A 35-year-old male who had travelled extensively in the tropics presented with severe anorexia and vomiting associated with fever of 39-40 degrees C during a 4-day period. The clinical findings were entirely negative. In 1973, he had been given metronidazole for amebic dysentery, since when recurrent attacks of diarrhea and abdominal pain had been treated with iodoquinoleines. Stool examination was negative for amebae. Liver scan revealed a suspect "expansive process" in the right lobe. The presumptive diagnosis of amebic abscess was made and metronidazole therapy was started. In less than 24 h the patient became afebrile. The abscess was confirmed by a further liver scan. The definitive diagnosis of amebiasis was established 16 days later when the immunofluorescence level, which had been previously negative, became positive 1/480. This case demonstrates the dangers of the indiscriminate use of iodoquinoleines in patients who have travelled in tropical countries. The amebic liver abscess may be silent locally while causing systemic manifestations such as fever. Early treatment of hepatic amebiasis is recommended even with a presumptive diagnosis. Serological tests during the development of an amebic abscess may be negative and should be repeated after several days of therapy. 相似文献

In general, malignancies presenting as abscesses are uncommon. We report on a patient that presented with a neck abscess originating in a cluster of metastatic lymph nodes from a primary squamous cell carcinoma arising in the thoracic oesophagus. 相似文献

Partial avulsion of the middle turbinate is an unusual complication of nasotracheal intubation while minor nasal mucosal trauma is not uncommon. Nasal turbinate avulsion often presents with persistent epistaxis but in the case reported, unilateral nasal obstruction with minimal epistaxis was the presenting feature. Unilateral nasal obstruction following nasotracheal intubation should raise suspicion of significant disruption of the intranasal architecture. 相似文献

A 2-year-old child was admitted with bilateral bronchopneumonia. During convalescence he sustained sudden respiratory arrest for which he required ventilatory support. He had undergone cholecystectomy 1 month prior to the above episode. The pathological examination of the gall bladder mass had revealed the features of metachromatic leukodystrophy. Gastro-oesophageal reflux, which is associated with this neurological disorder, was suspected to be the cause of this sudden respiratory arrest and its presence was confirmed by barium swallow examination. 相似文献

Tracheoesophageal fistula (TEF) without atresia is rare and usually presents with symptoms from birth. In this report, a 9-year-old boy presented with productive cough of 4 month's duration and was shown to have a right lung abscess seen on chest radiograph. His parents denied earlier respiratory symptoms or illnesses. Rigid bronchoscopy showed a fistulous opening of about 1 mm in diameter in the posterior wall of the trachea about 16 cm from the upper incisor teeth. Cannulation with a ureteral catheter demonstrated that the fistulous opening communicated with the esophageal lumen. The tracheoesophageal fistula was 1 cm long and was divided through a right supraclavicular incision. The postoperative period was uneventful, and the patient was discharged on the third postoperative day. This case demonstrated that TEF should be considered in any patient presenting with chronic respiratory problems even after a prolonged symptom-free period. 相似文献

One case of allergic contact dermatitis caused by polyvinyl chloride identification bands is reported. Patch tests in this case were positive for three of four bands tested, resorcinol monobenzoate, and benzoyl peroxide. Manufacturers could not confirm the presence of resorcinol monobenzoate and benzoyl peroxide in their respective bands. It is concluded that the patient's reaction was allergic and due to an unknown chemical(s) in the bands. Additives may comprise a significant portion of polyvinyl chloride bands. These components may be leachable, and thus lead to contact sensitization with subsequent allergy. Although patch testing is an excellent first step in determining the offending allergen, specialized chemical analysis may be required for exact identification. 相似文献

Red cell and haemoglobin values in 44 women with a typical picutre of anorexia nervosa showed that 20.5% presented a picture of true anaemia. Blood iron was low, sometimes very low, with a mean value of 66 mg 0/0. Clotting parameters: PTT, TT, PT, circulating platelets and TEG were normal. This finding serves to explain the low incidence of haemorrhage and the ready haemostasis noted in this disease, in spite of the considerable food deficit. 相似文献

A case is reported of oat cell carcinoma of the lung presenting with unusual sites of metastasis to the orofacial region. Distant metastases are common in oat cell carcinoma but a literature review did not reveal any reports of metastases either to the hard palate or to medial canthus of the eye. 相似文献

A variety of reconstructive procedures have been suggested for stabilizing the ulnar shaft following resection of the distal ulna for tumour. We present the results of a series of nine distal ulnar tumour resections in which four different stabilization techniques were employed. We based our results on an evaluation of function, pain, motion, strength and instability. We obtained good or excellent results in seven patients treated with a soft tissue stabilization of the ulnar stump. One patient did not undergo any stabilization procedure and scored fair in our system. A further patient who required a radiocarpal arthrodesis also had an inferior result. These results suggest that soft tissue stabilization of the ulnar stump should be performed whenever possible. 相似文献

A case of esophageal perforation occurring in a 75-year-old man is presented. The clinical presentation was benign and the diagnosis of esophageal perforation was made incidental to an upper gastrointestinal barium examination. Conservative management consisting of nasogastric suctioning, antibiotics and antacids was effective in minimizing the clinical course. This represents a rare instance of a successful nonsurgical approach to esophageal perforation. 相似文献

We report a newborn in whom multiple small congenital melanocytic nevi (MN) were noted on the right side involving the scapular area, shoulder, upper arm and forearm. Such a limb distribution of small congenital MN has never been reported in the literature. 相似文献

We report an unusual presentation of orofacial actinomycosis mimicking the clinical appearance of a minor salivary gland tumour of the upper lip. Histological examination confirmed the diagnosis and we think that the lesion was caused by infection of a mucocele of the upper lip by Actinomyces israelii, an oral commensal. 相似文献

The case of a 37 year old woman with hypoparathyroid congestive heart failure (CHF) is reported. Thyroidectomy had been performed eight years earlier and she had experienced symptoms of hypocalcemia postoperatively. CHF improved rapidly and completely with the treatment of hypocalcemia. Good prognosis is emphasized but it is necessary to think about this cause of ventricular dysfunction in a patient with CHF and a history of neck surgery in order to make an early diagnosis. Pathogenic mechanisms and differential diagnosis are discussed. 相似文献

Polymorphism of factor H (HF) was investigated in 1060 unrelated Japanese individuals using isoelectric focusing and immunoblotting. Besides 6 different HF types a null type and an unusual type were observed. The family analysis suggested the hereditary occurrence of a new variant allele HF*C. The population data fitted the Hardy-Weinberg equilibrium, assuming that the null allele HF*QO occurs commonly. The allele frequencies were HF*A = 0.407 +/- 0.011, HF*B = 0.491 +/- 0.011, HF*A1 = 0.011 +/- 0.002 and HF*QO = 0.091 +/- 0.006. The HF polymorphism in Japanese was shown to be controlled by the above 4 common alleles. 相似文献
