Inpatient admissions for interventional radiology: philosophy of patient management

As an alternative to performing interventional radiology on inpatients under the care of internists and surgeons, the authors have established a cardiovascular radiology admitting service for well-screened, elective patients. The patients are admitted under the care of a cardiovascular radiology fellow and a staff physician. From April 1982 to December 1983, 133 patients were admitted to the service. Patients are cared for in a surgical ward or in an intermediate unit, as determined by the clinical situation. Advantages of this approach include a broader patient referral base, improved rapport with clinical colleagues and patients, improved follow-up data, and rapid evaluation and treatment, resulting in short hospital stays. The major disadvantages involve the commitment of time and staff necessary to provide quality care. The concept of the interventional radiologist in the role of admitting physician has important implications in terms of negotiations for additional financial compensation, commensurate with the skill and time required for performing these procedures and caring for the patient.     

Stress and anxiety among mothers of premature infants in a Malaysian neonatal intensive care unit

Objective: This study aims to determine maternal stress and anxiety as perceived by mothers whose premature infants were admitted to the neonatal intensive care unit (NICU) and to identify maternal stress and its relationship with maternal and infant characteristics and anxiety.

Background: Vulnerable premature infants commonly require special care in the NICUs. In most cases, prolonged hospitalization results in stress and anxiety for the mothers.

Methods: A non-probability convenience survey was used in a public hospital, with 180 mothers completing the 26-item Perceived Stress Scale (PSS) and a 40-item State-Trait Anxiety Inventory (STAI).

Results: 56.5% of mothers had high levels of stress, 85.5% of mothers had a high level of state-anxiety and 67.8% of mothers had a high level of trait-anxiety. The stress experienced by these mothers had a significant relationship with anxiety, and was found to be associated with state and trait anxiety levels, but not with maternal and infant characteristics.

Conclusion: Mothers in this setting revealed high levels of stress and anxiety during their premature infants’ NICU admission. An immediate interventional programme focusing on relieving mothers’ anxiety and stress is needed to prevent maternal stress and anxiety at an early stage.     

Antitumor activity of pan‐HER inhibitors in HER2‐positive gastric cancer

Molecularly targeted therapy has enabled outstanding advances in cancer treatment. Whereas various anti‐human epidermal growth factor receptor 2 (HER2) drugs have been developed, trastuzumab is still the only anti‐HER2 drug presently available for gastric cancer. In this study, we propose novel treatment options for patients with HER2‐positive gastric cancer. First, we determined the molecular profiles of 12 gastric cancer cell lines, and examined the antitumor effect of the pan‐HER inhibitors afatinib and neratinib in those cell lines. Additionally, we analyzed HER2 alteration in 123 primary gastric cancers resected from Japanese patients to clarify possible candidates with the potential to respond to these drugs. In the drug sensitivity analysis, both afatinib and neratinib produced an antitumor effect in most of the HER2‐amplified cell lines. However, some cells were not sensitive to the drugs. When the molecular profiles of the cells were compared based on the drug sensitivities, we found that cancer cells with lower mRNA expression levels of IGFBP7, a tumor suppressor gene that inhibits the activation of insulin‐like growth factor‐1 receptor (IGF‐1R), were less sensitive to pan‐HER inhibitors. A combination therapy consisting of pan‐HER inhibitors and an IGF‐1R inhibitor, picropodophyllin, showed a notable synergistic effect. Among 123 clinical samples, we found 19 cases of HER2 amplification and three cases of oncogenic mutations. In conclusion, afatinib and neratinib are promising therapeutic options for the treatment of HER2‐amplified gastric cancer. In addition to HER2 amplification, IGFBP7 might be a biomarker of sensitivity to these drugs, and IGF‐1R‐targeting therapy can overcome drug insensitiveness in HER2‐amplified gastric cancer.     

Upper genital schistosomiasis mimicking an ovarian tumour

Schistosomiasis is a widely prevalent disease in the world and usually involves the gastro-intestinal and urinary tract. The involvement of the female genital tract has been well-established in S. haematobium infections and is rare with S. japonicum infections. This case involves a Filipino female who was admitted to the University Hospital Kuala Lumpur for right iliac fossa pain and was diagnosed initially as acute appendicitis. Ultrasound showed a multi-septated pelvic cyst leading to a provisional diagnosis of ovarian torsion. Intraoperatively a right parovarian cyst was detected and removed. Histology revealed a congested cyst wall with areas of haemorrhage with several viable and calcified eggs of S. japonicum measuring 85 microns x 62 microns. Within the cystic cavity blood admixed with eggs were seen. Confirmation was carried out by using the indirect haemagglutination (IHA) test. This is a first report of upper genital schistosomiasis mimicking an ovarian tumour.     

蒙药如达溃疡散对大鼠乙酸性胃溃疡及其血清促胃液素的影响

目的:探讨如达溃疡散对大鼠乙酸性胃溃疡的作用及对其血清促胃液素(gastrin)含量的影响.方法:采用乙酸法复制胃溃疡模型,将大鼠随机分为对照组、如达溃疡散组、雷尼替丁组,观察如达溃疡散对大鼠胃溃疡的作用,并检测其对大鼠血清中促胃液素含量的影响.结果:与对照组相比,如达溃疡散能明显抑制溃疡的发生,抑制血清促胃液素含量.结论:如达溃疡散具有抗胃溃疡的作用,其作用机理可能是通过抑制促胃液素释放,进一步减少胃酸分泌来实现的.
