RESUMEN
OBJECTIVES: This study assessed the real-world relative vaccine effectiveness of the ChAdOx1/AZD1222 vaccine given intradermally at one-fifth dose compared to the standard intramuscular injection, following the completion of two doses of CoronaVac, due to limited vaccine availability in Thailand during the Coronavirus disease 2019 (COVID-19) pandemic. METHOD: This retrospective cohort study used 138,264 records from Vachira Phuket Hospital, Phuket, Thailand. The records were divided into two groups: 49,387 recipients received one-fifth doses via intradermal injections, and 88,877 recipients received standard-dose intramuscular injections from September 14 to October 3, 2021, with follow-up until December 31, 2021. Relative vaccine effectiveness for the cohorts was estimated using Cox regression, adjusting for demographic and clinical risk factors. RESULTS: The adjusted hazard ratio between the intradermal and intramuscular groups was 0.88 (95% Confidence Interval 0.76-1.02, pâ¯=â¯0.09), indicating a non-significant protective factor for the intradermal group. Further stratified analysis revealed no significant difference between the two groups. The 21 and 28-day post-vaccination periods minimized the possibility of confounding due to differences in the cohorts' timeframes. CONCLUSION: A booster dose of ChAdOx1/AZD1222 given intradermally at one-fifth dose did not show a significant difference compared to the standard intramuscular injection.
RESUMEN
Lymphoscintigraphy is a nuclear medicine procedure that uses a small quantity of radioactive particles for visualizing the lymphatic system. Traditionally, the radiotracer was injected subcutaneously, but the quality of lymphatic path imaging was scarce due to high background. Intradermal radiotracer injection is considered the modern-day intralymphatic injection. We propose rest/stress intradermal lymphoscintigraphy for the diagnosis, staging and surgical planning of lymphedema. Major and minor findings were described in primary and secondary lymphedema. Based on the in-depth information of the lymphatic pathways, physiotherapists and microsurgeons can obtain important functional information in patients' selection to treat with physical treatments and/or undergo microsurgery.
RESUMEN
BACKGROUND: The skin-prick and intradermal tests are the main diagnostic methods used to identify the causative agent in patients with suspected perioperative anaphylaxis. Although the intradermal test is more sensitive than the skin-prick test, multiple intradermal injections can be painful for children. Here, we present the case of a child with autism and suspected perioperative anaphylaxis. The causative agent was successfully identified using the intradermal test under general anesthesia. CASE PRESENTATION: An 8-year-old boy with autism developed anaphylaxis during general anesthesia for the fourth cleft lip and palate surgery. An allergic workout was performed, but both the skin-prick and basophil activation tests for suspected causative agents yielded negative results. The patient was afraid of multiple injections, and an intradermal test was performed under general anesthesia by anesthesiologists and allergists. Piperacillin was confirmed as the causative agent, and subsequent surgery using the same anesthetic agents without piperacillin was uneventful. CONCLUSIONS: Concerted efforts should be made to identify the causative agent for diagnosing perioperative anaphylaxis.
RESUMEN
BACKGROUND: Maximal skin testing (ST) nonirritant concentrations (NICs) are consistent for penicillin and aminopenicillin among guidelines. However, there is variability among guidelines for maximal ST NICs of cephalosporins. OBJECTIVE: To determine maximal immediate and delayed ST NICs of 15 ß-lactams in ß-lactam-tolerant and ß-lactam-naïve participants. METHODS: We performed a single-center, nonrandomized prospective study between September 2019 and January 2022 in adult participants. Participants received skin prick testing (SPT) and intradermal test (IDT) injections at 6 increasing concentrations of 1 or more ß-lactams. A concentration was considered irritant when more than 5% of participants had a positive test. A positive test was defined as a wheal ≥3 mm compared with negative control accompanied by a ≥5 mm flare for SPT/IDT and induration ≥5 mm with associated erythema at 48 hours for delayed readings (dIDT). Sensitivity analyses using 3 alternative IDT positive criteria were conducted. RESULTS: A total of 747 participants with a median age of 64 (interquartile range: 54-72) years (52% male, 85% White, and 92% non-Hispanic) underwent 20,858 skin tests. All undiluted SPT concentrations were nonirritant. We found the following maximal IDT/dIDT NICs (mg/mL): ampicillin (41.6/125), ampicillin-sulbactam (93.8/187.5), aztreonam (6.3/25), cefazolin (55/165), cefepime (35/140), cefoxitin (45/90), ceftaroline (7.5/15), ceftriaxone (58.3/175), cefuroxime (55/110), ertapenem (16.6/50), imipenem-cilastin (6.3/25), meropenem (8.3/25), nafcillin (31.3/62.5), oxacillin (20.9/83.5), and piperacillin-tazobactam (112.5/225). dIDTs were almost all completely nonirritant close to or at undiluted concentrations. There were no differences when we applied 3 IDT positivity criteria to our raw data. CONCLUSIONS: Our results suggest that SPTs with undiluted stock ß-lactam antibiotic concentrations are nonirritant. Compared with previously published nonirritant concentrations, we propose a 2- to 50-fold increase to the maximal IDT and dIDT NICs of 15 ß-lactam antibiotics. When performing dIDTs, a higher concentration should be used rather than the same IDT concentration.
RESUMEN
The water buffalo (Bubalus bubalis) is susceptible to bovine tuberculosis (TB), which receives increased attention in areas where buffalo breeding is prevalent, such as in Southern Italy, especially in the Campania region, where 70% of the buffalo stock is bred. Since 2012, TB testing in buffalo herds has been conducted using the Single Intradermal Test (SIT), with the Comparative Intradermal test (CIT) used in cases of inconclusive results. From 2012 to 2016, the interferon-gamma (IFN-γ) test was occasionally employed experimentally in herds with TB outbreaks to expedite eradication efforts. A local TB eradication program was implemented in officially TB-free buffalo herds between 2017 and 2019. This program involves initial screening with SIT, followed by confirmatory tests, including CIT and IFN-γ, for positive reactions. Since June 2019, the IFN-γ test has replaced the CIT in officially TB-free herds upon positive SIT reactions. Additionally, in suspected and confirmed TB-outbreak herds, the IFN-γ test was used at the discretion of the competent authority. Between 2017 and 2019, approximately 295,000 buffaloes in Campania were screened annually with in vivo tests provided by TB eradication programs. During this period, 32,040 animals from 855 herds were tested using the IFN-γ test and 4,895 tested positive. Since 2020, the use of IFN-γ testing has increased, and has become a prerequisite for the acquisition of TB-free status and is being systematically applied for TB outbreak-extinction procedures. The test was performed in all breeding buffaloes in cases of doubtful SIT results in TB-free herds and when TB lesions are detected at slaughter in animals from TB-free herds. This combined approach helped detect more TB outbreaks, and thereby led to a reduction in the TB prevalence and incidence rates. By 2022, the prevalence had decreased to 1.56%, and the incidence had decreased to 0.73%, after the increased use of the IFN-γ test. This study highlights the effectiveness of implemented strategies in reducing TB in this region. Overall, the data demonstrate the successful impact of TB eradication measures and surveillance activities in reducing bubaline TB prevalence and incidence in the Campania region.
RESUMEN
BACKGROUND: Atypical intradermal smooth muscle neoplasm, also commonly termed cutaneous leiomyosarcoma, is a soft tissue tumor with a low risk of aggressive behavior. These lesions arise in the dermis with possible superficial subcutaneous extension, demonstrate cytologic atypia, and often show mitotic activity. METHODS: A retrospective review of patient demographics, tumor characteristics, and treatment methods was conducted in a consecutive series of patients presenting to MD Anderson Cancer Center (MDACC) from 2002 to 2021 (n = 95). All pathology was reviewed by MDACC pathologists and determined to be atypical intradermal smooth muscle neoplasm. RESULTS: Median age at diagnosis was 58 years (range 22-86), and 74% were male. Ninety-five percent (n = 90) of patients identified as White, non-Hispanic. Most tumors were slow-growing, solitary, and painless nodules. Tumors were in the lower extremities (44.2%), followed by the upper extremity (28.4%), trunk (22.1%), and head and neck (5.2%). All patients (n = 44, 46.3%) who had a punch/incisional biopsy for diagnostic purposes had a subsequent tumor excision. Unplanned excision or excisional biopsy was performed on the remaining 46 (48%) patients. Of this subset, 41 of the 46 aforementioned patients (89%) had positive margins and underwent re-excision. Final pathology in 25/38 (66%) re-excision specimens was negative for residual tumor despite an initial positive margin. Two patients in the cohort had local recurrence 2 and 3 years after initial surgery. Both patients had positive margins, underwent excision of the recurrent tumor, and remain free of disease. After median follow-up of 6.9 years (range 1 day-18 years), 5-year recurrence-free survival was 96% and overall survival (OS) of the entire cohort was 78%. CONCLUSION: In this study of consecutive patients presenting with atypical intradermal smooth muscle neoplasm, we found good OS and local control after definitive surgical excision with negative margins, including excisional biopsy with close margins. Atypical intradermal smooth muscle neoplasm is unlikely to metastasize and has an excellent prognosis. Guidelines to determine optimal surveillance strategies for these patients should be revisited.
RESUMEN
Background and Purpose: Skin pores (SPs) are normal and benign skin structures that are mostly located on the face (nose, cheeks, etc.) that cause many aesthetic concerns or complaints. One known effective treatment is botulinum toxin A (BTXA), which is also approved for the treatment of strabismus, blepharospasm, muscle spasm, cervical dystonia, glabella wrinkles, and primary axillary hyperhidrosis. Therefore, the aim of this study was to compare the effect of intra-dermal injection of botulinum toxin and normal saline serum (NSS) in the treatment of large facial pores. Methods: The study included 25 people who referred to the skin clinic of Imam Khomeini Hospital in Ahvaz from June 2021 to January 2022 for the treatment of large facial skin pores. Randomly, some subjects were injected with botulinum toxin at ten points, and each point was equivalent to 2.5 units of Masport (500 units vial of Masport diluted with 10 ml of NSS). Some other people were injected with 0.05 ml of NSS by intra-dermal injection at ten points. Finally, the data were analyzed using SPSS-Ver. 22 software. Results: Based on optical coherence tomography results, it was determined that the diameter of facial pores decreased significantly (P = 0.011). Dermoscopy showed a significant decrease in the average size of facial pores (P < 0.011), and also, the pore score decreased significantly (P = 0.021). In addition, the results showed that the size of skin pores and facial fat on both sides of the face did not decrease significantly from the patients' point of view (P = 0.71). Conclusion: Based on the results of the present study, it can be concluded that intra-dermal injection of botulinum toxin is an effective and safe method to control facial pores, which showed acceptable results after 3 months.
RESUMEN
BACKGROUND: Topical therapy is preferred for otitis externa (OE) in dogs. Otic products commonly contain glucocorticoids that can be systemically absorbed and possibly interfere with diagnostic tests such as intradermal testing (IDT). HYPOTHESIS/OBJECTIVES: To determine the effect of a long-lasting otic solution containing mometasone furoate (MF) on IDT immediate reactions and to determine withdrawal time before IDT. ANIMALS: Seventeen dogs with healthy ears (Group 1) and 12 with OE (Group 2). MATERIALS AND METHODS: Intradermal injections of histamine, anticanine-immunoglobulin (Ig)E and saline were subjectively and objectively evaluated before treatment and weekly for 6 weeks, after a single application of a long-lasting otic solution containing MF. RESULTS: Statistically significant reductions in the mean subjective histamine scores after application of MF were observed at Weeks 1 (p = 0.012) and 2 (p = 0.028) in Group 1, and Weeks 1 (p = 0.00066), 2 (p = 0.02) and 4 (p = 0.034) in Group 2. Mean histamine objective scores were significantly reduced in Weeks 1 (p = 0.042), 2 (p = 0.0009), 3 (p = 0.001) and 5 (p = 0.018) in Group 1 only. The mean subjective anticanine-IgE scores were significantly reduced in Week 1 in both groups (p = 0.003, p = 0.0066), respectively. There were no significant changes in the mean anticanine-IgE objective score in either group. CONCLUSIONS AND CLINICAL RELEVANCE: Application of a long-lasting otic solution containing MF can interfere with IDT immediate reactions in healthy and OE dogs. Based on the subjective evaluation, IDT can be performed ≥2 weeks after application of the otic solution in healthy dogs, and ≥4 weeks in dogs with OE.
RESUMEN
Cutaneous adverse drug reactions collectively are delayed drug reactions such as morbilliform drug eruption and severe cutaneous adverse reactions (SCARs). Morbilliform drug eruption may wane over time, be the result of drug viral interactions, and be amenable to slow reintroduction or rechallenge, whereas SCARs are HLA class I restricted, T-cell-mediated reactions that demonstrate durable immunity and warrant lifelong avoidance. SCARs such as drug reaction with eosinophilia and systemic symptoms, Stevens-Johnson syndrome and toxic epidermal necrolysis, acute generalized exanthematous pustulosis, and generalized bullous fixed drug eruption often occur in the setting of multiple drugs dosed together. Collectively, they lead to significant morbidity, mortality, and drug safety concerns that could severely limit future treatment options. Currently, no single or combination of diagnostic tests for SCARs such as ex vivo or in vitro testing, in vivo (skin) testing, or other adjunctive tests such as HLA typing have 100% negative predictive value. In this "Controversies in Allergy Review" article, we review the current literature on delayed skin testing (patch and delayed prick/intradermal test) and critically assess the evidence base of its utility across different drugs and clinical phenotypes of delayed hypersensitivity reactions.
RESUMEN
Background and Objectives: The facial skin defects associated with aging are common concerns in the aging population. Hyaluronic-acid-based intradermal gels have established themselves as safe and effective treatments for addressing these concerns. Recently developed enriched products aim to enhance the efficacy of these gels, yet their effectiveness lacks thorough validation in the existing literature. Materials and Methods: In this retrospective analysis, we investigated the outcomes of intradermal gel treatments in 103 patients with soft tissue defects. This study included three groups: 35 patients received amino-acid-enriched hyaluronic acid gel, another 35 were treated with hydroxyapatite-enriched hyaluronic acid gel, and the remaining 33 underwent hyaluronic acid treatment only. The efficacy of the treatments was assessed using the Global Aesthetic Improvement Scale (GAIS) score, while patient satisfaction was gauged through a detailed questionnaire. Any adverse event was monitored. Results: The treatments demonstrated remarkable efficacy, as evidenced by mean GAIS scores of 1.714 points for those treated with amino acid-enriched hyaluronic acid gel, 1.886 points for individuals receiving hydroxyapatite-enriched hyaluronic acid gel, and 1.697 for those treated with hyaluronic acid alone, all showing statistical significance (p < 0.0001). Patient satisfaction was very high. Significantly, there were no recorded instances of major adverse events. Conclusions: Hyaluronic gels, particularly those enriched with amino acids and hydroxyapatite, are effective and safe interventions for addressing facial skin aging defects. They serve as valuable tools in mitigating age-related blemishes and contribute to the overall improvement of skin aesthetics.

OBJECTIVE: To analyze the effects of Shugan Tiaoshen (regulating liver and harmonizing spirit) intradermal needling protocol on the attentional networks of patients with subthreshold depression using the attention network test (ANT). METHODS: Eighty patients with subthreshold depression were randomly divided into an intradermal needling group (40 cases) and a sham needling group (40 cases, 2 cases dropped out), with an additional 43 healthy subjects as a normal group. The intradermal needling group received intradermal needling treatment, while the sham needling group received sham intradermal needling, with the needle tip not penetrating the skin. The bilateral Xinshu (BL 15), Ganshu (BL 18), Shentang (BL 44) as well as auricular points Xin (CO15) and Gan (CO12) were selected alternately. Treatments were administered twice a week for a total of 6 weeks in the two groups. The patient health questionnaire-9 (PHQ-9) and generalized anxiety disorder (GAD-7) scores were observed before treatment, after 3 weeks of treatment, after treatment, and at 1 month after the end of treatment (follow-up), and the ANT of the two groups of patients with subthreshold depression before and after treatment as well as the normal group of healthy subjects was compared. RESULTS: The PHQ-9 and GAD-7 scores of the patients with subthreshold depression were decreased after 3 weeks of treatment, after treatment, and in follow-up in the two groups (P<0.05), the differences in PHQ-9 and GAD-7 scores before and after treatment were greater in the intradermal needling group than those in the sham needling group (P<0.01). Before treatment, the executive control network reaction time of the subthreshold depression group (the intradermal needling group and the sham needling group) was higher than that of the normal group (P<0.05). Compared before treatment, the executive control network reaction time of the patients in the intradermal needling group and the sham needling group was decreased after treatment (P<0.05), and the alerting network reaction time of the intradermal needling group was increased after treatment (P<0.05); the difference in alerting network reaction time before and after treatment was greater in the intradermal needling group than that of the sham needling group (P<0.01). CONCLUSION: Regulating liver and harmonizing spirit intradermal needling protocol could effectively improve depressive and anxious symptoms in patients with subthreshold depression, and enhance the efficiency of the alerting network.

Vaccines play a critical role in combating infectious diseases and cancers, yet improving their efficacy remains challenging. Here, we introduce a separable nanocomposite hydrogel microneedle (NHMN) patch designed for intradermal and sustained delivery of ovalbumin (OVA), a model antigen, to enhance adaptive immune responses. The NHMN patch consists of an array of OVA-loaded microneedles made from photo-cross-linked methacrylated hyaluronic acid and laponite (LAP), supported by a hyaluronic acid backing. The incorporation of LAP not only enhances the mechanical strength of the pure hydrogel microneedles but also significantly prolongs OVA release. Furthermore, in vitro cell experiments demonstrate that NHMNs effectively activate dendritic cells without compromising cell viability. Upon skin penetration, NHMNs detach from the backing as the hyaluronic acid rapidly dissolves upon contact with the skin interstitial fluid, thereby acting as antigen reservoirs to release antigens to abundant skin dendritic cells. NHMNs containing 0.5% w/v LAP achieved a 15-day OVA release in vivo. Immunization studies demonstrate that the intradermal and sustained release of OVA via NHMNs elicited stronger and longer-lasting adaptive immune responses compared to conventional bolus injection. Given its easy to use, painless and minimally invasive features, the NHMN patch shows promise in improving vaccination accessibility and efficacy against a range of diseases. STATEMENT OF SIGNIFICANCE: The study introduces a separable nanocomposite hydrogel microneedle (NHMN) patch. This patch consists of an array of ovalbumin (OVA, a model antigen)-loaded microneedles made from photo-cross-linked methacrylated hyaluronic acid and laponite, with a hyaluronic acid backing, designed for intradermal and sustained delivery of antigens. This patch addresses several key challenges in traditional vaccination methods, including poor antigen uptake and presentation, and rapid systematic clearance. The incorporation of laponite enhances mechanical strength of microneedles, promotes dendritic cell activation, and significantly slows down antigen release. NHMN-based vaccination elicits stronger and longer-lasting adaptive immune responses compared to conventional bolus injection. This NHMN patch holds great potential for improving the efficacy, accessibility, and patient comfort of vaccinations against a range of diseases.
RESUMEN
Microarray patches (MAPs) offer a noninvasive and patient-friendly drug delivery method, suitable for self-administration, which is especially promising for low- and middle-income country settings. This study focuses on the development of dissolving bilayer MAPs loaded with norelgestromin (NGMN) as a first step towards developing a future potential drug delivery system for sustained hormonal contraception. The fabricated MAPs were designed with the appropriate needle lengths to penetrate the stratum corneum, while remaining minimally stimulating to dermal nociceptors. Ex vivo assessments showed that the MAPs delivered an average of 176 ± 60.9 µg of NGMN per MAP into excised neonatal porcine skin, representing 15.3 ± 5.3% of the loaded drug. In vivo pharmacokinetic analysis in Sprague Dawley rats demonstrated a Tmax of 4 h and a Cmax of 67.4 ± 20.1 ng/mL for the MAP-treated group, compared to a Tmax of 1 h and a Cmax of 700 ± 138 ng/mL for the intramuscular (IM) injection group, with a relative bioavailability of approximately 10% for the MAPs. The MAP-treated rats maintained plasma levels sufficient for therapeutic effects for up to 7 days after a single application. These results indicate the potential of NGMN-loaded dissolving bilayer MAPs, with further development focused on extending the release duration and improving bioavailability for prolonged contraceptive effects.
RESUMEN
Sedentary lifestyles, work overload, and lack of regular physical activity are risk factors for spinal pain syndrome. In everyday medical practice, spinal pain syndrome of a muscular or myofascial, or non-neurogenic, nature is diagnosed. This problem affects a large group of patients and reaches about 70-80% of spinal pain cases. Usually, one of the primary treatments is with NSAIDs (Non-steroidal Anti-Inflammatory Drugs). In this case, one treatment method that is safe and has no side effects is spinal mesotherapy. This method consists of performing multi-point intradermal microinjections with the administration of drugs or medical devices. Based on a new perspective on the treatment of spinal pathology-the so-called three-stage treatment concept-it is necessary to deal with the risk factor(s) of spinal pain syndrome and reduce or at least modify them (stage I). This is followed by a broadly understood medical therapy, in this case spinal mesotherapy (stage II), which aims to relax tense tissues, improve mobility in the spine and thus reduce pain. As a result, conditions are created for the necessary process, which is rehabilitation in the broadest sense (stage III). Movement therapy, which is crucial in spinal pain syndrome, is performed with less pain, after obtaining better patient mobility. The purpose of this article is to evaluate the role of rehabilitation of patients after spinal mesotherapy in terms of the three-stage treatment concept for spinal pathology.
RESUMEN
BACKGROUND: Canine atopic dermatitis (cAD) is a hereditary, generally pruritic and predominantly T-cell-driven inflammatory skin disease, involving an interplay between skin barrier abnormalities, allergen sensitisation and microbial dysbiosis. The individual immunological response is predominantly against environmental allergens, including mite antigens; mould spores; and pollen from grasses, trees and weeds. Airborne pollens show fluctuating patterns during the year. OBJECTIVE: The aim of this prospective study was to evaluate the influence of local pollen concentrations and weather conditions on the clinical signs of atopic dogs, and to investigate any possible correlations with the results of intradermal testing (IDT). MATERIALS AND METHODS: Thirty-seven privately owned atopic dogs in Bavaria were surveyed from 1 April to 30 November 2021. Owners were asked to record pruritus using a validated Visual Analog Scale (PVAS) score and the weekly medication of their dog. Furthermore, weather data, including pollen count, rainfall, relative humidity, hours of sunshine and temperature from the dog's location were collected daily. RESULTS: Of the evaluated parameters, only humidity and medication scores correlated positively with the PVAS scores of the atopic dogs. There was no correlation between specific pollen counts and PVAS scores of dogs with positive IDT reactions to that pollen. CONCLUSION AND CLINICAL RELEVANCE: The outcome of this study highlights the importance of a careful interpretation of positive IDT results in dogs with cAD and questions the validity of airborne pollen trap methodology in representing pollen exposure for dogs at ground level.
RESUMEN
BACKGROUND: Limited information exists about the correlation between clinical history and positive serum (SAT) and intradermal allergen test (IDAT) results in atopic dogs. OBJECTIVES: To evaluate the correlation between clinical history and SAT/IDAT results in atopic dogs. ANIMALS: Twenty-nine client-owned dogs with nonseasonal atopic dermatitis with or without seasonal exacerbation were enrolled. MATERIALS AND METHODS: IDAT, SAT (immunoglobulin (Ig)M antibody capture enzyme-linked immunosorbent assay [MacELISA] with bromelain CCD inhibitor) and clinical information collected in a questionnaire regarding seasonal variations in pruritus affecting the dogs were performed on the same day. Two independent investigators (Inv A and Inv B) recorded IDAT results. RESULTS: The kappa coefficients agreement for positive IDAT scores between Inv A and B was substantial. The agreement between IDAT and SAT results at different ELISA absorbance units (EAU) cut-offs (>79 and ≥300) was slight and fair for both investigators, respectively. A higher agreement was observed between IDAT and SAT (≥300 EAU) than between IDAT and SAT (>79 EAU) with the exception of mite and flea allergens. There was a statistically significant association between clinical history and positive IDAT results for seasonal allergens (Inv A and Inv B, p = 0.016). There was no significance between positive SAT results and clinical history. Five (IDAT) and 12 of 13 (SAT) atopic dogs without clinical seasonal exacerbation showed positive results for seasonal allergens. CONCLUSIONS AND CLINICAL RELEVANCE: The agreement between IDAT and SAT ≥300 EAU results was fair and the agreement between IDAT and SAT >79 EAU results was slight for all allergens. Only positive IDAT results significantly correlated with clinical history.
RESUMEN
OBJECTIVE: To compare the clinical effect of intradermal needling and acupuncture in prevention and treatment of leukopenia after chemotherapy with spleen-kidney deficiency. METHODS: A total of 90 patients with malignant tumor who received chemotherapy were randomly divided into a intradermal needling group (30 cases, 1 case dropped out), an acupuncture group (30 cases, 2 cases dropped out, 1 case was eliminated) and a control group (30 cases). The control group received conventional symptomatic treatment after chemotherapy. On the basis of the treatment in the control group, the intradermal needling group received intradermal needling at Guanyuan (CV 4), Dazhui (GV 14) and bilateral Geshu (BL 17), Zusanli (ST 36)ï¼Shenshu (BL 23), the needles were retained for 48 h, once every other day. On the basis of the treatment in the control group, the acupuncture group received conventional acupuncture at the same acupoints as the intradermal needling group, once every other day. The treatment started from the first day of chemotherapy, for a total of 2 weeks in the three groups. The white blood cell count, neutrophil count, hemoglobin content, platelet count and Karnofsky performance status (KPS) score before treatment and on 3rd, 7th, 14th, and 21st days after treatment were compared among the three groups. The incidence and grading of leukopenia and the usage of leukocyte-boosting drug during chemotherapy cycle was recorded. RESULTS: On 7th day after treatment, the white blood cell count in the intradermal needling group and the acupuncture group was higher than that in the control group (P<0.01, P<0.05). On the 14th day after treatment, the hemoglobin content in the intradermal needling group and the acupuncture group was higher than that in the control group (P<0.01). On the 7th, 14th, and 21st days after treatment, the platelet count in the acupuncture group was higher than that in the control group (P<0.01), on the 14th and 21st days after treatment, the platelet count in the intradermal needling group was higher than that in the control group (P<0.01). There was no statistically significant difference among the three groups after treatment in terms of neutrophil count, KPS score, incidence and grading of leukopenia, and the usage of leukocyte-boosting drug (P>0.05). CONCLUSION: Both intradermal needling and acupuncture can effectively increase peripheral blood white blood cell count, hemoglobin content and platelet count during chemotherapy cycle, reduce the toxicity of chemotherapy drug to bone marrow hematopoietic function, and alleviate bone marrow suppression after chemotherapy. The two treatments are equally effective.

Syringocystadenoma papilliferum (SCAP) is a benign adnexal tumor commonly found on the scalp and face, and often associated with nevus sebaceous, with about half of cases appearing in early childhood. SCAP exhibits cystic invaginations with papillary structures and a double-layered glandular epithelium linked to the epidermal surface and stromal plasma cells. We are reporting a rare instance of intradermal SCAP in a 55-year-old male. He sought evaluation for a long-standing asymptomatic dark-pink papule in his left popliteal fossa, measuring 0.7 x 0.5 x 0.4 cm. A shave biopsy revealed papillary dermal fibrosis, glandular epithelium with apocrine secretion, and papillary projections without an epidermal connection. Infundibulofollicular keratinization was observed, along with stromal plasma cells. The patient chose local excision as the treatment option. This case highlights the rarity of intradermal SCAP, especially in the left popliteal fossa, with only one other reported case in the literature.

Purpose: Botulinum toxin has played a remarkable role in management of forehead wrinkles. Most used is intramuscular technique due to its deposition into the muscles, however, with adverse effects like brow ptosis. This study has been designed for the evaluation of efficacy for intradermal v/s intramuscular route of botulinum toxin injections for forehead wrinkles using clinical correlation. Methods: This study included a clinical trial of 32 facial halves divided equally into intradermal and intramuscular injection technique groups, receiving total dose of 8 U. Results were assessed by clinical examination upto 2 weeks and 4 weeks with parameters; objective wrinkle rate, eyebrow height, eyebrow movement, pain, and satisfaction after treatment. Result: Results showed least mean for objective wrinkle rate in intramuscular group, showing statistically significant improvement. Overall improvement in eyebrow height and eyebrow movement were slightly more for intramuscular group. Pain was lesser for intradermal group, whereas satisfaction of patient of patient post treatment is similar for both the groups. Conclusion: Among intradermal and intramuscular botulinum toxin injection technique, the effect and potency were better for intramuscular technique, whereas the patient comfort and compliance were better for intradermal technique.
