Paniculite pancreática como a primeira manifestação de doença visceral: relato de caso

A paniculite pancreática, condição patológica rara, acomete 2-3% dos pacientes com doença do pâncreas. Em 40% dos casos, precede manifestações de doença pancreática. Relata-se caso de paciente feminina, 71 anos, surgimento há 1 mês de nódulos eritematosos nas pernas que evoluíram para ulceração e saída de conteúdo amarelado. Sem sintomas abdominais. A biópsia revelou macrófagos vacuolizados e necrose gordurosa representada por áreas anfofílicas, de material amorfo. Exame laboratorial e TAC demonstraram pancreatite crônica. Presume-se que a liberação de enzimas pancreáticas, tais como a tripsina, pode aumentar a permeabilidade da microcirculação e, então, a lípase e a amilase causariam a necrose de gordura subcutânea observada nas lesões. Na histologia, observam-se "células fantasmas" e paniculite septal de início e posteriormente lobular. O tratamento direciona-se a resolução da doença basePancreatic panniculitis is a rare pathological condition affecting 2-3% of patients with pancreatic disease. In 40% of cases the condition precedes manifestations of pancreatic disease. We report the case of a 71-year-old female who presented with an erythematous tender node which had appeared one month previously, progressing to ulceration and yellowish exudation. No abdominal symptoms. Biopsy revealed fat necrosis and vacuolated macrophages represented by amorphous amphophilic areas. Laboratory examination and CT scan revealed chronic pancreatitis. It is assumed that release of pancreatic enzymes such as trypsin may enhance the permeability of the microcirculation leading to lipase and amylase causing the subcutaneous fat necrosis observed in the lesions. Histology showed "ghost cells" and, firstly, septal panniculitis, followed later by lobular panniculitis. Treatment focused on resolution of the underlying pancreatic diseas

Pseudotumoural soft tissue lesions of the hand and wrist: a pictorial review

Mimickers of soft tissue tumours in the hand and wrist are more frequent than true neoplastic lesions. Pseudotumours belong to a large and heterogeneous group of disorders, varying from normal anatomical variants, cystic lesions, post-traumatic lesions, skin lesions, inflammatory and infectious lesions, non-neoplastic vascular lesions, metabolic disorders (crystal deposition disease and amyloidosis) and miscellaneous disorders. Although the imaging approach to pseudotumoural lesions is often very similar to the approach to “true” soft tissue tumoral counterparts, further management of these lesions is different. Biopsy should be performed only in doubtful cases, when the diagnosis is unclear. Therefore, the radiologist plays a pivotal role in the diagnosis of these lesions. Awareness of the normal anatomy and existence and common imaging presentation of these diseases, in combination with relevant clinical findings (clinical history, age, location and skin changes), enables the radiologist to make the correct diagnosis in most cases, thereby limiting the need for invasive procedures

Iranian Couples Conceptualization of the Role of Sexual Socialization in Their Sexual Desire: A Qualitative Study

Background: Some researchers consider sexual desire as a biological phenomenon, while others stress its psychological aspect. The question is why people experience different levels of sexual desire in different societies. This question can be answered from a sociological perspective. Objectives: This study aimed at exploring Iranian couples' perceptions of the role of sexual socialization in their sexual desire. Methods: This research had a qualitative thematic analysis method. Data collection was performed through 14 individual semi-structured interviews with seven couples, selected through purposive sampling. Thematic analysis was performed concurrently with data collection. Results: Analyzing participants' perceptions led to the extraction of 333 codes, five sub-sub-themes and two sub-themes "dual role of the parents" and "dual role of the community" in sexual development. The participants' dual role of parents, included parents' ability for sexual training of children and adolescents and the affectionate relationship between parents in the presence of children. Dual role of the community included sources of sexual information and sexual health education, beliefs and sociocultural taboos in sexual issues, and perception of couples from religious teachings about sexual issues. The main theme shared between sub-themes was "dual role of sexual socialization". Conclusions: Sexual desire was stronger in those whose sexual development had occurred in an active social context. In most cases, however, the couple's sexual desire had weakened because their sexual development had occurred in a passive social context. Educating sexual health experts, who can provide the sexual training needed at the individual, family, and community levels and act as reliable educational resources in line with the religious, cultural and social structure of the Iranian society seems necessary

HIV Prevention Services Received at Health Care and HIV Test Providers by Young Men who Have Sex with Men: An Examination of Racial Disparities

We investigated whether there were racial/ethnic differences among young men who have sex with men (MSM) in their use of, perceived importance of, receipt of, and satisfaction with HIV prevention services received at health care providers (HCP) and HIV test providers (HTP) that explain racial disparities in HIV prevalence. Young men, aged 23 to 29 years, were interviewed and tested for HIV at randomly sampled MSM-identified venues in six U.S. cities from 1998 through 2000. Analyses were restricted to five U.S. cities that enrolled 50 or more black or Hispanic MSM. Among the 2,424 MSM enrolled, 1,522 (63%) reported using a HCP, and 1,268 (52%) reported having had an HIV test in the year prior to our interview. No racial/ethnic differences were found in using a HCP or testing for HIV. Compared with white MSM, black and Hispanic MSM were more likely to believe that HIV prevention services are important [respectively, AOR, 95% confidence interval (CI): 3.0, 1.97 to 4.51 and AOR, 95% CI: 2.7, 1.89 to 3.79], and were more likely to receive prevention services at their HCP (AOR, 95% CI: 2.5, 1.72 to 3.71 and AOR, 95% CI: 1.7, 1.18 to 2.41) and as likely to receive counseling services at their HTP. Blacks were more likely to be satisfied with the prevention services received at their HCP (AOR, 95% CI: 1.7, 1.14 to 2.65). Compared to white MSM, black and Hispanic MSM had equal or greater use of, perceived importance of, receipt of, and satisfaction with HIV prevention services. Differential experience with HIV prevention services does not explain the higher HIV prevalence among black and Hispanic MSM
