Objective. This study was designed to observe the histocompatibility and long-term results of wigs after xenogeneic hair transplantation and to explore the possibility of industrial products in clinical application. Methods. The human hair and melted medical polypropylene were preceded into the follicular unit-like wigs according to the natural follicular unit by extrusion molding. 12 New Zealand rabbits were used as experimental animals for wigs transplantation. The histocompatibility of polypropylene and human hair was observed by H&E staining and scanning electron microscope. The loss rate of wigs was calculated to evaluate the long-term result after transplantation. Results. Mild infiltration by inflammatory cells around the polypropylene and human hair were seen during the early period after transplantation, accompanied with local epithelial cell proliferation. The inflammatory cells were decreased after 30 days with increased collagen fibers around the polypropylene and human hair. The follicular unit-like wigs maintained a good histocompatibility in one year. The degradation of hair was not significant. The loss rate of wigs was 4.1±4.0% in one year. The appearance of hair was satisfactory. Conclusions. We successfully developed a follicular unit-like wigs, which were made of xenogeneic human hair with medical polypropylene, showing a good histocompatibility, a low loss rate, and satisfactory appearance in a year after transplantation. The follicular unit-like wigs may have prospective industrial products in clinical application.

Localized Stenosis

We report the results of percutaneous transluminal coronary rotational atherectomy (PTCRA) for localized stenosis caused by Kawasaki disease (KD). Thirteen male and a female, aged 5 to 29 years (median 13 years), underwent PTCRA and the interval from the PTARA to the latest angiogram ranged from 3 months to 16 years (median 6 years). The target vessels were the left anterior descending artery (3 patients), the left circumflex (2), left main trunk (2) and the right coronary artery (7). The immediate results of PTCRA were successful in all patients, and the mean stenosis degree improved from 86 ± 11% to 36 ± 13%. Five cardiac events occurred within one year (acute myocardial infarction 2, transient complete atrioventricular block 1 and re-PTCRA 2). The survival rate and cardiac event free rate at 15 years after PTCRA were 93% and 71%, respectively. For the graft patency, 4 pts who underwent PTCRA within 10 yeas old, had asymptomatic occlusion within 1 year. The patency rate at 15 years after PTCRA was 69%, in 10 pts who underwent it more than 10 years old. Cardiac events and restenosis occurred within a year after PTCRA. The results in patients less than 10 years old was poor. If a graft is patent in one year after procedure, long-term patency may be expected in patients more than 10 years old.

Aim. To assess the results of distal pancreatectomy for malignant and benign tumors and chronic pancreatitis complications. Materials and methods. Forty-seven patients, who underwent distal pancreatectomy, were under observation during the period from 01.01.2008 to 28.02.2019. Results. The long-term results of surgical treatment demonstrated the following complications: pancreatic fistulas – 15 % of observations, pancreatogenic diabetes mellitus – 12.7 %, subphrenic abscesses – 10 %. In the long-term period after the surgery – from 10 years and not less than one year – 30 patients were followed up, constituting 63.8 % of the total number. Conclusions. To prevent complications in the form of pancreatic fistula with pathological Wirsung duct dilatation more than 4–5 mm in diameter, it is necessary to form anastomosis between the pancreatic stump and the small bowel.

Introduction. The aim of this study is to evaluate the outcome of introduction of early surgery in the course of isolated ileocecal Crohn’s disease, where there is no absolute indication of surgery. Methods. Observational study involving patients with isolated ileocecal Crohn’s disease who underwent early surgical resection (within one year of the presentation of the hospital). A complete blood count, ESR, and CRP were done and compared between the preoperative value, 1st postoperative visit (3-4 weeks), and last follow-up visit. Statistical analysis was done using Analysis of Variance (ANOVA) to compare the different figures. Results. There was a statistically significant increase in the hemoglobin levels between preoperative, postoperative, and long-term follow-up and a significant decrease in leukocyte count between the pre- and postoperative values (F=19.8, p<0.001 and F=8.9, p=0.002, resp.). Similarly, the ESR and CRP values were decreased significantly at long-term follow-up (F=8.5, p=0.019 and F=8.3, p=0.013, resp.). Conclusion. Early surgical resection in isolated ileocaecal Crohn’s disease achieved significant biochemical improvements. These successful results in this small number of patients indicate that early surgical intervention may provide better outcomes. These initial results encourage larger and comparative studies of long-term results versus long-term use of biological agents.

Early and long-term results of radiofrequency facet destruction for 245 patients with cervical, thoracic and lumbar spondyloarthrosis were presented. One hundred six patients (control group) were treated conservatively. Treatment results were assessed by pain syndrome intensity using pain audit. One year after operation good result was observed in 62 (32%) out of 195 patients and satisfactory results — in 117 (60%) patients. That method enabled to eliminate considerably vertebrogenic pain localized in one dermatome when conservative treatment failed. Our experience showed that radiofrequency facet nerves destruction was safe and did not result in soft tissue injuries. All that enabled patients to return to work at maximum short terms.

AbstractOur pilot study reports twenty-six cases of resolved chronic otitis media in which the human, cadaveric styloid process was used as an ossicular graft material. A maximum follow-up of one year is presented in this paper. There was no extrusion or rejection of the styloid processes. Hearing improvement with a closure of the air-bone gap to within 10–15 dB. of the pre-operative bone conduction was found in most cases. So far the styloid process has proved to be an ideal ossicular graft though the long-term results are yet to be seen.

L1 Acquisition

It has been proposed (Krashen, 1981; 1982; 1985; Schwartz and Gubala- Ryzak, 1992; Schwartz, 1986; 1988; 1993) that L2 acquisition proceeds in essentially the same manner as L1 acquisition (the L1 = L2 position). That is, learners acquire underlying unconscious knowledge of a language (called lin guistic competence) simply by being exposed to the linguistic input (called primary linguistic data) in the environment. Instruction and error correction play no role in the development of competence in the L2. This article reports the long-term results of a study investigating the role of primary linguistic data in the acquisition of linguistic competence - in par ticular, the rules of adverb placement in English. This study examines the knowledge of adverb placement of 52 grade-6 francophone students (aver age age: 12 years, 2 months) learning English as a second language (ESL) in Québec schools. A year earlier, these subjects had been exposed over a two- week period to a flood of primary linguistic data on adverb placement in English. Immediately after the input flood, it was found that while the sub jects had learnt which adverb positions were grammatical in English, they still used positions which were ungrammatical in English but grammatical in the L1. The results of the follow-up test reported in this article reveal that one year after the input flood, the subjects' knowledge of adverb placement has not changed. They still use both the grammatical and the ungrammatical adverb positions, indicating that exposure to an abundance of primary lin guistic data on adverb placement did not lead to mastery of this structure. Possible explanations for these results and their implications for the L1 = L2 position are discussed.

Background Pelvic venous reflux is known to be associated with lower limb varicose veins in 20% of women with a history of at least one previous vaginal delivery. Pelvic vein embolisation with coils has been shown to be a successful treatment in the short term. The objective of this study was to ascertain the long-term outcomes of pelvic vein embolisation for pelvic venous reflux. Methods Patients who had undergone pelvic vein embolisation in 2005–2007 were invited back to a specialist vein unit for transvaginal duplex ultrasonography in the summer of 2013. A total of 110 women were contacted. Pre-embolisation transvaginal duplex ultrasonography results were compared to those obtained six weeks post-procedure and at long-term follow-up. Results Twenty-eight female patients aged 40 to 75 years (mean 53.5) attended (response rate 25.5%), with parity prior to embolisation ranging from 1–5 children (mean 2.8). Mean follow-up time was 7.5 years. Six weeks post-procedure, 25 women had complete or virtual elimination of all reflux, and three had persistent reflux in at least one vein. At long-term follow-up, 11 women had complete elimination of all reflux, seven had elimination of all truncal reflux but minor reflux in vulval veins, six had minor reflux in one truncal vein, and four had significant reflux in one or more truncal veins (one of these gave birth one-year post-pelvic vein embolisation and another had coils removed during gynaecological surgery). Conclusions Transjugular pelvic vein embolisation is a durable technique for the abolition of reflux in the pelvic veins and is particularly adept at treating reflux in the ovarian veins.

Aim. To assess the immediate and long-term results of treating patients with bilateral lung cancer (LC). Patients and methods. Radically operated 5 patients with primary multiple synchronous LC (PMSLC) and 5 patients with primary multiple metachronous LC (PMMLC) were included in the study. Clinical and morphological data, results of instrumental studies, immediate and long-term treatment results were analyzed. Statistical analysis was performed using the Statistica6 software. Results. Tumors corresponding to T1‑T2 prevailed in both groups. At the same time, both in the PMSLC and PMMLC group, only in one case both tumors corresponded to T1–2N0M0, in the others — one or both tumors were with metastases in lymph nodes of the root or mediastinum. In early postoperative period, the number of surgical complications was 10%, somatic — 20%. All complications were successfully treated conservatively. Postoperative mortality was not observed. In PMMLC and PMSLC cases, one-year relapse-free survival (RFS) was 100% and 80%; two-year — 80% and 60%; three-year — 60% and 60%; four-year — 60% and 20%, respectively. The five-year RFS in patients with PMMPC was 40%. One patient with PMSLC was alive without relapse of disease for 4.5 years. Accordingly, one-year overall survival (OS) was 100% and 100%; two-year — 80% and 80%; three-year — 80% and 60%; four-year — 80% and 40%. Five- and six-year OS in patients with PMMLC were 60% and 20%, respectively. Conclusion. The absence of postoperative mortality and low number of postoperative complications indicate the safety of bilateral operations in patients with bilateral LC. Low rates of patients’ 5‑year survival are connected with problems of primary diagnostics and low efficiency of existing algorithms of regular medical checkup of patients with this pathology. To improve long-term results of LC treatment, it is necessary to more actively introduce the modern programs of dynamic observation and complex examination of patients, undergone surgery for LC, using the annual chest CT and fibrobronchoscopy.
