ABSTRACT

Neonatal injuries produced during the childbirth or in the maneuvers of resuscitation they have a high morbidity and suppose the 8th reason of mortality in newborns. The aim of this article is to check our casuistry in the last 10 years and to present a case report of rectovaginal tear with the possible therapeutic options published in the literature. There were gathered a total of 8 perinatal neonatal injuries, being the majority of them clause-contused (5) in hairy leather, pinna and thorax. Other cases were affecting the perine: an anal tear and two rectovaginal tears; one of these patients needed colostomy and surgical repair of the perine. Only a small percentage of the perinatal neonatal injuries are valued by the paediatric surgeon. Some of them are serious and can have important consequences. The colostomy and primary or secondary closing is a therapeutic sure option in rectovaginal tears.

ABSTRACT

Endotracheal tube fire during laryngeal surgery is a rare complication but one that has serious consequences. Surgeons, anesthesiologists and others involved with this type of surgery should become familiar with how to manage this difficult situation, which should be considered a sentinel event requiring prompt analysis of the root cause and surrounding circumstances. Measures to improve management should be implemented and training provided in order to prevent the recurrence of a similar unfortunate event. We report a case in which a patient's airway caught fire during use of an electrocautery device. The patient died as a result of the lesions sustained. We report the results of the investigation and the protocols for prevention and response implemented in our surgical department, in the hope that the experience will be of interest to others working in similar settings.

ABSTRACT

INTRODUCTION: The prevalence of vesicoureteral reflux (VUR) concomitant with pyeloureteral junction obstruction (PUJO) ranges from 5.2% to 18%. Today, there is no consensus on whether routine screening should be performed or not to rule out reflux, and it can be limited to selected patients. OBJECTIVES: To study VUR prevalence in patients diagnosed with PUJO, estimate reflux levels in patients with positive study, and limit serial voiding cystourethrogram (SVCU) or ultrasound cystography to selected patients (dilated ureter at ultrasound imaging and previous UTI). MATERIALS AND METHODS: Observational, retrospective study carried out in 74 patients undergoing surgery for PUJO. Information on sex, preoperative VUR screening, results (positive or negative for VUR), and reflux levels was collected. RESULTS: 53 cases (71.6%) were male and 21 (28.4%) were female. Reflux screening was performed in 55 patients (74.3%), vs. 18 (24.3%) where no study was carried out. 16.2% of cases with VUR preoperative study were managed using ultrasound cystography. The preoperative study was positive in 6 out of the 73 patients (1 patient was excluded after being diagnosed with posterior urethral valves), which means VUR prevalence in patients already diagnosed with PUJO was 10.7%. Of the six cases, one case was grade I, two cases were grade II, one case was grade III, one case was grade IV, and one case was grade V. CONCLUSIONS: VUR has a slightly higher incidence in patients diagnosed with pyeloureteral junction obstruction than in the general population. Routine screening of vesicoureteral reflux is unnecessary, unless in case of previous urinary infection, dilated ureter at ultrasound imaging, or suspected secondary cause.


INTROUCCION: La concomitancia entre la estenosis de la unión pieloureteral (EPU) y el reflujo vesicoureteral (RVU) se sitúa entre el 5,2 y el 18%. Actualmente, no existe consenso sobre la realización de screening rutinario para descartar dicho reflujo, pudiendo limitarlo a pacientes seleccionados. OBJETIVOS: Estudiar la prevalencia del RVU en los pacientes diagnosticados de EPU. Estimar el grado de reflujo en aquellos pacientes con estudio positivo. Limitar la realización de cistouretrografía miccional seriada CUMS o de ecocistografía a pacientes seleccionados (uréter dilatado visible en ecografía, ITU previa). MATERIAL Y METODOS: Estudio observacional y retrospectivo sobre 74 pacientes intervenidos de EPU. Se ha recogido información acerca del sexo, realización de despistaje preoperatorio de RVU, los resultados (positivo o negativo para RVU) y grado de reflujo. RESULTADOS: 53 casos fueron masculinos (71,6%) y 21 (28,4%) femeninos. El despistaje de reflujo fue realizado en 55 pacientes (74,3%) frente a 18 (24,3%) en los que no se realizó ningún estudio. El 16,2% de los casos en los que se realizó el estudio preoperatorio de RVU fueron abordados mediante ecocistografía, siendo el estudio preoperatorio positivo en 6 pacientes del total de 73 estudiados (un paciente fue excluido por ser diagnosticado de válvulas de uretra posterior), lo que sitúa la prevalencia de RVU en pacientes ya diagnosticados de EPU en un 10,7%. De estos, un caso fue de grado I, dos grado II y un caso grado III, IV y V, respectivamente. CONCLUSIONES: El RVU en pacientes diagnosticados de estenosis de la unión pieloureteral presenta una incidencia ligeramente mayor que en la población general. El screening rutinario del reflujo vesicoureteral es innecesario, debiendo realizarse en casos que presenten infecciones urinarias previas, visualización del uréter dilatado en la ecografía o sospecha de causa secundaria.

ABSTRACT

This work describes the use of a new dedicated laboratory-made micro X-ray diffraction system for detecting the phases present in cross-sections of artworks. As an example, the phases present in samples from gilding ceramics and stone sculptures from the heritage of Seville (Spain) were successfully detected using this new system, which takes advantage of various devices developed for synchrotron radiation, and is complemented by the information provided by other techniques.

ABSTRACT

Illuminated Arabic manuscripts have been studied, employing two laboratory-made X-ray diffraction (XRD) systems developed recently in the C2RMF laboratory. The validity of the micro-XRD and XRD portable systems for the study of this type of artworks has been demonstrated. A common observation in all the analyses is the presence of calcite and rutile; also, hematite, goethite, cinnabar, brass, anatase and barite were detected in the various colours. Differences between the results obtained by both techniques due to acquisition mode are discussed. In addition, other techniques such as X-ray fluorescence (XRF) and micro-Raman were used for the complete characterization of the manuscripts.

ABSTRACT

Citrus greening or huanglongbing (HLB) is the main threat to the European citrus industry since one of its vectors, the African citrus psyllid, Trioza erytreae, has recently become established in mainland Europe. In this context, classical biological control programmes should be implemented to reduce the spread of the psyllid. The aims of this study were to: i) disentangle the parasitoid complex of T. erytreae combining morphological and molecular characterization; and ii) to study the biology of its main parasitoids in its area of origin in South Africa for their future importation into Europe. The main citrus producing areas of South Africa were surveyed during 2017. In contrast to previous studies, the parasitoid complex of T. erytreae included three species of primary parasitoids: Tamarixia dryi, Psyllaephagus pulvinatus and another parasitoid of the genus Tamarixia. Molecular analysis showed that it is a new species closely related to T. dryi. Tamarixia dryi was the most abundant parasitoid but its relative abundance varied among sampling sites. The sex ratio (males/females) of T. dryi and Tamarixia sp. decreased with T. erytreae size and became female biased when psyllid nymphs were larger than 0.6 and 1.2 mm2, respectively. These parasitoids were attacked by three species of hyperparasitoids, Aphidencyrtus cassatus, Marietta javensis and a species of the genus Aphanogmus. Aphidencyrtus cassatus, the most abundant hyperparasitoid, tended to emerge from large nymphs, and adult females lived as long as those of T. dryi. The implications of these results are discussed within the framework of the introduction of T. dryi into Europe.

ABSTRACT

OBJECTIVE: To report the experience of peripheral insertion of double-lumen central catheters (PIDLCC) in preterm and term newborn infants and to analyze the technical characteristics of the procedure and any observed complications. STUDY DESIGN: Retrospective review of 61 newborns that had a PIDLCC between 2003 and 2006. The study comprised clinical data analysis, anthropometrics, indications, duration, complications and reasons for withdrawal of the catheters. RESULT: Weight of the patients was <1 kg in 10%, and >2 kg in 75%. Catheters tip placement was as aimed, mostly superior cava vein (SCV), in 65.5%, and subclavian vein in remaining 34.5% and average duration of catheterization was 13.5+/-9.6 and 8.9+/-5.8 days, respectively. Blood sampling through both lumens was possible especially when the tip was at SCV. Reasons for catheter withdrawal were end of indication (45.9%), phlebitis/edema (21.3%), suspected infection (3.2%), accidental withdrawal (3.2%) and rupture of proximal end (3.2%). In three (4.9%) patients, withdrawal was due to serious complications (two cases of pleural leakage of infusion fluid and one breakage of the metallic guide). About 16.3% of the patients died with the catheter still in situ. Infection findings were positive tip culture (14.7%) and catheter-related sepsis (3.2%). CONCLUSION: Insertion of PIDLCC is possible in neonates. The incidence of complications, mostly mechanical, requires careful evaluation of indications, and strict adherence to the procedure of insertion and manipulation.

ABSTRACT

INTRODUCTION: Obstetrics and Perinatal Care has improved in the last few years. As a result there has been a significant increase in preterm babies and longer survival. The risk of abnormalities in their development is high; they need follow up, prompt action and prevention from the neonatal period. MATERIAL AND METHODS: We evaluated 116 preterm babies, birth weight less than or equal to 1,000 grams, admitted to our Unit over 5 years. Seventy five neonates survived after the neonatal period (64.7 %). We studied the development during the first three years of life. RESULTS: The number of admissions of extremely low birth weigh infants has increased by 100 % in the last five years and the survival has increased by 15 %. Failure to thrive was the most frequent problem; in the first 2 years of life neonatal growth retardation was present in more than 50 % of cases (58 % 1st year, 57 % 2nd year, 40 % 3rd year). Catch-up growth occurred except in infants who had intrauterine growth retardation. Motor function disorders were the most serious; minor alterations in this system were the most frequent but usually did not compromise the life of the patient. Cerebral palsy was present in 14 % in the 1st year of life, 17,4 % 2nd year and 19 % 3rd year. Retinopathy of prematurity was very high in our group (74 %), but ophthalmic sequela were infrequent (3.2 % 1st year, 3.9 % 2nd year, and 3.4 % 3rd year); similarly with hearing function (deafness 2.0 %). Only some mild or moderate language development delay was present and psychomotor development was normal in the majority of cases and those who were retarded improved with time. CONCLUSIONS: Nowadays there is a significant increase in the incidence and survival of extremely low birth weigh infants. They have a higher risk of abnormal development. The most frequent problem is failure to thrive and the most serious is cerebral palsy. Major ophthalmic and hearing sequela are rare. Psychomotor and language development is normal in the majority of these patients.

ABSTRACT

OBJECTIVE: To design and implement a registry of infants weighing less than 1,500 g at birth in Spain. MATERIAL AND METHODS: Prospective, cohort, multicenter study. All live born infants weighing less than 1,500 g in several voluntarily participating neonatal units in public and private hospitals were included. RESULTS: In the first 4 years of the registry (2002 to 2005), 9,638 very-low-birth-weight infants were born in the 65 neonatal units that have so far joined the program. CONCLUSIONS: The goal of very-low-birth-weight infant databases is to try to improve the quality and safety of the medical care given to these newborns and their families. This type of program helps to coordinate and promote several areas, including those of health education, training of medical staff, research and development, surveillance and quality improvement.

ABSTRACT

INTRODUCTION: Postsurgery pain is a common complaint in children and significant postoperative pain may last for weeks. Severe perisurgery pain may aggravate long-lasting negative effects. In order to prevent harmful effects, children should be provided with effective-secure analgesia. The aim of this work was to determine current practice of postsurgery pain management in children. MATERIAL AND METHODS: An observational prospective study in pediatric patients undergoing surgery in our hospital was performed. Children's (< 14 years old) having elective major surgery and outpatient surgery were collected prospectively. Clinical stage, surgery and anaesthesia procedures, postsurgery analgesia and perioperative complications were recorded. Pain control was measured by an analogic visual scale (AVS) before surgery, in post-anaesthesia recovery unit (PARU), in one-day unit (ODU) and 24 h after surgery (24hU). STATISTICAL ANALYSIS: mean values +/- sem or SD, frequency and percentage of incidence of N cases, t-test, ANOVA of one and several ways, chi-square, correlations of two variables, linear and logistic regressions depending of variables' types. RESULTS: 77 patients with mean age of 5 years old and mean weight of 22 kg were studied. The most frequently employed anesthetic technique was the general one. Forty per cent of the patients were pre-medicated with midazolam. Little pain before surgery is observed and after surgery it is moderate. Anxiety is higher after surgery and immediately after it in the recovery room or the Post Anesthesia Care Unit (PACU), subsequently it diminishes, especially patients with same-day admission surgery. Positive correlations between pain and anxiety intensities were found in each determination done. CONCLUSIONS: Is observed that pain and anxiety round surgery in children had insufficient treatment, reason why we think we should make treatment protocols, adapted at this population, its necessities and the different types of procedures they can be subjected.

ABSTRACT

The pigments, execution technique and repainting used on the polychrome wood ceilings and doors in the Casa de Pilatos (Seville, Spain) were studied using portable X-ray fluorescence equipment. Cross-sections of small samples were also analysed by optical microscopy, SEM with EDX analysis, micro-Raman and micro-infrared spectroscopy and X-ray diffraction. These carpentry works are magnificent examples of the Mudéjar art made in Spain in the early 16th century. Portable X-ray fluorescence gave good information on the different components of the polychrome. The SEM-EDX study of the surfaces of small samples gave information on their components and also characterized the compounds that had been deposited or formed by environmental contamination or by the alteration of some pigments. The SEM-EDX study of cross-sections facilitated the characterization of all layers and pigments from the support to the most external layer. The following pigments were characterized: red (cinnabar/vermillion, lead oxide, iron oxides and orpiment/realgar), black (carbon black), white (white lead and titanium barium white), yellow-orange-red-brown (orpiment/realgar and iron oxides), green (chromium oxide), blue (indigo blue and ultramarine blue), and gilding (gold leaf on bole). False gold, bronze and brass were also found. The pigments were applied with the oil painting technique over a support layer that had been primed with animal glue. This support layer was gypsum in some cases and white lead in others. This study is essential to the polychrome conservation of the studied artwork, and it will help clarify uncertainties in the history and painting of Mudéjar art.

ABSTRACT

Delottococcus aberiae De Lotto (Hemiptera: Pseudococcidae) is the latest exotic mealybug species introduced in citrus in the Mediterranean basin. It causes severe distortion and size reduction on developing fruits. Due to its first interaction with citrus, D. aberiae economic thresholds are still unknown for this crop and the current Integrated Pest Management programs have been disrupted. The objectives of this study were to determine the aggregation patterns of D. aberiae in citrus, develop an efficient sampling plan to assess its population density, and calculate its Economic and Economic Environmental Injury Levels (EIL and EEIL, respectively). Twelve and 19 orchards were sampled in 2014 and 2015, respectively. At each orchard, population densities were monitored fortnightly in leaves, twigs, and fruit, and fruit damage was determined at harvest. Our results showed a clumped aggregation of D. aberiae in all organs with no significant differences between generations on fruit. Fruit damage at harvest was strongly correlated with fruit occupation in spring. Based on these results and using chlorpyrifos as the insecticide of reference, the EIL and EEIL were calculated as 7.1 and 12.1% of occupied fruit in spring, respectively. With all this, we recommend sampling 275 fruits using a binomial sampling method or alternatively, 140 fruits with an enumerative method bimonthly between petal fall and July.

ABSTRACT

This paper reports on the effect of sonication on two mica samples. The materials have been investigated in terms of structure modifications, particle size and morphology, specific surface area and thermogravimetric behaviour. The effect of the mica structure, namely density and distribution of cations over the octahedral sites, on the sonicated products is reported. Sonication produces delamination and reduction of lateral size of the original macroscopic materials yielding nanometric flakes that retain the structure of the material, unlike other procedures previously reported in literature, such as dry grinding, that produces severe structural damage.

ABSTRACT

The recommendations in this document describe the current indications for inhaled nitric oxide (iNO) treatment in the newborn and clearly distinguish between those supported by scientific evidence and those for which evidence is still lacking, such as its use in preterm infants. The methodology for iNO administration, its dosage and the main secondary effects are discussed, and the reasons for lack of response to this treatment are analyzed.

ABSTRACT

OBJECTIVES: To determine morbidity at 2 years' corrected age in a cohort of neonates with a birth weight of less than 1,500 g born in 1999-2000 in a tertiary hospital in the Autonomous Community of Madrid. PATIENTS AND METHODS: An observational longitudinal follow-up study was performed in a cohort of 213 infants with a birth weight of < 1,500 g. Of these, 188 (87%) completed the 2-year follow-up. Various types of neurosensorial disability were studied, paying special attention to the main impairments: vision, hearing and motor impairment, and low development quotient. RESULTS: Among the patients initially included in the study, 87% completed the follow-up; 17.1% had one or more major sequela. We found one case (0.4%) of bilateral neurosensorial deafness and one case of bilateral blindness. At the age of 2 years, 5.8 % (11/188) had cerebral palsy, 14.9% had a development quotient below 85 and 18% had not reached the 3rd percentile for weight. Factors of poor neurological prognosis were subnormal head size at the age of 2 years and white matter disease (including persistent intraparenchymal periventricular echodensity and ventriculomegaly or irregular shape) as ultrasound findings. CONCLUSIONS: Less than a fifth of the very low birth weight infants presented severe sequelae at 2 years of follow-up. Factors of poor neurological prognosis were subnormal head size at 2 years and the presence of white matter disease on ultrasonography. The findings on growth and development were worrying, since 18 % of the patients had not reached the 3rd percentile for weight at 2 years' corrected age.

ABSTRACT

The malate-citrate cycle was studied during aerobic glycolysis and glutaminolysis in a strain of Ehrlich ascites tumor cells which showed a very low malate-aspartate shuttle system activity. The experimental approach includes: estimation of mitochondrial NAD[P]+-dependent malic enzyme activity; respiratory activity of freshly harvested or fasted cells, and of isolated mitochondria; and determination of the metabolites involved in the glycolytic and glutaminolytic pathways. The results suggest that in this strain, the malate-citrate shuttle is not an effective pathway for transferring glycolytic reducing equivalents from cytosol to mitochondria. Less than 15% of the glucose uptake was affected by the 1,2,3-benzenetricarboxylate inhibition of the malate-citrate shuttle. Moreover, in the presence of glucose, the malate-citrate cycle did not appear to play an important role in the glutaminolytic process. The present work supports and extends the finding of previous studies, since the results showed that the glucose metabolism depressed the oxidative processes in Ehrlich ascites tumor mitochondria, not only alone, but also in the presence of glutamine. Interestingly, the high glutamine uptake was maintained in the presence of glucose.

ABSTRACT

We report on a 35-week gestation female fetus with Hutchinson-Gilford progeria (HGP). This patient, who is the first reported with neonatal HGP in the English literature but is the fourth, counting three previous French cases, supports the existence of a more severe prenatal form of progeria. She died 7 hours after birth and presented with intrauterine growth retardation, premature aging, absence of subcutaneous fat, brachydactyly, absent nipples, hypoplastic external genitalia, and abnormal ear lobes. The child's combination of clinical and skeletal manifestations differentiates this form of HGP from other progeroid syndromes with neonatal presentation. We also report previously undescribed autopsy findings including premature loss of hair follicles, premature regression of the renal nephrogenic layer, and premature closure of the growth plates in the distal phalanges that may be related to the aging processes in this condition. We could not find any histological data to support acro-osteolysis, which is the radiographic sign of brachydactyly. The terminal phalanges in HGP seem to be underdeveloped rather than osteolytic.

ABSTRACT

Outbreaks of gram-negative colonization (generally by antibiotic-resistant enterobacteria) are common in newborn intensive care units (NICUs), and control methods are not always effective. We studied the effectiveness of an alcohol solution of N-duopropenide (NDP) in vivo (germicidal effect on flora of teams in the NICU and the pediatric intensive care unit vs handwashing with nonantiseptic soap) and its effect on the control of a multiresistant (MR) Klebsiella pneumoniae outbreak in our NICU that had persisted for 13 months, despite the use of classic control measures. For educational purposes, we also performed 4 prevalence studies of microbial hand flora in NICU staff (two before and two after introducing NDP). The alcohol solution of NDP was highly germicidal in vivo, destroying microorganisms better than classic handwashing on the hands of 69 health care staff of our NICU and PICU. The flora in both units was reduced from an average of 63% to an average of 95%. Application of this disinfectant to the hands of health care workers after handling newborns helped to eliminate the MR Klebsiella strain in our NICU, (relative risk compared with the period preceding use of the disinfectant: 8.6, with 95% confidence intervals, 4.8-145.5). Four prevalence studies of hand microbial contamination, before and after NDP introduction in the NICU, showed a significant reduction of enterobacteriaceae, mainly MR K pneumoniae, in health care workers. In conclusion, NDP in alcohol was very effective in vivo. It proved to be a useful complementary measure to handwashing and reduced exogenous microorganism transmission in a unit with a heavy patient-care workload.

ABSTRACT

Cerebral ultrasounds were prospectively performed in 100 infants weighing 1,500 gm or less in order to evaluate the prognostic significance of ventricular dilatations and their associated findings. There was no difference in the incidence of ventricular dilatation (24%) between patients with or without periventricular hemorrhage (PVH). Although patients with PVH developed ventricular dilatation significantly earlier than infants without PVH, no differences were observed in severity, location, head circumference growth, or intracranial pressure between the groups. Ventricular dilatation was statistically related to PVH grade III and PVH with parenchymal involvement; grades moderate-to-severe of periventricular echogenicity; and cystic periventricular leukomalacia (PVL). Ventricular dilatation persisted longer than 6 weeks in 61% of infants and had irregular margins in 62%. The latter were significantly related to cystic PVL. Seventy-seven of 100 infants examined were followed until 20 months corrected age. Ventricular dilatation mainly when persistent and with irregular margins was associated with handicaps. We conclude that ventricular dilatation is frequent in very low-birth weight infants. Furthermore, its occurrence may be independent of PVH. Persistent ventricular dilatation with irregular margins, even in its mild forms, suggests a parenchymal lesion and guarded prognosis.

ABSTRACT

Four hundred and ninety-two (232 males and 260 females) randomly selected inhabitants older than 15 years of La Esperanza, a rural village of Tenerife, have been inquired about their daily alcohol intake, analyzing the relationship between this parameter and sex, age, marital status, educational level, job and smoking habit, physical signs, and biological markers of excessive ethanol consumption. One hundred and seventy-four out of them (35.4%) were teetotalers, while 318 (64.6%) consumed alcoholic beverages; 18.2% (34.1% of the males and 4.2% of the females) referred excessive ethanol consumption (more than 80 g/day and 40 g/day, respectively). Men consumed 62.3 +/- 4 g/day ethanol and women, 8 +/- 1 g/day. The distribution of the population according to the amount of ethanol consumed fits into Lederman's curve, most of the individuals being consumers of small amounts of ethanol. Male sex, middle age, married or separated status, unskilled job, sometimes unemployed, low educational level, daily drinking (mainly wine), and smoking, were all related to a higher ethanol consumption. When assessed by logistic regression, only liver enlargement, parotid swelling, retches and tremor in the morning, and hoarseness, out of the physical signs, showed independent predictive value as indicators of excessive consumption as well as serum GGT, ASAT, MCV, and urate levels out the biological markers. When all those physical and analytical signs that had previously shown predictive independent value are analyzed together, all the five physical signs (liver enlargement, parotid swelling, retches and tremor in the morning, and hoarseness) but only urate, out of the biochemical markers, showed independent predictive value.
