Learn about Breast Tumor in Teenage Girls





If  teenage girls and women during their early reproductive years found tumor in their breast. The first one we must think about Fibroadenoma mammae (FAM). Because Fibroadenoma is the most common breast tumor in this age. They are rarely seen in women after the age of 40 or 45. Fibroadenomas are benign solid tumors composed of stromal and epithelial elements. Clinically, they may increase in size over a period of several months. They easily palpable and may be lobulated form. 

Fibroadenomas do not have malignant potential, although neoplasia may develop in the epithelial elements within them, just as in epithelium elsewhere in the breast. Cancer in a newly discovered fibroadenoma is exceedingly rare.

On excision, fibroadenomas are well-encapsulated masses that may detach easily from surrounding breast tissue. A tissue diagnosis is required to rule out malignancy.

Fibroadenoma has two subtypes. The first one is Giant Fibroadenoma that attains an unusually large size, typically greater than 5 cm. And latter is Juvenile Fibroadenoma that occurs in adolescents and young adults and histologically is more cellular than the usual fibroadenoma. Although these lesions may display remarkably rapid growth, surgical removal is curative.

Bacterial Vaginosis



Definition

Bacterial vaginosis (BV) has previously been referred to as nonspecific vaginitis or Gardnella vaginitis.

It is an alteration of normal vaginal bacterial flora that results in the loss of hydrogen peroxide producing lactobacilli and an overgrowth of predominantly anaerobic bacteria.

Anaerobic bacteria can be found in less than 1% of the flora of normal women. In women with Bacterial Vaginosis, however, the concentration of anaerobes, as well as Gardnerella vaginalis and Mycoplasma hominis, is 100 to 1,000 times higher than in normal women. Lactobacilli are usually absent.

Risk Factors

It is not known what triggers the disturbance of normal vaginal flora. It has been postulated that repeated alkalinization of the vagina, which occurs with frequent sexual intercourse or use of douches, plays a role. After normal hydrogen peroxide producing lactobacilli disappear, it is difficult to reestablish normal vaginal flora, and recurrence of Bacterial Vaginosis is common.

Diagnosis
It is diagnosed on the basis of the following findings :
·         A fishy vaginal odor
·         Vaginal discharge are present ( gray and thinly coat the vaginal walls).
·         The pH of these secretions is higher than 4.5 (usually 4.7 to 5.7).
·         Microscopy of the vaginal secretions reveals an increased number of clue cells, and leukocytes are conspicuously absent.
·         The addition of KOH to the vaginal secretions releases a fishy, amine like odor.
·         Culture of G. vaginalis is not recommended as a diagnostic tool because of its lack of specificity.
Complication
Women with Bacterial Vaginosis are at increased risk for :
·         Pelvic inflammatory disease (PID)
·         Post-abortal PID
·         Postoperative cuff infections after hysterectomy
·         Abnormal cervical cytology.

Pregnant women with Bacterial Vaginosis are at risk for :
·         Premature rupture of the membranes (PROM)
·         Preterm labor and delivery
·         Chorioamnionitis
·         Post-cesarean endometritis.

Treatment
The effective treatment are :
1.      Metronidazole is the drug of choice for treatment of Bacterial Vaginalis.
This antibiotic with excellent activity against anaerobes but poor activity against lactobacilli.
Dose :
·         Oral : 500 mg twice a day for 7 days.
·         Gel : Metronidazolegel, 0.75%, one applicator (5 g) intravaginally once or twice daily for 5 days.
2.      Clindamycin is effective regimen in treating Bacterial Vaginosis.
Dose :
·         Oral : 300 mg twice daily for 7 days.
·         Cream : Clindamycin 2% one applicator full (5 g) intravaginally at night before sleep for 7 days.

Treatment of the male sexual partner has not been shown to improve therapeutic response and therefore is not recommended

Dysmenorrhea


Definition

Dysmenorrhea is a common gynecologic disorder affecting as many as 50% of menstruating women.

Primary dysmenorrhea refers to menstrual pain without pelvic pathology, usually appears within 1 to 2 years of menarche, when ovulatory cycles are established. The disorder affects younger women but may persist into the 40s.

Secondary dysmenorrhea is defined as painful menses associated with underlying pathology, usually develops years after menarche and can occur with anovulatory cycles.

Symptoms

The pain of primary dysmenorrhea usually begins a few hours before or just after the onset of a menstrual period and may last 48 to 72 hours with suprapubic cramping, and may be accompanied by lumbosacral backache, radiating down the anterior thigh.

Nausea, vomiting, diarrhea, and rarely syncopal episodes.

Signs

The vital signs are normal. The suprapubic region may be tender to palpation. Bowel sounds are normal, and there is no upper abdominal tenderness and no abdominal rebound tenderness. Bimanual examination at the time of the dysmenorrheic episode often reveals uterine tenderness; however, severe pain does not occur with movement of the cervix or palpation of the adnexal structures. The pelvic organs are normal in primary dysmenorrhea

Diagnosis

To diagnose primary dysmenorrhea, it is necessary to rule out underlying pelvic pathology and confirm the cyclic nature of the pain. The differential diagnosis of secondary dysmenorrhea includes primary dysmenorrhea and noncyclic pelvic pain. Whereas the diagnosis of primary dysmenorrhea is based on history and presence of a normal pelvic examination,

The diagnosis of secondary dysmenorrhea may require review of a pain diary and an ultrasound examination or laparoscopy or hysteroscopy or both. During the pelvic examination, the size, shape, and mobility of the uterus; the size and tenderness of adnexal structures; and the nodularity or fibrosis of uterosacral ligaments or rectovaginal septum should be assessed. Cervical studies for gonorrhea and chlamydia and, if relevant, a complete blood count with an ESR, are helpful to rule out subacute salpingo-oophoritis. If no abnormalities are found, a tentative diagnosis of primary dysmenorrhea can be established.

Treatment

· Prostaglandin synthase inhibitors, or NSAIDs, are effective for the treatment of primary dysmenorrhea The medication may be contraindicated in patients with gastrointestinal ulcers or bronchospastic hypersensitivity to aspirin. Side effects are usually mild and include nausea, dyspepsia, diarrhea, and occasionally fatigue.

· Acupuncture or transcutaneous electrical nerve stimulation (TENS), may also be useful.

· Spinal manipulation.

In clinical trials, however, it has not been found to be effective. Methods used only rarely to treat primary dysmenorrhea include surgical laparoscopic uterine nerve ablation and presacral neurectomy.

Ectopic Pregnancy


Definition

Ectopic pregnancy is a potentially life-threatening condition in which the embryo implants outside the uterine cavity.

Incidence

The incidence of ectopic pregnancy has more than quadrupled in the USA. Currently, 20 cases occur per 1000 pregnancies.

Ectopic pregnancies account for 10% of pregnancy-related maternal deaths in th USA. Most are attributed to hemorrhage and are potentially preventable.

Risk Factors

· High risk : tubal corrctive surgery, tubal sterilization, previous ectopic pregnancy.

· Moderate risk : infertility, previous genital infection, multiple partners.

· Slight risk L previous pelvic or abdominal surgery, smoking, douaching, sexual intercourse before 18 years.

Signs and Symptoms

· Pain : remain the most common symptom. Most patients also report abnormal vaginal bleeding, usually spotting or slight intermittent bleeding.

· Patients with acute rupture present with sharp, tearing, pelvic pain associated with fainting.

· Tachycardia, hypotension and cervical motion tenderness.

Diagnosis

· A Thorough history and physical examination are essential. The extent should be dictated by the severity of symptoms at presentation.

· Serial quantitative levels of the β-hCG levels are important.

· Transvaginal ultrasonography can detect an intrauterine gestational sac.

· Culdocentesis may be performed in the emergency room and can quickly confirm the presence or free blood in the peritoneal cavity.When 10 mL of non clotting blood is aspirated the test is positive.







Management

Medical Therapy

Metotrexate chemotherapy is effective treatment for select patient with small, unrupteured ectopic pregnancies. Metotreaxate (MTX) side effects (nausea, vomiting) are generally mild. Localized, mild abdominal pain is a common complaint following MTX due to serosal irritation. However, patients should be closely monitored since rupture is a known risk.

Surgical Therapy

· In a patient who is hemodynamically unstable due to rupture of the ectopic pregnancy, emergency surgery (usually laparatomy with or without removal of the rupture fallopian tube) remains the treatment of choice.

· In a hemodynamically stable patient with a ruptured tubal pregnancy, laparoscopy and either removaql (salpingectomy) or segmental resection of the tube may be necessary.

· In a hemodynamically stable patient with an unreuptured tubal pregnancy, conservative surgery with tubal salvage.

· Oophorectomy is only indicated to achieve hemostasis.

Evaluation strategies

· The history provieds a description of the nature, intensity, and distribution of the pain. However, imprecise localization is typical with intra-abdominal processes.

· The physical examination includes a comprehensive gynecologic examination. Specific attention should be paid to reproducing the pain symptoms.

· Culturesm serum chemistry and electrolyte evaluations, or ultrasonography and other imaging studies may be indicated.

· Specialized diagnostic studies based on the presumptive diagnosis may be require consultation with other specialist in anesthesiology, orthopedics, neurology or gastroenterology.
