Testicular injury: late results of semen analyses after uniorchiectomy.

Semen parameters from 4 patients with testicular injury after uniorchiectomy were investigated. Semen volume and sperm morphology were not affected after the operation, but sperm count and motility were severely diminished. Two of 4 cases showed azoospermia, and the other 2 cases showed low values in both sperm count and motility. After 150-300 days from the operation, 2 cases recovered to the normal range in sperm count while the other 2 remained in the abnormal range. In sperm motility, 3 cases recovered to the normal range but the rest remained abnormal. The results suggest that long-term follow-up in semen parameters is needed when unilateral orchiectomy is performed.

Consultation system for diagnosis of headache and facial pain: RHINOS.

How does a doctor make a diagnosis based on his medical knowledge? A hypothesis is proposed concerning the diagnostic method of specialized doctors. The knowledge provided by an authority is used to establish a diagnostic system for headache and facial pain named RHINOS. RHINOS is based on the above hypothesis as represented by the programming language Prolog, which is operative on an NEC PC-9801 microcomputer with reasonable CPU time. This implementation form benefited greatly from RHINOS's portability and availability. RHINOS has four types of rules, two levels, acting as a forward link from manifestations to diseases. It also has disease images as a backward link from diseases to manifestations. With this knowledge, RHINOS makes not only a single diagnosis but also differential diagnosis, and diagnosis for complicated cases of two or more diseases. The disease-image link made this possible. RHINOS was applied for diagnoses of 50 patients: 82% of its answers were equivalent to those made by a specialist, and a further 16% were close to the right answers.
