Abstract Integrated power devices (IPD, IC+MOSFETs) have gained popularity for their excellent power management performance and compact size. During the development, it was soon found that exposing the multi-die device for debug could be challenging. In the article, we will show how the traditional decapsulation method fails to expose the device properly for follow up analysis. We will then present a new technique using laser ablation + chemical/plasma etch that proves to work for IPD products. We will then present a complete FA example combining this decapsulation technique and many other advanced FA techniques to solve an elusive failure during the development phase of an IPD product.

Ingrown Toenails

Background: Severely incurved toenails are accompanied by deformity of the toenail growth plate. In such a condition, partial removal of the nail and nail bed and simple unfolding of the nail itself frequently result in the recurrence of symptoms. We sought to design and develop a new technique for the treatment of incurved toenail with growth plate deformity and to report the results of treating this disease entity. Methods: Forty consecutive patients (52 cases) underwent treatment of symptomatic incurved toenails with a new technique named matrixplasty. The mean ± SD patient age was 40.3 ± 18.9 years. Last follow-up was at a mean ± SD of 18.0 ± 1.3 months. An American Orthopedic Foot and Ankle Society (AOFAS) forefoot hallux score was assigned, and patients were evaluated before treatment and at last follow-up. Patient satisfaction and the recurrence rate of the deformity were evaluated. For evaluation of improvement in toenail shape, the center to edge angle of the toenail was measured before treatment and at last follow-up. The complication rate was also evaluated. Results: All of the ingrown toenails healed, and the nail deformities were corrected within 3 weeks after the procedure. None of the incurved toenails had recurred by last follow-up. The mean pretreatment AOFAS forefoot hallux score was 72.9, and it improved to 99.6 by last follow-up (P < .001). Every patient was very satisfied or satisfied with the results of treatment. The mean ± SD center to edge angle of the toenail improved from 53.3° ± 9.5° to 15.3° ± 5.2° by last follow-up (P < .001). Minor paronychia, which was managed with local wound dressing and oral antibiotics, was identified in four cases. No other complication was identified. Conclusions: Matrixplasty showed excellent clinical results in the treatment of severe incurved toenail, and this newly developed procedure showed improvement of the deformed toenail and its growth plate.

A New Technique

AbstractIntroduction:Cerebrospinal fluid rhinorrhoea is the abnormal leakage of cerebrospinal fluid into the nasal cavity. The posterior wall of the frontal sinus can be the site of such leakage. Traditionally, these leaks were repaired via external osteoplastic or neurosurgical approaches. Despite advances in instrumentation, it is difficult to manage superiorly or laterally placed defects endoscopically. We present a new technique of endoscopic repair of frontal sinus posterior wall defects, via access holes drilled in the anterior wall of the frontal sinus.Study design:Preliminary study involving patients presenting with frontal sinus cerebrospinal fluid leaks, with defects in the frontal sinus posterior wall, between 2006 and 2010.Setting:Patients were treated in a tertiary referral centre for nose and sinus diseases. Patient records were reviewed and analysed.Results:Nine patients underwent external frontal sinusotomy under endoscopic vision. Repair was successful in all cases, with no complications. Follow up ranged from three months to three years.Conclusion:External frontal sinusotomy and endoscopic repair is a simple, precise and cosmetically acceptable alternative to osteoplastic and major neurosurgical techniques for management of frontal sinus posterior wall defects. This new, previously undescribed technique enables otolaryngologists to play a role in managing such defects.

We present the outcomes of the delayed management of eight displaced intra-articular fractures of the metacarpal and phalangeal heads treated with capsuloligamentotaxis using the Penning mini-external fixator. Closed anatomical reduction with a 2 mm over-distraction was achieved at the time of operation at an average of 20 days after the initial injury. Excellent outcomes in terms of function and pain were obtained at 6 month’s follow-up in all cases. This technique is simple, minimally invasive, and effective, with minimal complications.

Pain Symptoms

To obtain a better active contention of the lumbosacral spine, a new technique of liposuction of the fat surrounding the atrophied paraspinal muscles is described. A preliminary series of 40 patients presenting low back pain symptoms is presented. The technique, performed on an out patient basis is well tolerated. The MR follow-up controls regularly showed an expansion of the paraspinal muscles. The overall results obtained on this preliminary non uniform series showed encouraging results with 77.5% of very good or good results.

Objective The aim of this article is to present a new technique for minimally invasive treatment of varicose veins disease of lower extremities. Methods One-shot scleroembolization is a new technique designed for the treatment of varicose veins of the lower extremities, which associates a mechanical interruption of the sapheno-femoral junction to classic sclerotherapy with no need for surgery or anesthesia. This is achieved with the combined use of a coil positioned in the terminal portion of the great saphenous vein and a foamed sclerosant drug. Results At three months’ follow-up no complications have been observed. The great saphenous vein was still occluded in all patients (nine out of nine). Conclusions One-shot scleroembolization seems to be an effective technique for the treatment of varicose veins disease in outpatients, with the advantage of causing little distress to the patient.
