BACKGROUND: Postpartum hypogalactia (PH) is prominent during lactation and may negatively impact the mother\'s or infant\'s health. Acupuncture is widely used to increase maternal breast milk production. However, the effects of acupuncture on PH remain unclear. Therefore, this review aimed to evaluate the efficacy and safety of acupuncture in individuals with PH.
METHODS: Articles on potentially eligible randomized controlled trials (RCTs) on acupuncture for PH published from database inception to October 2023 were retrieved from the PubMed, Web of Science, Cochrane Library, EMBASE, EBSCO, Scopus, China National Knowledge Infrastructure, Chinese Biomedical Literature Database, WanFang, and VIP databases. Two reviewers independently screened the records, extracted essential information, and evaluated the methodological quality of the RCTs using the revised Cochrane risk-of-bias (RoB) tool. The primary outcome was a change in serum prolactin (PRL) levels before and after treatment. Secondary outcomes included milk secretion volume (MSV), total effective rate (TER), mammary fullness degree (MFD), and exclusive breastfeeding rate (EBR). Meta-analyses were performed using RevMan v5.4. Finally, the quality of evidence was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluation tool.
RESULTS: This study included 19 RCTs involving 2,400 participants. The included studies were classified as having an unclear to high RoB. Our findings indicated that, overall, acupuncture showed a significant effect in increasing serum PRL levels (standardized mean differences [SMDs] = 1.09, 95% confidence interval [CI]: 0.50, 1.68), MSV (SMD = 1.69, 95% CI: 0.53, 2.86), TER (relative risk [RR] = 1.25, 95% CI: 1.10, 1.42), and EBR (RR = 2.01, 95% CI: 1.07, 3.78) compared to that in the control group; however, no difference in MFD (SMD = 1.17, 95% CI: -0.09, 2.42) was observed. In the subgroup analysis, acupuncture combined with Chinese herbs or conventional treatment was significantly more effective in increasing serum PRL levels, MSV, and TER than did Chinese herbs or conventional treatment alone. Moreover, acupuncture alone resulted in significantly higher serum PRL levels compared to Chinese herbs; however, this benefit was not observed for TER and MFD. The quality of evidence was critically low.
CONCLUSIONS: Acupuncture may effectively increase milk secretion in women with PH. However, owing to the low quality of evidence, further rigorously designed studies are warranted to confirm our findings.

Prolactin-secreting pituitary neuroendocrine tumors (PitNETs) are more common in women. Male patients may also have few symptoms and have macroadenomas extending outside the sella turcica. This study aimed to report the results of cabergoline treatment in male patients with prolactin-secreting PitNET. The study included nine male patients aged 26-65 years (median, 46 years) diagnosed with prolactin-secreting PitNETs. The age at onset, prolactin values, tumor size, symptoms, and treatment were assessed. The mean prolactin value at the initial presentation was 2734.6 ng/mL, and the mean maximum tumor diameter was 40.4 mm. Visual field disturbance was the most common symptom (44.4%), followed by headaches (33.3%), asymptomatic symptoms (11.1%), and galactorrhea (11.1%). Eight patients responded to cabergoline treatment with normalization of prolactin levels and tumor shrinkage. One patient did not respond to the cabergoline treatment and required surgical intervention. There were no cases of cerebrospinal fluid leakage. Cabergoline was found to be an effective treatment for male prolactin-secreting PitNETs.

Raw area on the breast, especially when it is lactating, can lead to complications, including hyperprolactinemia and development of milk fistulae. A 25-year-old female presented with raw area over the left breast after 2 months of childbirth. She had history suggestive of necrotizing disease, which had primarily been managed elsewhere with debridement and dressings. We excised the raw area and applied split thickness skin grafts with minimal meshing. Bulky dressing prevented breastfeeding. On postoperative day 3, there were blebs containing milk underneath the graft. The blebs were drained and oral cabergoline was administered for 3 months. The skin graft healed well. If expression of breast milk is not possible then suppression of lactation should be considered before definitive cover of the raw area of breast.

Hypophysitis is an extremely rare inflammatory disease that can mimic the clinical and radiological features of a pituitary adenoma. In this case report, we describe a 45-year-old woman with secondary xanthogranulomatous hypophysitis (XGH) who presented with signs of a pituitary macroadenoma. The patient complained of headaches, visual impairment, and amenorrhea-galactorrhea syndrome. Her physical examination was normal. Laboratory investigation revealed corticotropin, thyrotropin, and gonadotropin deficiencies. She also had low visual acuity in her right eye and an altered visual field. Pituitary magnetic resonance imaging revealed an intra and suprasellar mass measuring 13 × 11 × 16 mm, with hemorrhagic necrosis, that was having a discrete mass effect on the patient\'s optic chiasm and pituitary stalk. The patient was treated with hydrocortisone and levothyroxine, and then transferred to the Neurosurgery department for total transsphenoidal resection of the mass. Histological examination of the tumor permitted a diagnosis of XGH of a remodeled Rathke\'s pouch cyst to be made. Systemic conditions such as tuberculosis, sarcoidosis, and other granulomatous diseases were excluded. The etiopathogenesis of XGH remains poorly characterized, but it may be a progressive form of lymphocytic hypophysitis or a remodeled Rathke\'s pouch cyst. Screening for autoimmune pathology and systemic diseases is essential to guide appropriate management.

BACKGROUND: Treatment of hyperprolactinemia with ergoline dopamine agonists (DAs) can be complicated by intolerance and resistance.
OBJECTIVE: This study examines the efficacy and tolerability of the nonergot DA ropinirole for the long-term treatment of hyperprolactinemia.
METHODS: Twelve hyperprolactinemic women were treated with ropinirole in a 6-month, open-label, dose-escalation trial; 7 of the 12 continued treatment in an extension study for up to 17 months. Ropinirole doses were uptitrated to achieve normal prolactin (PRL) levels, restore menses, and eliminate galactorrhea.
RESULTS: Two of the 12 participants were DA naive; 6 of 12 were ergot DA intolerant; and 1 of 12 had known ergot DA resistance. Baseline PRL levels were 126.2 ± 41.4 ng/mL (SEM). Ropinirole was uptitrated from 0.125 to 0.25 mg/h to a median total daily dose (TDD) of 2 mg/d (1-4 mg/d [interquartile range]). PRL normalization was achieved in 50% of the participants (5 with microadenomas and 1 with idiopathic hyperprolactinemia) at a median effective TDD of 1 mg/d. Of the patients achieving PRL normalization, 83% were ergot DA intolerant. A persistent partial biochemical response (PRL reduction >50% from baseline) was achieved in 17% of the participants. During treatment, menses resumed in 67% of amenorrheic patients; galactorrhea resolved in 67%. Mild adverse effects were reported in 92% of participants; however, ropinirole was not discontinued because of intolerance even among the 50% of individuals with a prior history of ergot DA intolerance and resultant medication discontinuation.
CONCLUSIONS: These data demonstrate the efficacy and tolerability of ropinirole for the treatment of hyperprolactinemia in patients with microprolactinomas and idiopathic hyperprolactinemia and suggest ropinirole may represent a novel therapeutic alternative for treating hyperprolactinemic disorders in patients with ergot DA intolerance.

Although these agents are used frequently, prospective data comparing serotonin/dopamine antagonists/partial agonists (SDAs) in youth regarding prolactin levels and sexual adverse effects (SeAEs) are scarce.
Youth aged 4 to 17 years, SDA-naive (≤1 week exposure) or SDA-free for ≥4 weeks were followed for ≤12 weeks on clinician\'s-choice aripiprazole, olanzapine, quetiapine, or risperidone. Serum prolactin levels, SDA plasma levels, and rating scale-based SeAEs were assessed monthly.
Altogether, 396 youth (aged 14.0 ± 3.1 years, male participants = 55.1%, mood spectrum disorders = 56.3%, schizophrenia spectrum disorders = 24.0%, aggressive-behavior disorders = 19.7%; SDA-naive = 77.8%) were followed for 10.6 ± 3.5 weeks. Peak prolactin levels/any hyperprolactinemia/triple-upper-limit-of-normal-prolactin level were highest with risperidone (median = 56.1 ng/mL/incidence = 93.5%/44.5%), followed by olanzapine (median = 31.4 ng/mL/incidence = 42.7/76.4%/7.3%), quetiapine (median = 19.5 ng/mL/incidence = 39.7%/2.5%) and aripiprazole (median = 7.1 ng/mL/incidence = 5.8%/0.0%) (all p < .0001), with peak levels at 4 to 5 weeks for risperidone and olanzapine. Altogether, 26.8% had ≥1 newly incident SeAEs (risperidone = 29.4%, quetiapine = 29.0%, olanzapine = 25.5%, aripiprazole = 22.1%, p = .59). The most common SeAEs were menstrual disturbance = 28.0% (risperidone = 35.4%, olanzapine = 26.7%, quetiapine = 24.4% aripiprazole = 23.9%, p = .58), decreased erections = 14.8% (olanzapine = 18.5%, risperidone = 16.1%, quetiapine = 13.6%, aripiprazole = 10.8%, p = .91) and decreased libido = 8.6% (risperidone = 12.5%, olanzapine = 11.9%, quetiapine = 7.9%, aripiprazole = 2.4%, p = .082), with the least frequent being gynecomastia = 7.8% (quetiapine = 9.7%, risperidone = 9.2%, aripiprazole = 7.8%, olanzapine = 2.6%, p = 0.61), galactorrhea = 6.7% (risperidone = 18.8%, quetiapine = 2.4%, olanzapine = 0.0%, aripiprazole = 0.0%, p = .0008), and mastalgia = 5.8% (olanzapine = 7.3%, risperidone = 6.4%, aripiprazole = 5.7%, quetiapine = 3.9%, p = .84). Postpubertal status and female sex were significantly associated with prolactin levels and SeAEs. Serum prolactin levels were rarely associated with SeAEs (16.7% of all analyzed associations), except for the relationship between severe hyperprolactinemia and decreased libido (p = .013) and erectile dysfunction (p = .037) at week 4, and with galactorrhea at week 4 (p = .0040), week 12 (p = .013), and last visit (p < .001).
Risperidone, followed by olanzapine, was associated with the largest prolactin elevations, with little prolactin-elevating effects of quetiapine and, especially, aripiprazole. Except for risperidone-related galactorrhea, SeAEs did not differ significantly across SDAs, and only galactorrhea, decreased libido, and erectile dysfunction were associated with prolactin levels. In youth, SeAEs are not sensitive markers for significantly elevated prolactin levels.

BACKGROUND Juvenile-type granulosa cell tumors (JGCTs) are a rare subtype of sex cord stromal tumor with a characteristic histology that is commonly found in the first 3 decades of life. It most commonly presents with symptoms of hyperestrogenism, which may present as precocious pseudopuberty or as menstruation-related symptoms, allowing for early detection of the tumor. CASE REPORT We present the case of a 12-year-old girl who presented to her primary care provider (PCP) with secondary amenorrhea with intermittent abdominal pain, who underwent an ultrasound for further evaluation, which revealed a large incidental pelvic mass. She was admitted to the Emergency Department (ED) and had findings of galactorrhea and hyperprolactinemia on examination. Imaging studies demonstrated a large ovarian mass measuring 15.0×9.0×18.8 cm that was resected, and subsequent pathology results showed JGCT stage 1A. CONCLUSIONS Prognosis of granulosa cell tumors (GCT) largely depends on its initial size, stage at diagnosis, residual tumors after surgery, and the subtype of GCT. If the patient is of reproductive age, fertility-sparing surgical options must be considered and patients must be regularly monitored for recurrence. JGCTs can present with minimal to no symptoms of precocious puberty in young girls but may present with amenorrhea, which may be considered normal for their developmental age. Although JGCTs are rare, they are important to include in differential diagnoses of younger female patients with abdominal pain, especially if accompanied by hormonal irregularities.

OBJECTIVE: To analyse the causes of hyperprolactinaemia in patients with symptoms compatible with hyperprolactinaemia evaluated in a primary care setting.
METHODS: A retrospective study of all patients tested for serum prolactin levels between 2019 and 2020 in 20 primary care centres at the Hospital Ramón y Cajal in Madrid. Hyperprolactinaemia is defined as a serum prolactin>19.4ng/ml in men and >26.5ng/ml in women. Aetiology is grouped into physiological (pregnancy, lactation, inadequate venipuncture, macroprolactinaemia), pharmacological, pathological (hypothalamic and/or pituitary diseases, chronic renal failure, primary hypothyroidism), and idiopathic.
RESULTS: In 1630 patients tested for serum prolactin, 30.7% (n=501) had hyperprolactinaemia. Of these 501 patients, 89.6% were females. 149 patients were referred to the Endocrinology Department and 164 to the Gynaecology Department. Aetiological diagnosis of hyperprolactinaemia was achieved in 411 out of 501 cases. The most frequent cause of hyperprolactinaemia was pharmacological, in 39.1%. The second more frequent cause was idiopathic (29%) and less common were inadequate venipuncture extraction (13.4%), tumour (8.5%) and macroprolactinaemia (3.9%). Patients with tumoural hyperprolactinaemia presented higher serum prolactin levels (87.0±80.19 vs 49.7±39.62ng/ml, P=0.010). In addition, symptoms, such as galactorrhoea (33.3% vs 16.5%, P=0.018), and headache (25.7% vs 13.3%, P=0.045), were more frequent than in patients of the other aetiological groups.
CONCLUSIONS: Hyperprolactinaemia is common among patients evaluated in a primary care setting with symptoms of hyperprolactinaemia, but more than 50% of cases are due to pharmacological treatments or improper sample extraction. It is necessary to establish referral protocols to specialised medicine to optimise healthcare resources and avoid unnecessary studies.
