Filiz Ateş, Can A Yucesoy
Botulinum toxin type A (BTX-A) effects on the mechanics of non-injected antagonistic muscles are unknown. The aim was to test the following hypotheses in a rat model: BTX-A injected into gastrocnemius medialis (GM) and lateralis (GL) (1) decreases forces of the antagonistic tibialis anterior (TA) and extensor digitorum longus (EDL), (2) reduces length range of force exertion and (3) increases passive forces of the TA, and (4) changes inter-antagonistic and inter-synergistic epimuscular myofascial force transmission (EMFT)...

Primary hemifacial spasm is a hyperactive cranial nerve syndrome. The cause is always a neurovascular compression, generally at the root exit zone from the brainstem. Its curative treatment is microvascular compression, that may be performed as a first option, or secondarily when botulinum toxin injections fail.

Iatrogenic botulism resulting from the substantial increase in use of botulinum neurotoxin type-A (BoNT-A) treatment is rarely reported. We aimed to describe a large iatrogenic botulism outbreak in Egypt in June-July 2017. Nine patients developed botulism after receiving intramuscular injections of BoNT-A (dose: 200-300 IU) to treat cerebral palsy (N=7), spastic dystonia (N=1), and hyperhidrosis (N=1). Detailed findings were available in 5/9 cases. Patients were admitted to the hospital 5-10 days after the BoNT-A injection...

Dear Editor, Pitted keratolysis (PK), also known as keratosis plantaris sulcatum, is a non-inflammatory, bacterial, superficial cutaneous infection, characterized by many discrete superficial crateriform ''pits'' and erosions in the thickly keratinized skin of the weight-bearing regions of the soles of the feet (1). The disease often goes unnoticed by the patient, but when it is noticed it is because of the unbearable malodor and hyperhidrosis of the feet, which are socially unacceptable and cause great anxiety to many of the patients...

Bone fractures in older adults are often preceded by a loss of muscle mass and strength. Likewise, bone loss with prolonged bed rest, spinal cord injury, or with exposure to microgravity is also preceded by a rapid loss of muscle mass. Recent studies using animal models in the setting of hindlimb unloading or botulinum toxin (Botox) injection also reveal that muscle loss can induce bone loss. Moreover, muscle-derived factors such as irisin and leptin can inhibit bone loss with unloading, and knockout of catabolic factors in muscle such as the ubiquitin ligase Murf1 or the myokine myostatin can reduce osteoclastogenesis...

RATIONALE: Pantothenate kinase-associated neurodegeneration (PKAN) is a rare autosomal recessive disease. Progressive motor symptoms such as dystonia and spasticity begin in childhood and relentlessly become incapacitating later in life. Treatments including anticholinergics and iron chelation are usually ineffective. Botulinum toxin type A (BoNT-A) is effective for adult patients with dystonia or spasticity. PATIENT CONCERNS: We reported a 10-year-old female patient with advanced PKAN, manifesting as generalized dystonia and spasticity...

Pantothenate kinase-associated neurodegeneration (PKAN) is a neurodegenerative disorder characterized by iron accumulation in the globus pallidus (GP) of the brain (neurodegeneration with brain iron accumulation [NBIA]), which is characterized by dystonia and spasticity resulting in postural difficulties. A 33-month-old boy was admitted with a pronounced gait disturbance. Marked hypertonicity in the patient's both calf muscles was noted, resulting in waddling with repeated slip-falls. NBIA was suspected by high T2 intensity in the GP on brain MRI, then it was confirmed by detecting PANK2 mutation...

Prolonged intubation is known to bring on postextubation dysphagia (PED) in some patients. We have noted that there were some studies to investigate specific type and pattern of PED, which showed large variety of different swallowing abnormalities as mechanisms of PED that are multifactorial. There are several options of treatment in accordance with the management of these abnormalities. A botulinum toxin (BoT) injection into the upper esophageal sphincter (UES) can improve swallowing functions for patients with this disorder, by working to help the muscle relax...

BACKGROUND: Botulinum toxin A (BoNT-A) is a novel treatment for chronic lateral epicondylar tendinopathy. Preliminary studies have demonstrated promising results; however, confirmation of the effectiveness of BoNT-A treatment and further assessment of its side effects are required. This study investigated the analgesic effects of BoNT-A in the treatment of chronic lateral epicondylar tendinopathy. METHODS: This was a phase-III, single-center, randomized, double-blinded, placebo-controlled study including 60 patients with chronic lateral epicondylar tendinopathy that had been resistant to treatment for >6 months...

REVIEW
Philip R Cohen
Genital rejuvenation is applicable not only to women (vaginal rejuvenation) but also to men (scrotal rejuvenation). There is an increased awareness, reflected by the number of published medical papers, of vaginal rejuvenation; however, rejuvenation of the scrotum has not received similar attention in the medical literature. Scrotal rejuvenation includes treatment of hair-associated scrotal changes (alopecia and hypertrichosis), morphology-associated scrotal changes (wrinkling and laxity), and vascular-associated scrotal changes (angiokeratomas)...

Joan Leung, Katarina Stroud
Purpose: Serial casting for ankle contractures is traditionally performed in prone, a position that patients may not easily tolerate. Also, although serial casting is effective in correcting contracture, its effect dissipates quickly. This case report describes a procedure for performing casting for ankle contractures in a supine or sitting position. It also describes a process that enables the effect of serial casting to be maintained long term. Client Description: The client was an adult who had suffered traumatic brain injury and severe bilateral ankle contractures...
