The electro-oculogram in uveal melanoma

The electro-oculogram in 52 patients with a suspected malignant melanoma of the choroid or ciliary body was plotted in a diagram constructed for the differential diagnosis of malignant melanoma, metastasis, naevus and retinal detachment. Thirty-one patients were diagnosed as suffering from malignant melanoma on clinical grounds (19 histologically confirmed). Twenty-six were classified correctly as a melanoma using our EOG probability score. Rupture of Bruch's membrane and tumor localization were of no influence on the EOG classification. Accompanying retinal detachment lowered the Lp/Dt-ratio significantly without affecting the Dt, as was also the case in tumors with a prominence equal to or greater than 6mm when compared with smaller tumors. However melanomas were still classified correctly in the majority of the patients by means of EOG. We conclude that an acceptable differentiation can be made between melanomas, retinal detachments and naevi. Melanomas cannot be differentiated from choroidal metastases.     

Endosonography in diagnosing and staging duodenal villous adenoma.

Endosonography was carried out in a patient with an extensive juxtapapillary tumour. Radiology and endoscopy were unable to distinguish a villous adenoma from an invasive carcinoma. Endosonography revealed a mucosal hypoechoic tumour without penetration into the submucosa and muscularis propria. The common bile duct, pancreatic duct, and pancreas were normal. Lymph node abnormalities were not found. Based on the endosonography findings, local surgical tumour resection was undertaken instead of a Whipple procedure. The histology of the resected specimen confirmed the endosonography diagnosis.

A double or bilobar gallbladder as a cause of severe complications after (laparoscopic) cholecystectomy

A double or bilobar gallbladder is a rare congenital anomaly. If not recognized during preoperative evaluation or operation, it can cause severe complications. We describe two cases in which a second operation had to be performed because of the presence of a second or bilobar gallbladder that was not recognized in the preoperative evaluation and during (laparoscopic) cholecystectomy. The types of anomalies, the concomitant pathology, and treatment are discussed.     

Neuromuscular hyperexcitability features in patients suffering from musculoskeletal pain: a neuroepidemiologic survey.

We studied the reported frequencies of clinical complaints of neuromuscular hyperexcitability (muscle cramps and fasciculations) in random samples of 527 Dutch adults, who were and 253 Dutch adults, who were not suffering from musculoskeletal pain and tenderness. Data were collected by telephone-interview and by self-administered questionnaire. Muscle cramps and fasciculations were recorded more frequently in the category that suffered from musculoskeletal pain (p less than 0.001). This association warrants further investigation into the possible intrinsic role of neuromuscular hyperexcitability in musculoskeletal pain and primary fibromyalgia.
