Objective: Comparison between semi-ablative and non-ablative radiofrequency for collagen stimulation. Method: Three volunteers with scheduled surgical procedures of abdominoplasty were selected. After the evaluation, the abdominal area was divided into three quadrants, with the right region receiving monopolar non-ablative radiofrequency (RF) application. In contrast, the left region received fractionated radiofrequency (FRF) application, using three different needle sizes (0.5, 1.5, and 3.0 mm), and the intermediate area was kept as a control. After 24 hours, surgery was performed, and the skin flaps were collected for histological and immunohistochemical analyses. Results: An increase in total collagen and type I collagen was observed in the treated groups. There was also an increase in the expression of COX-2, CD68 positive cells (macrophages), and lymphocyte markers (CD3, CD20, and NK-CD57). Furthermore, it was seen that only the use of 3.0-mm needles kept the channels open in the superficial tissue after 24 hours. There were no significant differences between the modalities. Conclusion: Non-ablative and sub-ablative radiofrequency have positive and effective results for flaccidity, demonstrating the success in collagen production. Furthermore, this study is the first to present channel opening and permanence time, which are important to optimize the action of drug delivery.

Cryofrequence is the combination of cryotherapy with radiofrequency, which promotes a “thermal shock” to the tissue, working simultaneously to skin flaccidity and localized adiposity. The efficacy of dermatological and hypodermic cryofrequency treatment was evaluated. This study reports the case of a 45-year-old woman with complaints of flaccidity and fat located in the infra-umbilical region in the preoperative period of abdominoplasty. The evaluation was performed before and after treatment through evaluation protocols, ultrasound examinations and histological findings through optic microscopy, microfocal and immunohistochemical analysis. The treatment was performed in 4 sessions, with a weekly application, using the BHS 156 FULL®—BODY HEALTH BRASIL®apparatus, the parameters were temperature of -10°C, power in 70%, duration of 8 minutes. After the surgical procedure, parts of treated and untreated abdominal tissues were removed for evaluation. In the tests performed, significant destruction of adipocytes was detected, with consequent reduction of fat and greater expression of caspase-3 in the treated tissue, being constated the macrophage increase by CD68 expression. There was improvement in flaccidity, evidenced by the significant increase in the number of fibroblasts and inflammatory cells positive for Ki67, bringing more quantity and better quality to the collagen.

Introduction: Cryofrequency is a novel therapy which was developed with the combination of cold (cryotherapy) and heat (radiofrequency) application, causing a thermal shock effect on skin tissue. The thermal shock is believed to alter local metabolism. Objective: To investigate the effect of cryofrequency on the skin tissue of a mini pig in an in vitro and in vivo experimental model. Methodology: A small swine of the S. domesticus species, a male mini-pig (30 kg weight) was elected for the in vivo procedure subject. The in vitro step was performed on the extracted abdominal part of another subject of the same species and breed. Then, after the application of cryofrequency in the monopolar and bipolar form in vivo, a histological analysis was performed. Results: A higher temperature variation was observed comparing the pilot study in vitro with respect to the experimental one in vivo. Microscopically, an increase of collagen fibers and blood supply and decreased adipose tissue was observed after cryofrequency application. Conclusion: With the bipolar cryofrequency, no reduction of adipose tissue was observed, but regarding the connective tissue, extensive areas of collagen deposition were observed, as well as a great amount of new-formed collagen fibers.

The combination of therapies may be the promising future for the treatment of esthetic alterations more efficiently and in less time, in order to obtain an excellent result. Our objective was to evaluate the effectiveness of hydrolysed collagen associated with radiofrequency and electrostimulation in the treatment of flaccidity in the abdominal and gluteal regions. The sample consisted of 6 women, evaluated through evaluation protocols, questionnaires, dynamometry, ultrasound exams, and histological analysis. The volunteers were distributed into three subgroups: hydrolysed collagen group (G-1), radiofrequency + hydrolysed collagen group (G-2) and radiofrequency + hydrolysed collagen + electrostimulation group (G-3). The ultrasound analysis of the abdominal muscles showed an increase in muscle thickness in all groups, but not significant (p > 0.05). The histological analysis showed an evident increase in type I collagen in groups G-2 and G-3, with proliferating cells (Ki67+). The results of dynamometry showed significant values in different times (p < 0.05). There was a significant result in the infraumbilical perimetry analysis, when compared between the groups with 30 days (p = 0.03) and with 60 days (p = 0.04). All participants rated the treatment positively. The use of combined therapies has shown superior results for the treatment of abdominal and gluteal flaccidity when compared with its isolated use, being the combination of therapies important in the treatment of flaccidity.

Lymphomas are neoplastic transformations that affect lymphoid cells. Diffuse large B-cell non-Hodgkin’s lymphoma has a high degree of cell proliferation, accounting for 30% of all lymphomas. Lung cancer is the leading cause of death worldwide and the recommended treatment is chemotherapy. Among the main complications resulting from non-Hodgkin’s lymphoma, lung cancer and chemotherapy used in their treatment, we can mention sepsis, acute kidney injury and febrile neutropenia. Febrile neutropenia can occur by suppressing the production of neutrophils. Sepsis, a widespread infection, is the main cause of acute kidney injury, which can also be caused by hydroelectrolytic complications or by nephrotoxicity. This is a report of a smoking patient with metastatic lung cancer who sought care due to progressive dysphagia, cough with chest pain, fever, and lower airways critical obstruction due to mediastinal lymphadenopathy, being diagnosed with diffuse large B-cell non-Hodgkin’s lymphoma. The patient evolved to death because of a significant worsening of the ventilatory pattern of multifactorial cause, mainly due to sepsis, acute kidney injury, and febrile neutropenia. The patient had mostly classic characteristics of her comorbidities, however, the overlapping of interrelated comorbidities led to the outcome of death. What is unusual about the present case report is that the patient’s characteristics, such as age, sex, and ethnicity, are opposite to those described as risk factors for diffuse large B-cell non-Hodgkin’s lymphoma.

Patients with decompensated hepatic cirrhosis may present systemic alterations and dysfunction of multiple organs. Ascites, portal hypertension, esophageal varices, and hepatic encephalopathy are common complications arising from cirrhosis. The aim of this paper is to report a case of a patient with liver cirrhosis and the complications of a transjugular intrahepatic portosystemic shunt. Male, elderly, and ex-alcoholic, diagnosed with liver cirrhosis, ascites, and esophageal varices. He underwent transjugular intrahepatic portosystemic shunt due to portal hypertension and returned to the hospital after 24 hours with agitation and mental confusion. He had a bowel movement stop, neurological worsening, loss of renal function, hepatic hydrothorax, hepatic encephalopathy, hypernatremia, hypocalcemia, and hypophosphatemia. He underwent a new procedure to occlude the transjugular intrahepatic portosystemic shunt, showing improvement of the mental status and ascites. However, continued with decompensation and hydro-electrolytic disorders. He evolved with worsening of the ventilatory pattern, and neurological and renal function, with a fatal outcome. Esophageal varices due to portal hypertension can be corrected with the transjugular intrahepatic portosystemic shunt. However, complications such as hypernatremia, hepatic hydrothorax, and hepatic encephalopathy may occur. Therefore, there is a need for reintervention to shunt or reduce its caliber. Thus, for patients with advanced age and decompensated cirrhosis, the potential risks and benefits of this procedure should be carefully evaluated due to the risk of complications and death.

During mechanical alloying variables such as the type of mill,milling intensity,milling time,milling at- mosphere and ball-to-powder weight ratio(BPR)affect the morphology and constitution of the product. The effect of milling time,milling atmosphere and BPR on the nature of the product formed in mechanical- ly alloyed pure Ti and blended elemental binary Ti-Al,and ternary Ti-AI-Nb alloy powders was described. Mechanical alloying of pure titanium results,after long milling times,in the formation of an fcc *** the binary alloy,a solid solution of aluminum in titanium,an amorphous phase,and a fcc phase form with increasing milling *** fcc phase,which is probably a result of TiN formation,occurs more rapidly in air or nitrogen than in an inert *** of the B2 phase in the ternary alloys depends both on alloy composition and the milling atmosphere,with 100％ formation in all atmospheres in Ti-25Al-25Nb but not in Ti-24Al-11Nb,and an inert atmosphere favoring *** times required for the formation of the different phases decrease as the BPR increases;but their sequence is *** on this infor- mation,“milling maps”which describe phase formation as a function of the BPR and milling time are con- *** from the milling balls increased as the BPR was increased.
