The coding of the diagnosis The diagnosis of a fracture is obtained by combining its anatomic loca- tion with its morphologic characteristic 150mg clindamycin with amex. An alpha-numeric coding system was chosen to express the diagnosis in order to facilitate computer storage and retrieval order clindamycin 150 mg mastercard. These are followed by a let- ter and two numbers which express the morphological characteristics of the fracture (Fig order 150 mg clindamycin overnight delivery. Starting from this basis discount clindamycin 150 mg with visa, the authors deter- mined that the first logical step was to try to categorize the sequelae of fractures of the proximal humerus. A study of the natural history of the different fractures and how they developed into their sequelae allowed them to understand the lesions that clinically presented later. By studying the initial radiographs and those at later stages, and by reviewing the op- eratives notes, the authors were able to distinguish 4 basic pathologic types of lesions that, when present, dominated the clinical picture and al- lowed the fracture sequelae to be grouped as follows (Fig. Surgical classification of sequelae of proximal humeral fracture: four types of sequelae Type 1: humeral head collapse or necrosis with minimal tuberosity malu- nion. The initial fractures in this group were dominated by 3- and 4- part fractures impacted either in valgus or in varus, leading to slight malunion of the tuberosities. Nonunions of the surgical neck followed either nonoperative 3-part fractures, with rotation of the hu- meral head fragment and significant displacement of the greater tuber- osity, or 2- and 4-part fractures that had undergone primary surgery. The initial fracture was a displaced or dislocated 4-part fracture with disimpaction of the head. The angulation of the fracture were graded as n None n Mild: more than 0 to 158 angulation n Moderate:16to308 of angulation n Severe: more than 308 of angulation The displacement of the fracture were graded as n None n Mild displacement of less than one-third of diameter of the shaft n Moderate displacement of one to two-thirds of the diameter of the shaft n Severe displacement of more than two-thirds of the diameter of the shaft 12 Classifications of scapular fractures 12. This classification is to be geared to anatomical structures and represents an ascending order of the injury severity. With concomitant clavicular fracture the coracoclavicular and coracoacromial ligaments remain intact. Site of fracture: n Anatomical neck n Surgical neck n Surgical neck+glenoid cavity Degree of displacement (mm): n <5 n 5±9 n 10±19 n >20 a 12. Chip fragment frac- tures, often seen in shoulder dislocations, are included in this classifica- tion as fracture type 1, with subdivision into two types, depending on whether the size of the fragment is less or equal (type 1 A) or larger (type 1B) than 5 mm when measured directly on the film. Type 1A with a fracture frag- ment of 5 mm or less, and type 1B with a fracture fragment larger than 5 mm. This classification scheme outlines the various mechanisms of injury and fracture patterns that can occur. For the purpose of this discussion, one need consider only whether the glenoid rim or the glenoid fossa is fractured. Fractures of the glenoid rim occur when a laterally applied high energy force drives the humeral head against the glenoid margin. Fracture of the glenoid fossa occurs when a laterally applied high-en- ergy force drives the humeral head directly into the glenoid cavity. The fracture generally begins as a transverse disruption, which then propa- gates in one of several possible directions depending on the vector of the traumatic force. This classification scheme is based on whether these injuries are minimally or significantly displaced. If significant displacement exists, it may be in either the translational or the rotatory plane. Fractures of the glenoid neck may be caused by a direct blow over the anterior or posterior aspect of the shoulder, a fall on an outstretched arm, or a fall on the superior aspect of the shoulder. Displacement may occur if the fracture is complete, with the fracture line exiting through both the lateral and superior scapular margins. If the superior support structures (the clavicle-AC-joint-acromion strut or the coracoid process- coracoclavicular ligaments linkage) are disrupted, displacement is espe- cially likely. The ring is composed of the glenoid process, the coracoid process, the cora- coclavicular ligaments, the distal clavicle, the AC joint, and the acromial process. The complex as a whole maintains a normal stable relationship between the scapula and upper extremity and the axial skeleton, allows limited motion to occur through the AC joint and the coracoclavicular ligaments, and provides a firm point of attachment for several soft-tissue structures. They tend to be minor injuries, however, since such single disruptions usually do not significantly compromise the overall integrity of the complex.

They are now referred to as, rather In 1904, a German ophthalmologist named Eugen von than angiomas. Hippel noted that these retinal angiomas seemed to run in There are four distinct types of VHL, based on the families. Type 1 is characterized by Swedish pathologist, reported a connection between these all VHL-related tumors except those in the adrenal gland. Like angiomas, hemangioblastomas divided into type 2A (without kidney tumors or cysts in are vascular tumors as well. After Lindau noted this asso- the pancreas), type 2B (with kidney tumors and cysts in ciation, there were many more reports describing families the pancreas), and type 2C (adrenal gland tumors only). These findings included cysts and/or tumors in the VHL is inherited in an autosomal dominant manner. This means that an affected person has a 50% chance of In 1964, Melmon and Rosen wrote a review of the current passing the disease on to each of his or her children. More recently, the tumors in the will show signs of the disorder, usually by the age retina were determined to be identical to those in the CNS. If the child begins to lose developmental milestones or appears to stop developing, metabolic test- ing may be done to evaluate for a metabolic condition called Sanfilippo syndrome. Developmental milestones refer to the skills infants and toddlers acquire as they get older, such as smiling, cooing, grasping toys, rolling over, walking, and talking. Weissenbacher-Zweymuller syndrome (WZS) is a genetic form of dwarfism in which affected individuals are born with small, underdeveloped jaws (microg- nathia), cleft palate, short arms and legs (rhizomelia), There is no cure for Weaver syndrome. However, the “dumbbell” shaped arm and leg bones, protruding wide symptoms that cause problems can be treated and man- spaced eyes (hypertelorism), and incompletely formed aged.

CPT-I Prognosis deficiency affects lipid metabolism in the liver, with seri- ous physical symptoms including coma and seizures. The prognosis of children with cardiofaciocutaneous Two types of CPT-II deficiency are similar in age of onset syndrome depends on the severity of the symptoms and and type of symptoms to CPT-I deficiency. Preventive measures and treatments are available relatively recently, very little is known regarding the level for CPT-I deficiency, and the muscle form of CPT-II of functioning and the average life span of individuals deficiency.

Hypoketosis combined with hypoglycemia in a child can lead to weakness, seizures, and coma. It is not yet clear why some carriers which do not require CPT-I to produce energy.
