Management of breast cancer

Breast cancer is the most frequently diagnosed life-threatening cancer in women and the leading cause of cancer death among them worldwide. It includes a heterogeneous collection of diseases with various histologically defined subsets, clinical presentations, responses to treatment and outcomes. We describe a case of female patient with ductal breast carcinoma.

Total atelectasis of the right lung due to bronchogenic carcinoma

Despite the emerging developments in the diagnosis and treatment of lung cancer in recent years, it is still the most lethal among all cancers. Atelectasis is a common condition with lung cancer. Central bronchogenic tumors often induce atelectasis due to endobronchial obstruction but less frequently due to compression of tumor or pleural effusion. The presented case describes case of a patient, who was repeatedly admitted to the Department of Pneumology and Phtiseology due to bronchogenic carcinoma with the future release of it´s complications including obstructive atelectasis of the right lung.

Cardiac tamponade due to cardiac metastases

Cardiac tamponade is a clinical syndrome caused by the accumulation of fluid or gas in the pericardial space, resulting in reduced ventricular filling and therefore decreased cardiac output (Figure 1). The condition is a medical emergency with resultant cardiogenic shock and death if not treated immediately. The presented case report describes a 63-year-old oncological patient who developed cardiac tamponade with the need of pericardiocentesis.

The Use of the Er:YAG Laser 2940 nm in complex caries removal

Significant pain reduction and lack of the vibrations give advantage to LASER cavity preparation. The ideal treatment should be fast, painless and effective. Discomfort of the patient and tendency to protect hard dental tissues can lead to insufficient debridement of the carious lesion, inadequate obturation and failure of the restoration. A carious lesion is usually removed using hand instruments and rotary burs.
Understanding of laser physics and laser-tissues interaction for specific wavelength is required to predict the accomplishment of laser treatment.

Femtosecond laser in cataract surgery

Femtosecond laser uses an infrared beam of light to precisely separate tissue through a process called photodisruption by generating pulses as short as one-quadrillionth of a second. It has wavelength of 1053 nm and is based on the technology whereby focused laser pulses divide material at the molecular level without transfer of heat or impact to the surrounding tissue.
