Gynecomastia in Infants, Children, and Adolescents

Childhood Obesity: An Updated Review

BACKGROUND

Childhood obesity is an important and serious public health problem worldwide.

OBJECTIVE

This article aims to familiarize physicians with the evaluation, management, and prevention of childhood.

METHODS

A PubMed search was conducted in May, 2021, in Clinical Queries using the key terms "obesity" OR "obese". The search included clinical trials, randomized controlled trials, case-control studies, cohort studies, meta-analyses, observational studies, clinical guidelines, case reports, case series, and reviews. The search was restricted to English literature and children. The information retrieved from the above search was used in the compilation of the present article.

RESULTS

Most obese children have exogenous obesity characterized by a growth rate for height above the 50th percentile, normal intelligence, normal genitalia, and lack of historical or physical evidence of an endocrine abnormality or a congenital syndrome. Obese children are at risk for dyslipidemia, hypertension, diabetes mellitus, non-alcoholic fatty liver disease, obstructive sleep apnea, psychosocial disturbances, impaired quality of life, and shorter life expectancy. The multitude of serious comorbidities necessitates effective treatment modalities. Dietary modification, therapeutic exercise, and behavioral modification are the fundamentals of treatment. Pharmacotherapy and/or bariatric surgery should be considered for obese individuals who do not respond to the above measures and suffer from a serious comorbid condition.

CONCLUSION

Childhood obesity, once established, is often refractory to treatment. Most treatment programs lead to a brief period of weight loss, followed by rapid re-accumulation of the lost weight after the termination of therapy. As such, preventive activity is the key to solving the problem of childhood obesity. Childhood obesity can be prevented by promoting a healthy diet, regular physical activity, and lifestyle modification. Parents should be encouraged to get involved in school and community programs that improve their children's nutritional status and physical activity.

Applications of indocyanine green (ICG) fluorescence technology in open surgery: preliminary experience in pediatric surgery

Background

Indocyanine green fluorescence technology (ICG) in pediatric minimally invasive surgery has undergone an important improvement in the last 5 years. However, its use in open surgery is still limited. In this paper, we aim to report our preliminary experience with Rubina® lens ICG fluorescence technology in combination with the IMAGE1 S™ system from KARL STORZ in open excision of masses in children.

Methods

The records of 18 patients undergoing open surgery for head, neck and thorax masses between September and November 2022 were retrospectively reviewed. Rubina® lens ICG fluorescence technology system was used in all the cases. In 10 cases we adopted the holding arm system and in 8 cases the hand-held technique. Data about patients' demographics, surgery and outcomes were collected and analyzed through the following criteria: mass localization, intraoperative time (min), ICG administration (ml), intraoperative complications, postoperative complications.

Results

A total of 18 patients were operated: 4 thyroglossal duct cysts, 3 supraorbital cysts, 2 neck masses, 2 pre-auricular and 2 scalp cysts, 2 gynecomastias, 2 lymphangiomas, 1 nose mass. In all the cases, intralesional injection of 0.5-1 ml of ICG solution was performed peri-operatively. Mean operative time was 58.4 min (35-134 min). Postoperative complications included seroma formation in 2 cases. Surgical pathology reports confirmed complete mass excision in all the cases.

Conclusion

Based on our preliminary experience, ICG fluorescence guided surgery using Rubina® lens system was very helpful also in open surgery procedures. Rubina® lens system permits to have a very low complication rate, a time-saving surgery, a real time reliability of anatomic structures and an excellent clinical safety. In our experience, holding arm system seems more comfortable than hand-held system. However, further cases need to be performed to evaluate the exact role and to identify new indications of this technique in open pediatric surgical procedures.

A retrospective cohort study of tamoxifen versus surgical treatment for ER-positive gynecomastia

BACKGROUND

Gynecomastia is a common condition in clinical practice. The present study aimed to review the clinical data of ER-positive gynecomastia patients treated by tamoxifen (TAM) versus surgery and discussed the clinical effects of the two treatment strategies.

METHOD

We retrospectively collected the clinical indicators of patients with unilateral or bilateral gynecomastia who received treatment at our hospital between April 2018 and December 2021. Depending on the treatment received, the patients were divided into TAM and surgery groups.

RESULT

A total of 170 patients were recruited, including 91 patients in TAM group and 79 patients in surgery group. The age of the patients differed significantly between the TAM and surgery groups (P < 0.01). The estrogen level was closer in patients with stable and progressive disease, but significantly different in patients of glandular shrinkage in TAM group (P < 0.01). The proportion of patients achieving stable disease was higher among those with clinical grade 1-2. Among patients classified as clinical grade 3, the proportion of patients achieving glandular shrinkage of the breast was higher after TAM treatment (P < 0.05). The age and length of hospital stay were significantly different in patients undergoing open surgery than minimally invasive rotary cutting surgery and mammoscopic-assisted glandular resection (P < 0.01). Patients had significantly different complications including mild postoperative pain, hematoma, nipple necrosis, nipple paresthesias and effusions among the surgery subgroups (all P < 0.05). The estrogen level and the type of surgery were significantly different between the surgical recurrence and non-recurrence subgroups (P < 0.05). The difference in the thickness of glandular tissues upon the color Doppler ultrasound also reached a statistical significance between the two groups (P = 0.050). An elevated estrogen level was a factor leading to TAM failure. Among surgical patients, the thickness of glandular tissues, estrogen level, and type of surgery performed were risk factors for postoperative recurrence (all P < 0.05).

CONCLUSION

Both treatment strategies can effectively treat gynecomastia, but different treatment methods can benefit different patients. TAM treatment is more beneficial than surgery for patients who cannot tolerate surgery, have a low estrogen level, and are clinical grade 1-2. Surgery treatment is better than TAM for patients of clinical grade 3. Different surgery options may lead to different complications. Patients with a greater glandular tissue thickness and a higher estrogen level were shown to have a higher risk of recurrence.

Endoscope-Assisted Minimally Invasive Surgery for the Treatment of Glandular Gynecomastia

BACKGROUND

Gynecomastia (GYN) is the most common benign disease in males. A vacuum-assisted biopsy is a minimally invasive surgical technique for GYN treatment that achieves satisfactory aesthetic results. However, due to the operation under non-direct vision, it is difficult to localize the bleeding points and assess the residual glandular tissue. Endoscopy was applied to observe the operative field after subcutaneous mastectomy. The present study aimed to recommend our initial experience in glandular GYN with endoscope-assisted minimally invasive subcutaneous mastectomy.

METHODS

A total of 34 patients diagnosed with glandular GYN (50 breasts), treated with endoscope-assisted minimally invasive surgery at The First Affiliated Hospital with Nanjing Medical University between June 2018 and June 2020, were enrolled in this study. According to Simon's classification of the breast, 10 was grade I, 25 was grade IIA, and 15 was grade IIB. The characteristics of patients, operative data, postoperative complications, cosmetic outcome, and patient satisfaction were recorded.

RESULTS

Endoscope-assisted minimally invasive mastectomy was performed successfully in all cases. The operative duration of the operation was 55-120 min/side. The total weight of the resected tissue of the 50 breasts was 55-350 g, and the blood loss was 10-105 mL/breast. Endoscopy detected five breasts with bleeding and three with residual glandular during the operation. Postoperative bleeding occurred in 1 breast, subcutaneous seroma in 3 breasts, dysesthesia of the nipple-areolar complex in 2 breasts, and skin redundancy in a bilateral patient. None of the patients experienced severe pain, infection, nipple necrosis, and nipple retraction, a saucer-like deformity. With a median follow-up of 21 months, all patients were satisfied with their cosmetic outcome (100%), and no recurrence occurred.

CONCLUSION

Endoscope-assisted minimally invasive mastectomy could be used as a feasible technique for the treatment of glandular GYN.

Prevalence of endocrine disorders among children exposed to Lavender Essential Oil and Tea Tree Essential Oils

Background

Lavender essential oil and tea tree essential oil have become popular ingredients in personal care and household products in recent decades. Questions regarding the safety of these oils in pediatric populations have been raised, proposing a link between these essential oils and endocrine disruption in children, specifically prepubertal gynecomastia. To date, no epidemiological studies have been conducted to evaluate this proposed link.

Methods

This is a cross sectional study conducted among parents of children in the United States to identify the prevalence of endocrine disruption in children aged 2-15 years old. This study also evaluates the potential for a relationship between the exposure of lavender essential oil and tea tree essential oil products and endocrine disrupting outcomes.

Results

In 556 children with a mean age of 6.33 (SD = 3.92), prevalence of endocrine disruption was .016 (SD = 0.13). No cases of prepubertal gynecomastia were identified in either group, and prevalence of precocious puberty, delayed puberty, growth hormone deficiency, and hypothyroidism were all consistent with population norms. Total risk of endocrine disorders among those exposed (0.0194) did not differ from the risk of those unexposed (0.0069). The risk ratio was 2.796 (95% CI: 0.352, 22.163, P = .458).

Conclusion

Children who were regularly exposed to lavender or tea tree essential oils experienced the same risk of endocrine disorders as those who were not exposed.

Complications and Quality of Life following Gynecomastia Correction in Adolescents and Young Men

BACKGROUND

Persistent adolescent gynecomastia negatively affects health-related quality of life. Surgery results in psychosocial improvements, but the effects of postoperative complications on health-related quality of life are unknown. The authors examined whether complications following adolescent gynecomastia surgery impact postoperative health-related quality of life.

METHODS

Patients aged 12 to 21 years who underwent surgical correction of unilateral/bilateral gynecomastia between 2007 and 2019 were enrolled (n = 145). Relevant demographic and clinical data were obtained from medical records. Fifty-one patients completed the following surveys preoperatively, and at 6 months and 1, 3, 5, 7, 9, and 11 years postoperatively: 36-Item Short-Form Health Survey (Version 2), Rosenberg Self-Esteem Scale, and the 26-item Eating Attitudes Test.

RESULTS

Within a median period of 8.6 months, 36 percent of breasts experienced at least one complication. The most common were residual tissue (12.6 percent), contour irregularities (9.2 percent), and hematomas (7.8 percent). Patients reported significant postoperative improvements in self-esteem and in seven health-related quality-of-life domains (Physical Functioning, Role-Physical, Bodily Pain, Vitality, Social Functioning, Role-Emotional, and Mental Health) at a median of 33.3 months. Postoperative survey scores did not vary by grade or procedure, or largely by body mass index category or complication status. However, patients aged younger than 17 years at surgery scored significantly higher than older patients in the Short-Form Health Survey Vitality and Mental Health domains postoperatively.

CONCLUSIONS

Health-related quality-of-life improvements are achievable in adolescents through surgical correction of persistent gynecomastia. Postoperatively, patients largely experienced similar health-related quality-of-life gains irrespective of complication status, grade, surgical technique, or body mass index category. Minor postcorrection complications are but do not appear to limit postoperative health-related quality-of-life benefits.

Gynecomastia with rare granulomatous lobular mastitis: a case report and literature review

This study was performed to describe a rare case of granulomatous lobular mastitis (GLM) that was successfully treated with bromocriptine in a male patient with gynecomastia and hyperprolactinemia. A 20-year-old man presented with a 1-year history of breast enlargement and galactorrhea. Physical examination revealed bilateral breast enlargement, porous discharge, and a 3-cm left breast lump in the 10-o’clock quadrant. Magnetic resonance imaging of the brain showed a 1.2-mm pituitary tumor. Laboratory analysis revealed hyperprolactinemia with low serum testosterone and elevated prolactin and estradiol levels. The lump in the left breast was examined by ultrasonography and mammography, and a core needle biopsy revealed chronic inflammation. The patient’s galactorrhea and breast lump disappeared after 3 months of treatment with bromocriptine at 2.5 mg once a day. His serum prolactin level also normalized. Following a review of this case, the patient was diagnosed with gynecomastia with hyperprolactinemia complicated by rare GLM. To the best of our knowledge, this is the first reported case of concurrent gynecomastia and GLM.

Breast development in pediatric patients from birth to puberty: physiology, pathology and imaging correlation

Breast tissue undergoes a series of changes from birth to puberty. The majority of the changes are transient, related to physiological hormonal changes. Although the breast is identical in both sexes at birth, its histology and development will eventually differ. It is important for radiologists to have a basic understanding of endocrinological changes and appearance on imaging to avoid potential pitfalls, particularly on ultrasound, which is the primary modality used to evaluate the breast.

Gynecomastia: a study to assess how students perceive this disease

Background: Gynecomastia is a benign proliferation of the glandular male breast tissue. Gynecomastia etiology might be physiological or non-physiological such as medications, chronic diseases (e.g. hypogonadism), or steroid supplements. Aim: The purpose of this study was to assess the knowledge and understanding of gynecomastia among medical students and which resources were used to gain their understanding regarding the disease. Methods: Data for this qualitative, questionnaire-based cross-sectional study was collected on the basis of our own study objectives and from available questionnaires with similar objectives. The questionnaire was composed of 26 questions divided into many items that were recorded including sociodemographic data, gynecomastia symptoms, and holistic perception of the problem by the students. Exclusion criteria included those who refused to participate in the study and did not complete the questionnaire. Statistical tests were taken significant at p-value ≤0.05. All analyses were performed using SPSS, version 21. Results: A total of 200 medical students participated in this study, among them more males than females (64% vs. 36%). We observed that medical students had significantly more moderate knowledge with teachers as their source of information on gynecomastia (p=0.028) while with books (p=0.005) and internet (p=0.041) as their sources of information they had significantly more a higher level of knowledge. Conclusions: Medical students have overall insufficient knowledge about gynecomastia especially in physical examination and treatment aspects. Therefore, gynecomastia is to be considered more thoroughly in the curriculum.

Gastroesophageal reflux in children: an updated review

Background

Gastroesophageal reflux is a common disorder in pediatrics. Clinicians should be familiar with the proper evaluation and management of this condition.

Objective

To provide an update on the current understanding, evaluation, and management of gastroesophageal reflux in children.

Methods

A PubMed search was performed with Clinical Queries using the key term ‘gastroesophageal reflux’. The search strategy included meta-analyses, randomized controlled trials, clinical trials, observational studies, and reviews. The search was restricted to the English literature and the pediatric age group.

Results

Regurgitation is the most frequent symptom of gastroesophageal reflux and is present in nearly all cases. Gastroesophageal reflux occurs normally in infants, is often physiological, peaks at 4 months of age, and tends to resolve with time. Gastroesophageal reflux disease occurs when gastric contents reflux into the esophagus or oropharynx and produce troublesome symptom(s) and/or complication(s). A thorough clinical history and a thorough physical examination are usually adequate for diagnosis. When the diagnosis is ambiguous, diagnostic studies may be warranted. A combined esophageal pH monitoring and multichannel intraluminal esophageal electrical impedance device is the gold standard for the diagnosis of gastroesophageal reflux disease if the diagnosis is in doubt. In the majority of cases, no treatment is necessary for gastroesophageal reflux apart from reassurance of the benign nature of the condition. Treatment options for gastroesophageal reflux disease are discussed.

Conclusion

In most cases, no treatment is necessary for gastroesophageal reflux apart from reassurance because the condition is benign and self-limiting. Thickened feedings, postural therapy, and lifestyle changes should be considered if the regurgitation is frequent and problematic. Pharmacotherapy should be considered in the treatment of more severe gastroesophageal reflux disease for patients who do not respond to conservative measures. Proton pump inhibitors are favored over H₂-receptor antagonists because of their superior efficacy. Antireflux surgery is indicated for patients with significant gastroesophageal reflux disease who are resistant to medical therapy.

Gynecomastia after euthyroidism restoration in a patient with type 1 diabetes and Graves' disease

In patients with autoimmune disease, gynecomastia should not be considered as 1 of the first signs of hyperthyroidism, rather it is a breast pathology that can be present even when euthyroidism restoration is achieved. It is unknown whether the autoimmune nature of thyroid disorders or simply the hyperthyroidism effects breast changes.

Oxytocin and Gynecomastia: Correlation or Causality?

Oxytocin has been administered to patients with autism spectrum disorder (ASD) in order to improve social skills, communication, and manage repetitive behaviors in the context of research trials. The majority of the studies focus on acute administration; thus, the effectiveness and potential side effects of chronic administration remain unknown. The main goal of this case report is to highlight the importance of the safety parameters for the chronic use of intranasal oxytocin administration. In a single case conducted in our outpatient clinic, one adolescent (15 years old) received intranasal oxytocin (24 IU) twice per day, in accordance with the recommended doses for this age group that varies from 8 - 25 IU twice per day. After three weeks of treatment, the patient presented with gynecomastia. While it is not certain that the gynecomastia was oxytocin-induced, this case highlights the importance of developing optimal regimens for chronic oxytocin administration, with a particular focus on safety parameters.
