Impact of crestal and subcrestal implant placement upon changes in marginal peri-implant bone level. A systematic review.

BACKGROUND: To systematically assess studies analyzing peri-implant bone loss in implants placed in crestal and subcrestal position. MATERIAL AND METHODS: Following the recommended methods for systematic reviews and meta-analyses (PRISMA), an electronic search was conducted in the PubMed (MEDLINE), EMBASE and LILACS databases to identify all relevant articles published up until April 2017. The search included human studies comparing marginal bone loss (MBL) between a control group and a study group with a minimum of 10 patients and a minimum follow-up of 6 months after prosthetic loading with rough neck implants. Two independent reviewers assessed the risk of bias in the selected studies based on the Newcastle-Ottawa scale for observational studies and the Cochrane Collaboration for clinical trials. RESULTS: Of 342 potentially eligible items, 7 complied with the inclusion criteria. One article was retrieved through the manual search. Eight articles were finally included: five experimental and three observational studies. The risk of bias assessed by the Cochrane Collaboration and Newcastle-Ottawa showed a high risk of bias. The mean follow-up period was 21 months (range 6-36 months). In four studies, implants placed in a crestal position presented higher MBL than subcrestal implants - the differences being significant in one study, while in three studies, implants placed in a subcrestal position presented greater MBL than crestal implants, with significant differences in only one study. CONCLUSION: Despite its limitations, the present systematic review did not find better outcomes between crestal and subcrestal implant placement, however, new studies will be needed, involving improved designs and the standardization of protocols to allow statistical comparisons and the drawing of firm conclusions.

Ma-Pi 2 macrobiotic diet and type 2 diabetes mellitus: pooled analysis of short-term intervention studies.

The macrobiotic, Ma-Pi 2 diet (12% protein, 18% fat and 70% carbohydrate), has shown benefit in adults with type 2 diabetes mellitus (T2DM). This pooled analysis aims to confirm results from four, 21-day intervention studies with the Ma-Pi 2 diet, carried out in Cuba, China, Ghana and Italy. Baseline and end of study biochemical, body composition and blood pressure data, were compared using multivariate statistical methods and assessment of the Cohen effect size (d). Results showed that all measured indicators demonstrated significant changes (p < 0.001); most of them with a very high (d ≥ 1.30), or high (d = 0.80-1.29) effect size. The global effect size of the diet was Italy (1.96), China (1.79), Cuba (1.38) and Ghana (0.98). The magnitude of the individual effect on each variable by country, and the global effect by country, was independent of the sample size (p > 0.05). Similarly, glycemia and glycemic profiles in all four studies were independent of the sample size (p = 0.237). The Ma-Pi diet 2 significantly reduced glycemia, serum lipids, uremia and cardiovascular risk in adults with T2DM. These results suggest that the Ma-Pi 2 diet could be a valid alternative treatment for patients with T2DM and point to the need for further clinical studies. Mechanisms related to its benefits as a functional diet are discussed.

[Family planning in men and women with multiple sclerosis. Analysis of the Andalusian Registry (2018-2022)]. / Planificación familiar en hombres y mujeres con esclerosis múltiple. Análisis del Registro Andaluz (2018-2022).

INTRODUCTION: The Andalusian Registry of Pregnancies in patients with multiple sclerosis is the largest Spanish registry on multiple sclerosis (MS) and family planning. For the first time, it includes information on the fertility of men with MS. The influence of the use of a disease-modifying treatment (DMT) on the health of the foetus/newborn and the impact of breastfeeding on MS are also analysed. SUBJECTS AND METHODS: This is a multicentre, prospective and observational study. Recruitment of patients took place between December 2018 and December 2020. Women were followed up for one year after delivery. Altogether 100 women and 16 men were included, with a total of 103 newborn infants. RESULTS: The annualised relapse rate of the women with MS decreased significantly during pregnancy (from 0.23 to 0.065). A total of 11.2% of patients resorted to assisted reproductive techniques in order to conceive a child. No association was found between the use of a DMT at conception and/or pregnancy and the risk of miscarriage, prematurity or low birth weight. Over half the women with MS (54.2%) chose to breastfeed (26.7% of them while on a DMT). CONCLUSIONS: MS does not affect the fertility of men. Neither does the use of a DMT at the time of conception affect their fertility or their children's health. Assisted reproductive techniques did not have a negative impact on the course of MS. Breastfeeding is a common practice among women with MS and there is no evidence of positive or negative effects on disease progression.

La tasa anualizada de brotes de las mujeres con EM descendió durante el embarazo de forma significativa (de 0,23 a 0,065). Un 11,2% de los pacientes recurrieron a técnicas de reproducción asistida para conseguir la gestación. No se encontró relación entre el uso de un TME en la concepción y/o embarazo y el riesgo de aborto, prematuridad o bajo peso al nacer. El 54,2% de las mujeres con EM optaron por dar lactancia (el 26,7% de ellas usando un TME). Conclusiones. La EM no afecta a la fertilidad de los hombres. Tampoco influye en ésta, ni en la salud de sus hijos, el uso de un TME en el momento de la concepción. Las técnicas de reproducción asistida no impactaron negativamente en la evolución de la EM. La lactancia se impone como una práctica habitual entre las mujeres con EM y no se evidencian efectos positivos o negativos sobre la evolución de la enfermedad.

Application of the 2010 McDonald criteria for the diagnosis of multiple sclerosis in a Spanish cohort of patients with clinically isolated syndromes.

BACKGROUND: Recently the International Panel on Diagnosis of Multiple Sclerosis (MS) has proposed new magnetic resonance imaging (MRI) criteria for the diagnosis of MS in patients with clinically isolated syndromes (CIS). We aimed to evaluate the accuracy of these new criteria for lesions dissemination in space (DIS) and time (DIT), from a single MRI scan, to predict conversion from CIS to clinically definite MS. METHODS: We studied 67 CIS patients with baseline MRI performed within the first 3 months after onset. The follow-up was of at least 24 months. The sensitivity, specificity and accuracy of Barkhof-Tintoré criteria and the new proposed MRI criteria for DIS and DIT were calculated with SPSS v.15.0. RESULTS: The mean age for clinical onset was 30 years and 64% of patients were female. The overall conversion rate was 74%. In our cohort, Barkhof-Tintoré criteria showed a sensitivity of 71.43%, a specificity of 66.67%, with an accuracy of 73.1%. New DIS criteria showed a sensitivity of 85.71%, a specificity of 64.71% and an accuracy of 80.30%. We also evaluated the new DIT criteria with a single MRI scan in 54 patients with baseline scans that included gadolinium-enhanced images. The sensitivity of the test was 52.63% with a specificity of 75.00% and an accuracy of 59.26%. CONCLUSION: New DIS criteria are simpler and more sensitive than previous criteria. The sensitivity of DIT criterion using a single MRI scan was rather low, as other previous studies showed, reflecting its stringency, but it could improve the accuracy of early MS diagnosis in that group of patients with typical CIS and gadolinium-enhancing and non-enhancing lesions on their baseline scans. These results reinforce their use in MS diagnosis.

Restless legs syndrome in patients with multiple sclerosis: evaluation of risk factors and clinical impact.

INTRODUCTION: Restless legs syndrome (RLS) is a disorder characterised by an irresistible urge to move the legs, usually accompanied by unpleasant sensations. It is more frequent in patients with multiple sclerosis (MS) than in the general population. OBJECTIVES: To evaluate the prevalence of RLS, defined according to the 4 essential requirements included in the diagnostic criteria proposed by the International Restless Leg Syndrome Study Group, in a cohort of patients with MS; and to identify potential risk factors and the clinical impact of RLS. RESULTS: The sample included 120 patients with MS, with a mean age of symptom onset of 40 years and an average disease duration of 46 months. The prevalence rate of RLS was 23.3%. MS progression time was significantly shorter in patients with RLS (P=.001). A recent relapse, and symptoms of anxiety, depression, and neuropathic pain were significantly associated with risk of RLS (P=.001, P<.001, P<.001, and P=.001, respectively). In addition, patients with RLS had a greater risk of poor sleep quality, fatigue, daytime sleepiness, and poor quality of life than those without RLS (P=.002, P=.017, P=.013, and P=.009, respectively). CONCLUSIONS: RLS should be considered in the neurological evaluation of patients with MS; early diagnosis and treatment would improve the quality of life of patients with MS presenting RLS.

Histamine-N-methyl transferase polymorphism and risk for multiple sclerosis.

BACKGROUND: Histamine N-methyltransferase (HNMT) is the main metabolizing enzyme of histamine (a mediator of inflammation implicated in the pathogenesis of multiple sclerosis-MS) in the CNS. We have investigated the possible association between a single nucleotide polymorphism of the HNMT (chromosome 2q22.1), that causes the amino acid substitution Thr105Ile (decreasing enzyme activity) and the risk for MS. METHODS: We studied the frequency of the HNMT genotypes and allelic variants in 228 MS patients and 295 healthy controls using a PCR-RLFP method. RESULTS: The frequencies of the HNMT genotypes and allelic variants did not differ significantly between MS patients and controls, and were unrelated with the age of onset of MS, gender, and course of MS. CONCLUSION: The HNMT polymorphism is not related with the risk for MS.

Association between multiple sclerosis and Candida species: evidence from a case-control study.

Candida infection among multiple sclerosis (MS) patients has not been studied in depth. We determined whether there is an association between serological evidence of Candida infection and MS. Blood specimens were obtained from 80 MS patients and 240 matched controls. Immunofluorescence analysis and ELISA were used to detect Candida species antibodies and slot-blot to detect antigens. Using immunofluorescence analysis, moderate to high concentrations of serum antibodies to Candida famata were present in 30 (37.5%) MS patients vs. 30 (12.5%) controls (p < 0.001). Results for Candida albicans were 47.5% (38/80) in MS patients vs. 21.3% (51/240) in controls (p < 0.001), for Candida parapsilosis 37% (28/80) vs. 17.1% (41/240) (p < 0.001) and for Candida glabrata 46.3% (37/80) vs. 17.5% (42/240) (p < 0.001), respectively. After adjusting for age and gender, the odds ratios (95% confidence intervals) for MS, according to the presence of Candida antigens were: 2.8 (0.3-23.1, p = 0.337) for Candida famata; 1.5 (0.7-3.4, p = 0.290) for Candida albicans; 7.3 (3.2-16.6, p < 0.001) for Candida parapsilosis; and 3.0 (1.5-6.1, p = 0.002) for Candida glabrata. The results were similar after excluding ten patients on immunosuppressants. The results of this single study suggest that Candida species infection may be associated with increased odds of MS.

Síndrome de piernas inquietas en esclerosis múltiple: evaluación de factores de riesgo y repercusión clínica / Restless legs syndrome in patients with multiple sclerosis: evaluation of risk factors and clinical impact

Introducción: El síndrome de piernas inquietas (SPI) es un trastorno caracterizado por la necesidad imperiosa de mover las piernas, estando a menudo acompañado de sensaciones desagradables. Su frecuencia es superior en pacientes con esclerosis múltiple (EM) que en la población general. Objetivos: Evaluar la prevalencia del SPI, según el cumplimiento de los 4 requisitos esenciales incluidos en los criterios diagnósticos propuestos por la International Restless leg syndrome study group (IRLSSG, 2003), en una cohorte de pacientes con EM e identificar posibles factores de riesgo y repercusión clínica. Resultados: Se incluyeron 120 pacientes con EM, con una edad media de inicio de 40 años y un tiempo medio de evolución de 46 meses. La prevalencia de SPI, según el cumplimiento de criterios diagnósticos de la IRLSSG, fue del 23,3%. El tiempo de evolución de EM, desde la aparición de los primeros síntomas, fue significativamente menor en pacientes con SPI (p=0,001). La presencia de un brote reciente, así como de síntomas de ansiedad, depresión y dolor neuropático se asociaron de forma significativa con el riesgo de SPI (p=0,001, p<0,001, p<0,001 y p=0,001, respectivamente). Además, los pacientes con SPI y EM presentaron mayor riesgo de mala calidad de sueño, fatiga, somnolencia diurna y peor calidad de vida, que aquellos sin SPI (p=0,002, p=0,017, p=0,013 y p=0,009, respectivamente). Conclusiones: El SPI debe ser considerado en la evaluación neurológica de pacientes con EM, cuyo diagnóstico y tratamiento precoz mejoraría la calidad de vida de estos sujetos. (AU)

Se realizó un procedimiento de regeneración ósea guiada alrededor de los implantes cigomáticos para obtener un mayor grosor de la cortical vestibular y palatina alrededor de los implantes del maxilar superior y mejorar el pronóstico. A un año de la carga protésica, el hueso periimplantario se mantiene estable

A clinical case is presented in which a patient with atrophic upper jaw is rehabilitated by a combination of zygomatic implants, placed using an exteriorized approach, and conventional palatalized anterior implants. A guided bone regeneration procedure is performed around the zygomatic implants to obtain a greater thickness of the facial bone and improve the prognosis. One year after loading, the peri-implant bone remains stable

A parasitological survey of wild red foxes (Vulpes vulpes) from the province of Guadalajara, Spain.

An epizootiological survey of leishmaniosis, coccidiosis and parasitic helminths in 67 foxes (Vulpes vulpes) was conducted in Guadalajara (central Spain). Examination for parasitic protozoa revealed prevalences of 74% Leishmania (determined by molecular methods) and 2.9% coccidia oocysts (fecal flotation). Survey of parasitic helminths (fecal flotation/necropsy) demonstrated the presence of nine species, including six nematodes, two cestodes and one trematode. Nematodes were the most common parasites of foxes, followed by cestodes and trematodes. Greater levels of nematodes like Uncinaria, with a free-living stage in its life-cycle, were found in foxes in areas where moist soils were likely to exist, in contrast to areas of semiarid characteristics, where Toxascaris leonina or Trichuris vulpis were predominant. With regard to helminths of importance as human pathogens, trichinoscopy revealed the presence of a relatively high number of foxes (8.9%) infected with Trichinella spiralis. Finally, Toxocara canis infection was less frequent (4.4%) than trichinellosis.

Effects of IGF-I treatment on osteopenia in rats with advanced liver cirrhosis.

IGF-I is an anabolic hormone which has been reported to increase bone formation in several conditions of undernutrition. Advanced liver cirrhosis is associated with osteopenia and also with low serum levels of IGF-I. Previous results showed that low doses of IGF-I increase osteoblastic activity and decrease bone reabsorption in early liver cirrhosis. The aim of this study was to evaluate whether IGF-I-treatment also induces beneficial effect on osteopenia associated with advanced cirrhosis. Rats with ascitic cirrhosis were divided into two groups: group CI (n=10) which received saline and group CI+IGF (n=10) which were treated with IGF-I (2 microg/100 g bw x day, sc, during 21 days). Healthy controls which received saline were studied in parallel (CO n=10). On the 22nd day, the animals were sacrificed, and bone parameters were analyzed in femur. Posterior-anterior diameter was similar in all groups. No significant differences were observed in bone content of calcium, total proteins, collagen and hydroxyapatite in cirrhotic rats as compared with controls. However, CI rats showed significant reductions in total bone density (-13.5%, p<0.001) assessed by densitometry and radiological study. In CI+IGF rat bone density (assessed by densitometry) improved significantly as compared with CI animals. In summary, osteopenia characterized by loss of bone mass and preserved bone composition was found in rats with advanced cirrhosis induced by CCl4 and phenobarbital in drinking water. This bone disorder is partially restored by treatment with low doses of IGF-I during only three weeks. Thus, IGF-I could be considered as a possible therapy for osteopenia associated with advanced liver cirrhosis.

[Meralgia paraesthetica: a report on a series of 140 cases]. / Meralgia parestésica: a propósito de una serie de 140 casos.

INTRODUCTION: Meralgia paraesthetica is a pathology that is frequently seen in visits to extra-hospital neurology services. Nevertheless, the diagnosis, treatment and prognosis of this condition remain somewhat unclear. PATIENTS AND METHODS: A retrospective study was conducted involving 140 patients. Data were collected concerning demographic aspects, clinical picture, diagnostic study, aetiology, treatment and progression. RESULTS: There was a predominance of males, with a mean age of 54 years. The mean follow-up time was 25 months. The symptoms that were reported were as follows: numbness, burning pain, tingling or prickling in the nerve territory. Hypaesthesia was the most frequent sign found in the examination. History of another compressive neuropathy was present in 13.6% of patients. The diagnosis was based on the patient record and the neurological examination. The neurophysiological study and complementary tests were reserved for atypical cases. The most common causation was spontaneous and only three cases were found to be secondary to a structural lesion. A third of the patients were receiving pharmacological treatment. Although the clinical picture was benign, in most cases it tended to become chronic. Patients treated pharmacologically did not show a significant improvement in comparison to those who were not given treatment. The most important data for forecasting improvement of the clinical picture were the identification and correction of the factors precipitating compression of the nerve. CONCLUSIONS: Meralgia paraesthetica is a frequent, benign pathology but with a tendency to become chronic that responds poorly to pharmacological treatment. It is important to identify and correct mechanical factors and only in exceptional cases is it secondary to a structural lesion.

[Influence of the experience and of out-of-hospital stroke code in thrombolytic treatment of acute stroke]. / Influencia de la curva de aprendizaje y del código ictus extrahospitalario en el tratamiento trombolítico del ictus agudo.

INTRODUCTION: We present the experience for thrombolytic treatment using recombinant tisular plasminogen activator (rt-PA) at a university hospital. We analyze the influence of individual and collective acquired experience and of the activation of an out-of-hospital stroke code (OSC) on the delays to onset of treatment, number of patients treated and outcome. METHOD: Prospective register of patients with ischemic stroke treated with rt-PA within the period 1/2004- 12/2006. Comparison of results between patients treated during the three years of study and based on the individual experience of the neurologist who applies the treatment and on the patients treated with or without activation of OSC. RESULTS: A total of 87 patients were treated (mean age: 66.6 +/- 13.7). Door-to-needle time was 79 +/- 21 min in 2004, 64 +/-22 in 2005 and 63 +/- 26 in 2006 (p=0.003). Experienced neurologists started thrombolysis sooner (door-to-needle time: 62 +/- 22 min vs 75 +/- 27, p=0.03). Activation of the ESC reduced door-to-needle time (53 +/ 17 min vs 65 +/- 21; p=0.032) and door-to-computed tomography scan time (21 +/- 10 min vs 29 +/-24; p=0.016). There were no differences in outcome in the different groups. CONCLUSIONS: Individual and collective acquired experience and the activation of an OSC can lower in-hospital delays. This contributes to increasing the number of patients eligible for thrombolysis. Thrombolytic therapy is safe and effective even when it is applied by inexperienced neurologists if strict guidelines are followed.

Clinically isolated syndromes: a new oligoclonal band test accurately predicts conversion to MS.

BACKGROUND: Patients with a clinically isolated demyelinating syndrome (CIS) are at risk of developing a second attack, thus converting into clinically definite multiple sclerosis (CDMS). Therefore, an accurate prognostic marker for that conversion might allow early treatment. Brain MRI and oligoclonal IgG band (OCGB) detection are the most frequent paraclinical tests used in MS diagnosis. A new OCGB test has shown high sensitivity and specificity in differential diagnosis of MS. OBJECTIVE: To evaluate the accuracy of the new OCGB method and of current MRI criteria (MRI-C) to predict conversion of CIS to CDMS. METHODS: Fifty-two patients with CIS were studied with OCGB detection and brain MRI, and followed up for 6 years. The sensitivity and specificity of both methods to predict conversion to CDMS were analyzed. RESULTS: OCGB detection showed a sensitivity of 91.4% and specificity of 94.1%. MRI-C had a sensitivity of 74.23% and specificity of 88.2%. The presence of either OCGB or MRI-C studied simultaneously showed a sensitivity of 97.1% and specificity of 88.2%. CONCLUSIONS: The presence of oligoclonal IgG bands is highly specific and sensitive for early prediction of conversion to multiple sclerosis. MRI criteria have a high specificity but less sensitivity. The simultaneous use of both tests shows high sensitivity and specificity in predicting clinically isolated demyelinating syndrome conversion to clinically definite multiple sclerosis.

[Thrombolytic treatment in acute ischemic stroke in a center without previous experience. Development of internal organization and first results]. / Tratamiento trombolítico del ictus isquémico agudo en un centro sin experiencia previa. Desarrollo de la organización interna y primeros resultados.

BACKGROUND AND OBJECTIVE: Treatment of acute ischemic stroke within three hours with intravenous tissue-type plasminogen activator (t-PA) has been recently approved by the European Drug Agency. We present the development of an internal organization system that has permitted thrombolytic treatment in our center without previous experience as well as the results of the first year. PATIENTS AND METHOD: Development of the thrombolysis educational program for the staff informed, of the internal organization system, and combined care protocols among the participating services. Prospective registry of patients treated with t-PA within the period 1/2004-2/2006. We collected demographic data, stroke assessment scales score (NIHSS), time to treatment, seven day and three months mortality, symptomatic hemorrhagic transformation, systemic bleedings, functional independency at three months, early significant improvement and significant deterioration. RESULTS: Fifty-three patients were treated. Mean age: 65 +/- 13 years; 56% women. Mean NIHSS pre-treatment: 14 +/- 4.7. Mean time to hospital arrival: 62 +/- 40 minutes; door-to-treatment: 68 +/- 22 minutes, and mean time from stroke onset to treatment: 130 +/- 31 minutes. Symptomatic hemorrhagic transformation: 5.8%. Systemic bleeding: 3.8%. Seven day mortality: 5.6%; three months mortality: 15.1%. Early significant improvement: 51%. Significant neurological deterioration: 7.5%. Functional independency at three months: 51%. CONCLUSIONS: Treatment of acute ischemic stroke within three hours with intravenous t-PA is safe and is associated with a favourable outcome when it is applied by neurologists specifically trained in acute stroke management.
