Successful treatment of fusarium solani ecthyma gangrenosum in a patient affected by leukocyte adhesion deficiency type 1 with granulocytes transfusions

<p>Abstract</p> <p>Background</p> <p>Ecthyma gangrenosum (EG) manifests as a skin lesion affecting patients suffering extreme neutropenia and is commonly associated with <it>Pseudomonas aeruginosa </it>in immunocompromised patients. Leukocyte adhesion deficiency I (LAD I) which count among primary immunodeficiency syndromes of the innate immunity, is an autosomal recessive disorder characterized in its severe phenotype by a complete defect in CD18 expression on neutrophils, delayed cord separation, chronic skin ulcers mainly due to recurrent bacterial and fungal infections, leucocytosis with high numbers of circulating neutrophils and an accumulation of abnormally low number of neutrophils at sites of infection.</p> <p>Case Presentation</p> <p>We report at our knowledge the first case of a child affected by LAD-1, who experienced during her disease course a multi-bacterial and fungal EG lesion caused by <it>fusarium solani</it>. Despite targeted antibiotics and anti-fungi therapy, the lesion extended for as long as 18 months and only massive granulocytes pockets transfusions in association with G-CSF had the capacity to cure this lesion.</p> <p>Conclusion</p> <p>We propose that granulocytes pockets transfusions will be beneficial to heal EG especially in severely immunocompromised patients.</p

Compound-specific radiocarbon dating of the varved Holocene sedimentary record of Saanich Inlet, Canada

The definitive version was published in Paleoceanography 19 (2004): PA2012, doi:10.1029/2003PA000927.The radiocarbon contents of various biomarkers extracted from the varve-counted sediments of Saanich Inlet, Canada, were determined to assess their applicability for dating purposes. Calibrated ages obtained from the marine planktonic archaeal biomarker crenarchaeol compared favorably with varve-count ages. The same conclusion could be drawn for a more general archaeal biomarker (GDGT-0), although this biomarker proved to be less reliable due to its less-specific origin. The results also lend support to earlier indications that marine crenarchaeota use dissolved inorganic carbon (DIC) as their carbon source. The average reservoir age offset ΔR of 430 years, determined using the crenarchaeol radiocarbon ages, varied by ±110 years. This may be caused by natural variations in ocean-atmosphere mixing or upwelling at the NE Pacific coast but variability may also be due to an inconsistency in the marine calibration curve when used at sites with high reservoir ages.This work was supported by the Netherlands Organization for Scientific Research (NWO) and NSF grants OCE-9907129 and OCE-0137005 (Eglinton)

Effect of egg storage duration and brooding temperatures on chick growth, intestine morphology and nutrient transporters

WOS: 000411685000017PubMed ID: 28219464The effects of egg storage duration (ESD) and brooding temperature (BT) on BW, intestine development and nutrient transporters of broiler chicks were investigated. A total of 396 chicks obtained from eggs stored at 18 degrees C for 3 days (ESD3-18 degrees C) or at 14 degrees C for 14 days (ESD14-14 degrees C) before incubation were exposed to three BTs. Temperatures were initially set at 32 degrees C, 34 degrees C and 30 degrees C for control (BT-Cont), high (BT-High) and low (BT-Low) BTs, respectively. Brooding temperatures were decreased by 2 degrees C each at days 2, 7, 14 and 21. Body weight was measured at the day of hatch, 2, 7, 14, 21, 28 and 42. Cloacal temperatures of broilers were recorded from 1 to 14 days. Intestinal morphology and gene expression levels of H+-dependent peptide transporter (PepT1) and Na-dependent glucose (SGLT1) were evaluated on the day of hatch and 14. Cloacal temperatures of chicks were affected by BTs from days 1 to 8, being the lowest for BT-Low chicks. BT-High resulted in the heaviest BWs at 7 days, especially for ESD14-14 degrees C chicks. This result was consistent with longer villus and larger villus area of ESD14-14 degrees C chicks at BT-High conditions. From 14 days to slaughter age, BT had no effect on broiler weight. ESD3-18 degrees C chicks were heavier than ESD14-14 degrees C chicks up to 28 days. The PepT1 and SGLT1 expression levels were significantly higher in ESD3-18 degrees C chicks than ESD14-14 degrees C on the day of hatch. There was significant egg storage by BT interaction for PepT1 and SGLT1 transporters at day 14. ESD14-14 degrees C chicks had significantly higher expression of PepT1 and SGLT1 at BT-Low than those at BT-Cont. ESD14-14 degrees C chicks upregulated PepT1 gene expression 1.15 and 1.57-fold at BT-High and BT-Low, respectively, compared with BT-Cont, whereas PepT1 expression was downregulated 0.67 and 0.62-fold in ESD3-18 degrees C chicks at BT-High and BT-Low. These results indicated that pre-incubation egg storage conditions and BTs affected intestine morphology and PepT1 and SGLT1 nutrient transporters expression in broiler chicks.TUBITAKTurkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [112 0 220]This research was supported by TUBITAK (Project no: 112 0 220)

Squamous cell carcinoma of the penis: A clinicopathological study from a population with late circumcision

Squamous cell carcinoma (SCC) of the penis has been subject to only a few studies in populations where late childhood circumcision is performed. To asses clinicopathological features and human papillomavirus (HPV) status of penile SCC in men with late circumcision, eight institutions in the country volunteered to collaborate and 15 cases of penile SCC were collected from their pathology archives. The presence and genotype of HPV were determined in addition to clinicopathological features of the tumors. Findings were correlated with disease outcome. The mean age of the patients evaluated was 66.5 years. Histological subtypes were usual SCC (6/15), papillary (2/15), mixed (2/15), basaloid (2/15), acantholytic (1/15), pseudohyperplastic (1/15), and warty-basaloid (1/15) carcinomas. HPV was identified in 33.3% of samples; HPV16 was detected in 60% of positive cases and was associated with basaloid and/or warty morphology. Cause-specific 1-year and 2-year survivals were 76.9% and 54.5%, respectively. The usual subtype and nodal metastasis were associated with worse outcome (p=0.045 and p=0.047, respectively). As a conclusion, our results suggest an inclination for penile SCC to develop at a later age in a population with late circumcision than the patients from the regions of high penile cancer incidence. These men seem to have less frequent HPV association and their outcome appears poorer than other populations, although reaching substantial provision is not possible due to our limited case number. © 2019, Editura Academiei Romane.
