What Causes Free Peritoneal Fluid?

Patient Presentation
A pediatric resident was telling some other residents during their continuity clinic about some of the interesting radiology cases he had seen the previous week.
“Seems like I had a lot of abdominal cases. There was a CT case with blunt abdominal trauma where the spleen was ruptured and they had to take him to the operating room.
We had a teenage girl with pelvic pain who had a ruptured ovarian follicle and free fluid. And then there was the 4-year-old with nephrotic syndrome who had bad ascites.
I have a lot of good images to show in our pediatric case conference so everyone can learn.”

Discussion
Peritoneal fluid is normal. It decreases the friction of the peritoneum covering abdominal and pelvic organs and helps to protect them and allow their movement. A normal amount of peritoneal fluid is expected on radiological evaluation. Increased peritoneal fluid is a continuum and is concerning as a wide variety of pathological causes are associated with it such as abdominal trauma and appendicitis. At the far end of the scale is ascites that is the accumulation of free fluid more than 25 ml. It is usually associated with abdominal distension but fluid must accumulate before distension can occur and therefore it may be diagnosed before distension.

One prospective study of prepubertal healthy children found the normal volume of free peritoneal fluid had a mean and standard deviation of 4.7 +/- 5.65 mL for females and 1.9 +/- 3.11 mL for males. Maximum volume was 25 mL for females and 17 mL for males. Fifteen percent of females and 3% of males had more than 10 mL of fluid. There are also normal variations with menstrual cycles in women.

Abdominal trauma is an obvious cause of increased free peritoneal fluid and can include blood or other abdominal organ fluids. Usually there is a trauma history, but some intra-abdominal injuries can be difficult to diagnose and may occur after the acute injury and therefore are unrecognized immediately. There is a mortality rate as high as 8.5% with abdominal trauma. With blunt trauma, the spleen is the most common organ injured followed by the liver and pancreas. Bowel perforation can occur acutely or a few days later due to bowel compression and possible devascularization of the mesentery. Seat belt injuries are common causes of small bowel injuries particularly the jejunum. Free fluid and free air on radiologic studies are red flags for a surgical abdomen.

Free fluid is very common in appendicitis and occurs in up to 90% in some studies.

Ascites usually is caused by chronic diseases especially of the hepatic system, but also the cardiac and renal system or multiple organ systems. Ascites is less common in the pediatric age group as cardiac and liver disease are less common. However, nephrotic syndrome is a common cause of ascites.

A history of trauma, abdominal or pelvic pain, and abdominal distension are common reasons for radiographic evaluation. Computed tomography and/or abdominal ultrasound are used to assess for intra-abdominal pathology, free peritoneal fluid and free air. Management obviously depends on the history and cause. Blunt abdominal trauma is often treated conservatively but patients who are hemodynamically unstable or have free air are usually surgically explored as well as these with penetrating trauma. Patients with appendicitis or intra-abdominal abscess may be treated surgically. Management of medical pathology depends on the acute or chronic cause and secondary problems.

What is Dry Needling?

Patient Presentation
A 19-year-old female athlete came to clinic for her health supervision visit during the summer. She was a discus thrower completing at the NCAA Division I level. Overall her freshman year had gone well and she had no general medical concerns. She said that she had no specific injuries or problems with her training, but she said in retrospect she probably didn’t listen to her coach as well as she should have and overtrained early. She relayed that early in the preseason winter/spring she had had some upper back/lower cervical pain in her right side (throwing side). She had worked with the university physicians and trainers with a program of stretching, heat, and massage. “I had this one place that we couldn’t quite fix. They tried pressure on that too but it didn’t work. They then stuck some needles into the muscle a few times. That along with the other stuff, plus listening to my coach more, eventually stopped the pain in that spot.”

The pertinent physical exam showed a healthy muscular female with normal vital signs.
She had a normal examination including both shoulders and arms with no specific tight muscles or pain elicited on exam.

The diagnosis of a healthy female was made. The physician discussed how important it was to listen to her coaches regarding her training and to really do the physical therapy when it was recommended. “The pain in my shoulder and back was really bad for a while. It was hard and irritating to do my classes and regular activities. I don’t want to do that again. My coach has us doing a summer program and is checking in on us a few times a week. Believe me, I’m doing what they say including the physical therapy,” she said.

Discussion
Myofascial pain is pain from muscle or fascia, and usually associated with myofascial trigger points which are “…a highly localized, hyperirritable spot in a palpable, taut band of skeletal muscle fibers.” Trigger points are common reasons people, especially adults, seek relief in primary care or pain clinic settings. Athletes may also complain of pain caused by them. They are treated in a variety of ways, none of which used as a single method is successful for all individuals. Muscle “…stretching, massage, ischemic compression, laser therapy, transcutaneous electrical nerve stimulation, biofeedback, and pharmacological treatment…” are some options.

Learning Point
“With dry needling, a solid needle is passed through the skin into muscles, ligaments, tendons, subcutaneous fascia, and scar tissue to relieve or stimulate myofascial trigger points. The practitioner palpates the trigger point, places the need into the position over the target area on the skin, and taps or flicks the top of the needle to penetrate the skin. The needle may be inserted into a muscle to elicit a local twitch response, or into other connective tissue to elicit tissue relaxation. The needle is removed and placed into neighboring areas or allowed to remain in place for two minutes until the trigger-point sensitivity decreases.” It is called “dry” needling as the needles are solid and do not inject any fluid. Dry needling is also called Western acupuncture, medical acupuncture and intramuscular stimulation.

Dry needling is different than acupuncture. Dry needling is based on Western anatomy and physiological principles. Its mechanism is not understood, but may disrupt the trigger points, modulate nerves or some other effect. This appears to be the treatment the patient above had. Acupuncture is meant to stimulate acupoints and meridians in the body to help with the body’s energy flow. The underlying mechanism of its effect is not understood but may be due to changes in chemical and electrical activity within the body or other mechanisms. Acupuncture is also used for pain management and may be helpful in back, neck and osteoarthritis/knee pain. It is also used for some other problems such as nausea due to chemotherapy.

For acupuncture, the Federal Drug Administration “…requires that needles be sterile, non-toxic, and labeled for single use by qualified practitioners only.” Dry needling has similar requirements. Both are safe when performed by experienced practitioners using appropriate methods. Potential dry needling complications include bleeding or bruising in the site and pain are relatively common. Syncope can also occur. Less common complications include infection (local or deep usually with common skin organisms), injury to nerve, pneumothorax or cardiac tamponade.

Dry needling is offered by physicians (including pain and rehabilitation specialists), physical therapists and other similar health care practitioners. Efficacy data is difficult as randomized controlled trials do not represent real life situations and in most cases multiple interventions are being offered or have been tried by individuals. Dry needling may be used as part of a comprehensive strategy which could include exercise, soft tissue mobilization, postural interventions, ergonomic interventions and education about pain. A systemic review and meta-analysis concluded that while the data was low- to moderate- quality, dry needling was more effective than no treatment and sham dry needling for both shorter and intermediate term end points for pain relief and other functional outcomes.

How Long Does Neonatal Galactorrhea Last?

Patient Presentation
A 34-day-old male came to clinic for his well-child visit. He was the third child and the family had no concerns except for clear to white discharge from both breasts when touched or palpated. This occurred frequently and a small amount was produced. The breasts did not appear red, indurated or painful. The galactorrhea had been noted at his 1 week visit and the family had been told that it should disappear with more time. His neonatal screening test was normal including for hypothyroidism. His family denied him taking any medications. They also denied using or taking any medications in the home except for the mother’s prenatal vitamins. The family did have emollient creams but all were standard brands with usual ingredients. Specifically there were no known hormone exposures. The past medical history revealed a term male without significant prenatal or natal history.

The pertinent physical exam showed normal vital signs and growth parameters around the 50th percentile. He had palpable breast tissue under the areolas bilaterally that was about 2-3 cm in size. There were no irregularities of the tissue such as a discreet mass and the tissue seemed proportional between the two breasts. With minimal palpation, a small amount of a thin, whitish discharge without odor could be produced bilaterally. There was no surrounding erythema or edema and the infant did not seemed bothered by the palpation. The rest of his examination was normal.

The diagnosis of of a healthy male with bilateral galactorrhea was made. The pediatrician thought this was a little long to have galactorrhea due to maternal hormones, but also thought that the infant did not have neonatal mastitis, abscess, or breast mass. The infant also didn’t appear to in an environment where there were medications or exogenous hormones as the cause. His neonatal screening test was normal and he didn’t appear to have any stigmata of midline defects or genetic syndromes. Pediatric endocrinology was consulted and recommended to monitor the infant without further evaluation because this was bilateral and spontaneous in an otherwise healthy infant. It was thought this was still within the normal time period for transplacental maternal hormones as the cause.

The patient’s clinical course showed athis 2 month visit the family said that the discharge had stopped about 1 week after the last appointment and the breasts had decreased in size since that time.

Discussion
Galactorrhea is a milky discharge from the breast in a non-lactating female.

Neonatal galactorrhea is sometimes called “Witch’s Milk” based on ideas from the 17th century or earlier that witches would steal the milk for use in their magic. Infant breasts were often compressed to express the fluid and prevent its collection. During the 19th century, reports of breast inflammation and even abscess were reported because of this practice and it was strongly discouraged, and continues to not be recommended today.

Enlargement of neonatal breasts and galactorrhea, both for males and females, is felt to be usually due to transplacental maternal hormone stimulation and fetal hormones. This stimulation decreases rapidly after birth, but for some infants breast enlargement continues with or without galactorrhea. The ongoing cause is not totally certain.

Galactorrhea is most often seen in term infants as premature infants have little breast tissue and therefore breast enlargement and/or galactorrhea are not seen usually.

Nipple discharge that is usually benign is described as “bilateral, not spontaneous, and occurs with breast manipulation or stimulation, whereas suspicious discharge is usually unilateral, spontaneous and persistent. Bloody breast discharge is potentially worrisome for breast cancer however, pediatric breast cancer is exceedingly rare, and bloody discharge can be see due to stimulation and irritation.

Mastitis or breast abscess are again not very common in infants and children. However, with signs or symptoms of infection these problems must be considered. Neonatal mastitis has a high rate of concurrent bacteremia and usually is treated with systemic antibiotics. A review can be found here.

Prolactin is produced in the anterior pituitary lobe due to dopamine signaling. Prolactin then acts on the mammary gland to increase tissue and produce milk. It also has several other functions on the gonads, adipose tissue, insulin secretion and immune system. “…[S]tress, suckling, estrogens, [thyroid releasing hormone], vasoactive intestinal polypeptide… and oxytocin… act as stimulants of prolactin release directly into the anterior [pituitary] or by reducing the inhibitory action of dopamine.”

Causes of galactorrhea in the pediatric population include:

  • Transplacental maternal hormone
  • Hypothyroidism
  • Hyperprolactinemia
    • Pituitary adenomas
    • Polycystic ovarian syndrome
    • Estrogen
    • Oxytocin
    • Thyroid releasing hormone
    • Stress
    • Suckling
    • Vasoactive peptide
  • Medications
    • Antidopamineric
    • Antidepressants
    • Antipsychotics – a common cause
    • Anticonvulsants
    • Antiandrogens
    • Antihypertensives
    • Cholinomimetics
    • Estrogen
    • Opioids
    • Prokinetic agents
  • Other
    • Obesity (probably partly due to increased lipid conversion to estrogen)
    • Marijuana
    • Self-stimulation of breast tissue
    • Cancer – rare

Learning Point
Neonatal galactorrhea can last longer than usually thought. In a study of healthy newborns (N=640) examined from birth up to 12 weeks of age, 5.9% (N=38 infants) were found to have galactorrhea at some point. All of these infants were term infants and 55% were female. The incidence of galactorrhea was most common in the first 2 weeks of life (6.2% of 552 examinations), but still occurred at 2-5 weeks (3% of 265 examinations) and at 6-10 weeks (1.8% of 167 examinations) with decreasing incidence. One infant was examined at 12 weeks and still had persistent galactorrhea.

What Are Potential Complications of Tattooing?

Patient Presentation
A 15-year-old male came to clinic with his mother after she had noticed some redness and swelling around his ankle the previous day. He had been experimenting with giving himself a tattoo using pins and pen ink 3 days previously. He said that he had done this alone and had not shared any pins or needles with anyone. He said he had taken new pins from a container from his mother’s sewing basket, and had cleaned them by a match flame and then by sitting in alcohol. He had cleaned his skin with an iodine solution. He stated that, “It didn’t hurt too much and I think I did a good job with the small design. I’m not sure how much I like it though now.” He had re-cleaned the site afterwards and a few times a day since. The next day though it was redder but hadn’t really spread. His mother noticed the redness the night before. He denied wanting to hurt himself in any way including having no history of substance abuse, mental health issues or self-harm. He was doing well in school with the same social group. “I’m a pretty good artist and just wanted to see if I could give myself a small tattoo,” he stated.
The social history showed that his mother was a nurse and had been very upset when she found out about it. The past medical history showed that he was fully immunized.

The pertinent physical exam showed a healthy male with normal vital signs. There was a 2 cm black geometric drawing just about the lateral malleolus on the right ankle. There was a surrounding 3-4 cm ring of erythema but no significant swelling or induration. There was no streaking up the leg. There was full range of motion in the ankle and knee.

The diagnosis of a mild allergic local reaction vs mild cellulitis was made. Oral antibiotics were started. This incident was felt to be a very low risk of bloodborne pathogen exposure and so testing was not done at that time. He was also felt to not have significant psychosocial risk factors for self-harm or other high-risk behaviors. During confidential questioning the pediatrician confirmed the adolescent’s story The pediatrician discussed body art and the potential risks of tattoos. “Amateur tattoos have the highest risks of problems. Please don’t do that again or in the future. If you are going to get one in the future, please use a licensed business. They are professionals and can do it right if that is what you want to do. Remember tattoos are permanent and can be beautiful if done right. But there are real risks too. Please use your artistic talents in a different medium than tattoos for right now.” Three months later the adolescent had not done further tattooing but was doing ink drawings inspired by graphic artists.

Discussion
“Tattooing of skin via deposition of pigment particles and ink ingredients in the dermis changes normal skin into abnormal skin. Fortunately, this often causes no harm and no disease, although with important exceptions.” Tattoos can be inadvertent from road dirt, gunpowder, pencil graphite etc., but most are desired. Tattoos are common in many cultures and over time..They have been increasing in popularity in the United States over the past few years particularly with a younger, wider and more diverse population.

Newsweek reported an 18-country study in 2018 which showed 46% of Americans have a tattoo and the US and Sweden tied for the highest median number of tattoos at 4. Of those 14-29, 36% had a tattoo. Unfortunately many adolescents and young adults are not aware of the potential complications.

“If tattoos are placed in licensed parlors, infections are less likely to occur after tattooing than if they are placed by unlicensed individuals.” “Unfortunately, many tattoos are placed by amateurs, which makes the process much riskier. In these cases, antiseptic process may not be followed, leading to potential skin infections and transmission of bloodborne illnesses, such as hepatitis C or HIV.” Common sense recommendations if someone wishes to have a tattoo placed are to use a licensed business, and follow all appropriate after-care instructions scrupulously.

Tattoos sometimes can be removed but should be considered permanent before placement. Removal can be attempted including ablative, chemical, and mechanical, removal. Laser treatment is often used currently but has its own set of potential complications including burns. Removal can also be expensive. One study cited $49/square inch of tattoo/laser session. Multiple sessions are usually needed.

Learning Point
Tattoo complaints are not uncommon and occur around the time of tattoo placement or later. These include reactions such as inflammation, irritation, pruritis, or swelling. These can be worse with worse with sun exposure for people.

Tattoo complications include:

  • Infection
    • Potentially the most serious complication
    • Caused because contaminated equipment or ink, inadequate disinfection and secondary during healing due to irritation, pruritis etc.
    • Superficial problems are more common (e.g. impetigo, pustules), but can be worse with cellulitis or abscess problems. Bacteremia, sepsis or complications related to them such as endocarditis, erysipelas, and gangrene.
    • Common skin flora is the most common include Staphylococcus aureus and Streptococcus pyogenes. Other bacterial infections also include Clostridium species, E. coli, Pseudomonas species. Tuberculosis, non-tuberculosis mycobacterium and leprosy have been reported. Tetanus is not common because of vaccination but can occur. Fungus, parasites and spirochetes can also be inoculated.
    • Viral infections are probably of the most concern including bloodborne pathogens of Hepatitis B, Hepatitis C, and HIV. Other viruses causing local disease include Herpes, molluscum, warts and condyloma.
  • Allergic reaction
    • These are frequent and can be caused by inks, chemicals used, equipment or personal protective equipment
    • Long term inflammation, elevation, thickening, scaling, hyperkeratosis and even ulceration, necrosis and scarring.
      Can be more papular, nodular or more plaque-like

    • Latex allergy can be an early or late complication as particles from the tattooists’ latex gloves are introduced into the skin. These can cause problems later when latex is encountered including in foods that can cross-react
  • Neoplasms
    • Described in areas of tattoos and not know if this is causal or coincidence.
    • Tattoos over dermal lesions can make it difficult to monitor for malignant transformation
  • Provoked illness
    • Eczema
    • Psoriasis
    • Sarcoid
  • Other
    • Psychosocial problems
    • Ink problems – photosensitivity, migration, or metabolic conversion
    • Acute vasculitis
    • MRI burn
    • Syncope and falls around the procedure
