Prefabrication of bone by vascular induction: an experimental study in rabbits.

The various methods of prefabricating flaps include vascular induction through staged transfer; pretransfer delay, expansion, and grafting; the use of alloplastic materials; and tissue bioengineering. In this experimental study, vascular induction was used to provide an axial vascular pedicle to randomly nourished tissue. Twenty-six New Zealand rabbits, ages and weights ranging between 6 months-1 year and 1.5-3.5 kg, respectively, were used. The sex difference was not considered. The deep inferior epigastric artery and vein were used to carry blood and were placed into a segment of femur to prefabricate the bone. Four weeks later, the viability of the segment of bone prefabricated by new axial pedicle was shown by scintigraphic study, and the new axial pedicle was ready for free transfer.     

Lidocaine 10% in the endotracheal tube cuff: blood concentrations, haemodynamic and clinical effects

The purpose of this study was to evaluate the effects (common haemodynamic variables, peak cuff pressures, the incidence of reaction ('bucking') during extubation and the incidence of sore throat after operation) of lidocaine 10% instilled into the endotracheal tube cuff in intubated patients. Plasma concentrations of lidocaine were assayed. Seventy ASA class I-II patients scheduled for plastic surgery were studied. Patients were randomly divided in two groups: the cuff of the endotracheal tube was inflated with either lidocaine 10% (group L) or with saline (group S) immediately after endotracheal intubation. In group L patients, the haemodynamic changes were less (P < 0.05), and the peak cuff pressure was lower (P < 0.01) than for group S. At extubation, more patients reacted ('bucked') in group S (70.5% vs. 19.4%, P < 0.01). The incidence and severity of sore throat were significantly lower in group L 1 and 24-h after extubation. Plasma lidocaine concentrations did not reach toxic values. Lidocaine 10%, compared with saline, in the endotracheal tube cuff was associated with less disturbance of haemodynamic responses and less incidence of bucking during tracheal extubation. Lidocaine was also effective in reducing of incidence and severity of sore throat after operation.     

Surgical treatment of pulmonary hydatid cysts in children

OBJECTIVE: Hydatid disease is a parasitosis and endemic in many sheepraising areas; it is still an important health problem in Turkey. We report our experience with childhood hydatid cyst and discuss the concepts of treatment. METHODS: The clinical courses of 128 children with thoracic and liver hydatid cyst operated on from 1994 to 2000 were reviewed. The group consisted of 71 boys and 57 girls aged from 8 months to 16 years. Intact cysts were found in 144 patients and ruptured cysts in 68. RESULTS: In the postoperative course we have encountered 20 perioperative complications in 16 patients. The most common complication was residual pleural space and delayed air leakage, which occurred in 9 patients. There was no early death. CONCLUSION: Surgery is the treatment of choice for most patients with pulmonary hydatid disease. The aim of surgery is evacuation of the cyst, removal of the endocyst, and management of the residual cavity. Conservative surgical methods that preserve lung parenchyma should be preferred.     

Impact of tubal sterilization on women's health

In this study we aimed to investigate the possible health effects of tubal sterilization on women who had chosen this method. A total of 127 women who had tubal sterilization between 2000-2005 were asked about their satisfaction with the method; their regrets and complaints, the effects of the tubal sterilization on their sexual life and their actual health. While 95% of the women were satisfied with the operation, only 76.9% of the patients would recommend this method to other woman. Although 23.1% reported changes in their sexual life after the sterilization, 30% reported changes in their menstrual cycle and 35% reported lower abdominal pain, two-thirds of the women did not state any significant complaint. Women who underwent the procedure at least two years before had fewer complaints; high school graduates and more educated women reported more changes in their sexual life. Women who had tubal sterilization were mostly satisfied with the method and were willing to recommend it to another woman.     

Feasibility of breast conserving surgery in multifocal breast cancers

Background

Multifocal breast cancers (MFBCs) present a challenge to surgeons. Although its feasibility is still controversial, breast-conserving surgery (BCS) is not contraindicated for MFBCs. The investigators retrospectively evaluated the feasibility of BCS and reviewed histopathologic findings in patients with MFBC.

Methods

A total of 222 patients with MFBC who were treated with either BCS (119 patients) or mastectomy (103 patients) at a single institution between January 2002 and December 2011 were retrospectively evaluated.

Results

The median follow-up time was 55 months (range, 10 to 102 months). Lymphovascular invasion and lymph node involvement were significantly less frequent in the BCS group (48.8% vs 62.2% for lymphovascular invasion, P = .04; 52.1% vs 71.8% for lymph node involvement, P = .002). There were no differences in local recurrence rates between the 2 groups. The overall survival rates were 92% in the BCS group and 72% in the mastectomy group (P = .000).

Conclusions

BCS is a feasible and safe procedure for the removal of multifocal tumors. Extended lymphovascular invasion is associated with mortality in patients who undergo mastectomy.     

Collar-type osteophyte of the femur in young adults: is it a harbinger of intra-articular osteoid osteoma?

Variable clinical and radiological findings for intra-articular osteoid osteoma (OO) of the hip joint make its diagnosis difficult. Because radiographs commonly do not identify the nidus, MR imaging becomes the second line of study. However, because the appearance varies, findings on MR images can be confusing. We found “collar type osteophyte” of the femur i.e. an osteophyte rim around the femoral neck, to be a conspicuous finding of intra-articular OO. Here, this feature will be emphasized and intra-articular OOs will be discussed, with a review of the literature.     

Gastrointestinal motility in the elderly]

The existence of specific, age-related changes in gastrointestinal motility with clinical significance is controversial. Beside the more infrequent primary motility disorders, secondary motility disturbances associated with collagen vascular diseases, endocrinopathies, and neuromuscular diseases are prominent in the older and often multimorbid patients. Especially in geriatric patients, motility associated symptoms are undesired side-effects of drug therapy. The pathophysiology, clinical syndromes, and therapeutic principles of motility disorders in the elderly are discussed. The major symptoms of esophageal dysfunction are dysphagia, chest pain, heartburn, and regurgitation. Oropharyngeal dysphagia, mostly caused by cerebrovascular accidents and other neurologic disorders, leads to disturbances in food intake, and is often complicated by broncho-pulmonary infections arising from recurrent aspiration of food or saliva. Gastrointestinal reflux disease and spastic motility disorders of the esophagus are regarded as possible causes of angina-like chest pain after exclusion of cardiac diseases. Motility disturbances of the stomach and small bowel are often related to systemic disease (i.e., diabetes mellitus, chronic intestinal pseudo-obstruction) of drug side-effects. Mental and physical decline, reduced fluid intake, and constipating drugs are the most relevant factors for idiopathic constipation in the elderly. Fecal incontinence means a great psychological strain for older patients and leads to social isolation.     

Annular pancreas--a congenital abnormality of the pancreas

Our case report on a 26-year-old male suffering from epigastric pain for several years should emphasize the fact, that even a rare congenital malformation like the annular pancreas must seriously discussed as a reason for the so called unspecific abdominal pain. Embryological development, age of manifestation, symptoms and therapeutic concepts are described. The importance of endoscopic methods such as gastroduodenal endoscopy and endoscopic retrograde cholangiopancreatography (ERCP) for a more precise and frequent diagnosis will be strengthened and the influence on the prevalence will be discussed.
