On the basis of the studies of the embryogenesis of the vagina, the authors consider that malformations classically described as being partial aplasia should not be separated from the total absence of the vagina. The important feature is the association of a functioning or non functioning uterus with the absence of the vagina.
They believe that it is incorrect to describe the pouch of menstrual retention associated with a functioning uterus as “haematocolpos” and that is not justified to describe the cup-shaped vestibular depression as “hemi-vagina”.
According to the authors, although vaginal aplasia with a functioning uterus forming a pouch of menstrual retention constitutes an absolute indication for surgery, surgery is not justified in cases of vaginal aplasia with a non functioning uterus.
If Frank’s method fails in these cases, the patient or the couple should be referred to a sexologist, as women with this anomaly retain a perfect femininity, although unable to conceive. Incidental finding of cutaneous meningeal heterotopia in aplasia cutis congenita. Aplasia cutis congenita and cutaneous meningeal heterotopia are both rare congenital conditions that most commonly occur on the scalp and may appear clinically and histologically similar.
A subtype of aplasia cutis congenita, membranous aplasia cutis congenita, and cutaneous meningeal heterotopia are both proposed to result from neural tube closure errors. However, neither non-membranous nor membranous aplasia cutis congenita are known to occur together with cutaneous meningeal heterotopia in the same lesion. We report the incidental finding of cutaneous meningeal heterotopia within a lesion of aplasia cutis congenita.
Genetic Changes Nonsyndromic aplasia cutis congenita can have different causes, and often the cause is unknown. Because the condition is sometimes found in multiple members of a family, it is thought to have a genetic component; This gene belongs to a family of WNT genes that play critical roles in From labyrinthine aplasia to otocyst deformity.
Inner ear malformations IEMs are rare and it is unusual to encounter the rarest of them, namely labyrinthine aplasia LA and otocyst deformity.
They do, however, provide useful pointers as to the early embryonic development of the ear. LA is characterised as a complete absence of inner ear structures. While some common findings do emerge, a clear definition of the otocyst deformity does not exist. It is often confused with the common cavity first described by Edward Cock.
Our purpose was to radiologically characterise LA and otocyst deformity. Middle and inner ear findings were categorised by two neuroradiologists.
The bony carotid canal was found to be absent in all patients. Posterior located cystic structures were found in association with LA and otocyst deformity. In the most severe cases, only soft tissue was present at the medial border of the middle ear cavity. The individuals with otocyst deformity also had hypoplasia of the petrous apex bone.
These cases demonstrate gradual changes in the two most severe IEMs. Clarification of terms was necessary and, based on these findings, we propose defining otocyst deformity as a cystic structure in place of the inner ear, with the cochlea, IAC and carotid canal absent. This condition needs to be differentiated from the common cavity described by Edward Cook.
A clear definition of inner ear malformations is essential if outcomes following cochlear implantation are to be compared. Aplasia cutis congenita ACC is a skin condition of rare presentation, this disease is characterized by absence of skin at birth and associated with facial, skin and bone skull deformities.
The diagnosis is mainly clinical. Male 5 days after birth, unique product of primigravida mother and no family history of relevance. Physical examination revealed bilateral and symmetrical skin defects of both lower extremities, the disease is characterized by skin fragility, scabs, and coated pseudomembrane ulcers, decreased interdigital space between toes of the left foot, retraction of the foot and genu varum.
It was handled with allograft of epidermis cultured in vitro, general wound care and clinical follow-up. ACC associated with epidermolysis bullosa is one of the rarer forms of presentation. It is necessary to rule out other skin diseases.
Clinical management is recommended with biological or synthetic skin cover, infection prevention, early treatment of complications and clinical follow. Segmental aplasia of the uterine horn in a cat. Radiographs revealed 2 large blunt-ended tubular structures overlapping each other in the abdomen.
Segmental aplasia of the right uterine horn was diagnosed following exploratory laparotomy and ovariohysterectomy.
Vaginal aplasia occurs in 1 in 5, female live births. In this report, we evaluated a novel dual-force vaginoplasty technique aplxsia treatment of 11 patients with mdeular vaginal aplasia. The principle of the approach is to thin the atretic part between two counteracting forces. The instrument was inserted laparoscopically into the proximal hematocolpos.
Two balloon catheters, one for drainage and one for traction, were threaded over the inserter. The traction catheter was then threaded over a silicon tube, leaving the balloon in the meduoar portion of the vagina and connecting across the vaginal septum to a fenestrated Teflon olive, which was positioned against the distal surface of the vaginal septum. This created a dual “pushing and pulling” force across the septum, which, over days, pulls the upper vaginal pouch down while the vaginal dimple is pushed up.
Dmbarazo aplastic segment becomes thin and easy to dilate and permits achievement of vaginal patency. The drainage of the hematocolpos is predominantly through the balloon catheter so postoperative wound management is facilitated. Eleven menarchal girls were diagnosed with segmental vaginal aplasia. The dual-force vaginoplasty was performed on each and was tolerated well with no operative complications. They all reported establishment of the menstrual cycle and significant improvement of pain during follow-up.

Creation of a dual pushing-pulling force on the atretic vaginal segment is a feasible short procedure for management of segmental vaginal aplasia. Aplasia of the mandibular condyle associated with some orthopaedic abnormalities. A rare case of aplasia of mandibular condyle associated with some other orthopaedic problems is presented. A 5-year-old boy attended our clinic with a chief complaint of facial asymmetry and chewing difficulty. The mandible was deviated to the left. The occlusion also showed a deflection to the left of the mandibular midline.
He also had walking difficulty owing to a hip abnormality. Panoramic radiographic examination of the patient revealed that the left mandibular condyl was totally absent. The right condyle was unremarkable. His history revealed neither trauma nor any significant disease.
Aplasia is a rare anomaly and means the insufficient development of the mandibular condyle. True agnesis of the mandibular condyle is extremely rare. Association of the manifestations of the patient with some orthopaedic problems makes this case interesting.
Antibodies to recombinant human erythropoietin causing pure red cell aplasia. Recombinant human erythropoietin rHuEPO is used extensively in anemic patients on dialysis and other patients and is regarded as very safe and effective in the management of anemia in these patients. To date, there is no report on the development of antibodies to rHuEPO in the patients treated with this drug.
We report here a patient who developed antibodies to rHuEPO and as a result developed pure red cell aplasia. A year-old black male with end-stage renal disease secondary to hypertension was placed on chronic dialytic therapy and tolerated rHuEPO treatment well for two years. A rapidly progressive anemia was then noted which was unresponsive to maximal doses of rHuEPO and the patient soon became transfusion-dependent.
Bone marrow examination revealed paucity of red cell precursors. A detailed search for the cause of this pure red cell aplasia was unrevealing.
Serological tests for Parvovirus B19 infection were negative. Antibodies for rHuEPO were tested by radioimmuno-precipitation assay and were found positive.
In the course of several months, the antibody titer declined spontaneously to negligible levels with simultaneous improvement in the anemia and reappearance of red cell precursors in the bone marrow.
This is the first patient to be reported who formed antibodies to rHuEPO and as a consequence developed pure red cell aplasia. Thus we conclude that although very rare, antibody production to rHuEPO should be considered in evaluating patients with EPO-resistant anemia with no obvious etiology.

Congenital limb deformities in human neonates and Old World primate species embagazo been well characterized. The many probable causes of these congenital defects in skeletal structure include fetal exposure to environmental toxins and genetic influences.
In nonhuman primates, the cause frequently remains undetermined. In the case we present, the neonate presented for examination because of inability to cling to the dam. The forelimbs were contracted distally, and thumbs were absent. Radiographs indicated complete radial aplasia and other skeletal abnormalities. This description is the fi rst case study of congenital radial and thumb aplasia in a New World primate species. Reconstruction of bilateral tibial aplasia and split hand-foot syndrome in a father and daughter.
Tibial aplasia is of heterogeneous aetiology, the majority of reports are sporadic. We describe the reconstruction procedures in two subjects – a daughter and father manifested autosomal dominant AD inheritance of the bilateral tibial aplasia and split hand-foot syndrome.
Reconstruction of these patients required multiple surgical embarqzo and orthoprosthesis was apkasia. The main goal of treatment was to achieve walking. Stabilization of the ankle joint by fibular-talar-chondrodesis on both sides, followed by bilateral Brown-procedure at the knee joint level has been applied accordingly. Alpasia outcome was with improved function of the deformed limbs and walking was achieved with simultaneous designation of orthotic fitting.
A 9-month-old, female, domestic longhair cat with severe anaemia tested positive for feline medluar virus FeLV and was humanely destroyed and submitted for necropsy examination. Gross findings included a non-divided rostral telencephalon, consistent with semilobar holoprosencephaly. Histological examination of the bone marrow revealed an almost complete absence of erythroid precursor cells, consistent with pure red cell aplasiaand mild to moderate myelofibrosis.
This case demonstrates a very unusual central nervous system defect, as well as an atypical presentation of pure red cell aplasiain a FeLV-positive kitten. We report a patient with Hodgkin’s disease who developed PRCA due to parvovirus B19 after autologous SCT and who had an excellent response after treatment with gamma-globulin.
