The chapter discusses the importance of early diagnosis in tuberculosis (TB) and the effectiveness of sanatorium treatment. Key indicators of early TB include increased pulse rate, gradual weight loss, digestive disturbances, presence of tubercle bacilli in sputum, "vesiculo-bronchial" breathing, and small crepitant rales. The shape of the chest, while often considered normal in TB patients, may be round instead of flat. The tuberculin test is unreliable, and family history and personal environment are crucial factors. Prophylaxis and public health measures, such as disinfection, improved sanitation, and education, are emphasized to prevent the spread of TB. The use of X-rays in diagnosing and treating TB is highlighted, with reports showing their effectiveness in detecting and monitoring the progress of the disease. High-frequency currents and specific electrodes are also discussed as effective treatments for various conditions, including cancer and lupus. The chapter concludes with a critical examination of the potential side effects and limitations of X-ray therapy.The chapter discusses the importance of early diagnosis in tuberculosis (TB) and the effectiveness of sanatorium treatment.
