The efficacy of fluconazole in treating prosthetic valve endocarditis caused byCandida glabrata: Report of a case

A case of active prosthetic valve infective endocarditis (PVE) due toCandida glabrata was successfully treated by the systemic administration of fluconazole. A 66-year-old Japanese man with infective endocarditis of unknown etiology underwent aortic and mitral valve replacement to treat severe aortic and mitral regurgitation associated with multiple organ failure. Postsurgical cultures of arterial blood were repeatedly positive forC. glabrata, and therefore fluconazole was administered either intravenously or orally at a dose of 400 mg/day for 46 days. During that time the signs of inflammation including fever such as an elevated white blood cell count and the presence of C-reactive protein (CRP) all improved while the blood cultures became negative. Fluconazole is thus considered to be effective in treating PVE caused byC. glabrata. When administering this treatment, it is also important to monitor the patient's renal and liver function.

A new respiratory valve system for measuring oxygen uptake during swimming

We describe a new respiratory valve system with minimal dead space, which allows measurement of ventilation and oxygen uptake during swimming. The device offers considerable advantages in efficiency and accuracy over current equipment, and can be used in conjunction either with a miniaturized telemetry system for oxygen uptake measurement or with a conventional system. The valve has a low airflow resistance, a small dead space (15 ml), and an electrically operating, closed-circuit pump to remove excess water from the expiratory tube. The external form and the buoyancy of the valve have been hydrostatically and hydrodynamically designed to reduce drag and to ensure a correct mass in the water. To obtain this result a very sophisticated material, carbon fibre, has been utilized. Our studies showed that this respiratory system is ideal for obtaining valid and reliable values of oxygen uptake during swimming, even at high speed and in endurance swimming tests.     

鼻部不同部位缺损的修复

目的：探讨鼻部分或全部缺损的手术修复。方法：根据鼻部不同范围的缺损选择不同的方式进行修复，包括邻近皮瓣、岛状皮瓣、复合组织游离移植等。结果：31例鼻部缺损组织瓣修复中鼻唇沟皮瓣13例，邻近滑行皮瓣8例，额部岛状皮瓣5例，耳廓复合组织游离移植5例均成活。术后鼻外形均满意。结论：鼻缺损修复方式较多，应根据缺损的部位，范围选择不同的修复方式。     

带真皮下血管网超薄皮瓣血运重建的实验研究（三）超薄皮瓣的再血管化与血供变化

以猪作为动物模型，对带真皮下血管网超薄皮瓣的血运重建规律进行了探讨。以超薄皮瓣为实验组，保留真皮下血管网皮片为对照组，按自身配对原则随机分为６个组。通过荧光素显色，透明标本，组织学，明胶墨汁灌注过程中超薄皮瓣的染色情况等观察，发现超薄皮瓣的再血管化发生在术后第５天，至第７天新生血管通过塑形趋于成熟。它既发生在皮瓣与受床之间，又发生在皮瓣与创缘之间，而且由皮瓣成活部分远端渐至近端。     

Management of chronic calcaneal osteomyelitis with pull-through abductor hallucis muscle flap -a report of three cases

Three patients who had chronic osteomyelitis of the calcaneus were treated with radical debridement of all involved soft tissue and bone and obliteration of dead space with a pull-through abductor hallucis brevis muscle flap. Two patients had calcaneal osteomyelitis without soft tissue loss resulting from previous comminuted calcaneal fractures while a third patient had a large soft tissue defect and calcaneal osteomyelitis resulting from a destructive infection. All of the patients had undergone several surgical procedures for treatment of the osteomyelitis with histories ranging 18 months to 30 months. Following treatment with the pull-through muscle flap there has been no recurrence over the longterm (>two years). We believe that radical removal of all contaminated tissue and immediately coverage with a muscle flap provides an effective single stage treatment of chronic calcaneal osteomyelitis.

Ambulatory 24-hour esophageal pH monitoring

If 24-hour esophageal pH monitoring is to be a useful diagnostic tool, it must reliably discriminate gastroesophageal reflux patients despite daily variations in distal esophageal acid exposure. To address this issue, we studied 53 subjects (14 healthy normals, 14 esophagitis patients, and 25 patients with atypical symptoms) with two ambulatory pH tests performed within 10 days of each other. Intrasubject reproducibility of 12 pH parameters to discriminate the presence of abnormal acid reflux was determined. As a group, the parameters of percent time with pH<4 (total, upright, recumbent) were most reproducible (80%). Therefore, a subject was defined as having gastroesophageal reflux disease if at least one of these three values were abnormal. Intrasubject reproducibility for the diagnosis of reflux disease was 89% for the entire sample. Among subsets, the reproducibility was 93% for the normals and esophagitis patients and 84% for the atypical symptom patients. Total percent time with pH<4 was the single most discriminate pH parameter (85%) and nearly equaled that of the three combined parameters (89%). The intrasubject variability of this parameter was determined by the mean ±2sd of the relative differences between the two test results for all 53 subjects. Total percent time with pH<4 may vary between tests by a factor of 3.2-fold or less (218% higher to 69% lower). We conclude: (1) ambulatory 24-hr esophageal monitoring is a reproducible test for the diagnosis of gastroesophageal reflux disease; and (2) the large intrastudy variability in 24-hr total acid exposure may limit this test's usefulness as a measurement of therapeutic improvement.Supported, in part, by Public Health Services Grant AM 34200-01A1 from NIADDIK.
