[Late sequelae of violence seen from victims' perspective].

Hospital accident and emergency (A&E) departments frequently treat victims of interpersonal violence. This study of 1,451 victims treated at the A&E departments of Aarhus University Hospital during a one-year period (1993-94) aims at illuminating some of the sequelae of victims. A questionnaire survey was carried out two years later to obtain information on medical after-treatment, the extent of sick leaves, and the victims' personal costs. One in two assault victims needed further medical treatment. 7.5% were admitted to hospital and 20% were referred to the out-patient clinic in the hospital or to follow-up treatment in general practice. The median sick leave period was eight days. Two years after the violence took place, 21.8% of all assault victims claimed that they had cosmetic sequelae, 14.7% had persistent pain. 38.1% said they were afraid to enter certain neighbourhoods or places; 41.2% had frequently or occasionally thought about the assault. The study has revealed some aspects of the personal costs, discomfort and trouble that victims of violence experience.

[Late sequelae of early summer meningoencephalitis].

The incidence of tick-borne encephalitis varies widely in different geographic regions due to local difference in the rate of infected vectors (Ixodes ricinus) transmitting tick-borne encephalitis virus. In the Cantonal Hospital Winterthur a large number of cases are hospitalised due to endemic areas with infected ticks nearby. From 1976 until 1996 132 patients with tick-borne encephalitis were hospitalised (an average of 7 patients per year), compared with 535 cases (41 per year) in the whole of Switzerland during a similar period (1984-1992). While previously tick-borne encephalitis was considered to be a harmless illness with complete recovery, a postencephalitic syndrome after tick-borne encephalitis has recently been reported. Since the prevalence of sequelae differs in these publications, the aim of this study was to investigate sequelae in a Swiss population which had suffered from tick-borne encephalitis. We retrospectively analysed the patients with tick-borne encephalitis hospitalised in the years 1987-1996, to determine the clinical and functional outcome. A few weeks after discharge from hospital, 73% patients still had complaints, and one year later 56%. 32 patients were observed over 5 years and 31% still had some disability. After tick-borne encephalitis 10% of patients did not recover the same quality of life as before. The symptoms most frequently reported were fatigue, concentration deficits and impairment of memory. Objective neurological deficits were rare. Our results correspond well with experience in other countries and demonstrate the substantial morbidity of tick-borne encephalitis. We recommend therefore vaccination against tick-borne encephalitis, an effective measure with a low complication rate.

[Prevention of sequelae after transcutaneous radiotherapy for epitheliomas of the oral cavity (author's transl)].

Close cooperation between the radiotherapist, surgeon, and patient is necessary in order to prevent sequelae following transcutaneous radiotherapy for epitheliomas of the oral cavity. The most effective therapeutic results combined with a minimum of sequelae are obtained by the use of a good irradiation technique, close supervision, careful treatment of any oral or dental affection, prescribing simple medications only, and stopping the use of tobacco and alcohol.

Cranial MR imaging of sequelae of prefrontal lobotomy.

BACKGROUND AND PURPOSE: Although prefrontal lobotomy is an obsolete treatment for schizophrenia, we still encounter patients who have undergone this procedure. The purpose of this study was to describe the MR imaging findings of sequelae of prefrontal lobotomy. METHODS: We retrospectively reviewed cranial MR images of eight patients with schizophrenia who underwent prefrontal lobotomy approximately 50 years previously. RESULTS: In all patients, a bilateral cavitary lesion with a thick wall was found in the frontal white matter. The genu of the corpus callosum was mildly to markedly atrophic. The size and location of the cavity and the degree of callosal atrophy were correlated. CONCLUSION: MR imaging is useful for the diagnosis of sequelae of prefrontal lobotomy, including cavitary lesions with dense walls of gliosis and secondary degeneration of the genu of the corpus callosum.

[Extrapontine myelinolyses caused by iatrogenic hypernatremia following rupture of a hydatid cyst of the liver with an amnesic syndrome as sequela].

INTRODUCTION: Extrapontine myelinolisis is a rare condition caused by severe hydroelectrolytic disorders. Following an initial stage of diffuse encephalopathy, the neurological sequelae are usually of diffuse cognitive deficits and extrapyramidal or cortico-bulbo-spinal disorders. We report a case of extrapontine myelinolisis following hypertonic peritoneal lavage due to rupture of a hydatid cyst of the liver (HCL), which was followed by a syndrome of isolated amnesia due to bilateral hippocampal lesions. CLINICAL CASE: Following rupture of a HCL a 37 year old man was treated by peritoneal lavage with hypertonic saline solution. In the immediate postoperative period he had a prolonged confusion state associated with natremia of 176 mg/dl, which was corrected in less than 24 hours. Seven days later the patient had an apathy-inattention frontal syndrome. Six weeks later, and lasting until three months after operation, he had a selective memory deficit in learning tests (of the Barcelona-PIENC series of tests) with normality (29/30) in the MMST. On magnetic resonance there were hyperintense images in T2 in both hippocampus, insulas and corpus callosum. CONCLUSIONS: Generally caused by rapidly corrected hyponatremia, isolated hyponatremia or hypernatremia may also lead to extrapontine myelinolisis. However, we have found no report of extrapontine myelinolisis due to rupture of HCL and treatment with hypertonic peritoneal lavage. The neurological sequelae of extrapontine myelinolisis are usually global cognitive deficits, extra-pyramidal or cortico-bulbo-spinal disorders. Lesions seen on MR are usually found in the basal ganglia, thalamus or corpus callosum (with or without involvement of the pons). We have found no descriptions of bilateral hippocampal lesions causing selective memory deficits in this condition. Treatment by hypertonic peritoneal lavage for ruptured HCL may cause severe hydro-electrolytic alterations which may lead to myelinolisis of the CNS. We report of a case with bilateral hippocampal lesions and selective memory deficit, not previously described within the clinical spectrum of extrapontine myelinolisis.

Intrusion injuries of primary incisors. Part II: Sequelae affecting the intruded primary incisors.

Luxation injuries to incisors, including intrusive displacement, occur with a high frequency in the primary dentition. Intrusion injuries are associated with damage to the pulpal and periodontal structures and possible fracture of the alveolar bone. The pulpal tissue of the intruded tooth sustains a severe shock during displacement, which may be reflected later by sequelae ranging from mild discoloration to pulpal necrosis and infection. Disintegration of pulpal tissue may result in periapical tissue inflammation, which in turn may induce developmental disturbances in the germ of the permanent successor tooth. Additionally, severe injury to the periodontal ligament during intrusion may lead to ankylosis of the primary incisor and consequently to delayed or ectopic eruption of its permanent successor. This article will review the possible sequelae affecting primary incisors following their intrusion.

[Long and medium-term neuropsychological sequelae of bone marrow transplantation in pediatric patients with hematological disease].

BACKGROUND: Few studies exist on the neuropsychological sequelae of bone marrow transplantation (BMT) in pediatric patients. Published results show considerable discrepancies although studies of children with acute lymphoblastic leukemia undergoing high doses of cranial radiotherapy report short- and long-term loss of cognitive ability. OBJECTIVES: To determine the effects of BMT and the effect of anxiety on the pre-BMT assessment in a group of children with severe hematological disease treated in our center. METHODS: We performed a descriptive, prospective, longitudinal study of 54 children, aged 4-15 years, who were treated between 1987 and 1995. Twenty-two children were evaluated before and after BMT by means of the Weschler Intelligence Scale. To control for the effect of anxiety on the pre-BMT scores, the patients were divided into two groups according to the scores obtained in this test (group 1: IQ score 100; group 1: IQ100). RESULTS: Comparison of pre- and post-BMT scores for both groups revealed no significant differences. However, comparison of the results between groups revealed that group I scored lower in the post-BMT test than in the pre-BMT test while group I scored higher in the post-BMT test than in the pre-BMT test. CONCLUSIONS: Although comparison between the pre- and post-BMT results obtained from the whole sample showed no differences that indicated post-treatment sequelae, treatment-induced anxiety may have influenced the pre-BMT score.

Interobserver reproducibility in reporting on 99mTc-DMSA scintigraphy for detection of late renal sequelae.

UNLABELLED: This study was designed to evaluate the interobserver variability in reporting on 99mTc-dimercaptosuccinic acid (DMSA) scanning performed 6 mo after an acute episode of pyelonephritis for the detection of late renal sequelae. METHODS: Forty-six children were selected, who had early and late DMSA studies for evaluation of acute pyelonephritic lesions as well as sequelae. Three observers reported independently and separately on the early and late DMSA scans and, in a second step, on the late scan in the presence of the early scan. Interobserver reproducibility was evaluated for the early DMSA scan, the late DMSA scan alone, and the late DMSA scan with the early scan for comparison. RESULTS: Complete agreement between the three observers was reached in 75%, 78%, and 77% for the early DMSA scan, the late DMSA scan alone, and the late DMSA scan with the early scan for comparison, respectively. CONCLUSION: Interobserver reproducibility was high and was comparable for both early and late DMSA scintigraphy.

Projecting severe sequelae of injection-related hepatitis C virus epidemic in the UK. Part 1: Critical hepatitis C and injector data.

BACKGROUND: Hepatitis C is transmitted by transfusion of unscreened blood, through injecting drugs, from mother-to-child and, on occasion, sexually. Transmission generally requires that the infector is hepatitis C virus (HCV) RNA positive, a 'carrier'. About three-quarters of injectors who are hepatitis C antibody positive are HCV-RNA positive and so infectious to others. Incubation periods from HCV infection to cirrhosis and hepatocellular carcinoma are even longer than from HIV infection to AIDS, being counted in decades; they depend on age, gender, alcohol consumption and co-infection with other viruses. We identify 25 data sources that are available, or required, for projecting the severe sequelae of the injection-related hepatitis C epidemic. DATA SOURCES: Three data sources relate to hepatitis C diagnosis: register of confirmed HCV infections (with initial of first name + soundex of surname + date of birth + gender = master index, exposure category, year of starting to inject, and region); surveys of HCV test-uptake by injectors and others; documentation of pregnancy and its outcome in HCV-infected women (injectors and others). Four data sources relate to HCV prevalence and incidence among injectors and others: anonymous testing for HCV antibodies in blood or saliva (for sentinel groups ranging from new blood donors, pregnant women, patients awaiting kidney transplantation, non-injector prisoners, health-care workers, non-injector heterosexuals attending genitourinary medicine clinics; to injectors in the community, at drug treatment centres or in prison); historical data on HCV prevalence in injectors; HCV incidence studies in injectors; and uptake of harm reduction measures--frequency of sharing and methadone substitution--by injectors. Key reporting problems in HCV incidence studies, which inhibit checks on the convenient exponential assumption for time from start of injecting to hepatitis C infection, are discussed. Nine critical data sources are identified for monitoring the late sequelae of hepatitis C carriage, its investigation and treatment: linkage surveillance, for example by master index, to identify deaths, hospitalisations or cancer registrations among confirmed HCV infections; surveys of HCV status among patients who undergo liver biopsy, are newly diagnosed with cirrhosis or are newly diagnosed with liver cancer; surveys of liver-biopsy rate in HCV-infected injectors and others; uptake and outcome of interferon + ribavirin in the treatment of hepatitis C carriers; cohort studies of HCV progression; sample surveys of genotype in HCV-infected injectors, and others; acute hepatitis B infections and uptake of hepatitis B immunisation by injectors; liver transplantation in HCV-infected patients; and hepatitis C-status and other risk factors in deaths from cirrhosis or liver cancer, to determine whether they are HCV and injector-related. Finally, nine critical data sources are identified for quantitative understanding of the underlying injector epidemic: drug misuse databases plus capture-recapture methods to assess number of injectors, drug-related deaths by region to assess injector numbers; number of HIV-infected injectors; HIV progression in injectors; overdose and other causes of death in injectors; expert opinion on injector incidence historically, plus survey information on age-distribution at initiation and duration of injector careers; injector incidence historically inferred from hepatitis C infected blood donors; age-distribution of current injectors and at initiation, as a check on the assumptions made in stochastic simulation about injector incidence and 'outcidence' from injecting historically; mortality of former injectors; and general population or other survey ratios of surviving ever-injectors to injectors in the last 5 years, last year and currently, as a check on simulations. RECOMMENDATIONS: We recommend a common HCV diagnosis report form to improve ascertainment of risk-factor information, especially year of starting to inject--which is a key date epidemiologically. We also recommend updated surveys of current and former injectors' HCV-test uptake, or a denominator study that registers master index and risk factor information for all HCV testees. We recommend that injector surveys ask about typical frequency of needle sharing per 4 weeks in three distinct periods this year, last year and in the first year of injecting. We also recommend the location of stored historical samples from injectors to be tested retrospectively and anonymously for HCV antibodies. We recommend immediate attention to the uptake of, and response to, combination treatment by hepatitis C carriers who are former or recovering injectors. We rec

Projecting severe sequelae of injection-related hepatitis C virus epidemic in the UK. Part 2: Preliminary UK estimates of prevalent injection-related hepatitis C carriers, and derivation of progression rates to liver cirrhosis by gender and age at hepatitis C virus infection.

BACKGROUND: In Part 2, we illustrate how available data can be used to obtain preliminary estimates for Scotland of prevalent injection-related hepatitis C carriers and of maternally hepatitis C virus (HCV)-infected infants. Novel approaches to reducing uncertainty about the number of Scotland's HCV infected children of injector parents are discussed in brief. Three approaches, one direct and two indirect, to estimating the number of current and ever-injectors are presented for England and Wales. METHODS: Diagnosed HCV infections in injectors and HCV test uptake by current injectors are combined with survey estimates for the ratio of ever-injectors to current injectors to estimate prevalent injection-related hepatitis C carriers. Household surveys give direct but potentially biased estimates of the number of current and ever-injectors. Indirect estimates make use of hepatitis C diagnoses in injectors, HCV prevalence and test-uptake by injectors, or exploit international comparisons. We comment on key reporting problems that inhibit synthesis of HCV progression studies; and suggest how to derive preliminary gender-and-age specific progression rates to liver cirrhosis for use in projections. RESULTS: Preliminary estimates for Scotland of prevalent injection-related hepatitis C carriers are: central estimate 39,000, inner uncertainty 16,000-59,000; of maternally hepatitis C virus (HCV)-infected infants central estimate 260, uncertainty 110-1100; and for England and Wales estimates of the number of prevalent ever-injectors are central estimate 360,000, uncertainty 240,000-835,000. Both hepatitis C prevalence in injectors and estimated numbers of current injectors are similar in Australia, and England and Wales (but not so for Scotland), Australian work on projections of severe HCV sequelae from hepatitis C infections may therefore be a suitable starting point for projections for England and Wales. Australia anticipates a doubling in the number of persons living with hepatitis C cirrhosis from 8500 in 1997 to over 17,000 in 2010. DISCUSSION: Australian projections of severe HCV sequelae used progression rates that, for simplicity, were independent of gender and of age at HCV infection. Faster HCV progression for males, and their higher injector prevalence, means that the impact of HCV infection on, for example, liver cancer may be evident to a greater extent and earlier in males.

Auditory and vestibular sequelae to traumatic brain injury: a pilot study.

AIM: To investigate the incidence of persisting auditory and vestibular sequelae in a group of 30 young adults recovering from Traumatic Brain Injury (TBI). METHODS: 30 participants, aged 21-45 years, with TBI suffered 19 months to 27 years previously, underwent a semi-structured interview and pure-tone hearing test in their home. Participants who failed the hearing screen then undertook a more comprehensive audiological evaluation. RESULTS: A variety of sequelae to TBI were reported. These were interpreted as tinnitus (53%), vestibular dysfunction (83%), abnormal facial sensory symptoms (27%) and intolerance to loud/sudden noises (87%). Ten (33%) participants demonstrated significant sensorineural hearing impairment in addition to speech recognition performance significantly worse than would have been predicted from their hearing impairment. CONCLUSIONS: Findings from this study will be of benefit to health professionals working in this area of rehabilitation as they seek to provide functional assessments and devise programmes to treat the often devastating auditory processing problems of people recovering from TBI.

Hyperbaric oxygen for carbon monoxide poisoning-induced delayed neuropsychiatric sequelae.

The clinical manifestations of delayed neuropsychiatric sequelae after carbon monoxide (CO) intoxication are variable. In addition, there is no specific therapy for these complications. Fortunately, these complications have occurred less frequently in recent years, probably due to the usage of hyperbaric oxygen (HBO) therapy. We report an 8-year-old boy who developed late psychiatric disturbances 2 days after full recovery of consciousness from initial CO intoxication. His neuropsychiatric symptoms included consciousness disturbance, motor dysfunction, chorea, aphasia and agnosias. He received HBO therapy at 2.0 barr for 60 minutes once a day for 7 consecutive days. Three weeks later, he was functioning normally with no neuropsychiatric symptoms. A literature review concluded that HBO may be effective in treating neuropsychiatric sequelae. Moreover, immediate administration of HBO during acute CO intoxication may prevent these complications.

Treatment of the sequelae of primary pathology of the hip by correction osteotomy and femoral lengthening using a combined external fixator.

It is not an exceptional event to observe the sequelae of primary pathology of the hip in young patients that, as such, are not of the ideal age for replacement surgery. Moreover, one must not overlook the difficulties involved in replacement surgery for the treatment of inveterate modifications in the normal hip anatomy. Often, among the sequelae of primary pathology of the hip, deformities of the lower limb must also be included, associated or consequent, which also need treatment. For these reasons, the authors, in three selected cases, used a combined external fixator (circular and lateral) by means of which they were at the same time able to correct the axial deformity (with a support osteotomy), and the residual hypometria (with femoral lengthening). Osteotomy plus lengthening, using an external fixator, avoid hypometria of the limb and deformity in valgus of the knee, and allow for results which would otherwise not be obtained with replacement surgery alone.

Harvard Trauma Questionnaire Urdu translation: the only cross-culturally validated screening instrument for the assessment of trauma and torture and their sequelae.

Violence is on the increase all over the world. The method, manner and quantum of such actions remain little explored. The common man has clearly received the message of power through the barrel of a gun. In Pakistan the major battle field of ethnic, political, sectarian and communal conflicts was Sindh and Punjab. Trauma and torture leaves a permanent scar on the survivor. It has physical, psychological and social sequelae. The two major psychiatric illnesses associated with trauma and torture are your major Depression and post traumatic stress disorder. The Harvard Trauma Questionnaire (HTQ) measures symptoms associated with diagnostic criteria for post-traumatic stress disorder as defined by DSMIII R manual and symptoms. Obtaining accurate knowledge of traumatic event and symptoms and properly classifying them into a diagnostic system is fundamental for providing effective treatment and good therapeutic intervention. Therefore an attempt is made to translate the HTQ, the only cross-culturally validated screening instrument for the assessment of trauma and torture related to mass violence and their sequelae [corrected].

Opsoclonus-ataxia caused by childhood neuroblastoma: developmental and neurologic sequelae.

OBJECTIVE: Opsoclonus-ataxia, also called "dancing eye syndrome," is a serious neurologic condition that is often a paraneoplastic manifestation of occult neuroblastoma in early childhood. Despite resection of tumor and immunosuppressive therapy, outcome generally includes significant developmental and behavioral sequelae. There is controversy about how treatment alters outcome. The goals of this study were to understand the ongoing neurologic and developmental deficits of children who are treated for opsoclonus-ataxia with associated neuroblastoma; to relate treatment history to outcome; and to quantify objectively the acute changes in motor function, speech, mood, and behavior related to intravenous immunoglobulin (IVIg) treatment. METHODS: Patients were children with opsoclonus-ataxia caused by neuroblastoma, regardless of interval since diagnosis. Records were reviewed, and children underwent comprehensive evaluations, including neurologic examination and tests of cognitive and adaptive function, speech and language, and fine and gross motor abilities. Psychiatric interview and questionnaires were used to assess current and previous behavior. In 6 children, a videotaped standardized examination of eye movements was performed. Additional examinations were performed immediately before and 2 to 3 days after treatment with IVIg in 5 children. RESULTS: Seventeen children, ages 1.75 to 12.62 years, were examined. All had a stage I or II neuroblastoma resected 3 months to 11 years previously. None received any other treatment for the tumor. All but 1 had received at least 1 year of either oral corticosteroids or corticotropin (ACTH); 12 had received 1 or more courses of IVIg, 2 g/kg. Three had received other immunosuppressive treatment, including cyclophosphamide. Cognitive development and adaptive behavior were delayed or abnormal in nearly all children. Expressive language was more impaired than receptive language. Speech was impaired, including both intelligibility and overall output. Fine and gross motor abilities were impaired. Increased age was strikingly associated with lower scores in all areas. Behavioral problems early in the course included severe irritability and inconsolability in all; later, oppositional behavior and sleep disorders were reported. Opsoclonus abated in all, but abnormalities in pursuit eye movements were found in all 6 children cooperative with standardized examination. Outcome did not differ in children who were treated with ACTH versus oral steroids. Three children who had received cyclophosphamide fared poorly. Immediate versus delayed treatment was not associated with better outcome. IVIg improved both gross and fine motor and speech function acutely, but we could not confirm long-term benefit of IVIg. Total number of courses of IVIg was not associated with outcome. CONCLUSIONS: Opsoclonus-ataxia caused by neuroblastoma causes substantial developmental sequelae that are not adequately prevented by current treatment. The increased deficits in older children raise concern that this represents a progressive encephalopathy rather than a time-limited single insult. Although the study is cross-sectional and neither randomized nor blinded, we were unable to confirm a purported advantage of either ACTH over corticosteroids or of cyclophosphamide. A randomized study is needed but is difficult for this rare condition.

[Effects of pulmonary rehabilitation in patients with pulmonary tuberculosis sequelae].

Pulmonary rehabilitation was evaluated for a mean period of 3.9 weeks in 37 inpatients with pulmonary tuberculosis sequelae. The rehabilitation program consisted of relaxation, breathing retraining, exercise training, respiratory muscle training and instruction. Significant improvement was shown in VC (n = 37) on average from 1.48 l to 1.59 l, in FEV1.0 (n = 37) from 0.93 l to 1.02 l, in PaO2 (n = 35) from 67.1 Torr to 72.4 Torr, in 6-minute walking distance (n = 29) from 303 m to 339 m, in Pimax (n = 17) from 38.5 cmH2O to 47.5 cmH2O, in activity (n = 23) from 19.6 points to 22.5 points, in dyspnea (n = 22) from 18.4 points to 22.5 points and in QOL (n = 25) from 39.0 points to 44.2 points. The effects of pulmonary rehabilitation did not depend on past thoracic surgery for tuberculosis, pattern of ventilatory impairment, findings of chest radiography, or degree of insufficiency. These data suggest that pulmonary rehabilitation is of benefit for improving pulmonary function, exercise tolerance, symptoms and QOL in patients with pulmonary tuberculosis sequelae.

Osteochondral sequelae of meningococcemia: radiographic aspects.

The authors retrospectively analyzed the files of 11 patients with osteochondral sequelae of meningococcemia, which were referred to this service between 1988 and 1996. The purpose of this study was to radiographically evaluate bone and physeal injuries observed in these patients, deformities caused by them and correlate these findings with the current literature. During radiographic evaluation of patients with sequelae of meningococcemia, two distinct parameters should be observed: bone injury and physeal plate injury patterns. The most frequent bone injury pattern was lytic lesion and the most common physeal plate injury pattern was peripheral asymmetric physis destruction. The most frequent deformities were lower limb length discrepancy, angular deformities and digital amputations. Based upon the findings of the present research, a descriptive radiographic classification was proposed.

Interleukin 1 receptor antagonist gene polymorphism is associated with severe renal involvement and renal sequelae in Henoch-Schönlein purpura.

OBJECTIVE: To assess the influence of interleukin 1 receptor antagonist gene polymorphism (IL1RN) in the incidence of Henoch-Schönlein purpura (HSP) and cutaneous leukocytoclastic angiitis (CLA) and to determine if implications exist with severe systemic complications of HSP, in particular with severe renal involvement and permanent renal dysfunction (renal sequelae). METHODS: Patients from Northwest Spain with primary cutaneous vasculitis classified as HSP or hypersensitivity vasculitis (HV) according to proposed criteria were studied. Patients with HV were included if they had a biopsy proven small size blood vessel leukocytoclastic vasculitis limited to skin and also fulfilled the Chapel Hill Consensus Conference on the Nomenclature of Systemic Vasculitis definitions for CLA. All patients were required to have had at least 2 years' followup. Patients and ethnically matched controls were genotyped for IL-1 receptor antagonist intron 2 VNTR polymorphism. RESULTS: We examined 96 Caucasian patients (58 HSP and 38 CLA) and 109 controls. No allele or genotype differences between the whole group of HSP or CLA patients and controls were observed. We found a significant association between carriage of IL-1 receptor antagonist allele 2 (ILRN*2) and severe renal involvement, manifested as nephrotic syndrome and/or renal insufficiency (p = 0.016), and permanent renal involvement (renal sequelae) (p = 0.012). CONCLUSION: In unselected patients with cutaneous vasculitis, carriage of ILRN*2 alleles influences disease severity rather than susceptibility.
