Effect of simvastatin on high density lipoprotein subfractions and apolipoproteins in Type IIa hypercholesterolemia

Summary Changes in plasma concentrations of high density lipoproteins (HDL) and triglycerides may partly explain the ability of cholesterol-lowering drugs to decrease the incidence of coronary heart disease. We measured the response of fasting plasma lipids, lipoproteins, and apolipoproteins in 46 subjects with Type IIa hypercholesterolemia treated with simvastatin for 3 months. The initial dose of simvastatin (10 mg/day) was subsequently increased up to 40 mg/day if the plasma cholesterol concentration had not fallen below 5.2 mmol/l. Plasma concentrations of HDL cholesterol and of the apolipoproteins AI and AII were increased by simvastatin. The increase in HDL cholesterol (9%) was due to increases in both subfractions (HDL₂ 17%; HDL₃ 7%), changes that would be consistent with a beneficial effect on cardiovascular risk. Simvastatin decreased plasma triglyceride concentrations by 25%. Plasma total cholesterol concentrations fell by 35% after 3 months of treatment; this fall was proportional to the initial concentration and was due almost entirely to a 45% fall in low density lipoprotein cholesterol. In contrast, plasma concentrations of lipoprotein Lp(a) were not affected by simvastatin.     

Sleep changes during prophylactic treatment of migraine

Aims:

To assess sleep quality in patients with primary headaches before and after prophylactic treatment using a validated sleep-screening instrument.

Materials and Methods:

A total of 147 patients, including 63 tension type headache (TTH) and 84 migraine patients were included. Patients were examined in terms of frequency and severity of headaches and sleep quality before and 12 weeks after prophylactic treatment with either propranolol or amitriptyline.

Results:

Baseline Visual Analogue Score (VAS) in migraine patients was 7.99 ± 1.39 compared with 6.86 ± 1.50 in TTH group (P < 0.001). VAS score after the first month of treatment was 6.08 ± 1.88 in migraine patients and 5.40 ± 1.61 in TTH (P = 0.023). VAS scores decreased after the third month of treatment to 4.32 ± 2.29 in migraine patients and 4.11 ± 1.66 in TTH patients (P = 0.344). The decrease was significant for patients treated with amitriptyline but not for those with propranolol. Baseline Pittsburgh Sleep Quality (PSQI) scores were 5.93 ± 2.43 in migraine patients and 6.71 ± 2.39 in TTH patients. Poor quality of sleep (PSQI ≥ 6) prior to prophylactic treatment was observed in 61.4% of migraine patients and in 77.7% of TTH patients. Comparison of PSQI scores before and 3 months following treatment showed significantly improved quality of sleep in all treatment groups; the greatest significance was detected in migraine patients with initial PSQI scores of ≥6 and treated with amitriptyline (P < 0.001).

Conclusions:

Increased understanding of routine objective sleep measures in migraine patients is needed to clarify the nature of sleep disturbances associated with primary headaches. This may in turn lead to improvements in headache treatments.     

Cutaneous CD4+/CD56+ hematodermic neoplasm

CD4+/CD56+ hematodermic neoplasm, formerly known as blastic NK cell lymphoma, is a rare and aggressive neoplasm with a high incidence of cutaneous involvement, risk of leukemic dissemination and poor prognosis. The characteristic features are expression of the T helper inducer cell marker CD4 and the NK-cell marker CD56 in the absence of other T cell or NKcell specific markers. Because of the rarity of this disease, we describe a 48 year old woman suffering from CD4+/CD56+ hematodermic neoplasm on her cheek without leukemic infiltration.     

Thyrotoxic hypokalaemic periodic paralysis in a Turkish population: three new case reports and analysis of the case series

Objective Thyrotoxic hypokalaemic periodic paralysis (THPP) is an uncommon condition with intermittent episodes of muscle weakness and occasionally severe paralysis. THPP is a common complication of hyperthyroidism in Asian populations, and has also been reported in other ethnic groups including Caucasians. This study aimed to conduct an analysis of THPP in a Turkish population, and is to our knowledge the first analysis of a homogeneous Caucasian group. Subjects Forty cases with THPP were identified in the Turkish population. Three out of the 40 were new cases and were assigned as index cases. Two cases were not included in the analysis because of lack of data. Results THPP was diagnosed in 10 cases during the first attack and was observed to have a significant shorter complete recovery time statistically in this group (P < 0·01). The majority of cases were hypokalaemic, while there were two normokalaemic cases. Classification of the cases according to their potassium (K) levels revealed that the group with K levels < 2·5 mEq/l had a statistically longer amelioration time than the group with K levels ≥ 2·5 mEq/l. When the cases were classified according to intravenous or oral application of K, the mean amelioration time was 6·8 ± 3·6 h for the intravenous group and 13·1 ± 7·6 for the oral group. Mean complete recovery times of the groups were 29·4 ± 16·2 h and 52·8 ± 18·0 h, respectively. The intravenous group had a shorter amelioration time and complete recovery time, and both were statistically significant (P < 0·05 for each). Conclusions THPP may be seen among Caucasians. Diagnosing THPP during the first attack might decrease the recovery time. The level of hypokalaemia seems to affect the recovery time and initial low K levels may lead to more deterioration in a patient's health compared with mild or near‐normal levels. Intravenous, rather than oral, application of K may be advantageous for shortening both the amelioration and complete recovery times.     

Two cases of duodenal obstruction due to a congenital web

We present two cases of windsock deformity; both were rare in location and one had a rare associated anomaly. In the first case, the windsock was observed in the fourth part of duodenum, causing partial intestinal obstruction. In the second case, the windsock was located in the third part of the duodenum.     

Clinical course of psoriasis patients that discontinued biologics during the COVID-19 pandemic

Background

Since psoriasis is a chronic disease, it is not recommended to discontinue the treatment agents used. However, in real life, the treatment of psoriasis patients may be interrupted for various reasons. During the pandemic period, the treatment of many patients was also interrupted.

Objectives

To evaluate relapse and clinical worsening in psoriasis patients whose biological therapy was interrupted during the pandemic and reveal associated factors.

Methods

The study included patients aged ≥18 years, who were followed up with moderate and severe chronic psoriasis controlled by the last biological agent [Psoriasis Area Severity Index (PASI) 75 response achieved] but had to discontinue their treatment during the pandemic. The patients' demographic and clinical characteristics, clinical course after the discontinuation of these agents, presence of clinical worsening, and relapse were evaluated. Risk factors were analyzed with the logistic regression analysis.

Results

The study included 169 patients, with a mean age of 47.3 ± 14.5 (18–87) years. The mean biologics-free time was 18.2 ± 12.3 (2–56) weeks. Clinical worsening was detected in 41.4% and relapse in 48.5% of the patients. The significant risk factors for clinical worsening and relapse in both univariate and multivariate analyses were alcohol use during the biologics-free period, total time off biologics, and the presence of an additional triggering factor. The use of secukinumab and ustekinumab was found to be a protective factor against clinical worsening in multivariate analyses.

Conclusion

As the biologics-free period is prolonged, the likelihood of clinical worsening and relapse increases, therefore, we do not recommend discontinuing biological agents.     

Primary intraspinal primitive neuroectodermal tumor: case report of a tumor arising from the sacral spinal nerve root and review of the literature

Primary spinal primitive neuroectodermal tumor (PNET) is a rare condition, 18 cases of which have been reported in the literature. In general, this tumor is treated with surgery followed by radiotherapy and chemotherapy, but prognosis is still poor. An 18-year-old female patient with an intradural, extramedullary mass at L3-L5 levels is presented in this report. This is the first female patient with primary spinal PNET at lumbar region, second patient with spinal nerve root origin, and third one with intradural, extramedullary localization ever reported in the literature. After surgery, she was treated with craniospinal radiotherapy and four cycles of combination chemotherapy regimen consisting of vincristine, cyclophosphamide, doxorubicin alternated with ifosfamide, and VP-16. Currently, she is asymptomatic and alive at 25 months. The histopathologic, radiologic, and clinical findings of the patient are presented and relevant literature is reviewed.     

Laparoscopic and abdominal sacral colpopexies: a comparative cohort study

OBJECTIVE: This study was undertaken to compare laparoscopic and open sacral colpopexies for efficacy and safety. STUDY DESIGN: Charts were reviewed for 56 patients who underwent laparoscopic sacral colpopexy and 61 patients who underwent open sacral colpopexy. Demographic and hospital data, complications, and follow-up visits were reviewed. RESULTS: Mean follow-up was 13.5 +/- 12.1 months and 15.7 +/- 18.1 months in the laparoscopic and open groups, respectively. Mean operating time was significantly greater in the laparoscopic versus open cohort, 269 +/- 65 minutes and 218 +/- 60 minutes, respectively (P < .0001). Estimated blood loss (172 +/- 166 mL vs 234 +/- 149 mL; P = .04) and hospital stay (1.8 +/- 1.0 days vs 4.0 +/- 1.8 days; P < .0001) were significantly less in the laparoscopic group than the open group. Complication and reoperation rates were similar. CONCLUSION: Laparoscopic and open sacral colpopexies have comparable clinical outcomes. Although laparoscopic sacral colpopexy requires longer operating time, hospital stay is significantly decreased.     

Assessment of symptom severity and functional status in patients with carpal tunnel syndrome: Reliability and validity of the Turkish version of the Boston questionnaire

Objectives. The aim of this study was to develop a Turkish version of the Boston Questionnaire and assess its reliability and validity.

Methods. Sixty-seven patients with idiopathic carpal tunnel syndrome were included in the study. The Turkish version of Boston Questionnaire was obtained after translation process, and was then administered to subjects twice within seven days. Reliability was assessed by internal consistency (Cronbach's alpha and item-total correlation), and reproducibility. Validity was examined by correlating the Boston Questionnaire scores to general health status (Short Form-36), pain severity (Visual Analogue Scale) and pinch and grip strength measures.

Results. Reliability of the Turkish version was very good, with high internal consistency (Cronbach's alpha 0.82 for symptom severity scale, and 0.88 for functional status scale), and reproducibility (Pearson correlation coefficient 0.60 for symptom severity scale, and 0.77 for functional status scale). The Boston Questionnaire scores were correlated with Visual Analogue Scale, physical functioning, physical role, bodily pain and emotional role subscales of Short Form-36, pinch and grip strength scores to obtain coefficients for external construct validity.

Conclusion. Adaptation of the Boston Questionnaire for use in Turkey was successful. Our results seem to support previous finding of the English version, indicating that it is valid and reliable.
