The selected response procedure: a variation on Appelbaum's altered atmosphere procedure for the Rorschach.

This article introduces the Selected Response Procedure, which is a supplementary technique for expanding the scope of the Rorschach test. The procedure is conducted as follows: After the standard administration of the Rorschach test, patients are asked to look through all of the cards a second time and select one more response from any card of their choice. A rationale for this procedure is developed through a comparison to another supplementary Rorschach technique, the Altered Atmosphere Procedure. The importance of understanding the selected response within a theoretical framework, as well as the clinical context of each selected response, is highlighted by a clinical example using object relations theory. Finally, a number of didactic questions are offered as potential ways to query the possible meaning of selected responses.

Comparison of several regression procedures for method comparison studies and determination of sample sizes. Application of linear regression procedures for method comparison studies in Clinical Chemistry, Part II.

In part I of this series (H. Passing & W. Bablok (1983), J. Clin. Chem. Clin. Biochem. 21, 709-720) we described a new biometrical procedure for the evaluation of method comparison studies. In part II we now discuss its properties and compare them with those of other established procedures by means of a simulation study. We demonstrate that the reliability of the results not only depends on the sample size but also on the sampling distribution, the precision of the methods, and the concentration range covered by the samples. Linear regression and principal component procedures are either inadequate or not as reliable as our new procedure. The appropriate sample size is discussed and recommendations are given.

Toward a clinical procedure for narrowband gap detection I: a psychophysical procedure.

This paper examines a possible procedure for a clinical gap-detection test that is simple, frequency specific, and reliable. A cued yes-no method of maximum likelihood (MML) procedure was compared to an up-down three-interval, two-alternative, forced-choice procedure. Results from five trained and seven naive listeners indicate that the yes-no MML procedure yields valid and efficient estimates of narrowband gap-detection thresholds. Preliminary tests yield encouraging results.

[Ventricular tachycardia and ventricular fibrillation. Diagnostic procedure for selection of patients for non-medicamentous therapeutic procedures].

The use of nonpharmacological methods in the treatment of life-threatening ventricular tachyarrhythmias is increasing. These include surgical procedures, the application of direct and radiofrequency current for endocardial ablation, antitachycardia stimulation techniques and the implantation of cardioverter defibrillators. Each of these therapeutical procedures is characterized by its specific indication. Based on the underlying cardiac disease and the characteristics of the electrophysiological properties of the ventricular tachyarrhythmia as well as based on the specific properties of the different nonpharmacological procedures an individual therapeutical approach has to be tailored for a patient given. Primary goal is application of a nonpharmacological procedure exclusively, however, in selected cases additional administration of an anti-arrhythmic drug (decrease in tachycardia frequency in patients with implanted defibrillators, widening of the termination window in patients with antitachycardia devices) may be necessary to achieve satisfactory tachycardia control.

Gadolinium use in spine procedures for patients with allergy to iodinated contrast--experience of 127 procedures.

BACKGROUND AND PURPOSE: To review the safety and efficacy of gadolinium as a contrast agent in spine pain management procedures in patients who are at high risk for a contrast reaction and are therefore unacceptable candidates for the use of standard nonionic contrast. METHODS: We reviewed our records over a 4-year period of interlaminar and foraminal epidural steroid injections, nerve blocks, facet injections, intercostal blocks, and diskograms in the lumbar, thoracic, and cervical spine for cases in which patients had allergies that made them unsuitable candidates for standard nonionic contrast and where gadolinium was used to confirm needle tip placement before injection of medication. RESULTS: Ninety-two patients underwent 127 procedures. A spinal needle was used in all but 7 procedures. All patients were outpatients and all were discharged without complication after 20 to 45 minutes with follow-up instructions. No delayed complications were reported. Gadolinium was visualized by using portable C-arm fluoroscopy in vivo allowing for confirmation of needle tip location. For epidural steroid injection, the gadolinium dose ranged from 1 to 5 mL, nerve blocks from 0.2 to 1 mL per level, facet injections from 0.2 to 0.5 mL per level, intercostal blocks used 0.5 mL, and diskograms from 1.5 to 7.5 mL per level. The highest dose received by 1 patient was an intradiskal 15.83 mL during a 3-level diskogram. CONCLUSION: Gadolinium seems to be a safe alternative to standard nonionic contrast in spine pain management procedures in those patients considered to be at high risk for a contrast reaction.

Involutional entropion: a retrospective analysis of the Wies procedure alone or combined with a horizontal shortening procedure.

The surgical management of 95 cases of involutional entropion were reviewed to form this retrospective study. The 66 cases treated with the Wies procedure alone had a recurrence rate of 11%. The 29 cases treated with a combined procedure consisting of a Wies procedure with a lateral canthal horizontal shortening had no recurrences. All patients had a minimum of 6 months postoperative follow-up. The etiologic factors as they relate to the appropriate surgical procedures are discussed.

The Reverdin-Isham procedure for the correction of hallux abducto valgus. A distal metatarsal osteotomy procedure.

The Reverdin-Isham Procedure is a distal metatarsal osteotomy procedure that has stood the test of time and has revolutionized the correction of simple to severe hallux abducto valgus deformities. This procedure, a modification of the classic Reverdin bunionectomy, modifies the osteotomy cut of Reverdin by performing a medial wedge osteotomy through the head of the first metatarsal. In this modification, the osteotomy is performed at an oblique angle from dorsal distal to plantar proximal through the head of the first metatarsal, preserving the entire articular surface of the first metatarsal head. The result of this osteotomy places the articular surface of the first metatarsal into alignment with the shaft of the first metatarsal, thereby correcting the structural deformity of hallux abducto valgus at the first MPJ. This modification, using the advances of minimal incision surgery, is a procedure that is highly successful, permits immediate ambulation, causes minimal disability, allows early return to productive activities, and is cost effective.

Statistical comparison of blood glucose as determined by several test-strip procedures and by a hexokinase procedure.

We report a new statistical tool for comparing several dry-reagent strip procedures for whole blood glucose, which produce data in both digital and ordinal form, with results by the well-studied hexokinase-glucose-6-phosphate dehydrogenase procedure coupled to NAD+-NADH. Our use of "ordinal comparison unit" allows for a more equitable comparison of such data. These strip procedures produce biases of -2.21 to 1.74 ordinal comparison units over the range of glucose values corresponding to hypoglycemia and hyperglycemia, as compared with results by the hexokinase procedure, but they are essentially equivalent when compared with each other.

Comparison of D-value accuracy among Limited Spearman-Karber Procedure, Stumbo-Murphy Cochran Procedure (SMCP) and Limited SMCP.

The Limited Spearman-Karber Procedure (LSKP) and Stumbo Murphy and Cochran Procedure (SMCP) are procedures to determine D-value in the Most Probable Number method (MPN). International Organization for Standardization (ISO)/Technical Committee 198/Working Group 4 contributing for the preparation of documents on biological indicator has adopted only LSKP in MPN. SMCP has been rejected due to the reason of inaccuracy without any scientific proof. Therefore, in order to confirm whether this is scientifically correct or not, Japanese delegates decide to compare both methods in simulation and experimental procedures using biological indicator and biological indicator evaluator resistometer. The result indicated that SMCP with some restrictions was not always inferior to LSKP and gave identical results.

Partial gastric resection for peptic ulcer--comparison of the effect of variant reconstructive procedures on gastric emptying, gastric acid secretion and gastrin release in the early postoperative period II. Billroth-I gastroduodenostomy and comparison versus gastroenteroanastomotic procedures.

Gastric emptying (GE) of a radiolabelled solid meal, gastric acid secretion and gastrin release was measured before and/or by 91/2 weeks postoperatively in 12 patients with partial gastric resection supplied with Billroth-I gastroduodenoanastomosis and usually (n = 10) with truncal vagotomy [B-1+(VT))]. The results obtained were compared to those derived from another study involving 14 patients with partial gastric resection supplied with a gastroenterostomy (of Roux-en-Y type in 11, and Billroth-II type in 3 subjects) and truncal vagotomy [Roux(B-II)+VT]. The B-I+(VT) procedure affected significantly neither the overall GE (the median T1/2 was 75 min before and 95 min after the surgery) nor the GE pattern-the median curve shape parameter S was 0.73 before and 1.07 after the operation. The basal and pentagastrin-stimulated gastric acid secretion was reduced by an average of 79% (from 8.6 +/- 2.5 to 1.8 +/- 0.5 mmol h-1, p < 0.05) and 77% (from 22.0 +/- 2.8 to 5.0 +/- 1.5 mmol h-1, p < 0.05) after the B-I+(VT), respectively. Moreover, after the B-I+(VT) a decrease in the fasted serum gastric concentration (78.3 +/- 17.0 before vs 62.4 +/- 6.9 ng l-1 after the surgery) and in the postprandial gastrin release (AUC0-120: 11716 +/- 2482 ng l-1 min before vs 9753 +/- 1183 ng l-1 min after the surgery) was found; the relevant differences were, however, statistically not significant. In patients with a preoperatively normal GE, a markedly slowed GE (T1/2 above the limit of the mean T1/2 +2SD in healthy controls) was found in 5 out of 8 (62%) patients after the Roux-en-Y procedure, and only in 1 out of 7 (14%) patients after the B-I or B-II procedure. With regard to the postoperative data, the Roux (B-II)+VT resulted in lower gastric acid secretion and gastrin release than the B-I+(VT) procedure but the relevant differences were statistically not significant.

Hallux valgus: soft tissue procedure versus bony procedure.

Hallux valgus is one of the most common fore-foot problem in civilized populations. 49 feet of 33 cases, 8 males and 25 females with an average age of 50 years old, were treated surgically from 1987 to 1992 for hallux valgus and followed up for an average of 47.8 months, comprising 20 feet with McBride's soft tissue procedure and 29 feet of Mitchell metatarsal osteotomy. The clinical criteria for follow up included pain relief, cosmetic out look, shoe wearing comfort, metatarsophalangeal motion etc. 87.5% of the cases in the McBride's group and 95% of the cases in the Mitchell group were satisfied with the clinical results. The immediate post-operative metatarsophalangeal (MP) angle and intermetatarsal (IM) angle were both well corrected, but there was a significantly higher recurrence rate of hallux valgus in the group with the McBride's procedure (P < 0.05). One case in the McBride's group had the complication of hallux varus and one case from the Mitchell group had delayed union. The Mitchell bony procedure has a more stable result compared to the McBride's soft tissue procedure for the correction of moderate hallux valgus, and the modified Mitchell osteotomy is less invasive, easier to perform, easier to care for, and has more satisfactory long-term results.

New reconstructive procedure after intestinal resection for Crohn's disease: modified side-to-side isoperistaltic anastomosis with double Heineke-Mikulicz procedure.

Although side-to-side isoperistaltic anastomosis is a useful strictureplasty technique when long segments of intestinal stenosis complicate Crohn's disease, concerns have been raised regarding disease recurrence adjacent to the anastomosis. We performed side-to-side isoperistaltic anastomosis without spatulated intestinal ends as a method of reconstruction after intestinal resection for Crohn's disease; both intestinal ends were transversely closed like a Heineke-Mikulicz-type strictureplasty. With this procedure, the luminal diameter proximal and distal to the anastomosis became wider than the original diameter of the intestine. This new procedure, which we refer to as the "modified side-to-side isoperistaltic anastomosis with double Heineke-Mikulicz procedure" could become an alternative operation after intestinal resection in persons with Crohn's disease, although long-term outcome analysis is necessary.

Complications of laparoscopic procedures in urology: experience with 2,407 procedures at 4 German centers.

PURPOSE: The 4 most active centers of the laparoscopy working group of the German Urologic Association collected data about the complications associated with laparoscopic surgery in urology. MATERIALS AND METHODS: At 4 centers 2,407 laparoscopies or retroperitoneoscopies were performed as of May 1998, including 776 for varicocelectomy, 259 for cryptorchidism, 481 for pelvic lymph node dissection, 351 for nephrectomy/heminephrectomy renal pathology, 139 for renal cyst resection, 58 for ureteral procedures, 44 for adrenalectomy, 41 for nephropexy, 41 for lymphocele fenestration, 40 for retroperitoneal para-aortic lymphadenectomy and 187 for other operations. The complications were evaluated, listed according to the anatomical specificity and grouped with respect to the surgical step during laparoscopy. RESULTS: A total of 107 complications (4.4%) occurred. The re-intervention rate was 0.8% and the mortality rate was 0.08%. The complication rate depended on the difficulty of the procedure and averaged 1.0, 3.9 and 9.2%, respectively, for easy, difficult and very difficult operations. The majority were vascular injuries (1.7%) and visceral lesions (1.1%) followed by complications of healing and infection (0.8%). Only 0.2% of complications was associated with the access technique (trocar insertion), whereas most occurred during dissection (2.9%). The complication rate was 13.3% for the first 100 procedures and subsequently averaged 3.6%. CONCLUSIONS: Critical documentation of experience from several institutions, especially for an analysis of complications of urological laparoscopy, is important for the development of this surgical technique. The overall complication rate is comparable to other specialties. Future technical developments in trocar insertion, tissue dissection and control of bleeding with our improved training program will further reduce the complication rate.

[Partial left ventriculectomy (Batista-procedure) as an alternative to transplantation and as a rescue procedure].

Partial left ventriculectomy (Batista operation) is one of several surgical options for the treatment of end-stage heart disease. In a 17-year-old patient who could not be accepted as a candidate for heart transplantation, this procedure was performed as an acute rescue procedure in conjunction with reduction of the left ventricle, single-stitch reconstruction of the mitral valve and removal of a ventricular thrombus. Following temporary dependence on mechanical circulatory support the patient was transferred to his own country. The clinical experience is discussed, including aspects of the surgical technique, postoperative complications, indication, relevance of mitral reconstruction and rhythm problems. It is concluded that partial left ventriculectomy can be used to treat end-stage dilated cardiomyopathy, even as an emergency operation. Further studies and experience are needed to clarify the long-term effects and clinical limitations of the procedure.

"Madame Butterfly" procedure: combined cheek and lateral canthal suspension procedure for post-blepharoplasty, "round eye," and lower eyelid retraction.

The most common complication of lower eyelid blepharoplasty is eyelid retraction ("scleral show") of the lateral one-third of the lower eyelid, with associated rounding and inferior displacement of the lateral canthus. A procedure in which the middle lamellar cicatrix is lysed, the lateral canthus reconstructed, and the cheek elevated to provide additional vertical anterior lamellar skin is described. Skin grafting is often aesthetically poor in the lower eyelid and is unacceptable in the upper eyelid. This new procedure may be used to elevate the lower eyelid rather than lower the upper eyelid in cases of post-blepharoplasty lagophthalmos with exposure keratopathy. Thus, the procedure offers cosmetic and functional repair, without the use of skin grafts, for the patient who would normally need upper and lower eyelid skin grafting.

[New surgical procedure for patients with dilated heart and end-stage cardiac failure (Batista procedure)].

A 53-year-old man with dilated cardiomyopathy underwent left ventriculoplasty (Batista procedure), a new surgical procedure, which reduces ventricular volume to improve left ventricular function. Left ventricular ejection fraction increased from 19.7% to 43.7%. Unfortunately, he died of pneumonia 12 days after surgery. This is the first such procedure in a human in Japan.

[Surgical treatment for congenital motive defect nystagmus by the parks (5, 6, 7, 8mm) procedure or the augmented Parks procedure].

PURPOSE: The purpose of the surgical treatment for patients with congenital motive detect nystagmus was to correct deviation of the eye and the head tilt, to improve vision and eliminate nystagmus. METHODS: 19 patients underwent the Parks (5, 6, 7, 8mm) or the augmented Parks procedure from 1987 to 1994. For patients with abnormal head turn > or = 30 degrees, We used a 40-60% augmented Parks procedure. RESULTS: A follow up of 19 patients ofr an average of 22 months revealed a marked improvemtnts. After operation, the head turn was decreased form 30.5 degrees to 4.9 degrees, the intensity of nystagmus was decreased from 36.0 to 9.7, 21 eyes (55.3%) of 19 patients improved by two or more lines of Snellen visual acuity. CONCLUSIONS: The Parks (5, 6, 7, 8mm) and the augmented Parks (5, 6, 7, 8mm) procedure produce a marked correction for congenital motive defect nystagmus.
