Tourette's syndrome: a treatable tic.

Tourette''s syndrome, or Gilles de la Tourette''s disease, is a disorder characterized by involuntary tic-like muscular movements, compulsive behaviour and involuntary vocalization of sounds, words or profanities. It begins in childhood and may persist for life, with a varied pattern and course. Recent studies indicate an organic basis for the disorder, and an abnormality of dopamine or purine metabolism has been suggested. The treatment of choice is haloperidol administration; most patients do well with low or moderate doses for long periods. Because these patients are often mistakenly regarded as anxious, psychoneurotic or hysterical, correct diagnosis is important if they are to be treated appropriately and regarded properly in the home, school and society.     

Disgust implicated in obsessive-compulsive disorder.

Psychiatric classificatory systems consider obsessions and compulsions as forms of anxiety disorder. However, the neurology of diseases associated with obsessive-compulsive symptoms suggests the involvement of fronto-striatal regions likely to be involved in the mediation of the emotion of disgust, suggesting that dysfunctions of disgust should be considered alongside anxiety in the pathogenesis of obsessive-compulsive behaviours. We therefore tested recognition of facial expressions of basic emotions (including disgust) by groups of participants with obsessive-compulsive disorder (OCD) and with Gilles de la Tourette''s syndrome (GTS) with an without co-present obsessive-compulsive behaviours (GTS with OCB; GTS without OCB). A group of people suffering from panic disorder and generalized anxiety were also included in the study. Both groups with obsessive-compulsive symptoms (OCD; GTS with OCB) showed impaired recognition of facial expressions of disgust. Such problems were not evident in participants with panic disorder and generalized anxiety, or for participants with GTS without obsessions or compulsions, indicating that the deficit is closely related to the presence of obsessive-compulsive symptoms. Participants with OCD were able to assign words to emotion categories without difficulty, showing that their problem with disgust is linked to a failure to recognize this emotion in others and not a comprehension or response criterion effect. Impaired recognition of disgust is consistent with the neurology of OCD and with the idea that abnormal experience of disgust may be involved in the genesis of obsessions and compulsions.     

Cushing's syndrome in childhood

A patient with Cushing''s syndrome whose clinical manifestations began at approximately 9 years of age was followed for a period of four years. Initial laboratory studies revealed urinary 170HCS and 17 KS levels which were elevated for her age, with a normal diurnal variation of plasma cortisol and normal suppression of urinary 170HCS by 1.5 mg. of dexamethasone daily. It was not until four years after the onset of the disease that laboratory studies unequivocally supported the diagnosis of Cushing''s syndrome resulting in definitive therapy. Clinical features consisted primarily of cessation of growth, obesity, and hirsutism, with no evidence of protein depletion. It is suggested that the clinical and laboratory features of Cushing''s syndrome in childhood may present differences from those found in the adult. Failure to recognize these differences may result in delay in therapy with subsequent persisting stigmata of the disorder.     

The XXXXY Chromosome Anomaly: Report of Three New Cases and Review of 30 Cases from the Literature

The majority of abnormal sex chromosome complexes in the male have been considered to be variants of Klinefelter''s syndrome but an exception should probably be made in the case of the XXXXY individual who has distinctive phenotypic features. Clinical, radiological and cytological data on three new cases of XXXXY syndrome are presented and 30 cases from the literature are reviewed. In many cases the published clinical and radiological data were supplemented and re-evaluated. Mental retardation, usually severe, was present in all cases. Typical facies was observed in many; clinodactyly of the fifth finger was seen in nearly all.Radiological examination revealed abnormalities in the elbows and wrists in all the 19 personally evaluated cases, and other skeletal anomalies were very frequent. Cryptorchism is very common and absence of Leydig''s cells may differentiate the XXXXY chromosome anomaly from polysomic variants of Klinefelter''s syndrome. The relationship of this syndrome to Klinefelter''s syndrome and to Down''s syndrome is discussed.     

Adrenocortical Hyperfunction Associated with Bronchogenic Carcinoma: Report of Five Cases

Five patients with bronchogenic carcinoma associated with adrenocortical hyperfunction are described. The clinical features, laboratory studies and autopsy findings are discussed and compared with previously reported cases. Four patients presented most of the typical features of this disorder as previously described, whereas the fifth was atypical in some respects. Typical features included: acute onset of adrenocortical hyperfunction in a middle-aged male, rapid downhill course, slight or absent physical signs of Cushing''s syndrome, frequently impaired glucose tolerance, markedly elevated plasma and urinary 17-hydroxycorticosteroids not suppressed by exogenous steroids, absent diurnal variation of plasma corticoids, hypokalemic alkalosis with normal aldosterone excretion, and tumour histology of the oat cell variety. The adrenal glands of two patients were of normal or slightly increased weight, and mean 17-ketosteroid excretion values were normal in three; this contrasts with the marked increase in adrenal weight and 17-ketosteroid excretion in most reported cases.     

Marfan's Syndrome: The S. Family Re-visited

Marfan''s syndrome has been transmitted by a single pleiotropic autosomal gene through six generations of a Canadian family. At least 42 members of this family have been affected to date. The natural history of this inherited affliction in this family supports the hypothesis that Marfan''s syndrome is an abiotropic disorder of the connective tissues. Premature degeneration of the connective tissues is responsible for the serious ocular and cardiovascular complications of Marfan''s syndrome, for the shortened life span of affected individuals, and indirectly, for the economic distress of affected members of this family. Because no definitive treatment is available for Marfan''s syndrome, an educational approach to the restriction of child-bearing by affected individuals is proposed.     

Dr Samuel Johnson's movement disorder.

Dr Samuel Johnson was noted by his friends to have almost constant tics and gesticulations, which startled those who met him for the first time. He also made noises and whistling sounds; he made repeated sounds and words and irregular or blowing respiratory noises. Further, he often carried out pronounced compulsive acts, such as touching posts, measuring his footsteps on leaving a room, and performing peculiar complex gestures and steps before crossing a threshold. His symptoms of (a) involuntary muscle jerking movements and complex motor acts, (b) involuntary vocalisation, and (c) compulsive actions constitute the symptom complex of Gilles de la Tourette syndrome (Tourette''s syndrome), from which Johnson suffered most of his life. This syndrome is of increasing interest recently because it responds to haloperidol, and because there are new insights into a possible biochemical basis for the tics, vocalisations, and compulsions.     

Otolaryngological Aspects of Sj?gren's Syndrome

Twenty-two patients with Sjögren''s syndrome uncomplicated by a connective tissue disorder, 31 with Sjögren''s syndrome complicated by rheumatoid arthritis, and 21 with rheumatoid arthritis alone were studied with particular reference to changes in the ears and in the upper respiratory and digestive tracts.Epistaxis, soreness and dryness of the throat, dysphagia, and hoarseness were common symptoms, and rhinitis sicca and postcricoid narrowing were not uncommon features of the Sjögren groups. Oesophagoscopy in one patient revealed a web identical to that found in Paterson/Brown Kelly syndrome; none of the patients, however, had an iron-deficiency anaemia or koilonychia. There was an increased frequency of deafness in all groups, and the deafness tended to be conductive in the Sjögren groups and sensorineural in the rheumatoid arthritis group.     

Unusual clustering of diseases in a Canadian Old Colony (Chortitza) Mennonite kindred and community.

We investigated a large Old Colony (Chortitza) Mennonite kindred with branches across Canada. Six generations of the kindred were traced. There was intermarriage among numerous family members. Insulin-dependent diabetes mellitus (IDDM) was identified in 10 members; all 7 living patients were found to carry the immunogenetic marker HLA-DR4. Nine other close relatives had disorders of carbohydrate metabolism, including gestational diabetes mellitus and non-insulin-dependent diabetes mellitus progressing to insulin use. Ten other relatives had autoimmune diseases, including rheumatoid arthritis, hyperthyroidism, hypothyroidism and multiple sclerosis. Cases of Alport''s syndrome, congenital malformations, inborn errors of metabolism and unusual malignant diseases were also found in the kindred. In the small Alberta community in which the kindred was ascertained there were people of Old Colony Mennonite descent with genetic conditions such as Gilles de la Tourette''s syndrome and congenital malformations, including congenital heart disease. This kindred represents the largest reported familial aggregation of IDDM. This disease and other disorders of carbohydrate metabolism occur in the context of a strong familial predisposition to autoimmune disease. Study of this family may permit empiric testing of proposed models of inheritance of diseases of complex origin such as IDDM. We report this Old Colony (Chortitza) Mennonite community because it is one of the settlements populated by this religious and genetic isolate, which extends across Canada and Central and South America and affords opportunities for the study of both common and rare inherited diseases.     

Waardenburg's Syndrome and Heterochromia Iridum in a Deaf School Population

Waardenburg''s syndrome consists of lateral displacement of the inner canthi of the eyes (dystopia canthorum), a broad nasal root and confluent eyebrows, heterochromia iridum, a white forelock and congenital deafness. The syndrome is inherited as a dominant, but affected individuals do not necessarily have all of the characteristics cited.Five hundred and fourteen pupils at a school for the deaf were screened for features of this syndrome. Three cases were discovered. Eleven other deaf children were found to have heterochromia iridum and two more had white forelocks. The interocular dimensions of the remaining children were recorded as standards by which to judge the presence of dystopia canthorum. The results of chromosomal analysis in two cases with Waardenburg''s syndrome were normal.The findings provide further evidence that Waardenburg''s syndrome is a distinct entity and call in question Mackenzie''s concept of a comprehensive “first arch syndrome”.     

Unexplained left ventricular hypertrophy: consider a diagnosis of Fabry's disease

Lysosomal storage disorders are a group of disorders characterised by the deficiency of a specific lysosomal hydrolase. These diseases are rare, with only a few hundred patients in the Netherlands. Fabry''s disease, an X-linked lysosomal storage disorder, is caused by a deficiency of the lysosomal enzyme α-galactosidase A which results in, among other things, left ventricular hypertrophy, renal failure and cerebrovascular events. Patients with Fabry''s disease, especially males, have a decreased life expectancy. Recent studies have shown that Fabry''s disease may be much more common among patients with left ventricular hypertrophy (LVH) than previously thought. Up to 7% of male patients with left ventricular hypertrophy and up to 12% of female patients with unexplained LVH were found to suffer from Fabry''s disease. Thus, Fabry''s disease should be considered in patients with unexplained LVH. This case report summarises the main features of the disease. In addition recent developments concerning prevalence, diagnosis and the current available treatments are discussed and an algorithm on who and how to screen for Fabry''s disease is presented.     

A case of membranous lipodystrophy complicated by Fanconi's syndrome

A case of membranous lipodystrophy complicated by Fanconi's syndrome is described. A 40-year old man complaining of pain in his legs was admitted to our hospital. Roentgenograms showed cystic changes in the long bones. Biopsy of the affected lesion of the femur revealed a peculiar membranocystic structure in the marrow that is typical of membranous lipodystrophy. He had a neuropsychiatric disorder which is often associated with this disease. Laboratory studies were remarkable for renal proximal tubular dysfunction., i.e., Fanconi's syndrome. Membranous lipodystrophy is a rare, hereditary disease that has been reported mainly from Japan and Finland. This is the first case of this disease complicated by Fanconi's syndrome. The possible relationship between these disorders is discussed.     

De Lange Syndrome: Report of 20 Cases

Typus Degenerativus Amstelodamensis or Amsterdam dwarfism, a syndrome of unknown etiology characterized by mental retardation, a distinctive face, characteristic hands and feet, defective growth and other minor malformations, was first described by Cornelia de Lange in 1933. Approximately 69 cases, including nine autopsies, have been reported in the literature. In this paper we present a further 20, with illustrations of the syndrome from infancy to puberty (including de Lange''s original three cases). The historical, physical, laboratory and radiographic findings of de Lange''s three patients and our 20 are tabulated. Autopsy findings in one of our patients are reported and the literature is briefly reviewed.Although some observers have recently reported chromosome abnormalities in de Lange''s syndrome, we feel that the diagnosis is made from the history and physical examination and that there are no definitive laboratory aids which can confirm the diagnosis. Chromosome studies in all 20 of our patients were normal and the genetic implications are discussed.     

A case of Kartagener's syndrome: Importance of early diagnosis and treatment

Kartagener''s syndrome is a very rare congenital malformation comprising of a classic triad of sinusitis, situs inversus and bronchiectasis. Primary ciliary dyskinesia is a genetic disorder with manifestations present from early life and this distinguishes it from acquired mucociliary disorders. Approximately one half of patients with primary ciliary dyskinesia have situs inversus and, thus are having Kartagener syndrome. We present a case of 12 year old boy with sinusitis, situs inversus and bronchiectasis. The correct diagnosis of this rare congenital autosomal recessive disorder in early life is important in the overall prognosis of the syndrome, as many of the complications can be prevented if timely management is instituted, as was done in this in this case.     

The Restless Leg Syndrome

The author reviews and provides examples of the restless leg syndrome (Ekbom''s syndrome), emphasizing the frequency of the disorder and its distressing symptoms. The syndrome is characterized by a creeping, crawling sensation in the lower legs, usually at night. It is accompanied by an irresistible urge to move the legs, and this movement eventually relieves the symptoms. It is found in 5% of the general population, with a higher incidence in pregnant women and people with anemia, but no vascular, neurological or other abnormalities are found on examination. Patients are treated empirically with vasodilators or intravenous iron. The etiology is unknown.     

Atlantoaxial dislocation and Down's syndrome.

The phenotypic features of Down''s syndrome are easily recognized and include characteristic facial features, hypotonia, ligament laxity, transverse palmar creases and mental subnormality. Associated manifestations and complications are also familiar and involve almost every organ system. Congenital heart defects, bowel malformations and a tendency to leukemia are common attendant problems. Less common, however, are defects of the skeletal system; in fact, the most recent edition of a standard pediatric textbook makes no mention of anomalies of the vertebral column. The purpose of this paper is to call attention to the association between Down''s syndrome and atlantoaxial dislocation, which in our patient resulted in quadriplegia and eventually death.     

Measurement of activity of urea resistant neutrophil alkaline phosphatase as an antenatal screening test for Down's syndrome.

OBJECTIVE--To investigate the value of measuring maternal urea resistant neutrophil alkaline phosphatase activity as an antenatal screening test for Down''s syndrome. DESIGN--Case-control study of blood samples collected at nine to 27 weeks of pregnancy. SETTING--Antenatal clinics in London and Oxford. PATIENTS--72 Women whose fetuses had been diagnosed by amniocentesis or chorionic villus sampling as having Down''s syndrome and 156 women whose fetuses did not have the syndrome. Only singleton pregnancies were studied. MAIN OUTCOME MEASURE--Activity of urea resistant neutrophil alkaline phosphatase measured cytochemically. RESULTS--The median enzyme activity in the index patients was 1.65 times the expected median for the controls at the same duration of pregnancy (p less than 0.0001; 95% confidence interval 1.56 to 1.74). A cut off value that identified the 5% of control patients with the highest activities yielded a rate of detection of Down''s syndrome of 79% (95% confidence interval 70 to 89%). CONCLUSION--Activity of urea resistant neutrophil alkaline phosphatase is an effective maternal blood marker for Down''s syndrome. Its use in antenatal screening could lead to a substantial improvement in the detection of this disorder. Before introducing the test into routine medical practice it will have to be automated so that it can be used on a large scale and is less subjective.     

Islet-cell Carcinoma (Zollinger—Ellison Syndrome) with Fulminating Adrenocortical Hyperfunction and Hypokalemia

The production of ACTH-like material by tumours arising in non-endocrine tissue may initiate severe adrenocortical hyperfunction. The pathogenesis and clinical and laboratory features of Cushing''s syndrome associated with such tumours are characteristic. The autonomous production by the tumour of ACTH-like material cannot be suppressed by exogenous corticoids. The onset of clinical symptoms is rapid; muscle wasting, general weakness, thirst and peripheral edema predominate, and the classical signs of Cushing''s syndrome may be absent. High levels of plasma 17-hydroxycorticosteroids and urinary 17-hydroxycorticosteroids and 17-ketosteroids, usually with normal levels of urinary aldosterone, commonly occur. Hypokalemic alkalosis unresponsive to replacement therapy may cause death. In the case reported herein, the intriguing possibility exists that two hormone-like substances were produced by the primary growth and its metastases: one, ACTH-like, to account for the adrenal hyperplasia and Cushing''s syndrome; and another, gastrin-like, giving rise to the ulcerogenic diathesis.     

Sj?gren's Syndrome

Sjögren''s syndrome is a common accompaniment of rheumatoid arthritis and other connective-tissue diseases as well as several diseases thought to have an immunological basis. Despite the wide spectrum of clinical features and serological abnormalities the condition is, if anything, underdiagnosed. A clinical subgroup of patients with Sjögren''s syndrome can be distinguished by their pronounced hypergammaglobulinaemia, widespread and prominent immunological abnormalities, severe salivary gland swelling, and mild or absent arthritis. It is in this group that lymphoma development has been a complication.     

The de Lange Syndrome: Report of Three Cases

Three cases of de Lange''s syndrome are described. This condition is characterized by generally severe mental retardation, reduced stature, mild microcephaly, hypertrichosis, various anomalies of hands and feet, and a peculiar facies. The most outstanding features of the latter are the low forehead, profuse, generally confluent eyebrows, abundant long eyelashes, eyes that frequently slant downwards and outwards in antimongoloid fashion, pug nose with prominent anteverted nostrils, increased distance between nose and vermilion border of upper lip, slight reduction in size of chin, and often abnormally low-placed ears. The etiology of de Lange''s syndrome is at present unknown.
