BACKGROUND: Hordeolum is an acute, purulent inflammation of the eyelid margin usually caused by obstructed orifices of the sebaceous glands of the eyelid. The condition, which affects sebaceous glands internally or externally, is common. When the meibomian gland in the tarsal plate is affected, internal hordeolum occurs, while when the glands of Zeis or Moll associated with eyelash follicles are affected, external hordeolum, or stye occurs. The onset of hordeolum is usually self limited, and may resolve in about a week with spontaneous drainage of the abscess.

A novel three-element radiofrequency hyperthermia system, consisting of paired multiple-feed inductors positioned between two large capacitor plates and a moveable grounding point, was designed and constructed. The spatial orientation of these elements and the phase of the current flowing through them can be varied to produce asymmetric magnetic field patterns resulting in development of asymmetric eddy current patterns orthogonal to the magnetic lines of force. These patterns could be further focused by manipulation of the capacitor plates and grounding point.

Critical modifications have been made in the grounded elements of a previously reported hybrid radiofrequency heating system with inductive, capacitive, and grounded elements designed for deep focal heating. These modifications facilitate introduction of the ground probe, the single invasive element of the system, into animals and humans.

OBJECTIVE: This study sought to evaluate whether surgical clips affect tissue conductivity and thereby alter the induction of radiofrequency ablation lesions and to determine whether therapy is safe after previous placement of clips in the liver. MATERIALS AND METHODS: An ex vivo porcine hepatic model was used. Three clips were placed around a radiofrequency electrode at 10, 20, and 30 mm from the point of insertion. Clips were arranged in a plane either perpendicular or parallel to the electrode track.

PURPOSE: Radiofrequency (RF) tumor ablation has become an accepted treatment modality for tumors not amenable to surgery. Skin burns due to ground pad heating may become a limiting factor for further increase in ablation zone dimensions and generator power. We investigated a method were groups of ground pads are sequentially activated to reduce skin heating. METHODS: We compared conventional operation (i.e. simultaneous connection of all pads) to sequentially switched activation of the pads where different pad combinations are active for periods of approximately 0.3 - 8 s.

Bakera, a steam bath prepared with various plants, is a traditional method used in Minahasa (North Sulawesi, Indonesia) for recuperation after childbirth. Semi-structured interviews were conducted with 14 midwives and 166 mothers in different villages of Minahasa, in order to document the preparation and plants used for the bakera. Overall, the use of 60 different plant species for the bakera was recorded. Among the 10 most frequently cited bakera plants, eight are essential oil plants, which are usually cultivated in the kitchen gardens and often used as spices.

This review presents the common diseases associated with superficial venous insufficiency of the leg. These include varicose veins, swelling, skin damage and ulceration. The benefits and rationale behind treatment are discussed, followed by the historical advances from ancient mortality and prayer to the modern endovenous revolution. Finally, an overview of modern treatment options will discuss the evidence supporting the gold standard of endothermal ablation and the cost effectiveness of treatment at this time of challenging resource limitation.

BACKGROUND: Although massage is one of the most popular complementary and alternative medical (CAM) treatments for anxiety, its effectiveness has never been rigorously evaluated for a diagnosed anxiety disorder. This study evaluates the effectiveness of therapeutic massage for persons with generalized anxiety disorder (GAD). METHODS: Sixty-eight persons with GAD were randomized to therapeutic massage (n=23), thermotherapy (n=22), or relaxing room therapy (n=23) for a total of 10 sessions over 12 weeks. Mean reduction in anxiety was measured by the Hamilton Anxiety Rating Scale (HARS).

PURPOSE: Infrared heat, a transient receptor potential vanilloid type-3 (TRPV3) sensitive stimulus, may have potential physiological effects beneficial to treating metabolic syndrome. MATERIALS AND METHODS: Obesity prone (OP) and obesity resistant (OR) rats were fed for seven days on a high-fat diet. Heat treated OP rats were exposed twice daily to infrared light for 20 min each, separated by 80 min of rest. Food intake, blood pressure, blood glucose, and body weight measurements were taken daily and compared between treated OP rats, untreated OP rats, and OR controls.

PURPOSE: Hyperthermia enhances cytotoxic effects of chemotherapeutic agents such as cisplatin. However, the underlying molecular mechanisms remain unclear. We hypothesised that hyperthermia increases cisplatin accumulation and efficacy by modulating function of copper transport protein 1 (Ctr1), a major regulator of cellular cisplatin uptake. We examined the significance of Ctr1 in the synergistic interaction between hyperthermia and cisplatin. We assessed the importance of cisplatin- and hyperthermia-induced Ctr1 multimerisation in sensitising cells to cisplatin cytotoxicity.
