RESUMEN

Background: Phobia as a psychological disorder seems to be aggravated during health crises like the current COVID-19 outbreak. On the other hand, people's knowledge about a situation can help decrease the resulting fear. Study design: This is a cross-sectional analytical study to evaluate the COVID-19 related phobia and to measure knowledge, attitude, and practice of our target Iranian population about COVID-19. Methods: In this study, DSM-5 specific phobia questionnaire, adapted to SARS-CoV2-19 infection, was used to evaluate the COVID-19 related phobia. Moreover, the knowledge, attitude, and practice (KAP) questionnaire, specific for SARS-CoV-2 infection, was applied. Results: Phobia score was significantly higher in 1st-degree relatives of healthcare staff (20.38±5.82) than healthcare staff (18.36±5.68) (p=0.021). Females showed a significantly more severe phobia (20.27±5.41) than males (17.72±5.35, p=0.001). COVID-19 phobia was significantly more severe in those with past psy-chiatric conditions than in those without psychiatric history (p<0.05). The 1st-degree relatives of healthcare staff had a significantly lower level of knowledge about SARS-CoV-2 infection (8.19±1.65) than healthcare staff (9.08±1.28, p=0.001). Additionally, age had a positive significant correlation with knowledge and practice towards SARS-CoV-2 infection. Conclusion: Both Iranian healthcare staff and 1st-degree relatives of healthcare workers are suffering from moderate COVID-19 phobia. Females are more concerned than males about COVID-19. Phobia is more severe in people with underlying psychiatric conditions than other people. The knowledge level of Iranian healthcare workers and 1st-degree relatives of healthcare staff about COVID-19 is acceptable but it needs improvement in certain areas.

RESUMEN

Introduction: The outbreak of Coronavirus Disease 2019 (COVID-19) have changed into a global crisis. Psychologically, this process of alteration can lead to feelings of fear, insecurity, and anxiety. This fear and anxiety can be caused by a variety of factors. However, due to the lack of extensive studies at this time, there are little data on these conditions related to COVID-19. Therefore, in this narrative review, we have tried to identify the most important possible causes of anxiety and fear due to this disease, based on logical shreds of evidence. Then we tried to discuss the consequences and ways to manage and prevent them. Methods: The current focus was on three major axes of corona-phobia, fear and anxiety. PubMed, Science Direct, Scopus, Google Scholar and authoritative news and information sources were considered as the data sources. Results: Findings from the analysis of the results revealed that, in addition to the real and the logical reasons which belong to the intrinsic properties of SARS-CoV-2, some misleadings and misconceptions induced by media, governmental policies, public awareness level, and non-scientific speculations and contradictory data expressed by experts, researchers and scientific societies, could provide the way for the development of corona-phobia, and fear. Conclusions: Each of these causal components, in its place, leads to some degrees of psychological disorders and subsequent consequences and complications. Finally, here we reviewed, summarized the previous research findings on how to prevent and manage this type of psychological disorder, and made comparisons.

RESUMEN

INTRODUCTION: Imatinib is the treatment of choice in patients with locally advanced or metastatic gastrointestinal stromal tumours (GIST). Clinical tolerance of imatinib is excellent except for the common adverse drug reaction (ADR). Drug rash with eosinophilia and systemic symptoms (DRESS syndrome) is a severe, potentially life-threatening drug-induced hypersensitivity reaction, characterized by cutaneous eruptions, fever, diffuse lymphadenopathy, along with eosinophilia, and elevated liver function tests. This ADR is rarely reported with imatinib. Only four cases of DRESS syndrome associated with imatinib have already been published. CASE REPORT: We report an exceptional case of DRESS syndrome associated with imatinib in a 46 year-old woman with GIST. Two weeks after she had started imatinib therapy, she developed a skin rash, with eosinophilia and elevated liver tests. Plasma level of imatinib was within the therapeutic range. Imatinib was immediately discontinued. A favourable outcome was slowly observed after the drug had been stopped. RESULTS AND CONCLUSION: This case was scored three according to the European Registry of Severe Cutaneous Adverse Reactions Study Group (RegiSCAR). The Naranjo score for imatinib was five (probable).

RESUMEN

The heat shock protein 90 (Hsp90) is a copious and ubiquitous molecular chaperone which plays an essential role in many cellular biological processes. The objective of this study was to identify single nucleotide polymorphisms (SNPs) in the Hsp90AA1 gene and to determine their association with heat stress traits in Chinese Holstein cattle breed. Direct sequencing was used to identify new SNPs. Luciferase reporter assay methods were used to assess g.- 87G > C and g.4172A > G loci in the promoter activity and 3'-UTR, respectively. Quantitative real-time PCR was utilized to quantify the gene expression profile. Five SNPs were identified in 130 multiparous lactating cows: one SNP in the promoter, three SNPs in the coding region, and one in 3'-UTR were novel and reported for the first time in this study. As a result of promoter assay using dual luciferase assay system, the genotype CC showed the highest transcription activity region (13.67 ± 0.578) compared to the wild-type GG (3.24 ± 0.103). On the other hand, the result revealed that one of the selected microRNAs (dme-miR-2279-5p) was found to interact with the Hsp90AA1 3'-UTR sequence and to suppress the reporter activity markedly in the presence of the allele G (2.480 ± 0.136). The expression of Hsp90AA1 in cow bearing mutant allele C was higher (4.18 ± 0.928) than cows bearing wild-type allele G (1.008 ± 0.0.129) in stress season. In summary, there was an association between genetic variations in the Hsp90AA1 and thermoresistance. This association could be used as a marker in genetic selection for heat tolerance in Chinese Holstein cattle breeds.

RESUMEN

In the present study the melatonin receptor 1A gene (MTNR1A) was proposed to be a candidate gene for egg production in Yangzhou geese. A total of 210 goose blood samples were collected to investigate the association of the MTNR1A gene with the number of eggs produced. Using a direct sequencing method, a single nucleotide polymorphism (SNP; g.177G>C) was detected in the 5' regulatory region of the MTNR1A gene (Genbank ss1985399687). Two alleles (G and C) and three genotypes were identified. Association analysis results showed that the g.177G>C SNP significantly affected the level of egg production within a 34-week egg-laying period (P < 0.05). Furthermore, the geese with the GG genotype produced significantly more eggs compared to the geese with the CC genotype. Quantitative real-time PCR analysis showed that the MTNR1A gene was highly expressed in small intestine, granulosa cell and ovary compared to other examined tissues. In addition, the mRNA expression level of MTNR1A in ovary indicated that significantly higher expression levels were recorded for geese with the GG genotype compared to those with the CC genotype. Moreover, a luciferase reporter assay showed that the CC genotype had significantly lower promoter activity than did GG. These results suggest that the identified SNP in the MTNR1A gene may influence the number of eggs produced and mRNA expression levels in Yangzhou geese and could be considered as a useful molecular marker in goose selection and improvement, especially for egg production.

RESUMEN

BACKGROUND: Punctate palmoplantar keratoderma type I (PPPK-BFB), also called Buschke-Fischer-Brauer disease (MIM 148600) is a rare autosomal dominant disorder of keratinization, characterized by multiple hyperkeratotic lesions on the palms and soles. Recently, PPPK-BFB has been shown to be associated with mutations in the AAGAB gene in several families of European, African, Canadian and Asian origins. OBJECTIVE: To characterize the clinical and genetic features of PPPK-BFB in a broad group of Tunisian patients. METHODS: Epidemiological and clinical data were collected from 18 PPPK-BFB patients belonging to eight Tunisian families. We carried out mutational and structural analysis for families not previously investigated. RESULTS: Sequencing of the remaining families identified a total of three different mutations in AAGAB gene: one founder mutation (c.348_349delAG, p.R116Sfs*1) specific to the inbred Tunisian population, one recurrent mutation and (c.370C>T, p.R124*) one novel variant (c.430C>G, p.E144K). This novel mutation, involving a conserved amino acid, is predicted to be probably damaging to the p34 protein function. Assessment of the phenotypic presentation of this group of Tunisian patients was marked by variable severity and varying age at onset with a possible presence of anticipation noted in five out of eight families (62.5%). There is no apparent genotype-phenotype correlation. Despite the high degree of inbreeding, no homozygous individuals for AAGAB mutations were observed. Homozygous carriers in AAGAB gene are likely non-viable. CONCLUSION: This study contributes to further characterize PPPK-BFB in consanguineous families and to extend the mutational spectrum of AAGAB gene in the Tunisian population.

RESUMEN

BACKGROUND: Mucosal leishmaniasis (ML), which mostly occurs in the New World, is mainly associated with Leishmania braziliensis. Primary lip ML is very rare in the Mediterranean basin and particulary in Tunisia despite the endemicity of both cutaneous and visceral leishmaniasis in this area. OBJECTIVES: To highlight a recent emergence of primary lip ML in Tunisia, to describe its epidemiological and clinical features and to identify the causative Leishmania species. METHODS: Epidemiological, clinical and therapeutic data of 10 cases presenting a ML of the lip were collected. Diagnosis confirmation of leishmaniasis was obtained by microscopic examination of Leishmania parasites in Giemsa stained smears of the lesion sampling and in cutaneous biopsies. Polymerase chain reaction (PCR) detecting Leishmania DNA directly from dermal scraping was also performed for diagnosis and species identification. RESULTS: Seven men and three women with lip ML were diagnosed during the last 6 years (2008-2013). The mean age was 29.7 years. Clinical presentation was characterized by an infiltrated and ulcerated plaque leading to macrocheilitis involving the upper lip in eight cases and the lower lip in two cases. Mean diagnosis delay was 6.9 months. PCR identified L. infantum in seven cases and L. major in two cases. Seven patients received intramuscular injections of meglumine antimoniate (MA) and three patients received both MA intralesional injections of MA and cryotherapy. A clinical remission was rapidly observed in all cases (on average in 2.2 months). CONCLUSIONS: Primary lip ML is emerging in Tunisia. Macrocheilitis of the upper lip is the main clinical presentation. PCR revealed more sensitive than direct examination in the diagnosis of such form (P < 0.01). Leishmania infantum was the most identified species (7 cases) while L major was involved in only two lesions. A benign local evolution and a rapid recovery were observed in all cases after MA treatment.

RESUMEN

BACKGROUND: Erythrasma is a chronic bacterial infection due to Corynebacterium minutissimum, affecting the interspaces of the toes, the axillary folds and the groin. Its impact is underestimated as it is often misdiagnosed ad wrongly taken as a dermatophytic infection. AIM: Through a hospital series, we report the epidemiologic and clinical features of erythrasma, as well as the therapeutic ways. methods: A retrospective study over a 20 year period and including the patients diagnosed as having erythrasma after a Wood's light examination. results: There were 16 patients (6 males and 10 females) with an average age of 44.6 years-old. The majority of our patients consulted on hot season. Clinical examination showed macular plaques with clear limits, erythematous in 6 cases and yellowish in the remaining cases. The lesions were located at the axillary folds in 13 cases; the groin in 2 cases and at all folds in one case. Treatment with erythromycin (topical or general administration) was the most prescribed. Outcome was generally favourable, but recurrences have been noticed. CONCLUSION: Erythrasma is a frequent misdiagnosed infection and often confused with a mycosis (especially in the interspaces of the toes); knowing that antimycotic agents are efficient in erythrasma. This is probably the reason of the small number of patients in our series.

RESUMEN

BACKGROUND: Bowen's disease (BD) is a form of in situ SCC, characterized by chronic and progressive course, with low potential for invasive malignancy. AIM: To assess epidemiology and clinical features of BD in a Tunisian cohort. METHODS: A retrospective study of 9 cases of BD managed in a Tunisian dermatology department. RESULTS: There were 7 males (77.8%) and 2 females (22.2%). The mean age of patients was about 68.8 years (46-89). Lesions were solitary in 7 cases and occurred in various sites: face (1 patient), trunk (2 patients), limbs (6 patients). The mean diameter of the tumour was about 3.4 cm. Lesions presented clinically as an enlarging well demarcated erythematous plaque with irregular borders and crusted or scaling surface. Histological examination showed in all cases abnormal keratinocytes with disordered maturation and loss of polarity replacing the epidermis in its whole thickness. The main treatment was surgery (N=5). Only one patient had radiotherapy (case 1). Outcome was mentioned in 2 patients who remained free from recurrence respectively after a follow-up of 1 and 12 years. CONCLUSION: Our series outlines epidemiological and clinical features of BD in Tunisia through a small but representative sample. As in the literature, this condition prevailed mainly over 60 years. In our study, BD occurred predominantly in men and affected nonexposed sites in 8 cases. This profile is uncommon in a sunny country in Tunisia, in the absence of other aetiological agents.

RESUMEN

Smooth muscle tumours arising in the skin are divided into angioleiomyomas, genital leiomyomas and pilar leiomyomas. Limited data about solitary leiomyoma are available in the literature. We herein report a case of a 66-year-old man who presented to our department with a slowly progressing cutaneous tumour of the right scapular area that had developed over the past 12 years. Histopathological and immunohistochemical results were consistent with the diagnosis of pilar leiomyoma. Pilar leiomyoma is a benign smooth muscle tumour arising from arrector pili muscle. Tumours can be painful from compression of cutaneous nerves or because of fibre contraction within the tumour in case of cold weather or emotional stress. This case is noteworthy as the piloleiomyoma was solitary, located on the trunk and had an unusual nipple aspect.

RESUMEN

Annular lichen planus is a rarely reported variant of lichen planus (LP). Although genital lesions are frequent in patients with LP, isolated genital LP is rarely reported. We present a case of a 29-year- -old circumcised man with an asymptomatic annular lesion of the penis. Histopathological features were consistent with LP. Topical clobetasol was prescribed, with clinical improvement. It is important to consider annular LP among the possible diagnoses of individual annular genital lesions.

RESUMEN

Adenolipoma of the skin (ALS) is an uncommon histological variant of lipoma, characterized by the presence of normal eccrine sweat glands inside the fat proliferation. A 32-year-old woman presented to our department with a slow-growing, painless subcutaneous soft tumour located on the upper part of the right thigh. Microscopically, there was lobulated adipose tissue proliferation with well-differentiated eccrine glands and ducts in the periphery and centre of the nodule. These features were suggestive of ALS. ALS is a rare microscopic variant of cutaneous lipoma having similar clinical features to lipoma. The most frequent locations of this tumour are thighs (as in our patient), shoulders, chest and arms. Histologically, the tumour is composed of lobulated adipose tissue with larger and more prominent lobules than those in normal subcutaneous adipose tissue. A well-developed capsule may also be identified. Eccrine glands and ducts, without proliferative changes, are well-differentiated within the adipose tissue. Differential diagnosis of adenolipoma includes the common lipoma and its variants, skin tag and other hamartomatous lesions, such as nevus lipomatosus superficialis, and the lipomatous variant of eccrine angiomatous hamartoma.
