To characterize maxillofacial, otorhinolaryngological and oral manifestations of Hansen's disease (HD), we conducted a cross-sectional study in 21 current patients attending the Unidade Básica de Saúde de Jardim América, Espírito Santo, Brazil and 16 former patients resident at Pedro Fontes Hospital using data from computed tomography imaging, rhinoscopy, and oroscopy. Maxillofacial characteristics were compared with 37 controls. Differences in bone alterations across the three groups were determined mainly by severe resorption/atrophy being more frequent in former HD patients, with severe resorption/atrophy of the anterior alveolar process of maxilla in 50.0% (8/16) of former patients, 28.6% (6/21) of current patients and 10.8% (4/37) of controls and of nasal bones and aperture in 31.3% (5/16) of former patients compared with 0/21 current patients and two controls. There were no substantial differences in otorhinolaryngological and oroscopic findings between the two patient groups. HD patients had more tooth loss than the age-matched control group. Maxillofacial, otorhinolaryngological and oroscopic finding scores were strongly correlated only in current HD patients. Correlation between otorhinolaryngological and maxillofacial scores suggests that protocols for HD patient assessment and follow-up could include otorhinolaryngological evaluation, with radiological imaging where necessary, subject to replication of our findings in a larger study., (© 2022.

Background More than four million people today live with Hansen's disease, and 200,000 new cases are diagnosed every year. Lifetime effects of Hansen's disease manifest as changes to bones of the face, hands and feet, resulting in physical impairment, secondary complications and facial changes that can be detrimental to quality of life, particularly among the elderly. Aims This study aimed to perform a detailed characterization of rhinomaxillary syndrome and its clinical manifestations in older persons treated in the past for Hansen's disease. Methods This was a cross-sectional study to characterize rhinomaxillary syndrome among older persons (age 60+ years) resident at Pedro Fontes Hospital, Cariacica, Espírito Santo, Brazil. Computed tomography images were examined with three-dimensional reconstructions to assess alterations to maxillofacial bones according to criteria for radiological rhinomaxillary syndrome. Participants were examined to assess facial alterations according to criteria for clinical rhinomaxillary syndrome. Results Rhinomaxillary syndrome was investigated in 16 participants (ten females and six males), median age 70 (range 60-89) years, age at diagnosis 20 (6-43) years and time since diagnosis 46 (26-70) years. Four participants fully met radiological rhinomaxillary syndrome criteria, four partially. All participants with full radiological rhinomaxillary syndrome presented with facial changes which met criteria for clinical rhinomaxillary syndrome, including "saddle nose" (loss of nasal dorsal height and shortened length of nose, due to cartilaginous and/or bone collapse), concave middle third of the face with sunken nose, maxillary retrognathia and inverted upper lip. Limitations Clinical histories were incomplete for some participants because records were lost at the hospital over time. Conclusion Until Hansen's disease is eliminated from endemic countries, persons affected will continue to present with rhinomaxillofacial alterations caused by Mycobacterium leprae infection. Clinical protocols for assessment and long-term care need to include otorhinolaryngological evaluation, mainly to prevent secondary complications. When rhinomaxillofacial bone changes are suspected, this evaluation should be supported by computed tomography imaging, if available.

Over the past few years, different Computer-Aided Diagnosis (CAD) systems have been proposed to tackle skin lesion analysis. Most of these systems work only for dermoscopy images since there is a strong lack of public clinical images archive available to evaluate the aforementioned CAD systems. To fill this gap, we release a skin lesion benchmark composed of clinical images collected from smartphone devices and a set of patient clinical data containing up to 21 features. The dataset consists of 1373 patients, 1641 skin lesions, and 2298 images for six different diagnostics: three skin diseases and three skin cancers. In total, 58.4% of the skin lesions are biopsy-proven, including 100% of the skin cancers. By releasing this benchmark, we aim to support future research and the development of new tools to assist clinicians to detect skin cancer., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships which have, or could be perceived to have, influenced the work reported in this article., (© 2020 The Author(s).)

Deformities of bones of the face and extremities are markers of leprosy (Hansen's disease) which contribute to stigma associated with this disease. Among these deformities are articular alterations that can mimic rheumatoid arthritis (RA). In this case, a 64-year-old man presented with a history of having been treated for lepromatous leprosy and erythema nodosum leprosum episodes, which evolved with joint alterations similar to those of RA. Most cases of leprosy-related arthritis are associated with reactional episodes, of which a large number do not respond to conventional therapy for leprosy reactions. In cases of chronic arthritis not associated with leprosy reactions, although patients show considerable relief with anti-leprosy therapy, arthritis is not completely resolved. This emphasizes the need for early diagnosis and treatment of leprosy to prevent the development of osteoarticular alterations.

We describe a case of nasal myiasis in an 89-year-old Brazilian patient affected by leprosy with severe nasal sequelae. An initial treatment comprising sinusectomy combined with nasal endoscopy removed more than 300 larvae, supplemented by systemic treatment using oral and topical ivermectin and levofloxacin. Infestation recurred after 2 months, was treated similarly, and resolved completely. The case could be attributed to severe nasal leprosy sequelae, with a lack of sneezing reflex, painless ulceration, atrophic rhinitis (ozena), and inability to clean the nose properly due to hand and nose impairment. This case illustrates the importance of long-term medical follow-up of patients with leprosy sequelae.
