The CREST syndrome refers to a disorder comprising the manifestations of calcinosis, Raynaud's phenomenon, esophageal dysfunction, sclerodactyly, and telangiectasia. Thirteen CREST patients (two with CRST) were compared with 26 patients with systemic sclerosis but without the full manifestations of the CRST syndrome. No significant difference was found between the groups in the age of onset of Raynaud's phenomenon, degree of multiphasic digital color changes, ulcerations of fingers, sclerodactyly, or in the frequency of abnormal esophageal peristalsis or dysphagia. Laboratory results were similar, including the frequency of an elevated ESR. However, the CREST patients had a significantly lower frequency of arthralgia (54%) and arthritis (15%) than did those with scleroderma (88% and 65%, respectively). All but one of the CREST patients were women, which was a greater proportion than found among scleroderma cases (69%), and all were white (P less than .05). Most patients with the CREST syndrome had rather severe acrosclerosis. At last evaluation, four patients were chronically ill and three had died. The CREST and CRST syndromes are closely related disorders that seem to be part of the spectrum of systemic sclerosis.

Motor function disturbances (MFD) of the esophagus occur in the majority (90%) of patients with systemic sclerosis. We have tested the diagnostic value of esophagus scintigraphy in 20 patients with systemic sclerosis (12 CREST and 8 with diffuse form) and 18 controls (11 normals and 7 with pyrosis and/or regurgitation), in order to establish sensitivity, specificity, effects of body posture, and use of a liquid or solid meal in the evaluation of MFD of the esophagus. The patients drank 4 ml of fruit juice marked with 500 microCi of 99mTc-sulfur-colloid and afterwards 10 g of an equally marked and scrambled egg. Pictures were made with a Gamma-Camera until 180 s. Radioactivity was plotted against time and separately analysed for the upper, middle and distal esophagus. 65% of the systemic sclerosis patients had dysphagia and 70% had abnormal barium meal transit in the esophagus. The scintigrams were altered in all the patients with systemic sclerosis (p less than 0.001). Sensitivity using fluids was 95%, and specificity was 89%; with solid food 100% and 50%, respectively. Tests done in the upright position showed a better clearance of the esophagus in patients with systemic sclerosis and control patients, with loss of sensitivity. The qualitative analysis yielded little benefit to the reported results. The quantitative analysis under use of 2 indices (total transit time and clearance rate) permitted a clear distinction among patients and control individuals with and without upper digestive symptoms in the first 15 s of the test. The esophagus scintigraphy is a simple, quantitative and very sensitive method for the diagnosis of MFD of the esophagus in patients with systemic sclerosis.

Cineradiography of the esophagus showed signs of esophageal candidiasis in 11 out of 71 patients with progressive systemic sclerosis (PSS) - both in diffuse scleroderma and the CREST syndrome. Culture of esophageal brushings confirmed the presence of Candida albicans in eight of these 11 patients. Antimycotic treatment decreased the cineradiographic signs of candidiasis and the degree of dysphagia. Since impaired esophageal motility and treatment with immunosuppressive drugs may predispose to candida esophagitis, and since dysphagia will decrease after antimycotic treatment esophageal mycosis should always be sought in patients with PSS.

Gastroesophageal reflux is well documented in scleroderma, but the complications of Barrett's metaplasia and adenocarcinoma are not well described. The records of 75 patients with scleroderma seen over a four-year period at the Hospital of the University of Pennsylvania were retrospectively reviewed to determine the prevalence of Barrett's metaplasia and adenocarcinoma of the esophagus and to identify clinical, manometric, laboratory, or radiographic criteria that might predict the presence of these lesions. Twenty-four of these patients underwent endoscopy. In this group, the prevalence of Barrett's metaplasia was 37 percent (nine patients) and adenocarcinoma was also present in two of these patients. The patients with and without Barrett's metaplasia were similar in age (range, 22 to 64 compared with 28 to 79, respectively), sex (six of nine compared with 12 of 15 female, respectively), frequency of esophageal motility disorders, presence of proximal skin involvement, digital ulceration, and pulmonary involvement as measured by diffusion capacity. Barrett's metaplasia was diagnosed on the basis of double-contrast esophagographic results in only one of eight patients with Barrett's metaplasia so-studied. Patients with Barrett's metaplasia tended to have longer duration of heartburn (90 +/- 40 months compared with 11 +/- 35 months) and dysphagia (39 +/- 22 months compared with 7 +/- 3 months). Patients with Barrett's metaplasia also tended to have greater impairment of lower esophageal sphincter pressure either at end-expiration (4.0 +/- 2.1 compared with 6.1 +/- 1.8 mm Hg) or mid-respiration (13.0 +/- 3.0 compared with 16.9 +/- 2.5 mm Hg). Using chi-square analysis, however, none of these differences reached statistical significance. Discrimination did occur on the basis of the presence of the CREST (calcinosis, Raynaud's phenomenon, esophageal manifestations of scleroderma, sclerodactyly, and telangiectasis) variant (55 percent compared with 7 percent, p less than 0.01), a duration of dysphagia of more than five months (p less than 0.03), and mid-respiratory lower esophageal sphincter pressure of less than 10 mm Hg (p less than 0.05). It is suggested that: Barrett's metaplasia of the esophagus occurs in one third of patients with scleroderma; clinical, manometric, laboratory, and radiographic features are poor predictors of the presence of Barrett's metaplasia; patients with CREST syndrome, prolonged dysphagia, or a very low lower esophageal sphincter pressure may have an increased risk for the development of metaplasia; patients with scleroderma and Barrett's metaplasia have an increased risk of complications such as stricture or adenocarcinoma.(ABSTRACT TRUNCATED AT 400 WORDS)

Thirty-three patients with progressive systemic sclerosis (PSS) (24 women and 9 men, 27 with diffuse scleroderma and 6 with CREST syndrome) were treated with griseofulvin alone (375-500 mg/day) for 12-84 months (mean 33). Clinical and functional assessment of the results included: a self-evaluation (general status, skin toughness, cold sensitivity, dysphagia), a physical examination (fingerprint areas, chest expansion, mouth widening, grip strength) routine laboratory tests, electrocardiogram, glomerular filtration rate (GFR), esophagus and chest X-rays. After griseofulvin, a significant improvement was noted in 28/33 patients (85%) regarding subjective condition and skin thickening and elasticity, particularly in the trunk and proximal limbs (p less than 0.05 for chest expansion), and of GFR (p less than 0.01). Lung and esophageal involvement, on the whole, remained unchanged during the treatment, which does not appear to modify the progression of PSS myocardiopathy. No patient stopped using griseofulvin because of side effects. The present results show that griseofulvin is a safe drug for PSS treatment and that it can influence the skin and renal involvement.

Nineteen patients with systemic sclerosis, including two with CREST syndrome variant, were clinically evaluated for oral and gingival manifestations of their disease. Subjectively over 50% complained of xerostomia, limited opening, recurrent "mouth sores" and dysphagia. Four patients indicated that they had been refused dental care due to limited accessibility to the oral cavity. Objectively, physical examination disclosed prominent lingual and buccal mucosal crenations and loss of tongue mobility with fibrotic induration in 25% of the subjects examined. Three of the patients with advanced disease exhibited foci of severe gingival recession due to fibrous strictures and attached gingiva stripping. None of the patients showed any indication of uncontrolled dental disease secondary to xerostomia.

Lower esophageal rings were found in five of 40 consecutive patients seen with progressive systemic sclerosis. Three of these five patients had diffuse skin involvement and two had the CREST variant of progressive systemic sclerosis. All of the patients with lower esophageal rings had intermittent esophageal obstruction (initially attributed to esophageal dysmotility), but so did five of seven patients with esophageal strictures without lower esophageal rings. Esophageal bougienage relieved this symptom in four of the five patients with rings in which it was performed. Persistent relief of these obstructive symptoms (6-36 months) in the patients with rings was in contrast to the recurrent dilatations that have been needed in the group of patients with peptic strictures. In contrast to esophageal aperistalsis and/or stricture formation, the lower esophageal ring, perhaps as a consequence of chronic gastroesophageal reflux, may be a more treatable cause of dysphagia in patients with progressive systemic sclerosis.

We report a case of oesophageal disease as the first manifestation in a patient with CREST syndrome. A 46-year-old man with achalasia-like syndrome developed CREST syndrome 4 years later. A pneumatic dilatation of the cardia was performed. After pneumatic dilatation the dysphagia and regurgitation disappeared but the patient developed reflux oesophagitis. Four years after diagnosis of oesophageal disease he presented with a clinical picture of CREST syndrome. An acute ileus and constipation developed later. After receiving medical therapy with omeprazole and cisapride the patient is free of oesophageal symptoms and bowel movements are normal. Oesophageal disease is common in patients with limited and diffuse scleroderma, but to our knowledge achalasia-like syndrome has not been previously described as the first manifestation of the systemic disease.

Our aim was to review the use of esophageal investigations in patients with suspected connective tissue disease (CTD). Forty-seven patients (39 women and 8 men) with suspected CTD were referred for esophageal manometry at the gastrointestinal physiology unit in the Royal Victoria Hospital, Belfast, U.K., over a 10-year period (1987-1997). The mean age was 51.7 years (range = 21-79 years). Chart review was conducted 1 to 10 years after manometry to confirm the final diagnoses: scleroderma was found in 11; CREST (calcinosis, Raynaud's phenomenon, esophageal dysmotility, sclerodactyly, telangiectasia), 8; mixed connective tissue disease, 14; Raynaud's alone, 5; and other CTDs, 9. All 47 successfully underwent esophageal manometry. In addition to manometry, 24 underwent gastroscopy; 27, barium meal; and 3, esophageal pH studies. Clinically significant esophageal abnormalities were noted in 8 (33%) on gastroscopy, in 15 (56%) on barium meal, and in 31 (66%) on manometry. Gastroscopy had a significantly lower positivity rate than the others (p < 0.05). Only three patients had pH testing, yet all three pH tests were abnormal. During manometry, abnormal findings were significantly more common in scleroderma-CREST when compared with other diagnoses (89% vs. 50%; p < 0.02). Thirty-three patients reported dysphagia. Abnormal manometry was more likely in these cases (82% vs. 33%; p < 0.02). A high percentage of patients with CTD have significant esophageal motility disorders. Investigations were more likely to be positive with scleroderma-CREST than other CTDs, even if dysphagia was present. Barium meal and manometry are more useful than OGD. pH studies were under-used. There is need for a standardized approach to esophageal investigations in patients with CTDs.

We report a severe unilateral recurrent laryngeal nerve neuropraxia following use of the ProSeal laryngeal mask airway (PLMA) in a 71-year-old female patient with CREST syndrome. She required amputation of the 5th phalanx of foot because of gangrene due to Raynaud's syndrome. Anesthesia was induced with propofol, and a size 3 PLMA was inserted. Anesthesia was maintained with sevoflurane and nitrous oxide for 2 h and the operation was performed uneventfully. On removal of PLMA, the cuff volume was measured to 40 ml. The patient did not complain of respiratory discomfort shortly after PLMA removal. However, the next day she developed dysphagia and hoarseness. Laryngoscopic examination revealed unilateral vocal cord paralysis. Cricothyrotomy was required because of suspected silent aspiration pneumonia. The pharyngolaryngeal complications improved with a mobile vocal cord but slight hoarseness after 2 months. We considered the patient's CREST syndrome with a potential of tissue ischemia, and the high intracuff pressure of the PLMA due to nitrous oxide influx, to be the cause of severe recurrent laryngeal nerve neuropraxia in this case.
