Surgical management of lung cancer in Western Australia in 1996 and its outcomes

Background: All cases of lung cancer diagnosed in Western Australia in 1996 in which surgery was the primary treatment, were reviewed. Reported herein are the characteristics of the patients, the treatment outcomes and a comparison of the management undertaken with that recommended by international guidelines. Methods: All patients with a new diagnosis of lung cancer in Western Australia in the calendar year of 1996 were identified using two different population-based registration systems: the Western Australian (WA) Cancer Registry and the WA Hospital Morbidity Data System. A structured questionnaire on the diagnosis and management was completed for each case. Date of death was determined through the WA Cancer Registry. Results: Six hundred and sixty-eight patients with lung cancer were identified; 132 (20%) were treated with surgery. Lobectomy was the most frequently performed procedure (71%), followed by pneumonectomy (19%). Major complications affected 23% of patients. Postoperative mortality was 6% (3% lobectomy, 12% pneumonectomy). At 5 years the absolute survival was as follows for stage I, II, IIIA, IIIB, respectively: 51%, 45%, 12%, 5%. Conclusions: Investigations and choice of surgery in WA in 1996 reflect current international guidelines. The survival of patients with resectable lung cancer remains unsatisfactory.

Francoist Primary education: the schoolbook as an instrument of child indoctrination

The Francoist rule, mainly in its first decades, exerted a strong control upon education, which was left in the hands of the Catholic nationalist. Innumerous children`s schoolbooks were published driven by strong patriotic and religious bias. The authors aimed to shape the children`s minds based on the premises that supported the regimen: authority, hierarchy, order, abeyance, fear and devotion to God and the leader Francisco Franco. This paper analyzes the content of the elementary education books and shows how they were important instruments of child indoctrination marked by intolerance. The content and the images of the books contributed to construct an excluding national identity based on a heightened Catholic patriotism, stimulated heroism, martyrdom, child sacrifice, and hatred for the enemies of the religion and of ""mother Spain"".

Adoptive transfer of gene-engineered CD4+ helper T cells induces potent primary and secondary tumor rejection

Because CD4(+) T cells play a key role in aiding cellular immune responses, we wanted to assess whether increasing numbers of gene-engineered antigen-restricted CD4(+) T cells could enhance an antitumor response mediated by similarly gene-engineered CD8(+) T cells. In this study, we have used retroviral transduction to generate erbB2-reactive mouse T-cell populations composed of various proportions of CD4(+) and CD8(+) cells and then determined the antitumor reactivity of these mixtures. Gene-modified CD4(+) and CD8(+) T cells were shown to specifically secrete Tc1 (T cytotoxic-1) or Tc2 cytokines, proliferate, and lyse erbB2(+) tumor targets following antigen ligation in vitro. In adoptive transfer experiments using severe combined immunodeficient (scid) mice, we demonstrated that injection of equivalent numbers of antigen-specific engineered CD8(+) and CD4(+) T cells led to significant improvement in survival of mice bearing established lung metastases compared with transfer of unfractionated (largely CD8(+)) engineered T cells. Transferred CD4(+) T cells had to be antigen-specific (not just activated) and secrete interferon gamma (IFN-gamma) to potentiate the antitumor effect. Importantly, antitumor responses in these mice correlated with localization and persistence of gene-engineered T cells at the tumor site. Strikingly, mice that survived primary tumor challenge could reject a subsequent re-challenge. Overall, this study has highlighted the therapeutic potential of using combined transfer of antigen-specific gene-modified CD8(+) and CD4(+) T cells to significantly enhance T-cell adoptive transfer strategies for cancer therapy.

Primary Antiphospholipid Syndrome and Thyroid Involvement

Background: Data on thyroid involvement in primary antiphospholipid syndrome are scarce and inconclusive. Objectives: The aim of this study was to evaluate the frequency of thyroid dysfunction and antibodies in patients with primary antiphospholipid syndrome ( PAPS) and the association of these alterations with clinical and immunologic features. Methods: The study group included 50 PAPS patients (44 females) with a mean age of 39.7 +/- 11.5 years and mean disease duration of 77.3 +/- 63.5 months. Clinical data related to thyroid dysfunction and PAPS were obtained by chart review, patient interview, and clinical examination. Serum levels of TSH, free T4, antithyroglobulin antibody (TgAb), antithyroperoxidase antibody (TPOAb), thyroid receptor antibody (TRAb), and antiphospholipid autoantibodies were analyzed by standard techniques. Results: We found no hyperthyroidism among patients and found 22% (11 patients) with hypothyroidism in this sample. There were no differences between the latter patients and the euthyroid group about demographic findings, disease duration, thrombotic or obstetric events, and frequency of antiphospholipid antibodies as well as prevalence of thyroid auto antibodies. The prevalence of thyroid autoantibodies found was 6 patients (12%) with TgAb, 5 with TPOAb (10%), and 2 patients (4%) with both TgAb and TPOAb, comprising 18% of positivity of at least one of the auto antibodies. Conclusion: Hypothyroidism is present among 22% of PAPS patients and thyroid autoantibodies in 18% of them. These findings suggest a common pathophysiologic mechanism between antiphospholipid syndrome and autoimmune thyroid diseases.

Prostatic Artery Embolization as a Primary Treatment for Benign Prostatic Hyperplasia: Preliminary Results in Two Patients

Symptomatic benign prostatic hyperplasia (BPH) typically occurs in the sixth and seventh decades, and the most frequent obstructive urinary symptoms are hesitancy, decreased urinary stream, sensation of incomplete emptying, nocturia, frequency, and urgency. Various medications, specifically 5-alpha-reductase inhibitors and selective alpha-blockers, can decrease the severity of the symptoms secondary to BPH, but prostatectomy is still considered to be the traditional method of management. We report the preliminary results for two patients with acute urinary retention due to BPH, successfully treated by prostate artery embolization (PAE). The patients were investigated using the International Prostate Symptom Score, by digital rectal examination, urodynamic testing, prostate biopsy, transrectal ultrasound (US), and magnetic resonance imaging (MRI). Uroflowmetry and postvoid residual urine volume complemented the investigation at 30, 90, and 180 days after PAE. The procedure was performed under local anesthesia; embolization of the prostate arteries was performed with a microcatheter and 300- to 500-mu m microspheres using complete stasis as the end point. One patient was subjected to bilateral PAE and the other to unilateral PAE; they urinated spontaneously after removal of the urethral catheter, 15 and 10 days after the procedure, respectively. At 6-month follow-up, US and MRI revealed a prostate reduction of 39.7% and 47.8%, respectively, for the bilateral PAE and 25.5 and 27.8%, respectively, for the patient submitted to unilateral PAE. The early results, at 6-month follow-up, for the two patients with BPH show a promising potential alternative for treatment with PAE.

MR Imaging Findings of Iron Overload

Hemochromatosis can be classified as (a) primary, when it originates from a genetic disturbance that promotes the increase of iron absorption, or (b) secondary, when it relates to chronic diseases or to multiple transfusions. The distribution of iron accumulation differs between these two forms; therefore, they can be distinguished by using imaging methods in the majority of cases. Magnetic resonance (MR) imaging is the most sensitive and specific imaging modality in the diagnosis of hemochromatosis. The susceptibility effect caused by the accumulation of iron leads to signal loss in the affected tissues, particularly with the T2*-weighted sequences, which makes the diagnosis of iron overload possible. By using MR imaging techniques, it is possible to estimate the hepatic iron concentration in a noninvasive way, thereby avoiding repeated biopsies. Hemochromatosis can lead to complications, such as a higher frequency of neoplasia, particularly the development of hepatocellular carcinoma. Other neoplasms, such as colorectal tumors, are also associated. Complications related to the treatment of chronic anemia include the appearance of peliosis hepatis and tumors, which can regress after the suspension of treatment with drugs. Knowledge of the disease and of the patterns of iron deposition in patients with iron overload enables not only diagnosis, but also treatment, follow-up, and the detection of possible complications by using imaging methods.

Primary antiphospholipid syndrome with thrombotic thrombocytopenic purpura: a very unusual association

This report considers the rare situation in which primary antiphospholipid syndrome (PAPS) is linked with thrombotic thrombocytopenic purpura (TTP). It describes the case of a young lady with PAPS, characterized by recurring cerebro-vascular abnormalities and marked livedo reticularis, combined with circulating anticardiolipin and lupus anticoagulant antibodies. On follow-up, while on oral anticoagulation, she developed severe thrombocytopenia associated with hematuria, microangiophatic anaemia and neurological manifestations consistent with a diagnosis of TTP. The patient was treated with pulses of methylprednisolone and plasmapheresis with plasma exchange. The result was a favourable outcome. To our knowledge, this is the seventh report on this rare association in the English-language literature of this field. Lupus (2009) 18, 841-844.

Fibromyalgia in primary antiphospholipid (Hughes) syndrome

Fibromyalgia (FM) is a syndrome that can be associated with several rheumatic diseases. However, no study has evaluated its frequency in patients with primary antiphospholipid syndrome (PAPS). The objective of this study was to analyze the frequency of FM in PAPS patients compared with healthy controls, to determine the possible associations between FM and PAPS features, and also to evaluate quality of life and depression in these patients. This case-control study included 30 PAPS patients (by the Sapporo criteria) and 40 healthy subjects. Demographic and clinical data, drug use, and antiphospholipid antibodies were analyzed. FM was diagnosed based on international criteria (ACR). Questionnaires on quality of life, including the Short Form 36 Health Survey (SF-36), Beck Depression Inventory (BDI), Fibromyalgia Impact Questionnaire (FIQ), and Visual Analog Scale (VAS), were also applied. PAPS patients and controls were similar in mean age as well as in distributions of gender and Caucasian race. Mean disease duration was 5.4 +/- 4.2 years. A diagnosis of fibromyalgia was made in five (16.7%) PAPS patients and no controls (p = 0.012). PAPS patients had more diffuse pain (53% vs. 0%, respectively, p<0.0001), >= 11 tender points (23% vs. 5%, respectively, p = 0.032), and a greater total number (175 vs. 57, respectively, p<0.0001) as well as median number of tender points per patient than controls (5 [0-18] vs. 0 [0-11], respectively, p<0.0001). PAPS patients had lower values in all dimensions of the SF-36, as well as higher FIQ scores, higher BDI scores, more depression diagnoses according to BDI results, and increased VAS in comparison with controls. Analysis of PAPS patients with FM compared with those subjects without FM revealed no significant differences regarding demographic features or thrombotic or clinical events; however, PAPS patients who also had FM had lower values in SF-36 dimensions as well as higher FIQ (82.6 +/- 9.6 vs. 33.6 +/- 29.8, respectively, p<0.0001) and VAS scores (6.6 +/- 2.97 vs. 3.25 +/- 3.11, respectively, p = 0.03). BDI scores, in contrast, were similar in both groups. In conclusion, one-fifth of PAPS patients had fibromyalgia and a low quality of life when compared with healthy subjects.

Influence of gender on the clinical and laboratory spectra of patients with primary antiphospholipid syndrome

The objectives of this cross-sectional study were to evaluate the differences between males and females in the clinical and biochemical manifestations of primary antiphospholipid antibody syndrome (PAPS). The method involved 49 patients (38 premenopausal females and 11 males) diagnosed with PAPS (according to the Sapporo criteria) and their demographic data, clinical data, medications used and antiphospholipid antibodies were analyzed. The results of this study are as follows. Both the groups of patients were statistically similar regarding age, race, weight and body mass index. However, males were significantly taller than females (172 +/- A 8.9 vs. 159.2 +/- A 6.2 cm, p < 0.0001). The duration of disease was similar for females and males. The prevalence of pulmonary thromboembolism was higher in females than in males (34.2 vs. 0.0%, p = 0.024). Regarding other PAPS manifestations (arterial events, venous events, deep venous thrombosis, thrombocytopenia, acute myocardial infarction, angina, cerebrovascular accidents and Sneddon syndrome), comorbidities (arterial hypertension and dyslipidemia), lifestyle (physical activity, previous smoking and current smoking) and the use of medications (current and previous use of corticosteroids, as well as the use of statins or chloroquine), both groups were statistically similar (p > 0.05). More females than males tested positive for IgM anticardiolipin antibodies (76.3 vs. 36.4%, p = 0.025) or for at least one of the antiphospholipid antibodies tested (either IgM anticardiolipin or IgG anticardiolipin 84.2 vs. 45.5%, p = 0.016). However, both groups were similar regarding the frequency of positivity for lupus anticoagulant and isolated IgG anticardiolipin, as well as regarding mean levels of IgG and IgM anticardiolipin (p > 0.05). We concluded that, among PAPS patients, the frequency of pulmonary thromboembolism and of positivity for IgM anticardiolipin is higher in females than in males. Our findings show that there are gender differences in PAPS, differences that might be related to alterations in sex hormones.

Primary antiphospholipid syndrome with and without Sneddon`s syndrome

The main objective of this study was to compare clinical and laboratory data obtained from patients with primary antiphospholipid syndrome (PAPS) with and without Sneddon`s syndrome (SS). A transverse study with 54 (85.2% female) PAPS patients (Sapporo criteria) was performed. Demographic, drug use, and antiphospholipid antibodies data were evaluated, as well as clinical and laboratory findings of SS. Patients were subdivided into one of two groups: PAPS with SS and PAPS without SS. Both groups were similar with respect to age (p = 0.05), gender (p = 0.34), race (p = 0.31), weight (p = 0.93), height (p = 0.27), and body mass index (p = 0.75); however, the SS group exhibited higher disease duration (96.0 +/- A 54.9 vs. 55.2 +/- A 52.0 months, p = 0.01). By definition, all PAPS with SS patients suffer from stroke, an arterial event; the frequency of stroke events (28.5 vs. 7.5%, p = 0.04), as well as of limb ischemia (100 vs. 30.0%, p < 0.0001) was higher in this group than in the PAPS without SS group. On the other hand, patients in the PAPS without SS group had more venous events, such as deep venous thrombosis, than those in the PAPS with SS group (80.0 vs. 50.0%, p = 0.03). In conclusion, an understanding of the relationship between APS and SS is important in order to identify a subgroup for which more rigorous accompaniment and therapy may be necessary.

Pathological gambling and primary antiphospholipid (Hughes) syndrome: a unique neuropsychiatric association

Neuropsychiatric conditions are common in patients with primary antiphospholipid syndrome (APS) with or without vascular thrombosis of the central nervous system. There are frequent descriptions of memory alterations, cognition and mood disorders, such as depression, anxiety, and even conditions of mania and psychosis preceding the diagnosis of primary APS. However, this study is the first to present primary or secondary APS associated with habit or impulse control disorders. The authors describe the case of a 53-year-old male patient who had been a pathological gambler since adulthood and who has had APS for more than 20 years. We describe the case and review its characteristics, criteria for diagnosis and treatment offered for patients with this specific subtype of impulse disorder. Lupus (2011) 20, 1086-1089.

Prostate cryoablation: Prospective analysis comparing high- and low-risk prostate cancer outcomes

Aim: To evaluate percutaneous cryotherapy as a primary treatment option for prostate cancer, comparing different risk groups. Patients and Methods: Forty-seven prostate cryoablation procedures were performed on 44 patients. Patients median age was 70.9, and average pretreatment PSA of 13.8 ng/dl. Patients were divided into low-risk (13 patients), high-risk (24 patients) and radiation failure patients (7 patients). The follow-up period ranged from 18 to 60 months (median 41 months). Results: In the low-risk group, we found after 12 and 24 months of follow-up, 92 and 86% of patients free of PSA relapse (PSA < 1 ng/ml), respectively. In the high-risk group, the PSA failure was 39 and 52.9%. For the radiation failure group, 86 and 71.4% of patients had PSA below 1 ng/dl. At 48 months of follow-up, 80% of the low-risk patients, 42.8% of the high-risk group and 71.4% of the radiation failure group were free of PSA relapse. The complication rates were low, with 13% of urinary incontinence and no cases of rectal injury. Conclusion: Prostate cryoablation is a viable and promising minimally invasive alternative for localized or locally advanced prostate cancer patients. Copyright (c) 2008 S. Karger AG, Basel.

Evaluation of Primary Cleft Nose Repair: Severity of the Cleft Versus Final Position of the Nose

Background: Since 1957, when the concept of rotation-advancement repair was introduced by Millard, this technique has become the procedure of choice for unilateral cleft lip worldwide. More recently, modifications described by Noordhoof, Mohler, Skoog, and McComb started being jointly performed so that better results could be obtained. In this study, the nasal position was evaluated and related to the size of the cleft. The primary unilateral cleft lip repair was performed through a modified technique. Methods: Forty-five patients with unilateral cleft lip underwent primary surgical repair through this technique. To analyze aesthetic results, a severity classification of deformities and a scoring system for evaluation of the results were established based on nasal alar lateralization, dome position, alignment of bone segments, and deviation of the columella. Results: By means of the established system, 26.6% of mild forms, 13.4% of moderate forms, and 60% of severe forms were observed. Among aesthetic results, 17.8% were found to be good, and 82.2% were considered excellent. Among aspects considered negative, late deformity of the lower lateral cartilage prevailed. Conclusions: Through the presented evaluation, the authors observed that there was no relation between severity of the cleft and final position of the nose. Among the 27 patients considered to have had severe forms of cleft deformity, 22 were classified as excellent results (81.5%). To obtain better results along time, technical refinements and the critical analysis of results must be performed on a routinely basis.
