Achieve Closed Reduction of Irreducible,Unilateral Vertically Displaced Pelvic Ring Disruption with an Unlocking Closed Reduction Technique

ObjectiveTo be able to treat irreducible unilateral vertically displaced pelvic ring disruption (UVDPRD) using closed reduction, we introduced a technique named Unlocking Closed Reduction Technique (UCRT) and evaluated its effectiveness with improved pelvic closed reduction system (PCRS).MethodsA retrospective study was performed in our department. Between January 2014 and December 2017, 43 patients whose UVDPRD were not successfully reduced using transcondylar traction. Subsequently, they were treated with UCRT using improved PCRS. The study included 19 male and 24 female patients, with a mean age at the time of the operation of 46.2 years. During surgery, operation time and blood loss were recorded. Post‐surgical reduction quality was evaluated using Matta scoring criteria and patient lower‐extremity functional outcome was evaluated using Majeed functional scoring criteria.ResultsWhen used with improved PCRS, UCRT achieved pelvic reduction in all 43 cases of irreducible UVDPRD with postoperative pelvic reduction quality rated excellent and good for 42/43 (97.6%) patients according to the Matta scoring criteria (Matta Score < 10 mm). While no post‐surgical complications emerged as the direct result of UCRT in this cohort of patients, 8/37 patients who were treated with subcutaneous supra‐acetabular pedicle screw internal fixation (INFIX) for anterior ring fixation developed lateral femoral cutaneous nerve injury but recovered 6 months postoperatively. No revision surgery was performed on any of the recruited patients. All patients'' lower‐extremity functionality was rated excellent with an average Majeed function score of 94.3 during the last follow‐up at an average of 41.6 months postoperatively.ConclusionWith excellent surgical and functional outcomes in patients with irreducible UVDPRD, improved PCRS‐assisted UCRT proved to be a safe and effective method for the treatment of irreducible UVDPRD.     

Endoscopic therapy of weight regain after bariatric surgery

Weight regain following primary bariatric surgery occurs in a significant proportion of patients and is attributed to epidemiological, anatomical and metabolic factors. Surgical revision of these patients has significant risks and limited benefits. Endoscopic revisions that reduce gastric pouch size and diameter of the gastrojejunal anastomosis may offer an effective, safe, less invasive and even reproducible treatment. We herein discuss the indication, selection and feasibility of different endoscopic techniques that could be used in the management of weight regain following primary bariatric surgery. Future research could optimize a personalized approach not only in the endoscopic management but also in combination with other therapeutic modalities for weight regain after bariatric surgery.     

Progress of laser and light treatments for lower eyelid rejuvenation

Laser and light treatments have recently become popular owing to its efficacy in treating laxity, rhytids, hyperpigmentation of the lower eyelids, and drooping of septum fat. For several decades, our department has explored the application of laser and light treatment for eye rejuvenation. This paper summarizes common treatment methods and analyzes the published literature on the indications and outcomes of multiple laser and light treatments for lower eyelid rejuvenation. An extensive survey of peer-reviewed literature was performed using PubMed, with the search terms “noninvasive treatment”, “infraorbital”, “palpebral bags”, “lower eyelid”, “radiofrequency (RF)”, “laser”, “nonsurgical skin tightening”, and “noninvasive fat reduction”. The results showed that the use of lasers, intense pulsed light (IPL), monopolar RF, bipolar RF, AdipoLASER rejuvenation (ALJ), and fractional RF microneedling are safe and effective treatments for palpebral bags. We conclude that using Q-switched lasers, IPL, RF, ALJ, and fractional RF microneedling is safe and effective for lower eyelid rejuvenation, with minimal complications and quick recovery. Further research and development of optoelectronic therapy may encourage breakthroughs in lower eyelid treatment, such as simplified complex surgery and noninvasive methods.     

Morel-Lavallée lesion diagnosed 25 years after blunt trauma

IntroductionMorel-Lavallée lesions are closed degloving injuries in which the skin and subcutaneous tissues separate from the underlying fascia secondary to a shearing force. These injuries are uncommon and can be misdiagnosed in acute settings. If treated incorrectly, they can recur, causing complications requiring multiple surgical interventions. Therefore, it is important to discuss the clinical presentation and imaging characteristics in order to improve their diagnosis and management.Presentation of caseThis is the case of a 44-year-old male patient with a Morel-Lavallée lesion of the left thigh that presented 25 years after trauma. He was successfully treated with open surgical excision. The patient underwent multiple surgical interventions before the lesion was accurately diagnosed and treated.DiscussionMorel-Lavallée injuries can lead to chronic symptoms, such as pain and swelling, affecting the patient’s quality of life. Treatment options include minimally invasive procedures, such as compression bandages or percutaneous drainage. However, if diagnosed late, a fibrotic capsule can form, which may require surgical excision. Our patient was diagnosed more than 20 years after the trauma. Earlier noninvasive treatment options were unsuccessful.ConclusionThe patient was treated with open surgical excision of the chronic lesion. There was no report of any recurrence up to 10 months after surgery. Such lesion treatments should be guided based on the chronicity of the injury and the patient’s symptoms. To the best of our knowledge, this is the first case with such delayed presentation.

Long-term effects of eliglustat on skeletal manifestations in clinical trials of patients with Gaucher disease type 1

PurposeMost patients with Gaucher disease have progressive and often disabling skeletal manifestations. We examined the long-term effect of eliglustat treatment on bone outcomes in clinical trials in adults with Gaucher disease type 1.MethodsData from 4 completed phase 2 and 3 trials were evaluated in treatment-naïve patients or patients switching to eliglustat from enzyme replacement therapy (ERT).ResultsOverall, 319 of 393 (81%) eliglustat-treated patients remained in their trials until completion or commercial eliglustat became available. Mean eliglustat treatment duration ranged from 3.3 to 6.5 years. In treatment-naïve patients and ERT-switch patients, frequency and severity of bone pain decreased during eliglustat treatment. Mean lumbar spine T-scores shifted from abnormal to normal in treatment-naïve patients and remained in the healthy reference range or improved modestly in ERT-switch patients. Mean total bone marrow burden score shifted from marked-to-severe to moderate in treatment-naïve patients and remained moderate in ERT-switch patients. MIP-1β (marker of active bone disease) was elevated at baseline and decreased to the healthy reference range in treatment-naïve patients and remained in the healthy reference range among ERT-switch patients.ConclusionThese findings confirm the long-term efficacy of eliglustat on skeletal complications of Gaucher disease in treatment-naïve and ERT-switch patients.     

The role of law enforcement in minimizing the harm resulting from illicit drugs

Illicit drugs have become a major global problem in recent decades following considerable recent political change, including the collapse of communism and the formation of international super-states to increase trade. Despite increasing collaboration between law enforcement authorities in different countries, illicit drug problems appear likely to increase in the future because of the vast profits available, continuing (and increasing) demand and more permissive attitudes concerning drugs among young people. While rejecting legalization or decriminalization, the search for more effective responses by law enforcement authorities and the community generally must be stepped up. Police services continue to play an important role restricting the availability of illicit drugs but increasing emphasis needs to be given to reducing demand, including more available and more effective preventive drug education in schools. Police also need to work with harm reduction approaches devised to reduce the negative consequences of drug use for those who continue to use illicit drugs. New measures proposed in Britain are outlined. These stress the importance of a multi-sectoral approach operating at both national and local levels with the objective of reducing drug-related crime, reducing the acceptability and availability of illicit drugs and reducing the harmful consequences of illicit drug use. Harm reduction requires a commitment for close collaboration between police and drug treatment services to maximize the effectiveness of needle-exchange schemes and other harm reduction approaches. Cautioning, now commonly used in Britain for selected minor drug offences, has a number of benefits including reducing criminal justice costs. Greater emphasis must be placed on diversion schemes involving close links between police and drug treatment services. Future progress requires firm commitments to providing adequate and effective drug treatment services, conducting research to develop and evaluate more effective diversion schemes, improving collaboration between sectors and effective leadership. In addition to the major costs of illicit drug use to the community, the huge cost to individuals must remain a major focus driving the search for more effective responses to the problems resulting from illicit drugs.     

Harm reduction in the developing world

This paper examines harm reduction from the perspective of poor countries. In considering which elements of the broad approach are suitable for adaptation and adoption by poor countries, there is a need to examine critically the arguments put forth in support of it and which, if any, of these are supported by evidence. There are also significant indirect influences that the approach is likely to have on how drug use is understood and interpreted by wider society. The likely impact of these on areas other than simply services directed to drug users needs to be assessed. There are some features regarding harm caused by alcohol and other drug use that are specific to poor countries. Most important among these is that levels of use which are not deemed to be harmful in rich societies cause grave harm through diverting meagre resources away from survival needs in the poor world. Alcohol, as well as other drugs, tends in deprived settings to cause dependence and other problems much earlier in people's drinking careers and at much lower levels of consumption than in rich countries.
