Abstract
BACKGROUND Personalized postoperative management of patients with pituitary adenomas requires an early risk stratification system. METHODS We reviewed 501 cases operated between 10/27/2011 and 5/5/2016 by a single neurosurgeon. We determined biochemical remission and tumor resection at 3 months, and biochemical recurrence, tumor recurrence, radiation and reoperation during follow-up. We considered age, gender, tumor diameter, cavernous sinus invasion (CSI) by MRI, diagnostic category (clinical, biochemical and immunohistochemical), and proliferation markers in a Cox proportional hazards model. We built predictive models with the significant parameters and used Kaplan-Meier survival curves for time-dependent analyses. RESULTS The 501 cases comprised 141 functional and 360 nonfunctional adenomas. Tumor diameter, CSI, and ki-67 index predicted long-term events. Model 1 (CSI, diameter ≥ 2.9 cm and ki-67 > 3%) identified 18 (3.6%) adenomas and predicted persistent hypersecretory syndrome and residual tumor with 98.7% specificity (OR 8.6; CI 3.0-24.7). Model 2 (ki-67 > 3% and CSI) identified 48 (9.6%) adenomas and had 93.1% specificity (OR 3.3; CI 1.8-6.0). Model 3 (ki-67 > 3%, mitoses and p53, former "atypical" adenoma) identified 26 (5.2%) adenomas and had 96.0% specificity (OR 2.3; CI 1.0-5.0). Model 1 best predicted the long-term event-free survival and was strengthened when Knosp 3-4 CSI grades were used. Model 2 better identified the smaller adenomas at risk. Among the WHO 2017 special PA subtypes, patients with silent corticotroph adenoma had a lower event-free survival than ACTH-negative nonfunctional adenomas. CONCLUSION Use of CSI, ki-67 and tumor diameter in prediction models facilitates tailored surveillance and management of patients with pituitary adenomas.

Abstract
BACKGROUND The incidence of infectious complications has not been previously compared for two types of common urinary catheters used in the long-term care setting: indwelling urethral catheters and suprapubic catheters. AIM To compare catheter-associated urinary tract infection (CAUTI) rates and multidrug-resistant organism (MDRO) colonization between nursing home residents with indwelling urethral and suprapubic catheters. METHODS Participants included 418 nursing home residents with an indwelling device enrolled in a previously published prospective targeted infection prevention study conducted between 2010 and 2013. Resident age, gender, function, comorbidities, and information on infections, antibiotic use, and recent hospitalizations were obtained at study enrolment, day 14, and every 30 days thereafter for up to one year. Microbiological samples were obtained from several anatomic sites at each visit. Cox proportional hazard models were adjusted for facility-level clustering and other covariates. FINDINGS In all, 208 study participants had an indwelling urinary catheter, contributing 21,700 device-days; 173 (83%) with a urethral catheter, 35 (17%) with a suprapubic catheter. After covariate adjustment, the suprapubic group had a lower incidence of CAUTI (6.6 vs 8.8 per 1000 device-days; P = 0.05), were half as likely to be hospitalized (hazard ratio (HR) = 0.46; P < 0.01) and were 23% less likely to have had antibiotics in the past 30 days (HR = 0.77; P = 0.02). Among residents catheterized ≥90 days, the mean number of MDROs isolated in the suprapubic group was significantly higher than in the urethral group (0.57 vs 0.44; P = 0.01). Ciprofloxacin-resistant Gram-negative bacilli were frequent in both groups. CONCLUSION Residents with a suprapubic catheter may have fewer CAUTIs, less hospitalization and less antibiotic use, but are more likely colonized with MDROs.

Abstract
Background
Hyperglycemia leading to increased oxidative stress is implicated in the increased risk for the development of macrovascular and microvascular complications in patients with type 1 diabetes mellitus.
Methods and Results
A random subcohort of 349 participants was selected from the
DCCT
/
EDIC
(Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications) cohort. This included 320 controls and 29 cardiovascular disease cases that were augmented with 98 additional known cases to yield a case cohort of 447 participants (320 controls, 127 cases). Biosamples from
DCCT
baseline, year 1, and closeout of
DCCT
, and 1 to 2 years post‐
DCCT
(
EDIC
years 1 and 2) were measured for markers of oxidative stress, including plasma myeloperoxidase, paraoxonase activity, urinary F
2α
isoprostanes, and its metabolite, 2,3 dinor‐8
iso
prostaglandin F
2α
. Following adjustment for glycated hemoblobin and weighting the observations inversely proportional to the sampling selection probabilities, higher paraoxonase activity, reflective of antioxidant activity, and 2,3 dinor‐8
iso
prostaglandin F
2α
, an oxidative marker, were significantly associated with lower risk of cardiovascular disease (−4.5% risk for 10% higher paraoxonase,
P
<0.003; −5.3% risk for 10% higher 2,3 dinor‐8
iso
prostaglandin F
2α
,
P
=0.0092). In contrast, the oxidative markers myeloperoxidase and F
2α
isoprostanes were not significantly associated with cardiovascular disease after adjustment for glycated hemoblobin. There were no significant differences between
DCCT
intensive and conventional treatment groups in the change in all biomarkers across time segments.
Conclusions
Heightened antioxidant activity (rather than diminished oxidative stress markers) is associated with lower cardiovascular disease risk in type 1 diabetes mellitus, but these biomarkers did not change over time with intensification of glycemic control.

Abstract
Psoriasis is a chronic inflammatory skin disorder which is generally not associated with scarring. We report two patients with long-standing severe anogenital psoriasis, that was associated with loss of the labia minora, thus clinically mimicking the scarring associated with lichen sclerosus. Histopathological finding were however, consistent with psoriasis with no evidence of lichen sclerosus. Elastic fibres were present and there was no evidence of abnormal collagen or fibrous tissue. The association of vulval psoriasis with scarring has not been reported previously.

Abstract
BACKGROUND Photodynamic therapy (PDT) using topical 5-aminolaevulinic acid (5-ALA) has been suggested as an effective and tissue-conserving method of treating carcinoma in situ of the vulva. OBJECTIVES To evaluate PDT in patients with vulval intraepithelial neoplasia type III (VIN III). METHODS Topical PDT was performed in six patients with VIN III. Five of the six patients had persistent disease following treatment with other modalities including 5-fluorouracil cream, cryotherapy, carbon dioxide laser ablation and excision. Each patient was treated once with a fluence of 150 J cm-2 using a broad-band light source (580-740 nm) 4 h after topical application of 20% 5-ALA. Patients were reviewed clinically at 1 month and 6 months after treatment. RESULTS All of the patients developed initial erythema of treated sites, three with subsequent erosions. All patients had clinically evident persistent VIN III at 1-month review. Five patients have subsequently undergone surgical treatment and one is regularly reviewed. CONCLUSIONS This small uncontrolled study indicates that, as currently administered, a single episode of topical PDT is not effective in the management of treatment-resistant VIN III.

Abstract
We report a large family with ichthyosis bullosa of Siemens (IBS) including eight affected members spanning three generations. The classical features of the disease were consistently observed with blistering, superficial peeling of the skin, and localized lichenified hyperkeratosis mainly confined to the limbs. Phenotypic variation, however, was also observed with some individuals exhibiting unusual clinical features. Specifically, the index patient was erythrodermic at birth; she subsequently developed a widespread pustular eruption. Erythroderma is classically absent in IBS and pustulation is very unusual. She also had hypertrichosis of the limbs, as did an affected female first cousin. This has not previously been reported in IBS. Electron microscopy showed complex aggregates of keratin in the spinous and granular layers associated, in places, with remarkably little cell lysis. Sequencing of genomic DNA revealed a mutation (E493K) in keratin 2e. A review of the literature on IBS indicates that E493K is the most commonly reported mutation to date and might represent a mutational hotspot for this disease.

Abstract
Mucous membrane pemphigoid (MMP) is an autoimmune blistering disease frequently associated with scarring of involved clinical sites. At present, therapeutic intervention in the form of immunomodulating or immunosuppressive agents is often reserved until the onset of significant inflammation and/or early cicatrization. We have therefore studied the clinical and immunopathological findings in 67 patients with MMP in order to try to establish a reliable prognostic indicator by which patients at high risk may be identified early in the disease. Inclusion criteria were a predominantly mucosal disease and the detection of IgG and/or C3 anti-basement membrane zone (BMZ) immunoreactants using immunofluorescence techniques. Patients were allocated to three disease subgroups on the basis of the modality and duration of therapeutic intervention required to achieve effective control of disease. In addition, at presentation and at each follow-up visit, a clinical score for severity of involved clinical sites was awarded and serum collected for indirect immunofluorescence (IIF). A dual circulating anti-basement membrane zone (anti-BMZ) antibody response with IgG and IgA was significantly associated with a more severe and persistent disease profile (P < 0.001). The odds ratios for requiring systemic therapy were: 11.6 among patients in whom there was a clinical score > or = 5 compared with a score < 5, and 31.3 and 66.9 among patients with IgG alone and both IgG and IgA, respectively, compared with negative IIF. The findings suggest that an assessment based upon a combination of site severity score and the presence of circulating IgG and IgA by IIF using 1 mol/L salt-split human skin substrate may be considered a useful prognostic indicator.

Abstract
An adaptation of the conventional procedure for fixation of brain impressions prior to rabies testing was developed using a microwave oven to fix slides in less than 1 min. A total of 2394 routine specimens were examined to evaluate the efficacy of microwave fixation of brain impressions as an aid to shortening the turnaround time for reporting. Slides were fixed for 55-60 s in a standard household microwave oven at 50%, power using phosphate buffered saline supplemented with 3% Tween 20 as a fixative medium. They were then stained using the standard rabies immunofluorescent staining procedure with minor modifications. This process potentially could allow results to be reported to submitters within 1.5 h after specimens arrive in the laboratory. Microwave fixation was in complete agreement with conventional acetone fixation for detection of positive rabies specimens.

Abstract
BACKGROUND Serum neutralization (Nt) is used most often to type enterovirus isolates, but it is labor-intensive, expensive, and supplies of reference antisera for Nt are limited. Alternative methods of enterovirus typing are needed. OBJECTIVES To investigate the use of indirect immunofluorescence (IFA) with commercially available monoclonal antibodies (MAbs) as an alternative to Nt for the identification of enteroviruses. STUDY DESIGN Two MAb blends (one for coxsackie B viruses and one for echoviruses 4, 6, 9, 11, 30, and 34) and a coxsackie A9 MAb were used to screen 465 clinical isolates over a period of two years. Virus isolates which tested positive with one of the blends were typed with the individual MAbs of the respective blend. Individual MAbs for polioviruses 1, 2, and 3 acquired late in the study were used to screen 45 viral isolates. RESULTS The antibodies identified 251/465 (54%) of the total number of isolates tested. IFA results for 451 of 465 viral isolates were in agreement with conventional identification methods. The sensitivity of the IFA screen using the MAb blends and coxsackie A9 MAb was 93% and the specificity was 99%. Thirteen discrepant isolates were negative by IFA, with twelve positive by Nt for echovirus 30 and one isolate positive by Nt for coxsackie A9. The remaining discrepant isolate was positive by IFA for both coxsackie A9 and coxsackie B5, but positive by Nt for coxsackie A9 only. CONCLUSIONS IFA is highly specific for the identification of enteroviruses, but may not be sensitive enough to identify all strains within an enterovirus type. Procedures which utilize an IFA screen and confirm final results by Nt decrease turnaround time and reduce the number of cell culture tubes required for the identification of each enterovirus isolate.

Abstract
A point mutation in the mtDNA-encoded ATP6 gene (T-->G at nt 8993) associated with Leigh syndrome in two pedigrees was found to decrease ADP-stimulated (state III) respiration and the ratio of ADP molecules phosphorylated to oxygen atoms reduced (ADP/O ratio) but did not affect 2,4-dinitrophenol (DNP)-uncoupled respiration, suggesting a defective mitochondrial H(+)-translocating ATP synthase. Intact mitochondria isolated from patient and control lymphoblastoid cell lines were tested for state III, ADP-limited (state IV), and DNP-uncoupled respiration with various substrates. Mitochondria isolated from patient lymphoblasts harboring 95-100% of mtDNAs carrying the nt 8993 T-->G mutation showed state III respiration rates 26-50% lower than controls while having normal DNP-uncoupled rates. This resulted in state III/DNP ratios of 0.52-0.70 in patient mitochondria versus 0.88-0.97 in controls. The ADP/O ratio was also decreased 30-40% in patient mitochondria. Patient lymphoblasts heteroplasmic for the nt 8993 mutation were enucleated by using Percoll gradients and the cytoplasts were fused to mtDNA-deficient (rho 0) cells by electric shock. Cybrid clones homoplasmic for the wild-type nucleotide (T) at nt 8993 gave state III/DNP and ADP/O ratios similar to those of control cybrids, whereas cybrid clones homoplasmic for the mutant nucleotide (G) showed a 24-53% reduction in state III respiration, a state III/DNP ratio of 0.53-0.64, and a 30% decrease in the ADP/O ratio. Thus, the reduced state III respiration rates and ADP/O ratios are linked to the T-->G mutation at nt 8993.

Abstract
Aberrant p53 immunoreactivity has been found in skin pre-malignancies and dysplasias such as Bowen's disease and actinic keratoses. Vulval lichen sclerosus (LS) has been reported to be pre-malignant, with an association of vulval carcinoma in 3% to 6% of patients. In contrast, non-genital LS appears to have no malignant potential. In this immunocytochemical study, we investigated p53 expression in 10 cases of histologically proven vulval LS and 9 cases of non-genital LS using the murine monoclonal antibody Do-1 raised against recombinant human p53 which reacts with both wild-type and mutant p53. None of the vulval specimens had epithelial dysplasia or malignancy. Normal vulval (7 cases) and non-genital skin (5 cases) were used as tissue controls, respectively. The cell proliferation index was also studied using the MIB 1 monoclonal antibody which detects the cell-cycle associated Ki-67 antigen. The technique of microwave irradiation for antigen unmasking was employed on formalin-fixed and paraffin-embedded tissues. There was a significant increase in p53 immunoreactivity in vulval LS (32.13 +/- 15.11 epidermal cells per 100 basal cells) compared to normal vulval skin (7.52 +/- 5.04 epidermal cells per 100 basal cells) (p < 0.001), whereas the MIB 1 labelling index was lower in vulval LS (39.45 +/- 15.88 epidermal cells per 100 basal cells) than in normal controls (86.26 +/- 32.31 epidermal cells per 100 basal cells) (0.001 < p < 0.01). In contrast, there was no significant difference in p53 immunoreactivity or MIB 1 labelling index between non-genital LS and normal controls.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The sequence and expression characteristics are described of a wilt-inducible gene in Arabidopsis thaliana. A1494 encodes a potential thiol protease whose mRNA accumulates rapidly in shoot tissue upon the loss of turgor. A1494 mRNA levels peaked after ca. 4 h and declined thereafter. Dehydration also induced rapid biosynthesis of the phytohormone abscisic acid (ABA), which continued for at least 9 h. Exogenous ABA induced the accumulation of A1494 mRNA, with kinetics similar to those after wilting. Rehydration of wilted shoots led to a rapid decline in the content of both ABA and A1494 mRNA. Wilting and ABA independently induced A1494 expression as evidenced by the effects of ABA and wilting on the ABA-deficient aba-1 and ABA-insensitive abi-1 and abi-3 genotypes. A1494 mRNA was not detectable in aba-1 shoots but accumulated rapidly after either wilting or ABA treatment, whereas the shoot ABA content was increased only by ABA treatment. ABA had no effect on A1494 mRNA levels in the abi-1 and abi-3 mutants but wilting did result in enhanced A1494 expression. Heat shock had only a minor effect on A1494 mRNA levels, whereas exposure to low temperature resulted in substantial accumulation of A1494 mRNA in wild-type shoots. However, this latter response, unlike that to drought, was mediated exclusively via ABA synthesis as demonstrated by the lack of A1494 mRNA accumulation in cold-treated aba-1 shoots.

Abstract
Three positive (PR1-3) and one negative (NR1) transcriptional control domain have been tentatively mapped in the promoter of the human F0F1-ATP synthase beta subunit gene (ATPsyn beta) in the context of expression in myogenic cells. Lipofection of promoter-chloramphenicol acetyltransferase fusion constructs into C2C12 myogenic cells revealed that two of the three positive domains (PR1 and PR2) function in both myoblasts and myotubes, whereas the third positive domain (PR3) and the sole negative domain (NR1) seem to function only in myotubes. PR1 contains a cluster of four CCAAT cis-elements, PR2 is a small 44-base pair region containing an SP1-like motif, and PR3 is a region previously shown to be recognized by both OXBOX- and REBOX-binding factors. By site-directed polymerase chain reaction linker mutations, the activity of the OXBOX/REBOX cis-element in myoblasts is shown to be masked by flanking sequences in PR3. The negative domain, NR1, is located between 300 and 1,000 base pairs upstream from the OXBOX/REBOX elements in a region containing multiple Alu repeats. Mobility gel shift analysis of DNA-protein complexes using competitor DNAs verified the involvement of both OXBOX- and REBOX-binding factors in PR3. Similar experiments show SP1-specific binding at PR2. These data with observations of OXBOX and REBOX-specific binding of an OXBOX/REBOX-like region within the conserved sequence block C of the human mitochondrial DNA D-loop sequence are consistent with the idea that OXBOX- and REBOX DNA-binding factors coordinate the expression of mitochondrial energy genes in highly oxidative tissues by working with well characterized general transcription factors such as SP1 and CCAAT DNA-binding proteins, which exist in the nucleus, and MTF, which exists in the mitochondrion.

Abstract
A significant number of patients complain of recurrent symptoms following lumbar spine surgery. The main differential diagnosis is between post-operative epidural fibrosis and recurrent disc protrusion. Computed tomography is generally preferred to myelography for making this distinction, not least by the patient. Intravenous contrast medium can further improve diagnostic specificity. This article reviews the practical aspects and diagnostic accuracy of computed tomography in failed back syndrome, and draws attention to the potential pitfalls and less common abnormalities which may be encountered.

Abstract
Seventy-eight excised specimens of squamous cell carcinoma of the vulva were reviewed retrospectively for the presence of lichen sclerosus or vulvar intraepithelial neoplasia (VIN) at sites proximal to the tumour or more distant. Lichen sclerosus was evident in 61% and VIN alone in 31%. VIN III (differentiated) was associated with over 50% of the specimens with lichen sclerosus. HPV 16 was found in six of the 11 VIN lesions, investigated but in none of the six with lichen sclerosus.

Abstract
Twelve patients with skin vasculitis complicating cystic fibrosis are described. Seven of these were proven histologically and of these two had systemic vascultitis. Staining of vasculitic tissue by the avidin-biotin immunoperoxidase technique using both monoclonal and polyclonal antisera directed against Haemophilus influenzae, staphylococcus aureus and Pseudomonas aeruginosa did not consistently reveal any bacterial antigens in these tissues. In one patient the vasculitis appeared secondary to ranitidine. There was no evidence of autoimmune disease in any of the patients. Antineutrophil cytoplasmic antibodies were detected in the serum of 40 per cent of the patients with vasculitis complicating cystic fibrosis but in none of 61 controls with cystic fibrosis (but without vasculitis) matched for age and sex and with similar bacteriological flora of sputum.
