Can we correct first metatarsal rotation and sesamoid position with the 3D Lapidus procedure?

OBJECTIVE: We examine the technique and radiographic outcomes obtained with triplanar first tarsometatarsal arthrodesis (3D Lapidus) for the surgical correction of hallux valgus (HV). This procedure, apart from correcting angular deformity 1st-2nd intermetatarsal angle, HV angle, etc., is specifically intended to act on first ray pronation and place the sesamoids in their normal position, to alleviate the metatarsalgia often occurring in HV before and after surgery, possibly caused by their abnormal position. This study aims to examine the radiographic outcomes of the 3D Lapidus procedure. MATERIALS AND METHODS: Retrospective study of 37 feet operated on from April 2019 to December 2019, with a minimum 1-year follow-up (mean 420 days), using the 3D Lapidus procedure. Radiographic outcomes were evaluated. RESULTS: The intermetatarsal angle decreased from a mean value of 16.42° to 5.62° (p < 0.0001). The HV angle decreased from a mean value of 32.12° to 8.05° (p < 0.0001). The preoperative first metatarsocuneiform angle, with a mean value of 21.86°, was null after arthrodesis (p < 0.0001). The tibial sesamoid position, according to the Hardy and Clapham classification, decreased from a mean value of 4.84 to 1.27 after surgery, within normality (p < 0.0001). DISCUSSION: Correction of the deformity in a single plane is generally insufficient. It is necessary to act on the three planes of space to correct the deformity, obtain good outcomes, and avoid recurrence. CONCLUSIONS: Radiographic outcomes of triplanar correction with the 3D Lapidus procedure are excellent, achieving statistically significant differences in all parameters studied.

Impact of continuous glucose monitoring on everyday life of young children with type 1 diabetes and their parents: An evaluation of 114 families.

INTRODUCTION: The prevalence of type 1 diabetes is increasing worldwide. The advent of new monitoring devices has enabled tighter glycemic control. AIM: To study the impact of glucose monitoring devices on the everyday life of young children with type 1 diabetes (T1D) and their parents. METHODS: A questionnaire was addressed to parents of children with T1D under the age of 6 years with an insulin pump treated in one of the hospitals of the ADIM network in France between January and July 2020. RESULTS: Among the 114 families included in the study, 53% of parents (26/49) woke up every night to monitor blood glucose levels when their child had flash glucose monitoring (FGM), compared with 23% (13/56) of those whose child had continuous glucose monitoring (CGM). Overall, 81% of parents (86/108) found that glucose monitoring improved their own sleep and parents whose child had CGM were significantly more likely to report improved sleep (86% vs 73%, p = 0.006). Forty-nine percent of parents (55/113) declared that they (in 87% of cases, the mother only) had reduced their working hours or stopped working following their child's T1D diagnosis. Maternal unemployment was significantly associated with the presence of siblings (p = 0.001) but not with glycemic control (p = 0,87). Ninety-eight percent of parents (105/107) think that glucose monitoring improves school integration. CONCLUSION: In these families of children with T1D, new diabetes technologies reduced the burden of care but sleep disruption remained common. Social needs evaluation, particularly of mothers, is important at initial diagnosis of T1D in children.

Determination of calcium and parathyroid hormone levels following hemithyroidectomy.

BACKGROUND AND OBJECTIVE: Hypocalcemia is one of the main complications of thyroid surgery. We hypothesized that hemithyroidectomy may have an impact on serum parathyroid hormone (PTH) and calcium levels despite only one thyroid lobe is manipulated. The objective of this study was to analyze changes in serum PTH and calcium levels following hemithyroidectomy. METHODS: This is a prospective study of 53 patients who underwent thyroid lobectomy. The serum PTH level was determined in the preoperative period, 15 min after extraction of the surgical specimen, and 24 h and 3 weeks after surgery. Serum ionized calcium was also measured in the preoperative period and at 6 h, 24 h and 3 weeks after surgery. We assessed the postoperative calcium value and its relationship with the extent of fall in PTH levels in the postoperative period. RESULTS: None of the patients had the postoperative serum ionised calcium level less than 4 mg/dl. The decrease in postoperative calcium was statistically significant at 6 and 24 h after surgery; there was no difference at 3 weeks post-surgery. The change in post-operative serum PTH levels followed a similar trend to postoperative serum calcium levels. CONCLUSIONS: Although serum calcium level decreased after a lobectomy, it always remained above 4 mg/dl. We conclude that hypocalcaemia is rare following hemithyroidectomy.

[Acquired flat foot of the adult by posterior tibial dysfunction. Options for surgical treatment]. / Pie plano adquirido del adulto por disfunción del tibial posterior. Opciones para el tratamiento quirúrgico.

We present the possible etiopatogenic causes of posterior tibial dysfunction or painful flat foot of the adult and the cause-and-effect relationship that may exist. We also expose the gradation of the lesion and the different therapeutic options for the surgical treatment of the deformity. Since 1939, multiple articles have been published, which have been endorsed by clinical, experimental, electromyographic and biomechanical studies; publications that have been consulted and evaluated for the development of this review. In our opinion: the dysfunction of the posterior tibial is caused in principle by a failure of the plantar navicular calcaneus ligament (spring ligament), the main passive stabilizer of the internal plantar arch. This failure would, in time, mean an increase in work of the posterior tibial tendon, in itself "insufficient", which would go into fatigue, until it reached a partial or total rupture. Published work on soft-part procedures acting on the posterior tibial tendon in stage II has not had the expected result in the natural history of deformity. Arthrodesis, on the other hand, has been effective in other stages, but is associated with a loss of movement dynamics in the back foot and increased pressure on adjacent joints.

Presentamos la posible causa etiopatogénica de la disfunción del tibial posterior o pie plano doloroso del adulto y la relación causa-efecto que puede existir. También exponemos la clasificación de la lesión y las diferentes opciones para el tratamiento quirúrgico de la deformidad. Desde 1939, múltiples artículos han sido publicados, avalados por la clínica, así como por estudios experimentales, electromiográficos y biomecánicos; publicaciones consultadas y evaluadas para el desarrollo de esta revisión, según nuestro criterio: el primum movens de la disfunción del tibial posterior es ocasionado por un fallo del ligamento en hamaca o calcáneo navicular plantar (spring ligament), principal estabilizador pasivo del arco plantar interno. Este fallo supondría en el tiempo un aumento de trabajo del tendón tibial posterior, de por sí "insuficiente", que entraría en fatiga hasta llegar a la rotura parcial o total. Los trabajos publicados en relación con los procedimientos de partes blandas que actúan sobre el tendón tibial posterior en el estadio II no han tenido el resultado esperado en la historia natural de la deformidad. La artrodesis por el contrario, ha sido efectiva en otros estadios, pero está asociada a una pérdida de la dinámica del movimiento en el retropié y a un aumento de la presión en las articulaciones adyacentes.

Microplastic ingestion by Atlantic chub mackerel (Scomber colias) in the Canary Islands coast.

In recent years, due to the increasing concerns about their negative impact on wildlife and possible toxicity to living organisms (including humans), microplastics have become the subject of intense investigations. In the ocean, microplastics can be easily ingested by numerous marine organisms because of their small size (<5 mm). The Northwest African upwelling system is an important fishery area, and the present study is the first one in the region to reveal the presence of microplastic particles in the digestive tract of Atlantic chub mackerel (Scomber colias). From the 120 examined fish gastrointestinal tracts, 78.3% contained some type of microplastics, 74.2% contained fibres, 17.5% plastic fragments, and 16.7% paint. More studies are needed on fish, but S. colias is a candidate for being a good indicator of microplastic contamination in the region.

Patients with influenza A (H1N1)pdm09 admitted to the ICU. Impact of the recommendations of the SEMICYUC. / Pacientes con gripe por el virus influenza A (H1N1)pdm09 ingresados en la UCI. Impacto de las recomendaciones de la SEMICYUC.

OBJECTIVES: To evaluate the impact of the recommendations of the SEMICYUC (2012) on severe influenza A. DESIGN: A prospective multicenter observational study was carried out. SETTING: ICU. PATIENTS: Patients infected with severe influenza A (H1N1) from the GETGAG/SEMICYUC registry. INTERVENTIONS: Analysis of 2 groups according to the epidemic period of the diagnosis (2009-2011; 2013-2015). VARIABLES: Demographic, temporal, comorbidities, severity, treatments, mortality, late diagnosis and place of acquisition. RESULTS: A total of 2,205 patients were included, 1,337 (60.6%) in the first period and 868 (39.4%) in the second one. Age and severity on admission were significantly greater in the second period, as well as co-infection. With regard to the impact of the recommendations, in the second period the diagnosis was established earlier (70.8 vs. 61.1%, P<.001), without changes in the start of treatment. Patients received less corticosteroid treatment (39.7 vs. 44.9%, P<.05), more NIMV was used (47.4 vs. 33.2%, P<.001) and more vaccination was made (11.1 vs. 1.7%, P<.001), without changes in mortality (24.2 vs. 20.7%). A decrease in nosocomial infection was also noted (9.8 vs. 16%, P<.001). Patients needed less MV with more days of ventilation, more vasopressor drug use and more ventral decubitus. CONCLUSIONS: The management of patients with severe influenza A (H1N1) has changed over the years, though without changes in mortality. The recommendations of the SEMICYUC (2012) have allowed earlier diagnosis and improved corticosteroid use. Pending challenges are the delay in treatment, the vaccination rate and the use of NIMV.

Serious sequellae of the hallux valgus surgery: More options for its surgical treatment. / Secuelas graves de la cirugía del hallux valgus: opciones quirúrgicas para su tratamiento.

OBJECTIVE: The purpose of this study is to present a method for treating the serious consequences that result from failure of corrective techniques used for hallux valgus, which produces severe shortening of the first ray, and makes it difficult to perform the third rocker. MATERIAL AND METHODS: In this study, conducted in 2 hospitals in Madrid and Barcelona, an assessment was made of the clinical and radiological results of 40 cases, of which 97.5% were female. Technically it involves making a metatarsophalangeal arthrodesis after bone distraction with an external mini-fixation, and then inserting an iliac crest bone graft, stabilising it with a plate or the mini-fixator. RESULTS: The pre-operative shortening was 2.5cm. and elongation obtained was between 1.5 and 3.0cm. Clinical and radiological bone graft integration was achieved at 2-4 months, although full integration occurred after one year. Falliner and Blauth criteria were used to evaluate the results at 6 and 12 months follow-up, and using Visual Analogue Scale (VAS score/pain, scale 1-10), being favourable in 80%, and not changing over time. The failure rate was 7.5%, which included the non-integration of the graft and infection, requiring additional surgery. DISCUSSION: There are not many publications on the number and type of complication for hallux valgus surgery, or guidelines established, only the treatment by conventional fusion. The problem arises when the patient presents a severe shortening of the ray, and direct fusion would aggravate the insufficiency of the first ray and the transference metatarsalgia. In these cases, these procedures would be indicated.

Skinfold measurements at birth: sex and anthropometric influence.

Weight, length, and skinfold thicknesses were measured in 4634 term and preterm neonates. Sex and weight/length ratio were important determinants of the amount and distribution of the subcutaneous fat store at birth. Gestational age, weight, length, and other ponderal indices did not explain subcutaneous fat variability.

Relationship between flexible flat foot and developmental hip dysplasia.

PURPOSE: To evaluate the possible relationship between flexible flat foot and developmental hip dysplasia in children between six and 15 years of age. METHOD: Cross-sectional study including 65 patients that had undergone surgery due to residual hip dysplasia or hip dislocation and compared against 75 healthy patients. Flexible flat foot prevalence was measured in each group, with the results showing that 61% of the group with residual hip dysplasia or hip dislocation had this condition, vs. 12% in the healthy group. The statistical analysis shows that the chances of suffering from flexible flat foot, are five times greater in the hip dysplasia or hip dislocation group, than in the healthy group. DISCUSSION: There is no evidence in the literature showing a relationship between these two conditions, even though they have a common etiology. This study shows a potential measurable relation between this two conditions. CONCLUSION: Patients with hip dysplasia or dislocation may have a higher chance of presenting flexible flat foot during late childhood, adolescence and adulthood, a fact that suggests a relationship between these two pathologies. Also, patients who seek assistance for the first time because of a flexible flat foot condition without having been evaluated during the first year of life for hip dysplasia, would be better off if evaluated for residual hip dysplasia.

Occupational and environmental reproductive hazards education and resources for communities of color.

Little research has been published on the occupational and environmental hazards affecting people of color. Even less is known about the hazards that affect women of color. Although women of color have always been aggressive participants in the work force, their labor activity has increased dramatically over the last decade. Current job placement patterns suggest that women of color are concentrated in the lowest-paying and most hazardous jobs. In this paper, we specifically focus on occupational and environmental reproductive health concerns. We write with the understanding that reproductive hazards can affect pregnant women, nonpregnant women, and men, as well as the health and development of young children. Emphasis is placed primarily on African American women, because information on Hispanic, Native American, and Asian women is very limited. We discuss the participation of women of color in the labor force, using the U.S. Department of Labor categories. We review specific occupational hazards associated with each category of work and briefly discuss environmental hazards, noting that communities of color are at a disproportionate risk of exposure. Finally, we present the consensus report of the Community Education Working Group from the Woods Hole Conference on Occupational and Environmental Reproductive Hazards.

Lipoprotein (a) and other risk factors in patients with non-insulin-dependent diabetes mellitus.

BACKGROUND: Studies have established a relationship between lipoprotein (a) [Lp(a)] levels and cardiovascular disease, but few have studied Lp(a) in patients with non-insulin-dependent diabetes mellitus (NIDDM). METHODS: We determined Lp(a) concentrations, levels of glycated hemoglobin, and the personal and family history of atherosclerosis in 88 patients with NIDDM (53 men and 35 women; age, 33-70 years) and 90 age- and sex-matched controls. Twenty-three patients with NIDDM had cardiovascular disease (CVD group) and 65 did not (non-CVD group). RESULTS: Lp(a) levels were higher in CVD than non-CVD patients (P < 0.01). Triglyceride levels negatively correlated with Lp(a) (r = -0.51, P < 0.05), independently of the metabolic control of diabetes. Patients with poor metabolic control (glycated hemoglobin > 7.5%) had higher Lp(a) levels than the control group (P < 0.05). Lp(a) levels were higher than 0.30 milligram in 11% of patients without CVD and 55% of those with CVD (P < 0.05). Cluster analysis showed that Lp(a), as well as total cholesterol, triglycerides, apolipoprotein B100, and age were independently related to CVD in patients with NIDDM (P < 0.001 for triglycerides and P < 0.05 for the other variables). CONCLUSIONS: Lp(a) levels can be considered an independent risk factor for the development of atherosclerosis in NIDDM.

Encephalocraniocutaneous lipomatosis: neurologic manifestations.

We report a new case of encephalocraniocutaneous lipomatosis, a rare neurocutaneous syndrome of unknown etiology with involvement of tissues arising from the mesoderm and ectoderm: skin, eye, adipose tissue, and brain. We also review the neurologic manifestations of the syndrome, the most frequent of which include seizures, ventricular enlargement, calcifications, mental retardation, and cerebellopontine angle tumor. Our patient had an extensive extradural spinal cord lipomatous lesion, emphasizing the importance of screening for spinal abnormalities in asymptomatic patients with this condition.

Congenital hemihypertrophy.

We present an isolated complete left hemihypertrophy in a girl with follow-up data from birth up to the age of 5 months.

Determinants of birth size in Northeast Spain.

OBJECTIVE: To update knowledge on determinants of newborn body size in Northeast of Spain considering gestational, parental and socio-cultural variables. METHODS: Cross-sectional assessment of 1442 infants from Aragón (Spain), born at term between March 2009 and March 2010. Obstetric, neonatal, socio-demographic and parental anthropometry data were collected during the first infant scheduled health examination. Hierarchical linear regression models were used to explore associations between newborn anthropometry and included variables. RESULTS: Birth weight was significantly higher in males than in females (130.7 g), when mother did not smoke during pregnancy (126.3 g), in immigrant mothers (113.1 g) and when parity increased (67.1 g per additional birth). Body weight at birth was 16.9 g higher per kg of maternal weight gain during pregnancy, 5.4 g higher per kg of maternal pre-pregnancy weight and 5.1 g higher per cm of maternal height. Birth length was also significantly higher in males than in females (0.87 cm), when mother did not smoke (0.48 cm), in immigrant mothers (0.64 cm), and it was positively associated with parity, maternal anthropometry and paternal height. Newborn anthropometry was not associated with maternal age, educational level or living location. CONCLUSIONS: Independently of gestational age and newborn sex, the main predictors of birth weight and length were maternal pre-pregnancy anthropometry and weight gain during gestation, to smoke during pregnancy, parity and maternal origin. Our results identify potential modifiable factors influencing newborn body size.

Feeding patterns and growth trajectories in breast-fed and formula-fed infants during the introduction of complementary food / Patrones de alimentación y trayectorias de crecimiento en niños con lactancia materna y con leche de fórmula durante la introducción de la alimentación complementaria

Introduction: several investigations have identified breastfeeding as a protective factor for rapid infant weight gain and childhood obesity while other studies have found that this protective effect could be the result of confounding factors. Objectives: to assess the associations between lactation practices (breast-fed vs formula-fed infants) during the introduction of complementary food period, as well as the following: a) patterns of food intake; and b) trajectories of growth at six, nine and 12 months (z-score of weight, height and body mass index [BMI] and changes in these z-scores from six to 12 months). Methods: two hundred and three infants randomly selected from Spanish Primary Health Centres were measured. Parents recorded all infant's food consumption for three days (g/day). Linear regression models were applied. Results: breast-fed infants had a lower intake of cereals, fruit baby food, vegetables with meat/fish and a total intake of food compared to formula-fed infants at nine months of age. After adjusting for sex, parental education and total food intake, breastfed children continued to have lower intake of cereals (-5.82, 95% CI: -9.22, -2.43), and lower total food intake (-301.23, 95% CI: -348.50, -253.96). Breast-fed infants had a lower change in z-score of weight, height and BMI from six to 12 months of age and these differences remained when adjusting for all confounders. Conclusions: formula-fed infants during the complementary feeding period have a higher food intake and show higher rates of rapid infant weight gain compared to breast-fed infants. These differences in growth trajectories depending on breastfeeding maintenance and food intake during early life must be considered in adiposity risk evaluation

Introducción: varios estudios han identificado la lactancia materna como un factor protector frente a la ganancia rápida de peso y la obesidad infantil, mientras que otros estudios han encontrado que este efecto protector podría ser el resultado de la interferencia de factores de confusión. Objetivos: evaluar las asociaciones entre el tipo de lactancia (leche materna versus lactantes alimentados con fórmula) durante la introducción de la alimentación complementaria, así como: a) los patrones de ingesta de alimentos; y b) las trayectorias de crecimiento a los seis, nueve y 12 meses (z-score de peso, estatura e índice de masa corporal (IMC) y variaciones en estos z-score entre los seis y los 12 meses. Métodos: se midieron 203 neonatos seleccionados en centros de salud primaria españoles. Los padres registraron el consumo de alimentos de todos los bebés durante tres días (g/día). Se aplicaron modelos de regresión lineal. Resultados: los bebés alimentados con leche materna tuvieron una menor ingesta de cereales, alimentos para bebés a base de frutas, verduras con carne/pescado, así como una menor ingesta total de alimentos en comparación con los bebés alimentados con fórmula a los nueve meses de edad. Después de realizar el ajuste por sexo, educación de los padres y consumo total de alimentos, los niños alimentados con leche materna continuaron teniendo una menor ingesta de cereales (-5,82, IC 95%: -9,22, -2,43) y una ingesta total de alimentos más baja (-301,23, IC 95%: -348,50, -253,96). Los bebés alimentados al pecho tuvieron un menor incremento en la puntuación z-score de peso, talla e IMC entre los seis y los 12 meses de edad y estas diferencias se mantuvieron cuando se ajustaron para todos los factores de confusión. Conclusiones: los lactantes alimentados con fórmula durante el periodo de alimentación complementaria tienen una mayor ingesta de alimentos y muestran tasas más altas de ganancia de peso en comparación con los lactantes alimentados con leche materna. Estas diferencias en las trayectorias de crecimiento en función del mantenimiento de la lactancia materna y la ingesta de alimentos durante los primeros años de vida deben considerarse en la evaluación del riesgo de adiposidad

Pacientes con gripe por el virus influenza A (H1N1)pdm09 ingresados en la UCI. Impacto de las recomendaciones de la SEMICYUC / Patients with influenza A (H1N1)pdm09 admitted to the ICU. Impact of the recommendations of the SEMICYUC

OBJETIVOS: Evaluar el impacto de las recomendaciones SEMICYUC 2012 en la gripe A grave. DISEÑO: Prospectivo multicéntrico observacional. Ámbito: UCI. PACIENTES: Pacientes con virus influenza A (H1N1) grave (registro GETGAG/SEMICYUC). INTERVENCIONES: Análisis de 2 grupos según el periodo epidémico del diagnóstico (2009-2011; 2013-2015). VARIABLES: Demográficas, temporales, comorbilidades, gravedad, tratamientos, mortalidad, diagnóstico tardío y lugar de adquisición. RESULTADOS: Se incluyeron 2.205 pacientes, 1.337 (60,6%) en el primer periodo y 868 (39,4%) en el segundo. La edad, la gravedad al ingreso y la coinfección bacteriana fueron significativamente mayores en el segundo periodo. Respecto al impacto de las recomendaciones, en el segundo periodo el diagnóstico fue más precoz (70,8 vs. 61,1%, p < 0,001), sin cambios en el inicio del tratamiento. Se administraron menos corticoides (39,7 vs. 44,9%, p < 0,05), se utilizó más VMNI (47,4 vs. 33,2%, p < 0,001) y se objetivó una mayor tasa de vacunación (11,1 vs. 1,7%, p < 0,001), sin cambios en la mortalidad (24,2 vs. 20,7%). También se evidenció una disminución de la infección adquirida en el hospital (9,8 vs. 16%, p < 0,001). Asimismo, los pacientes requirieron menos VM con más días de ventilación, más vasopresores y más decúbito prono. CONCLUSIONES: El manejo de los pacientes con gripe A (H1N1) grave se ha modificado con los años, sin cambios en la mortalidad. Las recomendaciones de la SEMICYUC del año 2012 han mejorado el diagnóstico precoz y el uso de corticoides. Queda por mejorar el retraso en el tratamiento, la tasa de vacunación y la utilización de la VMNI

Maternal active smoking and newborn body composition.

OBJECTIVE: Maternal smoking during pregnancy is associated with a reduction in birth size but very few studies have collated changes in neonatal anthropometry. Our aims were both to assess body composition differences by anthropometry between new-borns from smoking mothers and those from non-smoking mothers, and to show whether these differences affect proportional body mass distribution. METHODS: Caucasian mothers and their full term singleton new-borns (N=1216) were selected during 2009. A structured questionnaire was completed regarding obstetric and demographic data, as well as tobacco consumption. Women were categorized, according to their smoking habits, into a non-smoking group (never smoked or stopped smoking prior to pregnancy) and a smoking group (smoked throughout pregnancy). RESULTS: 22.1% of mothers smoked during pregnancy (median: 6 cigarettes/day, range: l-40). Smoking mothers were significantly younger than non-smoking mothers but there were no differences regarding other aspects which could affect infant weight. Infants from non-smoking mothers were heavier, longer, and body circumferences were all larger than those from smoking mothers (p<0.001), but the Ponderal Index showed no statistical differences. Skinfold thicknesses were significantly lower in new-borns from smoking mothers but these differences were less evident than those from body size. Subcutaneous fat distribution did not show statistical differences between the two groups. After gestational age, to smoke during gestation is the second main determinant of birth weight. CONCLUSIONS: Smoking during pregnancy involves a generalized reduction of most axiological parameters as a result of proportionate fetal growth impairment. In those infants born from mothers who smoked during gestation, neonatal lean body mass appears to be more affected than body fat, and distribution of subcutaneous fat is not different.

[Prevalence of smoking and second-hand smoke exposure: differences between Spanish and immigrant pregnant women]. / Prevalencia de tabaquismo y exposición al humo ambiental de tabaco en las mujeres embarazadas: diferencias entre españolas e inmigrantes.

OBJECTIVES: To identify differences in the prevalence of smoking and second-hand smoke exposure between Spanish and immigrant pregnant women, as well as the factors associated with continued smoking during pregnancy. METHODS: An epidemiologic cross-sectional study was carried out in women attended at delivery in Zaragoza (Spain). A smoking questionnaire was used to collect the following variables: the women's and partners' sociodemographic factors and smoking behavior, second-hand smoke exposure and perception of the risks of this exposure. RESULTS: We included 2440 women (35% immigrants). A total of 31.1% smoked before becoming pregnant and 18.2% during pregnancy, with significant differences between Spanish and immigrant women (21.9% versus 8.7%; p<0.001). Immigrant women lived with a greater number of smokers, smoked more inside the home, were exposed to second-hand smoke for a greater number of hours per day, avoided public places with second-hand smoke less, and more often worked in bars and restaurants. The following factors were associated with smoking during pregnancy: being Spanish, smoking a greater number of cigarettes before pregnancy, being exposed to second-hand smoke at home for a greater number of hours, having a low perception of risks and having a partner with lower educational attainment. CONCLUSIONS: The prevalence of smoking is higher among Spanish pregnant women than immigrant women, although the immigrant population is more exposed to second-hand smoke at home and at work. There are socio-cultural differences that should be taken into account when carrying out interventions in women of reproductive age.

[Disruption of anterointernal weight bearing: sequelae of surgical treatment of hallux valgus]. / Alteración del apoyo anterointerno como secuela del tratamiento quirúrgico del hallux valgus.

Sequelae of forefoot surgery range between 30 and 40%; the most frequent ones are transfer metatarsalgia and deformity relapse. Forefoot surgery complications disrupt biomechanics. Anterointernal weight bearing alteration is most frequent, due to involvement of the metatarsal, the phalanx or both. Metatarsophalangeal arthrodesis normalizes the length of the first ray and pressure transmission. The use of this technique has made it possible to confirm pain relief, as well as improved function and a better cosmetic result, which allows the patient to wear ormal footwear.

[Impact of divorce on quality of life in children aged 8-12 years in the province of Alicante (Spain)]. / El impacto del divorcio en la calidad de vida de los niños de 8 a 12 años de edad en la provincia de Alicante.

OBJECTIVES: To examine differences in quality of life according to family structure in Spanish children for the first time, and to determine whether the quality of life of children with divorced parents differs according to perceived interparental conflict. METHOD: A cross-sectional, descriptive study was carried out in 1,025 children aged between 8 and 12 years old, recruited from seven randomly-selected schools in the province of Alicante. Of the total sample, 861 children had married parents and 164 had divorced parents. The children completed the Child Health and Illness Profile-Child Edition and those with divorced parents also provided information on the current relationship between their parents. RESULTS: Quality of life was higher in children with married parents than in those with divorced parents, with higher scores in all dimensions. Children who reported conflict between their parents after the divorce had worse quality of life. CONCLUSIONS: These results confirm significant differences in quality of life according to family structure and revealed the relationship between children's self-perceived health and interparental conflict after divorce. We emphasize the importance of health professionals in providing guidance to divorced parents on preventing their children's health problems and facilitating adaptation to the new family situation.
