Functional constipation as a risk factor for pyelonephritis and recurrent urinary tract infection in children.

Aim: Acute pyelonephritis is one of the most common bacterial infections in childhood. This potentially serious condition can lead to renal scarring, loss of kidney function and hypertension. The aim of this study was to identify risk factors associated with pyelonephritis in children without kidney or urinary tract abnormalities.

High-Frequency (20 MHz) Focused Ultrasound: A Novel Method for Noninvasive Tattoo Removal.

Alternatives or complements to laser tattoo removal are needed. Laser removal requires 8-12 sessions and can easily take longer than a year. Some colors cannot be removed, and scars may appear.

Comparison and characteristics of children successfully treated for daytime urinary incontinence.

Introduction: Daytime urinary incontinence (DUI) is defined as an involuntary leakage of urine during daytime in children 5 years or older. It is a common disorder in the pediatric population most often caused by an overactive bladder (OAB). A stepwise approach is recommended in the treatment of DUI, with standard urotherapy (SU) being first line treatment followed by pharmacological treatment when SU is unsuccessful.

Removal of Common Warts by High-Intensity Focused Ultrasound: An Introductory Observation.

Therapies of common warts are cumbersome and not very effective. Recurrences are common. A new 20 MHz high-intensity focused ultrasound (HIFU) method is introduced as a new potential treatment modality.

High-frequency (20 MHz) high-intensity focused ultrasound: New ablative method for color-independent tattoo removal in 1-3 sessions. An open-label exploratory study.

Background: High-intensity focused ultrasound (HIFU) operating at 20 MHz is new and potentially applicable to ablative tattoo removal. The method was documented safe and rational in preclinical testing.

Materials And Methods: High-intensity focused ultrasound was introduced to subjects when lasers and dermatome shaving had failed or caused side effects.

High-frequency (20 MHz) high-intensity focused ultrasound: New Treatment of actinic keratosis, basal cell carcinoma, and Kaposi sarcoma. An open-label exploratory study.

Background: Skin cancer is common, growing, challenging, and in need of progress in early-stage treatment. 20 MHz high-intensity focused ultrasound (HIFU) is new and applied to actinic keratosis (AK) and skin cancers for the first time. HIFU of lower frequency is already used in the treatment of internal cancers.

High-frequency (20 MHz) high-intensity focused ultrasound system for dermal intervention: A 12-week local tolerance study in minipigs.

Background: High-intensity focused ultrasound (HIFU) operating at 20 MHz is new and applicable to skin. Details of use and instrumentation are not documented.

Materials And Methods: A GLP compliant 12-week study of Göttingen minipigs (n = 3) was undertaken.

High-frequency (20-MHz) high-intensity focused ultrasound (HIFU) system for dermal intervention: Preclinical evaluation in skin equivalents.

Background: High-intensity focused ultrasound (HIFU) for non-invasive treatment of a range of internal pathologies including cancers of major organs and cerebral pathologies is in exponential growth. Systems, however, operate at relatively low frequencies, in the range of 200-2000 kHz as required for deep axial penetration of the body. HIFU utilizing frequencies in excess of 15 MHz has so far not been explored, but presents an opportunity to extend the HIFU modality to target specific dermal lesions and small animal research.
