Introduction: Testicular cancer is the most common malignancy in men from 15 to 45 years, it represents 1% of male tumors and 5% of urological malignancies, its incidence has doubled in the last 40 years; effective management and prognosis are excellent with >90% healing rate and >95% survival rate at 5 years. Objective: to explain the clinical- epidemiological characteristics of diffuse testicular lymphoma of large B cells. Methodology: we made a review of the bibliography on the subject and presented the results. Results and discussion: Lymphomas areup to34.7% of paratesticular stromal tumors and may be primarys (LTP) or secondarys. Diffuse large B-cell lymphoma (LDCGB) is the most common type of testicular lymphoma. Most patients have a one-sided testicular mass andup to90% have stage I or II disease at the time of diagnosis. In 35% of patients, bilateral testicular involvement is detected and in more advanced stages there is paraaortic lymph node involvement; ascites and abdominal pain are evident. The surgical treatment combined with R-CHOP21, IT-MTX and RT testicular has been associated with a good result. We made a case presentation of a patient diagnosed with diffuse testicular lymphoma of large B cells. Conclusions: testicular lymphoma can be primary or secondary and its management is based on orchiectomy and chemotherapy.

Introduction: COVID 19 is a pandemic disease caused by the SARS-CoV-2 virus, with several groups vulnerable to complications of infection such as patients with lung cancer, associated with immunosuppression due to the oncospecific treatment imposed. Objective: to determine the effectiveness of an educational intervention on Covid-19 in patients with lung cancer and their families. Methodology: A quasi-experimental, before-after study was carried out through an educational intervention during the period from the first of September 2020 to October 31 of that same year, through an applied survey. The intervention was designed in three stages: diagnostic, intervention itself and evaluative. Results: A significant increase in the level of adequate knowledge was observed after the educational intervention on generalities of Covid-19 (84.8%), signs and symptoms of disease (95.7%), complications (82.6%), prevention measures (100%) and susceptibility to Covid-19 (93.5%). Discussion: the educational intervention allows to increase the perception of the risk in those who receive it, guaranteeing a better act in them. Conclusions: the educational intervention increased knowledge about Covid-19 and its effectiveness was demonstrated.

Introduction: Breast cancer is a group of tumors that can show similar clinical and homogeneous histological aspects, however, with a very diverse biological behavior and a great variability in the response to treatment. The current histological classification based on hematoxylin eosin does not allow to identify the patients who will present better responses and benefits with the different therapeutic modalities. Immunohistochemistry is related to the chemical activity of cells and tissues. Objective: To explain the importance of immunohistochemistry in therapeutic selection in breast cancer. Methodology: We consulted the literature related to the topic and carried out this review. Results and discussion: Taking into account the advances obtained with the immunohistochemistry technique, it is possible to have a more accurate prediction of behavior, allow a personalized therapy with better control of the disease, relapse-free survival and overall survival. Conclusions: The development of immunohistochemistry allows personalized therapies according to subtypes in breast cancer, achieving significant benefits in disease control and survival.

Background: The attention of patient with epicodyliti affect the quality of life that the people inflicted inability and labor absence, for all this constitute a health problem. Objective: Demonstrate the effectiveness of the Laser and Magnetic camp in Epicondylitis treatment, carried out in the Integral Service of Rehabilitation in Amarillas, municipality Calimete, Matanzas province, during September 2018 to September 2019. Material and method: It was an experimental, explicative study over de patients clinically diagnosed of Epicondilytis referred from Roman Sanchez`s clinic with acute or chronic evolution, over 20 years old. The sample was 54 patients formed for two groups, a target group composed by 27 patients, which received the combination treatment (Laser and Magnetic camp), the control group(27patients) received a conventional treatment with an analgesic (Dipirone) and an antiflammatory (Ibuprofen 400mg) twice per day for 10 day. The magnetic camp was applied around the elbow joint affected; in addition, the laser was applied in acupuncture points for10 sections. Both groups was applied a qualitative score  ( Liked) to evaluate the pain intensity and functional capacity to do daily activities( Wadell test modified), to statistic    process  was used “ The  prove of signs” and “The Mann Whitney prove” considered significant  value of P<0,05. Results: The study show that Epicodylitis predominated in male, between 40 to 49 years old which are doing labor field. In 85, 2 %( 23 patient) the pain disappeared. Conclusion: The combination between Laser and Magnetic treatment were useful to improve or alleviate the pain of this illness and help to improve or recuperate the functional capacity of the arm affected.

We define violence as aggressive behavior, the intention of which is to cause harm to the person who exercises it, starting from this brief concept we can cite that intrafamily violence is the type of aggressive behavior that occurs between members of a family, or also the case of people related either by consanguinity or by affinity. The present case is about a female, adult, victim of verbal aggression by her sentimental partner, with the final result of the aggression being extensive physical injuries. As a conclusion we have a case of domestic violence whose perpetrator was the sentimental partner of the patient, although the injuries were not directly provided by the aggressor, but the death threats were those that triggered the survival reaction in the victim and indirectly caused extensive physical injuries.
