conferenceObject Clinical characteristics, outcome, and management of Staphylococcus epidermidis endophthalmitis(2019) TANAKA, Tatiana; KATO, Juliana Mika; OLIVEIRA, Luiza Manhezi Shin de Shin de; ODA, Eduardo Ferracioli; BARBOSA, Thaisa Silveira; ROSSI, Flavia; ALMEIDA JUNIOR, Joao Nobrega; YAMAMOTO, Joyce Hisae- 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.
- Laparoscopic totally extraperitoneal (TEP) hernioplasty using two trocars: anatomical landmarks and surgical technique(2015) IUAMOTO, Leandro Ryuchi; KATO, Juliana Mika; MEYER, Alberto; BLANC, PierreBACKGROUND: Among endoscopic hernioplasties, totally extraperitoneal (TEP) and transabdominal preperitoneal (TAPP) approach are widely accepted alternatives to open surgery, both providing less postoperative pain, hospital length of stay and early return to work. Classical TEP technique requires three skin incisions for placement of three trocars in the midline or in triangulation. AIM: To describe a technique using only two trocars for laparoscopic total extraperitoneal for inguinal hernia repair. METHOD: Extraperitoneal access: place two regular trocars on the midline. The 10 mm is inserted into the subcutaneous in horizontal direction after a transverse infra-umbilical incision and then elevated at 60º angle. The 5 mm trocar is inserted at the same level of the pubis with direct vision. Preperitoneal space dissection: introduction 0º optical laparoscope through the infra-umbilical incision for visualization and preperitoneal dissection; insufflation pressure must be below 12 mmHg. Dissection of some anatomical landmarks: pubic bone, arcuate line and inferior epigastric vessels. Exposure of ""triangle of pain"" and ""triangle of doom"". Insertion through the 10 mm trocar polypropylene mesh of 10x15 cm to cover the hernia sites. Peritoneal sac and the dorsal edge of the mesh are repositioned in order to avoid bending or mesh displacement. It is also important to remember that the drainage is not necessary. RESULTS: The 2-port TEP required less financial costs than usual because it is not necessary an auxiliary surgeon to perform the technique. Trocars, suturing material and wound dressing were spared in comparison to the classical technique. Besides, there were only two incisions, which provides a better plastic result and less postoperative pain. CONCLUSION: The TEP technique using two trocars is an alternative technique which improves cosmetic and financial outcomes.
conferenceObject Explanted Scleral Buckle, a retrospective study(2015) OLIVEIRA, Luiza Manhezi de Freitas; GIOIA, Thais Sabota Romano Di; ROSA, Valeria Teixeira Alves; ALMEIDA, Joao Nobrega de Nobrega de; ROSSI, Flavia; KATO, Juliana Mika; FERREIRA, Bruno Fortaleza de Aquino; TANAKA, Tatiana; NAKASHIMA, Yoshitaka; PIMENTEL, Sergio Luis Gianotti- 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.
- Detection of coronavirus-2 by real-time reverse transcription polymerase chain reaction in conjunctival swabs from patients with severe form of Coronavirus disease 2019 in Sao Paulo, Brazil(2021) MISAWA, Mariana Akemi Matsura; TANAKA, Tatiana; MINELLI, Tomas; BRAGA, Pedro Gomes Oliveira; KATO, Juliana Mika; GOUVEA, Michele Soares Gomes; PINHO, Joao Renato Rebello; YAMAMOTO, Joyce HisaeOBJECTIVES: To test conjunctival swabs from patients with laboratory-confirmed severe forms of coronavirus disease 2019 (COVID-19) for the presence of SARS-CoV-2 on real-time reverse-transcription polymerase chain reaction (rRT-PCR). METHODS: Fifty conjunctival swabs were collected from 50 in-patients with laboratory-confirmed severe forms of COVID-19 at the largest teaching hospital and referral center in Brazil (HCFMUSP, Sao Paulo, SP). The samples were tested for SARS-CoV-2 on rRT-PCR with the primers and probes described in the CDC protocol which amplify the region of the nucleocapsid N gene (2019_nCoV_N1 and 2019_nCoV_N2) of SARS-CoV-2 RNA and compared with naso/oropharyngeal swabs collected within 24 hours of the conjunctival swabs. RESULTS: Five conjunctival samples (10%) tested positive (amplification of the N1 and N2 primer/probe sets) while two conjunctival samples (4%) yielded inconclusive results (amplification of the N1 primer/probe set only). The naso/oropharyngeal swabs were positive for SARS-CoV-2 on rRT-PCR in 34 patients (68%), negative in 14 (28%) and inconclusive in 2 (4%). The 5 patients with positive conjunctival swabs had positive (n=2), negative (n=2) or inconclusive (n=1) naso/oropharyngeal swabs on rRT-PCR. Patients with negative or inconclusive naso/oropharyngeal swabs had the diagnosis of COVID-19 confirmed by previous positive rRT-PCR results or by serology. CONCLUSION: This is the first study to present conjunctival swab rRT-PCR results for SARS-CoV-2 in a Brazilian population. In our sample of 50 patients with severe forms of COVID-19, 10% had positive conjunctival swabs, most of which were correlated with positive naso/oropharyngeal rRT-PCR results.
- 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.
conferenceObject Etiology and susceptibility pattern of isolates in endophthalmitis over a 5-year period(2015) KATO, Juliana Mika; OLIVEIRA, Maura Salaroli de; LEVIN, Anna Sara; ALMEIDA, Joao Nobrega de Nobrega de; ROSSI, Flavia; OLIVEIRA, Luiza Manhezi de Freitas; RUPPERT, Aline Domingos Pinto; TANAKA, Tatiana; NAKASHIMA, Yoshitaka; PIMENTEL, Sergio Luis Gianotti- Visual loss after aesthetic facial filler injection: a literature review on an ophthalmologic issue(2022) KATO, Juliana Mika; MATAYOSHI, SuzanaDermal filler injection is among facial rejuvenation treatments that have been increasingly used. Despite being a minimally invasive procedure, it can lead to severe complications such as blindness. A review of all cases of filler-induced visual loss in the world literature was conducted to summarize the mechanisms, anatomical considerations, and clinical ophthalmologic course, current strategies of prevention and management, and trends over the years. We identified 233 cases of filler-induced visual loss, and 172 patients had a severe visual impairment in at least one eye. The typical patients are young women who received injections of hyaluronic acid or autologous fat in the glabella or nose, and the typical presentations were sudden ocular pain, ptosis, and ophthalmoplegia due to vascular occlusion. The findings of this study also suggest an increase in the number of unlicensed professionals performing the procedure. Even though the continued development of dermal fillers has improved the treatment options available, further studies and strategies are necessary to reduce the incidence and minimize the consequences of filler-induced visual loss.
