Abstract
BACKGROUND Soft tissue sarcomas (STSs) are a heterogeneous group of tumors. Wide surgical resection is standard, often combined with neoadjuvant chemotherapy, radiotherapy, or both. Studies have shown the predictive value of tumor necrosis in bone sarcoma (BS); however, the role of necrosis in STS after neoadjuvant therapies is still unclear. This study aimed to investigate the role of chemo- and radiotherapy in the formation of tumor necrosis and to evaluate the influence of tumor necrosis on overall survival and local recurrence-free survival. Data from BS patients and patients who did not receive neoadjuvant therapy were compared. METHODS A total of 779 patients with STS or BS were treated surgically. In all patients, tumor-specific factors such as type, size, or grading and the type of adjuvant therapy were documented. Local recurrence (LR), the diagnosis of metastatic disease, and survival during follow-up were evaluated. RESULTS A total of 565 patients with STS and 214 with BS were investigated. In STS, 24.1% G1 lesions, 34.1% G2 lesions, and 41.8% G3 lesions were observed. Two hundred twenty-four of the patients with STS and neoadjuvant therapy had either radiotherapy (RTx) (n = 80), chemotherapy (CTx) (n = 93), or both (n = 51). Three hundred forty-one had no neoadjuvant therapy at all. In STS, tumor necrosis after neoadjuvant treatment was significantly higher (53.5%) than in patients without neoadjuvant therapy (15.7%) (p < 0.001). Patients with combined neoadjuvant chemo-/radiotherapy had substantially higher tumor necrosis than those with radiotherapy alone (p = 0.032). There was no difference in tumor necrosis in patients with combined chemo-/radiotherapy and chemotherapy alone (p = 0.4). The mean overall survival for patients with STS was 34.7 months. Tumor necrosis did not influence survival in a subgroup of G2/3 patients. In STS with no neoadjuvant therapy and grading of G2/3, the correlation between necrosis and overall survival was significant (p = 0.0248). There was no significant correlation between local recurrence (LR) and necrosis. CONCLUSION STS shows a broad spectrum of necrosis even without neoadjuvant chemo- or radiotherapy. After CTx or/and RTx necrosis is enhanced and is significantly pronounced with a combination of both. There is a trend toward higher necrosis with CTx than with RTx. Grading substantially influences the necrosis rate, but necrosis in soft-tissue sarcoma following neoadjuvant therapy does not correlate with better survival or a lower local recurrence rate, as in bone sarcomas.

Abstract
PURPOSE Although there is a theoretical risk of skin seeding during surgical resection of soft tissue sarcomas (STSs), current consensus guidelines recommend against routine use of bolus during radiation therapy (RT). However, the risk of skin recurrence has not been systematically assessed. We aimed to assess the patterns of local recurrence (LR) in patients with STS treated with surgery with or without RT. METHODS AND MATERIALS We performed a retrospective analysis of adults with STSs evaluated at our institution between 2007 and 2021. For patients who developed LR, the depth was evaluated. Progression-free survival and overall survival were analyzed from time of first LR using the Kaplan-Meier method. Cumulative incidence of distant metastasis was calculated with competing risk analysis from date of LR. RESULTS Of the 206 patients evaluated, 20 had LR (9.7%). Among patients with LR, 5 patients (25.0%) were treated with surgery alone and 15 patients (75.0%) with surgery and RT. In patients treated with RT, 46.7% had preoperative RT, 53.3% had postoperative RT, and bolus was used in 46.7%. Surgical margins were close (<1 mm) in 4 patients (20.0%) and positive in 10 patients (50.0%). LR occurred in the deep subfascial tissue in 9 patients (45%), subcutaneous tissue in 10 patients (50.0%), and skin in 1 patient (5.0%). The patient with a skin recurrence was treated with surgery alone, and the tumor involved the skin at presentation. In patients treated with RT, LR occurred within the RT field in 13 patients (86.7%). At 1 year after LR, progression-free survival was 70.3%, overall survival was 81.7%, and cumulative incidence of distant metastasis was 5.9%. CONCLUSIONS Skin recurrences were rare after surgical resection of STSs and only occurred in a tumor that involved the skin at initial presentation. These findings support current recommendations against routine use of bolus in STSs not involving the skin at presentation.

Abstract
Venous malformations (VMs) are part of the spectrum of vascular malformations composed of ectatic venous channels. VMs of the oral cavity in pediatric patients are relatively rare but reportedly carry a higher rate of rupture than in adults. We describe the management of an 18-month-old boy with VM who presented with a localized dome-shaped swelling measuring approximately 9.4 mm by 7.4 mm in the anterior third of the palate. Management with sclerotherapy using an intralesional injection of three percent sodium tetradecyl sulphate was used to treat the lesion with minimum armamentarium, cost, and complication.

Abstract
BACKGROUND Postsclerotherapy neoangiogenesis telangiectatic matting (TM) occurs in up to 24% of individuals treated by sclerotherapy. Although the etiology is unknown, obstructive flow factors, angiogenic factors, estrogen, inflammatory, and endogenous factors have all been postulated to play a role in its pathogenesis. OBJECTIVE The aim of the study was to ascertain the presence or absence of estrogen and progesterone receptors in postsclerotherapy TM lesions and thus substantiate their possible role in the pathogenesis of TM. METHODS Ten women, median age 37.7 years, were included in the study population who developed TM following a single sclerotherapy treatment session employing Sotradecol 0.25% for class I-II telangiectasia/venulectasia. Four of 10 patients had a history of previous hormonal therapy or pregnancy in the previous 12 months prior to entering into the study. Three millimeter punch biopsies were taken at 12 weeks posttreatment and assayed for estrogen and progesterone receptors by the ERICA and PRICA (estrogen/progesterone immune cytochemical assay) techniques. RESULTS Zero of 10 patients were positive for estrogen/progesterone receptors as assayed by the ERICA/PRICA technique in biopsied sites of postsclerotherapy TM. CONCLUSION Although estrogen and progesterone may play an indirect role in the development of postsclerotherapy TM via vasodilatory or secondary angiogenic or cytokine release mechanisms, they do not appear to play a primary role in promoting postsclerotherapy neoangiogenesis as demonstrated in this study.

Abstract
The purpose of this study was to develop a large animal model for chronic osteomyelitis, suitable for toxicologic research and therapeutic intervention studies. Osteomyelitis was induced in 52 healthy adult Texel sheep by injecting a sclerosing agent and a hemolytic strain of Staphylococcus aureus into the proximal tibial marrow cavity. Evaluation was done by clinical, radiologic, bacteriologic, and histologic parameters for 3 months. Clinical signs of infection consisted of localized soft tissue swelling, pain during the acute phase, and limping in all sheep. Radiologic features were moderate to extensive periosteal reaction, cortical lysis, mild to extensive new bone formation, and frequent development of sequestra limited to the proximal part of the tibia. Cultures were positive for the same strain of Staphylococcus aureus in all but one sheep. Histology showed chronic active inflammation, osteolysis, new woven bone formation, debris, clusters of bacteria, and surrounding granulation tissue. It was necessary to administer a single prophylactic dose of antibiotics 1 hour after surgery to prevent fatal sepsis. It was concluded that sheep are a suitable model for chronic osteomyelitis.

Abstract
PURPOSE To test a method of nonsurgical sterilization. MATERIALS AND METHODS A hydrogel that forms an in situ plug by phase inversion of a polymer solution was placed into fallopian tubes of eight rabbits by means of transvaginal rabbits by means of transvaginal fluoroscopic fallopian tube catheterization. The rabbits were bred, and the presence of embryos was confirmed with palpation and at autopsy. RESULTS Seven of the eight rabbits became pregnant. Six of these rabbits contained embryos in the control uterus but not in the uterus on the side of the hydrogel injection. The seventh rabbit had embryos in both uteri, but the hydrogel had been expelled. All seven tubes that contained hydrogel showed evidence of acute and chronic salpingitis and a foreign-body reaction. The tube from which hydrogel had been expelled and the eight control tubes were not inflamed. CONCLUSION Transcervical catheter methods of tubal occlusion and sterilization are promising, but a non-reactive material is needed.

Abstract
BACKGROUND As sclerotherapy has become more of an exact science it has become appropriate to dilute various sclerosing solutions to produce the least concentration of sclerosant producing effective endosclerosis of a given vessel diameter--the minimal sclerosant concentration. OBJECTIVE In this setting it has become necessary to take into account various microbiologic considerations. Contamination of infusates is the most common cause of epidemic device-related bloodstream infections. With these considerations in mind, the following study was undertaken to determine the bacterial and fungal content of varied concentrations of four commonly employed sclerotherapy agents. METHODS Dilutions were made of hypertonic saline 23.4% to 11.7% with both bacteriostatic water and 0.9% normal saline, Polidocanol 0.5% to 0.25% with bacteriostatic water, sodium tetradecyl sulfate 1.0% to 0.5% with bacteriostatic water, and polyiodide iodide 2% to 1% with bacteriostatic water under sterile conditions. Each sclerosant was analyzed for bacterial, fungal, and spore content at determined time intervals with standardized utilization indices for up to 3 months. RESULTS At each sclerosant concentration for sodium chloride, polidocanol, sodium tetradechol sulfate, and polyiodide iodide at each study design time interval for sampling all bacterial and fungal cultures remained sterile. CONCLUSIONS With appropriate aseptic techniques we may dilute sclerosing solutions to desired concentrations that will remain sterile for a period of at least 3 months under daily usage conditions.

Abstract
We present a prospective single-blind trial of sclerotherapy for hydroceles with tetradecyl sulphate and rolitetracycline as sclerosants. Twenty-seven hydroceles were treated with tetradecyl sulphate and 28 with rolitetracycline. The median follow-up was 13 months. There were no statistically significant differences between the 2 drugs in respect of cure rate and complications. The overall cure rate for both drugs was 96%. Complications were rare and common to both drugs. Tetradecyl sulphate and rolitetracycline were found to be equally effective as sclerosants.

Abstract
The absorbance maximum, lambda max, of a local anesthetic, benzyl alcohol, is shifted to longer wavelengths when solvent polarity is decreased. The shift was approximately a linear function of the dielectric constant of the solvent. This transition in electronic spectra according to the microenvironmental polarity is used to analyze benzyl alcohol binding to surfactant micelles. A facile method is devised to estimate the micelle/water partition coefficient from the dependence of lambda max of benzyl alcohol on surfactant concentrations. The effective dielectric constants of the sodium decyl sulfate, dodecyl sulfate and tetradecyl sulfate micelles were 29, 31 and 33, respectively. The partition coefficient of benzyl alcohol between the micelles and the aqueous phase was 417, 610 and 1089, respectively, in the mole fraction unit. The pressure dependence of the partition coefficient was estimated from the depression of the critical micelle concentration of sodium dodecyl sulfate by benzyl alcohol under high pressure up to 200 MPa. High pressure squeezed out benzyl alcohol molecules from the micelle until about 120 MPa, then started to squeeze in when the pressure was further increased. The volume change of benzyl alcohol by transfer from the aqueous to the micellar phase was calculated from the pressure dependence of the partition coefficient. The volume change, estimated from the thermodynamic argument, was 3.5 +/- 1.1 cm3.mol-1 at 298.15 K, which was in reasonable agreement with the partial molal volume change determined directly from the solution density measurements, 3.1 +/- 0.2 cm3.mol-1. Benzyl alcohol apparently solvates into the micelles close to surface without losing contact with the aqueous phase.

Abstract
Few techniques are available for the study of persistent ulceration. In this report we describe a suitable animal model. Intracutaneous injection of sodium tetradecyl sulphate (STD) in guinea-pig flank skin caused a reproducibly sized and shaped superficial ulcer that healed approximately three times more slowly than punch biopsies of comparable size. Histological, immunofluorescent and autoradiographic studies showed that it possesses many of the morphological and kinetic features of human stasis ulceration. STD ulcers treated with a streptokinase/streptodornase solution healed with less slough and tended to re-epithelialize more rapidly than controls, but ulcers treated with dextran polymer beads or a stabilized hydrogen peroxide cream healed at the same rate as their control.

Abstract
Percutaneous transhepatic embolization of varices (PTEV) has proved to be effective in the control variceal bleeding, particularly in Child's Class C Category patients whose bleeding was not adequately controlled by pitressin perfusions. PTEV, using Gel-Foam soaked in sodium tetradecyl sulfate, controlled acute variceal bleeding in 71--95% of patients and appears to be more effective as an embolizing agent than bucrylate, which controlled 43--57%. Considering the poor condition of the patients particularly during acute bleeding episodes, PTEV is a relatively safe therapeutic procedure that buys time for the surgeons to perform a decompressive shunt electively as definitive surgery. A one-year recurrent bleeding rate of 30% and a two year recurrence of 37.5% was noted. Thus, for long term control of variceal bleeding, a surgical decompressive shunt is recommended in addition to PTEV.

Abstract
1. The affinity of tetradecyl sulfate for many unfolded proteins is greater than that of dodecyl sulfate. 2. It is the presence of tetradecyl sulfate that results in the staining of proteins by pinacryptol yellow seen by Stoklosa and Latz (Stoklosa, J.T. and Latz, H.W. (1974) Biochem. Biophys. Res. Commun. 58, 74--79), as some tetradecyl sulfate remains associated with proteins during electrophoresis at room temperature (as opposed to dodecyl sulfate which, within the limit of detection, is completely removed). 3. Tetradecyl sulfate has a greater capacity to dissociate protein aggregates which consist of identical peptide chains, such as Glycophorin dimers and bovine serum albumin dimers, than does dodecyl sulfate.
