Fixator-assisted nailing of tibial fractures: New surgical technique and presentation of first 30 cases

Background

Intramedullary nailing is considered a “gold standard” for treatment of tibial shaft fractures. However, some types of fractures are typically considered as “difficult for nailing”. This group includes the periarticular fractures, fractures of both bones at the same level, comminuted and segmental fractures of the tibia. Fixator-assisted nailing (FAN) is an effective method treatment of these types of fractures. The main requirements for the ideal reduction device are an ease of its installation and an ability of multiplanar fracture reduction. Fixator-assisted nailing (FAN) with the use of two perpendicular to each other monolateral tubular frames perfectly meets these requirements. In this study we present this new surgical technique and the analysis of first 30 cases.

Solitary bronchioloalveolar carcinoma: CT criteria

The computed tomographic (CT) scans of 30 patients with solitary bronchioloalveolar carcinoma were reviewed. Common features at CT included the peripheral or subpleural location of a pulmonary mass (25 cases), pseudocavitation (18 cases), heterogeneous attenuation (17 cases), irregular margins forming a star pattern (22 cases), and pleural tags (21 cases). Using these CT criteria, four independent observers attempted to identify cases of bronchioloalveolar carcinoma from a larger sample of lung cancers and benign lesions by categorizing a series of test cases into four probability categories. Although the bronchioloalveolar carcinomas were correctly ranked in the two highest probability categories 75% of the time (in 45 of 60 cases), there was considerable overlap with other lung lesions, particularly with adenocarcinoma and large cell undifferentiated carcinoma. However, even though the typical features of bronchioloalveolar carcinoma are not invariable or highly specific, they are characteristic enough to suggest the diagnosis.     

Comparison of the results of provocation electrocardiographic tests with the questionnaire for detection of exertion-induced stenocardia (data of the epidemiological study)

The results of a combination of functional electrocardiographic tests were compared with those of a WHO questionnaire for angina of effort. Coronary disease was verified in 37% of patients with a double diagnosis of angina of effort, and in 100% of cases of angina of effort combined with ischemic electrocardiographic changes.     

Comparative evaluation of the anal sphincter function after sphincter-sparing operations in diffuse polyposis

Experience in treating 76 patients who were subjected to various sphincter-preserving operations is analysed. It is shown that after subtotal resection of the large intestine with ++abdomino-anal resection of the rectum and pull-through of the right parts of the colon into the anal canal as well as after pull-through of the segment of the transverse colon into the anal canal, the neuro-reflex activity of the musculus sphincter ani internus is destroyed in 55% and reduces in 25% of patients while the reflex activity of the musculus sphincter ani externus is disturbed in 45% of patients and is not restored later. The results bear evidence that the condition of the rectal obturation apparatus does not depend on the segment of the colon subjected to the pull-through operation (cecum, ascending colon, transverse colon). Experience has shown that the results of sphicterometry, electromyography, and electromanometry in various periods after colectomy, mucosectomy of the rectum, and formation of ileorectal anastomosis are much better than those after pull-through operations on various parts of the colon, and return to normal values in 18 months.
