Interpeduncular fossa sign: CT criterion of subarachnoid hemorrhage

A retrospective study of 100 cerebral computed tomography scans interpreted as displaying subarachnoid hemorrhage was undertaken to determine the frequency of blood in the interpeduncular fossa as a useful radiographic sign. The results indicate that the interpeduncular fossa sign is second only to blood in the Sylvian fissure-circular sulcus area as a reliable indicator of subarachnoid hemorrhage on CT scans.     

MR imaging of the scrotum: normal anatomy

High-resolution magnetic resonance (MR) imaging with a surface coil was utilized to evaluate the normal scrotum. Scrotal contents, spermatic canal, and inguinal regions were visualized within the same field of view. Differences in signal intensity in the testis, epididymis, tunica albuginea, fluid, fat, and spermatic cord allowed for clear delineation of these structures in detail. The high contrast and spatial resolution of MR imaging, coupled with the wide field of view and absence of ionizing radiation, make MR imaging well suited for evaluation of the scrotum.     

N-(6,6-二甲基-2-庚烯-4-炔基)-N-甲基-α-取代-1-(4-取代)萘甲胺类的合成及抗真菌活性

根据氮唑类和烯丙胺类抗真菌化合物的构效关系、作用机理。设计合成了30个N-(6,6-二甲基-2-庚烯-4-炔基)-N-甲基-α-取代-1-(4-取代)萘甲胺类化合物。初步体外抑菌试验结果表明,大多数目标化合物对八种试验菌株都有不同程度的抗真菌活性。化合物Ⅰ_1a的真菌活性大致与克霉唑相当,对白念珠菌的活性明显高于naftifine和terbinafine,但对其它七种菌株的活性均不及naftifine和terbinafine;化合物Ⅲ_1a对八种试验菌株的活性均与terbinafine相当。     

Causes of jaundice during hepatic artery infusion chemotherapy

Jaundice develops in many patients with liver metastases from colorectal adenocarcinoma during hepatic arterial infusion chemotherapy (HAIC). The usual cause is thought to be hepatotoxicity from the chemotherapeutic agent or biliary obstruction from progressive neoplastic disease. The authors evaluated the abdominal computed tomography and ultrasound examinations performed on 49 patients who were jaundiced during long-term HAIC. In only one patient was diffuse intrahepatic biliary dilatation caused by an obstructing mass in the porta. Two patients had metastatic hepatic lesions causing focal biliary obstruction. Intrahepatic dilatation without an obstructing mass occurred in 20 patients. Percutaneous or endoscopic cholangiograms were commonly interpreted prospectively as showing extrinsic compression by metastases, but no mass was confirmed on imaging studies. Seven patients had focal intrahepatic ductal dilatation from stricture without an associated mass. The remaining 19 patients had normal-caliber ducts; their jaundice was caused by chemical hepatitis. This series suggests that the most common causes of jaundice in these patients are chemical hepatitis and common bile duct stricture, complications of intraarterial chemotherapy, rather than neoplastic obstruction. Stricture formation may be confused with extrinsic compression on direct cholangiograms.

Managing chronic headaches in the clinic

Chronic daily headache (CDH), which is often linked to a history of migraine, tension-type headache and the abuse of headache medications, and cluster headache are the best known of the chronic headaches. These headaches may not be well recognised or well treated in primary care. This article outlines the development of management algorithms for these headache subtypes, designed for use by the primary care physician with an interest in headache. Principles of care for chronic headaches include implementation of screening procedures, differential diagnosis, tailoring of management to the individual's needs, proactive follow-up and a team approach to care. These principles can be customised to the headache subtype by the selection of appropriate therapies. The optimal treatments for CDH include physical therapy to the neck if there is any stiffness there, withdrawal of abused medications and treatment of any subsequent withdrawal symptoms and headache prophylaxis, together with the provision of acute medications as rescue therapy. Optimal treatments for cluster headache include short- and long-term prophylaxis to prevent the headaches developing and acute medications for use as rescue. If treatment is ineffective, alternative medications can be provided at follow-up, with the possibility of referral for refractory patients.     

Clinical Care Costing Method for the Clinical Care Classification System™

PURPOSE: To provide a means for calculating the cost of nursing care using the Clinical Care Classification System (CCCS). DATA SOURCES: Three CCCS indicators of care components, actions, and outcomes in conjunction with Clinical Care Pathways (CCPs). DATA SYNTHESIS: The cost of patient care is based on the type of action time multiplied by care components and nursing costs. CONCLUSIONS: The CCCM for the CCCS makes it possible to measure and cost out clinical practice. IMPLICATIONS FOR PRACTICE: The CCCM may be used with CCPs in the electronic patient medical record. The CCPs make it easy to track the clinical nursing care across time, settings, population groups, and geographical locations. Collected data may be used many times, allowing for improved documentation, analysis, and costing out of care.
