[How does oligo- en asymptomatic non-tropical sprue present itself?].

According to the computerized ICD registration, 20 new cases of non-tropical sprue were detected in our outpatient clinic between 1979 and 1990. 8 of these patients had an oligo- or asymptomatic form of this disease (40%). The clinical presentation and spectrum of abnormal laboratory findings in these 8 cases are described in detail. It is concluded that laboratory parameters indicating malabsorption, especially hematologic changes, are helpful for the detection of the oligo- and asymptomatic form of non-tropical sprue, and that, in cases with undetermined anemia, this form of sprue must be considered in etiologic differential diagnosis. Finally, it seems advisable to perform a biopsy as a routine procedure during endoscopy in cases with unclear anemia.

[Effect of halving the dosage of atenolol in essential hypertension].

In the present study the effect of halving the dose of atenolol in 41 essential hypertensives was analyzed. Prereduction dosage of atenolol was 100 mg in 26 and 50 mg in 15 patients. In 16 cases the beta-blocker was administered as monotherapy and in the remaining patients atenolol was combined with a calcium antagonist and/or a diuretic. Dosage of these drugs was constant throughout the whole study. During an observation period of 12 weeks after halving atenolol from a mean dose of 82 mg to 41 mg, no significant changes in systolic and diastolic blood pressure or in response rate (defined as a diastolic blood pressure of 95 mm Hg or less) were observed. In view of our results and those of other authors, it is recommended that in patients with mild hypertension whose blood pressure has been kept below 140/85 mm Hg by treatment for at least one year, betablockers may be reduced in a step-wise fashion.

[Practical and clinical aspects of multifactorial therapy in obesity].

In the present study the effect of a combination of protein-restricted modified hypocaloric diet and a behavioural therapy in 125 obese patients was analyzed. Patients were divided in two groups: 96 patients were instructed and controlled by practitioners (group 1) and 29 patients were followed in our out-patient clinic (group 2). After 14 weeks on diet a mean weight reduction of 10.6 kg in group 1 and of 9.8 kg in group 2 was observed. Furthermore, a significant decrease in systolic and diastolic blood pressure and in mean cholesterol and triglyceride values was seen. Our results show the good effect of a modified protein-sparing fast in obese patients. However, it has to be emphasized that the most promising results have been those utilizing not only a nutritional but also a behavioral approach.

Urinary free cortisol versus 17-hydroxycorticosteroids: a comparative study of their diagnostic value in Cushing's syndrome.

We evaluated the usefulness of the basal urinary 24-h excretion rates of free cortisol versus 17-hydroxycorticosteroids in the diagnosis of Cushing's syndrome. On an outpatient basis, both urinary free cortisol and 17-hydroxycorticosteroids levels were determined in 48 patients with Cushing's syndrome, as well as in 95 obese and 94 healthy control persons of normal weight. Determination of the urinary free cortisol content allowed a clear-cut distinction between the patients with hypercortisolism and the controls, resulting in a sensitivity of 100% and specificity of 98% for the diagnosis of Cushing's syndrome. The diagnostic accuracy of urinary free cortisol was distinctly superior to that of 17-hydroxycorticosteroids, which showed a wide overlap of values between the groups, with a sensitivity of 73% and a specificity of 94%. In conclusion, the measurement of basal urinary free cortisol provided an excellent diagnostic sensitivity and specificity in the assessment of adrenocortical function. This simple and accurate test thus seems to be particularly useful in the outpatient evaluation of patients with suspected Cushing's syndrome.

[Maculopapular rash, pruritus, upper abdominal pain, attacks of dizziness].

A 48 year old male patient presented with maculopapular rash, pruritus, peptic ulcer disease and attacks of headache and vertigo. Rubbing of the cutaneous lesions led to urticarial whealing which is indicative of abnormal mast cell proliferation in the cutis. Histologic evidence of abnormal mast cell proliferation in biopsy specimens of skin and bone marrow led to the diagnosis of systemic mastocytosis. Treatment with H1 and H2 receptor antagonists was started.

[Brain abscess as a complication of Osler's disease with lung involvement].

Eight months after sustaining a reversible left motor hemisyndrome, predominantly of the arm, a 47-year-old man known to have hereditary haemorrhagic telangiectasia (Osler's disease) again developed neurological symptoms (headache, vertigo, unsteady gait) with fever (up to 38.5 degrees C). Clinical features and findings on computed tomography indicated a cerebellar abscess. This was resected because it continued to enlarge despite antibiotic treatment with daily 2 g ceftriaxone and twice daily 0.5 g ornidazole. As another manifestation of Osler's disease further tests revealed an arteriovenous malformation (2.5 x 2.0 cm) in the right upper lobe of the lung, presumably the cause of the cerebral abscess. After wedge resection of the anterior upper lobe segment the further course was without complications.

[Actinomycosis--clinical and therapeutic considerations based on 2 personal case reports].

We report on two patients with actinomycosis. The first case was a 45-year-old cachectic man with extensive bilateral pulmonary infiltrates. The lesions remained unclear for 18 months and only open lung biopsy with microscopic and cultural evaluation led to the diagnosis of actinomycosis. In the second case, classic cervico-facial actinomycosis in a 69-year-old farmer is described. Diagnosis was established on the basis of microscopic findings of "sulphur granules" eroding the mandible. Furthermore, the clinical presentation, with an indurated swelling of the jaw and intraoral fistula formation, was typical. The patient had a severe combined aortic valve lesion and died after ventricular fibrillation during hospitalization. Diagnosis could not be confirmed by culture, probably due to antibiotic prophylaxis against endocarditis during tooth extraction on the first day of admission. Diagnostic difficulties and microbiologic aspects are discussed, with special focus on the rare species of Actinomyces meyeri which was cultured from biopsy specimens from the lung of the first patient. So far this species has been described in only 13 patients.(ABSTRACT TRUNCATED AT 250 WORDS)

[Leg pain, dyspnea].

A 59 year old patient with leg pain and dyspnea was hospitalized for suspected deep venous thrombosis and pulmonary embolism. The clinical, scintigraphic and radiological findings confirmed the diagnosis. Immediate therapy with heparin and oral warfarin resulted in an improvement of pain and dyspnea within a few days. The strategy for diagnostic evaluation of patients with suspected pulmonary thromboembolism is discussed.

[Febrile state, headache and arthralgia].

A 38-year-old man was admitted to the hospital with complaints of persistent fever up to 40 degrees C, arthralgias, headache and a nonproductive cough. The white-cell count was within the normal range but was markedly shifted to the left and demonstrated toxic granulations. Sonographic examination of the abdomen revealed a slight enlargement of the spleen. A nonspecific reactive hepatitis which was clinically asymptomatic was detected by laboratory evaluation. Diagnosis of an acute Q fever was made by demonstration of antibodies against C. burnetii. Following therapy with doxycycline, the patient became afebrile within 48 hours.

[Sources of error in the diagnosis and therapy of hypertension].

Possible errors in the diagnosis and treatment of hypertension are discussed. The problems of blood pressure determinations are reviewed by comparing the results of sphygmomanometry in the doctor's office, of automated ambulatory blood pressure recording and of blood pressure self-measurement. In screening for renovascular hypertension one should be aware that no test is yet available which shows adequate sensitivity and specificity. Therefore, the only investigation that should be used to demonstrate a true stenosis is arteriography. When treating hypertensives it must be kept in mind that the benefits of antihypertensive medication, i.e. reducing morbidity and mortality from cardiovascular disease, should exceed the costs and side effects of the treatment. Finally, the effects of reduction in dose and discontinuation of antihypertensive medication are discussed.

[Thoracic pain, dyspnea].

A 54-year old patient was admitted to the hospital with chest pain, dyspnea and left-sided pleural effusion, which was confirmed by a radiograph of the chest. In view of an exposure to asbestosis a CT scan of the chest was performed, which showed pleural thickening. The suspected diagnosis of a malignant mesothelioma was confirmed by needle biopsy of a paraaortic lymph node. Because of the existence of metastases a palliative pleurectomy was performed. Histologically a malignant mesothelioma of the biphasic type was found. The patient died less than half a year later from local progression of the tumor.

Bronchial neuroendocrine (carcinoid) tumor causing unilateral left-sided carcinoid heart disease.

A female patient suffering from a bronchial neuroendocrine tumor with unilateral left-sided carcinoid heart disease is reported. Repeated x-ray films of the chest showed a slowly growing lung tumor in the left lower lobe. The patient refused any diagnostic or therapeutic procedure to define the type of the tumor. During the follow-up of 24 years she developed severe mitral and moderate to severe aortic insufficiency, both invasively quantified by thermodilution techniques. During surgery for double valve replacement the patient died from left ventricular heart failure. Necropsy revealed the typical pattern of a bronchial neuroendocrine tumor without metastases. Examination of the heart disclosed the characteristic deposits of fibrous tissue on the cusps of both the mitral and the aortic valves whereas the right heart showed no abnormalities. Review of the literature suggests the unilateral left-sided carcinoid heart disease to be a very rare finding, its pathogenesis remains to be elucidated.

[HIV infection and syphilis. Case description and literature review].

Recent case reports emphasize that HIV infection may influence the clinical picture, course and therapy of concurrent syphilis. The case of a 32-year-old patient with coinfection by T. pallidum and HIV is presented. Clinical presentation, diagnostic procedures and therapy are discussed in the light of the current literature. False negative serologic tests for syphilis in HIV-patients raise the question of the sensitivity of these tests in HIV infection. Efficacy of therapy for neurosyphilis and the value of CSF (cerebrospinal fluid) examination in early syphilis are of increased importance in HIV infection. Current guidelines for diagnosis and therapy of syphilis in HIV patients are outlined.

[Fever, somnolence, vomiting, diarrhea].

A 69-year-old female was admitted because of a febrile state, somnolence, nausea and diarrhea. Addison's disease known to have developed several years earlier after adrenal tuberculosis suggested Addisonian crisis triggered by an acute infection. Therapy with steroids and substitution of electrolytes and fluid led to rapid improvement. Streptococcus bovis was identified as causative agent. The known association of this germ with cancer of the colon led to further investigation which revealed cancer of the sigmoid and incidental cancer of a salpinx. After surgical removal of both cancers, the patient has remained free of complaints under substitution of steroids.

[Acute segmental hemorrhagic penicillin-associated colitis].

Four days after beginning a perioperative antibiotic prophylaxis with amoxicillin and clavulanic acid a 33-year-old patient developed an acute haemorrhagic diarrhoea with cramp-like lower abdominal pain. Coloscopy revealed diffuse mucosal oedema with map-like ulcerations, increased susceptibility to trauma and submucous haemorrhages extending from the middle of the ascending to the middle of the descending colon. Granulocytic inflammation with cryptal atrophy was seen histologically. Stool cultures, including tests for Clostridium difficile toxin, were normal. All symptoms disappeared within three days of discontinuing the medication. Coloscopy after one week revealed marked improvement, after three months nothing abnormal. Acute segmental haemorrhagic penicillin-associated colitis is rare and must be distinguished from antibiotic-associated pseudomembranous colitis.

[Diminished vision, loss of libido, headache].

A 34-year old patient was diagnosed to suffer from a carcinoma of the pituitary gland. A developing panhypopituitarism was seen first and the complete extirpation of a chromophobe, non-secreting adenoma of the pituitary gland was preliminary not successful. During half a year the patient relapsed clinically and morphologically by scanning methods and the progression of the malignancy of the tumor from WHO grad (adenoma) to WHO grad III (carcinoma) was histologically confirmed.
