- Bactec (TM) blood culture bottles allied to MALDI-TOF mass spectrometry: rapid etiologic diagnosis of bacterial endophthalmitis(2017) TANAKA, Tatiana; OLIVEIRA, Luiza Manhezi de Freitas; FERREIRA, Bruno Fortaleza de Aquino; KATO, Juliana Mika; ROSSI, Flavia; CORREA, Karoline de Lemes Giuntini; PIMENTEL, Sergio Luis Gianotti; YAMAMOTO, Joyce Hisae; ALMEIDA JUNIOR, Joao NobregaMatrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry (MS) has been used for direct identification of pathogens from blood-inoculated blood culture bottles (BCBs). We showed that MALDI-TOF MS is an useful technique for rapid identification of the causative agents of endophthalmitis from vitreous humor-inoculated BCBs with a simple protocol.
- Human islet xenotransplantation in rodents: A literature review of experimental model trends(2017) IUAMOTO, Leandro Ryuchi; FRANCO, Andre Silva; SUGUITA, Fabio Yuji; ESSU, Felipe Futema; OLIVEIRA, Lucas Torres; KATO, Juliana Mika; TORSANI, Matheus Belloni; MEYER, Alberto; ANDRAUS, Wellington; CHAIB, Eleazar; D'ALBUQUERQUE, Luiz Augusto CarneiroAmong the innovations for the treatment of type 1 diabetes, islet transplantation is a less invasive method of treatment, although it is still in development. One of the greatest barriers to this technique is the low number of pancreas donors and the low number of pancreases that are available for transplantation. Rodent models have been chosen in most studies of islet rejection and type 1 diabetes prevention to evaluate the quality and function of isolated human islets and to identify alternative solutions to the problem of islet scarcity. The purpose of this study is to conduct a review of islet xenotransplantation experiments from humans to rodents, to organize and analyze the parameters of these experiments, to describe trends in experimental modeling and to assess the viability of this procedure. In this study, we reviewed recently published research regarding islet xenotransplantation from humans to rodents, and we summarized the findings and organized the relevant data. The included studies were recent reports that involved xenotransplantation using human islets in a rodent model. We excluded the studies that related to isotransplantation, autotransplantation and allotransplantation. A total of 34 studies that related to xenotransplantation were selected for review based on their relevance and current data. Advances in the use of different graft sites may overcome autoimmunity and rejection after transplantation, which may solve the problem of the scarcity of islet donors in patients with type 1 diabetes.
- Correlation among ocular surface disease, xerostomia, and nasal symptoms in patients with differentiated thyroid carcinoma subjected to radioiodine therapy: A prospective comparative study(2017) FONSECA, Fabricio Lopes da; YAMANAKA, Patricia Kazue; MAZOTI, Luciana; ARAKAWA-SUGUENO, Lica; KATO, Juliana Mika; MATAYOSHI, SuzanaBackground: Some complications of radioiodine therapy have been reported, but the involvement of the eyes and adnexa is rarely discussed. The purpose of this study was to determine the correlation among ocular surface changes, xerostomia, and changes in the nasal mucosa associated with radioiodine therapy. Methods: Patients subjected to radioiodine therapy (group 1) or not subjected (group 2) were prospectively evaluated by examinations of the ocular surface and tear film, saliva production, and nasal endoscopy. Ocular and nasal symptoms and xerostomia were evaluated using questionnaires. Results: Evaluation of the ocular surface did not indicate significant differences between the groups. Nasal endoscopy revealed higher mucosal pallor in group 1 and worsening of the endoscopic appearance. Worsening of ocular symptoms and nasal symptoms, xerostomia, and a significant decrease in salivary production was also observed in group 1. Conclusion: Subjective worsening of xerostomia, xerophthalmia, nasal symptoms, and changes in the nasal mucosa in group 1 was observed.

Recent studies have identified BMI as an independent factor for technical difficulty in the learning period. Aim: To analyze the effect of overweight and obesity on the technical difficulties of TEP. Method: Prospective study on patients who underwent a symptomatic inguinal hernia by means of the TEP technique. Were analyzed gender, BMI, previous surgery, hernia type, operative time and complications. Technical difficulty was defined by operative time, major complications and recurrence. Patients were classified into four groups: 1) underweight, if less than 18,5 kg/m²; 2) normal range if BMI between 18,5 and 24,9 kg/m²; 3) overweight if BMI between 25-29,9 kg/m²; and 4) obese if BMI≥30 kg/m². Results: The cohort had a total of 190 patients, 185 men and 5 women. BMI values ranged from 16-36 kg/m² (average 26 kg/m²). Average operating time was 55.4 min in bilateral hernia (15-150) and 37.8 min in unilateral (13-150). Time of surgery was statistically correlated with increased BMI in the first 93 patients (p=0.049). Conclusion: High BMI and prolonged operative time are undoubtedly correlated. However, this relationship may be statistically significant only in the learning period. Although several clinical features can influence surgical time, upon reaching an experienced level, surgeons appear to easily handle the challenges.
- Learning curve takes 65 repetitions of totally extraperitoneal laparoscopy on inguinal hernias for reduction of operating time and complications(2017) SUGUITA, Fabio Yuji; ESSU, Felipe Futema; OLIVEIRA, Lucas Torres; IUAMOTO, Leandro Ryuchi; KATO, Juliana Mika; TORSANI, Matheus Beloni; FRANCO, Andre Silva; MEYER, Alberto; ANDRAUS, WellingtonInguinal hernia repair is one of the most frequently conducted surgical procedures worldwide. Totally extraperitoneal (TEP) hernioplasty has shown many advantages over traditional open surgery. However, because of increased surgical complexity, it requires more practice to achieve optimal results. The aim of this study is to evaluate the learning curve for TEP hernioplasty, analysing parameters related to the mean operating time. The secondary objective is to assess the complications and early discharge rates related to this procedure. A prospective study of 238 consecutive patients undergoing TEP hernioplasty from the same practitioner between May 2009 and May 2014, in a specialised centre for abdominal hernias in Sao Paulo, Brazil, was conducted. All data were obtained through medical records. The study included 137 patients undergoing a total of 157 TEP hernia repairs. Bilaterality and complications can influence the operating time and so were excluded. Patients with unilateral surgery and without complications were included. Patients were chronologically divided into four groups. Groups 1-3 were composed of 35 patients and group 4 of 32. There were no significant variations in clinical characteristics between the groups. The plateau of the learning curve was reached on the 65 th repetition of the surgery, with a mean operating time of 28 min (p < 0,05). Complications were only observed in the first group of 35 patients. 97% of patients were discharged early, defined as patient leaving hospital less than 12 h after surgery. After an initial reduction, the mean operating time stabilised after 65 cases. A reduction in the rate of complications was observed after 35 cases, and a rate of 97% of early discharge was achieved.
