Transient ischemic liver injury and respiratory failure in a COVID-19-positive patient after multiple bee stings.

We present a patient with multiple bee stings who developed lung and liver injuries and subsequently tested positive for coronavirus disease 2019 (COVID-19). A 65-year-old male patient presented to the emergency department after being stung by more than 100 honeybees. His physical examination revealed pustular lesions distributed across his chest, arms, back, legs, and head, marking the sting zones. While the patient had no history of liver disease, initial laboratory test results showed elevated liver enzyme levels. A chest computer tomography scan was ordered, revealing bilateral ground-glass opacities suggesting COVID-19. His condition worsened over the course of the following day, and when he was admitted to the intensive care unit (ICU), his SpO2 decreased to 83% despite oxygen support with a mask. The second polymerase chain reaction test taken in the ICU was positive for COVID-19 infection. After stung with multiple bees, the patient developed acute liver injury and suffered from concomitant COVID-19-related respiratory insufficency, and he was treated accordingly. Starting on the 5th day, the patient's liver markers began to improve, and on the 13th day, he was discharged with normal vital signs and liver enzyme values. There seem to be varying outcomes across different studies with regard to the relationship between bee stings and COVID-19. Further research is needed to explore the possibility of this complementary treatment with bee venom in the prevention of severe acute respiratory syndrome coronavirus-2 infection.

Hemodialysis treatment for poisoning patients in the emergency department.

INTRODUCTION: We aimed to evaluate the hemodialysis (HD) use in adult patients after acute poisoning in the emergency department. METHODS: The study was performed as a retrospective observational cohort study. We analyzed hospital electronic data system and patient files. RESULTS: A total of 55 patients were included in the study. Among the 10 toxins exposed, the most common were methanol and metformin. The most common indications for HD treatment were: 67.3% (n = 37) for toxin elimination, 20% (n = 11) for treatment-resistant metabolic acidosis, hemodynamic disorder. The most common complication (50.9%) in all patients was central nervous system depression. Ten patients died from ingestion of methanol, one of aluminum phosphide, and one of opioid-sympathomimetic-hallucinogen agents. CONCLUSION: HD is the most commonly used extracorporeal treatment method in the treatment of poisoning patients. HD should be considered without any delay in treating poisoned patients if there is no response to conventional treatments.

The efficacy of hemogram parameters in the differential diagnosis of renal colic and acute appendicitis in the emergency department.

BACKGROUND: To investigate the efficacy of WBC, PLR and NLR for use in the differential diagnosis of acute appendicitis and renal colic in the emergency department. METHODS: This study was conducted after consent was received from the Cukurova University Medicine Faculty Noninvasive Clinical Research Ethics Committee. In this study, 440 patients for whom file data could be accessed in the hospital automation and archive system who were admitted to the hospital with abdominal pain were included. RESULTS: Of the 440 patients included in this study, 59.5% were male and 40.5% were female. The average age of the patients was 37.74±13.39 years. According to the pathological diagnosis, 207 patients were diagnosed with acute appendicitis. When the efficacy of differential diagnosis using hematological parameters was examined with ROC analysis, the neutrophil/lymphocyte ratio (NLR) value had the strongest predictive ability (AUC, 0.716, SS=0.024, 95% GA 0.668-0.764). After NLR, the platelet/lymphocyte ratio (PLR) value was the second-best concerning predictive ability for differential diagnosis (AUC, 0.608 SS=0.027, 95%, GA 0.555-0.661). CONCLUSION: Patients with acute appendicitis and renal colic often present to the emergency department with abdominal pain. While patients with acute appendicitis are usually treated with surgical methods, medical treatment is used for renal colic in the acute period. The differential diagnosis of these two patient groups is important. We believe that the PLR and NLR values can be used when an exact differential diagnosis cannot be made.

Evaluation of Nutrition Risk in Patients Over 65 Years of Age With Nontraumatic Acute Abdominal Syndrome.

BACKGROUND: The objective of this study is to investigate the power of CRP/Albumin ratio, NRS-2002, mNUTRIC scores to predict nutritional needs and mortality in patients over 65 years of age diagnosed with acute abdominal syndrome in the emergency department and then transferred to the surgical intensive care unit. MATERIAL AND METHOD: CRP/Albumin ratio, APACHE II, SOFA, NRS-2002 and mNUTRIC scores were calculated. The analysis of the data was conducted in IBM SPSS Statistics Base 22.0 package program. RESULTS: In the analytical evaluation made for nutritional needs, AUC value for mNUTRIC was found to be: 0,683, 95% CI 0,611-0,755, p < 0.001. It was found out that mortality of patients had a statistically significant and moderate correlation with mNUTRIC score (r = 0.537; p < 0.001). In the analytical evaluation made for mortality, mNUTRIC's AUC value (AUC: 0.808, 95% CI 0.736-0.880, p < 0.001) was found to be the highest. When the cut-off value determined to predict mortality was taken as 3.5 for mNUTRIC score, sensitivity was 75.9% and specificity was 69.4%. CONCLUSION: The evaluation of the risk of malnutrition through nutritional risk tools in intensive care patients over 65 years of age with acute abdominal syndrome can also predict nutritional needs in the early period besides mortality. Based on our data, the fact that mNUTRIC score cut-off value in older patients hospitalized in intensive care is 3.5 and higher may be a predictor for ICU mortality.

Subdermal nitrous oxide delivery increases skin microcirculation and random flap survival in rats.

Random skin flaps are essential tools in reconstructive surgery. In this study, we investigated the effect of subdermal nitrous oxide (N2O) application on random flap survival. In this experimental study, we used 21 female rats in three groups. In the N2O and air groups, gases were administrated under the proposed dorsal flap areas daily for seven days. Following the treatment period, flaps were raised and inserted back into their place from the dorsal skin. In the control group, the flaps were elevated and inserted back to their place without any pretreatment. Calculation of necrotic flap areas, histological examination and microangiography was performed to evaluate the results 7 days after the flap surgery. The average of necrotic flap area in the N2O, air and control group was 13.45%, 37.67% and 46.43%, respectively. (N2O vs air p = .044; N2O vs control p = .003). The average number of capillary formations identified in the histological analysis was 7.0 ± 1.58, 3.75 ± 2.36 and 4.4 ± 0.54 in the N2O, air and control group, respectively. (N2O vs air p = .017; N2O vs control p = .037). The average number of capillary structures identified in the angiography images were 6.3 ± 1.52, 1.6 ± 1.15 and 1.3 ± 0.57 in the N2O, air and control group, respectively. (N2O vs air p = .04; N2O vs control p = .02). We conclude that subdermal N2O application increases random flap survival through an increase in the skin microcirculation and could be promising for future clinical applications.

A system for endoscopic mechanically scanned localized proton MR and light-induced fluorescence emission spectroscopies.

Molecular and near-cellular modalities offer new opportunities in assessing living tissue in situ, and multimodality approaches, which offer complementary information, may lead to improved characterization of tissue pathophysiology benefiting diagnosis and focal therapy. However, many such modalities are limited by their low penetration through tissue, which has led to minimally invasive trans-cannula approaches to place the corresponding sensors locally at the area of interest. This work presents a system for performing localized fluorescence emission and proton magnetic resonance (MR) spectroscopies via endoscopic access. The in-house developed side-firing 1.9-mm wide dual-sensor integrates a three-fiber optical sensor for fluorescence emission optical spectroscopy and a 1-mm circular radiofrequency (RF) coil for localized MR proton spectroscopy. An MR-compatible manipulator was developed for carrying and mechanically translating the dual-sensor along a linear access channel. The hardware and software control of the system allows reconfigurable synchronization of the manipulator-assisted translation of the sensor, and MR and optical data collection. The manipulator serves as the mechanical link for the three modalities and MR images, MR spectra and optical spectra are inherently co-registered to the MR scanner coordinate system. These spectra were then used to generate spatio-spectral maps of the fluorophores and proton MR-signal sources in three-compartment phantoms with optically- and MR-visible, and distinguishable, materials. These data demonstrate a good spatial match between MR images, MR spectra and optical spectra along the scanned path. In addition to basic research, such a system may have clinical applications for assessing and characterizing cancer in situ, as well as guiding focal therapies.

MR-based real time path planning for cardiac operations with transapical access.

Minimally invasive surgeries (MIS) have been perpetually evolving due to their potential high impact on improving patient management and overall cost effectiveness. Currently, MIS are further strengthened by the incorporation of magnetic resonance imaging (MRI) for amended visualization and high precision. Motivated by the fact that real-time MRI is emerging as a feasible modality especially for guiding interventions and surgeries in the beating heart; in this paper we introduce a real-time path planning algorithm for intracardiac procedures. Our approach creates a volumetric safety zone inside a beating heart and updates it on-the-fly using real-time MRI during the deployment of a robotic device. In order to prove the concept and assess the feasibility of the introduced method, a realistic operational scenario of transapical aortic valve replacement in a beating heart is chosen as the virtual case study.

Sternocleidomastoid region restoration with lateral hemisoleus muscle incorporatied in free fibular flap for reconstruction of radical neck dissection and hemimandibulectomy.

In the treatment of head and neck carcinoma, radical cervical lymphadenectomy leaves the affected side of the neck devoid of the sternocleidomastoid muscle, thus more vulnerable to the unwanted side effects of the adjuvant radiotherapy. It also causes asymmetry and cosmetically unpleasant appearance of the cervical region. In the reported case with widely ulcerated squamous-cell carcinoma over mandible, hemimandibulectomy and radical neck dissection was performed. Following the mandibular reconstruction, the lateral hemisoleus muscle of the harvested osteomyocutaneous fibula flap was utilized to restore the ipsilateral sternocleidomastoid region. This new application promises to be a useful method, which can aid in the restoration of the aesthetic contour of the neck and provide protection against unwanted effects of the adjuvant radiotherapy on the ipsilateral carotid artery.

Simulations and experimental demonstration of coupling molecular and macroscopic level modalities with a robotic manipulator.

Established and emerging molecular and cellular modalities, such as optical imaging and spectroscopy, offer new opportunities for assessing tissue pathophysiology in situ. A challenge with such applications is their limited tissue penetration and low sensitivity that can be addressed with trans-needle or trans-catheter access. In this work, we describe the use of an actuated manipulator to physically manipulate such sensors to scan an area of interest generating 1-D scans while registering them to a guiding modality. Simulations were performed for a miniature RF coil to determine the voxel size, and experimental studies were conducted using a miniature RF coil manipulated by the MR-compatible device. The experimental results on phantom studies show that potential diagnostic information can be collected by using this methodology. This system was pursued to address a critical limitation of emerging molecular and near-cellular modalities; the limited tissue penetration.

Injury patterns and psychological traits of patients with self-inflicted wounds produced by punching glass.

BACKGROUND: Self-inflicted injuries are among the preventable forms of hand injury. Psychologic factors underlying these injuries have not been studied sufficiently. This study aims to reveal the extent of injury and the morbidity as well as the psychologic factors in a population of patients who intentionally injured themselves by punching glass. METHODS: Patients seen and treated for glass punching injuries during a 4.5-year period were reviewed. The demographic data included the extent of injury, postoperative hospitalization time, and full recovery time. Their psychologic traits were analyzed by two questionnaires (Symptom Distress Check List and State-Trait Anger Expression Inventory) and through a psychiatric interview. The results were compared with a sex- and age-matched control group with accidental hand injuries. RESULTS: The study group consisted of 36 patients. Mean age was 24.7 years. Most were men (n = 28), not married (n = 28), and living with their families. Half of them were unemployed. Twelve had only skin lacerations. The remaining 24 patients had a total of 45 tendon, 15 nerve, and 9 artery injuries. On an average, 46 days were required for full recovery. A second attempt of self-infliction was not reported. Twenty-one patients underwent questionnaires and psychiatric interview. The study group felt significantly higher levels of psychologic distress and hostility (p = 0.018 and p = 0.002, respectively). They also had higher levels of anger in daily life (p = 0.002). Clinical psychiatric evaluation failed to reveal any significant psychiatric disorder. CONCLUSION: Self-inflicted hand injuries increase the workload of emergency services and clinics involved in the treatment. Prevention is very difficult, especially when alcohol is not an underlying cause. A typical patient has hostile and disobedient characteristics and who easily expresses his anger. Happily, having suffered enough during their treatment these patients do not attempt a second self-infliction.

Lipofibromatous hamartoma of the median nerve.

Lipofibromatous hamartoma is a rare tumor-like overgrowth of fibroadipose tissue surrounding the nerves. Most commonly, it involves the median nerve. The tumor is usually present at birth and grows very slowly. The expected age of clinical presentation is the third or fourth decades of life. The case reported here had a rapid overgrowth and presented at the age of eight. Our case is the first reported case of lipofibromatous hamartoma of the median nerve in the pediatric age group.

Aberrant perfusion of the serratus anterior muscle flap: report of two cases and a review of the literature.

Free serratus anterior muscle flap, classified as Mathes-Nahai type III, is a versatile and frequently preferred choice for soft tissue coverage of small to moderate-sized defects owing to its reliable circulation pattern; however, some anatomic variations in the flap vascularity can result in partial flap loss. Here we present two cases with free serratus anterior muscle transfer where the distalmost portion of the flap was not perfused by the thoracodorsal pedicle. The most likely explanation seems to be the large flap size and the lack of distal interconnections between lateral thoracic artery and thoracodorsal artery branches. Our clinical experience suggests that anatomic variations of serratus anterior muscle circulation might end up with distal perfusion loss if a large flap is to be harvested.

Analysis of flow changes to the foot after sacrifice of one of the major arteries.

The objective of this study was to find out whether a compensatory increase in blood flow to the foot is observed after sacrifice of one of the tibial arteries. Eleven patients who had one of the tibial arteries as the recipient artery of free tissue transfer to their lower extremities were included. The arterial diameter, cross-sectional area, maximum flow velocity, minimum flow velocity, and flow rate were measured by a Doppler ultrasound in the nonrecipient tibial artery and perforating peroneal artery in the operated limb. The same parameters were measured in the anterior and posterior tibial arteries and the perforating peroneal artery in the contralateral limb. The arterial diameter, cross-sectional area, flow velocity, and flow rate were increased significantly in the nonrecipient tibial artery of the operated limb with respect to the same artery on the contralateral limb. The same changes were not demonstrated in the perforating branch of the peroneal artery. Total blood flow to the foot in the operated extremity was not different from that of the nonoperated foot. The results reveal that if a major feeder to the foot is sacrificed, the other tibial artery compensates for it, and resting blood supply to the foot is not altered.

Digital blocks with and without adrenalin: a randomised-controlled study of capillary blood parameters.

This study compared fingertip capillary blood gas parameters before and after digital anaesthesia using lidocaine with and without Adrenalin. Twenty patients who underwent surgery on their fingers under digital ring block anaesthesia were randomly anaesthetised with 2% lidocaine or 2% lidocaine with 1:80,000 Adrenalin. Capillary blood parameters were measured prior to the digital blocks and 15 minutes after the injections. In the plain lidocaine group, PO2 and SaO2 increased significantly after injection (P = 0.025 and 0.017, respectively). In the lidocaine with Adrenalin group, PO2 and SaO2 decreased after the injections. However, this decrease was not statistically significant. Patients in the plain lidocaine group had return of sensation to the finger tip 4.8 (+/-0.6) hours after the operation. This period was 8.1 (+/-0.8) hours for the lidocaine with Adrenalin group.

Effects of cyanocobalamin on immunity in patients with pernicious anemia.

OBJECTIVE: The aim of the study was to evaluate the role of vitamin B(12) in patients with pernicious anemia. MATERIALS AND METHODS: This study was conducted prospectively at the Turgut Ozal Medical Center, Department of Hematology, between April and November 2002. Absolute numbers and ratio of the surface antigens of T and B lymphocyte subgroups, CD4/CD8 ratio were calculated in order to evaluate changes in leukocyte and lymphocyte numbers; natural killer (NK) cell count, serum C3, C4, and levels of immunoglobulins G, A, and M were also measured to evaluate vitamin B(12) effect on immunity. Values obtained before treatment with cyanocobalamin were compared with those found during peak reticulocyte count. RESULTS: In vitamin B(12)-deficient patients, absolute numbers of CD4+ and especially CD8+ lymphocytes were found to be decreased; CD4/CD8 ratio increased, and NK cell activity was depressed. After cyanocobalamin treatment, absolute numbers and percentage of lymphocyte subgroups were elevated. Increased CD4/CD8 ratio and depressed NK cell activity were restored and levels of C3, C4, and immunoglobulins were elevated. CONCLUSION: These findings suggest that vitamin B(12) has important immunomodulatory effects on cellular immunity, and abnormalities in the immune system in pernicious anemia are restored by vitamin B(12) replacement therapy.

Patients' perspectives on the ocular symptoms of facial paralysis after gold weight implantation.

SUMMARY: Upper lid loading for the treatment of lagophthalmos resulting from facial paralysis is a simple and effective procedure with relatively few side effects and complications. A detailed patient-based self assessment, focusing on subjective complaints after upper lid weight implantation is scarce. In this study, a population of facial palsy patients with lid weights is asked about their subjective complaints in order to find out the patients' point of view. Patients with upper lid weights were asked questions indicating the degree of soreness, tearing, redness, visual acuity, lid closing during the day, lid closing during sleep, aesthetic appearance, artificial tear utilisation and outdoor comfort. All questions were evaluated by an analogue scale in reference to the opposite eye, where a score of '10' corresponds to the best outcome (no symptoms at all or appearance comparable to the contralateral eye) and a score of '1' corresponds to the worst outcome. Thirty patients filled in the questionnaire and 22 of them were seen in the outpatient clinic. The most pleasing result was obtained in the lid closing during the day (score 8.8+/-1.9), during sleep (7.7+/-3.0) and in the aesthetic appearance of the eye (score 7.6+/-2.7), whereas visual acuity received the lowest score (score 5.7+/-1.5). Complication and re-operation rates were 23% and 13%, respectively. In conclusion, upper lid weights solve the problem they are used to address. They provide a satisfactory lid closure and aesthetic appearance in the patients' point of view. However, the ocular symptoms of facial paralysis still persist to some extent and the procedure is not without its complications.

Computed tomography in the management of cervical lymph node pathology.

Computerised tomography (CT) is a useful adjunct in the diagnosis of cervical pathology in head and neck carcinoma. However, different criteria used in CT analysis make the comparison of outcome studies difficult. This study compares two different CT criteria (two different lymph node sizes) for detection of cervical lymph node pathology for head and neck tumours in the same patient population. A prospective study was performed on 55 patients, with minimum T2 intraoral squamous cell carcinoma and high risk extraoral malignancies, who underwent 65 neck dissections. Sensitivity, specificity and accuracy of clinical palpation, CT considering lymph nodes larger than 10mm as positive and CT considering lymph nodes larger than 15 mm as positive are compared. The results are as follows: sensitivity, specificity and accuracy of clinical palpation are 86, 84 and 85%, respectively; sensitivity, specificity and accuracy of CT with lymph nodes exceeding 10 mm are 95, 47 and 63%, respectively; sensitivity, specificity and accuracy of CT with lymph nodes exceeding 15 mm are 86, 81 and 83%, respectively. The outcomes of the study reveal that CT evaluation of cervical lymph nodes with a cutoff value of 15 mm should be preferred to a cutoff value of 10mm in order to prevent over-treatment in cervical management of head and neck tumours. When accuracy of the results is considered, CT alone does not have an advantage over clinical palpation in this study.

Atypical midline cleft with duplication of the metopic suture.

INTRODUCTION: In contrast to the common clefts of the lip, alveolus and palate, the atypical clefts of the face may come in myriad patterns of clinical expression and are often not easy to define. PURPOSE: In this report, a case of median craniofacial dysraphia is described. PATIENT: At presentation, the 3-month-old male patient had a bilateral complete cleft of the lip, alveolus and palate. The nose was wide and a horn was present on the nasal dorsum. 3-D CT AND MRI REVEALED: Duplication of the metopic suture ending at the wide anterior fontanel; orbital hypertelorism; midline cranial cleft ending just superior to the nasal dorsum; frontoethmoidal encephalocoele and holoprosencephaly. The presence of two metopic sutures was confirmed during surgery. CONCLUSION: The presented case carries the characteristics of the median cleft face syndrome. However, it differs from similar cases in two respects. First, the patient had two metopic sutures, one on either side of the cranial extension of the median cleft. Second, the patient had a bilateral cleft lip in contrast to the expected median cleft lip deformity.
