This document discusses selective nerve transfer to the anterior branch of the axillary nerve. Specifically, it describes the nerve to the long head of the triceps as being expendable, a pure motor nerve with a constant origination point in proximity to the axillary nerve and similar size. The document concludes that selective transfer of the nerve to the long head of triceps to the anterior branch of the axillary nerve can restore shoulder abduction without requiring muscle re-education.

Triceps to axillary nerve transfer is used in partial plexus injuries where the C5/6 component is damaged and the C7/8 and T1 are intact. The typical indication is in the C5 or C5/6 avulsion injury but it may also be used in cases of C5/6 rupture where presentation is delayed, grafting of the upper trunk has not been successful or in continuity lesions of the upper trunk that failed to reinnervate. It may also be used to salvage the axillary nerve rupture at the quadrilateral space associated with high energy shoulder dislocation or the rare non-recovering isolated lesion in continuity of the axillary nerve following a low energy shoulder dislocation.

Distraction osteogenesis is a method of producing unlimited quantities of living bone directly from a special osteotomy by controlled mechanical distraction. The new bone spontaneously bridges the gap and rapidly remodels to a normal macrostructure for the local bone.
The Stone Clinic is a sports medicine clinic in San Francisco, California, offering orthopaedic surgery and medical care, physical therapy and rehabilitation, and radiology imaging services. The Stone Clinic was founded by Kevin R. Stone, M.D., an orthopaedic surgeon, combining himself with a team of nurses, physical therapists, imaging specialists, and patient coordinators, in 1988 to focus on caring for injured athletes and people experiencing arthritis pain.
The Stone Clinic is founded on the goal of rehabilitating all patients to an operating level higher than before they were injured. The Stone Clinic specializes in sports medicine and injury treatment of knee, shoulder, and ankle joints. Stone has lectured and is recognized internationally as an authority on cartilage and meniscal growth, replacement, and repair. Stone and the Stone Clinic are known for the development of the paste grafting surgical technique in 1991, combined with meniscus replacement, which are biologic joint replacement procedures for the regeneration of the knee joint. Surgical procedures were subjected to rigorous outcomes analysis with the results reported in peer reviewed journals. The surgical techniques have been taught to surgeons in the US and worldwide, through lectures and videos.
Nursing students, medical students, residents, fellows, and other physicians from various institutions around the world, rotate through The Stone Clinic and mentor with Stone. The Stone Clinic hosts the annual Meniscus Transplantation Study Group Meeting as well as the annual Professional Women Athlete's Career Conference.

Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.

Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:

Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.

Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.
