RESUMO
PURPOSE: To report 3 cases of cherubism, one of whom underwent surgery for orbital manifestations, and to provide a literature review. CASE REPORTS: Our patients were normal at birth and developed painless enlarging of the cheeks and jaws when they were 4-5 years old. Ophthalmologic examinations showed mild proptosis, superior globe displacement and inferior scleral show in all cases. Cases 2 and 3 had lower lid skin discoloration. Computed tomography (CT) scans demonstrated bilateral multicystic lesions in the maxilla and mandible with cortical thinning in all cases. In Case 3, left eye hyperglobus and anisometropic amblyopia was seen. In this case, the CT scan showed a round, well-defined and homogeneous mass, involving the anterior and superior walls of the maxillary sinus on the left side, extending into inferior orbit. Debulking of the mass was performed at the surgery. The pathologic findings were compatible with the diagnosis of giant cell reparative granuloma. He returned 1 year after surgery with recurrence of the mass. DISCUSSION: A few cases were reported in the literature with histopathologically proven orbital cherubism. To our knowledge, lower lid skin discoloration in Cases 2 and 3 and anisometropic amblyopia in case 3 were not described elsewhere in cherubism cases. We recommend that all cases with cherubism must be examined by an ophthalmologist to diagnose and treat possible orbital manifestations.

BACKGROUND: To evaluate the prevalence of amblyopia risk factors in children that underwent probing for persistent congenital nasolacrimal duct obstruction (CNLDO). METHODS: The medical records of children with CNLDO (after 1 year of age) that underwent probing were reviewed. Amblyopia risk factors, based on the American Association for Pediatric Ophthalmology and Strabismus referral criteria in 2013, were sought in the patientsʹ records before probing. The proportion of the patients with anisometropia >1.5 diopters (D) was separately calculated. In unilateral cases of CNLDO, sphere, astigmatism, and spherical equivalent of the eyes with CNLDO were compared with contralateral eyes in order to assess the effect of CNLDO on refractive error. In the follow-up examinations, the success of the probing or the need for additional procedures (Crawford intubation, Monoka intubation, or dacryocystorhinostomy) was evaluated. The prevalence of anisometropia between 'successful probing' and 'failed probing' groups was compared. RESULTS: A total of 433 cases were included in the study. 41 cases (9.46 %) had amblyopia risk factors. Twenty-four cases (5.5 %) had anisometropia >1.5 D (spherical or cylindrical). In unilateral cases of CNLDO, the sphere and spherical equivalent of the eyes with CNLDO were significantly greater than those of the contralateral eyes (p < 0.001 for both). Thirty-nine patients (9 %) required other interventions due to failure of probing (failed probing group). There were significantly more anisometropia prevalence in this group, compared with the successful probing group, at the initial examination (p = 0.03). CONCLUSIONS: The findings of greater prevalence of anisometropia >1.5 D (compared with the prevalence in the general population) and significantly greater sphere and spherical equivalents in the eye with CNLDO (compared with contralateral eye) in unilateral cases with CNLDO, suggested some relationships between anisometropia and long-term untreated CNLDO. The finding of more anisometropia in failed probing cases may support the theory of structural abnormality as an explanation for the possible relationship between congenital nasolacrimal duct obstruction and anisometropia.

BACKGROUND: Nailfold capillaroscopy has been used as a non-invasive diagnostic method for microvasculature evaluation in various rheumatological disorders. The present study aimed to determine the utility of nailfold capillaroscopy in the diagnosis of Kawasaki Disease (KD). METHOD: In this case-control study nailfold capillaroscopy was performed in 31 patients with KD and 30 healthy controls. All nailfold images were evaluated for capillary distribution and capillary morphology such as enlargement, tortuosity, and dilatation of the capillaries. RESULT: Abnormal capillaroscopic diameter was identified in 21 patients from the KD group and 4 patients in the control group. The most common abnormality in capillary diameter was irregular dilatation in 11 (35.4%) KD patients and in 4 people (13.3%) in the control group. Distortions of the normal capillary architecture was commonly seen in the KD group (n=8). A positive correlation was observed between coronary involvement and abnormal capillaroscopic results (r=.65, P<.03). The sensitivity and specificity of capillaroscopy for the diagnosis of KD were 84.0% (95%CI: 63.9-95.5%) and 72.2% (95%CI: 54.8-85.8%), respectively. The PPV and NPV of capillaroscopy for KD were 67.7% (95%CI: 48.6-83.3) and 86.7% (95% CI: 69.3-96.2), respectively. CONCLUSION: Capillary alterations are more common in KD patients compared to control group. Thus, nailfold capillaroscopy can be useful in detecting these alterations. Capillaroscopy is a sensitive test for detecting capillary alternations in KD patients. It could be used as a feasible diagnostic modality for evaluating microvascular damage in KD.

BACKGROUND: Deficiency of adenosine deaminase 2 (DADA2) is an autosomal recessive autoinflammatory disease caused by mutations in the ADA2 gene. DADA2 has a broad spectrum of clinical presentations. Apart from systemic manifestations, we can categorize most of the signs and symptoms of DADA2 into the three groups of vasculitis, hematologic abnormalities, and immunologic dysregulations. The most dominant vasculitis features are skin manifestations, mostly in the form of livedo racemosa/reticularis, and early onset ischemic or hemorrhagic strokes. Hypogammaglobulinemia that is found in many cases of DADA2 brings immunodeficiencies into the differential diagnosis. Cytopenia, pure red cell aplasia (PRCA), and bone marrow failure (BMF) are the hematologic abnormalities commonly found in DADA. CASE PRESENTATION: We introduce eleven patients with DADA2 diagnosis, including two brothers and sisters, one set of twin sisters, and one father and his daughter and son. Ten patients (91%) had consanguineous parents. All the patients manifested livedo racemose/reticularis. Ten patients (91%) reported febrile episodes, and seven (64%) had experienced strokes. Only one patient had hypertension. Two of the patients (11%) presented decreased immunoglobulin levels. One of the patients presented with PRCA. Except for the PRCA patient with G321E mutation, all of our patients delivered G47R mutation, the most common mutation in DADA2 patients. Except for one patient who unfortunately passed away before the diagnosis was made and proper treatment was initiated, the other patients' symptoms are currently controlled; two of the patients presented with mild symptoms and are now being treated with colchicine, and the eight others responded well to anti-TNFs. The PRCA patient still suffers from hematologic abnormalities and is a candidate for a bone marrow transplant. CONCLUSIONS: Considering the manifestations and the differential diagnoses, DADA2 is not merely a rheumatologic disease, and introducing this disease to hematologists, neurologists, and immunologists is mandatory to initiate prompt and proper treatment. The efficacy of anti-TNFs in resolving the symptoms of DADA2 patients have been proven, but not for those with hematologic manifestations. Similarly, they were effective in controlling the symptoms of our cohort of patients, except for the one patient with cytopenia.

BACKGROUND: Kawasaki disease (KD) is often complicated by coronary artery lesion (CAL), including dilatation or aneurysms. Intravenous immunoglobulin (IVIG) is used with aspirin to prevent CAL in KD. OBJECTIVE: Given that the primary treatment for other vasculitis is the use of corticosteroids, this study has been performed to evaluate the effect of intravenous methylprednisolone pulse (IVMP) therapy in preventing CAL in KD. METHOD: A randomized, single-blind clinical trial was conducted on 40 KD patients aged six months to five years. Patients were randomized into two groups according to the main treatment plan in addition to aspirin: case group (IVMP for three consecutive days and then oral prednisolone for three days) and control group (intravenous immunoglobulin 2 g/kg). Echocardiography was performed for all children at least three times, during the acute phase, two weeks, and two months later. RESULTS: Data analysis at the end of the study was done on 40 patients (20 patients in each group). There were no significant differences in age and sex distribution, mean fever, and acute phase duration, as well as baseline echocardiography in the two groups. The frequency of CAL was 20% in the case group and 45% in the control group, after two weeks (p<0.05), but there was no significant difference between two groups in types of coronary artery lesion after two weeks and the frequency and severity of CAL after two months. CONCLUSION: IVMP as initial line therapy effectively control systemic and vascular inflammation and decrease coronary artery damage in KD.
RESUMO
BACKGROUND: Hyper-inflammatory syndrome in children and young adult occur 2-6 weeks after COVID-19 infection or closed contact with COVID-19 persons. In this study, the laboratory data and echocardiography and abdominal ultrasonography assessments were evaluated before and after Methylprednisolone pulse as an initial treatment of hyper-inflammatory syndrome. Therefore, the aim of this study is to assessment the clinical manifestations and laboratory data and outcome after methylprednisolone pulse as an initial treatment. METHOD: In this retrospective study, the demographic status, clinical features, laboratory data, echocardiography, abdominal ultrasound, treatment and outcome of 31 pediatric patients under 16 years old, with inflammatory process after COVID-19 were evaluated. The clinical assessments, laboratory data, sonography and echocardiography were evaluated before and after methylprednisolone pulse. The patients were divided in two age group < and ≥ 7 years old and the clinical manifestations were compared with each other. The Mann-Whitney U test was used to assess the difference in quantitative variables between two groups. To compare pre- and post- treatment values, Wilcoxol test was used. To assess the correlation between qualitative variables chi-square test was used. The level of significant was considered 0.05. These patients with fever and hyper-inflammation features admitted to the referral pediatric rheumatology ward in Children Medical Center of Tehran University of medical sciences, from April 2020 to May 2021 were assessed. RESULT: The mean age ± SD were (5.94 ± 3) and 51.6% (16) patients were male and 48.4% (15) patients were female. The most documented of previous COVID infection were antibody positive in about 27 (87%) patients. Moreover, 1 (3.8%) was PCR positive, 2 (7.7%) were positive in both PCR and serology and 3(11.5%) had closed contact with COVID-19 patients. About 9(29%) of patients were admitted in Intensive Care Unit (ICU). There were significant correlation between days of delay in starting treatment and ICU admission (P-value = 0.02). The mortality rate was negative in patients and no re-hospitalization was documented. There were significant differences (P-value < 0.05) between lymphocytes, platelet, Erythrocyte Sedimentation rate, C-reactive protein, Aspartate transaminase, Alanine transaminase and ferritin before and after treatment. Skin rashes and cardiac involvement totally as carditis (myocarditis, vulvulitis and pericarditis) (33.3%) and coronary involvements (53.3%) were the most prominent initial presentation in patients. There were near significant correlation (P-value = 0.066) between ferritin level and carditis before treatment. Cervical lymphadenopathy was seen significantly more in ≥ 7 years old (P-value = 0.01). CONCLUSION: Multisystem inflammatory system in children as a hyperinflammatory syndrome could be treated with first step methylprednisolone pulse with decreasing inflammation in laboratory data and cardiac involvements and good outcome. Furthermore, the ferritin level may be one of the predictor of severe hyper-inflammatory syndrome leading to aggressive and urgent treatment with methylprednisolone pulse.
RESUMO
BACKGROUND: This study aimed to assess the relationship of air pollution and plasma surrogate markers of endothelial dysfunction in the pediatric age group. METHODS: This cross-sectional study was conducted in 2009-2010 among 125 participants aged 10-18 years. They were randomly selected from different areas of Isfahan city, the second large and air-polluted city in Iran. The association of air pollutants' levels with serum thrombomodulin (TM) and tissue factor (TF) was determined after adjustment for age, gender, anthropometric measures, dietary and physical activity habits. RESULTS: Data of 118 participants was complete and was analyzed. The mean age was 12.79 (2.35) years. The mean pollution standards index (PSI) value was at moderate level, the mean particular matter measuring up to 10 µm (PM10) was more than twice the normal level. Multiple linear regression analysis showed that TF had significant relationship with all air pollutants except than carbon monoxide, and TM had significant inverse relationship with ozone. The odds ratio of elevated TF was significantly higher in the upper vs. the lowest quartiles of PM10, ozone and PSI. The corresponding figures were in opposite direction for TM. CONCLUSIONS: The relationship of air pollutants with endothelial dysfunction and pro-coagulant state can be an important factor in the development of atherosclerosis from early life. This finding should be confirmed in future longitudinal studies. Concerns about the harmful effects of air pollution on children's health should be considered a top priority for public health policy; it should be underscored in primordial and primary prevention of chronic diseases.

BACKGROUND: Nailfold capillaroscopy is a noninvasive technique to recognize peripheral microangiopathy, which is an important feature in systemic lupus erythematosus (SLE). The aims of the present study were to investigate the prevalence of nailfold capillaroscopy (NFC) changes in juvenile systemic lupus erythematosus (JSLE), find out patterns of these changes, and correlate findings with clinical and laboratory parameters. METHODS: Forty-nine patients with SLE, all meeting the 1997 revised ACR criteria for SLE classification, and 30 healthy controls were included. A digital video camera was used to capture nailfold capillary images. Computerized image processing was used for analysis. RESULTS: Different abnormal NFC changes were observed with abnormal morphology, the increased diameter and abnormal loop densities in 55.1%, 93.9%, and 26.5% of the patients, respectively. No statistically significant differences were depicted between capillaroscopy with age, gender, autoantibodies (APLs, anti-ds DNA), antiphospholipid antibody syndrome, thrombotic angiopathy, renal function tests (Bun, Cr), and abnormal urine analysis. However, a significant correlation was found between the branched pattern and the CNS involvement group (P value <0.03). CONCLUSIONS: Different abnormal NFC changes are quite common among patients with SLE, and nailfold capillaroscopy is an effective method to monitor such changes. Treatment strategies may change in the branched pattern of nailfold capillaroscopy due to CNS involvement.
RESUMO
BACKGROUND: Alteration in serum expression of Transforming Growth Factor-beta (TGF-ß) and IL-10 have been suggested to play a role in the pathogenesis of Kawasaki Disease (KD). Inconsistent reports exist on the association of IL-10 polymorphisms with KD susceptibility and Coronary Artery Aneurysms (CAA). METHODS: A number of 110 paediatric patients with KD and 140 healthy individuals were recruited to investigate the frequency of Single Nucleotide Polymorphisms (SNPs) of TGF-ß C/T at codon 10 (rs1982073), C/G at codon 25 (rs1800471) and IL-10 A/G at -1082 (rs1800896), C/T at -819 (rs1800871) and A/C at -592 (rs1800872) and their respective genotype and haplotypes. A comprehensive search was performed in MEDLINE and SCOPUS using the keywords of interleukin 10, transforming growth factor beta, and Kawasaki disease. Moreover, previous studies investigating the TGF-ß and IL-10 polymorphisms in KD were evaluated. Review Manager Version 5.1 Software was used to perform meta-analysis. RESULTS: There was no significant association between allelic or genotypic variants in the mentioned polymorphisms in TGF-ß or IL-10 with KD or CAA. The only significant haplotypic variant was TC variant at codon 10, and 25 of TGF-ß polymorphisms were associated with higher risk of KD. Meta-analysis of a total number of 770 patients vs. 1471 healthy controls showed no difference in the frequency of any of the IL-10 genetic variants in KD patients, regardless of the presence of CAA. CONCLUSION: Polymorphisms of TGF-ß or IL-10 are not associated with additional risk for KD in Iranian population. IL-10 polymorphisms at -1082, -819 and -592 positions are not associated with KD, nor do they predict coronary artery aneurysm formation.
RESUMO
OBJECTIVES: Familial Mediterranean Fever (FMF) is one of the most prevalent periodic fever syndromes; MEFV, the responsible gene for the disease, is in the short arm of chromosome16. In the considerable count of the FMF patients, only one mutation is found in the MEFV and parents, who were the obligatory carriers for that mutation, were asymptomatic. The aim of this study was to evaluate these asymptomatic parents in regard to mutation in MEFV gene and similarity between parents and offspring patients. METHODS: In this cross-sectional study, asymptomatic parents of FMF patients enrolled the study were referred to periodic fever clinic or pediatric rheumatology clinic of Tehran University of Medical Sciences. The patients should have at least one mutation in MEFV gene and none of them had any family history of autoinflammatory disease. Twelve mutations in MEFV gene were assessed in the parents by Vienna Lab FMF Strip Assay kit by MAS PCR/Reverse hybridization. RESULTS: Forty-three patients and their parents participated in the study. Sixty-three percent (27) of patients were male. Onset of disease symptoms in 31 patients (72%) was before 4 years of old. Nine (21%) of the patients had homozygote, 16 (37%) compound heterozygote, and 17(40%) heterozygote for MEFV mutation; there was a case of complex alleles mutations (2%). M694V/M694V in 4 patients (9%) was the most homozygote genotype, and M694V/R761H in 4 (9%) and E148Q in 7 (16%) were the most compound heterozygote and heterozygote genotype, respectively. M694V, M680I, and E148Q were the most mutation in the parents. Overall, 41 patients had mutations similar to their parents' mutation, except 2 whose parents had no mutation, but a patient did. CONCLUSION: It seems that occurrence of new mutations in offspring is not prevalent among FMF patients and there are other reasons for different clinical presentation in similar mutation carriers. On the other hand, in ethnicities with high prevalence of FMF, new mutation in descendant may occur, infrequently.
RESUMO
AIM: Kawasaki disease (KD) is a systemic vasculitis of medium-sized arteries. High levels of interleukin 4 (IL-4) and the dominance of Th2 cytokines seem to be a key feature in the acute phase of KD. In this study, the role of IL-4 and IL-4R gene polymorphisms were investigated in Iranian children with KD. METHODS: Fifty-five patients with KD and 140 healthy subjects as a control group were enrolled in this study. Single nucleotide polymorphisms (SNPs) of IL-4 gene at positions -1098 (rs2243248), -590 (rs2243250) and -33 (rs2070874), as well as IL-4RA gene at position +1902 (rs180275) were assessed in patients and the control group. RESULTS: The C allele and CC genotype of IL-4 gene at position -590 and at position -33 had positive associations and the CT genotype at -590 was negatively associated with KD (odds ratio (95% CI) = 0.04 [0.01-0.09]). The haplotype TCC was more frequent among the patients, while the haplotypes TTT and TTC had a negative association with KD. CONCLUSION: IL-4 polymorphisms might be associated with KD in an Iranian population.

AIM: Kawasaki disease (KD) is a systemic vasculitis of children associated with cardiovascular sequelae. Proinflammatory cytokines play a major role in KD pathogenesis. However, their role is both influenced and modified by regulatory T-cells. IL-1 gene cluster, IL-6 and TNF-α polymorphisms have shown significant associations with some vasculitides. Herein we investigated their role in KD. METHODS: Fifty-five patients with KD who were randomly selected from referrals to the main pediatric hospital were enrolled in this case-control study. Single nucleotide polymorphisms (SNPs) of the following genes were assessed in patients and 140 healthy subjects as control group: IL-1α at -889 (rs1800587), IL-1ß at -511 (rs16944), IL-1ß at +3962 (rs1143634), IL-1R at Pst-I 1970 (rs2234650), IL-1RN/A at Mspa-I 11100 (rs315952), TNF-α at -308 (rs1800629), TNF-α at -238, IL-6 at -174 (rs1800795) and IL-6 at +565. RESULTS: Twenty-one percent of the control group had A allele at TNF-α -238 while only 8% of KD patients had A allele at this position (P = 0.003, OR [95%CI] = 0.32 [0.14-0.71]). Consistently, TNF-α genotype GG at -238 had significant association with KD (OR [95% CI] = 4.31 [1.79-10.73]). Most controls carried the CG genotype at IL-6 -174 (n = 93 [66.9%]) while GG genotype was the most common genotype (n = 27 [49%]) among patients. Carriers of the GG haplotype at TNF-α (-308, -238) were significantly more prevalent among the KD group. No association was found between IL-1 gene cluster, allelic or haplotypic variants and KD. CONCLUSION: TNF-α GG genotype at -238 and GG haplotype at positions -308 and -238 were associated with KD in an Iranian population.

PURPOSE: To describe an infant with PHACE(S) syndrome [posterior fossa anomalies (P), hemangiomas (H), arterial anomalies (A), cardiac abnormalities and coarctation of aorta (C), eye abnormalities (E), and the sternal defects (S)] with unusual strabismus, congenital glaucoma, and new systemic manifestations. METHODS: A 6-month-old girl was referred with large hemangiomas on the left side of the face. RESULTS: In the ocular examination, right esotropia and hypotropia, and limitation of elevation in adduction in the right eye were seen. Morning glory disk anomaly was seen in the left fundus. Intraocular pressure (IOP) was 28 mmHg in the right eye and 15 mmHg in the left eye. Brain computed tomography (CT) scan demonstrated Dandy-Walker malformation. In the CT angiography of the thoracic arteries, coarctation of aorta in descending part, the aberrant origin of the left subclavian artery from the end of the aortic arch, and anomalous origin of the left vertebral artery from the posterior aspect of the aortic arch were found. Therefore, the presence of large facial hemangioma, posterior fossa anomaly, aortic arch anomalies, and morning glory disk confirmed the diagnosis of PHACE(S) syndrome. Propranolol (0.5 mg/kg/day) was initiated to treat hemangioma and coarctation of aorta. Due to uncontrolled glaucoma, goniotomy was performed in the right eye 3 months after the first visit. One year after the initial visit, the hypotropia and esotropia of the right eye considerably decreased. CONCLUSIONS: To our knowledge, this report was the first report of a pattern like Brown's syndrome (may be called apparent Brown's syndrome) and the second report of the congenital glaucoma in a case of PHACE(S) syndrome. In addition, the anomalous origin of the vertebral artery from the aortic arch has not been reported in the PHACE(S) syndrome. Thus, the clinicians should perform the glaucoma work-up for each patient with this syndrome.
RESUMO
INTRODUCTION: Headache is a common neuropsychiatric manifestation of juvenile systemic lupus erythematous (JSLE). Pseudotumor cerebri (PTC) is an uncommon cause of headache, presenting especially in active JSLE. In this paper, we report a case of missed intractable headache that was eventually diagnosed as PTC and presented as the first manifestation of JSLE. CASE PRESENTATION: A 9-year-old girl with a history of progressive headache for four months, fever, fatigue, myalgia, arthralgia, small-joint arthritis of the hands, and recent diplopia was referred to our clinic. The diagnosis of PTC in the background of JSLE was made based on her history, physical examination, positive laboratory findings, and increased intracranial pressure, with normal neuroimaging. Treatment with high-dose prednisolone led to dramatic resolution of the headache. CONCLUSIONS: It seems that a complete neurologic examination in newly diagnosed SLE patients is mandatory, especially in the presence of any neuropsychiatric manifestations, such as headache.
RESUMO
PURPOSE: To compare the laboratory data and changes in these data between patients with MAS and patients with flare-up of the autoimmune diseases. METHODS: In a prospective study, the static laboratory data and dynamic changes in the selected data in 17 consecutive patients with MAS and 53 patients with active disease of SJIA, PJIA, Kawasaki disease, and SLE were compared. The ROC curve analysis was used to evaluate cut-off points, sensitivity, and specificity of the static and dynamic laboratory data to differentiate between MAS and active disease. RESULTS: In the MAS group, the mean CRP3, ALT, AST, total bilirubin, ferritin, LDH, PT, PTT, and INR were significantly higher and the mean WBC2, PMN2, Lymph2, Hgb1, 2, 3, ESR2, serum albumin, and sodium were significantly lower than in control group. Some of the important cut-off points were PLT2 < 209000/microliter, AST > 38.5, ALT > 38, WBC < 8200 × 103/UL, ferritin > 5277 ng/mL. CONCLUSION: The dynamic changes in some laboratory data, especially PLT, can differentiate between MAS and active disease. The changes in WBC, PMN, and ESR and the levels of the liver enzymes may also be helpful in the early differentiation. Very high levels of ferritin may also help the diagnosis along with other clinical and laboratory signs.

BACKGROUND: Chronic recurrent multifocal osteomyelitis (CREMO) is one of the autoinflammatory bone disorders due to disturbance in innate immune system. Up to now, there is no reported case of caseous granulomas in the CREMO. We report a boy with sterile granolumatous osteomyelitis. CASE PRESENTATION: A four-year-old boy presented with swelling and pain in the left wrist, malaise and bilateral erythematous pustulosis on the palmar region which had resolved spontaneously after about 7 days. The histopathology of the lesions showed severe acute and chronic inflammatory process and chronic granulomatous reaction with caseating necrosis (granulomatous osteomyelitis). The direct smear, culture and PCR for the mycobacterium tuberculosis and atypical mycobacteria were negative. About five months after initiation of the anti-mycobacterial treatment, he was referred to the rheumatology clinic with left elbow pain, effusion and decreased range of motion, and bilateral erythematous palmar pustulosis. He was diagnosed as CREMO based on two exacerbations, repeatedly negative cultures, and concomitant acute and chronic lesions in the histopathology and X-ray. Naproxen and pamidronate every 3 months were started and all other medications were stopped. Two months after the first dose of pamidronate, he became symptom-free and forearm X-ray showed disappearance of the osteolytic lesions and periosteal reactions. CONCLUSION: The diagnosis of CREMO should be considered in the patients with lytic bone lesions. In addition, the clinicians should be aware of the possibility of caseating granuloma in the cases with possible diagnosis of CREMO.
RESUMO
BACKGROUND: Neonatal lupus erythematosus (NLE) is a transient autoimmune disease of developing fetus and neonate in mothers with systemic lupus erythematosus (SLE). In this report we introduce an infant with NLE whose mother had rheumatoid arthritis. CASE PRESENTATION: Our case was a 40 day old male infant with discoid-like and annular skin lesions over forehead and neck, irritability and low grade fever. There was a history of prematurity due to preeclampsia. There was no cytopenia or cardiac involvement but liver enzymes were more than 5-fold increased. FANA, Anti Ro and La were negative. The mother had a history of un-controlled rheumatoid arthritis for 12 years with deformity in metacarpal and PIP and ulnar deviation in hands. FANA=1/640 and anti-SSB/La was positive in the mother but there was no other clinical and paraclinical sign of SLE. Without any treatment and during months, the skin and mucosal lesions gradually disappeared without any scar and liver enzymes reached the normal level. After 6 months follow up, he was symptom free with normal growth and development. CONCLUSION: We recommend to check anti SSA/Ro and anti SSB/La antibodies in all pregnant women with connective tissue diseases to prevent life-threatening involvement of the infant.
RESUMO
A 7-year-old boy with high grade fever (39°C) and warm, erythematous, and indurated plaque above the left knee was referred. According to the previous records of this patient, these indurated plaques had been changed toward abscesses formation and then spontaneous drainage had occurred after about 6 to 7 days, and finally these lesions healed with scars. In multiple previous admissions, high grade fever, leukocytosis, and a noticeable increase in erythrocyte sedimentation rate and C-reactive protein were noted. After that, until 7th year of age, he had shoulder, gluteal, splenic, kidney, and left thigh lesions and pneumonia. The methylprednisolone pulse (30 mg/kg) was initiated with the diagnosis of Sweet's syndrome. After about 10-14 days, almost all of the laboratory data regressed to nearly normal limits. After about 5 months, he was admitted again with tachypnea and high grade fever and leukocytosis. After infusion of one methylprednisolone pulse, the fever and tachypnea resolved rapidly in about 24 hours. In this admission, colchicine (1 mg/kg) was added to the oral prednisolone after discharge. In the periodic fever and neutrophilic dermatosis, the rheumatologist should search for sterile abscesses in other organs.
