Metoclopramide hydrochloride is an antiemetic and gastric motility stimulant with a wide variety of extrapyramidal side effects, including parkinsonism. We describe two patients with end-stage renal disease secondary to diabetes mellitus treated with hemodialysis who developed extrapyramidal symptoms during treatment with metoclopramide. One patient with preexisting, well-controlled Parkinson's disease developed increasing rigidity and bradykinesia that became completely refractory to treatment with L-dopa and bromocriptine while taking metoclopramide for diabetic gastroparesis. A second patient with no history of Parkinson's disease developed a resting tremor and facial dyskinesia during treatment with metoclopramide. In both cases, discontinuation of metoclopramide therapy led to prompt improvement of symptoms.

The botulinum A toxin inhibits the release of acethylcoline from the vesicles of presynaptic neuronal end plates. Its effect is a transient pharmacological neurectomy. The toxin is used more and more widespreadingly. It selectively inhibits certain muscles or groups of muscles. Its use is of outstanding importance in the treatment of blepharospasm, a disease possibly causing transient functional blindness. This blindness develops randomly, with undetermined duration, therefore it may even threaten the life of the patient. There is no alternative treatment. In ophthalmology, the toxin is used in the therapy of strabismus and nystagmus, as well as replacing entropion operations. Most often its use is suggested in the treatment of focal dystonies, dysphonia, tremor palatinus, dysphagia, spasm of the oesophagus sphincter muscle, nasal hypersecretion, hemifacial spasm, headaches, focal hyperhydrosis, proctalgia fugax, diabetic gastroparesis and difficulties in urination. In the past few years, the toxin has been used for esthetic reasons as well. By relaxing the muscles causing wrinkles, non-permanent result may be reached with its use. The botulinum A toxin does not have general side effects. As local side effects, haematomas and unwanted, transient paresis of the neighboring muscles can be mentioned.

Predictors of gastric emptying (GE) in patients with idiopathic Parkinson's disease (PD) of a solid and liquid meal are not well defined. For measurement of GE 80 patients with PD were randomly assigned to receive either a solid meal (250 kcal) containing 13C-octanoate (n = 40) or a liquid meal (315 kcal) with 13C-acetate (n = 40). All patient groups were off medication affecting motility and were matched for age, gender, body mass index, disease duration and severity, using Unified Parkinson's Disease Rating Scale (UPDRS). Gastric emptying was compared with a healthy control group (n = 40). Multiple regression analysis was used to determine predictors of gastric emptying. Exactly 88% and 38% of PD patients had delayed GE of solids and liquids respectively. Solid and liquid emptying was similar in women and men. There were no differences in GE in PD patients < 65 years of age when compared with patients > or = 65 years. Multiple regression analysis showed that motor handicaps such as rigour and action tremor are independent predictors of solid GE (r = 0.68, P < 0.001). The severity of motor impairment, but not any other neurological symptom, as assessed by UPDRS is associated with gastroparesis in PD and solid emptying is more likely to be delayed.

Multiple sclerosis (MS) is the most common disabling chronic disease of the central nervous system among young adults. These patients suffer from variety of symptoms that have a profound affect on their working ability, activities of daily living and general quality of life. Treatment of these symptoms is important in order to relief them and improve daily function and quality of life. Many of these symptoms are often resistant to treatment. Botulinum toxin A (BTX) is mainly used for spasticity and bladder dysfunction in MS. It is an effective treatment option for spasticity of the thigh adductor, pes equinus, striatal toe or adductor of the shoulder joint. BTX injections are effective in reducing incontinence episodes and urinary urgency, daytime frequency and nocturia, as well as sustained improvements in quality of life of MS patients with detrusor overreactivity. In addition, BTX is potentially effective in treating pain, trigeminal neuralgia, tremor, neuro-ophthalmologic complications, facial myokymia, gastroparesis, sialorrhea, and hyperhidrosis, however no studies have confirmed its efficacy in MS patients.
