Late hemodynamic changes in percutaneous mitral valvuloplasty

Percutaneous mitral valvuloplasty (PMV) was performed in 57 patients with mitral stenosis. Twenty-three women and 34 men (mean age 28 +/- 10 mean +/- SD) were included in the study. A single-balloon (trefoil or bifoil) technique was used in 49 patients and a double-balloon (trefoil + monofoil) technique in eight. After a 3-month follow-up period, right- and left-sided cardiac catheterization was repeated. In the single-balloon group there was improvement in the mitral valve gradient (16.10 +/- 5.99 to 4.41 +/- 2.03 mm Hg), mean left atrial pressure (22.65 +/- 6.13 to 9.76 +/- 3.01 mm Hg), and mitral valve area (0.89 +/- 0.22 to 1.95 +/- 0.46 cm2/m2). Mean pulmonary artery pressure and mean pulmonary wedge pressure decreased to 19.33 +/- 4.19 mm Hg and 10.73 +/- 2.60 mm Hg from 32.94 +/- 7.90 mm Hg and 21.49 +/- 5.98 mm Hg. Cardiac output increased to 6.86 +/- 0.56 L/min from 5.57 +/- 0.66. All improvements were statistically significant (p less than 0.001). In the double-balloon study group, mitral valve gradient (23.75 +/- 2.77 to 4.50 +/- 1.94 mm Hg), mean left atrial pressure (31.63 +/- 3.57 to 9.50 +/- 1.94 mm Hg), mean pulmonary artery pressure (44.00 +/- 6.36 to 18.88 +/- 7.10), and mean pulmonary wedge pressure (29.25 +/- 3.73 to 10.25 +/- 1.85 mm Hg) all improved significantly (p less than 0.001). Mitral valve area and cardiac output increased from 0.89 +/- 0.15 to 2.44 +/- 0.44 cm2/m2 (p less than 0.001) and from 5.46 +/- 0.76 to 7.15 +/- 0.52 L/min (p less than 0.002), respectively.(ABSTRACT TRUNCATED AT 250 WORDS)     

Multiple pulmonary arterial aneurysms in Behçet's disease: clinical and radiologic remission after cyclophosphamide and corticosteroid therapy

Beh?et's disease (BD) with pulmonary arterial aneurysm is rare and often associated with a poor prognosis. But there is also a chance that the aneurysm may completely resolve with medical therapy. A 39-year-old man presented with fever, malaise, bilateral chest pain, recurrent oral ulcers, and hemoptysis. The chest radiograph showed a round opacity in the right hilum. Computed tomography and magnetic resonance angiography (MRA) further revealed multiple, bilateral pulmonary arterial aneurysms consistent with the diagnosis of BD. The patient was started on a course of cyclophosphamide and corticosteroid therapy that resulted in cessation of his symptoms and complete resolution of radiologic findings. The chest radiograph and MRA reverted to normal on long-term follow-up. He is still alive and symptom-free 20 months after diagnosis.     

Immunoglobulin D lambda multiple myeloma and amyloidosis with predominant soft tissue involvement.

Multiple myeloma (MM) is associated with amyloidosis in approximately 15% of the patients. The most frequent presenting signs of such an association are nephrotic syndrome, cardiomyopathy and peripheral neuropathy. Amyloid arthropathy is not a frequent feature. We report a patient with immunoglobulin D (IgD) lambda type MM with presenting symptoms related to mucocutaneous amyloidosis and also amyloid arthropathy. He had no clinical and laboratory involvement due to nephrotic syndrome or cardiomyopathy. IgD myeloma is a rare form of MM and therefore much of the information about the disease is derived from case reports describing patients with associated symptoms. Our case also shows an unusual organ distribution of amyloid.     

The Diagnostic Accuracy of Ultrasonography for the Diagnosis of Rib Fractures in Patients Presenting to Emergency Department With Blunt Chest Trauma

BackgroundRib fractures are the most common complications of blunt chest trauma (BCT). Computed tomography (CT) is the modality of choice for BCT, but with several disadvantages. Ultrasonography (US) is an inexpensive, readily available, and relatively harmless imaging alternative. However, a direct comparison of the sonographic evaluation of the rib as a whole with CT as a reference has not been performed to date.ObjectiveThis study aimed to compare the diagnostic accuracy of US with CT for the detection of rib fractures in patients who presented to emergency department (ED) with BCT.MethodsWe included a convenience sample of adult patients who presented to the ED with thoracic pain after BCT in the last 24 h in this prospective, observational, diagnostic accuracy study. The diagnostic utility of US performed by an emergency physician was compared with thorax CT.ResultsThe final study population included 145 patients. The diagnostic accuracy of US was 80% with a sensitivity of 91.2% and specificity of 72.7% for the detection of any rib fracture (positive likelihood ratio 3.4 and negative likelihood ratio 0.12). If we considered each rib separately, the sensitivity of US decreased to 76.7% and specificity increased to 82.7% (81.3% accuracy).ConclusionsA negative US of the site of the highest tenderness and neighboring ribs in a patient with BCT who presented to the ED with lateralizing pain decreases the possibility of a rib fracture significantly. However, a positive US performs poorly to specify the exact location and number of the fractured ribs.

The combination of cytological smears and cell blocks on endobronchial ultrasound-guided transbronchial needle aspirates allows a higher diagnostic yield

We compared the diagnostic performances of conventional smears and cell block preparations of tissue samples obtained with endobronchial ultrasound-guided transbronchial needle aspiration. We retrospectively analysed 451 patients (926 lymph nodes) who had undergone endobronchial ultrasound and for whom both smears and cell blocks were available and compared the diagnostic performances of these techniques when used alone and combined. Cell block preparations showed higher diagnostic performance over smears, but the combination was superior to either alone. The combination of smear and cell block techniques achieved a sensitivity, specificity and positive and negative predictive values of 92.5, 100, 100, 97.7 and 99.4, 95.0, 98.6, and 97.9 % for malignant and benign diseases, respectively. We recommend cell block preparations during endobronchial ultrasound-guided transbronchial needle aspiration.

The burden attributable to headache disorders in children and adolescents in Lithuania: estimates from a national schools-based study

BackgroundWe recently showed headache to be common in children (aged 7–11 years) and adolescents (aged 12–17) in Lithuania. Here we provide evidence from the same study of the headache-attributable burden.MethodsFollowing the generic protocol for Lifting The Burden’s global schools-based study, this cross-sectional survey administered self-completed structured questionnaires to pupils within classes in 24 nationally representative schools selected from seven regions of the country. Headache diagnostic questions were based on ICHD-3 beta criteria but for the inclusion of undifferentiated headache (UdH; defined as mild headache with usual duration < 1 h). Burden enquiry was conducted in multiple domains.ResultsQuestionnaires were completed by 2505 pupils (1382 children, 1123 adolescents; participating proportion 67.4%), of whom 1858 reported headache in the preceding year, with mean frequency (±SD) of 3.7 ± 4.5 days/4 weeks and mean duration of 1.6 ± 1.9 h. Mean proportion of time in ictal state, estimated from these, was 0.9% (migraine 1.5%, probable medication-overuse headache [pMOH] 10.9%). Mean intensity on a scale of 1–3 was 1.6 ± 0.6 (mild-to-moderate). Symptomatic medication was consumed on 1.5 ± 2.8 days/4 weeks. Lost school time was 0.5 ± 1.5 days/4 weeks (migraine 0.7 ± 1.5, pMOH 5.0 ± 7.8) based on recall, but about 50% higher for migraine according to actual absences recorded in association with reported headache on the preceding day. More days were reported with limited activity (overall 1.2 ± 2.4, migraine 1.5 ± 2.2, pMOH 8.4 ± 8.5) than lost from school. One in 30 parents (3.3%) missed work at least once in 4 weeks because of their son’s or daughter’s headache. Emotional impact and quality-of-life scores generally reflected other measures of burden, with pMOH causing greatest detriments, followed by migraine and tension-type headache, and UdH least. Burdens were greater in adolescents than children as UdH differentiated into adult headache types.ConclusionsHeadache in children and adolescents in Lithuania is mostly associated with modest symptom burden. However, the consequential burdens, in particular lost school days, are far from negligible for migraine (which is prevalent) and very heavy for pMOH (which, while uncommon in children, becomes four-fold more prevalent in adolescents). These findings are of importance to both health and educational policies in Lithuania.     

Unusual Malignant Solid Neoplasms of the Kidney: Cross-Sectional Imaging Findings

Malignant kidney neoplasms are the most frequently encountered solid kidney masses. Although renal cell carcinoma is the major renal malignancy, other solid malignant renal masses should be considered in the differential diagnosis of solid renal masses that do not contain a macroscopic fatty component. In this pictorial essay, we present the imaging findings of a primitive neuroectodermal tumor, primary liposarcoma of the kidney, primary neuroendocrine tumor, leiomyosarcoma, synovial sarcoma, malignant fibrous histiocytoma, sclerosing fibrosarcoma and renal metastasis of osteosarcoma.
