    Title Epithelioid Hemangioendothelioma of the Spine: Report of Two Cases and Review of the Literature.
    Date February 2009
    Journal British Journal of Neurosurgery

    We report two patients with spinal epithelioid hemangioendothelioma (EH), an uncommon vascular, potentially malignant tumour. Neurological signs, diagnostic images, surgical techniques and complications, histology and the role of adjuvant therapy are discussed. Primary manifestation of EH of the vertebral column is rare. Thorough preoperative clinical and radiological workup, radical surgical excision, and close postoperative follow-up are recommended.

    Title The Effect of Haem in Red and Processed Meat on the Endogenous Formation of N-nitroso Compounds in the Upper Gastrointestinal Tract.
    Date September 2007
    Journal Carcinogenesis

    Red and processed meat (PM) consumption increases the risk of large bowel cancer and it has been demonstrated that haem in red meat (RM) stimulates the endogenous production of N-nitroso compounds (NOCs) within the human intestine. To investigate whether N-nitrosation occurs in the upper gastrointestinal tract, 27 ileostomists were fed diets containing no meat, or 240 g RM or 240 g PM in a randomly assigned crossover intervention design carried out in a volunteer suite. Endogenous NOC were assessed as apparent total N-nitroso compounds (ATNC) in the ileostomy output. ATNC concentration in the diets was 22 microg ATNC/kg (RM) and 37 microg ATNC/kg (PM), and 9 microg ATNC/kg in the no meat diet. Levels significantly increased to 1175 microg ATNC/kg SEM = 226 microg ATNC/kg) following the RM (P=0.001) and 1832 microg ATNC/kg (SEM=294 microg ATNC/kg) following PM (P<0.001) compared to the no meat diet (283 microg ATNC/kg, SEM=74 microg ATNC/kg). ATNC concentrations in the ileal output were equivalent to those measured in faeces in similarly designed feeding studies. Supplementation with either 1 g ascorbic acid or 400 IU alpha-tocopherol had no effect on the concentration of ATNC detected in the ileal output. In in vitro experiments, N-nitrosomorpholine (NMor) was formed in the presence of nitrosated haemoglobin, at pH 6.8 but not in the absence of nitrosated haemoglobin. These findings demonstrate that haem may facilitate the formation of NOC in the absence of colonic flora in the upper human gastrointestinal tract.

    Title Variability in Fecal Water Genotoxicity, Determined Using the Comet Assay, is Independent of Endogenous N-nitroso Compound Formation Attributed to Red Meat Consumption.
    Date May 2006
    Journal Environmental and Molecular Mutagenesis

    Red meat consumption causes a dose-dependent increase in fecal apparent total N-nitroso compounds (ATNC). The genotoxic effects of these ATNCs were investigated using two different Comet assay protocols to determine the genotoxicity of fecal water samples. Fecal water samples were obtained from two studies of a total of 21 individuals fed diets containing different amounts of red meat, protein, heme, and iron. The first protocol incubated the samples with HT-29 cells for 5 min at 4 degrees C, whereas the second protocol used a longer exposure time of 30 min and a higher incubation temperature of 37 degrees C. DNA strand breaks were quantified by the tail moment (DNA in the comet tail multiplied by the comet tail length). The results of the two Comet assay protocols were significantly correlated (r = 0.35, P = 0.003), however, only the second protocol resulted in detectable levels of DNA damage. Inter-individual effects were variable and there was no effect on fecal water genotoxicity by diet (P > 0.20), mean transit time (P = 0.588), or weight (P = 0.705). However, there was a highly significant effect of age (P = 0.019). There was no significant correlation between concentrations of ATNCs in fecal homogenates and fecal water genotoxicity (r = 0.04, P = 0.74). ATNC levels were lower in fecal water samples (272 microg/kg) compared to that of fecal homogenate samples (895 microg/kg) (P < 0.0001). Failure to find dietary effects on fecal water genotoxicity may therefore be attributed to individual variability and low levels of ATNCs in fecal water samples.

    Title Primary Extradural Epithelioid Leiomyosarcoma of the Cervical Spine: Case Report and Literature Review.
    Date April 2006
    Journal Neurosurgery

    OBJECTIVE AND IMPORTANCE: No case of primary epithelioid leiomyosarcoma involving the spine has been reported previously. CLINICAL PRESENTATION: A 61-year-old Nigerian woman presented with progressive spastic quadriparesis and acute urinary retention. Her only medical history included a total abdominal hysterectomy for fibroids 10 years earlier in Nigeria. Results of the general examination were normal. Pyramidal spastic quadriparesis (3/5) with a sensory level at C5-C6 was found neurologically. Magnetic resonance imaging scans of the brain and spine revealed extradural cord compression at C3-C5 as the sole abnormality. This was caused by a large, soft tissue mass arising from the erector spinae muscles, which was predominantly isointense on T1-weighted images, of mixed intensity on T2-weighted images, and homogenously enhanced after gadolinium contrast agent administration. There was an associated signal change in the cord at C3-C4. Computed tomography confirmed the predominantly soft tissue involvement, but with bone erosion and infiltration within the posterior elements of C4. Systemic screening for cancer was negative. INTERVENTION: At decompressive laminectomy, urgently undertaken under corticosteroid cover, an excessively vascularized, soft tissue tumor was subtotally excised, after which independent walking and normal sphincter function were regained within 1 week. Four weeks later, a complete macroscopic tumor excision was undertaken, incorporating lateral mass (C3-C6) and C2 pedicle screw stabilization, along with iliac crest bone grafting. The patient's neurological status continued to improve. However, while awaiting radical radiotherapy, the patient declined further treatment and returned to her native Nigeria. Histopathological findings were consistent with an epithelioid leiomyosarcoma. CONCLUSION: This is the first reported case of a primary craniospinal epithelioid leiomyosarcoma.

    Title A Spectrum of Behaviour in Silent Corticotroph Pituitary Adenomas.
    Date October 2005
    Journal British Journal of Neurosurgery

    Silent corticotroph adenomas (SCA) are pituitary tumours positive on immunohistochemical staining for ACTH but without clinical evidence of Cushing's disease in the patient. Previous reports suggest that these tumours may behave in a more aggressive way then other pituitary adenomas. We have followed the natural history of SCA and assessed whether histopathological indices predict tumour behaviour. We identified 22 patients in whom trans-sphenoidal surgery was performed for a non-functioning adenoma (NFA) with positive immunostaining for ACTH between 1990 and 2000 and examined the history of their disease. Patients were followed up for a mean of 4.8 years. A total of 86.7% of patients had documented visual deficits at presentation. In four cases hypercortisolaemia was observed later in the course of the disease. Two patients died as a result of their SCA and 33.3% of tumours recurred. Recurrence was more frequent in patients treated with adjuvant radiotherapy. Pathological indices (increased mitotic range and Ki-67) did not predict recurrence or malignant transformation. We suggest that certain 'silent' corticotroph tumours may have the potential for ACTH secretion leading to hypercortisolaemia at a later stage in the disease. The possibility of transformation to a more aggressive tumour needs to be considered in all SCA.

    Title Transcranial Surgery for Pituitary Tumors Performed by Sir Victor Horsley.
    Date July 2003
    Journal Neurosurgery

    OBJECTIVE: To describe the clinical details and the operative method used in pituitary tumors by Sir Victor Horsley (1857-1916), which represent the earliest attempts at pituitary surgery. METHODS: Horsley's case books and postmortem records, archived at the National Hospital, Queen Square, London, were studied for patients with a primary diagnosis of a pituitary tumor admitted during the period 1886 to 1916 who were treated surgically. Contemporary records of nonpituitary cases were also examined to study aspects of Horsley's operative method. RESULTS: Four patients (three men and one woman) underwent craniectomy for removal of a pituitary tumor via the subtemporal approach between 1904 and 1907. All four patients experienced significant impairments of visual fields or visual acuity; one patient had severe trigeminal neuralgia. Evidence of acutely raised intracranial pressure was present in one patient. All patients underwent craniectomy under chloroform anesthesia. One patient died on the day of surgery, and the postmortem findings are presented. In the other three patients, neurological morbidity was recorded in the postoperative period in the form of new cranial nerve deficits, monoparesis with dysphasia, and seizures. The patient with trigeminal neuralgia experienced partial relief and was readmitted later for reexploration and Gasserian ganglionectomy via the same route. Four contemporary nonoperative cases of pituitary tumor are also presented. CONCLUSION: These cases provide insight into the presentation and operative treatment of pituitary tumors during the pre-Halsted era.

    Title Haem, Not Protein or Inorganic Iron, is Responsible for Endogenous Intestinal N-nitrosation Arising from Red Meat.
    Date June 2003
    Journal Cancer Research

    Many N-nitroso compounds (NOC) are carcinogens. In this controlled study of 21 healthy male volunteers, levels of NOC on a high (420 grams) red meat diet were significantly greater (P = 0.001) than on a low (60 grams) meat diet but not significantly greater when an equivalent amount of vegetable protein was fed. An 8-mg supplement of haem iron also increased fecal NOC (P = 0.006) compared with the low meat diet, but 35-mg ferrous iron had no effect. Endogenous N-nitrosation, arising from ingestion of haem but not inorganic iron or protein, may account for the increased risk associated with red meat consumption in colorectal cancer.

    Title Effect of Vegetables, Tea, and Soy on Endogenous N-nitrosation, Fecal Ammonia, and Fecal Water Genotoxicity During a High Red Meat Diet in Humans.
    Date January 2003
    Journal Nutrition and Cancer

    Red meat increases colonic N-nitrosation, and this may explain the positive epidemiological relationship between red meat intake and colorectal cancer risk. Vegetables, tea, and soy have been shown to block N-nitroso compound (NOC) formation and are associated with protection against colorectal cancer. To determine whether these supplements affect fecal NOC excretion during consumption of a high red meat (420 g/day) diet, 11 male volunteers were studied over a randomized series of 15-day dietary periods. Seven of these subjects completed a further dietary period to test the effects of soy (100 g/day). Soy significantly suppressed fecal apparent total NOC (ATNC) concentration (P = 0.02), but supplements of vegetables (400 g/day as 134 g broccoli, 134 g brussels sprouts, and 134 g petits pois) and tea extract (3 g/day) did not affect mean levels of fecal ATNC, nitrogen and ammonia excretion, and fecal water genotoxicity. However, fecal weight was increased (P < 0.001) and associated with reduced transit time (r = 0.594, P < 0.0001), so that contact between ATNC, nitrite, and ammonia and the large bowel mucosa would have been reduced. Longer transit times were associated with elevated fecal ATNC concentrations (r = 0.42, P = 0.002). Fecal nitrite was significantly suppressed during the tea supplement compared with the meat-only (P = 0.0028) and meat + vegetables diets (P = 0.005 for microgram NO2/g).

    Title Papillary Glioneuronal Tumour in a 4-year-old.
    Date August 2002
    Journal Pediatric Neurosurgery

    The recently described 'papillary glioneuronal tumour' is not currently included in the WHO classification of tumours of the CNS. We present the youngest recorded case to date, and only the 3rd documented in the paediatric population. The incorporation of this neoplasm into the WHO classification would facilitate its wider recognition, providing an opportunity to elucidate its natural history and determine an evidence-based approach to treatment.

    Title Adverse Operative Events in Neurosurgical Training: Incidence, Trends and Proposals for Prevention.
    Date October 2001
    Journal British Journal of Neurosurgery

    We prospectively studied the adverse operative events encountered during the first 4.5 years of a single neurosurgeon's career (JP). We investigated the incidence of these events and their distribution over time, and recorded risk factors in causation. Twenty-three adverse events were identified in 728 cases studied. These all occurred in one of four categories of operation: craniotomy, shunt placement, spinal surgery and stereotactic biopsy. The incidence of adverse operative events varied between 5.8% for spinal operations to 9.5% for stereotactic biopsy. There was evidence of a reducing incidence of adverse operative events over time in some operative groups. The two categories with the highest incidence of adverse operative events were the same two categories with the lowest number of assisted cases per 100 operations performed.

    Title Dose-dependent Effect of Dietary Meat on Endogenous Colonic N-nitrosation.
    Date March 2001
    Journal Carcinogenesis

    Human male volunteers were studied in a metabolic facility whilst they were fed randomized controlled diets. In eight volunteers there was a significant increase in faecal apparent total N:-nitroso compounds (ATNC) and nitrite excretion (P < 0.0001 and P = 0.046, respectively) when randomized doses of meat were increased from 0 to 60, 240 and 420 g/day over 10 day periods. Mean (+/- SE) faecal ATNC levels were 54 +/- 7 microg/day when the diets contained no meat, 52 +/- 11 microg/day when the diets contained 60 g meat/day, 159 +/- 33 microg/day with 240 g meat and 199 +/- 36 microg/day with 420 g meat. Higher concentrations of NOC were associated with longer times of transit in the gut (r = 0.55, P = 0.001) and low faecal weight (r = -0.51, P = 0.004). There was no significant decline in levels in individuals fed 420 g meat for 40 days. The exposures found on the higher meat diets were comparable with other sources of N:-nitroso compounds (NOC), such as tobacco smoke. Many NOC are known large bowel initiators and promotors in colon cancer, inducing G-->A transitions in codons 12 and 13 of K-ras. Endogenous NOC formation, combined with prolonged transit times in the gut, may explain the epidemiological associations between high meat/low fibre diets and colorectal cancer risk.

    Title Effect of Meat and Resistant Starch on Fecal Excretion of Apparent N-nitroso Compounds and Ammonia from the Human Large Bowel.
    Date January 1998
    Journal Nutrition and Cancer

    N-nitroso compounds are produced in the human large intestine, but little is known about the dietary modulation of their synthesis at this site. The effects of meat and resistant starch on the fecal excretion of N-nitroso compounds, measured as apparent total N-nitroso compounds (ATNC), were therefore investigated in a crossover study involving eight healthy men. Three controlled diets that differed in the amount of meat (40 or 600 g) and resistant starch (37 g added to 600 g meat diet) were fed in random order, and fecal ATNC, as well as fecal ammonia and parameters of bowel function, were measured after 19 days of dietary adaptation. Mean ATNC excretion during the high-meat period was 114 micrograms/day, three times that during the low-meat period of 35 micrograms/day (p = 0.02); ammonia excretion was twice that during the low-meat period: 2.9 vs. 1.4 mmol/day (p = 0.03). The fecal ATNC were dissolved in the fecal water, and 45% had a molecular weight < 3,000. The addition of readily fermentable resistant starch to the high-meat diet significantly increased stool output from 118 to 153 g/day and decreased fecal pH from 7.2 to 6.6 but had no significant effect on fecal ATNC (151 micrograms/day), ammonia (3.7 mmol/day), whole gut transit time, urinary nitrate, or plasma urea. ATNC produced in the large bowel in association with a high-meat intake could represent an important source of DNA-damaging alkylating agents in the human large bowel.

    Title 1h and 15n Nmr Resonance Assignments and Solution Secondary Structure of Oxidized Desulfovibrio Desulfuricans Flavodoxin.
    Date September 1996
    Journal Journal of Biomolecular Nmr

    Sequence-specific 1H and 15N resonance assignments have been made for 137 of the 146 nonprolyl residues in oxidized Desulfovibrio desulfuricans [Essex 6] flavodoxin. Assignments were obtained by a concerted analysis of the heteronuclear three-dimensional 1H-15N NOESY-HMQC and TOCSY-HMQC data sets, recorded on uniformly 15N-enriched protein at 300 K. Numerous side-chain resonances have been partially or fully assigned. Residues with overlapping 1HN chemical shifts were resolved by a three-dimensional 1H-15N HMQC-NOESY-HMQC spectrum. Medium- and long-range NOEs, 3JNH alpha coupling constants, and 1HN exchange data indicate a secondary structure consisting of five parallel beta-strands and four alpha-helices with a topology similar to that of Desulfovibrio vulgaris [Hildenborough] flavodoxin. Prolines at positions 106 and 134, which are not conserved in D. vulgaris flavodoxin, contort the two C-terminal alpha-helices.

    Title Does Increased Endogenous Formation of N-nitroso Compounds in the Human Colon Explain the Association Between Red Meat and Colon Cancer?
    Date July 1996
    Journal Carcinogenesis

    High red meat diets have been linked with risk of sporadic colorectal cancer; but their effects on mutations which occur in this cancer are unknown. G-->A transitions in K-ras occur in colorectal cancer and are characteristic of the effects of alkylating agents such as N-nitroso compounds (NOC). We studied th effect of red meat consumption on faecal NOC levels in eight male volunteers who consumed diets low or high in meat (60 or 600 g/day), as beef, lamb or pork, whilst living in a metabolic suite. Increased intake of red meat induced a significant (P<0.024) 3-fold increase from 40 + or - 7 to ab average of 113 + or - 25 microgram/day NOC, a range of exposure in faeces similar to that from tobacco-specific NOC in cigarette smoke. THe diets were isoenergetic and contained equal amounts of fat, but concentrations of heterocyclic amines were low. Faecal excretion of the promotor ammonia was significantly increased to 6.5 + or - 1.08 mmol/day. When the high red meat diets were supplemented with 20 g phytate-free wheat bran in six volunteers there was no reduction in NOC levels (mean 138 + or - 41 microgram/day NOC), but faecal weight increased. Higher starch and non-starch polysaccharide intakes reduced intraluminal cross-linking in microcapsules (r=-0.77) and reduced faecal pH (r=-0.64). In two volunteers there was no effect of 600 g white meat and fish o faecal NOC (mean low white meat diet 68 + or - 10 microgram/day, high white meat 56 + or -6 microgram/day nor on faecal nitrate, nitrite and iron. Faecal nitrite levels increased on changing from a white to red meat diet (mean high white meat diet 46 + or - 7 mg/day, high red meat diet mean 80 + or - 7 mg/day.) Increased endogenous production of NOC and precursors from increased red meat, but not white meat and fish, consumption may be relevant to the aetiology of colorectal cancer.

    Title Purification and Structural Characterization of the Cd11b/cd18 Integrin Alpha Subunit I Domain Reveals a Folded Conformation in Solution.
    Date September 1995
    Journal Febs Letters

    The alpha subunits of the leukocyte CD11/CD18 integrins contain an approximately 200 amino acid 'inserted' or I domain. The I domain of the cell-surface Mac-1 (CD11b/CD18) integrin has been shown to be the major recognition site for several adhesion ligands, including iC3b, fibrinogen, factor X, and ICAM-1. The I domain from the Mac-1 alpha subunit has been expressed in Escherichia coli as a soluble GST-fusion protein containing a factor Xa sensitive cleavage site. Analytical characterization of the purified I domain reveals that it is obtained in very high quality at high yields. CD and NMR spectra indicate that I domain adopts a predominantly folded structure in solution, independent of the remainder of the alpha subunit. Addition of Ca2+ and Mg2+ did not significantly perturb the structural conformation.

    Title Lactoperoxidase-catalyzed Oxidation of Thiocyanate Ion: a Carbon-13 Nuclear Magnetic Resonance Study of the Oxidation Products.
    Date November 1992
    Journal Biochimica Et Biophysica Acta

    Products formed from the lactoperoxidase (LPO) catalyzed oxidation of thiocyanate ion (SCN-) with hydrogen peroxide (H2O2) have been studied by 13C-NMR at pH 6 and pH 7. Ultimate formation of hypothiocyanite ion (OSCN-) as the major product correlates well with the known optical studies. The oxidation rate of SCN- appears to be greater at pH < or = 6.0. At [H2O2]/[SCN-] ratios of < or = 0.5, OSCN- is not formed immediately, but an unidentified intermediate is produced. At [H2O2]/[SCN-] > 0.5, SCN- appears to be directly oxidized to OSCN-. Once formed, OSCN- slowly degrades over a period of days to carbon dioxide (CO2), bicarbonate ion (HCO3-), and hydrogen cyanide (HCN). An additional, previously unrecognized product also appears after formation of OSCN-. On the basis of carbon-13 chemical shift information this new species is suggested to result from rearrangement of OSCN- to yield the thiooxime isomer, SCNO- or SCNOH.

    Title Peptide Nitrosation in Dilute Acid.
    Date January 1988
    Journal Iarc Scientific Publications

    Rates and products are reported for the nitrosation of simple dipeptides (glycylglycine, its ethyl ester and N-acetylglycylglycine) in dilute acid at 37 degrees C. The results suggest that conversion to a diazo derivative (which rapidly decomposes) is the most likely outcome of the gastric nitrosation of small proteins and peptides.

    Title Possible Underestimation of Nitrosatable Amine Levels in Artificial Saliva Extracts of Children's Rubber Pacifiers and Baby-bottle Teats.
    Date January 1988
    Journal Iarc Scientific Publications

    Children's pacifiers and baby-bottle nipples from various countries were analysed for their content of N-nitrosamines and nitrosatable amines. Using a method involving extraction with artificial saliva, several nitrosamines including N-nitrosodi-n-butylamine (NDBA), N-nitrosodiethylamine (NDEA), N-nitrosodimethylamine (NDMA) and N-nitrosomorpholine (NMOR) were detected in addition to the three nitrosatable amines dibutylamine (DBA), diethylamine (DEA) and dimethylamine (DMA). Upon nitrosation in artificial saliva, these amines produced not only the related N-nitrosamines but also relatively high levels of the corresponding nitramines--N-nitrodibutylamine (NTDBA), N-nitrodiethylamine (NTDEA) and N-nitrodimethylamine (NTDMA). Thus, both N-nitramines and N-nitrosamines should be measured after nitrosation; otherwise, the method probably underestimates the quantities of nitrosatable amines present in artificial saliva extracts. Whether N-nitramines, some of which have been shown to be both mutagenic and carcinogenic, are formed in the saliva of babies exposed to these products remains to be confirmed.

    Journal Medical Dosimetry : Official Journal of the American Association of Medical Dosimetrists

    Computerized tomography (CT)-assisted treatment planning for high-dose-rate (HDR) gynecological cancer treatments allows for better structure visualization and dose-volume histogram analysis definition. Problems associated with CT imaging are addressed. These pitfalls include the potential for multiple patient transfers and movement between applicator insertion, simulation, and treatment. Applicator CT imaging artifacts are also discussed. A modified transport table and a machined connection for a commercially available non-CT-compatible tandem and a CT-compatible ring applicator are described. These 2 modifications provide a safe and reliable method to utilize the advantages of CT imaging for gynecological HDR treatments.
