- Opções de tratamento cirúrgico em lesões cutâneas por extravasamento acidental de drogas: experiência do Hospital das Clínicas da Faculdade de Medicina da USP.(2018) MILCHESKI, Dimas André; MOTA, Wellington Menezes; LOBATO, Rodolfo Costa; MONTEIRO JÚNIOR, Araldo Ayres; GEMPERLI, RolfABSTRACT Objective: to report the experience of the Division of Plastic Surgery of the Hospital das Clínicas of the Medical School of the University of São Paulo in the treatment of cutaneous lesions due to accidental extravasation of drugs. Methods: we included patients with lesions due to extravasation of drugs over a period of 18 months. We retrospectively evaluated the following parameters: age, diagnoses during hospitalization and comorbidities, serum levels of albumin and hemoglobin, place of hospitalization, drug involved, anatomic segment affected, therapeutic management and death during hospitalization. Results: we followed-up 14 patients. The main drug involved was noradrenaline (21%). All patients underwent debridement of tissue necrosis. Three patients were submitted to flaps after preparation of the wound bed with negative pressure therapy, with good results. Seven patients had no definitive treatment of their lesions due to lack of clinical conditions. Conclusion: in patients with favorable clinical conditions, the definitive treatment with flaps was adequate for cases of wounds due to extravasation of drugs in the subcutaneous tissue when there was exposure of noble structures.
- Sensory Testing in Patients With Hemodialysis-Associated Carpal Tunnel Syndrome Submitted to Surgical Decompression(2014) NAKAMOTO, Hugo Alberto; FERREIRA, Marcus Castro; TUSTUMI, Francisco; MILCHESKI, Dimas A.; TUMA, PauloBackground: Carpal tunnel syndrome (CTS) is the most common compression neuropathy of the upper limb. Close to 5% of patients with chronic renal failure who need hemodialysis present CTS. Clinical history and physical examination remain the most adequate tools for diagnosis, and there is still controversy regarding the most reliable test to complement it. Evaluation of sensory thresholds using Pressure-Specified Sensory Device (PSSD) has become an important instrumental test. Method: This study aimed to determine the values of pressure sensory thresholds using the PSSD before and after treatment of CTS in a special group of patients who underwent chronic hemodialysis. The PSSD incorporates a pressure transducer linked to a computer capable of measuring the cutaneous pressure thresholds referred by the patient. Two groups were compared as follows: group 1, patients with hemodialysis-related CTS; and group 2, CTS in nonYhemodialysis patients. The following measurements were assessed: static one point, moving one point, static two points, and moving two points. Results: There was improvement (lower thresholds) in the postoperative measurements in all parameters assessed in group 1, and improvements in all parameters except the moving one point test in group 2. Conclusions: Nerve decompression, as expected, can be considered a good treatment of CTS even in more severe cases as in those patients under hemodialysis. The PSSD tests were reliable to confirm the diagnosis and thus to indicate the decompression. It is even more beneficial to provide a comparison between preoperative and postoperative data and different causes of CTS.
- Terapia por pressão negativa na ferida traumática complexa do períneo(2013) MILCHESKI, Dimas André; ZAMPIERI, Felipe Muniz de Castro; NAKAMOTO, Hugo Alberto; TUMA JÚNIOR, Paulo; FERREIRA, Marcus CastroOBJECTIVE: To review the experience (2011 and 2012) of Wound Center of Plastic Surgery Service, Clinics Hospital, Faculty of Medicine, University of São Paulo, with treatment of complex traumatic wounds in the perineal region with the association of negative pressure wound therapy followed by a surgical skin coverage procedure. METHODS: This was retrospective analysis of ten patients with complex wound in the perineum resulting from trauma assisted by the Department of Plastic Surgery in HC-USP. Negative pressure was used as an alternative for improving local conditions, seeking definitive treatment with skin grafts or flaps. RESULTS: Negative pressure was used to prepare the wound bed. In patients, the mean time of use of negative pressure system was 25.9 days, with dressing changes every 4.6 days. After negative pressure therapy, 11 local flaps were performed in nine patients, with fasciocutaneous anterolateral thigh flap used in four of these. Mean hospital stay was 58.2 days and accompaniment in Plastic Surgery was 40.5 days. CONCLUSION: The use of negative pressure therapy led to improvement of local wound conditions faster than traditional dressings, without significant complications, proving to be the current best alternative as an adjunct for the treatment of this type of injury, always followed by surgical reconstruction with grafts and flaps.

- Uso da terapia por pressão subatmosférica em feridas traumáticas agudas(2013) MILCHESKI, Dimas André; FERREIRA, Marcus Castro; NAKAMOTO, Hugo Alberto; PEREIRA, Diego Daniel; BATISTA, Bernardo Nogueira; TUMA JR, PauloOBJECTIVE: To evaluate the use of subatmospheric pressure therapy in the treatment of acute traumatic injuries of the soft tissues, especially in the limbs. METHODS: One hundred and seventy-eight patients with traumatic wounds were treated by the Center for Complex Wounds in the period from January 2010 to December 2011, and submitted to subatmospheric pressure therapy (SPT). RESULTS: Of the 178 patients who underwent SPT, 129 (72.5%) were male and 49 (27.5%) were aged between 18 and 40 years. Degloving injuries to the limbs were the most common type of traumatic wounds, being responsible for the hospitalization of 83 (46.6%) patients. Mean hospital stay was 17.5 days. A total of 509 procedures were performed (average 2.9 per patient). SPT was used in 287procedures, 209 (72.8%) on traumatic wounds and 78 (27.2%) of skin grafts. The number of exchanges of the SPT apparel per patient was 1.6 and the mean time of use, 8.5 days. CONCLUSION: SPT significantly reduced morbidity and healing time of injuries when compared with previously performed dressing treatments. The subatmospheric pressure therapy is a useful method in treating acute traumatic wounds, acting as a bridge between the emergency treatment and the final coverage of the skin lesions, being better when compared with more traditional methods of plastic surgery.
- Experimental Model of Degloving Injury in Rats Effect of Allopurinol and Pentoxifylline in Improving Viability of Avulsed Flaps(2013) MILCHESKI, Dimas A.; NAKAMOTO, Hugo A.; TUMA JR., Paulo; NOBREGA, Lucas; FERREIRA, Marcus C.Background: Degloving injuries may be a challenge when it comes to deciding the surgical approach to be used. Repositioning of the flap and suturing are faster and more straightforward, but often these procedures often lead to total or partial loss of the avulsed flap. Pharmacological agents with vascular properties that enhance the viability of the reattached flap could be beneficial to patients with degloving injuries. Experimental models with which to test this hypothesis are scarce. An experimental model reproducing a degloving injury of the hind limb of rats was developed in our department, and the effects of pentoxifylline (Ptx) and allopurinol (Alp) were assessed. Methods: In all, 3 groups of rats were studied (25 rats each). A hind limb degloving model was used in all groups, resulting in a reverse flow flap. The flap was then repositioned and sutured. The control (Ct) group received only saline solution, the Ptx group received pentoxifylline (25 mg/kg), and the Alp group received allopurinol (45 mg/kg). The rats were observed for 7 days, after which they were killed, and the flap was removed. The total area of the avulsed flap and the necrotic area were measured. Results: The median total flap area (cm(2)) was 5.6 for the Ct group, 5.5 for the Ptx group, and 5.8 for the Alp group (P = 0.9465). Thus, the flaps were similar. The median necrotic flap area (cm(2)) was 3.3 for the Ct group, 2.3 for the Ptx group, and 1.9 for the Alp group (P = 0.0001). There was a statistical difference between the Ct and Ptx groups and the Ct and Alp groups (P < 0.05). Conclusions: The areas of necrosis observed in the degloved flaps of the rats' hind limbs were smaller in the pentoxifylline and allopurinol groups. Although allopurinol seems to be more efficient, the difference was not significant.
- Brief hospitalization protocol for pressure ulcer surgical treatment: outpatient care and one-stage reconstruction(2017) MILCHESKI, Dimas André; MENDES, Rogério Rafael da Silva; FREITAS, Fernando Ramos de; ZANINETTI, Guilherme; MONEIRO JÚNIOR, Araldo Ayres; GEMPERLI, RolfABSTRACT Objective: to evaluate a brief hospitalization protocol for the treatment of pressure ulcers, proposed by the Complex Wound Group of Clinical Hospital of University of Sao Paulo Medical School, particularly in regard to selection of patients, hospitalization time, cutaneous covering, complications and sore recurrence. Methods: retrospective cohort of 20 consecutive patients with 25 pressure lesions Grade IV. All patients were ambulatorily prepared and were hospitalized for surgical one time procedure for pressure lesion closing. Results: in total, 27 flaps were performed to close 25 wounds. Three patients showed minor dehiscence (11.1%). There was no recurrence during the post-surgical follow-up period. No patient suffered a new surgery and no flap showed partial or total necrosis. Median time of hospitalization was 3.6 days (2-6 days) and median follow-up was 91 months (2-28 months). All patients maintained their lesions closed, and there was no recurrence during follow-up. Conclusion: the brief hospitalization protocol was considered adequate for the resolution of pressure wounds, showing an average time of hospitalization of 3.6 days and rate of minor surgical wound dehiscence of 11.1%.
- Experiência inicial com terapia por pressão negativa por instilação em feridas complexas(2017) MILCHESKI, Dimas André; PORTOCARRERO, Marcelo Lima; ALVAREZ, Daniel Mamere; MAZUCA, Luiz Guilherme de Moraes Prado; MONTEIRO JUNIOR, Araldo Ayres; GEMPERLI, RolfABSTRACT Objective: to report the initial experience with Negative-Pressure Wound Therapy with instillation in infected or contaminated complex wounds. Methods: the negative-pressure wound therapy with instillation used was V.A.C. Ulta with Veraflo instillation (Kinetic Concepts, Inc). The mode of operation was continuous with negative pressure set at 125 mmHg for two hours and instillation between the pauses. The instillation time was 20 minutes (contact time of the topical agent with the wound) and the instilled substance was 0.9% normal saline. After adequate preparation of the wound, it was covered with graft or flap. Results: ten patients with complex or contaminated wounds were operated on. The mean number of NPWTi changes was 1.4, the mean number of surgeries was 2.4, the interval until complete wound coverage was 6.3 days, and the interval up to the time of discharge was 11.4 days. Conclusion: the comparison of the negative-pressure wound therapy with instillation with two previous studies (historical control) evidenced a shorter hospitalization time, favoring TPNi. This study had an initial character, making it necessary to conduct a randomized and controlled trial to confirm the efficacy of this therapy and verify its cost-effectiveness.
