Syringe liposculpture: A two-year experience

Syringe liposcupture is a method that combines two relatively new techniques of plastic surgery: syringe liposuction and fat grafting. We can reshape the face and the body by removing localized fat deposits and reinjecting this fat where needed. When we do not reinject, we call the technique reduction liposculpture. In 1989 we introduced a new technique—superficial syringe liposculpture—to treat patients with flaccid skin, superficial irregularities or depressions, cellulite, and liposuction sequelae. The technique combines syringe liposculpture, superficial liposuction, and our method of treating skin irregularities by breaking the fibrous adherences and injecting fat superficially.

Antibodies directed at mouse IL-2-R α and β chains act in synergy to abolish T-cell proliferation in vitro and delayed type hypersensitivity reaction in vivo

The anti-mouse IL-2-R chain mAb TM-1 which, by itself, does not affect IL-2-dependent proliferation throught the high affinity mouse IL-2 receptor, was shown to cooperate in a synergistic way with a set of anti-IL-2-R chain mAbs both in vitro and in vivo. In vitro, when associated at equimolar concentrations, the TM-1/anti- mAb association was four to ten times more efficient at inhibiting the proliferation of the CTL-L2 cell line than was a similar concentration of anti- mAb alone. In addition, a bispecific antibody in which a Fab' fragment of TM-1 was covalently linked to a Fab' fragment of one of the anti- mAb (5A2) was shown to be as efficient as the TM-1/5A2 association. The association of TM-1 with 5A2 was also tested in vivo in a sheep red blood cell-induced delayed type hypersensitivity (DTH) model. TM-1 which, by itself, had no effect on DTH, induced a two- to threefold decrease in the doses of 5A2 required to suppress this cell-mediated immune reaction.     

63. Dauer und Wandel im ärztlichen Ethos

Zusammenfassung Der Vortrag entwickelt zuerst einen allgemeinen Begriff des Ethos [1] und Kategorien zur Erfassung seiner Strukturen [2]. Das klassische hippokratische Ethos zeigt sich dann als Entwurf, welcher ärztliches Handeln als Sache eines, durch praktisch Wissenschaft orientierten Standes im Dienst des privaten Wohls des Patienten normiert [3]. Der Wille, im Wandel der Bedingungen ärztlicher Praxis die Substanz dieses Ethos auf Dauer zu stellen, erfordert a) gegen das Mißverständnis der Medizin als theoretischer Naturwissenschaft die Besinnung aufihren praktischen Charakter, b) gegen die Ausweitung einer bloß sozialen Zielsetzung die Anerkenntnis der Maßstäblichkeit des privaten Verhältnisses zum Patienten, c) gegen die technologisch bedingte Entpersönlichung eine Orientierung am Gesamt der Bedürfnisse des Patienten.     

PTSD among vietnam veterans: An early look at treatment outcome using direct therapeutic exposure

Vietnam combat veteran inpatients were evaluated after being treated in a PTSD special treatment unit. Selected pretreatment measures that included mental and physical problems, combat variables, PTSD symptoms, and the standard MMPI scales found no clinically meaningful differences between a group that was found to be successes and another group found to be failures, based on predetermined cutoff scores on the VETS scale, a reliable outcome measure for veteran patients. At 3 months post-therapy, a significantly greater number of subjects treated with Direct Therapeutic Exposure (DTE) (flooding therapy) as compared to another group treated with a more conventional individual therapy, were identified as successes as opposed to failures, based on the VETs scale. Also, the number of failures was greater for those treated with the more conventional therapy and the number of successess was greater for those treated with DTE, when compared to all other subjects in the sample. These preliminary results were interpreted as indicating that DTE, when offered as part of an inpatient milieu, shows promise as an effective treatment for chronic/severe combat veteran PTSD sufferers.     

Anterior lumbar interbody fusion with carbon fiber cage loaded with bioceramics and platelet-rich plasma. An experimental study on pigs

Platelet-rich plasma (PRP) is an autogenous source of growth factor and has been shown to enhance bone healing both in clinical and experimental studies. PRP in combination with porous hydroxyapatite has been shown to increase the bone ingrowth in a bone chamber rat model. The present study investigated whether the combination of beta tricalcium phosphate (-TCP) and PRP may enhance spinal fusion in a controlled animal study. Ten Danish Landrace pigs were used as a spinal fusion model. Immediately prior to the surgery, 55 ml blood was collected from each pig for processing PRP. Three-level anterior lumbar interbody fusion was performed with carbon fiber cages and staples on each pig. Autogenous bone graft, -TCP, and -TCP loaded with PRP were randomly assigned to each level. Pigs were killed at the end of the third month. Fusion was evaluated by radiographs, CT scanning, and histomorphometric analysis. All ten pigs survived the surgery. Platelet concentration increased 4.4-fold after processing. Radiograph examination showed 70% (7/10) fusion rate in the autograft level. All the levels with -TCP+PRP showed partial fusion, while -TCP alone levels had six partial fusions and four non-fusions (P=0.08). CT evaluation of fusion rate demonstrated fusion in 50% (5/10) of the autograft levels. Only partial fusion was seen at -TCP levels and -TCP+PRP levels. Histomorphometric evaluation found no difference between -TCP and -TCP+PRP levels on new bone volume, remaining -TCP particles, and bone marrow and fibrous tissue volume, while the same parameters differ significantly when compared with autogenous bone graft levels. We concluded from our results in pigs that the PRP of the concentration we used did not improve the bone-forming capacity of -TCP biomaterial in anterior spine fusion. Both -TCP and -TCP+PRP had poorer radiological and histological outcomes than that of autograft after 3 months.     

Vertical lengthening of the unilateral cleft lip after a triangular flap repair

Summary A triangular flap repair for unilateral cleft lip is stated to have the potential problem of creating a lip that is too long. Although preoperative measurements were performed with calipers, the gap created in the medial segment was directly measured during the procedure, in order to determine the size of the flap more precisely. Ninety patients with complete unilateral cleft lips underwent a triangular flap repair using this method. The symmetry of the Cupid's bow was evaluated at a follow-up period averaging between six years and three months. Sixty-two lips obtained symmetry and the remaining 28 cases showed a lip which was too long; none of the lips were too short. The comparison between 27 primary palate clefts (UCLA) and 63 primary and secondary palate clefts (UCLP) showed no significant difference in the surgical result. The preoperative shortness of the lip on the cleft side was significantly greater in the too long group (5.01 ± 0.95 mm) than in the symmetry group (4.40 ± 0.87 mm). The width of the flap used was significantly larger in the too long group (3.76 ± 0.79 mm) than in the symmetry group (3.42 ± 0.69 mm). The triangular flap repair with intraoperative measurements is considered to be beneficial, although preoperative measurements provide an optimal design in most cases. It is suggested that the use of a wider triangular flap results in a lip which tends to be too long in spite of the preoperative shortness on the cleft side.

Diagnostic approach in instability and irritative state of a “lumbar motion segment” following disc surgery—Failed back surgery syndrome

Summary A diagnostic protocol for patients with suspected instability and irritative state of a lumbar motion segment following lumbar disc surgery is presented and the results of internal fixation are analyzed.In this group of patients the clinical picture and physical signs may be quite distinct and suggestive of instability and irritation of a lumbar motion segment, however, in isolation, they do not allow to decide upon surgery. Radiological studies favour a decision for surgery only in cases with an obvious instability of a motion segment. Anaesthethizing the articular nerves permits localization of the irritable segment and non-surgical therapeutic decisions (thermocoagulation) can only be taken in cases of an isolated facet-syndrome when instability has been ruled out. The trial plaster jacket holds the most important position with respect to the indication for internal fixation as demonstrated by the conformity of the results of the plaster jacket and the results of surgery.After internal stabilization excellent, good, satisfactory and moderate results were obtained in 20, 3, 1 and 1 patients, respectively.The German term Bewegungssegment comprises all parts which are involved in the movements of one vertebral segment, i.g. disc, facet joints, ligaments and related muscles.     

Serial and superficial suction for steatopygia (Hottentot Bustle)

Steatopygia, from the Greek steato meaning fat and pygia meaning buttocks, is defined as excessive fat of the buttocks, usually seen in women and sometimes called Hottentot Bustle because it was commonly seen in the Hottentot people of southern Africa. This affliction is characterized by protrusion and excessive fatness of just the buttocks region. Our patient was not particularly overweight (166 lb) and had a reasonably thin waist and legs. However, her buttocks were so protruding as to appear to have been from a completely different person. She wore only full skirts and could never wear jeans or pants of any kind. By using both superficial and deep serial suction techniques we were able to remove 12.5 L of subcutaneous fat over a two-year period without hospitalization or exogenous transfusion. The superficial technique improved skin retraction.     

Use of a pericardial fat pad flap for preventing bronchopleural fistula: An experimental study focusing on the angiogenesis and cytokine production of the fat pad

An experimental study was conducted to determine whether pericardial fat tissue could induce neovascularization and produce cytokines related to tissue repair. Neovascularization was examined using chick chorioallantoic membranes. Pieces of pericardial fat tissue, omentum, and intercostal muscle were individually placed on a number of chorioallantoic membranes and neovascularization induced by each material was assayed 6 days after the implantation. The intensity of neovascularization was in the order of pericardial fat omentum > muscle. Cytokines, such as interleukin 1 (IL-1) and , tumor necrosis factor- (TNF), interferon- (IFN-), and interleukin 6 (IL-6) were assayed in a culture supernatant of pericardial fat tissue. The latter was obtained 24h after the addition of lipopolysaccharide (LPS) following various incubation times. All cytokines other than IFN are known to play a part in tissue repair, whereas IFN is negatively related to tissue repair because it inhibits fibroblast growth. The pericardial fat tissue incubated with LPS produced a certain amount of IL-1 on day 1, and TNF on days 1 and 8, whereafter these values decreased to an undetectable level. Irrespective of the addition of LPS, a large amount of IL-6 was observed in the supernatant of pericardial fat tissue and it was detectable until day 29. On the contrary, INF was not detected at any assay time. These observations suggest that a pericardial fat pad flap could possibly be beneficial in the prevention of bronchopleural fistula after pulmonary resection.     

Effects of calcium and temperature on tension in isolated canine coronary artery

The effects of calcium and temperature on the tension of isolated canine coronary arterial strips were studied.In 20mEq·l ^–1 K solution, the tension was significantly increased from 0mg with 0mEq·l ^–1 Ca to 33 ± 18mg with 0.2mEq·l ^–1 Ca at 37°C, from –40 ± 18mg with 0mEq·l ^–1 Ca to –17 ± 11mg with 0.2mEq·l ^–1 Ca at 30°C, from –77 ± 19mg with 0mEq·l ^–1 Ca to –52 ± 17mEq·l ^–1 with 1mEq·l ^–1 Ca at 25°C, from –88 ± 13mg with 0mEq·l ^–1 Ca to –41 ± 18mg with 2mEq·l ^–1 Ca at 20°C, from –125 ± 16mg with 0mEq·l ^–1 Ca to –116 ± 13mg with 2mEq·l ^–1 Ca at 15°C. Ca higher than 0.2mEq·l ^–1 produced a dose-dependent increase in tension between 37°C and 15°C. In spite of the presence of 4mEq·l ^–1 Ca, the development of tension was strongly supressed by lowering the temperature below 20°C, and completely inhibited at 10°C. The rate of a decrease in tension caused by cooling was about 5.5mg·°C^–1.This study demonstrated that Ca²⁺ produced a dose-dependent increase in tension in high-K solution, which was suppressed as the temperature was lowered.(Yoshida K, Fujii Y, Ina H, et al.: Effects of calcium and temperature on tension in isolated canine coronary artery.

Differential expression of transforming growth factor-β1 and β3 as well as C-FOS mRNA in normal human prostate,benign prostatic hyperplasia and prostatic cancer

Summary The discrepancy between the incidence of latent prostate cancer and that of clinically overt carcinoma suggests that there can be different courses in the biological progression of prostate cancer. As this cancer is detected increasingly at an infraclinical stage, markers are needed to indicate which lesions will progress and lead to the patient's death. To investigate the possibility that specific growth factors and/or proto-oncogenes are expressed differentially, we measured mRNA levels of transforming growth factors 1 (TGF-1), TGF-2 and TGF-3 and of the c-fos and c-jun oncogenes by Northern blotting in normal prostate, benign prostatic hyperplasia (BPH) and prostate cancer. Our data demonstrate that expression of TGF-1 increased, whereas that of TGF-3 fell to an almost undetectable level in carcinoma. Expression of c-fos followed the TGF-1 pattern, whereas no difference could be seen in c-jun expression in cancer as compared with BPH and normal prostate. The differential expression of TGF-1, TGF-3 and c-fos could possibly be used to improve the characterisation of prostate cancer. Long-term follow-up of patients may indicate whether mRNA levels of these growth factors and oncogenes correlate clinically and whether they can be used as markers for progression in human prostate cancer.     

Differentiation of pancreatic ductal carcinoma cells associated with selective expression of protein kinase C isoforms

Background: The signal transduction pathways important in regulating the growth and differentiation of malignant cells are poorly understood. Recent evidence has implicated activation of the protein kinase C (PKC) family of signaling proteins in pancreatic carcinoma during cytokine-induced cytostasis and differentiation. Methods: A human pancreatic adenocarcinoma (HPAC) cell line was exposed to tumor necrosis factor- (TNF-; 40 ng/ml) for 6 days. Cytostasis and viability were confirmed by daily MTT [(3(4,5)-dimethyl-thiazol-2-yl) 2,5-diphenyl-tetrazolium bromide] and trypan exclusion assay. Protein fractions were isolated daily and subjected to immunoblot analysis for the normal (terminally differentiated) pancreatic ductal cell marker carbonic anhydrase II (CA II) as well as specific PKC isoforms (, , , , and). Results: Growth arrest occurred in HPAC cells after exposure to TNF- for 48 h, with viability maintained above 90% throughout the 6-day time course. CA II immunoreactivity was not detected in untreated controls but appeared after 2 days of TNF- exposure, peaking on day 6. Concurrently, TNF- induced the selective downregulation of PKC-, whereas PKC- levels increased. PKC- and PKC- immunoreactivity did not change. The atypical PKC- isoform developed a doublet banding pattern in response to TNF-, although overall PKC- levels did not change. Conclusions: TNF--induced growth arrest and differentiation in HPAC cells is associated with the selective downregulation of PKC- and upregulation of PKC-.Presented at the 48th Annual Cancer Symposium of The Society of Surgical Oncology, Boston, Massachusetts, March 23–26, 1995.     

The fat nose

The fat or sebaceous nose,^* with its thick, bulky skin filled with prominent sebaceous glands, is often improved surgically only by the use of external excisions of this tissue. The author describes several variations of this technique with representative cases.     

Premature craniosynostosis a retrospective analysis of a series of 52 cases

Summary A retrospective analysis of a consecutive series of 52 cases with premature craniosynostosis is presented.Excellent functional, cosmetic, and social results could be achieved by resection of prematurely fused sutures and the creation of artificial growth sutures. Pronounced skull deformities have been corrected using the basket handle, the visor plasty, and the T-bone techniques or a combination of several of these skull form correction techniques. The surgical correction of the skull base by the frontal advancement technique in combination with orbitotomy was only necessary in 2 of our cases and could have been considered in 2 additional cases viewed retrospectively.Our results support the hypothesis that the primary cause of skull deformity is the premature closure of vault sutures and not a primary deformity of the skull base.     

The N-Methyl-D-aspartate (NMDA) receptor antagonist dizocilpine (MK-801) suppresses enfturane-induced opisthotonus in mice

We determined whether enflurane-induced opisthotonus in ddN mice is mediated by N-methyl-D-aspartate (NMDA) receptor using NMDA receptor antagonists dizocilpine (MK-801) and ketamine. Animals were given intraperitoneal injections of 0.2ml saline (control), 2.5 or 5.0mg·kg^–1 dizocilpine in saline, or 20 or 40mg·kg^–1 ketamine is saline 20min prior to exposure to 2.0% enflurane. Incidence of opisthotonus measured during exposure to enflurane for 20min was 49% (n = 51) in saline (control) group, 6.7 (P 0.01 vs control, n = 30) and 15.0% (P 0.01, n = 40) in 2.5 and 5.0mg·kg^–1 dizocilpine group, respectively, and 43.9 (NS, n = 41) and 40.0% (NS, n = 40) in 20 and 40mg·kg^–1 ketamine group, respectively. These results strongly suggest that enflurane-induced opisthotonus is mediated by NMDA receptor. Ketamine failed to suppress significantly due to possibly small dosages. Further, dizocilpine itself produced severe seizures during preenflurane period (30.0 and 40.0% in 2.5 and 5.0mg·kg^–1, respectively), which may be a novel finding.(Komatsu H, Nogaya J, Anabuki D, et al.: The N-methyl-D-aspartate (NMDA) receptor antagonist dizocilpine (MK-801) suppresses enflurane-induced opisthotonus in mice.

Guidelines for a short-term therapy of a torture depression

Psychotherapeutic work with torture traumas and their aftereffects are made difficult through a number of factors. Six guiding principles are presented in this publication through which make it possible to influence the actual symptomatology within the limits of the short therapy, even under difficult conditions. Creative images, described in detail as process fantasies, are the focus of this short therapy. Situative experiences in the treatment process are not interpreted with reference to the subject or the concrete trauma. This leads to the intra-psychic patterns being unlinked from traumatic torture experience patterns. With the aid of a model which discusses the torture as a superinfection with psychogenic violence-viruses, the penetration and resistance to therapy towards the torture trauma can be illuminated so that a differentiation of social and psychological factors of the torture experience is made possible.     

Methylated β-cyclodextrins are able to improve the nasal absorption of salmon calcitonin

The absorption enhancing effect of methylated -cyclodextrins on the nasal absorption of salmon calcitonin (sCT) was studied in rats and rabbits. The nasal absorption of sCT following administration without additives was low in both species. The absorption in rats could be largely improved by coadministration of cyclodextrins as apparent from the effect on serum calcium concentrations. Trimethyl--cyclodextrin (TMCD), at a concentration of 5% (w/v), was the least potent enhancer. Randomly methylated--cyclodextrin (RMCD) and dimethyl--cyclodextrin (DMCD), all at a concentration of 5% (w/v), were almost equally effective in decreasing serum calcium levels, and the hypocalcemic responses were similar to those of i.v. and s.c. injected sCT. Absorption enhancement was already achieved with 1% DMCD added to the nasal formulations. In rabbits, only the effect of DMCD on the nasal sCT absorption was investigated. A total serum calcium decrement in 4 hours of 9.4±3.9% (mean±SD) was observed following nasal administration of 12.6 IU/kg sCT with 5% DMCD, comparable to that of i.v.-injected sCT. In conclusion, the methylated cyclodextrins DMCD and RMCD are suitable absorption enhancers for nasal sCT administration, which is expected to have a clinical impact on the therapy with calcitonin.     

Suppression of parathyroid hormone secretion in CAPD patients by intraperitoneal administration of Maxacalcitol

Background Maxacalcitol (22-oxacalcitriol; OCT) is a novel vitamin D analogue. In previous clinical studies, OCT was administered three times a week to hemodialysis patients with refractory secondary hyperparathyroidism (2HPT), in whom it acted by inhibiting parathyroid hormone secretion, as well as causing mildly elevated serum calcium. However, intravenous injection of OCT, which requires frequent visits to the outpatient clinic, degrades the quality of life of patients with continuous ambulatory peritoneal dialysis (CAPD) who otherwise visit the clinic only once or twice per month. In the present study, we investigated whether transperitoneal absorption of OCT inhibited intact parathyroid hormone (i-PTH) in CAPD patients when the OCT was added to the peritoneal dialysis fluid.Methods Peritoneal dialysis fluid containing 20µg of OCT was injected into the peritoneal cavity of five CAPD patients. The serum and peritoneal fluid levels of OCT, i-PTH, calcium, and phosphate were measured before and after treatment.Results The mean concentration of OCT in peritoneal dialysis fluid rapidly decreased, from 25268.0pg/ml at 0h to 1694.0pg/ml at 2h and 44.9pg/ml at 4h. In contrast, the mean serum OCT level increased from the pretreatment level, which was below the detection limit of the assay, to 656.0pg/ml at 0.5h and a peak of 759.0pg/ml at 1h, and thereafter gradually decreased, to 713.8pg/ml at 2h and 555.8pg/ml at 4h. Mean i-PTH significantly decreased, to 83.9% of the baseline level, at 1h (P < 0.05) and thereafter stayed at around 90%. No consistent trends in calcium and phosphate levels were observed in the five patients.Conclusions By injecting OCT into the peritoneal cavity, i-PTH levels could be significantly decreased. These findings indicate the therapeutic efficacy of intraperitoneal administration of OCT for CAPD patients.
