Testis torsion in undescended testis
•Download as PPTX, PDF•
1 like•888 views
Testis torsion can occur in undescended testes due to the abnormal positioning of the testis which increases risk. It is not uncommon, accounting for 23% of cases of torsion. However, delayed diagnosis leads to a low salvage rate of only 10% for cryptorchid testes with torsion compared to 56% for isolated torsion. Abdominal or groin pain in children with an undescended testis warrants investigation including ultrasound or exploratory surgery to rule out torsion due to the increased risk and low chance of testis survival if not addressed promptly. Proper diagnosis is important to distinguish torsion from other causes of pain like incarcerated hernia.

Undescended Testis (UDT)
Undescended testis, or cryptorchidism, refers to the absence of one or both testes from the normal scrotal position. It occurs in 1-4% of full-term and 1-45% of preterm newborn boys. The specific cause is often unknown, but risk factors include prematurity and maternal estrogen exposure. Diagnosis involves examination to locate any undescended testes. Early surgical treatment before age 18 months is recommended to preserve fertility and reduce cancer risks. Options include inguinal or abdominal orchidopexy. Long term risks include reduced sperm counts and increased testicular cancer risk.

evaluation of Undescended testes
This document discusses undescended testes (UDT), beginning with the normal embryological descent of the testes from the abdomen into the scrotum. UDT occurs when this descent is halted and can result in increased risks of malignancy, infertility, torsion and hernia. Clinical presentation of UDT varies depending on whether the testes are palpable or impalpable. Management involves hormonal therapy, imaging, and surgical orchidopexy before age 2 to minimize risks. Complications of UDT include increased risks of testicular cancer, torsion, hernia, and infertility.
Recent trends in management of undescended testes
This document discusses recent trends in the management of undescended testes. It begins with definitions and prevalence rates of undescended testes.

Undescended Testis- Cryptorchidism
1. Undescended testis, or cryptorchidism, occurs when one or both testes fail to descend into the scrotum. This is a common genital abnormality in boys.
2. Cryptorchidism increases the risks of infertility and testicular cancer later in life. The failure of testes to descend properly can lead to degeneration of germ cells and impaired sperm production.
3. Treatment involves hormone therapy or surgery to bring the undescended testes into the scrotum. This is done to preserve fertility and reduce cancer risks. Timely treatment is important for normal testicular development.
Cryptorchidism
Cryptorchidism is the failure of one or both testes to descend into the scrotum. It occurs in approximately 3% of full term and 30% of premature baby boys. There are several types including retractile, palpable, nonpalpable, and ectopic. Risk factors include low birth weight, prematurity, family history, and maternal health conditions. Diagnosis involves physical examination and may include ultrasound, CT scan, or laparoscopy. Treatment is usually hormone therapy or surgery to bring the testes into the scrotum, helping them develop properly and reducing cancer risks.

Undescended Testis
Undescended testis, or cryptorchidism, is a common condition in infants where one or both testes fail to descend into the scrotum. It occurs in approximately 3% of term male infants and is more common in premature infants. Left untreated, undescended testis can lead to infertility and an increased risk of testicular cancer. The standard treatment is orchidopexy surgery to bring the testis into the scrotum, which is usually performed between 6-12 months of age. For intra-abdominal undescended testes, a two-stage surgical approach may be used.

Key causes, classifications, diagnostic tests, and management strategies for azoospermia are presented.
Undescended testis
Gaurav Nahar discusses undescended testis (cryptorchidism). Cryptorchidism occurs when one or both testes fail to descend into the scrotum. It has a prevalence of 1-4% in full term males and 1-45% in preterm males. Testicular descent is a complex process involving hormonal and mechanical factors. Cryptorchidism can be congenital, acquired, or syndromic. Evaluation involves history, exam to locate any undescended testes, and sometimes imaging or labs. Treatment is usually surgical orchidopexy to position testes in scrotum.
The role of surgery in male infertility
There are several surgical procedures that can help treat male infertility by improving sperm production, delivery, or retrieval. Varicocele repair is the most common as it can improve semen parameters and pregnancy rates in 15% of infertile males. Vasectomy reversal has a 50-70% chance of pregnancy depending on if vasovasostomy or more involved vasoepididymostomy is needed. Ejaculatory duct obstruction may be treated with transurethral resection to relieve partial or complete blockage found in 1-5% of cases. For azoospermia, testicular sperm extraction techniques like microsurgical epididymal sperm aspiration combined with ICSI can achieve pregnancies in 76% of couples
Male Infertility
Male infertility can be caused by abnormalities in sperm morphology, motility, count, or the absence of sperm. Up to 50% of infertility cases involve male factors such as varicocele, undescended testes, infections, genetic issues, environmental toxins, or lifestyle factors. Treatment depends on the underlying cause but may include medications, surgery, assisted reproduction techniques like IVF, or cryopreservation of sperm for future use.

ANTENATAL_SCREENING_IN_FIRST_AND_SECOND_TRIMESTER.ppt
The document discusses antenatal screening tests in the first and second trimesters. In the first trimester, screening includes ultrasound markers like nuchal translucency, nasal bone, ductus venosus Doppler, and biochemical markers like PAPP-A and beta-hCG. Combined first trimester screening using these markers can detect around 85-90% of Down syndrome cases at a 5% false positive rate. In the second trimester, screening includes a genetic sonogram and biochemical markers, with a detection rate of around 82% for Down syndrome. The document provides details on measuring and interpreting various first trimester ultrasound markers and their association with chromosomal abnormalities.
From down syndrome screening to nipt
Prenatal screening and diagnosis of fetal abnormalities like Down syndrome is important given the significant morbidity, mortality, and financial costs associated with these conditions. New screening techniques using cell-free fetal DNA analysis from maternal blood, known as non-invasive prenatal testing (NIPT), have been shown to detect Down syndrome and other trisomies with over 99% accuracy and a false positive rate below 1%. While NIPT has advantages over traditional screening by being non-invasive and having higher detection rates and lower false positives, diagnostic testing through amniocentesis or CVS is still recommended for positive NIPT results to confirm the diagnosis. NIPT is becoming the standard of care for high risk pregnancies but further validation is still needed
iMGE Test™
The document discusses a genetic test called iMGE Test that analyzes miscarriage material to identify chromosomal defects that may cause pregnancy loss. The test uses next generation sequencing to analyze all chromosomes simultaneously and does not require cell culture, providing results for over 95% of cases. Identifying genetic causes can help guide family planning decisions and determine if preimplantation genetic diagnosis would be beneficial for couples seeking to avoid miscarriage in future pregnancies. The test is recommended after miscarriage for women over 35, those with a family history of genetic defects, or couples with a history of infertility or recurrent miscarriage.

Prenatal diagnosis
1. Prenatal screening and diagnostic techniques allow for the detection of fetal chromosomal abnormalities and genetic disorders. Techniques include first and second trimester screening, cell-free DNA screening, chorionic villus sampling, amniocentesis, and cordocentesis.
2. First trimester screening incorporates factors like maternal age, nuchal translucency, and biochemical markers. Second trimester screening analyzes maternal serum markers. Cell-free DNA screening analyzes fetal DNA in maternal blood. Invasive techniques like CVS and amniocentesis allow for karyotyping.
3. Genetic counseling is recommended to discuss family histories, risk factors, screening results

This document examines the effects of reproductive senescence on early egg development and embryonic viability in Drosophila. The main findings are:
1. Fecundity declines with age largely due to a decrease in pre-vitellogenic egg chambers and possibly retention of mature oocytes.
2. Fertility declines with age appear to result from increased abnormalities during blastoderm embryonic development, suggesting declining maternal provisioning causes developmental anomalies.
3. Embryos from old females with multiple reproductive episodes exhibited more abnormalities than those from old females with one episode, suggesting reproductive diapause may decrease but not eliminate age-related fertility decline.

Cryptochidism
Cryptorchidism refers to an undescended or maldescended testis. It occurs in 3% of full-term newborn boys, decreasing to 1% in boys aged 1 year. Risk factors include prematurity, low birth weight, twinning, and maternal estrogen exposure. Treatment is recommended at age 1, as spontaneous descent after this age is rare. Surgical exploration, known as orchidopexy, is required to bring undescended testes into the scrotum. Complications can include inadequate positioning, testicular atrophy, or accidental division of the vas deferens.
Seed, Soil and Beyond in Infertility Treatment
This document discusses factors that influence embryo implantation, including the quality of the embryo (seed) and endometrium (soil). It describes techniques for evaluating egg/sperm quality like oocyte scoring and assessing sperm structural defects and DNA damage. Methods of improving egg, sperm, and embryo quality are provided. The document also discusses endometrial receptivity, factors that influence it, and techniques like endometrial biopsy and receptivity array testing to assess the endometrium. Ways to improve endometrial lining through treatment of issues like thin endometrium are covered. Other external factors beyond the seed and soil that can also influence implantation are briefly mentioned. The conclusion emphasizes the importance of selecting the best embryo and
Pre implantation genetic diagnosis (pgd)
PGD combines IVF with genetic testing of embryos before implantation. It aims to identify genetic defects or chromosomal abnormalities to select healthier embryos. There are two main types of testing - PCR for single gene disorders and FISH/CGH for aneuploidies. While PGD can reduce risks of genetic diseases and miscarriages, it has limitations as not all abnormalities can be detected and the procedure carries a small risk of embryo damage. As techniques advance to test all chromosomes, PGD may help avoid more conditions but remains an expensive and specialized procedure currently only available at certain IVF clinics in India.
Ivf necessary element in gynaecology
1. The document discusses new concepts in infertility including updated WHO reference values for semen analysis, the use of ICSI for male factor infertility, and success rates varying based on the cause of infertility.
2. ICSI, where surgically retrieved sperm are injected into eggs, has become an established procedure for couples with male subfertility to have a biological child, with reassuring post-natal outcomes reported so far.
3. The success of IVF depends on the type of infertility, with male factor infertility seeing live birth rates around 40% and female factor infertility around 25%, higher than other causes of infertility.
Aneuploidy screening Aneuploidy screening
This document discusses antenatal screening for fetal aneuploidy. It introduces cytogenetics and explains that chromosomal abnormalities occur in approximately 1-2% of live births. The most common types of aneuploidy are trisomy 21, trisomy 18, trisomy 13 and sex chromosome aneuploidies. Screening methods discussed include biochemical screening, ultrasound screening for soft markers and structural abnormalities, and non-invasive prenatal testing using cell-free DNA. Biochemical markers analyzed include PAPP-A, beta-hCG, AFP, uE3, and inhibin A. Soft markers seen on ultrasound include increased nuchal translucency, absent nasal bone, ech
Prenatal diagnosis and fetal therapy
Prenatal diagnosis involves identifying fetal abnormalities through tests such as ultrasound scans and blood tests. Fetal therapy aims to improve the fetal environment through procedures like blood transfusions. First trimester screening for Down syndrome includes assessing the mother's age, measuring the fetal nuchal translucency, and testing maternal serum markers. Combining these factors provides a 79-87% detection rate. Additional markers like absent nasal bone and abnormal ductus venosus or tricuspid valve Doppler flows may further refine risk assessment. Genetic counseling is an important part of the screening and diagnostic process to help expectant families understand risks and make informed decisions.

Key indicators provided for different conditions include appearance, presence of cysts or calcifications, and blood flow patterns.
Recent advances in the management of ureteroceles in
Recent advances in the management of ureteroceles in children recommend a less invasive approach when possible. Ureteroceles result from delayed development of the ureter and cause sac-like dilations near the bladder. While traditionally treated with open surgery, studies now show that endoscopic puncture of the ureterocele is sufficient in many cases and has lower rates of reoperation compared to open excision. For ureteroceles without severe hydronephrosis, high grade vesicoureteral reflux, or bladder outlet obstruction, observation with periodic imaging may be preferable to surgery and allows most vesicoureteral reflux to resolve spontaneously. The goal of management is now to prevent
Tx on advanced, relapsing and castration resistance prostate cancer
This document provides an updated literature review from 2007-2010 on the treatment of advanced, relapsing, and castration-resistant prostate cancer. It summarizes findings on hormone therapies such as LHRH agonists and antagonists. It also discusses the use of antiandrogens, intermittent androgen deprivation therapy, and the timing of hormone therapy. Additionally, it reviews follow-up care, diagnosing relapse after curative treatment, recurrence treatment options, chemotherapy indications, and treatments for bone-related complications.
Penetrating injury
1. A 20-year-old male was stabbed in the abdomen with a 10 cm knife during a fight. He was hemodynamically stable on arrival to the emergency room.
2. The emergency physician attempted to examine the wound but could not determine if it penetrated the peritoneum due to its depth. A CT scan or FAST exam was recommended to check for internal bleeding before deciding on observation or surgery.
3. For hemodynamically stable patients with abdominal stab wounds, selective non-operative management is usually recommended initially. Further examination with CT scan is important to identify any internal bleeding before deciding on observation versus laparotomy.
2014 crpc,cspc how to treat
This document discusses emerging treatments for metastatic castration-sensitive prostate cancer and metastatic castration-resistant prostate cancer. It notes that intermittent androgen deprivation therapy may result in less resistance compared to continuous therapy, with no difference in survival but better quality of life. Chemotherapy such as docetaxel has been pushed earlier from metastatic castration-resistant prostate cancer to castration-sensitive prostate cancer. Drugs that block the androgen receptor pathway like abiraterone and enzalutamide have been approved for metastatic castration-resistant prostate cancer refractory to docetaxel. Bone targeted therapies such as denosumab and radium-223 can decrease bone-related events but have not been
