Translumbosacral Anorectal Magnetic Stimulation Test for Fecal Incontinence.

BACKGROUND: Neuropathy may cause fecal incontinence and mixed fecal incontinence/constipation, but its prevalence is unclear, partly due to the lack of comprehensive testing of spino-anorectal innervation. OBJECTIVE: This study aimed to develop and determine the clinical usefulness of a novel test, translumbosacral anorectal magnetic stimulation for fecal incontinence. DESIGN: This observational cohort study was conducted from 2012 to 2018. SETTINGS: This study was performed at a tertiary referral center. PATIENTS: Patients with fecal incontinence, patients with mixed fecal incontinence/constipation, and healthy controls were included. INTERVENTIONS: A translumbosacral anorectal magnetic stimulation test was performed by using an anorectal probe with 4 ring electrodes and magnetic coil, and by stimulating bilateral lumbar and sacral plexuses, uses and recording 8 motor-evoked potentials at anal and rectal sites. MAIN OUTCOME MEASURES: The prevalence of lumbar and/or sacral neuropathy was examined. Secondary outcomes were correlation of neuropathy with anorectal sensorimotor function(s) and morphological changes. RESULTS: We evaluated 220 patients: 144 with fecal incontinence, 76 with mixed fecal incontinence/constipation, and 31 healthy controls. All 8 lumbar and sacral motor-evoked potential latencies were significantly prolonged (p < 0.01) in fecal incontinence and mixed fecal incontinence/constipation groups compared with controls. Neuropathy was patchy and involved 4.0 (3.0) (median (interquartile range)) sites. Lumbar neuropathy was seen in 29% to 65% of the patients in the fecal incontinence group and 22% to 61% of the patients in the mixed fecal incontinence/constipation group, and sacral neuropathy was seen in 24% to 64% and 29% to 61% of these patients. Anal neuropathy was significantly more (p < 0.001) prevalent than rectal neuropathy in both groups. There was no correlation between motor-evoked potential latencies and anal sphincter pressures, rectal sensation, or anal sphincter defects. LIMITATIONS: No comparative analysis with electromyography was performed. CONCLUSION: Lumbar or sacral plexus neuropathy was detected in 40% to 75% of patients with fecal incontinence with a 2-fold greater prevalence at the anal region than the rectum. Lumbosacral neuropathy appears to be an independent mechanism in the pathogenesis of fecal incontinence, unassociated with other sensorimotor dysfunctions. Translumbosacral anorectal magnetic stimulation has a high yield and is a safe and clinically useful neurophysiological test. See Video Abstract at http://links.lww.com/DCR/B728. PRUEBA DE ESTIMULACIN MAGNTICA TRANSLUMBOSACRAL ANORECTAL PARA LA INCONTINENCIA FECAL: ANTECEDENTES:La neuropatía puede causar incontinencia fecal y una combinación de incontinencia fe-cal/estreñimiento, pero su prevalencia no está clara, en parte debido a la falta de pruebas comple-tas de inervación espino-anorrectal.OBJETIVO:Desarrollar y determinar la utilidad clínica de una nueva prueba, estimulación magnética trans-lumbosacral anorrectal para la incontinencia fecal.DISEÑO:Estudio de cohorte observacional del 2012 al 2018.ENTORNO CLINICO:Centro de referencia terciario.PACIENTES:Pacientes con incontinencia fecal, combinación de incontinencia fecal/estreñimiento y controles sanos.INTERVENCIONES:Se realizó una prueba de estimulación magnética translumbosacral anorrectal utilizando una sonda anorrectal con 4 electrodos anulares y bobina magnética, y estimulando los plexos lumbares y sacros bilaterales y registrando ocho potenciales evocados motores las regiones anal y rectal.PRINCIPALES MEDIDAS DE RESULTADO:Se examinó la prevalencia de neuropatía lumbar y/o sacra.

Se observó neuropatía lumbar en 29-65% en la incontinencia fecal y 22-61% en el grupo mixto, y neuropatía sacra en 24-64% y 29-61 % de pacientes respectivamen-te. La neuropatía anal fue significativamente más prevalente (p <0,001) que la rectal en ambos grupos. No hubo correlación entre las latencias de los potenciales evocadas motoras y las presio-nes del esfínter anal, la sensación rectal o los defectos del esfínter anal.LIMITACIONES:Sin análisis comparativo con electromiografía.CONCLUSIÓNES:Se detectó neuropatía del plexo lumbar o sacro en el 40-75% de los pacientes con incontinencia fecal con una prevalencia dos veces mayor en la región anal que en el recto. La neuropatía lumbo-sacra parece ser un mecanismo independiente en la patogenia de la incontinencia fecal, no asocia-do con otras disfunciones sensitivomotoras. La estimulación magnética translumbosacral anorrec-tal tiene un alto rendimiento, es una prueba neurofisiológica segura y clínicamente útil. Consulte Video Resumen en http://links.lww.com/DCR/B728.

Outcomes and Incidence of Complications Following Endoscopic Gastrocnemius Recession: A Systematic Review.

Introduction: Equinus contracture of the ankle can lead to a multitude of foot and ankle pathologies. The gastrocnemius recession has been used to address equinus deformity via various methods, including either an open or an endoscopic approach. Open techniques require increased intraoperative time and complication risks of sural nerve injury, wound complications, and poor cosmesis. Resultantly, the aim of the current study is to review the complications and outcomes of the endoscopic gastrocnemius recession. Methods: A systematic review of electronic databases was performed. The authors compiled data from retrospective and prospective patient studies including general patient demographics, outcomes, qualitative scoring measures, complications, and surgical technique. Results: Eleven studies met our inclusion criteria. A total of 697 feet in 627 patients were included in the current systematic review. The weighted mean age was 45.3 years and weighted mean follow-up was 18.4 months. The most common indication for an endoscopic gastrocnemius recession was equinus contracture. The weighted mean preoperative ankle range of motion was -2.3° and the weighted postoperative ankle range of motion was 10.9°. The most common complications included plantarflexion weakness of the ankle at 3.5%, a sural nerve injury of 3.0% and wound complication rate was 1.0% with no deep infection. The overall complication rate was 7.5%. Conclusion: The endoscopic gastrocnemius recession is a valuable surgical tool in the treatment of ankle equinus. The endoscopic approach has satisfactory outcomes including low incidence of plantarflexion weakness and sural neuritis. Patients should be counseled on these risks preoperatively. Compared with previously reported systematic review of the open technique, the endoscopic approach has a lower overall incidence of complications. Prospective clinical trials comparing open and endoscopic techniques are warranted.Levels of Evidence: Level IV.

Cytokine Levels in Neural Pain in Leprosy.

Pain is a frequent symptom in leprosy patients. It may be predominantly nociceptive, as in neuritis, or neuropathic, due to injury or nerve dysfunction. The differential diagnosis of these two forms of pain is a challenge in clinical practice, especially because it is quite common for a patient to suffer from both types of pain. A better understanding of cytokine profile may serve as a tool in assessing patients and also help to comprehend pathophysiology of leprosy pain. Patients with leprosy and neural pain (n = 22), neuropathic pain (n = 18), neuritis (nociceptive pain) (n = 4), or no pain (n = 17), further to those with diabetic neuropathy and neuropathic pain (n = 17) were recruited at Souza Araujo Out-Patient Unit (Fiocruz, Rio de Janeiro, RJ, Brazil). Serum levels of IL1ß, IL-6, IL-10, IL-17, TNF, CCL-2/MCP-1, IFN-γ, CXCL-10/IP-10, and TGF-ß were evaluated in the different Groups. Impairment in thermal or pain sensitivity was the most frequent clinical finding (95.5%) in leprosy neuropathy patients with and without pain, but less frequent in Diabetic Group (88.2%). Previous reactional episodes have occurred in patients in the leprosy and Pain Group (p = 0.027) more often. Analysis of cytokine levels have demonstrated that the concentrations of IL-1ß, TNF, TGF-ß, and IL-17 in serum samples of patients having leprosy neuropathy in combination with neuropathic or nociceptive pain were higher when compared to the samples of leprosy neuropathy patients without pain. In addition, these cytokine levels were significantly augmented in leprosy patients with neuropathic pain in relation to those with neuropathic pain due to diabetes. IL-1ß levels are an independent variable associated with both types of pain in patients with leprosy neuropathy. IL-6 concentration was increased in both groups with pain. Moreover, CCL-2/MCP-1 and CXCL-10/IP-10 levels were higher in patients with diabetic neuropathy over those with leprosy neuropathy. In brief, IL-1ß is an independent variable related to neuropathic and nociceptive pain in patients with leprosy, and could be an important biomarker for patient follow-up. IL-6 was higher in both groups with pain (leprosy and diabetic patients), and could be a therapeutic target in pain control.

The Impact of Local Steroid Administration on the Incidence of Neuritis following Lumbar Facet Radiofrequency Neurotomy.

BACKGROUND: Pain arising from the lumbar facet joints is a common cause of axial back pain in adults. Radiofrequency neurotomy (RFN) of the medial branches of the spinal dorsal rami has been used as a treatment option. The most common side effect is transient, localized, burning, neuritic-type pain, termed post-neurotomy neuritis (PNN). Corticosteroids have been administered through the radiofrequency cannula after neurotomy to prevent PNN, but no study has examined the effects of this on PNN. OBJECTIVES: We investigated the incidence of PNN in patients who received corticosteroids after RFN and in those patients who did not receive corticosteroids. STUDY DESIGN: Retrospective evaluation. SETTING: Single-site interventional pain management practice in an urban tertiary academic medical center. METHODS: One hundred and sixty-four patients were included in this study and were categorized into non-steroid (n = 87) and steroid (n = 77) groups. Patient's age, gender, body mass index (BMI), laterality of procedure, use of neuropathic pain medications, baseline pain, and duration of pain were all recorded. PNN was determined if the patient self-reported transient burning or neuropathic pain at the site prior to or at the 6-week routine follow-up encounter. RESULTS: There was no significant difference in demographic characteristics between the 2 groups in age, gender, baseline pain, and duration of pain. The proportion of patients in the steroid treated group with PNN was 5 out of 77 (6.4%) and the non-steroid group was 6 out of 87 (6.9%). There was no statistically significant difference between the groups. There was no statistically significant difference in the incidence in neuritis between individuals taking neuropathic agents and individuals not taking neuropathic agents. LIMITATIONS: This study has several limitations including small sample size, patients' self-reported neuropathic symptoms, and inability to draw strong conclusions due to the retrospective study design. A single interventionalist performed all the procedures in this retrospective study and variations in technique amongst others are inevitable. CONCLUSION: Administration of steroids after RFN does not reduce the incidence of post-neurotomy neuritis. Concurrently administering neuropathic medications does not protect against neuritis. KEY WORDS: Radiofrequency neurotomy, radiofrequency ablation, neuritis, corticosteroid, lumbar facet pain, post neurotomy neuritis.

The Effect of Intra-articular Cocktail Versus Femoral Nerve Block for Patients Undergoing Hip Arthroscopy.

PURPOSE: To compare clinical efficacy and complication rate as measured by postoperative falls and development of peripheral neuritis between intra-articular blockade and femoral nerve block in patients undergoing arthroscopic hip surgery. METHODS: An institutional review board approved retrospective review was conducted on a consecutive series of patients who underwent elective arthroscopic hip surgery by a single surgeon, between November 2013 and April 2015. Subjects were stratified into 2 groups: patients who received a preoperative femoral nerve block for perioperative pain control, and patients who received an intra-articular "cocktail" injection postoperatively. Demographic data, perioperative pain scores, narcotic consumption, incidence of falls, and iatrogenic peripheral neuritis were collected for analysis. Postoperative data were then collected at routine clinical visits. RESULTS: A total of 193 patients were included in this study (65 males, 125 females). Of them, 105 patients received preoperative femoral nerve blocks and 88 patients received an intraoperative intra-articular "cocktail." There were no significant differences in patient demographics, history of chronic pain (P = .35), worker's compensation (P = .24), preoperative pain scores (P = .69), or intraoperative doses of narcotics (P = .40). Patients who received preoperative femoral nerve blocks reported decreased pain during their time in PACU (P = .0001) and on hospital discharge (P = .28); however, there were no statistically significant differences in patient-reported pain scores at postoperative weeks 1 (P = .34), 3 (P = .64), and 6 (P = .70). Administration of an intra-articular block was associated with a significant reduction in the rate of postoperative falls (P = .009) and iatrogenic peripheral neuritis (P = .0001). CONCLUSIONS: Preoperative femoral nerve blocks are associated with decreased immediate postoperative pain, whereas intraoperative intra-articular anesthetic injections provide effective postoperative pain control in patients undergoing arthroscopic hip surgery and result in a significant reduction in the rate of postoperative falls and iatrogenic peripheral neuritis. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

Leprosy reactions in postelimination stage: the Bangladesh experience.

BACKGROUND: Leprosy reactions are immunologically mediated conditions and a major cause of disability before, during and after multidrug therapy (MDT). Little data have been published on the epidemiology of leprosy reactions in Bangladesh. OBJECTIVES: To describe the pattern and prevalence of leprosy reactions in the postelimination stage. METHODS: A descriptive retrospective cross-sectional study was carried out in Chittagong Medical College Hospital using the registered records of patients in the period between 2004 and 2013. RESULTS: Of the 670 patients with leprosy, 488 (73.38%) were males and 182 (27.37%) were females. The prevalence of reaction was in 300 (44.78%) patients with a male:female ratio of 3.55 : 1. The age-specific cumulative reaction cases at >40 years were 115 (38.33%) among all age groups. The prevalence of reaction was found to be in 166 (55.33%) patients for the reversal reaction, 49 (16.57%) for the erythema nodosum leprosum (ENL) and 85 (28.33%) for the neuritis. Borderline tuberculoid was most common (106, 35.33%)in the reversal reaction group, while lepromatous leprosy was most common (37, 12.33%) in ENL group. More than half of the patients (169, 56.33%) had reactions at the time of presentations, while 85 (28.33%) and 46 (15.33%) patients developed reaction during and after MDT, respectively. The reversal reaction group presented with ≥six skin lesions in 96 (57.83%) patients and ≥two nerve function impairments (NFIs) in 107 (64.46%) patients. The ENL was present chiefly as papulo-nodular lesions in 45 (91.84%) patients followed by pustule-necrotic lesions in four (8.16%), neuritis in 33 (67.35%), fever in 24 (48.98%), lymphadenitis in six (12.24%), arthritis in five (10.20%) and iritis in two (4.08%). Bacterial index ≥3 had been demonstrated in 34 (60.71%) patients in ENL group. CONCLUSION: The incidence of leprosy reaction seemed to be more than three times common in borderline tuberculoid (52.33%) group than in lepromatous leprosy (14%) group. Reactions with NFI and disability still occur among multibacillary patients during and after MDT. Early detection and management of leprosy reaction are very important in preventing disability and deformity, and patients should be educated to undergo regular follow-up examinations. Developing reinforced new therapies to curb leprosy reactions is crucial for improving leprosy healthcare services.

Ventriculoatrial Shunts in Adults, Incidence of Infection, and Significant Risk Factors: A Single-Center Experience.

BACKGROUND: In recent years, the number of ventriculoatrial (VA) shunt insertions has decreased worldwide, the major cause being the risk of shunt infection. VA shunts remain as an alternative option to ventriculoperitoneal shunts. We describe our 10-year experience with VA shunts by analyzing the incidence of shunt infections and predisposing cofactors. METHODS: During a median follow-up of 15.3 months, 259 shunt insertions, performed on 255 patients, were analyzed. The infection rate was calculated and the predisposing cofactors age, gender, cause of the hydrocephalus, previous external ventricle drainage, antibiotic-impregnated catheters, the number of revisions, the educational level of the surgeons, and the duration of the operations were analyzed. Two observation times were stratified. RESULTS: We found overall infections in 18 patients (7.1%), 16 deep infections (6.3%) including 1 shunt nephritis (0.4%) and 2 superficial infections (0.8%). Wound dehiscence occurred in 17 patients (6. 6%). Analyzing follow-up time, the infection rate was 3.65% (95% confidence interval, 0.9%-5.9%) at survival time 1, 3.38% (95% confidence interval, 1.1%-6.2%) at survival time 2. In the first 6 months, 95% of patients were free of infection. Only the number of revision procedures was associated with the number of infections (P value < 0.0005). CONCLUSIONS: In our patient cohort, the infection rate related to VA shunt insertion is low; the only statistically significant risk factor was the number of revisions. If the VA shunt is applied following a standardized protocol, the infection risk does not represent an argument for reluctance towards the VA draining concept.

Pure neuritic leprosy: Current status and relevance.

Pure neuritic leprosy has always been an enigma due to its clinical and management ambiguities. Although only the Indian Association of Leprologist's classification recognizes 'pure neuritic leprosy' as a distinct sub group of leprosy, cases nonetheless are reported from various countries of Asia, Africa, South America and Europe, indicating its global relevance. It is important to maintain pure neuritic leprosy as a subgroup as it constitutes a good percentage of leprosy cases reported from India, which contributes to more than half of global leprosy numbers. Unfortunately, a high proportion of these patients present with Grade 2 disability at the time of initial reporting itself due to the early nerve involvement. Although skin lesions are absent by definition, when skin biopsies were performed from the skin along the distribution of the affected nerve, a proportion of patients demonstrated leprosy pathology, revealing sub-clinical skin involvement. In addition on follow-up, skin lesions are noted to develop in up to 20% of pure neuritic leprosy cases, indicating its progression to manifest cutaneous disease. Over the decades, the confirmation of diagnosis of pure neuritic leprosy has been subjective, however, with the arrival and use of high-resolution ultrasonography (HRUS) for nerve imaging, we have a tool not only to objectively measure and record the nerve thickening but also to assess the morphological alterations in the nerve including echo texture, fascicular pattern and vascularity. Management of pure neuritic leprosy requires multidrug therapy along with appropriate dose of systemic corticosteroids, for both acute and silent neuritis. Measures for pain relief, self-care of limbs and physiotherapy are important to prevent as well as manage disabilities in this group of patients.

Air pollution, a rising environmental risk factor for cognition, neuroinflammation and neurodegeneration: The clinical impact on children and beyond.

Air pollution (indoors and outdoors) is a major issue in public health as epidemiological studies have highlighted its numerous detrimental health consequences (notably, respiratory and cardiovascular pathological conditions). Over the past 15 years, air pollution has also been considered a potent environmental risk factor for neurological diseases and neuropathology. This review examines the impact of air pollution on children's brain development and the clinical, cognitive, brain structural and metabolic consequences. Long-term potential consequences for adults' brains and the effects on multiple sclerosis (MS) are also discussed. One challenge is to assess the effects of lifetime exposures to outdoor and indoor environmental pollutants, including occupational exposures: how much, for how long and what type. Diffuse neuroinflammation, damage to the neurovascular unit, and the production of autoantibodies to neural and tight-junction proteins are worrisome findings in children chronically exposed to concentrations above the current standards for ozone and fine particulate matter (PM2.5), and may constitute significant risk factors for the development of Alzheimer's disease later in life. Finally, data supporting the role of air pollution as a risk factor for MS are reviewed, focusing on the effects of PM10 and nitrogen oxides.

A critical appraisal on pure neuritic leprosy from India after achieving WHO global target of leprosy elimination.

Background: Clinical data on pure-neuritic leprosy (PNL) is limited. Objective: To study the clinical and epidemiological features of PNL in the leprosy post-elimination era. Methods: This was a retrospective analysis of the clinic records of leprosy patients from January 2006 to June 2013. Data regarding age, sex, disease duration, presenting complaints, nerves affected, complications and treatment received were extracted from PNL cases. Results: Among 906 registered leprosy cases, 48 (5·3%) were found to have PNL. The mean age was 36·9 ± 16·2 years and predominantly males were affected (85·4%). The mean delay between onset of symptoms and diagnosis was 2·1 ± 2·2 years. Multiple nerves were affected in 36 patients (75%) and 12 (25%) had only one nerve involved. Visible deformities at presentation were noted in 32 (66·7%) patients. Forty patients (83·3%) were treated with multi drug therapy-multibacillary (MDTMB) regimen and three (6·25%) were treated with MDT-paucibacillary regimen. Twenty-one patients (43·8%) were considered positive responders to treatment. There was no correlation between the duration of NFI and treatment outcome. Conclusion: PNL continues to occur in the post-elimination era. Grade 2 deformities are common in PNL compared to other leprosy patients because of delayed diagnosis and treatment. Distinct diagnosis and treatment guidelines and sensitisation of health care workers and physicians to the occurrence of PNL is the need of the day.

Self-awareness of foot health status in patients with Type 2 diabetes: the Fremantle Diabetes Study Phase II.

AIMS: To determine self-awareness of diabetes-related foot problems and its associates in a community-based cohort of people with Type 2 diabetes. METHODS: A survey concerning diabetic foot problems was administered to 358 consecutive patients with Type 2 diabetes [mean ± SD age 67.4 ± 10.8 years, 56.1% males, median (interquartile range) diabetes duration 9.0 (3.9-16.8) years] attending for detailed clinical, biochemical and questionnaire assessment as part of the longitudinal observational Fremantle Diabetes Study Phase II. RESULTS: Compared with the 213 patients (59.5%) who considered their feet to be normal, the 145 (40.5%) who considered their feet to be abnormal were older, had longer diabetes duration and were more likely to have sensory neuropathic symptoms and self-reported poor circulation (P < 0.001). In those who considered their feet to be normal, 67.9% had peripheral sensory neuropathy (score >2/8 on the Michigan Neuropathy Screening Instrument clinical portion), 9.9% had an ankle-brachial index < 0.9, 6.1% had both peripheral sensory neuropathy and an ankle-brachial index < 0.90, and 86.9% had one or more features on inspection, such as deformity, dry skin, callus and fissures that could facilitate more serious complications, despite the majority having had at least one foot examination by a healthcare professional in the previous year. CONCLUSIONS: Self-assessment of diabetes-related foot problems by patients in the Fremantle Diabetes Study Phase II was unreliable. The present data suggest that self-perceived foot health should be assessed together with foot examination findings. Intensive education and monitoring may be necessary in those who consider their feet to be normal but who have neurovascular, structural and/or other precursors of serious foot pathology.

Does the diabetic foot have a significant impact on selected psychological or social characteristics of patients with diabetes mellitus?

UNLABELLED: The aim of our case-control study was to compare selected psychological and social characteristics between diabetic patients with and without the DF (controls). METHODS: 104 patients with and 48 without DF were included into our study. Both study groups were compared in terms of selected psychosocial characteristics. RESULTS: Compared to controls, patients with DF had a significantly worse quality of life in the area of health and standard of living as shown by lower physical health domain (12.7 ± 2.8 versus 14.7 ± 2.5; P < 0.001) and environment domain (14.1 ± 2.2 versus 15 ± 1.8; P < 0.01) that negatively correlated with diabetes duration (r = -0.061; P = 0.003). Patients with DF subjectively felt more depressed in contrast to controls (24.5 versus 7.3%; P < 0.05); however, the depressive tuning was objectively proven in higher percentage in both study groups (83.2 versus 89.6; NS). We observed a significantly lower level of achieved education (P < 0.01), more patients with disability pensions (P < 0.01), and low self-support (P < 0.001) in patients with the DF compared to controls. In the subgroup of patients with a previous major amputation and DF (n = 6), there were significantly worse outcomes as in the environment domain (P < 0.01), employment status, and stress readaptation (P < 0.01) in contrast to the main study groups. CONCLUSIONS: Patients with DF had a predominantly worse standard of living. In contrast to our expectations, patients with DF appeared to have good stress tolerability and mental health (with the exception of patients with previous major amputation) and did not reveal severe forms of depression or any associated consequences.

Pure neuritic leprosy in patients from a high endemic region of Colombia.

Agua de Dios was a leprosarium for leprosy patients' obligatory isolation (1872-1961). Its leprosy incidence is the highest in Colombia (1.5-7/10000). Relapses are common. Government grant of US$ 200 per month subsidy is available to patients with disabilities. Spontaneous consultation with neural symptoms is frequent and simulation to get the subsidy has to be considered. We studied 36 subjects (2007-2009), with ages from 29-78, 19 of them men, with neural symptoms of 6 months to 20 years evolution. All had clinical examination, bacteriological examination, skin and nerve biopsies, electromyography (EMG), PCR for M. leprae, IgM anti-PGL1, and lepromin A. All but two are household contacts of leprosy patients. Symptoms were hypoesthesia of the hands and feet, and difficulty using hands with loss of muscular strength. None had skin lesions. Three had thickening of ulnar nerve. Lepromin was positive in all; bacteriology and biopsies were negative in all. The speed and amplitude of neural conduction were altered in 34 patients; two women had normal EMG and were considered to be feigning the disease; 21 were diagnosed as PNL by clinical, epidemiological and EMG findings; five of them had a positive PCR and one, high titers for IgM anti PGL1. Nine other subjects had diabetes and six carpal tunnel syndrome (CTS). Slow progression of disease, the lack of neural enlargement and the neural biopsies without inflammation suggest that most of these patients could have spontaneously cured PNL, as happens with other cases of paucibacillary leprosy. Diabetes and CTS are important differential diagnoses of PNL. Patients were treated with MDT and received the state subsidy.

Diabetic neuropathy part 1: overview and symmetric phenotypes.

Diabetes is the most common cause of neuropathy in United States and neuropathies are the most common complication of diabetes mellitus, affecting up to 50% of patients with type 1 and type 2 diabetes mellitus. Symptoms usually include numbness, tingling, pain, and weakness. Dizziness with postural changes can be seen with autonomic neuropathy. Metabolic, vascular, and immune theories have been proposed for the pathogenesis of diabetic neuropathy. Axonal damage and segmental demyelination can be seen with diabetic neuropathies. Management of diabetic neuropathy should begin at the initial diagnosis of diabetes and mainly requires tight and stable glycemic control.

Disability among new leprosy patients, an issue of concern: an institution based study in an endemic district for leprosy in the state of West Bengal, India.

BACKGROUND: Both magnitude and severity of disability in new leprosy patients measure indirectly the disease transmission in the community and rapidity of case detection. Various factors might be associated with the presence of impairment at registration. AIMS: To find out the prevalence of both grade 1 and grade 2 disability among new leprosy patients along with association of some clinical and sociodemographic factors. METHODS: A cross-sectional study was carried out in the Skin out patient department (OPD) of a Tertiary care hospital in West Bengal, which is situated in a highly endemic district of leprosy (prevalence was 6.5/10,000, year 2007). About 244 new leprosy patients were interviewed and clinically examined during Aug'06-Jun'07. Data was analysed in percentages, χ2 test, Anova. RESULTS: Proportion of disability was quite high among the studied new leprosy patients, 11.5% had grade-1 and 8.6% had grade-2. Disability was more among the patients with pure neuritic type of leprosy (<0.001), multibacillary leprosy (P=0.000), patients with delayed registration (P=0.000) and who were engaged as manual laborers (P=0.001). Feet were commonly involved site and nerve function impairment, both sensory and motor were the commonest nature of disability found in this study. CONCLUSION: To reduce new leprosy cases with grade-2 disability, early diagnosis of the leprosy patients and searching for grade-1 disability should be routine procedure in our health system, for which thorough neurological examination along with appropriate preventive measures is the need of the hour.

Primary results of clinical trial for uniform multidrug therapy for leprosy patients in Brazil (U-MDT/CT-BR): reactions frequency in multibacillary patients.

SETTINGS: Many believe that the regular treatment for multibacillary (MB) leprosy cases could be shortened. A shorter treatment, allowing for uniform treatment for all cases, makes case classification superfluous and therefore simplifies leprosy control. OBJECTIVE: To evaluate the association of the treatment duration with the frequency of reactions among MB patients. METHODS: An open-label randomised clinical trial to compare the present routine treatment with one lasting six months. Patients were recruited between March 2007 and February 2012. We analysed the frequency of first reaction with the Kaplan-Meier method and of recurrent reaction with a Poisson regression, using the treatment group and baciloscopic index level (BI) as independent variables. Logistic regression was used to evaluate the statistical association of different reaction types and the treatment group. RESULTS: Among those with BI < 3, we found a statistical significant difference of reaction frequencies between the treatment groups from 6 to 18 months since the beginning of treatment. This difference disappears at 2 years after the start of treatment. Multiple reactions were associated with the treatment group and with BI > or = 3. No specific types of reactions were associated with treatment duration. CONCLUSION: Although this is the first report of U-MDT/CT-BR, the results presented here support the possibility of use of UMDT in the field.

Neural damage associated with atopic diathesis: a nationwide survey in Japan.

BACKGROUND: We previously reported the occurrence of myelitis in patients with atopic disorders (atopic myelitis [AM]). To uncover the spectrum of neural damage associated with atopy, we conducted a cross-sectional nationwide survey of AM and atopy-related peripheral neuritis (APN), including Churg-Strauss syndrome (CSS), in individuals with atopic diathesis. METHOD: Cases with AM diagnosed between 1996 and 2006 and cases with APN between 2000 and 2006 were collected from all over Japan. Detailed data on 109 patients with AM and 133 patients with APN were collated. RESULTS: Patients with APN showed a preponderance of women, higher age at onset, and greater eosinophil counts than patients with AM. Patients with AM most commonly showed cervical cord involvement, whereas patients with APN preferentially exhibited mononeuritis multiplex predominantly affecting the lower limbs. Among patients with AM, motor weakness and muscle atrophy were significantly more frequent in those with bronchial asthma than in those with other atopic disorders. Patients with APN who met the criteria for CSS showed a higher age at onset, higher frequencies of systemic organ involvement, and greater disability than those who did not. Abnormalities suggesting peripheral nervous system involvement were seen in 25.7% of patients with AM, whereas 18.8% of patients with APN had abnormalities indicating CNS involvement. Multiple logistic regression analyses revealed that atopic dermatitis increased the risk of myelitis, whereas high age at onset and bronchial asthma decreased that risk. CONCLUSIONS: Atopy-related neural inflammation multifocally affects CNS and peripheral nervous system tissues. Both preceding atopic disorders and age seem to influence the distribution of neural damage.
