Multiple recurrent abscesses in a patient with undiagnosed IL-12 deficiency and infection by Burkholderia gladioli.

We report the occurrence of two severe illnesses experienced by one patient over a 19 year period of time. Both illnesses were characterized by severe inflammation and tissue destruction. Signs and symptoms of the first illness were characteristic of lymphogranuloma venereum (LGV). The second illness mimicked scrofula. During the second illness the patient was discovered to have a rare immunodeficiency due to auto-antibodies to Interleukin (IL)-12 and infection by Burkholderia gladioli, a plant pathogen usually harmless in humans. We were able to retrieve biopsies from the first illness to establish that B. gladioli was already present during the original presentation. That first illness lasted 5 year s, but she survived without the correct pathogen ever being identified, and without a diagnosis of immunodeficiency. After a remission of 10 year s, she experienced her second illness. The responses to treatment before and after the correct diagnoses were established provide us with an excellent opportunity to consider and discuss how disease expression reflects complex relationships between host defenses and microbial characteristics.

A Report of Two Cases of Age-Related Changes in Cervical Morphology in Postmenopausal Women with Vaginal Adenosis.

This paper presents two cases of women who had extensive vaginal adenosis from prenatal DES exposure, extending almost halfway down the vaginal canal. Both women were followed for decades with annual exams and Pap smears until after menopause. Clinical examination in both cases initially showed an absent pars vaginalis of the cervix, vaginal adenosis, and shallowness of the fornices. Several decades of annual exams showed these stigmata of DES exposure gradually disappear as the upper vagina progressively contracted. After menopause the upper vagina in both cases transformed into what appeared to be a normal cervix with all adenosis involuted into a normal endocervical canal. A timeline was created to show the morphological changes that were observed over time. This timeline illustrates how severe vaginal stenosis above the level of the squamocolumnar junction developed in middle age and was followed in the postmenopause by fusion of the upper vaginal walls in the midline resulting in the appearance of a normal, but prolapsed, cervix.

Intracellular Organisms as Placental Invaders.

In this article we present a novel model for how the human placenta might get infected via the hematogenous route. We present a list of diverse placental pathogens, like Listeria monocytogenes or Cytomegalovirus, which are familiar to most obstetricians, but others, like Salmonella typhi, have only been reported in case studies or small case series. Remarkably, all of these organisms on this list are either obligate or facultative intracellular organisms. These pathogens are able to enter and survive inside host immune cells for at least a portion of their life cycle. We suggest that many blood-borne pathogens might arrive at the placenta via transportation inside of maternal leukocytes that enter the decidua in early pregnancy. We discuss mechanisms by which extravillous trophoblasts could get infected in the decidua and spread infection to other layers in the placenta. We hope to raise awareness among OB/GYN clinicians that organisms not typically associated with the TORCH list might cause placental infections and pregnancy complications.

First trimester typhoid Fever with vertical transmission of salmonella typhi, an intracellular organism.

We report a case in which placental abruption occurred at 16 weeks following first trimester diagnosis and treatment for typhoid fever. Unexpectedly Salmonella enterica serovar Typhi (S. Typhi) was found in fetal tissues at autopsy. Using information from the murine model of typhoid fever in pregnancy, we draw parallels between S. Typhi and L. monocytogenes to develop a plausible hypothesis to explain how this organism was able to cross the placenta in the first trimester to cause abruption, inflammation, and expulsion of the fetus and placenta. We hope that this model for understanding placental infections by the hematogenous route helps to raise awareness that organisms not typically associated with TORCH infection can nevertheless cause placental infection and pregnancy loss.

Nonclassic 21-hydroxylase deficiency presenting as endometrial hyperplasia with uterine bleeding in a 67-year-old woman.

OBJECTIVE: To report for the first time a case of postmenopausal endometrial hyperplasia caused by nonclassic 21-hydroxylase deficiency (NC21OHD). The specific combination of mutations associated with this case has never before been reported. DESIGN: Case report. SETTING: Private academic practice. PATIENT(S): A 67-year-old woman with uterine bleeding due to endometrial hyperplasia was found to have premenopausal gonadotropins with elevated estrogens. Endocrine workup revealed increased 17-hydroxyprogesterone (17-OHP), which led to molecular testing to establish a diagnosis of NC21OHD. INTERVENTION(S): Trial of suppression with low-dose oral dexamethasone. MAIN OUTCOME MEASURE(S): Resolution of postmenopausal bleeding. RESULT(S): Total estrogens normalized with treatment, and the endometrial stripe became normal. CONCLUSION(S): This is an unusual case of NC21OHD in which the sole presentation was persistent endometrial hyperplasia, with bleeding past the normal age for menopause. In women with unusual endometrial hyperplasias of this type, we suggest endocrine testing before proceeding to hysterectomy.

Luckenschadel skull: a forgotten entity.

BACKGROUND: Luckenschadel skull is an ossification disorder in which the fetal skull appears fenestrated. It is almost always associated with Chiari II malformation and meningomyelocele. CASE: We report a case of fatal subgaleal hemorrhage occurring in a full-term infant with undiagnosed Chiari II malformation, meningomyelocele, and luckenschadel skull. A cesarean delivery was performed after attempted vacuum and forceps delivery for fetal distress. CONCLUSION: Obstetricians should be aware that fetuses with antenatal diagnosis of neural tube defects could have luckenschadel skull. Questions are raised concerning the possible clinical significance of this anomaly, especially in the context of a vacuum delivery.
