Ultrasound biomicroscopic features of spherophakia

Background: Spherophakia is an uncommon diagnosis. This is the first case report of spherophakia evaluated by ultrasound biomicroscopy.
Methods: Ultrasound biomicroscopy is a new diagnostic technique developed by one of the authors and provides images with microscopic resolution of the anterior segment. A patient with spherophakia was evaluated by ultrasound biomicroscopy (Zeiss-Humphrey, 50MHz) before and after YAG laser iridotomy.
Results: Ultrasound biomicroscopic assessment revealed a shallow anterior chamber, a very steep anterior lens curvature, iridolenticular contact, elongated zonules, and an increased distance between the lens equator and the ciliary processes. Angle closure glaucoma was due to a pupil block mechanism. The pupil block was relieved by YAG laser iridotomy.
Conclusions: Ultrasound biomicroscopy is a useful technique to confirm the diagnosis of spherophakia. The pupil block in spherophakia is relieved by YAG laser iridotomy.     

The importance of the diagnostic imaging of malignant gastrointestinal tumors for radiotherapy]

The importance of diagnostic imaging in malignant gastrointestinal tumors has moved from the primary diagnosis towards staging and follow-up studies. An accurate staging by diagnostic radiology is the cornerstone in planning radiation therapy. Especially in estimating the T- and N-stage as well as the primary diagnosis in esophagus-, gastric and rectal cancer endoscopy with endoscopic ultrasound is the method of choice. When planning radiation therapy barium studies of the esophagus and contrast enema of the colon are important. Only in the case of gastric lymphoma an upper gastrointestinal series is necessary. In the case of suspected recurrent rectal cancer CT-guided biopsy distinguishes between tumor recurrence and reactive fibrosis.     

Coeliac disease, adenocarcinoma of jejunum and in situ squamous carcinoma of oesophagus

The development of both adenocarcinoma of the jejunum and in situ squamous carcinoma of the oesophagus in an adult coeliac patient is described. Good evidence that adenocarcinoma of jejunum occurs more frequently in patients with coeliac disease has recently become available though this association has been suggested for some time. While oesophageal carcinoma has long been associated with coeliac disease, in situ carcinoma of oesophagus has not been previously described in these circumstances. We feel that the risk of this complication, as calculated from published series, warrants a screening programme for oesophageal malignancy in adult coeliacs.
