Adult presentation of spinal dysraphism and tandem diastematomyelia.

BACKGROUND CONTEXT: Diastematomyelia is a split-cord malformation often accompanied by other cord or column anomalies. PURPOSE: To report on an adult patient with diastematomyelia and discuss the embryological basis and related developmental sequelae of this split-cord malformation. STUDY DESIGN: Case report. METHODS: A summary of the management of a 54-year-old woman with recent clinical symptomatology related to an undiagnosed split-cord malformation is presented with accompanying literature review. RESULTS: A rare adult presentation of diastematomyelia with accompanying intradural extramedullary epidermoid tumor was repaired with resection of the soft-tissue mass and excision of the fibro-osseous septum. CONCLUSION: Initial presentation of diastematomyelia is rarely seen in adults; accompanying pathology includes scoliosis, tethered cord, and intradural tumors. Effective treatment involves identification of the primary pathology.     

Evaluation of specialized laparoscopic suturing and tying devices.

BACKGROUND: Laparoscopic suturing and tying constitute advanced minimally invasive surgery skills. Developing proficiency in the standard methods with needle drivers is often an arduous process. Recent advances in laparoscopic instrumentations has allowed for easier methods of suturing and tying. This study investigated the hypothesis that the use of a specialized suturing device and a specialized tying device allows inexperienced medical students to suture and tie laparoscopically. METHODS: Preclinical medical students who had not received any training in open or laparoscopic surgery were included in this investigation. Each student was given a 5-minute demonstration of a specialized suturing device and a specialized tying device. The medical students were not allowed to deploy either device before actual use. After the demonstration, each student was given the device to use in a porcine model. Times were recorded and a subjective grade was given for each student. RESULTS: Twenty medical students were involved in this study. All medical students were able to complete the task of suturing and tying. The average time to suture was 104.6 seconds and the average time to tying was 31.2 seconds. The average subjective performance grade was 90 (out of 100). CONCLUSION: Specialized devices are easy to learn and use for laparoscopic suturing and tying with minimal instruction even for inexperienced medical students. Even surgeons who are not well versed in laparoscopic surgery should be able to suture and tie with certain laparoscopic instruments.     

Comparison between two valsalva techniques for improvement of hypopharyngeal nasendoscopy: a preliminary communication

Objective: To compare the nasal valsalva with the trumpet manoeuvre and anterior neck skin traction as aids to nasendoscopic examination of the hypopharynx. Design: Randomised, controlled comparison of examination techniques. Setting: Single tertiary referral centre. Participants: Twenty‐six adult patients requiring hypopharyngeal nasendoscopic examination were recruited. Patients were examined with both techniques in a randomised order that was recorded to video cassette. Main Outcome Measures: Blinded assessment of the percentage visualisation of the pyriform fossae, post‐cricoid and upper oesophageal sphincter was carried out by three consultant otolaryngologists independently. Results: Mean percentage scores (and 95% confidence intervals) for nasal valsalva versus trumpet manoeuvre for the three consultants, respectively, were as follows: right pyriform fossa: 77(68, 87) versus 80(71, 91), 61(55, 66) versus 60(54, 66), 46(38, 54) versus 45(37, 54); left pyriform fossa: 76(65, 87) versus 80(69, 91), 59(53, 64) versus 55(49, 61), 42(35, 49) versus 42(35, 50); post‐cricoid: 55(44, 67) versus 59(47, 71), 53(46, 60) versus 53(46, 60), 32(25, 39) versus 32(25, 39); upper oesophageal sphincter: 11(1, 21) versus 21(11, 31), 15(9, 21) versus 20(14, 26), 4(0, 8) versus 7(3, 11). No significant difference was found between the two techniques at any subsite. Individual differences were noted in a minority of patients where one or other technique gave a clearly improved view. Conclusions: The nasal valsalva and the trumpet manoeuvre with anterior neck skin traction are complementary techniques for improving the view of the hypopharynx.     

Clinical profile of trichotillomania.

Twenty-four cases of trichotillomania attending psychiatry outpatient department and child guidance clinic at Kalawati Saran Children's and Smt Sucheta Kriplani Hospitals over a period of 2 years from July, 1985 to November 1987 were studied. Females (66.7%) outnumbered the males (33.3%). Majority of cases belonged to age group 6-10 years (54.2%) and nuclear family (68.5%). Nail-biting (25.0%) was the commonest associated neurotic trait, followed by enuresis (20.9%), temper-tantrum (12.5%), etc. A past history of hysterical fits and neurotic depression was found in 3 cases (12.5%) and 2 cases (8.3%) respectively. Family history of neurosis was seen in mothers and fathers of 20.9% and 12.5% cases respectively. Trichobezoars and trichophytobezoars were found in 6 cases (25.0%) and 3 cases (12.5%) respectively. Majority of patients of trichobezoars presented with vague complaints like heaviness in the stomach (55.6%), inability to gain weight (44.4%), etc, while 22.2% cases were asymptomatic and detected only on screening.     

Treatment of dual diagnosis patients: A relapse prevention group approach

The authors describe the successful use of an adjunctive group psychotherapy for substance-abusing patients with major psychiatric disorders (bipolar, schizophrenia, schizoaffective, psychotic depression, and atypical psychosis). The group utilizes a psychoeducational approach that focuses on substance abuse causes and consequences, principles of recovery, and relapse prevention strategies. Eight patients with prolonged histories of abuse of cocaine, alcohol, marijuana, or other drugs were enrolled in this weekly group treatment at a community mental health center drug treatment program, while continuing in treatment with their current case manager or primary therapist. Six of the eight patients achieved periods of stable abstinence, documented by self-report, urine toxicology screens, continued group attendance, and improved social functioning. Case examples are utilized to illustrate the group process.     

Prophylactic antiangiogenic tumor treatment

Complementary antitumor treatments are required to increase the cure rate achieved by surgery and/or radiotherapy by avoiding future recurrences and metastases. The growth of most solid tumors, particularly carcinomas, depends upon the simultaneous development of internal tumor vasculature to allow the proliferation of tumor cells. Inhibition of tumor vascularization is an indirect means of limiting tumor expansion. Daily administration of cortisone and maltose tetrapalmitate (MTP) abolished growth of implanted syngeneic C3HBA mammary tumor. Gross and macroscopic examination of these tumors revealed that tumor growth was prevented. Histological examination demonstrated lack of vascularization within the neoplastic tissue. We believe that this combination in an appropriate form could provide a prophylactic treatment regimen after conventional antitumor treatments in humans.     

Sarcoid Myelopathy

A 45-year-old woman with history of iritis, uveitis, and sarcoidosis of the skin presented with a subacute cervical myelopathy. Magnetic resonance imaging (MRI) ;howed patchy, multifocal, gadoliniumenhancing intramedullary lesions of the spinal cord, and extramedullary lesions of the basal cisterns and fourth ventricle. Symptoms and MRI abnormalities were improved within 1 month of corticosteroid therapy.
