From smart pills to augmented intelligence, technology has presented the health care industry with a host of options to improve medication adherence and safety.

The latest innovations to improve medication adherence

**Editor's Note** Please note that starting January 1, 2025, we will be switching to an online-exclusive publication process. This will allow us to publish case submissions quicker without having to deal with the variables that come along with print publication. All cases will still be eligible for print publication consideration, but publication in our print magazine is not guaranteed and will be up to the editor's discretion. 

Do you have a puzzling pediatric case that you’d like to share with the readers of 

We are looking for intriguing diagnoses that have stumped the experts—a diagnostic “Puzzler”—to help our physicians enhance their day-to-day practices. If you have such a story to tell, tell us.

Here’s what to do: Before you begin, we suggest that first you review the Puzzler 

https://www.contemporarypediatrics.com/case-studies

. Please note the specific style required for writing Puzzler manuscripts.

Next, prepare a draft of your case, including a summary of the presenting symptoms, a case overview, a 

table of the differential diagnosis (MANDATORY)

, and the special aspects of your case that qualify it as a Puzzler, and send it to us. Please note that the differential diagnosis table should also be discussed in the body text. We’ll review your draft and let you know what you need to add or revise before we send the manuscript to peer review for evaluation.

Puzzlers vary in length, and we suggest a minimum of 1,200 words up to a maximum of 2,000 words, but that is because of the complexity of some cases and whether some patients returned for many assessments before their diagnoses were determined. Also, some authors describe the pathophysiology of the differentials in great detail. Please also note no more than 3 authors are allowed per article.

What's most important is to show us the process that you used to analyze the case, including:

Why you decided to order certain tests and why you did not order others.

Peer consultations or why you elected to contact other specialists.

Lab values including vital signs or blood tests.

Labs and values if your patient was attended to in the emergency department or other hospital departments such as radiology or neurology.

Discussion related to the possible diagnoses.

Final diagnosis, treatment, prognosis, and follow-up.

Remember to indicate numbered citations within the body of the text and include a complete list of corresponding literature/references at the end of the manuscript. (Do not use any citation management programs or unlink them.) 

Limit references to 25. No references (unless it is a seminal study) can be older than 10 years.

We prefer primary research as references, but some cases are so obscure that authors will need to pull from a variety of sources. However, 

. Be advised that peer reviewers are adamant that the disease/disorder you describe was actually diagnosed and not determined by index of suspicion on the basis of ruling out various differentials. We use AMA11 as our publication style, which uses superscript citation numbers and a corresponding numbered reference list. Please create your citations and references in this style.  Check this recent article posted online at 

https://www.contemporarypediatrics.com/view/the-rx-of-adhd

 for examples of reference style. IMPORTANT NOTE WITH AMA 11TH EDITION: PLEASE PUT DOI OR WEBSITES/URLS AT THE END OF THE REFERENCE LINE.

When you send your draft manuscript, also 

. These image files must be high-resolution jpg or tiff files (minimum of 300 dpi) and as large in size as possible. We suggest a minimum of 7 horizontal inches. The images must be original photos with clear permissions to use, not images from copyrighted sources. Send as separate attachments with your e-mail submission; do not embed images into your manuscript document.

After we receive your manuscript, our editors and peer reviewers will review your draft and let you know if we accept your submission for publication. 

Puzzler is one of the departments for which we receive the most submissions, so it may be several months after submission before you receive feedback from us.

If we do accept your submission for publication, we will contact you with further instructions.

A 13-year-old female with a history of iron deficiency anemia presented with altered mental status preceded by 5 days of headache, vomiting, nausea, and worsening somnolence that was not responsive to flumazenil, naloxone, or ammonia salts. She had a Glasgow coma scale of 12 and was drowsy with no cranial nerve deficits, or other abnormal physical examination findings. Laboratory evaluation showed microcytic anemia (hemoglobin 7.7 g/dL and MCV (mean corpuscular volume):64.7, lymphocytosis, and mildly elevated liver enzymes [Aspartate Aminotransferase (AST) 52, Alanine Transaminase (ALT) 110] otherwise her electrolytes and kidney function were normal. 

Urine toxicology, Tylenol level, Salicylate level, alcohol level thyroid studies, iron studies, hepatitis panel were normal. Urine pregnancy and COVID tests were negative. Head computed tomography (Head CT) showed mild hydrocephalus, and brain magnetic resonance imaging (MRI) showed increased signal folia and compression of the lower portion of the fourth ventricle and foramen of Magendie. 

She then had an emergency external ventricular drain placed (EVD) by pediatric neurosurgery, and the team started her on high-dose steroids and intravenous immunoglobulin (IVIG). On the third day of admission, she developed new onset left-sided facial drooping, drooling, downbeat nystagmus, and difficulty following commands. An emergent subcortical craniectomy and decompression, duraplasty, and cerebellar biopsy were performed. A cerebellar biopsy was performed due to findings on brain MRI.

A boy aged 10 years presented to the outpatient office with a history of painful nodules on the plantar surface of his bilateral feet 8 to 10 hours after spending time in a hot tub. He was unable to bear weight or put on socks and shoes due to his pain. The photos were taken soon after the painful and red papules appeared. The lesions affected the whole plantar aspect of both feet. Over the following 4 days, the nodules became less painful and red. 

Medical advice was sought on the fifth day of symptoms, and by this time, the child was improving clinically. He was stable with subcutaneous, mildly painful, fleshy nodules mostly populating the medial arch of the foot. His remaining clinical examination results were within a normal range. Further questioning of the child’s mother revealed that other children exposed to the hot tub experienced painful feet but without lesions. 

Due to the patient’s improving symptoms and the self-limiting nature of the illness, no tests or labs were ordered as the child was not acutely ill. No peer consultations or specialists were utilized.

New research led by Geetika Kennady, MD, FAAP, shows 10.6% of newborns have iron deficiency, supporting a push for earlier screening.

The necessity for iron deficiency screening at birth with Geetika Kennady, MD, FAAP

At the 2025 Pediatric Academic Societies Meeting in Honolulu, Hawaii, Geetika Kennady, MD, FAAP—neonatologist at Thomas Jefferson University and Nemours Children's Health—presented findings from her team's prospective study highlighting the prevalence of iron deficiency (ID) at birth and the need for early screening.

"In the past, everybody used to think that babies are never born iron deficient because they scavenge all the iron for mom," Kennady explained. "But now, more and more studies have come out saying that this scavenging doesn't happen in all babies." Kennady emphasized that factors such as prematurity, placental insufficiency, maternal anemia, diabetes, hypertension, smoking, and alcoholism disrupt fetal iron transfer.

The study prospectively analyzed 396 infants by collecting umbilical cord blood samples and assessing complete blood counts, reticulocyte hemoglobin equivalent (Ret-He), serum ferritin, serum iron, and transferrin saturation (TS). ID was defined as serum ferritin ≤50 ng/mL or TS ≤30%. Overall, 10.6% of infants were found to be iron deficient, including 11.2% of high-risk infants and 8.1% of no-risk infants, at birth.

Further stratification revealed 8.3% of preterm infants, 10.4% of small-for-gestational-age (SGA) infants, 13.5% of infants born to mothers with diabetes, 12.9% with hypertensive disorders of pregnancy (HDP), and 11.7% with maternal anemia were iron deficient at birth. 

"With these high prevalence rates, we should be prioritizing early screening and identification of iron deficiency at birth," Kennady stated. "Studies have shown that if babies are iron deficient, there is long-term neurodevelopmental impairment. Treatment is a pretty low-risk treatment, widely available, low-cost treatment, which is iron supplementation," added Kennady. 

Plans are underway for larger studies and randomized trials to determine whether universal screening is warranted.

Geetika Kennady, MD, FAAP has no relavent disclosures.
