Method and device for producing an adapted travel treatment plan for administering a medicine in the event of a long-haul journey
InactiveUS20020147135A1Facilitates reliable actionTicket-issuing apparatusPeptide/protein ingredientsMedicineTime zone
Patients with certain chronic diseases such as diabetes require medical treatment according to a set time-related treatment plan. Such a treatment plan must be adapted accordingly in the case of long-haul journeys to countries with a time difference. A method for this has the steps of recording an regular treatment plan for administering the medicine, recording the point of departure and destination as well as the time of travel of the long-haul journey, determining the time zone difference between the point of departure and the destination and producing an adapted travel treatment plan based on the regular treatment plan depending on the time zone difference and the time of travel. The invention enables a patient to achieve a structured adaptation of his individual treatment plan to the time difference in the destination country of the journey in a convenient manner.

In a method for diagnosis and treatment of a patient with a tumor relating to prostate cancer, the following steps are implemented. A differential diagnosis of prostate cancer versus prostatitis and / or BPH is conducted on a patient using a cost-effective diagnosis method. If prostate cancer is diagnosed in the patient using a cost-effective measurement method, a characteristic value for the tumor aggressiveness of the prostate cancer is determined. A watchful waiting treatment is implemented with the patient given a characteristic value below a predeterminable first limit value. The size and position of the tumor is determined using a cost-effective method given a characteristic value above the first limit value. A cost-effective ultrasonic theranosis or a conventional therapy is conducted for a size below a second predeterminable limit value. The presence of metastases in the patient is checked, with a cost-intensive method generating image information, for a size above the second limit value. A metastasis treatment is implemented in the event that metastases are present. In the event that no metastases are present, a tumor treatment based on the aforementioned image information generated is implemented.

Disclosed is a process for the treatment of a plant fluid effluent containing odor compounds including an alkyl mercaptan or an alkyl thiol, an amine compound, ammonia, hydrogen sulfide and mixtures thereof by contacting the plant effluent in either a counterflow or cocurrent flow process. In the process, the effluent is contacted with an aqueous solution comprising a peroxyacid compound and one or more essential oils. When contacted with the peroxyacid, odor compounds in the effluent are oxidized and converted from the gaseous phase into a chemically modified highly aqueous soluble phase in the aqueous treatment. In this way, odor removal from the gas is preferred and odor compounds are efficiently transferred into the aqueous treatment solution. The use of such a process produces a significant improvement in odor quality index as measured by a conventional process using an expert panel when compared to conventional treatment methods.

These molds are designed for use in the fabrication of appliances used in orthodontic treatment, particularly, elastic repositioning appliances. However, they may also be used in the fabrication of traditional appliances, such as retainers and positioners, used, for example in the final or finishing stages of an otherwise conventional treatment. The dental molds are comprised of a mold or relief of the patient's soft tissue, such as a palate, facial gingival tissue and / or lingual gingival tissue, and a separate or separable mold or relief of the patient's dental arch having teeth in a desired tooth configuration. Since, the tooth configuration will change as a patient progresses through orthodontic treatment, the relief of the dental arch will be fabricated separately from the relief of the oral soft tissue. Typically, the dental arch relief will be fabricated using rapid prototyping methods. The soft tissue relief may also be fabricated using rapid prototyping, however it may also be fabricated using traditional mold making methods, i.e., casting with plaster or other mold making materials.
