Chinese Journal of Medical Genetics 2026;43(3):228-233
Hereditary fibrosing poikiloderma with tendon contractures, myopathy, and pulmonary fibrosis (POIKTMP) is a rare autosomal dominant genetic disorder. It may also involve many other organ systems, leading to complications such as exocrine pancreatic insufficiency, liver dysfunction, lymphedema, and developmental delay. The FAM111B has been determined as the pathogenic gene associated with POIKTMP syndrome, whose protein product plays a critical role in regulating essential cellular processes including DNA repair and replication, cell cycle progression, apoptosis, nuclear transport, and telomere length maintenance. This article has provided a comprehensive review for the genetic basis of POIKTMP syndrome and its correlation with various phenotypes, which may offer insights for basic research and clinical diagnosis of this disease.

2.Bullous hemorrhagic dermatosis in a 65-year-old Filipino woman secondary to enoxaparin: A case report.
Acta Medica Philippina 2026;60(1):92-95
Bullous hemorrhagic dermatosis (BHD) is a rare cutaneous manifestation characterized by tense hemorrhagic bullae that appear at sites distant from low molecular weight heparin (LMWH) injections, typically within seven days of exposure. As of March 2022, only 94 cases have been reported. It most commonly affects elderly males with predisposing factors for thromboembolism, such as carcinoma, and usually involves the extremities.
This case highlights the importance of maintaining a high index of suspicion for bullous hemorrhagic dermatosis (BHD) in patients receiving low molecular weight heparin, even beyond the typical 7-day window and in demographics not commonly affected. Early recognition and prompt discontinuation of the offending agent, as demonstrated in this atypical presentation involving a Filipino elderly woman with multiple comorbidities and no malignancy, can lead to favorable outcomes. Clinicians should be aware of this rare but reversible complication to avoid misdiagnosis and ensure appropriate management.

Acta Medica Philippina 2025;59(18):111-116
Weber-Christian Disease (WCD), or relapsing febrile nodular panniculitis is a rare form of subcutaneous fat inflammation commonly affecting women aged 40-75 years old. It is rarer in children with only 1 previously reported case in the Philippines. It presents as erythematous nodules, frequently affecting the lower extremities. There is no standard treatment, but reportedly improves with steroid therapy, cyclosporine, and immunomodulators.
This is a case of a 12-year-old-female, who presented with a 4-month history of palpable facial nodules, thigh pains, and recurrent fever. Work-up for hypersensitivity reaction, autoimmune condition, hematologic problem, or infectious etiology yielded unremarkable findings, and corresponding management had no significant response. Patient developed firm lesions on the abdomen which was sent for biopsy and showed results consistent with WCD. Steroid, hydroxychloroquine, and topical indomethacin were then started and noted gradual improvement of the lesions. Patient was then discharged improved with lesions noted to progressively decrease in size and with no appearance of newer lesions upon follow-up.
WCD is a rare form of nodular panniculitis, more so in the younger age group. It is characterized by presence of cutaneous lesions associated with systemic symptoms. Skin biopsy is necessary to confirm its diagnosis. Visceral organ involvement and failure to respond to treatment may result to poor prognosis, and occasionally leads to death.

INTRODUCTION:
The COVID-19 pandemic has changed care provision models, with a rapid increase in the adoption of telemedicine to reduce in-person visits. Although there are many benefits to teledermatology, there are also factors that hinder its widespread adoption. We aimed to examine patients' perceptions of teledermatology to identify the barriers to its adoption.
METHODS:
A prospective study was conducted from 15 June to 14 August 2020. Patients were invited to complete a questionnaire in an outpatient dermatology clinic via direct approach by clinical staff or posters posted at the door of consultation rooms.
RESULTS:
Out of 2,276 clinic attendances, 997 survey responses (43.8%) were collected over a 3-month period. When asked if they would change their subsequent visit to teledermatology, 294 (29.5%) patients were keen, 166 (16.6%) were unsure and 537 (53.9%) declined. Significant factors for declining teledermatology were lack of prior exposure to videoconferencing ( P < 0.01) and lower educational level ( P = 0.019). Patients also raised concerns regarding the ability of teledermatology to address medical concerns (32.1%) and indicated a preference for face-to-face consultation (29.7%).
CONCLUSION
Factors that influence patients' decision to adopt teledermatology, such as concerns about its ability to address medical issues, lack of IT literacy or experience in teleconferencing, are modifiable. Targeted strategies such as careful patient selection, a dedicated teleconsultation workflow, and the use of a novel 'teledermatology patient journey' (including a clinic walkthrough at the first visit) and an intuitive audio-enabled user interface, may improve patient perceptions and adoption of teleconsultation service.

7.Case of stiff skin syndrome treated with acupuncture and cupping therapy.
Chinese Acupuncture & Moxibustion 2025;45(7):982-984
Stiff skin syndrome is a very rare non-inflammatory reactive skin disease, characterized by skin sclerosis and limited joint mobility. The paper reports one case of child with stiff skin syndrome and treated with combined therapy of acupuncture and cupping. Acupuncture was used at the lateral line 1 of vertex (MS8) on the right side, Jiaji (EX-B2) of L2 to L4, Huantiao (GB30), ashi point, Juliao (GB29), Fengshi (GB31), Weizhong (BL40), and etc. on the left side. After deqi, the electrodes of KWD-808Ⅰimpulse electronic therapeutic device were attached to Jiaji (EX-B2) of L4 and Huantiao (GB30), Fengshi (GB31) and Yanglingquan (GB34) on the left side respectively, at disperse-dense wave, a frequency of 2 Hz/100 Hz, and a current of 2 mA. The needles were retained for 20 min. Acupuncture was operated once every 2 days, 3 interventions a week. When acupuncture was completed in each intervention, moving cupping was followed till the skin turned to be red, along the distribution of the governor vessel, foot-shaoyang gallbladder meridian and foot-taiyang bladder meridian on the left side, of the lumbar region and leg. Moving cupping was delivered once every 2 days, 3 times a week. Once a week, after moving cupping, the cups were retained on the areas with skin stiffness for 8 min to 10 min. One course of the combined therapy of acupuncture and cupping was composed of 6 treatments. After 2 courses of treatment, the skin stiffness on the left buttock region and the lateral side of the lower limb was ameliorated, the swelling on the left lower limb relieved and the walking improved; and the patient could walk continuously for 2 000 m. The combined therapy of acupuncture and cupping provides a new idea for the clinical treatment of stiff skin syndrome.

The paper reports one case of primary cutaneous amyloidosis (PCA) treated by tapping with plum-blossom needle combined with sulfur ointment and local irradiation. PCA in this case was manifested as generalized erythema, papules, plaques, lichenification, and severe pruritus. In treatment, tapping with plum-blossom needle was delivered at typical lesions to induce local congestion, redness, and minimal bleeding. After cleaned with sterile gauze for 10 s, 25% sulfur ointment was evenly applied, followed by local irradiation with a TDP lamp for 15 min. This session was repeated twice a week. In 1 month of treatment, the lesions turned flat and the skin was soft as the normal, with pigmentation and mild pruritus left. In 3 months of follow-up, no papules recurred, and mild pruritus presented occasionally.

OBJECTIVES:
To explore the mechanism by which Pulsatilla saponin D (PSD) inhibits invasion and metastasis of triple-negative breast cancer (TNBC).
METHODS:
The public databases were used to identify the potential targets of PSD and the invasion and metastasis targets of TNBC to obtain the intersection targets between PSD and TNBC. The "PSD-target-disease" interaction network was constructed and protein-protein interaction (PPI) analysis was performed to obtain the core targets, which were analyzed for KEGG pathway and GO functional enrichment. Molecular docking study of the core targets and PSD was performed, and the therapeutic effect and mechanism of PSD were verified using Transwell assay and Western blotting in cultured TNBC cells.
RESULTS:
Network pharmacology analysis identified a total of 285 potential PSD targets and 26 drug-disease intersection core targets. GO analysis yielded 175 entries related to the binding of biomolecules (protein, DNA and RNA), enzyme activities, and regulation of gene transcription. KEGG analysis yielded 46 entries involving pathways in cancer, chemical carcinogenesis-receptor activation, microRNAs in cancer, chemical carcinogenesis-reactive oxygen species, PD-L1 expression and PD-1 checkpoint pathway in cancer. Molecular docking showed high binding affinities of PSD to MTOR, HDAC2, ABL1, CDK1, TLR4, TERT, PIK3R1, NFE2L2 and PTPN1. In cultured TNBC cells, treatment with PSD significantly inhibited cell invasion and migration and lowered the expressions of MMP2, MMP9, N-cadherin and the core proteins p-mTOR, ABL1, TERT, PTPN1, HDAC2, PIK3R1, CDK1, TLR4 as well as NFE2L2 expressionin the cell nuclei.
CONCLUSIONS
The inhibitory effects of PSD on TNBC invasion and metastasis are mediated by multiple targets and pathways.

OBJECTIVES:
To investigate the effects of dihydroartemisinin (DHA) combined with doxorubicin (DOX) on proliferation and apoptosis of triple-negative breast cancer cells and explore the underlying molecular mechanism.
METHODS:
MDA-MB-231 cells were treated with 50, 100 or 150 μmol/L DHA, 0.5 μmol/L DOX, or with 50 μmol/L DHA combined with 0.5 μmol/L DOX. The changes in proliferation and survival of the treated cells were examined with MTT assay and colony-forming assay, and cell apoptosis was analyzed with flow cytometry. Western blotting was performed to detect the changes in protein expression levels of PCNA, cleaved PARP, Bcl-2, Bax, STAT3, p-STAT3, HIF-1α and survivin.
RESULTS:
The IC50 of DHA was 131.37±29.87 μmol/L in MDA-MB-231 cells. The cells with the combined treatment with DHA and DOX showed significant suppression of cell proliferation. Treatment with DHA alone induced apoptosis of MDA-MB-231 cells in a dose-dependent manner, but the combined treatment produced a much stronger apoptosis-inducing effect than both DHA and DOX alone. DHA at 150 μmol/L significantly inhibited clone formation of MDA-MB-231 cells, markedly reduced cellular expression levels of PCNA, p-STAT3, HIF-1α and survivin proteins, and obviously increased the expression level of cleaved PARP protein and the Bax/Bcl-2 ratio, and the combined treatment further reduced the expression level of p-STAT3 protein and increased the Bax/Bcl-2 ratio.
CONCLUSIONS
DHA combined with DOX produces significantly enhanced effects for inhibiting cell proliferation and inducing apoptosis in MDA-MB-231 cells possibly as result of DHA-mediated negative regulation of the STAT3/HIF-1α pathway.
