Medical and Sexual History the purpose of obtaining the medical and sexual history is essentially twofold: first crestor cholesterol medication side effects cheap simvastatin 10 mg with visa, to identify any behavior or medical conditions that may cause the doctor to misinterpret the clinical findings, for example, menstrual bleed ing; and second, to identify any medical problems that may be attributable to the sexual assault, for example, bleeding, pain, or discharge. Other specific details may be required if emergency contraception is being considered. When children are examined, the parent or caregiver should provide comprehensive details of the past medical history. When adults are exam ined, only relevant medical and sexual history should be sought because confidentiality cannot be guaranteed. What constitutes relevant medical his tory must be determined on a case-by-case basis by considering the differ ential causes for any medical findings and the persistence data for the different sexual acts. Forensic practitioners should not ask suspects about the alleged incident or their sexual history. General Examination In all cases, a complete general medical examination should be conducted to document injuries and to note any disease that may affect the interpretation of the medical findings. Anogenital Examination Whenever there is a clear account of the alleged incident, the anogenital examination should be tailored to the individual case. However, in some cases, the complainant may not be aware of the nature of the sexual assault. Further more, children and some adults may not have the language skills or may feel unable to provide a detailed account of the sexual acts at the initial interview. In such cases, a comprehensive anogenital examination should be undertaken if the patient or the person with legal authority to consent on behalf of the patient gives his or her consent. With the specific consent of the patient, the video/ photograph can be shown to other colleagues for second opinions, viewed by a named doctor providing expert testimony for the defense, and used for teach ing purposes. The material should not be released to nonmedical parties except on the directions of the court. Prevention of Contamination To ensure that there is no accidental transfer of body fluids or fibers between the parties who have been involved in a sexual act, each complainant and each suspect should be transported in separate vehicles and examined in different locations by different forensic practitioners. There fore, gloves must be worn throughout the forensic examination and changed when sampling different body areas. In addition, the forensic physician should avoid talking, coughing, or sneezing over unsealed samples and should handle all samples as little as possible. If a doctor believes that there is a possibility that he or she will cough or sneeze over an unsheathed swab, a face mask should be worn when the sample is being obtained. Collection of Forensic Samples the swabs and containers used to collect forensic evidence differ from those used in clinical tests. The quality and integrity of any swab or con tainer used to obtain a forensic sample must be ensured. The provision of sealed, standardized clinical forensic examination kits or modules ensures that these requirements can be guaranteed (8,9). Blood and urine samples for drug and alcohol analysis should be placed in containers with a preservative that prevents decomposition and fermentation. Because many of the samples are subsequently frozen, all the containers should be shatterproof. However, if storage space is restricted, then any used proctoscopes or specula may be swabbed and only the swabs retained for later forensic sampling. Sterile water may be used to moisten the proctoscope/speculum to facili tate its insertion into a body orifice. Other lubricants should not be used when body fluid analysis or lubricant identification may be pertinent to the case (see Heading 11 on Lubricants). Controls An unopened swab from each batch should be retained and sent with the samples as a control for that batch of swabs. If any water is used in the sampling process, the remaining water in the ampule or an unused swab moistened with some of the water should be retained as a control sample for the water. Packaging and Continuity Any retrieved items must be packaged quickly and efficiently to prevent accidental loss of material and minimize decomposition of the sample. The use of bags with integral tamper-evident seals is recommended to prove that the sample has not been contaminated with exogenous substances since it was sealed. The exhibit should be labeled with the site of the sample, the date and time (24-h clock) it was obtained, and the name of the examinee. Again, the use of bags with integral labels will prevent accidental detachment of this vital information (see Fig. The latter is particularly important when more than one sample has been obtained from the same site (7). Every exhibit should be signed by the person who first handled Sexual Assualt Examination 67 Fig. It is good practice for others who subsequently handle the exhibit to sign the label also, so that, if necessary, they can be called to court to explain their part in collection, transport, and storage (10). Clothing should be placed in bags made of material, such as paper, that prevents the accumu lation of condensation, which could accelerate decomposition of body flu ids. When the clothing is overtly wet or possibly contaminated with accelerants, the forensic science laboratory should be asked for advice on packaging and storage. The following additional information should then be recorded on the appropriate label: The forensic scientist must be provided with salient information regard ing the incident and subsequent actions of the complainant in order to deter mine the type of forensic analysis required. Their abundance and hypervariability make them ideal markers for the identification of an indi vidual. As yet, it is unclear how useful this tool will be in the forensic setting (see Subheadings 5. Therefore, in sexual offenses, the selection of material to be analyzed by this technique is limited and its use needs careful consideration. The forensic science laboratory must be notified when it is alleged that people who are closely related have been involved in a sexual offense, because their profiles will have greater similarity than profiles from individuals picked at random, and further differentiating tests may need to be performed. Method of Sampling All areas of unwashed skin that have been licked, kissed, sucked, bitten, or ejaculated on by either the assailant or the complainant must be sampled. There fore, when dealing with an assault conducted by an unknown assailant, con sideration should be given to sampling marks or injuries on the skin that the complainant attributes to direct contact by the offender. However, the prob lem with this type of sampling is there is considerable lack of understanding about issues of transfer and persistence (24). Consequently, speculative skin swabbing in the absence of visible marks or injuries is not recommended. Although several techniques, including the use of surgical gauze pads (25) and cigarette papers (26), have been employed to recover saliva and other trace evidence from the skin with variable success, the use of sterile swabs is the most widely used technique that has received international endorsement (27). If the skin appears moist, the stain should be retrieved on dry swabs, which are then placed in sheaths without transport medium. When using this tech nique, sterile water is used to wet completely the cotton tip of the first swab. The tip of the swab is then rolled over the area of skin using circular motions while rotating the swab on its long axis to ensure maximum contact between 72 Rogers and Newton the skin and the swab. Then, a second dry swab is rolled over the same area to absorb the water left on the skin by the initial swab and collect any remaining cells. The forensic practitioner should use as many swabs as necessary to remove any visible stain (repeating wet swab followed by dry swab). In addition, other authors have com mented that detergents, lubricants (particularly those that contain petroleum jelly), and milk also fluoresce (32). However, when semen stains are exposed to a high-intensity light source of variable wavelengths. A recent experiment by Marshall and colleagues found that semen from a single donor could be detected on skin using several excitation wavelengths (emitted by a Poliray?) and emission filter combinations (34). Optimal results were obtained using 415 nm 40 nm band-pass filter and a 475 high-pass and 505 band-pass 40 nm interference filter. More research must be conducted using semen from multiple donors and isolating semen from other fluorescing contaminants, such as oils. Forensic Analysis the most common reason for forensic analysis of skin swabs is after licking, kissing, or biting of the skin. Forensic analysis for other body fluids or exogenous substances is considered elsewhere in the chapter. Detection of Saliva the only means of confirming the presence of saliva on the skin is by detecting the enzyme amylase. However, in practice, this enzyme is not usu ally found in high enough concentrations in samples removed from the skin (Austin, C.

Laser light cholesterol medication for liver disease purchase genuine simvastatin online, termed monochromatic light since it is 456 Hematology emitted as a single wavelength, differs from bright field light in its intensity, its coherence (i. These characteristics allow for the detection interference in the laser beam and enable enumeration and differentiation of cell types. As the cells pass through the sensing zone and interrupt the beam, light is scattered in all directions. Light scatter results form the interaction between the processes of absorption, (diffraction bending around corners or surface of cell), refraction (bending because of a change in speed), and reflection (backward rays caused by obstruction). Lenses fitted with blocker bars to prevent nonscattered light from entering the detector are used to collect the scattered light. A series of filters and mirrors separate the varying wavelengths and present them to the photo detectors. Photodiodes convert light photons to electronic signals proportional in magnitude to the amount of light collected. Analog-to digital converters change the electronic pulses to digital signals for computer analysis. Forward-angle light scatter (0 degrees) correlates with cell volume or size, primarily because of diffraction of light. Orthogonal light scatter (90 degrees), or side scatter, results form refraction and reflection of light from larger structures inside the cell and correlates with degree of internal complexity. Forward low-angle scatter (2-3 degrees) and forward high-angle scatter (5-15 degrees) also correlate with cell volume and refractive index or with internal complexity, respectively. Differential scatter is the combination of this low and high-angle forward light scatter, primarily utilized on Bayer systems for cellular analysis. The angles of light scatter measure by the different flow cytometers are manufacturer and method specific. In most cases it is due to a mutation in factor V in which Arg 506 is replaced with Gln (factor V Leiden). Acute leukemia A malignant hematopoietic stem cell disorder characterized by proliferation and accumulation of immature and nonfunctional hematopoietic cells in the bone marrow and other organs. Peripheral blood smear reveals the presence of many undifferentiated or minimally differentiated cells. Acute phase reactant Plasma protein that rises rapidly in response to inflammation, infection, or tissue injury.

Basophilic stippling Erythrocyte inclusions composed of precipitated ribonucleoprotein and mitochondrial remnant. Observed on Romanowsky stained blood smears as diffuse or punctate bluish black granules in toxic states such as drug (lead) exposure. Formed from highly organized, differentiated cells that do not spread or invade surrounding tissue. Bilineage leukemia A leukemia that has two separate populations of leukemic cells, one of which phenotypes as lymphoid and the other as myeloid. Biphenotypic leukemia An acute leukemia that has myeloid and lymphoid markers on the same population of neoplastic cells. Birefringent Characteristic of a substance to change the direction of light rays that are directed at the substance; can be used to identify crystals. As the H+ concentration in tissues increases, the affinity of hemoglobin for oxygen is decreased, permitting unloading of oxygen. Bone marrow trephine Removal of a small piece of the bone marrow biopsy core that contains marrow, fat, and trabeula. Examination of the trephine biopsy is useful in observing the bone marrow architecture and cellularity and allows interpretation of the spatial relationships of bone, fat, and marrow cellularity.

Treatment and Control excision for anesthetic use 5-10 ml of 2% lidocaine across the dorsum of the penis near the preputial orifice while the penis is held in extension cholesterol test glasgow generic simvastatin 20mg without prescription, a ring block proximal to the lesion, or local anesthetic at the base of the fibropapilloma. It may be beneficial to suture the epithelium, especially if the wart was broad based. Alternatively, hemorrhage can be controlled with electrocautery or cryotherapy, but slow healing wounds may result. The bull should be re-examined every 1-2 weeks in order to pull off the necrotic warts and tighten ligatures on those that are not necrotic. The efficacy of autogenous vaccines may be superior to that of commercial vaccines. This is a characteristic reaction of this area to 7 various infectious organisms and irritants but it generally should not result in infertility. The local application of oily antibiotic preparations has also been used for therapy. The local application of oily antibiotic preparations may reduce the possibility of preputial adhesions or scarring. The local application of antibiotic or antiseptic preparations to the preputial cavityis usually performed with a 60 ml syringe inserted into the preputial orifice while the orifice is closed off around the syringe with one hand. After infusion of the antibiotic, the syringe is removed but the orifice is held closed while the antibiotic is massaged in. The syringe can also be attached to an infusion pipette for this procedure, but care most be taken not to traumatize the prepuce with the pipette. The former is usually infused in 50-60 m l quantities and the latter is infused in similar quantities, but repeated until the hydrogen peroxide no longer foams. Alternatively, 1-3 tubes of mastitis ointment can be infused, using the tube as an infus ion device. Less commonly, hair rings may lacerate the penis, cause a urethral fistula, or cause sloughing of the glans penis. If he is valuable, collect semen by electroejaculation at an artificial ins em ination centre. These muscles, along with the elastic membrane and retractor penis muscles, serve to retract the cranial portion of the prepuce. This usually causes little problem by itself, but may predispose to trauma of the prepuce. These bulls also tend to have large preputial orifices and an excessive amount of preputial mucosa. Treatment Laceration with phimosis the penis and prepuce cannot be extended out of the sheath because of stenosis at the laceration site. The prepuce may be stenotic after surgery but the contracted elastic tissue will relax over time. It may take up to 6 months for complete healing to allow the penis to extend freely. For the surgical procedures, refer to Current Therapy in Theriogenology 2, Current Therapy in Large Animal Theriogenology, Large Animal Urogenital Surgery, Bovine and Equine Urogenital Surgery, other surgery textbooks, and the surgery notes. Injuries or laceration with prolapse most common in the polled and Bos indicus breeds clip the preputial hairs. Some veterinarians will then soak the prolapsed portion for 30-90 minutes in warm magnesium sulphate solution in a plastic jug that has been cut in half and strapped around the abdomen of the bull. Some clinicians prefer to remove edema from the prepuce by spraying it with water. If desired, the tape can be covered with a finger from a rubber glove (tip removed) to keep it dry. If the prepuce is not wrapped, it should be washed and massaged with ointment daily. The drain is sutured to the skin of the free portion of the penis with 4 to 6 interrupted sutures of 0 to 00 absorbable suture material (making s ure to avoid the urethra and corpus spongiosum penis). A (perhaps less desirable) alternative is to use elastic tape to tape in the rubber or plastic urine drainage tube (described above) and change this ?bandage? at least once or twice weekly. Surgery might be necessary to remove the stenotic or fibrotic portion of the prolapse. If the longitudinal laceration has healed transversely, the prepuce will be shortened and have a pendulous portion. Removal of the excessive preputial mucosa on Bos indicus bulls or removing some skin to make their prepuce less pendulous may prevent recurrence, although breeders should be encouraged to select against bulls with very pendulous prepuces. Especially in Bos taurus bulls, one must be careful not to remove too much preputial mucosa or the penis will not extend far enough. One reference states that the remaining portion of the preputial membrane should be at least slightly longer than twice the length of the free portion of the penis. However, if there is severe edema, a deep laceration, or deep necrosis and fibrosis, the prognosis is guarded to poor. If the abscess cannot be drained from inside the preputial cavity, conservative therapy (systemic antibiotics, hydrotherapy, and rest from sexual activity) may be the best option for resolution of the scar tissue. Refer to Large Animal Urogenital Surgery, Bovine and Equine Urogenital Surgery, and other textbooks for further details on this condition. As he gets older, the abdomen becomes deeper and the bull less agile, and he is unable to breed. If this is not possible, it has been suggested that a general anesthetic or an internal pudendal nerve block (ref. If the length of the extended penis is < 25 cm from the tip to the preputial orifice, the penis of the bull is too short. Treatment analgesics, diuretics (if urine output is not compromised), and non steroidal anti-inflammatories. Sedatives should only be administered if they are essential to ensure operator safety. Some authors suggest repeatedly applying pressure bandages and massaging the penis through the bandages to reduce the edema before applying a longer-term bandage. The penis should be coated with an emollient to prevent drying and cracking of the epithelium. Alternatively, the penis can be retained in the sheath by a nylon net or panty hose that has been suspended at the preputial orifice by rubber tubing. If paralysis of the penis persists, amputation or surgical retraction may be necessary. Whenever possible, the stallion should be castrated and the castration incisions allowed to heal prior to amputation or surgical retraction of the penis. Circumcision (the reefing operation) may be required if there is excessive preputial scarring. These procedures are described in Current Therapy in Theriogenology 2, Equine Reproduction, Large Animal Urogenital Surgery, Bovine and Equine Urogenital Surgery, other surgery textbooks, etc. Persistent and extensive medical therapy s hould precede a decision to perform any of these surgeries. Reserpine has been reported to cause penile paralysis in a stallion when used for a prolonged period in order to modify his behavior. Etorphine has also been reported to be a cause of penile paralysis or 18 priapism in the horse. Pathogenesis and clinical signs of penile paralysis not well understood tranquilizers cause blood stasis in the corpus cavernosum penis (ccp) and may result in loss of vascular tone. Tranquilizers relax the smooth muscles of the ccp as well as the retractor penis muscles. Treatment benztropine mesylate (= Cogentin has anticholinergic and antihistaminic effects) @ 8 mg (0. However, the horse may not regain the ability to retract the penis and it often prolapses again after the retention device is removed. Alternative methods of collecting stallions are also discussed in A Manual for Theriogenologyunder ?Semen Collection. Collection by electroejaculation under general anesthesia can also be attempted on a limited basis (may be a danger of tearing the rectum with the probe). Ex copula ejaculation 19 could also be attempted us ing imipramine and xylazine (Proc.

Refractive index: the extent of phase retardation of light as it passes through a m edium. To avoid breaking the objective lens and the slide, look at the objective and stage from the front or side, not through the eye pieces. Use the coarse focus to adjust the height of the stage so that the slide is alm ost in contact with the objective. Note which way the coarse focus has to be turned to lower the stage away from the objective. Rotate the knurled ring at the base of the eyepiece to ?+? or until the focus is appropriate for your eye. This position will generally be achieved when the condenser is in the top-m ost position.

Ovarian horm ones regulate the secretion of cervical m ucus: 17E-estradiol stim ulates the production of copious am ounts of watery m ucus and progesterone inhibits the secretory activity of the epithelial cells. In wom en of reproductive age with a norm al m enstrual cycle, the daily m ucus production varies from 500Pl at m id-cycle to less than 100 Pl at other tim es. In addition, leukocytes and cellular debris from the uterine and cervical epithelia are present. It exhib its a num ber of rheological properties: y Viscosity (consistency) is influenced by the m olecular arrangem ent and by the protein and ionic concentrations of the cervical m ucus. M ucus varies during the cycle from highly viscous (often cellular) just before m enstruation to watery at m id-cycle just before ovulation. By the tim e ovulation is com pleted, the vis cosity of the m ucus has already begun to increase again. Cervical m ucus is a hydrogel com prising a high-viscosity com ponent and a low viscosity com ponent m ade up of electrolytes, organic com pounds and soluble proteins. Sperm atozoa can penetrate hum an cervical m ucus from approxim ately the ninth day of a norm al 28-day cycle; penetrability increases gradually to reach a peak just before ovulation. Sperm penetration then begins to dim inish before large changes in m ucus properties are apparent. M otile sperm atozoa m ay be guided by strands of cervical m ucus to the cervical crypts, where they m ay be retained and released slowly into the uterus and Fallopian tubes. Collect cervical m ucus from the endocervical canal by aspiration with a m ucus syringe, tuberculin syringe (without needle), pipette or polyethylene tube. The m anner in which suction pressure is applied to the collection device should be standardized. Advance the tip of the device approxim ately 1cm into the cervical canal before applying suction. Just before the device is com pletely withdrawn from the external cervical os, release the suction pressure. It is then advisable to clam p the catheter to protect against accum ulation of air bubbles or vaginal m aterial in the collected m ucus when the device is rem oved from the cervical canal. W henever possible, the quality of the m ucus should be evaluated im m ediately on collection. This procedure will produce a m ore hydrated, and therefore less viscous, m ucus secretion (Eggert-Kruse et al. W hile this approach m ay be useful in assessing sperm ?m ucus interaction in vitro, it will not necessarily re? If possible, m ucus specim ens should be used within 2 days of collection; the interval between collection and use should always be noted. Rheological and sperm penetration tests should not be perform ed on m ucus specim ens that have been frozen and thawed. Appendix 6 contains a sam ple form for scoring and recording these cervical m ucus properties according to the system devised by M oghissi (1976), based on an original proposal by Insler et al. The score is derived from the volum e of cervical m ucus collected (see Sec tion A5. The pH of the m ucus is not included in the total cervical m ucus score, but should be m easured as an im portant determ inant of sperm ?m ucus interaction (Eggert-Kruse et al. A score greater than 10 is usually indicative of good cervical m ucus favouring sperm penetration; a score of less than 10 m ay m ean that the cervical m ucus is unfavour able to sperm penetration. It can be estim ated from the length of the m ucus within catheter tubing of known diam eter (see Box A5. There is little resistance to sperm m igration through the cervical m ucus in m id-cycle, but viscous m ucus? such as that observed during the luteal phase? form s a m ore form idable barrier. Viscosity is scored as follows: 0 = thick, highly viscous, prem enstrual m ucus 1 = m ucus of interm ediate viscosity 2 = m ildly viscous m ucus 3 = watery, m inim ally viscous, m id-cycle (preovulatory) m ucus A5. Such preparations reveal various patterns of crystallization, which m ay have a fern-like appearance. Depending on the com position of the m ucus, the ?ferns? m ay have only a prim ary stem, or the stem m ay branch once, twice or three tim es to produce secondary, tertiary and quaternary stem s.

Shank and keel length, chest and head width, testes weight, abdominal fat pad weight, and pectoralis major and minor muscle weight were determined for 40 birds at 6, 12, 18, 20, 22, 23, 24, 25, 26, and 62 wk of age. Semen concentration, semen volume, sperm motility, fertility, fertile period, and plasma testosterone were determined at 28, 32, 36, 40, 44, 50, 54, 58, and 62 wk of age for 45 birds. Male broiler breeders appear resilient to a short period of weight loss, prior to production, without a negative impact on reproduction. The birds are fed ad libitum, as broilers, for the first 6 wk of production in order to assess their growth potential. Males are selected based upon broiler characteristics, growth rate and breast muscle deposition to produce the next generation. Overfeeding of male broiler breeders, ?broilerizing?, often results in birds that are heavier at 42 days of age than what is recommended at sexual maturity. Hocking and Duff (1989) postulated that the increased muscularity of heavy males reduced mating efficiency. The external characteristics (chest width, keel length, shank length, comb height, shank score, and shank color) of male broiler breeders have been proposed as methods of evaluating reproductive potential. In male broiler breeders, the chest width becomes very large as the breast thickens towards the end of the reproductive period. Male broiler breeders may find it anatomically difficult to achieve cloacal contact with increased chest width (Hocking and Bernard, 1997). Shank length (Jaap, 1938) and more recently keel length have been associated with skeletal frame size. Head width is of interest because of sex separate feeding methods (McDaniel, 1986; Robinson et al. Fitting simple barriers to the female feeding trough to exclude the males which have larger heads has made it possible to feed male and female broiler breeders different diets and quantities (McDaniel, 1986; 80 Hocking, 1990b). Comb development has been considered an external sex characteristic that mirrors reproductive development of both males and females (Lowry, 1958; Hocking, 1990ab). Red color along the length of the shank has been observed in some broiler breeder flocks. It has been proposed that a red shank, as opposed to a purely yellow colored shank, may relate to a reproductively active male (J. During rearing, body weight management of broiler breeder males may impact the reproductive efficiency of males throughout production. Parker and McSpadden (1943) reported that severe restriction between 42 to 72% of free choice, after photostimulation, had a detrimental effect on male fertility. The photoperiod consisted of 23 h of light and 1 h of darkness (23L: 1D) for the first 3 d. From 3 d to 22 wk of age, the birds received 8 h of light (8L: 16D) provided at 10 lux intensity. From 3 wk to 20 wk of age, birds were fed on alternate days with twice the daily feed allotment fed each feed day (skip-a-day feeding) to promote higher flock uniformity. Forty birds (10 birds /treatment) were randomly assigned to a sample time (6, 12, 18, 20, and weekly from 22 to 26 wk of 82 age). The sample group was used to determine conformation, skeletal measurements, and carcass characteristics. The P30 treatment was removed at 30 wk due to difficulties with record management. Forty-five birds were individually caged at 20 wk and individually fed for assessment of the reproductive characteristics. The Animal Policy and Welfare Committee of the Faculty of Agriculture, Forestry and Home Economics of the University of Alberta approved the experimental protocol. From 32 to 62 wk of age, external measurements were recorded on the 45 males used for the assessment of reproductive characteristics. Shank (tarsometatatsus) length was measured as the distance from the middle of the foot pad to the hock joint on the left leg (Robinson et al. Keel length was measured from the point of fusion in the clavicle to the ventral portion of the sternum. The chest width was assessed approximately 20 mm below the shoulder joint measuring from the transverse distance across the pectoralis major muscle. Head width was assessed across the two posterior bony projections of the mandible. Comb height 2 measurements were taken by image analysis (Northern Exposure, 2000 ) at 12, 18, 20 and weekly from 22 to 26 wk of age on the 40 males processed for carcass characteristics. Comb height was measured, on the second blade of the comb, along the length of the blade from the top of the comb to the body of the comb. Shank color was assessed at 12, 18, 20 and weekly from 22 to 26 wk of age using Paintshop Pro (Jasc Software Ver.
