Adenocarcinoma in situ (ductal type) ex pleomorphic adenoma of the lacrimal gland.

Purpose: To present the clinical and histopathological characteristics of a rare case of ductal carcinoma in situ ex pleomorphic adenoma in the lacrimal gland. Observations: A 73-years-old Caucasian female presented with complaints of double vision and pain in the left eye region. Clinical examination revealed ptosis and exophthalmos of the left eye as well as diplopia on downward gaze. Magnetic resonance imaging of the left orbit demonstrated a 17 × 22 mm homogeneous tumor in the left lacrimal fossa. The tumor was excised in toto. Histopathological examination revealed a pleomorphic adenoma with ductal structures with benign looking epithelial cells, surrounded by myoepithelial cells. Tumor areas with cribriform architecture consisting of ductal structures with abnormal luminal epithelial cells and intact myoepithelial cell layer were also present. The surgical margins were clear. All luminal and myoepithelial cells were positive for cytokeratin 7, the luminal cells in the cribriform areas were positive for human epidermal growth factor 2 and androgen receptor. The myoepithelial cells were positive for cytokeratin 5, calponin and focally for glial fibrillar acid protein. The findings were diagnostic for ductal carcinoma in situ ex pleomorphic adenoma. Next generation sequencing Oncomine Comprehensive Assay mutation analysis found mutations in the BRCA2 (p.K3326*), BAP1 (p.S395*), and TP53 (p.E285K) genes in the ductal carcinoma in situ and BRCA2 (p.C9976A) in the pleomorphic adenoma part. Conclusion and importance: To our knowledge, this tumor is only the second described ductal carcinoma in situ ex pleomorphic adenoma of the lacrimal gland.

The effect of orally administered glycerol on anterior chamber depth during cataract surgery in eyes with narrow anterior chambers.

PURPOSE: Cataract surgery on eyes with shallow anterior chambers may be demanding. Glycerol intake prior to surgery has been a well-known method in an effort to increase anterior chamber depth. It is used since it is thought that glycerol as an osmotic agent causes the vitreous body to shrink, pulling back the iris and thereby deepening the anterior chamber - making the surgery easier. Our controlled clinical trial tests this hypothesis and investigates the effect of glycerol on anterior chamber depth (ACD), intraocular pressure (IOP), corneal thickness (CCT), pupil diameter change after viscodilation (PD), operating time and perioperative complications. METHODS: We performed a controlled clinical trial. All patients underwent cataract surgery on both eyes with at least 7 days apart. Preoperatively the patient was given glycerol orally when the right eye was operated - when the left eye was operated, nothing was given. In this way, each patient was serving as its own control. Measurements of ACD, IOP and CCT were performed before and after glycerol intake, pupillary diameter was measured before and after viscoelastics during the operation, and operating time and surgical complications were noted. RESULTS: The study included 22 patients with bilateral cataract and anterior chambers depth <2.5 mm. Glycerol caused the anterior chamber to increase by 0.022 mm (p < 0.05), and IOP was lowered by 5.1 mmHg compared to the control group (p < 0.05). However, exposure to glycerol showed no effect on CCT, pupillary dilation of viscoelastics, operating time or surgical complications. CONCLUSION: Glycerol increases anterior chamber depth and lowers intraocular pressure significantly. These changes had no significant impact on operating time nor on the complication rate, suggesting that these changes are too subtle to have a clinical impact on the cataract procedure.

Penetrating Orbital Sphenoid Sinus Trauma with a Wooden Stick: A Challenging Case Report.

Transorbital and intra-sphenoidal traumas are relatively uncommon, can be challenging to manage, and are associated with a high risk of complications and potentially fatal outcome. Transorbital and intra-sphenoidal trauma pose a medical challenge due to close relationship to delicate and critical anatomical structures, such as the globe, optic nerve, the ophthalmic internal carotid arteries, and central nervous system. Rapid admission to a level 1 trauma center with a high surgical expertise level is essential to ensure the best possible treatment and outcome. We present a case of a 75-year-old man who had a severe orbital trauma, where a wooden foreign object penetrated the orbit into the sphenoid sinus without penetrating its posterior wall. This case is important because of the rare trauma presentation with a wooden foreign object, which can easily be missed on computed tomography. The case also illustrates the importance of close collaboration between ophthalmologists and rhinologists when challenged with severe orbital sphenoid sinus trauma.

Lymphoplasmacytic lymphoma infiltrating both lacrimal glands in a patient with Waldenström's macroglobulinemia.

PURPOSE: To describe a case of Waldenström's macroglobulinemia/lymphoplasmacytic lymphoma with infiltration of both lacrimal glands. OBSERVATIONS: A 63-year-old male with Waldenström's macroglobulinemia was referred to the ophthalmological clinic due to intermittent bilateral painless swollen eyelids. The patient had slight bilateral chemosis along with swelling of both eyelids. A mechanical ptosis was present on both sides. Funduscopic examination and tonometry were normal. Computed tomography and positron emission tomography showed an enlargement of both lacrimal glands with positive PET signal, and hence a biopsy was performed for histological and cytogenetic examination. Histopathological examination revealed an infiltrate of lymphoplasmacytic cells and small lymphocytes within the lacrimal gland. The tumor cells stained positive for IgM and CD20, CD79, BCL-2, and kappa light chain. A cytogenetic examination revealed a mutation in MYD88 confirming Morbus Waldenström/lymphoplasmacytic lymphoma. CONCLUSIONS AND IMPORTANCE: Intermittent swollen lacrimal glands are a rather common symptom, and Morbus Waldenström/lymphoplasmacytic lymphoma should be considered as a differential diagnosis. This symptom should be carefully evaluated in Waldenström patients, as it can be a sign of disease progression in case of lacrimal gland involvement.

Periocular necrotizing soft tissue infection in Greater Copenhagen.

PURPOSE: Necrotizing soft tissue infection, also known as necrotizing fasciitis (NF), is a fast-spreading life-threatening infection that most commonly affects the lower limbs, groin, or abdomen. Periocular necrotizing fasciitis (PNF) is rare. Limited data exist on PNF immune cell subset; hence, this study aims to determine the representation of immune cell subsets in patients diagnosed with PNF using immunohistochemical stainings. METHODS: All patients diagnosed with PNF at Copenhagen University Hospital from 2008 to 2018 were included. Their electronic medical records and pathology reports were assessed, and available tissue specimens were reviewed and stained with monoclonal antibodies for CD1a+ Langerhans' cells, CD3+ T lymphocytes, CD15+ granulocytes, CD44+ lymphohematopoietic cells, CD68+ histiocytes, CD79α+ B lymphocytes, and FXIIIa+ dendritic macrophages and Langerhans' cells. The number of positive cells was counted, and an average score was calculated. The location of immune cells and bacteria was assessed. RESULTS: The specimens were characterized by acute inflammation and necrosis of the fascia, while striated muscle involvement was less frequent. Haemolytic group A streptococci and Staphylococcus aureus were identified and mainly located in the deep dermis and subcutis in close relation to the fascia. Only few areas harboured both bacteria and inflammatory cells. Granulocytes, histiocytes and CD44+ lymphohematopoietic cells were demonstrated to be abundant in all patients, while B and T lymphocytes, dendritic macrophages and Langerhans' cells were less frequent. CONCLUSION: The immune cell subsets found in this study of PNF were consistent with those identified in the literature on NF in other anatomical locations. This study concludes that immune cells are abundant and exhibit a typical pattern in PNF.

Lithium-Induced Downbeat Nystagmus and Horizontal Gaze Palsy.

We report a case of lithium-induced downbeat nystagmus and horizontal gaze palsy in a 62-year-old woman who was treated for a bipolar affective disorder with lithium carbonate for one month. At presentation serum lithium was within therapeutic range. No alternative causes of the ocular motility disturbances were found, and the patient improved significantly as lithium carbonate was discontinued.

Bilateral endogenous Fusarium solani endophthalmitis in a liver-transplanted patient: a case report.

INTRODUCTION: Endogenous Fusarium endophthalmitis is a rare disease predominantly described in immunocompromised patients often due to leukemia. We report a case of bilateral endogenous Fusarium solani endophthalmitis in a liver-transplanted patient. CASE PRESENTATION: A 56-year-old Danish Caucasian woman who had undergone two liver transplantations, developed endogenous endophthalmitis of her left eye 10 days after the second liver transplantation. Despite continuous therapy, enucleation of her left eye was eventually necessary; at this point funduscopic examination of her right eye disclosed a white inflammatory plaque at the macula consistent with a fungal infection. Microbiological analysis of vitreous fluid from her enucleated left eye revealed Fusarium solani, and light microscopy of her enucleated eye was consistent with Fusarium panophthalmitis with massive ingrowth of the fungi in all areas containing basement membrane collagen. Voriconazole was injected intravitreally in her right eye, and intravenous voriconazole was initiated. No subsequent growth in the inflammatory plaque was observed. She died 6 weeks after the endogenous endophthalmitis was diagnosed. CONCLUSIONS: This is the first report of endogenous Fusarium solani endophthalmitis in a liver-transplanted patient. Ophthalmologists and physicians dealing with liver transplantation should be aware of the potential for postoperative endophthalmitis due to rare microorganisms, such as Fusarium solani.

Corneal endothelial cell changes after cataract surgery in patients on systemic sympathetic α-1a antagonist medication (tamsulosin).

PURPOSE: The purpose of this study was to assess the incidence of intraoperative floppy iris syndrome (IFIS) and the morphology of the corneal endothelium after cataract extraction in Caucasian male patients exposed to the α-1a adrenergic receptor antagonist tamsulosin. METHODS: In a clinical prospective study, 23 male patients (23 eyes) treated with tamsulosin due to benign prostatic hyperplasia and 25 male patients (25 eyes) with no tamsulosin treatment had cataract surgery. The divide-and-conquer technique was used with the Infinity OZil(®) machine. A combination of Healon and Healon5 was used in all patients, but the use of additional Vision Blue, iris retractors or intracameral phenylephrine in the tamsulosin group was at the discretion of the surgeon. The endothelial cell density, variation in endothelial cell size (CV), percentage of hexagonal cells and central corneal thickness (CCT) were recorded at baseline and at 3 months postoperatively. RESULTS: In the tamsulosin-treated group, 19 of 23 eyes (83%) developed IFIS, compared with no IFIS in the control group. Compared with the control group, the tamsulosin group showed significantly less dilatation at the start of the operation, significant miosis during surgery and significantly greater corneal endothelial cell loss 3 months postoperatively (12% versus 3%; p< 0.001). CONCLUSION: Intraoperative floppy iris syndrome during cataract surgery is significantly associated with tamsulosin-treated male patients. Patients on tamsulosin showed less preoperative dilatation, significant miosis during surgery, and had significantly greater postoperative endothelial cell loss compared with nontreated patients despite recommended precautions.

Long-term associations between serum lipids and panretinal photocoagulation in type 1 diabetes.

AIMS: To examine the predictive value of serum lipids on the need for panretinal photocoagulation (PRP) treatment in a long-term follow-up of a cohort of Danish type 1 diabetic patients. METHODS: A total of 243 type 1 diabetic patients were included from a population-based cohort. Of these, 25 patients (10.3%) were excluded due to proliferative diabetic retinopathy (PDR) at baseline. The remaining 218 patients were followed from January 1993 to November 2006. Serum levels of lipids were collected at baseline. PRP treatment was considered as indicative of PDR during follow-up, and the date of PRP was documented from the Danish National Patients Registry. RESULTS: At baseline, the median age and duration of diabetes were 45.9 years (range 23.9-78.4 years) and 30 years (range 20-72 years), respectively. In the crude analysis, serum triglyceride was associated with incident PRP. However, after adjustments for baseline age, sex, duration of diabetes and HbA1c, this was no longer statistically significant, although a clear trend was found (hazard ratio 1.40, 95% confidence interval 0.97-2.03, p = 0.07, for each 1 mmol/L increase in serum triglyceride). Total cholesterol, HDL cholesterol and LDL cholesterol were not associated with a higher risk of incident PRP. CONCLUSIONS: In a 13-year follow-up of a population-based cohort of long-term type 1 diabetic patients, there was a trend of an association between serum triglyceride and subsequent need of PRP treatment, which was used as a surrogate endpoint of PDR. This identifies triglycerides as a potential risk factor of PDR in type 1 diabetes.

[The importance of hygiene for hospital infections]. / Rengøringens betydning for forekomst af hospitalsinfektioner.

Hospital cleaning is a neglected part of infection control. Due to financial constraints and lack of clinical evidence it has been cut down to the bare minimum and currently-used methods are unfit for the removal of microorganisms. Recent studies indicate that MRSA and other important pathogens may be transmitted to patients from the hospital environment. Furthermore, studies suggest that intensified cleaning may lower the risk of transmission. There is an urgent need for more clinical evidence and for development of standards and methods which focus on the removal of pathogens from the hospital environment.
