Gaze-evoked amaurosis has been associated with a variety of mass lesions and is thought to result from decreased blood flow to the retina from compression of the central retinal artery with eye movement. Amblyopia Amblyopia refers to poor visual acuity, most usually in the context of a “lazy eye,” in which the poor acuity results from the failure of the eye to establish normal cortical representation of visual input during the critical period of visual maturation (between the ages of six months and three years). This may result from: Strabismus Uncorrected refractive error Stimulus deprivation. Amblyopic eyes may demonstrate a relative afferent pupillary defect, and sometimes latent nystagmus. Amblyopia may not become apparent until adulthood when the patient suddenly becomes aware of unilateral poor vision. The finding of a latent strabismus (heterophoria) may be a clue to the fact that such visual loss is long-standing. The word amblyopia has also been used in other contexts: bilateral simultaneous development of central or centrocecal scotomas in chronic alcoholics has often been referred to as tobacco-alcohol ambly- opia, although nutritional optic neuropathy is perhaps a better term. Cross References Esotropia; Heterophoria; Nystagmus; Relative afferent pupillary defect (RAPD); Scotoma Amimia - see HYPOMIMIA Amnesia Amnesia is an impairment of episodic memory, or memory for per- sonally experienced events (autobiographical memory). This is a com- ponent of long-term (as opposed to working) memory, which is distinct from memory for facts (semantic memory), in that episodic memory is unique to the individual whereas semantic memory encom- passes knowledge held in common by members of a cultural or lin- guistic group. Episodic memory generally accords with the lay perception of memory, although many complaints of “poor memory” represent faulty attentional mechanisms rather than true amnesia. A precise clinical definition for amnesia has not been demarcated, per- haps reflecting the heterogeneity of the syndrome. Amnesia may be retrograde (for events already experienced) or anterograde (for newly experienced events). Retrograde amnesia may - 21 - A Amnesia show a temporal gradient, with distant events being better recalled than more recent ones, relating to the duration of anterograde amnesia. In a pure amnesic syndrome, intelligence and attention are normal and skill acquisition (procedural memory) is preserved. Amnesia may occur as one feature of more widespread cognitive impairments (e. These include the Wechsler Memory Score (WMS-R), the Recognition Memory Test which has both verbal (words) and visual (faces) subdiv- isions, the Rey Auditory Verbal Learning Test (immediate and delayed free recall of a random word list), and the Rey-Osterreith Complex Figure (nonverbal memory). Retrograde memory may be assessed with a structured Autobiographical Memory Interview and with the Famous Faces Test. Poor spontaneous recall, for example of a word list, despite an adequate learning curve, may be due to a defect in either storage or retrieval. This may be further probed with cues: if this improves recall, then a disorder of retrieval is responsible; if cueing leads to no improve- ment, or false-positive responses are equal or greater than true posi- tives, then a learning defect (true amnesia) is the cause. The neuroanatomical substrate of episodic memory is a distrib- uted system in the medial temporal lobe and diencephalon sur- rounding the third ventricle (the circuit of Papez) comprising the entorhinal area of the parahippocampal gyrus, perforant and alvear pathways, hippocampus, fimbria and fornix, mammillary bodies, mammillothalamic tract, anterior thalamic nuclei, internal capsule, cingulate gyrus, and cingulum. Basal forebrain structures (septal nucleus, diagonal band nucleus of Broca, nucleus basalis of Meynert) are also involved. Classification of amnesic syndromes into subtypes has been pro- posed, since lesions in different areas produce different deficits reflect- ing functional subdivision within the system; thus left temporal lesions produce problems in the verbal domain, right sided lesions affect non- verbal/visual memory. A frontal amnesia has also been suggested, although impaired attentional mechanisms may con- tribute. Functional imaging studies suggest medial temporal lobe acti- vation is required for encoding with additional prefrontal activation with “deep” processing; medial temporal and prefrontal activation are also seen with retrieval. Many causes of amnesia are recognized, including: ● Acute/transient: Closed head injury Drugs - 22 - Amusia A Transient global amnesia Transient epileptic amnesia Transient semantic amnesia (very rare) ● Chronic/persistent: Alzheimer’s disease (may show isolated amnesia in early disease) Sequela of herpes simplex encephalitis Limbic encephalitis (paraneoplastic or nonparaneoplastic) Hypoxic brain injury Temporal lobectomy (bilateral; or unilateral with previous contralateral injury, usually birth asphyxia) Bilateral posterior cerebral artery occlusion Korsakoff’s syndrome Bilateral thalamic infarction Third ventricle tumor, cyst Focal retrograde amnesia (rare) Few of the chronic persistent causes of amnesia are amenable to specific treatment. Plasma exchange or intravenous immunoglobulin therapy may be helpful in nonparaneoplastic limbic encephalitis associated with autoantibodies directed against voltage-gated potassium channels. Functional or psychogenic amnesia may involve failure to recall basic autobiographical details, such as name and address. Reversal of the usual temporal gradient of memory loss may be observed (but this may also be the case in the syndrome of focal retrograde amnesia).
In the case of advanced- and terminal-stage OA levitra 20 mg without a prescription erectile dysfunction latest medicine, when there is no longer cartilage in the weight-bearing surface buy levitra 20mg lowest price impotence ring, then the congru- ency should be destroyed ﬁrst to improve the mechanical condition and to assist the formation of repair tissue and promote the repair of the articular surface. The question is whether the cartilage would simply disappear, or whether chondroid plug-producing bone marrow would appear in the articular surface. If we wanted to treat all cases the same way, with enlarged weight-bearing area and improved congruency, as was the case in pre- and initial-stage OA, there is a limit to what we could accomplish. OA Joint Reconstruction Without Replacement Surgery 177 Significance of VFO for Advanced- and Terminal-Stage OA in Middle-Aged Patients Dr. Takatori presented the effectiveness of rotational acetabular osteotomy (RAO). For example, what happens if RAO is performed at the age of 35, as opposed to doing nothing at that age and THR at the age of 45? If a patient did nothing until 45, she would have progression of OA and require THR at 45. Assuming that she enjoys an average life span, she would require a second revision. However, if the patient had an RAO at the age of 35, her ﬁrst THR would be around the age of 60, and the second THR around 75, and she would only require a single revision surgery in her lifetime. Now the next question is what happens if the patient was not treated by RAO and had VFO at the age of 45, instead of THR. The average course of VFO shows that the patient would require her ﬁrst THR around the age of 60, and her second THR, or revision, at the age of around 75. Even if the patient is not indicated for RAO because of the advanced or terminal stage of OA, it is questionable whether she should have THR for her ﬁrst surgery. The question here, however, is the difference of the clinical result that can be expected from THR versus VFO at the age of 45. Thus, it is all up to the surgeon to decide whether one would be willing to accept this, or whether one would prefer multiple revisions. While plans were being made, an nonsteroidal antiinﬂammatory drug (NSAID) was given on a pro re nata (PRN) basis, and I instructed her to start using crutches. Five years later, almost all orthopedic surgeons must think that THR was deﬁnitely necessary with this condition (Fig. However, this was only a radiologic ﬁnding, and she was no longer complaining of much pain.

On the other hand, marked development of roof and ﬂoor osteophytes can be seen. The formation of a ﬁne set of roof osteophyte and ﬂoor osteophyte can be seen on the radiogram. Joint space is very wide, the roof osteophyte has matured, and the joint was reconstructed and regenerated into a nice spherical joint. Osteoarthritis is characterized by the coexistence of wear and a destructive phase and the proliferative, reparative, and regenerative phase. It seems, at the present time, that not only the patients but we, the orthopedic surgeons, hurry too much. It may be that we are nipping the natural reparative capacity in the bud by rushing too much. So, we do not actively recommend an operation on our part until the patient asks for surgery. Only when the patient asks for surgery do we then would provide information about the type of operation that can be offered. Sugioka said in his lecture, hospital administrators need to improve ﬁnancial status by ensuring a shorter length of stay. On other hand, however, in my day-to-day practice, I strongly feel that osteoarthritis cases should not be dealt with in the same manner as rheumatoid arthritis and other destructive joint diseases. Conclusion I have tried to describe the principles of treatment of OA of younger patients and to share our results and experience with joint preservation surgery in advanced and terminal cases, emphasizing the signiﬁcance of osteotomy. Osteophytes are formed on the acetabular edge and margin of the femoral head as a result of biological response to the biomechanical environment of the joint, reﬂect- ing the natural biological regenerative capacity to heal. We need to try to more effec- OA Joint Reconstruction Without Replacement Surgery 179 tively use these osteophytes.
J Bone Joint Surg 78B:745–750 Retrospective Evaluation of Slipped Capital Femoral Epiphysis 1 1 1 1 Meishuu Ko generic levitra 10mg free shipping erectile dysfunction doctor singapore, Kouji Ito safe 20 mg levitra new erectile dysfunction drugs 2014, Keiji Sano , Naoki Miyagawa , 2 2 Kengo Yamamoto , and Youichi Katori Summary. We treated 16 patients (16 hips) with slipped capital femoral epiphysis (12 boys and 4 girls) encountered during the previous 16-year period. The evaluation items were chief complaint, mecha- nism of injury, initial diagnosis, disease type, radiographic ﬁndings, physique and endocrinological abnormalities, treatment methods, and complications. The disease type was acute slip in 2 patients, chronic slip in 8, and acute on chronic slip in 6. Mild slip was observed in 10 patients, moderate slip in 5, and severe slip in 1. Surgery was performed in all patients; Southwick intertrochanteric osteotomy was performed in 5 patients and in situ pinning in 11. Concerning surgical complications, methicillin-resistant Staphy- lococcus aureus infection developed in 1 patient and k-wire breakage in 1. Limitation of motion remained in 6 hips, but no hip pain, and normal gait was attained. Slipped capital femoral epiphysis, Retrospective evaluation, Osteotomy, In situ pinning, Early diagnosis Introduction The report in 2004 by the Multicenter Study Committee of the Japanese Pediatric Orthopaedic Association showed a deﬁnite increase in patients with slipped capital femoral epiphysis during the previous 25-year period in Japan. However, physi- cians other than pediatric surgeons are infrequently aware of slipped capital femoral epiphysis and do not include this entity in diseases for differential diagnosis; there- fore, its diagnosis rate is low. In addition, there are no treatment methods with established evidence at present. We encountered 16 patients with slipped capital 1Department of Orthopedic Surgery, Tokyo Medical University Hachioji Medical Center, 1163 Tatemachi, Hachioji, Tokyo 193-0944, Japan 2Department of Orthopedic Surgery, Tokyo Medical University, Tokyo, Japan 69 70 M. Subjects and Methods The subjects were 16 patients (12 boys and 4 girls) encountered during the previous 16-year period. The evaluation items were chief complaint, mechanism of injury, initial diagnosis, disease type, radio- graphic ﬁndings such as the slipping angle, physique and endocrinological abnor- malities, treatment methods, and complications. For radiographic evaluation, the head–shaft angle on frontal images and the pos- terior tilting angle in the frog-leg position were measured, and the right–left differ- ence was regarded as the slipping angle. The severity of the disease was evaluated mainly based on the posterior tilting angle. Results The chief complaint was hip joint pain in 11 patients, pain from the hip joint to the knee in 3, pain from the hip joint to the thigh in 1, femoral pain in 1, and lower limb pain in 1. The mechanism of injury was sports in 8 patients, falling during running in 1, falling on the stairs in 1, long-distance walking in 1, and unknown in 3: most patients had relatively mild injuries. The mean interval between the onset of symp- toms to the initial visit to the hospital was 69 days and that from the initial visit to diagnosis was 30 days. The duration until diagnosis was relatively short in patients with acute slip but considerably longer in some patients with chronic or acute on chronic slip. The coefﬁcient of the correlation between the onset of symptoms and diagnosis was 0. The initial treatment was performed by an orthopedic surgeon in 11 patients, a surgeon in 3, a pediatrician in 2, and a bonesetter in 1. The initial diagnosis was slipped capital femoral epiphysis in 5 patients, absence of abnormalities in 3, Perthes disease in 2, unknown in 2, and growing pain, transient synovitis of the hip, and femoral neck fracture in 1 each. At the time of the visit to our hospital, a correct diagnosis was soon made in all patients. The disease type was acute slip in 2 patients, chronic slip in 8, and acute on chronic slip in 6. Mild slip (between 0° and 30°) was observed in 10 patients, moderate slip (between 30° and 60°) in 5, and severe slip (>60°) in 1 (Fig. The mean interval between the onset of symptoms and the initial visit to the hos- pital was 69 days and that from the ﬁrst visit to diagnosis was 30 days. The physique (height, weight) of the patients was compared with its distribution according to age reported by the School Health Statistic Survey in 2005.

Posterior rotational osteotomy in 48 hips of 40 young patients with femoral head osteonecrosis with extensive and apparent collapsed lesions were reviewed with a mean of 9. No viable area was seen on the articular surface of the femoral head of the loaded portion on preoperative anteroposterior radiographs in all femoral heads. All hips had greater than 3mm collapse; 40 hips showed no apparent joint narrowing, and 8 hips revealed joint narrowing. Posterior viable area of joint surface before surgery ranged from 6% to 29%, with a mean of 19%, on lateral radiographs. Mean postoperative viable area below the acetabular roof was 59% on anteroposterior radiographs and 54% on 45° ﬂexed radio- graphs. Recollapse was prevented in 44 hips (92%), with adequate viable area on the loaded portion on ﬁnal follow-up radiographs. Resphericity of the postoperative transferred medial collapsed area of the femoral head was observed on 34 of 35 hips on ﬁnal anteroposterior radiographs. Posterior rotational osteotomy appeared to be effective in delaying the progression of degeneration in young patients with exten- sive collapsed osteonecrotic lesions.
