BACKGROUND/AIMS: This study investigated the clinical and pathological features of immunoglobulin G4 (IgG4)-related ophthalmic disease. To clarify the features, we compared IgG4-related ophthalmic disease and orbital inflammatory pseudotumor. METHODS: We retrospectively reviewed the medical records of 103 patients who were initially diagnosed with orbital inflammatory pseudotumor, and identified 16 cases in which the diagnosis was based on surgical biopsy and for which data in medical records were sufficient for analysis. Immunohistochemical staining of pathological specimens for IgG and IgG4 was performed. Finally, six of IgG4-related ophthalmic disease patient and 10 of orbital inf lammatory pseudotumor patient were analyzed. RESULTS: The IgG4-related ophthalmic disease group had more IgG4-positive plasma cells and a higher IgG4/IgG plasma cell ratio than the orbital inflammatory pseudotumor group. Collagenous fibrosis and lacrimal gland involvement were significantly more frequent in the IgG4-related ophthalmic disease group. Dense lymphocyte infiltration, obliterative phlebitis, and bilateral lesions were more frequent in IgG4-related ophthalmic disease, but the differences were not significant. The recurrence-free period was shorter in the IgG4-related ophthalmic disease group (p = 0.035). CONCLUSIONS: The location of the lesion (lacrimal gland), count and ratio of IgG4-positive plasma cells, and collagenous fibrosis aid the diagnosis of IgG4-related ophthalmic disease in patients with idiopathic orbital mass-like lesions. In addition, maintenance therapy should be considered in patients with IgG4-related ophthalmic disease to prevent recurrence.

Type 1 autoimmune pancreatitis (AIP1) is an IgG4-related systemic disease that mimics tumors. We report a rare case of AIP1 accompanied by mucinous cystic neoplasm (MCN). A pancreatic lesion was incidentally detected in a woman in her 60s. After 6 years of follow-up, the lesion abruptly increased in size. Computed tomography showed a 3.5 cm unilocular cyst in the tail of the pancreas and distal pancreatectomy was performed. On microscopic examination, the cyst was lined by mucinous and non-mucinous epithelial cells with mild cytologic atypia. The surrounding stroma comprised ovarian-type spindle cells with progesterone receptor positivity. The pericystic pancreas exhibited multifocal lymphoid follicles, lymphoplasmacytic infiltrations, obliterative phlebitis, and storiform fibrosis. IgG4-positive plasma cell infiltration (215 cells high-power field) and the IgG4/IgG ratio (57%) were increased. Cases of MCN coexisting with AIP1 are extremely rare; only two such cases have been reported in the English-language literature. This third case featured low-grade MCN with AIP1.

IgG4-related disease is a systemic inflammatory disease and is known as IgG4-related lung disease (IgG4-RLD) when it involves the respiratory system. Primary lung cancer arising from a background of IgG4-RLD is very rare. Herein, we report a case of adenosquamous carcinoma arising from the background of IgG4-RLD and presenting as an interstitial lung disease pattern. A 66-year-old man underwent lobectomy under the impression of primary lung cancer. Grossly, the mass was ill-defined and gray-tan colored, and the background lung was fibrotic. Microscopically, tumor cells showed both squamous and glandular differentiation. Dense lymphoplasmacytic infiltration with fibrosis and obliterative phlebitis were seen in the background lung. IgG4 immunohistochemical stain showed diffuse positivity in infiltrating plasma cells. Primary lung adenosquamous carcinoma has not been reported in a background of IgG4-RLD. Due to the rarity of IgG4-RLD, physicians must follow patients with IgG4-RLD over long periods of time to accurately predict the risk of lung cancer.

PURPOSE: The study aimed to examine the efficacy of the I.V. House UltraDressing for protecting peripheral intravenous catheters (PIVCs) in pediatric patients.METHODS: This randomized controlled trial comprised 60 pediatric patients (aged 2e24 months): 30 in the experimental group and 30 in the control group. The PIVC dwell time and phlebitis scores were also reported for both groups. The degree of phlebitis was determined using the Visual Infusion Phlebitis Scale (VIPS) and was recorded every 8 hours from the start of antibiotic therapy until catheter removal.RESULTS: The mean catheter dwell time in the experimental group (2.10 ± 1.55 days) was significantly longer than that in the control group (1.27 ± 0.45 days) (p < .01). However, there were no significant differences between the scores and signs of phlebitis in both groups (p > .05).CONCLUSION: The I.V. House UltraDressing is a useful device that can be used to increase catheter dwell time and protect and stabilize PIVCs in pediatric patients.

Immunoglobulin G4-related hypertrophic pachymeningitis (IgG4-RHP) is an increasingly recognized manifestation of IgG4-related disease (IgG4-RD), which is a fibroinflammatory condition that can affect virtually any organ. The three hallmark histopathological features of IgG4-RD are lymphoplasmacytic infiltration of IgG4-positive plasma cells, storiform fibrosis, and obliterative phlebitis. We report a case of biopsy-confirmed IgG4-RHP that was initially misdiagnosed as cerebral venous thrombosis.

OBJECTIVE: To compare the effect on Total Aerobic Count (TAC) of application of Isopropyl alcohol, Chlorhexidine, and povidone iodine plus alcohol prior to venipuncture and development of phlebitis in children admitted at a tertiary hospital.

METHODS: A prospective randomized clinical trial in a tertiary hospital in Quezon City. A total of 129 patients one-year old and above with physician orders for IV insertion and extractions. Pre and post swabbing of the venipuncture site was done and placed on a blood agar plate. The three antiseptic solutions were applied over the venipuncture site and swabbed and placed on the agar plate. The primary outcome measure was the TAC in each blood agar of the tested antiseptic solution and correlation to developing phlebitis.

RESULTS: The CFU/mL after disinfection was significantly different between groups, with the lowest CFU/mL observed among patients disinfected with Chlorohexidine. Phlebitis was only noted in the alcohol group. No reactions were observed from patients who were disinfected with povidone iodine and chlorohexidine.

CONCLUSIONS: Single application of Chlorhexidine is the optimal method to be used as antisepsis prior to procedures like venipuncture. However, the use of povidone iodine plus 70% isopropyl alcohol also has comparable effect to Chlorhexidine.

Isolated gastric IgG4-related disease (IgG4-RD) is a very rare tumefactive inflammatory condition, with only a few cases reported to date. A 48-year-old woman was incidentally found to have a subepithelial tumor in the stomach. Given a presumptive diagnosis of gastrointestinal stromal tumor or neuroendocrine tumor, she underwent wedge resection. The lesion was vaguely nodular and mainly involved the submucosa and proper muscle layer. Microscopically, all classical features of type I autoimmune pancreatitis including lymphoplasmacytic infiltration, storiform fibrosis, obliterative phlebitis, and numerous IgG4-positive plasma cells were seen. She had no evidence of IgG4-RD in other organs. Although very rare, IgG4-RD should be considered one of the differential diagnoses in the setting of gastric wall thickening or subepithelial mass-like lesion. Deep biopsy with awareness of this entity might avoid unnecessary surgical intervention.

Vinorelbine, a vinca alkaloid anticancer drug, is widely used to treat various cancers. Several dermatological side effects of vinorelbine, such as acral erythema, phlebitis, and severe extravasation reactions, have been reported. Vinorelbine is categorized as non-DNA binding vesicant that undergoes high metabolism and clearance, which limits the degree of tissue injury if extravasation occurs. A 73-year-old male presented with erythematous linear patches on his left wrist and a 51-year-old male presented with erythematous eroded patches and bullae on his right forearm. Histopathologic study showed interface changes with basal vacuolar degeneration and epidermal dysmaturation. Separation of the dermis from the epidermis was observed, as well as interstitial and perivascular inflammatory infiltrates in the dermis. Both patients were being treated with vinorelbine for lung cancer. Before the onset of the skin lesions, accidental intravenous extravasation of vinorelbine had occurred. Herein, we report two cases of chemotherapy induced drug reaction due to extravasation of vinorelbine.

Immunoglobulin (Ig) G4-related disease was recently recognized as a systemic fibro-inflammatory disease characterized by dense lymphoplasmacytic infiltrates, storiform fibrosis, and obliterative phlebitis with IgG4-positive cells in the target tissues. This disease can localize to a single organ or be diffuse in multiple organs. Pulmonary manifestation in IgG4-related lung disease presents as various sized nodules, lung masses, patchy ground-glass opacities, consolidation, thickened bronchovascular bundles, nodular pleural lesions, and interstitial lung disease. Traditional treatment for IgG4-related lung disease includes systemic (cortico) steroids. Here, we report a case of IgG4-related lung disease presenting as multiple cavitary nodules that spontaneously regressed without systemic steroid use.

Peripheral Intravenous Catheters (PIC) are widely used. Nurses are required to possess appropriate knowledge and practice. The present study aimed to determine nurses' knowledge and practice towards care of PIC. A cross-sectional descriptive study was conducted and 84 respondents participated in the study. A 26-item questionnaire comprising 11 items on knowledge and 15 items related to nursing practice was adapted and modified. The findings reported higher mean score from specialty unit respondents, with knowledge (M = 49.19, SD = 3.44) and practice (M = 66.38, SD = 5.15), compared to medical surgical wards with knowledge (M = 46.25, SD = 4.68) and practice (M = 63.17, SD = 4.63) towards the care of PIC, which was significant (p value = 0.010 and p value = 0.009, respectively). The study indicated a higher mean score of charge nurse respondents as compared with registered nurse with knowledge (M = 49.68, SD = 3.23); (M = 46.20, SD = 4.62) and practice (M = 67.11, SD = 4.84); (M = 63.06, SD = 4.61), which was significant (p value = 0.003 and p value = 0.001, respectively). There were no significant differences between respondents’ education qualification towards care of PIC with p > 0.05. However, the findings reported that respondents who possessed Bachelor of Nursing were deemed to score slightly higher in their knowledge and practice towards the care of PIC. In conclusion, the specialty unit and charge nurse respondents were deemed to possess better knowledge and practice towards the care of PIC in the hospital.
