Efficacy of an eConsult service to cure hepatitis C in primary care

In 2016, an eConsult service was developed within a safety net health system to expand access to hepatitis C (HCV) treatment in the primary care setting. The eConsult system provides individualized treatment recommendations from specially trained primary care pharmacists and primary care physicians to primary care providers with less experience in the rapidly changing treatment of HCV. Since its launch, this service has had a large impact in expanding care to a largely homeless and low-income urban population within our health system. We now aim to evaluate its efficacy in curing HCV. In this retrospective cohort study, we describe rates of sustained virologic response 12 weeks after treatment completion (SVR12) for those who received primary care-based HCV treatment through the eConsult system with those who were treated in primary care independent of an eConsult from 2017 to 2019. We found there was no significant difference in the proportion of patients who achieved SVR12 between the two groups. Overall, >90% of patients who received treatment achieved SVR12. Approximately 40% of patients treated for HCV received an eConsult, suggesting utility of the eConsult in expanding access and coordinating treatment for patients within our network.     

Outcome of sentinel lymph node biopsy in breast cancer using dye alone: a single center review with a median follow-up of 5 years

Purpose

Various techniques are used for sentinel lymph node biopsy (SLNB) in breast cancer. While subareolar injection with dye alone is a relatively easy method, few studies have reported the outcome with a follow-up period. This study presents our results of SLNB using dye alone.

Methods

Between November 2002 and December 2010, 701 patients with breast cancer underwent SLNB using subareolar injection of indocyanine green or indigo carmine. Sentinel lymph node (SLN)-negative patients were followed without axillary lymph node dissection (ALND).

Results

SLNs were detected in 654 of 701 patients (93.3 %), and the rate increased to 98.1 % over the course of the study. The mean number of SLNs removed was 1.5. There was no significant difference in the detection rate between two dyes. No adverse events resulted from the injection of dyes. Of the 654 patients, 136 (20.8 %) had SLN metastasis. Five hundred patients were followed without ALND. Thirty-six patients experienced disease relapse during a median follow-up of 60 months. Thirteen patients (2.6 %) had regional lymph node relapse, and eight of them could undergo salvage lymph node dissection. The 5-year disease-free and overall survival rates were 92.4 and 96.1 %, respectively.

Conclusion

SLNB using subareolar injection with dye alone was safe and feasible even after a long follow-up.     

Relationship between depression and risk of malnutrition among community-dwelling young-old and old-old elderly people

Objectives: This study explores the association between nutritional status and depression among healthy community-dwelling young-old (aged 65–74) and old-old elderly (aged 75 and older).

Method: A cross-sectional design was implemented. A total of 274 community-dwelling older individuals (142 young-old; 132 old-old) were assessed using the Geriatric Depression Scale (GDS), Mini-Nutritional Assessment Short-Form (MNA-SF) and Life-Space Assessment. Logistic regression analysis was used to determine if depression was independently associated with risk of malnutrition, stratified by age (young-old vs. old-old).

Results: In the logistic regression model for young-old, being at risk of malnutrition (MNA-SF (≦11) was strongly associated with depression (GDS (≧5;) (likelihood ratio ν?=?6.26; 95% confidence interval [CI]: 1.91–20.49). In contrast, in the old-old group, the model was not statistically significant.

Conclusion: Depression and nutritional status were strongly correlated in young-old but not in old-old community-dwelling elderly. This study reveals that not only the factors correlated with but also the symptoms of depression may vary among different age stratifications of the elderly.     

Acute pulmonary edema associated with naphazoline ingestion

In published reports of naphazoline ingestion, clinical effects are hypertension, bradycardia, pallor, diaphoresis, and respiratory distress. We report three cases of acute pulmonary edema after the intentional ingestion of naphazoline-containing antiseptic first aid liquid. These cases presented with altered mental status, hypertension, bradycardia, and diaphoresis. Chest x-ray on admission revealed acute pulmonary edema. Two cases required mechanical ventilation. All of these clinical effects resolved within 24 hours and the patients were discharged with no sequelae. Since naphazoline stimulates the peripheral alpha-2 adrenergic receptor, we speculate that intense vasoconstriction may have elevated cardiac afterload and left atrial-ventricular blood volume and caused acute pulmonary edema.     

Laparoscopic microwave coagulation therapy for hepatocellular carcinoma

BACKGROUND AND STUDY AIMS: Several different effective forms of treatment are available, singly or in combination, for patients with hepatocellular carcinoma (HCC). These include surgical resection, transcatheter arterial embolization, percutaneous ethanol injection, and percutaneous microwave coagulation therapy. In this study, we carried out laparoscopic microwave coagulation therapy (LMCT), using laparoscopic microwave electrodes to treat HCC. PATIENTS AND METHODS: Under local anesthesia, 24 patients with HCCs located on or near the liver surface underwent LMCT under direct laparoscopic vision, with ultrasound guidance. LMCT was performed using microwave electrodes with tips ranging from 15-45 mm in length, and the effectiveness of the treatment was confirmed using contrast-enhanced computed tomography (CT) within two weeks of the LMCT procedure. RESULTS: The mean longest axis of the 26 HCC nodules in 24 patients was 20 mm, and that of the coagulated areas including the nodules was 40 mm, with additional therapy being required in two patients. Complete efficacy of the treatment was observed in 21 patients (87.5%), but local recurrences were seen in three of them one year after LMCT. The three-year survival rate was 92%, but the number of patients included in the study was small. Hemostasis was complete, but mild pneumothorax occurred in three patients. CONCLUSIONS: LMCT under local anesthesia is a minimally invasive and effective therapy when carried out on a single occasion to treat HCCs located near the liver surface, and it can be safely performed under direct visual guidance.
