Diagnostic nasal endoscopy and functional endoscopic sinus surgery: an update and review of complications.

Diagnostic nasal endoscopy and functional endoscopic sinus surgery are relatively new techniques that have expanded our understanding of sinus physiology and the etiologies of sinus pathology. Diagnosis at an early stage of chronic sinus disease demonstrates that pathological changes are often limited to the osteomeatal complex and the anterior sinus group. Early disease refractory to aggressive medical management usually responds to surgical treatment. Surgery in this setting is most often performed under local anesthesia, without nasal packing, with an immediate improvement in the patient's symptoms, and with minimal risk of complications.

Prevalence of diabetic retinopathy and evaluation of risk factors. A review of 1,005 diabetic clinic patients.

One thousand and five diabetic patients were evaluated ophthalmologically and classified into one of four groups according to the retinopathy status of the worst of their eyes. The presence of various factors and their influence on retinopathy status were evaluated. Race, duration of diabetes, type of treatment, the presence of hypertension, a high serum cholesterol level, smoking and the presence of systemic complications of diabetes were found to have a statistically important influence on retinopathy status. Sex and type of diabetes had no such influence.

The organisation of an ophthalmological service for diabetics in a teaching hospital.

A new system of ophthalmological evaluation of diabetic patients in a teaching hospital has been devised. All the patients attending the diabetic clinic were screened by ophthalmologists. Any patient with a problem was then referred to a diabetic ophthalmology clinic where a full evaluation was done and treatment given where necessary. In an 18-month period 1,015 new ophthalmological diabetic patients were screened. Of these patients 13.6% had background retinopathy, 8.4% pre-proliferative retinopathy and 3.4% proliferative retinopathy, while 8.6% had maculopathy. These results show that even in a teaching hospital a significant percentage of patients already have pre-proliferative or even proliferative retinopathy when seen by an ophthalmologist for the first time. The importance of organising an ophthalmological service for the diabetic patient is stressed.

Middle ear semipermeable membrane tubes for prolonged retention.

Our 1981 prospective study confirmed the success of semipermeable membrane tubes in ventilation of middle ears, while protecting them from moisture when the patients bathed or swam. That study employed modern membrane tubes, with membrane-pore size 2.5 to 5 times greater than tubes used in early studies with less favorable outcomes. Currently, 21 patients with effusion had placement of a Donaldson design (Xomed, Inc., Jacksonville, Fla.) membrane tube in one ear and the new T-grommet membrane tube in the second ear. The T-grommet membrane tube is found to outlast the Donaldson design tube significantly. We recommend Donaldson membrane tubes for patients having tubes placed for the first time. For subsequent procedures, we employ T-grommet membrane tubes. We also use the T-grommet membrane tube for adults with chronic eustachian tube problems. Both tubes continue to show a low incidence of complications and draw highest praise from patients for their water-resistant capabilities.

Semipermeable membrane tubes: a prospective study.

Four years ago, we introduced the use of Castelli membrane tubes into our practice. Although initial reports in the literature and restrictions on indications from the manufacturer on use were extremely cautionary, we were able, by careful intraoperative technique and the use of postoperative antibiotics, to expand the use of the membrane tube and offer it to our entire patient population. To document this, we used a prospective study of 124 consecutive ears receiving a membrane tube. Follow-up study included clinical, audiometric, and tympanometric evaluation. We found the membrane tube to function extremely well in an extremely high percentage of ears, regardless of whether the ear contains serous or mucoid fluid. The advantages of membrane tubes include the lack of special care required, resultant high patient and parental acceptance, and the low incidence of draining ears with tubes in place.
