Background: The fact that pulmonary complications occur in 20–60% of the patients subjected to abdominal operations clearly indicates that the lungs are the most endangered organ during the postoperative period. Objective: The aim of this study was to demonstrate the impact of cholecystectomy on postoperative respiratory disturbances by comparing the laparotomic cholecystectomy with laparoscopic gallbladder removal. Patients and Methods: A hundred cholecystectomized patients were included in the prospective randomized clinical trial. Half of the patients were operated on by the laparotomic procedure, whereas the other half underwent laparoscopic cholecystectomy. Spirometric parameters, arterial blood gases, and acid-base balance were determined before the operation, and at 6, 24, 72 and 144 h postoperatively. Abdominal distension was assessed by auscultating intestinal peristaltics, abdominal circumference measurement, and time interval to restitution of defecation. Results: Six hours postoperatively, the values of ventilation parameters decreased on average by 40–50% from the baseline preoperative values in both groups of patients. The group of patients submitted to laparotomic cholecystectomy had significantly lower spirometric values and slower recovery of the ventilation parameters than the laparoscopic cholecystectomy group. Abdominal circumference was significantly greater and the time needed for restitution of peristaltics and defecation was significantly longer in the laparotomic cholecystectomy group compared to the group of laparoscopic cholecystectomy. Conclusions: Statistically significant impairments including hypoxia, hypocapnia and hyperventilation were observed in the patients submitted to laparotomic cholecystectomy, indicating the presence of objective respiratory risk, especially in elderly patients and patients with obstructive pulmonary diseases or cardiac insufficiency.

Antiepileptic/teratogen valproate (VPA) is a histone deacetylase inhibitor/ epigenetic drug proposed for the antitumor therapy where it is generally crucial to target poorly or undifferentiated cells to prevent a recurrence. Transplanted rodent gastrulating embryos-proper (primitive streak and three germ layers) are the source of teratoma/teratocarcinoma tumors. Human primitive-streak remnants develop sacrococcygeal teratomas that may recur even when benign (well differentiated). To screen for unknown VPA impact on teratoma-type tumors, we used original 2-week embryoderived teratoma in vitro biological system completed by a spent media metabolome analysis. Gastrulating 9.5-day-old rat embryos-proper were cultivated in Eagle's minimal essential medium (MEM) with 50% rat serum (controls) or with the addition of 2 mM VPA. Spent media metabolomes were analyzed by FTIR. Compared to controls, VPA acetylated histones; significantly diminished overall teratoma growth, impaired survival, increased the apoptotic index, and decreased proliferation index and incidence of differentiated tissues (e.g., neural tissue). Control teratomas continued to grow and differentiate for 14 days in isotransplants in vivo, but in vitro VPA-treated teratomas resorbed. Principal component analysis of FTIR results showed that spent media metabolomes formed well-separated clusters reflecting the treatment and day of cultivation. In metabolomes of VPA-treated teratomas, we found elevation of previously described histone acetylation biomarkers [amide I a-helix and A(CH 3)/A(CH 2)]) with apoptotic biomarkers within the amide I region for b-sheets, and unordered and CH 2 vibrations of lipids. VPA may be proposed for therapy of the undifferentiated component of teratoma tumors and this biological system Abbreviations ASD, autism spectrum disorder; EC, embryonal carcinoma; GTS, growing teratoma syndrome; HDACi, histone deacetylase inhibitor; MEM, minimal essential medium; PCA, principal component analysis; PCNA, proliferating cell nuclear antigen; RMSEC, root mean square error of calibration; RMSECV, root mean square error of cross-validation; SAHA, suberoylanilidehydroxamic acid; VPA, valproate; WEC, whole rat embryo.

Results: in all the patients a successful outcome has been observed with a complete resolution of pain symptom. extravertebral vascular cement leakage has been observed in 3 patients, without any clinical radicular syndrome onset due to the epidural diffusion. clinical and radiological follow-up showed stability of the treatment and absence of pain in all patients.Conclusion: percutaneous treatment with vertebroplasty for symptomatic vertebral hemangiomas is a valuable, less-invasive, and a quick method that allows a complete and enduring resolution of the painful vertebral symptoms without findings of the vertebral body's fracture.

Snake venom poisoning is a medical emergency that requires urgent therapeutic procedures. The treatment of venomous snakebites is still controversial because of unclear therapeutic modalities. Choice of treatment is dictated in part by regional characteristics with regard to patient population and types of venomous snakes. The purpose of the study presented here was to report regional experience with venomous snakebites and to describe first-aid, pre-hospital, and hospital therapeutic procedures for horned viper bite. During a 16-year period, from 1980 to 1996, at the Clinical Hospital Split (Croatia) we collected data on 389 victims of horned viper bite. Incidence of the local and general complications is presented. We also reviewed therapeutic modalities and outcome with special attention to compartment syndromes and the indications for fasciotomy.

AimTo compare the overall and disease-specific mortality of Croatian male athletes who won one or more Olympic medals representing Yugoslavia from 1948 to 1988 or Croatia from 1992 to 2016, and the general Croatian male population standardized by age and time period.MethodsAll 233 Croatian male Olympic medalists were included in the study. Information on life duration and cause of death for the Olympic medalists who died before January 1, 2017, was acquired from their families and acquaintances. We asked the families and acquaintances to present medical documentation for the deceased. Data about the overall and disease-specific mortality of the Croatian male population standardized by age and time period were obtained from the Croatian Bureau of Statistics (CBS). Overall and disease-specific standard mortality ratios (SMR) with 95% confidence intervals (CI) were calculated to compare the mortality rates of athletes and general population.ResultsAmong 233 Olympic medalists, 57 died before the study endpoint. The main causes of death were cardiovascular diseases (33.3%), neoplasms (26.3%), and external causes (17.6%). The overall mortality of the Olympic medalists was significantly lower than that of general population (SMR 0.73, 95% CI 0.56-0.94, P = 0.013). Regarding specific causes of death, athletes’ mortality from cardiovascular diseases was significantly reduced (SMR 0.61, 95% CI 0.38-0.93, P = 0.021).ConclusionsCroatian male Olympic medalists benefit from lower overall and cardiovascular mortality rates in comparison to the general Croatian male population.
