Infective juvenile steinernematid nematodes have been reported to enter their insect hosts through the mouth, anus, and spiracles (1-3,5-8). Information is lacking, however, for Steinernema scapterisci Nguyen & Smart, 1990 (4), a promising biological control agent of mole crickets in the genus Scapteriscus. This paper reports on the mode of entry of S. scapterisci into mole crickets and the pri...

Detailed morphological comparisons with light and scanning electron microscopy were made of white females and cysts of several isolates of Globodera tabacum sspp. tabacum (GTT), virginiae (GTV), and solanacearum (GTS). Observations focused on body shape, anterior region including head shape, lip pattern, stylet morphology, and the terminal area in females; and body shape and terminal area of cy...

Electron microscopy (EM) proved a very helpful means that solved a lot of information in different scientific aspects. EM is a very good tool in the hospitals and research centers. It was aimed to pile up available information on the biology in the descriptive morphology of nematodes and their immature stages by scanning (SEM) and transmission (TEM) electron microscopy. Watson (1965a, b) studie...

OBJECTIVE To present female pseudohermaphroditism in a prenatally diagnosed cloacal malformation. CASE REPORT A 29-year-old, primigravid woman referred for counseling at 17 weeks of gestation because of oligohydramnios and an intra-abdominal cyst in the fetus. The woman was not exposed to any virilizing agent during this pregnancy. She did not undergo any assisted reproductive technology for ...

Invasive candidiasis is an opportunistic infection that occurs in medical and surgical patients and carries a high mortality rate. Because its process always follows from colonization to amplification and to invasion, understand the colonization status is important to understand the likelihood of invasion. Screening for fungal colonization was performed with specimens from urine, throat, anus, ...

BACKGROUND Vaginal atresia is often associated with high imperforate anus. Because the commonly used methods of surgical vaginal creation (eg, McIndoe, intestinal segment interposition) may adversely affect urinary and fecal continence, the less-invasive Vecchietti procedure was selected for a young adult with a successfully corrected high imperforate anus. METHODS A 21-year-old was born with...

tion of the colon include surgical and interventional therapy options. With an acceptable risk level, palliative tumor resection is the treatment of choice depending on tumor location, tumor extension, and others. If surgical therapy is not a reasonable option, an alternative option would be the implantation of a stent. Unfortunately, the implantation of a stent through the anus can often be di...

This description is mainly based on experience gained at Great Ormond Street over the past nine years-about 300 cases having been admitted. It owes much to the teaching of Denis Browne. The classification of Ladd and Gross (I934) into four types has been abandoned because it did not seem to give useful grouping of cases with similar origins, treatment or prognosis. A classification has been dev...

The congenital H-type fistula between the anorectum and genital tract besides a normal anus is a rare entity in the spectrum of anorectal anomalies. We described a girl with an anovestibuler H-type fistula and left vulvar abscess. A 40-day-old girl presented symptoms after her parents noted the presence of stool at the vestibulum. On the physical examination, anus was in normal location and siz...

This report presents a surgical case of postoperative megarectum in an adult patient with imperforate anus/anorectal malformations. A 71-year-old Japanese male presented with a mass in the lower abdomen which was 15 × 12 × 8 cm in diameter, edema in the right lower extremity, and frequent urination. He had undergone sigmoid loop colostomy for an imperforate anus as a newborn infant. At 28 years...
