Safe vaginal delivery in a renal transplant recipient: A case report.

Here, we aimed to present a case of safe vaginal delivery in a renal transplant recipient and to mention the possible additional risks of caesarean section in such cases. A 40 year-old patient (G4P3), who had undergone renal transplantation 5 years ago, was admitted to our clinic at 39(2/7) weeks of pregnancy. The transplanted kidney at right iliac fossa was sonographically normal except for grade 1 hydronephrosis; the proximity of vascular anastomoses between the transplanted kidney and iliac vessels to the lower segment of the uterus was remarkable. There was no contraindication for vaginal delivery and it was believed that there would be a possible risk of injury to the transplanted kidney with caesarean delivery. The patient delivered a healthy baby weighing 3540 grams. There is a risk of injury to the renovascular and ureter anastomoses in renal transplant recipients during caesarean delivery. Normal vaginal delivery without abdominal compression is the safest method of delivery in these patients. If a situation that can necessitate internal iliac artery ligation or caesarean hysterectomy such as placenta accreata is expected, surgery should be performed in a centre where the renal transplant surgeon can oversee the surgery.

Intraperitoneal Nigella sativa for prevention of postoperative intra-abdominal adhesions in rats.

OBJECTIVE: To evaluate intraperitoneal administration of Nigella sativa (NS) to prevent postoperative intraperitoneal adhesion (PPA) after surgical manipulation of rat uterine horn. MATERIALS AND METHODS: Two forms of NS were used in the study (Volatile oil (NSVO) and the ethanolic extract (NSEE)). A total of 50 rats were randomly assigned to the sham group (n = 10), control group (n = 10), NSVO group (n = 10), NSEE group (n = 10), and the Seprafilm group(n = 10). After 14 days, rats were sacrificed. Adhesions were examined macroscopically, and degree of adhesions was scored. A part of horn was excised, and superoxide dismutase (SOD) and glutathione peroxidase activities as well as malondialdehyde levels were evaluated, and histological score was calculated. RESULTS: Total microscopic score of the NSEE group was significantly lower than the control group (p = .001) and was marginally significantly lower than the seprafilm group (p = .005). Collagen formation score was higher in the seprafilm group compared to the sham and NSEE groups (p < 0.001, p = .003, respectively). Apoptotic cells were lower in the NSEE group compared to the control group (p = .003) and also lower in the NSEE and NSVO groups compared to the seprafilm group (p = .001, p < .001, respectively). Only SOD activity was higher in the NSVO and seprafilm groups compared to the control group (p < .001). CONCLUSION: NSEE form seems to have a possible effect in the prevention of PPAs. This may occur by its effect in decreasing collagen formation and by decreasing apoptosis in the injured tissues. NSVO form seems to induce SOD. Therefore, combined use of NSVO with seprafilm may increase the adhesion preventive effect of seprafilm.

Enterobius vermicularis: Can it be a possible pathogen in Bartholin gland abscess formation?

The most frequent disorders of the Bartholin glands are cysts or abscesses. Bartholin gland abscesses occur generally as a result of polymicrobial infections or agents that cause sexually transmitted diseases. But as far as we know, no parasite has been previously reported among the infectious agents that are detected from the abscesses of the Bartholin gland. Here, we report a 45-year-old woman, in the Bartholin abscess aspirate of whom Enterobius vermicularis eggs were detected in between the inflammatory infiltrate by cytological examination.

Intravascular papillary endothelial hyperplasia: histomorphological and immunohistochemical features.

BACKGROUND: Intravascular papillary endothelial hyperplasia (IPEH) is a benign intravascular process with features mimicking other benign and malignant vascular proliferations. IPEH lesions predominate in the head-neck region and the extremities. The characteristic histomorphological feature of IPEH is a papillary structure covered with hyperplastic endothelial cells within the vascular lumen. It is critical that this clinically benign lesion should not be mistaken for well-differentiated vascular tumors. In addition to the characteristic histological features, other useful diagnostic features included the intra-luminal location of the lesion, an intimate association with the organizing thrombus, the absence of necrosis, cellular pleomorphism, and mitotic activity. In addition, immunohistochemistry may indicate the vascular origin and proliferative index. In this study, we evaluated histomorphological and immunohistochemical findings (CD31, CD34, FVIII, type IV collagen, SMA, MSA, CD105, and Ki-67 staining) of ten IPEH cases. METHODS: Ten IPEH cases were re-examined for a panel of histomorphological and immunohistochemical features. CD31, CD34, FVIII, Type IV collagen, SMA and MSA antibodies utilized for immunohistochemical analysis.The histomorphological and immunohistochemical findings were evaluated by two independent pathologists using light microscopy. RESULTS: All ten cases involved intraluminal lesions with characteristic features of IPEH. All ten cases (100%) were stained positive for CD31 and CD34. The degree of staining with FVIII, type IV collagen, SMA, and MSA was variable. CONCLUSION: In this series of specimens, CD31 and CD34 were the most sensitive markers indicating the vascular origin of the lesion. Staining for the other vascular markers (FVIII, type IV collagen, SMA and MSA) was variable. Different maturation degrees of lesions may account for the variation in immunohistochemical staining. Few previous investigations evaluated a wide range of antigen panels in IPEH sections. In our opinion, the evaluation of immune markers in a larger sample set will reveal new features in the maturity and developmental pathogenesis of vascular lesions and angiogenesis. IPEH is a benign lesion, which must be differentiated from malignant tumors such as angiosarcoma and Kaposi's sarcoma. Improved definition of IPEH lesions using immunohistochemical markers may enhance the ability to differentiate between various vascular lesions.

Development of six tumors in a sebaceus nevus of jadassohn: report of a case.

Nevus sebaceus of Jadassohn is a congenital cutaneous hamartoma comprised of multiple skin structures. It has the potential to develop into variety of neoplasms of various epidermal adnexal origins. While multiple tumors may occasionally arise, it is unusual for more than four tumors to arise simultaneously within a single sebaceus nevus. Here in, we report a case of a 70-year-old woman with six neoplastic proliferations including a syringocystadenoma papilliferum, pigmented trichoblastoma, tubular apocrine adenoma, sebaceoma, tumors of follicular infundibulum and superficial epithelioma with sebaceus differentiation arising in a long standing nevus sebaceus on the scalp. Our case is extraordinary because a single nevus sebaceus contained six neoplastic proliferations with differentiation toward the folliculosebaceous-apocrine unit.

Use of progestogens in pregnant and infertile patients.

Progesterone is an essential hormone in the occurence and maintenance of pregnancy. Natural or synthetic progestogens are commonly used in pregnant patients or patients undergoing infertility treatments for various indications. Most frequently put indications for the use of progestogens in these patient populations are the prevention of spontaneous preterm birth, the prevention of pregnancy loss in pregnancies with an unexplained recurrent pregnancy loss and in patients with threatened abortion. It is also used in pregnant women undergoing nonobstetric surgery, for infertility or recurrent pregnancy loss that is thought to be due to luteal phase defect or as a luteal support in stimulated IVF cycles. We aimed to review the current evidence for the use of progestogens in each of these settings.

Hyberbaric oxygen increases atresia in normal & steroid induced PCO rat ovaries.

BACKGROUND: In this study, we investigated the effect of hyperbaric oxygen therapy (HBOT) on the morphology of estradiol valerate (EV) induced polycystic ovary (PCO) to find a new treatment modality for improvement of PCO. METHODS: The rats were divided into four groups. Group1, control; group 2, PCO group; group 3, PCO with HBOT group and group 4, normal ovary with HBOT. PCO was induced by a single intramuscular injection of 4 mg EV in adult cycling rats. Other rats with normal ovaries had oil injection as placebo. HBOT was applied to third and fourth groups for six weeks. Histopathologic evaluation of ovaries of all groups were performed & compared. RESULTS: Six weeks of HBOT was resulted in increase in follicular atresia, decrease in the number of primary, secondary, tertiary follicles and decrease in the number of fresh corpus luteum in normal rat ovary. HBOT on polycystic rat ovary, resulted in significant increase in atretic follicles which were already present. CONCLUSIONS: HBOT of six weeks itself, changed ovarian morphology in favor of atresia both in PCO group and control group. This result of aggravated follicular atresia after HBOT on EV induced PCO may be due to long-term exposure in our protocol which with this state seems to be inapplicable in the improvement of PCO morphology.

A different type of branchial fistula as part of a branchiootorenal syndrome.

We describe an extremely rare case of a complete fistula, a combination of the first 2 branchial arches as a component of branchiootorenal syndrome. A 13-year-old girl presented with the complaint of intermittent drainage from bilateral preauricular and right lower neck external openings. A contrast fistulogram revealed a complete fistula. Diagnostic features and surgical techniques are discussed in detail.

Intraperitoneal administration of single dose type I collagen or low dose melatonin to prevent intraperitoneal adhesion formation: a comparative study.

OBJECTIVE: To compare the prevention of adhesion formation by type I collagen or melatonin solutions in the rat model. STUDY DESIGN: A total of 40 female Wistar albino rats were randomly assigned to four groups-type I collagen, melatonin, vehicle control and sham groups. Following midline laparotomy, a standard injury was made on the right uterine horn using bipolar cautery. The animals in the sham group underwent midline laparatomy only. One milliliter of type I collagen, melatonin or vehicle control was instilled onto the injured area immediately before abdominal closure. Fourteen days after the surgery, the type and extent of adhesion formation as well as the uterine horn tissue superoxide dismutase (SOD) and catalase (CAT) activity, and malondialdehyde (MDA) levels were measured. RESULTS: Both the type and extent of adhesion formation were significantly lower in the type I collagen and melatonin groups compared to the control group. The tissue SOD and CAT activity was significantly higher, and MDA levels were significantly lower in the type I collagen and melatonin groups compared to the control group. CONCLUSION: Intraperitoneal administration of type I collagen or low dose melatonin solution onto the injured areas may be an attractive adjuvant to reduce postoperative adhesion formation.

An endometriotic vault fistula presenting with monthly bleeding after hysterectomy.

INTRODUCTION: The aetiology of endometriosis remains unknown. The clinical presentation of endometriosis can be highly variable, occurring in numerous potential locations outside the abdomen and associated with distinct complaints. Recurrence is common, though we present a very rare case of recurrence and complication. CASE PRESENTATION: A 42-year-old caucasian woman was admitted to our unite with monthly vaginal bleeding lasting 3-5 days, beginning from 6 months after previous hysterectomy and right salpingo-oophorectomy surgery for myoma and endometrioma. We suspected of endometrioma of the left ovarium upon transvaginal ultrasonography, and diagnosed vault fistula from the endometriosis cyst to the vagina. We re-operated the patient using Pfannenstiel incision, and performed left-oophorectomy and fistula repairment. The Pouch of Douglas was obliterated and many bowel adhesions were present, indicating a stage IV endometriosis. According to our assessment, stage IV endometriosis had been present in the previous surgery. CONCLUSIONS: Considering that the short-term endometriosis recurrence is higher in premenopausal age and in advanced stage of endometriosis, bilateral oophorectomy together with hysterectomy may be a better operational choice for these patients.
