Performance Evaluation of Wifi-6 with various Modulation and Coding Schemes
Authors: Saxena Ankit
Published: March 2023

For evaluation of the performance of wireless local area networks,
the radio characteristics between the access point (AP) and client
station (STA) in the same basic service set must be measured (BSS). Many
wireless networks coexist and may uncontrollably overlay in a specific
hotspot area because of the enormous demand for wireless services in
numerous applications. The performance of wireless radio channels is
affected because they are subject to interference from surrounding
energy, that direct impact on the throughput of both individual users
and networks. This problem can be resolved by a new spatial reuse IEEE
11ax feature that performs a clear channel assessment procedure between
the access point and client before assigning the channel for traffic,
thereby reducing channel collision and facilitating the wireless
network’s effective use of radio resources. Additionally, the usage of
radio channels would be limited on radio quality, resource availability
and the interference of overlaying networks. The work assesses the
performance of the spatial reuse feature using a clear channel
assessment approach in conjunction with some modulation and coding
schemes. After examination, we found that spatial reuse capability
improves the channel’s throughput performance by 18% to 20% higher
than conventional approaches for the lower Modulation and coding
scheme.

Integrating supervised segmentation and internet reputation as a form of
medical visual segmentation, biomechanical configurations are extracted
from retinal images. In this analysis, medical digital image clustering
techniques are highlighted, followed by an advance including
thresholding and micro and macro segmentation. Also, the attributes were
retrieved using either algorithm. Based on the gathered features, CNN,
PNN, and MLP are used to investigate and diagnose the bone crispiness. A
texture categorization framework is proposed, which offers superior
classification scenarios, based on the preliminary predictors. As a
result, it shows whether or not the claims are fragmented.
Employer Branding: How Perception of Social Media Use and Prior Work Experience Impacts Employer Attractiveness for Prospective Employees
Authors: Shahid Saad , Ayyaz Ibrahim
Published: March 2023

The current study aims to extend Sivertzen et al. (2013)’s proposed model to garner insights pertaining to employer branding, social-media use, work experience and intention to apply for prospective applicants within the Pakistani context and, creating a more cohesive view of employer branding for academics and practitioners. Questionnaire data was collected from 220 MBA students of varying levels of professional experience from Pakistani universities about their perceptions of potential employers and their intention to apply. Data analysis carried through Structural Equation Modeling (SEM) revealed that employer attractiveness dimensions such as “Economic Value” and “Development Value” were significantly linked to a company’s “Corporate Reputation” which in turn was linked to “Intention to Apply”; additionally, Social-Media Use was identified as a moderator for the relationship between Corporate Reputation and Intention to Apply. These results highlight the impact perceived functional social and psychological benefits have on the interaction between individuals and organizations and, the influence of social-media during the recruitment process and can. From a managerial standpoint, the results underscore the importance of understanding the needs of the workforce and, of curating an effective corporate reputation for recruitment purposes

Assessment of condylar position in asymptomatic individuals before and after neuromuscular deprogramming with a stabilization splint
Authors: Demirovic Kenan , Demirovic Elma , Dzemidzic Vildana , Nakas Enita
Published: March 2023

Introduction/Objective. Deprogramming of the neuromuscular system with the use of stabilization splint might provide more precise evaluation of the centric relation (CR) ? maximum intercuspation (MI) discrepancy. The study aimed to evaluate the differences between the bite registrations obtained in the CR before and after the application of the stabilization splint therapy. Methods. The sample included 48 non-deprogrammed individuals without any apparent signs and symptoms of temporomandibular disorders (TMDs). The neuromuscular system was deprogrammed by employing stabilization splint therapy. A condylar displacement evaluation was performed on vertical, horizontal, and transverse planes of space, with the assistance of a condylar position indicator. Results. The mean values of condylar displacements, which were obtained after the deprogramming of the neuromuscular system, were significantly greater than those obtained before neuromuscular deprogramming for vertical condylar displacement (p < 0.0001). A greater degree of condylar distraction was observed on the left side of the vertical plane before (p < 0.01) and after neuromuscular deprogramming (p < 0.05). The highest level of condylar displacement occurred in the postero-inferior direction subsequent to the muscle deprogramming. Conclusion. It was observed that the level of average condylar displacements was significantly higher following the deprogramming of the neuromuscular system compared to that recorded before neuromuscular deprogramming using stabilization splint therapy. A more precise orthodontic diagnosis could have been obtained if the condyles were placed in a more exact CR position by muscle deprogramming.
The CFD analysis of the effect of internal peak angle and mass-flow rates on the thermal performance of solar air heater with triangle cross-section
Authors: Ben Amara Walid , Aryanfar Yashar , Koten Hasan , Bouabidi Abdallah , Chrigui Mouldi , Alcaraz Jorge Luis
Published: March 2023

A new design of solar air heater with triangle cross-section is numerically studied. The thermal performance of solar air heater is studied at various mass-flow rates, inlet air temperatures, and solar irradiation intensities. The CFD model is developed using the software ANSYS FLUENT to study the fluid-flow and heat transfer in the solar air heater. The 3-D discretization is applied to study the thermal performance of solar collector with triangle cross-section. Mesh independence is performed in order to choose the adequate mesh. The discrete ordinate radiation model and the RNG k-? turbulence model are used to study the radiative heat transfer and the turbulent flow inside the solar air heater. Particularly, effects of different internal peak angles (145?,126?, 100?, 80?, and 67.5?) under different solar irradiation intensities (from 620-1081 W/m2) are studied to improve the thermal performance of the solar air heater. The results show a good agreement between the numerical model and the experimental data with an average error of 6%. The maximum outlet air temperature of the solar air heater reached 72 ?C for the geometries with 12 and 16 channels (internal peak angles of 80? and 67.5?, respectively) under mass-flow rate of 0.0264 kg/s. The thermal performances of the solar air heater with 16 and 12 channels are 24.2% higher than standard geometry, respectively for solar irradiation intensity of 1081 W/m2. The configuration with internal peak angle of 80? and 12 channels is selected as the optimal with a thermal efficiency of 79%, a low pressure drops compared to geometry with 16 channels and lower costs.

Authors: Marinkovic Ana , Savic Jasmina , Mladenovic Milica , Buha-Markovic Jovana , Petrov Nevena
Published: March 2023

Despite many benefits of agricultural biomass utilization as an energy source, there are certain disadvantages such as the possible high emission of NOx. The NOx emission represents one of the key challenges for agricultural biomass use as a fuel. The experimental denitrification chamber was used to evaluate the impact of initial NO content, NH3:NO molar ratio, flue gas temperature, and the temperature difference between two denitrification chamber sections on NOx reduction using ammonia aqueous solution. The optimization of experimental conditions was done in the NO concentration range from 200-800 ppm, NH3:NO molar ratios from 0.31-3 and second chamber section temperature range from 770-67?C. The denitrification process under controlled conditions is the starting point for the optimization of the secondary denitrification technique of selective non-catalytic reduction SNCR process on real-scale plants combusting biomass or any other fuels with increased NOx emission.
Impact of P-1 radiation model on simulated free jet flame characteristics of gaseous fuels: CFD with PDF approach
Authors: Elattar Hassan , Specht Eckehard , Almohammadi Bandar , Mohamed Mohamed , Refaey Hassanein
Published: March 2023

Simulation and analysis of a turbulent free jet flame erupting into still air are done using CFD. Using 2-D axisymmetric numerical modelling in ANSYS-FLUENT 14.5. Three distinct kinds of gaseous fuels are used: CH4, CO, and biogas (50% CH4 and 50% CO2). The effects of thermal radiation modelling utilizing the P-1 radiation model on the behavior of a free jet flame are investigated, and the impacts of air temperature and fuel velocity on the flame length are also provided. The findings demonstrated that the radiation modelling did not affect the temperature distribution and flame length for CO and biogas (i.e., lower heating value fuels). Nevertheless, the air temperature and fuel kind considerably impact the flame behavior. While the fuel inlet velocity (i.e., burner power) does not affect the flame length. Additionally, free jet flame velocity and length numerical correlations considering radiation modelling are predicted and presented with allowable errors. A comparison with earlier experimental correlation proved successful, with a maximum error of ?9.4%.
Biochemical analysis of dermis and urine in generalized scleroderma
Authors: Blumenkrantz N. , Asboe-Hansen G.
Published: March 2023

The urinary excretion of uronic acid and the hydroxyproline of a urinary fraction of high molecular weight collagen peptides (% of total Hyp) indicate disease activity in generalized scleroderma. A significant decrease in the content of Hyp and Hyl in the skin of sclerodermal patients is not related to activity, but rather to the duration of the disease. Parallel analyses of skin and urine of the same patients are reported.

Published: March 2023

Dopa and 5-S-cysteinyldopa levels in serum of albino, red, and black guinea-pigs were quantified. The levels of both amino acids were lower in the albino than in the pigmented animals. It is suggested that the serum levels of dopa and 5-S-cysteinyldopa in pigmented animals reflect tyrosine and dopa oxidation activity in the melanocytes.
C3b receptor in normal human oral mucosa
Authors: Thyresson HN. , Schroeter AL.
Published: March 2023

The presence of a receptor for C3b in normal human oral mucosa was studied using C3b produced by treating normal human serum with cobra venom factor. Cryostat sections of normal human oral mucosa were incubated with C3b, followed by a direct immunofluorescence technique using monospecific goat-antihuman C3. The histologic localization of C3b fluorescence was determined by fixing cryostat sections with glutaraldehyde and staining with hematoxylin and eosin. The endothelial cells of the capillaries and smaller venules in the oral mucosa showed staining by anti-C3. C3b did not bind to the intercellular substance nor to the basement membrane zone of normal human oral mucosa. Normal human serum treated with EDTA was negative, thus indicating that native C3 did not bind to the receptor. The endothelial C3b receptor of the oral mucosa may have an important function in the localization of immune complexes that occur in systemic diseases, as well as in diseases restricted to the oral mucosa.
Measurement and differentiation of the cellular infiltrate in experimental toxic contact dermatitis
Authors: Skoog ML.
Published: March 2023

Toxic (irritant) contact dermatitis was elicited by epicutaneous application of dinitrochlorobenzene (DNCB) and croton oil in unsensitized guinea pigs. The course of the skin reaction was studied with the naked eye, low-power microscopy, and a method based on counting of infiltrating cells in the upper corium. A weakly toxic dose of DNCB (100 microgram/cm2) gave marked erythema and moderate swelling, more pronounced 6 h after application of the DNCB than at 24 h or 48 h. A significant increase in mononuclear cells in particular but also in neutrophil and eosinophil granulocytes was noted in the upper corium. A more strongly toxic dose (500 microgram/cm2) gave a similar visible reaction, this too most marked at 6 h, but here there was an increase in neutrophil granulocytes in particular. Over and above predominant mononuclear-cell infiltration, croton oil (10 microgram/cm2) caused a slight increase in basophil cells. The reaction thus resembled a contact allergic reaction. In the light of earlier findings in allergic contact reactions the results suggest that weak stimuli, toxic or allergenic, elicit a non-specific skin response. With stronger stimulation the histological picture is modified and the cellular response acquires a pattern characteristic of toxic or allergic contact dermatitis.
Pityriasis lichenoides, an immune complex disease?
Authors: Faber WR. , Van Joost T.
Published: March 2023

Nine biopsies from skin lesions of 5 patients with pityriasis lichenoides acuta and three biopsies from skin lesions of 3 patients with pityriasis lichenoides chronica were examined by means of the direct immunofluorescence technique. IgM deposits along the dermoepidermal junction were found in only two biopsies. In the majority of bioipsies, complement (C3) deposits were found along the dermo-epidermal junction and in the vessel walls. Immunoglobulin and C3 deposits were not found concomitantly in the vessel walls.
Granuloma annulare: histopathologic and direct immunofluorescent study
Authors: Thyresson HN. , Doyle JA. , Winkelmann RK.
Published: March 2023

Eighteen cases of granuloma annulare were classified histopathologically and examined by direct immunofluorescence. The three different histopathologic types of granuloma annulare were compared with the result of immunofluorescence examination. No features of leukocytoclastic vasculitis were seen. Direct immunofluorescence of granuloma annulare does not reveal any consistent diagnostic pattern. Dermal desposition of fibrin in necrobiotic areas were noted in 8 cases of 18. Blood vessel and/or basement membrane deposition of IgM and C3 was inconsistent and does not support an immune complex vasculitis. Direct immunofluorescence is useful in studying the pathogenesis of granuloma annulare. The finding of fibrin, together with the histology, suggests to us a delayed hypersensitivity reaction as the dominant pathogenic event.

Authors: Verma KC. , Saini AS. , Dhamija SK.
Published: March 2023

The effect of zinc sulphate and placebo was compared in a double-blind trial in 56 patients suffering from acne vulgaris. Serum vitamin A levels were studied in all, before and at the end of therapy, 29 patients received zinc sulphate 600 mg daily and 27 patients received placebo. Patients on placebo showed no improvement. After 12 weeks of treatment with zinc sulphate, 17 patients (58%) showed significant improvement. There was a statistically significant decrease in the number of papules, infiltrates and cysts. In zinc-treated cases there was statistically significant increase in serum vitamin A levels, while no change was found in the placebo group.
Functional aspects on the Klippel-Trénaunay and related syndromes
Authors: Björkholm M. , Aschberg S.
Published: March 2023

Eight patients with two or three symptoms of the Klippel-Tr√©naunay triad were examined. All patients had varices, increased chloride concentration of sweat and, with one exception, hemangiomas. Four patients showed osteohypertrophy and one patient revealed signs of a-v fistulas. Venous outflow impairment as in deep venous occlusion is known to produce osteohypertrophy in children. The authors are of the opinion that a hemangioma actually is a functional a-v fistula. A hemangioma located in the vicinity of an epiphyseal zone may well cause a localized outflow impairment of the veins draining the epiphyseal zone, leading to an increased growth of the bone. Although patients with the Klippel-Tr√©naunay triad, Parkes-Weber syndrome and agenesis of the deep veins constitute an
Prostaglandin E1 treatment of leg ulcers caused by venous or arterial incompetence
Authors: Beitner H. , Hammar H. , Olsson AG. , Thyresson N.
Published: March 2023

An open and a double-blind study were undertaken on patients with leg ulcers caused mainly by venous (VI) or arterial incompetence (AI). They were treated with intravenous infusions or injections of prostaglandin E1 (PGE1). Eight of 10 patients in the open study experienced relief of pain and a complete or almost complete healing of their ulcers. In the double-blind study (20 patients) 4 out of 5 patients with a history of leg ulcers due to VI for more than 5 year responded to the PGE1 treatment, compared with one of 5 treated with saline. In the saline group 3 more patients with VI of shorter duration improved. In 3 of 5 patients of PGE1 with ulcers due to AI the original ulcer area was reduced by 78--65% after 70 days, while in the 2 remaining cases healing occurred later on. No effect was noted in the 2 patients with ulcers due to AI who received saline infusions. The results indicate the beneficial effect of PGE1 on pain and healing in leg ulcers caused by peripheral vascular disease.
Malignant melanoma and histiocytofibroma
Authors: Piette F. , Rozenberg M. , Vandenbussche F. , Bergoend H.
Published: March 2023

In patients with malignant melanoma, histiocytofibromas often appeared to be present. The frequency of this association has been determined in 60 female and 40 male patients, and compared with age- and sex-matched controls. Histiocytofibromas are significantly more common in females with malignant melanoma than in controls. This relationship is not found in males. Therefore, it would seem important to make a careful examination of nevocytic nevi in women having this benign tumour because of the high risk of developing a malignant melanoma.

Cutaneous eruptions and intrauterine contraceptive copper device
Authors: Frentz G. , Teilum D.
Published: March 2023

In the course of 6 months, 1888 intra-uterine contraceptive devices (IUCD) were inserted in a public clinic for contraception. In 10 of the women the IUCD subsequently had to be removed because of skin complaints. Four of these women as well as 3 out-patients of the Department of Dermatology. The Finsen Institute, who had been fitted with an IUCD were tested for metal allergy with closed patch tests and intracutaneous tests. None of the women was allergic to copper. One woman was allergic to nickel, which could be traced in minimal amounts in the copper wire of the IUCD, though causal connection between nickel in the IUCD and the skin symptoms is believed to be unlikely.

The ultrastructure of the dermo-epidermal junction in lichen planus
Authors: Clausen J , Kjaergaard J , Bierring F
Published: March 2023

The ultrastructure of the dermo-epidermal junctional area in biopsy material from 5 patients suffering from lichen planus has been studied during treatment with steroids. Tannic acid was used on the tissue blocks in order to provide high and diversified contrast for electron microscopy. The changes observed in the basal cells consisted mainly of degeneration of the mitochondria and disorganization of the tonofilaments. No ultrastructural changes were seen in the basal lamina, apart from occasional gaps, whose significance for pigment incontinence in old lichen planus lesions is discussed. Cellular infiltration was seen in the dermis, while the ultrastructure of the collagen fibrils of the papillary layer was normal. It is suggested that degeneration of mitochondria with subsequent disturbance of the organization and fixation of tonofilaments are events in the pathogenesis of the condition.
Cell-mediated reactivity in dermatophytosis: differences in skin responses to purified trichophytin in tinea pedis and tinea cruris
Authors: Kaaman T
Published: March 2023

Cell-mediated immune responses were measured in 91 patients with dermatophytosis by means of delayed-type skin hypersensitivity to a purified trichophytin preparation (ethylene glycol method) and to tuberculin (purified protein derivative, PPD). The findings indicate that dermatophytes differ in their sensitizing capacity as measured by trichophytin skin sensitivity. Trichophyton mentagrophytes appeared to be a potent sensitizer compared with Trichophyton rubrum (p < 0.01), whereas Epidermophyton floccosum appeared as a moderate sensitizer. The localization of infection also affected the cell-mediated response to trichophytin, i.e. the frequency of reactions was 44% in tinea cruris and 33% in tinea pedis, while tinea pedis with nail infections elicited delayed-type reactivity in 60% of cases. On the basis of the significant difference (p < 0.001) in cell-mediated reactivity between chronically and non-chronically infected subjects as measured with trichophytin, it is concluded that the cell-mediated response is of importance for the development of host resistance to dermatophytic infections. This study provides further evidenced in support of the view that a partial defect in the cell-mediated system may be responsible for establishment of chronic dermatophytosis.

Authors: Lassus A , Reunala T , Idänpää-Heikkilä J , Juvakoski T , Salo O
Published: March 2023

Altogether 525 PUVA-treated psoriatics were re-examined. The mean follow-up period since the beginning of PUVA therapy was 2.1 years (range 1-3.6 years). In 107 cases (20%) the total UVA dose was below 100 J/cm2 and in 20 (4%) over 1000 J/cm2. During PUVA treatment or at re-examination of 14 of the 525 patients (3%) were found to have skin lesions suspected of being malignant. A total of 23 biopsies were taken and in one case a basal-cell carcinoma was histologically verified. This had almost certainly been present before the beginning of the PUVA therapy. Two other patients, both previously treated with methotrexate, had reversible lesions with Bowenoid histology. Both these patients had received a total UVA dose of more than 1000 J/cm2. The incidence of skin carcinomas in the present PUVA treated series was lower than that in hospitalized psoriatics treated with regimens other than PUVA and was not higher than the incidence in the age-matched general population in Finland.

The effect of occlusion on the cutaneous microbial flora in patients with atopic dermatitis and psoriasis was measured. Significant increases in the density of Staphylococcus aureus and lipophilic diphtheroids were noted after occlusion in eczematous and psoriatic skins. While the incidence of S. aureus increased in psoriatic skin after occlusion, this trend was not noted in dermatitic skin.
An appraisal of routine direct immunofluorescence in vulvar disorders
Authors: Bushkell LL , Friedrich EG , RE Jr
Published: March 2023

Sixty-four biopsies were obtained from patients with a variety of vulvar disorders for direct immunofluorescence study. Twelve of 24 vulvar biopsies from patients with lichen sclerosus demonstrated deposition of fibrin in the upper dermis, while 7 vulvar biopsies showed fibrin deposition at the dermal-epidermal junction. Blood vessel immunofluorescence was observed in several patients but was not a disease-specific finding. Patients with pemphigus and pemphigoid yielded characteristic reactions and served as positive controls. Direct immunofluorescence may be of value in assessing patients with vulvar disorders, and in particular lichen sclerosus.
Granulomatous reaction in a red tattoo

Published: March 2023

A granulomatous reaction developed in the red part of a professionally executed tattoo. The reaction appeared a few weeks after tattooing. A patch test for mercuric bichloride proved negative. The localization to the red part of the tattoo implies a specific reaction to an unknown antigen, and that the reaction may denote a localized delayed hypersensitivity.

In a double-blind, randomized multi-centre study, 116 patients with psoriasis have been treated for 1-3 weeks with budesonide ointment (Preferid, Draco/Tika; a subsidiary of AB ASTRA), a new non-halogenated topical steroid. In a series of 11 patients a 0.025% budesonide ointment was significantly superior to placebo. In a second series, of 54 patients, a 0.025% fluocinolone acetonide ointment (Synalar, ICI). In a third series, of 51 patients, a 0.010% budesonide ointment was compared with 0.025% fluocinolone acetonide ointment. No statistically significant difference between these two preparations was found to exist. No adverse reactions were observed.

Authors: Igarashi R , Morohashi M , Koizumi F , Nitto H , Inomata N , Sato Y
Published: March 2023

In 16 patients with systemic lupus erythematosus, blood vessels in the affected region of the skin were examined regarding localization of immune complexes. Deposition of IgG, IgA, IgM, IgE, beta 1C and fibrin in the vessel walls was more frequently observed in intramural and perivascular sites than in intimal sites. IgM and fibrin were usually detected in intramural sites only. In large caliber arteries of the skin the intima was the main site of deposition of immune reactants, whereas, in small-caliber vessels, including capillaries, immune reactants were more often found in intramural and perivascular sites.
Is sebosuppression by cimetidine an antiandrogenic effect?
Authors: Gloor M , Wirth H , Swoboda U
Published: March 2023

By using the Syrian hamster ear model it is shown that cimetidine inhibits cell proliferation in the sebaceous gland. Furthermore, the S phase of sebaceous gland cells is lengthened and the number of labelled cells still in contact with the basal lamina of the sebaceous gland 6 days after isotope application related to the total number of labelled sebaceous gland cells is reduced. The effect of cimetidine is absolutely identical with that of cyproterone acetate, but is quite different from that of the nonhormonal sebosuppressive agent benzoyl peroxide.
Vitamin A transport complex during treatment with an oral aromatic retinoid (RO 10-9359)
Authors: Lauharanta J
Published: March 2023

No significant changes were noted in the serum levels or molar ratios of vitamin A, retinol-binding protein (RBP) and prealbumin even during long-term (up to 15 months) treatment with RO 10-9359 in 19 patients with normal renal function. Nor did any significant alteration occur in the highly significant correlations between vitamin A and RBP, and between RBP and prealbumin. In 3 patients with slightly elevated serum creatinine, some tendency towards an elevation of vitamin A and RBP levels was seen.
Oral disodium cromoglycate in mastocytosis
Authors: Zachariae H , Herlin T , Larsen PO
Published: March 2023

Oral disodium cromoglycate was found useful for the treatment of gastrointestinal manifestations of mastocytosis in 2 patients with systemic disease. The urinary excretion of histamine in these 2 patients decreased following treatment. Oral disodium cromoglycate had no effect on cutaneous symptoms, either in these 2 patients nor in 2 other patients with urticaria pigmentosa without signs of systemic mastocytosis. In the latter 2 patients the urinary excretion of histamine was unaffected. Treatment was given for 4 to 6 weeks and the dose of disodium cromoglycate was 100 mg four times daily in the 3 adult patients and 100 mg three times daily in the fourth patient, an 8-year-old boy.
Suppression of DNCB-induced irritant dermatitis by colchicine
Authors: Miyachi Y , Takigawa M , Imamura S
Published: March 2023

In vivo effects of colchicine on DNCB-induced primary irritant dermatitis in guinea-pigs were investigated with simultaneous evaluation of in vitro chemotactic activity of polymorphonuclear leukocytes (PMNs). Colchicine, 125, 250 and 500 microgram/kg, was injected intraperitoneally 1 hour prior to the painting of 20 microliter of 10% DNCB in acetone on shaved dorsum of the animals. In the control animals, erythema and induration were maximum and dermal PMN infiltration was most intense at 24 hours. In the colchicine-treated animals, induration--but not erythema--was reduced, with sparse dermal PMN infiltration. In vitro chemotaxis of PMNs from cardiac blood to LPS-treated serum using Boyden chamber techniques revealed maximal suppression of the activity in the colchicine injected animals at 12 hours. It is suggested that the reduced induration and decreased infiltration of PMNs in the inflammatory tissue in the colchicine-injected animals are caused by prior suppression of locomotion of PMNs in the peripheral blood.

Published: March 2023

We report the clinical variations and the duration of prodromal symptoms in 20 patients with bullous pemphigoid. Nearly two-thirds of the patients had prodromal symptoms. THe duration of the prodromal eruptions was up to 6 weeks if papular and/or urticarial and up to 2 years if eczematous, before the blisters appeared. Evidently longer prodromal periods were found in the present study than in earlier investigations. It is not known when in the course of the disease the direct immunofluorescence will be positive. Two of our patients were immunofluorescence-positive 1 and 2 weeks respectively before the blisters appeared. A common clinical manifestation in this study was vesicles on palms and/or soles. These eruptions, particularly as an early symptom, may cause misinterpretation in patients with bullous pemphigoid.

It was the purpose of this study to further define the nature of the dermal infiltrates in lymphomatoid papulosis (LP) means of enzyme cytochemistry (acid phosphatase and esterase), immunology (rosetting techniques, immunoperoxidase technique on cryostat sections), and by semithin and ultrathin sections. The studies performed on biopsy samples with clinically and histologically typical LP indicated that most lymphoid cells display markers for T-lymphocytes, which were helper T-cells in the one case studied with monoclonal antibodies. Regarding the typical benign self-involutive clinical course, LP is considered to be a cutaneous pseudolymphoma of T-cell type.

Natural killer cells and interferon production in atopic dermatitis
Authors: Strannegård Inga-Lisa , Strannegård Örjan
Published: March 2023

Natural killer (NK) cells, cytotoxic for Burkittl lymphoma cells, were found to be more active in atopic than in non-atopic children. Upon stimulation of lymphocyte cultures with Sendai virus, less interferon was produced by cells from atopic than from non-atopic individuals. lncreased NK activity and decreased interferon production may both be consequences of a T lymphocyte deficiency which has been suggested to be causally related to atopic disease.
Comparative study of the immune response involvement in atopic dermatitis and psoriasis
Authors: Guilhou Jean-facques , Clot Jacques , Meynadier Jean
Published: March 2023

Immunological and pharmacological disturbances in atopic dermatitis and psoriasis are compared. This comparative study revcaled several analogies: T cell deficiency; hyperfunction of B cells leading to antibody production, defect in the beta-adrenergic response. The role of immunological and pharmacological factors in the pathogenesis of the two diseases is discussed.

Poor outcome after debridement and implant retention for acute hematogenous periprosthetic joint infection: a cohort study of 43 patients
Authors: Westberg Marianne , Fagerberg Øystein Tyri , Snorrason Finnur
Published: March 2023

Background and purpose: The management of acute hematogenous periprosthetic joint infection (AHI) is challenging and the optimal treatment is not clearly defined. The aim of this study was to evaluate the treatment outcome of AHI, and secondarily to investigate potential risk factors that affect outcome.Patients and methods: We retrospectively analyzed 43 consecutive AHIs in a total hip or knee arthroplasty between 2013 and 2020 at a single center. We used the Delphi international consensus criteria to define infection. Patients were treated by either debridement, antibiotics, and implant retention (DAIR) (n = 25), implant exchange/removal (n = 15), or suppressive antibiotics only (n = 3). AHI was defined as abrupt symptoms of infection ≥ 3 months after implantation in an otherwise well-functioning arthroplasty.Results: AHI was most often caused by Staphylococcus aureus (16/43) and streptococcal species (13/43), but a broad spectrum of microbes were identified. 25 of 43 were treated with DAIR, with success in 10 of 25, which was significantly lower than in patients treated with removal of the implant with success in 14 of 15. S. aureus infection, knee arthroplasty, and implant age < 2 years were associated with treatment failure. The 2-year mortality rate was 8 of 43.Conclusion: The outcome following DAIR in AHIs was poor. The majority of infections were caused by virulent microbes, and we found a high mortality rate. Removal of the implant should more often be considered.
