This paper describes an assisted local anaesthetic technique which we have used almost exclusively for extracapsular cataract extraction and posterior chamber intraocular lens implant surgery over the last 12 months. This ALACS technique was developed from a combined neurolept-local anesthetic into an assisted local anaesthetic suitable for day-stay cataract surgery. The technique combines the advantages of purely local (retrobulbar and facial) anaesthesia with the advantages usually inherent in a good general anaesthetic. Thus the patient is in a state of general quiescence and psychic indifference throughout the procedure. ALACS provides excellent and long-lasting akinesia and analgesia, with adequate proptosis of the eye which facilitates surgical access. ALACS is suitable for almost all adult cataract and implant surgery. Our results in 104 cases of ALACS are reviewed in terms of visual results and complications both ocular and anaesthetic; the results appear good and the complications minimal. The results of blood gas estimations done intraoperatively in a small number of patients are also presented, and suggest that the technique is systemically safe.

Myotonic dystrophy (m.d.) is an autosomal dominant multisystem disorder involving muscles, brain, heart, eye, endocrine system, alimentary and respiratory systems. M.d. is the most frequent cause of muscle dystrophy. Unstable CTG trinucleotide repeat at 3' untranslated end of the myotonic protein kinase gene on chromosome 19q 13.3 is the molecular basis of the disease. Normal length of CTG trinucleotide repeat is 5-40. Molecular mechanism of the myotonic dystrophy is discussed. Cataract, heart dysfunction, endocrine organs dysfunction, gallbladder stones, impotence are characteristic changes in patient with m.d. Apathy, drowsiness, sometimes dementia point to central nervous system involvement. Clinical course, correlation between CTG expansion and clinical manifestation are described. Nowadays progress in molecular genetic allows to make the diagnosis by DNA examination. Prenatal diagnosis is also possible.

The authors describe a case of a 53 years old man with myotonic dystrophy. Based on characteristic clinical symptoms and EMG results the diagnosis was established and proved on DNA examination. Myotonic dystrophy gene analysis showed on 3' untranslated region one hundred and fifty CTG triplet repeats. The accessory examinations revealed: cataract arrhythmias, gallbladder stones, impotence, cerebral atrophy on neuroimaging (CT and MRI). Apathy, somnolence, concentration troubles were present. Pedigree of the presented patient and possibility of spontaneous mutation are discussed.

Newer generation antidepressant drugs (ADs) are widely used as the first line of treatment for major depressive disorders and are considered to be safer than tricyclic agents. In this critical review, we evaluated the literature on adverse events, tolerability and safety of selective serotonin reuptake inhibitors, serotonin noradrenaline reuptake inhibitors, bupropion, mirtazapine, trazodone, agomelatine, vilazodone, levomilnacipran and vortioxetine. Several side effects are transient and may disappear after a few weeks following treatment initiation, but potentially serious adverse events may persist or ensue later. They encompass gastrointestinal symptoms (nausea, diarrhea, gastric bleeding, dyspepsia), hepatotoxicity, weight gain and metabolic abnormalities, cardiovascular disturbances (heart rate, QT interval prolongation, hypertension, orthostatic hypotension), genitourinary symptoms (urinary retention, incontinence), sexual dysfunction, hyponatremia, osteoporosis and risk of fractures, bleeding, central nervous system disturbances (lowering of seizure threshold, extrapyramidal side effects, cognitive disturbances), sweating, sleep disturbances, affective disturbances (apathy, switches, paradoxical effects), ophthalmic manifestations (glaucoma, cataract) and hyperprolactinemia. At times, such adverse events may persist after drug discontinuation, yielding iatrogenic comorbidity. Other areas of concern involve suicidality, safety in overdose, discontinuation syndromes, risks during pregnancy and breast feeding, as well as risk of malignancies. Thus, the rational selection of ADs should consider the potential benefits and risks, likelihood of responsiveness to the treatment option and vulnerability to adverse events. The findings of this review should alert the physician to carefully review the appropriateness of AD prescription on an individual basis and to consider alternative treatments if available.
