We present a case of recurrent cutaneous nocardiosis following a high pressure air injection injury which was treated conservatively. The patient subsequently developed multiple chronic granulomatous nodules in the palm and dorsum of the hand requiring repeated surgical debridements and long term antibiotics for complete resolution. Some reports suggest that ...

OBJECTIVE: This article reports the first application of subatmospheric pressure management to a deep, partial-thickness human thermal burn. METHODS: After cleaning the wound, the decision was made to treat the hand and distal forearm with subatmospheric pressure (V.A.C., KCI, Inc, San Antonio, Tex). The sponge was applied directly to the ...

In Caucasians, the range of normal intracompartmental pressure of the leg is from 0 mmHg to 15 mmHg. In the literature, such measurements have not been done in Africa to identify normal leg intracompartmental pressures. We have sought to identify the normal range of pressures in such a population of ...

In vitro studies show that new miniature cryoprobes are suitable for cryoablation of bone tissue. The aim of this animal trial on 24 sheep was to examine the perioperative complications, particularly the danger of embolism, of cryoablation when using miniature cryoprobes. Cryoablations with 2 freeze-thaw cycles each were carried out ...

Pressure ulcers are a serious health issue, leading to clinical, financial, and emotional challenges. Numerous treatment modalities are available to promote wound healing, yet clinicians may be unsure how to incorporate these treatment options into an overall plan of care for the patient with a pressure ulcer. A consensus panel ...

A common mode of limb suspension for transtibial amputees is the pin liner/shuttle lock system. Despite its popularity, some clinicians question its use because of observed daily and chronic changes to the residual limb. For this study, we measured limb interface pressures during ambulation with pin and suction suspension systems. ...

Negative pressure wound therapy uses a reticulated sponge and subatmospheric pressure to facilitate healing of a variety of wounds. The therapy appears to assist wound healing by decreasing wound bacterial burden and edema while facilitating granulation tissue formation. The latest development in negative pressure wound therapy allows clinicians to instill ...

BACKGROUND: We hypothesized that pressure stimulates colon cancer cell adhesion to surgical wounds. METHODS: We quantitated adhesion of murine 26/51 transplantable colon cancer cells by cell counting or chromium 51-labeling. Tumor cells were added to murine surgical wounds after 30 minutes preincubation under ambient or 15 mm Hg increased pressure. ...

OBJECTIVE: The watertight closure of the dura mater is fundamental to intracranial procedures in neurosurgery. Nevertheless, for any given operator and type of suture, it is still not certain which suturing technique affords the most watertight dural closure. We have developed a laboratory model that allows us to compare the ...

During total hip arthroplasty, the intraoperative cementation pressure was measured inside one of the acetabular anchorage holes. Patients were randomized to pressurization of cement with either a conventional pressurizer or a sequential method including individual pressurization of each anchorage hole. The pressure was correlated to the cement penetration measured on ...

BACKGROUND: Tape stripping is a common method for investigating stratum corneum (SC) physiology as well as bioavailability and bioequivalence of topical drugs. OBJECTIVES: To investigate the influence of procedures (anatomical site, pressure, pressure duration, tape removal rate) inherent in each stripping protocol on changes in skin physiology. METHODS: Tape stripping ...

Topical negative pressure is gaining popularity as an acute and chronic wound management technique. In general, foam dressing is applied to the wound surface to maintain negative pressure. Due to the potential for clogging by the foam dressing, topical negative pressure cannot be used when there is a high volume ...

Transcutaneous partial pressure of oxygen (TcPO2) predicts wound healing in critical ischemia. However, no studies have controlled for the effect of wounds on TcPO2. In this study, in 24 hip or knee arthroplasty cases without vascular disease, TcPO2 was measured preoperatively at the incision site, contralaterally, and at a reference ...

Because the skin is the athlete's first line of defense, it is exposed to friction and pressure in nearly every athletic setting. Whether applied acutely or chronically, friction and pressure often cause skin trauma, such as abrasions, chafing, calluses, blisters, talon noir (black heel), and acne mechanica. Sports medicine clinicians, ...

In this cadaver study, we compared 2 different acetabular cement pressurizers (Exeter and Bernoski type) in paired human acetabula with simulated intraosseous bleeding. Pressure transducers were used to record intra-acetabular pressures during pressurization. Anteroposterior radiographs of the entire specimens were taken. Subsequently, standardized 3-mm-thick sections were cut through the acetabula, ...
