Gossypiboma: its laparoscopic diagnosis and removal

Retained surgical sponges are an under-reported occurrence. Clinical presentation may be acute or subacute, and may follow months or even years after surgery. We report on a case in which laparoscopy was used to both diagnose and treat a retained surgical sponge.     

Symptoms of depression and anxiety (MHI) following acute medical/surgical hospitalization and post-discharge psychiatric diagnoses (DSM) in 839 geriatric US veterans

OBJECTIVE: We addressed the relatively unexplored use of screening scores measuring symptoms of depression and/or anxiety to aid in identifying patients at increased risk for post-discharge DSM-IV Axis I diagnoses. We were unable to find such studies in the literature. METHOD: Elderly veterans without recent psychiatric diagnoses were screened for depression and anxiety symptoms upon admission to acute medical/surgical units using the Mental Health Inventory (MHI). Following discharge, those who had exceeded cut-off scores and had been randomized to UPBEAT Care (Unified Psychogeriatric Biopsychosocial Evaluation and Treatment, a clinical demonstration project) were evaluated for DSM diagnoses. We report on 839 patients, mostly male (96.3%; mean age 69.6 +/- 6.7 years), comparing three groups, i.e. those meeting screening criteria for symptoms of (i) depression only; (ii) anxiety only; and (iii) both depression and anxiety. RESULTS: Despite absence of recent psychiatric history, 58.6% of the 839 patients received a DSM diagnosis post-discharge (21.8% adjustment; 15.4% anxiety; 7.5% mood; and 14.0% other disorders). Patients meeting screening criteria for both depression and anxiety symptoms received a DSM diagnosis more frequently than those meeting criteria for anxiety symptoms only (61.9% vs 49.0%, p = 0.017), but did not differ significantly from those meeting criteria for depressive symptoms only (61.9% vs 56.8%, p = 0.174). Although exceeding the MHI screening cut-off scores for depression, anxiety, or both helped to identify patients with a post-discharge DSM diagnosis, the actual MHI screening scores failed to do so. CONCLUSION: Screening hospitalized medical/surgical patients for symptoms of depression, anxiety, and particularly for the combination thereof, may help identify those with increased risk of subsequent DSM diagnoses, including adjustment disorder.     

Intraocular ciprofloxacin levels after oral administration in silicone oil-filled eyes

PURPOSE: To evaluate penetration of oral ciprofloxacin in the retro-silicone oil space fluid (RSOF) in silicone oil (SO)-filled eyes. METHODS: One dose of 750 mg ciprofloxacin was given to two groups of five patients with vitrectomized eyes with SO endotamponade, 4 hours (group I) and 8 hours (group II) before SO removal. In 10 vitrectomized eyes with SO endotamponade (group III) and another 10 patients scheduled for vitrectomy for the first time (group IV), two 750-mg doses every 12 hours, with the last dose 12 hours before surgery, were given. Blood samples were taken at the time of collection of RSOF samples in groups I, II, and III and of the vitreous in group IV. All samples were assayed for ciprofloxacin by high-performance liquid chromatography. RESULTS: The mean drug concentration in the RSOF was 0.34 +/- 0.09, 0.37 +/- 0.04, 0.84 +/- 0.29, and 0.44 +/- 0.11 micro g/mL in groups I, II, III, and IV respectively. The mean serum concentration was 1.29 +/- 0.63, 1.08 +/- 0.14, 1.93 +/- 0.84, and 1.34 +/- 0.55 micro g/mL in groups I, II, III, and IV respectively with no statistically significant difference between groups III and IV (P = 0.081). CONCLUSIONS: Antibiotic levels in the RSOF in SO-filled eyes after oral administration of ciprofloxacin in two 750-mg doses exceeded the minimal inhibitory concentration for 90% of isolates (MIC(90)) for most bacterial species and was higher than levels reached in the vitreous in nonvitrectomized eyes (P = 0.001).

Results of chronic Achilles tendinopathy surgery on elite and nonelite track athletes

Twenty-seven track athletes/runners with chronic Achilles tendinopathy underwent a retrospective review of 37 surgical Achilles procedures performed between 1990 and 1999. There were 22 males and 5 females. Average age of the group was 36.6 years (range, 16-75 years). The mean "return to activity" (RTA) was 10.6 +/- 6.3 weeks. For elite athletes, RTA was 7.9 = 4.8 weeks. For nonelite athletes, RTA was 15.0 +/- 6.2 weeks, and was statistically higher (p = .003). There was no significant difference between males' and females' RTA. Average follow-up for the group was 4.7 years (range, 1-10 years). Runners on average ran more than 60 miles a week. There were 14 elite and 13 nonelite athletes, including four Olympians, five sub-4-minute milers, and four National Champions. Return to competition and "100%" were 25.0 and 25.4 weeks, respectively, for the elite group. Return to competition for the nonelite group was 27.0 +/- 11.0 weeks. Eighteen patients underwent peritenolysis with a mean RTA of 7.7 weeks. Of this group, four patients with concomitant bony procedures had significantly slower RTA as opposed to the 14 patients who had peritenolysis only (mean, 4.5 weeks). Four patients had Achilles debridement for mucoid degeneration, and a mean RTA of 12.8 weeks. Eleven patients had Haglund-type procedure (retrocalcaneal exostectomy) had a mean RTA of 15.1 weeks. Six Achilles tendocalcinosis repair patients had a mean RTA of 12.0 weeks. There were three reoperations, two of which were performed by the author. Using the Testa Achilles tendon surgery rating scale, this group of patients had 34 "excellent" and 3 "good" results. The patients who underwent a reoperation were able to achieve "good" or better results.     

The effect of foot orthoses on patellofemoral pain syndrome

In a retrospective review of 102 patients treated for chondromalacia pa-tellae and patellofemoral pain syndrome/retropatellar dysplasia (PFPS/RPD), the effectiveness of semiflexible foot orthoses was investigated. The combined disorders were diagnosed in 89.3% of the patients. Subjects were 46 women and 54 men, aged 12 to 87 years (mean, 37.9 years; SD, 15.9), who exhibited excessive forefoot varus or rearfoot varus. The initial screening and clinical diagnosis were based on an examination by an orthopedist. Particular attention was directed to patellar crepitation, patellofemoral malalignment, Q-angle measurements, limitation of range of motion, and knee effusion. Patients were evaluated for the onset and duration of patellofemoral pain and degree of knee joint disease. Semiflexible orthoses for each subject were fabricated, based on a clinical lower extremity biomechanical examination. At their follow-up visit, 76.5% were improved and 2% were asymptomatic, showing a significant decrease in the level of pain with orthoses intervention (chi-square P <.001). Although multiple treatment modalities are used for these patients, the results suggest that the use of semiflexible orthoses is significant in reducing symptoms of PFPS/RPD.     

Analysis of Patterns and Treatment Strategies for Mandibular Condyle Fractures: Review of 175 Condyle Fractures with Review of Literature

This study aims to evaluate incidence, patterns and epidemiology of mandibular condylar fractures (MCF) to propose a treatment strategy for managing MCF and analyze the factors which influence the outcome. One hundred and seventy-five MCF’s were evaluated over a four year period and their pattern was recorded in terms of displacement, level of fracture, age of incidence and dental occlusion. Of the 2,718 facial bone fractures, MCF incidence was the third most common at 18.39 %. Of 175 MCF 58.8 % were unilateral and 41.12 % were bilateral. 67 % of bilateral fractures and 43.8 % of unilateral fractures were associated with midline symphysis and contralateral parasymphysis fractures respectively. Most of the MCF was seen in the age group of above 16 years and 50 % of them were at subcondylar level (below the neck of the condyle). Majority of MCF sustained due to inter personal violence were undisplaced (72.7 %) and contrary to this majority of MCF sustained during road traffic accident were displaced. 62.9 % of total fractures required open reduction and rigid fixation and 37.1 % were managed with closed reduction. 80 % of MCF managed with closed reduction were in the age group of below 16 years. From this study it can be concluded that the treatment algorithm proposed for managing MCF is reliable and easy to adopt. We observed that absolute indication for open reduction of MCF is inability to achieve satisfactory occlusion by closed method and absolute contraindication for open reduction is condylar head fracture irrespective of the age of the patient.     

Resveratrol inhibits tumor growth of human neuroblastoma and mediates apoptosis by directly targeting mitochondria.

PURPOSE: Neuroblastoma is an aggressive childhood disease of the sympathetic nervous system. Treatments are often ineffective and have serious side effects. Because resveratrol, a natural plant product, has been reported to have limited toxicity at chemotherapeutic levels, we investigated its efficacy in the treatment of neuroblastoma as well as its underlying mechanism of action. EXPERIMENTAL DESIGN: Resveratrol was tested in mouse xenograft models of human neuroblastoma and in vitro using human cell lines. RESULTS: Resveratrol inhibited the outgrowth of tumors by as much as 80%. The bioavailability of the drug in serum was in the low micromolar range (2-10 micromol/L) and no accumulation was observed in tumor tissue. When resveratrol levels were increased by peritumor injection, rapid tumor regression occurred. Resveratrol decreased tumor cell viability in vitro by 75% to 90%, resulting from an inhibition of cell proliferation and an induction of apoptosis. Loss of mitochondrial membrane potential was an early response to resveratrol. In addition, resveratrol treatment of isolated mitochondria also led to depolarization, suggesting that the drug may target mitochondria directly. Following depolarization, resveratrol caused the release of cytochrome c and Smac/Diablo from the mitochondria and subsequently the activation of caspase-9 (4- to 8-fold) and caspase-3 (4- to 6-fold). CONCLUSIONS: These studies indicate that, despite low bioavailability, resveratrol is effective at inhibiting tumor growth. Elevated levels of resveratrol enhance its antitumor potency leading to tumor regression, associated with widespread tumor cell death, the underlying mechanism of which involves the direct activation of the mitochondrial intrinsic apoptotic pathway.
