Alternatives to thumb replantation   总被引:1,自引:0,他引:1  
Heitmann C  Levin LS 《Plastic and reconstructive surgery》2002,110(6):1492-503; quiz 1504-5
LEARNING OBJECTIVES: After studying this article, the participant should: 1. Have a variety of options for thumb reconstruction. 2. Know the advantages and disadvantages of the nonmicrosurgical and microsurgical techniques for thumb reconstruction. 3. Understand the decision making from the variety of thumb reconstruction techniques based on patient needs. 4. Have a basic understanding of the various thumb reconstruction techniques discussed. The traumatic amputation of the thumb is an absolute indication for attempted replantation. The profound disability of the hand resulting from absence of the thumb, with loss of pinch and grasp, obliges the surgeon to make every attempt to replant the amputated thumb and preserve hand function. However, not all attempts at replantation result in survival of the amputated portion, and unreconstructable damage to or complete loss of the amputated part may preclude attempted replantation. In such situations, the surgeon must have alternative methods of dealing with the sequelae of thumb loss. This article will discuss nonmicrosurgical and microsurgical techniques for thumb reconstruction.  相似文献

Depression is a common mental disorder that co-occurs in other neurological and somatic diseases. Further, sex differences exist in the prevalence rates of many of these diseases, as well as within non-disease associated depression. In this review, the case is made for needing a better recognition of the source of the symptoms of depression with respect to the sex of the individual; in that, some disease states, which includes the neuroendocrine and immune reactions to the underlying pathophysiology of the disease, may initiate depressive symptoms more often in one sex over the other. The diseases specifically addressed to make this argument are: epilepsy, Alzheimer’s disease, cancer, and cardiovascular disease. For each of these conditions, a review of the following are presented: prevalence rates of the conditions within each sex, prevalence rates of depressive symptoms within the conditions, identified relationships to gonadal hormones, and possible interactions between gonadal hormones, adrenal hormones, and immune signaling. Conclusions are drawn suggesting that an evaluation of the root causes for depressive symptoms in patients with these conditions is necessary, as the underlying mechanisms for eliciting the depressive symptoms may be qualitatively different across the four diseases discussed. This review attempts to identify and understand the mechanisms of depression associated with these diseases, in the context of the known sex differences in the disease prevalence and its age of onset. Hence, more extensive, sex-specific model systems are warranted that utilize these disease states to elicit depressive symptoms in order to create more focused, efficient, and sex-specific treatments for patients suffering from these diseases and concurrent depressive symptoms.  相似文献

Microsurgical scalp reconstruction in the patient with cancer   总被引:2,自引:0,他引:2  
The literature regarding reconstruction of large scalp wounds with free tissue transfer consists mostly of case reports and small series, and none of the published reports focus on the particular problems of the oncology patient. Here the authors describe their experience with 37 flaps in 32 patients, all of whom required scalp reconstruction with free tissue transfer after tumor extirpation. Twenty-seven free flaps were performed at the time of the initial surgery and 10 were performed after a prior reconstruction failed. The authors describe the characteristics of the patients and procedures, including tumor type, wound size and complexity, flaps and recipient vessels used, preoperative and postoperative radiation therapy, and complications. Most (72 percent) of the tumors were recurrent or persistent. The free tissue transfer was successful in all patients. There was a 59 percent overall complication rate with 32 percent of patients requiring a secondary surgical procedure. Most of the complications were wound-healing complications. Although there were two cases of vein thrombosis, these were salvaged by revision, and no flaps were lost. Nine patients underwent postoperative radiation therapy that was well tolerated. Only four patients underwent cranioplasty at the time of the initial operation, and no secondary cranial reconstructions were performed. The authors conclude that preoperative and postoperative radiation therapies as well as the need for expedient tumor resection and immediate flap coverage are issues that make free tissue transfer attractive for the oncology patient who needs scalp reconstruction. Although the complication rate is relatively high and a significant percentage of patients require a secondary procedure, free flap coverage was efficacious for all patients in this group. Cranioplasty is not usually required but, if needed, alloplastic or autologous cranial reconstruction does not appreciably increase morbidity in the selected patient.  相似文献

Conventional antipsychotic drugs, although efficacious in the treatment of mania, have not demonstrated a significant usefulness in the maintenance treatment of bipolar disorder. This has primarily been due to a tendency to induce depressive symptoms and depressive recurrences in this group of patients in the course of long-term administration. However, the picture has changed following the introduction of second-generation antipsychotics. These drugs have pro-depressant properties (if any) that are much weaker than conventional antipsychotics. Furthermore, their tolerability, especially in long-term treatment, is more favorable compared to classical antipsychotics. Clinical observations of the action profile of second-generation antipsychotic drugs in the treatment of schizophrenia have pointed to a possibility of these agents possessing mood-stabilizing properties. The first such suggestion was made by Zarate (1995) in connection with clozapine. The prevention of manic and depressive recurrences in bipolar disorder is a hallmark of the definition of mood-stabilizers.  相似文献

Altered inflammatory cytokine profiles are often observed in individuals suffering from major depression. Recent clinical work reports on elevated IL-6 and decreased IL-10 in depression. Elevated IL-6 has served as a consistent biomarker of depression and IL-10 is proposed to influence depressive behavior through its ability to counterbalance pro-inflammatory cytokine expression. Clinical and animal studies suggest a role for IL-10 in modifying depressive behavior. Murine restraint stress (RST) is regularly employed in the study of behavioral and biological symptoms associated with depressive disorders. While responses to acute RST exposure have been widely characterized, few studies have examined the ongoing and longitudinal effects of extended RST and fewer still have examined the lasting impact during the post-stress period. Consistent with clinical data, we report that a protocol of prolonged murine RST produced altered cytokine profiles similar to those observed in major depressive disorder. Parallel to these changes in circulating cytokines, IL-10 mRNA expression was diminished in the cortex and hippocampus throughout the stress period and following cessation of RST. Moreover, chronic RST promoted depressive-like behavior throughout the 28-day stress period and these depressive-like complications were maintained weeks after cessation of RST. Because of the correlation between IL-10 suppression and depressive behavior and because many successful antidepressant therapies yield increases in IL-10, we examined the effects of IL-10 treatment on RST-induced behavioral changes. Behavioral deficits induced by RST were reversed by exogenous administration of recombinant IL-10. This work provides one of the first reports describing the biological and behavioral impact following prolonged RST and, taken together, this study provides details on the correlation between responses to chronic RST and those seen in depressive disorders.  相似文献

Background

Depression is a particularly common psychological disorder that affects cancer patients. Diagnosed with hematological malignancies constitute a serious unpredictable and uncontrollable medical stress situation and patients are susceptible to suffer from depressive symptoms. The aims of the study were to explore the correlation between perceived stress and depressive symptoms in patients with hematological malignancies, and assess the mediating role of mental adjustment between these variables.

Methods

A single center, cross-sectional study was performed by convenience sampling between July 2013 and April 2014 in a hospital of China. The Center for Epidemiologic Studies Depression Scale, Perceived Stress Scale, and Mini-Mental Adjustment Scale, as well as questions about demographic and clinical factors was distributed to 300 hematological cancer patients. Completed questionnaires were received from 227 inpatients.

Results

The results showed that perceived stress was positively correlated with depressive symptoms. The mental adjustment significantly mediated the relationship between perceived stress and depressive symptoms.

Conclusions

Among hematological cancer patients perceived stress may be a risk factor for depressive symptoms, whereas positive coping style might be protective against depressive symptoms. Results showed that medical managers could support the development of mental adjustment in the patients to alleviate psychological disorders.  相似文献

Background

The purpose of this study was to explore the potential risk factors associated with the failure of an upper extremity replantation with a focus on cigarette or tobacco use.

Patients and Methods

A cohort of 102 patients with 149 replants (6 extremities, 143 digits) and a mean age of 41 years (range 5 to 72 years) was enrolled in this study. The data collected included age, gender, tobacco/cigarettes use, trauma mechanism, underlying disease (e.g., hypertension (HTN), diabetes mellitus (DM), etc.), and vein graft use. An analysis with a multivariable regression was conducted to identify the risk factors of replant failure and their respective odds ratios (ORs).

Results

Multilevel generalized linear mixed models (GLMMs) with a binomial distribution and logit link showed that smoking did not increase the risk of replant failure (p = 0.234). In addition, the survival of replants was not affected by DM or HTN (p = 0.285 and 0.938, respectively). However, the replantation results were significantly affected by the age of the patients and the mechanism of injury. Patients older than 50 years and those with avulsion or crush injuries tended to have a higher risk of replant failure (OR = 2.29, 6.45, and 5.42, respectively; p = 0.047, 0.028, and 0.032, respectively).

Conclusions

This study showed that the use of cigarettes/tobacco did not affect the replantation outcome. The main risks for replant failure included being older than 50 years and the trauma mechanism (avulsion or crush injuries).  相似文献

We reviewed data from approximately 80 published and unpublished studies that examined the association of religious affiliation or involvement with depressive symptoms or depressive disorder. In these studies, religion was measured as religious affiliation; general religious involvement; organizational religious involvement; prayer or private religious involvement; religious salience and motivation; or religious beliefs. People from some religious affiliations appear to have an elevated risk for depressive symptoms and depressive disorder, and people with no religious affiliation are at an elevated risk in comparison with people who are religiously affiliated. People with high levels of general religious involvement, organizational religious involvement, religious salience, and intrinsic religious motivation are at reduced risk for depressive symptoms and depressive disorders. Private religious activity and particular religious beliefs appear to bear no reliable relationship with depression. People with high levels of extrinsic religious motivation are at increased risk for depressive symptoms. Although these associations tend to be consistent, they are modest and are substantially reduced in multivariate research. Longitudinal research is sparse, but suggests that some forms of religious involvement might exert a protective effect against the incidence and persistence of depressive symptoms or disorders. The existing research is sufficient to encourage further investigation of the associations of religion with depressive symptoms and disorder. Religion should be measured with higher methodological standards than those that have been accepted in survey research to date.  相似文献

The hypothesis that Thielaviopsis basicola might be the causal agent of the specific replant disorders of cherry and plum was tested in experiments with pot-grown trees and by observations on the distribution of the pathogen. The results obtained with certain strains of T. basicola simulated and were consistent with all features known to characterize the specific replant disorders, viz. inter- and intra-generic specificity of effect; host symptoms; establishment, immobility and persistence of the causal agent in soil; normal growth of affected trees after transfer to ‘non-replant’ soil; limited influence of soil type on the incidence of the disorder. T. basicola was therefore considered to be the probable causal agent of the specific replant diseases of certain Prunus species. The etiology of these diseases is discussed. T. basicola was neither pathogenic to apple nor associated with the growth of apple. The apparently closely similar specific replant disorder of Malus is therefore considered to be causally distinct from those of cherry and plum.  相似文献

Free-flap reconstruction of large defects of the scalp and calvarium   总被引:1,自引:0,他引:1  
Beyond a certain size, full-thickness defects of scalp are not amenable to local flap repair. Staged distant flaps have now been virtually eliminated by free-flap reconstruction. The authors present 12 patients in whom full-thickness scalp defects with an average area of 275 cm2 were reconstructed utilizing free flaps. Nine patients had corresponding large calvarial defects. Ten patients had reconstruction with free latissimus dorsi muscle flaps and overlying skin grafts, and one patient had reconstruction with a scapular free flap. Of the 12 patients, 8 had extirpative surgery for tumor with immediate reconstruction and the remaining 4 had reconstruction for chronic radionecrosis of the scalp, usually associated with infected osteoradionecrosis of the calvarium. Of this latter group, 2 patients underwent simultaneous acrylic cranioplasty. The technique and results are discussed.  相似文献

Trigeminal neuralgia is a disorder associated with severe episodes of lancinating pain in the distribution of the trigeminal nerve. Previous reports indicate that 80-90% of cases are related to compression of the trigeminal nerve by an adjacent vessel. The majority of patients with trigeminal neuralgia eventually require surgical management in order to achieve remission of symptoms. Surgical options for management include ablative procedures (e.g., radiosurgery, percutaneous radiofrequency lesioning, balloon compression, glycerol rhizolysis, etc.) and microvascular decompression. Ablative procedures fail to address the root cause of the disorder and are less effective at preventing recurrence of symptoms over the long term than microvascular decompression. However, microvascular decompression is inherently more invasive than ablative procedures and is associated with increased surgical risks. Previous studies have demonstrated a correlation between surgeon experience and patient outcome in microvascular decompression. In this series of 59 patients operated on by two neurosurgeons (JSN and PEK) since 2006, 93% of patients demonstrated substantial improvement in their trigeminal neuralgia following the procedure--with follow-up ranging from 6 weeks to 2 years. Moreover, 41 of 66 patients (approximately 64%) have been entirely pain-free following the operation. In this publication, video format is utilized to review the microsurgical pathology of this disorder. Steps of the operative procedure are reviewed and salient principles and technical nuances useful in minimizing complications and maximizing efficacy are discussed.  相似文献

Autism spectrum disorder often co-occurs with other psychiatric disorders. Although a high prevalence of autistic-like traits/symptoms has been identified in the pediatric psychiatric population of normal intelligence, there are no reports from adult psychiatric population. This study examined whether there is a greater prevalence of autistic-like traits/symptoms in patients with adult-onset psychiatric disorders such as major depressive disorder (MDD), bipolar disorder, or schizophrenia, and whether such an association is independent of symptom severity. The subjects were 290 adults of normal intelligence between 25 and 59 years of age (MDD, n=125; bipolar disorder, n=56; schizophrenia, n=44; healthy controls, n=65). Autistic-like traits/symptoms were measured using the Social Responsiveness Scale for Adults. Symptom severity was measured using the Positive and Negative Symptoms Scale, the Hamilton Depression Rating Scale, and/or the Young Mania Rating Scale. Almost half of the clinical subjects, except those with remitted MDD, exhibited autistic-like traits/symptoms at levels typical for sub-threshold or threshold autism spectrum disorder. Furthermore, the proportion of psychiatric patients that demonstrated high autistic-like traits/symptoms was significantly greater than that of healthy controls, and not different between that of remitted or unremitted subjects with bipolar disorder or schizophrenia. On the other hand, remitted subjects with MDD did not differ from healthy controls with regard to the prevalence or degree of high autistic-like traits/symptoms. A substantial proportion of adults with bipolar disorder and schizophrenia showed high autistic-like traits/symptoms independent of symptom severity, suggesting a shared pathophysiology among autism spectrum disorder and these psychiatric disorders. Conversely, autistic-like traits among subjects with MDD were associated with the depressive symptom severity. These findings suggest the importance of evaluating autistic-like traits/symptoms underlying adult-onset psychiatric disorders for the best-suited treatment. Further studies with a prospective design and larger samples are needed.  相似文献

BORDERLINE PERSONALITY DISORDER is a chronic psychiatric disorder characterized by marked impulsivity, instability of mood and interpersonal relationships, and suicidal behaviour that can complicate medical care. Identifying this diagnosis is important for treatment planning. Although the cause of borderline personality disorder is uncertain, most patients improve with time. There is an evidence base for treatment using both psychotherapy and psychopharmacology. The clinical challenge centres on managing chronic suicidality.CaseColleen, a 22-year old student, is seen for a psychiatric assessment after presenting to the emergency department because of taking an overdose of acetaminophen pills. Although the immediate precipitant to her suicide attempt was a break-up with her boyfriend, she has a history of multiple suicide attempts since the age of 14. Colleen reports that she has daily mood swings, from depression to intense anger, and that she often cuts herself on the wrists and arms to relieve dysphoria. When stressed, she experiences feelings of unreality, sometimes hearing a voice telling her to kill herself. Colleen has had highly problematic relationships with men, falling quickly in and out of love and feeling that her life depends on them, even when they have behaved abusively toward her. What is the appropriate diagnosis and management of this patient?Personality disorders constitute a major group in the classification of mental disorders. According to the Diagnostic and Statistical Manual of Mental Disorders, fourth edition, text revision (DSM-IV-TR),1 these conditions are defined by maladaptive personality characteristics beginning early in life that have consistent and serious effects on functioning. Borderline personality disorder (BPD) is frequently seen in clinical practice.2 Characterized by emotional turmoil and chronic suicidality (suicide ideation and attempts), this type of personality disorder presents some of the most difficult and troubling problems in all of psychiatry.  相似文献

Stuttering is a speech disorder with disruption of verbal fluency which is occasionally present in patients with Parkinson's disease (PD). Long-term medical management of PD is frequently complicated by fluctuating motor functions and dyskinesias. High-frequency deep brain stimulation (DBS) of the subthalamic nucleus (STN) is an effective treatment of motor fluctuations and is the most common surgical procedure in PD. Here we report the re-occurrence and aggravation of stuttering following STN-DBS in two male patients treated for advanced PD. In both patients the speech fluency improved considerably when the neurostimulator was turned off, indicating that stuttering aggravation was related to neurostimulation of the STN itself, its afferent or efferent projections and/or to structures localized in the immediate proximity. This report supports previous studies demonstrating that lesions of the basal ganglia-thalamocortical motor circuit, including the STN, is involved in the development of stuttering. In advanced PD STN-DBS is generally an effective and safe treatment. However, patients with PD and stuttering should be informed about the risk of aggravated symptoms following surgical therapy.  相似文献

Activities of caspases involved in cell death have been investigated in lymphocytes of patients with borderline personality disorders (BPD). In the group of patients with organic mental disorders (OMD) caspase activity decreased in a depressive disorder and increased in an anxiety disorder, thus suggesting activation of apoptosis in lymphocytes of patients with the anxiety disorder. Caspase activities differed in lymphocytes of OMD patients with the depressive disorder and a recurrent depressive disorder. In BPD patients with OMD lymphocyte caspase activity was higher thus indicating activation of apoptosis in these cells. Results can be used for specification of mechanisms of pathogenesis of mental disorders and search for new markers of these diseases.  相似文献

Background

Some patients report a preoccupation with a specific aversive human sound that triggers impulsive aggression. This condition is relatively unknown and has hitherto never been described, although the phenomenon has anecdotally been named misophonia.

Methodology and Principal Findings

42 patients who reported misophonia were recruited by our hospital website. All patients were interviewed by an experienced psychiatrist and were screened with an adapted version of the Y-BOCS, HAM-D, HAM-A, SCL-90 and SCID II. The misophonia patients shared a similar pattern of symptoms in which an auditory or visual stimulus provoked an immediate aversive physical reaction with anger, disgust and impulsive aggression. The intensity of these emotions caused subsequent obsessions with the cue, avoidance and social dysfunctioning with intense suffering. The symptoms cannot be classified in the current nosological DSM-IV TR or ICD-10 systems.

Conclusions

We suggest that misophonia should be classified as a discrete psychiatric disorder. Diagnostic criteria could help to officially recognize the patients and the disorder, improve its identification by professional health carers, and encourage scientific research.  相似文献

Because life-threatening sternal wound complications can occur following sternotomy, the optimal management of sternal wound infections remains an important topic. To decrease morbidity following operative treatment of these patients, the authors made a number of refinements in their treatment protocol over the past several years, particularly with regard to the extent of débridement, method of flap apposition, and management of drains. The purpose of this study was to obtain specific outcomes data by reviewing a large series of patients treated by a single surgeon. In this series of 114 consecutive sternal wounds treated by the senior author (Ascherman), patients were managed almost exclusively with débridement and immediate closure with bilateral pectoralis major myocutaneous advancement flaps. There were no intraoperative deaths. The 30-day perioperative mortality rate was 7.9 percent, with only one death directly related to sternal infection. Nineteen patients (16.7 percent) experienced postoperative morbidity, including partial wound dehiscences (5 percent), skin edge necrosis (5 percent), and seromas (3.5 percent). The authors advocate single-stage management of complicated sternal wounds with immediate débridement and bilateral pectoralis major myocutaneous advancement flaps. The procedure is rapid and effective. Refinements in technique have significantly lowered morbidity.  相似文献

A significant portion of patients with 22q11 deletion syndrome (22q11DS) develop psychiatric disorders, including schizophrenia and other psychotic and affective symptoms, and the responsible gene/s are assumed to also play a significant role in the etiology of nonsyndromic psychiatric disease. The most common psychiatric diagnosis among patients with 22q11DS is schizophrenia, thought to result from neurotransmitter imbalances and also from disturbed brain development. Several genes in the 22q11 region with known or suspected roles in neurotransmitter metabolism have been analyzed in patients with isolated schizophrenia; however, their contribution to the disease remains controversial. Haploinsufficiency of the TBX1 gene has been shown to be sufficient to cause the core physical malformations associated with 22q11DS in mice and humans and via abnormal brain development could contribute to 22q11DS-related and isolated psychiatric disease. 22q11DS populations also have increased rates of psychiatric conditions other than schizophrenia, including mood disorders. We therefore analyzed variations at the TBX1 locus in a cohort of 446 white patients with psychiatric disorders relevant to 22q11DS and 436 ethnically matched controls. The main diagnoses included schizophrenia (n = 226), schizoaffective disorder (n = 67), bipolar disorder (n = 82), and major depressive disorder (n = 29). We genotyped nine tag SNPs in this sample but did not observe significant differences in allele or haplotype frequencies in any of the analyzed groups (all affected, schizophrenia and schizoaffective disorder, schizophrenia alone, and bipolar disorder and major depressive disorder) compared with the control group. Based on these results we conclude that TBX1 variation does not make a strong contribution to the genetic etiology of nonsyndromic forms of psychiatric disorders commonly seen in patients with 22q11DS.  相似文献

Suicide is the ninth major cause of death in the nation. California, according to the latest comprehensive figures (1949), ranks about 50 per cent above the national average. Yet the importance of suicide as a cause of death is gravely underestimated. At hospitals and other agencies only emergency treatment is given before discharge of persons who attempt suicide, although it is known that many will repeat the attempt. Rarely is psychiatric evaluation carried out or definitive treatment prescribed. Suicidal symptoms are often ignored in other cases. Physicians have a responsibility, as in any disorder, to recognize signs and symptoms of impending suicide and to use all means of prevention. Prevention could be forwarded by the education of physicians and laymen in detecting early signs of depression, in recognizing accident proneness, and in insisting upon legal control of use of barbiturates, a common means of suicide. Lay associations should encourage individuals with suicidal impulses to go to psychiatric clinics for help. Police should learn how to deal with suicidal attempts, and hospitals should include psychiatric examination and advice as to treatment of all such persons. Suicidal attempts should be registered and reported to public health officers in the same way as are other dangerous diseases. More research should be done on case records of these patients, in order to better understand motivations and means of prevention.  相似文献

Cognitive theories of depression posit that perception is negatively biased in depressive disorder. Previous studies have provided empirical evidence for this notion, but left open the question whether the negative perceptual bias reflects a stable trait or the current depressive state. Here we investigated the stability of negatively biased perception over time. Emotion perception was examined in patients with major depressive disorder (MDD) and healthy control participants in two experiments. In the first experiment subjective biases in the recognition of facial emotional expressions were assessed. Participants were presented with faces that were morphed between sad and neutral and happy expressions and had to decide whether the face was sad or happy. The second experiment assessed automatic emotion processing by measuring the potency of emotional faces to gain access to awareness using interocular suppression. A follow-up investigation using the same tests was performed three months later. In the emotion recognition task, patients with major depression showed a shift in the criterion for the differentiation between sad and happy faces: In comparison to healthy controls, patients with MDD required a greater intensity of the happy expression to recognize a face as happy. After three months, this negative perceptual bias was reduced in comparison to the control group. The reduction in negative perceptual bias correlated with the reduction of depressive symptoms. In contrast to previous work, we found no evidence for preferential access to awareness of sad vs. happy faces. Taken together, our results indicate that MDD-related perceptual biases in emotion recognition reflect the current clinical state rather than a stable depressive trait.  相似文献
