    The spotted paca is the second largest rodent in Brazil, where it is of great economic interest in impoverished regions in view of its prominence as a low-cost source of protein. Little is known about the morphology of the accessory genital glands of this species. Thus, we studied the position and morphology of the genitals in ten adult male spotted pacas. The animals were divided into two groups, five animals were used for fixing of samples in 10% aqueous formaldehyde for macroscopic studies and the other five animals were designated for microscopic analysis. These were arranged in pairs and had the vesicular, prostate, coagulating and bulbourethral glands identified, being structured as mucous glands, which lead into the pelvic urethra. It was concluded that the accessory genital glands found in the paca are the same as those found in most rodents, showing similar histological aspects.

    Autonomic nerves supplying mammalian male internal genital organs have an important role in the regulation of reproductive function. To find out the relationships between the neurochemical content of these nerves and the reproductive activity, we performed a histochemical and immunohistochemical study in a species, the water buffalo, exhibiting a seasonal sexual behaviour. The distribution of noradrenergic and nitric oxide synthase (NOS)- and peptide-containing nerves was evaluated during the mating and non-mating periods. Fresh segments of vas deferens and accessory genital glands were collected immediately after slaughter and immersed in 4% paraformaldehyde. Frozen sections were obtained and processed according to single and double labelling immunofluorescent procedures or NADPH-diaphorase histochemistry. During the mating period, a dense noradrenergic innervation was observed to supply the vas deferens as well as the accessory genital glands. NOS- and peptide-containing nerves were also observed but with a lower density. During the non-mating period noradrenergic nerves dramatically reduced. In addition, neuropeptide Y (NPY)- and vasoactive intestinal peptide (VIP)-containing nerves were also reduced. These findings suggest the presence of complex interactions between androgen hormones and the autonomic nerve supply in the regulation of male water buffalo reproductive functions.

    Tumors of accessory parotid gland are considered in the differential diagnosis of a mid cheek mass. Parotidectomy is the procedure of choice. All pathological types of parotid main gland tumors occur in the accessory parotid gland also. Presenting as a mid cheek or infrazygomatic mass, the tumors of this accessory parotid gland are notorious for recurrences, if adequate margins are not achieved. We describe two such cases of such a tumor. 40-year-old male with a slowly progressive mid cheek mass was operated by a mid cheek incision. Histopathology of the tumor was pleomorphic adenoma. Facial nerve paresis recovered complelety in 6 months. A 52-year-old female with progressive mid cheek mass who underwent parotidectomy and neck dissection by a modified Blair's incision was diagnosed with extranodal marginal zone lymphoma with focal transformation to a diffuse large B-cell lymphoma. Chemotherapy with CHOP regime was initiated. There was no recurrence at 6 months of follow-up. Lymphoma of accessory parotid gland is a very rare tumor. Standard parotidectomy incision is advocated to prevent damage to facial nerve branches. PMID:23483721

    The suprarenal glands are normally located at the superomedial aspect of the kidneys. Accessory cortical masses are seen in approximately half of the newborn but usually disappear later. Several cases with accessory cortical tissues located near the main suprarenal glands have been reported but their usual locations have been rarely described. Here we report a case with accessory cortical tissue located on the right in the retrocrural space with compression symptoms. Such a lesion may be confused with lymphadenopathy radiologically.

    We report a rare case of sialolithiasis of an accessory parotid gland, which was located anteromedial to the masseter muscle and isolated from the main parotid gland. The calculus developed from this accessory gland, and the main gland was free of lithiasis and inflammation. To our knowledge, there is no reported case of 14 stones in an accessory parotid salivary gland. The calculus was removed through a standard incision without injury to the facial nerve or a salivary fistula. PMID:26048098

    Accessory parotid gland is a small salivary gland tissue separated from main part of parotid gland. It is located on the masseter muscle anterior to the Stensen's duct. Tumors of accessory parotid gland are rare. In this article, we report an unusual case of adenoid cystic carcinoma involving accessory parotid gland. The patient presented with a progressively growing mass in the middle portion of her cheek. She underwent a partial parotidectomy including both the superficial and accessory lobes. The histopathologic diagnosis was adenoid cystic carcinoma of cribriform type. PMID:26476520

    Benign oncocytomas of the accessory lacrimal glands can be found in the lacrimal caruncle, plica semilunaris or conjunctival fornices, but are extremely rare. A series of 15 supposed oncocytomas of the ocular adnexa was reviewed retrospectively, and histological differences were noted with respect to the parotid gland counterpart. Lesions could be divided into three histological groups: (1) tumours composed of tubules lined by tall columnar epithelium with finely granular cytoplasm; the tubules often had dilated lumens containing mucinous secretion; (2) cystic tumours with prominent epithelial tufts projecting from much of the cyst wall; (3) tumours with solid areas composed of variably cuboidal or polygonal cells, largely in trabecular arrangement, and co-existing with the previously described tubular and cystic elements. A striking resemblance to Warthin's tumour without a lymphocytic component, such as may affect the parotid salivary gland, was noted in several tumours.

    In complete series of histological sections through the entire abdomen of one normal Wistar-rat, one untreated and two bilaterally adrenalectomized, spontaneously hypertensive Wistar-rats accessory suprarenal glands were found in each case. The detailed findings in the various groups of animals investigated were as follows: (1) In the normal animal 10 accessory suprarenal glands were present. They consisted of tiny aggregates of cortical cells and were surrounded by a thin layer of collageneous fibers. The diameters of the accessory suprarenal complexes were in the order of 0.3 mm. (2) In the untreated, spontaneously hypertensive rat three accessory suprarenal glands were found. However, in contrast to what was seen in the normal rat, these complexes were larger and had diameters of up to 1 mm. Some of these accessory suprarenal glands consisted almost exclusively of small, chromophobe cells, whereas in others a rim of such cells was seen to surround a central core of larger and more acidophile cortical cells. There were few and collapsed capillaries. (3) In the bilaterally adrenalectomized, spontaneously hypertensive rats three, respectively four, accessory suprarenal glands were found. They were situated in the retroperitoneum and partly within the adipose capsule of the kidney but never in the place of the exstirpated main suprarenal glands. In one case an accessory gland was found within the fibrous capsule of the kidney and seen to compress the renal parenchyma. In the bilaterally adrenalectomized animals the average diameters of the accessory glands were larger than in the other groups reaching values of up to 5 mm. At least in both animals one of the accessory glands had a diameter comparable to that of the normal suprarenal gland of an untreated animal. The capillaries were dilated and their number was increased in comparison to what was seen in the other groups. In certain regions the cortical tissue of the accessory glands had an appearance resembling

    Accessory parotid gland tissue has been described as salivary tissue adjacent to the Stensen duct that is distinctly separate from the main body of the parotid gland. Of all parotid gland tumors, 1% to 8% arise from the accessory parotid gland. Little is known about the accessory parotid gland, and it is seldom mentioned in the literature. Between 1999 and 2010, we have treated and followed 8 patients with tumors of the accessory parotid gland. There were 5 males and 3 females with a mean age of 35 years. They all presented with an asymptomatic cheek mass, and 4 of them underwent fine-needle aspiration. Ultrasound or computed tomographic scan was used in all patients. All the patients underwent surgical intervention with standard parotidectomy incision and anterior extension. The mean follow-up time was 44 months (range, 6-120 months). Seven patients had benign disease. Four cases were pleomorphic adenoma, and the remaining 3 benign cases were parotid cyst, basal cell adenoma, and hemangioma. Only 1 patient had a malignant tumor that was a lymphoepithelioma-like carcinoma. In 7 cases, wide excision (excision of mass and accessory lobe of the parotid gland) was done because of the intra-accessory parotid gland lesion. One patient had concomitant superficial parotidectomy because the tumor was located very close to and has involved the parotid gland proper. There was no serious postoperative complication and recurrence. Prudent preoperative diagnostic evaluation and meticulous surgical approach are the keys to successful management of midcheek lesions. A wide excision of the accessory lobe of the parotid gland can be a definitive surgery in case of solitary tumor with an intact parotid fascia, and wide excision with anterior approach through a standard parotidectomy incision is preferred to a direct incision over the mass.

  10. Alternative delivery of male accessory gland products

    PubMed Central

    2014-01-01

    To increase fertilization success, males transfer accessory gland products (Acps). Several species have evolved unconventional Acps transfer modes, meaning that Acps are transferred separately from the sperm. By surveying the sperm-free Acps transfer cases, we show that these animals have evolved a common strategy to deliver Acps: they all inject Acps directly through the partner’s body wall into the hemolymph. Our review of this mode of Acps transfer reveals another striking similarity: they all transfer sperm in packages or via the skin, which may leave little room for Acps transfer via the conventional route in seminal fluid. We synthesise the knowledge about the function, and the effects in the recipients, of the Acps found in the widely diverse taxa (including earthworms, sea slugs, terrestrial snails, scorpions and salamanders) that inject these substances. Despite the clearly independent evolution of the injection devices, these animals have evolved a common alternative strategy to get their partners to accept and/or use their sperm. Most importantly, the evolution of the injection devices for the delivery of Acps highlights how the latter are pivotal for male reproductive success and, hence, strongly influence sexual selection.

    We used light and transmission electron microscopy to examine the morphology of the accessory glands of immature and mature adult males of Apis mellifera L. We also made an electrophoretic analysis of the protein content of the mature gland. The glands of the immature male actively secrete a mucous substance that can be seen in the lumen of the gland of the mature male. This secretion stains with mercury bromophenol blue and with periodic acid-Schiff reaction, which stain glyconjugates. The protein content was higher in the lumen secretion than in the gland wall extracts. The electrophoresis patterns of the wall extracts were different from those of the secretion found in the gland lumen.

    A 26-year-old woman presented with right breast pain and itching. Incidentally, a firm, non-tender, movable mass (3 cm in diameter) located in the lower right part of the neck was identified by palpation. Ultrasonography revealed a clearly demarcated dumbbell-shaped mass with homogenous hypo- (cranial side) and hyper-echogenicity (caudal side) compared with the thyroid gland. Computed tomography scan and magnetic resonance imaging presented images that were different from thyroid gland substance. The right thyroid lobe was strongly compressed by the mass. Hyperparathyroidism was ruled out by laboratory testing. The patient solicited resection of the mass despite recommendations for core needle biopsy, and it was removed surgically. The mass was surrounded by a thin capsule and was not connected with the thyroid gland. Pathological examinations revealed normal thyroid gland tissue. The final diagnosis was an accessory thyroid gland. Accessory thyroid glands should be considered as a possible diagnosis when nodules around the main thyroid gland are encountered.

    Accessory reproductive gland proteins (Acps) in Drosophila evolve quickly and appear to play an important role in ensuring the fertilization success of males. Moreover, Acps are thought to be involved in establishing barriers to fertilization between closely related species. While accessory glands are known to occur in the males of many insect groups, the proteins that are passed on to females by males during mating have not been well characterized outside of Drosophila. To gain a better understanding of these proteins, we characterized ESTs from the accessory glands of two cricket species, Allonemobius fasciatus and Gryllus firmus. Using an expressed sequence tag (EST) approach, followed by bioinformatic and evolutionary analyses, we found that many proteins are secreted and, therefore, available for transfer to the female during mating. Further, we found that most ESTs are novel, showing little sequence similarity between taxa. Evolutionary analyses suggest that cricket proteins are subject to diversifying selection and indicate that Allonemobius is much less polymorphic than Gryllus. Despite rapid nucleotide sequence divergence, there appears to be functional conservation of protein classes among Drosophila and cricket taxa.

    An accessory submandibular salivary gland is a rare anatomical variant, and a tumour within one is even rarer. We describe a 54-year-old man who presented with a slowly-enlarging mass in the right submandibular region which on magnetic resonance imaging (MRI) seemed to be close to, but not arising from, the right submandibular salivary gland. This was found to be a benign pleomorphic adenoma arising from an accessory submandibular salivary gland. To our knowledge it is only the second report of a pleomorphic adenoma that developed within an accessory submandibular salivary gland.

    This retrospective study aimed to identify if the existence of the accessory parotid gland correlated with the etiology of parotitis. This may aid the development of better treatment strategies in the future. Sialographic features of cases with parotitis and healthy subjects were reviewed. The chi-square test was used to compare the incidence of accessory parotid gland between the groups. The Student’s t test was used to compare the length of Stensen’s duct, the length from the orifice to the confluence of the accessory duct, and the angle between the accessory duct and Stensen’s duct between the groups. The incidence of accessory parotid gland in patients with parotitis was 71.8% (28/39), which was significantly higher than that in healthy subjects (P = 0.005). Patients with parotitis had a longer Stensen’s duct than healthy subjects (P = 0.003). There was no significant difference in the length from the orifice to the confluence of the accessory duct or the angle between the accessory duct and Stensen’s duct (P = 0.136 and 0.511, respectively) between the groups. The accessory parotid gland might play a role in the pathogenesis of parotitis. The existence of an accessory parotid gland is likely to interfere with salivary flow. Computational fluid dynamics analysis of salivary flow in the ductal system would be useful in future etiologic studies on parotitis. PMID:26913509

    Drosophila seminal proteins have an unusually high rate of molecular sequence evolution, suggesting either a high rate of neutral substitution or rapid adaptive evolution. To further quantify patterns of polymorphism and divergence in genes encoding seminal proteins, also called accessory gland proteins (Acp's), we conducted a sequencing survey of 10 Acp genes in samples of Drosophila melanogaster and D. simulans (Acp29AB, Acp32CD, Acp33A, Acp36DE, Acp53Ea, Acp62F, Acp63F, Acp76A, Acp95EF, and Acp98AB). Mean heterozygosity at replacement sites in D. simulans was 0.0074 for Acp genes and 0.0013 for a set of 19 non-Acp genes, and mean melanogaster-simulans divergence at replacement sites was 0.0497 for Acp genes and 0.0107 at non-Acp genes. The elevated divergence of Acp genes is thus accompanied by elevated within-species polymorphism. In addition to the already-reported departures of Acp26A, Acp29AB, and Acp70A from neutrality, our data reject neutrality at Acp29AB and Acp36DE in the direction of excess replacements in interspecific comparisons.

    The morphology and ultrastructure of female accessory reproductive glands of Anopheles maculipennis s.s., Anopheles labranchiae and Anopheles stephensi were investigated by light and electron microscopy. The reproductive system in these species is characterized by two ovaries, two lateral oviducts, a single spermatheca and a single accessory gland. The gland is globular and has a thin duct which empties into the vagina, near the opening of the spermathecal duct. Significant growth of the accessory reproductive gland is observed immediately after blood meal, but not at subsequent digestion steps. At ultrastructural level, the gland consists of functional glandular units belonging to type 3 ectodermal glands. The secretory cells are elongated and goblet shaped, with most of their cytoplasm and large nucleus in the basal part, close to the basement lamella. Finely fibrous electron-transparent material occupies the secretory cavity that is in contact with the end of a short efferent duct (ductule) emerging from the gland duct. The present study is the first detailed description of female accessory gland ultrastructure in Anophelinae and provides insights into the gland's functional role in the reproductive biology of these insects.

    In teleost fish sex steroids are essential for gonadal function and have marked effects in reproductive and agonistic behavior and in the expression of secondary sexual characteristics. The Lusitanian toadfish, Halobatrachus didactylus, has two male morphotypes: type I males are territorial nest-holders and have large accessory glands while type II males are smaller, have a relatively large testis and small accessory glands. In the present study, the steroidogenic activity of the testis and accessory testicular glands of the Lusitanian toadfish were examined in vitro as well as their presence in urine. The testis of type I males produced 11-ketotestosterone (11KT) and 11β-hydroxy-4-androstene-3,17-dione (11βA) from tritiated 17-hydroxyprogesterone, while those of type II males produced testosterone (T) and 11β,17β-dihydroxy-4-andosten-3-one (11βT), but not 11KT. Additionally, the testis and accessory glands of both morphs produced mostly 5β,3α-reduced and 17,20α-hydroxylated metabolites. Type I, but not of type II, males synthesised 5β-reduced androgens in their accessory glands. The presence of 11βA exclusively in the urine of type I males during reproductive season suggests an association with maintenance of secondary sexual characteristics and behavior in this morph. The urine of both types of males contained two 5α-androstane and 5β-pregnane glucuronides. Among the latter steroids, those that are 17,21-dihydroxylated are potentially metabolites from cortisol and were found only in type I males during the spawning season. The diversity of metabolites produced by the testis and accessory glands and the presence of some in urine is suggestive of a potential role in chemical communication and reproductive behavior.

    Aim: The present study was undertaken to study growth pattern of accessory sex glands in prepubertal kids from 2 weeks to 6 months of age using two-dimensional ultrasonography. Materials and Methods: The study was conducted on six Beetal kids. The scanning of accessory sex glands was done in standing position using rectal probe and measurements were recorded. Data collected were statistically analyzed using one-way ANOVA followed by Duncan multiple range test was performed using the SPSS (16.0) system for windows. Results: With the advancement of age all the dimensions of glands increased. Both the lobes of prostate gland showed an increase in width with advancement of age. Width of prostate above the urethra (W1) showed a significant increase at 2, 10, and 20 weeks of age, whereas non-significant increase from 2 to 8, 10 to 19, and 20 to 24 weeks of age was recorded. Width of prostate below the urethra (W2) showed a significant increase at 20 weeks of age, whereas non-significant increase was recorded during rest of period of growth. Left and right bulbourethral gland showed a similar pattern of growth with the advancement of age. The circumference dimensions increased significantly at 2, 16, 20, and 21 weeks of age for both glands. The increase was non-significant from 4 to 14, 16 to 19, and 20 to 23 weeks of age. The same pattern was observed for left and right seminal vesicular gland. Conclusion: Significant growth in three accessory sex glands in prepubertal kids was not observed at the same age. The trend observed was that the prostate was the first gland to show significant growth at 10 weeks of age followed by a significant increase in seminal vesicles and bulbourethral gland at 14 and 16 weeks of age, respectively.

    Ultrastructure of male reproductive accessory glands and ejaculatory duct in the Queensland fruit fly (Q-fly), Bactrocera tryoni, were investigated and compared with those of other tephritid flies. Male accessory glands were found to comprise one pair of mesodermic glands and three pairs of ectodermic glands. The mesodermic accessory glands consist of muscle-lined, binucleate epithelial cells, which are highly microvillated and extrude electron-dense secretions by means of macroapocrine transport into a central lumen. The ectodermic accessory glands consist of muscle-lined epithelial cells which have wide subcuticular cavities, lined with microvilli. The electron-transparent secretions from these glands are first extruded into the cavities and then forced out through small pores of the cuticle into the gland lumen. Secretions from the two types of accessory glands then flow into the ejaculatory duct, which is highly muscular, with epithelial cells rich in rough endoplasmic reticulum and lined with a thick, deeply invaginated cuticle. While there are some notable differences, reproductive accessory glands of male Q-flies generally resemble those of the olive fruitfly, Bactrocera oleae, and to a lesser extent the Mediterranean fruit fly, Ceratitis capitata.

    The most common conventional approaches for the resection of benign tumours in the accessory parotid gland are a standard parotidectomy incision, a modified standard parotidectomy incision, or a face-lift incision. The resulting scars may severely affect the patient's postoperative appearance. The previously reported endoscopically assisted approach offers a less aesthetically invasive technique, but it may still leave a visible preauricular scar 4-5 cm long. We have used a modified endoscopic approach with minimal, and concealed, incisions for the resection of benign tumours in the accessory parotid gland. Five patients were diagnosed by physical examination, imaging, and preoperative fine-needle aspiration biopsy. They had endoscopically assisted resections using our modified approach, and we evaluated its feasibility. All the resections were successful. The mean operating time was 108 min (range 90-130). The postoperative scars were concealed and aesthetically satisfactory. There were no facial paralyses, salivary fistulas, or recurrences in the short term. Using endoscopically assisted resection we completely removed benign tumours from the accessory parotid gland and obtained good aesthetic results. Our updated endoscopic approach for these resections is successful with shorter, concealed incisions. It is a viable alternative to conventional approaches.

    Insect steroid hormones (ecdysteroids) are important for female reproduction in many insect species and are required for the initiation and coordination of vital developmental processes. Ecdysteroids are also important for adult male physiology and behavior, but their exact function and site of synthesis remains unclear, although previous studies suggest that the reproductive system may be their source. We have examined expression profiles of the ecdysteroidogenic Halloween genes, during development and in adults of the flour beetle Tribolium castaneum. Genes required for the biosynthesis of ecdysone (E), the precursor of the molting hormone 20-hydroxyecdysone (20E), are expressed in the tubular accessory glands (TAGs) of adult males. In contrast, expression of the gene encoding the enzyme mediating 20E synthesis was detected in the ovaries of females. Further, Spookiest (Spot), an enzyme presumably required for endowing tissues with competence to produce ecdysteroids, is male specific and predominantly expressed in the TAGs. We also show that prothoracicotropic hormone (PTTH), a regulator of E synthesis during larval development, regulates ecdysteroid levels in the adult stage in Drosophila melanogaster and the gene for its receptor Torso seems to be expressed specifically in the accessory glands of males. The composite results suggest strongly that the accessory glands of adult male insects are the main source of E, but not 20E. The finding of a possible male-specific source of E raises the possibility that E and 20E have sex-specific roles analogous to the vertebrate sex steroids, where males produce primarily testosterone, the precursor of estradiol. Furthermore this study provides the first evidence that PTTH regulates ecdysteroid synthesis in the adult stage and could explain the original finding that some adult insects are a rich source of PTTH.

    Insect steroid hormones (ecdysteroids) are important for female reproduction in many insect species and are required for the initiation and coordination of vital developmental processes. Ecdysteroids are also important for adult male physiology and behavior, but their exact function and site of synthesis remains unclear, although previous studies suggest that the reproductive system may be their source.

    The evolutionarily conserved paired domain consists of the N-terminal PAI and the C-terminal RED domains, each containing a helix–turn–helix motif capable of binding DNA. Despite its conserved sequence, the physiological functions of the RED domain remain elusive. Here, we constructed a prd transgene expressing a truncated Paired (Prd) protein without the RED domain, and examined its rescue ability in prd mutants. We found that the RED domain is specifically required for the expression of Acp26Aa and sex peptide in male accessory glands, and the induction of female post-mating response. Our data thus identified an important physiological function for the evolutionarily conserved RED domain. PMID:25694546

    Male accessory gland proteins (Acps) act as key modulators of reproductive success in insects by influencing the female reproductive physiology and behavior. We used custom microarrays and identified 112 genes that were highly expressed in male accessory glands (MAG) in the red flour beetle, Tribolium castaneum. Out of these 112 identified genes, 59 of them contained sequences coding for signal peptide and cleavage site and the remaining 53 contained transmembrane domains. The expression of 14 these genes in the MAG but not in other tissues of male or female was confirmed by quantitative real-time PCR. In virgin males, juvenile hormone (JH) levels increased from second day post adult emergence (PAE), remained high on third day PAE and declined on fourth day PAE. The ecdysteroid titers were high soon after adult emergence but declined to minimal levels from 1-5 days PAE. Feeding of juvenile hormone analog, hydroprene, but not the ecdysteroid analog, RH-2485, showed an increase in size of MAGs, as well as an increase in total RNA and protein content of MAG. Hydroprene treatment also increased the expression Acp genes in the MAG. RNAi-mediated knock-down in the expression of JHAMT gene decreased the size of MAGs and expression of Acps. JH deficiency influenced male reproductive fitness as evidenced by a less vigor in mating behavior, poor sperm transfer, low egg and the progeny production by females mated with the JH deficient males. These data suggest a critical role for JH in the regulation of male reproduction especially through MAG secretions. PMID:19324087

    Mating success of male insects is commonly determined by their ability to find and copulate with multiple females, but is also determined by their ability to transfer an effective ejaculate. In order to succeed in these tasks, males must first succeed in replenishing the necessary reproductive reserves between mating opportunities. We here investigate the ability of male Queensland fruit flies ('Q-fly') to recover from their first matings in time to both mate again the following day and to induce sexual inhibition in successive mates. We have previously found that accessory gland fluids (AGFs) transferred in the ejaculate of male Q-flies are directly responsible for induction of sexual inhibition in their mates. We here investigate changes in male accessory gland, testis and ejaculatory apodeme dimensions that are likely to reflect depletion and recovery of contents. We found no differences between virgin and previously mated males in their ability to obtain matings or to induce sexual inhibition in their mates, indicating a full recovery of the necessary reproductive reserves between mating opportunities. Whereas no changes were detected in testis or ejaculatory apodeme size following mating, the recovery of male ability to inhibit female remating was closely reflected in the mesodermal accessory gland dimensions; these accessory glands greatly diminished in size (length and area) immediately after mating, with recovery commencing between 5.5 and 11 h after mating. The accessory glands then expanded to reach their original size in time to mate the following day and induce sexual inhibition in the next mate. PMID:18083187

    The objectives of this study were to evaluate the occurrence of Leishmania infantum in the male and female genital tract and female mammary glands of dogs and the parasite burden and to identify histological alterations associated with this protozoan. Twenty male and 20 female Leishmania-seropositive dogs with isolation of L. infantum were examined. Tissue samples of the prepuce, glans, epididymis, testes, prostate, vulva, vagina, uterus, uterine tubes, and mammary glands were analyzed by immunohistochemistry and histopathology. For parasitological culture and in situ hybridization, samples were collected from the testis, epididymis, and uterus. Additionally, seminal fluid was aspirated from the epididymis for parasitological culture. In the genital tract, 34 (85 %) dogs, including 18 males and 16 females, were positive for Leishmania. Of these, 27 (79 %) animals were symptomatic. Leishmania was detected in the mammary glands of 13 (65 %) females. L. infantum was isolated for the first time from the seminal fluid and uterus of naturally infected dogs. The parasite burden and intensity of the inflammatory reaction were greater in the prepuce and glans of males and in the vulva and mammary glands of females. In addition to inflammation, testicular degeneration, atrophy, absence of spermatogenesis, and necrosis were observed. Detection of amastigote forms in the mammary gland lumen indicates possible elimination of this parasite in milk. The frequent parasitism observed in the genital tract of infected males and females and the viability of L. infantum in seminal fluid and uterus suggest the possibility of bidirectional venereal and vertical transmission.

    Whereas in all other vertebrates the Müllerian ducts of genetic males are aborted during development, under the influence of Müllerian-inhibiting substance, in the caecilian amphibians they are retained as a pair of functional glands. It has long been speculated that the Müllerian gland might be the male accessory reproductive gland but there has been no direct evidence to this effect. The present study was undertaken to determine whether the caecilian Müllerian gland secretory proteins would bear antigenic similarity to secretory proteins of the prostate gland and/or the seminal vesicles of a mammal. The secretory proteins of the Müllerian gland of Ichthyophis tricolor were evaluated for cross-reactivity with antisera raised against rat ventral prostate and seminal vesicle secretory proteins, adopting SDS-PAGE, two-dimensional electrophoresis and immunoblot techniques. Indeed there was a cross-reaction of five Müllerian gland secretory protein fractions with prostatic protein antiserum and of three with seminal vesicle protein antiserum. A potential homology exists because in mammals the middle group of the prostate primordia is derived from a diverticulum of the Müllerian duct. Thus this study, by providing evidence for expression of prostatic and seminal vesicle proteins in the Müllerian gland, substantiates the point that in caecilians the Müllerian glands are the male accessory reproductive glands.

    For species in which mating is resource-independent and offspring do not receive parental care, theoretical models of age-based female mate preference predict that females should prefer to mate with older males as they have demonstrated ability to survive. Thus, females should obtain a fitness benefit from mating with older males. However, male aging is often associated with reductions in quantity of sperm. The adaptive significance of age-based mate choice is therefore unclear. Various hypotheses have made conflicting predictions concerning this issue, because published studies have not investigated the effect of age on accessory gland proteins and sperm traits. D. melanogaster exhibits resource-independent mating, and offspring do not receive parental care, making this an appropriate model for studying age-based mate choice. In the present study, we found that D. melanogaster females of all ages preferred to mate with the younger of two competing males. Young males performed significantly greater courtship attempts and females showed least rejection for the same than middle-aged and old males. Young males had small accessory glands that contained very few main cells that were larger than average. Nevertheless, compared with middle-aged or old males, the young males transferred greater quantities of accessory gland proteins and sperm to mated females. As a result, females that mated with young male produced more eggs and progeny than those that mated with older males. Furthermore, mating with young male reduced female's lifespan. These studies indicate that quantity of accessory gland proteins and sperm traits decreased with male age and females obtain direct fitness benefit from mating with preferred young males.

    The relationship between animal mating system variation and patterns of protein polymorphism and divergence is poorly understood. Drosophila provides an excellent system for addressing this issue, as there is abundant interspecific mating system variation. For example, compared to D. melanogaster subgroup species, repleta group species have higher remating rates, delayed sexual maturity, and several other interesting differences. We previously showed that accessory gland protein genes (Acp's) of Drosophila mojavensis and D. arizonae evolve more rapidly than Acp's in the D. melanogaster subgroup and that adaptive Acp protein evolution is likely more common in D. mojavensis/D. arizonae than in D. melanogaster/D. simulans. These findings are consistent with the idea that greater postcopulatory selection results in more adaptive evolution of seminal fluid proteins in the repleta group flies. Here we report another interesting evolutionary difference between the repleta group and the D. melanogaster subgroup Acp's. Acp gene duplications are present in D. melanogaster, but their high sequence divergence indicates that the fixation rate of duplicated Acp's has been low in this lineage. Here we report that D. mojavensis and D. arizonae genomes contain several very young duplicated Acp's and that these Acp's have experienced very rapid, adaptive protein divergence. We propose that rapid remating of female desert Drosophila generates selection for continuous diversification of the male Acp complement to improve male fertilization potential. Thus, mating system variation may be associated with adaptive protein divergence as well as with duplication of Acp's in Drosophila.

    Male accessory gland inflammation or infection (MAGI) is a potentially underdiagnosed complication of type 2 diabetes (DM2); specifically, we reported in a recent study that the frequency of MAGI was 43% among DM2 patients. In previous studies, we have demonstrated that diabetic autonomic neuropathy (DAN) is associated with a peculiar ultrasound characterization of the seminal vesicles (SVs) in DM2 patients. The aim of the present study was to evaluate the frequency of MAGI in two different categories of DM2 patients (i.e. patients with and without symptoms that possibly reflect DAN) and the respective ultrasound characterizations. Sixty DM2 patients with a mean (± s.e.m.) age of 42.0 ± 6.0 years (range: 34–47 years) were classified according to the presence or the absence of symptoms that could possibly reflect DAN (group A: DM2 with symptoms possibly reflecting DAN, n = 28 patients and group B: DM2 without symptoms possibly reflecting DAN, n = 32 patients). The patients in Group A exhibited a significantly higher frequency of MAGI compared with those in group B patients (P < 0.05); moreover, the Group A patients exhibited a significantly higher frequency of ultrasound signs suggestive of vesiculitis (P < 0.05). Finally, the concentrations of lymphocytes but not the concentrations of the leukocytes in the semen were significantly higher (P < 0.05) in group A compared with group B. PMID:24799635

    Tumors of the accessory parotid gland (APG) are rare, and pleomorphic adenoma (PA) is the most common benign APG tumor subtype. Myoepithelioma of the APG is much rarer than PA, and to date, only 5 cases have been sporadically reported in the English literature. We describe the clinicopathological and MRI findings of an epithelioid myoepithelioma of the APG that was treated in our hospital. The patient's only clinical symptom was a slow-growing and painless mid-cheek mass. The tumor was suspected to be PA before surgery based on the following MRI findings: (1) a well-circumscribed and lobulated contour, (2) isointensity and hyperintensity relative to the muscle on T1- and T2-weighted images (WIs), respectively, (3) good enhancement on contrast-enhanced T1-WIs, (4) peripheral hypointensity on T2-WIs, and (5) a gradual time-signal intensity curve enhancement pattern on gadolinium-enhanced dynamic MRI. The tumor was completely resected via a standard parotidectomy approach, and the postoperative pathological examination of the tumor, including immunohistochemistry, confirmed the diagnosis of epithelioid myoepithelioma. As it is hardly possible to distinguish myoepithelioma from PA and low-grade malignant tumors preoperatively, a pathological examination using frozen sections is helpful for surgical strategy-related decisions.

    Male accessory gland protein genes (Acps) evolve rapidly in the melanogaster species subgroup of Drosophila. However, conservation of Acps in more diverged lineages is poorly understood. We used comparisons of the D. melanogaster and D. pseudoobscura genome sequences, along with empirical investigation of D. pseudoobscura transcription, to assay the D. pseudoobscura genome for orthologs of 13 D. melanogaster Acps (Acp26Aa, Acp26Ab, Acp29AB, Acp32CD, Acp33A, Acp36DE, Acp53Ea, Acp62F, Acp63F, Acp70A, Acp76A, Acp95EF, and Acp98AB). We find that Acp26Aa, Acp26Ab, Acp32CD, and Acp53Ea are present at the expected microsyntenic locations of D. pseudoobscura. Acp62F and Acp70A are also present, although they are located in nonsyntenic regions. For six of the remaining seven Acps, computational and molecular biological evidence suggests they are D. melanogaster orphans. The weighted average of interspecific amino acid identity for alignable residues across the six orthologous Acps is 35.6%. Population genetic data for D. pseudoobscura Acp26Aa show that this gene has been evolving under directional selection, as it has been in D. melanogaster/D. simulans. All four D. melanogaster Acps we analyze from chromosome arm 3L are absent from the homologous D. pseudoobscura XR chromosome arm, which was autosomal before an X chromosome-autosome fusion event in the D. pseudoobscura lineage. This observation is consistent with the hypothesis that male-advantage genes on the Drosophila X chromosome are disfavored by natural selection.

    The accessory nidamental gland (ANG) of the female Hawaiian bobtail squid, Euprymna scolopes, houses a consortium of bacteria including members of the Flavobacteriales, Rhizobiales, and Verrucomicrobia but is dominated by members of the Roseobacter clade (Rhodobacterales) within the Alphaproteobacteria. These bacteria are deposited into the jelly coat of the squid’s eggs, however, the function of the ANG and its bacterial symbionts has yet to be elucidated. In order to gain insight into this consortium and its potential role in host reproduction, we cultured 12 Rhodobacterales isolates from ANGs of sexually mature female squid and sequenced their genomes with Illumina sequencing technology. For taxonomic analyses, the ribosomal proteins of 79 genomes representing both roseobacters and non-roseobacters along with a separate MLSA analysis of 33 housekeeping genes from Roseobacter organisms placed all 12 isolates from the ANG within two groups of a single Roseobacter clade. Average nucelotide identity analysis suggests the ANG isolates represent three genera (Leisingera, Ruegeria, and Tateyamaria) comprised of seven putative species groups. All but one of the isolates contains a predicted Type VI secretion system, which has been shown to be important in secreting signaling and/or effector molecules in host–microbe associations and in bacteria–bacteria interactions. All sequenced genomes also show potential for secondary metabolite production, and are predicted to be involved with the production of acyl homoserine lactones (AHLs) and/or siderophores. An AHL bioassay confirmed AHL production in three tested isolates and from whole ANG homogenates. The dominant symbiont, Leisingera sp. ANG1, showed greater viability in iron-limiting conditions compared to other roseobacters, possibly due to higher levels of siderophore production. Future comparisons will try to elucidate novel metabolic pathways of the ANG symbionts to understand their putative role in host

    Genes that influence mating and/or fertilization success may be targets for strong natural selection. If females remate frequently relative to the duration of sperm storage and rate of sperm use, sperm displacement may be an important component of male reproductive success. Although it has long been known that mutant laboratory stocks of Drosophila differ in sperm displacement, the magnitude of the naturally occurring genetic variation in this character has not been systematically quantified. Here we report the results of a screen for variation in sperm displacement among 152 lines of Drosophila melanogaster that were made homozygous for second and/or third chromosomes recovered from natural populations. Sperm displacement was assayed by scoring the progeny of cn;bw females that had been mated sequentially to cn;bw and tested males in either order. Highly significant differences were seen in both the ability to displace sperm that is resident in the female`s reproductive tract and in the ability to resist displacement by subsequent sperm. Most lines exhibited nearly complete displacement, having nearly all progeny sired by the second male, but several lines had as few as half the progeny fathered by the second male. Lines that were identified in the screen for naturally occurring variation in sperm displacement were also characterized for single-strand conformation polymorphisms (SSCP) at seven accessory gland protein (Acp) genes. Significant associations were found between particular Acp alleles at four different loci (Acp26Aa/Ab, Acp29B, Acp36DE and Acp53E) and the ability of males to resist displacement by subsequent sperm. There was no correlation between the ability to displace resident sperm and the ability to resist being displaced by subsequent sperm. This lack of correlation, and the association of Acp alleles with resisting subsequent sperm only, suggests that different mechanisms mediate the two components of sperm displacement. 36 refs., 4 figs., 7 tabs.

    We have previously demonstrated a high frequency of premature ejaculation (PE) among patients with male accessory gland infection (MAGI). The aim of this study was to evaluate the ultrasound (US) features of patients with MAGI and acquired premature ejaculation (APE) associated (MAGI-APEpos). US evaluation of 50 MAGI-APEpos patients compared to 50 patients with MAGI without PE (MAGI-PEneg) which represent the control group. The diagnosis of APE was made through the evaluation of Intravaginal ejaculation latency time (IELT) and confirmed with the questionnaire PEDT (Premature Ejaculation Diagnostic Tool). The main outcome measure was represented by the frequency of US criteria suggestive of P (prostatitis), V (vesiculitis), and E (epididymitis) in MAGI-APEpos and MAGI-PEneg patients. MAGI-APEpos patients showed a total number of US criteria significantly higher compared to MAGI-PEneg patients. MAGI-APEpos showed a higher frequency of US criteria of V and E (complicated forms of MAGI). Finally, in MAGI-APEpos group, it was found a positive relationship between the anteroposterior diameter (APD) of the caudal tract of the epididymis and the APD of the seminal vesicles, as well as between both diameters and the PEDT score. MAGI-APEpos patients have a peculiar US characterization compared to MAGI-PEneg patients. According to these results, US evaluation of the epididymal and of the prostato vesicular tract should be considered in the practical clinical approach of patients with MAGI and APE. In particular, it could be a support for a possible pathophysiological interpretation of this clinical problem in these patients. PMID:26387584

    Background Insect seminal fluid is a complex mixture of proteins, carbohydrates and lipids, produced in the male reproductive tract. This seminal fluid is transferred together with the spermatozoa during mating and induces post-mating changes in the female. Molecular characterization of seminal fluid proteins in the Mediterranean fruit fly, Ceratitis capitata, is limited, although studies suggest that some of these proteins are biologically active. Methodology/Principal Findings We report on the functional annotation of 5914 high quality expressed sequence tags (ESTs) from the testes and male accessory glands, to identify transcripts encoding putative secreted peptides that might elicit post-mating responses in females. The ESTs were assembled into 3344 contigs, of which over 33% produced no hits against the nr database, and thus may represent novel or rapidly evolving sequences. Extraction of the coding sequences resulted in a total of 3371 putative peptides. The annotated dataset is available as a hyperlinked spreadsheet. Four hundred peptides were identified with putative secretory activity, including odorant binding proteins, protease inhibitor domain-containing peptides, antigen 5 proteins, mucins, and immunity-related sequences. Quantitative RT-PCR-based analyses of a subset of putative secretory protein-encoding transcripts from accessory glands indicated changes in their abundance after one or more copulations when compared to virgin males of the same age. These changes in abundance, particularly evident after the third mating, may be related to the requirement to replenish proteins to be transferred to the female. Conclusions/Significance We have developed the first large-scale dataset for novel studies on functions and processes associated with the reproductive biology of Ceratitis capitata. The identified genes may help study genome evolution, in light of the high adaptive potential of the medfly. In addition, studies of male recovery dynamics in terms

In order to understand toxic mechanisms of lead (Pb) on the testes and the accessory glands of crabs, we investigated Pb accumulation in testes and accessory glands and the survival rate of sperms of freshwater crab, Sinopotamon henanense. The tissue damaging effects of Pb was also investigated by histopathological examination and analyses of antioxidant enzymes as well as lipid peroxidation. Crabs were exposed to different Pb concentrations (0, 3.675, 7.35, 14.7, 29.4 and 58.8 mg/L) for 3, 5 and 7 days. The results showed that Pb levels in testes and accessory glands increased significantly following Pb exposure for 5 and 7 days in almost all treated groups, and survival rate of sperm decreased with increasing Pb concentrations at 5 and 7 days. Morphological changes identified histologically were discovered in testes, including a disordered arrangement of germ cells, a decreased number of sperm in the lumina of the seminiferous tubules, extensive necrosis in the germinal layer of the seminiferous tubules, etc. At the same time, histological abnormalities were discovered in accessory glands, the wall cells were separated from the basement membrane, and wall cells were missing partly. The activities of SOD, GPx and CAT in testes showed no statistically significant changes compared to the control for 3 days, and initially increased and subsequently decreased with increasing Pb concentrations at 5 and 7 days. The antioxidant enzyme activities in accessory glands initially increased and subsequently decreased with increasing Pb concentrations and Pb exposure. This was accompanied with an increase in malondialdehyde (MDA) content in a concentration-dependent manner. These results showed that acute Pb exposure led to a reduction of survival rate of sperm and harmful effects at the cellular level of crab testes and accessory

    In honeybees, reproductive females usually mate early in their life with more than 10 males in free flight, often within 10 minutes, and then store male gametes for up to five years. Because of the extreme polyandry and mating in free flight special adaptations in males are most likely. We present here the results of an investigation of the protein content of four types of male reproductive glands from the Western honeybee (Apis mellifera) drone, namely seminal vesicles (secretion in ejaculate), as well as bulbus, cornua and mucus glands (secretions for the mating plug). Using high resolution and accuracy mass spectrometry and a combination of database searching and de novo sequencing techniques it was possible to identify 50 different proteins in total, inside all mentioned glands, except in the mucus gland. Most of the proteins are unique for a specific gland type, only one of them (H9KEY1/ATP synthase subunit O) was found in three glands, and 7 proteins were found in two types of glands. The identified proteins represent a wide variety of biological functions and can be assigned to several physiological classes, such as protection, energy generation, maintaining optimal conditions, associated mainly with vesicula seminalis; signaling, cuticle proteins, icarpin and apolipoproteins located mainly in the bulbus and cornua glands; and some other classes. Most of the discovered proteins were not found earlier during investigation of semen, seminal fluid and tissue of reproductive glands of the bee drone. Moreover, we provide here the origin of each protein. Thus, the presented data might shed light on the role of each reproductive gland.

    Adult reproductive diapause is characterized by lower behavioral activity, ceased reproduction and absence of juvenile hormone (JH). The role of JH receptor Methoprene-tolerant (Met) in female reproduction is well established; however, its function in male reproductive development and behavior is unclear. In the bean bug, Riptortus pedestris, circadian genes are essential for mediating photoperiodically-dependent growth of the male accessory glands (MAGs). The present study explores the role of circadian genes and JH receptor in male diapause in the linden bug, Pyrrhocoris apterus. These data indicate that circadian factors Clock, Cycle and Cry2 are responsible for photoperiod measurement, whereas Met and its partner protein Taiman participate in JH reception. Surprisingly, knockdown of the JH receptor neither lowered locomotor activity nor reduced mating behavior of males. These data suggest existence of a parallel, JH-independent or JH-upstream photoperiodic regulation of reproductive behavior. PMID:26826599

    A case of polymorphous low-grade adenocarcinoma of minor salivary gland is reported. This tumor was first described in two clinical case series in 1983. Before that time most of these neoplasms were diagnosed as benign salivary gland neoplasms (pleomorphic adenomas) or salivary malignant conditions (malignant pleomorphic adenomas, adenoid cystic carcinomas, papillary adenocarcinomas and adenocarcinoma not otherwise stated). This neoplasm, with few exceptions, originates in minor salivary gland tissues of the palates or buccal mucosa. It is characteristically slow to enlarge. Clinical reports show the neoplasm present for many years before diagnosis. The tumor have a variety of morphological patterns, a cytological uniformity and an infiltration into adjacent structures. The treatment is a wide local excision. Recurrences and lymph node metastases are rare.

    Induction of new proteinase activities that may process growth factors, modify cell surface receptors, cleave extracellular matrix proteins, etc. is considered fundamental in carcinogenesis. The purpose of this study was to characterize a novel proteinase activity induced in sex accessory gland cancers (about 70% in seminal vesicles) of adult male Lobund-Wistar rats by a single injection of N-nitroso-N-methylurea (NMU; 25mg/kg) followed by implanted testosterone propionate (45mg in silastic tubing every 2months) treatment for 10-14months. A 28kDa proteinase activity was detected in tumor extracts using SDS-gelatin gel zymography with incubations done without CaCl2. Its activity was stimulated 15 fold by heparin (optimal activity 1.5-3.0μg/lane) added to the tissue extract-SDS sample buffer prior to electrophoresis. No 28kDa heparin-stimulated proteinase (H-SP) was found in the dorsal, lateral and anterior (coagulating gland) prostate lobes or seminal vesicles of untreated adult rats, but there was a 26-30kDa Ca(2+)-independent proteinase activity in the ventral prostate that showed limited heparin stimulation. The 28kDa H-SP was completely inhibited by 1.0mM 4-(2-aminoethyl)benzenesulfonylfluoride (AESBF) indicating that it was a serine-type proteinase. Other types of proteinase inhibitors were without effect, including serine proteinase inhibitors benzamidine, tranexamic acid and ε-aminocaproic acid. Proteinase activities of about 28kDa were found with casein, fibrinogen or carboxymethylated transferrin as substrate, however, these activities were not stimulated by heparin. Similar levels of activities of the 28kDa H-SP were found in primary tumors and their metastases, but little/no activity was detected in serum, even from rats with large tumor volume and metastases. These data demonstrate overexpression of a heparin-stimulated 28kDa serine proteinase in the primary tumors of sex accessory gland cancers and their metastases. This proteinase either does not

    A study of the potential biological effects of veralipride was conducted in female rats. A definite stimulating action on the mammary gland was noted, but doses of 5 to 20 mg/kg/day are required to produce secretion, which is varying from one animal to another. Follicular maturation is preserved, though there is an increase in the number of corpora lutea with more marked development in some of them. Progesterone impregnation of the uterus occurs in a variable way and then only at doses of 5 + 0 20 mg/kg/day. Vaginal mucification, from a reduction in estrogen in relation to progesterone impregnation, is noted after 1 mg/kg/day (though 25 p. cent of the animals still demonstrate vaginal keratinization after 20 mg/kg/day). Finally, degranulation of the carminophile cells of the anterior pituitary gland, occurs after 5 mg/kg/day.

    Sexual conflict shapes the evolution of many behaviours and processes involved in reproduction. Nearly all evidence supporting this comes from species where the sexes are separated. However, a substantial proportion of animals and most plants are hermaphroditic, and theoretical work predicts that sexual conflict plays an important role even when the sexes are joined within one individual. This seems to have resulted in bizarre mating systems, sophisticated sperm packaging and complex reproductive morphologies. By far the best-known example of such a strategy in hermaphrodites is the shooting of so-called love-darts in land snails. All known love darts carry a gland product on their outside and enter this into the partner’s hemolymph by stabbing. Here, we show that species of the snail genus Everettia possess a syringe-like dart that serves as a real injection needle. Their dart is round in cross-section, contains numerous channels, and has perforations along its side. Histology and electron microscopy show that these holes connect to the channels inside the dart and run all the way up to the elaborate mucus glands that are attached to the dart sac. This is the first report on a love dart that is used as a syringe to directly inject the gland product into the partner’s hemolymph. Although the exact use and function of this dart remains to be demonstrated, this clearly adds to the complexity of the evolution of reproductive strategies in hermaphrodites in general. Moreover, the perforations on the outside of the love dart resemble features of other injection devices, thus uncovering common design and repeated evolution of such features in animals.

    Vampire bats are notorious for being the sole mammals that strictly feed on fresh blood for their survival. While their saliva has been historically associated with anticoagulants, only one antihemostatic (plasminogen activator) has been molecularly and functionally characterized. Here, RNAs from both principal submandibular and accessory glands of Desmodus rotundus were extracted, and ~ 200 million reads were sequenced by Illumina. The principal gland was enriched with plasminogen activators with fibrinolytic properties, members of lipocalin and secretoglobin families, which bind prohemostatic prostaglandins, and endonucleases, which cleave neutrophil-derived procoagulant NETs. Anticoagulant (tissue factor pathway inhibitor, TFPI), vasodilators (PACAP and C-natriuretic peptide), and metalloproteases (ADAMTS-1) were also abundantly expressed. Members of the TSG-6 (anti-inflammatory), antigen 5/CRISP, and CCL28-like (antimicrobial) protein families were also sequenced. Apyrases (which remove platelet agonist ADP), phosphatases (which degrade procoagulant polyphosphates), and sphingomyelinase were found at lower transcriptional levels. Accessory glands were enriched with antimicrobials (lysozyme, defensin, lactotransferrin) and protease inhibitors (TIL-domain, cystatin, Kazal). Mucins, heme-oxygenase, and IgG chains were present in both glands. Proteome analysis by nano LC-MS/MS confirmed that several transcripts are expressed in the glands. The database presented herein is accessible online at http://exon.niaid.nih.gov/transcriptome/D_rotundus/Supplemental-web.xlsx. These results reveal that bat saliva emerges as a novel source of modulators of vascular biology. PMID:23411029

    Transrectal ultrasonic-guided massage of the accessory sex glands (TUMASG) is an alternative technique for sperm collection which decreases negative animal welfare concerns of electroejaculation. However, quality of collected sperm with TUMASG is less than that collected by electroejaculation. Utilisation of TUMASG may not, however, induce strong muscular contractions, so administration of oxytocin before the procedure may improve sperm quality. Therefore, two studies were designed to determine if administration of oxytocin before TUMASG improves the procedure and quality of the collected semen. The first study was performed with anaesthetised mouflons, and the second with non-anaesthetised Gabon bucks. Time length, number of electric pulses applied and numbers of vocalizations were recorded, and sperm characteristics were analysed. The number of electrical pulses and sperm characteristics did not differ with oxytocin administration in mouflons. However, oxytocin administration decreased time length (P=0.02) and tended to decrease the number of electric pulses needed for induction of ejaculation (P=0.08) in bucks. The number of vocalizations and sperm variables did not differ when the two procedures were used. In conclusion, oxytocin administration before TUMASG shortened the procedure and tended to decrease the number of electrical pulses needed to induce ejaculation in conscious bucks, thus, decreasing welfare concerns for the animals in which TUMASG is used. Therefore, its routine inclusion in this species should be considered. PMID:27530370

    Human malaria, a major public health burden in tropical and subtropical countries, is transmitted exclusively by the bite of a female Anopheles mosquito. Malaria control strategies aimed at inducing sexual sterility in natural vector populations are an attractive alternative to the use of insecticides. However, despite their importance as disease vectors, limited information is available on the molecular mechanisms regulating fertility in Anopheles mosquitoes. In the major malaria vector, An. gambiae, the full complement of sperm and seminal fluid required for a female’s lifelong egg production is obtained from a single mating event. This single mating has important consequences for the physiology and behavior of An. gambiae females: in particular, they become refractory to further insemination, and they start laying eggs. In other insects including Drosophila, similar post-copulatory changes are induced by seminal proteins secreted by the male accessory glands and transferred to the female during mating. In this review, we analyze the current state of knowledge on the function and characterization of male seminal proteins in An. gambiae, and provide a comparative assessment of the role of these male reproductive factors in other mosquito vectors of human disease in which female post-copulatory behavior has been studied. Knowledge of the factors and mechanisms regulating fertility in An. gambiae and other vectors can help the design of novel control strategies to fight the spread of disease. PMID:22943543

    Seminal fluid is an important part of the ejaculate of internally fertilizing animals. This fluid contains substances that nourish and activate sperm for successful fertilization. Additionally, it contains components that influence female physiology to further enhance fertilization success of the sperm donor, possibly beyond the recipient's optimum. Although evidence for such substances abounds, few studies have unraveled their identities, and focus has been exclusively on separate-sex species. We present the first detailed study into the seminal fluid composition of a hermaphrodite (Lymnaea stagnalis). Eight novel peptides and proteins were identified from the seminal-fluid-producing prostate gland and tested for effects on oviposition, hatching and consumption. The gene for the protein found to suppress egg mass production, Ovipostatin, was sequenced, thereby providing the first fully-characterized seminal fluid substance in a simultaneous hermaphrodite. Thus, seminal fluid peptides and proteins have evolved and can play a crucial role in sexual selection even when the sexes are combined. PMID:20404934

    In insects, products of the male reproductive tract are essential for initiating and maintaining the female post-mating response (PMR). The PMR includes changes in egg laying, receptivity to courting males, and sperm storage. In Drosophila, previous studies have determined that the main cells of the male accessory gland produce some of the products required for these processes. However, nothing was known about the contribution of the gland's other secretory cell type, the secondary cells. In the course of investigating the late functions of the homeotic gene, Abdominal-B (Abd-B), we discovered that Abd-B is specifically expressed in the secondary cells of the Drosophila male accessory gland. Using an Abd-B BAC reporter coupled with a collection of genetic deletions, we discovered an enhancer from the iab-6 regulatory domain that is responsible for Abd-B expression in these cells and that apparently works independently from the segmentally regulated chromatin domains of the bithorax complex. Removal of this enhancer results in visible morphological defects in the secondary cells. We determined that mates of iab-6 mutant males show defects in long-term egg laying and suppression of receptivity, and that products of the secondary cells are influential during sperm competition. Many of these phenotypes seem to be caused by a defect in the storage and gradual release of sex peptide in female mates of iab-6 mutant males. We also found that Abd-B expression in the secondary cells contributes to glycosylation of at least three accessory gland proteins: ovulin (Acp26Aa), CG1656, and CG1652. Our results demonstrate that long-term post-mating changes observed in mated females are not solely induced by main cell secretions, as previously believed, but that secondary cells also play an important role in male fertility by extending the female PMR. Overall, these discoveries provide new insights into how these two cell types cooperate to produce and maintain a robust female PMR.

    The accessory sex gland (ASG) is an important component of the male reproductive system, which functions to enhance the fertility of spermatozoa during male reproduction. Certain proteins secreted by the ASG are known to bind to the spermatozoa membrane and affect its function. The ASG gene expression profile in Chinese mitten crab (Eriocheir sinensis) has not been extensively studied, and limited genetic research has been conducted on this species. The advent of high-throughput sequencing technologies enables the generation of genomic resources within a short period of time and at minimal cost. In the present study, we performed de novo transcriptome sequencing to produce a comprehensive transcript dataset for the ASG of E. sinensis using Illumina sequencing technology. This analysis yielded a total of 33,221,284 sequencing reads, including 2.6 Gb of total nucleotides. Reads were assembled into 85,913 contigs (average 218 bp), or 58,567 scaffold sequences (average 292 bp), that identified 37,955 unigenes (average 385 bp). We assembled all unigenes and compared them with the published testis transcriptome from E. sinensis. In order to identify which genes may be involved in ASG function, as it pertains to modification of spermatozoa, we compared the ASG and testis transcriptome of E. sinensis. Our analysis identified specific genes with both higher and lower tissue expression levels in the two tissues, and the functions of these genes were analyzed to elucidate their potential roles during maturation of spermatozoa. Availability of detailed transcriptome data from ASG and testis in E. sinensis can assist our understanding of the molecular mechanisms involved with spermatozoa conservation, transport, maturation and capacitation and potentially acrosome activation.

    To describe the macroscopic anatomy of the genital organs of the male pampas deer (Ozotoceros bezoarticus), organs from ten animals found dead in a captive breeding station were dissected. The unpigmented scrotum was located in the inguinal region near the body, and was covered by the thighs. In the investments of the testicles the dartos tunic was greatly developed. The cremaster muscle was located dorsocaudal to the testicle, and was divided caudally into three bundles of fibers. The right testicle was significantly heavier than the left, and there was a positive relationship between body weight and the weight of both testicles. The tail of the epididymis, ventrally located, had a caudal portion attached to the caudal extremity of the testicles by the proper ligament of the testicles, and a portion elongated free caudally located. The deferent duct was located caudomedially to the corresponding testicle. The accessory genital glands were the ampullary glands, vesicular glands, and a small pars disseminata of the prostate. The penis was fibroelastic, without sigmoid flexure, with a thick albuginea. The retractor penis muscle was very long, and ended in the distal part of the penis near the rudimentary glans. The general disposition of the male genital organs of the pampas deer were similar to that of other ruminants, with some differences, such as size and location of the testicles, the absence of the sigmoid flexure of the penis, and fewer accessory genital glands.

    Objective of the present paper is to review microbial diseases of the genital system of male small ruminants. The paper reviews the infections and the diseases by taking an organ approach within the genital system, whilst relevant health management actions are also discussed. Diseases of the genital organs of male small ruminants include orchitis, of bacterial or viral aetiology, epididymitis, primarily caused by Brucella ovis, by other bacteria as well (e.g., Actinobacillus seminis, Haemophilus somni), infections of the accessory glands, orf, other infections of the penis or prepuce and infections of the scrotum. The health management of rams/bucks include the appropriate diagnostic investigations, the relevant therapeutic approaches and, finally, the preventive measures. PMID:26209019

    In insects, the accessory gland proteins (Acps) secreted by male accessory glands (MAGs) account for the majority of seminal fluids proteins. Mixed with sperm, they are transferred to the female at mating and so impact reproduction. In this project, we identified 2,927 proteins in the MAG secretions of the oriental fruit fly Bactrocera dorsalis, an important agricultural pest worldwide, using LC-MS analysis, and all sequences containing open reading frames were analyzed using signalP. In total, 90 Acps were identified. About one third (26) of these 90 Acps had a specific functional description, while the other two thirds (64) had no functional description including dozens of new classes of proteins. Hence, several of these novel Acps were abundant in the MAG secretions, and we confirmed their MAG-specific expression by qPCR. Finally and interestingly, one of these novel proteins was functionally predicted as juvenile hormone-binding protein, suggesting the impact of Acps with reproductive events in the female. Our results will aid in the development of an experimental method to identify Acps in insects, and in turn this information with new Acps in B. dorsalis will pave the way of further exploration their function in reproduction and potential development as new insecticide targets.

    In insects, the accessory gland proteins (Acps) secreted by male accessory glands (MAGs) account for the majority of seminal fluids proteins. Mixed with sperm, they are transferred to the female at mating and so impact reproduction. In this project, we identified 2,927 proteins in the MAG secretions of the oriental fruit fly Bactrocera dorsalis, an important agricultural pest worldwide, using LC-MS analysis, and all sequences containing open reading frames were analyzed using signalP. In total, 90 Acps were identified. About one third (26) of these 90 Acps had a specific functional description, while the other two thirds (64) had no functional description including dozens of new classes of proteins. Hence, several of these novel Acps were abundant in the MAG secretions, and we confirmed their MAG-specific expression by qPCR. Finally and interestingly, one of these novel proteins was functionally predicted as juvenile hormone-binding protein, suggesting the impact of Acps with reproductive events in the female. Our results will aid in the development of an experimental method to identify Acps in insects, and in turn this information with new Acps in B. dorsalis will pave the way of further exploration their function in reproduction and potential development as new insecticide targets.

    Aedes aegypti males transfer sperm and seminal fluid proteins (Sfps), primarily produced by male accessory glands (AGs), to females during mating. When collectively injected or transplanted into females, AG tissues and/or seminal fluid homogenates have profound effects on Aedes female physiology and behavior. To identify targets and design new strategies for vector control, it is important to understand the biology of the AGs. Thus, we examined characteristics of AG secretion and development in A. aegypti, using the AG-specific seminal fluid protein, AAEL010824, as a marker. We showed that AAEL010824 is first detectable by 12h post-eclosion, and increases in amount over the first 3 days of adult life. We then showed that the amount of AAEL0010824 in the AG decreases after mating, with each successive mating depleting it further; by 5 successive matings with no time for recovery, its levels are very low. AAEL010824 levels in a depleted male are replenished by 48 h post-mating. In addition to examining the level of AAEL010824 protein, we also characterized the expression of its gene. We did this by making a transgenic mosquito line that carries an Enhanced Green Fluorescence Protein (EGFP) fused to the AAEL0010824 promoter that we defined here. We showed that AAEL010824 is expressed in the anterior cells of the accessory glands, and that its RNA levels also respond to mating. In addition to further characterizing AAEL010824 expression, our results with the EGFP fusion provide a promoter for driving AG expression. By providing this information on the biology of an important male reproductive tissue and the production of one of its seminal proteins, our results lay the foundation for future work aimed at identifying novel targets for mosquito population control.

    Seminal proteins from the Drosophila male accessory gland induce post-mating responses (PMR) in females. The PMR comprise behavioral and physiological changes that include increased egg laying, decreased receptivity to courting males, and changes in the storage and use of sperm. Many of these changes are induced by a "sex peptide" (SP) and are maintained by SP's binding to, and slow release from, sperm. The accessory gland contains two secretory cell types with distinct morphological and developmental characteristics. Products of these "main" and "secondary" cells work interdependently to induce and maintain the PMR. To identify individual genes needed for the morphology and function of secondary cells, we studied iab-6(cocu) males, whose secondary cells have abnormal morphology and fail to provide products to maintain the PMR. By RNA-seq, we identified 77 genes that are downregulated by a factor of >5× in iab-6(cocu) males. By functional assays and microscopy, we tested 20 candidate genes and found that at least 9 are required for normal storage and release of SP in mated females. Knockdown of each of these 9 genes consequently leads to a reduction in egg laying and an increase in receptivity over time, confirming a role for the secondary cells in maintaining the long-term PMR. Interestingly, only 1 of the 9 genes, CG3349, encodes a previously reported seminal fluid protein (Sfp), suggesting that secondary cells may perform essential functions beyond the production and modification of known Sfps. At least 3 of the 9 genes also regulate the size and/or abundance of secondary cell vacuoles, suggesting that the vacuoles' contents may be important for the machinery used to maintain the PMR.

    Pleomorphic adenoma is the most common tumor of the major and minor salivary glands. Rarely is it found evolving from an ectopic location of major salivary glandular tissue in the mid cheek. A healthy 56-year-old woman presented to our institution with a 20-year duration of a slowly growing right cheek soft tissue mass that was causing facial asymmetry. No significant functional or neurosensory dysfunction was appreciated. Radiologic examination showed a heterogeneous, hyperintense, well-delineated mass within the region of the right buccal fat pad. Fine-needle aspiration biopsy showed benign salivary gland elements consistent with pleomorphic adenoma. The decision was made to perform intraoral extracapsular dissection for removal. Discussion of the clinical assessment and magnetic resonance imaging evaluation with an emphasis on intraoral extracapsular dissection for definitive surgical therapy of longstanding benign salivary gland tumors is emphasized.

    The male reproductive accessory glands (RAGs) are important organs that contribute to the secretion of different substances that composed the ejaculate. Despite this important function, their composition, anatomy and function vary widely between species. Thus, the RAGs of three species of phyllostomid bats were morphologically and ultrastructurally characterized and compared in this study. The RAGs of the three analyzed species are composed of a prostate and a pair of bulbourethral glands (BG). In all species, the prostate is composed of three well-defined regions (ventral, dorsolateral and dorsal regions). The ventral region showed an atypical epithelium (undefined) with no obvious cellular limits and a holocrine PAS-positive secretion. The dorsolateral region of Carollia perspicillata and Phyllostomus discolor showed a pseudostratified cubic morphology, and that from Glossophaga soricina had a columnar morphology endowed with cytoplasmic projections and stereocilia. The dorsal region of the three analyzed species is composed of a pseudostratified columnar epithelium endowed with stereocilia; however, G. soricina also presented cytoplasmic projections in the apical portions of the secretory cells similar to those in the dorsolateral region. The BG of the three analyzed species are composed of a pseudostratified columnar epithelium including basal and PAS-positive secretory cells. In conclusion, this study morphologically and ultrastructurally characterized the RAGs of three species of phyllostomid bats, demonstrating the presence of a novel third prostatic region in species of this family. The results also showed the absence of seminal vesicles and ampullary glands, and better characterized the holocrine pattern of the prostatic ventral region, which is unique to bats.

    Although semen quality is one of the major traits that influence breeding soundness examination outcomes in bulls, field conditions occasionally do not allow for the collection of semen samples by means of an artificial vagina. The aims of the present study were to report the results of a large number of semen collections that were performed via the transrectal massage (TRM) of the accessory sexual glands of Italian yearling beef bulls and compare this semen collection method to the artificial vagina (AV) method in term of breeding soundness examination outcomes; furthermore, we determined whether the breed affected the semen characteristics. In the TRM group (n = 475), the semen samples were collected via TRM of the accessory sexual glands, and in the AV group (n = 502), the AV method was used. In the TRM group, semen samples were obtained from 81.3% of the bulls and penile protrusion was observed in 87.6% of the animals during semen collection. The sperm concentrations (920.5 ± 439.0 vs. 281.0 ± 259.8 × 10(6)/mL) and the percentages of total abnormal spermatozoa (22.8 ± 15.0 vs. 18.8 ± 12.9) were significantly higher in the AV group than those in the TRM group. The percentage of bulls that did not meet the minimum requirement for normal cells (≥70%) was 6.2% higher in the AV group than that in the TRM group (P < 0.05). Moreover, the samples collected from Chianina bulls by TRM exhibited a lower percentage of motile sperm and a higher percentage of abnormal spermatozoa when compared with the other two breeds. The major drawbacks of the TRM technique were the inability to conduct complete evaluation of the libido and mating ability of the yearling bulls, a significant reduction of the number of spermatozoa collected, and an increase in the variability of the semen characteristics due to breed. In conclusion, despite the drawbacks, TRM guarantees that semen evaluation can be conducted in cases in which the semen samples cannot be collected

    The aim of this study was to investigate possible ultrasound seminal vesicle (SV) changes in infertile patients with 'hypertrophic-congestive' (HCUF) or 'fibro-sclerotic' (FSUF) ultrasound form of male accessory gland infection (MAGI) after prolonged administration of tadalafil (TAD), a selective phosphodiesterase-5 inhibitor. Forty infertile patients with HCUF and 40 patients with FSUF and erectile dysfunction were selected and arbitrarily divided into two groups, who were prescribed TAD 5 mg daily for 3 months, the first 20 consecutive patients with HCUF (group A1) or FSUF (group A2) or placebo, the second 20 consecutive patients with HCUF (group B1) or FSUF (group B2). All patients underwent scrotal and prostate-vesicular transrectal ultrasound evaluation and semen analysis (WHO, 2010) before and after treatment. Group A1 patients showed a significant reduction in fundus/body ratio and higher pre- and post-ejaculatory body SV antero-posterior diameter difference compared with the other three groups. These patients showed also a significant increase in SV ejection fraction and a significant improvement in the total sperm count, progressive motility, seminal levels of fructose and ejaculate volume. These results suggest that infertile patients with HCUF had an improvement in SV ultrasound features suggestive of chronic inflammation after daily treatment with low doses of TAD.

    Indiscriminate use of pesticides for the eradication of pests causes tremendous changes to the environment and also to other nontarget organisms. To prevent such contamination of the environment and save nontarget species, zoopesticides are increasingly used as they are cost effective, eco-friendly, safe, and sustainable in the field of agriculture. The present study was undertaken to find out the effect of pygidial secretion (zoopesticide) on Odontopus varicornis. The insects were exposed to pygidial secretion for 24, 48, 72, and 96 hours and its sublethal concentration was found to be about 2.8% for 48 hours. When the insects were injected with sublethal concentration 2.8% for 48 hours, the study revealed certain remarkable changes in the histopathology of the male accessory reproductive glands (MARGs) such as disintegration of epithelial cell wall, swollen nucleus, vacuolization of cytoplasm, highly pycnotic and necrotic epithelium, enlargement of epithelial cells, and disorganized tissues. It is suggested that zoopesticide causes several histopathological damages in the MARGs of O. varicornis and affects the reproductive potentiality of O. varicornis. PMID:21042469

    Secretory cells of the female accessory sexual glands (AG) of P. apterus grow and produce yellow oily exocrine secretion in response to stimulation by endogenous juvenile hormone (JH) or exogenous treatments by JH analogues. The secretion determines the property of future egg shells by coating the chorion surface of the oocytes that are passing individually through the common uterus during oviposition. Diapausing females with a physiologically inhibited endocrine system or females with artificially removed hormonal sources show inactive ovaries and empty AG without the secretory products. Ovary-ectomised females with the intact neuroendocrine system develop hypertrophic AG loaded with the oily secretion. This shows that there is no direct dependence between formation of the oily secretion in AG and ovarian growth. Chemical analysis of the secretory products revealed the presence of acetylated glycerols, with the most abundant stearoyl-diacetyl-glycerol, stearoyl-acetyl-propionyl-glycerol, and the corresponding derivatives of arachidonic acid. In addition to this, the JH-activated secretory cells of AG also produced gamma- and delta-tocopherols. The possible antioxidant or antimutagenic action of these vitamin E compounds in insect reproduction has been emphasized.

    In the male reproductive system of insects, the male accessory glands and ejaculatory duct (MAG/ED) are important organs and their primary function is to enhance the fertility of spermatozoa. Proteins secreted by the MAG/ED are also known to induce post-mating changes and immunity responses in the female insect. To understand the gene expression profile in the MAG/ED of the oriental fruit fly Bactrocera dorsalis (Hendel), that is an important pest in fruits, we performed an Illumina-based deep sequencing of mRNA. This yielded 54,577,630 clean reads corresponding to 4.91Gb total nucleotides that were assembled and clustered to 30,669 unigenes (average 645bp). Among them, 20,419 unigenes were functionally annotated to known proteins/peptides in Gene Orthology, Clusters of Orthologous Groups, Kyoto Encyclopedia of Genes and Genomes pathway databases. Typically, many genes were involved in immunity and these included microbial recognition proteins and antimicrobial peptides. Subsequently, the inducible expression of these immunity-related genes was confirmed by qRT-PCR analysis when insects were challenged with immunity-inducible factors, suggesting their function in guaranteeing fertilization success. Besides, we identified some important reproductive genes such as juvenile hormone- and ecdysteroid-related genes in this de novo assembly. In conclusion, this transcriptomic sequencing of B. dorsalis MAG/ED provides insights to facilitate further functional research of reproduction, immunity and molecular evolution of reproductive proteins in this important agricultural pest.

    Infectious agents can impair various important human functions, including reproduction. Bacteria, fungi, viruses and parasites are able to interfere with the reproductive function in both sexes. Infections of male genito-urinary tract account for about 15% of the case of male infertility. Infections can affect different sites of the male reproductive tract, such as the testis, epididymis and male accessory sex glands. Spermatozoa themselves subsequently can be affected by urogenital infections at different levels of their development, maturation and transport. Among the most common microorganisms involved in sexually transmitted infections, interfering with male fertility, there are the Chlamydia trachomatis and Neisseria gonorrhoeae. Less frequently male infertility is due to non-sexually transmitted epididymo-orchitis, mostly caused by Escherichia coli. In female, the first two microorganisms are certainly involved in cervical, tubal, and peritoneal damage, while Herpes simplex cervicitis is less dangerous. The overall importance of cervical involvement is still under discussion. Tubo-peritoneal damage seems to be the foremost manner in which microorganisms interfere with human fertility. C. trachomatis is considered the most important cause of tubal lacerations and obstruction, pelvic inflammatory disease (PID) and adhesions. N. gonorrhoeae, even though its overall incidence seems to decline, is still to be considered in the same sense, while bacterial vaginosis should not be ignored, as causative agents can produce ascending infections of the female genital tract. The role of infections, particularly co-infections, as causes of the impairment of sperm quality, motility and function needs further investigation. Tropical diseases necessitate monitoring as for their diffusion or re-diffusion in the western world. PMID:18456385

    The aim of this study was to evaluate whether continuous sexual behavior could attenuate the effects of chronic stress on spermatogenesis, sexual glands, plasma testosterone and corticosterone in sexually experienced male rats. Rats were exposed to stress by immersion in cold water (ICW) daily for 20 or 50 consecutive days. Plasma testosterone and corticosterone, masculine sexual behavior, as well as the number of offspring, the epithelial area of seminiferous, prostatic and seminal glands were assessed. In stressed males, body and testicular weights decreased, male sexual behavior was disrupted, and adrenal weights increased. In males stressed for 50 days, prostate and seminal glands had lower weights compared with controls. Prostate and seminal epithelial areas also decreased in these males. Seminiferous tubules in testes from rats stressed for 20 or 50 days showed several degenerative signs, such as vacuoles in the basal epithelium, with picnotic indicia; moderate to severe exfoliation of degenerative germinal cells in the tubule lumen was also observed. In males stressed for 50 days a significant decrease in seminiferous epithelial area was observed from stages I-VIII, regardless of copulation. The litters from females that copulated with males stressed for 50 days decreased significantly. Chronic stress caused increase in plasma levels of corticosterone, which were higher in males stressed for 20 days than in males stressed for 50 days. Testosterone decreased in stressed males and it was lower in males stressed for 50 days. In stressed males allowed to copulate, body and testicular weights were similar to controls. Adrenal, seminal glands, and prostate weights, as well as epithelial areas of males stressed for 50 days allowed to copulate were also similar to controls. Corticosterone was lower than in males stressed for 50 days, but still higher than in controls. Testosterone in males stressed for 50 days and allowed to copulate was higher than in stressed

    The objective was to characterize the stress response and the seminal parameters obtained with electroejaculation (EE) or transrectal ultrasound-guided massage of the accessory sex glands (TUMASG) in two captive but nondomestic ruminants, the mouflons and the Iberian ibex under general anesthesia. In mouflons, the physiological responses (heart and respiratory rate, rectal temperature, cortisol, creatine kinase, potassium and glucose concentrations) changed similarly with both procedures. The TUMASG procedure was faster than EE in mouflons (21.7 ± 1.4 vs. 12.4 ± 1.2 minutes, P < 0.01). In ibexes, respiratory rate, cortisol and creatine kinase concentration changes were greater with EE than with TUMASG (final respiratory rate: 62.7 ± 5.5 vs. 38.1 ± 5.6 breaths/min [P < 0.05]; final cortisol: 51.4 ± 5.1 vs. 25.3 ± 5.6 ng/mL [P < 0.001]; and final creatine kinase: 300.9 ± 99.9 vs. 87.1 ± 16.9 U/L [P < 0.001]). Electroejaculation provided better results in some sperm parameters (mouflons: sperm score: 3.4 ± 0.3 vs. 2.6 ± 0.2 [P < 0.01]; total number of sperm ejaculated: 982.4 ± 299 vs. 710.0 ± 542.2 [P < 0.05]; ibexes: sperm with progressive motility: 47.7 ± 6.2 vs. 20.5 ± 8.3 [P < 0.05]). The transrectal ultrasound-guided massage of the accessory sex glands appears to be an alternative technique to collect sperm from wild ruminants, reducing the need for electrical stimuli and thus decreasing the undesired responses of EE in the more sensitive species. On the other hand, better fresh sperm may be collected with EE. However, TUMASG provides practical advantages in animal welfare, firstly in these wild species more sensible to stress management and capture myopathy.

    Genital herpes is a relatively common infection caused by herpes simplex virus (HSV) type one or two (HSV-1, HSV-2) respectively. It is acquired most commonly via sexual activity. More recently there has been an increase in infections due to HSV-1. Most new cases of genital HSV are not diagnosed due to HSV infections having short-lived signs and symptoms, or in many instances are asymptomatic. Hence many people infected with HSV are unaware that they have it. The risk of transmission to a partner is highest during outbreak periods, when there are visible lesions, although genital HSV can also be transmitted during asymptomatic periods. Use of condoms and antiviral medications assist in preventing transmission. Antiviral agents are effective in controlling clinical episodes, but do not eradicate infection, which remains latent for the life of a patient. Despite the surge in vaccine research, there is unfortunately no readily available preventative or therapeutic vaccine for HSV to date.

    Ticks are important vectors of numerous human diseases and animal diseases. Feeding stimulates spermatogenesis, mating and insemination of male factors that trigger female reproduction. The physiology of male reproduction and its regulation of female development are essentially a black box. Several transcriptomes have catalogued expression of tick genes in the salivary glands, synganglion and midgut but no comprehensive investigation has addressed male reproduction and mating. Consequently, a new global approach using transcriptomics, proteomics, and quantitative gene expression is needed to understand male reproduction and stimulation of female reproduction.This first transcriptome to the reproductive biology of fed male ticks, Dermacentor variabilis, was obtained by 454 pyrosequencing (563,093 reads, 12,804 contigs). Gene Ontology (Biological Processes level III) recognized 3,866 transcripts in 73 different categories; spermiogenesis; spermatogenesis; peptidases, lipases and hydrolases; oxidative and environmental stress; immune defense; and protein binding. Reproduction-associated genes included serine/threonine kinase, metalloendoproteinases, ferritins, serine proteases, trypsin, cysteine proteases, serpins, a cystatin, GPCR and others. qRT-PCR showed significant upregulation from unfed versus fed adult male reproductive organs of zinc metalloprotease, astacin metalloprotease and serine protease, enzymes important in spermiogenesis and mating activity in insects, as well as a GPCR with the greatest similarity to a SIFamide receptor known to be important in regulating courtship behavior in Drosophila. Proteomics on these organs and the spermatophore by tryptic digestion/Liquid chromatography/Mass spectrometry/Mass spectrometry (LC/MS/MS) demonstrated expression of many of the same messages found by 454 sequencing, supporting their identification, and revealed differences in protein distribution in the reproductive system versus the spermatophore. We found Ef

    To study the mechanism by which testosterone restores the sexual potency of castrated cynomolgus monkeys, two males (body weights 5.2 and 5.3 kg) were castrated and, 3 days later, injected with 3 mCi (/sup 3/H)testosterone ((/sup 3/H)T) as an intravenous bolus. After 30 min, males were killed and brains and samples of other tissues were rapidly removed and placed on ice. Samples were dissected from the right halves of the brain and homogenized. Purified cell nuclei were prepared and ether extracts were analyzed by reverse-phase HPCL. Generally, unchanged (/sup 3/H)T was the major form of radioactivity in brain and pituitary gland, but in cell nuclei from hypothalamus, preoptic area and amygdala, a large proportion (34 - 61%) was in the form of (/sup 3/H)estradiol ((/sup 4/H)E/sub 2/). Little or no (/sup 3/H)dihydrotestosterone ((/sup 3/H)DHT) was detected in cell nuclei from any brain region or from pituitary gland. However, (/sup 3/H)DHT was the major form (61 - 95%) of radioactivity in cell nuclei from glans penis, prostrate and seminal vesicles. In autoradiograms of the left halves of the same brains, the percentage of cells that accumulated radioactivity in their nuclei was high in specific regions of the hypothalamus, preoptic areas and amygdala. The authors conclude that the peripheral actions of T are mediated via DHT, but its central actions are dependent on unchanged T or on E/sub 2/ formed locally by aromatization.

    Wandering through the exhibit hall yesterday, I noticed that if you look at the laser companies and if you look at the accessory companies, there are pretty much the same number of accessory booths as well as the laser companies. There was one difference. Laser company booths are all sexy looking, very flashy, big booths. Whereas if you look at the accessories booths, they were small, not so prominent.

    Despite scant evidence supporting the use of disposable accessories, these devices have been widely disseminated. Manufacturers and governmental regulators, the most devout proponents of one-time use accessories, have framed the issue in economic terms-parsimonious practitioners reusing disposable accessories at the risk of cross-contamination, mechanical failure and product liability. This simplistic view represents revisionist history and ignores the long tradition of reusing these devices. This article reviews the numerous studies that support the safe and cost effective reuse of disposable and reusable accessories.

  9. Semen polymorphonuclear neutrophil leukocyte elastase as a diagnostic and prognostic marker of genital tract inflammation--a review.

    Elastase is a protease released by polymorphonuclear neutrophils (PMN) during the inflammatory process. Since 1987, seminal elastase-inhibitor complex (Ela/alpha1-PI) has been proposed as a marker of male silent genital tract inflammation. Measured by immunoassay in seminal plasma, Ela/alpha1-PI at a cut-off level of > or = 230 microg/l, is useful in the detection of genital tract inflammation. The prevalence of increased seminal Ela/alpha1-PI in infertile men is significantly higher than that observed in fertile men. The Ela/alpha1-PI level is positively correlated with other seminal fluid markers of male genital tract inflammation: reduced semen volume, citric acid, fructose, and increased albumin, complement component C3, caeruloplasmin, immunoglobulins IgG and IgA, and cytokines interleukins-8 and -6. A higher seminal Ela/alpha1-PI level is significantly associated with tubal damage in female partners. After antibiotic therapy, a decrease of Ela/alpha1-PI level is observed. The presence of tubal damage in the partner may negatively affect the response to antibiotic treatment. A higher seminal Ela/alpha1-PI is associated with lower percentage of sperm with single-stranded deoxyribonucleic acid (DNA) and better fertilization rate in in vitro fertilization. Besides infertility, the determination of Ela/alpha1-PI is useful to confirm the presence of prostate and other male accessory gland bacterial inflammation. Screening for PMN Ela/alpha1-PI is easy to perform and reproducible and is a reliable quantitative test for diagnosis and prognosis of silent genital tract inflammation of couples. Moreover, sequential determinations allow the follow-up of inflammation during and after therapy.

    In this article, we present a review of the literature, and we focus on 2 particular cases of cancer of the salivary glands accessory in pediatric patients The accessory parotid is the site of congenital and acquired lesions. In adults, the acquired lesions are often neoplastic and are usually similar to those seen in the main parotid gland. The disorders in children are less well defined, as only a few cases have been reported.The accessory parotid gland, or accessory parotid, is a nodule of normal salivary tissue separated from the main parotid gland, located on the masseter muscle, to which it is bound by an extension of the masseteric fascia and connected to the Stensen duct at that level. In contrast to the extensive literature on acquired lesions of the accessory parotid in adults, very few cases of malignant or benign lesions of the accessory parotid in children could be found in the literature. A review of several articles reporting lesions of the accessory parotid in adult patients, reporting 3 or more cases each for a total of 71 patients, showed 24 malignant neoplasms, 39 benign neoplasms, and 8 nonneoplastic lesions. Lesions of the accessory parotid are quite rare in children but should be considered when facing mass located in the cheek.

    Sexually transmitted pathogens are associated with a wide range of anomalies and diseases, including recurrent genital herpes, urethritis, syphilis, prostitis, genital ulcers, perihepatitis, unexplained infertility, infant prematurity, low birth weight, and neonatal death or malformations. Prompt diagnosis of sexually transmitted diseases (STDs) is essential to ensure appropriate specific treatment and to reduce complications. Extensive studies on the etiology of male infertility include poorly treated infections such as STDs, epididymitis, complications associated with mumps, delayed treatment of undescended testes, repair of inguinal hernia, varicocele, endocrine disorders, anomalies of the reproductive tract and male accessory organs, trauma, surgery, heat-cold injury, and active-passive immunization.

    To evaluate the clinical impression that young girls are given little or confusing information about their genitals, a sample of 117 mothers with 1- to 4-year-old children were asked which words for genitals, if any, they used with their children. The ethnically and socioeconomically heterogeneous sample was composed of 63 girls and 54 boys, with the average ages of 26 and 29 months, respectively. Neither boys nor girls were likely to be given a standard anatomical genital term, although many children received colorful colloquial expressions. However, girls were less likely than boys to receive a term for their genitals. Receiving names for genitals was related to certain family circumstances, such as higher parental education, exposure to adult male nudity, having a sibling of the opposite sex, and cosleeping. Pediatric health professionals have the opportunity to contribute to early sex education by conveying accurate information regarding genital terms in the course of routine physical examinations.

    Accessory fissures of the lung are commonly observed in lung specimens, but are often unappreciated or misinterpreted in radiographs and computer tomographic (CT) scans. They usually occur at the boundaries between bronchopulmonary segments. Most common are the inferior accessory fissure, which demarcates the medial basal segment; the superior accessory fissure, which demarcates the superior segment; and the left minor fissure, which demarcates the lingula. This essay will illustrate the findings of the common accessory fissures both on plain radiographs and on CT scans.

    Noninfectious genital ulcers are much more common than ulcers arising from infections. Still, it is important to take a thorough history of sexual activity and a sexual abuse screen. A physical exam should include skin, oral mucosa, nails, hair, vulva, and vaginal mucosa if needed. The differential diagnosis of noninfectious genital ulcers includes: lipschütz ulcers, complex aphthosis, Behçet's syndrome, vulvar metastatic Crohn's disease, hidradenitis suppurativa, pyoderma gangrenosum, pressure ulcers, and malignancies. It is important to come to the correct diagnosis to avoid undue testing, stress, and anxiety in patients experiencing genital ulcerations.

    2006-09-01

    The subscapular artery arises from the third part of the axillary artery and gives off the circumflex scapular and the thoracodorsal arteries. Although anatomical variations of the axillary artery are very common, the existence of a unilateral accessory thoracodorsal artery has been described in the literature only once. There are no reports of bilateral accessory thoracodorsal artery, in the literature. In the present study, a bilateral accessory thoracodorsal artery, originating on either side of the third part of the axillary artery, is described in a 68-year-old female cadaver. All the other branches of the axillary artery had a typical origin, course, distribution and termination. This extremely rare anatomical variation apart from the anatomical importance also has clinical significance for surgeons in this area. Especially, during the dissection or mobilization of the latissimus dorsi that is partly used for coverage problems in many regions of the body and also in dynamic cardiomyoplasty, any iatrogenic injury of this accessory artery may result in ischemia and functional loss of the graft.

    1996-01-01

    Accessory nerve injury produces considerable disability. The nerve is most frequently damaged as a complication of radical neck dissection, cervical lymph node biopsy and other surgical procedures. The problem is frequently compounded by a failure to recognise the error immediately after surgery when surgical repair has the greatest chance of success. We present cases which outline the risk of accessory nerve injury, the spectrum of clinical presentations and the problems produced by a failure to recognise the deficit. Regional anatomy, consequences of nerve damage and management options are discussed. Diagnostic biopsy of neck nodes should not be undertaken as a primary investigation and, when indicated, surgery in this region should be performed by suitably trained staff under well-defined conditions. Awareness of iatrogenic injury and its consequences would avoid delays in diagnosis and treatment. Images Figure 2 PMID:8678450

    Mesenchymal neoplasms of the vulvovaginal and inguinoscrotal regions are among the most diagnostically challenging specimens in the pathology laboratory owing largely to their unique intersection between general soft tissue tumors and relatively genital-specific mesenchymal tumors. Genital stromal tumors are a unique subset of soft tissue tumors encountered at this location, and this group includes fibroepithelial stromal polyp, superficial (cervicovaginal) myofibroblastoma, cellular angiofibroma, mammary-type myofibroblastoma, angiomyofibroblastoma and aggressive angiomyxoma. Aside from the striking morphologic and immunophenotypic similarity that is seen with these entities, there is evidence that a subset of genital stromal tumors may be linked genetically. This review will focus on simplifying this group of tumors and provide the pathologist or dermatopathologist with practical management information. Smooth muscle tumors of the external genitalia will also be discussed.

    Recent intervention of nonspecific genital ulcers has added refreshing dimensions to genital ulcer disease. It was considered pertinent to dwell on diverse clinical presentation and diagnostic strategies. It seems to possess spectrum. It includes infective causes, Epstein Bar Virus, tuberculosis, Leishmaniasis, HIV/AIDS related ulcers and amoebiasis. Noninfective causes are immunobullous disorders, aphthosis, Behcet's disease (BD), inflammatory bowel disease, lichen planus and lichen sclerosis et atrophicus, drug reactions, premalignant and malignant conditions, pyoderma gangrenosum, and hidradenitis suppurativa. The diagnostic features and treatment option of each disorder are succinctly outlined for ready reference.

    2011-12-01

    The Rhabdoviridae is one of the most ecologically diverse families of RNA viruses with members infecting a wide range of organisms including placental mammals, marsupials, birds, reptiles, fish, insects and plants. The availability of complete nucleotide sequences for an increasing number of rhabdoviruses has revealed that their ecological diversity is reflected in the diversity and complexity of their genomes. The five canonical rhabdovirus structural protein genes (N, P, M, G and L) that are shared by all rhabdoviruses are overprinted, overlapped and interspersed with a multitude of novel and diverse accessory genes. Although not essential for replication in cell culture, several of these genes have been shown to have roles associated with pathogenesis and apoptosis in animals, and cell-to-cell movement in plants. Others appear to be secreted or have the characteristics of membrane-anchored glycoproteins or viroporins. However, most encode proteins of unknown function that are unrelated to any other known proteins. Understanding the roles of these accessory genes and the strategies by which rhabdoviruses use them to engage, divert and re-direct cellular processes will not only present opportunities to develop new anti-viral therapies but may also reveal aspects of cellar function that have broader significance in biology, agriculture and medicine.

    1993-08-21

    Female genital mutilation, also misleadingly known as female circumcision, is usually performed on girls ranging in from 1 week to puberty. Immediate physical complications include severe pain, shock, infection, bleeding, acute urinary infection, tetanus, and death. Longterm problems include chronic pain, difficulties with micturition and menstruation, pelvic infection leading to infertility, and prolonged and obstructed labor during childbirth. An estimated 80 million girls and women have undergone female genital mutilation. In Britain alone an estimated 10,000 girls are currently at risk. Religious, cultural, medical, and moral grounds rationalize the custom which is practiced primarily in sub-Saharan Africa, the Arab world, Malaysia, Indonesia, and among migrant populations in Western countries. According to WHO it is correlated with poverty, illiteracy, and the low status of women. Women who escape mutilation are not sought in marriage. WHO, the UN Population Fund, the UN Children's Fund, the International Planned Parenthood Federation, and the UN Convention on the Rights of the Child have issued declarations on the eradication of female genital mutilation. In Britain, local authorities have intervened to prevent parents from mutilating their daughters. In 1984, the Inter-African Committee Against Harmful Traditional Practices Affecting Women and Children was established to work toward eliminating female genital mutilation and other damaging customs. National committees in 26 African countries coordinate projects run by local people using theater, dance, music, and storytelling for communication. In Australia, Canada, Europe, and the US women have organized to prevent the practice among vulnerable migrants and refugees. PMID:8400925

  12. Macrophages: important accessory cells for reproductive function.

    PubMed

    Cohen, P E; Nishimura, K; Zhu, L; Pollard, J W

    1999-11-01

    Macrophages are found throughout reproductive tissues. To determine their role(s), we have studied mice homozygous for a null mutation (Csfm(op)) in the gene encoding the major macrophage growth factor, colony-stimulating factor-1 (CSF-1). Both male and female Csfm(op)/Csfm(op) mice have fertility defects. Males have low sperm number and libido as a consequence of dramatically reduced circulating testosterone. Females have extended estrous cycles and poor ovulation rates. CSF-1 is the principal growth factor regulating macrophage populations in the testis, male accessory glands, ovary, and uterus. However, analyses of CSF-1 nullizygous mice suggest that the primary reproductive defect is in the development of feedback regulation of the hypothalamic-pituitary axis. Although not correlating with deficiencies of microglia populations, electrophysiological investigations indicate an impairment of neuronal responses. This suggests that microglia, under the influence of CSF-1, act to organize neuronal connectivity during development and that the absence of this function results in a perturbation of the hypothalamic-pituitary-gonadal axis. Macrophages also appear to have functions in the differentiated tissues of the reproductive system, including having a positive influence on steroidogenic cells. These data suggest that macrophages, through their trophic functions, can be considered as essential accessory cells for normal reproductive functioning.

    2016-01-01

    Persistent genital arousal disorder (PGAD) is a phenomenon, in which afflicted women experience spontaneous genital arousal, unresolved by orgasms and triggered by sexual or nonsexual stimuli, eliciting stress. The current case is a 40-year-old female who experienced such orgasms for about a month. Physical examination, investigations, and psychological testing were noncontributory. Carbamazepine (600 mg) was discontinued due to a lack of response. She improved significantly with supportive therapy. Various neuropsychological conditions, pelvic pathology, medications, etc., have been associated with this disorder. Pharmacologic strategies have included the use of antidepressants, antipsychotics, mood stabilizers, and analgesics. Validation, psycho-education, identifying triggers, distraction techniques, and pelvic massage have been tried. Living with PGAD is very demanding. There is a lack of understanding of the problem, shame, and hesitation to seek help. The syndrome has been recently described, and understanding is still evolving. PMID:27570347

    PubMed

    Rudoni, Caroline; Dennis, Heather

    Usage and opinion of accessory products in stoma care vary enormously. The aim of this study was to identify what constitutes an accessory product and to find out whether there is any standardization regarding their recommendation. Views of both patients and stoma nurses were examined. Patients identify accessory products as being necessary both physically and psychologically in improving their quality of life. While stoma nurses identify that the psychological effects of having a stoma should never be underestimated, there is still concern regarding the cost of recommending these products and their clinical necessity. It would appear that clinical necessity is based on nurses' opinions and is not always evidence or research based. Since accessory products have been shown to be essential to many patients with a stoma, should stoma nurses be more empathetic when considering their recommendation?

    2015-01-01

    Context and Objective: Accessory pancreatic duct (APD) designed to reduce the pressure of major pancreatic duct by forming a secondary drainage channel. Few studies have mentioned the variant types of accessory ducts and their mode of formation, some of these have a clear clinical significance. Present study is aimed to evaluate the possible variations in the APD and its terminations. Materials and Methods: Forty formalin fixed adult human pancreas with duodenum in situ specimens were studied by injecting 1% aqueous eosin, followed by piece meal dissection of the head of the pancreas from posterior surface. Formation, tributaries, relations, and the termination of the accessory pancreatic duct were noted and photographed. Results: Accessory ducts revealed 50% belonged to long type, 22.5% were of short and ansa pancreatica type each, and embryonic type of duct pattern was seen in 5% specimens. 75% of long type ducts showed positive patency with eosin dye, followed by ansa type (44.4%), and least patency was found in short type (22.2%). With regard to the patency of the accessory pancreatic ducts towards their termination, we found 52.5% of the accessory ducts and 5% of the embryonic type pancreatic ducts were patent and in 42.5% of the specimen the ducts were obliterated. In 85% of specimens the minor duodenal papillae was anterosuperior to the major papilla and superior to the major papillae in 10% of the cases, and in 5% minor papillae was absent. The average distance between the two papillae was 2.35 cm. Conclusion: The knowledge of the complex anatomical relations of the gland with its duct, duodenum and bile ducts are essential for the surgeons and sinologists to plan and perform both the diagnostic as well as therapeutic procedures effectively.

    The findings in a study of the general circulation of the suprarenal glands in 25 cases, and particularly of the left glands in 50 cases, are presented. The vessels arose from three pedicles: superior, middle and inferior. The inferior pedicle was the most irregular, with a frequent contribution from the gonadal artery to the inferior part of the gland; this artery should not be regarded as merely an accessory vessel. On the left side an inconstant posterior pedicle, separate from the others, was found in 26% of cases. Two forms of gonadal artery supplying the gland (8%) are described, an upper origin type at the renal artery level and an aberrant type.

    With mandates and regulatory policies to meet both the California Air Resources Board (CARB) and the Partnership for a New Generation of Vehicles (PNGV), designing vehicles of the future will become a difficult task. As we look into the use of electric and hybrid vehicles, reduction of the required power demand by influential automobile components is necessary in order to obtain performance and range goals. Among those automobile components are accessories. Accessories have a profound impact on the range and mileage of future vehicles with limited amounts of energy or without power generating capabilities such as conventional vehicles. Careful assessment of major power consuming accessories helps us focus on those that need improvement and contributes to attainment of mileage and range goals for electric and hybrid vehicles.

    PubMed

    Petersen, B T

    2000-04-01

    Despite the prevailing emphasis on falling reimbursements and cost containment, the use of disposable endoscopic accessories has grown tremendously. They offer simplicity of use, certain sterility, and reduced labor costs in exchange for higher purchase costs per procedure and the burden of waste disposal. Disposable accessories provide greater variety, complexity, and utility. They carry a cost burden that may be acceptable when the devices are difficult to reprocess, when they incorporate features that justify the added cost, or when their unit cost approaches purchase plus reprocessing costs for reusable alternatives, such as for biopsy forceps. Units with small volumes may prefer the ease of disposable accessories independent of relative cost issues, while large high-volume units may need to evaluate cost data more carefully to maintain sustainable practices.

    Recurrent salivary gland malignancies present difficult therapeutic decisions and poor prognosis in many instances, and treatment becomes of a palliative nature only. As many of the salivary gland malignancies we see are of the recurrent type, the following study was done to determine the efficacy of a vigorous attempt at retreatment. During the period January 1, 1960, through December 31, 1984, 352 patients with major and minor salivary gland tumors were evaluated at our institution. There were 149 benign lesions and 203 patients with malignant tumors. Of these, 99 patients had recurrent and metastatic tumors that had been treated initially elsewhere. Thirty-three of these patients were able to be treated with curative intent: surgery, 21; surgery plus radiation, 9; radiation therapy alone, 2; and radiation plus chemotherapy, 1. The 5 year survival with no evidence of disease was achieved in three patients with surgery alone and two patients with surgery plus radiation therapy. The group of five patients was comprised of two patients with adenoid cystic carcinomas of the parotid, one with intermediate grade mucoepidermoid carcinoma of the parotid, one, sebaceous cell carcinoma of the parotid, and one, adenoid cystic carcinoma of an accessory salivary gland. The results of this study serve to re-emphasize the relative poor yield of attempts at retreatment of loco-regional recurrence of salivary gland tumors.

    Acute genital ulcers, also known as acute vulvar ulcers, ulcus vulvae acutum or Lipschütz ulcers, refer to an ulceration of the vulva or lower vagina of non-venereal origin that usually presents in young women, predominantly virgins. Although its incidence is unknown, it seems a rare entity, with few cases reported in the literature. Their aetiology and pathogenesis are still unknown. The disease is characterised by an acute onset of flu-like symptoms with single or multiple painful ulcers on the vulva. Diagnosis is mainly clinical, after exclusion of other causes of vulvar ulcers. The treatment is mainly symptomatic, with spontaneous resolution in 2 weeks and without recurrences in most cases. We present a case report of a 13-year-old girl with two episodes of acute ulcers that fit the clinical criteria for Lipschütz ulcers. PMID:24473429

    Male genital lichen sclerosus (MGLSc) is a chronic inflammatory skin disease responsible for male sexual dyspareunia and urological morbidity. An afeared complication is squamous cell carcinoma (SCC) of the penis. The precise etiopathogenesis of MGLSc remains controversial although genetic, autoimmune and infective (such as human papillomavirus (HPV) hepatitis C (HCV), Epstein-Barr virus (EBV) and Borrelia) factors have been implicated: Consideration of all the evidence suggests that chronic exposure of susceptible epithelium to urinary occlusion by the foreskin seems the most likely pathomechanism. The mainstay of treatment is topical ultrapotent corticosteroid therapy. Surgery is indicated for cases unresponsive to topical corticosteroid therapy, phimosis, meatal stenosis, urethral stricture, carcinoma in situ (CIS) and squamous cell carcinoma. PMID:25814697

    The course of experimental chlamydial infection of the male genital tract was studied. Inoculation of the Chlamydia psittaci agent of guinea pig inclusion conjunctivitis (GPIC agent) into the vas deferens of rats resulted in chlamydial infection of the epididymis, testis and the prostate gland. The inflammatory response was most prominent at 14 days after infection. Chlamydiae were recovered from the epididymides and the prostate glands for up to 90 and 60 days post inoculation, respectively. Histopathological changes associated with chlamydial infection of the epididymis or prostate gland were characterized by intratubular and interstitial purulent inflammation. Chlamydia-specific IgM- and IgG-antibodies were found in sera of nearly all infected animals. Results of this study indicate that this animal model may be useful to study the pathogenesis, immune responses and sequelae of chlamydial infections of the male genital tract.

    Obstetric complications may result from burn scarring in the genital area. Women in developing countries typically squat around cooking fires, and burns are common. This recent case in Nepal describes obstructed labor in a young woman whose genital area had extensive scarring from a cooking fire injury. Proper antenatal assessment by health care providers can reduce the risk to mothers and infants of the consequences of a birth canal damaged or obstructed by burn scarring.

  10. Melanocortin receptor accessory proteins in adrenal disease and obesity

    Jackson, David S.; Ramachandrappa, Shwetha; Clark, Adrian J.; Chan, Li F.

    2015-01-01

    Melanocortin receptor accessory proteins (MRAPs) are regulators of the melanocortin receptor family. MRAP is an essential accessory factor for the functional expression of the MC2R/ACTH receptor. The importance of MRAP in adrenal gland physiology is demonstrated by the clinical condition familial glucocorticoid deficiency type 2. The role of its paralog melanocortin-2-receptor accessory protein 2 (MRAP2), which is predominantly expressed in the hypothalamus including the paraventricular nucleus, has recently been linked to mammalian obesity. Whole body deletion and targeted brain specific deletion of the Mrap2 gene result in severe obesity in mice. Interestingly, Mrap2 complete knockout (KO) mice have increased body weight without detectable changes to food intake or energy expenditure. Rare heterozygous variants of MRAP2 have been found in humans with severe, early-onset obesity. In vitro data have shown that Mrap2 interaction with the melanocortin-4-receptor (Mc4r) affects receptor signaling. However, the mechanism by which Mrap2 regulates body weight in vivo is not fully understood and differences between the phenotypes of Mrap2 and Mc4r KO mice may point toward Mc4r independent mechanisms.

  11. Male genital trauma

    1988-07-01

    We have attempted to discuss genital trauma in relatively broad terms. In most cases, patients present with relatively minimal trauma. However, because of the complexity of the structures involved, minimal trauma can lead to significant disability later on. The process of erection requires correct functioning of the arterial, neurologic, and venous systems coupled with intact erectile bodies. The penis is composed of structures that are compliant and distensible to the limits of their compliance. These structures therefore tumesce in equal proportion to each other, allowing for straight erection. Relatively minimal trauma can upset this balance of elasticity, leading to disabling chordee. Likewise, relatively minimal injuries to the vascular erectile structures can lead to significantly disabling spongiofibrosis. The urethra is a conduit of paramount importance. Whereas the development of stricture is generally related to the nature of the trauma, the extent of stricture and of attendant complications is clearly a function of the immediate management. Overzealous debridement can greatly complicate subsequent reconstruction. A delicate balance between aggressive initial management and maximal preservation of viable structures must be achieved. 38 references.

    The daily exposure of newly born female mice to the urine of lactating mice with a small ano-genital distance accelerated the onset of first oestrus while the urine from donors with a large ano-genital distance was without effect in advancing puberty. The rate of growth of the mice exposed to the urine of lactating mothers was greater than that of a control sample but it was only those mice exposed to the urine of lactating females with a small ano-genital distance which continued to grow, after the cessation of treatment at 21 days of age, at a faster rate. There was no difference in the mass of the uterus when the mice were killed when adult but there were significant age-dependent differences in the mass of the ovaries and adrenal glands. The mice exposed to the urine from lactating mothers (with both large and small ano-genital indices) had smaller ovaries than the control mice while the adrenal glands of mice exposed to the urine of lactating mothers with a large ano-genital index were of greater mass than those of the control mice and mice exposed to mothers with a small ano-genital distance. Exposure to the urine of lactating mothers had no effect on the subsequent activity of the mice when tested in an automated activity recorder. The results confirm that urine from lactating mothers accelerates the onset of puberty and suggests that the effects are restricted to the urine from mothers with a small ano-genital index.

    Polysplenism and accessory spleen are congenital, usually asymptomatic anomalies. A rare case of polysplenism with ectopic spleen in pelvis of a 67-year-old, Caucasian female is reported here. A transvaginal ultrasound found a soft well-defined homogeneous and vascularized mass in the left pelvis. Patient underwent MRI evaluation and contrast-CT abdominal scan: images with parenchymal aspect, similar to spleen were obtained. Abdominal scintigraphy with 99mTc-albumin nanocolloid was performed and pelvic region was studied with planar scans and SPECT. The results showed the presence of an uptake area of the radiopharmaceutical in the pelvis, while the spleen was normally visualized. These findings confirmed the presence of an accessory spleen with an artery originated from the aorta and a vein that joined with the superior mesenteric vein. To our knowledge, in the literature, there is just only one case of a true ectopic, locally vascularized spleen in the pelvis.

    The human tear film is a 3-layered coating of the surface of the eye and a loss, or reduction, in any layer of this film may result in a syndrome of blurry vision and burning pain of the eyes known as dry eye. The lacrimal gland and accessory glands provide multiple components to the tear film, most notably the aqueous. Dysfunction of these glands results in the loss of aqueous and other products required in ocular surface maintenance and health resulting in dry eye and the potential for significant surface pathology. In this paper, we have reviewed products of the lacrimal gland, diseases known to affect the gland, and historical and emerging dry eye therapies targeting lacrimal gland dysfunction. PMID:27042343

    The most common infectious causes of genital ulcers are herpes simplex virus and syphilis. However, mixed infections can occur and genital ulcer may increase the risk of acquiring human immunodeficiency virus. Although the history and physical examination can narrow the differential diagnosis, there is a need for initial routine laboratory testing for the most common pathogens that includes: for syphilis: serologic screening and dark field examination of the lesion; for herpes simplex virus: serology, vial culture and/or polymerase chain reaction. Human immunodeficiency testing is mandatory. Recently, some clinical laboratories adapted the reverse screening algorithm for syphilis (initial treponemal test, and, if positive, followed by non-treponemal test) that may potentially lead to overtreatment. Early and prompt therapy may decrease the risk of transmission of the infectious agent to others. This article reviews the infectious pathogens causing genital ulcers, their unique clinical manifestation, diagnosis and treatment.

    The practice of female genital mutilation (we will use the latest definition adopted by WHO/UNFP: female genital mutilation/cutting or FGM/C) is still widespread in 28 African countries. The World Health Organisation (WHO) estimates that more than two million females undergo some form of genital mutilation every year. Its negative health impact and its ethical and human rights aspects have been discussed and attempts to eliminate it have been the objectives of several meetings promoted by national and international organisations thanks to an increased awareness related to FGM/C in those countries practicing it and also, maybe due to the number of Africans migrating to industrialized countries. We review the present situation in Djibouti, a small country in the Horn of Africa, where 98 % of the female population has suffered different forms of FGM/C. PMID:23515242

    This Cooperative Research and Development Agreement (CRADA) began December 8, 2000 and ended September 30, 2009. The total funding provided by the Participant (General Motors Advanced Technology Vehicles [GM]) during the course of the CRADA totaled $1.2M enabling the Contractor (UT-Battelle, LLC [Oak Ridge National Laboratory, a.k.a. ORNL]) to contribute significantly to the joint project. The initial task was to work with GM on the feasibility of developing their conceptual approach of modifying major components of the existing traction inverter/drive to develop low cost, robust, accessory power. Two alternate methods for implementation were suggested by ORNL and both were proven successful through simulations and then extensive testing of prototypes designed and fabricated during the project. This validated the GM overall concept. Moreover, three joint U.S. patents were issued and subsequently licensed by GM. After successfully fulfilling the initial objective, the direction and duration of the CRADA was modified and GM provided funding for two additional tasks. The first new task was to provide the basic development for implementing a cascaded inverter technology into hybrid vehicles (including plug-in hybrid, fuel cell, and electric). The second new task was to continue the basic development for implementing inverter and converter topologies and new technology assessments for hybrid vehicle applications. Additionally, this task was to address the use of high temperature components in drive systems. Under this CRADA, ORNL conducted further research based on GM’s idea of using the motor magnetic core and windings to produce bidirectional accessory power supply that is nongalvanically coupled to the terminals of the high voltage dc-link battery of hybrid vehicles. In order not to interfere with the motor’s torque, ORNL suggested to use the zero-sequence, highfrequency harmonics carried by the main fundamental motor current for producing the accessory power

    The choice of optimum mechanical accessories for mobile teleoperators involves matching the criteria for emergency response with the available technology. This paper presents a general background to teleoperations, a potpourri of the manipulator systems available, and an argument for force reflecting manipulation. The theme presented is that the accomplishment of humanlike endeavors in hostile environments will be most successful when man model capabilities are utilized. The application of recent electronic technology to manipulator development has made new tools available to be applied to emergency response activities. The development activities described are products of the Consolidated Fuel Reprocessing Program at the Oak Ridge National Laboratory. 13 refs., 7 figs.

    Introduction: Surgery for bladder exstrophy has been evolving over the last four to five decades. Because survival has become almost universal, the focus has changed in the exstrophy-epispadias complex to improving quality of life. The most prevalent problem in the long-term function of exstrophy patients is the sexual activity of the adolescent and adult males. The penis in exstrophy patients appears short because of marked congenital deficiency of anterior corporal tissue. Many patients approach for genital reconstruction to improve cosmesis as well as to correct chordee. We report our series of male patients seeking genital reconstruction following exstrophy repair in the past. Materials and Methods: Fourteen adolescent/adult male patients attended urology services during the period January 2000-December 2009 seeking genital reconstruction following exstrophy repair in the past. Results: Three patients underwent epispadias repair, four patients had chordee correction with cosmetic excision of skin tags and seven patients underwent chordee correction with penile lengthening. All patients reported satisfaction in the answered questionnaire. Patients undergoing penile lengthening by partial corporal dissection achieved a mean increase in length of 1.614 ± 0.279 cm dorsally and 1.543 ± 0.230 cm ventrally. The satisfactory rate assessed by the Short Form-36 (SF-36) showed that irrespective of the different genital reconstructive procedures done, the patients were satisfied with cosmetic and functional outcome. Conclusions: Surgical procedures have transformed the management in these patients with bladder exstrophy. Bladders can be safely placed within the pelvis, with most patients achieving urinary continence and cosmetically acceptable external genitalia. Genital reconstruction in the form of correction of chordee, excision of ugly skin tags and lengthening of penis can be performed to give the patients a satisfactory cosmetic and functional system.

  2. The pineal gland from development to function.

    PubMed

    Sapède, Dora; Cau, Elise

    2013-01-01

    The pineal gland is a small neuroendocrine organ whose main and most conserved function is the nighttime secretion of melatonin. In lower vertebrates, the pineal gland is directly photosensitive. In contrast, in higher vertebrates, the direct photosensitivity of the pineal gland had been lost. Rather, the action of this gland as a relay between environmental light conditions and body functions involves reception of light information by the retina. In parallel to this sensory regression, the pineal gland (and its accessory organs) appears to have lost several functions in relation to light and temperature, which are important in lower vertebrate species. In humans, the functions of the pineal gland overlap with the functions of melatonin. They are extremely widespread and include general effects both on cell protection and on more precise functions, such as sleep and immunity. Recently, the role of melatonin has received a considerable amount of attention due to increased cancer risk in shift workers and the discovery that patients suffering from neurodegenerative diseases, autism, or depression exhibit abnormal melatonin rhythms.

    2015-01-01

    Background A uterine malformation is a type of female genital malformation resulting from abnormal development of the Mullerian duct(s) during embryogenesis. The type and degree of uterine malformation depends on the level at which the fusion process of the two Mullerian ducts stops; thus, there is a wide variety of malformations. A newly described deformity called accessory cavitated uterine mass (ACUM) has been increasingly reported. The case We report this deformity (in a 20-year-old married woman) which appears to be an additional incompletely developed, cavitated and presumably non-communicating uterus in addition to a normally shaped and developed uterus. The former uterus became impregnated with twins that died in a missed abortion at 13 weeks of gestation. Before discovering the presence of the deformity, three attempts were made to evacuate the dead fetuses by cervical dilatation and curettage of the normal empty uterus. These attempts resulted in perforation of its fundus, a laparotomy was performed to repair the uterus. During the laparotomy, the pregnant accessory uterus was discovered and was excised with the dead twins. Discussion The lack of good medical history was a cause of the mismanagement of this patient. Most probably, the origin of ACUM is a growth from the right Mullerian duct. The ovum has entered the ACUM through the rudimentary tube and has been fertilized by a sperm travelled either through the normal vaginal and uterine cavities or through the lymphatics. Conclusions (1) A detailed case history is important. (2) An ACUM can be impregnated. PMID:25813124

    We present a rare case of carcinoma developing in an accessory breast. The patient presented with a progressive lump in her right axilla for 1 year. On examination, there was a well-developed nipple areola complex in the right axilla overlying a hard, fixed 5 × 3 cm lump. On investigation, core biopsy revealed poorly differentiated carcinoma of the breast. Mammography also revealed features of a malignant lesion with skin and muscle infiltration. Neoadjuvant chemotherapy was administered followed by modified radical mastectomy after three cycles. Immunohistochemistry study showed positive status of oestrogen and progesterone receptors, and negative HER-2 neu. Three more cycles of chemotherapy along with 50 Gy radiotherapy were given in an adjuvant setting followed by hormone therapy.

  15. Types of female genital mutilation.

    PubMed

    1998-03-01

    The two major types of female genital mutilation include clitoridectomy and excision with infibulation. Clitoridectomy involves removal of the clitoris, part of all of the labia minora, and, often, all external soft genital tissue. Excision with infibulation involves all of this as well as removing the sides of the labia majora, abrading the sides of the vulva, and joining the bleeding sides of the vulva with thorns or a paste. A small opening is all that is allowed to remain for the passage of urine and menstrual blood. In Western Africa, infibulation is accomplished by tying the legs of the affected girls together in a crossed position immediate after the operation. These girls are immobilized for several weeks until the wound has closed. Infibulation is sometimes referred to a "pharaonic" because it occurred in ancient Egypt. Infibulated women must be cut open to allow sexual intercourse or child birth. Women are traditionally reinfibulated after child birth and then reopened when the child is weaned. Female genital mutilation is performed in septic conditions using the same tool on a group of girls. Fatalities are blamed on evil spirits or are said to occur because the victim was not a virgin.

Herpes simplex virus type 2 (HSV-2) was cultured from the effluent and the genital lesions. Primary HSV-2 infection was diagnosed by serology. This is the first documented case of PD peritonitis caused by HSV-2. We speculate that cases of culture-negative PD peritonitis may be due to recurrences of genital herpes.

    Genital allergy should be considered as a possible diagnosis in all patients with genital soreness or irritation for which no infection or dermatosis can be identified and in whom symptoms remain unchanged or worsen with treatment. It is an underreported and underdiagnosed condition as patients may not complain about symptoms in this area. Moreover, diagnosis and therapy may not often be conducted by a dermatologist or allergologist. Therefore, many cases of allergic diseases in the genital area remain undetected. PMID:27190404

    Glutathione peroxidase-5 (GPX5) is an H2O2-scavenging enzyme identified in boar seminal plasma (SP). This study attempted to clarify its origin and role on sperm survival and fertility after artificial insemination (AI). GPX5 was expressed (Western blot and immunocytochemistry using a rabbit primary polyclonal antibody) in testes, epididymis and accessory sex glands (6 boars). SP-GPX5 concentration differed among boars (11 boars, P < 0.001), among ejaculates within boar (44 ejaculates, P < 0.001) and among portions within ejaculate (15 ejaculates). The first 10 mL of the sperm rich fraction (SRF, sperm-peak portion) had a significantly lower concentration (8.87 ± 0.78 ng/mL) than the rest of the SRF and the post-SRF (11.66 ± 0.79 and 12.37 ± 0.79 ng/mL, respectively, P < 0.005). Sperm motility of liquid-stored semen AI-doses (n = 44, at 15-17°C during 72h) declined faster in AI-doses with low concentrations of SP-GPX5 compared to those with high-levels. Boars (n = 11) with high SP-GPX5 showed higher farrowing rates and litter sizes than those with low SP-GPX5 (a total of 5,275 inseminated sows). In sum, GPX5 is widely expressed in the boar genital tract and its variable presence in SP shows a positive relationship with sperm quality and fertility outcomes of liquid-stored semen AI-doses.

  1. The Accessory Genome of Pseudomonas aeruginosa

    PubMed Central

    Kung, Vanderlene L.; Ozer, Egon A.; Hauser, Alan R.

    2010-01-01

    Summary: Pseudomonas aeruginosa strains exhibit significant variability in pathogenicity and ecological flexibility. Such interstrain differences reflect the dynamic nature of the P. aeruginosa genome, which is composed of a relatively invariable “core genome” and a highly variable “accessory genome.” Here we review the major classes of genetic elements comprising the P. aeruginosa accessory genome and highlight emerging themes in the acquisition and functional importance of these elements. Although the precise phenotypes endowed by the majority of the P. aeruginosa accessory genome have yet to be determined, rapid progress is being made, and a clearer understanding of the role of the P. aeruginosa accessory genome in ecology and infection is emerging.

  2. Laparoscopic excision of infarcted accessory spleen.

    PubMed

    2010-04-01

    An accessory spleen is present in about 10-30% of the population and, usually, does not cause symptoms. We present a case report of an unusual presentation of accessory spleen infarction, with a literature review. A 12-year old male presented with acute left-upper quadrant pain that slowly resolved. An ultrasound and computed tomography scan showed a 3.5 x 2.5 x 2 cm solid mass abutting and displacing the splenic flexure of the colon, with surrounding inflammatory changes. This was interpreted as a colonic duplication cyst, and the boy was treated with antibiotics and underwent elective laparoscopic exploration. It was removed laparoscopically without complication and, on pathologic examination, proved to be consistent with an infarcted accessory spleen. Less than two dozen similar cases of accessory spleen infarction have been reported in the literature, most presenting with acute abdominal pain. Preoperative diagnoses included appendicitis, ovarian torsion, neoplasm, and, in our case, colonic duplication. The natural course of infarcted accessory spleen would be to atrophy, but, even with advanced imaging techniques, it may be impossible to diagnose infarcted accessory spleen with enough confidence to avoid surgery.

  3. Predictors of Genital Pain in Young Women

    Farmer, Melissa A.; Meston, Cindy M.

    2010-01-01

    Despite the high prevalence of genital pain in healthy young adult women, limited research has addressed genital pain during intercourse using contemporary models of multidimensional sexual function. The objectives of this study were threefold: (1) to identify differences in sexual functioning in women who experience genital pain compared to pain free women; (2) to identify predictors of sexual functioning in women with and without genital pain; and (3) to identify predictors of sexual satisfaction in women with and without genital pain. Sexually active female undergraduates (n = 651) were administered the Female Sexual Function Index and the Derogatis Sexual Functioning Inventory. We evaluated the sexual factors that impact the sexual function of women with any pain (including high and low pain groups) versus women with no history of pain. Women with genital pain reported greater rates of sexual dysfunction as compared to pain-free women; however, sexual functioning in the high versus low pain groups was distinguished primarily by vaginal lubrication. Women in the high pain group showed negative correlations between domains of sexual satisfaction and genital pain frequency and intensity that were not found in the low pain group. For pain-free women, intercourse played a strong role in sexual satisfaction, whereas non-intercourse sexual behavior was central to sexual satisfaction in women who reported pain. The evaluation of levels of genital pain may provide insight into the mechanisms underlying the impairment of sexual function, sexual behavior, and sexual satisfaction. PMID:17674182

    Eleven entire and twelve castrated male pigs were implanted with trenbolone acetate and the effects of the treatment on genital tract macro- and microscopical modifications were evaluated and compared to non-implanted animals. In entire male pigs a reduction of testicular weight and size was observed as a consequence of the treatment (< 0.001), but no important modifications were found in bulbourethral gland and seminal vesicles macroscopically. Castrated non-implanted males had bulbourethral gland atrophy (P < 0.01), while castrated implanted ones showed similar development to entire males. As for vesicular glands there were no significant differences among the four groups under study. Histological study of prostate has demonstrated structural modifications. As a consequence of the treatment glandular lumen was increased (P < 0.05), and most parenchyma was occupied by polymorphous cysts.

    As one of the most common sexually transmitted diseases, genital herpes is a global medical problem with significant physical and psychological morbidity. Genital herpes is caused by herpes simplex virus type 1 or type 2 and can manifest as primary and/or recurrent infection. This manuscript provides an overview about the fundamental knowledge on the virus, its epidemiology, and infection. Furthermore, the current possibilities of antiviral therapeutic interventions and laboratory diagnosis of genital herpes as well as the present situation and perspectives for the treatment by novel antivirals and prevention of disease by vaccination are presented. Since the medical management of patients with genital herpes simplex virus infection is often unsatisfactory, this review aims at all physicians and health professionals who are involved in the care of patients with genital herpes. The information provided would help to improve the counseling of affected patients and to optimize the diagnosis, treatment, and prevention of this particular disease. PMID:27358569

  9. Prevention agenda for genital herpes.

    PubMed

    Handsfield, H H; Stone, K M; Wasserheit, J N

    1999-04-01

    Few meeting participants envisioned a prevention and control program on the scale or scope of CDC's programs to prevent HIV infection, syphilis, gonorrhea, and chlamydial infection, but all agreed that the virtual absence of public health interventions to prevent genital herpes is no longer appropriate in light of evolving epidemiologic knowledge and other research advances. The ultimate scope of a national genital herpes prevention effort will depend in part on the results of the recommended research agenda, which probably will evolve over the better part of a decade. Numerous other STD prevention partners will also need to contribute to this effort and help to determine the makeup of future programs. Substantial new fiscal resources will be required both to implement the proposed research agenda and, depending on the results, to undertake the prevention efforts indicated by those studies. Competing STD prevention priorities and other national health needs will influence the availability of those resources. The consultants' meeting and the research and program activities summarized above are described in more detail in the full meeting report, which is posted on the Division's web site (www.cdc.gov/nchstp/dstd/dstdp.html) or may be requested directly from the Division. DSTDP is interested in receiving comments and suggestions about herpes prevention.

    The number of migrants and refugees with a female genital mutilation (FGM) living in Greece is rising. This study explores the characteristics and psychosexual issues of women with FGM who were examined in the 2nd Department of Obstetrics and Gynecology, University of Athens Medical School, Greece during the year 2009. The women were asked to fill out an anonymous questionnaire asking for demographic data, obstetric history, current complaints, and psychosexual problems. The results are presented and discussed, as FGM is a new reality for Greece. Healthcare providers have to familiarize themselves with issues related to FGM and improve their skills in transcultural care, so as to manage and support women with FGM adequately.

    There are two opposing approaches in the treatment of genital warts: (1) the traditional approach advocates complete elimination of all lesions, and (2) a second approach regards condyloma as merely a cosmetic nuisance. After a long journey through many arguments and scientific papers, we have concluded that many unknowns, uncertainties, and controversies concerning the value of treatment of genital warts in terms of clearing and curing the disease (ie, eradicating the viruses, preventing cancer, and reducing infectivity). There is no consensus at present of whether treatment of men with evidence of genital human papillomavirus infection influences the natural history of their female sex partner's cervical disease.

    2009-10-01

    Lipschütz acute genital ulcer is a rare distinctive cause of nonvenereal acute genital ulcers that occurs particularly in adolescents described in 1913. We report here a typical case that occurred in a 24-year-old virgin woman who developed flu-like symptoms and painful genital ulcers that healed spontaneously within a week and without any infection (Epstein Barr Virus, toxoplasmosis, salmonella). The physiopathogeny remains unknown. However, there are body of evidences pointing out a possible link to several nonvenereal infections, including mainly Epstein-Barr virus acute infection. This rare benign but disabling entity should be known by gynecologists.

  4. Controlled Speed Accessory Drive demonstration program

    Hoehn, F. W.

    1981-01-01

    A Controlled Speed Accessory Drive System was examined in an effort to improve the fuel economy of passenger cars. Concept feasibility and the performance of a typical system during actual road driving conditions were demonstrated. The CSAD system is described as a mechanical device which limits engine accessory speeds, thereby reducing parasitic horsepower losses and improving overall vehicle fuel economy. Fuel consumption data were compiled for fleets of GSA vehicles. Various motor pool locations were selected, each representing different climatic conditions. On the basis of a total accumulated fleet usage of nearly three million miles, an overall fuel economy improvement of 6 percent to 7 percent was demonstrated. Coincident chassis dynamometer tests were accomplished on selected vehicles to establish the effect of different accessory drive systems on exhaust emissions, and to evaluate the magnitude of the mileage benefits which could be derived.

  5. Reutilization of accessories in gastrointestinal endoscopic practice.

    PubMed

    Haber, G

    2000-10-01

    The key issues that determine the decision between reusable versus disposable accessories are cost and functionality. In most health-care systems the availability and dissemination of endoscopic services relates directly to the resources (i.e. budget) of that system. Given the limitations of health-care budgets, access to endoscopic services will depend upon the cost efficiency of endoscopic practice. The onus on endoscopists and health-care providers, therefore, is to meticulously evaluate the necessary steps for safe reutilization of accessories. This paper addresses the principles of reuse, quality assurance and particularly disinfection practices. Any change to a more costly disposable accessory policy must bear the responsibility of denied access to endoscopic services in a system with finite resources.

    Herpes simplex virus infection and syphilis are the most common causes of genital ulcers in the United States. Other infectious causes include chancroid, lymphogranuloma venereum, granuloma inguinale (donovanosis), secondary bacterial infections, and fungi. Noninfectious etiologies, including sexual trauma, psoriasis, Behçet syndrome, and fixed drug eruptions, can also lead to genital ulcers. Although initial treatment of genital ulcers is generally based on clinical presentation, the following tests should be considered in all patients: serologic tests for syphilis and darkfield microscopy or direct fluorescent antibody testing for Treponema pallidum, culture or polymerase chain reaction test for herpes simplex virus, and culture for Haemophilus ducreyi in settings with a high prevalence of chancroid. No pathogen is identified in up to 25 percent of patients with genital ulcers. The first episode of herpes simplex virus infection is usually treated with seven to 10 days of oral acyclovir (five days for recurrent episodes). Famciclovir and valacyclovir are alternative therapies. One dose of intramuscular penicillin G benzathine is recommended to treat genital ulcers caused by primary syphilis. Treatment options for chancroid include a single dose of intramuscular ceftriaxone or oral azithromycin, ciprofloxacin, or erythromycin. Lymphogranuloma venereum and donovanosis are treated with 21 days of oral doxycycline. Treatment of noninfectious causes of genital ulcers varies by etiology, and ranges from topical wound care for ulcers caused by sexual trauma to consideration of subcutaneous pegylated interferon alfa-2a for ulcers caused by Behçet syndrome.

  10. Electronic Position Sensor for Power Operated Accessory

    DOEpatents

    Haag, Ronald H.; Chia, Michael I.

    2005-05-31

    An electronic position sensor for use with a power operated vehicle accessory, such as a power liftgate. The position sensor includes an elongated resistive circuit that is mounted such that it is stationary and extends along the path of a track portion of the power operated accessory. The position sensor further includes a contact nub mounted to a link member that moves within the track portion such that the contact nub is slidingly biased against the elongated circuit. As the link member moves under the force of a motor-driven output gear, the contact nub slides along the surface of the resistive circuit, thereby affecting the overall resistance of the circuit. The position sensor uses the overall resistance to provide an electronic position signal to an ECU, wherein the signal is indicative of the absolute position of the power operated accessory. Accordingly, the electronic position sensor is capable of providing an electronic signal that enables the ECU to track the absolute position of the power operated accessory.

    In two patients with recurrent immune thrombocytopenia, accessory splenic tissue was demonstrated by radionuclide imaging following administration of indium 111-labeled autologous platelets. In one of these patients, no accessory splenic tissue was seen on images obtained with technetium 99m sulfur colloid. This new technique provides a simple means for demonstrating accessory spleens and simultaneously evaluating the life-span of autologous platelets.

  19. Genital Chlamydia trachomatis: An update

    PubMed Central

    Malhotra, Meenakshi; Sood, Seema; Mukherjee, Anjan; Muralidhar, Sumathi; Bala, Manju

    2013-01-01

    Chlamydia trachomatis is the most common cause of curable bacterial sexually transmitted infection (STI) worldwide. It manifests primarily as urethritis in males and endocervicitis in females. Untreated chlamydial infection in man can cause epididymitis and proctitis. Though most women with Chlamydia infection are asymptomatic or have minimal symptoms, some develop salpingitis, endometritis, pelvic inflammatory disease (PID), ectopic pregnancy and tubal factor infertility. It is associated with an increased risk for the transmission or acquisition of HIV and is also attributed to be a risk factor for the development of cervical carcinoma. Early diagnosis and treatment of infected individuals is required to prevent the spread of the disease and severe sequelae. Traditionally, tissue culture was considered the gold standard for the diagnosis. However, with the availability of newer diagnostic techniques particularly molecular methods which are not only highly sensitive and specific but are cost-effective also, the diagnosis has became fast and easy. The purpose of this review is to study the various aspects of genital C. trachomatis infection. Also the advances related to the clinical picture, various diagnostic modalities, prevention, treatment, drug resistance and control measures will be dealt with. PMID:24135174

  20. Controversial issues: female genital mutilation.

    PubMed

    Richards, D

    2000-01-01

    As immigrant women from African countries enter the U.S., Canada, Australia, and Western Europe, western health care providers are beginning to see patients affected by the cultural practice of Female Genital Mutilation (FGM). Unfamiliar with the practice, either medically or culturally, these providers are turning to medical librarians for information. Complicating the issue are the strong negative feelings most western health care workers have about FGM, which appears to them to be both barbaric and cruel. These feelings may conflict strongly with those of their immigrant patients, who regard the practice as normal and desirable. Both medical and cultural information are needed for the professional to provide treatment of medical conditions, while also establishing a good relationship with the FGM affected patient. This article identifies and describes the most important refereed journal article databases, available now over the Internet, providing both medical and cultural information on FGM, and the most useful Web sites for health professionals, librarians, and interested laypersons who need information about this difficult multicultural issue.

  1. Laser hair removal for genital gender affirming surgery

    PubMed Central

    Zhang, William R.; Garrett, Giorgia L.; Arron, Sarah T.

    2016-01-01

    Genital gender affirming surgery (GAS) involves reconstruction of the genitals to match a patient’s identified sex. The use of hair-bearing flaps in this procedure may result in postoperative intra-vaginal and intra-urethral hair growth and associated complications, including lower satisfaction with genital GAS. Despite the significant increase in genital GAS within the past 50 years, there is limited data regarding hair removal practices in preparation for genital GAS and notable variation in hair removal techniques among dermatologists and other practitioners. We present a literature review, recommendations from our experience, and a practical laser hair removal (LHR) approach to hair removal prior to genital GAS. PMID:27298787

The use of hair-bearing flaps in this procedure may result in postoperative intra-vaginal and intra-urethral hair growth and associated complications, including lower satisfaction with genital GAS. Despite the significant increase in genital GAS within the past 50 years, there is limited data regarding hair removal practices in preparation for genital GAS and notable variation in hair removal techniques among dermatologists and other practitioners. We present a literature review, recommendations from our experience, and a practical laser hair removal (LHR) approach to hair removal prior to genital GAS. PMID:27298787

    The study of genital diversity has experienced rapidly burgeoning attention over the past few decades. This research has shown that male genitalia in internally fertilizing animals exhibit remarkably rapid and complex evolution. In recent years, a consensus has emerged that sexual selection is responsible for much of the observed genital diversity, with natural selection largely playing a subsidiary role. Despite enhanced understanding of the key proximate forms of selection responsible for genital evolution, we still have a poor grasp of the broader, ultimate causes and consequences of the striking diversity of genitalia. Here, we highlight three topics that have so far received comparatively little attention and yet could prove critically important. First, we encourage investigation of ecology's direct and indirect roles in genital diversification, as ecological variation can influence selection on genitalia in several ways, perhaps especially by influencing the context of sexual selection. Second, we need more research into the effects of genital divergence on speciation, as genital differences could enhance reproductive isolation through either a lock-and-key process (where selection directly favors reproductive isolation) or as an incidental by-product of divergence. Third, we echo recent calls for increased research on female genitalia, as non-trivial female genital diversity exists, and multiple mechanisms can lead to rapid diversification of female genitalia. For all three topics, we review theory and empirical data, and describe specific research approaches for tackling these questions. We hope this work provides a roadmap toward increased understanding of the causes and consequences of the conspicuous diversity of primary sexual traits, and thus toward new insights into the evolution of complex traits and the phenotypic causes of speciation.

    Benign myoepithelioma is a very rare form of salivary gland tumor, composed entirely of myoepithelial cells. It accounts for approximately 1% of all salivary gland tumors and is most frequently located in the parotid gland and in the minor salivary glands of the hard palate. We describe herein the ninth reported case of myoepithelioma of the submandibular gland. Benign myoepithelioma must be differentiated from several benign and malignant epithelial and mesenchymal tumors. Immunohistochemical staining can help differentiate between these conditions, but histopathology remains the gold standard for diagnosing this neoplastic process.

    Caecilians are exceptional among the vertebrates in that males retain the Mullerian duct as a functional glandular structure. The Mullerian gland on each side is formed from a large number of tubular glands connecting to a central duct, which either connects to the urogenital duct or opens directly into the cloaca. The Mullerian gland is believed to secrete a substance to be added to the sperm during ejaculation. Thus, the Mullerian gland could function as a male accessory reproductive gland. Recently, we described the male Mullerian gland of Uraeotyphlus narayani using light and transmission electron microscopy (TEM) and histochemistry. The present TEM study reports that the secretory cells of both the tubular and basal portions of the tubular glands of the male Mullerian gland of this caecilian produce secretion granules in the same manner as do other glandular epithelial cells. The secretion granules are released in the form of structured granules into the lumen of the tubular glands, and such granules are traceable to the lumen of the central duct of the Mullerian gland. This is comparable to the situation prevailing in the epididymal epithelium of several reptiles. In the secretory cells of the basal portion of the tubular glands, mitochondria are intimately associated with fabrication of the secretion granules. The structural and functional organization of the epithelium of the basal portion of the tubular glands is complicated by the presence of basal cells. This study suggests the origin of the basal cells from peritubular tissue leukocytes. The study also indicates a role for the basal cells in acquiring secretion granules from the neighboring secretory cells and processing them into lipofuscin material in the context of regression of the Mullerian gland during the period of reproductive quiescence. In these respects the basal cells match those in the epithelial lining of the epididymis of amniotes.

    Aims To describe a cohort of boys with genital injuries in whom child abuse was suspected. Methods Boys with genital injury (penile and/or scrotal) and referred to paediatricians in Leeds, population 750 000, with concerns regarding possible abuse from 1983 to 2003 were identified from medical reports. Results 86 boys (average age 62.7 months, median age 48 months) were referred between 1983 and 2003. The injury was judged inflicted in 63, unexplained, suspicious or inconsistent with the history given in 17 and accidental in six. The number of discrete injuries ranged from one in 57, two in 15, three in 12, to more than three in two cases. Genital injuries included burns in seven boys, bruises in 27, incised wounds, lacerations or scars in 39, and other traumatic lesions in 27. Non‐genital findings included anal findings in 28, >10 bruises in 17, fractures in three, burns in 12, mouth injuries in four, brain and retinal haemorrhages in one, and poor nourishment or underweight in 14. The categories of abuse were physical (eight), sexual (19), both physical and sexual (eight), physical and neglect (four), and physical, sexual and neglect (one). The category of abuse was unspecified in 39 children. Conclusions Genital injury in boys may be the result of abuse which may be physical or sexual in nature. PMID:17376938

    Using conventional anatomical methods, renal arteries of 140 human fetuses were studied. It was found (21.1%) that the accessory renal arteries occurred in a three-fold manner: 1. as single arteries (19.2%), 2. as double arteries (2.1%) and 3. as triplex arteries (0.7%). More often they originated from the right part of the circumference of the abdominal aorta, mainly in the female fetuses. These arteries penetrated the following segments of the kidney: the inferior (12.9%), the superior (2.3%), the anterior inferior (2.8%), the posterior (2.1%) and the anterior superior (1.5%). They crossed the renal pelvis more often in front (12.2%) than from behind of it (5%). The frequency of the occurrence of the accessory arteries depends not from the age of the fetus. PMID:9082875

    The study investigated the effectiveness of two online resources aimed at improving women's knowledge of the variation in normal female genital appearance and their attitudes towards their own genitals. The first consisted of a photographic array of normal female genitals and the second consisted of a video addressing digital airbrushing of women's genitals in media images. A sample of 136 female undergraduate students were randomly assigned to view the photographs, video, both the photographs and video, or neither. The video significantly increased women's perceptions of genital appearance diversity as well as awareness of digital airbrushing of genital images. Owing to relatively low levels of genital appearance concern, there was no effect of either resource on women's attitudes towards their own genitals; however, women who viewed the video indicated they would pass on their knowledge to help other women. Our results suggest that an educational video could be a useful tool. PMID:26723015

  11. Current Concepts for Genital Herpes Simplex Virus Infection: Diagnostics and Pathogenesis of Genital Tract Shedding.

    PubMed

    Johnston, Christine; Corey, Lawrence

    2016-01-01

    Herpes simplex virus 2 (HSV-2) is a DNA virus that is efficiently transmitted through intimate genital tract contact and causes persistent infection that cannot be eliminated. HSV-2 may cause frequent, symptomatic self-limited genital ulcers, but in most persons infection is subclinical. However, recent studies have demonstrated that the virus is frequently shed from genital surfaces even in the absence of signs or symptoms of clinical disease and that the virus can be transmitted during these periods of shedding. Furthermore, HSV-2 shedding is detected throughout the genital tract and may be associated with genital tract inflammation, which likely contributes to increased risk of HIV acquisition. This review focuses on HSV diagnostics, as well as what we have learned about the importance of frequent genital HSV shedding for (i) HSV transmission and (ii) genital tract inflammation, as well as (iii) the impact of HSV-2 infection on HIV acquisition and transmission. We conclude with discussion of future areas of research to push the field forward.

    The effect of cigarette smoke (CS) on histology of male accessory reproductive organs and the possible protective effect of honey supplementation in rats were investigated in this study. Rats received distilled water, honey, CS exposure or honey plus CS exposure. Honey (1.2 g/kg body weight/day) was administered by gavage and CS exposure (3 times per day) was done in a chamber for 13 weeks. CS exposure significantly increased relative weight of epididymis and ventral prostate. There were also significantly increased number of clear cells and epithelial height of cauda epididymis as well as severe interstitial oedema and decreased epithelial height of prostate gland. However, with the supplementation of honey, these histological changes were significantly reversed suggesting the protective effect of honey against the toxic effect of CS on male accessory reproductive organs in rats.

    Functional morphology of the genital organs is a key knowledge component for enhanced understanding of physiological patterns and for the determination of the reproductive performance in wild species. This study examines the morphology of genital organs of 133 paca females in the wild. Estimated conceptions and parturitions were mostly (83.7% and 75.5%, respectively) localized in the wet season. The pregnancy rate between 57.1% and 61.4% suggests an estimated yearly production of 1.37-1.48 parturitions and a long estimated farrowing interval of 247-266 days. Although large antral follicles were observed in all females, pregnant females had a greater number of antral follicles than females in the luteal phase. The average litter size was 1.03 foetuses per pregnant female, and mean ovulation rate was 1.33 follicles, resulting in a rate of reproductive wastage of 28.7%. The constituent active luteal tissues of the ovary were oestrous cyclic, pregnancy and accessory CL. The 50% of pregnant females in the late pregnancy stage lacked pregnancy CL, suggesting that placenta may become the mean source of progesterone during late stages of pregnancy. Results of the present study suggest that the observation of the vaginal closure membrane should not be an accurate tool for diagnosing oestrus in the paca female.

The results show a preponderance of non-neoplastic pathology. Benign tumors were found in 6% of glands, primary glandular and metastatic carcinoma in 3%. Timely treatment of a submandibular gland mass is indicated due to the relatively aggressive behavior of malignancies originating in this location.

    Female genital mutilation (FGM) is considered to be against the law and against morality not only in Western countries, although a woman of age and able to consent may sometimes think differently. The procedure may have serious physical and emotional consequences for the girl or woman. Nevertheless there are attempts to justify the procedure with medical and hygienic pseudoarguments, ideology, freedom of religion, cultural identity and social adequacy. Outside the Western world, some people claim that religion and culture alone justify the practice. In Germany, parents can lose the right to determine the residence of their daughter, if she is faced with the risk of genital mutilation in order to prevent that the child or girl is taken to her home country. Genital mutilation as a gender-specific threat is recognized as a reason to grant asylum or prevent deportation. Proposals to make genital mutilation a separate punishable offence are presently discussed by the legislator.

This review outlines our knowledge of the histopathology, lipid abnormalities and role of microorganisms in meibomian gland dysfunction. We will also review the physiology of meibomian gland secretion and present models of meibomian gland dysfunction which have enhanced our knowledge of this condition. The importance of diagnosing associated conditions such as aqueous tear deficiency, contact lens intolerance, rosacea, and seborrheic dermatitis is emphasized. Although this condition causes significant morbidity in the population, there are effective treatments available and these will be discussed.

    We report on a 45-yr-old male sports instructor with chronic pain and instability of the ankle. He was a recreational basketball player, but because of repeated ankle sprains and chronic subtalar pain this activity became impossible. The radiologic findings were compatible with the diagnosis of accessory calcaneus. In an initial therapeutic approach the patient was treated conservatively with taping and physical therapy, but this failed to relieve the symptoms. Next, a ligamentoplasty was performed. The instability improved, but the pain remained the same. Finally the accessory calcaneus was resected and short term follow-up was unremarkable. Accessory calcaneus is an uncommon anatomical variation that may cause subtalar pain and instability. Resection of the accessory bone may be necessary to provide relief of symptoms. Accessory calcaneus can be well demonstrated on CT, SPECT-CT, and MR. MR and nuclear medicine can indicate instability of the accessory bone by showing bone marrow edema on MR or uptake on fusion imaging.

    The diversity, variability, and apparent rapid evolution of animal genitalia are a vivid focus of research in evolutionary biology, and studies exploring genitalia have dramatically increased over the past decade. These studies, however, exhibit a strong male bias, which has worsened since 2000, despite the fact that this bias has been explicitly pointed out in the past. Early critics argued that previous investigators too often considered only males and their genitalia, while overlooking female genitalia or physiology. Our analysis of the literature shows that overall this male bias has worsened with time. The degree of bias is not consistent between subdisciplines: studies of the lock-and-key hypothesis have been the most male focused, while studies of cryptic female choice usually consider both sexes. The degree of bias also differed across taxonomic groups, but did not associate with the ease of study of male and female genital characteristics. We argue that the persisting male bias in this field cannot solely be explained by anatomical sex differences influencing accessibility. Rather the bias reflects enduring assumptions about the dominant role of males in sex, and invariant female genitalia. New research highlights how rapidly female genital traits can evolve, and how complex coevolutionary dynamics between males and females can shape genital structures. We argue that understanding genital evolution is hampered by an outdated single-sex bias. PMID:24802812

    The traditional custom of ritual cutting and alteration of the genitalia of female infants, children, and adolescents, referred to as female genital mutilation or female genital cutting (FGC), persists primarily in Africa and among certain communities in the Middle East and Asia. Immigrants in the United States from areas in which FGC is common may have daughters who have undergone a ritual genital procedure or may request that such a procedure be performed by a physician. The American Academy of Pediatrics believes that pediatricians and pediatric surgical specialists should be aware that this practice has life-threatening health risks for children and women. The American Academy of Pediatrics opposes all types of female genital cutting that pose risks of physical or psychological harm, counsels its members not to perform such procedures, recommends that its members actively seek to dissuade families from carrying out harmful forms of FGC, and urges its members to provide patients and their parents with compassionate education about the harms of FGC while remaining sensitive to the cultural and religious reasons that motivate parents to seek this procedure for their daughters.

    Understanding differences in genital injuries after nonconsensual and consensual intercourse is an important element of prosecuting sexual assault cases. In order to determine if the injury patterns and total surface area of genital injuries can differentiate between the types of intercourse (consensual or non-consensual), eighty women were examined after non-consensual (retrospective chart review, n = 40) and consensual (recruited, n = 40) intercourse within 48 hours using colposcopy, toluidine blue dye, and digital photography to document genital injuries. Differences between types of injuries found in the nonconsensual and consensual groups, based on the univariate analysis, were found with the number of sites (NoS) with ecchymosis (p < 0.01) and NoS with redness (p < 0.01). Based on the logistic hierarchical regression model, 85% of the nonconsensual group and 90% of the consensual group were classified correctly by using the NoS with tears, ecchymosis, abrasions, and redness and SA of injury when controlling for time from intercourse to examination. The NoS with redness (p = 0.017), NoS with ecchymosis, and SA of injury (p = 0.039) were individually predictive. The NoS with ecchymosis were also a significant finding when addressed as an individual block (p < 0.001). In this small sample, exploratory study, while controlling for time, the injury patterns and total SA of genital injuries were able to correctly classify the nonconsensual group 85% of the time. Replication of this study with a larger sample is essential.

    Genital psoriasis is a neglected manifestation of psoriasis, although it affects numerous patients and has major effects on sexual quality of life (SQoL). We aimed to assess the value of specialised care for patients with genital psoriasis. Patients were treated for at least one year at a specialised research outpatient clinic with extensive attention for genital lesions and SQoL. The genital lesions were treated according to a stepwise algorithm. First follow-up was planned after 6 weeks; subsequent follow-up visits were scheduled every 3 months. At every visit, psoriasis severity and SQoL were measured with validated tools. Differences in scores between visits were analysed by a mixed model for repeated measures. Forty-two patients were included (M:F = 25:17). All objective and subjective genital psoriasis severity and QoL parameters improved significantly within the first follow-up period of approximately 6 weeks. In female patients, SQoL also significantly improved. In conclusion, genital psoriasis can relatively easy be treated within limited time exposure, resulting in significant improvement of QoL. Prompt and simple adjustments in the provided care are enough to accomplish this.

    The number of accessory sperm found in the zona pellucida of porcine embryos was correlated to their individual quality and to the embryo quality range found within a single sow. Our goal was to determine whether accessory sperm counts provide semen evaluation with additional, useful information. Accessory sperm count was highest when only normal embryos were found in a given sow and diminished if oocytes or degenerated embryos were present (P<0.01). Within a given sow, normal embryos had higher (P<0.05) accessory sperm counts than degenerated embryos, although not when oocytes were also present. Fertilization capacity of sperm is optimal when only normal embryos are found in a given sow; this capacity is indicated by high accessory sperm counts. A decrease in fertilization capacity is reflected in diminishing accessory sperm counts. The boar had a significant effect (P<0.01) on accessory sperm count, but not on the percentage of normal embryos; this suggests that accessory sperm may be more sensitive indicators of the fertilization capacity of sperm than the percentage of normal embryos. We conclude that accessory sperm count can be used for the detection of compensable defects in sperm and is a valid parameter for assessing sperm fertilization capacity.

    Male reproductive gland proteins (mRGPs) impact the physiology and/or behavior of mated females in a broad range of organisms. We sought to identify mRGPs of the yellow fever mosquito, Aedes aegypti, the primary vector of dengue and yellow fever viruses. Earlier studies with Ae. aegypti demonstrated that "matrone" (a partially purified male reproductive accessory gland substance) or male accessory gland fluid injected into virgin female Ae. aegypti affect female sexual refractoriness, blood feeding and digestion, flight, ovarian development, and oviposition. Using bioinformatic comparisons to Drosophila melanogaster accessory gland proteins and mass spectrometry of proteins from Ae. aegypti male accessory glands and ejaculatory ducts (AG/ED) and female reproductive tracts, we identified 63 new putative Ae. aegypti mRGPs. Twenty-one of these proteins were found in the reproductive tract of mated females but not of virgin females suggesting that they are transferred from males to females during mating. Most of the putative mRGPs fall into the same protein classes as mRGPs in other organisms, although some appear to be evolving rapidly and lack identifiable homologs in Culex pipiens, Anopheles gambiae, and D. melanogaster. Our results identify candidate male-derived molecules that may have an important influence on behavior, survival, and reproduction of female mosquitoes.

    Podisus nigrispinus Dallas (Hemiptera: Pentatomidae) is a zoophytophagous insect with a potential for use as a biological control agent in agriculture because nymphs and adults actively prey on various insects by inserting mouthparts and regurgitating the contents of the salivary glands inside the prey, causing rapid paralysis and death. However, the substances found in saliva of P. nigrispinus that causes the death of the prey are unknown. As a first step to identify the component of the saliva of P. nigrispinus, this study evaluated the ultrastructure and cytochemistry of the salivary glands of P. nigrispinus. The salivary system of P. nigrispinus has a pair of principal salivary glands, which are bilobed with a short anterior lobe and a long posterior lobe, and a pair of tubular accessory glands. The principal gland epithelium is composed of a single layer of cells enclosing a large lumen. Epithelial cells of the principal salivary gland vary from cubic to columnar shape, with one or two spherical and well-developed nuclei. Cells of the anterior lobe of the principal salivary gland have an apical surface with narrow, short, and irregular plasma membrane foldings; apical and perinuclear cytoplasm rich in rough endoplasmic reticulum; and mitochondria with tubular cristae. The basal portion of the secretory cells has mitochondria associated with many basal plasma membrane infoldings that are short but form large extracellular canals. Secretory granules with electron-dense core and electron-transparent peripheral are dispersed throughout the cytoplasm. Cells of the posterior lobe of the principal salivary gland are similar to those of the anterior lobe, except for the presence of mitochondria with transverse cristae. The accessory salivary gland cells are columnar with apical microvilli, have well-developed nucleus and cytoplasm rich in rough endoplasmic reticulum, and have secretory granules. Cytochemical tests showed positive reactions for carbohydrate, protein

    Clinical and subclinical genital herpes simplex virus type 2 (HSV-2) reactivations have been associated with increases in human immunodeficiency virus (HIV)-1 genital shedding. Whether HSV-2 shedding contributes to the selection of specific genital HIV-1 variants remains unknown. We evaluated the genetic diversity of genital and blood HIV-1 RNA and DNA in 14 HIV-1/HSV-2-co-infected women, including seven with HSV-2 genital reactivation, and seven without as controls. HIV-1 DNA and HIV-1 RNA env V1-V3 sequences in paired blood and genital samples were compared. The HSV-2 selection pressure on HIV was estimated according to the number of synonymous substitutions (dS), the number of non-synonymous substitutions (dN) and the dS/dN ratio within HIV quasi-species. HIV-1 RNA levels in cervicovaginal secretions were higher in women with HSV-2 replication than in controls (p0.02). Plasma HIV-1 RNA and genital HIV-1 RNA and DNA were genetically compartmentalized. No differences in dS, dN and the dS/dN ratio were observed between the study groups for either genital HIV-1 RNA or plasma HIV-1 RNA. In contrast, dS and dN in genital HIV-1 DNA were significantly higher in patients with HSV-2 genital reactivation (p <0.01 and p <0.05, respectively). The mean of the dS/dN ratio in genital HIV-1 DNA was slightly higher in patients with HSV-2 genital replication, indicating a trend for purifying selection (p 0.056). HSV-2 increased the genetic diversity of genital HIV-1 DNA. These observations confirm molecular interactions between HSV-2 and HIV-1 at the genital tract level. PMID:26003280

  20. Reviewing prescription spending and accessory usage.

    PubMed

    Oxenham, Julie

    This article aims to explore the role of the stoma nurse specialist in the community and how recent initiatives within the NHS have impacted on the roles in stoma care to react to the rising prescription costs in the specialty. The article will explore how the stoma care nurse conducted her prescription reviews within her own clinical commissioning group (CCG). The findings of the reviews will be highlighted by a small case history and a mini audit that reveals that some stoma patients may be using their stoma care accessories inappropriately, which may contribute to the rise in stoma prescription spending. To prevent the incorrect use of stoma appliances it may necessitate an annual review of ostomates (individuals who have a stoma), as the author's reviews revealed that inappropriate usage was particularly commonplace when a patient may have not been reviewed by a stoma care specialist for some considerable amount of time. Initial education of the ostomate and ongoing education of how stoma products work is essential to prevent the misuse of stoma appliances, particularly accessories, as the reviews revealed that often patients were not always aware of how their products worked in practice.

  1. Computed tomographic imaging characteristics of the normal canine lacrimal glands

    PubMed Central

    2014-01-01

    Background The canine lacrimal gland (LG) and accessory lacrimal gland of the third eyelid (TEG) are responsible for production of the aqueous portion of the precorneal tear film. Immune-mediated, toxic, neoplastic, or infectious processes can affect the glands directly or can involve adjacent tissues, with secondary gland involvement. Disease affecting these glands can cause keratoconjunctivitis sicca, corneal ulcers, and loss of vision. Due to their location in the orbit, these small structures are difficult to evaluate and measure, making cross-sectional imaging an important diagnostic tool. The detailed cross-sectional imaging appearance of the LG and TEG in dogs using computed tomography (CT) has not been reported to date. Results Forty-two dogs were imaged, and the length, width, and height were measured and the volume calculated for the LGs & TEGs. The glands were best visualized in contrast-enhanced CT images. The mean volume of the LG was 0.14 cm3 and the TEG was 0.1 cm3. The mean height, width, and length of the LG were, 9.36 mm, 4.29 mm, and 9.35 mm, respectively; the corresponding values for the TEG was 2.02 mm, 9.34 mm, and 7.90 mm. LG and TEG volume were positively correlated with body weight (p < 0.05). Conclusions Contrast-enhanced CT is a valuable tool for noninvasive assessment of canine lacrimal glands. PMID:24886364

  2. EcPV2 DNA in equine genital squamous cell carcinomas and normal genital mucosa.

    Squamous cell carcinoma (SCC) represents the most common genital malignant tumor in horses. Similar to humans, papillomaviruses (PVs) have been proposed as etiological agents and recently Equine papillomavirus type 2 (EcPV2) has been identified in a subset of genital SCCs. The goals of this study were (1) to determine the prevalence of EcPV2 DNA in tissue samples from equine genital SCCs, penile intraepithelial neoplasia (PIN) and penile papillomas, using EcPV2-specific PCR, (2) to examine the prevalence of latent EcPV2 infection in healthy genital mucosa and (3) to determine genetic variability within EcPV2 and to disentangle phylogenetic relationships of EcPV2 among PVs. EcPV2 DNA was detected in all but one penile SCC (15/16), in all PIN lesions (8/8) and penile papillomas (4/4). Additionally, EcPV2 DNA was demonstrated in one of two metastasized lymph nodes, one contact metastasis in the mouth, two vaginal and one anal lesion. In healthy horses, EcPV2 DNA was detected in 10% (4/39) of penile swabs but in none of vulvovaginal swabs (0/20). This study confirms the presence of EcPV2 DNA in equine genital SCCs and shows its involvement in anal lesions, a lymph node and contact metastases. Latent EcPV2 presence was also shown in normal male genital mucosa. We found that different EcPV2 variants cocirculate among horses and that EcPV2 is related to the Delta+Zeta PVs and is only a very distant relative of high-risk human PVs causing genital cancer. Thus, similar viral tropism and similar malignant outcome of the infection do not imply close evolutionary relationship.

    2014-11-01

    There has been the controversy surrounding the cranial root (CR) of the accessory nerve. This study was performed to clarify the morphological characteristics of the CR in the cranial cavity. Fifty sides of 25 adult cadaver heads were used. The accessory nerve was easily distinguished from the vagus nerve by the dura mater in the jugular foramen in 80% of 50 specimens. The trunk of the accessory nerve from the spinal cord penetrated the dura mater at various distances before entering the jugular foramen. In 20% of the specimens there was no dural boundary. In these cases, the uppermost cranial rootlet of the accessory nerve could be identified by removing the dura mater around the jugular foramen where it joined to the trunk of the accessory nerve at the superior vagal ganglion. The cranial rootlet was formed by union of two to four short filaments emerging from the medulla oblongata (66%) and emerged single, without filament (34%), and usually joined the trunk of the accessory nerve directly before the jugular foramen. The mean number of rootlets of the CR was 4.9 (range 2-9) above the cervicomedullary junction. The CR of the accessory nerve was composed of two to nine rootlets, which were formed by the union of two to four short filaments and joined the spinal root of the accessory nerve. The CR is morphologically distinct from the vagus nerve, confirming its existence.

    Arora and Jacobs (2016) assume that liberal societies should tolerate non-therapeutic infant male circumcision, and argue that it follows from this that they should similarly tolerate-or even encourage-what the authors regard as 'de minimis' forms of female genital mutilation (as defined by the World Health Organization). In this commentary, I argue that many serious problems would be likely to follow from a policy of increased tolerance for female genital mutilation, and that it may therefore be time to consider a less tolerant attitude toward non-therapeutic infant male circumcision. Ultimately, I suggest that children of whatever sex or gender should be free from having healthy parts of their most intimate sexual organs either damaged or removed, before they can understand what is at stake in such an intervention and agree to it themselves.

    A 23-year-old woman presented with large exophytic genital wart arising from perineum, vulva, introitus of the vagina, and inner aspect of thighs. Patient developed severe itching and formication (insect-crawling sensation) in the lesions for past 1 week, though careful examination did not reveal any insects. Considering that the disease was causing psychological stress and physical symptoms, radiofrequency excision was planned. However, during the procedure, several maggots appeared from the crypts. The procedure was abandoned and maggots were removed manually. Subsequently external giant warts were removed using radiofrequency device. There was no recurrence of excised warts during 3 month follow-up. To our knowledge, this is the second reported case of maggots in genital warts. PMID:21976905

    Background. It is not known if fluctuations in genital tract antiretroviral drug concentrations correlate with genital virus shedding in human immunodeficiency virus (HIV)–infected women on antiretroviral therapy (ART). Methods. Among 20 HIV-infected women on ART (tenofovir [TFV], emtricitabine [FTC], and ritonavir-boosted atazanavir [ATV]) with suppressed plasma virus loads, blood and cervicovaginal samples collected twice weekly for 3 weeks were tested for antiretroviral concentrations, HIV-1 RNA, and proviral DNA. Results. Cervicovaginal:plasma antiretroviral concentration ratios were highest for FTC (11.9, 95% confidence interval [CI], 8.66–16.3), then TFV (3.52, 95% CI, 2.27–5.48), and ATV (2.39, 95% CI, 1.69–3.38). Within- and between-person variations in plasma and genital antiretroviral concentrations were observed. Low amounts of genital HIV-1 RNA (<50 copies/mL) were detected in 45% of women at 16% of visits. Genital HIV-1 DNA was detected in 70% of women at 35% of visits. Genital virus detection was associated with higher concentrations of mucosal leukocytes but not with genital antiretroviral concentrations, menstrual cycle phase, bacterial vaginosis, genital bleeding, or plasma virus detection. Conclusions. Standard doses of ART achieved higher genital than plasma concentrations across the menstrual cycle. Therapeutic ART suppresses genital virus shedding throughout the menstrual cycle, even in the presence of factors reported to increase virus shedding. PMID:24643223

    The management of benign and malignant neoplasms of the salivary glands requires precise knowledge of tumor histogenesis and classification as well as surgical skills. Pleomorphic adenoma and Whartin's tumor are the most frequent tumors in parotid glands while the probability for malignant tumors is higher in other glands, especially in sublingual and minor salivary glands. Those malignant salivary glands tumors are rare and necessitate multidisciplinar staging and management in close collaboration with the pathologist and the radiation oncologist.

    This review summarizes new treatments from the last seven years employed for the treatment of genital warts caused by human papillomavirus (HPV). Imquimod 3.75% is a new agent with fewer side effects and perhaps a better dosing schedule than imquimod 5%, but is not more effective. Sinecatechins/Polyphenon E 15%, a novel extract from green tea can be effective against genital warts but requires three times a day dosing and is not more effective than existing treatments; the treatment course is 12-16 weeks. Photodynamic therapy combined with other destructive modalities might increase the cure rate for genital warts. The quadrivalent vaccine against HPV 6, 11, 16, 18 is decreasing the incidence of warts in the western world but the evidence does not support vaccination as a treatment for those already infected by HPV. Hyperthermia and immunomodulators might be positive additions to the armamentarium of clinicians. In sum, there are new tools that physicians can use but none is really a great advance over what was available a decade ago. PMID:24011309

    Caecilians are a unique group of limbless burrowing amphibians with discontinuous distribution. Several caecilian species are viviparous, and all practice internal fertilization. In amniotic vertebrates the sperm undergo post-testicular physiological maturation when they are initiated into motility under the influence of an epididymal secretion. Further, during ejaculation mammalian sperm are suspended in a fluid secreted by the male accessory sex glands, viz., prostate gland and seminal vesicles. Caecilians lack comparable glands, but still practice internal fertilization. Uniquely, male caecilians retain the Mullerian ducts in the adults as a pair of functional glands. It has long been hypothesized, based on indirect evidence, that the Mullerian gland would be a male accessory sex gland, secreting a fluid in which sperm are suspended during ejaculation and which would also provide nutritional support to the ejaculated sperm. In the present study, the secretory material of the Mullerian gland of Uraeotyphlus narayani was mixed with sperm obtained from the testis, and the changes in motility were recorded. Uraeotyphlus narayani sperm possess a perforatorium of the acrosome proceeding deep into the endonuclear canal of the nucleus. The midpiece is characterized by closely applied centrioles, the anterior ends of the axoneme and axial fiber, and a mitochondrial sheath. The long tail has an undulating membrane on one side, supported by the axoneme and an axial fiber. The live sperm possess a mitochondrial vesicle, also known as the cytoplasmic droplet, anywhere along the head and the midpiece, as in anuran sperm, which is shed from sperm that have ceased motility. Uraeotyphlus narayani sperm are motile the moment they are released directly from the testis, indicating that the sperm do not require post-testicular physiological maturation.

  10. Hunting for eruption ages in accessory minerals

    2012-12-01

    A primary goal in geochronology is to provide precise and accurate ages for tephras that serve as chronostratigraphic markers for constraining the timing and rates of volcanism, sedimentation, climate change, and catastrophic events in Earth history. Zircon remains the most versatile accessory mineral for dating silicic tephras due to its common preservation in distal pyroclastic deposits, as well as the robustness of its U-Pb and U-series systems even after host materials have been hydrothermally altered or weathered. Countless studies document that zircon may be complexly zoned in age due to inheritance, contamination, recycling of antecrysts, protracted crystallization in long-lived magma reservoirs, or any combination of these. Other accessory minerals such as allanite or chevkinite can retain similar records of protracted crystallization. If the goal is to date the durations of magmatic crystallization, differentiation, and/or magma residence, then these protracted chronologies within and between accessory minerals are a blessing. However, if the goal is to date the timing of eruption with high precision, i.e., absolute ages with millennial-scale uncertainties, then this age zoning is a curse. Observations from ion microprobe 238U-230Th dating of Pleistocene zircon and allanite provide insight into the record of near-eruption crystallization in accessory minerals and serve as a guide for high-precision whole-crystal dating. Although imprecise relative to conventional techniques, ion probe analysis allows high-spatial resolution 238U-230Th dating that can document multi-millennial age distributions at the crystal scale. Analysis of unpolished rims and continuous depth profiling of zircon from small and large volume eruptions (e.g., Coso, Mono Craters, Yellowstone) reveals that the final several micrometers of crystallization often yield ages that are indistinguishable from associated eruption ages from the 40Ar/39Ar or (U-Th)/He methods. Using this approach, we

    Mammalian external genitals show sexual dimorphism [1, 2] and can change size and shape upon sexual arousal. Genitals feature prominently in the oldest pieces of figural art [3] and phallic depictions of penises informed psychoanalytic thought about sexuality [4, 5]. Despite this longstanding interest, the neural representations of genitals are still poorly understood [6]. In somatosensory cortex specifically, many studies did not detect any cortical representation of genitals [7-9]. Studies in humans debate whether genitals are represented displaced below the foot of the cortical body map [10-12] or whether they are represented somatotopically [13-15]. We wondered what a high-resolution mapping of genital representations might tell us about the sexual differentiation of the mammalian brain. We identified genital responses in rat somatosensory cortex in a region previously assigned as arm/leg cortex. Genital responses were more common in males than in females. Despite such response dimorphism, we observed a stunning anatomical monomorphism of cortical penis and clitoris input maps revealed by cytochrome-oxidase-staining of cortical layer 4. Genital representations were somatotopic and bilaterally symmetric, and their relative size increased markedly during puberty. Size, shape, and erect posture give the cortical penis representation a phallic appearance pointing to a role in sexually aroused states. Cortical genital neurons showed unusual multi-body-part responses and sexually dimorphic receptive fields. Specifically, genital neurons were co-activated by distant body regions, which are touched during mounting in the respective sex. Genital maps indicate a deep homology of penis and clitoris representations in line with a fundamentally bi-sexual layout [16] of the vertebrate brain. PMID:26725197

    Rapid and divergent evolution of male genital morphology is a conspicuous and general pattern across internally fertilizing animals. Rapid genital evolution is thought to be the result of sexual selection, and the role of natural selection in genital evolution remains controversial. However, natural and sexual selection are believed to act antagonistically on male genital form. We conducted an experimental evolution study to investigate the combined effects of natural and sexual selection on the genital-arch lobes of male Drosophila simulans. Replicate populations were forced to evolve under lifetime monogamy (relaxed sexual selection) or lifetime polyandry (elevated sexual selection) and two temperature regimes, 25°C (relaxed natural selection) or 27°C (elevated natural selection) in a fully factorial design. We found that natural and sexual selection plus their interaction caused genital evolution. Natural selection caused some aspects of genital form to evolve away from their sexually selected shape, whereas natural and sexual selection operated in the same direction for other shape components. Additionally, sexual and natural selection tended to favour larger genitals. Thus we find that the underlying selection driving genital evolution is complex, does not only involve sexual selection, and that natural selection and sexual selection do not always act antagonistically.

    1981-10-01

    Salivary gland imaging with 99mTc as pertechnetate provides functional information concerning trapping and excretion of the parotid and submandibular glands. Anatomic information gained often adds little to clinical evaluation. On the other hand, functional information may detect subclinical involvement, which correlates well with biopsy of the minor labial salivary glands. Salivary gland abnormalities in systemic disease such as sarcoidosis, rheumatoid arthritis, lupus erythematosus, and other collagenvascular disorders may be detected before they result in the clinical manifestaions of Sjoegren's syndrome. Such glands, after initially demonstrating increased trapping in the acute phase, tend to have decreased trapping and failure to discharge pertechnetate in response to an appropriate physiologic stimulus. Increased uptake of gallium-67 citrate often accompanies these findings. Inflammatory parotitis can be suspected when increased perfusion is evident on radionuclide angiography with any agent. The ability of the salivary gland image to detect and categorize mass lesions, which result in focal areas of diminished activity such as tumors, cysts, and most other masses, is disappointing, while its ability to detect and categorize Warthin's tumor, which concentrates pertechnetate, is much more valuable, although not specific.

  1. Mammary Gland Development

    PubMed Central

    Macias, Hector

    2012-01-01

    The mammary gland develops through several distinct stages. The first transpires in the embryo as the ectoderm forms a mammary line that resolves into placodes. Regulated by epithelial/mesenchymal interactions, the placodes descend into the underlying mesenchyme and produce the rudimentary ductal structure of the gland present at birth. Subsequent stages of development – pubertal growth, pregnancy, lactation and involution – occur postnatally under the regulation of hormones. Puberty initiates branching morphogenesis, which requires growth hormone and estrogen, as well as IGF1, to create a ductal tree that fills the fat pad. Upon pregnancy the combined actions of progesterone and prolactin generate alveoli, which secrete milk during lactation. Lack of demand for milk at weaning initiates the process of involution whereby the gland is remodeled back to its pre-pregnancy state. These processes require numerous signaling pathways that have distinct regulatory functions at different stages of gland development. Signaling pathways also regulate a specialized subpopulation of mammary stem cells that fuel the dramatic changes in the gland occurring with each pregnancy. Our knowledge of mammary gland development and mammary stem cell biology has significantly contributed to our understanding of breast cancer and has advanced the discovery of therapies to treat this disease.

    This study evaluated the ultrasound (US) features of 20 patients with MAGI and concomitant papilloma virus (HPV) infection compared to 20 patients with microbial (presence of Chlamydia trachomatis alone) MAGI and 20 patients with amicrobial (inflammatory) MAGI. Patients with HPV infection showed significantly (p < 0.05) higher total prostate, seminal vesicles, and epididymal US signs (18.0 ± 2.0) compared to the other 2 groups (12.0 ± 4.0 versus 10.0 ± 3.0, resp.). In addition, patients with MAGI and HPV had a higher prevalence of complicated forms of MAGI [prostatovesiculitis (PV) and prostate-vesiculo-epididymitis (PVE)] and a higher frequency of the fibrosclerotic variant compared to the other groups (70.0 ± 10.0% versus 48.0 ± 5.0% versus 15.0 ± 10.0%). Moreover, HPV infected patients had a higher number of US criteria suggestive for MAGI in the periurethral region of the prostate compared to the other groups. In particular, the patients showed a higher ratio between periurethral and lobar US criteria distribution (5.0 versus 0.5). Finally, the seminal fluid concentration of CD45pos leukocytes (2.0 ± 0.2 versus 1.3 ± 0.3 versus 1.0 ± 0.3 mil/mL) was significantly higher and sperm progressive motility was significantly lower in these patients compared to other groups.

    The lipid components of meibomian gland excreta were evaluated in rabbits after they received 2% topical epinephrine dropped into their eyes daily for a period of 6 months to a year to induce meibomian gland dysfunction (MGD). Changes were compared to excreta obtained from seven age-matched, untreated control rabbits. Comparison of the lipids from MGD lids with lipids obtained from control rabbits revealed, for clinically evident MGD, a marked increase in the lipids that are uniquely characteristic of epidermal tissue. These epidermal lipids are free sterols (large amounts) and a group of seven types of ceramides. The data are consistent with the hypothesis that the initiating factor of rabbit MGD is hyperkeratinization of the ductal epithelia. For clinically apparent MGD some hydrolysis of the sterol esters of the meibomian gland lipids also seems to have occurred. This was evidenced by the formation of an 8-fold increase in a cluster of anteiso fatty acids with chain lengths longer than C20 in the free fatty acid fraction. This group of free fatty acids was the same as the acids esterified to the sterol esters. We could detect no change in the lipid excreta obtained from rabbits that developed only subclinical MGD, consisting of orifice plugging and dilation of the duct.

    Gracilis and semitendinosus tendons are commonly used as grafts in ligamentous reconstruction. Awareness of accessory bands of these tendons is essential in preventing inadvertent diversion of the tendon harvester into the main tendon resulting in premature tendon amputation and inadequate tendon graft. The aim of this study was to describe the characteristics of these accessory bands. Twenty five patients undergoing arthroscopic anterior cruciate ligament reconstruction using hamstring tendons were included. The number of accessory bands and distance of the most proximal band from the distal periosteal insertion point on the tibial crest was recorded for both gracilis and semitendinosus. In most cases gracilis had two accessory bands; the average distance of the most proximal band from the tibial crest insertion being 5.1 cm. Semitendinosus had three bands in most cases, the average distance of the most proximal band from the tibial crest insertion being 8.1 cm. Five (20%) semitendinosus but no gracilis tendons had an accessory band originating greater than 10 cm from the tibial crest insertion. Semitendinosus had more accessory bands compared to gracilis. A significant proportion (20%) of semitendinosus and none of the gracilis tendons had bands originating greater than 10 cm proximal to the tibial crest insertion. This knowledge about the accessory bands of the hamstrings can guide toward safe harvesting of these tendons.

The magnetic resonance imaging and arthroscopic appearance of the accessory head of the biceps brachii has been recently described. This series demonstrates the sonographic appearance of the accessory head of the biceps brachii in the bicipital groove. It is an asymptomatic, flat, echogenic structure with average measurements of 7.7 × 1.2 mm in cross section. Knowledge of this anatomic variant can avoid the misdiagnosis of a longitudinal split tear and improve the accuracy of sonography.

    Accessory spleens were sought in 28 patients who had undergone splenectomy for chronic idiopathic thrombocytopenic purpura (ITP), using a variety of techniques. Abdominal scintigraphy with autologous erythrocytes labeled with Tc-99m and opsonized with anit-D IgG (radioimmune method) proved to be most useful, clearly demonstrating one or more accessory spleens in 12 cases (43%). Computed tomography (CT) was also helpful. Four out of five patients demonstrated an increased platelet count following surgery, the effectiveness of which was illustrated by the radioimmune scan. Patients who have had splenectomy for chronic ITP should be scanned using radioimmune techniques and CT to determine whether an accessory spleen is present.

They appear in genome as a result of DNA bases damages caused by various and numerous environmental factors eg. ultraviolet light, ionic radiation, toxins and also endogenic substances, for example estrogens. It is believed that the creation of DNA adducts is a necessary but insufficient process for the neoplastic transformation of the cell. The following review presents concise knowledge about the DNA adducts creation and their sequels served in healthy and cancerous tissues of the female genital organs, on the base of the available data.

    In an effort to develop guidelines for the management of acute genital injuries in prepubertal girls, we categorized 32 cases by the object that allegedly caused the injury: straddle injuries, nonpenetrating injuries, penetrating injuries, and torque injuries. Using these categories and the anatomic features of symmetry and/or hymenal transection, we determined that the most dangerous injuries were the penetrating injuries that were symmetric and transected the hymen; in this series these were all the result of sexual assault. Future studies are needed to determine if these unique injuries can be managed with less physical and psychosocial trauma to the young patient. PMID:1595800

    Female genital mutilation, traditionally known as female circumcision, is a surgically unnecessary modification of the female genitalia, practiced in nations in Africa, the Arab Peninsula, among some communities in Asia, and among immigrants and refugees from these areas who have settled in other areas. The practice is known across socio-economic classes and among many different ethnic and cultural groups, including Christians, Muslims, Jews, and followers of indigenous African religions. As people from these areas immigrate to North America, health care professionals need to understand the important aspects of this growing problem, including management of complications, cultural attitudes, and sensitivities.

    Female genital mutilation (FGM) is an unusual condition for our country. However, an increase in FGM in future days can be predicted with the increasing numbers of exchange students coming from African countries, migration of refugees and socioeconomic relations with the African countries. We want to share our experience of two FGM victims admitted to our clinic with the request of reconstructive vulvar surgery before their marriage. Both women had WHO Type III FGM. Physical examination findings and surgical reconstruction techniques were presented. PMID:27274899

  12. The evolution of sweat glands

    1991-09-01

    Mammals have two kinds of sweat glands, apocrine and eccrine, which provide for thermal cooling. In this paper we describe the distribution and characteristics of these glands in selected mammals, especially primates, and reject the suggested development of the eccrine gland from the apocrine gland during the Tertiary geological period. The evidence strongly suggests that the two glands, depending on the presence or absence of fur, have equal and similar functions among mammals; apocrine glands are not primitive. However, there is a unique and remarkable thermal eccrine system in humans; we suggest that this system evolved in concert with bipedalism and a smooth hairless skin.

    Sebaceous lymphadenoma is a rare primary tumour of the salivary gland, benign in nature arising from differentiated Sebaceous glands and cells in the salivary gland. Most of the tumours are seen in the parotid gland and very rarely in the submandibular gland. Herein a case of sebaceous lymphadenoma is reported in a 45 years old female with a swelling in the submandibular region. Histopathological study after surgical excision showed islands of sebaceous epithelial cells with dense collections of lymphoid cells in stroma and a diagnosis of sebaceous lymphadenoma of submandibular gland was made.

    Primary lymphomas arising in salivary glands are very uncommon. The histologic classification of 40 cases of lymphomas in salivary gland tissue submitted to the British Salivary Gland Tumour Panel is reported, and, for 30 of the patients for whom adequate information was available, the clinical presentation, management, and outcome have been analyzed. Lymphomas in salivary glands represented 1.7% of all reported salivary neoplasms. The majority developed in the parotid glands of patients aged between 50 and 70 years. Only four cases gave a premorbid history compatible with sicca syndrome. In this series, non-Hodgkin's lymphomas predominated; 23 were Grade I, and 13 were Grade II. Treatment regimens were not uniform, but are outlined. Survival ranged from 5 to 111 months. Median survival for the group was 49 months. Prognosis was not influenced by the clinical stage of disease at presentation. Four cases of lymphoma arising in benign lymphoepithelial lesions are included. None had clinical symptoms of sicca complex. Prognosis for this group was found to be as favorable as the others.

    Medical therapy of genital condylomatosis seems to be the most rational strategy, since this pathology is characterised by highly frequent recurrences after destructive physical therapy alone. Successful therapy of female genital condylomatosis with methisoprinol (Viruxan), administered as ointment and/or vaginal ovules is reported. The drug proved to be efficient both in curing this viral infection and preventing its recurrences. PMID:2472583

  5. Accessory proteins for heterotrimeric G-proteins in the kidney

    PubMed Central

    Park, Frank

    2015-01-01

    Heterotrimeric G-proteins play a fundamentally important role in regulating signal transduction pathways in the kidney. Accessory proteins are being identified as direct binding partners for heterotrimeric G-protein α or βγ subunits to promote more diverse mechanisms by which G-protein signaling is controlled. In some instances, accessory proteins can modulate the signaling magnitude, localization, and duration following the activation of cell membrane-associated receptors. Alternatively, accessory proteins complexed with their G-protein α or βγ subunits can promote non-canonical models of signaling activity within the cell. In this review, we will highlight the expression profile, localization and functional importance of these newly identified accessory proteins to control the function of select G-protein subunits under normal and various disease conditions observed in the kidney.

    Since three-dimensional computed tomography was developed, many researchers have described accessory mental foramina. The anatomical and radiological findings have been discussed, but details of accessory mental nerves (AMNs) have only been researched in a small number of anatomical and clinical cases. For this article, we reviewed the literature relating to accessory mental foramina (AMFs) and nerves to clarify aspects important for clinical situations. The review showed that the distribution pattern of the AMN can differ according to the position of the accessory mental foramen, and the reported incidence of AMFs differs among observation methods. A review of clinical cases also revealed that injury to large AMF can result in paresthesia. This investigation did not reveal all aspects of AMNs and AMFs, but will be useful for diagnosis and treatment by many dentists and oral and maxillofacial surgeons.

  12. Salivary gland disorders.

    PubMed

    Wilson, Kevin F; Meier, Jeremy D; Ward, P Daniel

    2014-06-01

    Salivary gland disorders include inflammatory, bacterial, viral, and neoplastic etiologies. The presentation can be acute, recurrent, or chronic. Acute suppurative sialadenitis presents as rapid-onset pain and swelling and is treated with antibiotics, salivary massage, hydration, and sialagogues such as lemon drops or vitamin C lozenges. Viral etiologies include mumps and human immunodeficiency virus, and treatment is directed at the underlying disease. Recurrent or chronic sialadenitis is more likely to be inflammatory than infectious; examples include recurrent parotitis of childhood and sialolithiasis. Inflammation is commonly caused by an obstruction such as a stone or duct stricture. Management is directed at relieving the obstruction. Benign and malignant tumors can occur in the salivary glands and usually present as a painless solitary neck mass. Diagnosis is made by imaging (e.g., ultrasonography, computed tomography, magnetic resonance imaging) and biopsy (initially with fine-needle aspiration). Overall, most salivary gland tumors are benign and can be treated with surgical excision.

    Salivary gland myoepithelial carcinoma (MC) or malignant myoepithelioma is a rare entity. MC usually presents as a slow-growing painless mass arising in the parotid gland, but may involve other salivary glands. This tumour may be particularly locally aggressive, but its clinical and biological features are not yet fully understood. MC may arise from pre-existing benign lesions, such as pleomorphic adenomas or benign myoepitheliomas, or may arise de novo. It usually affects patients over 50 years old, with no gender preference. Because it is often asymptomatic, the presentation and diagnosis can be delayed by months, even years. The current WHO classification considers MC to be an intermediate- to high-grade malignancy. Other published data suggest it is likely to be a high-grade neoplasm, consistent with its aggressive behaviour. Its epidemiology, histopathological features, immunohistochemical profile, clinical behaviour and optimal management are not well understood. Following review of the current literature we aim to address these.

    1996-12-01

    A national survey of investigators caring for human immunodeficiency virus (HIV)-infected women was undertaken to describe the clinical presentation of idiopathic genital ulcer disease. Patients with negative syphilis and herpes simplex testing and/or negative genital ulcer biopsy were included in this study. Study participants (n = 29) were generally severely immunocompromised (median CD4 cell count was 50/mm3, and 68% had an acquired immunodeficiency syndrome [AIDS]-defining opportunistic process). Thirty-seven percent had coexistent oral ulcers and 19% had their genital ulcer progress to fistula formation (four rectovaginal and one vaginal-perineal). There was generally a favorable response to topical, systemic, and intralesional steroid treatment. This study suggests that idiopathic or probable aphthous genital ulcers in women have similar clinical characteristics to aphthous oroesophageal ulcers. Although infrequent, these genital ulcers can cause severe morbidity. Further research is warranted to better define the pathophysiology and optimal management.

    2004-01-01

    Three women with large, mutilating genital ulcers of long duration, destroying almost the lower half of the external genitalia, are reported. They had a history of recurrent oral ulcers as well. All patients had been diagnosed as having 'genital ulcer syndrome' in the past and had been treated with antimicrobials. Histopathology of the biopsy from the margin of the ulcer revealed features of leukocytoclastic vasculitis. Considering the history, clinical features and histology, a diagnosis of bipolar aphthosis was made in all patients. All patients responded well to immunosuppressive therapy. The cases are reported because of the presence of genital ulcers of an unusually large size, mutilating character and their close similarity to genital ulcers due to sexually transmitted diseases, especially genital herpes and donovanosis.

    PubMed

    2013-07-01

    Hair tourniquet syndrome has been recognized as a medical entity since the 1600 s. Appendages develop acute ischemia from tightening of hair strands circumferentially wrapped around them. Most commonly affected sites are fingers, toes, and penis, but limited reports have described involvement of the female genitalia. Although hair strangulation involving the labia minora or clitoris has been described, it typically occurs in young children. We present a case of an adolescent girl with a labial appendage hair tourniquet resulting from a previous unrepaired genital laceration. This is one of the oldest patients in whom a genital hair tourniquet has been reported, as well as description of a posttraumatic genital appendage. Genital hair tourniquets are medical emergencies that require prompt diagnosis and treatment to avoid tissue necrosis and possible amputation. Genital trauma in general requires surgical evaluation.

  17. A review of famciclovir in the management of genital herpes.

    1998-01-01

    The frequent occurrence of genital herpes continues to be a serious clinical problem. Although not life threatening, the physical symptoms of the disease, and the ensuing psychosocial complications, can be overwhelming to patients. The life cycle of the herpes simplex virus is complex, comprising multiple stages. Following infection, the virus establishes life-long latency in its host and can reactivate at any time as a recurrent infection. Successful management of genital herpes simplex infections involves patient education and psychological support, as well as antiviral agents. The antiviral agent famciclovir has been shown to shorten the course and decrease the severity of episodes of recurrent genital herpes. In addition, famciclovir has been shown to be effective in suppressing recurrent genital herpes. A review of the clinical experience with famciclovir in the treatment of genital herpes is presented.

    Deutsch, U.; Fioroni, P.

    1996-03-01

    Experiments were performed with the mesogastropod Littorina littorea on Helgoland, in Roscoff, and in the laboratory in order to evaluate the reaction of the female genital system to TBT, an environmental toxicant. The snails were either injected with 50 or 100 ng tributyltin (TBT) soluted in ethanol or exposed to artificial sea water treated with 5, 50, 100, and 200 ng TBT/l, and 33 ng testosterone/l. The duration of the experiments was either four or eight weeks. None of the analysed female L. littorea showed signs of imposex. Compared to results for the control groups, the size of the female glandular complex was significantly reduced if the pre-experimental toxication was already high, as is the case in snails collected around Helgoland. TBT-related gland complex reduction occurs also in female L. littorea from other sampling sites. In addition, injection of ethanol also causes a decrease in gland size. The experimental results demonstrate that the distal female genital system responds with significantly lower sensitivity to TBT than that of other prosobranchs. This behaviour is ascribed to the lack of an androgen receptor at the ovipositor. The results further strengthen the case of the extreme rarity of imposex described for female L. littorea in natural habitats. However, strong TBT-toxication may affect L. littorea populations significantly because of increasing masculinization of the females, which reduces reproduction ability.

    1991-03-15

    Langerhans cell histiocytosis (LCH) of the female genital tract is rare. Four new cases are reported, and there is a review of the 38 cases in the literature. This disease may involve the vulva, vagina, cervix, endometrium, and ovary. Four distinct patient groups, segregated on the basis of initial presentation and subsequent anatomic extent of disease, were categorized as follows: (1) "pure" genital LCH, (2) genital LCH with subsequent multi-organ involvement, (3) oral or cutaneous LCH with subsequent genital and multi-organ involvement, and (4) diabetes insipidus with subsequent genital and multi-organ disease. Although involvement of the genital tract can occur at any age, it is most common in young adulthood. Clinically, LCH may mimic either primary neoplasia or various inflammatory lesions; the major pathologic differential diagnosis is venereal and other inflammatory diseases. The pure genital form may have a distinct nosologic position in the spectrum of LCH similar to the "pure," self-limited cutaneous histiocytosis seen in infants. There is no correlation between histologic findings and the outcome of the genital lesions. There is also no correlation between clinical presentation and/or the extent of involvement and outcome of genital lesions; complete regression, partial improvement, persistent lesions, and recurrences were seen in all four groups of patients. The treatment of genital LCH is not well defined and is highly individualized. Therapy has included surgery, radiation, topical corticosteroids, topical nitrogen mustard, systemic chemotherapy, and combination therapy; mixed results were obtained with all treatment modalities. Although no modality has been shown to yield a superior outcome, complete surgical excision is advocated as initial therapy.

    2016-01-01

    Female genital mutilation (FGM), otherwise known as female genital cutting (FGC), is currently very topical and has become a significant global political issue. The impact of FGM on the lives of women and girls is enormous, as it often affects both their psychology and physical being. Among the complications that are often under-reported and not always acknowledged is female sexual dysfunction (FSD). FSD presents with a complex of symptoms including lack of libido, arousability and orgasm. This often occurs in tandem with chronic urogenital pain and anatomical disruption due to perineal scarring.To treat FSD in FGM each woman needs specifically directed holistic care, geared to her individual case. This may include psychological support, physiotherapy and, on occasion, reconstructive surgery. In many cases the situation is complicated by symptoms of chronic pelvic pain, which can make treatment increasingly difficult as this issue needs a defined multidisciplinary approach for its effective management in its own right. The problems suffered by women with FGM are wholly preventable, as the practice need not happen. The current global momentum to address the social, cultural, economic and medical issues of FGM is being supported by communities, governments, non-governmental agencies (NGOs) and healthcare providers. It is only by working together that the practice can be abolished and women and girls may be free from this practice and its associated consequences. PMID:26759415

    Carcinosarcoma, also known as mixed mesodermal tumor or malignant mixed Mullerian tumor (MMMT) is a pathological entity combining a sarcomatous and a carcinomatous component. Found in thoracic, digestive, genitourinary, liver or skin locations, the most common location is the female genital tract. In gynecological tumors, carcinosarcoma accounts for about 2-5% of endometrial cancers, and 1% of ovarian cancers. To date, there is no consensus on the therapeutic strategy. It relies mostly on maximum cytoreductive surgery. Adjuvant therapy remains controversial, and few prospective studies investigating its interest. Retrospective studies show the benefits of adjuvant chemotherapy based on platinum in most cases. Radiation therapy has a place in the adjuvant situations of endometrial and cervical carcinosarcoma. A more detailed pathological knowledge, and the use of targeted therapies may be promising in this histological subtype whose prognosis remains very poor. The objective of this study is to present the main principles of carcinosarcoma management in female genital tracts, describing pathological and prognostic features at the same time.

  3. Therapeutic management of cutaneous and genital warts.

    PubMed

    Ockenfels, Hans Michael

    2016-09-01

    During their lifetime, at least 10 % of the population will be infected by human papillomaviruses (HPV), clinically characterized by the formation of cutaneous or genital warts. Although warts are ubiquitous, there are no defined treatments. Especially in the first six months, warts frequently resolve without therapeutic intervention. This complicates the interpretation of study data, given that many studies do not differentiate between newly infected patients and those with infections that have persisted for a long time. Similarly, most studies do not take location, size, and thickness of lesions into account, either. The objective of the present review article is to analyze the study data currently available, taking into consideration both subtypes and locations - factors exceedingly crucial in clinical practice. In particular, the distinction between new-onset and chronic recalcitrant warts is reflected in a therapeutic algorithm. In the case of genital warts, the algorithm is more clearly determined by the extent of the area affected rather than the longevity of lesions. In immunocompetent individuals, any therapeutic intervention must be aimed at achieving complete resolution. PMID:27607030

  4. An unusual type of secretory cell in the ventral pedal gland of the gastropod mollusc Buccinum undatum L.

    PubMed

    Price, N R; Hunt, S

    1976-01-01

    The ventral pedal gland in the foot of the mature female whelk Buccinum undatum L. consists of a shallow pouch containing a layer of elongated cells which partially penetrate a basement membrane overlying layers of smooth muscle. This glandular epithelium contains acid mucopolysaccharide cells, ciliated and interstitial cells as well as the upper part of a new type of subepidermal gland cell. These gland cells consist of an elongated extracellular tubular duct formed by an invagination of the cell membrane and lined by numerous microvilli. Into this duct are discharged packets of a densely staining secretion. The secretion packets are produced in Golgi regions around the nuclei of the cells and are passed up through the cell to the base of the duct through or along an extensive assemblage of microtubules. The secretion packets show organized internal structure and may contain aromatic aldehydes and protein associated with the sclerotization of the egg capsules, which pass through the gland after leaving the genital tract.

    Salivary glands are the first organs of digestion secreting their digestive juices into the oral cavity. Parotid, submandibular, and sublingual glands are the major paired salivary glands in the decreasing order of their size. In addition, multiple small minor salivary glands are noted randomly distributed in the upper aerodigestive tract, including paranasal sinuses and parapharyngeal spaces. The imaging is directed to the major salivary glands. Commonly used imaging methods include plain radiography and conventional sialography. Recently, high-resolution ultrasonography (HRUS) is being increasingly used for targeted salivary gland imaging. However, the advent of cross-sectional imaging techniques such as computed tomography (CT) and magnetic resonance imaging (MRI) have revolutionized the imaging of salivary glands. This article illustrates the role of imaging in evaluating the variegated disease pattern of the major salivary glands. PMID:23833425

    CT and MRI have greatly facilitated evaluation of pathology of the three pairs of major salivary glands and the hundreds of minor salivary glands. Imaging can frequently offer a specific histological diagnosis for benign and malignant neoplasms of the parotid, submandibular, and sublingual glands. Obstruction, infection, autoimmune processes, and congenital anomalies also are readily diagnosed. CT and MRI studies assess the anatomic extent of minor salivary gland neoplasms. Sialography continues to provide useful information about intrinsic abnormalities of the parotid and submandibular ducts.

    Vitiligo has a major effect on sexual health because of the disfiguring skin lesions affecting self-image and self-esteem. However, this topic has not explored. This article aimed to assess the effect of vitiligo on genital self-image, sexual function, and quality of life in female patients. This cross-sectional study included 50 sexually active women with vitiligo and 25 women without vitiligo. All participants subjected to full history taking and examination. Extent of vitiligo was assessed with the Vitiligo Area Scoring Index score, sexual function with the Female Sexual Function Index, genital self-image with Female Genital Self-Image Score and quality of life with the Dermatology Life Quality Index questionnaires. The main outcome measures were correlation between Vitiligo Area Scoring Index, Female Genital Self-Image Score, Female Sexual Function Index, and Dermatology Life Quality Index domains was determined using t test and Pearson correlation. This study revealed a negative correlation between the Vitiligo Area Scoring Index score and sexual satisfaction. Vitiligo Area Scoring Index and Dermatology Life Quality Index score was significantly correlated with Arabic Version of the Female Genital Self-Image Score alone and with Arabic Version of the Female Sexual Functioning Index alone and with both the Arabic Version of the Female Genital Self-Image Score and the Arabic Version of the Female Sexual Functioning Index (p <.05). Sexual and psychological assessment of patients with vitiligo is imperative to improve outcomes and increase patients' compliance with treatment.

    Hypertrophic suprarenal gland is an anomaly which can lead to serious complications during adrenalectomy under endoscopy because of abnormal veins of the retroperitoneum. The authors report a rare dissection of a male which presented with this anomaly in a case of homolateral renal agenesis, highlighting this left pseudorenal vein. No abnormality of the genital tract was found. The anatomic features, associated syndromes, implications for endoscopic surgery are outlined and embryologic considerations and discussed.

    In the case of the thymus gland, the most common indications for resection are myasthenia gravis or thymoma. The consistency and appearance of the thymus gland make it difficult at times to discern from mediastinal fatty tissues. Having a clear understanding of the anatomy and the relationship of the gland to adjacent structures is important.

    PAX8 and PAX2 are cell-lineage-specific transcription factors that are essential for the development of Wolffian and Müllerian ducts and have recently emerged as specific diagnostic markers for tumors of renal or Müllerian origin. Little is known about their expression in the Wolffian duct-derived human male genital tract. We report our findings of PAX8 and PAX2 expression in the epithelium of the normal male genital tract and in epithelial tumors derived therefrom using immunohistochemistry (IHC). We found that PAX8 and PAX2 were expressed in the epithelium of the male genital tract from the rete testis to the ejaculatory duct. Rare glands in the prostatic central zone, a tissue of purported Wolffian duct origin, were focally positive for PAX2, but no PAX8 was detected in this area, a finding that may warrant further study. We found diffuse expression of PAX8 and PAX2 in 1 case each of serous cystadenoma of the epididymis, carcinoma of the rete testis, Wolffian adnexal tumor of the seminal vesicle, and endometrioid carcinoma of the seminal vesicle. Neither PAX8 nor PAX2 was detected in the seminiferous tubules and interstitium of the normal testis, nor in Leydig cell tumors (n=6), Sertoli cell tumors (n=2), or 48 of 49 germ cell tumors. One pediatric yolk sac tumor showed focal and weak staining for PAX8. Tumors of mesothelial origin, that is, adenomatoid tumors (n=3) and peritoneal malignant mesotheliomas (n=37) in men, were negative for PAX2 and PAX8. Neither PAX2 nor PAX8 was present in other areas of the prostate. Expression of PAX8 and PAX2 in these primary epithelial neoplasms of the male genital tract is due to their histogenetic relationship with Wolffian or Müllerian ducts. PAX8 and PAX2 IHC may facilitate the diagnosis of these tumors and should be included in the differential diagnostic IHC panel.

    2012-05-01

    Meibomian gland dysfunction (MGD) is a chronic disease, usually caused by obstruction of the secretory Meibomian glands. The subsequent reduction of gland secretion results in a decreased amount of lipids in the tear film. This results in a faster evaporation of the tear film and thus an evaporative dry eye. MGD alone is responsible for about 60% of all cases in combination with aqueous deficiency for a further 20% of dry eyes. While in Europe up to 20% of the population are suffering from MDD, this is true in Asia for over 60% of the population. MGD is more common in women and it incidence increases with age. It is influenced by the hormonal status as well as chemical and mechanical noxious stimuli. Additional risk factors include various skin diseases such as rosacea, acne or atopy. To diagnose MGD, particular attention should be paid to changes in the lid margin such as plugging or pouting of the ducts, thickening and telangiectasia. However, most important is the diagnostic expression of the glands. At first it should be assessed whether secretion can be caused by pressure to the eyelid against the globe and secondly the quality of the expressed secretions should be evaluated. MGD should be treated according to the severity of the disease. While in mild stages instructions for lid margin hygiene, warming and massage in combination with artificial tears might be sufficient, in more severe stages oral tetracyclin derivatives and anti-inflammatory eye drops such as steroids or CSA are necessary for successful treatment.

    According to the P.N.A., the N.A.J. and some scholars, the sublingual gland has the ductus sublingualis major and ductus sublinguales minores. This means that the gland is a polystomatic gland. We intended to determine whether the so-called polystomatic gland exists or not. 1. According to the P.N.A., the N.A.J. and some scholars, the gl. sublingualis has the ductus sublingualis major and ductus sublinguales minores. This means the gland is a polystomatic gland. However, the formation of one gland with plural excretory ducts is embryologically impossible, in other words, the polystomatic gland does not exist. 2. Many scholars described that the gl. sublingualis was composed of the gl. sublingualis major and g11. sublinguales minores. However, they are completely different kinds of glands. Accordingly, we suggest the terms for these glands: the g1. sublingualis and its ductus sublingualis ("major" is useless), the g11. sublinguales minores and their ductus sublinguales minores. 3. The N.A.V.J. and some scholars use the term g1. sublingualis polystomatica or parvicanalaris. However, this is a group of a number of independent glands each of which has its own excretory duct. Such a gland should not be regarded as a single gland. We suggest that the term g11. sublinguales minores and their excretory ducts should be replaced with the term the ductus sublinguales minores. 4. The g1. lingualis anterior, g1. retromolaris and g1. lacrimalis are not single glands but a group of several independent glands each of which has its own excretory duct. Accordingly, they should be termed the g11. linguales anteriores, g11. retromolares and g11. lacrimales such as the g11. labiales, g11. buccales and g11. palatinae.

    The rapidly evolving and often extraordinarily complex appearance of male genital morphology of internally fertilizing animals has been recognized for centuries. Postcopulatory sexual selection is regarded as the likely evolutionary engine of this diversity, but direct support for this hypothesis is limited. We used two complementary approaches, evolution through artificial selection and microscale laser surgery, to experimentally manipulate genital morphology in an insect model system. We then assessed the competitive fertilization success of these phenotypically manipulated males and studied the fate of their ejaculate in females using high-resolution radioisotopic labeling of ejaculates. Males with longer genital spines were more successful in gaining fertilizations, providing experimental evidence that male genital morphology influences success in postcopulatory reproductive competition. Furthermore, a larger proportion of the ejaculate moved from the reproductive tract into the female body following mating with males with longer spines, suggesting that genital spines increase the rate at which seminal fluid passes into the female hemolymph. Our results show that genital morphology affects male competitive fertilization success and imply that sexual selection on genital morphology may be mediated in part through seminal fluid.

    Non-Hodgkin Lymphomas (NHL) are a separate group of blood diseases, which includes all types of lymphomas, without Hodgkin lymphomas. The incidence of NHL in the female genital system is 0.5% of all the NHL. They develop in the female genital organs primary or affect them secondary. Secondary development of the genital non-Hodgkin's lymphoma we have when the biopsy of a lymph node that precedes the diagnosis of the disease is before the development of a genital tumor or we can find a genital tumor--along with simultaneous involvement of the lymph nodes or extra genital authority. We present a clinical case of 56 years patient with non-Hodgkin's lymphoma with secondary genital involvement. From ultrasonography, computed axial tomography and Tu markers that were maiden we have suspicion for ovarian tumor with mechanical pressure over pyelocalix system due to left hidroureter and left hydronephrosis II degree. That was the only reason for urgent surgical treatment with intraoperative histologic diagnosis of NHL. The postoperative chemotherapy in combination with surgical treatment in our case had a good and long-lasting disease survivor effect. One year after the operation and the chemotherapy in the patient, there is no evidence of relapse.

    To examine the risks of genital herpes and antiherpes treatment during pregnancy in relation to preterm delivery (PTD), we conducted a multicenter, member-based cohort study within 4 Kaiser Permanente regions: northern and southern California, Colorado, and Georgia. The study included 662,913 mother-newborn pairs from 1997 to 2010. Pregnant women were classified into 3 groups based on genital herpes diagnosis and treatment: genital herpes without treatment, genital herpes with antiherpes treatment, and no herpes diagnosis or treatment (unexposed controls). After controlling for potential confounders, we found that compared with being unexposed, having untreated genital herpes during first or second trimester was associated with more than double the risk of PTD (odds ratio (OR) = 2.23, 95% confidence interval (CI): 1.80, 2.76). The association was stronger for PTD due to premature rupture of membrane (OR = 3.57, 95% CI: 2.53, 5.06) and for early PTD (≤35 weeks gestation) (OR = 2.87, 95% CI: 2.22, 3.71). In contrast, undergoing antiherpes treatment during pregnancy was associated with a lower risk of PTD compared with not being treated, and the PTD risk was similar to that observed in the unexposed controls (OR = 1.11, 95% CI: 0.89, 1.38). The present study revealed increased risk of PTD associated with genital herpes infection if left untreated and a potential benefit of antiherpes medications in mitigating the effect of genital herpes infection on the risk of PTD.

    Persistent genital arousal disorder is a rare condition among women characterized by unwanted and intrusive sexual arousal that can persist for an extended period of time and unrelated to sexual desire or sexual stimuli. Since its first documentation in 2001, numerous studies have been dedicated to investigate its specifics. The persistent genital arousal occurs in the absence of sexual interest and fantasies and it causes excessive psychological suffering. Masturbation, spontaneous orgasm or sexual intercourse can offer only a temporary relief. Researches provide a limited insight into the characteristics of persistent genital arousal disorder. This paper presents a case and summarizes the scientific findings on prevalence, etiology and treatment perspectives. PMID:25845321

    Streptozotocin (STZ) is a naturally occurring compound isolated from Streptomyces achromogens. It is used extensively for inducing diabetes in experimental animals. Diabetes mellitus is known to have proven adverse effects on male sexual organs and their reproductive functions. The atrophy of prostate gland and other organs of the genitourinary tract were observed in experimental diabetic animals. STZ exhibits a structural resemblance to D-glucose due to the presence of sugar moiety in its structure. Pancreatic {beta}-cells mainly contain GLUT1 and GLUT2 glucose transporters. Possibly due to structural resemblance, STZ and D-glucose, share a common recognition site for entry into the {beta}-cells. The objective of the present study is to evaluate the effect of D-glucose on STZ-induced toxicity in accessory sex organs of male rats. Animals were kept on overnight fasting. One group received vehicle and served as negative control, while all other groups were given STZ (45 mg/kg). Animals that received only STZ served as positive control. The effect of D-glucose was studied on STZ treated animals with different dosage of D-glucose (250, 500, 1000 and 2000 mg/kg). Restoration of body weight, plasma glucose and plasma insulin was evident only at 1000 and 2000 mg/kg of D-glucose. The protective effect of D-glucose is evident only when it is administered simultaneously with STZ. In the present investigation, we report that simultaneous administration of D-glucose along with STZ ameliorates STZ-induced toxicity. This is evident from the restoration of accessory sex organ's weight, cellular morphology as well as insulin level.

  2. Accessory costs of seed production and the evolution of angiosperms.

    PubMed

    Lord, Janice M; Westoby, Mark

    2012-01-01

    Accessory costs of reproduction frequently equal or exceed direct investment in offspring, and can limit the evolution of small offspring sizes. Early angiosperms had minimum seed sizes, an order of magnitude smaller than their contemporaries. It has been proposed that changes to reproductive features at the base of the angiosperm clade reduced accessory costs thus removing the fitness disadvantage of small seeds. We measured accessory costs of reproduction in 25 extant gymnosperms and angiosperms, to test whether angiosperms can produce small seeds more economically than gymnosperms. Total accessory costs scaled isometrically to seed mass for angiosperms but less than isometrically for gymnosperms, so that smaller seeds were proportionally more expensive for gymnosperms to produce. In particular, costs of abortions and packaging structures were significantly higher in gymnosperms. Also, the relationship between seed:ovule ratio and seed size was negative in angiosperms but positive in gymnosperms. We argue that the carpel was a key evolutionary innovation reducing accessory costs in angiosperms by allowing sporophytic control of pre- and postzygotic mate selection and timing of resource allocation. The resulting reduction in costs of aborting unfertilized ovules or genetically inferior embryos would have lowered total reproductive costs enabling early angiosperms to evolve small seed sizes and short generation times.

    A study was conducted on labial salivary gland tumors from four oral pathology laboratories. Of the 103 identified tumors, 87 (84.5%) were from the upper lip, whereas 16 (15.5%) were from the lower lip. Of the 87 upper lip tumors, 80 (92.0%) were benign. Forty-three of these were monomorphic adenomas and 37 were pleomorphic adenomas. Seven malignant tumors of the upper lip were as follows: four adenoid cystic carcinomas, two acinic cell carcinomas, and one adenocarcinoma. Of the 16 lower lip tumors, 15 (93.8%) were malignant. Thirteen of these were mucoepidermoid carcinomas and two were acinic cell carcinomas. The only benign lower lip tumor was an intraductal papilloma. These results confirm the findings of previous investigations, showing that minor salivary gland tumors are much more common in the upper lip than the lower lip, but that lower lip tumors are more likely to be malignant.

    2014-01-01

    Up to 60 different proteins are recruited to the site of clathrin-mediated endocytosis in an ordered sequence. These accessory proteins have roles during all the different stages of clathrin-mediated endocytosis. First, they participate in the initiation of the endocytic event, thereby determining when and where endocytic vesicles are made; later they are involved in the maturation of the clathrin coat, recruitment of specific cargo molecules, bending of the membrane, and finally in scission and uncoating of the nascent vesicle. In addition, many of the accessory components are involved in regulating and coupling the actin cytoskeleton to the endocytic membrane. We will discuss the different accessory components and their various roles. Most of the data comes from studies performed with cultured mammalian cells or yeast cells. The process of endocytosis is well conserved between these different organisms, but there are also many interesting differences that may shed light on the mechanistic principles of endocytosis.

    The purpose of genital examination (GE) during the Pre-participation Physical Examination (PPE) is to identify the state of maturity, and rule out any genital pathology. To describe genital anomalies (GA) and estimate the awareness of GE in young football players. A descriptive, cross-sectional study was conducted in 280 elite football players from the results of PPE over two seasons. There was a detection rate of 5.4% GA, with varicocele being 3.2%, and of which only 13% were aware of their condition. Although this study shows a low incidence of genital abnormality in the study population, only 13% were aware of the GE prior to assessment. These findings demonstrate a low incidence of GA in this population. While GE is recommended during PPE, it is not a routine practice performed by family doctors or sports medicine specialists. This article attempts to raise awareness of the importance of GE in PPE as a preventive health strategy.

    Extracardiac rhabdomyomas are rare benign entities that usually occur in the head and neck region. Although genital rhabdomyoma is known to occur in the lower genital tract of young and middle-aged women, involvement of the anatomically adjacent urethra by rhabdomyoma is exceedingly rare. We present a case of genital rhabdomyoma arising from the urethra of an infant girl. The tumor was characterized by the submucosal presence of mature-appearing rhabdomyoblastic cells containing conspicuous cross-striations, with the cells set in a collagenous stroma. Necrosis and mitoses were absent. Skeletal muscle differentiation of the tumor cells was supported by positive immunohistochemical staining for desmin and myogenin. To our knowledge, this is the first case of urethral genital-type rhabdomyoma in a child.

    Our purpose was to test the effect of botulinum toxin injections on hypertonic pelvic floor muscles of patients suffering from genital pain syndromes. We report two cases of women complaining of a genital pain syndrome resistant to pharmacological therapies and rehabilitation exercises associated with a documented involuntary tonic contraction of the levator ani muscle as a defense reaction triggered by vulvar pain. We performed botulinum toxin injections into the levator ani with the intent to relieve pelvic muscular spasms. Within a few days after the injections both the patients reported a complete resolution of the painful symptomatology, lasting for several months. Our experience suggests that botulinum injections are indicated in patients with genital pain syndrome with documented pelvic muscle hyperactivity, whose symptoms arise not only from genital inflammation and lesions, but also, and sometimes chiefly, from levator ani myalgia.

    1979-07-27

    Tumours arising in the bronchial mucous glands closely resemble tumours arising in the mixed salivary glands. Bronchial mucous gland tumours account for less than 0.5 per cent of all lung tumours. Twenty six tumours are reviewed and they have been divided into five types, (a) adenoidcystic carcinomas, (b) muco-epidermoid tumors, (c) mixed (pleomorphic) tumors, (d) cystadenomas and (f) oxyphilic adenoma. The clinical features, and postoperative course of the patients are reviewed. Adenocystic carcinomas, arising in the bronchus frequently involve the neighbouring trachea and spread mainly by direct infiltration. Most muco-epidermoid bronchial tumours were confined to young persons, and the only malignant muco-epidermoid tumour occurred in an elderly person. The prognosis in young persons is good provided the tumours are completely excised. The two mixed bronchial tumours resembled their salivary counterparts and one subsequently behaved as a carcinoma and metastasised. Bronchial cystadenomas all proved to be benign tumours but in two cases were associated with surface papillary proliferation. The only example of an oxyphil cell adenoma was discovered at post mortem examination. The histogenesis of the tumours is considered.

    One of the most important trends in intraoperative neural monitoring (IONM) in thyroid surgery is currently the real-time monitoring of the vagus nerve (VN) in order to prevent recurrent laryngeal nerve (RLN) iatrogenic damages. Notably, continuous intraoperative neuromonitoring (C-IONM) seems to be superior to intermitted intraoperative neural monitoring (I-IONM) because it enhances standardization by permanent vagus nerve (VN) stimulation, and it provides entire and constant RLN function monitoring as the surgeon dissects and removes the thyroid gland. It also has to be highlighted that the surgical maneuvers for the automatic periodic stimulating (APS) placement must be accurate and standardized in order to avoid a potential iatrogenic morbidity on the VN function. We recommend the experienced surgeon be very careful in each step, with cautious dissection. With this review article we provide a comprehensive analyses of C-IONM technique with the APS accessory for conventional and endoscopic thyroid surgery. PMID:26054997

    The colleterial glands of insects are organs associated with the female genital apparatus. In cockroaches, these glands produce secretions that cover two parallel rows of eggs during oviposition, and in oviparous species, these secretions become the tanned, sculpted, rigid outer casing of the ootheca. The goal of this study was to compare the gross anatomy of the colleterial glands and the ultrastructure of their component tubules in the phylogenetically significant genera Cryptocercus (Blattaria) and Mastotermes (Isoptera). Recent studies indicate that cockroaches in the genus Cryptocercus are the sister group of termites, and Mastotermes is the only termite known to produce a cockroach-like ootheca. One additional oviparous cockroach, Therea, and two additional termites, Zootermopsis and Pseudacanthotermes, were also examined. As in other cockroaches, the colleterial glands of Cryptocercus and Therea are asymmetrical, with a well developed bipartite left gland and a smaller right gland. In the termites Mastotermes, Zootermopsis, and Pseudacanthotermes, the colleterial glands are composed of a well-developed, paired, anterior gland and a small posterior gland; histological staining and cytological evidence suggest that these are homologues of the left and the right colleterial glands of cockroaches, respectively. At the ultrastructural level, colleterial gland tubules are made of cells belonging to a modified class 1 type cell in the cockroaches, in Mastotermes, and in Zootermopsis; the latter lays its eggs singly, without a surrounding ootheca-like structure. In the advanced termite Pseudacanthotermes, the tubules are made of secretory units belonging to the class 3 cell type. This study demonstrates that the cytological characteristics of colleterial glands in basal termites are similar to those of cockroaches, whether the termite secretes an oothecal casing that covers two parallel rows of eggs, as in Mastotermes, or lays its eggs singly, as in Zootermopsis

    A 33-year-old male patient with a slow-growing, painless, well-circumscribed soft tissue mass on the left parotid region is presented. The clinical impression was that of a benign salivary gland tumor. The tumor was situated in the superficial lobe of the gland, and a superficial parotidectomy was performed, with preservation of the facial nerve. Histopathologic examination results revealed a sialolipoma of the parotid gland and a lesion that consisted of both mature adipose tissue and glandular elements. Sialolipomas share similar clinical features with conventional lipomas of the salivary glands. Preoperative diagnosis is generally difficult, and computed tomographic scanning is useful in defining these benign parotid gland masses. Superficial parotidectomy is the usual surgical treatment for parotid gland superficial lobe lipomas, with near-total absence of recurrence.

    Tumors of salivary glands arise mainly from the parotid gland. Magnetic Resonance Imaging (MRI) is mandatory not only to localize precisely the tumor within the gland but also to differentiate between benign and malignant neoplasms, in competition with cytology in fine-needle aspiration biopsy. Tumors without risk of transformation, such as adenolymphoma, are not systematically operated on. Indications of roentgenotherapy and irradiation volumes depend on histologic type, localisation and size of the tumor.

    Salivary gland tumors are a rare, histologically heterogeneous group of tumors which constitute approximately 4–6 % of all head and neck neoplasms. In 2/3 of cases they are benign, especially in the parotid gland. We report about a rare tumor of the parotid gland presenting as an extraskeletal chondroma. Histologically there were multiple S 100 protein-positive nests of chondrocytes. The externally completed cytology suspected a pleomorphic adenoma, nevertheless, the final histopathological findings showed another tumor entity.

    Genital tubercles of 70 newborn male and female rats were transplated into the brains of unrelated infant rats. Seven other tubercles were placed subcutaneously. All female, and some male, hosts were injected with testosterone propionate. After surviving from 2-24 days,, histological study of 49 successful grafts showed survival of the urethral and balano-preputial epithelia and growth of the preputial glands, which formed secretion-filled cysts and became the major component of the graft. The fate of the mesodermal tissues witin the glands varied between remaining in an undeveloped state, with only pale fibrouw tissue and an area of granular degeneration and giant cells, and achieving an incompletely differentiatel state in which erectile tissue and the anterior process of fibrocartilage had formed and the glans had grown but the penile bone and its secondary growth cartilage failed to appear. Grafts could reach this degree of differentiation of the glands irrespective of transplantation site, attachment to the host dura, the sex of donor or host, and whether or not male hosts were given exogenous hormone.

    Meibomian gland dysfunction is a common ocular disorder affecting from 39 to 50% of population. Despite that, so far a pathophysiology path of the disease remains unknown, moreover there is no distinct border between physiology and the disease. There has been no clear diagnostic criteria. The purpose of this review was to combine a current knowledge of Meibomian gland anatomy, Meibomian gland dysfunction epidemiology, as well as presenting current definition, nomenclature, classification and diagnostic criteria. The importance of diagnosis associated with conditions such as aqueous tear deficiency, seborrheic dermatitis, and rosacea is emphasized. The available treatment methods are discussed.

    Classification of neoplasms of any organ should be predicted on the patterns of differentiation that reflect the organization and cell types of the parental tissue. The ability to classify a neoplasm instills confidence in its predicted biologic behavior and the selection of treatment. There has not been a single universally used classification system for salivary gland tumor. Histogenetic and morphogenetic concepts and the developing information on various molecular parameters will have significant influence on the classification of salivary glands tumors. In this article we would highlight the histogenetic and morphogenetic concepts in salivary gland neoplasms and elaborate on the taxonomic system of classification of salivary gland neoplasms.

    PubMed

    Alvarez-Salas, L M; López-Bayghen, E

    1995-01-01

    Human papillomavirus (HPV) specifically infect stratified epithelial cells, causing benign and malignant neoplasia. Several elements directing this virus' genetic expression are present in a non-coding region called LCR. HPV infection starts in the basal cells of stratified epithelia, where a particular combination of cellular factors interacting with the LCR starts the transcription of the viral E6 and E7 oncogenes. The E6 and E7 genes alter the cell cycle because they interact and inactivate tumor suppressor proteins: E6 binds and degrades protein p53 and E7 associates with p105RB. E1 and E2 are the next synthesized proteins. E2 blocks the early transcription and permits E1 specific binding to the viral origin of replication located within the LCR, initiating the viral genome replication. Following the course of viral infection, the E2-induced E6 and E7 down-regulation releases p53 and p105RB proteins, and the differentiation process can continue. Then, a putative late promoter can activate the capsid genes L1 and L2. At this step, mature virions can be detected in the upper layers of the epithelium. Disruption in E2 gene transcription is usually associated to genital malignant neoplasia. In the absence of E2, E6 and E7 remain constitutively expressed, sustaining the immortality of the infected cell and blocking the epithelial differentiation program.

  9. Female genital alteration: a compromise solution.

    Despite 30 years of advocacy, the prevalence of non-therapeutic female genital alteration (FGA) in minors is stable in many countries. Educational efforts have minimally changed the prevalence of this procedure in regions where it has been widely practiced. In order to better protect female children from the serious and long-term harms of some types of non-therapeutic FGA, we must adopt a more nuanced position that acknowledges a wide spectrum of procedures that alter female genitalia. We offer a revised categorisation for non-therapeutic FGA that groups procedures by effect and not by process. Acceptance of de minimis procedures that generally do not carry long-term medical risks is culturally sensitive, does not discriminate on the basis of gender, and does not violate human rights. More morbid procedures should not be performed. However, accepting de minimis non-therapeutic f FGA procedures enhances the effort of compassionate practitioners searching for a compromise position that respects cultural differences but protects the health of their patients.

    Female genital cutting (FGC), a prevalent practice in most African countries not just seriously endangers a girl's lifetime health, but it is also considered a human rights violation. In June 1999, the Intra-Agency Working Group on FGC held a symposium with US Agency for International Development (USAID) staff to explore ways of incorporating into USAID program activities to eradicate the practice of FGC. One of the presentations at the symposium concerned "circumcision with words". This ceremony is an alternative rite of passage; it is conducted through a 5-day seclusion, culminating in a 1-day celebration including feasting and gift giving. The alternative rites include 1) self-esteem and coping with criticism; 2) responsibility for one¿s own decision; 3) dating and courtship; 4) coping with peer pressure; 5) personal hygiene; 6) marriage; 7) pregnancy and sexually transmitted disease and AIDS prevention; 8) contraception; 9) FGC, early marriage, and gender empowerment, including the rights of the girl child; 10) respect for community; and 11) respect for elders. Alternative rites of passage are gaining community acceptance and by Kenya Medical Association. None of the girls who participated in the ceremony were circumcised later. PMID:12295634

    Accessory (supernumerary) intrathoracic ribs are a very rare congenital disorder. Here, we present the first case of multiple supernumerary intrathoracic ribs in an adult, which are present consecutively between ribs 1 and 4 and without articulation with the vertebrae. Despite this, anatomical variation is usually silent and accidentally discovered; its knowledge can prevent confusion with other structures during imaging diagnostic techniques of thoracic pathologies.
