ABSTRACT Objective To compare the chest tube drainage by the same thoracotomy intercostal space with the traditional approach in patients undergoing muscle-sparing thoracotomy. Methods We evaluated 40 patients aged ≥18 years who underwent elective muscle sparing thoracotomies. Patients were divided into two groups of 20 patients. One group underwent thoracic drainage by the same intercostal space of thoracotomy and the other by traditional chest drainage approach. Results The mean length of hospital stay for the intercostal drainage group in the intensive care unit was 1.5 day (1.0 to 2.0 days) and 2.0 days (25.1 to 3.0 days) for the traditional chest drainage group (p=0.060). The intercostal drainage group had mean length of hospital stay (p=0.527) and drainage (p=0.547) of 4 days, and the traditional chest drainage group and 2 and 5.5 days, respectively. Dipirona and tramadol doses did not differ between groups (p=0.201 and p=0.341). The mean pain scale values on first postoperative was 4.24 in the drainage by the same intercostal group and 3.95 in the traditional chest drainage (p=0.733). In third postoperative day, mean was 3.18 for the first group and 3.11 for the traditional group (p=0.937). In the 15th day after surgery, drainage by the incision was 1.53 and the traditional chest drainage was 2.11 (p=0.440), 30th days after drainage by incision was 0.71 and traditional chest drainage was 0.84 (p=0.787). Complications, for both groups were similar with 30% in proposed drainage and 25% in traditional approach (p=0.723). Conclusion Drainage by the same thoracotomy intercostal space was feasible and results 30 days after surgery were not inferior to those of the traditional chest drainage approach.

Background: Chondrosarcomas are malignant tumors that are most prevalent between the fourth and sixth decades of life. The surgical resection procedure for primary chest wall chondrosarcoma leads to a good outcome, with a lower probability of recurrence and metastasis. Aim: To report a case of chondrosarcoma resection in the chest wall, and report the evolution of the condition after the resection procedure. Method: This was a young female patient, with tumor recurrence and family genetic history, who underwent resection of a chondrosarcoma in the costal arches. The procedure was carried out at Hospital de Caridade São Vicente de Paulo, Jundiaí - SP, Brazil. Case Report: Woman, 23 years old, who started pain in the left hemithorax radiating to the interscapular region associated with paresthesia of the right upper limb. She reported surgeries to remove osteochondromas in the lower limbs. Two years ago, she had noticed a small lesion in the left hemithorax, which showed significant growth over a period of one year. After outpatient follow-up, and due to hemodynamic stability, it was decided to perform surgical resection of the tumor in the costal arches due to the evolution of pain and functional loss of the left upper limb in 2022. The patient was followed up by the specialty outpatient clinic, and the procedure demonstrated sufficient to treat the tumor. Conclusion: It was possible to perform a single-stage approach of extensive tumor resection, associated with the removal of costal arches and subsequent wall reconstruction. The procedure took place with multidisciplinary team planning, and the patient recovered early with maintenance of function. [ABSTRACT FROM AUTHOR]

ABSTRACT Objective To evaluate the difference in transepidermal water loss in patients diagnosed with hyperhidrosis and healthy subjects, in an air-conditioned environment. Methods Twenty patients diagnosed with hyperhidrosis and 20 healthy subjects were subjected to quantitative assessment using a closed-chamber device, in six previously established sites. Results The measurements showed different transepidermal water loss values for healthy subjects and patients with hyperhidrosis, especially in the hands and feet. In the Control Group, the median for the hands was 46.4g/m2/hour (p25: 36.0; p75: 57.6), while in the Hyperhidrosis Group, the median was 123.5g/m2/hour (p25: 54.3; p75: 161.2) – p
