Epidemiology of arterial hypertension in patients scheduled for elective hip replacement

Background: Assessment of blood pressure values and early diagnosis of hypertension are especially important in high-risk group, including patients in preoperative and postoperative period. The aim of the current study was the assessment of blood pressure values and prevalence of hypertension in patients undergoing elective hip replacement surgery — an orthopedic procedure associated with one of the highest cardiovascular complication rate. Material and methods: Two hundred and eighty-four consecutive patients admitted for elective hip replacement surgery were screened for arterial hypertension. All patients had their medical records reviewed for prior diagnosis and had their blood pressure measured on admission by a qualified physician prior to the procedure, according to the current guidelines. Results: The mean age of the study population was 62.2 ± 13.9 years and 42.7% of the patients were male. The body mass index (BMI) in the study population was 27.0 ± 4.2 kg/m2. Fifty-eight point two percent of patients were diagnosed with arterial hypertension previously. Mean blood pressure values on admission for systolic blood pressure (SBP) and diastolic blood pressure (DBP) were 134.5 ± 20.4 and 78.6 ± 13.1 mm Hg, respectively. In 43.2% of patients, the on admission blood pressure values exceeded the threshold of ≥ 140 and/or 90 mm Hg. Arterial hypertension was diagnosed de novo in 33 (15.0%) patients. Patients with the disease were older (67.5 ± 12.3 vs. 54.4 ± 13.9 years; p < 0.0001), and had higher BMI (27.6 ± 4.3 vs. 26.2 ± 3.8 kg/m2; p = 0.05) than patients without the diagnosed disease. Diabetes mellitus was more often found in hypertensive patients (13.3% vs. 3.3%; p = 0.02), they also more often had history of myocardial infarction (p = 0.02), stable coronary artery disease (p = 0.001) and heart failure (p = 0.006) compared to patients without the diagnosis. Conclusions: The majority of patients scheduled for elective hip replacement surgery is diagnosed with arterial hypertension. The disease is also diagnosed de novo in 15% of these patients. Screening for arterial hypertension is important in this group of patients and can potentially reduce the complication rates of the hip replacement surgery.Background: Assessment of blood pressure values and early diagnosis of hypertension are especially important in high-risk group, including patients in preoperative and postoperative period.

Childhood rhabdomyosarcoma metastatic to bone marrow presenting with disseminated intravascular coagulation and acute tumour lysis syndrome: review of the literature apropos of two cases

The paper presents diagnostic and therapeutic difficulties in two adolescents with widespread rhabdomyosarcoma (RMS) presenting with severe haemorrhages resulting from disseminated intravascular coagulation (DIC) and with laboratory features of acute tumour lysis syndrome (ATLS). Other published cases of childhood RMS with DIC at admission have been listed and reviewed. It has been concluded that the clinical picture of a widespread RMS in children may resemble acute hematologic malignancy and pose a big diagnostic problem. That is why the presence of small blue round cells morphologically similar to lymphoblasts and/or myeloblasts in bone marrow (BM), lacking hematopoietic makers, should prompt the pathologist to consider possible diagnosis of RMS. Inclusion of desmin, MyoD1 and myogenin Myf4 to the immunohistochemical panel is obligatory in such cases. When the representative histopathological tumour specimens are difficult to obtain, the flow cytometric immunophenotyping of BM metastases could help the standard morphological/immunohistological diagnostic procedures and advance the diagnosis. Recently, the flow cytometric CD45− CD56+ immunophenotype together with Myf4 transcript has been assigned to RMS cells infiltrating BM. In children with disseminated RMS complicated with DIC rapid polychemotherapy aimed at diminishing the malignancy-triggered procoagulant activity should be initiated. However, in cases with concomitant ATLS the initial doses of chemotherapy should be reduced and the metabolic disorders and renal function monitored. The prognosis in children with RMS metastatic to BM with signs of DIC or ATLS at admission depends on the response to chemotherapy, however generally it is highly disappointing

Papillary Thyroid Carcinoma in a Boy with Familial Tuberous Sclerosis Complex Attributable to a TSC2 Deletion—A Case Report

Tuberous sclerosis complex (TSC), a phacomatosis, is a rare genetic disease (autosomal dominant; incidence: 1 in 6,800–17,300) associated with mutations in the TSC1 and TSC2 genes, 70% of which are sporadic. The disease causes benign tumours in the brain, kidneys, heart, lungs, skin, and eyes; thyroid lesions are extremely rare. A 13-year-old euthyroid boy with a hereditary form of TSC (del 4730G in TSC2, also seen in 2 sisters and the father) was admitted to hospital with a thyroid nodule. Physical examination revealed a nodular left lobe with increased consistency. Thyroid ultrasonography revealed a heterogeneous left lobe, predominantly hypoechoic with multiple microcalcifications and the presence of suspicious cervical lymph nodes on the left side. A macrocalcification was observed on the right lobe. Fine-needle biopsy results showed a few groups of cells with discrete atypical characteristics, including abundant cytoplasm, nuclei with conspicuous nucleoli, intra-nuclear inclusions, and nuclear grooves. The patient underwent total thyroidectomy with lymphadenectomy. Histopathology examination confirmed papillary thyroid carcinoma. The coincidence of endocrine neoplasia including thyroid cancer and TSC is rare, and TSC with papillary thyroid carcinoma has never been described in a child. Studies of mutations in the tumour suppressor genes TSC1, TSC2, and STK11, activating the mtor (mammalian target of rapamycin) pathway, might support their role in the pathogenesis of thyroid cancer

Diagnosis and immunophenotype of 188 pediatric lymphoblastic lymphomas treated within a randomized prospective trial: experiences and preliminary recommendations from the European childhood lymphoma pathology panel

The majority of lymphoblastic (precursor cell) neoplasms presents as leukemias. Consequently, the guidelines for lineage determination and subtyping of precursor cell neoplasms were primarily established for flow cytometry methods. Large-scale studies of nonleukemic lymphoblastic lymphomas are lacking so far. We analyzed a large series of pediatric patients with lymphoblastic lymphoma treated within a prospective randomized trial (the Euro-LB 02 study). Among 193 lymphomas, in which a detailed immunohistochemical analysis was carried out, there were several unusual and diagnostically challenging morphologic and immunophenotypical variants. These included 11 lymphomas with mixed phenotypes expressing markers of at least 2 hematopoietic lineages, 7 terminal deoxynucleotide transferase-negative lymphoblastic lymphomas, and 3 undifferentiated hematopoietic neoplasms that could not be assigned to any lineage with certainty. Our data indicate that World Health Organization guidelines for lineage determination and subtyping of precursor cell leukemia need to be adapted before they can be applied to immunohistochemical diagnosis of lymphoma. Using the experience from this cohort we suggest a resource-saving diagnostic staining panel for the immunohistochemical analysis of precursor cell neoplasms in formalin-fixed paraffin-embedded tissue

Reproducibility of the Oxford Classification of IgA nephropathy, impact of biopsy scoring on treatment allocation and clinical relevance of disagreements: evidence from the VALIGA study cohort

Objective & Methods: The VALIGA study investigated the utility of the Oxford Classification of IgA nephropathy (IgAN) in 1147 patients from 13 European countries. Biopsies were scored by local pathologists followed by central review in Oxford. We had two distinct objectives: to assess how closely pathology findings were associated with the decision to give corticosteroid/immunosuppressive treatments (CS/IS), and to determine the impact of differences in MEST-C scoring between central and local pathologists on the clinical value of the Oxford Classification. We tested for each lesion the associations between the type of agreement (local and central pathologists scoring absent, local present-central absent, local absent-central present, both scoring present) with the initial clinical assessment, as well as long-term outcomes in those patients who did not receive CS/IS. Results: All glomerular lesions (M, E, C and S) assessed by local pathologists were independently associated with the decision to administer CS/IS therapy whilst the severity of tubulointerstitial lesions was not. Reproducibility between local and central pathologists was moderate for S (segmental sclerosis) and T (tubular atrophy/interstitial fibrosis), and poor for M (mesangial hypercellularity), E (endocapillary hypercellularity), and C (crescents). Local pathologists found statistically more of each lesion, except for the S lesion, which was more frequent with central review. Disagreements were more likely to occur when the proportion of glomeruli affected was low. The M lesion, assessed by central pathologists, correlated better with the severity of the disease at presentation and discriminated better with outcomes. By contrast, the E lesion, evaluated by local pathologists, correlated better with the clinical presentation and outcomes compared to central review. Both C and S lesions, when discordant between local and central pathologists, had a clinical phenotype intermediate to double absent lesions (milder disease) and double present (more severe). Conclusion: We conclude that differences in the scoring of MEST-C criteria between local pathologists and central reviewer have a significant impact on the prognostic value of the Oxford Classification. Since the decision to offer immunosuppressive therapy in this cohort was intimately associated with the MEST-C score, this study indicates a need for a more detailed guidance for pathologists in the scoring of IgAN biopsies
