Maternal glucose loading and fetal cardiac function in humans.

Fetal cardiac function determined using M-mode echocardiography was studied subsequent to the maternal intravenous injection of 20 g of glucose. There were 11 appropriate for date infants (AFD), 7 noneventful, light for date infants (LFD) and one high risk fetus in severe toxemia of pregnancy (Case 1), at 32-40 weeks' gestation. The fetal heart rate showed no significant changes after glucose injection in each group. The left ventricular fractional shortening and cardiac output showed significant changes, whereas the right ventricular fractional shortening and cardiac output were unchanged in both AFD and LFD. In Case 1, the adverse change was noted in both left and right cardiac functions, as compared with AFD or LFD. The combined total cardiac output in AFD increased significantly at 5 min following glucose injection, whereas that in LFD did not change significantly. On the other hand, the combined total cardiac output in Case 1 decreased markedly at 5 min after glucose injection. These findings show that the glucose loading in the mother alters cardiac function in the fetus.     

Transvaginal color Doppler imaging for hemodynamic assessment of reproductive tract tumors.

Transvaginal color Doppler flow imaging was carried out on 68 Japanese women (normal, 10; uterine myoma, 21; cervical carcinoma, 7; endometrial carcinoma, 10; benign ovarian tumor, 12; ovarian carcinoma, 8). Blood flow velocity waveforms were evaluated by calculation of the resistance index (RI). In 6 patients with cervical carcinoma neovascularization was evident within the cervix. In all patients with endometrial carcinoma such signs were present adjacent to and/or within the endometrium. These findings were absent in normal women and in those with myomata. There was a significant difference between the RI (0.510 +/- 0.097) in patients with cervical carcinoma and in normal women (0.881 +/- 0.048) in the ascending branch. In endometrial carcinoma the RI (0.535 +/- 0.158) was significantly lower in the arcuate artery compared to the normal uterus (0.768 +/- 0.075) and patients with uterine myoma (0.679 +/- 0.131), respectively. There was no area of neovascularization in the normal ovaries. Neovascularization was confirmed in four patients with a benign ovarian tumor and in all patients with an ovarian carcinoma. A significantly lower RI was obtained in cases of ovarian carcinoma (0.503 +/- 0.122) than in patients with benign ovarian tumors (0.888 +/- 0.216). Transvaginal color Doppler imaging and pulsed Doppler analysis may be useful diagnostic tools to differentiate benign and malignant tumors.     

Wound,pressure ulcer and burn guidelines – 1: Guidelines for wounds in general,second edition

The Japanese Dermatological Association prepared the clinical guidelines for the “Wound, pressure ulcer and burn guidelines”, second edition, focusing on treatments. Among them, “Guidelines for wounds in general” is intended to provide the knowledge necessary to heal wounds, without focusing on particular disorders. It informs the basic principles of wound treatment, before explanations are provided in individual chapters of the guidelines. We updated all sections by collecting references published since the publication of the first edition. In particular, we included new wound dressings and topical medications. Additionally, we added “Question 6: How should wound-related pain be considered, and what should be done to control it?” as a new section addressing wound pain, which was not included in the first edition.     

Fulminant strongyloidiasis successfully treated by subcutaneous ivermectin: an autopsy case]

We report a 49-year-old man who was a human T-cell leukemia virus type 1 (HTLV-1) carrier, born in Okinawa prefecture where both strongyloidiasis and HTLV-1 are endemic. He presented with fever, headache and urinary retention. On the basis of CSF examination and MRI findings, his condition was diagnosed as myelitis. He received methylprednisolone pulse therapy. He was transferred to our hospital due to severe paralytic ileus. Strongyloides stercoralis (S. stercoralis) was found in the duodenal stained tissue of a biopsy specimen. Ivermectin applied both orally and through enema were ineffective because of severe ileus and intestinal bleeding. Nine mg (200 microg/kg) of ivermectin solution was administered subcutaneously every other day for five days (total amount 45 mg). The S. stercoralis burden in the stool decreased and paralytic ileus gradually resolved. Three weeks after the resolution of S. stercoralis infection, purulent meningitis developed and acute obstructive hydrocephalus appeared. The hydrocephalus improved by ventricular drainage. Approximately three months after drainage, he died of incidental aspiratory pneumonia. Autopsy showed neither eggs nor larvae of S. stercoralis in the organs. In this case, the fourth reported case in the world, subcutaneous ivermectin injection was dramatically effective. We should consider a diagnosis of strongyloidiasis for any patient from Okinawa prefecture who was an HTLV-1 carrier presenting with unknown origin ileus after treatment of steroid therapy.
