Abstract
SETTING Haiti has the highest burden of tuberculosis (TB) in the Americas, with an estimated prevalence of 254 per 100 000 population. The Haitian Group for the Study of Kaposi's Sarcoma and Opportunistic Infections (Groupe Haïtien d'Etude du Sarcome de Kaposi et des Infections Opportunistes, GHESKIO) conducted active case finding (ACF) for TB at the household level in nine slums in Port-au-Prince. OBJECTIVE We report on the prevalence of undiagnosed TB detected through GHESKIO's ACF campaign. DESIGN From 1 August 2014 to 31 July 2015, we conducted a retrospective cohort analysis using GHESKIO's ACF campaign data. All individuals who reported chronic cough (cough 2 weeks) were tested for TB at GHESKIO, and those aged 10 years were included in the analyses. RESULTS Of 104 097 individuals screened in the community, 5598 (5%) reported chronic cough and satisfied the study inclusion criteria. A total of 1110 (20%) were diagnosed with active TB disease (prevalence of 1066/100 000). Of the 5472 (98%) patients tested for human immunodeficiency virus (HIV), 528 (10%) were HIV-positive; 143 (3%) patients were diagnosed with both diseases. CONCLUSION Household-level screening for cough with TB and HIV testing for symptomatic patients was a high-yield strategy, leading to the detection of a prevalence of undiagnosed disease exceeding national estimates by more than four-fold for TB, and by five-fold for HIV.

Abstract
[18F]-3'-fluoro-3'-deoxythymidine (FLT) is a nucleoside-analog imaging agent for quantifying cellular proliferation that was first reported in 1998. It accumulates during the S-phase of the cell cycle through the action of cytosolic thymidine kinase, TK1. Since TK1 is primarily expressed in dividing cells, FLT uptake is essentially limited to dividing cells. Thus FLT is an effective measure of cell proliferation. FLT uptake has been shown to correlate with the more classic proliferation marker, the monoclonal antibody to Ki-67. Increased cellular proliferation is known to correlate with worse outcome in many cancers. However, the Ki-67 binding assay is performed on a sampled preparation, ex vivo, whereas FLT can be quantitatively measured in vivo using positron emission tomography (PET). FLT is an effective and quantitative marker of cell proliferation, and therefore a useful prognostic predictor in the setting of neoplastic disease. This review summarizes clinical studies from 2011 forward that used FLT-PET to assess tumor response to therapy. The paper focuses on our recommendations for a standardized clinical trial protocol and components of a report so multi center studies can be effectively conducted, and different studies can be compared. For example, since FLT is glucuronidated by the liver, and the metabolite is not transported into the cell, the plasma fraction of FLT can be significantly changed by treatment with particular drugs that deplete this enzyme, including some chemotherapy agents and pain medications. Therefore, the plasma level of metabolites should be measured to assure FLT uptake kinetics can be accurately calculated. This is important because the flux constant (KFLT) is a more accurate measure of proliferation and, by inference, a better discriminator of tumor recurrence than standardized uptake value (SUVFLT). This will allow FLT imaging to be a specific and clinically relevant prognostic predictor in the treatment of neoplastic disease.

Abstract
OBJECTIVES To determine the diagnostic accuracy of tests for the rapid diagnosis of bacterial food poisoning in clinical and public health practice and to estimate the cost-effectiveness of these assays in a hypothetical population in order to inform policy on the use of these tests. DATA SOURCES Studies evaluating diagnostic accuracy of rapid tests were retrieved using electronic databases and handsearching reference lists and key journals. Hospital laboratories and test manufacturers were contacted for cost data, and clinicians involved in the care of patients with food poisoning were invited to discuss the conclusions of this review using the nominal group technique. REVIEW METHODS A systematic review of the current medical literature on assays used for the rapid diagnosis of bacterial food poisoning was carried out. Specific organisms under review were Salmonella, Campylobacter, Escherichia coli O157, Staphylococcus aureus, Clostridium perfringens and Bacillus cereus. Data extraction was undertaken using standardised data extraction forms. Where a sufficient number of studies evaluating comparable tests were identified, meta-analysis was performed. A decision analytic model was developed, using effectiveness data from the review and cost data from hospitals and manufacturers, which contributed to an assessment of the cost-effectiveness of rapid tests in a hypothetical UK population. Finally, diagnostic accuracy and cost-effectiveness results were presented to a focus group of GPs, microbiologists and consultants in communicable disease control, to assess professional opinion on the use of rapid tests in the diagnosis of food poisoning. RESULTS Good test performance levels were observed with rapid test methods, especially for polymerase chain reaction (PCR) assays. The estimated levels of diagnostic accuracy using the area under the curve of the summary receiver operating characteristic curve was very high. Indeed, although traditional culture is the natural reference test to use for comparative statistical analysis, on many occasions the rapid test outperforms culture, detecting additional 'truly' positive cases of food-borne illness. The significance of these additional positives requires further investigation. Economic modelling suggests that adoption of rapid tests in combination with routine culture is unlikely to be cost-effective, however, as the cost of rapid technologies decreases; total replacement with rapid technologies may be feasible. CONCLUSIONS Despite the relatively poor quality of reporting of studies evaluating rapid detection methods, the reviewed evidence shows that PCR for Campylobacter, Salmonella and E. coli O157 is potentially very successful in identifying pathogens, possibly detecting more than the number currently reported using culture. Less is known about the benefits of testing for B. cereus, C. perfringens and S. aureus. Further investigation is needed on how clinical outcomes may be altered if test results are available more quickly and at a greater precision than in the current practice of bacterial culture.

Abstract
We characterized the histamine H(1) receptor agonism of various histaprodifen derivatives in guinea pig isolated ileum and trachea in comparison with histamine. Based on their affinity (calculated pK(A) values for ileum and trachea, respectively), the compounds were ranked as follows: suprahistaprodifen (8.31/8.08) > N(alpha)-(4-phenylbutyl)histaprodifen (7.22/5.93) >or= histamine (5.79/5.19) approximately methylhistaprodifen (5.57/6.07). Based on their efficacy (calculated tau values for ileum and trachea, respectively), the compounds were ranked as follows: methylhistaprodifen (37.67/2.50) > histamine (5.64/1.80) > suprahistaprodifen (1.63/1.42) >or= N(alpha)-(4-phenylbutyl)histaprodifen (0.083/1.54). In the ileum, histamine and methylhistaprodifen showed a high histamine H(1) receptor reserve while suprahistaprodifen and N(alpha)-(4-phenylbutyl)histaprodifen are devoid of any histamine H(1 )receptor reserve. On the trachea, no histamine H(1 )receptor reserve was demonstrable with the four tested agonists. The kinetic of contraction/relaxation of the ileum was faster with histamine and methylhistaprodifen than with suprahistaprodifen and N(alpha)-(4-phenylbutyl)histaprodifen. Histamine contracted the trachea faster than histaprodifen derivatives. Levocetirizine antagonized contractions induced by histamine and histaprodifen derivatives in both tissues. The differences observed in the calculated pA(2) (7.60-8.29) and/or pD'(2) values (6.28-7.90) depending on the tissue and/or the agonist are discussed.

Abstract
With rising numbers of single-parent families, a phenomenon becoming increasingly prevalent is the child orphaned by cancer. We sought to examine issues related to custody planning addressed prior to the patient's death. Ten deceased patients with minor children were identified. The contact person was administered a brief questionnaire regarding the minor children and custody issues. The study involved twenty children, ages ranging from 3-20, mean age 9.8. Only five of the ten families developed custody plans that were ultimately successful. One-half of the families reported the patient had suffered with this issue and almost one-half of the children were not aware of the custody plans that had been arranged for them. In 40% of the cases, the children ultimately went to people to whom the deceased parents were opposed. It is our belief that if we can improve these statistics, we might improve the quality of life of these families.

Abstract
Twenty patients with burn injuries were randomly assigned to a massage therapy or a standard treatment control group during the remodeling phase of wound healing. The massage therapy group received a 30-minute massage with cocoa butter to a closed, moderate-sized scar tissue area twice a week for 5 weeks. The massage therapy group reported reduced itching, pain, and anxiety and improved mood immediately after the first and last therapy sessions, and their ratings on these measures improved from the first day to the last day of the study.

Abstract
Twenty-eight adult patients with burns were randomly assigned before debridement to either a massage therapy group or a standard treatment control group. State anxiety and cortisol levels decreased, and behavior ratings of state, activity, vocalizations, and anxiety improved after the massage therapy sessions on the first and last days of treatment. Longer-term effects were also significantly better for the massage therapy group including decreases in depression and anger, and decreased pain on the McGill Pain Questionnaire, Present Pain Intensity scale, and Visual Analogue Scale. Although the underlying mechanisms are not known, these data suggest that debridement sessions were less painful after the massage therapy sessions due to a reduction in anxiety, and that the clinical course was probably enhanced as the result of a reduction in pain, anger, and depression.

Abstract
We report here a case of fibrillary glomerulonephritis arising in a 43-year-old man with a polyclonal gammopathy, who presented with progressive renal insufficiency, microscopic hematuria, and mild proteinuria (0.7 g/d). Ultrastructural studies showed deposits of randomly oriented fibrils in the glomerular mesangium and adjacent portions of some glomerular basement membranes, with a mean fibril thickness of 14.3 nm, highly consistent with fibrillary glomerulonephritis. The Congo red stain was negative on histologic sections. Immunofluorescence studies revealed strong mesangial and focal glomerular capillary staining for immunoglobulin (Ig) G, complement (C) 3, and kappa light chains, with minimal staining for IgA, IgM, C1q, or lambda light chains. The IgG present was entirely of the IgG1 subclass. This case is quite unusual for fibrillary glomerulonephritis, which typically presents with polyclonal IgG deposits and IgG4 as the dominant IgG subclass present. Monoclonal deposits are more frequently associated with immunotactoid glomerulopathy, characterized ultrastructurally by microtubule-like structures 30 to 50 nmn thick, often in parallel arrays. The present case illustrates that although fibrillary glomerulonephritis and immunotactoid glomerulopathy might be distinguishable on ultrastructural grounds, there is overlap between these two entities with respect to the potential composition of the glomerular deposits present.

Abstract
The safety, efficacy, and outcome of long-term patient-triggered synchronized assisted ventilation in infants (SAVI) was studied in very low birthweight infants (450 to 1250 g) with uncomplicated respiratory failure. Synchronization was accomplished by modified thoracic impedance technology using standard neonatal cardiorespiratory monitors with the output of the ventilation synchronizer triggering the exhalation solenoid of a standard neonatal respirator. In this nonrandomized study, the technique was found to be safe and reliable without any episodes of technical failure or adverse effects. The results indicated that in comparison with infants receiving conventional ventilation, infants receiving SAVI required (1) shorter duration of ventilation, (2) decreased duration of oxygen therapy, and (3) decreased progression of intraventricular hemorrhage to greater than or equal to grade III. Decreased duration of ventilation was statistically significant in infants weighing less than 850 g (P less than .02). These beneficial trends were ratified during a 3-year period in a total of 110 cases.

Abstract
In a retrospective review of 301 newly diagnosed tumours of the colon and rectum, 61 patients (20%) presented with liver metastases. The mean survival for this group was 7.4 months. Five patients with solitary metastases were found who may have been helped by further surgery. There was a 20% operative mortality. No significant association between the grade, differentiation, lymph node status or venous invasion of the primary lesion was demonstrated. Operative palliative resection of the primary lesion did not improve survival. These results confirm the poor prognosis for patients with liver metastases, justifying all efforts into the earlier detection and prevention of colorectal carcinoma.

Abstract
To further define the pathophysiology of the syndrome of acquired isolated hypoaldosteronism, we determined plasma concentrations of active and inactive renin and urinary kallikrein and prostaglandin E2 excretion rates in 11 patients with the syndrome, 12 patients with similar serum creatinine levels, but without hyperkalemia, and in 12 normotensive patients with normal renal function and low plasma renin activities (PRA). Ten of 11 patients with the syndrome had low baseline PRA, and, unlike the control groups, six of 11 failed to double their PRA after furosemide stimulation. There were also consistent abnormalities in the percentage of inactive renin, no patient having a value less than and no control subjects having a value greater than 65%. Seven of 11 patients had prostaglandin E2 excretion rates lower than either control groups. Urinary kallikrein excretion rates in the patients with isolated hypoaldosteronism were significantly lower than in the control groups, but increased in response to therapy with fludrocortisone.

Abstract
An experimental autoimmune model was used to study effects of nerve growth factor deprivation on the peptide content of sensory neurones and on pain sensitivity. Rats exposed during development to anti-nerve growth factor antibodies showed an increased threshold towards nociceptive stimuli. These animals also showed a significant decrease in substance P levels in their dorsal root ganglia and spinal cord. These results suggest that substance P-containing primary sensory neurones are involved in certain types of nociception.
