The use of indocyanine green fluorescence angiography to assess perfusion of chronic wounds undergoing hyperbaric oxygen therapy.

Objective: The purpose of this study is to determine the utility of using indocyanine green fluorescence angiography (IGFA) in assessing perfusion of chronic wounds after hyperbaric oxygen (HBO2) therapy.

Methods: From May 2016 to January 2018, 26 patients underwent both HBO2 and IGFA. A near-infrared charge-coupled camera measured the flow of intravenous indocyanine green into the wound.

Vogt-Koyanagi-Harada disease: presentation and implications in undocumented immigrants.

Vogt-Koyanagi-Harada syndrome is an autoimmune disease involving pigmented tissue in the eyes, auditory system, skin, and central nervous system. It often presents as bilateral chronic granulomatous panuveitis. We report the case of a 32-year-old immigrant who presented to the emergency department asking for a second opinion for loss of vision and progressive hearing loss.

Beliefs and attitudes towards participating in genetic research - a population based cross-sectional study.

Background: Biobanks have the potential to offer a venue for chronic disease biomarker discovery, which would allow for disease early detection and for identification of carriers of a certain predictor biomarker. To assess the general attitudes towards genetic research and participation in biobanks in the Long Island/Queens area of New York, and what factors would predict a positive view of such research, participants from the NSLIJ hospital system were surveyed.

Methods: Participants were recruited at six hospital centers in the NSLIJ system during the summers of 2009 and again in 2011 (n = 1,041).

Starving in the midst of plenty? A study of training needs for child and adolescent mental health service delivery in primary care.

Current UK child mental health policy seeks to engage primary care personnel in improving service delivery under the heading of 'Comprehensive CAMHS' but little is known about the size of this resource, the sufficiency of its training or its commitment to children's mental health. We surveyed local health, education and social services agencies within a UK Unitary Authority just outside London, using both questionnaire and focus group methodologies: 150 primary care personnel were identified in 14 teams. Of these 122 participated in the questionnaire survey, and 60 took part in focus groups.

Abdominal mucinous cystic neoplasm in a male child.

Mucinous cystic neoplasms (MCNs) make up a morphologic family of similar appearing tumors arising in the ovary and various extraovarian sites, including the pancreas, hepatobiliary tract, paratesticular soft tissues, and mesentery. Other than the uncommon mucinous cystadenoma of the ovary presenting in adolescence, MCNs are rarely seen by the pediatric pathologist. The present case is a 5-year-old boy with an abdominal mass appearing to arise in the mesentery of the small intestine.

Histoplasma phimosis: an uncommon presentation of a not uncommon pathogen.

Infection from Histoplasma capsulatum is usually subclinical, but it also can be disseminated in patients with a compromised immune status. Involvement of the external genitalia is a rare finding, occurring by direct contact or hematogenous spread. We present a case of histoplasma posthitis in a 71-year-old man, manifesting with the extremely unusual presentation of phimosis.

Absence of Mycobacterium avium subsp. paratuberculosis in the microdissected granulomas of Crohn's disease.

The etiology of Crohn's disease remains unknown with inflammatory, infectious, and/or genetic causes suspected. Granulomatous inflammation is a characteristic feature of the disorder, resembling the tissue response to mycobacterium. Mycobacterium avium subsp.

Loss of heterozygosity in the MXI1 gene is a frequent occurrence in melanoma.

Melanoma development and progression is thought to be the result of a multi-step accumulation of genetic damage, with loss of heterozygosity in chromosome 9p (MTS1) frequently described. In addition, chromosome 10q allelic loss has been reported, implicating the tumor suppressor gene PTEN/MMAC1 on 10q23.3.

Malignant blue nevus: a case report and molecular analysis.

Malignant blue nevus is a rare melanocytic tumor that is described by some authors as a variant of malignant melanoma, whereas others regard it as a distinct entity. To our knowledge no molecular studies of this tumor have been performed, although the molecular pathogenesis of conventional melanomas has been extensively described. We present a case of malignant blue nevus that developed in a 15-cm congenital blue nevus on the back of a 41-year-old man.

Widespread molecular alterations present in stage I non-small cell lung carcinoma fail to predict tumor recurrence.

Stage I non-small cell carcinoma (NSCLC) of the lung is typically treated with surgery alone, but with a 30 to 40% recurrence rate. Prognostic factors to stratify these patients into high- and low-risk groups would be of significant clinical value, but published data are conflicting. We studied 39 Stage I NSCLC treated with resection alone, followed for a minimum of 5 years, and divided into recurrent (RC) and non-recurrent (NRC) groups (n = 12 and 27, respectively).

Small-cell neuroendocrine carcinoma displays unique profiles of tumor-suppressor gene loss in relationship to the primary site of formation.

Small-cell neuroendocrine carcinoma (SCNC) is a well characterized malignancy with distinctive cellular morphology and aggressive biologic behavior most frequently encountered in the lung but also noted for origin from other sites. The basis for this difference in incidence and the impact of primary site location on the molecular pathogenesis of the neoplasm is not well understood. To address this issue and to identify reliable molecular markers of potential diagnostic value for primary site localization of this tumor, we have compared the genetic profile of cancer-related gene damage of SCNC arising from a variety of organ sites.

Correlation between dysplasia and mutations of six tumor suppressor genes in Barrett's esophagus.

Background: Barrett's esophagus (BE) may progress to adenocarcinoma through dysplastic progression. Classification of dysplasia in BE has significant interobserver variability. Our objective was to determine whether genetic alterations in BE correlate with degrees of histologic dysplasia.

Molecular genotyping of BK and JC viruses in human polyomavirus-associated interstitial nephritis after renal transplantation.

The human polyomaviruses BK virus (BKV) and JC virus (JCV) have been linked to ureteric stenosis and allograft interstitial nephritis, but molecular characterization of the species involved has not been performed. We studied paraffin-embedded renal tissue from 19 cases of allograft viral interstitial nephritis. Histological sections were subjected to polymerase chain reaction amplification using consensus, BKV-, and JCV-specific primers, with subsequent DNA sequencing for strain determination.

JC virus infection in allograft kidneys: analysis by polymerase chain reaction and immunohistochemistry.

Background: Polyoma virus nephropathy after transplantation is believed to be primarily due to the BK virus. We hypothesized that some cases may be associated with the JC polyoma virus (JCV), which is also known to be latent in the kidney.

Methods: We sought polymerase chain reaction evidence of JCV infection in needle biopsy specimens with and without viral nephropathy.

Leukemia cutis with prominent giant cell reaction.

We present a case of leukemia cutis associated with a prominent giant cell component. This lesion was initially diagnosed as chronic granulomatous inflammation 1 year before the definitive diagnosis of leukemia cutis was made. Skin biopsy specimens showed numerous Langhans-type giant cells occurring singly and as poorly formed granulomas.
