PURPOSE: This study attempted to assess the treatment outcomes after microsurgical varicocelectomy in non-obstructive azoospermic patients and correlate the surgical outcomes with the histopathological patterns of their testes. MATERIALS AND METHODS: Fourteen non-obstructive azoospermic men who underwent testicular biopsy and varicocelectomy, between September 2001 and December 2002, were reviewed. Varicocelectomy was unilaterally and bilaterally performed in 12 and 2 patients, respectively, using an inguinal approach with a microsurgical technique. Postoperative semen analyses were performed in each patient four months after the varicocelectomy. RESULTS: In the testicular histology, hypospermatogenesis was identified in three, maturation arrest in five and Sertoli-cell-only syndrome in six of the subjects. After a mean follow-up of 7.4 months, motile sperm in the ejaculate was identified in 6(43%) of the non-obstructive azoospermic patients. These included 2 in hypospermatogenesis, 3 in maturation arrest and 1 in Sertoli-cell-only syndrome, in terms of their histopathology. These six had improvements in their sperm concentration and motility, which were 0.45x10(6)/ml and 51.3%, respectively. However, of these six, with motile sperm after varicocelectomy, 1 with maturation arrest and 1 with Sertoli-cell-only syndrome returned to their previous azoospermic state on their second postoperative semen analyses. A pregnancy was achieved by natural intercourse for 1 of the men(7.1%) with hypospermatogenesis. CONCLUSIONS: Microsurgical varicocelectomy offers non-obstructive azoospermic patients the chance to have sperm in their ejaculate, and therefore, the possibility of natural pregnancy. Microsurgical varicocelectomy may be considered with the initial treatment modality in selective non- obstructive azoospermic patients with varicocele prior to intervention with assisted reproductive technology.

PURPOSE: The ictal perfusion patterns of cerebellum and basal ganglia have not been systematically investigated in patients with temporal lobe epilepsy (TLE). Their ictal perfusion patterns were analyzed in relation with temporal lobe and frontal lobe hyperperfusion during TLE seizures using SPECT subtraction. MATERIALS AND METHODS: Thirty-three TLE patients had interictal and ictal SPECT, video-EEG monitoring, SPGR MRI, and SPECT subtraction with MRI co-registration. RESULTS: The vermian cerebellar hyperperfusion (CH) was observed in 26 patients (78.8%) and hemispheric CH in 25 (75.8%). Compared to the side of epileptogenic temporal lobe, there were seven ipsilateral hemispheric CH (28.0%), fifteen contralateral hemispheric CH (60.0%) and three bilateral hemispheric CH (12.0%). CH was more frequently observed in patients with additional frontal hyperperfusion (14/15, 93.3%) than in patients without frontal hyperperfusion (11/18, 61.1%). The basal ganglia hyperperfusion (BGH) was seen in 11 of the 15 patients with frontotemporal hyperperfusion (73.3%) and 11 of the 18 with temporal hyperperfusion only (61.1%). In 17 patients with unilateral BGH, contralateral CH to the BGH was observed in 14 (82.5%) and ipsilateral CH to BGH in 2 (11.8%) and bilateral CH in 1 (5.9%). CONCLUSION: The cerebellar hyperperfusion and basal ganglia hyperperfusion during seizures of TLE can be contralateral, ipsilateral or bilateral to the seizure focus. The presence of additional frontal or basal ganglia hyperperfusion was more frequently associated with contralateral hemispheric CH to their sides. However, temporal lobe hyperperfusion appears to be related with both ipsilateral and contralateral hemispheric CH.

7.Isolated Dorsal Ulnar Cutaneous Nerve Injury Occurring During Activities of Daily Living.

Journal of the Korean Neurological Association 2017;35(2):80-84
The dorsal ulnar cutaneous nerve (DUCN) is the sensory branch of ulnar nerve supplying sensation to the dorsal ulnar aspect of the hand. Isolated DUCN injury is known rare. We report 3 cases of isolated DUCN injury caused by stretch injury and mild blunt injury during activities of daily living. Isolated DUCN injury may more frequently occur than we thought. Nerve conduction study and ultrasonography are useful method to localize the lesion and to evaluate the structural etiology.

Acardiac twinning affects 1 in 100 monozygotic twin pregnancies and 1 in 35,000 pregnancies overall. This condition is characterized by the absence or rudimentary development of fetal heart, and associated with various anomaly. The presence of an acardiac twin requires the normal (or "pump") twin to provide circulation for itself, as well as the acardiac sibling. The acardiac malformations are uniformly fatal in the affected twin, and mortality in the co-twin is as high as 55%. The principal perinatal problems associated with acardiac twinning are pump-twin congestive heart failure, maternal hydramnios, and preterm delivery. We recently experienced a case of acardius anceps associated with a normal male infant, so present with a brief review of the literature.

The reservoir hosts of Thelazia callipaeda were examined. The eyes of the 76 dogs raised at farm, 78 military dogs (shepherds), 96 cattle, and 105 pigs were investigated for the presence of eyeworm. Among them, six worms of T. callipaeda were collected from two dogs raised at farm (2.7%), and 188 worms from 26 shepherds (33.5%). No worms were recovered from the cattle or pigs. These results suggest that the dogs, especially the military dogs are serving as a reservoir host of T. callipaeda. in Korea.
