Treatment of chronic subdural hematoma (CSDH) is relatively straightforward, however, there is still some debate regarding the best strategy for treatment. The most practical recommendations of up to date were identified by a review of literature. The author reviewed the literature on CSDH management from the past to now to identify the best methods. Till 1970s, craniotomy was the most commonly used method. Burr hole (BH) became the most preferred method from 1980s. In 1977, twist drill (TD) craniostomy was introduced. Closed system drainage after a BH or a TD became the most frequently used surgical method. Although nonsurgical treatment is often successful, trephination has more advantages, such as rapid resolution of the symptoms and short period of hospitalization. Nonsurgical treatment is possible in asymptomatic patients with a small CSDH. For the symptomatic patients with CSDH, trephination is the treatment of choice, either by BH or TD. In gray zone between surgery and medical treatment, shared decision making can be an ideal approach. For the recurrent CSDHs, repeated trephination is still effective for patients with a low risk of recurrence. If the risk of recurrence is high, additional management would be helpful. For the refractory CSDHs, it is necessary to obliterate the subdural space.

Recently, the survival of the high-risk population of preterm infants has steadily improved, and the severity of prematurity is a growing threat of gestational-age-related fatal conditions. Posthemorrhagic hydrocephalus (PHH) is the most common but serious neurological complication in premature infants, which can have life-threatening consequences during the acute phase in the neonatal period and life-long psychomotor and cognitive sequelae in their later life. Although neonatologists, pediatric neurologists, and pediatric neurosurgeons have investigated a diversified strategy for several decades, a consensus on the best management of PHH in premature infants still must be reached. Several approaches have tried to reduce the incidence of intraventricular hemorrhage (IVH) and mitigate the effect of IVH-related hydrocephalus. This paper reviews and discusses the clinical feature of PHH in premature infants, general/nonsurgical management of prematurity for IVH prevention, and posthemorrhagic management, and how and when to intervene.

An estimated 250 million people worldwide suffer from lymphedema. In the past, the first-line option for treatment was nonsurgical management, either in the form of compression garments or wrapping, or comprehensive decongestive therapy, with debulking surgery reserved for the more advanced cases. However, with improvements in microsurgical techniques and imaging modalities, surgical intervention is increasingly being utilized. This review highlights recent advancements in the surgical treatment of lymphedema, specifically focusing on improvements in imaging, surgical techniques, and prevention of lymphedema.

As long as the prognosis of teeth remains a matter of concern, the endodontic-periodontal relationship will be considered a challenge for the clinician. Many etiologic factors, including bacteria, fungi, and viruses, plus other contributing factors, such as trauma, root resorptions/perforations, and dental malformations, play a role in the co-occurrence of endodontic and periodontal lesions. Whatever the cause, a correct diagnosis on which to base the treatment plan is the key to successful maintenance of the tooth. This article reports the successful endodontic management of a furcation lesion in a mandibular molar that was nonresponsive to a previous periodontal surgical graft. The case had presented a diagnostic challenge for the clinicians, and this article reviews the key points that can lead to a correct diagnosis and treatment planning.

Objective : The prognosis of spontaneous intracerebral hemorrhage often depends on initial neurologic condition, size and location of hemorrhage and associated intraventricular hemorrhage. However, age of patient, coagulation state and other associated vascular diseases may also play a role when present. In recent years, the geriatric population has been increasing. The age distribution of the patients with intracerebral hemorrhages also has been increased, accordingly. However, such patients, especially when associated with poor initial conditions often tend to be managed rather conservatively. The authors analyzed retrospectively on forty-five patients with spontaneous intracerebral hemorrhage over the seventies with poor initial condition to find out whether there exists a difference of outcome between surgery and non-surgery group. Material and Method : A total of 45 patients over seventies with spontaneous intracerebral hemorrhage with Glasgow Coma Scale(GCS) 4-8 treated over last six years were included. The validity of surgical management for these patients as well as clinical variables which might have been operated on the outcome of these patients were evaluated. The Glasgow Outcome Scale(GOS) after three months was used for comparison of outcome. Results : In surgical group(19 cases), mean age was 74.5 years old, mean hematoma volume 67.2ml and mean GCS score 5.7 points. In nonsurgical group(26 cases), mean age was 79.3 years old, mean hematoma volume 32.1ml, and mean GCS score 6.8 points. Mortality rate in surgical group was 47.4%(9 patients), including 2 cases of post-operative rebleeding, while that in nonsurgical group was 46.2%. However, when patients with initial GCS 4-6 points and over 30ml in hematoma volume were regrouped, mortality rate in surgical group was 46.2%, whereas mortality rate in nonsurgical group was 66.7%. Conclusion : It is concluded that the mortality rate is much low in surgery group with initial GCS less than 6 points and hematoma volume over 30cc. There was no significant difference of outcome in patients with basal ganglia and thalamic hemorrhage. However, surgical treatment lowered the mortality and morbidity rate in patients with subcortical and cerebellar hemorrhage.

The aim of this study was to present a method for endodontic management of a maxillary first molar with unusual C-shaped morphology of the buccal root verified by cone-beam computed tomography (CBCT) images. This rare anatomical variation was confirmed using CBCT, and nonsurgical endodontic treatment was performed by meticulous evaluation of the pulpal floor. Posttreatment image revealed 3 independent canals in the buccal root obturated efficiently to the accepted lengths in all 3 canals. Our study describes a unique C-shaped variation of the root canal system in a maxillary first molar, involving the 3 buccal canals. In addition, our study highlights the usefulness of CBCT imaging for accurate diagnosis and management of this unusual canal morphology.

Background To date, there are no consensus guidelines for management of lymphatic leak in groin vascular reconstruction patients. The goal of this study is to review the relevant literature to determine alternatives for treatment and to design an evidence-based algorithm to minimize cost and morbidity and maximize efficacy. Methods A systematic review of the literature was conducted per Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. Two independent reviewers applied agreed-upon inclusion and exclusion criteria to eligible records. Studies that included patients who underwent groin dissection for oncologic diagnoses and level 5 data were excluded. Interventions were then categorized by efficacy using predetermined criteria. Results Our search yielded 333 records, of which eight studies were included. In four studies, the success of lymphatic ligation ranged from 75% to 100%, with average days to resolution ranging from 0 to 9. Conservative management in the form of elevation, compression, and bedrest may prolong time to resolution of lymphatic leak (14-24 days) and therefore cost. Conclusions The majority of patients should be offered early operative intervention in the form of lymphatic ligation with or without a primary muscle flap. If the patient is not an operative candidate, a trial of conservative management should be attempted before other nonsurgical interventions.

Fusion of teeth is a developmental anomaly. It occurs at the stage of tooth formation, which determines the shape and size of the tooth crown, when one or more teeth fuse at the dentin level during the morphodifferentiation of the dental germs. Such teeth show macrodontia and may cause crowding, as well as esthetic and endodontic problems. In this article, we report a rare case of a maxillary central incisor fused to a supernumerary tooth showing labial and palatal talon cusps, which was orthodontically moved across the midpalatal suture. A 13-year-old Caucasian boy sought treatment for the unesthetic appearance of his maxillary central incisor and anterior crowding. He was rehabilitated successfully via a multidisciplinary approach involving orthodontic, nonsurgical endodontic, periodontal, and prosthodontic treatments. After a 26-month treatment period, the patient's macroesthetics and microesthetics were improved. The overall improvement of this macrodontic tooth and its surrounding tissues through multidisciplinary treatment was documented using cone-beam computed tomography.

Non-neurogenic pediatric voiding dysfunction is defined as a problem during bladder filling or emptying without any neurogenic abnormality in children. The appropriate treatment of non-neurogenic pediatric voiding dysfunction is important because the disorder is frequently seen in clinical practice and might result in damages of the child's bladder or kidney. Urotherapy can be defined as nonsurgical nonpharmacological treatment for voiding dysfunction, categorized into standard urotherapy or specific intervention. Understanding of the underlying pathophysiology of non-neurogenic pediatric voiding dysfunction will lead to a change in management, from expensive and potentially harmful medications and invasive procedures to effective, noninvasive treatment of urotherapy.
