BACKGROUND: Cell-assisted lipotransfer has been promisingly applied to restore soft-tissue defects in plastic surgery; however, the harvesting of stromal vascular fraction increases morbidity and poses potential safety hazards. The authors investigated whether adding indomethacin, an antiinflammatory proadipogenic drug, to the fat graft at the time of transplantation would enhance the final graft volume compared with cell-assisted lipotransfer. METHODS: In vitro, human adipose-derived stem cells were cultured in conditioned growth media supplemented with various doses of indomethacin to investigate adipogenesis and the expression of the adipogenic genes...

BACKGROUND: Postoperative rebleeding after thyroid surgery is a rare but a serious complication. The aim of this study was to ascertain the extent to which postoperative pressure could be used as detector for rebleeding after thyroid surgery. METHODS: Thirty-two patients with thyroidectomy or hemithyroidectomy were considered prospectively. In the course of surgery, a pressure microsensor (3PN Probe Spiegelberg) was implanted into the postoperative cavity and data were collected for special activities and stress situations over the first 48 h postoperatively...

Sarcomas are rare diseases of the head and neck region, representing around 1% of all malignancies. Amongst them, ameloblastic fibrosarcoma (AFS) is of even greater rarity, with less than 100 cases reported in the literature. Consequently, no standard treatment or guidelines have been made available. Surgery is often performed as primary therapy, but may be limited due to anatomical or functional reasons. We present a case of AFS successfully treated by postoperative radiation therapy. A detailed case study is provided, followed by a review of the English-language literature focusing on the role of radiation therapy...

Glioma is the most common primary malignant tumor of the central nervous system, which results in both a poor prognosis and outcome because of the aggressive progression of disease, growth and resistance to surgery, chemotherapy, and radiotherapy. MiR-140-5p is a small, non-coding single-stranded RNA molecule, which was previously studied in the settings of human tongue cancer, hepatocellular carcinoma, and colorectal cancer. However, detailed data that formally demonstrate the contribution of miR-140-5p to glioma development are missing...

Growth hormone (GH) is an essential element for normal growth. However, reports of normal growth without GH have been made in patients who have undergone brain surgery for craniopharyngioma. Normal growth without GH can be explained by hyperinsulinemia, hyperprolactinemia, elevated leptin levels, and GH variants; however, its exact mechanism has not been elucidated yet. We diagnosed a female patient aged 13 with combined pituitary hormone deficiency (CPHD) caused by pituitary stalk interruption syndrome (PSIS)...

In this retrospective study, data of 2,435 patients who received fentanyl and ropivacaine-based patient-controlled epidural analgesia (PCEA) for pain relief after elective surgery under general or spinal anesthesia were reviewed. Differences in postoperative pain, incidence of patient-controlled analgesia (PCA)-related adverse effects, and risk factors for the need for rescue analgesics for 48 hours postsurgery in young (age 20-39 years) and elderly (age ≥70 years) patients were evaluated. Although there were no significant differences in postoperative pain intensity between the two groups until 6 hours postsurgery, younger patients experienced greater postoperative pain intensity compared with older patients 6-48 hours postsurgery...

In this paper, we demonstrate a wavelength widely tunable gain-switched Er<sup>3+</sup>-doped ZBLAN fiber laser around 2.8 μm. The laser can be tuned over 170 nm (2699 nm~2869.9 nm) for various pump power levels, while maintaining stable μs-level single-pulse gain-switched operation with controllable output pulse duration at a selectable repetition rate. To the best of our knowledge, this is the first wavelength tunable gain-switched fiber laser in the 3 μm spectral region with the broadest tuning range (doubling the record tuning range) of the pulsed fiber lasers around 3 μm...

OBJECTIVE: The typical recurrence of a glioblastoma occurs locally, usually within 2 cm from the original lesion. With the improvement of surgery techniques, more aggressive surgical strategies have become feasible, resulting in a significantly increased rate of complete resection. Therefore, we were interested, if these improvements are also reflected by the tumor recurrence pattern. PATIENTS AND METHODS: Inclusion criteria were: first diagnosis of glioblastoma, followed by standard adjuvant radio-chemotherapy and histologically proven tumor recurrence...

The goal of this paper is to report our experience with hindfoot fractures using our specially developed boot, with a follow-up of 557 cases. This boot works like the well-known Allgöwer-Röck ortheses (ARO), but is a hybrid between a boot and an orthesis. It allows full weightbearing without using crutches and completely protects an acutely operated hind foot fracture, hind foot arthrodesis or a hind foot fracture which is suitable for conservative treatment. In its first generation, this boot was custom made and used in 408 cases, from March 1999 to February 2011...
