中国私立医院风头正劲——华尔街日报作为一家大律师事务所的高级合伙人,庄先生说,他可以很轻松地花7万美元买一辆进口宝马(BMW)车,或1．2 万美元买块Jaeger-LeCoultre金表。但去年,当这位律师患上偏头痛时,他却不得不排着长队,忍受着粗暴的服务,到固营医院去看病。而费用仅仅是6美元。因为是有钱人,庄先生没有透露他的全名。他说宁愿多花点钱,也希望享受到方便舒适的医疗服务。去年底,他     

Pseudodissection of the coronary artery: A variation caused by interventional tools

During PTCA immediate decisions often must be made on the basis of a less than optimum data set. We present a combination of factors which produce an incorrect perception of a coronary artery dissection. This potential must be understood by the interventionalist to avoid misdiagnosis and inappropriate therapeutic maneuvers. © 1993 Wiley-Liss, Inc.     

Resistance exercise training and alendronate reverse glucocorticoid-induced osteoporosis in heart transplant recipients.

BACKGROUND: Immunosuppression therapy with bolus glucocorticoids causes regional osteoporosis in the axial skeleton of heart transplant recipients (HTR). No preventive strategy is generally accepted for steroid-induced bone loss. METHODS: To determine the efficacy of an anti-osteoporosis regimen that combined a bisphosphonate agent (alendronate sodium) with the osteogenic stimulus of mechanical loading, 25 HTRs were randomly assigned either to a group that received alendronate (10 mg/day) for 6 months (ALEN; n = 8), a group that received alendronate (10 mg/day) and performed specific resistance exercises for 6 months (ALEN + TRN; n = 8) or to a non-intervention control group (CONTR; n = 9). Alendronate was initiated at 2 months after transplantation. Bone mineral density (BMD) of the total body, femur neck and lumbar spine (L-2 and L-3) was measured by dual-energy X-ray absorptiometry before and 2, 5 and 8 months after transplantation. Resistance training consisted of lumbar extension exercise (MedX) performed 1 day/week and 8 variable resistance exercises (MedX) performed 2 days/week. RESULTS: Pre-transplantation BMD values did not differ among the 3 groups. BMD of the total body, femur neck and lumbar vertebra were significantly decreased below baseline at 2 months after transplantation in CONTR (-2.6 +/- 0.9%, -5.1 +/- 1.8%, -12.5 +/- 4.2%, respectively), ALEN (-2.8 +/- 0.8%, -5.3 +/- 1.6%, -12.0 +/- 3.9%) and ALEN + TRN groups (-2.7 +/- 1.0%, -5.6 +/- 2.1%, -11.2 +/- 3.7%). CONTR had further significant losses of BMD after 3 and 6 months. ALEN had no further regional BMD losses after initiation of alendronate therapy. ALEN + TRN restored BMD of the whole body, femur neck and lumbar vertebra to within 0.9%, 2.1%, and 3.4% of pre-transplantation levels, respectively. CONCLUSIONS: Resistance exercise plus alendronate was more efficacious than alendronate alone in restoring BMD in HTRs. Our results indicate that anti-osteoporosis therapy in this population should include both an anti-resorptive agent as well as an osteogenic stimulus, such as mechanical loading.     

Cerebrospinal fluid purine metabolites after complex febrile convulsions

Adenosine monophosphate, inosine monophosphate, inosine, adenosine, guanosine, adenine, guanine, hypoxanthine, xanthine and uric acid were determined in cerebrospinal fluid (CSF) of 15 children after complex febrile seizures (CFS) and in 27 after simple febrile seizures (SFS), and compared with those in a control group of 63 children. There was no statistically significant difference between the groups for any of these metabolites, suggesting that CFS and SFS neither significantly disturb the metabolism of nucleotides, nucleosides or bases nor significantly deplete neuron adenosine triphosphate levels.     

Chronic Paroxysmal Hemicrania: Dissociation of the Pain and Autonomic Features

The case of a woman suffering from chronic paroxysmal hemicrania is presented. Most attacks were unilateral and recurred on the same side. On a few occasions, attacks were observed on the contralateral side. In addition, the patient reported some incomplete attacks on the usually symptomatic side with autonomic phenomena, but without pain. That "partial" attacks would exist has been suspected on theoretical ground. This is, however, the first time such attacks have been reported by a patient. Therefore, a double dissociation of the symptomatology seemed to exist: (1) a side shift of attacks, and (2) incomplete("partial") attacks. These unexpected findings occurred after two indomethacin treatment withdrawals. A possible central and "midline" origin of attacks or an indomethacin after-effect or both are discussed as a likely explanation for such a dissociation of symptoms and signs.     

经左颈静脉肝内门腔静脉支架分流术（附12例报告）

为解决肝硬变门脉高压患者在经颈静脉肝内门腔静脉支架分流术中右颈静脉窄或闭的难题，我们做了经左颈静脉途径完成肝内门腔分流术的尝试。自１９９３年７月至１９９５年８月，共１７８例ＴＩＰＳＳ操作中发现１２例右颈静脉狭窄或闭塞。其方法为经左颈内静脉穿刺、插管入路。     

Untersuchung zur Morbidität der indigenen Volksgruppen der Chiquitanos im südlichen Amazonasgebiet

The Chiquitano-tribe lives in the southern Amazonas region in Bolivia, remote from larger towns. A study (n=1514) on morbidity over an one year period (April 1995 till March 1996) and its relation to general and social medicine is given. Most frequently, childreh under 15 years and women in parity age (15–45 years) sought consultation (34,1 %, 42,7 %). Gastrointestinal, respiratoral and gynecological-obstetric diseases were predominant (22,4 %, 16,2 % and 15,7 %). In the dry season, common colds and respiratoral infections represented the major health problem. In the rainy season, infectious diarrhea diseases caused by polluted water as a consequence of extended floods were most frequent. Typical tropical diseases (malaria, Dengue fever, Chagas’ disease, leprosy a.o.) and socially caused diseases (AIDS, dependencies on drugs and alcohol, consequencies of crime) were rarely seen. With respect to severity, 55,8 % of the patients showed mild disorders. More serious diseases were observed in 39, 8 %. 4,6 % of the patients were diagnosed severly ill and needed hospitalization. Epidemiological data on general and social medicine of minorities in developing countries and their actual degree of medical care are important in a shrinking world. The data are useful to estimate medical needs and plan improvements to the health care system especially in rural areas.     

Rapp-Hodgkin Syndrome with Pili Canaliculi

Abstract: A 20-year-old woman and her 12-year-old brother had hypohidrotic ectodermal dysplasia, cleft lip and palate, midfacial hypoplasia with narrow nose from the nasal bridge to the tip, narrow dysplastic nails, and conical teeth and hypodontia, and hypospadias and hypoplastic uvula in the boy. The woman had major underdevelopment of intellectual capacity. The most important hair anomalies in both siblings were sparse eyebrows, pili torti, and pili canaliculi. Some of the pili canaliculi had two canals (pili bicanaliculi), and the cross section for scanning electron microscopy had a quadrangular aspect. This is the seventh family reported with Rapp-Hodgkin ectodermal dysplasia.
