Pancreatic steatosis is an independent risk factor for post-transplant diabetes mellitus in kidney transplant patients.

BACKGROUND AND AIM: Post-transplant diabetes mellitus (PTDM) is associated with an increased risk of post-transplant cardiovascular diseases, and several risk factors of PTDM have been shown in the literature. Yet, the relationship between hepatic and pancreatic steatosis with post-transplant diabetes mellitus remains vague. We aimed to evaluate pancreatic steatosis, a novel component of metabolic syndrome, and hepatic steatosis association with post-transplant diabetes mellitus in a single-center retrospective cohort study conducted on kidney transplant recipients. METHOD: We have performed a single-center retrospective cohort study involving all kidney transplant recipients. We have utilized pretransplant Fibrosis-4, nonalcoholic fatty liver disease fibrosis score, and abdominal computed tomography for the assessment of visceral steatosis status. RESULTS: We have included 373 kidney transplant recipients with a mean follow-up period of 32 months in our final analysis. Post-transplant diabetes mellitus risk is associated with older age (p < .001), higher body-mass index (p < .001), nonalcoholic fatty liver disease-fibrosis score (p = .002), hepatic (p < .001) or pancreatic (p < .001) steatosis on imaging and higher pre-transplant serum triglyceride (p = .003) and glucose levels (p = .001) after multivariate analysis. CONCLUSION: Our study illustrates that recipients' pancreatic steatosis is an independent predictive factor for post-transplant diabetes mellitus including in kidney transplant patients.

Immune checkpoints inhibitors and its link to acute kidney injury and renal prognosis.

BACKGROUND: Immunotherapy with immune checkpoint inhibitors (ICPi) may cause acute kidney injury (AKI) and their use is increasing. MATERIALS AND METHODS: This is a single-center retrospective cohort study of patients receiving ICPi drugs for solid organ malignancies. ICPi-related AKI, the need for renal replacement therapy during or following ICPi treatment, and the associated mortality was studied. RESULTS: Two hundred thirty five patients were included in the final analysis. Patients with (N = 40) and without (n = 195) AKI had similar age, sex, type of ICPi, baseline serum creatinine levels, comorbidities and mortality; while patients with AKI were more likely to be receiving a nephrotoxic agent or be treated for genitourinary malignancy. 18 patients had ICPi-related AKI; 7 of these patients underwent kidney biopsy, which showed acute interstitial nephritis while the remaining 11 were diagnosed on clinical parameters. 18 (45%) patients recovered kidney function after AKI. No differences were observed between patients with and without kidney function recovery, although patients without recovery had a numerical, but not statistically significant, higher mortality. Patients with biopsy-confirmed ICPi-induced AKI had an increased risk of mortality, as compared with the rest of the population-HR 1.83, 95% CI 1.22-2.74, p = 0.003. CONCLUSION: Use of nephrotoxic drugs and the location of malignancy appear to be common drivers of AKI in patients receiving ICPis for solid organ malignancy. Whether nephrotoxic agents or urinary tract obstruction may favor ICPi-related autoimmunity should be further studied.

Histopathological and Immunohistochemical Study of the Effect of Sildenafil Citrate, Vitamin A, Vitamin C and Vitamin E on Wound Healing in Alloxan-induced Diabetic Rats

ABSTRACT Objective: To examine the impact of sildenafil citrate, vitamin A (Vit A), vitamin C (Vit C) and vitamin E (Vit E) on wound healing in a rat model of diabetes (n = 100). Methods: Diabetes was induced in the rats by intraperitoneal (i.p.) administration of alloxan. After anaesthesia, a standard wound was created on the back of each rat using a 10-mm sterile punch. The rats were randomly divided into 10 groups (n = 10 in each), as follows: normal saline, glibenclamide, insulin, sildenafil, Vit A, Vit C, Vit E, Vit A + sildenafil, Vit C + sildenafil, Vit E + sildenafil daily for 15 days. The rats were sacrificed after being anaesthetized 3, 7 and 15 days later. Wounded skin tissue samples were collected for histopathological and immunohistochemical analyses. Results: On the 7th day, epithelial regeneration was completed in groups 8 and 9. Angiogenesis was insufficient in group 2. In terms of connective tissue proliferation, partially matured connective tissue was observed in group 4. On the 15th day of the study, groups 8, 9 and 10 had mature connective tissue. However, group 1 still had exudate-containing neutrophils. Immunohistochemically, on the 3rd day, the level of inducible nitric oxide synthase (iNOS) reactivity was intense in macrophages and neutrophils surrounding the wound edges in groups 4, 8, 9 and 10. The level of iNOS reactivity was moderate in group 6 and less distinct in groups 1, 2, 3, 5 and 7. Conclusion: Sildenafil citrate, together with Vit A and Vit C, is beneficial in wound healing of diabetic rats.

Intravenous metoclopramide versus dexketoprofen trometamol versus metoclopramide+ dexketoprofen trometamol in acute migraine attack in the emergency department: A randomized double-blind controlled trial.

STUDY OBJECTIVE: The objective of this study was to determine the analgesic efficacy and safety of intravenous, single-dose metoclopramide versus dexketoprofen trometamol versus metoclopramide+ dexketoprofen trometamol in patients presenting with acute migraine attack to the emergency department (ED). METHODS: This single-center, randomized, double-blind study was conducted in a tertiary care ED. Eligible patients met the migraine criteria of the International Headache Society were randomized to receive 10 mg intravenous metoclopramide, 50 mg intravenous dexketoprofen trometamol, or 50 mg dexketoprofen trometamol +10 mg metoclopramide. Visual analogue scale (VAS) was used for pain measurement at baseline, after 15 and 30 min. The primary outcome measure was the changes in the VAS scores at the 15th and 30th minutes of treatment. The secondary outcome measures were the presence of adverse effects and the requirement of rescue medicine. RESULTS: Patients (n = 150) were randomized into 3 groups with similar VAS scores at baseline. While there was no significant difference between metoclopramide and dexketoprofen trometamol in reducing pain at the 15th and 30th minute (p = 0.618 and p = 0.862, respectively) and between metoclopramide and metoclopramide + dexketoprofen trometamol at the 15th minute (p = 0.074), metoclopramide + dexketoprofen trometamol was superior to both metoclopramide [mean difference: -13.2 mm (95% CI -23.1 to -3.3)] and dexketoprofen trometamol [mean difference: -11.02 mm (95% CI -20.9 to -1.1)] at the 30th min (p = 0.006 and p = 0.025 respectively). The rescue drug was required by 3 patients (6%) were in metoclopramide group, 4 patients (8%) in dexketoprofen trometamol group and one patient (2%) in the metoclopramide + dexketoprofen trometamol group. No side effects were observed in subjects in three treatment groups. CONCLUSION: No significant difference in VAS was found between three treatment groups at the 15th minute, but metoclopramide + dexketoprofen trometamol was superior to both metoclopramide and dexketoprofen trometamol at the 30th min.

Functionalization of gum arabic including glycoprotein and polysaccharides for the removal of boron.

Bio hybrid material supported multifunctional (hydroxyproline with enriched glycoprotein) has been shown to be efficient in chelation with boron and can be used for removal of boron at ppm levels. Gum arabic (GUM) is biodegradable and nontoxic biopolymer. GUM includes GA-GP-GA-glycoprotein and polysaccharides. Hollow silica spheres (HSS) gain increasing attention, thanks to low density, high specific surface and good adsorption performance. In this study, sol-gel process was used for the preparation of HSS and was modified with epoxy group. The resulted epoxidized HSS (HSEPC) was reacted with GUM to obtain a poly saccharide derivative functional hollow silica sphere (HSGUM) for removal of boron. Characterizations of HSGUM were performed by FT-IR and SEM techniques. Adsorption isotherm and kinetic models were also applied to adsorption of boron onto HSGUM. The resulting sorbent HSGUM has been demonstrated efficient and the maximum boron sorption capacity at monolayer coverage (qmax) was found as average 4.10 mmol g-1.

A Novel Protocol to Generate Decellularized Bovine Spinal Cord Extracellular Matrix-Based Scaffolds (3D-dCBS).

Extracellular matrix (ECM)-based tissue engineering scaffolds have an essential role in promoting tissue regeneration. Nerve tissue engineering aims at facilitating the repair of permanent damage to the peripheral and central nervous systems, which are difficult to heal. For this purpose, a variety of biomaterials are being developed consisting of numerous synthetic and/or natural polymers to provide axonal reinnervation and to direct the growth of axons. Here, we present a novel protocol that enables to fabricate a 3-dimensional (3D) decellularized scaffold derived from the bovine spinal cord (BSC) ECM (3D-dCBS) for neural tissue engineering applications. In this protocol, a viscous ECM-derived gel from BSC is prepared, molded, and chemically crosslinked with EDC/NHS (3D-CBS) before decellularization process. Decellularization of 3D-CBS is performed with 1% SDS to attain 3D-dCBS. As compared with other available methods, our protocol is a novel decellularization method that preserves a more significant part of the ECM. We believe that the mentioned protocol has the potential to produce a bioengineered scaffold from spinal cord tissue with desired geometry for regenerative medicine applications related to neural tissue engineering.

Treatment of resistant idiopathic hiccups with pulse radio frequency on phrenic nerve and gabapentin: A case report.

Hiccups affect life quality, career and family life when they become persistent. We present here a 54-year-old man who worked as a mason and a blacksmith with hiccups complaint for nearly one and a half years. In this period, he was admitted to emergency service ten times with fainting or almost fainting, cold sweating and hand stretching complaints. The patient expressed that he frequently threw up when he had hiccups and his social life was negatively affected. He reported that he was treated with baclofen, esomeprazole and hyoscine-n-butyl bromur without relief. He used escitalopram and chlorpromazine for a short time and quit because they negatively affected his sleeping. As he did not have any relief from medications, he refused any oral medical therapy including gabapentin and started to seek remedy from paramedical treatments resulted with no benefit. The patient was referred to algology department and an intervention on phrenic nerve with pulse radio frequency (8 minutes, 45 Volts, 20 milliseconds wavelength) was performed. Symptoms stopped immediately after the procedure but one week later, although the patient reported a significant decline in symptoms he still had hiccups. The patient was offered oral medical therapy again. With considerable relief from symptoms, the patient accepted oral therapy this time. Gabapentin 300 mg bid was prescribed. The symptoms were completely recovered and the patient reported no hiccups after 30 days of Gabapentin administration. Our case suggests that administration of gabapentin after pulsed radiofrequency might be effective for the treatment of persistent hiccups.

Serum obestatin and omentin levels in patients with diabetic nephropathy.

INTRODUCTION: Diabetic nephropathy is the leading cause of chronic kidney disease and accounts for almost 45% of all new patients requiring renal replacement therapy. Omentin and obestatin, two novel proteins were suggested to be associated with insulin resistance, type 2 diabetes and cardiovascular risk factors. Thus, we postulated that they may also have an association with diabetic nephropathy which is known to be an independent cardiovascular risk factor. In order to investigate such an association we compared serum omentin and obestatin levels in type 2 diabetic patients with normoalbuminuria (NA) and macroalbuminuria (MA). MATERIALS AND METHODS: A total of 81 type 2 diabetic patients were separated into two groups according to their proteinuria status; patients with NA (n = 39) and patients with MA (n = 42). Two groups were compared in terms of serum omentin and obestatin levels. RESULTS: While s erum omentin levels did not differ among two groups (P = 0.407), serum obestatin levels were significantly higher in MA group (P = 0.001). CONCLUSION: The results of this study showed that higher serum levels of obestatin were associated with macro albuminuria suggesting that obestatin may have a role in underlying pathogenic mechanisms that leads to diabetic nephropathy.

Parental beliefs and practices regarding childhood fever in Turkish primary care.

BACKGROUND: Fever is a very common problem in pediatric age and is one of the most common reasons parents seek medical attention. We aimed to investigate beliefs, habits, and concerns of Turkish parents regarding their children's fever. MATERIALS AND METHODS: We performed a cross-sectional survey which was conducted as face-to-face interviews by family physicians from April to June 2014 in family healthcare centers in nine different cities in Turkey. Parents with a child with fever aged between 0 and 14 years were interviewed. The participants were asked questions about sociodemographic data, the definition and measurement of fever, antipyretics, and other interventions used to reduce fever before presenting to the primary care center. RESULTS: A total of 205 parents participated in this study. Ninety-four parents (45.8%) measured fever with a thermometer prior to presentation. Only 36 parents (38%) used the thermometer correctly. Thirty-eight parents (18.5%) knew the correct temperature definition of fever for the measured site. A mercury-in-glass thermometer was the choice for most parents (78%) and preferred site for measurement was axillary region (85%). The fever was treated prior to arrival by 171 parents (83.4%). Paracetamol was the most frequently used antipyretic. Fifty-four parents (31.5%) failed to administer the correct antipyretic dose, and 73 parents (42.6%) failed to give the antipyretics at proper intervals. One hundred and fifty-three parents (67%) believed that if not treated fever could cause convulsions. CONCLUSION: We conclude that parents share important misconceptions about definition, treatment, and consequences of childhood fever and tend to treat fever before seeking medical care with a substantial rate of wrong doses and wrong intervals.

Factors affecting uptake of influenza vaccination among family physicians.

AIM: The aim of this study was to determine the factors that influenced the decisions of family physicians working in primary care health services to receive influenza vaccines. METHODS: This cross-sectional study was performed between June 2014 and September 2014. Physicians were reached electronically via e-mail. A self-reported questionnaire consisting of 50 items covering potential factors that may have influenced their decision to receive vaccination, including perceived risk, severity of the perceived risk, perceived benefit, perceived barriers, cues to action, attitudes, social influences and personal efficacy, was administered to the study participants. Cronbach's alpha for the questionnaire was determined to be 0.92 in the pilot study. RESULTS: The response rate was 27.5% (n=596). Regularly vaccinated physicians accounted for 27.3% of the responses. The median age was 41.84±7.80, and the median working duration of the group was 17.0±7.8years. The factors that led to increased vaccination compliance (p<0.05) included working duration, age, chronic disease history and living with a person over 65years. Nearly all major domains, i.e., perceived risk, severity of the perceived risk, perceived benefit, perceived barriers, attitudes, social influences and personal efficacy, there were differences between the compliant and noncompliant groups. Multi-regression analyses revealed that risk perception, organizational factors such as time and convenient vaccination increased vaccine compliance. However, the perceived necessity to be vaccinated annually had a negative effect on vaccination behaviour (p<0.05). CONCLUSION: Strategies aimed to increase the flu vaccination ratio among physicians that do not take different factors into account are more likely to be unsuccessful. In the planning and implementation of strategies aiming to increase the vaccination ratio among physicians, it is both necessary and important to take into account behavioural and organizational factors.

Preoperative chemotherapy for T2 breast cancer is associated with improved surgical outcome.

BACKGROUND: The aim of this study is to compare the clinical outcome in T2 breast cancer patients who underwent preoperative chemotherapy (PC) and who did not. The study also tried to define a subgroup of patients, who are more beneficial after PC in terms of lower re-excision rates, better cosmetic results and local recurrence free survival. MATERIALS AND METHODS: 251 consecutive patients treated for nonmetastatic T2 invasive breast cancer were analyzed retrospectively. Of those; 141 underwent primary surgery (PS) followed by chemotherapy, whereas 110 were treated with combination of PC and surgery. RESULTS: The patients who were treated with PC had a significantly higher incidence of negative margins and lower rate of re-excision (5% vs. 16%, p = 0.02). Of all patients attempted breast conserving surgery (BCS), patients in the PC group were more likely to undergo BCS as their definitive operation compared to patients with PS group (BCS rates; PC group: 99% vs. PS group: 92%, p = 0.05). Multifocal disease (OR: 7, 95% Cl, 2.7-18.4, p = 0.0001) and PC (OR = 0.2; 95% CI, 0.06-0.72, p = 0.01) were factors associated with margin positivity in patients treated with BCS. There was no statistically significant difference in 5 year local-recurrence free survival rates between 2 groups. CONCLUSIONS: Our study shows that PC significantly decreases the re-excision in patients undergoing BCS with primary T2 breast tumors. This data suggests that any patient with a tumor greater than 2 cm might be considered for PC to increase BCS success with final negative margins.

The effect of internal mammary lymph node biopsy on the therapeutic decision and survival of patients with breast cancer.

BACKGROUND: The role of internal mammary lymph node biopsy (IMLNB) is still being discussed in breast cancer treatment. The aim of this study was to investigate the role of IMLNB on adjuvant therapy and survival of patients with breast cancer. PATEINTS AND METHODS: The data of 72 patients with clinically negative axilla and IMLNB were evaluated. IMLNB was performed either through a small separate intercostal incision or from the same incision for tumor resection or mastectomy by using both blue dye and radioisotope. Pathological analysis was performed on formalin-fixed paraffin-embedded tissues. RESULTS: Ten of the patients (14%) were IMLNB-positive. The axillary sentinel lymph node and IMLN were negative in most of the patients (52.8%). In one patient (1.4%), the axilla was negative but the IMLNB was positive. IMLNB changed the pathologic stage in eight patients (11%). Adjuvant internal mammary radiotherapy was added to the treatment protocol for 10 patients due to IMLNB positivity and adjuvant chemotherapy was added in for only one patient with negative axilla. The factors found to be related with IMLN positivity were SLN positivity (p = 0.033), mastectomy (p = 0.022), and the number of resected IMLN ≥2 (p = 0.040). The median follow-up time was 115.5 months (range, 30-162 months). The ten-year overall survival (OS) rate was 86%. Systemic metastasis (p = 0.007), SLNB positivity (p < 0.001), and IMLNB positivity (p = 0.005) were statistically related to overall survival. CONCLUSION: IMLNB positivity in patients with breast cancer changed the pathologic stage and adjuvant treatment modalities of patients and also adversely affected the overall survival.

Erdheim Chester disease presented isolated breast and axillary involvement.

Erdheim-Chester disease (ECD) is a rare non-Langerhans cell histiocytosis of unknown aetiology. The most common sites of involvement are the long bones, skin, orbit, pituitary and retroperitoneal space. Isolated breast involvement is rare in the literature. ECD of the breast has been rarely reported. ECD should be considered in the differential diagnosis of histiocytoid breast lesions, including fat necrosis and histiocytoid invasive mammary carcinoma. In this case report, we present an unusual presentation isolated breast involvement of ECD with radiological and histopathology findings.

Placental site trophoblastic tumor: report of a tertiary center experience.

OBJECTIVE: To analyze the clinical and pathological characteristics of placental site trophoblastic tumor (PSTT) cases and to discuss the diagnosis, treatment, and prognosis of PSTT. MATERIALS AND METHODS: The clinical and pathological data of eight patients with PSTT at Istanbul Medical Faculty Hospital from 1988 to 2010 were analyzed retrospectively. RESULTS: The mean age of the patients was 31 years. The antecedent pregnancy was full-term delivery in most of the patients (6/8, 75%). The mean interval from last pregnancy to diagnosis of PSTT was 35 months (range, six to 192). Serum human chorionic gonadotropin (hCG) levels at the time of diagnosis ranged from 0.1 to 2280 mIU/ml (mean, 614). All patients had Stage 1 disease and ultimately underwent hysterectomy. None of the patients received adjuvant chemotherapy. One patient died of an unknown reason, one month after the surgery. The rest of the patients were alive and without evidence of disease after an average of 3.5 years (range, one to 11) of follow-up. CONCLUSION: Hysterectomy alone can provide long-term survival in early-stage disease.

Drugs with anticholinergic side-effects in primary care.

BACKGROUND: Anticholinergic drugs in elderly people have been associated with some serious side-effects. Patients in Turkey tend to attend primary care centers to have prescriptions of the drugs they chronically use. However, very little are known about how frequent that these drugs are prescribed and their side-effects in Turkish population. We aimed to investigate the usage and side-effects of drugs with anticholinergic properties in patients over 65 years of age attending to primary care centers. MATERIALS AND METHODS: Five hundred and sixty-three subjects were interviewed with a questionnaire of 16 questions inquiring their medication and possible side-effects. Timed up and go test (TUGT) and standardized mini-mental test (SMMT) were also performed. RESULTS: Medical records of 563 individuals were screened to detect anticholinergic medication. Twenty-eight patients were using anticholinergic medication. Mean duration of anticholinergic medication usage was 3.17 years. Mean number of falls occurred in the previous year was 1.14 ± 1.17. Mean SMMT score was 27.20 ± 1.13. Mean TUGT scores mean was 12.4 ± 1.25. Drowsiness in 18 patients (65%), dry mouth in 15 patients (53%), dry eyes in 15 patients (53%), constipation in 11 patients (39%), blurred vision in 11 patients (%39), urinary hesitancy in eight patients (28%), confusion in six patients (21%) were reported. We found that none of the subjects were evaluated in terms of fall risk or mental status by their doctors before the prescription of drugs with anticholinergic effects. CONCLUSIONS: A suggested approach to improve drug safety was reported as to reduce the use of anticholinergic drugs when it is possible. Psychiatrists and family physicians should select less anticholinergic drugs for medication and have to evaluate their patients' fall risk and their cognitive status before prescribing drugs with anticholinergic side effects.

Clinical and histopathologic predictors of reoperation due to recurrence of leiomyoma after laparotomic myomectomy.

OBJECTIVE: To assess clinical and histopathologic risk factors for reoperation after laparotomic myomectomy due to leiomyoma recurrence. METHODS: A case-control study was conducted of patients who underwent their first myomectomy for leiomyoma without receiving gonadotropin-releasing hormone analogues at Ankara University School of Medicine, Ankara, Turkey, between January 2000 and December 2004. Medical records and histopathologic samples were reviewed, and participants completed a telephone interview. Patients in the case group had undergone reoperation within 5 years; those in the control group had not required further surgery. RESULTS: There were 51 patients in the case group and 61 controls. The number of women who had given birth after the index surgery was lower among cases than controls (4 [7.8%] vs 13 [21.3%]; P=0.048), as was the median size of the largest leiomyoma removed (4 cm [range 3-10] vs 5 cm [range 3-25]; P=0.009). Reoperation was more likely among patients aged at least 40 years at index surgery (OR 1.10; 95% CI 1.18-7.78; P=0.021) and those with myxoid change (OR 2.04; 95% CI 1.07-55.41; P=0.043). The number of leiomyomas removed was negatively associated with reoperation (OR 0.30; 95% CI 0.58-0.93; P=0.012). CONCLUSION: Young age, removal of many or large leiomyomas, and pregnancy after myomectomy decreased reoperation risk, whereas myxoid change increased risk.

Elevated tissue levels of tumor necrosis factor-α in vulvar vestibulitis syndrome.

The purpose of this study was to compare levels of inflammatory cytokines, namely TNF-α, IL-1ß, and IL-1 receptor in women with vulvar vestibulitis syndrome (VVS) relative to levels in controls. The authors hypothesized that tissue concentrations of inflammatory cytokines would be elevated significantly in women with VVB compared to pain-free controls. The study population consisted of 15 women with strictly defined VVB in reproductive age and 13 age-matched women with no history of vulvodynia. For TNF-α, positive staining was observed in 40% of the samples from the study group and in 7.7% of the samples from the control group. The difference between the groups was statistically significant (p < 0.05). In conclusion, a limitation of the present study was the relatively small sam- ple size. However, the authors' intention was simply to propose that the local inflammation may be mediated by cytokines as TNF-α may rather than trying to single out a pathogenesis of VVS. The authors' findings of elevated TNF-α may suggest new therapeutic alternatives for VVS, as inhibiting cytokine synthesis or antagonism of the cytokine receptor.

Apoptosis through regulation of Bcl-2, Bax and Mcl-1 expressions in endometriotic cyst lesions and the endometrium of women with moderate to severe endometriosis.

The aim of the study was to evaluate apoptosis through regulation of Bcl-2, Bax and Mcl-1 proteins by comparing their expressions in endometriotic cyst lesions and the endometrium of the patients with moderate to severe endometriosis. This is a cross-sectional study of 30 women in reproductive age with a clinical or sonographic suspicion of endometrioma, who underwent laparoscopy. Bcl-2 expression was positive both in cystic endometriotic lesions and endometrium, and its expression was significantly reduced in the cystic endometriotic lesions (p < 0.0001). There was a significant difference in Bcl-2 expression between cystic endometriotic stromal cells and endometrial stromal cells (p < 0.0001). Bax expression was positive both in cystic endometriotic lesions and endometrium, and its expression was significantly lower in the endometrium (p < 0.0001). There was a significant difference in Bax expression between cystic endometriotic stromal cells and endometrial stromal cells (p = 0.03). Mcl-1 expression was positive both in cystic endometriotic lesions and endometrium, and its expression was significantly lower in the cystic endometriotic lesions (p = 0.003). Apoptosis may play a role in the pathophysiology of endometriosis by potentially contributing to the survival of regurgitating endometrial cells in the peritoneal cavity.

Placental mesenchymal dysplasia: a rare clinicopathologic entity confused with molar pregnancy.

Placental mesenchymal dysplasia (PMD) is a rare placental abnormality characterised by placentomegaly and grape-like vesicles resembling partial mole by ultrasonography, but in contrast to partial mole can co-exist with a viable fetus. Although the karyotype is normal, the fetus is at increased risk for intrauterine growth restriction, intrauterine fetal demise or perinatal death and Beckwith-Wiedemann syndrome. Prenatal diagnosis is difficult and the final diagnosis is usually achieved by postpartum histological examination of the placenta. We present two recent cases of placental mesenchymal dysplasia with poor obstetric outcome. One fetus presented with reduced growth parameters, while the other fetus showed hepatosplenomegaly and early hydropic changes that appear to be associated with Beckwith-Wiedemann syndrome. In this report, the clinico-pathological features of two cases of PMD are discussed and the differentiation from a partial mole is highlighted. This study also supports the utility of cytogenetic ploidy analysis and p57KIP2 protein staining in the evaluation of pregnancies with PMD.
