Results after the application of biodegradable spacer balloons as a therapeutic option in non-repairable massive ruptures of the shoulder rotator cuff / Resultados tras la aplicación de balones espaciadores biodegradables como opción terapéutica en roturas masivas no reparables del manguito de los rotadores del hombro

Introduction: One of the most frequently treated pathologies in our department are tendon lesions that affect the rotator cuff of the shoulder. There are different types of treatment for massive or irreparable tears. For a few years, a low-invasive technique was introduced based on the placement of a biodegradable subacromial spacer. The objective of the work is to analyse the results of our experience with the use of this device (InSpaceTM).Material and method: The study collects the results obtained in 25 patients with irreparable ruptures of rotator cuff defined by RM, in which they were implanted a balloon subacromial in our centre in the period from January 2015 – until December 2017. All patients were evaluated preoperatively and one year after surgery including the visual analogue scale (VAS), the Constant test (CS) and the QuickDASH (QD). Results: Of the 25 patients, 5 patients (20%) were operated by arthroscopy and 20 (80%) By open approach (mini-open). A total of 22 patients completed the follow-up year. At 12 months, 64% of the patients obtained an improvement of at least 10 points in the CS. Patients departed from an initial average CS of 32 points that improved to 54.9 points of average in the postoperative evaluation at 12 months (average improvement 22.9 points; Value-p < 0.05). In terms of pain assessment, in our study, 87% of patients obtained an improvement of at least 2 points in the EVA at 12 months of follow-up (P-value < 0.05). Patients departed from an initial average EVA of 8.7 that improved to 3.7 points average at 12 months. 73% of the patients responded to be satisfied with the intervention and would return to the surgery.(AU)

CONCLUSIóN: The results obtained in our series to one year of follow-up speak in favour of the use of the Subacromial Balloon (InSpaceTM), as a therapeutic option available for patients with irreparable ruptures of the rotator cuff. It can be used as an interim procedure, delaying the need for more invasive surgery, or as a definitive procedure in patients medically non-candidates for reverse arthroplasty. It is important to have clear indications of this procedure in order not to make mistakes.

Distribution of Native Lactic Acid Bacteria in Wineries of Queretaro, Mexico and Their Resistance to Wine-Like Conditions.

Native lactic acid bacteria (LAB) are capable of growing during winemaking, thereby strongly affecting wine quality. The species of LAB present in musts, wines during malolactic fermentation (MLF), and barrels/filters were investigated in wineries from the emerging wine region of Queretaro, México using multiplex PCR and culture. The resistance to wine-like conditions (WLC): ethanol (10, 12, and 13%), SO2 (30 mg⋅l-1), and low pH (3.5) of native LAB strains was also studied. Five species were detected within 61 samples obtained: Oenococcus oeni, Lactobacillus plantarum, Pediococcus parvulus, Lactobacillus hilgardi, and Lactobacillus brevis. Four species (excepting L. brevis) were found in must; O. oeni and P. parvulus were ubiquitous in wine and L. plantarum and L. brevis were mainly present at the initial stage of MLF, while L. hilgardii was mostly detected at the advanced stage. Furthermore, some species detected in barrel/filter, prove them to be hazardous reservoirs. From 822 LAB isolates, only 119 resisted WLC with 10% ethanol; the number of strains able to grow in WLC with 13% ethanol decreased approximately by 50%, O. oeni being the most versatile species with 65% of resistant isolates, while Lactobacillus spp. and P. parvulus were the most strongly affected, especially those recovered from barrel/filter, with less than 10% of resistant isolates. This study evidences the presence of local strains able to be used as starter cultures, and also enabled the assessment of the risks derived from the presence of spoilage LAB strains resistant to WLC.

[IgA nephropathy (Berger's disease) in children]. / Nefropatía IgA (enfermedad de Berger) en niños.

IgA nephropathy, also called Berger's disease, is characterized by recurrent gross hematuria or persistent microscopic hematuria, together with mesangial glomerular deposits of IgA found in the renal biopsy. Seven children with IgA nephropathy were studied. Most of them presented initially with recurrent macroscopic hematuria and low or moderate-grade proteinuria, without hypertension or renal function impairment. Only one patient presented with a rapidly progressive glomerulonephritis. Four patients did not receive any treatment; one of them is in remission, one has improved and two remain with moderate proteinuria and hematuria. One patient with significant proteinuria improved after prednisone and azathioprine treatment. The patient with rapidly progressive glomerulonephritis improved his renal function after oral prednisone and intravenous boluses of methylprednisolone and cyclophosphamide.

Survival and quality of life after selective portasystemic shunts.

Selective portasystemic shunts were performed in 55 consecutive patients; 27 underwent end-to-end selective renosplenic shunt, 18 distal splenorenal shunt and 10 splenocaval shunt. Thirty-one patients were in Child's class A, 18 were in class B and 6 in class C. Hospital mortality for the whole group was 16 percent and occurred less frequently in class A than in class B and C patients. Five year predicted survival for the whole group was 59 percent. At the same period of follow-up, class A patients had a higher survival rate than those in class B and C (83 percent versus 36 percent; p < 0.01). No striking difference in 5 year survival was evident in alcoholics and nonalcoholics (52 percent versus 61 percent). After surgery, long-term portasystemic encephalopathy and bleeding were noted in 2 of 36 survivors. For class A patients, selective portal shunts offer an adequate and relative safe method for decreasing mortality due to variceal bleeding.

The effect of vitamin A fortification of sugar on the serum vitamin A levels of preschool Guatemalan children: a longitudinal evaluation.

Based on the Guatemalan program of vitamin A fortification of sugar, a longitudinal evaluation on serum retinol levels of preschool-aged children was performed. Five consecutive surveys executed every 6 months were examined, considering only children who were surveyed more than once. Thus, the changes in their serum retinol after the intervention were evaluated. Natural dietary vitamin A remained unchanged throughout. Addition of retinyl palmitate to sugar increased significantly the intake (p < 0.001). After 1 yr of fortification 76% of the children experienced an elevation of retinol. All those with initial values < 20 microgram/dl showed an increase. Mean values increased significantly, particularly for children below 20 microgram/dl whose levels changed from 16.2 +/- 2.9 to 30.2 +/- 9.7 (P < 0.00001). Those between 20 to 29 microgram/dl increased from 24.9 +/- 3.2 to 30.1 +/- 8.1 (p < 0.0003). Similar results were obtained after 2 yr. The results indicated the effectiveness of the program in raising serum retinol levels.

[Evaluation of the minilaparotomy in the diagnosis of hepato biliary diseases]. / Valoración de la minilaparatomía en el diagnóstico de padecimientos hepato-biliares.

The "minilap" an integrated procedure is described. With local anesthesia one can achieve omental and liver punch biopsy, transhepatic cholangiography, visualization of th portal venous system and at the same time determine its pressure. The procedure is carried out in the X-ray department in a short period of time and it is quite innocous for the patient. This paper reports on the results obtained by this procedure in forty patients. The anatomic diagnosis was made in the 97.5%. It leads to a precise diagnosis in all and there were not secondary complications, and no mortality at all.
