Aspergillus Iris Granuloma: A Case Report with Review of Literature

We report the case of a 25-year-old male patient who presented with complaints of redness, photophobia, and decreased vision in the right eye of a week's duration. Slit-lamp biomicroscopic examination revealed a cream-colored, irregular elevated inferior iris mass, extending on to the anterior lens surface. Differential diagnoses of a fungal granuloma, a medulloepithelioma, and an amelanotic melanoma were considered. An excisional biopsy of the mass was performed through a superior clear corneal incision. Polymerase chain reaction analysis of the aqueous humor showed a positive pan fungal genome. Histopathology of the biopsied mass showed a giant cell granuloma with surrounding numerous branching, septate hyphae. Culture growth revealed Aspergillus fumigatus We report this case because of the rarity of Aspergillus iris granuloma as a primary presentation of endogenous Aspergillosis and review the relevant literature. Absence of a significant systemic history compounded the diagnostic dilemma in our patient. Definitive differentiation of this rare entity from a foreign body, amelanotic melanoma, and other inflammatory conditions such as sarcoidosis and tuberculosis, may be possible only on microbiological and histo-pathological evaluation.     

Primary Hemiarthroplasty for Proximal Humeral Fractures in the Elderly: Long-Term Functional Outcome and Social Implications

Abstract Background: Primary shoulder hemiarthroplasty is an established treatment modality for complex fractures of the proximal humerus. Long-term functional outcome is often disappointing. However, little is known about social implications particularly in the elderly. Methods: A single-institution case series of consecutive geriatric patients (age > 70 years) treated with shoulder hemiarthroplasty for complex fractures of the proximal humerus between 1994 and 1997 was analysed. Postoperative morbidity, long-term function, radiological outcome and social implications were evaluated. Results: Seventy-seven patients fulfilled the study criteria. Median age at the time of operation was 80 years (range 70–93 years). Systemic and local postoperative complications were observed in 8% including 2 patients (3%) with revision surgery. Postoperative mortality was 1%. Forty-eight patients (62%) were available for follow-up (median 49 months, range 25–80 months), 22 (29%) died from causes unrelated to hemiarthroplasty before follow-up and 7 patients (9%) did not attend follow-up examination. Median Constant-Murley score was 41 points (range 17–77 points). Long-term results concerning pain were satisfying. The Oxford shoulder score ranged from 14 to 40 (median 30). Forty-one patients (85%) still lived in their original environment and managed their daily life independently despite poor shoulder function. Four patients (8%) lived in a retirement home and 3 (6%) in a nursery home. Eighty percent of our patients were still able to use public transportation, do the daily shopping and wash their whole body by themselves. Conclusion: Most patients managed their daily life independently despite poor shoulder function.

腹腔镜胆囊切除术不同压力CO2气腹对气腹存留时限及肩部疼痛的影响

目的 探讨腹腔镜胆囊切除术(laparoscopic cholecystectomy,LC)不同压力CO2气腹对气腹存留时限及肩部疼痛的影响,探讨LC术后气腹存留时限的影响因素及肩部疼痛的原因.方法 2002年4～10月连续观察69例LC,随机分为A、B、C 3组,每组23例.气腹压力设定A组10mm Hg,B组12mm Hg,C组14mm Hg.对69例LC术后进行连续胸部X线平片观察膈下游离气体,测量术后24h两侧膈下游离气体的长、高并计算残气量.采用视觉模拟评分(vision analogue score,VAS)观察3组术后1、3、6、12、24、48、72、96、120h肩部疼痛程度.结果 LC后气腹存留时限为(1.8±1.1)d,男女组气腹存留时限分别为(1.8±1.1)d和(1.7±1.0)d,2组比较无显著意义(H=0.013,P=0.911).3组术后24h膈下残气量及术后气腹存留时限差异无显著性(P＞0.05).逐步回归分析示lg(气腹存留时限)与术后24h膈下残气量呈正相关(r=0.616,P=0.006),与气腹时间呈负相关(r=-0.228,P=0.014),与年龄、体重、身高、手术时间及所用气体量无相关性.术后26例出现肩部疼痛,随着A、B、C 3组气腹压力的增高,发生肩部疼痛患者的VAS评分明显增高(F=9.635, P=0.000),术后24h肩部疼痛VAS评分与术后24 h右侧膈下残气量呈正相关(r=0.333,P=0.005),与气腹存留时限呈正相关(r=0.296,P=0.014).结论 LC术毕尽量将腹腔内CO2气体排净可缩短术后残气吸收时间.不同压力CO2气腹对LC术后残余的CO2气体量及气腹存留时限无明显影响.LC后肩部疼痛程度随气腹压增高有明显加重趋势,人工气腹引起膈肌的张力可能是造成肩部疼痛的重要原因.     

Predictors of oral health quality of life in older adults

There is limited information regarding oral health status and other predictors of oral health‐related quality of life. An association between oral health status and perceived oral health‐related quality of life (OHQOL) might help clinicians motivate patients to prevent oral diseases and improve the outcome of some dental public health programs. This study evaluated the relationship between older persons' OHQOL and their functional dentition, caries, periodontal status, chronic diseases, and some demographic characteristics. A group of 733 low‐income elders (mean age 72.7 ISD=4.71, 55.6% women, 55.1% members of ethnic minority groups in the U.S. and Canada) enrolled in the TEETH clinical trial were interviewed and examined as part of their fifth annual visit for the trial. OHQOL was measured by the Geriatric Oral Health Assessment Index (GOHAI); oral health and occlusal status by clinical exams and the Eichner Index; and demographics via interviews. Elders who completed the four‐year assessment had an average of 21.5 teeth (SD=6.9). with 8.5 occluding pairs (SD=4.6), and 32% with occlusal contacts in all four occluding zones. Stepwise multiple regressions were conducted to predict total GOHAI and its subscores (Physical, Social, and Worry). Functional dentition was a less significant predictor than ethnicity and being foreign‐bom. These variables, together with gender, years since immigrating, number of carious roots, and periodontal status, could predict 32% of the variance in total GOHAI, 24% in Physical, 27% in Social, and 21 % in the Worry subscales. These findings suggest that functional dentition and caries influence older adults' OHQOL, but that ethnicity and immigrant status play a larger role.
