Profiles of Pediatric Leprosy: A Report from a University Hospital of Nepal in the Post-Elimination Era.

Because pediatric leprosy strongly indicates continuous disease transmission in the community, knowing the profiles of pediatric leprosy is of great value for a leprosy-free world. We conducted this study to assess the clinical profiles of pediatric leprosy in Nepal. This retrospective study analyzed the 7-year record from 2011 to 2017. There were a total of 68 pediatric leprosy cases. Male (63.2%) cases outnumbered female cases. The minimum age of the leprosy-affected children was 6 years, with the mean age 12.17 (±1.95) years. Contact history was present in 26 (38.2%) children. Most of them (83.8%) had positive slit-skin smear. Lepra reaction was present in 14.7%. Nine had disability, with 4/9 (44.4%) of them having grade 2 disability. More than two-thirds (70.6%) were multi-bacillary cases. Some (2.9%) even had lepromatous leprosy. Leprosy continues to be a disease of concern in the post-elimination era even in the pediatric population.

Common mental disorders and associated factors among people with leprosy: cross-sectional analysis in Cuiabá, Brazil, 2018. / Transtornos mentais comuns e fatores associados entre pessoas com hanseníase: análise transversal em Cuiabá, 2018.

OBJECTIVE: To analyze the occurrence of common mental disorders (CMDs) and associated factors in people with leprosy with complications in the state of Mato Grosso, Brazil, in 2018. METHODS: This was a cross-sectional study with people attending Júlio Müller University Hospital. The Self-Report-Questionnaire (SRQ-20) was used. Poisson regression analysis was performed to estimate prevalence ratios (PR) and 95% confidence intervals (95%CI). RESULTS: Among 206 people with leprosy, CMDs were found in 70.4% (95%CI 61.10;76.67) and were associated with the female sex (PR=1.29 - 95%CI 1.09;1.53), the 26-45 age range (PR=1.52 - 95%CI 1.09;2.11) and the 46-60 age range (PR=1.40 - 95%CI 1.01;1.95), low family income (PR=1.25 - 95%CI 1.05;1.49), and unsatisfactory quality of life in the physical domain (PR=3.03 - 95%CI 1.12;8.19) and the psychological domain (PR=1.91; 95%CI 1.40;2.61). CONCLUSION: CMDs were frequent and associated with female sex, productive age group, low income and unsatisfactory quality of life. Actions aimed at mental health in this population group are necessary.

Histoid leprosy: clinical and histopathological analysis of patients in follow-up in University Clinical Hospital of endemic country.

BACKGROUND: Histoid leprosy (HL) is a rare form of lepromatous leprosy, characterized by hyperchromic indurated nodules above normal skin. Its main histopathological aspect is spindle cells. Because it may simulate other aspects, such as dermatofibroma and neurofibroma, histoid leprosy poses itself as a diagnostic challenge. METHODS: This is a retrospective study with all patients having been selected from the leprosy clinic of the Hospital das Clínicas da Universidade de São Paulo from 2006 to 2016. RESULTS: There were 12 patients in this study, eight in the histoid group and four in the lepromatous leprosy group. The prevalence of HL was 1.12% in all leprosy subjects. All individuals from HL group were "de novo" cases, and the histopathological analysis of skin lesions presented spindle cells generating a storiform pattern. Immunohistochemistry for CD68, vimentin, and anti-BCG were positive in all 12 cases. Factor XIIIa was visualized only in the papillary dermis, and S100 protein was negative in all biopsies. Smooth-muscle actin was present in 62.5% of the HL samples. CONCLUSION: The prevalence of HL was similar to previous reports. However, all histoid patients were "de novo" cases, differing from published studies. Fusocellular macrophage transformation could be explained by the differences in cytoskeleton proteins expressed in histoid lesions in comparison to other leprosy variants, with emphasis on vimentin and smooth muscle actin.

Clinical and epidemiological profile of leprosy patients attended at Ceará, 2007-2011.

BACKGROUND: Leprosy is an infectious chronic condition associated with potentially serious physical, social and psychological impacts. OBJECTIVES: To characterize the clinical and epidemiological profile of leprosy patients treated from 2007 to 2011 in the University Hospital of Ceará, Northeastern Brazil. METHODS: This is a retrospective and descriptive study. The study population consisted of residents in the state of Ceará treated in a dermatology clinic between 2007-2011. Clinical and epidemiological data analyzed were obtained from medical records and from the database of national Information System for Notifiable Diseases. RESULTS: 475 cases were analyzed, mostly women (51.8%), aged 45-59 years (35.0%) - mean of 45.2 years at diagnosis - with 6.3% of children under 15 , with low education (73.7%), white color (68.8%), residency in the city of Fortaleza (82.3%), and no defined work occupation (59.6%). At diagnosis, most patients were multibacillary (MB) (65.5%), had borderline clinical form (48.0%), and 22.7% had physical disability (8.0% with grade 2), predominantly in MB cases (p <0.001). We observe worsening of disability in 5.1% of cases post-MDT. The proportion of cases with reactional episodes was 42.7%, mainly during MDT (51.2%). CONCLUSION: This is the first study conducted in this hospital context, revealing late diagnosis, high burden of disease, hidden endemicity, and high social vulnerability in the state of Ceará. This study reinforces the need to strengthen health care network for timely diagnosis and treatment, aiming at longitudinality of assistance.

Prevalence and antibiotic susceptibility of Mycoplasma hominis and Ureaplasma urealyticum in genital samples collected over 6 years at a Serbian university hospital.

BACKGROUND: Mycoplasma hominis and Ureaplasma urealyticum are implicated in a wide array of infectious diseases in adults and children. Since some species have innate or acquired resistance to certain types of antibiotics, antibiotic susceptibility testing of mycoplasma isolated from the urogenital tract assumes increasing importance. AIMS: To evaluate the prevalence and antibiotic susceptibility of M. hominis and U. urealyticum in genital samples collected between 2007 and 2012. METHODS: Three hundred and seventy three patients presenting with symptoms of sexually transmitted diseases, infertility or risky sexual behaviour, who had not taken antibiotics in the previous 6 weeks and had ≥10 WBC per high power field on genital smears were studied. Urethral samples were taken in men and endocervical samples in women. The mycoplasma IST-2 kit was used for organism identification and for testing susceptibility to doxycycline, josamycin, ofloxacin, erythromycin, tetracycline, ciprofloxacin, azithromycin, clarithromycin and pristinamycin. RESULTS: U. urealyticum was isolated from 42 patients and M. hominis from 11 patients. From 9.8% of isolates, both organisms were grown. All M. hominis isolates were resistant to tetracycline, clarithromycin and erythromycin while U. urealyticum was highly resistant to clarithromycin (94.6%), tetracycline (86.5%), ciprofloxacin (83.8%) and erythromycin (83.8%). M. hominis was sensitive to doxycycline (83.3%) and ofloxacin (66.7%) while most U. urealyticum strains were sensitive to doxycycline (94.6%). LIMITATIONS: Inability of the commercial kit used in the study to detect other potentially pathogenic urogenital mycoplasmas (Ureaplasma parvum, Mycoplasma genitalium). CONCLUSION: There is significant resistance of U. urealyticum and M. hominis to tetracycline and macrolides. The most active tetracycline for genital mycoplasmas was found to be doxycycline, which continues to be the drug of first choice.

A Study of Clinical, Bacteriological & Histopathological Correlation in Leprosy Cases attending a Government Medical College in Western Odisha: Some Observations.

The study was undertaken in VSS Institute of Medical Sciences to observe the clinical, bacteriological and histological diagnosis of leprosy patients attending the hospital who consented to undergo slit skin smear (SSS) examination, punch biopsy and participate in the study. Fifty leprosy patients aged 5 to 70 years, which included 41 male and 9 female patients participated in the study. These included 4 TT, 24 BT, 2 BB, 5 BL and 15 ILL clinically diagnosed patients as per the IAL classification (1982 ). SSS were undertaken from 4 sites, stained with ZN stain and BI calculated as per Ridley Scale. Four patients were skin smear negative all TT). Of the 24 BT patients enrolled in the study, 11 were skin smear negative while 13 were smear positive (BI ranging from 1+ to 4+); Both the BB cases, all 5 BL cases, and all the 15 LL cases were smear positive (BI range 2+ to 6+). Histologically there was complete parity and correlation in.the TT group, while the correlation was observed to be 83%, 50%, 60%, and 93% in the clinically diagnosed BT, BB, BL and LL patients respectively. The sample size in the study was small, however, the overall bacteriological skin smear negativity/positivity correlation was observed to be 53.6% for paucibacillary (TT+BT) disease and 100% for MB (BB, BL and LL) disease Histological correlation was 100%, 83%, 50%, 60% and 93% respectively for clinically diagnosed TT, BT, BB, BL and LL disease. A sizeable number of BT patients were found to be bacteriologically positive and were therefore being treated with lesser number of drugs as well duration under programme conditions, Although there is inter-observer variation and overlapping of clinical and histological diagnosis in the borderline patients (BT, BB & BL), bacteriological and histological confirmation helps in deciding on adequate treatmeht and should be undertaken.

Leprosy in a University Hospital in Southern Brazil.

BACKGROUND: Leprosy is an infectious disease that may lead to irreversible nerve damage, compromising patient's quality of life and leading to loss of working years. OBJECTIVES: To evaluate the epidemiological profile of patients followed at a University Hospital. MATERIALS AND METHODS: This is a retrospective observational study, based on a review of medical records. We studied the clinical and epidemiological features of patients with leprosy monitored at the Hospital de Clínicas of the Federal University of Paraná between January 2005 and January 2010. RESULTS: The mean age was 47.51, while 35.94% of patients were aged 41-60. The male:female rate was 1.8:1. The most prevalent occupations were: retired, students or rural workers. Patients came mainly from Curitiba or nearby areas, but there were also patients from the countryside. The mean diagnostic delay was 24.57 months. Multibacillary forms prevailed, with the lepromatous variety being the most common, closely followed by the borderline type. Neural enlargement was found in more than 50% of the patients and 48.44% of them developed reactional states. Hemolysis was the most commonly detected drug side effect. Initial functional evaluation was possible in 70% of patients, 55% of whom had disabilities upon diagnosis. The most prevalent associated disease was hypertension. CONCLUSIONS: This study showed an important diagnostic delay and a high rate of sequelae in this specific population. Brazil is one of the few remaining countries that has not yet eradicated leprosy and it is important to improve health policies in order to prevent sequelae and achieve eradication.

Perfil epidemiológico da hanseníase em Hospital Universitário de Campinas, SP: explorando fichas de notificação / Epidemiological profile of leprosy in an Universitary Hospital in Campinas, SP: exploring notification protocols

Introdução: A documentação de casos novos de hanseníase em Fichas de Notificação é estratégia para auxiliar no controle da enfermidade, visto que delas são extraídas informações clínicas e laboratoriais de seus portadores. Objetivo: Explorar o conteúdo informacional das Fichas de Notificação de Casos Novos de hanseníase do Sistema de Informação de Agravos de Notificação atendidos no Hospital e Maternidade Celso Pierro em Campinas-SP, em período definido de estudo, com o escopo de traçar perfil epidemiológico local. Metodologia: Estudo observacional descritivo transversal em que a coleta de dados totalizou 97 Fichas de Notificação de Hanseníase, referentes aos anos de 2007 a 2013. Codificação mediante planilha padronizada, seguida de arquivamento na forma de banco de dados e análise estatística pelo Software SPSS e testes de Tukey e Kruskal-Wallis, complementada pelo teste de Dunn. Todas as inferências estatísticas foram realizadas ao nível 5% de significância. Resultados: A maioria dos casos revelou-se do sexo masculino, faixa etária de 15 a 44 anos, com lesões cutâneas em número superior a 5, multibacilar, virchowiana, com grau 0 de incapacidade física, baciloscopia negativa e esquema terapêutico inicial de12 doses. Constatou-se baixa detecção em menores de 15 anos, embora elevado número de doentes com grau II de incapacidade física, acima do valor definido pelo Ministério da Saúde como um dos critérios para diagnóstico precoce. Conclusões: O exposto sugere necessidade de notificação epidemiológica presente e constante, com registros de dados contínuos, além de padronização no ato de transcrição das informações nas Fichas de Notificação.

Introduction: The documentation of new leprosy cases in Notification Protocols is an important strategy for control, as clinical and laboratory aspects of the patients are extracted from the notifications. Objetive:To explore the information content in Notification Protocols about new cases of leprosy in the Information System for Notifiable Diseases attended on the Celso Pierro Hospital and Maternity in Campinas-SP, during a defined period, with the scope of describing the local epidemiological profile. Methodology: This is a cross-sectional observational study enrolling data refering to a total of 97 Notification Protocols of leprosy cases notified in the period from 2007 to 2013. Registers on codified sheets, storage in specific data base and statistical processing by SPSS program, Tukey and Kruskal-Wallis tests, complemented with the Dunn test. All the statistical inferences were performed with a 5% significance level. Results: Most of the cases were from male, the age group was from 15 to 44 years old, with skin lesions above 5, multibacillary, lepromatous, grade zero disabilities, negative smear and initial treatment received was multidrugtherapy/12 doses. The disease was found to occur less in people under 15 years old, although there is a high level of patients with grade two disabilities, which is a level above what is defined by the Brazilian Ministry of Health as one of the criteria to early diagnosis. Conclusions: This study suggests for better leprosy control the need of present and constant epidemiological notification, with recording of continuous data, besides standardizing the transcription of reporting forms.

[High complication rate after surgical treatment of ankle fractures]. / Høj komplikationsrate efter kirurgisk behandling af malleolfraktur.

The purpose of this study was to determine the quality and re-operation rate of the surgical treatment of ankle fractures at a large university hospital. X-rays and patient records of 137 patients surgically treated for ankle fractures were analyzed for: 1) correct classification according to Lauge-Hansen, 2) if congruity of the ankle joint was achieved, 3) selection and placement of the hardware, and 4) the surgeon's level of education. Totally 32 of 137 did not receive an optimal treatment, 11 were re-operated. There was no clear correlation between incorrect operation and the surgeon's level of education.

Childhood leprosy: a retrospective descriptive study from Government Medical College, Kozhikode, Kerala, India.

OBJECTIVE: To assess the profile and describe the clinical presentations and complications of childhood leprosy in a tertiary care hospital in North Kerala, South India during 2003-2012 and to analyse any change in the age-sex profile and the clinical pattern of leprosy in children below the age of 15 years over the 10-year study period. DESIGN: A retrospective descriptive study of children less than 15 years of age diagnosed with leprosy and registered for treatment in a tertiary care institution from 2003 to 2012. Demographic, clinical, investigative and treatment data were collected using a pre-set proforma. RESULTS: 138 (12.1%) of the total 1143 leprosy cases registered for treatment during the 10-year period were below 15 years of age. The 10-year study period witnessed a statistically insignificant decrease in the new childhood leprosy cases registered for treatment in our tertiary care institution. The majority of cases belonged to the 6-12 year age group (61.6%) with a male predominance. Borderline tuberculoid (BT) was the commonest clinical type (65.9%) followed by indeterminate leprosy (18.8%); 101 patients required paucibacillary (PB) and 37 needed multibacillary (MB) treatment. The number of patients requiring MB treatment showed a statistically significant increase and there was a significant decline in number of cases requiring PB treatment. During the entire study period no Type 2 lepra reaction was documented in patients below Hema 15 years and only two patients manifested Type 1 reaction. Ten (7.2%) out of the 138 patients were cases of relapse. There was a clear female predilection among relapse cases with the majority belonging to the adolescent age. CONCLUSIONS: Childhood leprosy still contributes to a significant proportion of the total case load denoting the continuing active horizontal transmission of leprosy. The rise in number of patients with more extensive disease in the background of declining disease prevalence is suggestive of the delay in diagnosis and treatment. A high relapse rate noted in the present study may be due to incorrect classification and treatment of MB as PB leprosy which in turn might have resulted in treatment failure due to inadequate treatment.

[Epidemiological survey of leprosy conducted in metropolitan France between 2009 and 2010]. / Enquête épidémiologique sur la lèpre en France métropolitaine en 2009 et 2010.

BACKGROUND: There is no official leprosy register in France. The last epidemiological survey on leprosy in metropolitan France was done between 1995 and 1998. We performed a new epidemiological study of leprosy in metropolitan France in 2009 and 2010. PATIENTS AND METHODS: We contacted 85 dermatology and infectious disease units by e-mail or by telephone in order to determine the number of leprosy patients either being followed up or newly diagnosed in 2009 and 2010. RESULTS: The response rate was 87%. In 2010, 127 patients were being followed up in metropolitan France, mostly at dermatology units (78%). Seventy-five patients were on anti-bacillary treatment and the prevalence was 0.011/10,000. There were 39 new cases diagnosed in 2009 and 2010 (mean 19 cases/year) (low case-detection rate: 0.003 per 10,000 inhabitants). Among the new cases, seven patients (18%) were of French origin, with two from metropolitan France and five from French overseas territories. DISCUSSION: Our study confirms the persistence of imported leprosy in France and shows no significant decrease in the number of new cases since 1998 (19 vs. 18 new cases/year) or in disease prevalence (0.013 vs. 0.011 per 10,000 inhabitants). This prevalence is very far removed from the one per 10,000 inhabitants proposed by the World Health Organization as the criteria for endemic disease. Most patients in our survey were immigrants (82%). Lepromatous forms (46%) were more frequent than the tuberculoid forms (33%). All patients had either travelled to or lived in areas of high leprosy prevalence, including metropolitan subjects. CONCLUSION: Leprosy remains present in metropolitan France, and it is still important to continue teaching about it at medical faculties in order to ensure diagnosis of new patients as early as possible.

Association of pulmonary tuberculosis and dermatological conditions among patients of a rural medical college hospital.

INTRODUCTION: Pulmonary tuberculosis (PTB) affects a significant proportion of the population. There are many contributory aetiological factors common to tuberculosis (TB) and dermatological conditions. AIM: To study the spectrum of concurrent skin conditions in patients with PTB and to compare with patients having other diseases. METHODS: All patients with PTB admitted to our Institute during the period of the study were included in the study. A comparable number of patients admitted in other departments constituted the control group. All patients were screened for skin diseases. RESULTS: There were 498 patients in each group, matched for age and gender. There were 126 patients with skin conditions in the study group as against 60 patients in the control group. Pityriasis versicolor was the commonest skin condition in both the groups. Whereas acniform eruptions and pruritis were more common in the control group. Pityriasis versicolor, herpes zoster, erythema nodosum and leprosy were significantly more frequent among patients. CONCLUSION: There is a high frequency of concurrent skin diseases in patient with PTB that should be managed along with it.

Quality of life in chronic urticaria: a survey at a public university outpatient clinic, Botucatu (Brazil).

OBJECTIVE: To evaluate the impact of chronic urticaria on quality of life of outpatients through the university questionnaire Dermatology Life Quality Index (DLQI). METHODS: Survey of the impact on quality of life caused by chronic urticaria, using the DLQI questionnaire validated for the Portuguese language. Patients were interviewed during visits to a specialized outpatient clinic between May 2009 and May 2010 at a Brazilian public service (Botucatu-SP). DLQI scores were analyzed according to the following subgroups: age, gender, education, disease duration, and presence of angioedema. RESULTS: We interviewed 100 patients with chronic urticaria. There was a female predominance (86%), mean age 41.8 years, mean disease duration of 6 years, and angioedema occurrence in 82% of patients. The mean DLQI score was 13.5, characterized by serious impact on quality of life, higher than Hansen's disease, psoriasis, atopic eczema, and basal cell carcinoma. The presence of angioedema was associated with higher scores: 14.5 x 9.9 (p < 0.01). Female patients reported greater impact on clothing, while male patients reported treatment interference with work and study (p < 0.05). CONCLUSION: Chronic urticaria seriously compromises the quality of life of patients evaluated at a university service in Brazil, particularly of patients with angioedema.

Dose calculation in biological samples in a mixed neutron-gamma field at the TRIGA reactor of the University of Mainz.

To establish Boron Neutron Capture Therapy (BNCT) for non-resectable liver metastases and for in vitro experiments at the TRIGA Mark II reactor at the University of Mainz, Germany, it is necessary to have a reliable dose monitoring system. The in vitro experiments are used to determine the relative biological effectiveness (RBE) of liver and cancer cells in our mixed neutron and gamma field. We work with alanine detectors in combination with Monte Carlo simulations, where we can measure and characterize the dose. To verify our calculations we perform neutron flux measurements using gold foil activation and pin-diodes. Material and methods. When L-α-alanine is irradiated with ionizing radiation, it forms a stable radical which can be detected by electron spin resonance (ESR) spectroscopy. The value of the ESR signal correlates to the amount of absorbed dose. The dose for each pellet is calculated using FLUKA, a multipurpose Monte Carlo transport code. The pin-diode is augmented by a lithium fluoride foil. This foil converts the neutrons into alpha and tritium particles which are products of the (7)Li(n,α)(3)H-reaction. These particles are detected by the diode and their amount correlates to the neutron fluence directly. Results and discussion. Gold foil activation and the pin-diode are reliable fluence measurement systems for the TRIGA reactor, Mainz. Alanine dosimetry of the photon field and charged particle field from secondary reactions can in principle be carried out in combination with MC-calculations for mixed radiation fields and the Hansen & Olsen alanine detector response model. With the acquired data about the background dose and charged particle spectrum, and with the acquired information of the neutron flux, we are capable of calculating the dose to the tissue. Conclusion. Monte Carlo simulation of the mixed neutron and gamma field of the TRIGA Mainz is possible in order to characterize the neutron behavior in the thermal column. Currently we also speculate on sensitizing alanine to thermal neutrons by adding boron compounds.
