Primary congenital lymphedema: Milroy disease: the first case observed in the Department of Pediatrics at the University Hospital Yalgado Ouedraogo, Ouagadougou.

Congenital lymphedema is the accumulation of lymphatic fluid in the child's interstitial spaces. Milroy disease is a rare, hereditary, autosomal dominant condition showing incomplete penetrance. We report the case of a 7-year old little girl with Milroy disease examined for erysipelas on congenital big right leg. A family history of large congenital member existed. Physical examination showed big oedematous right leg painful to palpation, with skin lichenification and erysipelas. Paraclinical assessment objectified cutaneous lymphedema with vascular involvement suggestive of ectasia of the right saphenous vein. Female karyotype showed no abnormalities, despite the small chromosomal rearrangements. Treatment was based on physiotherapy, bandages, compression stockings and psychotherapy. This first case in Burkina Faso testifies to the rarity of the pathology but especially to the diagnostic difficulties related to the inadequacy of paraclinical investigations.

Desquamative erythrodermia.

Paraneoplastic dermatoses are a spectrum of cutaneous manifestations which may precede, coincide with or follow the diagnosis of cancer. Our study aims to remind clinicians that desquamative erythrodermia is a form of paraneoplastic dermatosis which may occur during hematologic malignancies. Hence the importance of a complete assessment to identify a neoplastic process in the presence of these clinical signs and especially when they are suspect.

A rare case of iron-pill induced gastritis in a female teenager: A case report and a review of the literature.

The treatment of iron-deficiency anemia with oral iron supplements can present side-effects on the GI tract mucosa including necrosis, ulceration, or ischemia. The particular endoscopic findings and the histopathological exam will establish the diagnosis of erosive gastritis with iron deposits in the gastric mucosa.

Risk factors and a prediction model for lower limb lymphedema following lymphadenectomy in gynecologic cancer: a hospital-based retrospective cohort study.

Lower limb lymphedema (LLL) is a chronic and incapacitating condition afflicting patients who undergo lymphadenectomy for gynecologic cancer. This study aimed to identify risk factors for LLL and to develop a prediction model for its occurrence.

Pathological manifestations in lymphatic filariasis correlate with lack of inhibitory properties of IgG4 antibodies on IgE-activated granulocytes.

Helminth parasites are known to be efficient modulators of their host's immune system. To guarantee their own survival, they induce alongside the classical Th2 a strong regulatory response with high levels of anti-inflammatory cytokines and elevated plasma levels of IgG4. This particular antibody was shown in different models to exhibit immunosuppressive properties. How IgG4 affects the etiopathology of lymphatic filariasis (LF) is however not well characterized. Here we investigate the impact of plasma and affinity-purified IgG/IgG4 fractions from endemic normals (EN) and LF infected pathology patients (CP), asymptomatic microfilaraemic (Mf+) and amicrofilaraemic (Mf-) individuals on IgE/IL3 activated granulocytes. The activation and degranulation states were investigated by monitoring the expression of CD63/HLADR and the release of granule contents (neutrophil elastase (NE), eosinophil cationic protein (ECP) and histamine) respectively by flow cytometry and ELISA. We could show that the activation of granulocytes was inhibited in the presence of plasma from EN and Mf+ individuals whereas those of Mf- and CP presented no effect. This inhibitory capacity was impaired upon depletion of IgG in Mf+ individuals but persisted in IgG-depleted plasma from EN, where it strongly correlated with the expression of IgA. In addition, IgA-depleted fractions failed to suppress granulocyte activation. Strikingly, affinity-purified IgG4 antibodies from EN, Mf+ and Mf- individuals bound granulocytes and inhibited activation and the release of ECP, NE and histamine. In contrast, IgG4 from CP could not bind granulocytes and presented no suppressive capacity. Reduction of both the affinity to, and the suppressive properties of anti-inflammatory IgG4 on granulocytes was reached only when FcγRI and II were blocked simultaneously. These data indicate that IgG4 antibodies from Mf+, Mf- and EN, in contrast to those of CP, natively exhibit FcγRI/II-dependent suppressive properties on granulocytes. Our findings suggest that quantitative and qualitative alterations in IgG4 molecules are associated with the different clinical phenotypes in LF endemic regions.

Cyclosporin A Reversed Chemoresistance of a Patient with Pure Red Cell Aplasia Secondary to Thymoma.

This case study reports on a patient who relapsed with thymoma (mixed type) nine years after tumor resection. After four courses of rescue chemotherapy (docetaxel and cisplatinum), the patient was further diagnosed with pure red cell aplasia. It was noticed that cyclosporin A (CsA), which was administered to treat aplasia, could reverse chemoresistance. Its mechanism is not completely clear, but the hypothesis of CsA inhibiting P-glycoprotein mediated drug efflux is the most acceptable.

Collision of Lymphoepithelioma-like Carcinoma with Diffuse Large B-cell Lymphoma of the Stomach: A Case Report.

Collision of Epstein-Barr virus (EBV)-associated lymphoepithelioma-like carcinoma (LELC) with non-Hodgkin's lymphoma of the stomach is extremely rare.

Lower Body Lymphedema in Patients with Gynecologic Cancer.

Lower body lymphedema is a chronic condition and a significant cause of morbidity following treatment of gynecologic cancer that strongly impacts patients' quality of life (QoL). Most studies on secondary lymphedema have been performed on the upper limb after breast cancer treatment and much less is known about lower body lymphedema after gynecologic malignancies. This review focuses on secondary lymphedema due to gynecologic cancer treatment, analyzing its incidence in the different types of gynecologic cancer, diagnosis, risk factors, impact on QoL and treatment. A systematic search of Medline has been performed to track the studies evaluating lower body lymphedema after treatment for endometrial, ovarian, cervical and vulvar cancer. Unfortunately, there is no consensus about a uniform evaluation and, as a consequence, the reported incidence is broadly different among the studies. Standardization in lymphedema evaluation is required to better compare the outcome of different types of treatment.

Impact of mass drug administration for elimination of lymphatic filariasis in Nepal.

Lymphatic filariasis (LF) is a neglected tropical disease transmitted by mosquitoes. Nepal has implemented a national effort to eliminate LF by 2020 through mass drug administration (MDA) using diethylcarbamazine (DEC) and albendazole (ALB). We assessed the impact of MDAs on LF in selected districts of Nepal after the recommended six MDA rounds had been completed.

Multidisciplinary approach and long-term follow-up in a series of 640 consecutive patients with sarcoidosis: Cohort study of a 40-year clinical experience at a tertiary referral center in Barcelona, Spain.

Cohort studies of large series of patients with sarcoidosis over a long period of time are scarce. The aim of this study is to report a 40-year clinical experience of a large series of patients at Bellvitge University Hospital, a tertiary university hospital in Barcelona, Spain. Diagnosis of sarcoidosis required histological confirmation except in certain specific situations. All patients underwent a prospective study protocol. Clinical assessment and follow-up of patients were performed by a multidisciplinary team.From 1976 to 2015, 640 patients were diagnosed with sarcoidosis, 438 of them (68.4%) were female (sex ratio F/M 2:1). The mean age at diagnosis was 43.3 ± 13.8 years (range, 14-86 years), and 613 patients (95.8%) were Caucasian. At diagnosis, 584 patients (91.2%) showed intrathoracic involvement at chest radiograph, and most of the patients had normal pulmonary function. Erythema nodosum (39.8%) and specific cutaneous lesions (20.8%) were the most frequent extrapulmonary manifestations, but there was a wide range of organ involvement. A total of 492 patients (76.8%) had positive histology. Follow-up was carried out in 587 patients (91.7%), over a mean of 112.4 ± 98.3 months (range, 6.4-475 months). Corticosteroid treatment was administered in 255 patients (43.4%), and steroid-sparing agents in 49 patients (7.7%). Outcomes were as follows: 111 patients (18.9%) showed active disease at the time of closing this study, 250 (42.6%) presented spontaneous remission, 61 (10.4%) had remission under treatment, and 165 (28.1%) evolved to chronic sarcoidosis; among them, 115 (19.6%) with mild disease and 50 (8.5%) with moderate to severe organ damage. A multivariate analysis showed that at diagnosis, age more than 40 years, the presence of pulmonary involvement on chest radiograph, splenic involvement, and the need of treatment, was associated with chronic sarcoidosis, whereas Löfgren syndrome and mediastinal lymphadenopathy on chest radiograph were indicators of good outcome.Sarcoidosis is a multisystem disease with protean clinical-radiographic manifestations. Although almost half of patients follow a spontaneous resolution or under treatment, a significant number of them may have several degrees of organ damage. This study emphasizes the value of a multidisciplinary approach and long-term follow-up by specialized teams in sarcoidosis.

Correlation between elevated platelet count and immunoglobulin levels in the early convalescent stage of Kawasaki disease.

Kawasaki disease (KD) may be an acute systemic immune-mediated disease which occurs after infection of unknown KD pathogen(s). The aim of this study is to evaluate the changes in platelet count and immunoglobulin (Ig) levels (IgG, IgM, IgA, and IgE) during hospitalization.Forty-three patients with complete KD who received intravenous Ig at 2 g/kg were enrolled in South Korea. The platelet count and Ig levels of the patients were examined twice at presentation and around discharge (mean 6.2 ± 2.4 days apart) and the relationships between platelet level and Ig levels were evaluated.The mean patient age was 31 ± 18 months; 28 patients were male and 15 were female. The values of all parameters measured, with the exception of IgE, were significantly increased at the second examination compared with their values at presentation. These values gradually increased over time after fever onset, over periods ranging from 2 to 16 days. The extent by which platelet levels increased over these 2 time points was correlated with the extents by which IgG (P < .01), IgM (P < .01), and IgA levels (P = .01) increased.Both the platelet count and the Ig (IgG, IgM, and IgA) levels increased with a correlation each other during the early convalescent stage of KD. This finding suggests that all Ig subtypes except IgE and platelets may be involved in the recovery from KD and that the extent of increased parameters may reflect the degree of systemic inflammation in acute KD.

Thrombocytopenia in pregnancy with different diagnoses: Differential clinical features, treatments, and outcomes.

To investigate the clinical features and perinatal treatment of thrombocytopenia induced by different causes during pregnancy.Clinical data from 195 pregnant women with thrombocytopenia attending 2 tertiary hospitals from January 2014 to October 2016 were retrospectively studied. The obtained data were analyzed with SPSS 19.0 software.There were 117 (60.0%), 55 (28.2%), and 23 cases (11.8%) of pregnancy-associated thrombocytopenia (PAT), idiopathic thrombocytopenia (ITP), and hypertensive disorder in pregnancy (PIH), respectively. The percentage of nulliparous women, gestational age at delivery, date of diagnosis of thrombocytopenia, and delivery mode significantly differed between the patients in these 3 groups (P < .05). Patients with PIH had a higher percentage of premature delivery and of lower birth weight infants than patients in the other 2 groups. The 3 groups had similar incidences of postpartum hemorrhage, rates of stillbirth, and neonatal Apgar scores at 5 minutes. PAT and PIH patients had different platelet counts after delivery compared with at diagnosis, whereas the platelet counts of the ITP patients were similar at diagnosis and after delivery. ITP patients in the nontreatment group and the treatment group had significantly different platelet counts (P < .05), and in the treatment group, the maternal platelet count did not differ for treatment with intravenous immunoglobulin (IVIg) versus corticosteroids.The causes of thrombocytopenia in pregnancy are diverse, and the clinical features vary widely. Timely analysis is needed to determine the primary cause of thrombocytopenia, and appropriate therapy should then be selected to effectively improve the prognosis of pregnancies.

Case 244: Systemic Amyloidosis-A Complication of Waldenström Macroglobulinemia.

History A 68-year-old man was admitted to the hospital for work-up because of generalized fatigue, anorexia, chronic diarrhea, and weight loss. Laboratory work-up revealed an erythrocyte sedimentation rate of 58 mm/h (reference range, 3-23 mm/h), a hemoglobin level of 14.1 g/dL (reference range, 13.8-17.5 g/dL), a leukocyte count of 8.1 × 10(9)/L (reference range, [3.4-9.7] × 10(9)/L), a platelet count of 223 × 10(9)/L (reference range, [158-424] × 10(9)/L), an alkaline phosphatase level of 85 U/L (1.42 μkat/L) (normal level, <142 U/L [2.37 μkat/L]), a serum creatinine level of 93 μmol/L (reference range, 79-125 μmol/L), a serum total protein level of 82 g/L (reference range, 66-81 g/L), a serum albumin level of 39.3 g/L (reference range, 40.2-47.6 g/L), an albumin-to-globulin ratio (a test showing relative amounts of major plasma proteins) of 0.92 (reference range, 0.8-2.0), a urine protein level of 15 mg/dL (normal level, <20 mg/dL), a total serum calcium level of 2.46 mmol/L (reference range, 2.14-2.53 mmol/L), and a carcinoembryonic antigen value of 2.69 μg/L (normal value, <3.4 μg/L). Serology findings were negative for celiac disease. Thyroid function was normal, as were 5-hydroxyindoleacetic acid and chromogranin A levels. Initial radiologic examination included chest radiography and plain abdominal erect radiography. Gastrointestinal endoscopy was performed to rule out inflammatory bowel disease or gastrointestinal neoplasm as a cause of chronic diarrhea. Endoscopic mucosal resection of two polyps from the cardia and duodenal bulb was performed during esophagogastroduodenoscopy, but histologic findings at hematoxylin-eosin staining were normal. Colonoscopy revealed diverticulosis involving the entire colon. Serum immunoelectrophoresis showed a monoclonal band, which was confirmed to be immunoglobulin Mλ at immunofixation. After histologic analysis of the bone marrow biopsy specimen, diagnosis of Waldenström macroglobulinemia was established, and computed tomography (CT) of the thorax, abdomen, and pelvis was requested to depict lymphadenopathy and organomegaly. On the basis of CT findings, two more specimens considered highly sensitive for the CT diagnosis were obtained via minimally invasive biopsy, but the results were negative. Magnetic resonance (MR) imaging was performed a year later to control the progression of CT findings.

Coagulopathy and haemorrhagic progression in traumatic brain injury: advances in mechanisms, diagnosis, and management.

Normal haemostasis depends on an intricate balance between mechanisms of bleeding and mechanisms of thrombosis, and this balance can be altered after traumatic brain injury (TBI). Impaired haemostasis could exacerbate the primary insult with risk of initiation or aggravation of bleeding; anticoagulant use at the time of injury can also contribute to bleeding risk after TBI. Many patients with TBI have abnormalities on conventional coagulation tests at admission to the emergency department, and the presence of coagulopathy is associated with increased morbidity and mortality. Further blood testing often reveals a range of changes affecting platelet numbers and function, procoagulant or anticoagulant factors, fibrinolysis, and interactions between the coagulation system and the vascular endothelium, brain tissue, inflammatory mechanisms, and blood flow dynamics. However, the degree to which these coagulation abnormalities affect TBI outcomes and whether they are modifiable risk factors are not known. Although the main challenge for management is to address the risk of hypocoagulopathy with prolonged bleeding and progression of haemorrhagic lesions, the risk of hypercoagulopathy with an increased prothrombotic tendency also warrants consideration.

Late Cardiac Toxicity After Mediastinal Radiation Therapy for Hodgkin Lymphoma: Contributions of Coronary Artery and Whole Heart Dose-Volume Variables to Risk Prediction.

Mediastinal radiation therapy (RT) for Hodgkin lymphoma (HL) is associated with late cardiotoxicity, but there are limited data to indicate which dosimetric parameters are most valuable for predicting this risk. This study investigated which whole heart dosimetric measurements provide the most information regarding late cardiotoxicity, and whether coronary artery dosimetry was more predictive of this outcome than whole heart dosimetry.

Lymphatic filariasis patient identification in a large urban area of Tanzania: An application of a community-led mHealth system.

Lymphatic filariasis (LF) is best known for the disabling and disfiguring clinical conditions that infected patients can develop; providing care for these individuals is a major goal of the Global Programme to Eliminate LF. Methods of locating these patients, knowing their true number and thus providing care for them, remains a challenge for national medical systems, particularly when the endemic zone is a large urban area.

An infrequent cause of iron-deficiency anemia: Ménétrier disease.

Ménétrier disease is a rare condition of an unknown origin, with a wide spectrum of clinical signs and symptoms at presentation. Diagnosis is made through the combination of clinical, analytical, endoscopic and histological data. Surgery is the classical treatment. However, new medical approaches have emerged.
