUCTION: Synchronous gastric and colorectal cancer is present in 4% of cases, commonly as additional finding. This is the case of invasive, synchronous gastric and sigmoid colon cancer. CASE REPORT: A 63-years-old male patient admitted to our institution complaining on pains in epigastrium, vomiting, rapid weight loss and occasional constipation. Using the method of esophagogastroduodenoscopy (EGD) the presence of ulcero-infiltrative tumor of gastric fundus was verified, and colonoscopy revealed stenosing tumor of sigmoid colon. Undergoing a multislice computed tomography (MSCI) of the thorax and the abdomen the changes on the patient's right lung appeared, while video-assisted thoracoscopy (VATS) and biopsy of the right lung excluded malignant dissemination. A total gastrectomy with omentectomy, splenectomy, D2 lymphadenectomy and typical left hemicolectomy were also performed. Histopathological examination verified invasive, diffuse gastric adenocarcinoma and invasive, tubular colon adenocarcinoma. The patient underwent systemic postoperative chemotherapy. Two years after the surgical procedure, the patient is alive, with no signs of recidivism. CONCLUSION: In patients with symptomatology which does not correspond to primary malignancy, just like in the presented case, additional diagnostics is required. Combined resection is adequate surgical procedure for synchronous gastric and colonic cancer.

Cytokine profile in severe Gram-positive and Gram-negative abdominal sepsis.

Sepsis is a principal cause of death in critical care units worldwide and consumes considerable healthcare resources. The aim of our study was to determine whether the early cytokine profile can discriminate between Gram-positive and Gram-negative bacteraemia (GPB and GNB, respectively) and to assess the prognostic value regarding outcome in critically ill patients with severe abdominal sepsis. The outcome measure was hospital mortality. Blood samples were obtained from 165 adult patients with confirmed severe abdominal sepsis. Levels of the proinflammatory mediators TNF-α, IL-8, IL-12 and IFN-γ and the anti-inflammatory mediators IL-1ra, IL-4, IL-10 and TGF-ß1 were determined and correlated with the nature of the bacteria isolated from the blood culture and outcome. The cytokine profile in our study indicated that the TNF-α levels were 2-fold, IL-8 were 3.3-fold, IFN-γ were 13-fold, IL-1ra were 1.05-fold, IL-4 were 1.4-fold and IL-10 were 1.83-fold higher in the GNB group compared with the GPB group. The TNF-α levels were 4.7-fold, IL-8 were 4.6-fold, IL-1ra were 1.5-fold and IL-10 were 3.3-fold higher in the non-survivors compared with the survivors.

Prognostic Value and Daily Trend of Interleukin-6, Neutrophil CD64 Expression, C-Reactive Protein and Lipopolysaccharide-Binding Protein in Critically Ill Patients: Reliable Predictors of Outcome or Not?

BACKGROUND: Severe sepsis and/or trauma complicated by multiple organ dysfunction syndrome are the leading causes of death in critically ill patients. The aim of this prospective single-centre study was to assess the prognostic value and daily trend of interleukin-6 (IL-6), neutrophil CD64 expression, C-reactive protein (CRP) and lipopolysaccharide-binding protein (LBP) regarding outcome in critically ill patients with severe trauma and/or severe sepsis. Outcome measure was hospital mortality. METHODS: One hundred and two critically ill patients admitted to the intensive care unit of a tertiary university hospital were enrolled in this prospective study. Blood samples were collected on admission (day 1), days 2 and 3. RESULTS: CD64 index was 1.6-fold higher on day 1 and 1.78-fold higher on day 2 in non-survivors (p<0.05). The area under the curve (AUC) for the CD64 index on day 1 for outcome was 0.727. At a cut-off level of 2.80 sensitivity was 75% and specificity was 65%. Patients with CD64 index level on day 1 higher than 2.80 had 2.4-fold higher probability of dying. Odds ratio is 2.40; 95% CI 0.60-9.67. CONCLUSIONS: CD64 index on day 1 is a fairly good predictor of outcome. AUCs for IL-6, CRP and LBP were < 0.55, suggesting these biomarkers failed to predict outcome.

Factors influencing antibiotic treatment cost and outcome in critically ill patients: a "real-life" study.

UNLABELLED: BACKGROUND/AIM. Critically ill patients are at very high risk of developing severe infections in intensive care units (ICUs). Procalcitonin (PCT) levels are eleveted in the circulation in patients with bacterial sepsis and PCT might be useful in guiding antibiotic treatment. The aim of this study was to estimate factors influencing patients survival and treatment cost in ICU with special emphasis on the impact of PCT serum levels use in guiding antimicrobial therapy. METHODS: The study was conducted from August 2010 to May 2012 in the Intensive Therapy Unit, Clinic of Anesthesiology and Intensive Therapy, Military Medical Academy (MMA), Belgrade, Serbia. All adult critically ill patients with sepsis and/or trauma admitted in the ICU were included in the study. This study included only the cost of antimicrobial therapy in the ICU and the cost for PCT analysis. We used prices valid in the MMA for the year 2012. PCT in serum was measured by homogeneous immunoassay on a Brahms Kryptor analyzer. RESULTS: A total of 102 patients were enrolled. The mean patients age was 55 ± 19 years and 61.8% of patients were male. The mean length of stay (LOS) in the ICU was 12 ± 21 days. There was a statistically significant difference (p < 0.001) between the sepsis and trauma group regarding outcome (higher mortality rate was in the sepsis group, particularly in the patients with peritonitis who were mostly women). The patients younger than 70 years had better chance of survival. LOS, the use of carbapenems and PCT-measurement influenced the cost of therapy in the ICU. CONCLUSIONS: The obtained results show that age, the diagnosis and gender were the main predictors of survival of critically ill patients in the ICU. The cost of ICU stay was dependent on LOS, use of carbapenems and PCT-measurement although the influence of these three factors on the outcome in the patients did not reach a statistical significance.

Combined spinal-epidural technique: single-space vs double distant space technique.

BACKGROUND/AIM: Several combined spinal-epidural (CSE) anesthesia techniques have been described. This study was designed to compare the single space ("needle-through-needle") technique (SST) and the double distant space technique (DDS) with regards to the time needed for the procedure, patient discomfort during the procedure and patient's preference technique. METHODS: This prospective, randomized single-blind study included 156 patients undergoing colorectal surgery under general anesthesia and CSE. All neuraxial blocks were performed before general anesthesia induction. DDS group of patients had thoracic epidural catheter placed at T6-7 or T7-8, followed by subarachnoid injection at the L2-3 interspace. The SST group of patients had a single injection using the needle-through-needle technique (Espocan needle) at L2-3. The epidural catheter was used for postoperative analgesia for 72 hours. Body habitus, spinal anatomy and spinal landmarks were assessed preoperatively. The number of epidural and spinal punctures, the feeling that the dura is perforated (dural perforation click) and the time needed to perform CSE were also recorded. Complications during epidural catheter placement and perioperative and postoperative epidural catheter function and patient preference for the anesthetic procedure were recorded. RESULTS: Epidural and subarachnoid spaces were successfully identified in all the patients. Duration of CSE procedure, the number of spinal punctures, dural click feeling and the effects of test dose did not differ between the groups. The patients in both groups (90% of DDS and 87% of SST) would choose CSE as preferred method in the future. The CSE procedure was painful for 16% of DDS vs 20% of SST patients. A significant correlation between time needed for CSE technique performance and body habitus (r = 0.338, p < 0.01), spinal landmarks (r = 0.452, p < 0.001) and anatomy (r = 0.265, p < 0.05) was found in the SST group. There was no correlation between the number of epidural/spinal punctures and epidural bacteriological findings. There was no correlation between the patients' choice of the CSE technique and the number of spinal punctures, duration of CSE procedure and epidural catheter stay. CONCLUSION: The two CSE techniques did not differ with regards to the procedure time and patient's preference. Procedure time correlated with body habitus, spinal landmarks and the anatomy in the SST group.

Immunoinflammatory response in critically ill patients: severe sepsis and/or trauma.

Immunoinflammatory response in critically ill patients is very complex. This review explores some of the new elements of immunoinflammatory response in severe sepsis, tumor necrosis factor-alpha in severe acute pancreatitis as a clinical example of immune response in sepsis, immune response in severe trauma with or without secondary sepsis, and genetic aspects of host immuno-inflammatory response to various insults in critically ill patients.

Immune response in severe infection: could life-saving drugs be potentially harmful?

Critically ill patients suffer a high rate of nosocomial infection with secondary sepsis being a common cause of death. Usage of antibiotics and catecholamines is often necessary, but it can compromise complex immune response to infection. This review explores influence of these life-saving drugs on host immune response to severe infection.

Comparison of analgesic effect of intrathecal morphine alone or in combination with bupivacaine and fentanyl in patients undergoing total gastrectomy: a prospective randomized, double blind clinical trial.

BACKGROUND/AIM: Combined spinal-epidural-general anesthesia has several advantages over general anesthesia alone. This study was designed to compare the efficacy of intrathecal (IT) morphine alone, or in combination with bupivacaine and fentanyl, as part of a combined spinal-epidural (CSE) analgesia, in patients undergoing elective total gastrectomy. METHODS: This prospective, randomized double-blind study included 60 patients undergoing total gastrectomy under general anesthesia and CSE. We compared the analgesic effect of lumbar IT morphine 300 microg (the group M, n = 20) vs morphine 300 .g + bupivacaine 2 mg (the group MB, n = 20) vs morphine 300 microg + bupivacaine 2 mg + fentanyl 25 pg (the group MBF, n = 20) given after thoracic epidural catheter placement (T6-7) but before general anesthesia induction. Pain visual analogue scale (VAS) at rest (R), with movement (M) and with cough (C), and the number of analgesia requests were assessed for 72 h and after epidural catheter removal. RESULTS: Compared to other groups, the MBF group required significantly fewer additional intra-operative epidural bupivacaine doses (p < 0.001), whereas the M group required significantly more supplemental intraoperative intravenous fentanyl, compared with the MBF (p = 0.022) and MB groups (p = 0.005). Postoperative pain relief was satisfactory in all the groups at all the time. VAS-R and VAS-M did not differ significantly among the groups. Compared to the M group, VAS-C scores 30 min postoperatively were significantly lower in the MBF (p = 0.029) and MB groups (p = 0.002). Duration of analgesia was longer in the MBF and MB groups, but the difference reached no significance. The number of supplemental analgesia requests was similar in all the groups in the first 12 h and during 72 h. Additional analgesia requests after epidural catheter removal were similar in all the groups, and side effects were infrequent. CONCLUSION: Compared to IT morphine alone, triple IT combination administered as part of CSE provided better intraoperative analgesia, but conferred no benefit with regards to postoperative analgesia.

Myocardial protection during elective coronary artery bypasses grafting by pretreatment with omega-3 polyunsaturated fatty acids.

BACKGROUND/AIM: Despite recent advances in coronary artery bypass grafting (CABG), cardioplegic cardiac arrest and cardiopulmonary bypass (CPB) are still associated with myocardial injury. Accordingly, the efforts have been made lately to improve the outcome of CPB by glucose-insulin-potassium, adenosine, Ca(2+)-channel antagonists, L-arginine, N-acetylcysteine, coenzyme Q10, diazoxide, Na+/H+ exchange inhibitors, but with an unequal results. Since omega-3 polyunsatutated fatty acids (PUFAs) have shown remarkable cardioprotection in preclinical researches, the aim of our study was to check their effects in prevention of ischemia reperfusion injury in patients with CPB. METHODS: This prospective, randomized, placebo-controlled study was performed with parallel groups. The patients undergoing elective CABG were randomized to receive preoperative intravenous omega-3 PUFAs infusion (n = 20) or the same volume of 0.9% saline solution infusion (n = 20). Blood samples were collected simultaneously from the radial artery and the coronary sinus before starting CPB and at 10, 20 and 30 min after the release of the aortic cross clamp. Lactate extraction/excretion and myocardial oxygen extraction were calculated and compared between the two groups. The levels of troponin I (TnT) and creatine kinase-myocardial band (CK-MB) were determined before starting CPB and 4 and 24 h postoperatively. RESULTS: Demographic and operative characteristics, including CPB and aortic cross-clamp time, were similar between the two groups of patients. The level of lactate extraction 10 and 20 min after aortic cross-clamp time has shown negative values in the control group, but positive values in the PUFAs group with statistically significant differences (-19.6% vs 7.9%; p < 0.0001 and -19.9% vs 8.2%; p < 0.0008, respectively). The level of lactate extraction 30 minutes after reperfusion was not statistically different between the two groups (6.9% vs 4.2%; p < 0.54). Oxygen extraction in the PUFAs group was statistically significantly higher compared to the control group after 10, 20 and 30 min of reperfusion (35.5% vs 50.4%, p < 0.0004; 25.8 % vs 48.7%, p < 0.0001 and 25.8% vs 45.6%, p < 0.0002, respectively). The level of TnT, 4 and 24 h after CPB, was significantly higher in the control group compared to PUFAs group, with statistically significant differences (11.4 vs 6.6, p < 0.009 and 12.7 vs 5.9, p < 0.008, respectively). The level of CK-MB, 4 h after CPB, was significantly higher in the control group compared to PUFAs group (61.9 vs 37.7, p < 0.008), but its level, 24 h after CPB, was not statistically different between the two groups (58.9 vs 40.6, p < 0.051). CONCLUSION: Treatment with omega-3 PUFAs administered preoperatively promoted early metabolic recovery of the heart after elective CABG and improved myocardial protection. This study showed that omega-3 emulsion should not be considered only as a nutritional supplement but also as a clinically safe and potent cardioprotective adjunct during CPB.

Effect of pretreatment with omega-3 polyunsaturated fatty acids (PUfas) on hematological parameters and platelets aggregation in patients during elective coronary artery bypass grafting.

BACKGROUND/AIM: [corrected] Using omega-3 polyunsaturated fatty acids (PUFAs) in coronary artery bypass graft surgery (CABG) could provide protection against ischemic-reperfusion damage, prevention of postoperative arrhyth mia and attenuation of inflammatory response. However, omega-3 PUFAs inhibit cyclooxygenase (and thus decrease the synthesis of thromboxane A2 from arachidonic acid in platelets), which leads to decreased platelet aggregation. In cardiac surgery it is necessary to achieve a balance between inhibition and full platelets function. It is as well as im portant to closely follow hematological parameters, im paired by CABG itself. Therefore, the aim of the study was to establish the effects of pretreatment with omega-PUFAs on hematological parameters and plateletes aggre gation in patients with elective CABG. METHODS: This prospective, randomized, placebo-controlled, single-center trial was performed on parallel groups. The patients (n = 40) undergoing elective CABG were randomized receivin preoperative intravenous omega-3 PUFAs (Omegaven 10%) infusion (the PUFAs group) or the same volume of 0.9% saline solution infusion (the control group). Infusion was given a day before surgery and repeated four hours before starting extracorporeal circulation (CPB) via the pe ripheral vein at single doses of 100 mL (25 mL/h). Platelet function analysis was performed using multiple electrode aggregometry (MEA, multiplate-analyzer) before starting CPB and 2 h postoperatively for the patients of both groups. Results. There were no clinically relevant differ ences in baseline characteristics between the groups. He matological parameters were not significantly different between the groups pre-, intra- and postoperatively. Dur ing the first 24 h after surgery, the loss of blood was simi lar in the PUFAs and the control group (680 +/- 274 mL and 608 +/- 210 mL, respectively; p = 0.356). Postopera tively, platelet aggregation was not significantly different between the PUFAs and the control group in adenosine diphosphate (ADP) test (39 +/- 11 and 42 +/- 15, respec tively; p = 0.701), arachidonic acid (ASPI) test (64 +/- 24 and 70 +/- 27, respectively; p = 0.525) and trombin receptor-activating peptide (TRAP) test (68 +/- 25 and 75 + 26, respectively; p = 0.396), while their aggregation in collagen (COL) test was statistically significantly lower in the PUFAs related to the control group (32 +/- 15 and 47 +/- 20, re spectively; p = 0.009). Conclusion. Acute pretreatment with omega-3 PUFAs insignificantly affected the activity of platelets and did not influence postoperative blood loss.

Ambulatory phlebectomy under tumescent local anesthesia in a kidney-transplant patient.

INTRODUCTION: Tumescent local anesthesia (TLA) is widely used for ambulatory surgery. Patients with transplanted or gans are on immunosuppressive therapy and with risk for organ rejection or severe infection. CASE REPORT: Saphe nectomy with phlebectomy on the left leg under TLA was performed in a patient with kidney transplantation per formed four years ago. A combination of 35 mg of 1% prilocaine-hydrochloride, 5 mL of 8.4% sodium bicarbonate and 500 microg of epinephrine in 460 mL of normal saline was used for TLA. Overall 750 mL of the solution was used. The patient had satisfactory postoperative analgesia and was discharged home on the same day. Blood levels of urea, cre atinine, estimated glomerular filtration rate (eGFR) and ta crolimus concentration, measured preoperatively and on the second postoperative day, were in a regular range. Prilocaine blood concentrations determined on the 4th, 10th and 16th postoperative hours, were below toxic levels. CONCLUSION: TLA in a kidney-transplanted patient performed for saphe nectomy with phlebectomy proved to be a safe and reliable anesthesia method.

[Surgical treatment of varicose vein using the tumescent technique of local anesthesia].

BACKGROUND/AIM: Tumescent local anesthesia (TLA) is a technique for local and regional anesthesia of the skin and the subcutaneous tissue, using infiltration of large amounts of a diluted solution of local anesthetic. This technique is applied in plastic surgery, liposuction as well as in dermatology for the entire series of dermatocosmetic procedures. The purpose of this study was to determine efficiency of surgical treatment of varicose vein using TLA as an alternative method to a conventional treatment for varicose vein. METHODS: Seventy-two patients with varicose vein were enrolled in the study. All of them were operated on applying TLA, from April 2008 to November 2009. TLA solution consisted of local anesthetics was used. TLA solutions used were: 1% prilocaine-chloride with adrenaline supplement, and 2% lidocaine-chloride and adrenaline in concentration of 0.1%-0.4%. RESULTS: Out of 72 patients, we stripped great saphenous vein from 60 patient and did varicectomy as well as ligation of insufficiently perforating veins. In 12 patients we did partial varicectomy and ligation of perforating veins. There were not any patients with the need for continued surgery, as well as bringing patient to the general anesthesia due to pain during the surgery. One patient came for postoperative opening wound in the groin, one for infection of the wound and one for the formation of seroma in the groin. There were not any allergic reactions or systemic complications in the operations as well as postoperative period. Postoperatively, all the patients were treated with compressive elastic bandage during the period of 6 weeks as well as anticoagulation prophylaxis in the duration of 5 days. CONCLUSION: Surgery of varicose veins with implementation of TLA is easy and safe method with very low percentage of complications and unwanted effects. It is a good alternative method to classic surgery of varicose veins. The economic aspect is a very important component because the cost of this method is significantly lower than that of a classical surgical treatment of varicose veins.

Clinical manifestations, therapy and outcome of pandemic influenza A (H1N1) 2009 in hospitalized patients.

BACKGROUND/AIM: Increasing number of epidemiological and clinical studies to date showed that the pandemic influenza A (H1N1) 2009, by its characteristics, significantly differs from infection caused by seasonal influenza. Therefore, the information about clinical spectrum of manifestations, risk factors for severe form of the disease, treatment and outcome in patients with novel flu are still collected. METHODS; A total of 98 patients (mean age 32 +/- 15 years, range 14-88 years) with the signs and symptoms of novel influenza were treated in the Clinic for Infectious and Tropical Diseases, Military Medical Academy. There were 74 (75.5%) patients with suspected influenza A (H1N1) 2009, 10 (10.2%) with the likelihood and 14 (14.3%) with the confirmed influenza. In all the patients we registered the basic demographic data, risk factors for severe disease, symptoms and signs of influenza, laboratory tests and chest radiography. We analyzed antiviral therapy use and disease outcome (survived, died). RESULTS: The average time from the beginning of influenza A (H1N1) to the admission in hospital was 3 days (0-16 days) and from the moment of hospitalization to the Intensive Care Unit (ICU) admission was 2 days (0-5 days). There were 49 (50.0) patients, 20-29 years of age and 5 (5.1) patients older than 65. A total of 21 (21.4%) patients were with underlying disease, 18 (18.4%) were obese, 19 (19.4) were cigarette smokers. All of the patients had fever, 81 (82.6%) cough, while dyspnea and diarrhea were registered in 4 of the patients. In more than 75% of the patients laboratory tests were within normal limits. The real-time polymerase chain reaction (PCR) test for identification of influenza A (H1N1) 2009 was positive in 14 (77.8%), while pneumonia was verified in 30 (30.7%) of the patients. Six (6.1%) patients, mean age of 45 +/- 14 years (31-59 years) were admitted to the ICU, of whom five (5.1%) had Adult Respiratory Distress Syndrome (ARDS). Risk factors were registered more frequently in the patients with acute respiratory failure (14.2% vs 4.9%, p < 0.05). A total of 67 (68.4%) patients received oseltamivir, 89 (90.1%) was applied to antibiotics and 64 (65.3%) were treated with a combined therapy. Antiviral therapy was applied to 43 (43.3%) patients in the first 48 hours from the onset of the disease, of whom only one (3.4) developed ARDS. Fatal outcome was noted in 2.0% of the patients (2 of 98 patients) and in 33.3% of the patients treated in the ICU. CONCLUSION: Novel influenza A (H1N1) is most commonly manifested as a mild acute respiratory disease, which usually affects young healthy adults. A small number of the patients develop severe illness with acute respiratory failure and death. Patients seem to have benefit from antiviral therapy especially in first 48 hours.

BACKGROUND/AIM: Pandemic of A H1N1 influenza is noted for its rapid spreading and life-threatening consequences like acute respiratory distress syndrome (ARDS) which requires mechanical ventilation (MV) and intensive therapy (IT).The aim of the study was to determine the significance of mechanical ventilation application in the presence of comorbidities on the outcome of the disease and patients with severe forms of acute influenza caused by A H1N1 virus. METHODS: Five patients with acute respiratory failure caused by A H1N1 influenza that required MV were included in the study. Course and outcome of the treatment were monitored in relation to age and sex of the patients, concomitant diseases, time of influenza beginning, a time of admittance in an intensive care unit, a time of an endotracheal intubation and MV beginning, MV duration and occurrence of secondary infections. RESULTS: Three patients were on a very prolonged MV (39, 43 and 20 days, respectively) and they all survived. Two patients with a significantly shorter duration of MV (14 and 12 days, respectively) died because of a very severe clinical course and concomitant diseases. Unexpectedly, we found a positive correlation between duration of MV and survival although two patients, who were on MV for the longest period of time (43 and 39 days, respectively), developed, as a complication, secondary bacterial pneumonia. CONCLUSION: Intensive therapy of patients with ARDS due to A H1N1 influenza virus requires MV which should be carried out according to guidelines of international expert forums. That is in accordance with our unexpected observation on negative correlation between duration of MV and fatal outcome. Intensive treatment of these patients, specially MV, can be very prolonged and, therefore, requires specialized teams of anesthesiologists, separate, isolated intensive therapy units and high level of medical staff protection, as was the case in this study, so no member of medical staff was infected.

Clinical parameters of the local anesthetic effects of bupivacaine applied with and without a vasoconstrictor in oral implantology.

BACKGROUND/AIM: Bupivacaine (Marcaine), homologue of mepivacaine, chemically related to lidocaine, is used as a local anesthetic for local infiltration, peripheral nerve block, retrobulbar block, symphathetic block, and caudal and epidural anesthesia. The aim of this investigation was to determine and to compare clinical parameters of the local anesthetic effects of bupivacaine applied with and without a vasoconstrictor. METHODS: This investigation included a total of 30 randomly selected patients, who ranged in age from 30-60 years, with partial or total anodontia in the molar region of the mandible. These patients with total or partial edentulous molar part of the mandible, scheduled for dental implantation placement, were asked to participate in the study. In the first phase of the investigation, the patients were subjected to local anesthesia with 3.5 cm3 of 0.5% bupivacaine with a vasoconstrictor (adrenalin, 1: 200,000) in the right side of the mandible. After administering local anesthesia, the placement of blade, cylindrical, transdental (B.C.T.) implants was performed. In the second stage of the investigation, in 7-10 days period after the first oral surgery, the patients were subjected to local anesthesia with 3.5 cm3 of 0.5% bupivacaine, but without a vasoconstrictor, in the left side of the mandible. After administering local anesthesia, the placement of B.C.T. implants was performed. During the performance of both oral surgery procedures, the following clinical parameters of the local anesthetic effects were monitored: latent period, duration and the potency of anesthesia, and the evaluation of the postoperative pain level. RESULTS: The latent period under local anesthesia with 3.5 cm3 of 0.5% bupivacaine and vasoconstrictor was statistically significantly shorter than without vasoconstrictor. The duration of local anesthesia was longer without vasoconstrictor. There was no difference in the potency of anesthesia with or without a vasoconstrictor, while the lowest level of postoperative pain was found after administering bupivacaine without a vasoconstrictor use. CONCLUSION: The results of this investigation show that bupivacaine without a vasoconstrictor is efficient when used for local anesthesia in placing dental implants since it provides better blood circulation required for good dental implant osseointegration.

[Papillary muscle rupture due to acute myocardial infarction followed by cardiogenic shock, pulmonary edema, and acute renal failure].

AIM: The case of successfull surgical treatment of anterolateral papillary muscle rupture due to acute myocardial infarction with cardiogenic shock, pulmonary edema and acute renal failure. CASE REPORT: A 62-year old male from Belgrade with chest pain, hypotension and a new heart murmur refused hospitalization at the Military Medical Academy. On the third day of his illness he was readmitted to MMA as an emergency due to hemoptysis. Examination revealed mitral valve anterolateral papillary muscle rupture. The patient, with signs of cardiogenic shock and acute renal failure, was immediately operated on. The surgery was performed using extracorporeal circulation. An artificial mitral valve was implanted, and myocardial revascularization accomplished with one venous graft of the left anterior descending artery. On the second postoperative day, hemodialysis was carried out due to acute renal failure. On the 28th postoperative day, the patient was discharged from the hospital being hemodynamically stable with normal renal function and balanced anticoagulation. The case is interesting in terms of unrecognized papillary muscle rupture that led to the development of cardiogenic shock, hemoptysis and acute renal failure. CONCLUSION: Papillary muscle rupture is a fatal complication of acute myocardial infarction. Early recognition and urgent surgical intervention were life-saving in the case of complete papillary muscle rupture. Surgical treatment, regardless of high risk, is the procedure of choice.
