Two-year follow-up of the outcomes of endoscope-assisted minimally invasive nonsurgical periodontal therapy for deep intrabony defects / 口腔疾病防治

Objective@#To explore the clinical efficacy and imaging changes of minimally invasive nonsurgical periodontal therapy (MINST) assisted by endoscopy for deep intrabony defects and to compare its effectiveness with that of traditional scaling and root planning (SRP) to therefore provide a reference for clinical periodontal treatment.@*Methods@#Patients with deep intrabony defects ≥ 4 mm in size were selected and divided into two groups: the MINST (MINST, 20 cases, 81 sites) group and the classic scaling and root planing (SRP, 20 cases, 80 sites) group. Before treatment and 12 and 24 months after treatment, probing depth (PD) and clinical attachment loss (CAL) were examined. Moreover, changes in the depth and angle of the intrabony defects were analyzed. Follow-up examination and maintenance treatment should be conducted every 3 months for 12 months after the initial treatment and every 6 months thereafter until 24 months.@*Results@#The PD and CAL of patients in both groups continued to decrease (P<0.001), and imaging examinations revealed a decrease in defect depth and an increase in intrabony defect angle (P<0.001). The changes in the first 12 months were significantly greater than those in the last 12 months in both groups (P<0.001). The decreases in PD, CAL, and depth of intrabony defects and increase in angle in the MINST group were significantly greater than those in the SRP group (P<0.001). At 12 and 24 months after treatment, the PD and CAL in the MINST group were lower than those in the SRP group (P<0.001). The defect height of the MINST group decreased more than that of the SRP group (P<0.001), and the defect angle of the MINST group increased more than that of the SRP group (P<0.001).@*Conclusion@#Minimally invasive nonsurgical periodontal therapy can significantly promote the healing of deep intrabony defects and the regeneration of alveolar bone. Imaging reflects that alveolar bone healing is rapid at first and then slows. Compared with traditional SRP, endoscopically assisted MINST can yield better clinical indicators and imaging changes in intrabony defects.

Accuracy of digital guided implant surgery: expert consensus on nonsurgical factors and their treatments / 口腔疾病防治

@#The standardized workflow of computer-aided static guided implant surgery includes preoperative examination, data acquisition, guide design, guide fabrication and surgery. Errors may occur at each step, leading to irreversible cumulative effects and thus impacting the accuracy of implant placement. However, clinicians tend to focus on factors causing errors in surgical operations, ignoring the possibility of irreversible errors in nonstandard guided surgery. Based on the clinical practice of domestic experts and research progress at home and abroad, this paper summarizes the sources of errors in guided implant surgery from the perspectives of preoperative inspection, data collection, guide designing and manufacturing and describes strategies to resolve errors so as to gain expert consensus. Consensus recommendation: 1. Preoperative considerations: the appropriate implant guide type should be selected according to the patient's oral condition before surgery, and a retaining screw-assisted support guide should be selected if necessary. 2. Data acquisition should be standardized as much as possible, including beam CT and extraoral scanning. CBCT performed with the patient’s head fixed and with a small field of view is recommended. For patients with metal prostheses inside the mouth, a registration marker guide should be used, and the ambient temperature and light of the external oral scanner should be reasonably controlled. 3. Optimization of computer-aided design: it is recommended to select a handle-guided planting system and a closed metal sleeve and to register images by overlapping markers. Properly designing the retaining screws, extending the support structure of the guide plate and increasing the length of the guide section are methods to feasibly reduce the incidence of surgical errors. 4. Improving computer-aided production: it is also crucial to set the best printing parameters according to different printing technologies and to choose the most appropriate postprocessing procedures.

Tratamiento con HeberFERON( en el carcinoma basal palpebral

El carcinoma basal palpebral representa un 90 % de los tumores malignos oculares con una alta morbilidad. Su incidencia tiene un comportamiento diferente en las distintas partes del mundo y, por lo general, aumenta con la edad. El diagnóstico positivo se realiza por la evaluación histológica de la muestra mediante biopsia escisional. El tratamiento ideal es el quirúrgico, aunque existen otras opciones de tratamiento. El no quirúrgico tiene como objetivo la eliminación del tumor, así como evitar las complicaciones o las secuelas funcionales y estéticas por la cirugía. Se reconocen numerosas opciones dentro de la modalidad terapéutica no quirúrgica; imiquimod, 5-fluorouracilo, inhibidores de la vía de Hedgehog y los interferones. Diversos estudios han demostrado la utilidad de los interferones en monoterapia o como terapia combinada, en pacientes no susceptibles de actuaciones quirúrgicas. Por esta razón, se decidió revisar la literatura científica actual sobre la eficacia y seguridad del HeberFERON® en el tratamiento del carcinoma basal palpebral. Se realizó una búsqueda actualizada teniendo en cuenta los descriptores correspondientes a las palabras clave relacionadas con la temática a investigar, en las bases de datos bibliográficas Medline (buscador PubMed), SciELO, Ebsco, Clinical Key y en Google Académico. Se recuperaron 35 artículos que su contenido respondía al tema de estudio.

Palpebral basal carcinoma represents 90% of ocular malignant tumors with high morbidity. Its incidence has a different behavior in different parts of the world and generally increases with age. Positive diagnosis is made by histological evaluation of the specimen by excisional biopsy. The ideal treatment is surgical, although other treatment options are available. Non-surgical treatment is aimed at eliminating the tumor, as well as avoiding the complications or functional and esthetic sequelae of surgery. Numerous options are recognized within the non-surgical therapeutic modality; imiquimod, 5-fluorouracil, Hedgehog pathway inhibitors and interferons. Several studies have demonstrated the usefulness of interferons in monotherapy or as combination therapy in patients not amenable to surgery. For this reason, it was decided to review the current scientific literature on the efficacy and safety of HeberFERON® in the treatment of palpebral basal cell carcinoma. An updated search was carried out taking into account the descriptors corresponding to the key words related to the subject under investigation, in the bibliographic databases Medline (PubMed search engine), SciELO, Ebsco, Clinical Key and Google Scholar. Thirty-five articles were retrieved whose content corresponded to the subject of the study.

Eficiencia de la terapia periodontal no quirúrgica en la actividad clínica de la artritis reumatoide

Introducción: El efecto del tratamiento no quirúrgico periodontal en los pacientes con artritis reumatoide es escaso y controversial. Objetivo: Evaluar el efecto de la terapia periodontal no quirúrgica en la actividad de la artritis reumatoide. Métodos: Se realizó un estudio cuasi experimental de intervención terapéutica en 30 pacientes de ambos sexos entre 35 y 70 años de edad con diagnóstico clínico de artritis reumatoide y periodontitis. Fueron incluidos en este estudio los pacientes con más de ocho dientes presentes y aprobación escrita para participar en la investigación y excluidos las embarazadas, fumadores y los que recibieron terapia periodontal o antibiótica. Los parámetros clínicos-serológicos y periodontales fueron evaluados antes y 30 días después de la terapia periodontal. Las variables estudiadas fueron: formas de periodontitis y actividad de la enfermedad reumática (DAS-28/VSG). Se utilizaron frecuencias absolutas, relativas, chi-cuadrado y correlación de Spearman al 95 % de confianza. Resultados: El grupo de edad de 45-54 años y el sexo femenino fueron predominantes. La periodontitis incipiente y moderada fue la más prevalente antes del tratamiento periodontal y estuvo asociada a los niveles de actividad moderada de la AR. Tras el tratamiento periodontal se confirmó disminuciones en el estado periodontal y en la actividad de la afección reumática en el 73.3 % de los pacientes. Conclusiones: La terapia periodontal no quirúrgica mejoró el estado periodontal y redujo la actividad de la artritis reumatoide.

Introduction: The effect of nonsurgical periodontal treatment in patients with rheumatoid arthritis is limited and controversial. Objective: To evaluate the effect of non-surgical periodontal therapy on the activity of rheumatoid arthritis. Methods: a quasi-experimental study of therapeutic intervention was carried out in 30 patients of both sexes between 35 and 70 years of age with a clinical diagnosis of rheumatoid arthritis and periodontitis. Patients with more than eight teeth present and written approval to participate in the research and excluded were included in this study: pregnant women, smokers and those who received periodontal or antibiotic therapy. The clinical - serological rheumatoid and periodontal parameters were evaluated: before and 30 days after periodontal therapy. The variables studied were: forms of periodontitis and activity of the arthritic disease. Absolute and relative frequencies, chi-square and Spearman's correlation at 95 % confidence were used. Results: The age group of 45-54 years and the female sex were predominant. Early and moderate periodontitis was the most prevalent before periodontal treatment and was associated with moderate levels of rheumatoid activity. After periodontal treatment, decreases in periodontal status and rheumatic disease activity were confirmed in 73.3 % of patients. Conclusions: Non-surgical periodontal therapy improved the periodontal status and activity levels of rheumatoid arthritis.

Evidencia de la efectividad del uso de aparatología ortopédica prequirúrgica en pacientes con labio y paladar hendido: revisión sistemática / Evidence of the effectiveness of the use of presurgical orthopedic appliances in patients with cleft lip and palate: a systematic review

Resumen El objetivo de este artículo fue evaluar la evidencia sobre el uso de una aparatología ortopédica prequirúrgica (AOP) en pacientes con labio y paladar hendido. Se realizó una búsqueda en las siguientes bases de datos: Medline/PubMed, Google Scholar, Clinical Trails.gov, ProQuest y Web of Science. En la búsqueda, se encontraron 7.926 registros, de los cuales se analizaron 105 artículos de texto completo; de éstos se incluyeron 23 estudios en pacientes con uso de AOP, asi como su grupo control sin el uso del AOP, previo al mismo tipo de cirugía. Los aparatos más utilizados para la AOP en el manejo de LPH fueron: el paladar pasivo (Paladar de Hotz), el modelador nasolaveolar (NAM), aparato McNeil y por último el T-traction; los principales desenlaces evaluados fueron: la estética facial y apariencia nasal; la evaluación de medidas cefalométricas, de vías aéreas superiores, nasales, del ancho de la fisura y así como puntos de referencia anatómicos como la distancia inter-canina e inter-tuberosidad. Además, se encontraron estudios que evaluaron oclusión y la fonación. La evidencia de esta literatura sugiere que el uso de aparatos activos tiene un mejor efecto que la placa pasiva, en términos de estética facial y aproximación de los segmentos maxilares para el cierre de la fisura. Sin embargo, la heterogeneidad, el riesgo de sesgo y la baja calidad de los estudios no permite tener conclusiones sólidas.

Abstract This review article aimed to evaluate the evidence on the use of a presurgical orthopedic appliance (POP) in patients with cleft lip and palate. The search was conducted using Medline/PubMed, Scholar Google, Clinical Trails, ProQuest, Scopus, and Web of Science databases. During the search, 7,926 records were found, of which 105 full-text articles were analyzed, and 23 studies included analysis in patients with the use of POP, and their control groups without the use of POP prior to the same type of surgery. The devices most used for POP in the management of LPH were: the passive palate (Hotz palate), the nasolaveolar moulding (NAM), the McNeil device, and finally, the T-traction. The primary outcomes evaluated were: facial aesthetics and nasal appearance; the evaluation of cephalometric measurements, upper airways, nasal fissure width, as well as anatomical references such as inter-canine and intertuberosity distances. In addition, studies that evaluated occlusion and phonation were found. The evidence from this literature suggests that the use of active appliances had a better effect than passive appliances in terms of facial aesthetics and approximation of the maxillary segments for the closure of the fissure. However, the heterogeneity, the risk of bias, and the low quality of the studies do not allow to state firm conclusions.

Clinical application progress on the diode laser in nonsurgical periodontal treatment / 口腔疾病防治

@#Chronic periodontitis is a chronic inflammatory disease caused by plaque microorganisms, and removal of plaque and calculus is the gold standard for nonsurgical periodontal treatment. However, complete debridement is difficult, especially in some complex anatomical sites. Excessive scaling may result in the loss of healthy cementum and lead to dental hypersensitivity. Studies have shown that a diode laser can exhibit the best performance in an environment with blood because its wavelengths (630-1 064 nm) are close to the absorption peaks of heme and melanin and they have broad application prospects in the oral field. In nonsurgical periodontal treatment, diode lasers have three treatment modes: soft diode laser, antimicrobial photodynamic therapy and low-level laser therapy, which can be used alone or in combination. Although diode lasers cannot replace mechanical treatment to remove calculus, they can remove infected periodontal pocket epithelium, change the microcirculation to promote wound healing, reduce bleeding and relieve pain through photothermal effects and biological stimulation. The effect of diode laser treatment depends on the treatment dose. It is necessary to precisely control the output intensity and control the irradiation time to avoid thermal damage to the tissue. In the future, extensive research at the molecular level is needed to reveal the tissue response. At the same time, more high-quality, large-sample randomized controlled trials are needed to standardize the use of lasers for different stages and grades of periodontitis.

Types and treatment of peri-implantitis bone defects / 口腔疾病防治

@#The reconstruction effect of peri-implantitis bone defects depends on their morphological characteristics. This paper reviews the morphological classification and treatment of peri-implantitis bone defects. A literature review shows that the morphological classification of bone defects in peri-implantitis includes morphology classification and clinical classification. At present, the Renvert classification is more commonly used in the clinic and is divided into four-wall bone pockets, three-wall bone pockets, two-wall bone pockets, one-wall bone pocket and dehiscence according to the number of bone walls. This has guiding significance in the treatment plan of peri-implantitis. The treatment of peri-implantitis depends on the severity of peri-implant bone defects. Peri-implantitis with mild bone defects is treated by nonsurgical treatment, peri-implantitis with severe bone defects is recommended to remove the implant, and peri-implantitis with moderate bone defects is further judged according to the shape of the bone defects. Four-wall bone pockets, three-wall bone pockets and dehiscence are mostly treated by bone regenerative surgery. For shallow two-wall bone pockets, one-wall bone pockets and horizontal bone resorption, bone resection is often used. However, most peri-implantitis has a variety of bone defect forms at the same time, which need to be treated with bone regenerative surgery and bone resection surgery.

Efficacy of noninvasive correction on congenital auricle deformities at different time points: a meta analysis / 中华医学美学美容杂志

Objective:To evaluate the efficacy and safety of nonsurgical methods in early postnatal correction of congenital auricle malformation.Methods:The clinical trials regarding non-surgical treatment for congenital ear deformity published before May 2021 were searched in databases of Cochrane Library, PubMed, Medline, CNKI, VIP and Wanfang. The information of included studies was extracted. The Meta-analysis was performed by using RevMan 5.3 software.Results:A total of 15 trials were included, involving 1 349 patients. The Meta-analysis results showed that the effect of the group <6 weeks was better than the group over 6 weeks ( OR=4.67, 95% CI: 3.21, 6.78, Z=8.09, P<0.001); The complications incidence of the group < 6 weeks was lower than the group over 6 weeks ( OR=0.27, 95% CI: 0.08, 0.88, Z=2.18, P=0.03); The correction time required of the group <6 weeks was shorter than the group over 6 weeks ( MD=-11.81, 95% CI: -18.36, -5.26, Z=3.54, P=0.001). Conclusions:Non-surgical correction of congenital ear malformation within 6 weeks after birth has better efficacy and safety.

Peri-implantitis and Practical Management: A Review

ABSTRACT@#At present, with an increasing number of implants placed, peri-implant diseases are also increasing. The inclusion of peri-implant disease in the latest classification of periodontal disease shows the global significance of the disease in addition to periodontal disease. Management for peri-implantitis is more complicated and similar to periodontitis, and bone loss is irreversible. Numerous studies throughout the decades were conducted using various techniques investigating the best method in treating peri-implantitis. Therefore, this article will explore the latest evidence for peri-implantitis and its management.

Uso de probióticos como adición al tratamiento periodontal no quirúrgico en pacientes con periodontitis / Use of probiotics as an adjunctive therapy to non-surgical periodontal treatment in patients with periodontitis

RESUMEN Introducción: El tratamiento periodontal no quirúrgico corresponde a la terapia estándar para la periodontitis crónica. En este contexto, se ha propuesto que el uso de probióticos orales como complemento al tratamiento estándar podría mejorar los resultados obtenidos clínicamente, sin embargo no existe claridad respecto a su efectividad. Métodos: Se realizó una búsqueda en Epistemonikos: base de datos de revisiones sistemáticas en salud mantenida mediante el cribado de múltiples fuentes de información, la cuál incluye MEDLINE, EMBASE, Cochrane, entre otras. Se extrajeron los datos desde las revisiones identificadas y un análisis de los datos de los estudios primarios. Se realizó un metanálisis y se preparó una tabla de resumen de los resultados utilizando el método GRADE. Resultados y conclusiones: Se Identificaron seis revisiones sistemáticas que en conjunto incluyeron 14 estudios primarios, todos correspondientes a ensayos aleatorizados. De los resultados analizados se concluye que el uso de probióticos orales como complemento al tratamiento no quirúrgico de periodontitis crónica probablemente resulta en nula o poca diferencia en la reducción de la profundidad de sondaje, el sangrado al sondaje y una ganancia de nivel de inserción clínico en los sitios afectados. Por otro lado, no se encontraron estudios que evaluaran el riesgo de presentar halitosis en pacientes sometidos a terapia periodontal no quirúrgica con adición de probióticos.

ABSTRACT: Introduction: Non-surgical periodontal treatment is the standard treatment to chronic periodontitis. It has been proposed that the use of oral probiotics as an adjunctive therapy may improve clinical outcomes, however there is no clarity regarding its effectiveness. Methods: We searched in Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. Results and conclusions: We identified six systematic reviews including 14 studies overall, of which all were randomized trials. We concluded that the addition of probiotics to non-surgical periodontal treatment probably results in little or no difference in probing depth reduction, clinical attachment level gain and reduction in bleeding on probing. No studies were found evaluating halitosis in patients undergoing non-surgical periodontal treatment with the addition of probiotics.

Treatment plan and clinical effect of the first primary spontaneous pneumothorax in young patients / 中国胸心血管外科临床杂志

@#Objective    To investigate the optimal treatment scheme for the first primary spontaneous pneumothorax (PSP) in young patients. Methods    The clinical data of 171 patients with the first PSP were retrospectively analyzed who were treated in Huaihe Hospital of Henan University between November 2011 and October 2017. There were 157 males and 14 females with a median age of 18 years at onset and a median body mass index of 18.51 kg/m2. According to the treatment methods, they were classified into two groups, a conservative treatment group (a non-surgical group, n=86) and a surgical group (n=85). The characteristics including clinical data, efficacy evaluation criteria, complications and recurrence of the two groups were analyzed. Results    As a result, 73.68% of the patients suffered PSP in their daily routine. The drainage duration in the non-surgical group was longer than that in the surgical group (4 d vs. 3 d, P=0.008). There was no statistical difference in the success rate of lung re-expansion between the two groups (98.85% vs. 100.00%, P=1.000). The proportion of the surgical group using postoperative analgesic drugs was higher than that in the non-surgical group (48.23% vs. 10.46%, P=0.000). The recurrence rate of the surgical group was lower than that of the non-surgical group (3.53% vs. 46.51%, P=0.000). No relationship between smoking and recurrence of pneumothorax was found in both groups (P=0.301, P=1.000). The success rate of lung re-expansion in the non-surgical group was not statistically different between the 24F subgroup and the 12F subgroup (39/39 vs. 33/34, P=0.458). No advantage of intraoperative pleural fixation was found in the surgical group (P=0.693). Conclusion    Thoracoscopic surgery is the first choice for the treatment of the first PSP in young patients.

Epidemiology and Factors Affecting Functional Outcome of Distal Radial Fracture in an Urban Tertiary Medical Centre in Malaysia

@#Introduction: Distal radial fracture is a commonly encountered fracture. This study aims to study the epidemiology of distal radial fracture and factors affecting the patients’ functional outcome one to two years after the injury. Materials and methods: This is a retrospective cohort study. The records of patients, fulfilling the radiographical diagnosis of distal radial fracture, and aged 18 and above, who presented to our Emergency Department from 1st January 2018 to 31st December 2018 were retrieved. According to AO classification, we grouped our patients into A (extra-articular), B (partial articular) and C (complete articular). Patients with congenital abnormalities were excluded. Epidemiological data and relevant medical history were obtained and tabulated. A Malaysian language translation of Disability of the Arm, Shoulder and Hand (DASH) questionnaire was used to assess the functional outcome. Results: Out of 168 patients’ data retrieved, only 110 patients’ data were found complete for purposes of this study. The mean DASH score was 13.7 ± 7.87 approximately one to two years post-injury regardless of treatment method. Increasing age was associated with higher DASH score with r=0.407(p<0.001). Several variables had significantly better functional outcome: male gender (p=0.01), Type A fracture configuration (p=0.007) and non-operational treatment (p=0.03). There was no significant difference between treatment modalities in Type A fracture (p=0.094), but Type B (p=0.043) and Type C (p=0.007) had better outcome without surgery. There was no significant difference between different ethnic groups, open or closed fracture and mechanism of injury. Conclusion: Better functional outcome after sustaining distal radial fracture was associated with young age, male gender, type A fracture and treated non-operatively. Interestingly, more complex fracture pattern had better functionality were observed without surgery.

Comprehensive Review on Non-Surgical Periodontal Therapy

Periodontitis is one the most common diseases of the oral cavity and affects majority of the population. In the recent times there have been several advances in the treatment modalities for the same. One of the most common aetiological factors for the disease is dental plaque. Thus, the aim of various therapeutic options is the elimination of dental plaque. The methods range from something as simple as tooth brushing and oral hygiene practices to those administered by a dental professional. There are various mechanical methods and chemical methods for the same. There are also certain methods like the usage of local drug delivery and mouthwashes that can be used as adjuncts to any type of periodontal therapy. The treatment modalities can be surgical or non-surgical. With the patient being kept at the centre of the equation, non-surgical periodontal therapy is more acceptable to the patient and is also easy to perform and not very complex. In the present review, various options for the management of periodontal disease through non-surgical periodontal therapy have been addressed along with recent advances towards the same.

Treatment of adult patient with hyperdivergent retrognathic phenotype and anterior open bite: report of a case with non-surgical orthodontic approach

ABSTRACT Adult patients with anterior open bite and hyperdivergent retrognathic phenotype demand complex treatments, as premolar extractions, molar intrusion or orthognathic surgery. In the present clinical case, a young adult patient without significant growth, with Class I and anterior open bite, was treated with four premolar extractions. The therapeutic result shows good intercuspation, good facial esthetic, good function balance, and stability in a two-year post-fixed treatment follow-up.

RESUMO Pacientes adultos com mordida aberta anterior e fenótipo hiperdivergente retrognata demandam tratamentos complexos, com extrações de pré-molares, intrusão de molares ou cirurgia ortognática. No presente caso clínico, uma jovem adulta sem potencial significativo de crescimento, apresentando Classe I e mordida aberta anterior, foi tratada com extrações de quatro primeiros pré-molares. O resultado terapêutico alcançou boa intercuspidação, boa estética facial e bom equilíbrio funcional, e mostrou-se estável depois de dois anos da remoção do aparelho fixo.

There were 53 males and 22 females, aged from 18 to 58 (35.62±9.96) years old. The course of disease was from 5 days to 6 months, with an average of (46.45±40.66) days. The lesions were located at L in 4 cases, at L in 29 cases, at LS in 42 cases. Radiation pain in 46 cases on the left and 29 cases on the right. The JOA score, straight leg raising test angle and finger-to-ground distance were assessed pretreatment and at 3 months, 6 months, 1 year, 2 years and 5 years after treatment. The improvement rate of JOA at the final follow up (5 years after treatment) was calculated and the curative effect according to JOA score was evaluated;the volume change of protrusion before treatment and at the final follow-up (5 years after treatment) was analyzed, the volume absorption rate of protrusion was calculated and the absorption of protrusion was observed;the relationship between the improvement rate of JOA and the absorption rate of protrusion were analyzed.@*RESULTS@#Seventy one patients were finally followed up at 5 years after non surgical treatment. The JOA score, straight leg raising test angle and finger to ground distance at 3 months, 6 months, 1 year, 2 years and 5 years after treatment were significantly improved (0.05). There was significant differencein other time points (<0.05). The results of the straight leg raising test angle and the finger-to-ground distance were similar to the JOA scores. The improvement rate of JOA score was (62.69± 2.47)% at the final follow-up. According to JOA score, the results were excellent in 26 cases, good in 26 cases, fair in 14 cases, poor in 5 cases, and the excellent and good rate was 73.24%. The volume of protrusion decreased from (1 981.73±588.72) mm to (1 011.82±395.47) mm3, the total absorption rate was (45.65±2.83)%, the protrusion was obviously absorbed in 24 cases, partially absorbed in 26 cases, not absorbed in 19 cases, and increased in 2 cases. It was found that there was a positive correlation between improvement rate of JOA scores and protrusion absorption rate at 5 years after non surgical treatment (r= 0.679, <0.001).@*CONCLUSION@#Non-surgical treatment of ruptured lumbar disc herniation can achieve good results, clear the characteristics of the ruptured lumbar disc herniation and prognosis, and some patients have "reabsorption" phenomenon.

Efficacy of clarithromycin in the adjuvant treatment of chronic periodontitis: a Meta-analysis / 华西口腔医学杂志

OBJECTIVE@#To evaluate the clinical efficacy of clarithromycin (CLM) in the adjuvant treatment of chronic periodontitis systematically, obtain reasonable conclusions through evidence-based medicine, and provide guidance for clinical rational drug use.@*METHODS@#Literature about CLM in the adjuvant treatment of chronic periodontitis was searched in CNKI, VIP, Wanfang, Chinese Biomedical Literature Database, PubMed, ScienceDirect, and Embase databases from inception to February 2019 using a computer. Meta-analysis was performed on the homogeneous study using RevMan 5.3 software after two independent reviewers screened the literature, evaluated the quality of the study, extracted the data, and evaluated the risk of bias in the included studies.@*RESULTS@#Six randomized controlled trials were included in 316 subjects. The meta-analysis showed that compared with the scaling and root planning (SRP) group, the probing depth (PD) was reduced in patients with CLM and SRP [MD=-1.00, 95%CI (-1.55, -0.45), P=0.000 04]. Clinical attachment loss was obtained [MD=-0.03, 95%CI (0.43, 0.65), P<0.000 01], and the difference between the groups was statistically significant. The modified sulcus bleeding index (mSBI) was reduced [MD=-0.01, 95%CI (-0.14, 0.19), P=0.66]. No significant difference was observed between the groups, but the decrease in mSBI was more significant in CLM combined with SRP group.@*CONCLUSIONS@#CLM combined with subgingival SRP can achieve remarkable results in treating chronic periodontitist.

GNA11 gene rs11084997 polymorphisms might be associated with risk of adult-onset non-surgical hypoparathyroidism / 中华内科杂志

Objective@#To investigate the association of GNA11 gene polymorphisms with the risk of adult-onset non-surgical hypoparathyroidism (Ns-HypoPT).@*Methods@#Genotyping of GNA11 single nucleotide polymorphisms (SNPs) (rs28685098, rs4806907, rs11084997 and rs78003011) was carried out in 203 patients and 209 healthy participants by sequenom MassArray iPLEX System. These SNPs are located in promoter and 3′untranslated region (3′UTR) of GNA11 gene, respectively.@*Results@#Allele and genotype frequencies of rs11084997 in patients were significantly different from those of controls (genotype GG:60.5% vs. 49.8%, GC: 35.5% vs. 41.6%, CC: 4.0% vs. 8.6%, P=0.038; G allele 78.3% vs. 70.6%, C allele 21.7% vs. 29.4%, P=0.012), and the C allele of rs11084997 carriers had a lower risk to develops Ns-HypoPT in additive and dominant genetic models [OR=0.382 (0.160-0.915), 0.647 (0.437-0.957)]. CC-Haplotype formed by the minor alleles of rs4806907 and rs11084997 was associated with a decreased risk of Ns-HypoPT in additive, dominant and recessive genetic model [OR=0.317 (0.126-0.801), 0.640 (0.430-0.952), 0.367 (0.148-0.912)].@*Conclusion@#The minor allele C of rs11084997 in GNA11 gene promoter was associated with decreased risk of Ns-HypoPT in Chinese population.
