The therapeutic effect of moclobemide, a reversible selective monoamine oxidase A inhibitor, in Parkinson's disease.

In this open study, the therapeutic effect of moclobemide, a reversible selective monoamine oxidase A inhibitor, was tested in 20 patients with Parkinson's disease who developed levodopa-induced motor response complications. Moclobemide as adjunct therapy reduced "off" time duration for 27%, without an overall motor and functional improvement during their "on" periods. Since it was well tolerated, moclobemide may be specially indicated in elderly or depressed fluctuating parkinsonian patients.

Retrobulbar hydatid cyst: assessment of two cases.

A 54-year-old man with a unilocular hydatid cyst within the infero-posterior angle of the orbit and a 6-year-old male child with a unilocular hydatid cyst within the supero-medial angle of the orbit are presented. The retrobulbar cysts were diagnosed with computed tomography and ultrasonography and were treated after serologic confirmation.

Impairment of cortical inhibition in writer's cramp as revealed by changes in electromyographic silent period after transcranial magnetic stimulation.

Changes in silent period (SP) duration following transcranial magnetic stimulation (TMS) set at 20% above the motor threshold were studied in six subjects suffering from writer's cramp, while performing dystonic movement and during voluntary isometric contraction of the muscles mostly involved in the dystonic movement. Dependency of SP duration on the intensity of preceding muscle contraction was compared on both affected and healthy side. In all subjects SP duration during dystonic contraction was shorter than during voluntary contraction of the similar strength performed with the same hand.

Symptomatic dystonias associated with structural brain lesions: report of 16 cases.

Background: Symptomatic (secondary) dystonias associated isolated lesions in the brain provide insight into etiopathogenesis of the idiopathic form of dystonia and are a basis for establishing the possible correlation between the anatomy of a lesion and the type of dystonia according to muscles affected.

Methods: In 358 patients with differently distributed dystonias, a group of 16 patients (4.5%) was encountered in whom dystonia was associated with focal brain lesions.

The presence of tRNA pseudogenes in mammalia and plants and their absence in yeast may account for different specificities of pre-tRNA processing enzymes.

Six of 13 cloned members of the human tRNA(Val) gene family code for tRNA(Val) pseudogenes, of which all but one are transcribed efficiently in HeLa cell extracts. Due to single or multiple mismatches in stem regions, the corresponding pre-tRNAs are resistant against the action of human 5'- and 3'-processing enzymes and are thus prevented from being converted to mature tRNAs. Surprisingly, all of them are accurately and efficiently processed to mature-sized tRNA in yeast nuclear extract.

Pseudomyxoma of the pleural and peritoneal cavities.

Pseudomyxoma peritonei is a rare clinical manifestation of mucin producing adenocarcinomas. An extensively metastased adenocarcinoma developed a pseudomyxoma that affected not only the peritoneal cavity but also the pleura.

The first human genes for tRNA(ArgICG), tRNA(GlyUCC), and tRNA(ThrIGU) and more tRNA(Val) pseudogenes: expression and pre-tRNA maturation in HeLa cell-free extracts.

A functional tRNA(Val) gene, which codes for the major tRNA(ValIAC) isoacceptor species, and three new tRNA(Val) pseudogenes have been isolated from human genomic DNA. Two tRNA(Val) pseudogenes and a tRNA(Val) variant gene were found to be associated with tRNA genes encoding tRNA(ArgICG), tRNA(GlyUCC), and tRNA(ThrIGU), respectively, on distinct DNA fragments. All tRNA genes, including the pseudogenes, are actively transcribed in HeLa nuclear extract.

[Pseudomyxoma of the pleura and peritoneum].

A case is presented of 41 year old patient with a very rare form of clinical manifestation of adenocarcinoma with a large mucinous ascites with abdominal distention and a massive left hemithoracic content with same characteristics. Two years prior the patient suffered from acute abdomen and underwent apendectomy with slow wound healing and a stomach edema 6 months later with a finding of smaller changes on the left side of the thorax. The patient was hospitalized when he already had an advanced stage of the disease.

[Analysis of hospitalized tuberculosis patients at the Institute for Pulmonary Diseases and Tuberculosis in Belgrade, Serbia during 1988].

The report presents the analysis of TB patients treated at the Institute for lung diseases and tuberculosis of SR of Serbia during 1988--a total of 567 or 10.18% of discharged patients. There were 77% TB patients from Belgrade and 23% from the province.

Improved port film quality with six megavolt linear accelerator.

This article introduces a new technique for accurate verification of therapy treatment sites with radiographs. It can be used not only on most linear accelerators, but also on cobalt treatment units, with slight variation in exposure technique. It can eliminate the poor image detail presently seen and accepted at various therapy instiutions with a new method of quality control.
