Slow flow of dye in epicardial coronary arteries is not an infrequent finding in patients during routine coronary angiography. The coronary slow flow phenomenon is an angiographic finding characterized by delayed distal vessel opacification in the absence of significant epicardial coronary artery disease. It is speculated that coronary slow flow is a new disease characterized by acute but recurrent perturbations of microvascular function. There are many theories concerning the pathogenesis of migraine. The clinical effectiveness of vasoactive drugs and many investigations on the cerebral blood flow in patients with migraine, strongly support a vascular theory. The relationship between migraine and cardiopathy has not been sufficiently established and controversy exists concerning its favouring role in coronary artery disease. We report a case of an acute migraine attack in a patient who uses triptans (5-HT(1B/1D) receptor agonists). The attack was accompanied by angina-like chest pain with documented ST-segment elevation and slow coronary flow in the absence of any significant obstructive coronary artery disease and no evidence of any major epicardial coronary arterial spasm.  相似文献

Gonadal sex cord stromal tumors contain some of the most morphologically interesting neoplasms of the gonads, and these lead to many important issues in differential diagnosis. Granulosa cell tumors are much more common in females. Unclassified sex cord stromal tumor is rare. We report a case of a 22-year-old woman with acute ruptured unclassified sex cord stromal tumor of the right ovary during pregnancy. The biological behavior of unclassified sex cord stromal tumors resembles that of Sertoli-Leydig cell tumors of intermediate differentiation rather than poorly differentiated tumors, which may have been expected in view of the lack of specific differentiation. This finding is important with regard to postoperative management.  相似文献

The reproductive age covers approximately 1/3 of a woman's life and have many hormone-related problems causing many admissions to gynecology clinics. Beside these pathologies, there are also some respiratory system related diseases making women to admit pulmonology clinics. In this article, we want to focus attention of gynecologists, chest physicians, thoracic surgeons and primary care physicians to these pathologies which could be collected under the same heading "Non-malignant thoracic pathologies of the women of reproductive age".  相似文献

Some helminthic infections, especially nematode infections, may behave as allergens and induce allergic sensitization. In this study, the investigators explored whether infections withSyphacia muris andAspiculuris tetraptera have any effect on the development of allergen-induced cytokine responses and serum total immunoglobulin E (IgE) levels in ovalbumin (OVA)-sensitized rats. Four groups of male Wistar rats were studied. OVA sensitization was generated in 2 groups of rats; the rats in 1 group were infected and those in the other group were not. On day 21 after sensitization, tumor necrosis factor-α, interleukin-10, and total IgE levels in serum samples of rats were measured by enzyme-linked immunosorbent assay. The results showed that average concentrations of tumor necrosis factor-α and interleukin-10 were significantly greater in the group of rats infected with parasites and sensitized to OVA compared with the group uninfected with parasites and sensitized to OVA (P=.043 and P=.046, respectively). Upon comparison of total IgE concentrations, the group of rats infected with parasites and given saline solution showed higher levels compared with the group uninfected with parasites and given saline (P=.004). In conclusion, the investigators were unable to show a protective effect of an existing parasitic infection against the development of allergic sensitization upon exposure to OVA.  相似文献

Synchronous bilateral testicular germ cell tumors (TGCTs) are seen in exteremely rare cases. Although there is still no standard therapy for bilateral TGCTs, bilateral orchiectomy is recommended as the gold standard treatment. Nevertheless, it has some long-term problems, such as infertility and psychosocial difficulties, and thus some clinicians prefer to perform testis-sparing surgery in appropriate cases. We reviewed the first case of bilateral synchronous TGCT with concomittant bilateral diffuse intratubular germ cell neoplasia in a young single patient, who was treated by a left radical orchiectomy and right testis sparing-surgery with following local radiotherapy to the right residual testicular tissue with previous semen cryopreservation to maintain the ability to father children. We supposed that testis-sparing surgery can be a feasible therapeutic alternative to radical orchiectomy in patients with bilateral TGCTs in terms of improving the quality of life and continuing fertility and normal hormonal status with no medications. However, while the long-term effects are not yet known, this type of treatment should be perpormed in carefully selected cases with longlife expectancy.Key Words: Sycnhronous bilateral testis tumor, Intratubular germ cell neoplasia, Testis sparing surgery, Local radiotherapy  相似文献

One form of prolactin (PRL) is macroprolactin with high molecular mass. Many macroprolactinemic patients have no pituitary adenomas and no clinical symptoms of hyperprolactinemia, it is controversial whether macroprolactinemia is a benign condition that does not need further investigation and treatment. In this study, we aimed to compare macroprolactinemic patients (group I) with the true hyperprolactinemic patients (group II) for the presence of pituitary adenoma. We investigated 161 patients with hyperprolactinemia, whose magnetic resonance imaging records of the pituitary were taken. All patients were questioned for irregular menses, infertility and examined for galactorrhea. Patients were screened for macroprolactinemia by polyethylene glycol precipitation, and a recovery of ≤40% and normal monomeric PRL level was taken as an indication of significant macroprolactinemia. Of 161 patients with hyperprolactinemia, 60 (37.26%) had macroprolactinemia. PRL levels of group II were lower than those of group I (P = 0.011), although monomeric PRL levels of group II were higher than those of group I (P = 0.0005). Of 60 macroprolactinemic patients, 16 (26.7%) had pituitary adenomas. The prevalence of pituitary adenomas was lower in group I, compared with group II (P = 0.0005). No significant differences were found between the prevalences of irregular menses and infertility of group I and II (P = 0.084, P = 0.361). Prevalence of galactorrhea in group I was lower than that in group II (P = 0.048). Prevalence of pituitary adenomas in macroprolactinemic patients is lower compared with the true hyperprolactinemic patients, but may be higher than that found in other recent studies and in the general population.  相似文献

Aims and objectives

To explore the conditions for oral handovers between shifts in a hospital setting, and how these impact patient safety and quality of care.

Background

Oral handovers transfer patient information and nursing responsibilities between shifts. Short written summaries of patients can complement an oral handover. How to find the balance between a standardised protocol for handovers and tailoring variations to specific patients and situations is debated in the literature. Oral handovers provide time for discussion, debriefing and problem solving, which can lead to increased team cohesiveness.

Design

This study used a participant observation design.

Method

Fifty‐two undergraduate nursing students conducted 1100 hr of participant observation in seven different units in a hospital in Western Norway from 2014–2015. Field notes were analysed using qualitative content analysis.

Results

Six themes emerged from the data: (i) content and structure of the handover, (ii) awareness of nurses’ attitudes during oral handover, (iii) verbal and nonverbal communication, (iv) distractions, (v) relaying key information accurately , (vi) ensuring quality through oral handovers.

Conclusion

Developing a familiar structure for oral handovers and minimising the use of abbreviations and unfamiliar medical terms promote clarity and understanding. Limiting disturbances during handovers helps nurses focus on the content of the report. Awareness of one's attitudes and the use of verbal and nonverbal communication can enhance the quality of a handover. Time allocated for an oral handover should allow for professional discussions and student supervision. Involving nurse leaders in promoting the quality of oral handovers can impact the quality of care.

Clinical implications

Oral handovers serve many purposes, such as the safe transfer of patient information between shifts and staff education and debriefing, which enhance team cohesiveness.  相似文献

Background: The etiology of fever of unknown origin has changed because of the recent advances in and widespread use of invasive and non-invasive diagnostic tools. However, undiagnosed patients still constitute a significant number.Objective: To determine the etiological distribution and role of non-invasive and invasive diagnostic tools in the diagnosis of fever of unknown origin.Materials & Methods: One hundred patients who were hospitalized between June 2001 and 2009 with a fever of unknown origin were included in this study. Clinical and laboratory data were collected from the patients'' medical records retrospectively.Results: Fifty three percent of the patients were male, with a mean age of 45 years. The etiology of fever was determined to be infectious diseases in 26, collagen vascular diseases in 38, neoplastic diseases in 14, miscellaneous in 2 and undiagnosed in 20 patients. When the etiologic distribution was analyzed over time, it was noted that the rate of infectious diseases decreased, whereas the rate of rheumatological and undiagnosed diseases relatively increased because of the advances in imaging and microbiological studies. Seventy patients had a definitive diagnosis, whereas 10 patients had a possible diagnosis. The diagnoses were established based on clinical features and non-invasive tests for 61% of the patients and diagnostic benefit was obtained for 49% of the patients undergoing invasive tests. Biopsy procedures contributed a rate of 42% to diagnoses in patients who received biopsies.Conclusion: Clinical features (such as detailed medical history-taking and physical examination) may contribute to diagnoses, particularly in cases of collagen vascular diseases. Imaging studies exhibit certain pathologies that guide invasive studies. Biopsy procedures contribute greatly to diagnoses, particularly for malignancies and infectious diseases that are not diagnosed by non-invasive procedures.  相似文献
