Arterial stroke in a child with Seckel syndrome with a pattern of non-moyamoya vasculopathy.

Seckel syndrome is a rare autosomal recessive disorder, characterized by growth retardation and multiple anomalies associated with CNS vasculopathy. We describe a child with Seckel syndrome who developed a stroke due to non-moyamoya vasculopathy.

Moyamoya Disease in a Child With Fanconi Anemia: An Anomaly or a Complication.

Fanconi anemia (FA) is an inherited bone marrow failure syndrome associated with congenital anomalies and a predisposition to cancer. We report the case of a 9-year-old boy with FA who developed an abrupt onset of hemiplegia and dysarthria. The diagnosis of moyamoya disease (MMD) was suggested by magnetic resonance angiography (MRA) which demonstrated severe stenosis in the right internal carotid artery along with collateral vessel formation in the right basal ganglia. It is questioned whether the moyamoya pattern in this case is part of congenital malformations associated with FA or is the result of recurrent bleedings around the carotid siphon.

An unusual imaging presentation of pediatric bacterial meningoencephalitis: a case-report study.

Background: Bacterial meningoencephalitis is a serious infection affecting the brain and its surrounding membranes. While imaging studies play a crucial role in diagnosing this condition, the typical radiological findings are well-documented. However, this case report describes an unusual imaging presentation that deviates from the expected patterns, emphasizing the need for awareness of such variations. Case presentation: A 7-year-old female with no prior medical history was referred to our hospital with fever, seizure, and loss of Consciousness. She had mild flu a week before admission. The duration of seizure episodes were 2-3 min, with tonic-clonic uncontrollable jerky movements. Brudzinski and Kernig signs were positive and plantar reflex was upward bilaterally in the physical examination. The computed tomography (CT) scan showed brain ventriculomegaly/hydrocephalus, and MRI findings indicated multiple foci located at cerebellum, basal ganglia, and thalamus alongside intensely restricted diffusion of the layering debris, suggesting pyogenic ventriculitis. Cerebrospinal fluid (CSF) analysis showed severe hypoglycorrhachia, despite non-significant increase of protein. The patient was undergone antibiotic therapy with ceftriaxone, vancomycin and rifampin, resulting in normalization of CSF values. Conclusion: This case report highlights the importance of recognizing and interpreting unusual imaging presentations of bacterial meningoencephalitis in paediatric patients. It emphasizes the need for a comprehensive diagnostic approach, including clinical evaluation, laboratory tests, and imaging studies, to ensure accurate diagnosis and appropriate management of this potentially life-threatening condition. Further research and awareness of atypical imaging findings are warranted to enhance our understanding and improve patient outcomes.

Local injection of infliximab into calcinosis lesions in patients with juvenile dermatomyositis (JDM): a clinical trial.

BACKGROUND: Juvenile Dermatomyositis (JDM) is a rare autoimmune disorder that primarily affects muscles and skin. One of the severe complications associated with JDM is calcinosis, and treating this condition presents significant challenges. This study aimed to evaluate the efficacy and safety of local injection of infliximab into calcinosis lesions in patients with JDM. METHODS: In this clinical trial, five patients diagnosed with JDM and calcinosis lesions were enrolled. The primary treatment consisted of weekly infliximab injections for 16 weeks, targeting all four sides of each lesion. Lesion dimensions, including length and width, were documented and monitored weekly. Before the intervention, patients underwent radiographic imaging. After the final injection in week 16, a follow-up radiographic assessment was performed. Data were analyzed using the Generalized Estimating Equation (GEE) method. RESULTS: The lesions' size significantly decreased in both length and width during each visit. On average, the lesion length reduced by 2.66%, and the width shrank by 3.32% per visit. Based on radiographic findings, the average length and width of lesions at the initial visit were 12.09 ± 5.05 mm (range: 6.00-25.50 mm) and 6.35 ± 3.00 mm (range: 2.00-16.00 mm), respectively. The average length and width at the last visit were 5.59 ± 7.05 mm (range: 0-23.00 mm) and 3.41 ± 4.05 mm (range: 0-13.00 mm), respectively. No specific side effects related to the treatment were reported. CONCLUSIONS: The results suggest that the direct administration of infliximab into the calcinosis lesions of patients with JDM could be a safe and effective treatment approach. TRIAL REGISTRATION: Name of the registry: The effect of infliximab injection into calcinosis lesions on patients with juvenile dermatomyositis (JDM), Trial registration number: IRCT20210808052107N1, Registration date: 2022-07-22, URL of trial registry record: https://en.irct.ir/trial/58329 .

Extraskeletal conventional chondrosarcoma of genitalia in a child- An unusual pathology for a rare tumor.

INTRODUCTION AND IMPORTANCE: Chondrosarcoma is a rare malignant tumor considered as the second common sarcoma of bone following osteosarcoma. Less than 5 % of chondrosarcomas occur in children. Conventional chondrosarcoma is the most common type observed as skeletal tumors. Extraskeletal chondrosarcomas account for about 1 % of chondrosarcomas. They are almost always of myxoid or mesenchymal subtypes. CASE PRESENTATION: A 4-year-old girl was referred with pain and palpable mass in the labia majora since 2 years of age for which she had undergone twice biopsies, reported as soft tissue enchondroma. At this time, complete excision of the lesion with negative margins was carried out. The pathology was in favor of extraskeletal chondrosarcoma of conventional type without any evidence of bone involvement. CLINICAL DISCUSSION: Our case was a very young child with extraskeletal conventional chondrosarcoma, not reported yet in the literature. The vast majority of extraskeletal myxoid chondrosarcomas arise in the soft tissues of the extremities. The lesion in this case was located within the subcutaneous tissue of the labia majora; however, the tumor was not compatible with myxoid chondrosarcoma. Mesenchymal chondrosarcoma is another type of extraskeletal chondrosarcoma but the histopathologic patterns observed in our patient were not compatible even with the mesenchymal chondrosarcoma. CONCLUSION: We present a unique case of extraskeletal chondrosarcoma in a child with conventional subtype which has not been reported in the literature. In addition, the lesion was assumed to arise from a previous soft tissue enchondroma of the labia majora since infancy which makes the case distinctive.

Congenital Skin Rashes in an IVF Baby Progressed to Multisystem Langerhans Cell Histiocytosis with Lung and Bone Involvement: A Case Report and Literature Review.

Langerhans cell histiocytosis is an uncommon proliferative disorder that may influence many organs; so, the clinical presentations vary. Here we describe an 85-day-old female who was born with In vitro fertilization after 10 years of infertility. She referred to us due to severe pulmonary insufficiency and congenital progressive maculopapular rash with desquamation. There were significant cystic changes in chest imaging studies. Further evaluation demonstrated lytic lesions in cranial, femoral, and humorous bones. The skin biopsy verified the diagnosis of LCH. A combination of Vinblastine, VP16, and Dexamethasone regimen was applied for the patient. In the course of the disease, she encountered multiple bilateral pneumothoraxes but didn't respond to tube thoracostomy and chemotherapy management. The patient died due to respiratory failure raised from complications of lung involvement as a multisystem LCH, 29 days later. Pediatricians should pay much more attention to the cutaneous lesions in the neonatal period especially if there is any risk factor for presenting LCH such as IVF. The lesions should be monitored closely owing to a high correlation between skin lesions and MS LCH.

The Radiological Manifestations of Phagocytic Primary Immunodeficiencies in Children.

Primary immunodeficiencies are a diverse group of rare genetic disorders, among which phagocytic dysfunction impairs neutrophil function in a wide range of inherited disorders. Due to the heterogeneity of the disorders a multidisciplinary approach is often required for early diagnosis and initiation of appropriate treatments. The aim of this study was to evaluate the imaging findings in children admitted with phagocytic primary immunodeficiencies. Thirty-five children who fulfilled the inclusion criteria for phagocytic dysfunction were enrolled in this study. The patients were under close observation and monitoring from January 2011 until data locking in December 2017. The diagnosis of phagocytic immunodeficiency was confirmed by the patient's clinical course, presentation features, and laboratory data.  Among the 35 patients studied, the most frequent condition was chronic granulomatous disease (CGD) (23 patients), followed by different types of neutropenia (8 patients) and Job's syndrome (4 patients). Mediastinal and hilar lymphadenopathies and consolidation were the most frequent presentations. There was a significant relationship between mediastinal/hilar lymphadenopathies and fungal infections. A meaningful relationship was also found between pulmonary nodules without halo signs in patients with concomitant tuberculosis and fungal infections. A significant correlation was found between CGD, pulmonary fibrotic changes, and mediastinal lymphadenopathies. The most frequent radiological manifestations in children included mediastinal and hilar consolidations. Physicians' awareness of the radiological and clinical manifestations of these inherited diseases may be helpful in the early diagnosis and timely initiation of specific prophylaxis measures to prevent infections and also to initiate hematopoietic stem cell transplantation as the curative management modality.

Relapse of nephrotic syndrome with unusual thromboembolic event: A case report.

Key Clinical Message: Most children with nephrotic syndrome heal without any sequelae. However, rare life-threatening complications such as thromboembolism may occur in pediatric nephrotic syndrome and should be considered in those with a new-onset neurologic deficit. Abstract: The thromboembolism (TE) as a complication of nephrotic syndrome (NS) is rare and serious, and may involve renal, cerebral, pulmonary, or peripheral venous and/or arterial thrombosis. Here, we describe a 4.5-year-old male with a history of nephrotic syndrome, who developed hemorrhagic stroke in the territory of middle cerebral artery (MCA).

Arterial tortuosity syndrome presented as nonvisualization of thoracic aorta in preoperative transthoracic echocardiogram: A case report.

Arterial tortuosity syndrome is a rare genetic disorder characterized by dilation, elongation, and significant tortuosity of major arteries. Approximately 100 cases of this disorder have been reported worldwide, including 3 reports in Iran. We describe a case of arterial tortuosity syndrome suspected during the preoperative evaluation for hypertrophic pyloric stenosis, where the thoracic aorta was not visualized appropriately in transthoracic echocardiography. Our report focuses on identifying the disease through diagnostic imaging.

Acute Kidney Injury in Pediatric Patients with COVID-19; Clinical Features and Outcome.

INTRODUCTION: Renal disorders have been reported as the underlying cause as well as complications of critical COVID-19 in pediatric patients. The purpose of this study was to investigate the pattern of kidney involvement, particularly acute kidney injury (AKI), among pediatric patients with COVID-19. METHODS: In this prospective study, hospitalized pediatric patients with a clinical diagnosis of COVID-19 were enrolled. Demographic, clinical, and laboratory findings were collected and analyzed using a mixed method of qualitative and quantitative approaches and descriptive statistics. RESULTS: One hundred and eighty-seven patients, including 120 (64.2%) males and 67 (35.8%) females with COVID-19 with a median age (interquartile range) of 60 (24 to 114) months were enrolled in this study. Most patients (n = 108, 58.1%) had one or two underlying comorbidities, mainly malnutrition (77.4%), neurologic/learning disorders (21.4%), and malignancy (10.2%). According to the Kidney Disease Improving Global Outcomes (KDIGO) classification, AKI was detected in 38.5% of patients (stage 1: 55.6%, stage 2: 36.1%, and stage 3: 8.3%) at presentation or during hospitalization. Nine patients (4.8%) required hemodialysis and 16 (8.6%) eventually died. There was no significant association between AKI and admission to the pediatric intensive care unit (PICU) (P > .05), a multisystem inflammatory syndrome in children (MIS-C) (P > .05), comorbidities (P > .05), and mortality rate (P > .05). CONCLUSION: Kidneys are among the major organs affected by COVID-19. Although kidney abnormalities resolve in the majority of pediatric COVID-19 infections, particular attention should be paid to serum creatinine and electrolyte levels in patients affected by COVID-19, particularly children with a history of malnutrition and kidney disorders.  DOI: 10.52547/ijkd.7151.

Effects of omega-3 supplementation on endothelial function, vascular structure, and metabolic parameters in adolescents with type 1 diabetes mellitus: A randomized clinical trial.

Background: Vascular dysfunction is a major complication of diabetes mellitus that leads to cardiovascular disease (CVD). This study aimed to examine the effects of omega-3 consumption on endothelial function, vascular structure, and metabolic parameters in adolescents with type 1 diabetes mellitus (T1DM). Methods: In this randomized, double-blind, placebo-controlled clinical trial, 51 adolescents (10-18 years) with T1DM completed the study. Patients received 600 mg/day [containing 180 mg eicosapentaenoic acid (EPA) and 120 mg docosahexaenoic acid (DHA)] of omega-3 or placebo for 12 weeks. Flow-mediated dilation (FMD), carotid intima-media thickness (CIMT), high-sensitivity C-reactive protein (hs-CRP), erythrocyte sedimentation rate (ESR), triglycerides (TG), low-density lipoprotein (LDL), high-density lipoprotein (HDL), total cholesterol, blood urea nitrogen (BUN), creatinine, fasting blood sugar (FBS), hemoglobin A1C (HbA1c), homeostatic model assessment for insulin resistance (HOMA-IR), quantitative insulin sensitivity check index (QUICKI), serum insulin (SI), urine albumin-creatinine ratio (uACR), blood pressure, and anthropometric indices were assessed at the baseline and after the intervention. Results: Following supplementation, omega-3 significantly increased FMD (3.1 ± 4.2 vs. -0.6 ± 4%, p = 0.006) and decreased TG (-7.4 ± 10.7 vs. -0.1 ± 13.1 mg/dl, p = 0.022) in comparison with the placebo group. However, no significant difference was observed regarding CIMT (-0.005 ± 0.036 vs. 0.003 ± 0.021 mm, p = 0.33). Although hs-CRP was significantly decreased within the omega-3 group (p = 0.031); however, no significant change was observed compared to placebo group (p = 0.221). Omega-3 supplementation had no significant effect on other variables. Conclusion: Given the elevation in FMD and reduction in TG, omega-3 supplementation can improve vascular function and may reduce the risk of cardiovascular disease in adolescents with T1DM patients.

Exacerbation of Congenital Hydronephrosis as the First Presentation of COVID-19 Infection in Children.

Background: Congenital hydronephrosis is one of the most common abnormalities of the upper urinary tract, which can be exacerbated by a variety of intrinsic or extrinsic triggers. The urinary tract system is one of the major organs complicated by COVID-19 infection. Case Presentations. Here, we report five patients with an established diagnosis of congenital hydronephrosis, who presented with acute abdominal pain and fever and an abrupt increase in the anteroposterior pelvic diameter (APD). Patients had a previous stable course and were under regular follow-up with serial ultrasonographic studies. They underwent surgery or supportive treatment due to the later exacerbation of hydronephrosis. Based on the clinical and imaging findings, no plausible etiologies for these exacerbation episodes, including infection, nephrolithiasis, or abdominal masses, could be postulated. The common aspect in all these patients was the evidence of a COVID-19 infection. Conclusions: Infection with COVID-19 in children with antenatal hydronephrosis may exacerbate the degree of hydronephrosis and renal APD in ultrasonography, which itself may be mediated by the increase in inflammatory mediators.

A multicenter retrospective study of clinical features, laboratory characteristics, and outcomes of 166 hospitalized children with coronavirus disease 2019 (COVID-19): A preliminary report from Iranian Network for Research in Viral Diseases (INRVD).

BACKGROUND: The objectives of this study were to analyze the clinical features and laboratory profiles and risk factors associated with critical illness of children with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). METHODS: One hundred and sixty-six coronavirus disease 2019 (COVID-19) Iranian pediatric patients were recruited through a collaborative research network between March and May 2020. Demographics, clinical, laboratory, and radiological results were obtained from patient files. RESULTS: Of 166 patients, 102 (61%) and 64 (39%) were males and females, respectively. Ninety-six (57.8%) and 70 (42.2%), had moderate and severe conditions, respectively. Thirty (18%) of patients died. The common symptoms were fever (73%), cough (54%), and shortness of breath, headache decrease in neutrophil and platelet counts; increase values in lactate dehydrogenase, decrease in the blood pH and HCO3 were significantly associated with the disease severity. 54% and 56% of patients showed abnormal radiographic appearance in Chest X-ray and in chest computed tomography scan, respectively. Sixty-one (36.7%) of patients were referred to intensive care unit (ICU). The coexistence of comorbidity was the main factor associated with ICU admission, shock, arrhythmia, acute kidney injury, acute respiratory distress syndrome, acute cardiac injury, and death. CONCLUSIONS: We describe a higher than previously recognized rate of COVID-19 mortality in Iranian pediatric patients. Epidemiological factors, such as the relatively high case fatality rate in the country and the presence of underlying diseases were the main factors for the high death rate.

A case of diffuse leptomeningeal glioneuronal tumor in a 10-year-old boy: First report from Iran.

A 10-year-old boy who was referred due to acute hydrocephalus symptoms was diagnosed as the first case of pediatric DLGNT in Iran. The results suggested that using shunting for hydrocephaly and anti-seizure medicines, as well as chemotherapeutic agents, can be an effective treatment strategy for DLGNT. Although the patient was stable without a tumor recurrence for a limited follow-up period of 22 months, further studies are expected.

Pulmonary Radiological Manifestations of Humoral and Combined Immunodeficiencies in a Tertiary Pediatric Center.

Respiratory diseases are considered as significant causes of morbidity and mortality in primary immunodeficiencies. This study aimed to reveal the radiologic patterns of thoracic involvement in these disorders. A total of 58 patients, including 38 cases with combined cellular-humoral and 20 cases with humoral immunodeficiencies, were enrolled in this study. The "combined" group consisted of 12 cases with severe combined immunodeficiency (SCID) and 26 cases with combined immunodeficiency. The "humoral" group included seven patients with Hyper IgM syndrome (HIGMs), seven cases with common variable immunodeficiency (CVID), three patients with X-linked agammaglobulinemia, and three patients with other types of humoral primary immunodeficiencies (PIDs). The mean age of patients at the time of evaluation was 3.3±3.8 and 5.3±3.9 years in combined and humoral groups, respectively. The findings of chest X-rays and CT scans were interpreted and compared. There was a significant difference for alveolar opacification between combined and humoral immunodeficiencies (58% vs. 30%). The bronchopneumonia-like pattern was detected as a significant finding in patients with SCID (42%) and HIGMs (43%). Atrophy of the thymus was detected significantly often in cases of SCID (67%). Two patients with CVID and lipopolysaccharide-responsive and beige-like anchor protein deficiency showed parenchymal changes of granulomatous lymphocytic interstitial lung disease. No significant difference was detected for bronchiectasis, bronchitis/bronchiolitis patterns, pleural effusion, and thoracic lymphadenopathy. Distinct subtypes of primary immunodeficiency may provoke differing and comparable radiological patterns of thoracic involvement; which can clue the clinician and radiologist to the diagnosis of the disease.

Study protocol of a randomized controlled clinical trial investigating the effects of omega-3 supplementation on endothelial function, vascular structure, and metabolic parameters in adolescents with type 1 diabetes.

BACKGROUND: Type 1 diabetes is a main health burden with several related comorbidities. It has been shown that endothelial function, vascular structure, and metabolic parameters are considerably disrupted in patients with type 1 diabetes. Omega-3 as an adjuvant therapy may exert profitable effects on type 1 diabetes and its complications by improving inflammation, oxidative stress, immune responses, and metabolic status. Because no randomized clinical trial has examined the effects of omega-3 consumption in children and adolescents with type 1 diabetes; the present study aims to close this gap. METHODS: This investigation is a randomized clinical trial, in which sixty adolescents with type 1 diabetes will be randomly assigned to receive either omega-3 (600 mg/day) or placebo capsules for 12 weeks. Evaluation of anthropometric parameters, flow-mediated dilation (FMD) as an endothelial function marker, carotid intima-media thickness (CIMT) as a vascular structure marker, proteinuria, biochemical factors including glycemic and lipid profile, blood urea nitrogen (BUN), creatinine, high-sensitivity C-reactive protein (hs-CRP), and erythrocyte sedimentation rate (ESR), as well as blood pressure will be done at the baseline and end of the trial. Also, dietary intake and physical activity will be assessed throughout the study. Statistical analysis will be performed using the SPSS software (Version 24), and P < 0.05 will be considered statistically meaningful. DISCUSSION: It is hypothesized that omega-3 supplementation may be beneficial for the management of type 1 diabetes and its complications by reducing inflammation and oxidative stress and also modulating immune responses and glucose and lipid metabolism through various mechanisms. The present study aims to investigate any effect of omega-3 on patients with type 1 diabetes. ETHICAL ASPECTS: This trial received approval from Medical Ethics Committee of Iran University of Medical Sciences, Tehran, Iran (IR.IUMS.REC.1400.070). TRIAL REGISTRATION: Iranian Registry of Clinical Trials IRCT20210419051010N1 . Registered on 29 April 2021.

Cerebral venous thrombosis in a child with inflammatory bowel disease.

BACKGROUND: Inflammatory bowel disease (IBD) has both intestinal and extraintestinal manifestations. Inflammatory bowel disease is a known risk factor for cerebral venous thrombosis (CVT) in adults and children. The precise mechanism of the thrombotic event is unclear in IBD patients. We report a case of ulcerative colitis with CVT admitted for acute relapse. CASE PRESENTATION: A 12-year-old boy, who was a known case of ulcerative colitis since 12 months ago, was admitted to our hospital because of bloody diarrhea and recurrent colicky abdominal pain. On the third day of admission, the patient complained of severe headache. The level of consciousness decreased gradually during 12 hours and became aphasic later. One episode of tonic-clonic seizure happened 18 hours after the onset of headache. Neurologic examination showed right hemiparesis. Physical examinations, including blood pressure and fundoscopy were unremarkable on the last admission. Brain computed tomography (CT) showed intraparenchymal hemorrhage in the left temporal lobe with asymmetric increased density in the left lateral sinus. The magnetic resonance imaging (MRI) results revealed abnormal hyperintense signal in the left lateral sinus in T1WI and T2WI, which is compatible with thrombosis (loss of signal) in magnetic resonance venography (MRV). Low-molecular-weight heparin was administered according to consultation with a hematologist and continued post-discharge. The patient's condition improved slowly, and neurologic evaluation was normal after three months. CONCLUSION: Cerebrovascular events, such as cerebral venous thrombosis (CVT) or cerebral arterial infarction (CAI), are rare extraintestinal manifestations of PIBD but probably the most common forms of thromboembolism in children. Probably, treatment of CVT with anticoagulants is the best way of management. A comprehensive study is essential to understand the choice, efficacy, duration, and primary and secondary prophylaxis protocol with anticoagulants.

The effect of spiritual care on quality of life of patients with amputation caused by diabetes type 2: a clinical trial.

OBJECTIVES: This study aimed to investigate effect of a spiritual care on quality of life of patients with amputation caused by diabetes type 2. METHODS: The current study was a clinical trial. Fifty four patients with amputation caused by diabetes type 2 referred to Al-Zahra hospital at Isfahan was allocated to two case and control groups. Spiritual care training including transcendental meditation (T.M) technique was established for case group. Participants in case group performed four weeks of meditation technique following participating in sessions of meditation technique training. Data gathering was done using a standard tool to assess quality of life in patients with diabetes (diabetes quality of life: DQOL). Data was analyzed using SPSS software. RESULTS: Mean score of quality of life in the four areas of quality of life was not significantly different among case and control groups at baseline, however, mean score of quality of life in case group (2.25 ± 0.56) was significantly better than control group (2.52 ± 0.38) after intervention (p<0.001). CONCLUSIONS: Given findings of the study, it seems that spiritual care can improve quality of life of patients with amputation caused by diabetes type 2.

Cerebral Infiltrative Lesion and Chronic Clinical Course of the Rosai-Dorfman Disease.

Rosai-Dorfman disease (RDD) is a rare disorder of an unknown etiology, characterized by a benign histiocytic proliferation in the lymph nodes, as well as the extranodal sites. Painless bilateral lymphadenopathy is the classic presentation of RDD in the majority of patients. The exteranodal disease involves the skin, soft tissues, bones, the genitourinary system, the lower respiratory tract, and the central nervous system. A seven-year-old boy was referred to our hospital with left parietal swelling, headache, fever, imbalance, weight loss, and speech and walking impairments. In early examinations, he showed a hyposignal infiltrative lesion in the lateral ventricle and the choroid plexus, expanding to the subcortical white matter of the bilateral temporo-occipital areas. After surgery and sampling, he was diagnosed with cerebral RDD. According to his history, he had bilateral cervical lymphadenopathy at the age of two years, femoral soft tissue involvement at the age of three, and a skin disorder that improved with local treatments at the age of five. However, at the time of referral to the hospital, there were no other symptoms in other areas, except for brain symptoms. In the differential diagnosis of brain lesions with specific borders in high-contrast radiological views, the probability of RDD should be considered, similar to meningioma. The presence of painless and extensive bilateral cervical lymphadenopathy can improve the diagnosis of this disease. Isolated brain involvement in RDD is very rare, and it can be seen in less than 5% of cases. Nevertheless, by early diagnosis and intervention, the risk of complications is reduced, and the prognosis is improved.
