Published: June 2023

ABSTRACT
               Duku (Lansium domesticum) has become the flagship fruit of Jambi and is widely planted and becomes a source of income for farmers. In the last 5 years, around 310,828 trees have been damaged, that is, they die and die. In natural conditions, duku jambi plants are often flooded. Thus, conditions of hypoxia or anoxia are often experienced by the root system of plants. This limited O2 condition can affect the growing environment of the duku plant which in turn will affect the growth, development, and survival of the plant due to a decrease in energy. The method used is a field survey and takes environmental and soil data. Observations of duku plants and other vegetation include: the number of clumps, the number of duku individuals according to the growth phase, the type of vegetation, the number of individual species found in each sample unit, and the coverage area. . Based on the results obtained, it can be seen that the highest density is found in the Kelopak Alai area with the highest density value being the duku tree of 325, and the highest frequency is found in the area of ​​the Karang City area with the highest frequency value being the duku tree of 87.50, while for dominance The highest value is found in the village of Olak Rambahan with the highest dominance value is the duku tree of 3300,955.

Published: June 2023

Utilization of composite boards for furniture has been widely used in order to substitute solid wood. Coating veneer (veneering) is a technique to improve the appearance of composite panel products, such as plywood. This research was conducted to determine the effect of the type of veneer and the mass of adhesive lath on the physical and mechanical properties of veneering plywood. The veneer used are from teak, mahogany and mindi. The adhesive used was polyvinyl acetate (PVAc) with a melting weight of 130 g/m2, 150 g/m2, 170 g/m2. The results showed that the type of veneer had no effect on the physical and mechanical properties of the composite board. The physical properties in the form of density are affected by the weight of the adhesive, the higher the amount of adhesive, the higher the density. Veneer delamination with glue spread of 150 and 170 g/m2 complies with JAS Type 2 standards. Veneer composite products with PVAc adhesives can be used in interior areas where there is frequent short term exposure to water.

The Great Pasha, Buried Alive: The Archetypes of the Characters in Truman Capote’s Story “A Tree of Night”
Authors: Zakharov Denis V.
Published: June 2023

“A Tree of Night” is probably Truman Capote’s most terrifying piece, which, along with “Miriam”, has become his signature story. Created in 1943 and published two years later in Harper's Bazaar, this story was called a “pure distillate of terror” by reviewers. Despite the absence of the manuscript in Capote’s archive and his silence about how and when this story was written, the paper pieces together the writer’s personal circumstances during that period. Based on these data the paper makes a suggestion on when the story might have been created and identifies the archetype of the mysterious character named the Great Pasha. This information corrects a number of inaccuracies contained in Capote’s biography published by Gerald Clarke in 1988. The paper explores in detail the history of the Great Pasha — “a fakir from Egypt”, who toured American South with a bold performance “Buried Alive”. According to the hypothesis made in the article, it was the Great Pasha who met six year old Truman at his aunts’ house in Monroeville in May 1931. Twelve years later Capote drew on his memories of the Great Pasha and his assistant Madame Flozelle to create sinister characters of his Gothic story “A Tree of Night”. Thanks to the archival materials the paper managed to bring out the traits that Capote’s characters owe to their archetypes, and to reconstruct the facts of the fakir’s life. For the first time in Russia the article reproduces a unique picture featuring the Great Pasha, his assistant, and the writer’s mother Lillie Mae Faulk.

O presente artigo tem por finalidade analisar e demonstrar a forma pela qual são exercidos os controles interno e externo nos processos licitatórios. Com efeito, vislumbra-se a atuação da Comissão de Licitações, que não deve ficar restrita apenas ao controle da legalidade da discricionariedade, mas necessita prender-se também a uma verificação de conformidade das ações discricionárias com os preceitos emanados pela legislação vigente. Os questionamentos sobre a possibilidade da discricionariedade administrativa vir a ser invocada na tomada de decisões nos certames licitatórios serão aqui abordados, trazendo-se como exemplo, o procedimento adotado na Universidade Estadual do Sudoeste da Bahia (UESB). Neste mister, partir-se-á da análise do Sistema Principiológico no Estado Democrático de Direito que rege a Administração Pública, especificamente os processos licitatórios, para, posteriormente, serem tecidas considerações acerca dos atos administrativos, da discricionariedade e de como se dão os controles interno e externo nos processos licitatórios.
Atuação do Núcleo Maria da Penha (NUMAPE) de Irati-PR no contexto pandêmico
Authors: Santos Kátia Alexsandra dos , Gonçalves Gabriela Walter
Published: June 2023

Este trabalho visa discutir a atuação do projeto de extensão Núcleo Maria da Penha (NUMAPE) no município de Irati-PR, durante a pandemia de Covid-19. O projeto é composto por equipe interdisciplinar das áreas da psicologia e direito e realiza atendimentos psicológicos e jurídicos a mulheres em situação de violência. A metodologia utilizada para este trabalho foi o relato de experiência. Em março de 2020, com as determinações acerca do isolamento social, foi necessária a suspensão das atividades presenciais e, a partir de então, iniciaram-se as atividades em caráter remoto, que evidenciaram as dificuldades de acesso à tecnologia necessária para esse formato pelas usuárias do projeto. Os dados do projeto indicam queda nos atendimentos psicológicos e manutenção nos atendimentos jurídicos, devido à necessidade de aspectos materiais possibilitados por ações jurídicas. No contexto pandêmico, além dos desafios já encontrados no cotidiano de trabalho, como o direcionamento ao projeto de outras demandas da rede municipal, também nos deparamos com as dificuldades e necessidade de adaptação decorrentes da pandemia. Observamos, ainda, comprometimento do trabalho interdisciplinar e intersetorial pelo afastamento social. Finalizamos articulando a experiência durante o período pandêmico com a atuação do núcleo desde sua implementação, discutindo acerca da função que ocupou/ocupa na rede de enfrentamento e atendimento às mulheres em situação de violência e fazendo considerações acerca do histórico de constante e crescente precarização.

Successful surgical management of a single coronary artery with giant coronary artery aneurysm with fistula to the right ventricle
Authors: Liao Shu-Sheng , Chen Mei , Wang Jue , Ye Teng , Liu Jinjin
Published: June 2023

A giant coronary artery aneurysm (GCAA) concurrent with coronary artery
fistula is a rare condition, and it becomes even more unusual when
combined with a single coronary artery (SCA) anomaly. Here we report
such an extremely rare case, who is a 35-year-old woman presenting with
severe chest distress. A GCAA with fistula to the right ventricle was
noted, occurring in a single coronary artery, diagnosed by multimodality
cardiovascular imaging techniques. Both GCAA and coronary artery fistula
can cause severe cardiac complications, which jeopardize life. While an
SCA is mostly asymptomatic, it may also lead to sudden cardiac death as
well. Therefore, surgical intervention was recommended. We chose a novel
thrombus-inducing strategy to eliminate the GCAA and repair the fistula.
Symptoms were relieved after the surgery, and the patient remained
asymptomatic over 8 months of follow-up.

Authors: Murali Akshaya , Rengaraj Sasirekha , PS Priyamvada , Sivanandan Sindhu , R Karthik Udayakumar
Published: June 2023

Objective: To study the adverse maternal and perinatal outcomes
in women with severe features of preeclampsia among different ranges of
proteinuria. Design: Prospective Cohort Study.
Setting: Department of Obstetrics and Gynaecology, Jawaharlal
Institute of Post-graduate Medical Education and Research (JIPMER),
Puducherry, India. Population: 202 singleton women with severe
features of preeclampsia. Methods: Women satisfying the
inclusion criteria were managed based on department protocol, assessed
based on delivery outcomes, adverse maternal and perinatal outcomes.
These women were followed up till 12 weeks postpartum. Main
Outcome Measures: Composite adverse maternal and perinatal outcomes
were recorded using ROC curves. Sensitivity, specificity, positive and
negative predictive values of proteinuria were used in predicting
adverse outcomes. Results: There was a significant association
between the values of antepartum 24-proteinuria and urine PCR
(p<0.001). There were 33 stillbirths (16.34%) and 19 neonatal
deaths (11.24%). 24-hour proteinuria was found to have a significant
correlation with composite adverse perinatal outcome (p=0.002) and
individual outcomes of NICU admission for >48 hours
(p=0.01) and neonatal sepsis (p=0.02) but not adverse maternal outcomes
(p=0.998). The optimum cut-off adverse neonatal outcomes was 905 mg
proteinuria/day (sensitivity-74.2%; specificity-51%). 15% of the
women had a persistently elevated urine PCR at 3 months postpartum.
Conclusion: In women with severe features of preeclampsia,
severe and massive proteinuria were related to composite adverse
perinatal outcome, but not composite adverse maternal outcome. 24-hour
urine protein, but not Urine PCR was significantly associated with
persistent proteinuria. The women with persistent postpartum proteinuria
(15%) require long term follow up to assess the development of chronic
renal diseases. Funding: No external funding was utilized for
this study. Keywords: hypertension, preeclampsia; proteinuria

Maternal haemoglobin drop in multiple pregnancy is associated with increased gestational age at delivery and birthweight: A retrospective study
Authors: Savvidou Makrina , Townsend Kristin , Maric Tanya , Steer Philip
Published: June 2023

Objective: To investigate the hypothesis that maternal
haemoglobin (Hb) levels in twin pregnancy fall between the first and
second trimesters, and that the size of the fall is associated with
gestational age at birth and birthweight (BW). Design:
Retrospective study. Setting: Inner London Maternity Unit.
Population: Pregnant women with twin pregnancies delivering two
live, phenotypically normal neonates, after 24
weeks of gestation, between October 2009 and September 2021.
Methods: Measurement of Hb, at ≤14 weeks
of gestation, (Hb1) and again at 20 -30
weeks gestation (Hb2). Hb drop was defined as
Hb1-Hb2. Small for gestational age was defined as BW <10th
percentile for gestation. The association of Hb drop with gestational
age at birth, BW, SGA and intertwin BW discrepancy of ˃25%, was
evaluated. Main outcome Measures: Gestational age at birth
, incidence of SGA neonates and/or intertwin BW discrepancy
>25%. Results: 925 women with twin pregnancies.
Maternal Hb1 did not correlate with gestational age or SGA or twins with
BW discrepancy >25%. However, a larger Hb drop was
associated with a higher gestational age at birth (p<0.001), a
larger BW of both twin 1 and 2 (p<0.001) and a trend towards
reduction in the incidence of delivering one or two SGA neonates
(p=0.005 and p=0.003, respectively) or twins with BW discrepancy of
>25% (p=0.005). Conclusions: The study has shown
that a larger maternal Hb drop from the first to the second trimester is
associated with a higher gestational age at birth, a larger BW and
smaller BW discrepancy in twin pregnancies.
Sorghum Oleoresins: Effect of Extraction on Compositional and Structural Characteristics
Authors: Kaya Eda , Yucel Umut , Peiris Shanta , Aramouni Fadi
Published: June 2023

Oleoresins are resin-like viscous materials obtained from plants,
oilseed, or spices with functional properties. The extraction process
determines their stability, composition, and physicochemical properties.
Oleoresins were obtained from ground waxy burgundy whole grain sorghum
with and without ball milling by using the following solvents: two types
of novel ionic liquids (IL1: 1-n-Hexyl-3-methylimidazoliumchloride, IL2:
1-Ethyl-3-methylimidazoliumchloride), ethanol and dichloromethane. The
effects of processing were evaluated for the extraction yield, protein,
fat and total phenolic content, fatty acid composition, particle size
and zeta potential, and FTIR spectra. The use of ILs and ball mill
process significantly (P < 0.05) affected the extraction yield
and physicochemical properties. The highest extraction yields increased
(31.35% ± 0.58) when ball milling used with IL2 in comparison to the
lowest (18.37% ± 0.77) obtained by traditional ethanol extraction. In a
similar way, protein concentration and phenolic content were the highest
(1.37% ± 0.05 and 0.57% ± 0.01, respectively) with ball milling
extraction and IL1. The FTIR spectra indicated higher phospholipids (at
1200 cm-1) and protein-phospholipid bonding (at 1700 cm-1) by ILs, and
ball milling as compared to traditional extraction. Overall, wet
milling-assisted extraction by using ball mill and ILs can provide
control for the composition of the oleoresins important for their
functional properties with higher extraction efficiencies as compared to
traditional techniques.

Published: June 2023

In this study, a ZnCo2O4/Ag3PO4 composite catalyst was prepared by the
precipitation method, and its photocatalytic degradation activity for
methyl orange (MO) was studied. The catalysts were characterized by TEM,
XRD, EDX, HRTEM, SAED, SEM, XPS, and UV-Vis-DRS. The results indicate
that 0.1 ZnCo2O4/Ag3PO4 The composite system has a good photocatalytic
degradation effect on methyl orange. Under 30-minute simulated sunlight
conditions, the degradation rate can reach 94%. The results show that
the maximum reaction rate constant of 0.1 ZnCo2O4/Ag3PO4 is 0.05301
min-1, which is three times the size of pure Ag3PO4 and 52 times the
size of pure ZnCo2O4. After three cycles, 0.1 ZnCo2O4/Ag3PO4 still
degraded methyl orange (MO) at a rate of 84.4%. The trapping experiment
showed that hole (h+) and O2- played the most important roles in the
photocatalytic degradation field of methyl orange (MO) by 0.1
ZnCo2O4/Ag3PO4, and hydroxyl radical (OH·) played a partial role. The
energy level structure of ZnCo2O4/Ag3PO4 is conducive to the effective
separation of photogenerated electrons and holes, improving the lifespan
of photogenerated charges. Among them, the photocatalytic performance of
0.1 ZnCo2O4/Ag3PO4 is the most excellent.
Cutaneous necrosis associated with recombinant interferon injection. Report of three cases with interferon beta-1b and review of the literature.
Authors: Weinberg JM , Wolfe JT , Sood S , Saruk M , Rook AH , Spiers EM.
Published: June 2023

Interferons are cytokines produced by cells in response to stimulation by certain antigens and infectious agents. In recent years, recombinant interferons have been developed, which have antiviral, antiproliferative, and immunomodulatory functions. Several cutaneous reactions have been reported, including cutaneous ulceration at injection sites. We now report three cases of cutaneous ulceration caused by interferon beta-1b injections. In addition, we review all of the previously reported cases of cutaneous ulceration caused by recombinant interferons and discuss the different mechanisms by which these substances may produce this effect.
Percutaneous absorption of organic solvents during intermittent exposure in guinea pigs.
Authors: Boman A , Hagelthorn G , Magnusson K
Published: June 2023

Skin absorption under intermittent exposure of guinea pigs to n-butanol, toluene, 1,1,1-trichloroethane was studied. Groups of guinea pigs were exposed to test organic solvents for 1 min at 30-min intervals during 4 h, in all 8 exposures. Skin absorption of solvent was assessed by following the concentration of solvent in the blood. This intermittent exposure was compared to continuous exposure over 4 h. Absorption of toluene and 1,1,1-trichloroethane was low, but a considerable amount of butanol was absorbed through the skin on intermittent exposure. A typical serrated absorption profile was seen for butanol that was less pronounced for toluene and 1,1,1-trichloroethane. The absorption of butanol was highest at the end of the exposure period. The differences in absorption profiles may be due to the differences in vapour pressure in the solvents in association with the animal method used. The amount absorbed varied inversely with vapour pressure. Hair stubble may act as a trap for solvents with low vapour pressure. Adequate ventilation reduces unoccluded skin absorption of volatile organic solvents.
Life expectancy, mortality and prognostic factors in neurofibromatosis type 1. A twelve-year follow-up of an epidemiological study in Göteborg, Sweden.
Authors: Zöller M , Rembeck B , Akesson H O , Angervall L
Published: June 2023

Neurofibromatosis type 1 (NF1) is a genetic disease with an extremely wide range of manifestations. As yet, the individual course of NF1 cannot be predicted, and it is uncertain to what extent the disorder is associated with increased mortality. In order to gain insights into these aspects, we have conducted a 12-year follow-up study of 70 adult NF1 patients in the city of Göteborg, Sweden, whereby life expectancy, mortality, causes of death and the prognostic value of clinical findings were investigated. Clinical examinations were made, and all available records, including medical files, death certificates, and autopsy reports were scrutinized. The survival in the NF1 cohort was compared to that in the general Swedish population. Twenty-two deaths occurred in the NF1 group, whereas 5.1 deaths were expected in the general Swedish population (p = < 0.001). The mean age at death was 61.6 years. Malignancy was found in 12 (55%) of the deceased (soft tissue sarcomas in 3, and carcinomas in 9). Severe complications related to NF1 were seen in 27%. Hypertension was significantly associated with increased mortality, as 10 out of 12 (83%) patients with hypertension died during the observation period. NF1 was associated with increased mortality due to malignancy and NF1-related complications.

To investigate the inflammatory and immunological aspects of severe acne, we examined the luminol-enhanced chemiluminescence of whole blood, T-cell subsets and natural killer cell functions in 11 patients with severe nodular acne and 4 patients with acne fulminans. In patients with severe nodular acne, the active phase of the disease, compared to the values in remission (means 47 mV, SD 24.8 and 32 mV, SD 8.3, p < 0.05). The patients with acne fulminans also showed high values in the active phase of the disease (mean mV 68.3, SD3.5) compared to remission (mean 30.5 mV, SD 15.3). No marked alterations were seen in the percentages of T-helper cells, T-suppressor cells or DR-positive lymphocytes or in the levels of soluble interleukin 2 receptor. The percentages and activities of natural killer cells did not show any significant changes either. Five patients (4 with severe nodular acne and one with acne fulminans, accounting for 33% of all patients) carried HLA Cw6 antigen, which is a significantly increased frequency compared to health controls (pc = 0.015). The present chemiluminescence results suggest that peripheral blood neutrophils are activated in patients with severe acne.

Published: June 2023

Basaloid proliferations of epidermis overlying dermatofibromas and morphologically resembling superficial basal cell carcinomas might possess a malignant potential. In order to elucidate whether these basaloid proliferations share phenotypic characteristics with malignancy, we examined immunohistochemically 19 cases of dermatofibroma with overlying epidermal basaloid proliferations, 10 dermatofibromas with overlying simple epidermal proliferations, and 10 invasive basal cell carcinomas for expression of p53. Simple and basaloid proliferations showed sparse positive immunostaining for p53, as seen in normal epidermis. No differences in staining pattern or number of positive keratinocytes could be demonstrated between these conditions. The dermatofibromas were negative. The invasive basal cell carcinomas showed abundant p53 positivity. The lack of p53 immunoreactivity in the epidermal basaloid proliferations overlying dermatofibromas indicates that these lesions have not acquired a phenotype as seen in malignant conditions.

Published: June 2023

Zinc therapies exert beneficial effects in several cutaneous pathologies through their antiinflammatory properties, but target cells and mechanisms of action are still uncertain. We wondered whether markers of the keratinocyte activation state, such as the expression of immune surface antigens (ICAM-1 and HLA-DR) and the production of TNF-alpha, frequently detected in inflammatory reactions, may be reduced by zinc. For this purpose, we used normal human keratinocytes derived from plastic skin surgery and cultured in low-calcium medium (MCDB153). We studied the effects of ZnSO4 (12.5 to 50 microM) alone or in combination with IFN-gamma (5 U/ml), a mediator of inflammation produced by activated T-cells, or nickel (5-10 micrograms/ml), a sensitizing metal hapten. Using FACS analysis, we showed that the combination of zinc with nickel or the addition of ZnSO4 24 h before IFN-gamma or NiSO4 treatments reduced ICAM-1 expression on the keratinocyte surface (p < 0.01). However, zinc did not modify the IFN-gamma induced expression of HLA class II antigen on keratinocytes. Zn2+ could also reduce the TNF-alpha secretion of keratinocytes stimulated by IFN-gamma or Ni2+ during 48 h. Taken together, these data indicate that zinc can directly reduce some keratinocyte activation markers frequently observed in vivo
Photoirritation: a new photobiologic phenomenon induced by long wavelength UVA radiation in hairless mice treated with broad-spectrum sunscreens.
Authors: Kligman L H , Zheng P , Kligman A M
Published: June 2023

While assessing the protective effect of broad-spectrum sunscreens against chronic UVA radiation, we observed a paradoxical worsening of skin damage with one product. To further examine this finding, five proprietory broad-spectrum sunscreens were applied to albino hairless mice irradiated thrice weekly for 32 weeks with a UVASUN lamp (> 340 nm). Appropriate age-matched controls were included. After approximately 12 weeks, two sunscreens induced a marked dermatitis. Biopsies showed damage greatly exceeding that found in UVA-irradiated, unprotected controls. Histologically, elastic fibers were hyperplastic, coalescing into elastotic clumps. Glycosaminoglycans also increased. Collagen damage was notable since UVA alone does not induce a histologic change. Electron microscopy confirmed these findings. Two other sunscreens provided nearly complete protection. Against chronic UVB radiation, the two UVA photoirritating sunscreens provided substantial protection. Since the UVA sunfilter, oxybenzone, was the same in all sunscreens, we postulate that an irritating component of the vehicle was responsible for the UVA-induced photoirritation. The fifth sunscreen produced severe damage with UVB and UVA.

Cryoglobulinemia has an unknown etiology in many cases. In the last years, hepatitis C virus has been known to be involved as a causative agent of so called essential mixed cryoglobulinemia. We report 8 patients suffering from cutaneous vasculitis and chronic hepatitis C virus infection. Their sera showed cryoglobulinemia (6 cases mixed, 2 cases not typified), rheumatoid factor and complement consume. Their hepatitis C virus infection was confirmed by PCR. Hepatitis C virus RNA was found by PCR in 6/6 cryoprecipitates and 5/6 supernatants. The patients were followed for 0.5-12 years. Three of them developed renal affection (2 membranoproliferative glomerulonephritis, 1 not biopsied). Two patients were treated with alpha interferon. One patient noted a marked improvement in her cutaneous vasculitis with interferon treatment, lasting for 18 months after the end of treatment. We recommend the search of hepatitis C virus infection in every case of mixed cryoglobulinemia. Interferon therapy may be useful in some of these cases.

Published: June 2023

The aim of the present study was to confirm the increase of adenosine deaminase (ADA) activity in progressive systemic sclerosis (PSS), described by Sasaki & Nakajima, and to compare plasma ADA activity of patients in different stages of the disease. Enzyme activity was measured with a colorimetric assay. The 48 patients were subdivided into 3 groups: subgroup 1 (n = 10), disease still limited to the skin subgroup 2 (n = 21), involvement of the skin and oesophagus and subgroup 3 (n= 17), involvement of the skin and multiple internal organs. ADA levels were highest in subgroup 3. However, the difference with respect to subgroup 2 did not reach statistical significance. Subgroup 1 was different from controls and subgroups 2 and 3 (p
Human in vivo cutaneous microdialysis: estimation of histamine release in cold urticaria.
Authors: Andersson T , Wårdell K , Anderson C
Published: June 2023

A novel bioanalytical in vivo sampling technique, cutaneous microdialysis, was used to follow the chronology of skin histamine release in 3 patients with cold urticaria and in 2 healthy volunteers. Laser Doppler perfusion imaging was used simultaneously to monitor the skin circulatory response. Microdialysis samples were collected at 10-min intervals and analysed by radioimmunoassay technique. Fifty minutes after probe insertion, the ventral forearm skin in the area of the dialysis membrane was provoked for 5-15 min with a 25 x 40 mm ice cube covered with plastic foil. In the cold urticaria patients, an up to 80-fold increase of histamine was observed, with peak levels 20-30 min after challenge. Histamine levels then fell to reach "baseline" levels within 50 min. In the healthy subjects, the histamine increase was earlier, less pronounced and of shorter duration. Cutaneous microdialysis and laser Doppler imaging offer new possibilities for the chronological multiparameter assessment of inflammatory skin disorders in vivo.
Acetylcholine induces different cutaneous sensations in atopic and non-atopic subjects.

Published: June 2023

The mediators eliciting pruritus in atopic eczema are a matter of discussion, since several substances may be involved and histamine is unlikely to be the main agent. Hence, in this study we examined the cutaneous sensations and vascular reactions in 15 patients with atopic eczema and in 15 non-atopic subjects after i.c. injection of acetylcholine (Ach, 0,5 M, 20 microliter) or buffered saline, respectively. The sensory perceptions were rated by a visual analogue scale (VAS) as to quality and intensity, and the vascular reactions were monitored by laser Doppler flowmetry and evaluated planimetrically as to flare and wheal extension. The flares and wheals in both groups were similar
The guinea pig maximization test--with a multiple dose design.
Authors: Andersen K E , Vølund A , Frankild S
Published: June 2023

The guinea pig maximization test (GPMT) is usually performed with one moderately irritant induction dose of the allergen and gives a qualitative assessment-hazard identification-of the allergenicity of the chemical. We refined the GPMT by applying a multiple dose design and used 30 guinea pigs in a test divided into a control group and 5 test groups of 5 animals. Each group was treated with different induction concentrations of the allergens: formaldehyde, cinnamic aldehyde, propyl paraben, lidocaine, mercaptobenzothiazole or chlormethylisothiazolinone/methylisothiazolinone. The test results were analysed using a logistic multidose response model. The precision of the results depends only on the total number of animals, the dose design and the response pattern. The maximal sensitization rate for a chemical was determined, and the intracutaneous induction concentration that sensitized 50% of the animals (EC50) (or another percentage) was estimated. Further studies are needed to prove the validity of this idea. However, improvements in protocols for the GPMT are needed to reduce interlaboratory variability in results and to reduce the number of animals used for allergenicity tests.

Setleis' syndrome is an uncommon inherited condition characterized by bilateral "scarlike" depressions on the temples and a wide spectrum of associated facial abnormalities. We report on a typically affected Japanese boy, whose mother and grandfather show a much milder expression of this disorder, suggesting an apparent autosomal dominant inheritance.
Epidermal regeneration and occlusion.
Authors: Van de Kerkhof PC , De Mare S , Arnold WP , Van Erp PE
Published: June 2023

Disruption of the stratum corneum, by tape stripping or chemical injury, results in epidermal recovery of the skin barrier. In human skin, 40-48 h after surface trauma, epidermal proliferation is maximal. In a previous study in mice, occlusion with plastic or the hydrocolloid Duoderm proved to inhibit the regenerative response. The aim of the present investigation was to find out whether occlusion modulates epidermal proliferation following removal of the stratum corneum in normal healthy volunteers by sellotape stripping. Epidermal proliferation was assessed, using a multiparameter approach, by measuring ornithine decarboxylase activity, keratin 16 expression and DNA synthesis. Following tape stripping without subsequent occlusion, ornithine decarboxylase activity, keratin 16 expression and DNA synthesis were induced to the same extent as observed in previous studies. However, in contrast to the experiments in mice, no indication of a modulation of these responses was observed by the application of the hydrocolloids Duoderm and Comfeel. In human skin, a direct effect of the artificial restoration of the skin barrier on epidermal regeneration remains unsubstantiated.
Photosensitivity dermatitis/actinic reticuloid syndrome in an Irish population: a review and some unusual features.
Authors: Healy E , Rogers S
Published: June 2023

Nine patients with photosensitivity dermatitis and actinic reticuloid syndrome are reported. The rash affected light-exposed skin only in 7 patients and extended to covered sites in 2. Seven were sensitive to UVB, UVA and visible light, one to UVA and one to visible light only. Two patients had significant clinical improvement in spite of both having suffered severe disease previously. Another patient remains exquisitely light-sensitive after 20 years and has developed two squamous cell carcinomas, one of which metastasized to local lymph nodes, and two keratoacanthomas on light-exposed skin.
The Allergen Bank: a source of extra contact allergens for the dermatologist in practice.
Authors: Andersen KE , Rastogi SC , Carlsen L.
Published: June 2023

The Allergen Bank was established to give dermatologists easy access to special test materials in order to make early diagnoses of special cases of allergic contact dermatitis. The Allergen Bank comprises a computer system to register several hundred contact allergens in appropriate patch test concentrations available at the allergy laboratory and the patch test results. At the request of dermatologists in practice for Allergen Bank may supply special contact allergens for aimed patch testing of contact dermatitis patients. The organization of the Allergen Bank and the procedure of its use are described. During its first 23 months 28 dermatologists asked for 2,209 allergen samples for testing of 386 patients, an average of 6 allergens per patient and 14 patients per dermatologist. A total number of 164 positive reactions have been registered, and 440 of the 540 allergens have been in use. One third of the positive reactions were caused by the 16 most frequently ordered allergens, which amounted to 340 allergen samples. The allergens included plant chemicals, acrylates, animal feed additives, fragrance chemicals and preservatives. Selected allergens were investigated for stability during handling and shipping under varying conditions relevant to the function of the Allergen Bank. The possible inhomogeneity of petrolatum based allergen preparations is discussed in relation to diagnostic patch testing.
