A prospective study of Toxoplasma-positive pregnant women in southern Brazil: a health alert

We evaluated anti-Toxoplasma gondii IgM-reactive pregnant women seen at a high-risk pregnancy outpatient clinic. From March 2005 to January 2008 in Paraná, Brazil, pregnant women seen by the Brazilian Public Health System, in any gestational period, who were anti-T. gondii IgM-positive, were followed. Clinical symptoms were noted, and tests performed including IgA, IgG avidity, ultrasonogram, and amniocentesis (PCR/inoculation in mice). Of 75 patients, 8 showed low, 3 intermediate and 31 high IgG avidity. Of those who underwent the avidity test, 31 (70.5%) were in the second trimester of pregnancy. Thirty-two (42.7%) pregnant women received specific treatment. Six received triple combination treatment; in three, tachyzoites were isolated, although only one was PCR-positive, showing changes in the cerebral sonogram, borderline IgA, and the Sabin tetrad. One fetus died, and one non-reactive IgM pregnant woman showed ocular recurrence. The municipality of residence, contact with cats during adulthood, and ingestion of unpasteurized milk were shown to be important risk factors. Congenital toxoplasmosis was observed in a pregnancy referred late for treatment. Follow-up of children born to mothers with diagnosed or suspected acute toxoplasmosis is crucial in the management of the changes that toxoplasmosis may cause.     

Bone mineral density in patients with ossification of the posterior longitudinal ligament in the cervical spine

Bone mineral density (BMD) has not been clearly determined in patients with ossification of the posterior longitudinal ligament (OPLL) in the cervical spine. BMD in patients with OPLL was measured in the third vertebral body in the lateral projection and in the distal part of the radius in the anteroposterior projection using dual-energy X-ray absorptiometry (DXA). Patients with OPLL had significantly higher BMD than healthy controls in both the lumbar spine and radius. Observing BMD by gender and age group, high BMD was recognized especially in female patients over 60 years of age. Significantly increased BMD was observed in patients with ankylosing spinal hyperostosis (ASH) in addition to OPLL. These findings suggest that patients with OPLL may tend to develop systemic hyperostosis, leading to the pathological ectopic ossification observed in OPLL.

Communication Disparity Between the Bereaved and Others: What Hurts Them and What Is Unhelpful? A Nationwide Study of the Cancer Bereaved

Context

The importance of communication between the cancer bereaved and others has been emphasized, but little is known about the more problematic aspects of this communication such as “unhelpful communication.”

Bronchoesophageal fistula in a patient with untreated malignant lymphoma

Bronchoesophageal fistulae associated with lymphomas are generally associated with chemo-radiotherapy. We report here an unusual case of lymphoma with a therapy-unrelated bronchoesophageal fistula. Previously, only 10 similar cases have been reported. A 70-year-old male was diagnosed as having gastric diffuse large B-cell lymphoma in May 1998. In January 1999, he noted a cough after eating and drinking. Because of the presence of a febrile temperature, productive cough and dyspnea, he was referred to our hospital and diagnosed as having aspiration pneumonia. Antibiotics did not improve his symptoms. When tracheal intubation was performed with bronchoscopy, a bronchoesophageal fistula was revealed. Malignant lymphoma cells were found around the fistula in the biopsy specimen. The patient died of pneumonia after treatment with airway stenting and chemotherapy. Induction of necrosis by chemotherapy or low blood flow with stenting and dopamine probably caused enlargement of the fistula.     

Nasal CPAP improves the quality of life and lessens the depressive symptoms in patients with obstructive sleep apnea syndrome

OBJECTIVE: To assess changes in response to nasal continuous positive airway pressure (CPAP) in patients with obstructive sleep apnea syndrome (OSAS) concerning excessive daytime sleepiness (EDS), depressive state, and quality of life (QOL). PATIENTS AND METHODS: We assessed for EDS using the Epworth sleepiness scale (ESS), for mood using The Zung self-depression scale (SDS), and for QOL using Short-Form 36 (SF-36) in 132 patients with obstructive sleep apnea syndrome (OSAS) and control subjects. Patients had severe OSAS (apnea-hypopnea index, 59.4+/-23.8/h) and were more hypersomnolent and depressed, and had poorer QOL than 38 age- and gender-matched controls. RESULTS: Before treatment most QOL domains in the SF-36 were significantly associated with patients' SDS scores. With nasal CPAP, ESS and SDS scores were respectively decreased from 9.7+/-4.5 to 4.0+/-2.4 (p<0.0001) and from 49.2+/-10.4 to 45.1+/-9.6 (p<0.0005). Total SF-36 score and scores for seven of eight domains were increased significantly with treatment. Thus, nasal CPAP lessens EDS and depression, and improves QOL, in patients with severe OSAS. Further, magnitudes of changes in total SF-36 scores and in five of eight domains correlated significantly with magnitude of change in SDS score upon nasal CPAP treatment. No relationship was evident between treatment-associated score changes in SF-36 domains and ESS score change. CONCLUSION: Although patients with severe OSAS have poorer QOL than control subjects, nasal CPAP appears to improve QOL by alleviating depression.     

Comparison of the diagnostic power of transthoracic and transesophageal echocardiography to detect ruptured chordae tendineae

Preoperative information concerning the severity and etiology of MR is very important for selecting the most appropriate surgical strategy. Ruptured chordae tendineae (RCT) are one of the most important preoperative findings. We compared the diagnostic power of transesophageal echocardiography (TEE) and transthoracic echocardiography (TTE) to detect RCT in patients with MR. We studied 61 patients with MR (30 men, 31 women; mean age, 61 ± 12 years) who underwent mitral valve repair or replacement. Both TTE and TEE were performed before the operations, and the sensitivity and specificity of TTE and TEE to detect RCT were determined. In addition, other factors that influenced the detection of RCT by these two methods were investigated. At the time of an operation, RCT was confirmed in 39 of 61 cases. Transesophageal echocardiography had a higher sensitivity than TTE (74% versus 44%; P = 0.006) to detect RCT, although the specificity was not significantly different. In patients with a body mass index (BMI) > 22 (P = 0.023) or MR grade 4 (P = 0.026), TEE had a significantly higher diagnostic sensitivity than TTE, although there was no significant difference in patients with BMI < 22 or MR grade ≤ 3. In the lateral and medial segments of the mitral valve, TEE had a significantly higher diagnostic sensitivity to detect RCT than TTE (P = 0.0012), although there was no significant difference in the middle segments. There was no significant difference between TTE and TEE with respect to the sensitivity to detect RCT in myxomatous mitral valves. Although the sensitivity of TEE was higher than that of TTE to detect RCT, it was affected by BMI, MR grade, the RCT-presenting segments, and the etiology of MR.     

Eyestrain induced by stereogram on 3-D display--differences between types of correction

PURPOSE: We investigated eyestrain in normal subjects induced by gazing at a random-dot stereogram on a parallax barrier system 3-D display. METHODS: The 41 subjects were divided into 4 groups according to the type of correction. Near point of accommodation, accommodative relaxation, and contraction times were measured with an accommodo-polyrecorder before and after a stereoscopic visual load, and 15 min and 30 min after a rest. The subjective symptoms were assessed by a 7-point rating questionnaire at the same time as the measurements. RESULTS: After 15 min of sustained visual load, the near point of accommodation was prolonged significantly in the groups without correction and with soft contact lenses(SCL), and accommodative contraction and relaxation times were significant delayed in the groups without correction, with hard contact lenses(HCL), and with SCL but not in the group with spectacles. These changed values of accommodation returned to their previous value following the rest. Significant increase in the rating questionnaire was found in the subjective symptoms of "eyestrain", "eye heaviness", "clouding", "eye dryness" and "irritation of eyes" after loading in the groups without correction, with HCL, and with SCL. In the spectacle group, there was no significant change in the subjective symptoms of "clouding" and "eye dryness". CONCLUSION: From these results, it is concluded that gazing at stereoscopic images on the parallax barrier system 3-D display causes severer eyestrain in cases of correction with contact lenses and in uncorrected cases than in cases with spectacles.     

A structural model of the relationships among self-efficacy,psychological adjustment,and physical condition in Japanese advanced cancer patients

We made detailed research for relationships among physical condition, self-efficacy and psychological adjustment of patients with advanced cancer in Japan. The sample consisted of 85 (42 males and 43 females) advanced cancer patients. Interviews were conducted with some measurement scales including the Self-efficacy scale for Advanced Cancer (SEAC), and the Hospital Anxiety and Depression Scale (HADS). Karnofsky Performance Status (KPS) and medication status were also recorded from the evaluation by physicians. We used structural equation modeling (SEM) for statistical analysis. The analysis revealed that the model, including three self-efficacy subscales, depression, anxiety, KPS, meal-, liquid-intake, prognosis and three latent variables: 'Self-efficacy', 'Emotional Distress', and 'Physical Condition,' fit the data (chi-square(24)=28.67, p=0.23; GFI=0.93; CFI=0.98; RMSEA=0.05). In this model, self-efficacy accounted for 71% of the variance in emotional distress and physical condition accounted for 8% of the variance in self-efficacy. Overall, our findings suggest clearly that close relationships existed among physical condition, self-efficacy and emotional distress. That is, patients in good physical condition had a high self-efficacy, and patients with high self-efficacy were less emotionally distressed. These results imply that psychological intervention which emphasizes self-efficacy would be effective for advanced cancer patients.     

Desire for death and requests to hasten death of Japanese terminally ill cancer patients receiving specialized inpatient palliative care

A desire for death and requests to hasten death are major topics in recent medical literature. The aim of this study was to clarify the bereaved family-reported incidence and reasons for desiring death and requests to hasten death during the whole course of terminally ill cancer patients receiving specialized palliative care in Japan. A nationwide questionnaire survey of 500 primary caregivers yielded a total of 290 responses (effective response rate, 62%). Sixty-two (21%) families reported that the patients had expressed a desire to die, and 29 (10%) families reported that the patients had requested that death be hastened. The major reasons for desiring death and requests to hasten death were: burden on others, dependency, meaninglessness, unable to pursue pleasurable activities, general malaise, pain, dyspnea, concerns about future distress, and wish to control the time of death. No intolerable physical symptoms were reported in 32% and 28% of the patients who desired death and those who requested to hasten death, respectively. Concerns about future distress and wishes to control the time of death were significantly more likely to be listed as major reasons for desiring death in patients who requested that death be hastened than those who did not. A desire for death and requests to hasten death are not uncommon in terminally ill cancer patients receiving specialized inpatient palliative care in Japan. More intensive strategies for general malaise, pain, and dyspnea near the end of life, and for feelings of being a burden, meaninglessness, and concerns about future distress would alleviate the serious suffering of patients with a desire for death. However, some patients with a strong wish to control the time of death might not receive benefit from conventional palliative care.
