Neurological and functional outcome in traumatic central cord syndrome.

STUDY DESIGN: Retrospective analysis of in-patient stay and prospective follow-up. OBJECTIVES: To study neurological and functional outcomes after traumatic central cord syndrome (TCCS). SETTING: Regional Spinal Unit of Florence, Italy. METHODS: In total, 82 patients, admitted for acute rehabilitation to our Centre (1996-2002) with a diagnosis of TCCS entered the study. Data on admission and discharge were collected for assessments performed at 18 months of injury or later. Data included: cause of injury, gender, type of vertebral lesion, treatment, time of hospitalisation (LoS), ASIA/ISCOS Impairment Scale, neurological examination, functional independence measure (FIM) on admission and discharge. Additional measures included the walking index for spinal cord injuries (WISCI), bladder management, FIM, spasticity on discharge/follow-up and neuropathic pain at follow-up. Correlations were performed on outcome measures in relation to age, treatment, LoS, spasticity and neuropathic pain. RESULTS: Average age was 52 (16-82) years. Causes included falls (47%), road traffic accidents (36%) and sport (7%). Of patients, 45% were treated surgically and 55% conservatively. LoS was 120 days (24-390), but less for those treated without surgery. Patients under 65 years had better outcomes with less neuropathic pain. Neurological and functional recovery was observed on discharge from rehabilitation, which continued in the period following discharge. Spasticity was equally present in all age groups. No difference in outcome was found as a result of spine surgery. CONCLUSIONS: Patients with TCCS are older than other spinal cord injured patients, but often show improvement after discharge. Improvement in subjects under 65 years was significantly better than for those over 65 years.

A case of forearm amputation after ovarian stimulation for in vitro fertilization-embryo transfer.

OBJECTIVE: To report a case of forearm amputation after ovarian stimulation for IVF-ET. DESIGN: Case report. SETTING: A university hospital. PATIENT(S): A 41-year-old woman, who had coagulation disorder as a result of an ovarian hyperstimulation syndrome (OHSS) for IVF-ET. INTERVENTION(S): Retrospective evaluation of angiographic studies and surgical treatment. MAIN OUTCOME MEASURE(S): Medical follow-up after forearm amputation due to OHSS. RESULT(S): The patient underwent many cycles of IVF-ET with administration of purified FSH (75 IU 10 times per day, for 12 days) and chorionic gonadotropin (5,000 IU). The patient had a coagulation disorder as a result of OHSS, with thrombosis of the axillary vein, recurring after thromboarterectomy and leading to the paradoxical result of the amputation of an arm. CONCLUSION(S): An ethical evaluation of this case is mandatory, since the desire for pregnancy, the role of medical science, health, and human life itself are all factors involved.

[Spontaneous grade I bundle of His block. Clinical, electrocardiographic and electrophysiological studies in 37 patients].

The clinical, ECG and electrophysiological data of 37 patients (28 males and 9 females) with spontaneous intra-hisian block are reported. Of these patients, 11 had hypertensive heart disease and 5 had ischemic heart disease with previous myocardial infarction; in 21 patients, clinical signs of heart disease were not evident. In 18 patients, a single or recurrent episode of syncope had occurred. One patient had junctional rhythm and 36 sinus rhythm; among these, 12 patients presented PR greater than 200 msec (7 with a narrow and 5 with a wide QRS); 12 patients had a single or bilateral bundle branch block; 12 had a normal ECG. The electrophysiological study showed a split H-H1 in 22 patients, a wide His deflection (H greater than 25 msec) in 4 and HV greater than 65 msec with narrow QRS in 11. In 17 patients a more or less marked sinoatrial node and/or atrioventricular node dysfunction was present. Atrial pacing, performed in all, induced 2nd degree Mobitz 2 intra-hisian block in 9 patients. Ajmaline was used in 16 patients but induced a complete intra-hisian block in only one. In 28 patients a preventive pacemaker was implanted after electrophysiological study. During the follow-up (mean 25 months/pt.), 38% of the patients developed complete atrioventricular block. No recurrence of syncope occurred in the paced patients. Comparison of patients who developed atrioventricular block and those who maintained normal atrioventricular conduction did not show differences as far as heart disease, previous syncope, ECG pattern and results were concerned.(ABSTRACT TRUNCATED AT 250 WORDS)

[Cutaneous lipid excretion].

In this research we have studied the lipids excretion of skin by comparison of three groups of subjects at first age, young age and old people. We evidence the amount of the lipidic fractions and the differences between the ages in the lipids of skin and their components. We have also underlined the great significance of the skin as an important factor in the homeostasis.

[Plasma variations of pituitary hormones during extracorporeal circulation].

In this research we have determined the behaviour of hypophisary hormones determined by radioimmunoassay. We have noted a constant increase of GH and HPrL. In one case we have seen also the decrease of LH and FSH. This changes are determined by the large dose of heparin necessary during C.E.C.

[Variations in plasma protein components during extracorporeal circulation].

In this research we have determined the behaviour of proteic plasmatic pattern and some enzymes during extracorporeal circulation and we noted a constant increase of albumin and of the ratio Alb/Glob. We observed also variations of some enzymes. Our opinion according other AA. is that this changes are determined principally by the large dose of heparin necessary during the C.E.C.

[Cutaneous evaporimetry. IX. Cutaneous water loss in old age].

The cutaneous water loss (CWL) were investigated in 15 old human subjects by Evaporimeter Ep-1. The mean value of the CWL resulted 11,9 +/- 4,3 g/h. This result is significantly lower compared with the value of normal people equal to 17, 5 +/- 4,0 g/h as reported in foregoing notes.

[Pulmonary silicosis associated with MacLeod syndrome: a case report].

The paper reports a case of silicosis associated with idiopathic unilateral hyperlucent lung--MacLeod's disease (ML)--in a 65-year old miner. ML had not been diagnosed before this clinical observation and the patient had been exposed to silica dust for about 15 years as a truck operator in water supply tunnelling work in central Italy. Impaired ventilatory function due to left pulmonary dystrophy was the favouring or even the causal factor of dust accumulation in the functionally active right lung and of the tissue reaction to the dust, leading to interstitial fibrosis. A radiological diagnosis of p 1/0 pneumoconiosis was made according to the 1980 International Labour Office classification. Clinical, radiological and functional findings indicated the presence of respiratory failure as a result of the sum of silicotic and dystrophic lesions. Two combined pulmonary scintigraphic examinations with Tc99 perfusional and mTc-DPTA inhalatory methods revealed peculiar alterations: absence of ventilation associated with severe vascular impairment in the left lung, inequality of the ventilation/perfusion rate, due to pneumoconiosis, in the right lung. MacLeod's disease is rare, but must be considered as a mandatory contra-indication for work involving dust exposure risk since it is one of the predisposing factors which can cause an occupational disease even if environmental exposure standards are observed.
