Airbag injuries of the hand: a case-series and literature review.

Motor vehicle accidents are a significant cause of morbidity and mortality worldwide. Airbags aim to reduce the severity of motor vehicle accidents, but their deployment is not without risks. This study presents five cases presenting with diverse forms of upper extremity injuries following airbag deployment. The presented cases highlight the variety of clinical presentations, the differences in diagnostics in terms of imaging modalities, as well as the spectrum of possible outcomes from complete healing to decreased range of motion to persistent neurological symptoms. Understanding the mechanisms and presentations of such injuries can only help in improving and creating new strategies for the prevention of such injuries, as well as their management.

A Simple, Cost-effective Microsuction Device.

In our proposed device, we converted a large suction tube into a small tube with reduced suction velocity. This can aid in microsurgical procedures in which meticulous suctioning while minimizing trauma to the surrounding structures is essential. This device can relieve the surgeon from having to be cautious about injuring any anastomoses or neurovascular structures while suctioning.

Isolated Congenital Lower Limb Lipoatrophy: A Case Report and Literature Review.

Lipoatrophy and lipodystrophy can often be used interchangeably in the literature. However, there are some key differences. Inflammation plays a preliminary role in subcutaneous adipose tissue (SAT) loss in lipoatrophy, whereas lipodystrophy does not. There are acquired causes of SAT loss such as injurious stimuli (ie, drug injections), panniculitis, or even microtrauma. Moreover, there are congenital causes such as familial partial lipodystrophy, which follows a more localized pathology, and congenital generalized lipodystrophy, which follow a diffuse spread of SAT loss. These etiologies are further subdivided based on the mutations and clinical presentations. We present a case of a 12-year-old girl with unilateral left lower limb SAT loss since birth, without any signs of inflammation. Therefore, a diagnosis of familial partial lipodystrophy was suspected. However, genetic testing appeared unremarkable. The patient is set for conservative therapy until late adolescence for possible fat grafting.

Submental liposuction with VASER complicated with hidradenitis suppurativa in neck area: a case report.

Hidradenitis suppurativa (HS) is a chronic inflammatory disorder that is characterized by deep-seated painful nodules, classically in the intertriginous skin and apocrine gland-rich areas of the body such as the anogenital, axillary, inframammary and inguinal regions. This is a case of a 35-year-old female, who is known to have gluteal HS, she underwent neck liposuction procedure that was then complicated by anterior neck HS, which is considered as an atypical location. The patient received medical treatment with antibiotics and showed huge improvement. In addition, in patients who do not show response to medical therapy, surgical treatment is usually carried out by incising the area affected and leaving the wound open to be healed by secondary intention or covering it with a skin graft if the area is extensive.

The spectrum of muscle pathologies: Three decades of experience from a reference laboratory in Saudi Arabia.

BACKGROUND: When investigating patients with a suspected neuromuscular disorder, a muscle biopsy is considered an instrumental tool to reach a definitive diagnosis. There is a paucity of publications that assess the diagnostic utilization and yield of muscle biopsies. We intend to present our experience in this regard over an extended period of more than three decades. METHODS: This is an observational retrospective cohort study in which we collected pathology reports for muscle biopsies diagnosed at our reference lab between 1986 and 2017. RESULTS: We identified a total of 461 cases of muscle biopsy performed, which fulfilled the inclusion criteria. Pediatric cases defined as ≤14 years of age constituted a significant proportion of cases (n = 275, 60%). Normal biopsies were reported in 27% of cases (n = 124), and in 4%, the biopsies were non-diagnostic. The most common pathologies reported were non-specific myopathy (n = 72, 16%), dystrophy (n = 71, 15%), and neurogenic disorders (n = 60, 13%). CONCLUSION: In conclusion, the muscle biopsy will continue to play a crucial role, as a gold standard or as a complementary investigation, in the diagnosis of certain neuromuscular disorders. Increasing the yield and accuracy of muscle pathology should be the main concern and priority to neuropathologists reporting muscle biopsies. In addition, utilizing next-generation sequencing and other molecular techniques have changed the location of muscle biopsy in the algorithm of the diagnosis of neuromuscular disorders. This paper is an urgent call to establish the Saudi Neuropathology Society and the muscle pathology and neuromuscular disorders registry.
