Benign cystic mesothelioma is an uncommon tumor arising from the peritoneal mesothelium. It is characterized by multilocular grapelike, thin-, and translucent-walled cysts, or a unilocular cyst lined by benign mesothelial cells. It occurs predominantly in women of reproductive age, and shows a predilection for the surface of the pelvic peritoneum or visceral peritoneum. Patients usually present...

A comparative light microscopic and scanning electron microscopic study of the morphogenesis of peritoneal metastasis in 34 human gastric cancers was performed. Prior to adhesion of gastric cancer cells to the peritoneum, the mesothelial cells became hemispherical and exfoliated from the peritoneum, and gastric cancer cells adhered to the naked areas of the submesothelial connective tissue. A f...

Peritoneal closure is a controversial issue among obstetricians and gynaecologists. This article reappraises the issue of peritoneal closure. We conducted a thorough literature search using Medline, Pubmed and Embase as well as a hand-search for all references quoted in the relevant papers. The routine non-closure of the peritoneum reduces operation time by an average of 6 min. Most studies sho...

Objective  To assess the frequency of surgical techniques at cesarean delivery (CD) among U.S. obstetricians. Methods  Members of the American College of Obstetrician Gynecologists were randomly selected and e-mailed an online survey that assessed surgical closure techniques, demographics, and reasons. Data were analyzed using SPSS (IBM Corp., Armonk, New York, United States), descriptive stati...

OBJECTIVE To evaluate, in a new original in vitro assay, putative factors that could modulate the adhesion of endometrial cells to peritoneum. DESIGN Prospective, controlled in vitro study. SETTING Academic research laboratory. PATIENT(S) Fourteen nonmenopausal women undergoing hysterectomy or laparoscopy for benign gynecologic indication. INTERVENTION(S) Endometrial cells obtained from...

BACKGROUND Peritoneum metastasis of lung cancer is a rare event which, in addition to the peritoneum, usually involves multiple metastatic tissues. Here we report a case of a patient with lung adenosquamous cell carcinoma with the peritoneum as the sole distant metastatic site. CASE PRESENTATION An 82-year-old Han Chinese man, in the teaching profession, was diagnosed with lung adenosquamous ...

Different T cell subsets exhibit distinct capacities to migrate into peripheral sites of inflammation, and this may in part reflect differential expression of homing receptors and chemokine receptors. Using an adoptive transfer approach, we examined the ability of functionally distinct subsets of T cells to home to a peripheral inflammatory site. The data directly demonstrate the inability of n...

Re-implantation techniques of extracted parathyroid tissue were developed in order to prevent temporary hypocalcemia. During thyroid surgery; inadvertently removed or devascularized parathyroid gland is usually implanted in the sternocleidomastoid muscle. In this experimental study using rats with hypoparathyroidism, our aim was to investigate whether the excised parathyroid tissue could be see...

BACKGROUND Endometrium can adhere to autologous peritoneum. This study was undertaken to determine the effect of the menstrual cycle phase and the presence and stage of endometriosis on in-vitro adhesion of endometrium onto autologous peritoneum. METHODS This was performed in an academic medical research centre. Sixty-seven subfertile women with a visually normal pelvis (n = 18) and with biop...

BACKGROUND The epidemiology of metastatic gastric cancer is unexplored because cancer registries seldom cover metastatic involvement apart from "present or not". We used a novel approach by utilizing Swedish registers to assess metastatic spread in gastric cancer. To our knowledge, this is the first nationwide description of metastases in gastric cancer. RESULTS The most common sites of metas...
