Abstract
A 44-year-old female patient with a familial adenomatous polyposis (FAP) was diagnosed with a cribriform morular thyroid carcinoma (CMTC). We observed within the very necrotic tumor a small but distinct poorly differentiated carcinomatous component. As expected, next generation sequencing of both components revealed a homozygous APC mutation and in addition, a TERT promoter mutation. A TP53 mutation was found exclusively in the CMTC part, while the poorly differentiated component showed a clonal evolution, harboring an activating PIK3CA mutation and copy number gains of BRCA2, FGF23, FGFR1, and PIK3CB-alterations which are typically seen in squamous cell carcinoma. The mutational burden in both components was low, and there was no evidence for microsatellite instability. No mutations involving the mitogen-activated protein kinase (MAPK) pathway, typically seen in papillary thyroid carcinomas, were detected. Immunohistochemically, all tumor parts were negative for thyroglobulin, providing further evidence that this entity does not belong to the follicular epithelial cell-derived thyroid carcinoma group. CD5 was negative in the poorly differentiated component, making a relation to intrathyroidal thymic carcinoma rather unlikely. However, since this marker was seen in the morules, a loss in the poorly differentiated component and a relation to the ultimobranchial body cannot be excluded either. After total thyroidectomy and radioiodine ablation, the patient was disease-free with no residual tumor burden on 2-year follow-up.

Abstract
ABSTRACT We present the case of a 68-year-old woman with a painful tibial tumor and fatigue. Histology and laboratory studies were consistent with a brown tumor secondary to initially unrecognized, severe primary hyperparathyroidism. 18F-fluorocholine PET/CT revealed a large hypermetabolic parathyroid mass and multiple bone foci considered as brown tumors. Unilateral neck exploration confirmed a large parathyroid adenoma. Serum calcium and parathyroid hormone levels normalized quickly, and symptoms subsided gradually after parathyroidectomy. Brown tumors are a rare complication of severe hyperparathyroidism. 18F-fluorocholine PET/CT allows the localization of parathyroid adenomas and brown tumors, and can be used as a single imaging modality.

Abstract
PURPOSE Hyperparathyroidism (HPT) is a common disorder. A cure can only be achieved by removing all diseased glands. It is critical to localize the hyperfunctioning glands exactly to prevent extensive surgical exploration. The number of false negative/inconclusive results in standard imaging techniques is high. We aimed to evaluate the diagnostic accuracy of 18F-Fluorocholine-PET in combination with contrast-enhanced CT (FCH-PET/CT) and its sensitivity in patients with primary, secondary/tertiary, and familial HPT with negative and/or discordant findings in ultrasound and/or 99mTc-sestamibi scintigraphy/SPECT/CT. METHODS A total of 96 patients with HPT and negative/equivocal conventional imaging were referred for FCH-PET/CT. In this retrospective, single institution study, 69 patients, who have undergone surgery and histopathologic workup, were analyzed. Of the 69 patients included, 60 patients suffered from primary HPT, four from secondary or tertiary HPT, and five from familial HPT. Sensitivities, positive predictive values, and accuracies were calculated. RESULTS Sensitivity/positive predictive value (PPV) per lesion was 87.5/98.3% for primary HPT, 75/100% for secondary/tertiary HPT and 25/66.7% for familial HPT. Sensitivity/PPV per patient was 91.5/98.2% for primary HPT, 100/100% for secondary/tertiary HPT and 50/100% for familial HPT. All patients showed normalized serum calcium levels in the postoperative period. The follow-up rate was 97%. Of the patients included in the study, 58 of 60 patients with primary HPT, and four of four patients with secondary/tertiary HPT showed normal calcium and parathyroid hormone (PTH) levels after six months and were cured. Of the patients with familial HPT, four of five patients were cured. CONCLUSION Diagnostic accuracy of 18F-Fluorocholine-PET/CT for patients with pHPT is excellent. 18F-Fluorocholine-PET/CT is a valuable tool for endocrine surgeons to optimize the surgical treatment of patients with hyperparathyroidism.

Abstract
This European expert consensus statement provides recommendations for the diagnosis and management of primary hyperparathyroidism (PHPT), chronic hypoparathyroidism in adults (HypoPT), and parathyroid disorders in relation to pregnancy and lactation. Specified areas of interest and unmet needs identified by experts at the second ESE Educational Program of Parathyroid Disorders (PARAT) in 2019, were discussed during two virtual workshops in 2021, and subsequently developed by working groups with interest in the specified areas. PHPT is a common endocrine disease. However, its differential diagnosing to familial hypocalciuric hypercalcemia (FHH), the definition and clinical course of normocalcemic PHPT, and the optimal management of its recurrence after surgery represent areas of uncertainty requiring clarifications. HypoPT is an orphan disease characterized by low calcium concentrations due to insufficient PTH secretion, most often secondary to neck surgery. Prevention and prediction of surgical injury to the parathyroid glands are essential to limit the disease-related burden. Long-term treatment modalities including the place for PTH replacement therapy and the optimal biochemical monitoring and imaging surveillance for complications to treatment in chronic HypoPT, need to be refined. The physiological changes in calcium metabolism occurring during pregnancy and lactation modify the clinical presentation and management of parathyroid disorders in these periods of life. Modern interdisciplinary approaches to PHPT and HypoPT in pregnant and lactating women and their newborns children are proposed. The recommendations on clinical management presented here will serve as background for further educational material aimed for a broader clinical audience, and were developed with focus on endocrinologists in training.

Abstract
Abstract
Objective
Hyperparathyroidism (HPT) is a common endocrine disorder. Definitive cure can only be reached by surgical removal of all diseased glands. The surgical strategy and management continue to evolve. Exact preoperative localization of hyperfunctioning glands is of paramount importance to prevent unnecessary surgical exploration. Unfortunately, the number of false negative or inconclusive results in standard imaging techniques is rather high. The aim of this study is to evaluate the diagnostic accuracy of 18F-Fluorcholine-PET/CT (FCH-PET/CT) and its sensitivity in a large cohort of patients with primary as well as secondary/tertiary and familial HPT with negative and/or discordant findings in ultrasound and/or 99mTc-sestamibi scintigraphy/SPECT/CT.
Methods
Between 2015 and 2020 96 patients with HPT and negative/equivocal conventional imaging were referred for FCH-PET/CT. 69 patients who have undergone surgery and histopathologic workup were analyzed in this retrospective single institution study. 60 patients suffered from primary HPT, 4 from secondary or tertiary HPT and 5 from familial HPT. Sensitivities, positive predictive values, and accuracies were calculated.
Results
All patients showed normalized serum calcium levels in the direct postoperative period.
50 of 60 patients (8 results are awaited) with primary HPT and 4 of 4 patients with secondary/tertiary HPT showed normal calcium levels after 6 months and were cured. 4 of 5 patients with familial HPT were cured as well while 1 patient deceased before 6 month follow up. Sensitivity per lesion for primary HPT was 88%, for secondary/tertiary HPT 75% and for familial HPT 75%, respectively. Sensitivity per patient was 92% for primary HPT, 100% for secondary/tertiary HPT and 50% for familial HPT, respectively. Positive predictive value was 98% in primary HPT and 100% in secondary/tertiary HPT and 100% in familial HPT as well.
Conclusion
Diagnostic accuracy of 18F-Fluorcholine-PET/CT for patients with primary as well as secondary/tertiary and familial hyperparathyreoidism ist excellent . 18F-Fluorcholine-PET/CT is a valuable tool for endocrine surgeons to optimize the surgical treatment of patients with hyperparathyroidism.

Abstract
Hintergrund Seit 2015 erfolgt in Europa mithilfe des EUROCRINE®-Registers eine systematische Dokumentation endokrin-chirurgischer Operationen. Ziel dieser ersten Auswertung war eine Darstellung der Versorgungsrealität für Nebenniereneingriffe in einem homogenen Versorgungsumfeld, entsprechend des deutschsprachigen Raums – bzw. des Präsenzgebiets der Chirurgischen Arbeitsgemeinschaft Endokrinologie (CAEK) der Deutschen Gesellschaft für Allgemein- und Viszeralchirurgie (DGAV) – einschließlich einer Analyse der Adhärenz zu geltenden Therapieempfehlungen. Methodik Es erfolgte eine deskriptive Analyse der präoperativen Diagnostik, der angewandten Operationstechniken sowie der zugrunde liegenden histologischen Entitäten der zwischen den Jahren 2015 und 2019 über EUROCRINE® in Deutschland, Österreich und der Schweiz dokumentierten Nebennierenoperationen. Ergebnisse In den insgesamt 21 teilnehmenden Kliniken des deutschsprachigen EUROCRINE®-Gebiets wurden 658 Operationen an Nebennieren durchgeführt. In 90 % erfolgten unilaterale, in 3 % bilaterale Adrenalektomien und in 7 % andere Resektionsverfahren. Die in 41 % der Operationen dokumentierte histologische Hauptdiagnose war das adrenokortikale Adenom. In 15 % lagen maligne Befunde zugrunde (einschließlich 6 % Nebennierenrindenkarzinome (ACC) und 8 % Nebennierenmetastasen). 23 % der Operationen erfolgten bei Phäochromozytomen. Diese wurden zu 82 % minimal-invasiv operiert, Nebennierenrindenkarzinome lediglich zu 28 % und Nebennierenmetastasen zu 66 %. Schlussfolgerung Überraschenderweise wurden nach Nebennierenadenomen und Phäochromozytomen an dritthäufigster Stelle Nebennierenmetastasen unterschiedlicher Primärtumoren reseziert. 28 % der ACC waren für minimal-invasive Techniken vorgesehen, wobei 20 % dieser Fälle eine Konversion zur offenen Operation erforderten. Die aktuelle Analyse deckte Diskrepanzen zwischen Versorgungsrealität und Leitlinienempfehlungen auf, aus denen sich zahlreiche Fragestellungen ergeben, welche nun in ein überarbeitetes EUROCRINE®-Modul zur Dokumentation von Nebennierenoperationen einfließen werden.

Abstract
Modern diagnosis and therapy of benign thyroid diseases Abstract. Benign thyroid diseases continue to be widespread endocrine disorders. Early recognition of their symptoms and exact diagnosis are the prerequisite of targeted therapy and minimal impairment of the patient's well-being. Drug treatment, radioiodine therapy, thermal ablation procedures and surgery have been shown to be successful treatment options. As guidelines for diagnosis and treatment of patients continue to evolve, an interdisciplinary approach ensures optimal diagnosis and management on every step in the care for these patients. We present three clinical scenarios for benign thyroid disease: the symptomatic goitre, the painful thyroid and the thyroid with hyperthyroidism.

Abstract
BACKGROUND Hypoparathyroidism is a rare and disabilitating disorder characterized by hypocalcemia and low parathyroid hormone levels. Most of the cases occur as a result of the removal of parathyroid glands or damage to the glands during neck surgery. More rare causes include nonsurgical causes such as autoimmune or genetic diseases. METHOD In this review, a panel of experts presents the current state of diagnosis and therapy of hypoparathyroidism and explains practical aspects of caring for the affected patients. RESULTS Common signs and symptoms are abnormal sensations and increased excitability in the lower limbs, paresthesia of perioral areas and nocturnal leg cramps. Renal complications frequently occur, but also basal ganglia calcification. Treatment consists of administration of vitamin D analogs in combination with 0.5-1.0 g calcium daily. An adjunctive treatment with the in April 2017 approved recombinant human parathyroid hormone (1-84) is an option for patients whose hypoparathyroidism is difficult to control by conventional treatment alone. Initially and after dose changes follow-up controls should be performed at least every 2 weeks, in well-controlled patients or in the case of chronic progression every 3-6 months.

Abstract
PURPOSE To compare the accuracy of planar scintigraphy, single photon emission computed tomography (SPECT), SPECT-CT, and positron emission tomography (PET) with C-11 methionine for the pre-operative detection of parathyroid adenomas. MATERIALS AND METHODS We retrospectively evaluated the pre-operative studies of 60 patients with primary (n=56) and secondary (n=4) hyperparathyroidism. In 25/60 patients (Group 1), only planar scans were obtained, and additional SPECT and SPECT-CT were carried out in 35/60 patients (Group 2). PET or PET-CT with C-11 methionine was conducted in 8/60 patients (Group 3). RESULTS The results of the planar scans (Group 1) were true positive in 19/25 patients and false negative in 6/25 patients (sensitivity per patient, 76%). Histopathology confirmed 27 adenomas and two hyperplasia. Planar imaging identified 20/29 of these pathologies, whereas 9/29 were missed (sensitivity per adenoma, 69%). SPECT (Group 2) results were true positive in 34/35 patients and false negative in only one case (sensitivity per patient, 97%). On a lesion-based analysis, 38 adenomas were identified, and two were missed (sensitivity per adenoma, 95%). The sensitivities of SPECT and SPECT-CT were equal; however, SPECT-CT provided superior topographic information. C-11 methionine PET (Group 3) results were true positive in all eight patients. In one case, surgery confirmed two ipsilateral adenomas, only one of which was identified by PET (sensitivity per patient, 100%; per adenoma, 88.9%). CONCLUSION SPECT is superior to planar imaging. SPECT-CT has identical sensitivity compared to SPECT alone, but it provides additional topographic information. The sensitivity of PET appears to be even higher compared to SPECT. In the case of negative scintigraphic findings and proven hyperparathyroidism, additional C-11 methionine PET or PET-CT is recommended.

Abstract
BACKGROUND The secreted liver protein fetuin-A (AHSG) is up-regulated in hepatic steatosis and the metabolic syndrome. These states are strongly associated with low-grade inflammation and hypoadiponectinemia. We, therefore, hypothesized that fetuin-A may play a role in the regulation of cytokine expression, the modulation of adipose tissue expression and plasma concentration of the insulin-sensitizing and atheroprotective adipokine adiponectin. METHODOLOGY AND PRINCIPAL FINDINGS Human monocytic THP1 cells and human in vitro differenttiated adipocytes as well as C57BL/6 mice were treated with fetuin-A. mRNA expression of the genes encoding inflammatory cytokines and the adipokine adiponectin (ADIPOQ) was assessed by real-time RT-PCR. In 122 subjects, plasma levels of fetuin-A, adiponectin and, in a subgroup, the multimeric forms of adiponectin were determined. Fetuin-A treatment induced TNF and IL1B mRNA expression in THP1 cells (p<0.05). Treatment of mice with fetuin-A, analogously, resulted in a marked increase in adipose tissue Tnf mRNA as well as Il6 expression (27- and 174-fold, respectively). These effects were accompanied by a decrease in adipose tissue Adipoq mRNA expression and lower circulating adiponectin levels (p<0.05, both). Furthermore, fetuin-A repressed ADIPOQ mRNA expression of human in vitro differentiated adipocytes (p<0.02) and induced inflammatory cytokine expression. In humans in plasma, fetuin-A correlated positively with high-sensitivity C-reactive protein, a marker of subclinical inflammation (r = 0.26, p = 0.01), and negatively with total- (r = -0.28, p = 0.02) and, particularly, high molecular weight adiponectin (r = -0.36, p = 0.01). CONCLUSIONS AND SIGNIFICANCE We provide novel evidence that the secreted liver protein fetuin-A induces low-grade inflammation and represses adiponectin production in animals and in humans. These data suggest an important role of fatty liver in the pathophysiology of insulin resistance and atherosclerosis.

Abstract
OBJECTIVE Several well-accepted classification systems are available for diabetic foot ulcers. However, there are only a few and scientifically not validated severity scores. The aim of this study was to establish a new wound-based clinical scoring system for diabetic foot ulcers suitable for daily clinical practice anticipating chances for healing and risk of amputation. RESEARCH DESIGN AND METHODS Four clinically defined parameters, namely palpable pedal pulses, probing to bone, ulcer location, and presence of multiple ulcerations, were prospectively assessed in 1,000 consecutive patients. In the next step, a new diabetic ulcer severity score (DUSS) was created from these parameters. Palpable pedal pulses were categorized by the absence (scored as 1) or presence (scored as 0) of pedal pulses, while probing to bone was defined as yes (scored as 1) or no (scored as 0). The site of ulceration was defined as toe (scored as 0) or foot (scored as 1) ulcer. Patients with multiple ulcerations were graded as 1 compared with those with single ulcers (scored as 0). The DUSS was calculated by adding these separate gradings to a theoretical maximum of 4. Wounds were followed-up for 365 days or until healing or amputation if earlier. Probability of healing and risk of amputation were calculated by the Kaplan-Meier method. RESULTS Uni- and multivariate analyses showed a significantly higher probability of healing for patients with palpable pulses, no probing to bone, toe ulcers, and absence of multiple ulcerations. When patients were divided into subgroups with the same DUSS, we found significantly different probabilities for healing. We showed a decreasing probability of healing for ulcers with a high DUSS, concurrent with increasing amputation rates. An increase in the DUSS by one score point reduced the chance for healing by 35%. Similarly, the higher the ulcer score, the larger the initial wound area, the longer the wound history, and the more likely the need for surgery or hospitalization. CONCLUSIONS The DUSS categorizes different ulcers into subgroups with specific severity and similar clinical outcome. Using this score, the probabilities for healing, amputation, need for surgery, and hospitalization are predictable with high accuracy. This might be useful for the anticipation of health care costs and for comparison of subgroups of patients in clinical studies.

Abstract
BACKGROUND Clinical pathways are a new initiative intended to reduce costs while maintaining or even improving the quality of care. Based on treatment guidelines, patient pathways display an optimal sequence of staff actions in the preoperative, operative, and postoperative in- and outpatient treatment. METHODS In this study, patient pathways were developed for selected elective general surgical disease entities following a new modular approach. All elements of care and their direct costs to the hospital were identified. Multidisciplinary teams of physicians, nurses, and administrative staff constructed and implemented the patient pathways. RESULTS In the 1-year pilot phase, we developed and implemented 7 pathways with 16 subpathways: open herniorrhaphy, laparoscopic cholecystectomy and fundoplication, thyroidectomy, surgical treatment of diverticulitis and colon carcinoma and kidney transplantation. CONCLUSIONS Patient pathways combine the management of care, hospital processes, and costs in a new integrated concept. Patient pathways streamline and standardize care, facilitate communication, and contribute to cost control efforts.

Abstract
For many years, lactate has been known to accelerate collagen deposition in cultured fibroblasts and, without detailed explanation, has been presumed to stimulate angiogenesis. Similarly, hypoxia has been linked to angiogenic effects and collagen deposition from cultured cells. Paradoxically, however, wound angiogenesis and collagen deposition are increased by breathing oxygen and decreased by hypoxia. Lactate accumulates to 4-12 mM in wounds for several reasons, only one of which is the result of hypoxia. Oxygen in wounds is usually low but can be increased by breathing oxygen (without change in lactate). We have reported that lactate elicits vascular endothelial growth factor (VECF) from macrophages, as well as collagen, some heat shock proteins, and VECF from endothelial cells, and collagen from fibroblasts, even in the presence of normal amounts of oxygen. Hypoxia exerts many of these same effects in cultured cells. In this study, we elevated extracellular lactate in wounds by implanting purified solid-state, hydrolysable polyglycolide. A steady-state 2-3 mM additional elevation of lactate resulted. With it, there was a significant short-term elevation of interleukin-1beta, a long-term elevation of VECF (2x) and transforming growth factor-beta1 (2-3x), a 50% elevation in collagen deposition, and a large reduction of insulin-like growth factor-1 (- 90%). We propose that lactate induces a biochemical "perception" of hypoxia and instigates several signals that activate growth factor/cytokine signals while the continued presence of molecular oxygen allows endothelial cells and fibroblasts to reproduce and deposit collagen. The data are consistent with ADP-ribosylation effects and oxidant signaling. (WOUND REP REG 2003;11:504-509)

Abstract
HYPOTHESIS Wound care can be prospectively recorded on a large scale if a standardized wound documentation system is established. Based on such a documentation system, a network of specialized wound care centers can generate a large and valid database of wound characteristics, wound-healing dynamics, and wound care. DESIGN A clinical prospective analysis. SETTING Ten German specialized surgical wound care centers. PATIENTS AND METHODS In a 2-year pilot phase, 4175 patients with 7051 chronic nonhealing wounds were documented using a new computerized system and treated following defined standards. RESULTS A total of 1761 diabetic, 1349 venous, 1146 ischemic, 1079 pressure, and 759 postoperative nonhealing wounds and 957 ulcers with other causes were prospectively documented. Chronicity of ulceration was shown by the long wound duration of 433 days (range, 14-1867 days). Wound documentation was well integrated into daily practice, as shown by a mean +/- SD documentation time of 5.7 +/- 2.2 minutes per visit. A multivariate analysis of factors known to interfere with wound healing revealed significant effects of patient compliance, grading of wound depth, and patient age (P<.001 for all). CONCLUSIONS The German Wound Net achieved, for the first time, centralized and prospective documentation of more than 7000 chronic wounds treated according to defined guidelines. This new concept of a network of specialized wound care centers working with standardized treatment plans and prospective documentation of chronic wounds may open a new dimension for wound-healing studies and may represent an optimal platform for multicenter trials.

Abstract
The marine Microbacterium species HP2 (DSM 12583), isolated from the sponge Halichondria panicea, is able to produce a glucosylmannosyl-glycerolipid when grown on a complex medium with glucose. Optimizing the carbon sources in shake flask experiments has shown that glycerol affords the highest specific glycoglycerolipid production. The product yield approached 300 mg/L or 25 mg/g biomass upon scaling up in a 40-L bioreactor volume. The native diglycosyl-glycerolipid GGL.2 strongly inhibited growth of the tumor cell lines HM02 and Hep G2 (50% inhibition at 0.4 to 3 microg/mL), while the related deacylated compound (GG.2) showed a potent anti-tumor-promoting activity.

Abstract
OBJECTIVE Subcapsular liver hematoma formation has been reported in less than 2% of pregnancies complicated by HELLP (hemolysis, elevated liver enzymes, low platelets) syndrome. The purpose of this study was to identify the main diagnostic and therapeutic options for management of these patients. STUDY DESIGN In this 10-year retrospective review, we performed a computer-directed search of all cases of confirmed HELLP syndrome with hepatic hematoma treated in the surgical department of our tertiary care referral medical center. RESULTS Five patients with subcapsular liver hematoma in HELLP syndrome could be identified. All patients received transabdominal ultrasound, computed tomography, or magnetic resonance imaging. Conservative treatment was successful in three patients. Emergency surgical intervention was necessary in two patients, including one liver transplantation. CONCLUSION The case series shows the full diagnostic spectrum with transabdominal ultrasound, computed tomography, and magnetic resonance imaging, as well as the different therapeutic options varying from conservative therapy to operative management, including liver transplantation.

Abstract
Deep groin infections after prosthetic vascular surgical procedures represent a serious complication of surgical practice. Septicemia and/or erosive hemorrhage can both be consequences. In this situation, removal of the graft appears to be the only option. However, if the infection is detected early (type Szilagyi III), local treatment to eradicate the infection could serve as an alternative. Twenty-four patients with confirmed infection of the soft tissue adjacent to the prosthetic material in the groin were treated locally by implantation of a vacuum sponge system. Duration of this treatment was 2 weeks. All patients showed excellent tissue granulation of the wound area and the microbial stains were negative at the end of therapy. In 21 patients the wound could be primarily closed after explantation of the sponge. Three patients underwent open treatment because of a skin defect. After 12 months, the wounds had healed well in all patients. Histologic evaluation revealed a physiological healing process. Deep soft tissue infections of the groin adjacent to prosthetic vascular material (type Szilagyi III) can be treated effectively and safely with the vacuum sponge system. The treatment is inexpensive, easy to perform, and the initial vascular reconstruction can be preserved.

Abstract
Wound problems are common in the elderly. We hypothesized that age-related decrements in blood levels of components of the insulin-like growth factor (IGF) system are reflected in the wound environment. In this prospective, observational study IGF-I, IGF-II, IGF-binding protein-2, IGF-binding protein-3, and acid labile subunit were measured by immunoassays in the wound fluid and plasma of young (23.5 +/- 3.3 years) and elderly (78.9 +/- 6.2 years) patients before and daily for 4 days after elective surgery. IGFs, IGFBP-3, and acid labile subunit in plasma were significantly lower in the elderly group (p < 0.0001). The decrements of these proteins in plasma were reflected in corresponding decrements of 25-70% in the wound fluid of elderly patients (p < 0.0001). Additionally, bioavailability of IGF-I was less in the aged. The IGF parameters in the wound displayed a constant ratio with those of blood, suggesting that blood contributes a major share of the IGF that enters the wound during the initial phase of healing. The current data adds to accumulating evidence that a decline in the IGF system in aged patients contributes to the healing deficits observed in the elderly.

Abstract
Chondromas of the soft tissue are uncommon, benign tumors. They are most frequently found adjacent to periarticular tissues or tenosynovium with a predilection for the hands and feet. We report a case of a patient with a large, increasing tumor of the left foot. Because of subjective complaints and mechanical irritation the patient was scheduled for surgery. The preoperative radiological work-up showed popcorn like clusters of calcifications around the dorsum of the foot. The tumor mass was reduced using several incisions. Histology showed soft tissue chondromatosis of the foot without malignancy. Following the operative procedure, the patient was free of pain and able to wear normal shoes. This case illustrates the clinical and radiological characteristics as well as the surgical treatment of progressive soft tissue chondromatosis.

HYPOTHESIS Anti-inflammatory corticosteroids significantly impair wound healing. Retinoids partially, but significantly, reverse this effect. Little is known about the mechanism of steroid retardation or retinoid reversal. We hypothesized that corticosteroids lower transforming growth factor-beta (TGF-beta) and insulin-like growth factor-I (IGF-I) levels and tissue deposition in wounds and that retinoids stimulate corticosteroid-impaired TGF-beta and IGF-I release and collagen production. DESIGN Randomized controlled trial. SETTING Wound healing research laboratory. PARTICIPANTS Animal study. INTERVENTIONS Four wire mesh wound cylinders were implanted subcutaneously into the backs of 72 male Sprague-Dawley rats. Wound healing was impaired by a single subcutaneous injection of 6 mg of methylprednisolone acetate (Depo-Medrol). Two preparations of retinoids were used in separate experiments: all-trans-retinoic acid and 9-cis-retinoic acid that were fed orally. MAIN OUTCOME MEASURES Hydroxyproline content was measured in the healing tissue and TGF-beta and IGF-I levels were analyzed in the wound fluid. RESULTS Methylprednisolone treatment significantly decreased TGF-beta and IGF-I levels in the wound fluid and hydroxyproline content in the tissue (P<.05). Oral all-trans- and 9-cis-retinoic acid partially reversed the TGF-beta and IGF-I decrease and significantly increased hydroxyproline content toward normal levels (P<.05). Oral all-trans-retinoic acid enhanced collagen deposition, TGF-beta and IGF-I levels over normal chow fed control animals (P<.05). CONCLUSIONS Steroids and retinoids have antagonistic effects on growth factors and collagen deposition in wound healing. These effects can be relevant for treatment options in a clinical setting.

Abstract
The bacterium Microbacterium sp., isolated from the sponge Halichondria panicea, produced four unusual cell-associated glycoglycerolipids and one diphosphatidylglycerol when grown on marine broth and on artificial seawater media. The lipids were isolated by chromatography on silica columns and their structures elucidated using a combination of multidimensional NMR and MS techniques. The main compound was 1-O-acyl-3-[alpha-glucopyranosyl-(1-3)-(6-O-acyl-alpha-mannopyranosyl )]glycerol (GGL.2) with 14-methyl-hexadecanoic acid and 12-methyl-tetradecanoic acid positioned at C-6 of the mannose unit and at the glycerol moiety. Glycolipid production was correlated with growth and reached a maximum value of 200 mg/L when grown on artificial seawater medium with 20 g/L glucose. The main compound decreased the surface tension of water down to 33 mN/m and the interfacial tension of the water/n-hexadecane system down to 5 mN/m. In addition to this good surface-active behavior, the main glycoglycerolipid showed antitumor activities.

Abstract
OBJECTIVE To determine the rate of virological treatment failure with protease inhibitor therapy in unselected patients and to assess underlying risk factors. DESIGN AND SETTING Retrospective study in two German tertiary care treatment centres. PATIENTS A total of 198 HIV-infected patients treated with protease inhibitors in 1996. MAIN OUTCOME MEASURES Levels of HIV RNA 1-6 months after start of treatment; definition of treatment failure of < 1 log10 reduction in plasma HIV RNA within 6 months after starting protease inhibitor therapy; multivariate analysis of risk factors for treatment failures. RESULTS A total of 226 treatment episodes with protease inhibitors were evaluable (saquinavir, 83; ritonavir, 47; indinavir, 96). The rate of virological treatment failure was 44% (saquinavir, 64%; ritonavir, 38%; indinavir, 30%). In a multivariate analysis, the following independent risk factors for virological failure were found: CD4 cell count, pretreatment with antiretroviral drugs (number), and protease inhibitor (compound). The relative risk reduction for each CD4 cell count increase was 0.997 (P = 0.012), 2.64 for pretreatment with one or two drugs versus no drug (P = 0.05), 2.97 for pretreatment with more than two drugs versus no drug (P = 0.05), and 4.62 for treatment with saquinavir versus indinavir (P = 0.001). CONCLUSION An unexpectedly high rate of virological treatment failure of protease inhibitor therapy was found in an unselected cohort of HIV-infected patients. Response to antiretroviral combination therapy in normal clinical practice may considerably differ from results of randomized clinical trials. Further studies are warranted to find optimal treatment strategies for both initial and salvage therapy.

Abstract
BACKGROUND "Respiratory burst" activity, ie, O2- production, is dependent on PO2, temperature, pH, and glucose concentrations within the physiologic range. OBJECTIVES To determine whether environmental conditions characteristic of wounds may limit human neutrophil respiratory burst metabolism and to clarify the degree to which bactericidal oxidant production depends on local PO2. METHODS Human blood and wound neutrophils were stimulated with phorbol myristate acetate. Oxygen consumption and superoxide production were measured over a range of 30 to 300 mm Hg PO2, 0 to 40 mmol/L glucose, pH 6.0 to 8.0, and 30 degrees C to 37 degrees C. The apparent Michaelis Menten constant for oxidant production with respect to PO2 was calculated. RESULTS Oxygen consumption and O2- production were dependent on PO2 throughout the range tested. Half-maximal oxidant production occurred in the range of 45 to 80 mm Hg PO2 and maximal at PO2 higher than 300 mm Hg. These data agree with the highest previous estimates. Oxidant generation was also dependent on pH, temperature, and glucose concentration, but to a lesser extent. CONCLUSIONS Leukocyte bacterial killing capacity as measured by oxygen consumption and superoxide production are substantially impaired at the low oxygen tensions often found in wounds. Changes in pH, temperature, and glucose concentration have lesser but nonetheless significant consequences. The data provide a plausible mechanism for the vulnerability of some wounds to infection and for the previous finding that increasing oxygen tension at wound sites enhances bactericidal function. Thus, the data serve as a basis for future studies on prevention of wound infection.

Abstract
This brief clinical report illustrates the case of a 50-y-old male patient with severe radiation-induced renal and intestinal fibrosis who received glutamine-enriched total parenteral nutrition (TPN). The patient had end-stage renal disease and, therefore, underwent a kidney transplant. In the postoperative course the patient developed signs of bowel obstruction and cachexia. He received two courses of glutamine-enriched TPN before he underwent surgery for small bowel stenosis. Postoperatively, the patient received a third course of glutamine-enriched TPN. During the patient's hospital course the following indexes were monitored: patient's weight, serum concentrations of protein, albumin, and trialglycerol. Intestinal permeability was assessed with the lactulose-mannitol sugar test (L-M test). We measured changes in the patient's weight and the L-M test. We hypothesize that glutamine-enriched TPN may have been beneficial in the hospital course of this critically ill patient and may have influenced the patient's intestinal function and permeability.

Abstract
The object of this animal study was to examine and further develop the expanded polytetrafluoroethylene wound healing model. The goal was to increase its potential for assessing wound healing by increasing yield, reducing variability, establishing the elements of a standard technique, and further testing its ability to detect variations of healing which have clinical significance. Expanded polytetrafluoroethylene implants of various dimensions and fabrications and several implantation and sterilization techniques were compared in rats. Hydroxyproline, DNA, and protein deposition into the expanded polytetrafluoroethylene implants as parameters for wound healing were assessed. Additionally, a 4 cm skin incision for tensile strength assessment was created. Wound healing was assessed under normal and corticosteroid-impaired healing conditions. The highest yield of collagen was found in the stiffer fabrication of expanded polytetrafluoroethylene with the larger pore size and after the more traumatic implantation technique of incisional placement. Variability was unaffected by fabrication, implantation technique, indexing by various geometric dimensions of the implant, sterilization, or sampling techniques. Variability was the same in the individual animals as in groups of animals. The expanded polytetrafluoroethylene method also detects the influence of antiinflammatory corticosteroids and reflects the tensile strength of incisional wounds made in other sites in the same animal.
