The Carter-Thomason Needle Suture Passer to Correct Cannula-Induced Defects and Vascular Injuries in the Abdominal Wall During Laparoscopy

Postoperative omental and bowel entrapment secondary to incisional hernias and life-threatening hemorrhage secondary to anterior abdominal wall bleeding may occur during cannula placement. The Carter-Thomason needle suture passer was used to correct 20 fascial and peritoneal cannula defects and 7 severe anterior abdominal wall bleeders. The procedure was performed quickly and successfully in all instances. The instrument provides a safe, rapid, easy, and cost-effective way to correct complications secondary to the creation of surgical ports during laparoscopic surgery.

Ectopic Pregnancy Treated by Combined Laparoscopic Surgery and Methotrexate

Conservative laparoscopic surgery using only an operative laparoscope, followed by injection of methotrexate 50 mg into the proximal segment of the involved tube, was performed successfully in seven women with ectopic pregnancy. Significant decreases in beta-subunit human chorionic gonadotropin occurred at 7, 14, and 30 days. No intraoperative or postoperative surgical complications, or side effects of methotrexate occurred. Five women became pregnant, with no miscarriages or recurrent ectopic pregnancies. This combined approach is a practical alternative to current management protocols.

The Pelosi Simplified Technique to Repair Inguinal Hernias During Gynecologic Laparoscopy

Inguinal and incisional hernias are frequently discovered during gynecologic laparoscopy. Current laparoscopic techniques to repair hernias are time consuming and require expensive procedure-specific instrumentation. The Pelosi simplified method of hernia repair, which uses an operative laparoscope, Carter-Thomason needle carriers, and standard suturing material, was performed successfully in eight women to repair inguinal hernias at the time of gynecologic laparoscopy. No intraoperative or postoperative complications occurred. None of the patients developed recurrent hernias.

CLECOS_P: clinical evolution control system on Parkinsonian patients undergoing neural transplantation.

The CLECOS_P system was conceived for registering and automating the processing of clinical evaluations performed on patients with Parkinson's disease who undergo functional neurosurgery and/or neural transplant. CLECOS_P represents the first time a computerized system is able to offer--with high precision and considerable time-savings--an integral analysis of the evolutive behavior of the universe in integrated variables at the core assessment program for intracerebral transplantations (CAPIT). CAPIT is used internationally for the evaluation and follow-up of patients with this pathology who have undergone neural transplant. We used the so-called MEDSAC methodology for the preparation of this system. The methodology that was used for the design of an intelligent system aimed at medical decision-making was based on the quantitative analysis of the clinical evolution. At the present moment, there are 20 patients controlled by this system: 11 bilaterally transplanted, 9 unilaterally (registered in ranks of 3 months before operation up to 1, 2, 3, 6, 9, 12, 18, and 24 months after operation). The application of CLECOS_P to these patients permitted the evaluation of 400 clinical variables, where a better evolutive characterization of the patients was obtained, thus getting most favorable results with personalized therapeutic methods aimed at raising their quality of life. CLECOS_P is used in a multi-user environment on a local area network running Novell Netware version 3.11.

[Self application of preventive measures and opinion about applying them to the population at the health centers of Cantabria].

OBJECTIVE: To establish the degree of fulfillment of preventive measures and health promotion recommended by the Spanish Society of Family and Community Medicine for medical staff; to determine the opinion for medical staff about the application to these preventive measures in the general population and to analyse the relationship between the self application and the recommendation to the population. DESIGN: Cross-sectional observational through questionnaire. SETTING: Health Centers in Cantabria. PARTICIPANTS: Medical staff of Health Centers. MEASUREMENTS AND MAIN RESULTS: A response of 67.9% (146 out of 215) was obtained. The results of the self application had been: smokers, 35.6%; know their TA, 89.5%; know their weight, 99.3%; know their cholesterol, 81.5%; tetanus vaccinated, 41.4%; influence vaccinated, 33.6%; hepatitis B vaccinated, 38.6%; consume alcohol in excess, 5.6%; make breasts annual exploration, 44.4%; mammography, 33.0%; cervical cytology, 73.1% protected against german measles, 87.2%. The opinion of the medical staff about the application of the preventive measures in the general population of was positive in more of 90% the respondent. We found a significant relation (p < 0.01) between self application and recommendations to the population; and the population recommendation also showed an inverse relationship with the number of years of experience in First Aid (p < 0.01). However, the statistical was low for these variables (0.2). CONCLUSION: The self application of the preventive measures in the Health Centers of Cantabria is in general better than in other Spanish regions and although, we found relations between self application and recommendation to the population the statistics potency was low for this variable.

Stereotactic retransplantation in Parkinson's disease: clinical, imaging and electrophysiological evidence of adrenal brain graft viability.

In March 1993, a patient with idiopathic Parkinson disease who had received an adrenal brain autograft 6 years before underwent bilateral stereotactic transplantation of a mesencephalic cell suspension into the striatum, in order to prevent further deterioration in his neurological condition. During the CT-guided surgical planning and the transplantation procedures, electrophysiological evidence of the adrenal graft viability was assessed. Based on these findings, we drew the preliminary conclusion that the chromaffin tissue implanted in April 1987 is still functional, which explains the clinical evolution of this patient during the postoperative long-term follow-up.

CT-oriented microrecording guided selective thalamotomy.

A further trial of CT-oriented microrecording guided stereotactic selective thalamotomy was conducted at the Centro Internacional de Restauración Neurológica, Havana City as treatment of resting tremor in 11 patients with idiopathic Parkinson's disease (PD), and in 3 other patients with intentional tremor associated with multisystemic atrophy and cerebral palsy. Three of the parkinsonian patients had undergone fetal mesencephalic tissue transplantation with significant improvement of the most debilitating symptoms of PD and stabilization of the motor state, but predominantly unilateral tremor had impaired them progressively despite increased levodopa doses. A Leksell frame was used with a novel surgical planning system and electrophysiological recordings to identify the optimal target point inside the ventralis intermedius. In all but 1 case, the tremor was totally arrested. No persistent complications were observed.

Neurotransplantation in Parkinson's disease: from open microsurgery to bilateral stereotactic approach: first clinical trial using microelectrode recording technique.

This paper summarizes the results of three controlled clinical trials related to the transplantation of embryonic ventral mesencephalic tissue into the striatum of 46 idiopathic parkinsonian patients exhibiting motor complications on standard levodopa therapy. From January 1988 to April 1990, 30 subjects with fluctuating Parkinson's disease received fetal dopaminergic tissue implants by the open microsurgical technique. In March 1992 the stereotactic approach was adopted for successive fetal mesencephalic cell suspension transplants (7 unilateral and 9 bilateral) into the caudate and putamen of parkinsonian patients with levodopa-induced complex fluctuations and dyskinesias. The neurological assessment performed 12 months before and 3-18 months after transplantation demonstrated a reduction of both the daily time spent in the 'off' condition and the number of daily 'off' periods, and a significant improvement of the motor scale. The stereotactic selective thalamotomy with microelectrode recording was introduced in January 1993, in order to provide a further potential treatment strategy; i.e., the combination of the two surgical trends in Parkinson's disease, the restorative neurotransplantation technique, and the selective lesional approach. In addition to that, microelectrode recording is also used for implantation site selection and functional characterization.

Computer-assisted CT-guided stereotactic biopsy and brachytherapy of brain tumors.

From March 1991 to September 1993, 26 patients (aged 4-78 years) with brain tumors (4 glioblastoma multiforme, 10 nonglioblastoma multiforme, 1 mixed oligoastrocytoma, 2 carniopharyngiomas, 2 meningiomas and 7 metastases) were treated with stereotactic techniques at the Centro Internacional de Restauración Neurológica, La Habana, Cuba. A total of 28 stereotactic surgical procedures were performed with no operative mortality; they included biopsies in all cases, 1 stereotactic microsurgical resection and 12 permanent implants of 192Ir, followed by external beam fractionated radiation therapy (40-60 Gy). The present paper shows that the combined use of a stereotactic approach, a comprehensive and reliable stereotactic dosimetric planning system, stereotactic brachytherapy with 192Ir and complementary percutaneous radiation treatment constitutes a promising strategy for brain tumor management.

Computer assisted CT-guided stereotactic transplantation of foetal ventral mesencephalon to the caudate nucleus and putamen in Parkinson's disease.

We report our preliminary results related to CT-guided stereotactic transplantation of foetal ventral mesencephalic cell suspension into the striatum of five patients with idiopathic Parkinson's disease. The mean age was 51 years, the evolution time of the disease ranged from 7 to 14 years, and all of them had motor complications associated with chronic L-dopa therapy. The patients were evaluated according to the Core Assessment Program for Intracerebral Transplantations (CAPIT) for one year before and three months after surgery. The postoperative clinical assessment demonstrated significant improvement of neurological symptoms and reduction of daily L-dopa dosage.

Bilateral incipient germ cell tumours of the testis in the incomplete testicular feminization syndrome.

The presence of bilateral incipient germ cell tumours in the testes of two cases of the incomplete testicular feminization syndrome (TFS) is reported and found to resemble that occurring in the testes of infertile men. Both the nature and nomenclature of the lesion is discussed, as is its relevance in the early diagnosis and improved therapy of testicular tumours, which occur frequently in TFS. Suggestions are made for a more complete postpubertal surveillance in these patients, including assay of tumour markers and bilateral biopsies in cases of complete TFS. In this condition the removal of the testes is usually delayed until the twenties when total feminization is achieved, thus increasing the chances of tumour development.
