Abstract
INTRODUCTION The robotic transabdominal preperitoneal approach (rTAPP) is a relatively recent technique for the treatment of inguinal hernia. To achieve optimal results, the 10 golden rules described must be followed. Surgeons in training often review videos to familiarize themselves with new techniques, YouTube being one of the most used platforms. The objective of this study is to carry out an evaluation of the 10 most viewed videos on YouTube of inguinal hernia repair by transabdominal preperitoneal approach (rTAPP) to determine if the 10 golden rules are met. METHODS Identify and evaluate the 10 videos with the highest number of views related to rTAPP. Three experienced Surgeons evaluated compliance with the 10 golden rules using a Likert scale. Data were analyzed in Excel (Microsoft) and plotted with Tableau (Tableau Inc). The consistency between evaluators was determined using Cronbach's alpha, considering a value >0.7 acceptable. RESULTS The average overall evaluation was 3.63 with a range of 2.6 to 4.9. The scores related to compliance with the rules 1, 2, 9, 10 were satisfactory; on the other hand, rules 3, 4, 5, 7 and 8 were weak, particularly rule number 7. Internal consistency was observed between raters with a Cronbach's alpha of 0.98. CONCLUSIONS The lack of compliance with the 10 golden rules in most of the videos demonstrates that the use of videos (YouTube) is not an adequate resource for learning robot-assisted inguinal hernia cure.

Abstract
This study assessed the effect of donor´s age and two different extenders in the sperm quality of chilled semen in Majorera bucks. In experiment 1, semen was individually processed from 5 young (10–12 months old) and 4 mature (3–5 years old) bucks and then was diluted in two different extenders: EY (Tris‐glucose, 12% egg yolk) and CEY (Tris‐glucose, 12% clarified egg yolk) and cooled at 4°C; semen quality (sperm motility, percentages of alive spermatozoa, acrosome status and abnormal spermatozoa) was evaluated at 24, 48, 72 and 96 hr after cooling. In experiment II, 72 Majorera goats were assigned to four experimental groups: for groups 24‐EY (n = 18) and 24‐CEY (n = 18), goats were inseminated with EY and CEY cooled semen for 24 hr, respectively, while for groups 72‐EY (n = 18) and 72‐CEY (n = 18), goats were inseminated with EY and CEY cooled semen for 72 hr, respectively. In vitro results confirmed that only ejaculate volume and sperm concentration were significantly different between young and mature bucks. In addition, semen quality was similar between both diluents, presenting values for the first 48 hr similar to that recorded in fresh samples. The fertility rate was around 70% after 24 hr (4°C) in both groups, but the kidding rate was significantly lower (44.4%, p < .05) in goats inseminated with EY diluent preserved for 72 hr. Our results showed that the semen samples may be stored at 4°C in media with egg yolk or clarified egg yolk, and, therefore, the use of clarified egg yolk may represent a valid alternative to chill semen samples. Finally, young bucks (older than 10–12 months) of Majorera breed could be successfully used in breeding programmes with similar efficacy to older males.

Abstract
BACKGROUND Colombia's National Army is one of the largest military institutions in the country based on the number of serving members and its presence throughout the country. There have been reports of cases of acute or chronic cases of Chagas disease among active military personnel. These may be the result of military-associated activities performed in jungles and other endemic areas or the consequence of exposure to Trypanosoma cruzi inside military establishments/facilities located in endemic areas. The aim of the present study was to describe the circulation of T. cruzi inside facilities housing four training and re-training battalions [Battalions of Instruction, Training en Re-training (BITERs)] located in municipalities with historical reports of triatomine bugs and Chagas disease cases. An entomological and faunal survey of domestic and sylvatic environments was conducted inside each of these military facilities. METHODS Infection in working and stray dogs present in each BITER location was determined using serological and molecular tools, and T. cruzi in mammal and triatomine bug samples was determined by PCR assay. The PCR products of the vertebrate 12S rRNA gene were also obtained and subjected to Sanger sequencing to identify blood-feeding sources. Finally, we performed a geospatial analysis to evaluate the coexistence of infected triatomines and mammals with the military personal inside of each BITER installation. RESULTS In total, 86 specimens were collected: 82 Rhodnius pallescens, two Rhodnius prolixus, one Triatoma dimidiata and one Triatoma maculata. The overall T. cruzi infection rate for R. pallescens and R. prolixus was 56.1 and 100% respectively, while T. dimidiata and T. maculata were not infected. Eight feeding sources were found for the infected triatomines, with opossum and humans being the most frequent sources of feeding (85.7%). Infection was most common in the common opossum Didelphis marsupialis, with infection levels of 77.7%. Sylvatic TcI was the most frequent genotype, found in 80% of triatomines and 75% of D. marsupialis. Of the samples collected from dogs (n = 52), five (9.6%; 95% confidence interval: 3.20-21.03) were seropositive based on two independent tests. Four of these dogs were creole and one was a working dog. The spatial analysis revealed a sympatry between infected vectors and mammals with the military population. CONCLUSIONS We have shown a potential risk of spillover of sylvatic T. cruzi transmission to humans by oral and vectorial transmission in two BITER installations in Colombia. The results indicate that installations where 100,000 active military personnel carry out training activities should be prioritized for epidemiological surveillance of Chagas disease.

Abstract
BACKGROUND Leishmaniasis is one of the most important infectious diseases affecting the Colombian National Army due to the high number of reported cases and exposure throughout military operations in endemic areas. The main aim of this study was to estimate the geographical distribution along with the genetic diversity and treatment outcome of Leishmania species in Colombian military personnel. METHODS Skin lesion samples by smear and aspirate were collected in 136 patients having parasitological cutaneous leishmaniasis (CL) diagnosis. DNA was extracted, the nuclear marker heat shock protein 70 (HSP70) was amplified by PCR and sequenced. Leishmania species were identified by BLASTn. The geo-spatial distribution of the identified parasites was determined according to the possible site of infection. Gene tree was constructed by maximum likelihood (ML), diversity indices (π, h) were estimated and haplotype network was constructed under the Templeton-Crandall-Sing algorithm in order to determine the geographic relationships of the genetic variants of Leishmania species circulating in Colombian military population. RESULTS The species were identified in 77.94% of the samples, with a predominance of L. braziliensis (65.09%), followed by L. panamensis (31.13%), L. naiffi by the first time reported in Colombia in two patients (1.89%) as well as L. lindenbergi in a single patient (0.945%) with possible infection in the municipality of Miraflores, Guaviare and L. infantum in a single patient (0.945%) notified with CL in the municipality of Tumaco, Nariño. The phylogenetic analysis was consistent according to bootstrap, showing four strongly differentiated clades. CONCLUSIONS The geo-spatial distribution suggested that L. braziliensis has a greater abundance, while L. panamensis has a greater dispersion. The phylogenetic relationships of Leishmania species in Colombian military personnel was estimated with the confirmation of two new species circulating without prior report in the country and a species with no background for CL in the Colombian army. A substantial genetic diversity of Leishmania braziliensis was defined. This study contributes through the understanding of the molecular epidemiology to the CL transmission in Colombia.

Abstract
Background The National Army of Colombia is present in all of the national territory, focused in sylvatic zones where they are exposed continually to potential risk of transmission of Trypanosoma cruzi, the etiological agent of the Chagas disease. People of this study were active personal that were born and lived during their first years in endemic areas of transmission through domiciled vectors as Rhodnius prolixus. Aim The main aim of this study was to estimate the prevalence of Chagas disease in the active military population of the National Army, gathered in five departments. Methods An observational and descriptive study with cross-sectional analysis was carried out. Blood sample each patient in order to apply serological diagnosis by two different Enzyme Linked ImmunoSorbent Assay tests, following the algorithm of National Institute of Health, Colombia. In cases of serum results with inconsistencies, a Hemagglutination Inhibition test and Indirect Immunofluorescence assay test were performed to solve inconclusiveness. Positive samples by two different tests were considered seropositive. Additionally, to each positive sample by at least one serological test, we did extraction of DNA for molecular diagnosis. Results 295 serums were analyzed and two of them were positive in order to get a prevalence of 0.68%. Two samples analyzed by molecular diagnosis were negative. Conclusion The prevalence was < 1% It is probable the infection in the seropositive individuals occurred before enlisting in the military service due to origin locations with transmission such as Casanare and Boyacá. These findings allow defining the prevention and control programs of chronic cases and reduction in the disease burden.

Abstract
Background BRCA1 and BRCA2 (BRCA1/2)-deficient tumors display impaired homologous recombination repair (HRR) and enhanced sensitivity to DNA damaging agents or to poly(ADP-ribose) polymerase (PARP) inhibitors (PARPi). Their efficacy in germline BRCA1/2 (gBRCA1/2)-mutated metastatic breast cancers has been recently confirmed in clinical trials. Numerous mechanisms of PARPi resistance have been described, whose clinical relevance in gBRCA-mutated breast cancer is unknown. This highlights the need to identify functional biomarkers to better predict PARPi sensitivity. Patients and methods We investigated the in vivo mechanisms of PARPi resistance in gBRCA1 patient-derived tumor xenografts (PDXs) exhibiting differential response to PARPi. Analysis included exome sequencing and immunostaining of DNA damage response proteins to functionally evaluate HRR. Findings were validated in a retrospective sample set from gBRCA1/2-cancer patients treated with PARPi. Results RAD51 nuclear foci, a surrogate marker of HRR functionality, were the only common feature in PDX and patient samples with primary or acquired PARPi resistance. Consistently, low RAD51 was associated with objective response to PARPi. Evaluation of the RAD51 biomarker in untreated tumors was feasible due to endogenous DNA damage. In PARPi-resistant gBRCA1 PDXs, genetic analysis found no in-frame secondary mutations, but BRCA1 hypomorphic proteins in 60% of the models, TP53BP1-loss in 20% and RAD51-amplification in one sample, none mutually exclusive. Conversely, one of three PARPi-resistant gBRCA2 tumors displayed BRCA2 restoration by exome sequencing. In PDXs, PARPi resistance could be reverted upon combination of a PARPi with an ataxia-telangiectasia mutated (ATM) inhibitor. Conclusion Detection of RAD51 foci in gBRCA tumors correlates with PARPi resistance regardless of the underlying mechanism restoring HRR function. This is a promising biomarker to be used in the clinic to better select patients for PARPi therapy. Our study also supports the clinical development of PARPi combinations such as those with ATM inhibitors.

Abstract
INTRODUCTION Laparoscopic cholecystectomy is a common procedure in general surgery, and in complex cases it is important for the surgeon to know all the alternatives with low associated morbidity. Laparoscopic subtotal cholecystectomy should be considered as an option when a critical view of safety cannot be obtained, because it has a low complication rate and gives the advantages of minimally invasive surgery. METHODS Retrospective study of laparoscopic subtotal cholecystectomies in an eight years period. RESULTS A total of 1,059 laparoscopic cholecystectomies were performed; 22 were subtotal cholecystectomies, without conversion. Biliary fistula (9%) and intraabdominal collections (4.5%) were the most common complications described. No iatrogenic bile duct injuries or deaths were reported. Our follow-up period was 32months, no recurrences were reported. CONCLUSIONS Laparoscopic subtotal cholecystectomy is a safe and effective procedure. It should be considered as an option in complex cases.

Abstract
UNLABELLED Adjuvant intravesical bacillus Calmette- Guérin (BCG) therapy is the standard conservative adjuvant treatment and the most effective regimen for patients with high-risk non-muscle-invasive bladder cancer (NMIBC). The term "BCG failure" is generally used to refer to recurrence or progression following BCG therapy, as experienced by many patients. However, the term has been defined inconsistently, and several studies have indicated that patients with a particular pattern of BCG failure have a worse prognosis. There are many different treatment options for patients who experience BCG failure. OBJECTIVE To summarize the different current definitions of BCG failure and the present treatment options available for patients with high-risk NMIBC who experience BCG failure. EVIDENCE SYNTHESIS Overall, the failure rate in response to BCG is about 40-50%. Most guidelines recommend that patients failing BCG should be offered radical cystectomy (RC). The significant potential for progression specific to high-risk NMIBC leads some clinicians to argue that immediate RC should be considered the preferred first-line treatment in high-risk patients, bearing in mind that it achieves a long-term survival rate in excess of 90% with ongoing improvements in morbidity. While other salvage intravesical treatments have to be considered oncologically inferior to RC, several therapies are now available if the patient is unfit to undergo RC or if bladder preservation is the objective, and some agents have shown promise in the context of BCG failure. CONCLUSIONS The definition, prediction, and treatment of BCG failure remain topics of debate. Patients with BCG failure need carefully selected, individualized therapy in experienced hands. Stratification of patients with BCG failure into groups can identify those with a better or worse prognosis. RC should be the selected option if a patient experiences BCG failure, but several promising intravesical salvage options are available for those cases in which the patient is unfit for surgery or bladder preservation is preferred. Currently data are still inadequate to allow formulation of definitive recommendations, and larger and higher quality studies of salvage intravesical therapies are urgently required.

Abstract
The objective of this study is to determine the ability of the GEARS scale (Global Evaluative Assessment of Robotic Skills) to differentiate individuals with different levels of experience in robotic surgery, as a fundamental validation. This is a cross-sectional study that included three groups of individuals with different levels of experience in robotic surgery (expert, intermediate, novice) their performance were assessed by GEARS applied by two reviewers. The difference between groups was determined by Mann-Whitney test and the consistency between the reviewers was studied by Kendall W coefficient. The agreement between the reviewers of the scale GEARS was 0.96. The score was 29.8 ± 0.4 to experts, 24 ± 2.8 to intermediates and 16 ± 3 to novices, with a statistically significant difference between all of them (p < 0.05). All parameters from the scale allow discriminating between different levels of experience, with exception of the depth perception item. We conclude that the scale GEARS was able to differentiate between individuals with different levels of experience in robotic surgery and, therefore, is a validated and useful tool to evaluate surgeons in training.

Abstract
Background and Objective: Technical skills assessment is considered an important part of surgical training. Subjective assessment is not appropriate for training feedback, and there is now increased demand for objective assessment of surgical performance. Economy of movement has been proposed as an excellent alternative for this purpose. The investigators describe a readily available method to evaluate surgical skills through motion analysis using accelerometers in Apple's iPod Touch device. Methods: Two groups of individuals with different minimally invasive surgery skill levels (experts and novices) were evaluated. Each group was asked to perform a given task with an iPod Touch placed on the dominant-hand wrist. The Accelerometer Data Pro application makes it possible to obtain movement-related data detected by the accelerometers. Average acceleration and maximum acceleration for each axis (x, y, and z) were determined and compared. Results: The analysis of average acceleration and maximum acceleration showed statistically significant differences between groups on both the y (P = .04, P = .03) and z (P = .04, P = .04) axes. This demonstrates the ability to distinguish between experts and novices. The analysis of the x axis showed no significant differences between groups, which could be explained by the fact that the task involves few movements on this axis. Conclusion: Accelerometer-based motion analysis is a useful tool to evaluate laparoscopic skill development of surgeons and should be used in training programs. Validation of this device in an in vivo setting is a research goal of the investigators' team.

Abstract
OBJECTIVES Explore a new target for molecular diagnosis of Leishmania. MATERIALS AND METHODS We evaluated the utility of the gene that encodes the heat shock protein 20-kDa (Hsp20) for detecting Leishmania by polymerase chain reaction (PCR). PCR was normalized and analytical parameters were determined, as well as the validity and diagnostic accuracy, and concordance with the PCR - 18S. PCR-Hsp20 with DNA was obtained from a group of clinical samples from different sources. RESULTS The analytical parameters were adequate. The sensitivity obtained was 86% and the specificity was 100%. The concordance with the reference method was good (κ = 0.731), which supports its potential use for diagnosis. The possibility of subsequent identification of the species by sequencing the amplified product gives an additional advantage. CONCLUSIONS The usefulness of this gene as a new target for the detection of Leishmania was demonstrated. Because of its potential, it is recommended to improve the sensitivity of the method and to evaluate it in different endemic regions.

Abstract
OBJECTIVE To define the natural history of T1G3 bladder tumor not receiving intravesical Bacillus Calmette-Guerin (BCG) and assess the diagnostic and therapeutic value of a second transurethral resection (Re-TUR) in these patients. PATIENTS AND METHODS Retrospective study on the natural history of 210 patients treated at two institutions for T1G3 bladder carcinoma without associated CIS. In no case was BCG administered; 79 (37.6%) received TUR alone, and 131 (62.4%) Re-TUR 4 to 6 weeks later; 23 (12.4%) underwent cystectomy for tumor progression. RESULTS Median follow-up was 55 (78 IQR) months, male/female ratio 8/1, and mean age 70.6+11.8 (range 37-93). 19.5% were free of recurrence at 10 years, and 61.9% free of progression. Independent prognostic factors for progression were solid pattern (HR: 2.71; P=.0004), multiplicity (HR: 2.26; P=.003), and recurrence at 3 months (HR: 3.4; P=.003). Cancer-specific survival was 81.5% at 5 and 69% at 10 years. Independent predictors of survival were: progression during the first year (HR: 17.9; P<.0001), solid pattern (HR: 2.13; P=.02), multiplicity (HR: 2.05; P=.03), and age>65 years (HR: 2.9; P=.03). Re-TUR avoided under-staging (7.4%), detected T1G3 residual disease (10.7%), reduced recurrence rate at 3 months (11.4 to 4.6%; P=.06), and rate of progression on the 1st year (13.9 to 3.8%; P=.0075). However, in these patients the risk remains and no differences were detected in the long term in terms of recurrence (log-rank, P=.14), progression (P=.91), or cancer death (P=.21) in patients treated with Re-TUR. CONCLUSION The recurrence in the first 3 months of a T1G3 tumor not receiving BCG is the main risk factor for progression, and progression of this type of tumors within the first year is the main factor of cancer death. The Re-TUR improves both variables but it does not change the long-term prognosis.

Abstract
UNLABELLED The char produced in the thermolysis of granulated scrap tyres has few market outlets, reducing the economic viability of the thermolytic process. This paper reports the potential of this char as a low-cost precursor of porous carbons. The tyre-derived char was demineralized in either alkaline or acidic media to reduce its ash, zinc, sulfur, and silica contents. The lowest impurity content was achieved with an HNO3/H2O treatment. The resulting demineralized char was then subjected to activation by KOH or CO2. The Brunauer-Emmett-Teller (BET)-specific surface area of the activated carbon produced by the KOH treatment was 242 m2/g, whereas that of the CO2-activated carbon was 720 m2/g. The textural properties of the latter product were similar to those of some commercial activated carbons. The use of tyre-derived char as a precursor of porous carbons could render the thermolytic treatment of scrap tyres more economically attractive. IMPLICATIONS Char produced in thermolysis of granulated scrap tyres has a few market outlets; in this paper an alternative for its use is presented. The char was converted into activated carbon with textural properties similar to those of some commercial activated carbons. This process could render the thermolytic treatment of scrap tyres more economically attractive.

Abstract
BACKGROUND Training models in laparoscopic surgery allow the surgical team to practice procedures in a safe environment. We have proposed the use of a 4-task, low-cost inert model to practice critical steps of laparoscopic common bile duct exploration. METHODS The performance of 3 groups with different levels of expertise in laparoscopic surgery, novices (A), intermediates (B), and experts (C), was evaluated using a low-cost inert model in the following tasks: (1) intraoperative cholangiography catheter insertion, (2) transcystic exploration, (3) T-tube placement, and (4) choledochoscope management. Kruskal-Wallis and Mann-Whitney tests were used to identify differences among the groups. RESULTS A total of 14 individuals were evaluated: 5 novices (A), 5 intermediates (B), and 4 experts (C). The results involving intraoperative cholangiography catheter insertion were similar among the 3 groups. As for the other tasks, the expert had better results than the other 2, in which no significant differences occurred. The proposed model is able to discriminate among individuals with different levels of expertise, indicating that the abilities that the model evaluates are relevant in the surgeon's performance in CBD exploration. CONCLUSIONS Construct validity for tasks 2 and 3 was demonstrated. However, task 1 was no capable of distinguishing between groups, and task 4 was not statistically validated.

Abstract
A simple, low-cost model is described that allows for accurate reproduction of the main steps in performing laparoscopic common bile duct exploration. Background: Training and experience of the surgical team are fundamental for the safety and success of complex surgical procedures, such as laparoscopic common bile duct exploration. Methods: We describe an inert, simple, very low-cost, and readily available training model. Created using a “black box” and basic medical and surgical material, it allows training in the fundamental steps necessary for laparoscopic biliary tract surgery, namely, (1) intraoperative cholangiography, (2) transcystic exploration, and (3) laparoscopic choledochotomy, and t-tube insertion. Results: The proposed model has allowed for the development of the skills necessary for partaking in said procedures, contributing to its development and diminishing surgery time as the trainee advances down the learning curve. Further studies are directed towards objectively determining the impact of the model on skill acquisition. Conclusion: The described model is simple and readily available allowing for accurate reproduction of the main steps and maneuvers that take place during laparoscopic common bile duct exploration, with the purpose of reducing failure and complications.

Abstract
All indications of linezolid (LZD) in Intensive Care Units (ICU) were included as cases in an observational, prospective and multicentre study. One hundred thirty-nine indications were analyzed. In most cases (92.7%), treatment for nosocomial infections was indicated. The most frequent infection was pneumonia (42.7%), followed by catheter-related bacteraemias (CRB). A total of 58.7% of the indications were empirical and in 45.7% of the cases the cultures confirmed infection by gram-positive cocci (GPC). In 43 cases (31.2%), the indication was made as a rescue measure (mainly due to clinical failure) in patients previously treated with glycopeptides. Of isolated GPC, 70.2% were methicillin-resistant. The cure rate of the population per intent-to-treat was 73.2%. Only one case of thrombocytopenia was recorded. Conclusions. LZD is used with a high degree of diagnostic safety. In the ICU, it is primarily indicated to treat pneumonias and CRB with good clinical and microbiological response. This antibiotic has acted as a good therapeutic resource against clinical failure in infections treated with glycopeptides.

Gold-standard treatment for this clinical situation remains the resection of the urachus in its entire tract with or without partial resection of the bladder. Our aim is to up-date authors's experience in the minimally invasive surgical treatment of acquired urachal disease. METHODS From 2001 to 2007, 14 patients were operated for acquired urachal disease at our institution. A three portal technique previously described by the authors was employed. The diagnosis of acquired uracal disease was confirmed in all cases and the resection of the urachus in its entire tract performed in cephalocaudal direction onto the bladder. Operative and demographic data was prospectively collected and analysis retrospectively performed. RESULTS Mean operative time was 63 minutes (45,110), minimal blood loss, and no conversions to open surgery or perioperative complications were verified. The majority of the patients were discharged in the first 24 hours. At a follow-up of 22 months no recurrences of urachal pathology recurrences have been verified. CONCLUSIONS Laparoscopy plays a significant role in the management of symptomatic urachus anomalies. It allows objective confirmation of clinical diagnosis and adequate resection of the urachus in a safe and efficient fashion, while providing the well-known advantages of minimally acces surgery. Preoperative evaluation work-up has minimal impact of therapeutical decision.

Abstract
OBJECTIVES Morbidity secondary to intravesical Bacillus Calmette-Guèrin (BCG) may present both locally and systemically. Most patients suffer a self-limited irritative voiding syndrome. Often, there are not unified criteria for the management of BCG side effects. After treating more than 500 patients with BCG we developed a practical guideline for the management of its morbidity. We present clearly and schematically the practice guideline we follow in our Center when the patient presents symptoms and morbidity secondary to BCG intravesical installations. METHODS We analyze and describe, following the literature and our own experience, the management of adverse events experienced by patients treated with intravesical BCG, since the initial implementation of the protocol for its indication in patients with high risk non-muscle invasive bladder tumors and/or CIS. RESULTS Irritative voiding symptoms are among the most frequent symptoms, generally self-limited; but if they persist (> 48 hours) will have the urologist treat them depending on intensity and duration. Macroscopic hematuria is not unfrequent and diminishes with an expectant approach and water intake. But, it may also be a urinary tract infection or residual tumor. A febrile syndrome, if present, is usually self-limited to the first 24-48 hours and below 38.5 degrees C without general status affectation. In cases of persistence and/or sepsis, tuberculostatic treatment and/or corticoids should be started. Other clinical pictures may appear, such as orchyoepididymitis, arthritis, etc. CONCLUSIONS Proper diagnosis and treatment of adverse events after BCG therapy are basic to allow intravesical immunotherapy be properly prescribed and managed by urologists, enabling a proper treatment of patients and avoiding the possibility of more severe complications.

Abstract
Ultrasound in a liquid phase cause mass and heat transfer across the liquid through cavitational processes which act as nanoreactors to generate unstable mechanical equilibrium. The effect of 1 MHz ultrasound on the inactivation of Cryptosporidium parvum was investigated. Continuous irradiation of ultrasound (20 min) increased temperature due to cavitational phenomena. Ultrasound irradiation of liquid containing C. parvum showed significant quantitative changes in pH, temperature and inactivation of C. parvum (102.7 oocysts killed/s) with a minimum energy consumption (0.05 oocysts/s).

Abstract
The metastases of prostate cancer shows the regional lymphatic dissemination, being the cervical lymphatic metastases to infrequent and little reported in Literature. In the present work we contributed a new observation of this organization. We displayed a clinical case with lateral mass cervical left, abdominal pain and diarrheic. When making biopsy of cervical adenopathy reported adenocarcinoma prostate metastases. Colonoscopy with biopsy was made whose results were carcinoma little differentiated infiltrated necrotic center to rectum. The complementary studies demonstrated bilateral aortic adenopathys without injuries in thorax. Within the diagnosis differential of the cervical adenopathys in neck in adult men it must consider the prostate carcinoma, because in an early diagnosis and adapting treatment it can prolong the survive.

Abstract
Cutaneous metastases from a renal cell carcinoma are rarely diagnosed during life. We report a case of renal carcinoma metastatic to the skin that occurred 18 months after kidney removal. The cutaneous metastasis was excised. Cutaneous metastases from urological tumors are uncommon and occur in 1% of the patients, and their clinical appearance may mimic other common dermatological disorders affecting patients with advanced malignancies.

Abstract
AbstractGame bird farming is associated with high parasite levels that reduce farm productivity, reduce survival after releasing, and may pose a health risk for natural populations. The efficacy of albendazole (orally, 20 mg kg− 1) was evaluated in farmed red-legged partridges naturally infected with the nematodes Aonchotheca caudinflata and Heterakis gallinarum. In treated birds body condition improved, nematode egg deposition was reduced and the proportion of gravid A. caudinflata females was reduced, but not the overall worm burdens. Albendazole was found to be 36.8% and 17.1% effective against A. caudinflata and H. gallinarum, respectively. These results indicate that the anthelmintic treatment used normally in Spanish partridge farms is not effective enough to avoid the introduction of parasites into the field after release.

Abstract
The production of parasite transmission stages was investigated in the faeces of 77 farm-bred ring-necked pheasants (Phasianus colchicus). Coccidian oocysts (Eimeria sp.), and nematode eggs (Heterakis sp., and Capillaria-like eggs) were recovered before and after release but all birds were treated prior to release. Treatment with fenbendazole significantly reduced the abundance of transmission-stage excretion for all parasites, and reduced the prevalence in the case of Eimeria sp. and Heterakis sp. Nonetheless, a significant increase in the excretion abundance for all parasites and in the prevalence of Eimeria sp. and Heterakis sp. was found after release. Eggs of Ascaridia sp. were found only after releasing, suggesting infection ocurred in the wild. A negative relationship was found between the pheasant body condition and Heterakis excretion abundance and a higher abundance of Capillaria sp. eggs in female birds. No significant relationship was found between parasite excretion abundance and pheasant survival. Despite this, results suggest that an increase in the excretion of parasite transmission stages follows the release of captive pheasants into the wild. This can in part explain restocking failures, but also means that autochtonous free-living birds may become exposed to new and potentially harmful pathogens. To avoid these risks it is proposed that improved prophylactic measures should be taken.

Abstract
The present study was conducted to estimate the prevalence of metallo-beta-lactamases in 91 consecutive carbapenem resistant Pseudomonas aeruginosa isolates, recovered from inpatients at Hospital de Clínicas in Buenos Aires. Both, phenotypic and genotypic methods detected the presence of carbapenemases in 10 (11%) isolates, corresponding to VIM-11 in 7/10 and VIM-2 in the others. Codifying genes were all included in class 1 integrons, upstream genes coding for aminoglycoside modifying enzymes. One hundred percent sensitivity and specificity was achieved by the metallo-beta-lactamases phenotypic screening method using EDTA (1 micromol) disks in the Pseudomonas aeruginosa isolates included in this study. Sensitivity to aztreonam in carbapenem resistant isolates was suspicious of the presence of these enzymes.

Abstract
BACKGROUND Frontotemporal dementia with parkinsonism is often linked to chromosome 17 and is related to mutations in the MAPT gene. In some families the genetic basis is still unknown. The authors report two pedigrees with FTDP-17 harboring a novel mutation (K317M) in exon 11 in the MAPT gene. METHODS The authors identified two apparently unrelated pedigrees with an autosomal dominant neurodegenerative condition. Thirteen patients were examined and eight autopsies were performed. RESULTS Mean age at onset was 48 years. Mean disease duration was 6 years. Dysarthria often heralded the disease. All cases had parkinsonism and pyramidalism and half of them had amyotrophy. Behavioral or personality changes were not a prominent feature. Cognitive decline appeared late in the evolution. Neuropathologically, a massive degeneration of the substantia nigra without Lewy bodies was a constant finding. A variable degree of frontotemporal atrophy was found. Corticospinal tract degeneration and anterior horn neuron loss were present in six of seven autopsies in which the spinal cord was examined. An extensive deposition of abnormal tau protein in a mixed pattern (neuronal, glial) was observed. Pick's bodies were not seen. Biochemical analysis of tau revealed two bands of 64 and 68 kDa. CONCLUSION Genetic analysis revealed the same novel mutation (K317M) in exon 11 of the MAPT gene in both pedigrees. A common haplotype between members of the two pedigrees suggests that they belong to the same family.

Abstract
INTRODUCTION Clinical outcomes of Parkinson's disease patients treated for 12 months with STN-DBS were analyzed. PATIENTS ADN METHODS: Twelve patients were selected using the CAPSIT protocol criteria and placement of electrodes in the appropriate target was performed according to results of fusion image techniques and intraoperative microrecording. RESULTS A reduction in motor UPDRS (44 %) and activities of daily living (58 %) scores during <<off>> phases were observed. <<On>> time with dyskinesias was reduced (86 %), while severe dyskinesias disappeared. Levodopa dosage was also lowered (44 %). Patients and caregivers showed a clear-cut benefit on quality of life (58 % and 61 % respectively). No cognitive deterioration was observed and morbidity was in the same range as that published by other teams. CONCLUSION Bilateral STN-DBS is an effective symptomatic therapy for complicated Parkinsońs disease patients. It improves the quality of life of patients and their caregivers and allows a reduction of levodopa dosage.

Abstract
The rhabdoid malignant tumor was individualized by Haas et al. as an independent entity within the kidney malignant neoplasms in 1981. From its histopathological characteristics, different cases of rhabdoid extra-renal tumor were documented. This aspect has been also recognized in a wide heterogeneous group of tumors (carcinoma, melanoma, mesothelioma and mesenchymal tumors). The diagnosis of extrarenal rhabdoid tumor is based on the presence of a proliferation of epithelioid cells with large nuclei, prominent nucleoli, abundant eosinophilic cytoplasm, and conspicuous cytoplasmic intermediate filaments, which compress the nuclei. In this article we present the case of a 50-year-old male patient with a malignant maxillary tumor with characteristic rhabdoid features. Its differential diagnosis will be discussed. The literature will also be reviewed.

Abstract
BACKGROUND Blomia tropicalis is a mite that is one of the most important causes of allergic sensitization in studies of tropical and subtropical regions. Nonetheless, there are no published studies of the sensitivity and specificity of B. tropicalis extracts. METHOD An open, non-randomized study was carried out in 205 asthmatic children and in 205 non-asthmatic children, both groups with an age range of 1 to 14 years. Duplicate skin prick tests were made using allergen extracts standardized by biological units and positive and negative controls. The test was considered positive when the average diameter of the wheal was > or = 3 mm and negative when it was < 3 mm. The validity of the test was estimated by calculating sensitivity, specificity, and the positive and negative predictive values. RESULTS The skin prick test was positive in 82.92% of the asthmatic children and in 10.7% of the non-asthmatic children, yielding a sensitivity of 82.9%, 95% CI 76.9; 87.7 and a specificity of 89.3%, 95% IC 84.0; 93.0. The positive predictive value was 88.5%, 95% IC 83.0; 92.5 and the negative predictive value was 83.9%, 95% IC 78.2; 88.4. CONCLUSIONS Blomia tropicalis is an important cause of bronchial asthma among the children of the northern Camagüey region.

Abstract
Haemophilus influenzae B(Hib) is often associated with serious systemic infections in children under 5 years of age. Since 1993, it is the most frequent agent isolated in meningoencephalitis. All the strains isolated in the country have been characterized in the National Reference Laboratory at the "Pedro Kourí" Tropical Medicine Institute. Results revealed that 97% of strains isolated from bacterial meningoencephalitis in Cuba during the period 1993-1995 corresponded to serotype B, 0.6% to serotype A and 2.4 not belong to any serotype. The classification of serotype B-strains into biotypes proved that 76% was biotype I and 21% biotype II, 8 to biotype III and 1.2% was biotype V. This study found the following resistance to ampicillin 40%, to chloranphenicol 43.3%, sulpha metoxazol 36%, trimetroprim 37.3% and tetracycline 31%.

Abstract
The possibility of detecting HIV-1 antibodies by an immunoblotting kit is studied in a panel of 125 known specimens of dried blood spotted on filter paper and their corresponding serum samples. No differences were observed in the patterns of bands with both types of samples or in the sensitivity and specificity, where 100% figures were attained, allowing to conclude that the blood specimen taken on filter paper may be used for the detection of HIV-1 antibodies by the DAVIH-BLOT system and may be kept at 4 degrees C during 30 weeks.

Abstract
UNLABELLED Accurate estimation of biodistribution and absorbed dose to normal organs and tumors is important for immunoscintigraphic studies and radioimmunotherapy treatment planning. METHODS Four patients (3 men, 1 woman; mean age 54.8 +/- 9.2 yr; range 42-64 yr) were administered 3 mg of anti-human epidermal growth factor receptor (anti-hEGF-r) antibody (ior egf/r3), radiolabeled with 99mTc activity of 39.5 +/- 1.1 mCi (range 38.5 mCi-40.7 mCi) by intravenous bolus infusion. After administration, blood and urine samples were collected from three patients up to 24 hr after injection. Whole-body anterior and posterior scans were obtained at 5 min and 1, 3, 5 and 24 hr after injection. Using a computer program, regions of interest were drawn over the heart, liver, spleen, bladder and tumor to measure the activity in the source organs at each scanning time. Time-activity curves for each source organ were then fitted to monoexponential or biexponential functions by nonlinear least squares regression using the flexible polyhedrals method, which adequately fit our data with the correlation coefficient of 0.985 +/- 0.013, and were integrated to determine organ residence times. The mean absorbed doses to the whole body and various normal organs were then estimated from residence times and from blood and urine samples using the methods developed by the Medical Internal Radiation Dose Committee. The effective dose equivalent and effective dose were calculated as prescribed in ICRP Publication Nos. 30 and 60. RESULTS Plasma disappearance curves of 99mTc-labeled anti-hEGF-r antibody were best-fit by a two-compartment model in all patients with a distribution half-life (t(1/2alpha)) of 0.207 hr +/- 0.059 hr (mean +/- s.d., n = 3) and an elimination half-life (t(1/2beta)) of 13.9 hr +/- 2.2 hr. Among the various organs, significant accumulation of the radiolabeled antibody was found in the liver (48.5% +/- 4.4%, mean +/- s.d.), heart (3.50% +/- 0.17%) and spleen (3.1% +/- 1.8%) at 5 min postadministration. These values were reduced to 3.2% +/- 0.4%, 0.1% +/- 0.01% and 0.1% +/- 0.1%, respectively, at 24 hr. Mean cumulative urinary excretion of 99mTc-labeled anti-hEGF-r antibody was 4.6% +/- 0.6% at 24 hr postinjection. Estimates of radiation absorbed dose to normal organs in rad/mCi administered (mean +/- s.d., n = 4) were: whole body 0.017 +/- 0.002; gallbladder wall 0.074 +/- 0.007; spleen 0.136 +/- 0.076; and liver 0.267 +/- 0.036. The effective dose equivalent and effective dose estimates for adults were 0.041 +/- 0.008 rem/mCi and 0.027 +/- 0.004 rem/mCi administered. CONCLUSION This feasibility study indicates that 99mTc-labeled anti-hEGF-r antibody (ior egf/r3) can be used safely; this analysis provides a dosimetric framework for future studies. This monoclonal antibody, labeled with 188Re, could possibly permit a successful regional radioimmunotherapy of tumors of epithelial origin.
