OBJECTIVE: To summarize the clinical and genetic characteristics of a child with 46,XX Ovotesticular disorder of sex development (46,XX OTDSD) due to copy number variation of SOX3 gene. METHODS: A 46,XX male patient presented at the Capital Center for Children's Health, Capital Medical University in November 2024 was selected as the study subject. Clinical data of the child was collected. Peripheral blood samples were taken from the child and his parents and subjected to trio whole-genome sequencing. Skewed X-chromosome inactivation was tested in the child and his mother. A literature review was carried out on 46,XX males associated with mutations of the SOX3 gene. This study was approved by the Medical Ethics Committee of the Hospital (Ethics No.: SHERLL2025056). RESULTS: The 10-year-old boy presented with hypospadias and cryptorchidism at birth. Chromosome analysis at one year and a half revealed a 46,XX karyotype. Gonadal biopsy showed testicular tissue, while ultrasound at the age of 10 detected ovotesticular tissue. Whole-genome sequencing identified a 660 kb duplication in the Xq27.1 region, which was derived from his mother. X-chromosome inactivation testing showed random inactivation in the child and mild non-random inactivation in the mother. Literature review has found 11 publications involving 15 patients (including our case), among whom 14 had a male social gender. They had primarily presented with hypospadias at birth but had no significant endocrine abnormalities. Most patients had experienced testicular failure after puberty. SOX3 related 46,XX males are mainly caused by de novo duplications, although a few maternal carriers had been discovered. CONCLUSION Duplication of the SOX3 gene probably underlay the pathogenesis is this 46,XX male. Individuals with 46,XX SRY negative male phenotypes should be routinely screened for SOX3 gene variants. Structural variations of the SOX3 gene can lead to complete or partial sex reversal in 46,XX individuals with minimal impact on intellectual and motor development, as well as other endocrine hormones.

In the Philippines, the rate of sexually transmitted infections (STIs) remains high, and statistics show that the highest prevalence is among individuals between the ages of 15 and 24 years old. Unlike Human Immunodeficiency Virus (HIV), other common STIs, such as gonorrhea, syphilis, HPV and herpes are not well discussed.

A descriptive cross-sectional study was conducted to determine the knowledge, awareness and misconceptions of STIs and their practices among men and women aged 15-24 in Sampaloc, Manila. Convenience sampling was conducted among 15- to 24-year-old residents from Barangay 466, excluding healthcare professionals. Sets of questions were adapted from other knowledge, attitudes and practices (KAP) research studies and underwent cross-cultural validation. Questions were also translated and validated into the Filipino language. Data gathering was conducted using self-administered surveys disseminated through online posting and in-community, as well as face-to-face recruitment.

Among the 104 respondents, HIV remained the most recognized STI (99%), while less than half were aware that chlamydia and hepatitis B are STIs. The most common misconception about STI transmission includes the sharing of food and drinks. In terms of prevention, more than half of the participants believed that oral contraceptive pills can prevent STIs. With regards to attitude, 43.3% of the participants disagreed that watching/reading pornographic materials can contribute to risky sexual practices. Among sexually active participants, 19% do not use condoms, and 65% of them do not get tested annually.

In conclusion, the findings from this study reveal a concerning gap in KAP related to STIs among participants aged 15-24 Filipinos. It is recommended that efforts should be directed towards targeted education campaigns and interventions to empower young individuals with accurate information and foster a responsible approach to sexual health.

Introduction: Swyer syndrome (46, XY gonadal dysgenesis) is a rare disorder of sex development, characterized by a phenotypic female with streak gonads and hypergonadotropic hypogonadism. It presents with primary amenorrhea and delayed puberty. Overlapping clinical features with Turner syndrome may cause diagnostic uncertainty, highlighting the role of karyotypic evaluation in diagnosis. Case: A 35-year-old phenotypic female was first evaluated at age 27 during admission for an acute viral illness, when incidental findings of primary amenorrhea, short stature (height 131 cm), webbed neck, pectus excavatum, and absent secondary sexual characteristics raised suspicion of Turner syndrome. She had hypertension, with initial imaging suggesting coarctation of the thoracic aorta. CT angiography showed focal narrowing of the descending aorta; multidisciplinary review favored aortic folding, and she was managed conservatively. Endocrine evaluation demonstrated hypergonadotropic hypogonadism, with markedly elevated follicle-stimulating hormone (FSH 108.6 IU/L) and luteinizing hormone (LH 23.16 IU/L) in the presence of low estradiol levels. Pelvic imaging revealed an atrophic uterus with absence of bilateral ovaries, consistent with gonadal dysgenesis. Karyotypic analysis was performed, demonstrating a 46, XY genotype with confirmed SRY gene presence, establishing the diagnosis of Swyer syndrome. DEXA scan demonstrated osteoporosis, in keeping with prolonged hypogonadism. She was commenced on hormone replacement therapy, resulting in the development of secondary sexual characteristics and regular withdrawal bleeding. She remains under structured multidisciplinary follow-up, with endocrine-led management of hypothyroidism and osteoporosis, alongside cardiology follow-up and gynecological surveillance. Conclusion This case highlights the diagnostic complexity of disorders of sex development with overlapping phenotypes and the need for re-evaluation when clinical progression is atypical. Diagnosis enables hormone replacement therapy for induction of secondary sexual characteristics and preservation of bone health. Integration of clinical, biochemical, and genetic data within a multidisciplinary framework is essential to achieve diagnostic accuracy and optimize outcomes.

Angiomyolipoma with epithelial cysts (AMLEC) is a rare subtype of angiomyolipoma that may closely mimic both malignant and benign neoplasms. We report a case of AMLEC in an 18-year-old female presenting with acute flank pain and radiologic suspicion for malignancy. This case highlights the diagnostic challenges posed by AMLEC, emphasizes its characteristic histopathologic and immunohistochemical features, and reviews current concepts regarding its pathogenesis. This case represents the first documented case of AMLEC in the Philippines.

Introduction: Short stature and delayed puberty characterize Turner syndrome (TS). The 2024 international clinical practice guidelines recommend growth hormone (GH) for latediagnosed patients if epiphyses remain open. For patients with remaining growth potential, initiating GH alongside low-dose estrogen effectively balances linear growth with the need for timely pubertal induction. Case: A 15-year-old female, born prematurely at 6 months gestation, presented with delayed puberty, primary amenorrhea, and short stature. Examination revealed a height of 122 cm (<5th percentile), weight of 26 kg, with no syndromic facies, and Tanner stage 1. Investigations confirmed hypergonadotropic hypogonadism. Metabolic screening, including thyroid, renal, and liver profile, was normal. Her baseline insulin-like growth factor 1 (IGF-1) was low at 117.5 ng/mL (127.5–541.5). Karyotyping confirmed mosaic TS (45,X/46,Xr). Her skeletal bone age was delayed at 12 years, indicating a viable window for linear growth prior to complete epiphyseal fusion. Subcutaneous GH was initiated at 0.3 mg up titrated to 1.2 mg (0.45 µg/kg) daily over 4 weeks, then 1.35 mg (50 µg/kg) daily at month 5. Low-dose oral estradiol (0.5 mg three times weekly) was introduced for pubertal induction at month 4. After 9 months of combined GH and estrogen therapy, the patient achieved a height increment of 6 cm, reaching 128 cm without an adverse event. To achieve the clinical target of a 10–15 cm increment in the first year, her GH dose was further increased to 1.50 mg (55 µg/kg) daily. She showed an appropriate biochemical response with IGF-1 increased to 40.2 nmol/L (16.4–67.8) with a total height gain of 6 cm over the first 9 months of GH therapy. Conclusion Concomitant GH and estrogen therapy in late-diagnosed TS successfully induced clinically significant height gain. This dual approach maximized the limited window for linear growth, without delaying pubertal induction and compromising patient’s psychosocial well-being.

Introduction: X-linked hypophosphatemia (XLH) is a rare genetic disorder caused by PHEX mutations, characterized by chronic hypophosphatemia and renal phosphate wasting, resulting in skeletal, dental, and extra-skeletal complications. To date, no data from Malaysia are currently available on clinical characteristics or health-related quality of life (HRQoL) in paediatric patients. Methodology: This cross-sectional study evaluated HRQoL among children and adolescents with XLH, using validated PROMIS (PatientReported Outcomes Measurement Information System) instruments, sociodemographic and clinical factors associated with HRQoL. This includes children and adolescents with confirmed XLH followed up at Universiti Malaya Medical Centre (UMMC) between November 2024 and March 2025. Results: Seventeen patients were analyzed (76.5% female and 23.5% male). The mean age at symptom onset was 2.82 ± 2.42 years, with a mean age at diagnosis of 5.21 ± 3.29 years. All patients continued to have musculoskeletal complications, including short stature (76.5%), bowing of legs (76.5%), bone/joint pain (47.1%), muscle pain (47.1%), and dental complications (52.9%). Serum alkaline phosphatase improved significantly (p = 0.011); persistent hypophosphatemia and ongoing musculoskeletal manifestations indicated suboptimal disease control. Elevated parathyroid hormone levels and an increase in urine calciumto-creatinine ratio (p = 0.020) lead to secondary hyperparathyroidism and nephrocalcinosis. Adherence to conventional therapy was poor. Non-adherence was associated with worse pain outcomes (higher pain interference [p = 0.037] and greater pain intensity [p = 0.025]). PROMIS scores revealed severely impaired mobility (mean T-score 31.31 ± 12.17), increased fatigue (mean T-score 54.22 ± 7.60), and high pain interference (mean T-score 63.11 ± 9.50). Larger household size was also strongly associated with higher pain intensity (p = 0.004). Conclusion Malaysian children and adolescents with XLH continue to have significantly poor HRQoL, particularly in mobility, fatigue, and pain. These findings highlight the need for access to targeted therapies, such as burosumab, to improve long-term outcomes and QOL in XLH patients.

Prostate cancer(PCa) is a common malignant tumor among elderly men, with high incidence and mortality rates worldwide, posing a serious threat to human health. Traditional treatments face limitations, highlighting the urgent need for novel therapeutic strategies. Recent studies on the regulatory mechanisms of micro ribonucleic acid(microRNA, miRNA) in tumor development has identified miRNA as new targets for PCa diagnosis and treatment. Traditional Chinese medicine(TCM), with its multi-mechanism, multi-target, and multi-pathway regulatory properties, shows promising potential in miRNA-based PCa therapy. This review summarized recent findings on miRNA' roles in PCa and research progress of TCM intervention and found that a variety of miRNA played important regulatory roles in cell differentiation, proliferation, apoptosis, invasion, metastasis, immune microenvironment, and drug resistance, and their potential as biomarkers for PCa diagnosis, prognosis, and therapy, indicating the potential to be a biomarker for the diagnosis, prognosis evaluation, and treatment of PCa. The review concluded that the active components of TCM(terpenoids, flavonoids, alkaloids, and others) and compounds(Yishen Tonglong Decoction, Shenhu Decoction, Zhoushi Qiling Decoction, Fuzheng Yiliu Decoction, and Qilan Formula) could regulate the expression of their downstream target genes by acting on specific miRNA and affect the above biological behaviors of PCa cells, thus playing a role in the treatment of PCa. This review aims to provide a theoretical basis for miRNA as potential biomarkers and therapeutic targets for PCa and suggest new avenues for further development of targeted therapy strategies against miRNA.

We report a case involving an 85-year-old man who underwent laparoscopic radical prostatectomy for prostate cancer in 2011. During follow-up, he required long-term use of a penile clamp to manage urination due to permanent severe stress incontinence. In February 2023, he presented with a painless cystic mass in the scrotum. Upon pressing the mass with hand, fluid drained from the external urethral orifice, causing the mass to shrink in size, although it returned to its original size a few hours later. Urography and cystoscopy showed a globular urethral diverticulum located anteriorly. The patient underwent surgical excision of the diverticulum along with urethroplasty. Postoperatively, the urinary stress incontinence persisted, but he declined any further surgical intervention. An artificial urinary sphincter is currently the first-line treatment for male urinary incontinence. However, devices such as penile clamps can serve as an alternative when considering surgical suitability or cost. It is important to note that these devices can lead to serious complications such as urethral erosion, stricture, or diverticulum. Therefore, caution is advised when using such devices, and they should be removed periodically at short intervals.

Testicular tumor is the most common solid malignancy in males under 40 years of age. This malignancy is known to have a negative impact on male fertility. Therefore, several techniques for sperm retrieval have been proposed, including microdissection testicular sperm extraction (mTESE). The objective of this study was to review the literature on the outcomes of oncological (Onco)-mTESE at the time of radical orchiectomy. We conducted a comprehensive literature search through PubMed, Scopus, and Cochrane Central Controlled Register of Trials. Only studies reporting ex vivo mTESE in patients with testicular tumor were considered. Twelve papers met the inclusion criteria and were included in this review. Tumor size was identified as the sole preoperative factor influencing spermatogenesis. The considered studies demonstrated a satisfactory success rate for Onco-mTESE, associated with a similarly valid percentage of live healthy births through assisted reproductive technology. Currently, no comparison has been made between Onco-mTESE and conventional Onco-TESE, hence further assessment is required. In cases where the tumor completely replaces the cancer-bearing testicle, a contralateral micro-TESE may be a viable alternative. However, the surgeon should evaluate associated risks and benefits preoperatively. In conclusion, Onco-mTESE at the time of radical orchiectomy appears to be a promising therapeutic option for young patients with testicular tumors. Nevertheless, additional studies are necessary to achieve a definitive conclusion.
