Klinefelter's Syndrоme Pаthоlоgy Extrа copy of X chromosome in individuаls who are biologically male due to sex chromosome nondisjunction during maternal/paternal meiotic division Most common 47, XXY karyotype Less Common Greater/lesser numbers of X chromosome 48,XXXY, 49,XXXXY, 46,XY/4,XXY mosaicism karyotypes Greater number X chromosomes-> greater phenotypic abnormalities Most common sex chromosome abnormality; occurs in 1/1000 live births Leads to primary hypogonadism, impaired cognitive development Complications Increased risk for psychiatric disorders, autism Problems with social interactions Delayed speech, language competence Predisposition to Disease May result in death Pulmonary Chronic bronchitis, emphysema Thromboembolic cancers Germ cell tumors, breast cancer (morbidity much higher in individuals with Klinefelter), non-Hodgkin lymphoma Leg ulcers Diabetes mellitus Signs and Symptoms Newborns who are biologically male, phenotypically normal (e.g. with male external genitalia) Tall stature with decreased upper to lower extremity ratio due to decreased levels of testosterone, unsuppressed follicle stimulating hormone (FSH), luteinizing hormone (LH) Decreased testes size Increased levels of serum FSH, LH Variably decreased levels of serum testosterone--> breast enlargement (increased risk of breast cancer); reduced facial, body hair; infertility Diagnosis Lab Results Blood/Urine tests Abnormal hormone levels: High FSH/LH and Low total testosterone Karyotype analysis Other Diagnostics Postnatally, observe signs of physical clinical manifestations Evaluation for infertility, enlarged breast tissue May present with cryptorchidism (undescended testes) Treatment Medications Testosterone replacement therapy; stimulate changes that typically occur during puberty (e.g. facial, body hair growth; increased muscle mass, penis size; improved bone density) Surgery Breast tissue removal Psychotherapy Psychological counseling Other Interventions Sex chromosome changes can't be corrected Supportive therapy minimizes adverse effects, improves quality of life Speech therapy Fertility treatment
Testiculаr tоrsiоn is а surgicаl emergency that results frоm the twisting of the spermatic cord, which leads to reduced blood flow to the testicle. Timing of symptoms is very important because 8-12 hours after onset increases the likelihood of significant ischemic damage. The physical exam should focus on the abdomen and inguinal area to rule out other causes of scrotal pain, such as an inguinal hernia. Cremasteric reflex is usually absent in patients with testicular torsion, but it does not rule out torsion, if present. Ultrasound with Doppler is usually done to evaluate blood flow if testicular torsion is suspected. A urinalysis should also be done to look for pyuria and bacteriuria, which is more consistent with epididymitis. Manual detorsion can be attempted if the patient’s pain is controlled and tolerable. This is attempted via the “open book” rotation technique. If successful, there will be sudden pain relief, the testicle will change orientation, and it will drop lower in the scrotum.
