Headache is a common term that causes pain in the region of head, neck, and scalp. It is a neurological disorder. The nerves are tending to be in under stress condition. The main causes of the headache are due to stress, depression, tension, anxiety and due to some climatic changes, etc. Headache is classified into different types. Migraine, cluster headache, sinus, normal headache are some of the types of headache. Most headaches can be treated with some medication and neuro stimulator devices. This paper involves the usage of vibration by non-invasive method on the acupressure point of the human body which can relief the pain. The acupressure point is a pressure point, when used in a correct method will lead to decrease the level of pain. The vibration is provided by the motor vibrator and the frequency of the vibration is controlled by the arduino (Atmega 328). Frequency changes can be monitored by the pc. This vibration based treatment will effectively reduce the pain and also the device is cost effective and more comfortable to the patient.

Photodynamic Therapy (PDT) has become one of the most promising treatment against autoimmune diseases, such as rheumatoid arthritis (RA), as well as in the treatment of different types of cancer, since it is a non-invasive method and easy to carry out. The three main ingredients of PDT are light irradiation, oxygen, and a photosensitizer (PS). Light irradiation depends on the type of molecule or compound to be used as a PS. The concentration of O2 fluctuates according to the medium where the target tissue is located and over time, although it is known that it is possible to provide oxygenated species to the treated area through the PS itself. Finally, each PS has its own characteristics, the efficacy of which depends on multiple factors, such as solubility, administration technique, retention time, stability, excitation wavelength, biocompatibility, and clearance, among others. Therefore, it is essential to have a thorough knowledge of the disease to select the best PS for a specific target, such as RA. In this review we will present the PSs used in the last three decades to treat RA under PDT protocol, as well as insights on the relevant strategies.

Atherosclerosis is a form of cardiovascular disease that is a major contributing factor to death and disability worldwide. This study uses computational fluid dynamics (CFD) models as a cost effective and non-invasive method to determine the location and condition of atherosclerosis segments on the arterial wall. It also investigates changes in the abdominal aorta geometry including the inner and outer diameters, the length of the disease segments and the thickness of the arterial wall on the development of disease. Three groups of unhealthy conditions are assumed with each group having eight cases, which are compared to the control case of healthy condition. An invasive catheter pulsatile blood flow is imposed at the ascending aorta and pressure waveforms data is imposed at the four outlets of the aorta and also used to validate the present models. The results show that the stress phase angle at the brachial artery could be correlated to the early stages of atherosclerosis development at the abdominal aorta. This can be detected by measured values of the systolic wall shear stress and elastic strain intensity which increases due to the forward pulse wave resulting from atherosclerosis, while the diastolic values of stresses decreases due to the delay of the backward waves which reach the brachial artery. The three scenarios of atherosclerosis show that the forward and backward waves, which can be attributed to changes in the diameter, length and thickness of the abdominal aorta, can be non-invasively used to diagnose cardiovascular diseases.

Common Bile Duct Dilatation

Summary: Cholestasis syndrome is accompanied by a large number of diverse liver and biliary tract diseases. Many cholestatic changes are fully reversible in the fi rst phase. However, with long-term cholestasis, extensive hepatocyte dysfunction occurs, the disease progresses, and many cholestatic syndromes result in irreversible liver damage and failure. Cholestatic liver diseases represent an important group of liver diseases that are an indication for liver transplantation. Postcholecystectomy syndrome is an imprecisely defi ned term, which includes a set of ongoing or recurrent or new diffi culties of patients after gallbladder surgery. We distinguish between early postcholecystectomy syndrome immediately in the postoperative period, or late postcholecystectomy syndrome, which occurs months or even years later. Ultrasonography is the fi rst imaging examination method for diseases of the liver and hepatobiliary system. It is a non-invasive method, available, relatively cheap, easily repeatable, and it does not represent a burden for the patient. Common bile duct dilatation after cholecystectomy is a common accidental fi nding that is inconclusive in the absence of clinical symptomatology and with normal laboratory fi ndings. Ursodeoxycholic acid forms the basis of cholestasis therapy, the only treatment whose effi cacy in cholestatic liver disease has been demonstrated in randomized and long-term studies. A further positive is that many years of ursodeoxycholic acid administration are not accompanied by more serious side eff ects. This case report supports the concept of a prompt and at the same time deepening benefi cial eff ect of ursodeoxycholic acid treatment in patients with cholestatic hepatopathy verified by ultrasonography indicated for conservative treatment or refusing invasive treatment. Key words: cholestasis – postcholecystectomy syndrome – ultrasonography – ursodeoxycholic acid

ABSTRACTMadelung’s disease is characterised by multiple symmetric abnormal fat masses in the head, neck and upper limbs. Surgical excision or liposuction is the only realistic available option, although palliative in nature. The serial intralipotherapy with phosphatidylcholine/deoxycholate has been proposed as a non-invasive treatment of Madelung’s disease. The authors used serial intralipotherapy with phosphatidylcholine/deoxycholate in two patients affected by Madelung’s disease. Three injections per lesion per patient were performed with 1 month’s interval. Pre- and 6 months’ post-treatment dimensions were assessed with ultrasound scan and patients were observed along a 5 years’ clinical follow-up. A 42.5% average size reduction was reported in all treated lesions. About 33% recurrence rate was observed in the 5 years’ follow-up. We confirm the efficacy of intralipotherapy in the non-invasive palliative treatment of Madelung’s disease, as a valid option to reduce the volume and limit the growth of the pathological adipose masses.

Lactate is known to be an indicator of neurological impairment during aortic aneurysm surgery. It is suggested that analysis of cerebrospinal fluid (CSF) removed during such surgery could provide useful information in this regard. Medical professionals find the prospect of online detection of such analytes exciting, as current practice is time consuming and leads to multiple invasive procedures. Advancing from the current laboratory based analysis techniques to online methods could provide the basis for improved treatment regimes, better quality of care, and enhanced resource efficiency within hospitals. Accordingly, this article considers the use of a low power microwave sensor to detect varying lactate concentrations. Microwave sensors provide a rapid non-invasive method of material analysis, which is robust, cost-effective, and has huge potential for a wide range of biomedical applications.

The work presents an efficient and non-invasive method to visualize the local concentration and viscosity distribution of two miscible and non-reacting substances with a significant viscosity difference in a microchannel with a Y-shape cell. The proof-of-concept setup consists of a near-infrared (NIR) camera and cost-effective dome lighting with NIR light-emitting diodes (LED) covering the wavelength range of 1050 to 1650 nm. Absorption differences of glycerol and water and their mixtures with a mass fraction of glycerol from 0 to 0.95 gGlycgtotal−1 were analyzed in the NIR spectral area. The resulting measurement images were converted in a concentration profile by using absorbance calculated with Lambert–Beer law. A linear behavior between the concentration and the absorption coefficient is demonstrated. The result of local concentration in mass fraction was used to determine the local viscosity and illustrated as distribution images. By variating the fluid parameters, the influences of the highly different original viscosities in the mixing procedure were investigated and visualized.

Silicone Prostheses

Background and aim: Facial defects (from neoplasms, trauma, etc.) can be functionally and emotionally devastating. A non-invasive treatment for these defects is the application of external prostheses. Conventionally, these prostheses are fabricated by an anaplastologist through a manual procedure, which is an expensive and time-consuming approach. Current advances in computational and engineering tools report an improvement in design and manufacturing of silicone prostheses. This demand motivated this study that aims to develop a methodology for fabricating customized nasal prostheses. Technique: In this study, an 80-year-old woman with a total defect of the nose is considered as case-study. The proposed methodology entails six tasks: (a) data acquisition, (b) three-dimensional reconstruction, (c) prosthesis design, (d) moulds fabrication, (e) prosthesis manufacturing and (f) final fittings. Discussion: The presented approach showed encouraging outcomes since it saves time, reduces costs and allows the achievement of prosthesis with the minimum contact and discomfort to the patient, disclosing excellent aesthetic and functional results. Clinical relevance Custom-made nasal prostheses with minimum contact and discomfort for the patient can be achieved using an engineering approach based on digital technologies and additive manufacturing that is cost-effective and less time-consuming than the manual procedure.

The evaluation of treatments such as embolization, stereotactic radiation, and even surgery would be enhanced by an objective method of measuring flow in feeding arteries or draining veins. We developed a non-invasive method of measuring vascular flow using cardiac gated phase contrast MR angiography (MR Q flow). The purpose of this work was to employ the same technique in a series of patients with vascular malformations of the head and neck. We selected a series of vascular malformations with simple arterial and venous architecture and significantly smaller vessel diameters than that encountered with Vein of Galen Malformations. Our aim was to determine the reproducibility of the derived flow values by using multiple velocity encoded sequences (VENC) and compare the values derived from the arterial feeders to the venous outflow data. There are inherent technical difficulties with assessing flow through multiple arterial feeders or draining veins, so the technique is most easily applied to AVMs with simple, easily defined feeding arteries or draining veins. Nonetheless, this technique is relatively straightforward to learn, rapid, cost-effective and may provide an objective means to assess therapeutic maneuvers when applied to head and neck vascular malformations.
