RESUMO
UNLABELLED: The management of lymphangioma using sclerotherapy has proven to be an effective therapeutic. Our aim was to evaluate the therapeutic efficacy of OK-432 (Picibanil) in patients with lymphagioma. METHODS: The study was performed from November 2010 to July 2011. Fifteen patients of both genders were diagnosed with lymphangioma, 12 days to 12 years old. All patients were infiltrated with OK-432. The studied variables were: previous surgery, localization, type of lymphangioma, number of effective injections, reduction of mass valued as excellent (100% reduction), good (reduction > 50%) and bad (reduction < 50%), presence of recurrence and complications. RESULTS: 40% of pacients had prior surgery and 53.3% were located in the cervical-face region. The type of macrocystic lymphangioma was present in 40% of the series, mixed type in 46.6% and microcystic type in 13.4%. The number of effective infiltrations were 3. In 6 cases (40%) the result was excellent in 5 cases (33.4%) the result was good and in 4 cases (26.6%). We had 1 recurrence (6.6%) and we haven't had complications. CONCLUSION: Injection of OK-432 in macrocystic lymphangioma and mixed had a safe therapeutic modality with satisfactory results. So it is a valid alternative to conventional surgery.

BACKGROUND: Previous studies in multiple sclerosis (MS) showed that therapeutic inertia (TI) affects 60-90% of neurologists and up to 25% of daily treatment decisions. The objective of this study was to determine the most common factors and attribute levels associated with decisions to treatment escalation in an international study in MS care. METHODS: 300 neurologists with MS expertise from 20 countries were invited to participate. Participants were presented with 12 pairs of simulated MS patient profiles described by 13 clinically relevant factors. We used disaggregated discrete choice experiments to estimate the weight of factors and attributes affecting physicians' decisions when considering treatment selection. Participants were asked to select the ideal candidate for treatment escalation from modest to higher-efficacy therapies. RESULTS: Overall, 229 neurologists completed the study (completion rate: 76.3%). The top 3 weighted factors associated with treatment escalation were: previous relapses (20%), baseline expanded disability status scale [EDSS] (18%), and MRI activity (13%). Patient demographics and desire for pregnancy had a modest influence (≤ 3%). We observed differences in the weight of factors associated with treatment escalation between MS specialists and non-MS specialists. CONCLUSIONS: Our results provide critical information on factors influencing neurologists' treatment decisions and should be applied to continuing medical education strategies.

INTRODUCTION: Despite advances in neonatal care between 20% and 63% of children with necrotizing enterocolitis (NEC) require surgery. The aim was correlation the risk factors of infants with NEC "IIB / IIIA / IIIB" Bell and the clinical, surgical and pathological findings. METHOD: In the children with diagnosis of NEC surgically treated, were analyzed of variables: clinical, surgical and pathological findings. We studied two groups: control (n=5) and NEC group (n=12). Comparisons were made between groups using the Mann-Whitney U- and the Spearman coefficient (r). To assess the risk of morbidity / mortality associated with the extent of intestinal resection we applied the Cox regression. RESULT: We found differences (p < 0.05) between control group and the NEC group regarding Bell, the mean height of villi, Chiu and the number of goblet cells. In the NEC group we find correlations (p < 0.05) from Bell, regarding Chiu (r = 0.761), resection of the colon (r = 0.687), pneumatosis / perforation (r = 1) and the mean height of villi (r = -0.878). The gut reseccion was at 26 cm (3-107). We observed a risk of 1.04 in the neonatal period (p > 0.05) of mortality or consequence post-enterocolitis associated with the extent of bowel resection. CONCLUSION: The decrease in the average height of villi, the highest level of microscopic intestinal injury and reduced goblet cell population contributes to a greater extent of intestinal resection, which favors the risk of death or developing consequence post-enterocolitis.

BACKGROUND: Multiple sclerosis (MS) is a neurological chronic disease that causes a number of physical, cognitive and emotional symptoms. The identification of these factors will allow mitigating unemployment and improve quality of life of patients. The Buffalo Vocational Monitoring Survey (BVMS) is a tool to characterize Work-Challenged patients. OBJECTIVE: To describe and analyze BVMS data in people with multiple sclerosis (PwMS) from Argentina. To study the association with physical, cognitive and psychiatric morbidity in employed patients, comparing the performance of MS Work-Challenged and MS Work-Stable patients, with and without accommodations. METHODS: 119 MS patients were administered the Argentina adaptation of the BVMS, and completed measures of physical disability, fatigue, depression, cognitive processing speed, memory and verbal fluency. RESULTS: 65.54% of the patients were employed and 19.32% were unemployed, the remaining having roles of housewife, students and disability retirees. Within the employed subgroup, 60.26% were working as employees and 39.74% were self-employed. Cognitive and clinical variables differentiate patients with and without negative events and accommodations (pâ> â0.05). CONCLUSIONS: This Spanish version BVMS is considered a new tool to monitor employment difficulties in Spanish-speaking MS patients. MS Work-Challenged had a higher depression, fatigue and worse performance in cognitive variables.

At the moment the extracorporeal membrane oxygenation (ECMO) constitutes the last link in the therapeutic one of the handling of the respiratory failure in patients with Congenital Diaphragmatic Hernia (HDC). We presented our experience. From January 2001 we arrange the ECMO in neonative UCI. 76 HDC, 13 (3 rights and 10 lefts) they have needed ECMO (one in two occasions; altogether 14 procedures). Criteria of inclusion: refractory hypoxaemia, oxigenaction index > 40 and weight > 2 kg. 5 girls and 8 boys with gestacional age between 35 and 41 weeks (average: 38) and weight when being born between 2,300 and 3,500 grams (average 2,817). In 6 cases (5 transferred from other centers) the diagnosis was posnatal. Of the 7 with prenatal diagnosis, in 4 cases fetal therapy by means of traqueal occlusion had been made. Veno-venous in 8 and veno-arterial procedure in 5. Rank of duration: 68-606 hours, average of 228.35. The surgery has been made before the ECMO in 9 cases, 2 during and 1 later. In an occasion there was no surgery. The complications have been of hemorrágico type in one patient and infectious in three cases with sudden sepsis in one. Precocious mortality has been of 6 patients and delayed the 2 (total 61%). Although this procedure has the high morbi-mortality, it is necessary to consider that is patients very badly prognosis without another alternative (with mortality of the 100%). Multicentric studies are needed to establish indicators prognoses pre and postbirthdays.

Magmas vesiculate during ascent, producing complex interconnected pore networks, which can act as outgassing pathways and then deflate or compact to volcanic plugs. Similarly, in-conduit fragmentation events during dome-forming eruptions create open systems transiently, before welding causes pore sealing. The percolation threshold is the first-order transition between closed- and open-system degassing dynamics. Here, we use time-resolved, synchrotron-source X-ray tomography to image synthetic magmas that go through cycles of opening and closing, to constrain the percolation threshold Φ C at a range of melt crystallinity, viscosity and overpressure pertinent to shallow magma ascent. During vesiculation, we observed different percolative regimes for the same initial bulk crystallinity depending on melt viscosity and gas overpressure. At high viscosity (> 106 Pa s) and high overpressure (~ 1-4 MPa), we found that a brittle-viscous regime dominates in which brittle rupture allows system-spanning coalescence at a low percolation threshold (Φ C ~0.17) via the formation of fracture-like bubble chains. Percolation was followed by outgassing and bubble collapse causing densification and isolation of the bubble network, resulting in a hysteresis in the evolution of connectivity with porosity. At low melt viscosity and overpressure, we observed a viscous regime with much higher percolation threshold (Φ C > 0.37) due to spherical bubble growth and lower degree of crystal connection. Finally, our results also show that sintering of crystal-free and crystal-bearing magma analogues is characterised by low percolation thresholds (Φ C = 0.04 - 0.10). We conclude that the presence of crystals lowers the percolation threshold during vesiculation and may promote outgassing in shallow, crystal-rich magma at initial stages of Vulcanian and Strombolian eruptions.
RESUMO
Patients with clinically isolated syndrome (CIS) by definition do not have multiple sclerosis (MS) but are at risk of developing it. While studies show earlier immunomodulating drug use is effective, treatment must consider likely patient prognosis. In this paper we review current diagnosis, prognosis, and treatment literature for patients with CIS within Latin American clinical settings. Latin American MS experts, convened by ACINDES (The Civil Association for Research and Development in Health), reviewed current CIS (and early MS) literature and drew consensus conclusions. Three subgroups addressed separate questionnaires on CIS issues: prognosis, diagnosis, and treatment. MRI can contribute to predicting MS risk in patients with CIS; in Latin America, investigation of haplotype presence associated with CIS would be appropriate. McDonald's criteria and subsequent revisions enable earlier, more accurate MS diagnosis. Type A evidence exists supporting all leading immunomodulating MS drugs for effective treatment of CIS with a high risk of conversion to MS. In conclusion, patients with CIS are usually young, with often-limited symptomatic manifestations, and must be adequately prepared to receive preventive treatment. This consensus review should contribute to the dialogue between physicians and patients.

BACKGROUND: Scarce data exist about multiple sclerosis (MS) prevalence in South America. The objective of the study is to determine the prevalence of MS in a high populated area from Argentina (Greater Buenos Aires Metropolitan area) using the capture-recapture methodology. METHODS: Greater Buenos Aires is the generic denomination that refers to the megalopolis comprised by the autonomous city of Buenos Aires and the surrounding conurbation of the province of Buenos Aires. The study was carried out taking July 1996 as the prevalence month. We used capture-recapture method to estimate the prevalence of MS cross matching registries from four MS Centers. RESULTS: A total of 803 registries were obtained from the four lists. Log-linear model for capture-recapture method was used to analyze the data. The population of the area based on the 1990 census was 12,594,974; the number of MS cases estimated amongst sources interactions were between 1833 and 2359; the prevalence estimated ranged from 14 to 19.8 cases per 100,000 inhabitants. CONCLUSIONS: This is the first study to provide epidemiological data on the prevalence of MS in a large population in Argentina (Greater Buenos Aires Metropolitan area). Further epidemiological studies will clarify the true prevalence of MS in South America.

BACKGROUND: The surgical correction of proximal severe hypospadias, especially those with penoscrotal transposition (penis buried in scrotum), represents a true challenge for paediatric surgeons. A sequential approach to their repair is widely accepted, to preserve the vascularization of the neourethra and to avoid injuries in penis covering. In our experience, we believe that all hypospadias, even those associated with penoscrotal transposition, can be repaired in one surgical time by using a vascularized flap from dorsal prepuce in one or two layers (mucosal portion for urethra and skin face for ventral island). MATERIALS AND METHODS: From 1997 until 2007, 88 patients with proximal severe hypospadias have been operated. 35 patients associated penoscrotal transposition. Since 2005, we introduced a modification consisting in drawing the incisions following the own cutaneous folds resulting from the fusion of the lateral folds in penis skin. RESULTS: We performed Duckett type urethroplasty in 10 patients, Onlay type flap in 74, Onlay with oral mucosa in 2 and vesical mucosa urethroplasty in 2 of them. The fistula rate needing surgical closure was 17% (15/88), urethral stenosis was present in 5 patients (5.7%, 1 vesical mucosa, 2 Duckett urethrolpasties and 2 Onlay flaps). Severe complications were represented by partial necrosis of the skin flap in 3 patients (3.4%) needing a reurethroplasty. 1 patient presented surgical wound infection without later problems. Before 2005, among the 22 patients with penoscrotal transposition, 5 needed a new cutaneoplasty, associated in 2 occasions to a dorsal Nesbitt plicature to obtain the complete penis alignment. From 2005 until now, None of the 13 patients presenting with penoscrotal transposition needed any posterior cutaneoplasty. The follow up goes from 1 month until 10 years (median 45 months). At present time, urine spurt shows a correct range in all cases and the penis is located out of scrotal bag except in one patient, waiting for a new plasty. DISCUSSION: In our experience, we believe that all of the hypospadias may be repaired in a unique surgical time, including those of them associated with buried penis. Modification on skin incisions design following penoscrotal lateral folds with mucocutaneous preputial flap is an excellent option both for urethroplasty and correcting penis transposition.

OBJECTIVE: This study aimed to establish a comparison between the data obtained in the renal functional study through magnetic resonance using gadolinium with diuretic (furosemide) charge (MR-Gd/F), on the one hand, and the parameters obtained with the classical diuretic renogram (DR) (differential renal function -DRF- and renographic curve -RC-), on the other hand. MATERIAL AND METHOD: 10 patients were studied, 6 male and 4 female, aged between 1 month and 6 year-old. All the patients were submitted to a MR-Gd/F and a DR. In both cases, furosemide was used as overload. The pathologies observed included syndrome of the pyeloureteral junction, polar vessel, ureter valve, ectopic ureter, duplex kidney, renal dysplasia, renal ectasy, pelvic kidney and horseshoe kidney. The percentage of gadolinium uptake was compared versus the DRF, and the MR curve was compared versus the RC. Surgical treatment was required in 5 cases and an expectancy behaviour was taken in 3 cases. Among the operated patients, the diagnosis accurry was confirmed by the surgery and the pathological study. RESULTS: A 80% consistency was found between the gadolinium uptake and the DRF. There was a 90% correlation between the MR-Gd/F curve and the RC. In two cases, the MR-Gd/F required to modify the surgical criterion -previously based on the DR- and an expectancy behaviour was taken. In 90% of the operated cases, the diagnostic assumption obtained through the MR-Gd/F coincided with the surgical and pathological findings, whereas there was a coincidence in just 60% of the cases studied through the DR (p > 0.0008). CONCLUSIONS: The MR offers a real time study: anatomical, vascular and functional. Good correlation between DR and MR with respect to: (% DRF,%Gd MR and diuretic curve). The MR demonstrates greater precision in diagnosis.The MR allows recognition of non obstructive polar vessels that can then be conservatively managed.

UNLABELLED: We report our experience in the postnatal management of congenital diaphragmatic hernia (CDH) after fetal endoluminal balloon tracheal occlusion (FETO). MATERIAL AND METHODS: Out of 19 CDH fetuses diagnosed since December 2005, 13 had a lung-to-head ratio (LHR) < 1.1 (0.86 +/- 0.11) and underwent FETO at a mean gestational age (GA) of 27.9 weeks. The balloon was removed in 3 cases through puncture in EXIT (ex utero intrapartum treatment); there were 3 trans-utero punctures, 3 fetoscopies and 3 balloons deflated spontaneously. One patient died from bleeding during the FETO procedure. Six patients were not subjected to FETO: 3 had a LHR > or = 1.4 and 3 did not come to consultation prenatally. RESULTS: Twelve babies were born after FETO at 34.9 +/- 1.7 weeks GA; 3 died before surgery from refractory hypoxia. Six needed high frequency oscillatory ventilation (HFOV), and inhaled nitric oxide (NO), one progressing to extracorporeal membrane oxygenation (ECMO), and 3 needed conventional ventilation. CDH was repaired in 9: 2 with direct sutures and 7 with prosthetic patches. Extubation was at median of 5 days (range: 2 - 40), discharge was at 30.4 +/- 16.4 days. Early complications were 1 reherniation and 2 intestinal occlusions. Two patients died after CDH repair: the ECMO case at 15 days, and an infant discharged on oxygen at home, at age 4 months. Of the non-FETO patients, four needed HFOV and NO. CDH repair was performed in 5: 3 had direct repair and 2 had prosthetic patches. Extubation was at 13.4 +/- 12.9 days and discharge was at 43.8 +/- 26.5 days. One patient died before surgery from severe cardiac malformation. Early complications were 1 reherniation and 1 hiatus hernia. Late complication was 1 reherniation at 5 months of life. There was no postoperative mortality. One patient needs oxygen at home. CONCLUSION: CDH patients with a poor prognosis undergoing FETO had postnatal outcomes similar to non-prenatally studied cases and good prognosis cases.

UNLABELLED: The main salivary glands are the submaxillary, sublingual and parotid glands. Infectious and tumoral conditions are prominent in the parotid gland whilst calculi are in submaxillary and sublingual glands. METHODS. Medical record review of 18 cases with a diagnosis of salivary calculi over a 13 year period. Data collected consisted in, clinical presentation, ultrasound (US), sialography (SG) and computarized tomography (CT), and treatment. RESULTS: 13 male and 5 female. Mean age was 7.2 years. All of them presented with pain and tenderness. Parotid gland was affected in 10 cases. An infectious cause for calculi was found in 7 while 3 presented calculi with no underlying infectious cause. Submaxillary gland was affected in 6 and sublingual in 2. No infectious condition was associated to submaxillary and sublingual calculi. Surgical treatment consisted in duct canalization for calculi removal and was performed in all patients after initial treatment with antibiotics. Neither complications nor relapse was found after surgical removal. CONCLUSIONS: Diagnosis of salivary calculi is made by clinical symptoms and imaging exams. Treatment is surgical and has to be performed after medical treatment for infection and inflamation.

AIM: The aim of this paper is to analyze our experience in different surgical techniques to perform a nephrectomy for benign renal diseases in children. MATERIAL AND METHODS: From 1993 to 2005 we have performed 98 nephrectomies. We have three groups of patients depending on the surgical technique: open nephrectomy (ON), transperitoneal laparoscopic nephrectomy (TLN) and retroperitoneal laparoscopic nephrectomy (RLN). ON was performed in 36 patients. Mean age was 3.3 years. TLN was performed in 39 patients. Mean age was 4.7 years old. RLN was performed in 23 patients. Mean age was 3.6 years old. Criteria to nephrectomy was a renographic function under 19%. We have compared the three surgical techniques in relation with surgical time and mean hospital stay. RESULTS: Mean operative time was 126.2 minutes in ON, 132.3 minutes in TLN and 134.1 minutes in RLN. Mean stay was 5.02 days in ON, 2.35 days in TLN and 1.86 days in RLN. The median hospital stay of the ON group is significantly longer than that of NLT and NR groups (p < 0.05). However, there are no differences related to surgical time between all the groups. CONCLUSIONS: Nephrectomy may be performed for benign disease in children using less invasive surgical techniques. They are associated with minimal morbidity, minimal postoperative discomfort, improve cosmesis and a shorter hospital stay. However, we haven't found differences between TLN and RLN.

Several studies in multiple sclerosis (MS) suggest a trend of increasing disease frequency in women during the last decades. A direct comparison of gender ratio trends among MS populations from Argentina remains to be carried out. The objective of the study was to compare gender ratio trends, over a 50-year span in MS populations from Argentina. METHODS: multicenter study that included patients from 14 MS Centers of Argentina. Patients with definite MS with birth years ranging from 1940 to 1989 were included. Gender ratios were calculated by five decades based on year of birth and were adjusted for the F/M born-alive ratio derived from the Argentinean national registry of births. The F/M ratios were calculated using a multivariate logistic regression per five decades by the year of birth approach. Analyses were performed using Stata 10.1. RESULTS: 1069 patients were included. Gender ratios showed a significant increase from the first to the last decade in the whole MS sample (from 1.8 to 2.7; p value for trend=0.023). The Gender ratio did not show differences considering MS subtype. CONCLUSION: our study showed a modest increase of the F/M ratio (from 1.8 to 2.7) over time among patients affected by MS in Argentina.

AIM: To evaluate the role of lung nodule surgery in pediatric cancer patients. MATERIALS AND METHODS: The records of all cancer patients (< 18 y) treated at our pediatric institution since 1993 were reviewed. Clinical data, imaging features, surgical attitude, pathology and outcome were analyzed for those patients developing lung nodules on CT scan at any time. RESULTS: Fifty-seven out of 857 (6.6%) cancer patients had lung nodules at one or more times during their disease course, totalling seventy-five episodes. The primary pathological diagnoses include: Osteosarcoma n = 17, Ewing's sarcoma n = 14, Rhabdomyosarcoma n = 5, Germ cell tumor n = 4, other sarcomas n = 4, Wilms' tumor n = 3, Neuroblastoma n = 3, Lymphoma n = 2. Twenty-nine cases had lung nodules at diagnosis; in 20 they were found during therapy; in 29 concomitant with other sites of relapse off therapy; and in 16 patients as an isolated event during follow-up. Fifty-five biopsy procedures were performed through thoracotomy, thoracoscopy or pleural effusion cytology. Metastasic disease was confirmed in 46, whereas in 9 no malignancy was found. Among the nine, five showed either normal lung tissue or scarring after tumor necrosis, and four had other benign diagnoses including: reactive inflammatory cells, pleural lymphangioma, mycobacteria infection and inflammatory pseudotumor. In 39 instances biopsy was not done either because the diagnosis could be made through specific tests, or because the nodules disappeared in a follow-up CT scan within 2 weeks, or because of disease progressing in spite of treatment. In 4 patients surgical removal of lung metastases has afforded cure. CONCLUSIONS: Lung nodule surgery plays a fundamental role in the management of patients with pediatric malignancies: it allows accurate staging, avoiding overtreatment in more than 15% of the cases, and gives a higher chance of cure in some patients.

UNLABELLED: In 1996, the prevalence of multiple sclerosis (MS) for the metropolitan area of Buenos Aires using the capture-recapture method was estimated to be between 14 and 19.8 cases per 100,000 inhabitants. The aim of this study was to update the prevalence to 2014 following the same methodology. METHODS: Gran Buenos Aires is the denomination that refers to the megalopolis comprised by the autonomous city of Buenos Aires and the surrounding conurbation of the province of Buenos Aires. The study was carried out taking December 2014 as the prevalence month. We used the capture-recapture method to estimate the prevalence of MS cross-matching registries from 6 MS Centers from the metropolitan area of Buenos Aires. Log-linear model Poisson regression was used to estimate the number of affected MS patients not detected by any of the 6 sources considered. RESULTS: 1035 registries were obtained from the 6 lists from 910 different patients detected. The population of the area based on 2010 census was 12,806,866, the number of MS cases estimated amongst source interactions were 4901. The estimated prevalence was 38.2 per 100,000 inhabitants (95% CI 36.1-41.2). CONCLUSION: The study is an update almost 20 years after the first one in the area showing a significant increase in the previous reported prevalence. Our findings are in line with previous studies performed in other regions of the world.
