AbstractObjectiveOur aim was to assess the immediate and short term results of closure of moderate and large patent arterial ducts using the self-expanding and repositionable Amplatzer device.MethodWe attempted closure in 25 patients (10 Females and 15 males) using the Amplatzer occluder. Their median age was 48 months with a range from 8months to 26years and median weight of 14kg with a range from 4.5kg to 48kg. The mean ductal diameter was 4 (S.D 1.51mm). A 6F/7F long sheath was used to deliver the device. Follow up was performed with colour- flow mapping of the pulmonary trunk within 24 hours, at 3 months, and 6 months of closure.ResultsOf the 25 patients, the device was placed successfully in 23. Concurrent angiography showed immediate closure in 12 patients, while 8 had trivial shunting and 3 had mild shunting. Within 24 hours, Doppler examination revealed complete closure in all but three patients, who had a mild residual shunt. Two attempts were unsuccessful. Both these patients underwent successful surgical ligation. All except one patient were discharged on the next day. Of the 23 patients, 15 (65%) have been followed up for 3months, while 8 (35%) have completed 6 months of follow-up. Of the three patients initially with mild residual flow, two had completely closed at 3 months The one remaining patient is yet to be seen at the 3 month follow-up. Thus, at 3 months, all patients studies had shown complete closure.ConclusionAntegrade transcatheter closure using the Amplatzer duct occluder is an efficacious treatment for bigger patent arterial ducts. Long-term follow-up is necessary to show sustained benefits and confirm the absence of side effects.

AbstractFrom a cohort of 35 patients with hereditary haemorrhagic telangiectasia (HHT), 12 patients have undergone closure of the one or both nasal cavities during the last three years for refractory epistaxis. All had failed other forms of treatment including hormone therapy, laser coagulation and septodermoplasty. All patients were available for follow-up at six months or longer. In all patients where complete closure was achieved (11 out of 12) bleeding ceased completely from the operated side.

Implant Therapy

Introduction: The interpretation of clinical results of dental implant supported prosthesis treatment is very crucial to be able to make a comparison between different implant systems and treatment options and furthermore to benefit the experiences of the other clinicians. However, the clinical outcomes of these studies should be reported in an objective way and be independent from the system used and also be prepared in accordance with certain criteria and standards that have been accepted scientifically world-wide for being reliable and describing long-term results. Aim: Three-hundred and eighty-two consecutive NTA implants were performed on ninety-nine patients. The implants used in 2016 and the constructed restorations were retrospectively analyzed. In addition, the effect of the experience of clinician was evaluated related with the success of the implant therapy. Materials and Method: This retrospective study was conducted in the Department of Prosthodontics Süleyman Demirel University. Three-hundred and eighty-two consecutive NTA implants were performed on ninety-nine patients. The implants used in 2016 and the constructed restorations were retrospectively analyzed. Results: The implants were followed for at least 2 years. In total, 239 implants were inserted. It was found in 143 mandibles. Prosthetic restorations were determined to be partial prosthetics (219), single crown (81) and overdenture prosthetics (64). During the evaluation period, 6 implants failed before prosthetic treatment, ten decementations, six retentive screw loosening and five porcelain chipping were detected. Discussion and Conclusions: The early results of our study are consistent with the results of other studies. However, long-term follow-up is required for more accurate assessments.

AbstractTo judge whether an Amplatzer™ Septal Occluder can be used as standard therapy instead of surgery for closure of atrial septal defects we report our experiences in 200 patients. Of these patients, 127 had an atrial septal defect with haemodynamically significant left-to-right shunt, 68 patients a persistent oval foramen after presumed paradoxical embolism, and 5 had a fenestration after Fontan-repair. Mean age was 29.8 years (0.8 to 77.7 years). Body weight ranged from 6.9 to 120.0 kg (mean 51.5 kg). After diagnostic cardiac catheterization, and balloon-sizing of the defect, we implanted Amplatzer™ Septal Occluders with stents of 4 to 28 mm diameter. Follow-up studies were obtained after 48hours, and one, six, and twelve months. Transcatheter closure of the atrial septal defect proved successful in all without any relevant residual shunts. In particular, complete closure was achieved in all patients after presumed paradoxical embolism. The mean period of follow-up is 9–5 months, with a range from 0.4 to 23.5 months, giving a total of 1898 patient months. The occlusion rate after three month was 98.1°. A trivial haemodynamically insignificant residual shunt remained in 1.9° of the patients. Fluoroscopy times ranged from 0 to 43.5 minutes, with a median of 8.7 minutes. The excellent results in the short and medium term in children and adults have resulted in using this device routinely at the present time for closure of central atrial septal defects up to a diameter of 28 mm. Final judgement, however, is only possible after long-term follow-up.

A number of studies over the last decade have reported on a viability of the primary neoglottis reconstruction after total laryngectomy. Early results have been encouraging, although operative and perioperative complications are higher than with a classic laryngectomy. This article reports on a series of 13 neoglottis reconstructions performed at Emory University Medical School using the techniques developed by Mario Staffiert, MD. During the course of the study, the overall success rate has fallen from 80% at three years to 54% at five years. With each succeeding year there has been an increasing need for revision surgery. The series emphasizes the need for long-term follow-up in any vocal rehabilitation procedure.

Neurofibrosarcoma is a malignancy that occurs more frequently in patients with neurofibromatosis- 1 (NF- 1) and rarely may arise independently. This is a presentation of 3 consecutive patients with histologic diagnosis of neurofibrosarcoma who presented to the University of Calabar Teaching Hospital, Calabar from 2011-2013. Two patients presented were associated with NF-1 and were a decade younger than the one without NF-1. Late presentation and poor follow up were notable underlying factors. Long term follow up of patients with NF -1 for early diagnosis and adequate treatment will improve outcome.

Breast Sensation

This study has quantitatively measured breast sensation following reduction mammaplasty using a vertical bipedicle technique. Breast sensation was quantitatively assessed by determining pressure and vibratory threshold values preoperatively in 20 subjects, and postoperatively in 15 patients. The nipple, areola and breast body were all independently assessed. Early results, less than one month postoperatively, revealed significant reductions in vibratory and pressure thresholds in the nipple and areola. Long term follow-up revealed that breast sensation returned to normal using this surgical technique.

✓ The authors report the results of a long-term follow-up study of the effects of the physiologically defined selective VIM (nucleus ventralis intermedius)-thalamotomy on tremor of Parkinson's disease in 27 patients and essential tremor in 16 patients. The follow-up period ranged from 3.25 to 10 years (mean 6.58 years). In 43 patients a total of 50 operations (including four bilateral operations and three reoperations) were carried out. The early (2 to 4 weeks after surgery) and late effects on the tremors were determined clinically and electromyographically. Fourteen parkinsonian cases were treated with minimal lesions (about 40 cu mm). Their late results were very similar to the early results: in 10, the tremors were completely abolished, three had a slight residual tremor, and one underwent reoperation 3 months after the first surgery. Eleven essential tremor cases were treated with minimal lesions. Six of these tremors were completely abolished, four patients had slight residual tremors, and one patient with a recurrence underwent reoperation 2 years after the initial surgery. In these 23 successful operations with minimal lesions (excluding two cases with reoperation), the tremor was abolished without discernible long-lasting side effects. The other 23 operations on 16 patients with Parkinson's disease (including one reoperation) and on seven with essential tremor (one of whom also had a minimal lesion on the other side) involved relatively large lesions. In this group, the surgery was successful in almost every case. It was concluded that radiographically and physiologically monitored selective VIM-thalamotomy for parkinsonian and essential tremor is effective even when lesioning is minimal. Moreover, the beneficial effect is maintained over a long period of time.

Adenomatous Tissue

ABSTRACT Transsphenoidal surgery is an efficacious treatment for patients with prolactin (PRL)-secreting adenomas, even if disrupted pituitary-hypothalamic relationships may persist and/or a recurrence of the PRL-secreting tumor can occur. In this paper, we analyze the long-term follow-up of 119 consecutively treated women who underwent transsphenoidal microsurgery for PRL-secreting adenomas. Apparent total removal of the tumor was achieved in 98 patients who had enclosed tumors (58 with Grade-I tumors and 40 with Grade II). In the remaining patients, the removal was considered partial. Persistent normal basal PRL levels were achieved in 61 patients who had apparent total removal of the adenoma (44 with Grade I tumors and 17 with Grade II). Of the remaining 37 patients in whom surgical removal of the adenomatous tissue was thought to be total, 30 had persistent nonevolutive, high PRL levels ranging from 21 to 196 ng/ml, without clinical and radiological signs of tumor regrowth, and 7 with PRL levels ranging from 56 to 560 ng/ml had a recurrence of the PRL-secreting tumor. These data seem to indicate that a slightly elevated postsurgical PRL value does not imply that tumoral tissue is still present. Nontumoral conditions (i.e., a secondary empty sella) could induce functional hyperprolactinemia.

Twenty-two patients with a diagnosis of scapholunate instability underwent a modified Brunelli procedure. The overall results of this short follow-up study showed that a majority of patients (17 out of 22) had relief of pain. Grip strength recovered well. Postoperative range of motion was reduced in extension and flexion, remained unchanged for radial deviation and improved for ulnar deviation. The radiological appearance of dynamic or static scapholunate instability did not change after the procedure. Most patients (17 out of 22) felt subjective improvement and would have the operation again. A significantly poorer result was seen in those patients with an unresolved medicolegal claim. Although short-term results are encouraging for some patients, the authors feel that more long-term follow-up is needed before recommending the procedure.
