Vasculitis reumatoidea: una manifestación poco habitual. Presentación de tres casos clínicos y revisión de la literatura

La vasculitis reumatoidea es una complicación sistémica y poco frecuente de la Artritis Reumatoidea. Si bien su incidencia ha descendido en los últimos años con el advenimiento de las nuevas terapias inmunosupresoras y biológicas, continua teniendo una alta morbimortalidad. Predomina en el sexo masculino, en pacientes seropositivos y con un largo período de la enfermedad establecida. Requiere de alta presunción diagnostica, siendo el compromiso cutáneo y nervioso periférico el más frecuente. La biopsia de nervio o piel es requerida habitualmente para su diagnóstico. El tratamiento se basa en corticoides e inmunosupresores. Presentamos tres casos clínicos y realizamos una revisión de la literatura.

Rheumatoid vasculitis is a rare systemic complication of rheumatoid arthritis. Although its incidence has decreased in recent years with the advent of new immunosuppressive and biological therapies, it continues to have a high morbidity and mortality. It predominates in males, in seropositive patients and with a long period of established disease. It requires high diagnostic presumption, with skin and peripheral nervous involvement being the most affected. Nerve or skin biopsy is usually required for diagnosis. Treatment is based on corticosteroids and immunosuppressants. We present three clinical cases and carry out a review of the literature.

Secondary oral syphilis presenting as a tumor-like lesion on the lower lip

ABSTRACT This study presents a case of atypical manifestation of secondary syphilis. Diagnosis was initiated prompted by the patient's complaint of a lower lip lesion, present for three months, resembling a malignant neoplasm. The lesion, a 3 cm (diameter) ulcerated nodule, arising from conjunctive tissue, raised concern. However, further physical examination revealed additional clinical features, including cervical micropolyadenopathy and erythematous skin lesions, prompting a reevaluation of the diagnosis, most likely secondary syphilis. These findings led to a serological investigation, which, ultimately, confirmed the diagnosis of syphilis. The case underscores the importance of recognizing syphilis as a formidable imitator, posing challenges in establishing differential diagnoses of mucocutaneous diseases.

Research progress on the manifestations and prognosis of neonatal lupus erythematosus in various systems / 中国当代儿科杂志

Neonatal lupus erythematosus (NLE) is caused by the transmission of maternal anti-Ro/SSA antibodies, anti-La/SSB antibodies, and other autoantibodies to the fetus through the placenta. Usually, with the disappearance of autoantibodies in the children's body, abnormal changes in the mucocutaneous, blood system, and digestive system can spontaneously subside, but the damage to various systems caused by autoantibodies may persist for a long time. This article provides a comprehensive review of the manifestations and prognosis of NLE in various systems, including mucocutaneous, blood system, circulatory system, nervous system, digestive system, respiratory system, aiming to provide reference for clinical work.

Cutaneous manifestations of COVID-19 patients in a Hospital in São Paulo, Brazil, and global literature review

Abstract Background: Since the beginning of the COVID-19 pandemic, a myriad of cutaneous manifestations have been described in association with this viral infection. However, in Latin America, this kind of data is still scarce. Objective: In this sense, the goal of this study was to describe the dermatological findings observed during SARS-CoV-2 infection, in a Brazilian Hospital. Methods: This is a cross-sectional, retrospective and descriptive study of 50 cases of new-onset dermatologic symptoms in patients with COVID-19, treated at Hospital Sírio-Libanês, from February to June 2020. Results: The patients (n = 50) were classified into 6 groups, according to the elementary lesions and the statistical analysis was performed. The most common cutaneous lesions were maculopapular eruptions (44%), necrosis, purpura, and livedo (32%), urticarial lesions (12%), pseudochilblains (4%) and papular-vesicular eruption (4%). In 46% of the patients the cutaneous lesions occurred in association with other symptoms, such as pruritus (38%), pain and burning sensation (8%). Lower limbs were affected in 44% of the cases, followed by the trunk (38%), upper limbs (24%) and face (14%). Cutaneous lesions were mostly found after other COVID-19 systemic symptoms, with a mean period between the viral syndrome and cutaneous signs of 5 days (SD = 6.1 days). Study limitations: It is a small sample, in a single-center study, with patients exclusively from a private Hospitals. Conclusions: Patients in Brazil have the same proportion of lesions as revealed in other studies in Europa. The compiled data is essential for a better understanding of cutaneous manifestations deemed secondary to COVID.

Acute pancreatitis caused by Systemic Lupus Erythematosus activity: A case report and literature review / Pancreatitis aguda por actividad del lupus eritematoso sistémico: Reporte de caso y revisión de la literatura

A 32-year-old woman with systemic lupus erythematosus came to the rheumatology outpatient clinic reporting abdominal pain for a week, along with fever, arthralgias, myalgias, alopecia, asthenia and dyspnea on exertion over the last two months. She was hypotensive and tachycardic, requiring admission to the intensive care unit. She was diagnosed with lupus-related acute pancreatitis, an unusual complication occurring in less than 1% of cases. Most cases are mild and self-limited; however, severe and life-threatening events with multiple organ failure are possible. This article is a case report of lupus-related critical acute pancreatitis, and a literature review.

Innominate Artery Cannulation for Proximal Aortic Surgery

ABSTRACT Introduction: The aim of this study was to evaluate the efficacy and safety of innominate artery cannulation strategy with side-graft technique in proximal aortic pathologies. Methods: A total of 70 patients underwent innominate artery cannulation with a side graft for surgery on the proximal aorta from 2012 to 2020. There were 46 men and 24 women with an average age of 56±13 years. The indications for surgery were type A aortic dissection in 17 patients (24.3%), aortic aneurysm in 52 patients (74.3%), and ascending aorta pseudoaneurysm in one patient (1.4%). The innominate artery was free of disease in all patients. Hypothermic circulatory arrest with antegrade cerebral perfusion was utilized in 60 patients (85.7%). Three patients had previous sternotomy (4.2%). The most common surgical procedure was ascending aorta with hemiarch replacement in 34 patients (48.5%). Results: The mean cardiac ischemia and cardiopulmonary bypass times were 116+46 minutes and 164+56 minutes, respectively. Mean antegrade cerebral perfusion time was 27+14 minutes. The patients were cooled between 22°C and 30°C during surgery. Thirty-day mortality rate was 7.1% (five patients). One patient (1.4%) had stroke, one patient (1.4%) had temporary neurologic deficit, and eight patients (11.4%) had confusion and agitation that resolved completely in all cases. There was no local complication or arterial injury. Conclusion: Cannulation of the innominate artery with side graft is safe and effective for both cardiopulmonary bypass and antegrade cerebral perfusion. This technique provides satisfactory neurologic outcomes for proximal aortic surgery.

Anti-SSA/SSB-negative primary Sjögren's syndrome showing different clinical phenotypes: a retrospective study of 934 cases

Abstract Background Currently, only a few studies have described the general characteristics of patients with primary Sjögren's syndrome (pSS) who tested negatives for anti-SSA and anti-SSB antibodies. We aimed to further investigate the clinical characteristics of these patients in a large sample. Methods Data from patients with pSS who were treated at a tertiary hospital in China between 2013 and 2022 were retrospectively analyzed. Clinical characteristics of the patients were compared between those with and without anti-SSA and anti-SSB antibody negativity. Factors associated with anti-SSA and anti-SSB negativity were identified by logistic regression analysis. Results Overall, 934 patients with pSS were included in this study, among whom 299 (32.0%) tested negative for anti-SSA and anti-SSB antibodies. Compared with patients testing positive for anti-SSA or anti-SSB antibodies, that testing negative for the two antibodies had a lower proportion of females (75.3% vs. 90.6%, p < 0.001) and thrombocytopenia (6.7% vs. 13.6%, p = 0.002), but a higher proportion of abnormal Schirmer I tests (96.0% vs. 89.1%, p = 0.001) and interstitial lung disease (ILD) (59.2% vs. 28.8%, p = 0.001). Anti-SSA and anti-SSB negativity was positively associated with male sex (odds ratio [OR] = 1.86, 95% confidence interval [CI]: 1.05, 3.31), abnormal Schirmer I tests (OR = 2.85, 95% CI: 1.24, 6.53), and ILD (OR = 2.54, 95% CI: 1.67, 3.85). However, it was negatively related to thrombocytopenia (OR = 0.47, 95% CI: 0.24, 0.95). Conclusion Approximately one third of pSS patients had anti-SSA and anti-SSB negativity. pSS patients testing negative for anti-SSA and anti-SSB showed a higher risk of abnormal Schirmer I tests and ILD, but a lower risk of thrombocytopenia.

Research progress of nervous system damage in Pompe disease / 中国当代儿科杂志

Pompe disease, also known as glycogen storage disease type Ⅱ, is a rare autosomal recessive disease. With the application of enzyme replacement therapy, more and more patients with Pompe disease can survive to adulthood, and nervous system-related clinical manifestations gradually emerge. Nervous system involvement seriously affects the quality of life of patients with Pompe disease, and a systematic understanding of the clinical manifestations, imaging features and pathological changes of nervous system injury in Pompe disease is of great significance for the early identification and intervention of Pompe disease. This article reviews the research progress of neurological damage in Pompe disease.

Clinical and imaging features of eight cases of Ewing sarcoma of the jaw / 华西口腔医学杂志

OBJECTIVES@#This study investigate the clinical and imaging features of Ewing sarcoma (ES) of the jaw.@*METHODS@#Eight cases of pathologically diagnosed ES of the jaw from January 2010 to June 2022 were included in the study. Clinical and radiological features were retrospectively analyzed.@*RESULTS@#Among the eight cases, the mean age at onset was 29.4 years, and the male to female ratio was 7∶1. The predilecting site was the posterior part of mandible, accounting for 75% of the cases. The lesions often exhibited early numbness of the lower lip and lymphadenopathy. The main radiographic manifestation of mandibular lesions was ill-defined radiolucency, mixed with fibrous or brush-like tumor matrix, and soft tissue mass. The maxillary ES lesions mainly presented as lytic bone destruction accompanied by adjacent soft tissue mass. Periosteal ossification was rarely seen.@*CONCLUSIONS@#The clinical and imaging characteristics of ES in the jaw are helpful for its diagnosis.

Emergence Of Dengue Virus Type 4 During COVID-19 Pandemic In Patients Admitted to a Teaching Hospital In Malaysia (Peningkatan virus denggi serotip keempat semasa pandemik COVID-19 pada pesakit yang dimasukkan ke hospital pengajar di Malaysia) / Jurnal Sains Kesihatan Malaysia

@#Prior to COVID-19, dengue was an important public health problem in Malaysia. Due to the movement control order imposed by the Malaysian government to curb the COVID-19 transmission, a study predicted that mosquito-borne diseases would increase during lockdown and partial lockdown seasons. Thus, this study aims to determine the current situation of dengue incidence during the pre-COVID-19 pandemic (2019) and during the COVID-19 pandemic (2020 and 2021). We compared the number of laboratory-confirmed cases in the pre-COVID19 year (2019) and during the COVID-19 pandemic (2020 and 2021). In addition to that, we characterized the clinical manifestation, dengue serotype and viremia levels of dengue patients that were admitted to the Hospital Cancelor Tuanku Muhriz. We found a significant decrease in the number of laboratory-confirmed cases between COVID-19 pandemic and the pre-covid period (p2020=0.064; p2021<0.001). In this study, we found DENV 4 serotype was the most common serotype in dengue patients admitted to our hospital. There was no significant correlation between DENV serotype/viremia level with clinical manifestation of dengue fever and dengue with warning signs. However, patients infected with DENV4 had the highest viral load compared to patients infected with other serotypes. We also found high viremia levels were significantly associated with the febrile phase.

Intrahepatic and extrahepatic clinical manifestations and treatment progress for hepatitis type E / 中华肝脏病杂志

Hepatitis type E virus (HEV) is one of the main causes of acute hepatitis globally and has thus gained attention as a public health issue. The diverse clinical manifestations of hepatitis type E are typically acute and self-limiting with mild symptoms, but populations with underlying liver disease or immunocompromised patients can have severe and chronic symptoms. Severity and chronicity can arise and manifest as fulminant hepatitis, chronic hepatitis, or even hepatic failure. HEV infection-induced hepatic failure (acute-on-chronic liver failure), based on the different backgrounds of chronic liver disease, is a clinical phenotype of severe HEV infection that requires attention. In addition, HEV infection can exhibit extrahepatic clinical manifestations of multi-system and organ involvement like neurological diseases (Guillain-Barré syndrome), renal diseases (membranous/membranous proliferative glomerulonephritis, cryoglobulinemia), and blood diseases (thrombocytopenia). At home or abroad, there are no antiviral drugs approved, particularly for HE treatment. Since most acute HE can resolve spontaneously, no special treatment is required clinically. However, in patients with severe or chronic HE, ribavirin (RBV) monotherapy and/or pegylated interferon-combination therapy have achieved certain antiviral effects. Combined small-molecule drugs and RBV have been attempted to treat HEV, but high-level evidence-based treatment is still lacking. Thus, new, highly effective anti-HEV drugs are clinical priorities to address these concerns. Severe and chronic HEV infections' clinical phenotype, early detection, mechanism, intervention, and outcome need additional study.

Analysis of factors affecting the clinical features of familial exudative vitreoretinopathy / 中华眼底病杂志

Objective:To observe and investigate the related factors that might affect clinical features of familial exudative vitreoretinopaty (FEVR) patients.Methods:A retrospective chart study. From January 2012 and December 2021, 42 patients with 84 eyes with a diagnosis of FEVR from Department of Ophthalmology, Peking University People's Hospital were included in the study. The patients came from 42 separate families. There were 31 males and 11 females, with an average age of first diagnosis was 16.6±33.7 months. There were 21 patients referred from other hospitals for the fundus disease found in eye screening after birth, 21 patients were first seen in our hospital. There were 4 and 38 premature and full-term infants, respectively. Two patients with a positive family history of FEVR. All patients are FEVR stages 1-5. The wide-angle digital pediatric retinal imaging system after general anesthesia for fluorescein fundus angiography (FFA) examination were performed for patients aged <5 years. If patients ≥ 5 years old, routine FFA examination was performed. Sixty-eight first-degree relatives from 28 families undergo routine fundus examinations and FFA examination. Genetic examination was performed for 26 families, including 26 probands and 57 first-degree relatives. Genetic examination were performed on gene the coreceptor of low density lipoprotein receptor-associated protein 5 ( LRP5), Wnt receptor coiled protein 4 ( FZD4), Norrie disease ( NDP), tetraporin 12 ( TSPAN12), catenin β1 ( CTNNB1) genes known to be involved in FEVR. The clinical features and the genotype of FEVR were observed in relation to the clinical phenotype. Results:Among the 42 patients, 13 patients were first observed by strabismus and nystagmus, with the median age of 12 months. Eight patients were complained non-chasing or vision-related symptoms. Among the 84 eyes, FEVR stage 1 or 2, 3 or 4, and 5 were 50 (59.5%, 50/84), 31 (36.9%, 31/84), and 3 (3.6%, 3/84) eyes, respectively. Among the 23 patients who were > 3 months at first diagnosis, 16 patients had at least one eye severer than stage 3 (69.6%, 16/23). Of the 68 first-degree relatives, 22 (32.4%, 22/68) had FEVR-like changes. Among the 26 families that underwent genetic detection, 13 families (50%, 13/26) of 16 variants of FEVR-related genes were detected, of which 10 mutations of LRP5 gene were the most common. There were 10 families with single gene mutations, including 6, 2 and 2 families of LRP5, FZD4 and CTNNB1 genes, respectively. One family of LRP5 gene mutations were compound heterozygous mutations, 1 family with LRP5 gene mutaition combined with NDP gene mutation, and 1 family with LRP5 and TSPAN12 gene mutation. Among the proband with FEVR pathogenic genes, 6 cases with similiar stage of both eyes, and 7 cases with inconsistent disease stages, and there was no obvious correlation between gene mutations and clinical phenotypes. Conclusion:In addition to the age of first diagnosis, no exact factors affecting the clinical manifestations of FEVR are found, and the association between clinical phenotypic and genetic heterogeneity still needs to be further explored.

Analysis of clinical features of seven patients with granular parakeratosis after benzalkonium chloride exposure / 中华皮肤科杂志

Objective:To summarize clinical manifestations and histopathological features of granular parakeratosis (GP) after exposure to benzalkonium chloride.Methods:A retrospective analysis was performed on 7 GP cases with a history of benzalkonium chloride exposure in the Department of Dermatology at Wuhan No.1 Hospital from April to August 2022. Data were collected on the general condition, skin lesion manifestations, pathological examination, treatment, and follow-up of the patients, and retrospectively analyzed.Results:The 7 adult patients with GP typically presented with erythema and brown scales in the intertriginous area, exhibiting an annular distribution pattern. All the 7 patients reported recent exposure to disinfectants containing benzalkonium chloride. A total of 10 skin biopsies were taken from the 7 patients. Histopathological examination showed characteristic hyperkeratosis and fine blue-gray parakeratotic granules in the stratum corneum. All skin lesions improved 1 month after cessation of exposure to benzalkonium chloride.Conclusion:GP has a distinct clinical pattern and histopathological manifestations, and a history of exposure to benzalkonium chloride can be helpful for the diagnosis of GP.

Clinical characteristics and treatment of eight cases of pemphigus/bullous pemphigoid complicated by herpes simplex virus infection / 中华皮肤科杂志

Objective:To retrospectively analyze clinical characteristics and treatment of pemphigus/bullous pemphigoid (BP) complicated by herpes simplex virus (HSV) infection.Methods:Inpatients with pemphigus/BP complicated by HSV infection were collected from Wuhan No.1 Hospital from 2016 to 2021, and their clinical characteristics, treatment and follow-up results were retrospectively analyzed.Results:Among the 8 patients with pemphigus/BP complicated by HSV infection, there were 2 males and 6 females, and their age was 50.6 ± 8.3 years. Five of them were diagnosed with pemphigus vulgaris (PV), 1 with pemphigus foliaceus (PF), and 2 with BP. Seven were infected with HSV-1, and 1 with HSV-2. All the 8 patients were given systemic glucocorticoids and immunosuppressive agents for the treatment of pemphigus or BP, and were admitted to the hospital due to resistance to the treatment. Seven patients presented with exacerbation or recurrence of primary lesions, and 1 presented with enlarged lesions all over the body. HSV infection-induced lesions were located on the trunk in 4 cases, on the oral mucosa in 4, on the scalp in 3, and on the face in 2; lesions mainly manifested as irregular erosions with blood crusts, and some centrally umbilicated pustules; 7 patients had obvious pain at the lesional sites. During HSV infection, anti-desmoglein 1 antibody levels decreased in all the 6 patients with pemphigus, and anti-desmoglein 3 antibody levels decreased in 4 of the 5 patients with pemphigus vulgaris; anti-BP180 antibody levels decreased in 1 patient with BP, but increased in the other one with BP. After antiviral therapy at adequate doses for adequate durations (7- to 14-day treatment with valacyclovir alone or in combination with ganciclovir), HSV infection was controlled, the autoimmune bullous skin disorder intensity scores decreased compared with those before the antiviral therapy, and pain was significantly relieved in all the patients. No dose adjustment of glucocorticoids or other immunosuppressive agents was made during antiviral therapy in all patients.Conclusion:HSV infection should be considered when patients with pemphigus/BP suffer from recurrence or exacerbation and poorly respond to conventional treatment; for patients with pemphigus/BP complicated by HSV infection, systemic antiviral therapy at adequate doses can be used to control the disease condition without modifying the conventional immunosuppressive regimen.

Progress in diagnosis and treatment of retinal vasoproliferative tumor / 中华实验眼科杂志

Retinal vasoproliferative tumor (RVPT) is a rare benign glial proliferative tumor of unknown origin.The fundus is typically characterized by yellow or pink tumor-like lesions of the retina around the inferior temporal region, often accompanied by subretinal fluid, exudation, epiretinal membrane and other complications.Typical RVPT showed high fluorescence on fundus fluorescein angiography, diffuse leakage in venous phase and late stage, uneven middle or high reflection signal on B-ultrasound, and it was not difficult to diagnose combined with fundus changes.Atypical RVPT should be differentiated from retinal capillary hemangioma caused by von Hippel-Lindau disease, Coats disease and familial exudative vitreoretinopathy.The pathogenesis of RVPT is unclear, but histopathology shows that it may be the reactive proliferation of glial cells.At present, there is no unified treatment plan for RVPT, mainly cryotherapy, laser photocoagulation, local radiotherapy, transpupillary thermal therapy or photodynamic therapy for tumor.For patients with vitreous hemorrhage, vitreoretinal surgery is feasible.This article reviewed the clinical features, diagnosis and differential diagnosis, pathology and pathogenesis, and treatment progress of RVPT.

Analysis of complicated virus infection and clinical characteristics in 100 infants with pertussis / 中国小儿急救医学

Objective:To investigate the complicated virus infection of infants with pertussis and its effect on the disease.Methods:From January 2019 to March 2020, a total of 100 hospitalized infants with pertussis were admitted to the Second Affiliated Hospital of Medical College of Shantou University, nasopharyngeal swabs were collected for detection of ten pathogens including pertussis, namely respiratory syncytial virus(RSV), parainfluenza virus(PIV), bordetella pertussis (BP), human rhinovirus(HRV), human bocavirus(HBoV), human metapneumovirus(hMPV), influenza B virus (INF-B), adenovirus, influenza A virus and cytomegalovirus(CMV). According to the results of pathogen detection, all infants were divided into single detection group of BP(single detection group) and co-detection group of BP combined with viruses(co-detection group). The clinical data of the two groups were retrospectively analyzed and compared to explore the differences of clinical characteristics and its impact on the course of disease.Results:Among 100 cases, there were 54(54.0%) boys and 46(46.0%)girls.The age ranged from 28 days to 2 years and 5 months, with a median age of 3.5 months.Fifty-six cases were classified as single detection group, while 44 cases were included into co-detection group.Among infants in co-detection group, fourteen cases were co-infected with CMV(31.8%, 14/44), seven cases with HRV(15.9%, 7/44), seven cases with PIV(15.9%, 7/44), four cases with RSV(9.1%, 4/44), one case with hMPV(2.2%, 1/44), eight cases with CMV+ HRV(18.2%, 8/44), one case with HRV+ HBoV (2.2%, 1/44), one case with CMV+ PIV(2.2%, 1/44)and one case with CMV+ PIV+ INF-B(2.2%, 1/44). The number of infants in the single detection group who had cyanosis before treatment, requiring repiratory support, PICU admission, severe pneumonia or abnormal myocardial enzymes were higher than those in the co-detection group( P<0.05), while the months of age were lower than that in the co-detection group( P<0.05). When comparing the clinical characteristics of infants over three months of age, only the number of cases of combined cyanosis before treatment and the number of days in hospital were higher in the single detection group than those in the co-detection group ( P<0.05), no statistically significant differences were found in the other clinical characteristics between the two groups( P>0.05). Conclusion:The cases of infants requiring repiratory support, complicated with severe pneumonia or abnormal myocardial enzymes in the single detection group are higher than those in the co-detection group, which may be attributed to the small age of months.

Clinical analysis of 8 cases of transverse testicular ectopia / 中华实用儿科临床杂志

Objective:To study the clinical manifestations, diagnostic methods and therapeutic outcomes of transverse testicular ectopia (TTE).Methods:Clinical data of 8 cases of TTE treated in the Department of the First Urologic Surgery, Xinxiang Central Hospital and Department of Pediatric Surgery, the First Affiliated Hospital of Zhengzhou University from May 2004 to November 2018 were retrospectively analyzed.Clinical manifestations, diagnostic methods, surgical treatment and follow-up results of TTE were summarized.Results:The age of 8 cases of TTE was 1 year 5 months to 5 years.Among the 8 cases of TTE, 6 cases were involved with the left side and 2 cases with the right side.All patients were admitted due to scrotal emptiness.Three cases were combined with persistent Müllerian duct syndrome (PMDS) and 1 case combined with hypospadias.Preoperative diagnosis of TTE was definitely made in 5 cases, involving 4 cases diagnosed by ultrasound and 1 case diagnosed by magnetic resonance imaging.Laparoscopy was performed in 2 cases, including 1 case treated with laparoscopic scrotopexy, and the other one transferred to an open surgery of trans-septal orchiopexy due to poor development of the spermatic cord.Open surgery was performed in 6 cases, including 1 case with bilateral testicular fixation in the ipsilateral scrotum due to adhesion of spermatic cord closely, and 5 cases with trans-septal orchiopexy.Müllerian ducts residues were excised during surgery in 3 cases combined with PMDS.Postoperative wound infection or hematoma was not reported in all cases.Orchiepididymitis and the involvement of contralateral testes occurred in 1 case treated with trans-septal orchiopexy at 11 months postoperatively, which were relieved after anti-inflammatory treatment.All cases were postoperatively followed up for 3-48 months, and the development and blood supply of bilateral testes were detected normal by ultrasonography.Postoperative testicular atrophy was not reported.Conclusions:The possibility of TTE should be considered in patients with unilateral cryptorchidism combined with contralateral inguinal mass.Ultrasonography is preferred to the diagnosis of TTE.Laparoscopic surgery plays an important role in the diagnosis and treatment of TTE, which is helpful to identify abnormalities in the Müllerian duct structure.

Clinical analysis of 50 children with superior vena cava syndrome combined with malignant tumors / 中华实用儿科临床杂志

Objective:To summarize and analyze the clinical characteristics, treatment and prognosis of superior vena cava syndrome (SVCS) with malignant tumors in children, and to improve the understanding of its clinical management.Methods:Clinical data of 50 children with SVCS combined with malignant tumors treated in the First Affiliated Hospital of Zhengzhou University from November 2010 to May 2022 were analyzed retrospectively.The pathological types, clinical manifestations, imaging examination, treatment and prognosis were summarized.The overall survival (OS) rate and event-free survival (EFS) rate were evaluated by Kaplan-Meier method.Results:Among the 50 cases, 38 were males and 12 were females, with a male/female ratio of 3.2∶1.0.The median onset was 12.5 (8.0, 14.5) years, and the most common onset occurred in adolescence (66.0%, 33/50). Cough (80.0%, 40/50) was the most common clinical manifestation, followed by face and neck edema (66.0%, 33/50), chest tightness (56.0%, 28/50) and dyspnea (50.0%, 25/50). All the 50 cases were confirmed by histopathological examination, 39 cases(78.0%) were diagnosed as non-Hodgkin′s lymphoma (NHL). NHL was the most common malignant tumor, of which T-lymphoblastic lymphoma (T-LBL) accounted for 74.4%(29/39). All the 50 cases were examined by CT examination, involving 42 cases (84.0%) detected with mediastinal masses.Pleural effusion (86.0%, 43/50) and pericardial effusion (70.0%, 35/50) were common imaging findings.The 3-year OS rate and EFS rate of them were 59.7% and 57.9%, respectively.The 3-year OS rate and EFS rate of the 39 children with NHL were 62.9% and 60.9%, respectively.Conclusions:Children with malignant tumors complicated with SVCS are featured by the acute onset, rapid progress and poor prognosis.NHL is the most common cause, especially T-LBL.Cough, edema of face and neck, chest tightness and dyspnea are common clinical manifestations.Early detection and treatment contribute to save children′s lives.
