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.

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.

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.

Clinical application of non-surgical treatment under periodontal endoscope in patients with moderate-to-severe periodontitis of multirooted teeth / 吉林大学学报(医学版)

Objective: To observe the curative effect of non-surgical treatment under periodontal endoscope in the patients with moderate-to-severe periodontal pockets of multirooted teeth after scaling and root planning (SRP), and to expound the clinical significance of periodontal endoscope in assisting periodontal non-surgical treatment. Methods: After SRP, there were still more than 127 multirooted teeth with moderate-to-severe periodontal pockets in 24 patients with periodontitis. The above multirooted teeth received non-surgical treatment under periodontal endoscope, the control of periodontal risk factors was evaluated by the periodontal risk assessment (PRA) model; the probing depth (PD), bleeding on probing (BOP), attachment loss (AL), calculus residual rate of the patients after treatment were detected by Florida Probe system; the percentage of furcation defect was detected. Results: After 3 months of periodontal endoscope-assisted periodontal non-surgical treatment, the risk factors of the patients after treatment were reduced and the patients had good prognosis. The PD value and percentage of BOP positive sites of the teeth of the patients after treatment were significantly decreased compared with before treatment (P0. 05). The percentage of teeth with Class I furcation involvement among the multirooted teeth after treatment was significantly lower than before treatment (P 0. 05). Conclusion: The effect of periodontal endoscope-assisted non-surgical treatment for the multirooted teeth with residual moderate-to-sever periodontal pockets after SRP, and it can avoid periodontal operation to some extent.

Advances of optimized neoadjuvant therapy in the treatment of locally advanced rectal cancer / 中华胃肠外科杂志

Neoadjuvant chemoradiotherapy is the current standard of care for locally advanced rectal cancer. However, this modality is facing more and more challenges. The research progress on this issue around the world can be summarized into three aspects. The first is to increase the intensity of treatment to obtain better tumor regression, such as adding a second drug during the neoadjuvant chemoradiotherapy, prolonging the interval and receiving sufficient chemotherapy before surgery. Current research data are not sufficient to support strategies for adding drugs or receiving sufficient chemotherapy before surgery, but it may be worth looking forward to adding irinotecan during neoadjuvant chemoradiotherapy, and an appropriate extension of the interval before surgery may also be a good option. Secondly, we can reduce the intensity of treatment to improve the quality of life of patients with a non-inferior clinical outcome, such as non-surgical approach, local excision rather than total mesorectal excision and removal of preoperative radiotherapy. The data of the International Watch & Wait Database (IWWD) suggest that patients with a Watch & Wait strategy have similar long-term survival outcomes as those who have undergone surgery and have pathologic complete response, meanwhile the data are still inadequate to support using local excision instead of total mesorectal excision, or removal of preoperative radiotherapy strategies. Finally, to achieve a precise individual treatment, some potential biomarkers are investigated via genomics, metabolomics and radiomics. But so far, there is no recognized biomarker for clinical treatment in the field of neoadjuvant therapy for rectal cancer. This article summarizes the clinical research progress of locally advanced rectal cancer in recent years from the above three aspects.

"Research advances in ""treatment resistance"" of non-operative therapies for hepatocellular carcinoma" / 复旦学报（医学版）

Hepatocellular carcinoma (HCC) has the characteristics of high malignancy and poor prognosis.Liver transplantation and hepatectomy are applied in a small portion of patients with localized disease.Due to the hidden onset,HCC is usually diagnosed at an intermediate-advanced stage or with advancing cirrhosis.In most cases,various non-operative treatments are applied,including transarterial chemoembolization (TACE),local ablation,radiotherapy and molecular targeted drugs.The therapeutic effect of non-surgical treatments is not always ideal because the incidence of recurrence and metastasis after treatment is high.It also may be associated with treatment resistance of HCC to non-operative treatments.Optimizing the current management schemes has great significance in improving patients' quality of life and prolonging their survival.

Therapeutic Consideration of Periappendiceal Abscess: an Evaluation of Non-surgical Treatment Followed by Minimally Invasive Interval Appendectomy

PURPOSE: Periappendiceal abscess (PAA) is a severe complicated appendicitis with high morbidity. Non-surgical treatment followed by interval appendectomy (IA) is associated with lower complication rate compared with emergency surgery (ES) and minimally invasive surgery (MIS) can be done more often. The purpose of this study is to assess the incidence and factors predictive of complications of surgery for PAA and to evaluate the clinical effectiveness of IA as a treatment policy to increase MIS. METHODS: Retrospectively, we reviewed 171 patients undergoing surgery for PAA between 2011 and 2016 at Ulsan University Hospital. The incidence and influence of different factors were assessed by univariate and multivariate analyses. RESULTS: In 171 patients, 28 (16.4%) developed postoperative complications, which included; wound complications (7.6%), intra-abdominal abscess (4.1%) and ileus (2.9%). In both analyses, only ES was independently associated with postoperative complications; (Relative risk, 15.0; 95% Confidence interval, 2.4~92.5). Comparing the IA and ES groups revealed that operative time, complication rate, laparoscopic approach, postoperative hospitalization, postoperative antibiotic use and bowel resection rate were significantly different. The postoperative complication rate of patients with PAA in ES group was 28.7%, which was statistically higher than that of IA group (3.6%). Especially, MIS rate was more than 9-times greater in the IA group (98.8% vs. 10.3%, p<0.001). Although the IA group required additional hospitalization, there was no statistical difference between the two groups in total length of hospital stay. CONCLUSION: Morbidity was high for patients who had emergency surgery for PAA. ES was the only factor associated with postoperative morbidity. IA can reduce the postoperative complication rate and allowed MIS to be used more often as a useful treatment policy for PAA.

A comparative study of new clinical staging systems for esophageal carcinoma treated with non-surgical therapy / 中华放射肿瘤学杂志

Objective To evaluate the predictive values of different systems for clinical staging of esophageal carcinoma in one group of patients and improve the criteria for T staging,and to provide a basis for accurate clinical staging. Methods A retrospective study was performed in 701 patients with esophageal carcinoma who received radical radiotherapy in our hospital. The prognosis was performed according to American Joint Committee on Cancer ( AJCC) tumor-node-metastasis staging system,Chinese 2004 staging system,the draft of Chinese 2009 staging system,and gross tumor volume of the primary tumor (GTV-T). Results In terms of T stage,patients evaluated according to the AJCC staging system were in relatively early stages;23. 1% of them were in stage T1,and the survival curves of T3 and T4 patients were close to each other;the survival curves plotted according to the Chinese 2004 staging system were well separated, but relatively few patients were in stages T1 and T4 , yielding an uneven distribution;according to the draft of Chinese 2009 staging system, the survival curve of T3 patients intersected that of T4 patients, and up to 43. 2% of patients were in stage T4.The new T staging was performed based on GTV and the extent of tumor invasion into the adjacent tissue and organ, and the results showed that there was no intersection between survival curves and a relatively balanced T stage distribution. In terms of N staging,patients were divided into stages N0 ,N1 ,and N2 . The TNM staging was performed by a combination of N staging and new T staging, resulting in significant separation between survival curves ( P=0. 000) . Conclusions The combination of T staging,which is based on GTV and the extent of tumor invasion,and N staging,which is based on metastasis of lymph nodes, can accurately predict the survival of non-surgically treated patients with esophageal carcinoma.
