In recent years, at the Hospital Surgical Clinic of Kazan University, there have been several rather interesting cases of replacement of extensive defects of the skull after traumatic injuries, accompanied by epileptic seizures.

The Difference

Object Hemicraniectomy is a commonly practiced neurosurgical intervention with a wide range of indications and clinical data supporting its use. The extensive use of this procedure directly results in more cranioplasties to repair skull defects. The complication rate for cranial repair after craniectomy seems to be higher than that of the typical elective craniotomy. This finding prompted the authors to review their experience with patients undergoing cranial repair. Methods The authors performed a retrospective review of 212 patients who underwent cranial repair over a 13-year period at their institution. A database tracking age, presenting diagnosis, side of surgery, length of time before cranial repair, bone graft material used, presence of a ventricular shunt, presence of a postoperative drain, and complications was created and analyzed. Results The overall complication rate was 16.4% (35 of 213 patients). Patients 0–39 years of age had the lowest complication rate of 8% (p = 0.028). For patients 40–59 years of age and older than 60, complication rates were 20 and 26%, respectively. Patients who originally presented with traumatic injuries had a lower rate of complications than those who did not (10 vs 20%; p = 0.049). Conversely, patients who presented with tumors had a higher complication rate than those without (38 vs 15%; p = 0.027). Patients who received autologous bone graft placement had a statistically significant lower risk of postoperative infection (4.6 vs 18.4%; p = 0.002). Patients who underwent cranioplasty with a 0–3 month interval between operations had a complication rate of 9%, 3–6 months 18.8%, and > 6 months 26%. Pairwise comparisons showed that the difference between the 0–3 month interval and the > 6-month interval was significant (p = 0.007). The difference between the 0–3 month interval and the 4–6 month interval showed a trend (p = 0.07). No difference was detected between the 4–6 month interval and > 6-month interval (p = 0.35). Conclusions The overall rate of complications related to cranioplasty after craniectomy is not negligible, and certain factors may be associated with increased risk. Therefore, when evaluating the need to perform a large decompressive craniectomy, the surgeon should also be aware that the patient is not only subject to the risks of the initial operation, but also the risks of subsequent cranioplasty.

The article reviews main stages of establishment and development of the Department of Hospital Surgery in different periods. We showed the role of heads and stuff of the department in the development of multipartial complex which aims at the unity of three components – to teach, to treat and to study.The first head of the department and of the clinic of hospital surgery (1921–1931) was N.A.Sinakevich. It was a pe-riod of establishment of the department, its staffing, formation of clinical site and training calendar. V.G.Shipachyov was the head of the department from 1931 to 1952. During the Great Patriotic War, the work of the department was aimed at the needs of war time related to the problems of reconstruction surgery and treatment of traumatic injuries. After the war, the work of the department was dedicated to the problems of hypothyroidism, obliterating endarteritis, gastrointestinal and urgent surgery.In 1953, Z.T.Senchillo-Yaverbaum became the head of the department. The work of the department was dedicated to gastrointestinal and pancreatic surgery, herniology, thyrophymas. Also the department included course of traumatology.In 1972, V.I.Astafiev became the head of the department. In this period, many young hopefuls started to work on the department. Also the research, treatment and educational complex was created on the base of the department, Re-gional Clinical Hospital and Siberian Branch of Academy of Medical Sciences USSR. While keeping the traditions of the department, V.I.Astafiev created new research and practice directions and special referral units – of cardiac, vascular, thoracic, purulent and urgent surgery, operative coloproctology, plastic surgery, diagnostic picture and X-ray surgery. Also the system of individual and collective training of surgical clerk.In 1988–1993 Y.I.Morozov was the head of the department. The new direction of the work was the development of complex treatment of purulent soft tissue involvement in patients with diabetes.From 1993, E.G. Grigoryev is the head of the department of hospital surgery and the Institute of Surgery.

The Brain

Over 20 years ago, Watt and Hameroff (1987 ) suggested that consciousness may be described as a manifestation of deterministic chaos in the brain/mind. To analyze EEG-signal complexity, we used Higuchi’s fractal dimension in time domain and symbolic analysis methods. Our results of analysis of EEG-signals under anesthesia, during physiological sleep, and during epileptic seizures lead to a conclusion similar to that of Watt and Hameroff: Brain activity, measured by complexity of the EEG-signal, diminishes (becomes less chaotic) when consciousness is being “switched off”. So, consciousness may be described as a manifestation of deterministic chaos in the brain/mind.
