The physician can be further reassured that in follow-up studies of patients with so-called conversion disorder (exclusive of pseudoseizures), virtually none develop a neurologic lesion that in retrospect was related to the initial episode as for example in the study by Stone and colleagues. It is of interest that in the series cited, most patients had persistent functional disability from their conversion symptoms, even a decade later. So-called projective tests (the Rorschach and Thematic Apperception Tests), which for a time were popular with dynamic psychiatrists, are not helpful in diagnosis and are now used very little. The presence of extreme suggestibility and the tendency to dramatize symptoms as measured by one part of the Minnesota Multiphasic Personality Inventory and other psychometric tests is helpful in diagnosis but not pathognomonic of the disease; these traits appear under certain conditions in individuals who never develop hysteria. Finally it should be reemphasized that single bouts of isolated hysterical paresis, blindness, and anesthesia are quite common in neurologic practice and do not presage a chronic hysterical illness. The same is true for transient neurologic signs exhibited during the course of the examination, mainly pertaining to unusual or drifting sensory loss or asthenic weakness of a limb. Treatment of Hysteria this may be considered from two aspects: the correction of the long-standing basic personality defect and relieving the recently acquired physical symptoms. Psychoanalysts have attempted to modify it by longterm reeducation, but their results are uninterpretable, and there are no control studies for the few reports of therapeutic success. Many psychiatrists are inclined to regard the female with hysteria who has a lifelong history of ill health as having a severe personality disorder- i. In other, less severe cases and especially in those in whom hysterical symptoms have appeared under the pressure of a major crisis, explanatory and supportive psychotherapy appears to be helpful, and the patients have been able thereafter to resume their places in society. One tactic is to treat the patient as though she has had an illness and is now in the process of recovering. The earlier this is done after the development of symptoms, the more likely they are to be relieved. Sometimes a single symptom such as hemiparesis or tremor can be halted by a particular maneuver and this demonstration suffices to begin recovery. In chronically bedridden patients, strong pressure to get out of bed and resume function must be applied. Several approaches to discussing the symptomatology with the patient have been suggested. At one extreme is a confrontative approach in which the patient is told the symptoms are psychologic, or "in your head. On the other extreme is complete avoidance on the part of the physician, an approach that is almost as unproductive. We prefer to ask the patient if the symptoms can in some way be the result of "stress" or an upsetting recent experience. On occasion, in private we will inquire about childhood sexual abuse and often get an affirmative response from the patient, with later confirmation by a spouse or sibling. We have found it very useful to list the diseases that have been excluded by examination and testing: brain tumor, stroke, amyotrophic lateral sclerosis, multiple sclerosis, etc. This often evokes an acknowledgment by the patient that one of the diseases had been a preoccupying concern. We then indicate, without using psychologic terms, that the brain may at times adopt certain patterns of behavior that do not reflect structural damage, and furthermore, these patterns can be unlearned with physical therapy and time as described below. One group seems not to mind and to be relieved by the expression of concern and reassurance that there is no dangerous disease at the root of the problem. Some have objected to the explanation based on their own view, often derived from research on the internet and with similarly afflicted persons, that Lyme disease, chronic viral infection, environmental toxins, allergies, etc. All that the physician can offer here is an openness to see and reexamine the patient in several months; "cure" has no meaning in these instances and there is a great likelihood that such individuals will see a long line of doctors. Persuasion and suggestion, both direct and indirect, should be employed as already noted. Illustratively, the patient should be repeatedly encouraged, told that she is improving, urged to resume work or other duties, and continue participation in routine activities. Some of our best results have been obtained by indicating that the neurologic symptoms are a "constitutional" weakness that can be overcome by physical and other therapies.

There are, of course, a great number of established therapies which combine cognitive and behavioural approaches to 10 Treating early stuttering 215 the treatment of early stuttering which we have not mentioned here. Key points · · · · · Factors such as familial history of stuttering, poor language, phonological or motor speech skills, high parental expectation, extra demands placed on language processing, all increase the likelihood of eventual stuttering. The Demands and Capacities model provides a useful framework with which to explain why a child may be at risk of stuttering, or actually is stuttering, and also how therapy intends to deal with the issues. In the case of interaction therapy, this will be done by reducing the demands placed on the child, whose capacity for Я uent speech and language has (for a number of potential reasons) been reduced. Whether the Lidcombe Program increases capacity or reduces demand awaits the outcome of studies currently underway to determine the exact underlying nature of the operant that the child responds to . Families of preschool children who are not stuttering but are at increased risk of doing so may beneЮ t from a counselling approach to minimize realization of the increased risk. Therapy may take the form of indirect (environment modiЮ cation) or direct (stuttering modiЮ cation) approaches. The direct approaches include strongly operant regimes (for example, Lidcombe Program) and less rigorously enforced speech modiЮ cation approaches (Van Riper, 1973; and see further reading). Here Conture describes his stuttering modification approach to early onset stuttering in which he emphasizes the differences between causal and precipitating factors. Desensitization procedures are also applied, as is a parent counselling program which aims to help the parent identify the situations that result in increased stuttering. A direct treatment approach that primarily relies on fluency shaping strategies, but also combines some Van Riperian stuttering modification strategies and interactional components. A thorough guide to the use of interaction therapy, as practised at the Michael Palin Centre for stammering children. The text is punctuated throughout with helpful case examples to illustrate assessment and therapeutic procedures. This recent edited publication covers all aspects of the Lidcombe Program, both theoretical and practical, in great detail. This is the most comprehensive single source for information on this approach currently available. In addition to chapters by the editors on the development and procedures involved in the running of the Lidcombe Program, there are further chapters containing descriptions as to how the program is being developed worldwide. Some consider this book better than the second edition (Ryan, 2001), which is recommended reading in the following chapter. Some children may have already attended preschool nursery groups, but the atmosphere here is informal, and for many children primary school is the first time that they are aware of a need to be accepted by their peers. Even at this early age, children who are either rather tall, or rather short, have red hair, ears which stick out a little, wear glasses, or have any other feature that might be seen as distinguishing are very likely to have these aspects pointed out to them by their classmates. These observations may for the most part be good natured, but even well-intentioned comments can be upsetting, and barbed comments can positively hurt. Relatedly, the onset of school can also very quickly bring into sharp focus any difficulty that a child may have that may set him aside as being different in any way from the norm. Those with any form of obvious physical handicap are at risk, and children with stutters who experience physical difficulty in saying words may be particularly vulnerable. Now the child has to deal not only with a stutter, but the reactions of his peers and his teachers. At a period where it is likely the child is becoming more aware of his difficulty in speech, he now has to deal with negative reactions from his classmates (Franck, Jackson, Pimentel, & Greenwood, 2003), and social rejection and bullying can be a particular problem for many children who stutter (Davis, Howell, & Cook, 2002; Hugh-Jones & Smith, 1999; Langevin, Bortnick, Hammer, & Weibe, 1998). Unlike many with physical disabilities, the child with a stutter may to a greater or lesser extent be able to hide this problem. This in turn may lead to increased struggle, tension and escape behaviour, which may result in more stuttering and more unwanted attention focused on the lack of verbal acuity. Some teachers, who are unsure as how best to help may unknowingly contribute to the problem by insisting he directly answers questions in front of the class. We have seen a great many children, even at primary school level, who would prefer to be thought of as unintelligent, and uninterested, and will either avoid answering questions or answer with a shrug of the shoulders or give a deliberately incorrect answer to a question they knew the answer to , rather than be seen to stutter.

Incipient respiratory failure is usually marked by a reduction of vital capacity, often accompanied by restlessness, anxiety, diaphoresis, or tremor. Once the diaphragm fails, movements of the chest wall and abdomen become paradoxical (the abdomen moves inward during inspiration) or there may be shallow excursions of the chest, alternating with paradoxical movements. In an emergency, after clearing of the airway, such a patient can be supported briefly by a tight-fitting face mask and manual bag (Ambu) breathing. The chest wall will be found to be very compliant as a result of muscular weakness. Treatment of Myasthenic Crisis Management of the crisis entails timely and careful intubation followed by mechanical ventilation in a critical care unit that is equipped to attend to the medical and neurologic needs of such patients. One must cope with both the oropharyngeal weakness that endangers the airway and the diaphragmatic weakness. Anticholinergic drugs, which exaggerate secretions, are best withdrawn at the time of intubation. The use of plasma exchange as described earlier appears to hasten improvement and weaning from the ventilator. Intravenous gamma globulin may be a useful alternative but has not been studied extensively. Some of our colleagues have used high-dose corticosteroid infusions, but this measure has not been particularly successful in our unit and, in the short run, carries the risk of inducing worsening of the weakness (Panegyres et al). Patients may respond to plasma exchange or immunoglobulin infusions in 1 or 2 days, but more often a week or more is required for recovery. It is generally best to wait 2 or 3 weeks before committing a patient to tracheostomy. Oral doses of 60 mg pyridostigmine or 15 mg neostigmine are roughly equivalent to 0. The management of the critically ill patient with myasthenia has been reviewed in the monograph by Ropper and colleagues. Most patients with myasthenic crisis will take several weeks to recover, and a few of our patients have remained ventilatordependent for months. In the extensive experience from ColumbiaPresbyterian, half of patients could be safely extubated within 2 weeks and three-quarters by a month (Thomas et al). There were 7 deaths among 53 patients, reflecting the gravity of this syndrome even in the modern era of intensive care. Atelectasis, severe anemia, congestive heart failure, and clostridial diarrhea (associated with antibiotic use) portend a prolonged period of generalized weakness and intubation. From time to time one encounters a patient in whom respiration and ambulation do not improve for many months after a myasthenic crisis. In our experience, these have been middle-aged or older patients, usually women, in whom an element of hyperthyroidism or hypothyroidism may have been operative. They become wasted as the proximal limb and axial muscles, including the diaphragm, fail to recover their power, even though the ocular and oropharyngeal muscles improve. The only recourse in cases of long-standing and severe myasthenia is to continue an average dose of corticosteroids and anticholinesterase medications with intermittent trials of immune globulin or plasma exchanges. This is also a situation in which high-dose cyclophosphamide followed by granulocyte-stimulating factor as mentioned earlier may result in slow improvement. The issues of neonatal myasthenia and of reduced intrauterine movements are considered later. The Lambert-Eaton myasthenic syndrome, neonatal myasthenia, the congenital myasthenic syndromes, and the myasthenic syndromes induced by drugs and toxins are the main disorders in this group. Two additional important members- botulism and organophosphate poisoning- are described elsewhere in the book (pages 1032 and 1037, respectively). Unlike classic myasthenia gravis, the muscles of the trunk, shoulder girdle, pelvic girdle, and lower extremities are the ones that become weak and fatigable. Often the first symptoms are difficulty in arising from a chair, climbing stairs, and walking; the shoulder muscles are affected later.

Capillary refill and pulse oximetry waveforms can give some indication of blood flow to injured digits. Median nerve: Between the flexor carpi radialis and palmaris longus tendons at wrist crease. Metacarpal block: Between the metacarpal heads all the way to the palmar aspect of the hand. An allergy to a local anesthetic is rare and in most cases is due to preservatives (methylparaben) within the anesthetic. All wrist and hand movements depend on the proper alignment and orientation of the eight carpal bones and their articulations with the distal forearm and proximal metacarpals. Also called the carpal navicular, this is the most commonly fractured bone of the wrist (60-80%). Proximal fractures have greater incidence of non-union with subsequent avascular necrosis. X-ray: Usually seen as fracture of the hook of the hamate, on the volar edge of the bone. Goal of closed reduction includes regaining normal anatomic alignment-volar Hand and Wrist Injuries Page 371 tilt (11 degrees), radial tilts (22 degrees), and radial height (11 mm). Barton fracture: Dorsal or volar rim fracture of the radius with subluxation or dislocation of the carpal bones. Perilunate dislocation: Dislocation of the joint between the lunate and the capitate. On the lateral view, the lunate remains articulated with the distal radius, but the capitate is dislocated Hand and Wrist Injuries Page 372 dorsally. This dislocation is often seen with associated fractures, and thus can be missed if not sought carefully. Lunate dislocation: this dislocation is similar in presentation to the perilunate. On the lateral view, the lunate is "spilled" from the cup of the distal radius ("spilled tea-cup" sign). Rotational deformities: It is important to detect and correct any rotational deformities before healing occurs, as later repair is difficult. These are often comminuted and dislocated, as the abductor pollicis longus tendon pulls the fragments. Initial reduction will often not be maintained, Hand and Wrist Injuries Page 374 even with splints or buddy taping. Intra-articular fracture: these may need reduction if significant portions of the joint are involved. The force causes an avulsion of the extensor tendon at the dorsal base of the distal phalanx. If greater than 25% of the joint space is involved, surgical repair may be indicated. These structures provide resistance to injury, but can be subject to large forces when the digit is twisted or forcibly extended. There are also collateral ligaments, which are supported by the lumbrical muscles. The arrangement provides the ability to abduct when extended, but not when flexed. These injuries need to be X-rayed, as tiny fragments of avulsed bone at the joint signify ligament avulsion. Open injuries need orthopedic consultation for debridement, irrigation, antibiotics, and close follow-up. The complex anatomy protects against dislocation, but also leads to a higher incidence of irreducible dislocations. These are termed simple because they are usually easily reduced with closed techniques. This is due to the interposition of torn ligaments and the arrangement of ligaments and lumbrical muscles that actually tighten around the head of the metacarpal as traction is applied, which prevents reduction. The zones of extensor tendon injury can be more easily remembered by noting that oddnumbered zones are over joints, while even-numbered zones are over bones.
