A 26-year-old woman presented an eyelid lesion, after being scratched by a cat that had a similar skin lesion. It evolved into a cervical lymph node enlargement. With a hypothesis of Parinaud´s oculoglandular syndrome (POS) due to cat scratch disease (CSD), doxycycline was prescribed. After two weeks of treatment without improvement, a biopsy and blood sample were obtained. Itraconazole was prescribed and the skin lesion improved, but not the lymph node enlargement. A Sporothrix schenckii complex was isolated from the skin sample. Also, a specie-specific polymerase chain reaction detected Bartonella henselae DNA in her blood sample. Azithromycin was included to treat the bacterial infection, whereupon the lymph node also receded successfully. Sporotrichosis and CSD are zoonoses that can be transmitted to humans by traumatic inoculation due to scratches or bites from cats. Both can evolve with POS. Patients who present skin lesions and/or POS after being wounded by a cat should be investigated for both diseases.

A 71-year-old male had disseminated multiple organ dysfunction syndrome (MODS). Following treatment with cefotaxime and piperacillin-tazobactam, his symptoms have worsened instead. Multiple organ failure caused by Japanese Spotted Fever (JSF) was diagnosed based on metagenomic next-generation sequencing (mNGS), we rapidly treated the patient with doxycycline. Thereafter, his symptoms gradually improved. In this report, we emphasized the importance of rapid microbial diagnostic tools and the early use of tetracyclines for the treatment of JSF.

A widely accepted set of imaging criteria or classification has not yet been adopted to evaluate response to treatment by percutaneous sclerotherapy for aneurysmal bone cyst (ABC). In this article, we described and illustrated the Royal Orthopaedic Hospital (ROH) scoring system which is a new, reproducible, and objective tool to evaluate the radiological response. We also reported our institutional experience in the efficacy of computed tomography (CT)-guided sclerotherapy for treating such lesions. A retrospective analysis was conducted for 19 patients who underwent CT-guided sclerotherapy with doxycycline and albumin to treat ABC. Follow-up magnetic resonance imaging, at a minimum of 12 months, was assessed according to the four ROH scoring system parameters: cystic component, fluid-fluid level, presence of consolidation, and cortical integrity. The cumulative score was used to grade response as either: excellent, good, equivocal, or poor. Out of 19 patients with a mean age of 17.8 years, 11 cases occurred in the long bones, 5 cases in the pelvis, and 1 in each of the C3 vertebral body, scapula, and talus. The mean parameter of response score for cystic component was 2, fluid-fluid level was 1.3, consolidation was 2, and cortical integrity was 2.1. Four cases showed excellent response, 12 cases showed good response, 2 cases showed equivocal response, and 1 case showed poor response. Interrater reliability was excellent (κ = 0.9). The ROH scoring system provides the radiologist and surgeon with an objective method to score imaging parameters of response independently and achieve a grade based on the cumulative score.

OBJECTIVE
Acne is a chronic inflammatory disease that involves the pilosebaceous follicle. Its pharmacological treatment involves topical and systemic medications, but a heterogeneous group of drugs may exacerbate or induce skin lesions. The aim of this study was to identify the pharmacological management and medications related to the exacerbation of skin lesions in patients diagnosed with acne.
METHODS
This was a cross-sectional study that identified the outpatient medication prescription patterns of patients with acne from a dispensing database of 8.5 million members of the Colombian Health System. Sociodemographic and pharmacological variables and the identification of prescriptions that were potentially inappropriate due to the risk of worsening acne were considered.
RESULTS
A total of 21,604 patients with acne were identified. Median age was 20.8 years (interquartile range: 17.3-27.3 years), and 60.7 percent were female. Treatment mainly involved antibiotics (79.9% of patients), especially doxycycline (66.0%), and retinoids (55.7%). A total of 17.2 percent of patients had potentially inappropriate prescriptions, predominantly progestogens with androgenic properties (8.9%). Female patients (odds ratio [OR]: 3.55; 95% confidence interval [CI]:3.24-3.90) and patients with pathologies such as systemic lupus erythematosus (OR: 18.61; 95% CI: 7.23-47.93) and rheumatoid arthritis (OR: 10.80; 95% CI: 5.02-23.23) were more likely to receive inappropriate prescriptions, and the risk increased with each year of life (OR: 1.02; 95% CI: 1.02-1.03).
LIMITATIONS
Access to medical records was not obtained to verify clinical characteristics of acne.
CONCLUSION
Patients with acne are excessively treated with systemic antibiotics, counter to clinical practice guidelines. Approximately one-fifth of these patients received some potentially inappropriate medication that could exacerbate their skin lesions.

Brucellosis, a systemic infection, can affect various organs, including the genitourinary system, causing epididymo-orchitis in 2%-20 % of cases. This report details a 34-year-old Thai male migrant worker with febrile orchitis. Initial gentamicin treatment failed, but serological tests confirmed brucellosis, likely from raw dairy consumption. The patient was successfully treated with gentamicin, doxycycline, and rifampicin, resulting in complete symptom resolution. Brucella orchitis, though rare, should be considered in patients from endemic areas. Conservative treatment with combined antibiotics is typically effective.

Development of a new synchronous fluorescence spectrometry combined with Al sensitized for simultaneous and rapid determination of trace flumequine, ciprofloxacin and doxycycline hydrochloride residues in wastewater.
Antibiotics are a new type of environmental pollutants. Due to its wide application in many fields, antibiotic residues are ubiquitous in the wastewater environments. Given their potential threat on water ecosystem functioning and public health, the detection of antibiotic residues in wastewater environments has become very necessary. Based on the complexation of Al with flumequine (FLU), ciprofloxacin (CIP) and doxycycline hydrochloride (DOX), their molecular conjugated area were increased and fluorescence intensity were enhanced, combined with synchronous fluorescence spectrometry (SFS) had good selectivity and high sensitivity, a novel method of Al sensitized synchronous fluorescence spectrometry for the determination of FLU, CIP and DOX residues in wastewater was established. When the wavelength difference (Δλ) was selected 115.0 nm, synchronous fluorescence spectra of the three antibiotics could be well separated and the interference of wastewater matrix were eliminated primely. The new SFS made good use of spectral separation instead of conventional chemical separation, and the actual wastewater sample could be directly determined after simple filtration. The experiment results showed that the concentrations of FLU, CIP and DOX in the range of 0.5000-800.0 ng·mL, 0.5000-640.0 ng·mL and 10.00-3500 ng·mL had a good linear relationship with fluorescence intensity. The detection limits of three antibiotics were 0.02054 ng·mL, 0.03956 ng·mL and 0.8524 ng·mL, respectively. Recovery rates of three antibiotics in wastewater samples were 90.72%-98.23%, 88.68%-95.08% and 85.94%-96.70%. The new SFS established in this experiment had the advantages of simple, rapid, sensitive, accurate and good selectivity. Simultaneous and rapid detection of FLU, CIP and DOX residues in wastewater was successfully realized. It had good application prospects in real-time water quality monitoring.

Review
BACKGROUND
Nocardia is an ubiquitous soil organism. As an opportunistic pathogen, inhalation and skin inoculation are the most common routes of infection. Lungs and skin are the most frequent sites of nocardiosis. Testis is a highly unusual location for nocardiosis.
CASE PRESENTATION
We report the case of an immunocompromised 75-year-old-man admitted for fever of unknown origin. He presented with skin lesions after gardening and was first suspected of Mediterranean spotted fever, but he did not respond to doxycycline. Then, physical examination revealed new left scrotal swelling that was compatible with a diagnosis of epididymo-orchitis. The patient's condition did not improve despite empirical antibiotic treatment with the onset of necrotic scrotal abscesses requiring surgery. Nocardia brasiliensis yielded from the removed testis culture. High-dose trimethoprim-sulfamethoxazole and ceftriaxone were started. Multiple micro-abscesses were found in the brain and spinal cord on imaging studies. After 6 weeks of dual antibiotic therapy for disseminated nocardiosis, slight regression of the brain abscesses was observed. The patient was discharged after a 6-month course of antibiotics and remained relapse-free at that time of writing these lines. Trimethoprim-sulfamethoxazole alone is meant to be pursued for 6 months thereafter. We undertook a literature review on previously reported cases of genitourinary and urological nocardiosis; to date, only 36 cases have been published with predominately involvement of kidney, prostate and testis.
CONCLUSIONS
To the best of our knowledge, this is the first case of Nocardia brasiliensis simultaneously infecting skin, testis, brain and spinal cord in an immunocompromised patient. Knowledge on uncommon forms of nocardiosis remains scarce. This case report highlights the difficulty of diagnosing atypical nocardiosis and the importance of prompt bacteriological sampling in case of empirical antibiotics failure.

INTRODUCTION
The scarcity of epidemiological data on acute febrile illnesses from South Asia impairs evidence-based clinical decision-making. Our study aimed to explore the etiological spectrum of short-duration fever in patients admitted to a tertiary care hospital in West Bengal, India.
METHODS
We conducted a cross-sectional study from May 2021 to April 2022 involving 150 adult patients presenting with a fever lasting less than two weeks at Burdwan Medical College and Hospital (West Bengal, India). We performed comprehensive clinical assessments, including microbiological, serological, and other specific investigations, to identify the causes of the fever.
RESULTS
The demographic profile predominantly included individuals aged 21-40 years, with a male-to-female ratio of 1.9:1; 60.7% of participants were from rural areas. The primary etiological agents identified were scrub typhus (25.3%), dengue (15.3%), and enteric fever (13.3%). Notably, 80% of patients presented with non-localizing symptoms, while 14.7% had respiratory symptoms. Blood cultures pinpointed Salmonella typhi and Staphylococcus aureus in a minority of cases (3.3%); malaria, primarily Plasmodium vivax, was diagnosed in 12% of the cases.
CONCLUSION
Our findings highlight the complexity of diagnosing short-duration fevers, dominated by a wide range of etiological agents, with a notable prevalence of scrub typhus. These results underscore the urgent need for enhanced diagnostic facilities, including the availability of scrub typhus testing at primary healthcare centers. We recommend empirical doxycycline therapy for suspected cases and emphasize the need for further research to develop management guidelines for acute febrile illnesses. This study also highlights the importance of raising both community and clinician awareness to prevent irrational antibiotic use.

Review
Rosacea is a chronic inflammatory skin disease of the central face, affecting 5% of the population. The exact etiology is unknown. A diagnosis is made based on the updated 2017 National Rosacea Society Expert Committee guidelines, including fixed erythema, phymatous changes of skin thickening due to sebaceous gland hyperplasia and fibrosis, papules, pustules, telangiectasia, and flushing. Delays in an accurate diagnosis and treatment may occur in skin of color due to difficulty visualizing erythema and telangiectasia. The daily use of sunscreen, moisturizers, and mild skin cleansers and avoidance of triggers are essential aspects of maintenance treatment. Effective topical treatment options include alpha-adrenergic receptor agonists for flushing and ivermectin, metronidazole, and azelaic acid for papules and pustules. Systemic treatments include nonselective beta blockers for flushing, low-dose doxycycline, and isotretinoin for papules and pustules. Rosacea can significantly affect a patient's emotional health and quality of life. A referral for care is recommended for fixed phymatous changes and ocular rosacea.
