A case of post-operative agranulocytosis which occurred in a 66-year-old woman following surgery for endometrial carcinoma is reported. The agranulocytosis had a rapid onset, being detected on the first post-operative day. The causative agent, cefazolin was given to the patient intraoperatively. The agranulocytosis persisted until the 22nd postoperative day. A bone marrow biopsy performed on post-operative day four showed a left-shifted myeloid maturation pattern but not a maturation arrest. The pathogenesis of drug-induced neutropenia/agranulocytosis is discussed. It is postulated that reversible binding of cefazolin to albumin accounts for the prolonged duration of agranulocytosis.

Pseudofungus structures in lymph node tissues have been reported on multiple occasions. Despite a variety of investigative tests including histochemical special stains and energy dispersive spectral analysis, the underlying nature and origin of these pseudofungus structures has never been clearly defined. The most common hypothesis suggests that they represent collagen fibers that become coated with iron and calcium. Herein, evidence is given that the pseudofungus structures identified in the lymph node tissues represent fragments of polyurethane catheters. The evidence includes both a comparison of these pseudofungus structures to fragments of polyurethane well documented in the literature and a comparison of polyurethane catheter scrapings to the pseudofungus structures identified in the literature. In both of these comparisons, the morphology of the polyurethane fragments are identical to the pseudofungus structures. This is the first definitive report identifying polyurethane catheter fragments as representing the true nature and etiology of pseudofungus structures in lymph node tissues.

Treatment options in multiple myeloma (MM) based on novel agents are often limited by dose-related neurotoxicity. Bortezomib, a highly active reversible proteasome inhibitor, frequently causes peripheral neuropathy (PN). Bortezomib-induced PN (BIPN) is characterized by a length-dependent, sensory, axonal polyneuropathy (PNP) with predominant small fiber-affection. Following dose reduction or drug discontinuation, BIPN resolves within 3-4 months in the majority of patients. The pathophysiological mechanisms of BIPN are unclear. Rare cases of a severe demyelinating or mixed BIPN with prominent motor involvement have been attributed to autoimmune or inflammatory reactions. A case report, including nerve pathology, is presented of a 59-year-old man with stage III IgG-κ MM who was treated with bortezomib on the occurrence of progressive disease. After the fourth cycle, he developed a painful distal symmetric sensory PNP followed by gait instability and muscle weakness increasing over 3 months despite early cessation of bortezomib. Neurological examination revealed a distal flaccid tetraparesis mainly of the lower limbs with sensory loss and severe ataxia, electrophysiological features of a mixed axonal-demyelinating PNP, and pathomorphological evidence of neuritis. Steroid treatment was initiated, and partial recovery of the neurological symptoms within 6 months was observed. While a neurotoxic effect may explain the initial distal sensory disturbances, the worsening of neurological dysfunction after bortezomib withdrawal and the clinical pattern with steroid-responsive muscle weakness predominantly of the legs are consistent with an immune-mediated mechanism. This is in line with the sural nerve biopsy findings. Toxic BIPN followed by an immune-mediated BIPN in the same patient has not been reported before.

Purpose: To evaluate the presentation and outcome of periocular capillary hemangioma treated with low-dose oral propranolol. Method: Thirty cases of periocular capillary hemangioma prospectively studied from 1st June 2015 to 31st May 2017 who received oral propranolol on an outpatient basis. Hemangioma causing any threat to vision or disfigurement was included and age below 3 months and multiple lesions were excluded. Starting dose of propranolol was 1 mg/kg and increased to 2 mg/kg after 2 weeks as a maintenance dose. The tapering dose was 1 mg/kg of body weight before discontinuing the medication. Treatment was continued till the child is 1 year of age or no further change in color or size of the lesion in two successive follow-ups. Results: Presenting age was 6.36 ± 3.36 months (ranged 3–24 months) with female predominance (70%). In 86.6% of cases, the vision was Central Steady and Maintained and cycloplegic refraction showed marked astigmatism in 3 children which resolved after treatment. Forty-six percent of children showed color change as an initial response to treatment. Most children (33.3%) responded completely within 5 months after starting the treatment. One third patients (33.3%) showed 100% resolution, 50% showed 90% to 70% resolution. Pretreatment and post-treatment lesion size was1.60 ± 0.86 cm2 and 0.30 ± 0.40 cm2 respectively (p - value < 0.0005). None showed any significant adverse effect of oral propranolol. Conclusion: Low-dose oral propranolol is an effective and cost-effective treatment modality for periocular capillary hemangioma and is safe as an outpatient basis.

A 69-year-old man presented with a one-month history of a painful mass in the right breast. Pathologic evaluation of the excision of the mass revealed a proliferation of both glandular and stromal elements consistent with gynecomastia. In addition, histologic examination revealed peripheral nerves in the deep portion of the specimen were entrapped in the proliferative changes associated with gynecomastia. It is proposed that the expansile proliferation led to compressive pressure on the nerves and caused the pain associated with gynecomastia.

SARS-CoV-2 a virulent disease that established the entire wide world due to its severity. Its 1st case was rumored in Wuhan, China within the year 2019 and it had been the beginning of this pandemic. This virus killed virtually a complete of 4,465,683 folks round the globe until date. Despite the fact that viral co-infections have the ability to alter the host’s illness pattern, few research have looked at the disease outcomes in patients who are infected with HIV and hCoVs. Despite the fact that HIV-positive people can be infected with hCoVs, researchers are now revealing that their chances of acquiring serious CoV-related disorders are typically similar to what is seen in the general population. The relation between SARS-CoV-2 and HBV was summarized rather HBV effects the severity of COVID patient or not. SARS-CoV-2 could be a severe acute metabolic process syndrome. Scientists found ways in which to treat this virus, some were useful and alternative weren’t that a lot of effective. Immunizing agent was one among the most important considerations for the entire world. This virus conjointly fashioned an entry for alternative co-infections too. SARS-CoV-2 and influenza virus, both causes respiratory diseases which confer as an extensive array of illness from asymptomatic or benign to critical disease and death. Also the mode of transmission and symptoms of influenza virus and SARS-CoV-2 are same. Viral and bacterial rate is higher in SARS-CoV-2 negative patient but are comparable. Serologies facts confirmed that patients with effective results for dengue virus (DENV) NS1 antigen and anti-dengue IgM were also attentive to COVID-19 speedy antibody tests, suggesting dengue COVID-19 co-infection. Mixed infection of dengue and COVID-19 needs unique interest from all dengue-common nations in Asia, especially the ones with limited resources. To our knowledge, this is the primary showed case of co-infection of dengue and COVID-19 in Indonesia. During patient’s TB course, COVID-19 can occur at any time with worse consequences for the patients who are affected by active pulmonary disease.

Psoriasis is a chronic inflammatory skin disease with a complex mechanism, which is believed to be mainly based on immune disorders and activation of inflammatory pathways. However, we have combed through the literature and found that the pathogenesis of psoriasis might involve a “mobius loop” of “immunity-inflammation-oxidative stress-proliferation” process. The disordered immune environment of the skin might act as the basis, the outbreak of inflammatory factors as the mediator, and the imbalance of oxidative stress homeostasis as the activator. These factors work together, leading to abnormal proliferation of keratinocytes and further immune abnormalities, finally aggravating psoriasis. Therefore, here we review the latest evidence and advance in the pathogenesis of psoriasis, trying to contribute to further understanding and treatment of psoriasis.

We report a case of a right gluteal mass from the sacroiliac joint to the knee of an infant girl. Biopsy showed histopathological features similar to infantile fibrosarcoma (IFS). However, unlike most IFS, no ETV6-NTRK3 fusion gene abnormality was detected. Molecular analysis with TruSight RNA Pan-Cancer Panel detected the presence of KIAA1549-BRAF translocation and an oncogenic NF2p.Q459* SNV with potential clinical significance. A review revealed that the combination of this patient’s tumor site with the presence of a KIAA1549-BRAF translocation abnormality and an accompanying single nucleotide variant has not been previously described. The detection of this translocation abnormality raises the possibility that the spindle cell tumors in infants with an absence of the ETV6-NTRK3 fusion gene abnormality might have a distinct pathogenetic mechanism different from the previously known IFS and congenital mesoblastic nephroma. Furthermore, the discovery of BRAF translocation and its aberrant signaling of the mitogen-activated protein kinase (MAPK) pathway in this tumor contributes to the promise of clinical benefit of using the MEKi trametinib for the treatment of progressive disease that is refractory to conventional chemotherapy.

Flow cytometry (FCM) is a unique technique that allows rapid quantitative measurement of multiple parameters on a large number of cells at the individual level. FCM is based on immunolabelling with fluorochrome-conjugated antibodies, leading to high sensitivity and precision while time effective sample preparation. FCM can be performed on tissue following enzymatic or mechanical dissociation. The expression of epithelial antigens and cytokeratin isoforms help in distinguishing tumor cells from adjacent epithelial cells and from tumor infiltrating leukocytes. Tumor phenotypes can be characterized on expression intensity, aberrancies and presence of tumor-associated antigens as well as their cell proliferation rate and eventual heteroploidy. FCM can measure quantitative expression of hormone or growth factor receptors, immunoregulatory proteins to guide adjuvant therapy. Expression of adhesion molecules tells on tumor’s capacity for tissue invasion and metastasis seeding. Tumor heterogeneity can be explored quantitatively and rare, potentially emerging, clones with poor prognosis can be detected. FCM is easily applicable on fine needle aspiration and in any tumor related biological fluids. FCM can also be used to detect circulating tumor cells (CTC) to assess metastatic potential at diagnosis or during treatment. Detecting CTC could allow early detection of tumors before they are clinically expressed although some difficulties still need to be solved. It thus appears that FCM should be in the pathologist tool box to improve cancer diagnosis, classification and prognosis evaluation as well as in orientating personalized adjuvant therapy and immunotherapy. More developments are still required to better known tumor phenotypes and their potential invasiveness.

Currently, the emergence of highly virulent mutants in Europe and the United States has caused refractory recurrent Clostridium difficile infection (RCDI) to be a problem in clinical practice. In 2013, the Netherland group demonstrated breakthrough therapeutic efficacy in fecal microbial transplant (FMT) treatment clinical trials for RCDI, and FMT treatment is rapidly gaining attention. In addition to RCDI, FMT treatment has been attempted in various gastrointestinal diseases such as inflammatory bowel disease, irritable bowel syndrome and chronic constipation, as well as extragastrointestinal diseases. In this review, I would like to describe the current status, complications and prospects of FMT treatment.
