BACKGROUND Carcinoid tumor, benign, low-grade malignant, and high-grade malignant, can be associated with the release of vasoactive substances that cause symptoms including cutaneous flushing, diarrhea, and bronchospasm. In 50-60% of patients with carcinoid syndrome, the vasoactive substances cause fibrosis of the pulmonary and tricuspid heart valves which lead to regurgitation and right-sided heart failure. The right side of the heart is usually affected because monoamine oxidases in the lungs usually inactivate the vasoactive substances...

OBJECTIVE: This clinical study describes a reconstructive method for facial soft-tissue defects that uses the pre-expanded forehead flap and minimizes donor site morbidities. METHODS: The surgery was subdivided into 3 stages. First stage, an appropriately sized expander was buried underneath the forehead. Second stage, after adequate inflation of the expander, a forehead flap based on the frontal branches of the superficial temporal artery was raised, and the distal portion of the flap was used to reconstruct the facial defect...

BACKGROUND: Function after revision total hip arthroplasty (THA) in failed metal-on-metal (MoM) hip resurfacing arthroplasty (HRA) is variable, but post-operative complication rates are reportedly high. We hypothesized HRA conversion to THA using the direct anterior approach (DAA) would be associated with optimal outcome. METHODS: Seventeen MoM-HRAs in 15 patients (seven males, eight females) were revised through the DAA. The mean age was 45 years (28-59 yrs)...

Background: Mast cell tumour, sebaceous gland adenoma, and less common squamous papilloma are skin tumours in ferrets ( Mustela putorius furo ), and early excisional surgery is usually the treatment of choice. The aim of our study was to investigate the effectiveness of electrochemotherapy (ECT), a new, minimally invasive non-surgical method, as first treatment option of different types of ferret skin tumours located on surgically difficult sites. Materials and methods: A 5-year-old castrated male ferret with two cutaneous masses, presenting 4 months apart and a 7-year-old spayed female ferret with two cutaneous masses, that appeared simultaneously on two locations are presented...

The treatment of melanoma requires complete removal of tumor cells and simultaneous tissue regeneration of tumor-initiated cutaneous defects. Herein, copper silicate hollow microspheres (CSO HMSs)-incorporated bioactive scaffolds were designed for chemo-photothermal therapy of skin cancers and regeneration of skin tissue. CSO HMSs were synthesized with interior hollow and external nanoneedle microstructure, showing excellent drug-loading capacity and photothermal effects. With incorporation of drug-loaded CSO HMSs into the electrospun scaffolds, the composite scaffolds exhibited excellent photothermal effects and controlled NIR-triggered drug release, leading to distinctly synergistic chemo-photothermal therapy of skin cancer both in vitro and in vivo...

Background: Inadequate release of retaining ligaments during facelift surgery may lead to an unnatural appearance. However, most facelift surgeons are hesitant in transecting these ligaments to avoid possible injury to facial subbranches. Objectives: In our surgical practice for modified composite flap rhytidectomy we use the finger-assisted malar elevation (FAME) technique in order to enable safe release of the zygomatic cutaneous ligaments through the prezygomatic space under direct vision...

BACKGROUND: Postoperative chylothorax occurs due to trauma to lymphatic vessels and can occur after any thoracic procedure. This study reviewed recent literature to evaluate the management and outcomes of surgical chylothorax in neonates. METHODS: PubMed database was searched for articles in English, Portuguese and Spanish from 2000 to 2016. Data were collected for surgery, chylothorax management, complications, mortality and length of hospital stay (LOS). RESULTS: Twenty studies offered 107 neonates: congenital diaphragmatic hernia (CDH) (n = 76, 71%), cardiac malformations (n = 25, 23...

The reverse sural flap has often been used for cutaneous coverage of the distal region of the leg and ankle. When the flap is performed in 2 stages, the vascular pedicle is exteriorized and later resected. Our goal was to assess the reverse sural flap performed in 2 stages regarding its viability and low morbidity along the flap-donor area. Eleven patients with cutaneous coverage loss found in the area between the distal third of the leg and ankle underwent cutaneous coverage surgery with a reverse-flow sural flap with an exteriorized pedicle, without violation of the skin between the base of the flap pedicle to the margin of the wound...

Hypertrophic scars and keloids are fibroproliferative disorders that may arise after any deep cutaneous injury caused by trauma, burns, surgery, etc. Hypertrophic scars and keloids are cosmetically problematic, and in combination with functional problems such as contractures and subjective symptoms including pruritus, these significantly affect patients' quality of life. There have been many studies on hypertrophic scars and keloids; but the mechanisms underlying scar formation have not yet been well established, and prophylactic and treatment strategies remain unsatisfactory...

Background and purpose - The use of local infiltration anesthesia (LIA) has become one of the cornerstones of rapid recovery protocols in total knee arthroplasty patients during the past decade. In total hip arthroplasty (THR), however, the study results are more variable and LIA has therefore not yet been generally accepted. There is no consensus on which structure should be infiltrated and the cutaneous nerves are generally neglected. Hence, we hypothesized a pain-reducing effect of specifically blocking these nerves...

Background: Currently, the standard protocol regarding the performance of procedures on patients receiving or having recently received isotretinoin (13- cis -retinoic acid) states that the procedures should not be performed. The recommendations in standard books and drug insert require discontinuation of isotretinoin for 6 months before performing cosmetic procedures, including waxing, dermabrasion, chemical peels, laser procedures, or incisional and excisional cold-steel surgery. These recommendations have been followed for over two decades despite little evidence for the stated increased risk of scarring...

Angiosarcoma, a rare cutaneous malignancy, frequently arises in the scalp of older individuals. Because it characteristically initially mimics benign disease, such as a bruise, definitive diagnosis in the early stages is difficult. Angiosarcoma of the scalp is highly malignant and often accompanied by lung metastases that cause hemopneumothorax. Although surgery has been the standard and most reliable curative treatment for angiosarcoma of the scalp, there is a high probability of local recurrence, even after wide surgical excision...

RATIONALE: Although lower-extremity surgeries are mainly performed under general or central neuraxial anesthesia, ultrasound-guided peripheral nerve block (PNB) can be a good alternative, especially for patients who require continuous anticoagulation treatment and present with poor cardiovascular conditions. PATIENTS CONCERNS: The patient required continuous anticoagulation treatment due to the high risk of thromboembolism and poor cardiovascular conditions. DIAGNOSES: The patient required lower-extremity amputation due to atherosclerotic and thromboembolic obstruction...

BACKGROUND: Chronic ulcers of the scalp have a variety of underlying pathologies. In case of cancer patients, a second malignancy must be excluded. CASE REPORT: A 78-year-old female patient presented to our department with a large soft tissue defect on the frontotemporal left side. The lesion was about 3 cm in diameter with exposed bone and inflammatory soft tissue on the edges of the defect. About 35 years ago, she had undergone a combined neurosurgery with skull trepanation and radiotherapy for an oligodendroglioma...

Epidermoid cysts are common benign lesions of hair-bearing, and less often glabrous skin. They can also occur in oral mucosa and internal organs. In case of cutaneous lesions, an epidermal punctum is a clinical diagnostic hallmark. The clinical presentation is variable leading to some differential diagnoses. Diagnosis of epidermoid cysts needs histopathological confirmation - not only of the potential of malignant transformation. The treatment of choice is surgery. We report a retrospective analysis of 2159 epidermoid cysts treated surgically...
