Purpose: This study aimed to determine risk factors, and describe management and outcomes in patients who developed orbital cellulitis secondary to dacryocystitis. Methods: Multicenter retrospective case series with 18 patients and review of published cases. Results: The mean age was 62 years, 56% were female and 50% had recurrent dacryocystitis. Visual acuity was reduced in the affected eye with a mean of 0.27 logMAR (Snellen 20/40) which improved to 0.15 logMAR (Snellen 20/30) at final follow up. Two cases (12%) had dacryoliths and 1 patient had sarcoidosis within the lacrimal sac. Gram-positive bacteria were identified in 73% (11/15), gram-negative bacteria in 13% (2/15), and mixed infection in 13% (2/15), respectively. Cases who had dacryocystorhinostomy as definitive treatment, either acutely (n = 3) or electively (n = 10) had full resolution. Transcutaneous drainage of the medial wall abscess in 10 patients helped resolve acute cellulitis. Four patients declined dacryocystorhinostomy after transcutaneous drainage; 2 had repeated dacryocystitis and orbital cellulitis, while 2 had no further infective episodes. One immunosuppressed patient had rapid progression to non-perception-of-light vision due to fungal invasion. Forty-six published cases reported up to 28% permanent loss of vision (perception-of-light and non-perception-of-light). Dacryoliths were discovered in 17% of published cases. Conclusions: Orbital cellulitis complicating dacryocystitis appears to be related to recurrent dacryocystitis and possibly the presence of dacryoliths. Immunosuppression is identified as a poor prognostic factor in this series. While transcutaneous drainage works well as a temporizing measure, dacryocystorhinostomy either done acutely or deferred until resolution of orbital cellulitis is required for definitive cure.

An amplitude analysis of B^{-}→D^{-}D^{0}K_{S}^{0} decays is performed using proton-proton collision data, corresponding to an integrated luminosity of 9  fb^{-1}, collected with the LHCb detector at center-of-mass energies of 7, 8, and 13 TeV. A resonant structure of spin-parity 0^{+} is observed in the D^{0}K_{S}^{0} invariant-mass spectrum with a significance of 5.3σ. The mass and width of the state, modeled with a Breit-Wigner line shape, are determined to be 2883±11±8  MeV/c^{2} and 87_{-47}^{+22}±17  MeV, respectively, where the first uncertainties are statistical and the second systematic. These properties and the quark content are consistent with those of the open-charm tetraquark candidate T_{cs0}^{*}(2870)^{0} observed previously in the D^{+}K^{-} final state of the B^{-}→D^{-}D^{+}K^{-} decay. This result confirms the existence of the T_{cs0}^{*}(2870)^{0} state in a new decay mode. The T_{cs1}^{*}(2900)^{0} state, reported in the B^{-}→D^{-}D^{+}K^{-} decay, is also searched for in the D^{0}K_{S}^{0} invariant-mass spectrum of the B^{-}→D^{-}D^{0}K_{S}^{0} decay, without finding evidence for it.

A study of Λ_{b}^{0} and Ξ_{b}^{0} decays to Λh^{+}h^{'-} (h^{(')}=π,K) is performed using pp collision data collected by the LHCb experiment during LHC Runs 1-2, corresponding to an integrated luminosity of 9  fb^{-1}. The branching fractions for these decays are measured using the Λ_{b}^{0}→Λ_{c}^{+}(→Λπ^{+})π^{-} decay as a control channel. The decays Λ_{b}^{0}→Λπ^{+}π^{-} and Ξ_{b}^{0}→ΛK^{-}π^{+} are observed for the first time. For decay modes with sufficient signal yields, CP asymmetries are measured in the full and localized regions of the final-state phase space. Evidence is found for CP violation in the Λ_{b}^{0}→ΛK^{+}K^{-} decay, interpreted as originating primarily from an asymmetric Λ_{b}^{0}→N^{*+}K^{-} decay amplitude. The measured CP asymmetries for other decays are compatible with zero.

The CP asymmetry and branching fraction of the Cabibbo-Kobayashi-Maskawa-suppressed decay B^{+}→J/ψπ^{+} are precisely measured relative to the favored decay B^{+}→J/ψK^{+} using a sample of proton-proton collision data corresponding to an integrated luminosity of 5.4  fb^{-1} recorded at a center-of-mass energy of 13 TeV during 2016-2018. The results of the CP asymmetry difference and branching fraction ratio are ΔA^{CP}≡A^{CP}(B^{+}→J/ψπ^{+})-A^{CP}(B^{+}→J/ψK^{+})=(1.29±0.49±0.08)×10^{-2}, R_{π/K}≡[B(B^{+}→J/ψπ^{+})/B(B^{+}→J/ψK^{+})]=(3.852±0.022±0.018)×10^{-2}, where the first uncertainties are statistical and the second are systematic. A combination with previous LHCb results based on data collected at 7 and 8 TeV in 2011 and 2012 yields ΔA^{CP}=(1.42±0.43±0.08)×10^{-2} and R_{π/K}=(3.846±0.018±0.018)×10^{-2}. The combined ΔA^{CP} value deviates from zero by 3.2 standard deviations, providing the first evidence for direct CP violation in the amplitudes of beauty decays to charmonium final states.

Objective: The purpose of this study was to provide Australian data on the clinical and radiological features and outcomes in patients with orbital plasmacytomas. Methods: Multicenter retrospective review of orbital plasmacytoma and orbital involvement in multiple myeloma (MM) from 2005 to 2022 in Australia. Results: Twenty-one participants were identified. The median age was 62 years (range 34-88 years), and 11 (52%) were females. Eighteen (84%) had a known diagnosis of MM prior to their orbital presentation, with all patients eventually being diagnosed with systemic MM. Thirteen (72%) were receiving active treatment for systemic myeloma on presentation, while 3 (17%) were in remission. All but 1 had unilateral orbital involvement (n = 20, 95%). Common presenting symptoms and signs were decreased visual acuity (n = 13, 62%), proptosis (n = 11, 52%), limited motility (n = 15, 71%), and optic neuropathy (n = 5, 24%). Radiologically, 15 (71%) involved the superotemporal orbit, 7 (33%) inferotemporal orbit, and 16 (76%) involved ≥1 extraocular muscle. Sixteen (76%) were biopsied and confirmed orbital plasmacytoma on histopathology. Treatment modalities included intravenous and oral steroids (n = 7, 33%), chemotherapy (n = 9, 43%), radiotherapy (n = 13, 62%), stem cell transplant (n = 3, 14%), and surgical debulking and decompression (n = 3, 14%). Mortality was high, with 15 (71%) having MM-related mortality. Conclusions: This is the largest cohort of Australian data on orbital plasmacytomas. Most patients have a diagnosis of systemic MM at presentation. It is crucial to recognize and treat these patients early due to a poor systemic prognosis.
