ABSTRACT

Ovotesticular disorder represents 10% of cases of disorder of sex development characterized by the presence of both ovarian and testicular tissue in the same individual, with karyotype 46 XY being a rare sex chromosomal abnormality. We report the case of a 16-year-old person, who is reared as female, with a complaint of primary amenorrhea along with lack of secondary sexual characteristics, karyotype 46 XY. Prophylactic bilateral gonadectomy was done, and histopathological examination of bilateral gonads revealed ovarian stroma with a few Sertoli cell line tubules suggestive of bilateral ovotestis; hence, we concluded and framed our diagnosis of ovotesticular disorder.

ABSTRACT

Premenopausal bilateral ovariectomy is considered to be one of the risk factors of Alzheimer's disease (AD). However, the underlying mechanisms remain unclear. Here, we aimed to investigate long-term neurological consequences of ovariectomy in a rodent AD model, TG2576 (TG), and wild-type mice (WT) that underwent an ovariectomy or sham-operation, using in vivo MRI biomarkers. An increase in osmoregulation and energy metabolism biomarkers in the hypothalamus, a decrease in white matter integrity, and a decrease in the resting-state functional connectivity was observed in ovariectomized TG mice compared to sham-operated TG mice. In addition, we observed an increase in functional connectivity in ovariectomized WT mice compared to sham-operated WT mice. Furthermore, genotype (TG vs. WT) effects on imaging markers and GFAP immunoreactivity levels were observed, but there was no effect of interaction (Genotype × Surgery) on amyloid-beta-and GFAP immunoreactivity levels. Taken together, our results indicated that both genotype and ovariectomy alters imaging biomarkers associated with AD.

ABSTRACT

Objective@#The primary objective of this study was to establish the presence of nerve fibers in the eutopic endometrium of women with endometriosis and to determine whether these nerve fibers are exclusive to endometriosis or are also found in other pelvic pathologies associated with dysmenorrhea. @*Methods@#Endometrial tissue was obtained by aspiration (Pipelle), endometrial curettage, or following hysterectomy in women with endometriosis confirmed through histopathological examination, leiomyomas, and adenomyosis. The eutopic endometrium was subjected to immunohistochemical staining to detect PGP 9.5, which is a highly specific pan-neuronal marker. The nerve fiber density was correlated with the patient’s pain score, as indicated by the Visual Analog Scale. A control group was formed by staining the endometrium of women presenting with dysmenorrhea but without the above-mentioned disorders. @*Results@#Nerve fibers were observed in sections of the endo-myometrium (in the deep endometrium) in 68% of patients with endometriosis who underwent hysterectomy or a deep endometrial biopsy. Nerve fibers were not observed in the aspirated endometrium of women with endometriosis. Only 13.7% of women with adenomyosis and 3.3% of women with fibroids had nerve fibers in their endometrium. Nerve fiber density was correlated with pain score in women with endometriosis. @*Conclusion@#Nerve fibers were found in the functional layer of eutopic endometrium in women with endometriosis; hence, we concluded that the presence of nerve fibers in the eutopic endometrium could diagnose endometriosis with a fairly good specificity of 92.7%. However, the absence of nerve fibers does not always exclude the disease.

ABSTRACT

Objective@#To determine the incidence of accidentally diagnosed genital malignancies in women undergoing gynecological surgeries for pathologies presumed to be benign. @*Methods@#Data of all women who underwent hysterectomy for benign indications were retrieved from hospital records. A total of 628 cases of hysterectomy and 35 cases of myomectomy were included. The final histopathology was accessed through the computer records, and the total number of genital tract malignancies was included. @*Results@#The incidence of occult uterine, ovarian, and cervical malignancies in women undergoing hysterectomy was 0.47%, 0.31%, and 0.15%, respectively. The incidence of uterine corpus malignancies in women undergoing myomectomy was 2.8%, and 3 cases of smooth muscle tumor of uncertain malignant potential (STUMP) were also identified. Endometrial stromal sarcomas were the most common pathology among uterine malignancies, followed by leiomyosarcoma and endometrial adenocarcinoma. @*Conclusion@#Postoperative diagnosis of malignancies in women undergoing surgery for benign indications poses great challenges to the treating surgeon. Occult malignancies must be ruled out by thorough preoperative assessment, especially in some subsets of women. Morcellation is an inevitable technique and complement to laparoscopic surgeries, although little chances of malignancy spread is related to its use. Nevertheless, thorough preoperative investigations and always ensuring contained morcellation can minimize these chances.

ABSTRACT

AIM: To evaluate the tissue eosinophilia in different stages and grades of oral squamous cell carcinoma (OSCC) and correlate its possible role as a prognosticator in primary OSCC using special stains like Congo red and carbol chromotrope. MATERIALS AND METHODS: Forty-five intraoral histopathologi-cally proven cases of OSCC were selected (15 cases each of well-differentiated squamous cell carcinoma (WDSCC), moderately differentiated squamous cell carcinoma (MDSCC), and poorly differentiated squamous cell carcinoma (PDSCC)). Three sections of 4 pm were taken for each case. All slides were stained using routine stain, i.e., hematoxylin and eosin (H&E), and special stains, i.e., carbol chromotrope and Congo red respectively, for studying tissue eosinophils in all these groups. Histopathological evaluation was performed on paraffin sections for calculating the quantitative eosinophil distribution by two separate observers who were blinded to clinical and histopathological data. Tumor-associated tissue eosinophilia (TATE) was calculated using the density method. RESULTS: An increase in the degree of TATE from stage I to stage IV suggested that elevated tissue eosinophilia was seen with an increasing size of primary tumor. Also an increase in TATE was observed with an increasing grade of OSCC. Chromotrope stain was found to be a much better and more specific stain for eosinophils, and gave more accurate eosinophil count compared with H&E and Congo red. CONCLUSION: The findings of the present study highlight the significance of eosinophil counting and that it can be used as an additional morphological parameter in the grading of OSCC which can also be included in the biopsy report.
