Introduction:
Histoplasmosis is a disease of global distribution with diverse manifestations caused by the dimorphic fungus Histoplasma capsulatum. It is frequently described in severely immunocompromised and Human Immunodeficiency Virus (HIV)-positive
individuals. Despite being widely reported in Southeast Asia, few cases have been reported in the Philippines.
Case Report:
A 53-year-old Filipino male who presented with umbilicated papules resembling molluscum contagiosum, and a previous
history of a left lung mass with initial complaints of cough and hemoptysis. Gram stain of his sputum revealed the presence of fungal
elements, otherwise not specified. In relation to this, a fine-needle aspiration biopsy of the suspected lung mass was done. However,
findings were negative for malignant cells and fungi.
Dermoscopy revealed central ulceration and necrosis with faint peripheral arborizing telangiectasia and surrounding superficial scaling.
Histopathologic analysis revealed a diffuse granulomatous dermatitis, and Periodic acid-Schiff (PAS) and Grocott methenamine silver
(GMS) stains showed numerous small yeast-like structures measuring approximately 3.74µm in diameter. Tissue culture of the skin lesion
on the right thigh isolated fungal elements but was not specified. As histoplasmosis is an AIDS-defining infection and often found in immunocompromised states, screening for HIV was done which revealed negative results. Interestingly, disease distribution of histoplasmosis in the Philippines was frequently found in HIV-negative patients. Due to persistent serum creatinine elevation of over 300 µmol/L,
renal biopsy was also done and revealed similar fungal elements. With these findings, a diagnosis of disseminated histoplasmosis was
made. After a month of treatment with oral itraconazole, there was marked improvement of the patient’s skin lesions.
Conclusion
This case highlights the importance of recognizing cutaneous manifestations and maintaining a high index of suspicion for
histoplasmosis in HIV-seronegative patients.

Histoplasmosis is well-characterized as a fungal
disease that more commonly occurs in North America,
mostly endemic in Ohio and Mississippi river valleys.
The clinical spectrum of histoplasmosis ranges from
asymptomatic infection to a fatal disease. Progressive
disseminated histoplasmosis is typically seen in
immunocompromised individuals and presents with
non-specific systemic symptoms associated with
cutaneous manifestations of papules and nodules.? We
report a case of a 28-year old Filipino female with a
history of exposure to soil activities months before
consult. The patient presented with a 3-week history of
erythematous macules, vesicles, and pustules over the
face, arms, and trunk, which evolve into papules and
plaques with hemorrhagic crusting. Patient was initially
diagnosed and treated as a case of varicella but had no
improvement with initial management. Histopathologic
findings were consistent with histoplasmosis. The
patient was started with oral itraconazole, but
unexpectedly expired before any improvement in
cutaneous symptoms were noted.

OBJECTIVE:
To observe the clinical effect of bloodletting at auricular dorsal vein combined with auricular point sticking on menstrual migraine (MM) of qi stagnation and blood stasis, and explore its possible mechanism.
METHODS:
A total of 102 cases of MM with qi stagnation and blood stasis were randomly divided into an observation group (51 cases, 3 cases dropped off) and a control group (51 cases, 2 cases dropped off). The patients in the observation group were treated with bloodletting at auricular dorsal vein combined with auricular point sticking. The bloodletting was performed at vein at upper 1/3 of the dorsalis near the ear helix; the auricular point sticking was performed at Pizhixia (AT4), Neifenmi (CO18), Jiaogan (AH6a), Nie (AT2), Zhen (AT3), Shenmen (TF4) and Yidan (CO11). The auricular points of both ears were alternate used. From 7 days before the onset of menstruation, bloodletting at auricular dorsal vein was given once every 7 days, 3 times were taken as a course of treatment, and 1 course of treatment was given; the auricular point sticking was given once every 3 days, and 6 times of treatment were given. The patients in the control group were treated with oral administration of flunarizine hydrochloride capsules. From 7 days before the onset of menstruation, flunarizine hydrochloride was given 2 capsules per time, once a day for 3 weeks. The menstrual headache index and visual analogue scale (VAS) score of the two groups were observed before treatment, one menstrual cycle into treatment and the first and the second menstrual cycle after treatment; the migraine-specific quality of life questionnaire (MSQ) score and the serum levels of estradiol (E2) and 5-hydroxytryptamine (5-HT) were compared before treatment and one menstrual cycle into treatment; the clinical efficacy was evaluated at one menstrual cycle into treatment.
RESULTS:
Compared before treatment, the menstrual headache index and VAS scores were reduced at one menstrual cycle into treatment and the first and second menstrual cycle after treatment in the two groups (P<0.05), and those in the observation group were lower than the control group (P<0.05). Compared before treatment, the MSQ scores and the serum levels of E2 and 5-HT in the two groups were increased at one menstrual cycle into treatment (P<0.05), and those in the observation group were higher than the control group (P<0.05). The total effective rate was 95.8% (46/48) in the observation group, which was higher than 73.5% (36/49) in the control group (P<0.05).
CONCLUSION
Bloodletting at auricular dorsal vein combined with auricular point sticking could relieve headache intensity, improve the quality of life in patients with MM of qi stagnation and blood stasis, which may be achieved by raising the serum levels of E2 and 5-HT to improve the level of hormone in the body.

Objective: To explore the epidemiological characteristics of sample distribution and antifungal susceptibilities of clinically invasive C. tropicalis isolates from 2017 to 2021 in East China. Methods: Using a retrospective analysis, the East China Invasive Fungal Infection Group (ECIFIG) collected C. tropicalis clinically isolated from 32 hospitals in East China between January 2017 and December 2021. The identification results of the strains were reviewed using mass spectrometry by the central laboratory of the Shanghai East Hospital. The minimum inhibitory concentrations (MICs) of the strains against fluconazole (FLU), voriconazole (VOR), itraconazole (ITR), Posaconazole (POS), isavuconazole (ISA), anidulafungin (ANI), caspofungin (CAS), micafungin (MICA) and 5-fluorocytosine (FCT) were tested by the ThermoFisher CMC1JHY colorimetric microdilution method. The MIC of amphotericin B (AMB) was tested by the broth microdilution method. The MIC results were analyzed based on the clinical breakpoints and epidemiological cutoff values (ECV) published by the Clinical and Laboratory Standards Institute (CLSI) M27 Ed3 and M57 Ed4 documents. Data analysis was conducted using the Kruskal-Wallis test and paired t-test. Results: In total, 305 C. tropicalis isolates were collected. There were 38.0% (116/305) strains isolated from blood, 11.5% (35/305) ascites, 8.9% (27/305) catheter and 8.9% (27/305) drainage fluid. The resistance rate of C. tropicalis to FLU was 32.5%, to VOR was 28.5%, and the cross-resistance rate to FLU and VOR was 28.5%. The wild-type proportions for ITR and POS were 79.3% and 29.2% respectively. There was no significant difference in resistance rates, MIC50, and MIC90 of FLU and VOR, or in the wild-type rates of ITR and POS over five years. More than 95.0% of the isolates were susceptible to echinocandins. However, one strain was identified as being multi-drug resistant. In azole antifungals, voriconazole, itraconazole, posaconazole, and isavuconazole have similar GM MIC values. The GM MIC of fluconazole is significantly higher than that of itraconazole (t=9.95, P<0.05), posaconazole (t=9.99, P<0.05), and voriconazole (t=10.01, P<0.05), Meanwhile, among echinocandins, the GM MIC of ANI was comparable to that of CAS (t=1.17, P>0.05), both of which were significantly higher than MICA (t=11.56, P<0.05; t=4.15, P<0.05). Conclusion: The clinical isolates of C. tropicalis in East China from 2017 to 2021 were relatively susceptible to echinocandins. However, there was consistently high resistance to fluconazole and voriconazole. More intensive efforts should be made on the monitoring of drug resistance in C. tropicalis.

OBJECTIVE:
To compare the clinical effect of electroacupuncture at Siguan points and flunarizine hydrochloride capsule on migraine of liver yang hyperactivity.
METHODS:
A total of 110 patients with migraine of liver yang hyperactivity were randomly divided into an electroacupuncture group (55 cases, 2 cases dropped off) and a western medication group (55 cases, 2 cases dropped off). In the electroacupuncture group, electroacupuncture was applied at Siguan points (Hegu [LI 4] and Taichong [LR 3]), with disperse-dense wave of 2 Hz/100 Hz in frequency and current intensity of 0.1-1 mA, 30 min each time, once a day, 5 times per week for 4 weeks. Flunarizine hydrochloride capsule was given orally in the western medication group, 10 mg a day for 4 weeks. The visual analogue scale (VAS) score and the migraine attack days were observed before and after treatment, during follow-up of 1, 3 and 6 months, and the migraine symptom score was observed before and after treatment in the two groups.
RESULTS:
After treatment, during follow-up of 1, 3 and 6 months, the VAS scores and the migraine attack days in the two groups were decreased compared with before treatment (P<0.05), and above indexes in the electroacupuncture group were lower than the western medication group (P<0.05). After treatment, the migraine symptom scores in the two groups were decreased (P<0.05), the change in the electroacupuncture group was greater than the western medication group (P<0.05).
CONCLUSION
Electroacupuncture at Siguan points could effectively reduce headache intensity and migraine attack days, relieve migraine symptoms in patients with migraine of liver yang hyperactivity, and the efficacy is superior to oral flunarizine hydrochloride capsules.

Objective: To investigate the clinical manifestations, treatments, and prognosis of pediatric patients with Talaromyces marneffei infection. Methods: In this retrospective study, 7 children diagnosed with Talaromyces marneffei infection in Shenzhen Children's Hospital from July 2017 to October 2021 were recruited. The clinical features, radiology, pathogen detection, immunological evaluation, treatments, and prognosis were analyzed. Results: In 7 cases, 5 were male, 2 were females. The age was from 0.75 to 8.75 years. The main clinical manifestations were fever in 7 cases, cough in 6 cases, malnutrition in 4 cases, papules in 2 cases and medical history of recurrent infection in 3 cases. Physical examination showed that all 7 patients had hepatosplenomegaly, 4 had superficial lymphadenopathy. Laboratory examination showed that 6 cases had decreased hemoglobin and 3 cases had decreased platelet. Chest CT showed that 4 cases had patchy shadows, pleural effusion, mediastinal or axillary lymph node enlargement, 3 had nodular shadows and 2 had cavities. The positive ratio of Talaromyces marneffei culture was 2/2 with tissue samples, 4/5 with bone marrow. The positive ratio was 3/4 by metagenomic next generation sequencing. The fungus was detected in 3 cases by smear microscopy of bone marrow and (or) peripheral blood. All patients were negative for human immunodeficiency virus by the immune function assay. However, 5 cases were confirmed as primary immunodeficiency disease, including 2 cases with high IgM syndrome, 2 with STAT1 gene variation, and the last with severe combined immunodeficiency (IL2RG gene variation). Exclude 1 case which gave up treatment due to acute intracranial infection, and the other patients received effective treatments along with amphotericin B, voriconazole, and itraconazole alone or in combination. Two cases relapsed after medication withdrawal, but 1 case got complete rehabilitation after hematopoietic stem cell transplantation. Conclusions: The clinical manifestations involve multisystem, the common charateristics are fever and cough. The chest CT imaging manifestations are diverse, it should be considered in differentiating tuberculosis. The amphotericin B, voriconazole and itraconazole are effective, but it will easily relapse when withdrawing those antifungal agents.

9.Expert consensus on ensartinib in the treatment of anaplastic lymphoma kinase-positive non-small cell lung cancer.
Chinese Journal of Oncology 2022;44(4):297-307
The mutation rate of anaplastic lymphoma kinase (ALK) in patients with non-small cell lung cancer is 3% to 7%. Due to its low mutation rate and better long-term survival compared with epidermal growth factor receptor-positive non-small cell lung cancer patients, therefore, it's called "diamond mutation". At present, there are three generations of ALK tyrosine kinase inhibitor (TKI) drugs in the world. The first-generation ALK-TKI drug approved in China is crizotinib, and the second-generation drugs are alectinib, ceritinib and ensartinib. Among them, ensartinib is an ALK-TKI domestically developed, and its efficacy is similar to that of alectinib. The main adverse event is transient rash, and compliance to ensartinib is better from the perspective of long-term survival of patients. The manifestation of rash caused by ensartinib is different from that of other ALK-TKI drugs. In order to facilitate clinical application and provide patients with more treatment options, under the guidance of the Committee of Cancer Rehabilitation and Palliative Care of China Anti-Cancer Association, this article collects and summarizes the common adverse reactions of ensartinib. Based on the clinical practice, a clear adverse classification and specific treatment plan are formulated, in order to provide a corresponding reference for clinicians to make more comprehensive clinical decisions.

Abivertinib, a third-generation tyrosine kinase inhibitor, is originally designed to target epidermal growth factor receptor (EGFR)-activating mutations. Previous studies have shown that abivertinib has promising antitumor activity and a well-tolerated safety profile in patients with non-small-cell lung cancer. However, abivertinib also exhibited high inhibitory activity against Bruton's tyrosine kinase and Janus kinase 3. Given that these kinases play some roles in the progression of megakaryopoiesis, we speculate that abivertinib can affect megakaryocyte (MK) differentiation and platelet biogenesis. We treated cord blood CD34+ hematopoietic stem cells, Meg-01 cells, and C57BL/6 mice with abivertinib and observed megakaryopoiesis to determine the biological effect of abivertinib on MK differentiation and platelet biogenesis. Our in vitro results showed that abivertinib impaired the CFU-MK formation, proliferation of CD34+ HSC-derived MK progenitor cells, and differentiation and functions of MKs and inhibited Meg-01-derived MK differentiation. These results suggested that megakaryopoiesis was inhibited by abivertinib. We also demonstrated in vivo that abivertinib decreased the number of MKs in bone marrow and platelet counts in mice, which suggested that thrombopoiesis was also inhibited. Thus, these preclinical data collectively suggested that abivertinib could inhibit MK differentiation and platelet biogenesis and might be an agent for thrombocythemia.
