Injury and illness epidemiology in professional Asian football: lower general incidence and burden but higher ACL and hamstring injury burden compared with Europe.

BACKGROUND: While football injury and illness epidemiology surveillance at professional club level in Europe is available, epidemiological data from other continents are lacking. PURPOSE: Investigating injury and illness epidemiology in professional Asian football. STUDY DESIGN: Descriptive prospective study. METHODS: Professional teams from the Asian Football Confederation (AFC) league were followed prospectively for three consecutive AFC seasons (2017 through 2019, 13 teams per season, 322 team months). Time-loss injuries and illnesses in addition to individual match and training exposure were recorded using standardised digital tools in accordance with international consensus procedures. RESULTS: In total, 232 665 hours of exposure (88.6% training and 11.4% matches) and 1159 injuries were recorded; 496 (42.8%) occurred during matches, 610 (52.6%) during training; 32 (2.8%) were reported as 'not applicable' and for 21 injuries (1.8%) information was missing. Injury incidence was significantly greater during match play (19.2±8.6 injuries per 1000 hours) than training (2.8±1.4, p<0.0001), resulting in a low overall incidence of 5.1±2.2.The injury burden for match injuries was greater than from training injuries (456±336 days per 1000 hours vs 54±34 days, p<0.0001). The two specific injuries causing the greatest burden were complete ACL ruptures (0.14 injuries (95% CI 0.9 to 0.19) and 29.8 days lost (29.1 to 30.5) per 1000 hours) and hamstring strains (0.86 injuries (0.74 to 0.99) and 17.5 days (17.0 to 18.1) lost per 1000 hours).Reinjuries constituted 9.9% of all injuries. Index injuries caused 22.6±40.8 days of absence compared with 25.1±39 for reinjuries (p=0.62). The 175 illnesses recorded resulted in 1.4±2.9 days of time loss per team per month. CONCLUSION: Professional Asian football is characterised by an overall injury incidence similar to that reported from Europe, but with a high rate of ACL ruptures and hamstring injury, warranting further investigations.

Injury and illness epidemiology in soccer - effects of global geographical differences - a call for standardized and consistent research studies.

Soccer is the most popular sport in the world. While injuries and illnesses can affect the players' health and performance, they can also have a major economic impact on teams. Moreover, several studies have shown the favourable association between higher player availability and team success. Therefore, injury prevention could directly impact clubs' financial balance and teams' performance via increased player availability. To be able to develop effective methods of injury prevention, it is vital to first determine the scope and the degree of the problem: the mechanisms and types of injuries, their frequency and severity, etc. According to the most widely known prevention model, systematic injury surveillance is the first and most fundamental step towards injury prevention. Since epidemiological studies have shown that injuries and illnesses in soccer players differ from region to region, it is important to establish a specific injuries and illness database in order to guide specific preventive actions. Since Asia is the largest continent, with the highest number of soccer players, and in the light of the long-term research on injuries performed in UEFA clubs, the authors of the present article present the AFC surveillance. Some methodological issues related to this prospective design study are discussed. The definition of injury and illness and the methods to track players' exposure are described along with the potential challenges related to such a vast scale study. This article is also a call for action to have consistent and standardized epidemiological studies on soccer injuries and illnesses, with the aim to improve their prevention.

Demographic profile, prevalence, pattern, and risk factors for retinal vein occlusion in Liberia: A retrospective study.

PURPOSE: This study aims to describe the demographic profile, prevalence, pattern, and risk factors for retinal vein occlusion (RVO) in patients over 40 years of age presenting to the Liberia Eye Centre, John F Kennedy Memorial Medical Centre, Monrovia, Liberia. SUBJECTS AND METHODS: A retrospective study was conducted on patients presenting to Liberia Eye Centre from July 2017 to February 2021. A total of 17506 new patients were examined during this period out of which 10813 patients were over 40 years of age. Data were collected from the electronic medical record system database. The variables in the collected data included age, gender, location, laterality of eye affected, uncorrected visual acuity, best-corrected visual acuity, intraocular pressure, ocular diagnosis, systemic risk factors, and associated complications. RESULTS: Of the 10813 patients, RVO was found in 111 patients with an overall prevalence rate of 1.03% (95% confidence interval 0.80-1.2). Central RVO (CRVO) was more common than branch RVO (BRVO) in the defined population with similar proportions of both genders. The mean age for any RVO was 64.45 ± 12.27 standard deviation (SD) years (P = 0.734). Majority of the cases of RVO were from Lofa (n = 20; 18%). Fifty-five (61.1%) patients had hypertension, 5 (5.6%) had diabetes mellitus, and 6 (6.7%) had dyslipidemia. More than one systemic risk factor was present in 24 (26.7%) patients. However, none of the systemic risk factors were statistically significant. Visual acuity was most affected in patients with CRVO, with a visual acuity of <3/60 in 45 (63.4%) patients compared to 12 (30.0%) in BRVO patients. Glaucoma was present in 34 (30.6%) patients. The most common ocular complication was macular edema (n = 62, 55.8%) followed by vitreous hemorrhage (n = 8, 7.2%). CONCLUSIONS: RVO was detected in 1.03% of the study population over the age of 40 years in Liberia, CRVO being more common than BRVO. The clinical presentation of RVO in the Liberian population for the first time provides insight into the burden of the disease and opportunity for further research.

Clear cell hidradenocarcinoma of the eyelid: a case report with a review of the literature.

Clear cell hidradenocarcinomas are extremely rare neoplasms, with very few well-documented cases reported in the literature. The most common sites are the head and neck regions. These tumors are histologically malignant but are not always aggressive. They are known for recurrence and may metastasize widely. Treatment is wide local resection. We report on a case of clear cell hidradenocarcinoma occurring over the eyelid together with a review of the literature.

Postoperative Euglycemic Ketoacidosis in Type 2 Diabetes Associated with Sodium-Glucose Cotransporter 2 Inhibitor: Insights Into Pathogenesis and Management Strategy.

Euglycemic diabetic ketoacidosis (eu-DKA) is an uncommon and serious adverse event associated with the use of sodium-glucose cotransporter (SGLT-2) inhibitors. It is a state of increased anion gap metabolic acidosis with ketosis but in the setting of normal serum glucose levels. Diagnosis of this serious entity could easily be missed given the non-specific symptoms and the normal glucose measurements. This ketogenic state can be triggered by various stressors including infection, surgery, myocardial infarctions, omission of insulin dosage, as well as low carbohydrate diet. In this report, we present a case of eu-DKA in a 68-year-old woman with type 2 diabetes that occurred in the postoperative period of glaucoma surgery. She was started shortly before surgery on SGLT-2 inhibitor (ertugliflozin). While the diagnosis was initially missed, it was subsequently confirmed when she presented with reduced appetite, generalized fatigue, and constipation. Ertugliflozin was discontinued, and she was successfully treated with conservative management and without insulin drip. This case highlights the need to consider the diagnosis of eu-DKA in patients treated with SGLT-2 inhibitors since the diagnosis could easily be missed especially in the postoperative period with the non-characteristic symptomatology and normoglycemia.

Efficacy and Safety Outcomes of Cataract Surgery in Survivors of Ebola Virus Disease: 12-Month Results From the PREVAIL VII Study.

Purpose: In survivors of Ebola virus disease (EVD), intraocular viral persistence raises questions about the timing and safety of cataract surgery. To the best of our knowledge, this is the first controlled study evaluating Ebola virus persistence and cataract surgery safety and outcomes in EVD survivors. Methods: Seropositive EVD survivors and seronegative controls with vision worse than 20/40 from cataract and without active intraocular inflammation were enrolled. Aqueous humor from survivors was tested with reverse transcription-polymerase chain reaction for Ebola viral RNA. Participants underwent manual small-incision cataract surgery and 1 year of follow-up examinations. Results: Twenty-two eyes of 22 survivors and 12 eyes of eight controls underwent cataract surgery. All of the aqueous samples tested negative for Ebola viral RNA. Median visual acuity improved from 20/200 at baseline to 20/25 at 1 year in survivors and from count fingers to 20/50 in controls (overall, P < 0.001; between groups, P = 0.07). After a 1-month course of topical corticosteroids, 55% of survivors and 67% of controls demonstrated at least 1+ anterior chamber cell. Twelve months after surgery, optical coherence tomography revealed a median increase in macular central subfield thickness of 42 µm compared with baseline (overall, P = 0.029; between groups, P = 0.995). Conclusions: EVD survivors and controls demonstrated significant visual improvement from cataract surgery. The persistence of intraocular inflammation highlights the importance of follow-up. The absence of detectable intraocular Ebola viral RNA provides guidance regarding the safety of eye surgery in Ebola survivors. Translational Relevance: These findings demonstrate the safety and efficacy of cataract surgery in Ebola survivors and will inform ocular surgery guidelines in this population.

Factors associated with visual outcomes after cataract surgery: A cross-sectional or retrospective study in Liberia.

OBJECTIVE: To report the initial outcomes and associated risk factors for poor outcome of cataract surgery performed in Liberia. METHODS AND ANALYSIS: LV Prasad Eye Institute (LVPEI), Hyderabad, started providing eye care in Liberia since July 2017. Electronic Medical Records of 573 patients operated for age-related cataract from July 2017 to January 2019 were reviewed. One eye per patient was included for analysis. All patients underwent either phacoemulsification or manual small incision cataract surgery (MSICS). Pre and postoperative uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA) were recorded at one day, 1-3 weeks and 4-11 weeks. Main outcome measure was BCVA at 4-11 weeks; Intraoperative complications and preoperative ocular comorbidities (POC) were noted. BCVA less than 6/12 was classified as visual impairment (VI). Risk factor for VI was analysed using the logistic regression model. RESULTS: Of the 573 patients, 288 were males and 285 were females (49.7%). Mean age was 65.9±10.9 years; 14.3% had POC. The surgical technique was mainly MSICS (94.59%, n = 542). At 4-11 weeks, good outcome of 6/12 or better was noted in 38.55% (UCVA) and 82.54% (BCVA). Visual acuity (VA) of 6/18 or better as UCVA and BCVA was noted in 63.5% and 88% eyes respectively. Poor outcome of less than 6/60 was noted as UCVA (11.11%) and BCVA (5.22%). Multivariable analysis showed poor visual outcomes significantly higher in patients with POC (odds ratio 3.28; 95% CI: 1.70, 6.34). CONCLUSION: The cataract surgical outcomes in Liberia were good; with ocular comorbidities as the only risk factor.

Affection of immune zones in leprosy: a clinico-epidemiological study.

The study was undertaken to evaluate the prevalence of involvement of immune zones in leprosy and to assess the clinico-epidemiological characteristics of the disease in patients presenting with immune zone involvement. 200 leprosy cases were included in this study and detailed history, clinical examination, slit-skin smears and skin biopsies were carried out on all patients. Those cases presenting with immune zone involvement were further evaluated for clinical and epidemiological characteristics of disease process. Immune zone involvement was detected in 7% of cases with male preponderance in the study. Majority of patients (85.5%) had borderline tuberculoid leprosy and midline of back was the commonest site of involvement (50% of cases). Morphologically, macular lesions were the commonest presentation (85.68%) of immune zone involvement. The study heightens the clinical awareness of the possibility of occurrence of leprous lesions on uncommon and unusual sites, which should be termed as relatively immune, rather than absolutely immune zones of leprosy.

CD-3 positive extranodal T-cell lymphoma of nasal type with skin involvement.

A 40-year-old previously healthy lady presented with nasal obstruction and localized plaques over the right arm. She developed complete nasal obstruction due to a mass in the right nasal cavity and skin lesions that ulcerated to present as ecthyma gangrenosum like lesions. Patient's condition deteriorated fast and she developed icterus with fatal outcome within 4 weeks of developing skin lesions. Nasal and skin biopsy revealed angiocentric T-cell lymphoma, which on immuno-phenotyping revealed CD-3 positive; and CD-20, CD-30, ALK and EMA negativity. She was seronegative for HIV. Final diagnosis of CD-3 positive extranodal T-cell lymphoma of nasal type was made. Extranodal T-cell lymphomas are very aggressive NHLs with poor prognosis. Prognosis depends on histology, stage of the disease and sites of involvement. NK/T cell lymphoma of nasal type is common with EBV association. Skin involvement is rare and is also an indicator of poor prognosis.

Stigma experience in skin disorders: an Indian perspective.

Dermatologic disorders generally have a major impact on patients' daily activities, psychologic and emotional state, and social relationships. The intensity of impact of skin disease on an individual person is extremely variable, however, and depends on natural history of the disorder; the patient's demographic characteristics, personality, character, and value; the patient's life situation; and the attitudes of society. Social stigma toward dermatologic disorders in the Indian society is quite widespread, especially toward leprosy. Dermatologists are expected to consider quality of life issues along with social aspects, nature of disorder, efficacy, and tolerability of various therapeutic options to optimize relief and comfort to their patient.

Nail changes and disorders among the elderly.

Nail disorders are frequent among the geriatric population. This is due in part to the impaired circulation and in particular, susceptibility of the senile nail to fungal infections, faulty biomechanics, neoplasms, concurrent dermatological or systemic diseases, and related treatments. With aging, the rate of growth, color, contour, surface, thickness, chemical composition and histology of the nail unit change. Age associated disorders include brittle nails, trachyonychia, onychauxis, pachyonychia, onychogryphosis, onychophosis, onychoclavus, onychocryptosis, onycholysis, infections, infestations, splinter hemorrhages, subungual hematoma, subungual exostosis and malignancies. Awareness of the symptoms, signs and treatment options for these changes and disorders will enable us to assess and manage the conditions involving the nails of this large and growing segment of the population in a better way.

A comparative evaluation of skin and nerve histopathology in single skin lesion leprosy.

BACKGROUND: In spite of leprosy being a disease of nerves, ROM therapy for single skin lesion leprosy was based on clinical trials without much evidence-based studies of nerve pathology. The present study was undertaken to compare the histology of skin and nerve in single skin lesion leprosy, and to assess the scientific rationale and justification of single dose ROM therapy. METHODS: Twenty-seven untreated patients with single skin lesion without significantly thickened peripheral nerves were selected. Skin and nearby pure cutaneous nerve biopsies were studied under both H&E and Fite's stain. RESULTS: All the skin biopsies were negative for AFB and clinico-pathological correlation was positive in 51.85% of skin biopsy specimens. Histopathological diagnosis of leprosy was evident in 55.5% of clinically normal looking nerves, with AFB positivity in 29.6% of nerve biopsy specimens. Correlation between clinical diagnosis and nerve histopathology was poor (26%). CONCLUSIONS: Single skin lesion without thickened peripheral nerves as criteria for single dose ROM therapy is not logical, since the histological diagnosis of leprosy in normal looking nerves with presence of AFB is revealed in this study. Pure cutaneous nerve biopsy is a simple outpatient procedure, without complications. This study emphasizes the need to consider nerve pathology as an important tool for further therapeutic recommendations, than just clinical trials and skin pathology alone. Though single dose ROM therapy has been withdrawn recently, the principle holds good for any future therapeutic recommendations.

Nails in systemic disease.

Nail abnormalities secondary to systemic disease could be classified as nail abnormalities associated with systemic disease, disease of specific organ system or associated with syndromes and genodermatoses. Because nail findings are easily observable and yield valuable information, careful examination of nails could be an important diagnostic tool for a dermatologist. A brief review of the common and not so common nail changes in systemic illness is presented.

Pharmacovigilance: scope for a dermatologist.

Pharmacovigilance is defined as the science of detection, assessment, and prevention of adverse drug reactions in humans. Under-reporting of drug reactions is the major problem and has various reasons. The WHO has initiated the program of reporting all adverse drug reactions now co-ordinated by the Uppsala Monitoring Centre in Uppsala, Sweden, with oversight by an international board. This article presents in brief the relevance, functioning, importance, and the procedure of reporting adverse drug reactions. Dermatologists have the greatest opportunity in reporting various reactions that can happen as they come across majority of these drug reactions, prescribed by all sectors of the health system.

Cardiovascular comorbiditiy in psoriasis.

The chronic inflammatory nature of psoriasis is also thought to predispose patients to other diseases with an inflammatory component, the most notable being cardiovascular and metabolic (cardiometabolite) disorders. This concept is supported by studies showing that psoriasis is associated with cardiovascular risk factors like diabetes, obesity, hypertension, dyslipidemia, smoking and diseases including MI. Given the increased prevalence of cardiovascular co morbidities in patients, dermatologists treating psoriasis need to approach the disease as a potentially multisystem disorder and must alert these patients to the potentially negative effects of their disease.
