True hermaphroditism: 10 years' experience

Abstract True hermaphroditism (TH) is the rarest variant of intersex malformations. By definition, these patients have both ovarian and testicular tissue. Most present due to ambiguous genitalia and/or gynecomastia. From 1986 to 1996, we treated 97 patients with intersex disorders; there were 4 with TH. In all cases testicular and ovarian tissue was separate. In 3 patients the external genitalia were ambiguous and 1 had hypoplastic male genitalia. Three patients had a 46, XY and 1 a 46, XX karyotype. Three patients had been listed as males and 1 as a female. The number of operations required varied from 3 to 9 (mean 5.7 per patient). Two patients who had been raised as males finished puberty with hypogenitalism and hypoplastic testes. One married and could have erections, but no ejaculation. Two male patients have been on supplementary androgen therapy. The only patient who had been raised as a female after clitorovaginoplasty had a 6-cm-deep, blind-ending vagina that was deepened to 12 cm with bougienage, so that she was capable of having normal intercourse. It is felt at present that most patients with TH should be raised as females. This was confirmed in our patients as well, which underlines the significance of early diagnosis.

Surgical treatment of cloacal anomalies

Abstract From 1989–1998 14 patients were treated with cloacal anomalies: 5 typical cloacas (PC), 5 posterior cloacas, and 4 cloacal exstrophies (CE); 12 underwent surgery. Four typical cloacas were resolved with posterior sagittal anorectovagino-urethroplasty (PSARVUP), whereas in the 5th total urogenital mobilization (TUM) was used. Three PCs were managed with transanorectal TUM and 2 with anterior TUM without opening the anal canal and rectum (without a protective colostomy). Two CEs were treated with atypical procedures. Two patients with CE died without surgery and 2 died after surgery due to complex associated anomalies. During postoperative follow-up of 1–8 years, 5 children had voluntary bowel movements and no soiling while the others had soiling with or without enemas; 1 had stress incontinence; 3 were on clean intermittent catheterization due to neurogenic bladder and were dry.PSARVUP provides a satisfactory result if there is no sacral anomaly. TUM makes this operation easier to perform. In patients with a PC it is sometimes possible using TUM to separate the urinary from the genital tract and remove the accessory urethra without opening the anus and rectum.

Ruptured intramural intestinal hematoma in an adolescent patient with severe hemophilia A

We report on a 17-year-old patient with severe hemophilia A without inhibitors who developed abdominal bleeding after an episode of severe cough. Abdominal ultrasound showed intramural intestinal hematoma as well as large amount of peritoneal fluid appearing as blood and right hematocele. Abdominal CT revealed markedly thickened intestinal wall in sigmoidal region. Patient was managed with replacement therapy as well as peritoneal drainage with favorable outcome. This is the first report on a hematoperitoneum in a hemophiliac due to ruptured intramural sigmoidal hematoma.

MYELOID SARCOMA PRESENTING WITH BILATERAL PROPTOSIS AND KIDNEY INFILTRATION

The authors describe a male infant with a history of transient pancytopenia who developed progressive bilateral proptosis associated with diffuse infiltration of the kidney and normal bone marrow. The histopathological examination of the kidney revealed diffuse infiltration of cells of myeloid origin with monocytic differentiation. Although orbital involvement by myeloid sarcoma, with or without concurrent acute myeloid leukemia, is well known, there are distinctive features in this patient that are not reported in the literature, namely bilateral proptosis and simultaneous presence of bilateral kidney infiltration, which enabled diagnosis.

Pseudoachondroplasia: A case report

INTRODUCTION Pseudoachondroplasia (PSACH) is an autosomal dominant osteochondrodysplasia due to mutations in the gene encoding cartilage oligomeric matrix protein. It is characterized by rhizomelic dwarfism, limb and vertebral deformity, joint laxity and early onset osteoarthrosis. We present the girl with the early expressed and severe PSACH born to clinically and radiographically unaffected parents. CASE OUTLINE A 6.5-year-old girl presented with short-limbed dwarfism (body height 79.5 cm, < P5;-32%) and normal craniofacial appearance and intelligence. The girl was normal until 3 months of age when she expressed growth retardation with apparently shorter extremities in relation to the torso. With age, her rhizomelic dwarfism became increasingly visible, and since completed 15 months of age, when she started to walk, the disease was complicated with genu varum, lumbar lordosis and abnormal gait. Beside visibly short forearms, short, broad and ulnar deviation of the hands, brachydactyly and joint hyperlaxity, the radiographic picture showed markedly flared metaphyses, small and irregular epiphyses and poorly formed acetabulum. CONCLUSION PSACH is an achondroplasia-like rhizomelic dwarfism recognized by the absence of abnormality at birth, normal craniofacial appearance, characteristic epiphyseal and metaphyseal radiographic finding and joint hyperlaxity.

Effectiveness of Wharton’s jelly stem cells in gastroschisis repair using the inner surface of the umbilical cord as a patch: long-term results

ObjectiveThis retrospective study was designed to assess and compare the anatomical, functional, and esthetic appearance of the umbilical area in patients after repair of gastroschisis using the inner surface of the umbilical cord (UC) and in patients with omphalocele conservatively treated. BackgroundOur procedure transformed gastroschisis into an ‘artificial–surgical omphalocele’ in which the prolapsed intestine was covered with an umbilical patch, the inner surface of which contained Wharton’s jelly (WJ). MethodsWe have summarized an experience of 17 years in repairing gastroschisis using the inner surface of the UC. From 1986 to 2003, 21 infants with gastroschisis and one with a ruptured omphalocele were treated with this technique. We used Eagle’s medium to prove the validity of the umbilical stump and the duration of its viability. The inner surface of the umbilical patch is a ‘live’ structure with WJ, which contains mucoid connective tissue and fibroblast-like cells – that is, stem cells producing cutis, adipose, and connective tissue. ResultsUsing our method, early control assessment of 18 of 21 patients with gastroschisis, at intervals of 1–3 months, showed good functional and esthetic results. Clinical long-term results in terms of anatomical, clinical, and functional findings were excellent. Besides clinical testimony, we used high-frequency ultrasonography to make an appraisal of the effectiveness of WJ stem cells in the repair of gastroschisis, and compared our results with healthy volunteers and patients with omphalocele conservatively treated. ConclusionThis paper describes the effect of the local application of WJ – that is, mesenchymal stromal cells derived from the inner surface of the umbilical stump – and its influence on the healing process of the birth defect and wound.
